Novel barricade rib used for negative bending moment rib

Abstract

The invention relates to the field of building construction, in particular to a novel barricade rib used for a negative bending moment rib, which is basically and technically characterized by consisting of a longitudinal rod, a cross rod, support legs, a hook, a rotary tube and a handle, wherein the longitudinal rod is inserted on the cross rod, the outer side of the longitudinal rod is sleeved with the rotary tube, the rotary tube can rotate freely, both ends of the cross rod are provided with the support legs, and the cross rod is provided with the handle. Compared with the currently adopted barricade rib, the invention effectively prevents the negative bending moment rib from sinking, the barricade rib can be reused, a large number of raw materials can be saved, and in the process of smearing floor concrete, because the top fur of the longitudinal rod limits the smearing elevation of the concrete, the thickness of a steel bar protective layer can be precisely controlled within preset range, the construction quality is ensured, and the concrete is molded at one step. Because secondary smoothing is not needed, a large amount of concrete material and manpower are saved.

Description

Technical field: [0001] The invention relates to the field of floor slab construction in the building main structure construction industry, in particular to a novel horse stool tendon for negative moment tendons. technical background: [0002] During the installation of floor reinforcement and concrete pouring, the negative moment tendons sink due to trampling, which reduces the effective bending section of the floor concrete and greatly reduces the bearing capacity of the floor. In order to avoid this situation, the current practice is to set the horse stool bars made of steel bars under the negative bending moments to support the negative moment bars. [0003] This method has a big disadvantage. After the concrete pouring is completed, the horse stool reinforcement can only be permanently left under the negative moment reinforcement and cannot be reused. Because the setting of horse stool bars is a technical guarantee measure of construction quality, not a design require...

Problems solved by technology

[0003]This method has a big disadvantage. After the concrete is poured, the horse stool bars can only be permanently left under the negative moment bars and cannot be reused

Because the setting of horse stool bars is a technical guarantee measure of construction quality, not a design requirement, so this practice has caused a lot of waste of steel
