FR Series Elastomeric Strip Bearing
(Replaces old FR10 products)
BASED ON BS 5400 –PART 9
(In Conformance to) 60 IRHD
Structural movements, due to various forces such as longitudinal, transverse and rotational, can effectively cause problems to structures such as building, bridge, tunnel, etc. One highly effective and efficient methods of dealing with these forces is the use of Elastomeric Bearing Strips. One of the key advantages of these strips is to isolate vibration in the structure; in line with this, it is important to note that natural rubber is very low in deformation over a constant load. This system, in contrast with other potential solutions, is inexpensive, with comparatively minimal effort required when it comes to installation.
The following table gives some information on the selection of FR Series:
Please note that:
- Total Vertical Deflection of a bearing may vary ±15% of the Estimation which is given above and where this parameter is critical to design of the structure, the stiffness of the bearing should be ascertained by tests.
- The Friction Coefficient in calculations is considered to be 0.3. This value can be varied where the seating material of the bearings are some material other than steel or concrete.
- Maximum allowable rotation in the above table is calculated to avoid the uplift even in the minimum permitted vertical load.
- AssaFlex Engineering Department will be pleased to tailor Bearings to meet your needs and requirements in a more cost effective manner, if we have knowledge and specifications of your project.
A MEMBRANE TO USE IN PLACE OF GROUT FOR A VERIETY OF CONDITIONS IN THE CONSTRUCTION OF BUILDINGS.
Design Features
A hardwearing and durable Reinforced Rubber membrane formed from elastomer, fabric and other additives. It is a versatile rubber system with unique flexibility properties that is designed to absorb the movements.
The purpose of the design after years of experience on rubber product is to produce a membrane to replace grout with two fundamental purposes:
Removal of the wet trade. Increase speed of the installation.
FSM- Strip is flexible enough to fill the concrete contour with other qualities where use of grout is required.
Application
Holding Down bolts Machine bedding and base plates Stanchions Cavity filling Etc
FSM-strip replaces the grout
By using FSM- strip, the client saves money and time, allowing one team to carry out the installation in one cycle, therefore increasing productivity.
Life Expectancy
AssaFlex FSM- Strip has very high life expectancy where grout shelf life would not exceed over 3 years. FSM- strip is manufactured in 10mm, 20mm & 50mm thicknesses.
Production
The membrane can be manufacture according to the customers need, either in strip or in square. Where there are certain numbers of holes required, we can form the holes on receiving the relevant sketch.
Benefits
Designed to accept movements Flexible & durable Where there is a need for Immediate high strength High tensile with vibration resistance Moisture resistance Can be used in freezing temperature Speed up the installation process by removing the wet trade hence saving time Economical Easy to use system.
STRIP BEARING
Bearing strips
FR 10 Elastomeric Bearing Strip is a linear membrane produced with the aim of supporting structures from lateral loads. This high quality reinforced elastomeric membrane will resist displacement, loads and rotation.
The purpose of the design is to produce an enduring linear membrane for use in the construction industry wherever there is the need, being in the highways or buildings such as high or low rise structure.
FR 10 strip can be used where there is the need to control movements, allowing tensile forces and horizontal movements to be absorbed. This will improve structural quality and ability to withstand lateral movements.
The membrane is to carry the lateral forces allowing:
Building to escape damage such as cracks.
Highways to withstanding horizontal movements.
Such compositions may be utilized on substrates which are subject to vibration and deflection, and are capable of recovering from deformation resulting from an elongation, change of temperatures. This product is suitable as a crack suppression membranes and floor levelling.
Design Features
The basic composition of the FR 10 strip are elastomer and layers of woven fabric forming a tough and versatile module that can be used in the construction of building and civil engineering projects.
FR10 is manufactured in 1 M length with width of 100mm or 150mm
Thickness
Thickness of the membrane can varies between 5 – 25mm depending on the loads and displacements the membrane is subjected to.
The typical thickness of this membrane is 10mm and can be designed to suit the customer’s requirements.
Benefits
- Designed Flexible & durable Strength Crack Suppression Economical Easy to use system The membrane can be used in any temperature.
- Fixing of the membrane
Building structure:
The membrane is positioned under the beam being concrete or steel. Concrete beam: place inside the bottom shutter where the load is being applied. Steel beam: there should be a gap of 1mm between the membranes with the steel beam.
Highways: In the case of highways the membrane placed between the elements of the structure.
Specifications
AssaFlex RF10 is manufactured to ASTM D/2240, 412, 395 specifications with Ozone resistance on ASTM.D/1171 allowing the membrane to be able to stand elements when used externally such as bridge, etc.
AssaFlex FR10 can be manufactured to any standards requested by the customer.
