3 Ü Ü The PFEIFER Sandwich Anchor System was developed in order to join the facing layer to the load bearing layer of sandwich panels. The advantages of this system are very obvious: Advantages when planning Type approval by the GA Würzburg for all sizes Simple calculation software Simple tables for dimensioning when planning Newest standard of development according to tests and the new DIN (EC 2) and DIN have been included in the type static calculation. The insulation layer can be increased up to! When keeping to the given minimum/maximum distances, it is not necessary to calculate the anchor pins Dimensioning results automatically according to the weight of the facing layer wind loads wind suction and wind pressure and thermal stresses have been already taken into consideration in the type static calculation Advantages for the precast production Reduced labour costs due to easy handling Robust construction ight weight Formwork ad hesion is absorbed loosening of the facing layer is impossible Advantages when assembling No shut down of the building site because type static calculations have been checked for all sizes. Optimal joining of the facing layer to the load bearing layer prevents displacement of these parts. Brief load of the facing layer during installation is possible without appreciable displace - ment equal load capacity of the cylinder anchor in all directions. Advantages for your purchasing department Software Applicable for all usual thicknesses of insulation layers. Reliable delivery through certified company Comprehensive and complete product range Reasonably priced technical solution High quality special steel against corrosion Easy ordering by Fax Form 3 Improved order logic because all parts vary only in height

4 General advice for planning and production of Sandwich Panels!!! Principles The building envelope is the boundary between the interior and exterior, and apart from normal structural requirements it has to resist a variety of other effects. In addition the visual appearance of the facade is the signature of the building. Concrete facades are particularly suitable on account of the wide range of colours and textures available, and the robustness of the concrete. Reinforced concrete sandwich panels are usually large, multi layered, facade elements. In order to meet all requirements, they typically consist of a weather resistant outer layer, an insulating layer, and an internal load bearing layer. In addition it may be required to add an air layer between the insulation and the outer layer, or an external facing of natural stone or similar materials. Since the facade has to withstand both seasonal and short term temperature changes, attention must be paid in the early stages to ensure that all layers can move independently of each other. Failure to do so can lead to induced stresses in the outer layer. To achieve this, a load bearing system is required that will cater for dead loads as well as accoodating thermal and wind loads. PFEIFER Sandwich anchor system The PFEIFER Sandwich anchor system, which is type-approved, provides the load bearing connection between the facing layer and the load bearing layer. When calculating the design requirements, a variety of different conditions are taken into consideration such as dead weight, wind loading, thermal changes in the outer layer, and temperature gradients through the construction. In simple terms the system consists of one or two bearing anchors, a torsion anchor and/or a retaining anchor plus evenly distributed sandwich anchor pins. oad bearing anchor The load bearing anchors are designed to transfer the dead weight of the outer layer onto the inner load bearing layer. They should be arranged in such a way that no constraints are placed on the outer layer. Such constraints could cause cracking and other long term effects which would prevent the outer layer performing its role. Because of this, it is important that only a single stiff connection point exists between the inner and the outer layer. Depending on which system is selected, this connection may consist of a single cylinder anchor, two flat anchors, or a combination of a cylinder anchor and a flat anchor. 4!!! Torsion anchor IIf the only connection is a single cylinder anchor, an additional torsion anchor has to be provided to prevent lateral rotation of the outer layer about the connection point. This torsion may be due to unavoidable eccentricity, or inaccuracies in manufacture. Either a flat anchor or the type-approved connector pin can be used as a torsion anchor. Retaining anchor If a combination of two vertical flat anchors is used to transfer load, then a retaining anchor has to be provided to prevent lateral displacement of the outer layer. This anchor is positioned horizontally and creates the origin for any movement. A flat anchor placed horizontally, or a connector pin may be used for this purpose. Sandwich anchor pins The range of sandwich anchor pins consists of connector pins, clip-on pins and clip-on stirrups. They are installed in a grid pattern depending on the design requirements and cater for wind suction as well stresses due to thermal effects.

