Description

Technical Field

[0001] The invention belongs to the technical field of square column formwork reinforcement structures, and particularly relates to an external reinforcement device for a square column formwork. Background Art

[0002] The square column formwork is a formwork structure that surrounds a reinforced steel frame constructed by wooden boards or hard boards. Concrete is poured into the square column formwork, and after the concrete solidifies, a square wooden pier support structure is formed. The square column formwork is a formwork structure set up and used on the construction site. After the square column formwork is erected, it needs to be fixed on the outside of the square column formwork. The existing technology generally uses square tubes and tension bolts for locking. The fixing structure of the existing technology generally locks the edge sides of the four sides of the square cone formwork, but cannot be locked synchronously. When a single locking is performed, due to excessive locking force, it is easy to cause the square column formwork to skew on one side, making the final solidified square column part square. Even during the pouring process, due to uneven locking force, concrete leaks, affecting the construction of the entire square column. Summary of the Invention

[0023] like Figures 1 to 7 As shown, the present invention discloses an external reinforcement device for a square column formwork, comprising a corner reinforcement ring 1 and a synchronous locking ring 2, as shown in FIG. Figure 3 As shown, the corner reinforcement ring 1 includes four mutually connected corner reinforcement parts 11, as shown in FIG. Figure 5 As shown, the corner reinforcement portion 11 includes a T-shaped seat 111, a sliding block 112 and two pressure columns 113. The sliding block 112 is slidably arranged at the tail end of the T-shaped seat 111, and the two pressure columns 113 are slidably arranged on the two arms of the T-shaped seat 111. The sliding section of the pressure column 113 can be set to a square. The two arms of the T-shaped seat 111 also open square holes of corresponding sizes. The pressure columns 113 slide on the two arms of the T-shaped seat 111 to form a square. Figure 5 The 90° intersection of the sliding block 112 extends outward on both sides and has two mutually perpendicular inner side surfaces, one end of the pressing column 113 presses against the inner side surface of the sliding block 112, and the other end extends toward the center of the corner reinforcement ring 1; Figure 2 and Figure 5, a guide column 114 is vertically fixed on the sliding block 112, and four guide grooves 211 are opened on the synchronous locking ring 2. The guide grooves 211 are arc-shaped, and the guide column 114 is slidably arranged in the guide grooves 211. Figure 1 As shown, the corner reinforcement ring 1 surrounds the outside of the square column formwork 3, the corner reinforcement part 11 is located at the corner position of the square column formwork 3, and the pressure column 113 is against the side of the corner. As the synchronous locking ring 2 rotates, all the pressure columns 113 are in synchronous expansion and contraction movement.

[0024] In this solution, four corner reinforcements 11 for pressing the four corners of the square column formwork 3 are provided. The corner reinforcement 11 presses the 90° clamping surface of the square column formwork 3 through two pressing columns 113, and the sliding block 112 slidingly arranged on the T-shaped seat 111 presses the pressing columns 113 at the same time, so that the sliding block 112 presses the two pressing columns 113 to synchronously press the two sides of the corners of the square column formwork 3 while moving along the T-shaped seat 111. The guide column 114 provided on the sliding block 112 is slidably provided in the guide groove 211 provided on the synchronous locking ring 2. The synchronous locking ring 2 is annularly integrated. As the synchronous locking ring 2 rotates, the four arc-shaped guide grooves 211 cause the guide column 114 to move along the cylindrical direction. This direction is the pressing direction of the sliding block 112. At this time, the eight mortgage columns can be synchronously moved by rotating the synchronous locking ring 2 to press the square column formwork 3 The four corners of the square column formwork 3 are pressed against the clamping surfaces; when using this reinforcement device, the corner reinforcement ring 1 is first preliminarily fixed to the outside of the square column formwork 3, and then the guide groove 211 on the synchronous locking ring 2 is engaged with the guide column 114 on the corner reinforcement ring 1. After the preliminary fixation, the synchronous locking ring 2 is directly rotated to complete the four-sided fixation of the square column formwork 3. This device can synchronously squeeze and fix the four panels of the square column formwork 3 by synchronously expanding and contracting eight pressure columns 113. Compared with the fixation of a single corner, this fixing method makes the four corners of the square column formwork 3 evenly stressed and pressed synchronously, avoiding the uneven pressing force caused by the pressing of a single corner and the skewness of the square column formwork 3, and avoiding the squeezing and leakage of concrete due to the uneven pressing force of the square column formwork 3, ensuring the rotation of the synchronous locking ring 2 of the constructed square column formwork 3, and all the pressure columns 113 are in a synchronous expansion and contraction movement with four corners square.

