[0001] The invention relates to the technical field of steel pipe fixing, in particular to a simple clamp for assisting the installation of square steel of a formwork frame. Background Art

[0002] With the development of the construction industry, the use of interlocking formwork systems is increasing in various construction projects, especially for tall formwork support systems. To reduce the construction cost of interlocking formwork systems, the only way is to increase the spacing between interlocking poles. The formwork system uses a beam-slab shared pole system. Double-grooved joists replace the bottom support poles of the beams, and the top brackets on the double-grooved joists house two layers of square steel. The spacing of the upper layer of square steel can be adjusted to ensure that the formwork system can adapt to beams of different sizes. This measure can minimize the number of poles used, thereby reducing the rental cost of interlocking poles.

[0003] After searching, the patent document with announcement number CN221972983U discloses a simple clamp for fixing square steel pipes, including a non-standard U-bolt clamp, the circular end of the non-standard U-bolt clamp is a Π-shaped right-angle clip, and the two legs of the Π-shaped right-angle clip are respectively welded to the U-bolt legs; the washer of the non-standard U-bolt clamp is a mountain-shaped clip, and the mountain-shaped clip is a steel structure fastener; the use state of the non-standard U-bolt clamp is that the Π-shaped right-angle clip tightly clamps the square steel pipe, and the mountain-shaped clip tightly clamps the double steel pipes at a right angle to the square steel pipe, thereby achieving a firm simple clamp for fixing square steel pipes.

[0004] However, the above invention has the following shortcomings: although the above patent can clamp the square steel, the fixing method is relatively simple, and the area of the force-supporting surface is small when the common square steel is placed crosswise, which makes it easy to have an unstable center of gravity when laying the template on the square steel, and thus places extremely strict requirements on the balance and professionalism of the operators, so there are certain limitations.

[0028] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] The present invention provides a simple fixture for assisting the installation of square steel of a formwork frame through improvement. The technical solution of the present invention is:

[0030] like Figures 1 to 6 As shown, an embodiment of the present invention provides a simple clamp for assisting the installation of square steel of the formwork frame, including an upper square steel 1 and a lower square steel 2, which are arranged vertically in a cross, and also include a U-shaped clamp 3 and a reinforcement component 4. The U-shaped clamp 3 is set to effectively achieve the stability of the connection between the upper square steel 1 and the lower square steel 2, and the cooperation of the reinforcement component 4 can further improve the stability of the connection.

[0031] The U-shaped clamp 3 is arranged between the upper square steel 1 and the lower square steel 2.

[0032] The U-shaped clamp 3 includes a pair of Y-shaped clamping edges 31, and a connecting rod 32 is fixedly connected between the bottoms of the pair of Y-shaped clamping edges 31. The pair of Y-shaped clamping edges 31 are respectively connected to a fastening bolt 1 33 and a fastening bolt 2 34 through threads near the upper square steel 1 and the lower square steel 2. The provision of the fastening bolt 1 33 and the fastening bolt 2 34 not only facilitates simple and quick operation by the staff, but also ensures that the U-shaped clamp 3 can be stably installed on the upper square steel 1 and the lower square steel 2, thereby playing a role of auxiliary reinforcement.

[0033] The reinforcement component 4 is arranged on the Y-shaped clamping edge 31.

[0034] The reinforcement component 4 includes a fixing bolt 41 which is threadedly connected to the Y-shaped clamp edge 31, and a support rod 42 is movably installed on the fixing bolt 41. A U-shaped support block 43 is fixedly installed on one side of the support rod 42. The movably installed support rod 42 can improve the flexibility of the reinforcement component 4, thereby ensuring the normal use of the U-shaped clamp 3. In addition, the setting of the support rod 42 and the U-shaped support block 43 can provide a stable installation foundation for the reinforcement component 4.

[0035] Furthermore, an adjusting screw 45 is threadedly connected to the middle of the U-shaped support block 43, and a moving block 46 is fixedly installed on the end of the adjusting screw 45 through a bearing. A plurality of anti-sliding blocks 47 are fixedly installed at equal intervals on one side of the moving block 46. The adjusting screw 45 is arranged to move with the moving block 46, and then move with the anti-sliding block 47 until it conflicts with the upper square steel 1, thereby further improving the installation stability between the clamp and the square steel.

[0036] Furthermore, limiting grooves 44 are respectively provided at the middle and end parts of the support rod 42, and the limiting grooves 44 slide in cooperation with the moving block 46. The setting of the limiting grooves 44 can improve the stability of the movement of the moving block 46, thereby ensuring that the moving block 46 and the anti-sliding block 47 always achieve the effect of horizontal movement, thereby ensuring that the reinforcement component 4 works normally.

[0037] Furthermore, a socket 48 is provided at the end of the support rod 42, and an L-shaped baffle 49 is fixedly installed on the Y-shaped clamping edge 31 near the support rod 42. An insertion rod 410 slides through the L-shaped baffle 49, and the insertion rod 410 is inserted into the inside of the socket 48. The L-shaped baffle 49 and the insertion rod 410 can improve the fixing effect of the support rod 42, thereby providing protection for the operation of the adjusting screw 45 and the moving block 46.

[0038] Furthermore, a pair of supporting rods 5 are symmetrically fixedly installed in the middle of each Y-shaped clamping edge 31, and a supporting plate 6 is fixedly installed at the end of each supporting rod 5. The surface of the supporting plate 6 is in contact with the bottom of the upper square steel 1. The setting of the supporting rods 5 and the supporting plates 6 can provide a certain supporting effect for the upper square steel 1.

[0039] Furthermore, a reinforcing rod 7 is fixedly installed between a pair of supporting rods 5, and the middle part of the reinforcing rod 7 is connected with a fastening bolt 3 8 through a thread. The use of the provided reinforcing rod 7 can not only improve the structural strength between the supporting rods 5, but also further improve the friction between the U-shaped clamp 3 and the lower square steel 2 by using the fastening bolt 3 8, thereby further improving the stability of the clamp installation.

[0040] Specific working principle: After the upper square steel 1 and the lower square steel 2 are installed, the U-shaped clamp 3 is clamped between the upper square steel 1 and the lower square steel 2, and the fastening bolt 1 33 and the fastening bolt 2 34 on the Y-shaped clamping edge 31 are tightened, so as to achieve the clamping and fixing effect of the clamp and the upper square steel 1 and the lower square steel 2. At the same time, the support rod 42 is rotated to the L-shaped baffle 49 and fixed with the insertion rod 410. By rotating the adjusting screw 45, the moving block 46 and the anti-sliding block 47 are moved until they conflict with the upper square steel 1. The anti-sliding block 47 can effectively increase the contact friction, thereby further improving the clamping and fixing effect between the clamp and the square steel.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
