Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, specifically to a composite material template square tube clip. Background Technology

[0002] In the construction industry, formwork systems are commonly used to support and shape concrete structures during concrete pouring. Composite material formwork, due to its lightweight, corrosion resistance, and recyclability, is widely used in high-rise buildings and large-scale projects. However, existing reinforcement fasteners present significant problems when connecting composite material formwork, tie rods, and square tubing. For example, common reinforcement fasteners are mostly metal clips or hooks, which often cannot quickly adapt to the structural characteristics of composite material formwork, leading to low installation efficiency. Industry practice shows that installing existing fasteners typically requires manually tightening multiple screws, taking several minutes, and they are prone to loosening due to vibration. Especially during concrete pouring, the strong vibrations of the vibrator can loosen screws or clips, causing formwork misalignment or bursting (i.e., formwork cracking and concrete leakage), which not only increases the risk of rework but may also lead to safety accidents. The limitations of traditional reinforcement systems include: 1. Design flaws, such as the lack of a reliable locking mechanism, making screws prone to coming loose under vibration; 2. Poor versatility, with existing fasteners struggling to adapt to different sizes of square tubing and tie rods. Furthermore, the widespread adoption of composite material templates has exacerbated these defects: for example, their smooth surfaces lead to insecure fixation, and traditional fasteners cannot adjust the locking force.

[0003] Therefore, it is crucial to develop a new type of snap-fit ​​that can provide quick connection, prevent screws from loosening, and enhance overall reinforcement. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a square tube buckle for composite material templates, so as to solve the problem of inconvenient installation and easy loosening of existing reinforcing fasteners in composite material templates, which leads to template bursting.

The L-shaped locking plate 31 includes a supporting part 311 and a mounting part 312 arranged perpendicularly to each other. The supporting part 311 abuts vertically against the connecting plate 13, and the mounting part 312 is arranged parallel to the connecting plate 13. One end of the screw 32 is vertically fixed to the front end of the connecting plate 13, and the other end passes through a screw hole provided on the mounting part 312 and is locked by the nut 33. The front end of the mounting part 312 is also provided with a second connecting platform 313, which corresponds to the first connecting platform 14. The connecting pin group 4 includes a long pin 41 and a short pin 42 that are arranged correspondingly to each other. One end of the long pin 41 is fixedly set on the first connecting platform 14, and one end of the short pin 42 is fixedly set on the second connecting platform 313.

[0026] In a preferred embodiment, the first connecting platform 14 is connected to the front end of the connecting plate 13 via a first oblique connecting portion 15, so that the first connecting platform 14 moves closer to the second connecting platform 313.

[0027] In a preferred embodiment, the second connecting platform 313 is connected to the front end of the mounting portion 312 via the second oblique connecting portion 314, so that the second connecting platform 313 moves closer to the first connecting platform 14.

[0028] In a preferred embodiment, the connecting plate 13, the first oblique connecting portion 15, and the first connecting platform 14 are integrally formed; the mounting portion 312, the second oblique connecting portion 314, and the second connecting platform 313 are integrally formed.

[0029] In a preferred embodiment, the first limiting plate 11, the second limiting plate 12, and the connecting plate 13 are integrally formed.

[0030] In a preferred embodiment, the nut 33 is further provided with mounting wings 331 on both sides of its bottom. The mounting wings 331 allow the nut to be tightened by tapping it with a hammer when a wrench is not applicable.

[0031] In a preferred embodiment: a notch is provided at the rear end of the second pin groove 121; the square tube limiting pin 2 is wedge-shaped; the tail 21 of the square tube limiting pin 2 is bent backward, and a first limiting protrusion 22 is provided at the lower end of the tail 21 away from the connecting plate 13; a second limiting protrusion 131 is provided on the rear end of the connecting plate 13 facing the square tube limiting pin 2; the tail 21 of the square tube limiting pin 2 cooperates with the second limiting protrusion 131 for limiting, and the first limiting protrusion 22 cooperates with the second pin groove 121 for limiting, so as to limit the tail 21 of the square tube limiting pin 2 in the second pin groove 121 and prevent it from coming out.

[0032] In a preferred embodiment, a support platform 122 is vertically disposed at the front end of the second limiting plate 12. The support platform 122 increases the contact surface between the square tube clip and the reinforcing ribs 101 of the reinforced building formwork 100, thus preventing excessive stress concentration and damage to the new reinforced building formwork.

[0033] See Figure 5-6 In another embodiment of this utility model, the working principle of the square tube buckle is as follows: Install multiple square tube clips at the corresponding positions of the reinforcing ribs where square tubes 200 need to be added to the reinforced formwork 100: First, the tie plate 300 is inserted between the adjacent reinforcing bars 101 of two adjacent reinforced building formwork 100, and the mounting holes on the tie plate 300 are aligned with the mounting holes 102 of the reinforcing bars 101. Next, the long pin 41 of the buckle body 1 of the square tube buckle is first passed through the mounting hole 102 on the side of the corresponding rib 101 and the mounting hole on the tie plate 300 from the left side; then, the mounting part 312 of the L-shaped locking piece 31 is fitted into the screw 32, while the short pin 42 at the front end is inserted into the mounting hole 102 on the right side of the corresponding rib 101 and mates with the long pin 41, and finally locked by the nut 33; by tightening the nut, the abutting part 311 of the L-shaped locking piece 31 abuts against the connecting plate 13, forming a reaction structure, which applies additional pressure to the mounting part 312 and generates friction to lock the nut position. This design has strong stability and ensures that the vibration generated during concrete pouring will not cause the screw to loosen, thereby preventing the formwork from bursting.

[0034] At this time, the support platform 122 at the front end of the second limiting plate 12 abuts against the rib 101, which plays a supporting role; Then, the square tube limiting pin 2 is pulled upward along the buckle body 1 until the space between the square tube limiting pin 2 and the reinforcing bar 101 is larger than the size of the square tube 200 to be installed (at this time, the first limiting protrusion 22 on one side of the tail 21 of the square tube limiting pin 2 is stuck by the second pin groove 121 to prevent the square tube limiting pin 2 from coming out of the buckle body 1); finally, the square tube 200 is placed on the first limiting plate 11, and the square tube limiting pin 2 is knocked downward until the square tube 200 is horizontally fixed between the back of the reinforced building formwork 100 and the square tube buckle.

[0035] The square tube clips are suitable for composite material formwork, and their connection configuration allows for adjustment of tightness during construction.

[0036] The wedge-shaped square tube limiting pin 2, in conjunction with the buckle body 1, can be used with square tubes 200 of different sizes. During operation, construction workers can flexibly adjust the fit between the reinforced building formwork 100 and the square tube 200 according to the size of the square tube 200, ensuring the flatness of the reinforced building formwork 100. The tail 21 of the square tube limiting pin 2 cooperates with the second limiting protrusion 131 for limiting, and the first limiting protrusion 22 cooperates with the second pin groove 121 for limiting, thus limiting the tail 21 of the square tube limiting pin 2 within the second pin groove 121, allowing it to move within its range of use without detaching from the buckle body. Furthermore, the overall structure of this utility model is compact; installation only requires a one-time snap-in and tightening of the nut, making the installation and disassembly of the square tube buckle very convenient, greatly saving operation time and improving work efficiency. While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
