Structure and method utilizing anti-floating anchor rods to support underground raft plates

Abstract

The invention discloses a structure utilizing anti-floating anchor rods to support underground raft plates, which comprises an upper-row raft plate steel bar frame, a lower-row raft plate steel bar frame paved on the ground and a support structure supporting the upper-row raft plate steel bar frame. The structure utilizing the anti-floating anchor rods to support the underground raft plates is characterized in that the support structure comprises a plurality of groups of anti-floating anchor rods and a plurality of support rods, the plurality of groups of anti-floating anchor rods are embedded in the ground at fixed intervals, the tops of the anti-floating anchor rods are in fastening connection with the support rods, and the upper-row raft plate steel bar frame is arranged on the support rods. The structure and a method which utilize the anti-floating anchor rods to support the underground raft plates are adopted, the fact that anchoring portions of the anti-floating anchor rods of basement raft plates replace horse stool ribs is achieved, and the structure and the method have the advantages of being convenient and fast to construct, safe, reliable, green, energy-saving and low in construction cost.

Description

technical field [0001] The invention relates to a supporting structure and a method, in particular to a structure and a method for supporting an underground raft by using an anti-floating anchor rod. Background technique [0002] refer to image 3 As shown, the structure of the underground raft mainly includes an upper row of raft reinforcement frames 1 and a lower row of raft reinforcement frames 2. When erecting, the upper row of raft reinforcement frames 1 is supported by horse stool bars 6, and the distance between them is maintained. After the erection of the upper row of raft reinforcement frames 1 and the lower row of raft reinforcement frames 2 is completed, concrete is poured to form a complete underground raft structure. When the comprehensive load generated by the building's own weight and other external factors is not enough to balance the buoyancy generated by the groundwater, a certain vertical external force must be applied to the foundation floor to balance t...

AI Technical Summary

Problems solved by technology

[0003] However, in the above-mentioned construction process, the horse stool bars 6 that support the upper row of raft reinforcement frames 1 are made of large-scale steel bars, and the spacing is small, so more steel bars need to be used for production, and the material consumption is large. A lot of manual processing, and there are problems such as unstable steel support and easy bending deformation, inconvenient use during construction, and difficult adjustment, so there is indeed a need for further improvement
