I Q:Please describe the types of the type steel expansion joint? A:Type steel expansion joint can be divided into the following types according to the performance and installation methods: GQF-C type, GQF-Z type, GQF-L type, GQF-F type.In these types, GQF-MZL type steel expansion joint device is made of hot-rolled overall forming profiled bar design of bridge expansion joint device.The GQF-C type, GQF-Z type, GQF-L type, GQF-F type steel expansion joint apply to the bridge joint which expansion volume is less than 80mm. GQF-MZL type steel expansion device is the type steel expansion joint which is made of edge beam, beam, beam and linkage mechanism.It's suitable the medium and large span bridge which its expansion volume is between 80mm with 1200mm.  II Q:What's the main function of the type steel expansion joint? How to realize the function? A: The function of the type steel expansion joint is to to prevent the housing cracks due to climate change. To realize this function, a gap is reserved at certain distance along the length of the building.The building from the roof, walls, floors and other floors above all the components are disconnected.Because the foundation of the building is affected by the temperature change in the ground, it is not necessary to disconnect.Expansion joint width is generally 2 cm to 3 cm, and there are thermal insulation materials in joint.The distance between the two expansion joints is clearly defined in the specification of the building structure.

Installation and construction method of gyz circular plate type rubber bearing the bridge is the use of pot bearing is a semi closed elastic rubber block of steel in the pelvic cavity, the characteristics of the three stress state of fluid, to achieve the rotation of the upper part of the bridge, while relying on a low coefficient of friction between the stainless steel plate f4 plate and the top plate on the middle plate to achieve horizontal displacement of superstructure the shear bearing can no longer bear completely made of rubber, and the indirect effect on the slip between the steel plate and the bottom basin and f4 stainless steel. From the test data, in the three to rubber compressive elastic modulus constraint state is 50000kgcm2, increased nearly 20 times than the elastic modulus of compression without lateral constraintstherefore, the bearing capacity of the bearing is greatly improved, which solves the limitation of the bearing capacity of the plate type rubber bearing, and can meet the requirements of large supporting reaction force, large horizontal displacement and rotation angle.

Description of lead rubber bearing (Seismic Isolator) The Lead Rubber Bearing (LRB), Vulcanized rubber layers are laminated between steel plates to form a flexible structural support. It is installed as a Damping Equipment under building structures so as to control the tremor of structure against the loads of earthquake. 2. Application of lead rubber bearing Base Isolation System, which is a branch of manual technique to reduce the tremor of structure, is widely applied to the large sized structures such as road bridges, rail bridges and nuclear power station to minimize damages from dynamic loads like earthquake. 3. Special Features of lead rubber bearing (1) Strong Points (2)Property of Lead as a Suitable Material for Earthquake Absorbing Work (3)The Economic Design (4)The More Excellent Safety (5)Easy Installation 4. Function of lead rubber bearing The rubber in the isolator acts as a spring. It is very soft laterally but very stiff vertically. The high vertical stiffness is achieved by having thin layers of rubber reinforced by steel shims. These two characteristics allow the isolator to move laterally with relatively low stiffness yet carry significant axial load due to their high vertical stiffness. The lead core provides damping by deforming plastically when the isolator moves laterally in an earthquake.

1. Mixed rubber and metal is only suitable for waterstop with steel edge. 2. If there are other requirements, inspection items can be appropriately added according to buyer and seller. If evaluating mould test in line with users, its anti-mold property should be equal to or above Grade 2. Sealing mechanism In the embedded rubber water stop belt is characterized by high elastic properties under various loads will produce elastic deformation will occur the volume expansion of the water, so it can play a strong role in sealing, which can prevent the water into the building interior and exterior of the building to prevent the building of water to the outside world, also can play a damping strip the buffer. After pretreatment of galvanized steel inserted into the middle rubber vulcanization forming, strong bonding force between the two, has obvious effect of seepage. In buried steel edged waterstop in the middle rubber body structure deformation by compression, stretching, deformation, and the sealing effect of water; galvanized steel and concrete good adhesion, not easy to fall off and loose, the embedded rubber water stop belt can bear large pulling force and torsion. In the construction, due to the huge vibration force of concrete pouring and not easy to be fixed, will make ordinary rubber sealing belt production

Introduction of Hydrophilic water stop Hydrophilic water stop is made from water-swelling rubber water line to the basis of the ordinary rubber water-stop. The product will swell when contacted with the structures. As a result, the tightness is fastened between the water stop and water-proof performance is improved and the problem of circle seepage which puzzles people in a long time is solved. This series of products have been used widely in some key projects and have gotten excellent results.   Features of Hydrophilic water stop Waterproof wire adopted water-swelling rubber which will be self-swelling when contacted with water. So under the function of waterproof wire , the concrete and water can seal better, and waterproof performance can be more excellent.The sections divided into high-strength area, water-proof area and the installation area can take unequal thickness structures according to the unique function of every area. So each part of the sections can get uniform and reasonable force.Telescopic holes' outer wall is plane; formwork folder system  contact surface is large in construction and difficult to dislocation.Setting hole designed on the installation area is convenient to fix with the nearest steel bar, difficult to move ,  construction easily and install firmly.