5 There are important constructional points to consider in production and planning of sandwich panels, particularly to avoid cracking and visible deformation through shrinking or temperatur expansion. These apply to the way of production, storing, assembly, but also to the principles of planning.!!! Production Conditions For the production of sandwich panels it is most important to observe the following recoendations in order to guarantee high quality production. This particularly concerns protective measures against damage arising from excessive shrinking. A low water-cement ratio should be observed when making concrete, as otherwise serious deformation owing to shrinkage/contraction can be expected. Cement paste and flour-grain proportions should be kept low. Both factors strongly influence the rate of shrinkage of both facing layer and load bearing layer. High quality insulation materials with a low degree of water absorption (e.g. Styrodur) prevent an excessive penetration of water into the insulating material. Too much water absorption in the insulating material would cause the moisture within being emitted during the drying out process, while the exterior would dry thus causing a negative influence on the contraction behaviour. Two layers of insulating material overlapping in their joints prevent excessive penetration of Cement paste in the space between the insulation plates and thus a possible development of a cold bridge. If only one layer insulation material is used, it should be covered additionally with a foil. If possible, the sandwich panels should be manufactured in the positive process (facing layer on top while manufacturing) in order to keep the deformation as small as possible. The shrinkage deformation of facing layer and load bearing layer act in the opposite direction in this case. Excessive compacting should be avoided. Contact of the compactor to the installed inserts can damage the surface of the facing layer. Storing As the way of storing have quite an influence on the measure of shrinkage, it is necessary, particularly at the beginning, to pay attention that the elements are allowed to dry out slowly but evenly. This means that the difference in the process of drying, outside and inside, should be as minute as possible. This can be achieved through observing a few conditions, as follows: The elements should not be subjected to strong sunshine or influence of wind during the first few days as this considerably increases the chance of the individual layers drying unevenly. It might be advisable to keep the elements damp during the first few days. Storing under plastic sheeting in a shady place represents a suitable method of drying the concrete. Assembly and Planing When planning the sandwich panels a cardinal point to be considered is the final alignment and position of the elements respectively, as these have strong influence on exposure to the sun, etc. With simple coitments when planning it is possible to avoid the danger of deformation and so consequent cracking in the exterior facing layer: Determining a low water-cement ratio already at the time of planning. See Production Conditions. Determining suitable storage of the elements (see Storing ). The length of the facing layer should always be limited to 6m. Facing layers of longer elements should be planed with an expandable joint. It should be observed that deformation in plates longer than 5m is probable. A light coloured facing layer is of advantage in strong sunshine. A stronger and stiffer construction of the load bearing layer would have a positive influence on the deformation of the facing layer. The thickness of the facing layer should be at least 70 according to DIN (EC 2). 5

8 Installation Instructions Cylinder Anchor Installation and arrangement of cylinder anchors There are basically two different production processes for sandwich panels. The process is called negative process if the facing layer is lying directly on the formwork and is cast first. It is called positive process if the panel is produced vice versa the load bearing layer lays on the formwork and is produced first. The following instructions refer to the negative process: It has to be checked first if the mesh reinforcement square (minimum Q 188 A) is bigger than the diameter of the cylinder anchor. If this is the case, the anchor can be placed in the middle of the mesh square. The mesh reinforcement has to be cut locally if the diameter of the cylinder anchor is bigger than one mesh square. After that the cylinder anchor is simply placed on the earlier intended position. Figure 1 Figure 2 8 Minimum- and additional reinforcement In the load bearing layer as in the facing layer, minimum surface mesh reinforcement must be installed as well as additional single reinforcement bars besides the cylinder anchor should be used (Table 2 and Installation ). Dependent on the diameter of the cylinder anchor the required additional reinforcement can be determined (Table 2). It consists of reinforcement bars Ø 8, l = 700 and is placed left and right/above and below the anchor (see graphic in Table 2). The additional reinforcement has to be installed and fixed on the front- and on the backside of the mesh reinforcement in the same position as the bars of the mesh reinforcement. The reinforcement bars Ø 6 (Table 1) have to be plugged through the upper and lower hole rows afterwards. After that, the cylinder anchor with the reinforcement bars placed in a right angle to each other has to be turned by 45 in such a way that the anchor lays above and beneath the mesh reinforcement Q 188 A and the additional reinforcement (figure 2). The anchor is now fixed and will not move during concreting. The surface reinforcement was designed only for the anchoring of the sandwich panel anchors. The facing layer must be calculated and reinforced independent from that by the designer. Completion The insulation layer can be installed after concreting the facing layer. It has to be observed that the insulation material in the area of the cylinder anchor is cut carefully to the diameter of the cylinder anchor used. The cut round part must be reinstalled inside the cylinder anchor. It is important that no cavities are formed which could fill up with concrete later, leading to cold bridges. The installation of the insulation material in two layers has been proven advantageous as the splices can be placed shifted this way. The cylinder anchor provides a non-positive connection of the facing layer to the load bearing layer after concreting.

