Hengshui Haotong Engineering Rubber Co., Ltd. specializes in the production of steel structure anti-seismic spherical steel bearings. Steel structure anti-seismic spherical steel bearings have good reputation and quality. High. Users who have used it all say it is good. Order telephone number for anti-seismic spherical steel bearings for steel structures:
The production of anti-seismic spherical steel bearings for steel structures is based on the Transportation Industry Standard of the People's Republic of China "Technical Conditions for Spherical Bearings (B/- ) and Building Seismic Design Code () Steel Structure Design Code (B), a new type of anti-seismic and vibration-absorbing steel bearing developed through detailed static and dynamic analysis. The anti-seismic and vibration-absorbing bearing has a more reasonable structure, more reliable performance and longer service life.
The anti-seismic spherical steel bearings for steel structures include fixed bearings, one-way and two-way three types and grades. Their horizontal bearing capacity, vertical pull-out force and overall strength of the bearing are all higher than ordinary bearings. substantial improvement. This series of supports uses elastic damping elements. When the horizontal force reaches a certain level, the damping spring begins to elastically deform to achieve a buffering effect. When the structure turns a corner, the ball core rotates and releases the torque generated by the upper structure. During an earthquake, rigid anti-seismic measures and flexible vibration-absorbing measures work at the same time to withstand the huge seismic input energy. This can not only ensure the reasonable relative displacement of the upper and lower structures of the bridge, reduce the amplification factor of the seismic force, but also maintain the unity of the structure. . The bearing can withstand high-intensity earthquakes and has good seismic resistance and vibration reduction effect on engineering structures in high-intensity earthquake areas, especially in direct earthquake areas.
Installation method of anti-seismic spherical steel bearings for steel structures
High-strength bolts are used to connect the bearings to the upper structure. Welding can also be used to connect the bearings to the lower structure. Welding is used, and high-strength bolted connections can also be made under special circumstances. Notes:
Mesh plus steel structure supports are assembled by the manufacturer and shipped as a whole. Before installation, a comprehensive inspection should be carried out to see if any parts are missing or damaged. Check whether the screw hole spacing and hole diameter of the upper structure and the upper seat plate of the support match, whether the selected model is correct, whether the rotation angle and displacement in all directions are consistent with the design, and the inspection shall be based on the design drawings.
B. When installing the support, cross center lines should be marked on the four sides of the upper and lower bottom plates to facilitate installation and alignment. During installation, the upper seat plate of the support and the steel plate of the superstructure should be connected with high-strength bolts, and larger than Wrench manual tightening. Special circumstances require special wrenches for installation and manual tightening.
After the position of the support is determined, it can be fixed up and down. The connection between the support and the upper and lower structures can be connected with high-strength bolts or welded, or both methods can be used at the same time. When welding is used, embedded steel plates must be installed, and anchor bars should be welded on the side in contact with the concrete to achieve a certain strength and stiffness. The bearing manufacturer can produce the embedded parts together. The embedded steel plate should have an appropriate number of evenly distributed vent holes of small diameter. During welding, drag welding should not be continued, but intermittent welding should be used to gradually fill up the welds to avoid deformation of the support or embedded steel plate caused by excessive local temperature during welding.
After installation or welding is completed, remove the upper and lower connecting plates.
Maintenance of anti-seismic spherical steel bearings for steel structures
The bearings should be maintained regularly every year.
. Check whether the support connection weld is loose or cut, and whether the support seal is damaged.
Check whether the relative displacement of the supports is uniform, and check and record the displacement of the supports one by one.
Loosen the nut once, clean and oil it to prevent the nut from rusting, and then tighten it.
The oil storage cavity on the bearing should be kept full of lubricating oil without overflowing (relative to the steel ball bearing).
. Check whether the anti-corrosion coating on the surface is damaged. If there is any damage, repair it in time.
