Description

Technical Field

[0002] Buildings often deform under the influence of external factors, leading to cracks or even structural damage. Expansion joints are structural joints designed to address this issue. Expansion joints are a collective term for expansion joints, settlement joints, and seismic joints. Many buildings incorporate these three types of joints in a comprehensive manner, a concept known as "three joints in one."

[0003] Currently, some expansion joint structures incorporate damping structures at the bottom of the aluminum alloy center plate to improve the damping effect of the center plate and its superstructure. However, most damping structures in expansion joint structures are currently installed using screws, requiring frequent screw rotation. This installation process is relatively cumbersome and inefficient. Utility Model Content

[0034] A waterstop 26 is provided on the lower inner side of the expansion joint 2; the waterstop 26 can prevent water leakage from the expansion joint 2.

[0035] Working principle:

[0036] During construction, the waterstop 26 is first installed at the bottom of the expansion joint 2. Then, the horizontal plates on both sides of the bottom of the first aluminum alloy base 3 are fixed to the upper side of the floor slab 1 on the same side using the first expansion bolt 23 and the second expansion bolt 24. After the first aluminum alloy bases 3 on both sides are installed, the shock-absorbing mechanism is fixedly installed between the two first aluminum alloy bases 3 at the upper end of the inner side of the expansion joint 2. Then, the second aluminum alloy base 4 is placed on the horizontal plate of the first aluminum alloy base 3 on the same side near the expansion joint 2. After the base 4 is placed, the left and right sides of the aluminum alloy center plate 5 are placed on the horizontal plates at the bottom of the two second aluminum alloy bases 4 respectively, and the two sides of the aluminum alloy center plate 5 are fixedly connected to the two floor slabs 1 respectively by two third expansion bolts 25. Then, the base plate decoration components are constructed in the space between the two second aluminum alloy bases 4 and on the floor slab 1 on the side of the first aluminum alloy base 3 away from the expansion joint 2. Finally, the sealant 22 is applied to the gap between the first aluminum alloy base 3 and the second aluminum alloy base 4 on the same side.

[0037] The specific installation process of the shock absorption mechanism is as follows: First, insert the plug 13 at the left end of the horizontal rod 6 into the slot 15 on the first aluminum alloy base 3 on the left. Then, flip the right end of the horizontal rod 6 from top to bottom until the buckle 14 at the lower right end of the horizontal rod 6 engages with the slot 16 on the first aluminum alloy base 3 on the right. Then, adjust the lifting and lowering of the disc 11 by rotating the nut 10, thereby adjusting the tension of the tension spring 12 until the force of the top plate 9 in all shock absorption mechanisms is consistent, thus ensuring that the shock absorption effect of all shock absorption mechanisms is relatively consistent.

[0038] In summary, in this structure, the horizontal rod 6 can first be inserted into the slot 15 on the first aluminum alloy base 3 on one side via the insertion rod 13 at one end, and then be engaged with the slot 16 on the first aluminum alloy base 3 on the other side via the buckle 14 at the other end, thereby achieving rapid installation and fixing of the shock absorption mechanism, which greatly improves the installation efficiency of the shock absorption mechanism; the structure can adjust the lifting and lowering of the disc 11 by rotating the nut 10, and adjust the tension of the tension spring 12 by adjusting the lifting and lowering of the disc 11, thereby adjusting the shock absorption intensity of the shock absorption mechanism, and thus can precisely adjust the intensity of all shock absorption structures to the set value to ensure the stability of the overall shock absorption effect of the structure.