12 Installation Instructions PFEIFER Flat Anchor Figure 4 Figure 5 The installation of the Flat Anchor takes place in three steps. First of all two bars, bent in the centre at an angle of 30 35, must be inserted through the outside holes in the upper row (Fig.4). Then the flat anchor must be positioned on the reinforcement mesh. Two or four more reinforcement bars should then be inserted in the lower row of holes respectively so that they are positioned below the lower layer of the reinforcement steel mesh Figure 6 (Fig.5). To complete the fixture, the Figure 7 bent bars are then turned 90, and fastened with a wire onto the mesh reinforcement (Fig.6). t T Embedment Depth The embedment depth of the Flat Anchor always adapts itself to the thickness of the insulation layer. Conforming to Table 12 the Flat Anchor should be selected and installed according on the chosen thickness of the insulation layer. The embedment depth in the facing and load bearing layer is determined according to the following formula: e V = e T = 0,5 (h D) Figure 8 h e T e V D V Table 11 Method of installation and anchoring Method of Installation ength Reinforcement Bars BSt 500S ,,,, x 4 Ø 6 mit = x 5 Ø 6 mit = x 6 Ø 6 mit = x 7 Ø 6 mit = 400 Both embedment depths must be the same. A greater embedment depth increases the safety against concrete pull out. Thus insulation thicknesses of up to 20 cm are possible. Anchoring Table 11 shows the number of reinforcement bars dependent on the length of the anchor. These reinforcement bars must be installed into the facing- and load bearing layer, in order to guarantee adequate anchoring. 12 Table 12 Dimensioning the necessary anchor height h [] Insulation ayer Thickness D [] H = 150 H = 175 H = H = 225 H = 260 H = H = 300 H =

16 Edge Distances and Distances between the Anchors According to Fig. 9 there is generally a maximum distance of 1,20 m planned between the individual anchors. Therefore it is insignificant whether it concerns Anchor Pins, Flat or Cylinder Anchors. In the case of extremely high adhesive strength as for example in the case of highly structured surfaces of the facing layer, we recoend reducing the maximum distance to 0,90 m. The anchors should be positioned in a square grid, if possible. Otherwise the following ratio aspect I x /I y of the mesh is applicable: 0,67 l x / l y 1,50 In addition to the distance between the individual anchor elements, the distance f (from the flat anchor to the centre of the anchoring in the sandwich plate) must be taken into consideration see Fig. 9. The maximum distance of the flat anchor to the centre of the anchoring can be seen from the dimensioning Table 19. This can be exceeded if the thickness of the insulation layer will be adjusted in proximity to the anchor.

They are used in combination with both PFEIFER Flat and CylinderAnchors and need no special dimensioning when installation regulations are observed.

