Square column buckles can ensure the stability and accuracy of the formwork during concrete pouring, thereby ensuring construction quality and safety.

[0003] Square column buckles are mainly used to reinforce square column formwork with a size between 400-3000mm. They are used for a relatively simple purpose, but the effect is significant. In construction, the use of square column buckles can save materials, increase construction speed, and at the same time ensure the reinforcement effect of the formwork, avoiding problems such as expansion and explosion of the square column formwork. In addition, square column buckles have many advantages in the reinforcement construction process, and gradually replace the old square column formwork reinforcement method.

[0004] The utility model with patent application number 201921122615.6 discloses an aluminum alloy formwork reinforced force structure. When installing the square column buckle, it is necessary to surround the four bending rods into a square frame and then insert the wedge block to fix it; the front and back sides need to be considered during the connection of the four bending rods, and the front and back sides can be spliced. At the same time, when it is not fixed by the wedge block, it needs to be fixed manually. Therefore, the existing square column buckle has certain inconveniences during installation.

[0012] The limit pin includes a connecting sleeve, a pin body and a spring. Both ends of the connecting sleeve are open. The pin body is slidably connected to the connecting sleeve. A plug is threadedly connected to the open upper end of the connecting sleeve. The spring is arranged in the connecting sleeve. Both ends of the spring are respectively against the plug and the pin body. The pin body can be extended through the opening at the lower end of the connecting sleeve. The connecting sleeve is provided with a circle of convex edges, and the movement of the pin body is limited by the convex edges.

[0013] The lower end of the pin body is hemispherical.

[0014] It also includes an L-shaped fixing frame, which includes an L-rod and an L-plate.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-7 As shown, an adjustable column form reinforcement tool includes a fixing rod 1, a wedge-shaped pin 2 and a limit pin 3. Four fixing rods 1 are provided, and the four fixing rods 1 are plugged in and surrounded to form a square frame. The difference between this tool and the existing common square column buckles lies in the fixing rod 1 itself, which does not need to consider the front and back, and can realize the plug-in between the rods. Secondly, a limit pin 3 is also provided, which can perform preliminary fixation (limitation). As for the rest, the structure of the wedge-shaped pin 2 is the same as the existing structure. At the same time, the insertion length between the four fixing rods 1 can be adjusted according to the square column formwork, so as to adapt to the fixation of square column formworks of different sizes.

[0029] The fixing rod 1 is an integrated structure, which includes a slot portion 10, an arc-shaped transition portion, a fixing portion 12 and a plug-in portion 13 from left to right; the plug-in portion 13 has a C-shaped opening 100, and the plug-in portion 13 and the C-shaped opening 100 are at the same level. The slot portion 10 and the plug-in portion 13 are used for plug-in connection, and the fixing portion 12 is mainly in contact with the square column template for compression and fixing.

[0030] For the convenience of description, the four fixing rods 1 are respectively named as fixing rod one 14 , fixing rod two 15 , fixing rod three 16 and fixing rod four 17 .

[0031] The plug-in process is as follows: insert the plug-in portion 13 of the fixing rod 14 into the C-shaped opening 100 of the fixing rod 2 15; insert the plug-in portion 13 of the fixing rod 2 15 into the C-shaped opening 100 of the fixing rod 3 16; insert the plug-in portion 13 of the fixing rod 4 17 into the C-shaped opening 100 of the fixing rod 1 14. As the insertion is gradually carried out, the C-shaped opening 100 of the fixing rod 4 17 will clamp the plug-in portion 13 of the fixing rod 3 16, and the arc-shaped transition portion will not hinder the installation of the fixing rod 4 17.

[0032] A limiting pin 3 is connected to the slot portion 10 of each fixing rod 1, and the slot portion 10 is provided with a corresponding connecting through hole and a connecting column 4; the limiting pin 3 is fixedly connected to the connecting column 4, and the end of the limiting pin 3 can extend through the connecting hole 5. Therefore, after each fixing rod 1 is plugged in, it can be initially fixed by the limiting pin 3. For example: when the plug-in portion 13 of the fixing rod 1 14 is inserted into the C-shaped opening 100 of the fixing rod 2 15, the plug-in portion 13 of the fixing rod 1 14 is pressed by the limiting pin 3 on the fixing rod 2 15, preventing it from moving at will.

