Raft plate steel bar support device

Abstract

The invention provides a raft plate steel bar support device. The raft plate steel bar support device comprises an upper steel bar net, a lower steel bar net, a supporting mechanism, a fixing mechanism and a connecting mechanism; the supporting mechanism is installed between the upper steel bar net and the lower steel bar net and comprises fixing sleeves, supporting rods, balls, connecting rods and clamping grooves; the side walls of the supporting rods abut against the side wall of the upper steel bar net and the side wall of the lower steel bar net; the multiple fixing sleeves are connected into the supporting rods in a sliding manner; one end of each fixing sleeve rolls and is clamped to the corresponding ball; one end of each ball is fixedly connected with the corresponding connecting rod with the L-shaped side wall; the clamping grooves are formed in the side walls of the connecting rods, and the connecting rods abut against the side wall of the upper steel bar net and the side wall of the lower steel bar net; and the fixing mechanism is clamped to the lower steel bar net and abuts against the side walls of the supporting rods. The raft plate steel bar support device has the beneficial effects of being convenient to install and high in stability.

Description

technical field [0001] The invention relates to the technical field of raft steel bar support, in particular to a raft steel bar support device. Background technique [0002] Raft slab, a concrete slab in foundation engineering, under the slab is the foundation, and above the slab there are columns, walls, etc. Because it floats on the soil like a raft, it is vividly called a raft. The foundation type of the building is closely related to the type of foundation soil and the distribution of soil layers. [0003] When binding raft steel bars, it is necessary to lap a layer of steel mesh on the bottom surface, and then lap another layer of steel mesh on top of it. Horse stool steel bars are usually used for connection and support between the two layers of steel mesh, but during use , Workers often use welding to fix, the operation time is long, the labor load is heavy, and during the construction process, the installation position of the horse stool steel bar and the upper an...

Problems solved by technology

[0003] When binding raft steel bars, it is necessary to lap a layer of steel mesh on the bottom surface, and then lap another layer of steel mesh on top of it. Horse stool steel bars are usually used for connection and support between the two layers of steel mesh, but during use , workers often use welding to fix, which takes a long time to operate and requires a lot of labor. In addition, during the construction process, the installation position of the horse stool steel bar and the upper and lower layer steel bars is prone to deviation, which reduces the stability and firmness of the upper and lower layer steel mesh.