[0025] In this embodiment, the corner reinforcement ring 1 further includes four hexagonal locking columns 12, such as Figure 3 and Figure 6As shown, threaded connecting rods 115 are fixedly connected to both sides of the T-shaped seat 111, and internal threads with opposite rotation directions are provided on the inner sides of the two ends of the hexagonal locking column 12. The hexagonal locking column 12 is threadedly connected to the threaded connecting rods 115, so that the four corner reinforcement parts 11 are connected adjacently. This structure facilitates the pre-fixation and disassembly of the entire corner reinforcement ring 1. When pre-installing the corner reinforcement ring 1, the hexagonal locking column 12 is connected to the threaded rod. Rotating the hexagonal locking column 12 can simultaneously pull back the threaded rods at both ends, so that the four corner reinforcement parts 11 are positioned at the four corners of the square column template 3. This device is used for the preliminary positioning of the corner reinforcement ring 1, is easy to install, has smooth length adjustment, and a stable threaded connection.

[0026] In this embodiment, Figure 5 and Figure 7 The outer end of the sliding block 112 is also fixedly connected to a support base 116, on which a shaft 117 is provided for vertical rotation, and a gear 118 is coaxially fixed to the shaft 117. The outer side of the synchronous locking ring 2 is provided with gear teeth, and the gear 118 is meshed with the outer side of the synchronous locking ring 2; the support base 116 is also provided with a worm 119 for horizontal rotation, and the outer side of the middle section of the shaft 117 is provided with gear teeth, and the worm 119 is meshed with the shaft 117. The end of the worm 119 is provided with a hexagonal Countersunk hole 1191. In this structure, the hexagonal countersunk hole 1191 at the end of the worm 119 is rotated by a rotating device. The rotation of the worm 119 drives the shaft 117 to rotate. The rotation of the shaft 117 drives the rotation of the entire synchronous locking ring 2. The gear 118 meshing structure arranged at the four corners of the corner reinforcement 11 can significantly adjust the position of the synchronous locking ring 2, and the connection method of the worm gear 119 can avoid the rotation of the synchronous locking ring 2 after locking. The locking rotation of the synchronous locking ring 2 can be performed on any corner reinforcement 11.

[0027] In this embodiment, as shown in 4 Figure 5 As shown, the pressure column 113 includes a sliding column 1132, a long pressure plate 1131 and an adjusting platform 1133. One end of the sliding column 1132 is fixedly connected by the long pressure plate 1131, and the other end is threadedly connected to the adjusting platform 1133. The adjusting platform 1133 is pressed against the inner side of the sliding block 112. The sliding block 112 is provided with a sliding groove 1111. The sliding column 1132 passes through the adjusting platform 1133 and penetrates into the sliding groove 1111. The sliding direction and axial rotation of the pressure column 113 are limited by the two arms of the T-shaped seat 111; the pressure length of the pressure column 113 can be adjusted by rotating the adjusting platform 1133. By adjusting the length of the pressure column 113, the angle reinforcement part 11 can be prevented from being skewed due to the unevenness of the pressure surface of the square column formwork 3 when pre-fixing the angle reinforcement ring 1.

[0028] In this embodiment, Figure 2 and Figure 4 As shown, there are two synchronous locking rings 2, and the two synchronous locking rings 2 are fixedly connected by a connecting rod 23. Guide columns 114 are provided on the upper and lower sides of the sliding block 112. The two synchronous locking rings 2 are located on the upper and lower sides of the sliding block 112. There are two gears 118 provided on the shaft 117 and they are respectively engaged with the synchronous locking rings 2 on the upper and lower sides. In this structure, the two synchronous locking rings 2 can synchronously push the guide columns 114 on the upper and lower sides of the sliding block 112 to ensure that the sliding block 112 is subjected to uniform force. The two gears 118 are simultaneously driven by a shaft 117, and a shaft 117 is rotated through a worm 119. The entire synchronous locking ring 2 is still locked by the worm 119 structure, which further improves the stability of this reinforced structure.

[0029] In this embodiment, Figure 4 As shown, the synchronous locking ring 2 includes four driving blocks 21 and four connecting beams 22. The guide grooves 211 are provided on the driving blocks 21. The driving blocks 21 and the connecting beams 22 are connected end to end at intervals to form a square ring. This structure forms the four sides of the synchronous locking ring 2 into straight lines. The gear teeth are provided on the side edges of the driving blocks 21. This structure makes the entire synchronous locking ring 2 square, avoiding interference with other structures and impact on installers due to the excessive size of the synchronous locking ring 2. This structure can also be set as a disassembly structure to ensure easy disassembly and assembly.

Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
