A building construction expansion joint structure

Abstract

The present invention provides an expansion joint structure for building construction, which includes an expansion joint structure body, the expansion joint structure body includes a wall, and a support frame is arranged on the wall body, and the support frame includes a support frame 1 and a support frame 2, One side of the support frame 1 and the support frame 2 are all welded with reinforcing ribs, one side of the reinforcing ribs is welded with a connecting seat, the reinforcing ribs are provided with threaded holes, and the inside of the threaded holes is installed There are fastening bolts, grooves are provided on the first support frame and the second support frame, a support rod is welded on the inner wall of the groove, and a clamping ball is welded on one end of the support rod. The structure is fixed by a shock-absorbing spring at one end of the connecting plate, and the shock-absorbing spring is used to fix the connecting plates while effectively weakening the vibration force generated, effectively avoiding damage caused by vibration, and connecting the connecting plates Fixed, effectively avoiding the impact caused by separation while moving, with multiple functions.

Description

technical field [0001] The invention relates to the field of expansion joint structure equipment, in particular to a building construction expansion joint structure. Background technique [0002] Housing construction expansion joints are expansion joints, which refer to a structural joint set at an appropriate part along the construction joint direction of a building or structure in order to prevent cracks or damage to the structure due to climate temperature changes (thermal expansion, cold contraction). . The expansion joint is to divide the building components above the foundation, such as walls, floors, and roofs (except wooden roofs), into two independent parts, so that buildings or structures can be horizontally expanded along the long direction. The existing building construction expansion joints mainly include Building expansion joints formed by adjacent beams and slabs. However, the impermeability of these expansion joints is not good enough, and the waterstop is ...

AI Technical Summary

Problems solved by technology

However, the impermeability of these expansion joints is not good enough, and the waterstop is easy to age. If the waterstop is not replaced after aging, the sewage will enter the expansion joint and extend into the building structure, reducing the service life of the building. Replace the waterstop It will increase the cost and waste manpower and material resources. The expansion steel of these house construction expansion joints will generate a lot of vibration and noise when there are vehicles driving nearby, the safety performance is not good enough, and the stability of the sealing cover is low. Therefore, , we invented a housing construction expansion joint structure to meet the needs of society
