Description

Concrete stirrup

Technical Field

The utility model belongs to the technical field of auxiliary building construction devices, and particularly relates to a concrete stirrup.

Background

The floor thickness that easily appears in the construction of reinforced concrete floor does not satisfy standard requirement, and the double-deck two-way reinforcing bar interval is not enough, and the upper and lower surface of floor and the protective layer between the double-deck two-way reinforcing bar are not enough, floor reinforcing bar cushion is not enough etc. quality problems.

At present, the reinforced concrete floor slab adopts the traditional construction process:

1. the protective layer of the lower reinforcing steel bars of the double-layer bidirectional reinforcing steel bars is mainly controlled by a concrete cushion block, the lowered reinforcing steel bars are deflected randomly due to the absence of a positioning support, and most of the lower reinforcing steel bars of the floor slab have no protective layer after the reinforcing steel bars are bound, so that the phenomenon of exposed reinforcing steel bars occurs after the floor slab is poured;

2. in traditional construction process, to the best finished product reinforcing bar stirrup that is of two-layer reinforcing bar interval control about the two-layer two-way floor reinforcing bar, nevertheless because finished product reinforcing bar stirrup is directly to be located on the template, can have phenomenons such as exposed muscle, return rust and construction cost higher, it is very unfavorable to later stage dimension guarantor.

3. Most of the existing floor thickness controllers are trapezoidal block-shaped bodies made of cement, a groove for placing bottom-layer steel bars is formed at the bottom of each floor thickness controller, upper-layer steel bars are randomly placed on the cement blocks, and the installation precision is low; the error of concrete pouring is too large by taking the distance of the concrete pouring which is submerged by the reinforcing mesh on the upper layer as a criterion.
