Embodiment 1

[0028] Combine below figure 1 and figure 2 The structural composition of the shear reinforcement of the base plate of the present invention will be described in detail. In this embodiment, the foundation floor 10 is an ultra-large and super-thick floor. According to design requirements, multiple layers of densely distributed reinforcement are required. The reinforcement mainly includes the upper reinforcement 11 of the foundation floor, the lower reinforcement 12 of the foundation floor, and shear reinforcement. Of course, according to the design requirements, part of the base plate 10 is also provided with other structural reinforcements.

[0029] Please refer to figure 1 and figure 2 , a kind of shear reinforcement for the foundation floor, which includes several shear reinforcement units 20 arranged at a certain distance, each shear reinforcement unit 20 includes a bent section 21 and an L-shaped right-angle section 22 bound and overlapped, and the bent section The fr...

Embodiment 2

[0036] Please continue to refer figure 1 and figure 2 , the present invention also provides a construction method for the shear reinforcement of the aforementioned foundation base plate, the construction method comprising:

[0037] According to the design, the shear reinforcement unit 20 is divided into a bending section 21 and an L-shaped right-angle section 22 for processing and transported to the construction site for standby;

[0038] The L-shaped right-angle section 22 is constructed simultaneously with the first skin reinforcement in the lower reinforcement 12 of the foundation base plate, and the two are welded together, and the vertical lengths of the adjacent L-shaped right-angle sections 22 are different during installation;

[0039] Set up a load-bearing support (not shown), complete the binding of other steel bars on the foundation floor and the upper reinforcement 11 of the foundation floor 10, and leave a manhole at the upper reinforcement 11 of the foundation ...

Abstract

The invention relates to shear reinforcement of a foundation base plate and a construction method thereof, and belongs to the technical field of building construction. The shear reinforcement of the foundation base plate and the construction method thereof are used for solving the problem that the construction difficulty of existing oversized and extra-thick base plate shear reinforcement is large. The shear reinforcement comprises a plurality of shear reinforcement units formed by bending segments and L-shaped right-angle segments, wherein the shear reinforcement units are arranged at certainintervals in a bonding and lapping mode, the free ends of the bending segments are fixedly connected to upper reinforcement of the foundation base plate, the free ends of the L-shaped right-angle segments are fixedly connected with lower reinforcement of the foundation base plate, and adjacent connectors are arranged in a staggered joint mode. The construction method comprises the steps that two-segment type segmentation machining of the shear reinforcement is performed, firstly the fixed connection of the lower segment reinforcement and first leather reinforcement in the lower reinforcementof the foundation base plate is completed, then the binding of other leather reinforcement in the lower reinforcement is completed, the binding of the upper reinforcement of the foundation base plateis completed, manholes are reserved, and constructors enter between the upper reinforcement and the lower reinforcement for binding and lapping of the upper segment reinforcement and the lower segmentreinforcement through the manholes.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a shear-resistant steel bar for a foundation floor and a construction method thereof. Background technique [0002] In order to bear the compressive, pulling and shearing loads of the upper structure of super high-rise buildings, the foundation floor has the characteristics of large thickness, many rows of steel bars, large diameter and relatively dense. Due to the above-mentioned reasons, the impact of steel column supports and other embedded pipelines, the installation and construction of the shear reinforcement of the foundation floor has become extremely difficult, or even impossible. [0003] Therefore, how to provide a kind of shear reinforcement for the foundation floor and its construction method that can solve the difficult problem of installation and construction of the shear reinforcement and save the construction period has become a technical...
