Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to figure 1 , the present invention provides a punching-resisting reinforcement structure and a construction method thereof. By placing the end plate at the bottom of the high-strength reinforcement on the concrete pad below the lower reinforcement, the high-strength reinforcement is vertically arranged and passed through the upper reinforcement and the lower reinforcement , so that the end plate at the top of the high-strength steel bar is located at the upper steel bar, and then poured to form the raft foundation, the end plate and high-strength steel bars are buried in the raft foundation to provide punching resistance to the raft foundation, which solves the problem of raft foundation The problem of insufficient punching resistance of concrete is to improve the punching resistance of the raft foundation, and the installation is...

Abstract

The invention relates to an anti-punching reinforcing steel bar structure and a construction method thereof. The anti-punching reinforcing steel bar structure is used for penetrating through upper-layer reinforcing steel bars and lower-layer reinforcing steel bars of a raft foundation, and the anti-punching reinforcing steel bar structure comprises high tensile reinforcing steel bars and end plates fixed to the two ends of the high tensile reinforcing steel bars. According to the anti-punching reinforcing steel bar structure, the problem that the anti-punching capacity of raft foundation concrete is insufficient is effectively solved, the anti-punching capacity of the raft foundation is improved, installation is rapid, the construction efficiency is improved, and the construction quality is guaranteed.

Description

technical field [0001] The invention relates to the field of construction, in particular to a punching-shear resistant steel bar structure and a construction method thereof. Background technique [0002] As an important foundation of super high-rise buildings, rafts have the advantages of high rigidity, uniform settlement, high bearing capacity, and good seismic performance. The main factor controlling the thickness of rafts is the punching resistance of rafts. [0003] The rafts of super high-rise buildings are subjected to huge stress and the number of raft reinforcements is large. However, the ends of the commonly used punching shear steel bars cannot be directly anchored to the raft reinforcements. Therefore, in actual engineering, only the raft concrete For punching shear resistance, the most commonly used method at present is to increase the punching shear resistance of the raft by locally increasing the thickness of the raft. However, this method has problems such as ...
