Type steel expansion joint
Type steel expansion joint in accordance with the performance and installation methods can be divided into: type GQF-MZL, type GQF-C, type GQF-Z, type GQF-L, type GQF-F.
Product code and representation methods: to GQF-C60, GQF-F80, GQF-MZL480, GQF-C60 (NR), GQF-F80 (CR) of Bridge Expansion Joint
as an example:
|the GQF is the expansion joint device code for traffic industry standards;|
|type code: -MZL modular representation type and straight beam link chain type;|
|(C, Z, F, l, said the shape of profiled steel;|
|numeric representation of displacement of the telescopic device: 0-1200mm;|
|NR and CR are expressed in rubber: NR is a natural rubber, and CR is indicated by the rubber.|
Model of bridge expansion joint device for GQF-MZL, is bridge expansion joint device of the hot rolled the overall shape of the special-shaped steel design, is composed of side beam, beam, beam and the interlock mechanism is composed of Modular Bridge Expansion Joint
device, applicable to 80mm-1200mm expansion amount large and medium-sized span bridge.
Type GQF-C type, GQF-Z type, GQF-L type, GQF-F type telescopic slit apparatus is composed of two side beams (C type, Z type, F type, L type hot-rolled profiled steel) and rubber sealing belt. Applicable to the expansion of the amount of 0~80mm bridge bridge, classified according to the structure are as follows:
|1. the pure rubber expansion device is composed of rubber (including special shaped steel beam height is not larger than 50mm and the sealing rubber belt). It is suitable for the bridge engineering of highway with no more than 60mm.|
|2. Plate expansion body made of rubber, steel or iron sulfide as one. It is used in expansion amount less than 60mm of road and bridge engineering, does not apply to highway and bridge engineering.|
|3. combined type telescopic unit telescopic body by the rubber plate and the steel plate combination. It applies to expansion amount is less than 12mm in road and bridge engineering, does not apply to highway and bridge engineering.|
|4. Modulus telescopic device is made of the overall shape of the special-shaped steel, by the edge of the beam, beam, beam, displacement control system, sealing rubber belt components. Modular bridge expansion device is divided into: type GQF-C bridge expansion device, GQF-MZL type of bridge telescoping device.|
The characteristics: the whole body is good, high compressive and flexural strength, vehicle passed smoothly without jump, the noise is low.
Uses: various bends, the slope, the oblique, the wide bridge. The design of the Modular Expansion Joint displacement quantity can be designed according to the actual needs to be in accordance with a certain number of modules to fight.
Installation notes of expansion joint
|1. telescopic device due to transport length restrictions, can be segmented manufactured, splicing on-site . The expansion device storaged at the site should be placed in parallel, not cross stacking, in order to prevent deformation.|
|2. factory, connecting clamps only convenient transportation and design, the gap is not fixed position. Installation of the expansion device, can be done in the Supervision Engineer Accreditation below.If there are provisions in the design documents, to bridge design documents as the basis.|
|3. Before lifting and positioning of the telescopic device, should be reserved for the concrete in the tank to fight hair and clean it. When installing expansion device along the bridge to the width of a value to deal with that on expansion joint gap, and the top surface elevation and elevation design of anastomosis after pad to wear a balance to the connection of horizontal reinforcing steel bar, telescopic device on the anchor bars and beam embedded bars on both sides of the welded (as far as possible to increase the length of welding and welding point, to extend the service life of the telescopic device), relax the fixture, make it telescopic freely. At this time stretching device has entered the working state.|
|4, after the completion of the above process, installation necessary template. To prevent mortar inflows in the expansion joint, then carefully cleaned with water. Placing greater than C50 concrete in concrete preformed groove . During the pouring of concrete should take necessary measures, the vibration compacting.|
|5 after the initial setting of concrete, pull out the template, timely removal of foreign bodies in the expansion joint and special shaped steel.|
