Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a structural column corner template reinforcement device. Background Art

[0002] During the construction of secondary structures, the L-shaped corner column formwork is often reinforced at the construction site by using wooden planks as the primary and secondary keels, and then using step-by-step tightening of autoclaved aerated blocks for fixation. The step-by-step tightening will cause rows of round holes to appear on the blocks, causing the blocks to crack, reduce strength, and thus make the entire wall insufficient in strength.

[0003] Utility model patent number CN221609486U discloses an L-shaped wall corner structural column formwork reinforcement structure, comprising internal and external corner formwork installed at the internal and external corners of the L-shaped wall corner structural column. The external and internal corner formworks are respectively provided with internal and external corner reinforcements. The structure also includes a set of fully threaded screws that pass through the internal and external corner formworks, the internal and external corner reinforcements, and are restrained by stoppers to form the formwork reinforcement structure. The fully threaded screws avoid the wall. By combining and connecting the external and internal corner reinforcements to reinforce the secondary structural column formwork, this structure avoids the problem of drilling holes in the masonry when reinforcing traditional L-shaped corner structural column formwork. However, in this structure, two full-thread screws form a group and are arranged in an eight-shaped shape. A group of screw mounting seats corresponding to the full-thread screws are respectively provided on the inner side of the internal corner reinforcement and the outer side of the external corner reinforcement. Therefore, the full-thread screws and the screw mounting seats are not perpendicular to the reinforcement and the template at 90 degrees, and the wall needs to be avoided during installation, resulting in high requirements for the installation angle of the screw mounting seats. The installation angle and position need to be very precise for use, which is inconvenient to install and not easy to use. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model aims to provide a structural column corner template reinforcement device that can solve the above-mentioned problems.

[0005] A structural column corner formwork reinforcement device comprises a internal corner formwork, a external corner formwork, and a screw. The internal corner formwork and the external corner formwork are respectively arranged on the inner and outer sides of the structural column. External and internal corner formworks are respectively provided with external and internal corner reinforcements.

One end of the screw is rotatably inserted into the inner sleeve, and the other end is rotatably sleeved with a limiter.

[0006] Furthermore, it also includes an outer sleeve, which is fixed to the outside of the male corner reinforcement. The outer sleeve is perpendicular to the male corner reinforcement and is arranged corresponding to the inner sleeve. The screw slides through the outer sleeve, and the limit member abuts against the end of the outer sleeve away from the male corner reinforcement.

[0007] Furthermore, a sleeve is sleeved on the screw, and the sleeve is arranged between the internal angle template and the external angle template.

[0008] Furthermore, a first connecting tube is provided at one end of the two inner sleeves close to each other. The first connecting tube is vertically arranged, and the two inner sleeves are fixedly connected to the first connecting tube.

[0009] Furthermore, a second connecting pipe is provided between two adjacent first connecting pipes, and the second connecting pipe is detachably connected to the first connecting pipe.

[0010] Furthermore, the lower end of the first connecting pipe at the lowest end is detachably connected to a third connecting pipe, and the lower end of the third connecting pipe is in contact with the ground.

[0011] Furthermore, a fixing plate is fixed to the outer side of the lower end of the third connecting pipe, and the bottom surface of the fixing plate is in contact with the ground.

[0012] Furthermore, the first connecting pipe is threadedly connected to the second connecting pipe and the third connecting pipe.

[0013] Furthermore, a group of square timbers are arranged between the external corner template and the external corner reinforcement piece, and adjacent square timbers are arranged at intervals and avoid the screw rods.

The other end allows a screw to be rotatably inserted, connecting the screw and abutting the internal corner reinforcement. A stopper is provided at the other end of the screw, allowing the screws to pull against each other, cooperating with the external and internal corner reinforcements to reinforce the internal and external corner formwork. The inner sleeves and screws in this utility model are perpendicular to the corresponding formwork and reinforcement, ensuring a strong reinforcement effect while facilitating installation and turnover.
