Description

Technical Field

[0001] The utility model relates to the technical field of concrete pouring, in particular to a concrete intercepting device with different strength grades at a beam-column node. Background Art

[0002] In recent years, with the rapid compression of the construction industry, the competition has become increasingly fierce. If you want to occupy a place in the construction industry, you must have your own characteristics and competitiveness. Under the premise of ensuring the quality of the project, improving work efficiency is also a sharp sword in the current corporate competition. Therefore, we engineers need to constantly seek innovation and find faster and better construction methods.

[0003] Publication No. CN217420496U describes a device for intercepting high-strength concrete in a beam, comprising a beam main bar, stirrups, screws and an interception frame. The beam main bars are arranged in a number and are distributed in parallel with each other. The beam main bars are divided into two rows and distributed in a rectangular array. The stirrups are arranged in a number and are evenly distributed at equal distances along the length direction of the beam main bars and are mounted on the outside of the beam main bars. The screws are installed at the bottom of the beam main bars at the bottom. The interception frame is installed between the beam main bars along an inclined direction of 45°. The utility model relates to the field of building construction technology. The device for intercepting high-strength concrete in a beam is provided with an interception frame, and uses steel bars that are easily obtained at the construction site, stirrups and screws as a supporting structure to carry out the laying operation of the interception frame. The device is simple to manufacture, easy to install and disassemble, and improves work efficiency. It has strong applicability and can be widely used in complex beam-column node areas. However, the prior art still has defects:

[0004] 1. The interception device used in the prior art uses an interception frame made of steel bars to intercept high and low strength concrete during beam casting. However, the lengths of concrete casting at the nodes are different, so the interception frame needs to be adjusted, which is troublesome to use.

[0005] 2. After the interception device used in the prior art intercepts the concrete at the node, the interception frame needs to be dismantled before pouring the subsequent sections. The interception device cannot be removed quickly, and it may be impossible to form continuous pouring of other sections after the initial setting of the concrete, or the degree of fluidity loss during the initial setting of the concrete may be insufficient, resulting in mixing of high-strength and low-strength concrete.
