Introduction National Construction Company is considered as one of the largest and most prestigious companies operating in construction field.

3 Introduction National Construction Company is considered as one of the largest and most prestigious companies operating in construction field. Since we have established in 1994, we have taken a main trend in bridges construction and rehabitation in addition to many other activities that serves in roads, railways, airports, train bridges and whole related files. As one of our main objectives is to be a forerunner in bridges construction requirements provider and desiner; In 2012, had started to manufacture the elastomeric bearings & the expansion joints through its sister company HANOTEX for Rubber & Plastic Industries which has a very reputable name in Egypt & MENA region since 1978 as a manufacturer of technical rubber products. In the last few years & HANOTEX delivered thousands of bearings & joints to hundreds of projects in Egypt, and succeeded to build a reputable brand in that sector. Due to the distinctive location of factory & the extended manufacturing facilities, it takes only few days of delivery to any market in MENA region with a free import taxation privilege to many countries. With a strong quality system applied on the basis of ISO9001 management system & a products certified for CE mark, we guarantee to provide a high quality products to our customers & partners in success. 2

4 Product Quality ensures the quality of its products through applying a very strict factory production control system, and confirms this quality by applying several testing for the product internally & externally in many national & international laboratories. Testing products in Tzus laboratory in Czech Republic Testing products in MPA laboratory in Germany In-house testing facilities W & F 500 ton testing press In-house testing facilities External audit for CE - certified bridge bearings In-house testing tacilities 3

5 Elastomeric Bearings What Is Elastomeric Bearing? Elastomeric bearing is an elastomeric rubber block laminated with reinforcing steel plates that are vulcanized when built to provide a high permissibility of heavy loads. As an elastic product, Elastomeric bearing allows ; 1. Vertical compression deformetion 2. Shear deformation to satisfy horizontal deformation 3. Rotational deformation as shwon in figures It also has perfect antivibration for reducing impact & dynamic load effect. Vertical Compressive Load Horizontal Rotational Deformation As a durable, reliable, light, small & easy to maintained product, the elastomeric bearings became a perfect solution for the designers in many construction applications. 4

Types of Bearings & Usage AS defined in the European Standard EN 1337-3, Elastomeric Bearings can be provided in different shapes & types to fit with the designers requirements as shown below

bearings with outer steel plates that allows fixing with external anchoring system, which is offered by Used especially for steel beams with occasional, temporary and irregular traction

6 Types of Bearings & Usage AS defined in the European Standard EN , Elastomeric Bearings can be provided in different shapes & types to fit with the designers requirements as shown below Type A: Laminated bearings with only one steel reinforcing plate Type B: Laminated bearings fully covered with elastomer with at least two steel reinforcing plates Type C - C2: Laminated bearings with outer steel plates that allows fixing with external anchoring system, which is offered by Used especially for steel beams with occasional, temporary and irregular traction forces Type C - C4: Laminated bearings with outer checkered steel plates to allow high friction with the construction They are designed for both cast-in-situ concrete and precast concrete elements. Type D: Type B with PTFE sheet bonded to elastomer Type E: Type C with one outer plate ponded to the elastomer and PTFE sheet recessed in the steel Type F: Plain pad bearings & strip bearings This bearing can be provides in long strip & then cut to length provides all the types specified in the EN standard and also can provide any additional shapes as required from our clients 5

7 Elastomeric Bearings Aspects and Architecture Elastomeric bearings are produced in rectangular, square & circular shapes for all types Constraining Movement In normal conditions, elastomeric bearings allow the horizontal movement in both plan directions X & Y. But according to the requirement of the designer, the movement can be restrained in one direction or in both directions to allow only the vertical displacement & rotation provides the restrained bearings in different designs according to the requirement of designer. Elastomeric Bearing Restrained in two directions Elastomeric Bearing Restrained in one direction 6

8 Material Specifications The elastomeric material used is a compound from either Natural Rubber (NR) that provides a high performance against compressive & shear loads or Synthetic Poly Chloroprene Rubber (CR) that got a very good aging characteristics, as per the design requirements or country regulations. provides a high performance bearings with a body of Natural Rubber (NR) & outer surface of Synthetic Chloroprene Rubber (CR), which combines the advantages of the both materials Physical Properties The Elastomeric material manufactured by complies with the requirement of the international standards such as EN , BS 5400, AASHTO M251-06, etc. The following table identifies the physical properties of rubber as defined in EN Characteristics Requirement Test Method G Modulus (MPa) Tensile Strength (MPa) Moulded Test Piece Test Piece from Bearing ISO 37 Minimum Elongation at break (%) Moulded Test Piece Type 2 Test Piece from Bearing Minimum Tear Resistance (kn/m) ISO 34-1 CR Trouser NR (Method A) Compression Set (%) ISO h ; 70 ºC CR 15 NR 30 Accelerated Ageing (Maximum change from unaged value) Hardness (IRHD) NR 7 d, 70 ºC CR 3 d, 100 ºC ± 5 Tensile Strength (%) NR 7 d, 70 ºC ± 15 CR 3 d, 100 ºC ± 15 Elongation at break (%) NR 7 d, 70 ºC ± 25 CR 3 d, 100 ºC ± 25 Ozone Resistance No cracks Elongation: 30 % - 96 h 40 ºC ± 2 ºC NR 25 pphm CR 100 pphm Ø 29 x 12.5 mm Spacer : % ISO 48 ISO 148 ISO The Steel Reinforcing Plates used in the bearings are of steel grade S 235 according to EN as stated in the standard EN
