Description

Technical Field

[0001] This invention belongs to the field of seismic composite beams, specifically relating to modular seismic composite beams for public buildings and their application methods. Background Technology

[0002] The Earth's interior is divided into three layers: the crust, the mantle, and the core. Buildings are attached to the outermost crust. Earthquake damage is caused by the strong shaking of the ground caused by seismic waves, resulting in the collapse of buildings and other structures. Seismic waves are classified into three types according to their propagation mode: P-waves, S-waves, and surface waves. P-waves are propagating waves that travel at about 6 kilometers per second in the crust and reach the epicenter first, causing the ground to shake vertically, but their destructive power is not strong. S-waves are shear waves that travel at about 4 kilometers per second in the crust and reach the epicenter second, causing the ground to sway back and forth and side to side, and their destructive power is relatively strong. Surface waves are mixed waves generated by the encounter of P-waves and S-waves on the ground. They travel at about 3 kilometers per second and have a larger wavelength and amplitude, making them the main factor causing damage to buildings.

[0003] The existing seismic composite beams are inconvenient for workers to install, and damage between the square columns can cause them to detach from the main structure, leading to the collapse of the secondary supports near the main beam and causing safety accidents. Summary of the Invention

[0012] Preferably, the surfaces of the crossbeam and the support column are provided with support grooves, and one side of the support sleeve and the fixed sleeve is provided with a U-shaped clamping plate. The U-shaped clamping plate is engaged with the support groove. The fixed sleeve is composed of two U-shaped fixed frames that rotate and cooperate with each other.

[0013] The method for using modular seismic-resistant composite beams in public buildings includes the following steps:

[0014] S1. Place the crossbeam into the placement slot and move the L-shaped sliding plate upward. The L-shaped sliding plate passes through the adapter slot of the crossbeam and into the slot. When the L-shaped sliding plate moves into the slot and contacts the push rod, it can push the push rod upward. When the push rod moves to the position of the through slot, the moving plate moves under the action of the spring. The moving plate moves and drives the clamping plate to move. When the clamping plate moves into the fixed slot, the L-shaped sliding plate can be fixed.

[0015] S2. When the crossbeam is under stress, the force on the crossbeam will drive the spring four to move inside the telescopic cylinder through the fixed column. Under the action of the spring three and the push plate, the pressure on the crossbeam can be relieved.

[0016] S3. By setting a U-shaped clamp, the support sleeve and the fixed sleeve are fixed inside the support groove on the surface of the support column and the beam through the U-shaped clamp, so that the support sleeve and the fixed sleeve can be fixedly installed.

[0017] S4. By setting a connecting rod, the connecting rod is inserted into the inside of the connecting groove. Under the action of the spring pin, the connecting rod is fixed, thus completing the installation of the support sleeve and the fixed sleeve.

[0018] S5. Move the L-shaped sliding plate upward. The L-shaped sliding plate passes through the adapter groove of the crossbeam into the inside of the slot. The L-shaped sliding plate moves into the inside of the slot and contacts the push rod.

[0019] S6. When the crossbeam is under stress, the load on the crossbeam moves inside the telescopic cylinder through the fixed column and the spring four. Under the action of the spring three and the push plate, the pressure on the crossbeam is relieved.

[0020] S7. By setting limit block one, the push rod is limited to maintain stability during operation. By setting limit block two, the card plate is limited to maintain stability during operation.

[0021] S8. By setting a U-shaped clamp, the support sleeve and the fixed sleeve are fixed inside the support groove on the surface of the support column and the beam through the U-shaped clamp, so that the support sleeve and the fixed sleeve can be fixedly installed.

[0022] S9. By setting a connecting rod, the connecting rod is inserted into the inside of the connecting groove. Under the action of the spring pin, the connecting rod is fixed, thus completing the installation of the support sleeve and the fixed sleeve.

[0023] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0024] By setting an L-shaped sliding plate, the crossbeam can be engaged through the adapter groove, thereby fixing the crossbeam. The moving plate and push rod can move the locking plate, which can be fixed to the L-shaped sliding plate through the fixing groove, thus completing the fixation of the crossbeam, increasing the fixing effect and improving the stability of the fixation. This structure is simple and convenient for workers to install or disassemble, making it easy for workers to operate. Attached Figure Description

[0039] One application of this embodiment is as follows: In use, the crossbeam 10 is placed inside the placement groove 7, and the operator moves the L-shaped sliding plate 3 upward. The L-shaped sliding plate 3 passes through the adapter groove of the crossbeam 10 and into the slot 20. When the L-shaped sliding plate 3 moves into the slot 20 and contacts the push rod 18, it pushes the push rod 18 upward. When the push rod 18 moves to the position of the through groove 23, the moving plate 9 moves under the action of the spring 22. The movement of the moving plate 9 drives the locking plate 19 to move. When the locking plate 19 moves into the fixing groove 6, the L-shaped sliding plate 3 is fixed. When the crossbeam 10 is under force, the force on the crossbeam 10... The fixed column 12 drives the spring 27 to move inside the telescopic cylinder 13. Under the action of the spring 26 and the push plate 28, the pressure on the crossbeam 10 can be relieved. By setting the U-shaped clamping plate 31, the support sleeve 14 and the fixed sleeve 11 can be fixed inside the support groove 30 on the surface of the support column 1 and the crossbeam 10, thereby fixing the support sleeve 14 and the fixed sleeve 11.