18 Installation Instructions PFEIFER Connector Pin/Clip-on Pin/ Clip-on Stirrup Figure 10 Figure 11 h b e T e V 10 T D V The types of pins and stirrups are chosen according to the different types of sandwich panels production. Basically it depends simply on whether it is a positive or negative production. For the negative production of sandwich panels the Connector Pin is ideal. After the insulation layer has been put in place, this pin is positioned over a crossing of reinforcement bars of the load bearing layer (Fig.10) so that it is anchored in the facing layer. The Connector Pins must be placed over a reinforcement crossing of the load bearing layer, pressed through the insulation layer into the facing layer till the bottom of its formwork. To prevent the pointed ends of the pins becoming visible on the face of the facing layer later on, the Connector Pins should be withdrawn slightly after having touched the formwork. Pressing them first onto the bottom of the formwork ensures the necessary bond depth e v of the wavy ends 60 (Fig.11). Advice: After the Pins have been completely inserted it is necessary to compact the element once more. In all other cases of application where it is not possible to use the Connector Pins, the Clip-on Pins or Clip-on Stirrups are good alternatives. These should be fastened according to the following figures to the mesh reinforcement and are in this way fixed in position and bond depth.! Dimensioning these anchors is not necessary as long as the installation instructions are observed. Figure 12 Figure 13 Clip-on Pin: Installation Figure 16 Alternative a: Fig. 12 and 13 show how the Clip-on Pin can be hooked in easily. Alternative b: Fig.14 and 15 show a simpler method by using a thick nail. Figure 14 Figure 15 Figure 17 Clip-on Stirrup: Installation The Clip-on Stirrup must be fixed at an intersection of the reinforcement mesh (Fig.16) and then turned into its final position (Fig.17). 18

The edge distances and distances between the anchors according to Fig. 12 (page 14) and Fig. 21 should be observed. The distance of the outer pin from the edge should be between 100 and 300 in order to guarantee a safe anchoring. Should the facing layer overlap the load bearing layer by more than, then two pins must be used together. For the distance between one pin to another the general instructions concerning 1,20 m or 0,90 m respectively are valid. The first pin at the diagonal should also be installed as a double pin as long as a flat anchor has not been installed. The maximum distances of the outer pins to the bearing anchor should be considered when choosing the pins to be used. These maximum distances are dependent both on the insulation layer thickness as well as the diameter of the pin. See here max. measure n according to table 20 and 21 above.

21 Installation instructions Connector pin cross Figure 19 Figure 20 The PFEIFER connector pin crossing consists of two connector pins which are installed at a 45 angle to the surface (Fig. 19) and at 90 to each other. It can be used as an alternative to torsion and retaining anchors. It is forbidden to use the connector pin crossing as a bearing anchor. As in the case of normal connector pins, the installation is carried out simply by penetrating the pins through to the base of the layer after the insulation has been applied. Then, in order to avoid visible signs on the subsequent facade, it should be pulled back somewhat (max. 10 ). Finally the component has to be compacted once again in order to ensure that the pins are anchored properly. Connector stirrups and clip-on stirrups cannot be used for making a pin crossing.

22 Suitable Structural Systems 1) Use of Cylinder Anchors in combination with Flat Anchors 2) When using ONY Flat Anchors Fig. 21 shows the most simple solution of all. The cylinder anchor is installed in the centre of gravity, the Flat Anchor serves as torsion anchor. Figure 21 When long rectangular elements as shown in Fig. 25 are used, then an alternative solution to those according to Fig. 21 and 24 respectively would be the use of three Flat Anchors. In this case two anchors act as bearing anchors, and another Flat Anchor turned by 90 serves as a stiffener in the longitudinal direction. Figure 25 Because of the large open area shown in Fig. 22, the two anchors used must be installed asyetric to the center of gravity. This results in irregular loading of the anchors and disadvantageous maximum distances f and n for the Flat Anchor and Pins. Figure 22 The open area shown in Fig. 26 necessitates the bearing anchor being installed outside the centre of gravity. Combined with a further Flat Anchor, it is possible to achieve a favourable distribution of the load compared to the solution shown in Fig. 23. This also has a positive influence on the maximal distances f and n for the Flat Anchor and Anchor Pins. Figure 26 The large open area for the window in the region of the axis of gravity (fig. 23) makes it necessary to position the anchor outside this axis. This also results in irregular loading of the anchors and disadvantageous maximum distances f and n for both the Flat Anchor and Anchor Pins. Figure 23 This example (Fig. 27) as compared to Fig. 22 results not only in a more favourable distribution of load on the Flat Anchor but also in a much more acceptable maximal distance f and n for the Flat Anchor and Anchor Pins. Figure 27 Fig. 24 shows a more favourable positioning of two anchors. The syetrical position to the axis and the centre of gravity guarantees regular loading of the anchors. Figure 24!
