Buckling concrete split head for supporting upper and lower layers of steel bars

Abstract

A buckling concrete split head for supporting upper and lower layers of steel bars is characterized in that ']' shaped metal bars are arranged on two sides of the inside of a concrete split head body to enhance the strength of the concrete split head body; an upper-through and gradually-opening notch and L-shaped steps are formed in the upper end of the concrete split head body and used for crossing the upper steel bars in an avoidance manner and realizing supporting positioning, a lower-through and gradually-opening notch and acute angles or U-shaped slots are formed in the lower end of the concrete split head body and used for crossing the lower steel bars in an avoidance manner and realizing supporting positioning, so that space between the upper and the lower steel bars is kept, the center of the concrete split head body can be supported for stressing, and the stability is improved; buckling metal bars are arranged on two walls of the upper ends of the L-shaped steps, and buckle the upper steel bars and further stabilize the concrete split head body, so that the concrete split head body cannot be moved or knocked down during construction treading; upper and lower end surfaces of the concrete split head body are scale heights for indicating the thicknesses of protective layers of steel bars; and rough concave and convex surfaces which are convenient to tightly combine concrete are arranged on the surface of the concrete split head body. The buckling concrete split head is used for realizing once supporting positioning of double layers of bidirectional steel bars and is convenient to mount, and the work efficiency and the project quality are improved.

Description

technical field [0001] The invention relates to a structural member used in a building, in particular to a locator used for supporting the upper and lower layers of steel bars during the construction process of a reinforced concrete structural slab encountering double-layer two-way steel bars, so as to prevent it from being moved and knocked down, and has an indication The elevation of the thickness of the upper and lower reinforced concrete protective layers can effectively maintain the lockable concrete horse bench with the spacing between the upper and lower steel bars. Background technique [0002] During the construction of the reinforced concrete structural slab, in order to ensure the quality requirements of the reinforced concrete structural slab, the upper and lower steel bars need to be supported and positioned to maintain the proper spacing between the upper and lower steel bars to improve the prestressing of the reinforced concrete structural slab. The existing m...

But it still has the following deficiencies: when the upper end of the concrete stool body supports the upper layer of steel bars, the center point of the upper end of the concrete stool body is not supported to bear the force, the stability is not ideal enough, and the steel bars are produced when the steel bars are small and trampled during the construction process. The rebound force increased, and some concrete stools were knocked down

In addition: Comrade Yan Xing once disclosed an invention patent "Horse Stool for Building Floors" Patent No.: 201110307260.X, its technical characteristics: the upper part of the column is provided with an upper steel reinforcement groove that cooperates with the interlaced upper upper reinforcement of the floor, and the column The lower part of the body is provided with a fixing groove for the lower layer of steel bars that is interlaced with the lower layer of the floor slab. Although it overcomes the disadvantage of the central point of the upper end of the concrete pier not being able to support the poor stability of the force, it is bulky and heavy. The height should not be less than 25mm. If metal bars are not added to the concrete pier body, it is easy to break the foot. During the production process, the upper and lower cross grooves are not easy to demould, and the production efficiency is low, so it cannot be mass-produced

The above-mentioned steel bar stools and concrete product horse stools have not solved the support positioning of the lower steel bars, and the upper and lower double-layer two-way steel bars must be supported separately. Therefore, in order to make up for the above-mentioned shortcomings, I have invented a buckle for supporting the upper and lower steel bars. Concrete horse stool
