The lower edge of the supporting plate is cold-bent and provided with a retaining shoulder and a positioning piece, the retaining shoulder is used for preventing the square tube from rotating when fastening the firmware, and the positioning piece is used for statically placing the pin plate. The round pin board is provided with an arc-shaped hole matched with the limit nail and a positioning edge matched with the positioning sheet, the round pin board is installed between the nail cap of the limit nail and the support plate through the arc-shaped hole to form a whole, and the arc-shaped hole is matched with the limit nail to enable the round pin board to move towards the square pipe so as to fix the square pipe.

Further, in order to limit the rotation space of the pin plate, a convex point is punched at the rear part of the support plate. In order to increase the strength of the supporting plate, the middle part of the supporting plate is cold-pressed with a raised reinforcing rib. In order to facilitate the loading, transporting and counting of the square tube fastening firmware, a hoisting hole is processed at the rear end of the supporting plate.

Furthermore, in order to improve the stress of the square tube, a tube supporting plate is cold-bent at the upper edge of the supporting plate.

The utility model has the beneficial effects that: the positioning edge is matched with the positioning sheet to realize relative rest of the pin plate, so that the square tube can be conveniently placed. The fastening of square pipe and the dismantlement of square tube fastening firmware only need strike, and the ann tears the convenience open, is applicable to the building site construction.

Detailed Description

The fastening structure of the square tube fastener of the utility model is shown in figure 1, figure 2 and figure 3, and comprises a supporting part 1 and a pin plate 2 which are connected into a whole. The supporting component 1 comprises a supporting plate 10, a pin 11, a blocking shoulder 12, a protruding reinforcing rib 13, a positioning piece 14, a lifting hole 15, a convex point 16 and a limiting pin 17. The middle part of the front end of the supporting plate 10 is welded with a pin 11 (the position matched with the aluminum template is the front), and the lower edge is bent with a retaining shoulder 12. The pin 11 corresponds to the mounting round hole on the aluminum template, and a pin sheet hole is processed on the pin and matched with the pin sheet. Keep off shoulder 12 and form by backup pad 10 cold-bending, its crooked direction is the direction of insertion of pin 11, and when the installation round hole cooperation on pin 11 and the aluminum mould board, keep off shoulder 12 and block the template boundary bar 4 of aluminum mould board, prevent that support component 1 from rotating around pin 11, keep the top edge level of backup pad 10, make things convenient for the level of square pipe 3 to place, as shown in figure 5. And a limiting nail 17 is fixedly welded at the rear end of the support plate 10, a positioning piece 14 is bent at the lower edge, and the limiting nail 17 and the positioning piece 14 are matched with the pin plate 2 for use. The pin plate 2 is provided with an arc-shaped hole 21 matched with the limit nail 17 and a positioning edge 22 matched with the positioning sheet 14. The pin plate 2 is installed between the head of the limit pin 17 and the support plate 10 as one body. The arc-shaped hole 21 can freely move up and down or rotate along the limit pin 17. The limit pin 17 can also be riveted on the support plate 2 as long as the movement of the pin plate 2 is realized. To define the rotation space of the pin plate 2, a convex point 16 is punched at the rear of the support plate 10. In order to increase the strength of the support plate 10, raised ribs 13 are cold pressed in the middle of the support plate. In order to facilitate the transportation of the utility model, a lifting hole 15 is processed at the rear end of the supporting plate 10, and a plurality of square tube fastening fasteners can be bound together by iron wires or ropes, so that the transportation and the counting are convenient.

Fig. 4 is a working schematic diagram of the pin plate, which shows the movement track of the pin plate 2 from top to bottom, when the positioning edge 22 of the pin plate 2 is lapped on the positioning sheet 14 of the support plate 10, the opening of the pin plate is the largest and is kept static, and the square tube 3 can be smoothly placed at this time. After square pipe 3 is put into, lift and rotate cotter plate 2, location limit 22 breaks away from locating piece 14, and cotter plate 2 falls under the action of gravity, and the arc hole 21 of cotter plate 2 cooperates with stop pin 17 for cotter plate 2 antedisplacement, move to 3 directions on the square pipe promptly, thereby fixed square pipe 3.

FIG. 5 is a using state diagram of the square tube fastening fastener of the utility model, wherein a pin 11 is inserted into a mounting hole of a template edge rib 4, a retaining shoulder 12 is abutted against the template edge rib 4, and the pin 11 is inserted into a pin piece 5 and knocked, thereby realizing the fixing of the square tube fastening fastener. The positioning edge 22 is lapped on the positioning sheet 14 and the square tube 3 is put in. And rotating the pin plate 2, enabling the pin plate 2 to fall down, and knocking the pin plate to fix the square pipe 3. After concrete pouring and curing of the wall body, the movable pin plate 2 is knocked upwards, the positioning edge 22 is put on the positioning plate 14 again, and the lower pipe 3 is taken out. Then the movable pin piece 5 is knocked, and the pin 11 is pulled out, so that the fastening piece of the square tube can be separated from the template. The fastening of side's pipe and the dismantlement of square tube fastening firmware all adopt to strike the action, do not use specialized tool, and the ann tears the convenience open, is applicable to the building site construction.

In order to improve the stress state of the square tube 3, a support tube plate 18 may be cold-bent at a position where the square tube 3 is placed on the upper edge of the support plate 10, as shown in fig. 6.
