Concrete partition combination tool

Abstract

The invention discloses a concrete partition combination tool, which comprises a rotatable baffle, a latch and a positioning bottom plate; the rotatable baffle is divided into a first rotatable baffle and a second rotatable baffle, and the rotatable baffle consists of The main shaft is made, the bottom of the main shaft is welded with a section of round steel as the positioning shaft, the top of the main shaft is welded vertically with a connecting pipe, the side of the main shaft of the first rotatable baffle is welded with a certain distance between two first wing plates, and the second rotatable The two sides of the main shaft of the baffle plate are welded symmetrically to the second wing plate; the positioning base plate is provided with a positioning hole suitable for the positioning shaft, the second rotatable baffle plate is arranged in the middle of the positioning base plate, and the two ends of the positioning base plate are provided with a second wing plate. A rotatable baffle, the wing plates of the two first rotatable baffles are arranged oppositely; the bolt is a round steel, and the connecting pipe running through the top of the rotatable baffle restricts its free rotation. The combination tool is flexible in operation, convenient and fast in installation and disassembly, saves time and effort, and speeds up the construction progress on the premise of ensuring the construction quality.

Description

technical field [0001] The invention relates to a combined tool used in building structure construction, in particular to a combined tool for partitioning concrete with different strength levels used in the pouring of structural beam-column joints. Background technique [0002] With the rapid development of high-rise building structures, in the process of pouring concrete of different strength grades in the beam-column joint area of ​​high-rise buildings, in order to achieve the seismic design principles and structural design requirements of "strong columns and weak beams, strong shear and weak bending", column concrete The strength grade of the beam-slab concrete is higher than that of the beam-slab concrete. At this time, the concrete in the beam-column joint area must be specially treated to make the concrete strength grade of the joint area the same as that of the column. [0003] At present, the common practice is to use half the distance from the height of the column s...

Problems solved by technology

[0004] However, the above-mentioned method not only takes a long time to bind the dense-mesh steel wire mesh before each pouring, but also cannot seal the gap between the outer steel bars and the beam side formwork; The pressure of the concrete, coupled with the vibration of the vibrating rod, often causes the steel wire mesh to break, so that the beam concrete can only be poured with high-grade concrete, resulting in a great waste of materials
