Recyclable inner-bracing sleeve

Abstract

The invention discloses a recyclable inner-bracing sleeve. The recyclable inner-bracing sleeve comprises inner-bracing sleeve chock plugs and an inner-bracing sleeve main part; the two inner-bracing sleeve chock plugs are respectively connected to two ends of the inner-bracing sleeve main part; the inner-bracing sleeve main part has a large end and a small end; each inner-bracing sleeve chock plug also has a large end and a small end; tables are respectively arranged in two tips of the inner-bracing sleeve main part; the inner-bracing sleeve main part is connected with the inner-bracing sleeve chock plug through the tables; the tables are connected with connecting parts of the inner-bracing sleeve chock plugs; each inner-bracing sleeve chock plug is provided with a key hole; each key hole is T-shaped; each inner-bracing sleeve chock plug can be disassembled from the inner-bracing sleeve main part by twisting at an angle of 90 degrees through the corresponding key hole; and during pouring of a concrete wall, the width of the wall is controlled, the thickness of a protecting layer of a reinforcement in concrete is controlled, the recyclable inner-bracing sleeve has functions of an inner-bracing strip, an opposite-pulling screw can be isolated from the concrete by the recyclable inner-bracing sleeve in formwork engineering, and the recyclable inner-bracing sleeve has functions of a sleeve.

Description

technical field [0001] The invention relates to the technical field of concrete wall pouring, in particular to a recyclable inner support sleeve. Background technique [0002] Any concrete wall is poured with internal stays that control the width of the wall and the thickness of the base cover that controls the reinforcement in the concrete. The purpose is to effectively control the width of the concrete wall during the pouring process, and control the thickness of the basic protective layer of the steel bar in the wall within an effective allowable range. Any formwork support system will use the pull screw in the formwork support process, and the casing will be used when using the pull screw. It is hoped that the concrete and the screw will be isolated during the concrete pouring process, and the screw can be removed after the pouring is completed. The method and device for controlling the width of the wall and the thickness of the protective layer of steel bars usually us...

AI Technical Summary

Problems solved by technology

The method and device for controlling the width of the wall and the thickness of the protective layer of steel bars usually use: cement inner stays; but there are problems such as easy damage and difficult fixation during the formwork support process

[0003] The casing used when using the pull screw in the formwork support is usually: ordinary PVC pipe and special screw casing, etc.; but there are problems such as the casing cannot be taken out after the concrete pouring is completed, waste of materials, and cannot be reused.