[0033] Therefore, by providing the stop pin 3, the fixing rod 1 14, the fixing rod 2 15, the fixing rod 3 16 and the fixing rod 4 17 can be initially fixed after being sequentially inserted, thereby hindering the movement of each rod and facilitating the insertion and assembly. After the fixing rod 1 14, the fixing rod 2 15, the fixing rod 3 16 and the fixing rod 1 are initially fixed by the stop pin 3, the wedge-shaped plug pin 2 is inserted into the slot 130 corresponding to each plug-in part 13 for final tightening.

[0034] Furthermore, the above-mentioned limit pin 3 is fixedly connected to the connecting column 4 through a thread, and the upper and lower positions of the limit pin 3 in the connecting column 4 can be adjusted as needed, so as to adjust the height of the limit pin 3.

[0035] Furthermore, the above-mentioned limit pin 3 includes a connecting sleeve 30, a pin body 31 and a spring 32, and both ends of the connecting sleeve 30 are open. The connecting sleeve 30 is provided with an external thread connected to the connecting column 4, and the connecting column 4 is provided with a corresponding internal thread. The overall position of the limit pin 3 can be adjusted by rotating the connecting sleeve 30. Specifically: a hexagonal structure (nut-shaped) is provided at the upper end of the connecting sleeve 30 to facilitate the rotation of the connecting sleeve 30.

[0036] The pin body 31 is slidably connected to the connecting sleeve 30. The upper open end of the connecting sleeve 30 is connected with a plug 33 through a thread. The spring 32 is arranged in the connecting sleeve 30. The two ends of the spring 32 are respectively against the plug 33 and the pin body 31. The position of the plug 33 can be adjusted by rotating it to change the pre-compression force of the spring 32. Specifically, a straight groove is provided on the rotating plug 33 to facilitate the rotation of the connecting plug 33.

[0037] The pin body 31 can extend through the opening at the lower end of the connecting sleeve 30. The connecting sleeve 30 is provided with a circle of flanges 34, and a protrusion is provided at the upper end of the pin body 31. When the protrusion contacts the flange 34, the movement of the pin body 31 can be restricted to prevent the pin body 31 from moving out of the connecting sleeve 30.

[0038] The lower end of the pin body 31 can extend through the connecting hole 5. When the plug-in portion 13 of the fixing rod 14 is inserted into the C-shaped opening 100 of the fixing rod 2 15, the pin body 31 at the fixing rod 2 15 is lifted up by the plug-in portion 13 of the fixing rod 14, and the spring 32 is compressed to generate elastic potential energy, thereby pressing the plug-in portion 13 of the fixing rod 14 to prevent it from moving at will, thereby achieving the purpose of initial fixation.

[0039] Furthermore, the lower end of the pin body 31 is hemispherical.

[0040] Furthermore, fixing the square column template requires multiple square column buckles, and each square column buckle needs to be spaced a certain distance apart. Currently, it is common to use a template of corresponding width as a reference, which is inconvenient.

[0041] To this end, the tool also includes an L-shaped fixing frame 6, which includes an L-rod 60 and an L-plate 61. The L-plate 61 is slidably connected to the L-rod 60. An adjusting nut 62 is threadedly connected to the L-rod 60, and the end of the adjusting nut 62 can contact the L-plate 61. After the four fixing rods 1 are inserted and surrounded to form a square frame to fix the square column template, when installing the next group of four fixing rods 1, the L-shaped fixing frame 6 is installed first, and the L-shaped fixing frame 6 is placed at the corner of the square column template, that is, the connection between the two templates.

[0042] Specifically, the lower end of the vertical rod 63 is contacted with the installed fixing rod 1; then the L rod 60 and the L plate 61 are respectively hooked on the vertical ribs of the adjacent templates by tightening the adjusting nut 62, so as to achieve the purpose of reinforcement. Four L-shaped fixing frames 6 are arranged between the two square column buckles.

[0043] When installing the next set of four fixing rods 1, the fixing rods 1 of this set are brought into contact with the upper ends of the vertical rods 63 in the installed L-shaped fixing frame 6, so that the spacing between the two sets of square column buckles can be ensured. That is, the length of the vertical rod 63 is the spacing between the two sets. That is, it is necessary to use a template or caliper for measurement or reference.

[0044] Only the preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention, and various changes should be included in the protection scope of the present invention.
