Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a self-locking reinforcement device for a fully enclosed small space. Background Technology

[0002] Aluminum alloy formwork is widely used in the construction industry. When aluminum alloy formwork is used to create a fully enclosed, narrow space, it is impossible for people to enter and operate, and it is impossible to fix the formwork. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a self-locking reinforcement device for a fully enclosed small space, which solves the technical problem that it is impossible for manual entry to operate and fix the template in a fully enclosed and narrow space.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a self-locking reinforcement device for a fully enclosed small space, including a self-locking back rib and a reinforcement screw. The self-locking back rib includes an upper reinforcement component, an upper connecting plate connected to the upper reinforcement component, a lower reinforcement component located below the upper reinforcement component, a lower connecting plate connected to the lower reinforcement component, and a tie rod nut located between the upper and lower reinforcement components. The tie rod nut cooperates with the reinforcement screw. The principle of this utility model is as follows: First, the aluminum template and the self-locking reinforcement back rib are installed; then, the aluminum templates are spliced ​​together to form a fully enclosed small space; the reinforcement screw is inserted from the outside to lock the self-locking reinforcement back rib, and cooperates with the outer reinforcement back rib to reinforce the small space so that the self-locking reinforcement back rib presses down on the aluminum template to achieve the purpose of fixation.

[0005] As an improvement, the upper and lower reinforcement components have the same structure and are both trapezoidal tubular fittings.

[0006] As an improvement, a support pipe with a welded connection is also provided between the upper and lower reinforcement components.

[0007] As an improvement, one side of the upper connecting plate is welded to the upper reinforcement, and the other side extends out. The extended side is provided with an upper connecting hole, and an upper nut is welded to the upper connecting hole. One side of the lower connecting plate is welded to the lower reinforcement, and the other side extends out. The extended side is provided with a lower connecting hole, and a lower nut is welded to the lower connecting hole.

[0008] The beneficial effects of this utility model compared with the prior art are:

[0009] The fully enclosed, confined space is equipped with a self-locking reinforcement device that works in conjunction with an externally inserted self-locking screw. This allows workers to operate the device normally from the outside, enabling on-site personnel to quickly assemble and disassemble it. It is also reusable. Attached Figure Description

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1 As shown, a self-locking reinforcement device for a fully enclosed small space is disclosed. The fully enclosed small space is composed of multiple aluminum templates facing different directions, each aluminum template including four circumferentially distributed first aluminum templates 1 and four second aluminum templates 2 respectively disposed between adjacent first aluminum templates 1. The first aluminum templates 1 and second aluminum templates 2 form a square fully enclosed small space. Figure 4 As shown, the first aluminum template 1 is trapezoidal, and includes a first panel 11 and first connecting plates 12 disposed on both sides of the first panel 11; Figure 5 As shown, the second aluminum template 2 includes a triangular second panel 21 and second connecting plates 22 disposed on both sides of the second panel 21. The first connecting plate 12 abuts against and connects with the second connecting plate 22. The first panel 11 and the second panel 21 are spliced ​​to form a flat surface. The inner side of the first aluminum template 1 is provided with a first reinforcing plate, and the inner side of the second aluminum template 2 is provided with a second reinforcing plate. Figure 2 , 3As shown, the self-locking reinforcement device includes a reinforcing self-locking back rib 4 and a tie rod nut 45 disposed on the back of the first aluminum template 1 within the fully enclosed small space. The reinforcing self-locking back rib 4 includes an upper reinforcement member 41, an upper connecting plate 43 connected to the upper reinforcement member 41, a lower reinforcement member 42 disposed below the upper reinforcement member 41, a lower connecting plate 44 connected to the lower reinforcement member 42, and a tie rod nut 45 disposed between the upper reinforcement member 41 and the lower reinforcement member 42. The tie rod nut 45 cooperates with a reinforcing screw 3. A through hole is provided on the aluminum template corresponding to the tie rod nut 45. One end of the reinforcing screw 3 passes through the through hole and is threadedly connected to the tie rod nut 45. A support tube 46 is also provided between the upper reinforcement member 41 and the lower reinforcement member 42. The support tube 46 is located at... The tie rod nut 45 on both sides makes the upper reinforcement 41 and the lower reinforcement 42 form a stable whole; the upper connecting plate 43 is welded to the upper reinforcement 41 on one side and extends out on the other side. The extended side is provided with an upper connecting hole, and an upper nut is welded at the upper connecting hole. The lower connecting plate 44 is welded to the lower reinforcement 42 on one side and extends out on the other side. The extended side is provided with a lower connecting hole, and a lower nut is welded at the lower connecting hole. The upper connecting plate 43 and the lower connecting plate 44 are fixedly connected to the first reinforcing plate by bolts and nuts respectively; the upper reinforcement 41 and the lower reinforcement 42 have the same structure and are both trapezoidal tubes. One side of the trapezoidal tube abuts against the inner side of the aluminum template, and the two ends of the trapezoidal tube are bevels to avoid interference between adjacent trapezoidal tubes.

[0017] The principle of this utility model is as follows: First, install the aluminum template and the self-locking reinforcing back rib; then, splice the aluminum templates together to form a fully enclosed small space; insert the reinforcing screw from the outside to lock the self-locking reinforcing back rib, and cooperate with the external reinforcing back rib to reinforce the small space so that the self-locking reinforcing back rib presses down on the aluminum template to achieve the purpose of fixation.
