Description

Technical Field

[0001] The utility model relates to the technical field of the construction of square columns in the frame structure of building houses, in particular to a novel fastening buckle for square column formwork. Background Art

[0002] In the current field of building construction, the traditional formwork support system for frame columns usually uses steel pipes, tie bolts and square timbers for combined reinforcement. This construction method is cumbersome in operation, has a large amount of installation and reinforcement work, and low construction efficiency. The steel pipe has slightly worse stiffness than the horizontal keel of the fastening buckle, and the steel pipe is often compressed and deformed, resulting in the problem that the squareness and verticality of the cast structural column exceed the allowable values, and the construction quality cannot be guaranteed. At the same time, the holes of the tie bolts cause the formwork to be easily damaged and leak slurry, and the number of times the formwork can be recycled is greatly reduced. And with the increasing expansion of the construction scale, the consumption of building materials is increasing day by day, the forest resources are becoming increasingly scarce, and the contradiction between domestic wood supply and demand is becoming increasingly prominent. It is imperative to save and substitute wood in the field of building construction. Since the fastening buckle reinforcement products were promoted and launched on the market, they have now blossomed everywhere in construction sites across the country, replacing the traditional fastening methods. The common fastening buckle reinforcement has a total of four strip plate installation points, resulting in a relatively low installation efficiency. There is also the problem that the stiffness of the fastening buckle is poor, affecting the verticality and squareness of the frame column. Content of the Utility Model

[0017] The following will be described in detail with reference to the embodiments of the present utility model with reference to the drawings. Specific Embodiments

[0018] The present utility model will be further described below with reference to the drawings and embodiments:

[0019] As Figures 1 to 3As shown in the figure, a new type of fastening buckle for square column formwork includes: two groups of foldable strip plates and a positioning pin 1; the foldable strip plates include: a first strip plate 2, a second strip plate 3, a rotor 4, and an angle code 5; the heads of the first strip plate 2 and the second strip plate 3 are rotatably connected through the rotor 4, an angle code 5 is provided on the first strip plate 2, the angle code 5 abuts against the second strip plate 3, an O-shaped connecting part 6 is provided at the tail of the first strip plate 2, and a plurality of first positioning strip holes 7 are opened on the O-shaped connecting part 6, and a plurality of second positioning strip holes 8 are opened at the tail of the second strip plate 3. The tails of the second strip plates 3 of the two groups of foldable strip plates are respectively inserted into the O-shaped connecting parts 6 of the other group of foldable strip plates to form a square frame structure, and the positioning pin 1 is inserted into the corresponding first positioning strip hole 7 and the second positioning strip hole 8.

[0020] Specifically, the two groups of foldable strip plates are respectively clamped with the tails of the second strip plates 3 through two O-shaped connecting parts 6 to form a square frame structure as the horizontal keel. The O-shaped connecting part is used to replace the common U-shaped card slot, making the lap joint more firm. The O-shaped connecting part 6 and the adjacent second strip plate 3 are positioned by the positioning pin 1 inserted into the corresponding positioning strip holes of the two, and the positioning pin 1 limits the movement of the adjacent second strip plate 3 towards the outside of the square frame.

[0021] The long side of the first positioning strip hole 7 is arranged in the same direction as the long side of the first strip plate 2, and the second positioning strip hole 8 is arranged in the same direction as the long side of the second strip plate 3. The multiple first positioning strip holes 7 on the same plate and the multiple second positioning strip holes 8 on the same plate are all parallel and staggered. The structures of the first positioning strip hole 7 group and the second positioning strip hole 8 group increase the number of positioning points of the positioning pin 1, that is, increase the use range of the square frame and improve its versatility.

[0022] The positioning pin 1 is a wedge-shaped pin, and a plurality of serial small holes are opened up and down on the positioning pin 1. It is used to fix the positioning pin 1 to prevent the positioning pin 1 from loosening during the construction process.

[0023] The first strip plate 2 and the second strip plate 3 are Q355 reinforced I-beams or H-beams. The strength is 4 times that of ordinary steel pipes.

[0024] The lengths of the first strip plate 2 and the second strip plate 3 are between 468 mm and 2168 mm, and the length of the O-shaped connecting part 6 is within 350 mm.

[0025] The apertures of the first positioning strip hole 7 and the second positioning strip hole 8 are 40 mm * 15 mm.

[0026] The fixed limiting angle of the angle code 5 is 89°. Ensure that the inner angle of the foldable strip plate is controlled at 89°, which helps to adapt to the 1° expansion angle of the concrete during construction pouring, making the fastening buckle more firm.

[0027] The utility model limits the inward and outward movement of two pairs of foldable strip plates through the structures of the positioning pin 1, the first positioning strip hole 7 and the second positioning strip hole 8, improving the overall stability of the fastening buckle. Only the installation of two diagonals is involved, shortening the installation and disassembly time. The other two diagonals are connected by the rotor 4 and limited by the 89° fixed angle code 5 to ensure the stable support of the inner square column formwork, thereby ensuring the quality and appearance of the square column pouring project.

[0028] The above has made an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited by the above methods. As long as various improvements are made by adopting the method concept and technical solution of the utility model, or directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
