Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an anti-seismic support. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. It includes foundation engineering construction, main structure construction, roof engineering construction, decoration engineering construction, etc. The place where the construction work is done is called "construction site" or "construction site", also called construction site.

[0003] In the process of construction engineering, in order to increase the stability of the building, a support is often used to support the building assembly. For example, there is a seismic support for buildings with a Chinese patent publication number of CN218509161U. By setting a first spring and a shock-absorbing damper, when the building assembly vibrates, the placement plate slides in the limit groove, and the first spring is pressed downward to cooperate with the shock-absorbing damper to play a role of shock absorption and buffering to prevent the building assembly from tilting. The first support rod and the second support rod can play a supporting role; by setting a second spring, the placement plate presses the pressure rod downward, and the pressure rod slides and squeezes the second spring to play a second shock-absorbing protection role, further improving the shock-absorbing protection ability of the building; by setting a connecting seat and a fixing seat to fit together, when the building assembly is installed, the screw rod is rotated forward. When the screw rod rotates, the first connecting member pushes the card plate through the connecting rod, so that the card plate is inserted into the card slot to fix the building assembly, and the stability is high; by setting a leveling rod, it is convenient to level the building to prevent it from tilting.

[0004] However, the device is only set to provide vertical shock absorption, with the lowest shock absorption limit and insufficient practicality. Utility Model Content
