Fixing device for lower pre-embedded steel plate of shock insulation support seat, and construction method thereof

Abstract

The invention provides a fixing device for a lower pre-embedded steel plate of a shock insulation support seat, and a construction method thereof. The fixing device for the lower pre-embedded steel plate of the shock insulation support seat comprises an anchoring frame base arranged at the junction of a first-section pouring-tamping layer and a second-section pouring-tamping layer of a lower buttress, wherein a plurality of anchoring frame anchor bars stretching into the first-section pouring-tamping layer are fixed to the bottom surface of the anchoring frame base; a plurality of anchoring columns are fixed to the top surface of the anchoring frame base; an end plate is fixed to the top end of each anchoring column; a bolt is in threaded connection to each end plate; and the top end of each screw rod is fixed to the bottom surface of the lower pre-embedded steel plate. The problem of unqualified installation quality of a shock insulation support seat due to that a deflection of the position of a lower pre-embedded steel plate is easily caused in a process of pouring tamping a lower buttress in the prior art, is solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a fixing device for a pre-embedded steel plate under a shock-isolation support and a construction method thereof. Background technique [0002] In order to enhance the seismic performance of buildings, buildings usually need to add an isolation layer between the superstructure and the foundation to become an isolation building, and most of the isolation layers use isolation rubber bearings. The principle of building isolation is to use the horizontal deformation of the isolation support to extend the structural period and reduce the transmission of seismic energy to the upper structure. Therefore, during the construction of earthquake-isolated buildings, the earthquake-isolation layer needs to be installed with earthquake-isolation bearings. [0003] The shock-isolation support is composed of a support body and upper and lower connecting plates. The upper and lowe...

Problems solved by technology

[0006] Aiming at the above-mentioned problems in the prior art, the present invention provides a fixing device for the pre-embedded steel plate under the shock-isolation bearing, which solves the problem that the position of the lower pre-embedded steel plate easily occurs during the process of pouring and tamping the lower pier in the prior art. Misalignment leads to unqualified installation quality of seismic isolation bearings
