Description

Technical Field

[0001] This utility model belongs to the technical field of building engineering accessories, and in particular relates to a stripping screw mountain-shaped clamp reinforcement device. Background Technology

[0002] As an important reinforcement measure for the bottom of beams and slabs on the outer side of building structures during formwork installation and concrete pouring, the stability of the reinforcement is directly related to the quality of concrete forming.

[0003] Currently, the formwork for the bottom of beams and slabs on the outer side of building structures is typically reinforced with wire tie rods. However, this method is prone to problems such as formwork bursting during concrete pouring, severely impacting concrete quality and structural safety. Using side bolts to lock and reinforce the side formwork of the frame beams results in a more stable structure, preventing formwork bulging during concrete pouring. The "mountain-shaped clips" further tighten the bolts, providing a significant fixing effect. Utility Model Content

[0004] The purpose of this utility model is to provide a stripping screw mountain-shaped clamp reinforcement device, which improves the mountain-shaped clamp structure and enhances clamping stability.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A stripping screw U-shaped clip reinforcement device includes a screw, one end of which is equipped with a U-shaped clip, and the other end is equipped with a fixing device for fixing to the template;

[0007] The mountain-shaped clamp is a shell structure, crescent-shaped, with a through hole in the center for fixing the end of the screw. On both sides of the through hole are arc-shaped grooves for engaging the steel pipes on both sides.

[0008] The mountain-shaped card has pointed ends at both ends, and an arc-shaped card is fixed at the corresponding groove position. The arc-shaped card is located in the groove, with one end extending into the groove and the other end connected to the end of the mountain-shaped card in an arc shape.

[0009] Furthermore, the inner arc surface of the arc-shaped card has anti-slip texture.

[0010] Furthermore, a limiting ring is fixed to the outer arc side of the perforation of the mountain-shaped clip, and a threaded sleeve is installed for limiting the installation. One side of the threaded sleeve has a limiting sleeve with a limiting groove for limiting the installation of the limiting ring and rotating connection. The other side of the threaded sleeve has an internal thread and a hexagonal outer side.

[0011] Furthermore, the fixing device includes a mounting plate with mounting holes at corresponding corner positions, and the end of the screw is mounted on the mounting plate. The end of the screw and the mounting plate are hinged together by a flip-type hinge. The end of the screw has a positioning block, and the mounting plate has positioning plates on both sides corresponding to the positioning blocks. The positioning blocks have hinge shafts, and the positioning plates have hinge holes for the hinge shafts to pass through and rotate.

[0012] This utility model has the following beneficial effects: The groove corresponding to the mountain-shaped card structure also has an arc-shaped card, which is used to replace the side of the groove position to contact the surface of the steel pipe, thereby increasing the contact area with the steel pipe. At the same time, the arc-shaped card is an elastic structure, and the elasticity is provided by the arc-shaped connection between the mountain-shaped card and the arc-shaped card. When the arc-shaped card contacts the steel pipe, under the pulling force of the screw, the arc-shaped card is pressed and deformed, elastically resisting the steel pipe, thereby improving the stability of the limiting engagement.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1-4As shown: A stripping screw and mountain-shaped clip reinforcement device includes a screw 1, a mountain-shaped clip 2 installed at one end of the screw 1, and a fixing device installed at the other end for fixing to the template 6;

[0022] The mountain-shaped card 2 is a shell structure, crescent-shaped, with a through hole 21 in the center for fixing the end of the screw 1. Corresponding to the through hole 21 are arc-shaped grooves 22 on both sides for engaging the steel pipes 7 on both sides.

[0023] The two ends of the mountain-shaped card 2 are pointed, and an arc-shaped card 3 is fixed at the corresponding position of the groove 22. The arc-shaped card 3 is located in the groove 22, with one end of the arc-shaped card 3 extending into the groove 22 and the other end connected to the end of the mountain-shaped card 2 in an arc shape.

[0024] During the pouring of the beam, wooden formwork is installed on both sides, and mountain-shaped clamps are used in conjunction with screws for lateral lifting to fix the lateral formwork, forming a corresponding pouring groove, and then the reinforcing cage is installed.

[0025] One end of the screw is a fixing device used to secure it to the formwork, while the other end is fitted with a U-shaped clip. This clip is positioned via a steel pipe on the back of the formwork, providing a stress point. The U-shaped clip has a groove that engages with the steel pipe to prevent it from detaching. However, the steel pipes, serving as external structural supports, have inconsistent diameters. The groove diameter of the U-shaped clip is larger than that of the steel pipe, resulting in a single contact point. Furthermore, the reinforcement device needs to be maintained with prolonged lifting while waiting for the poured concrete to dry. Therefore, the U-shaped clip is prone to loosening from the steel pipe during this process. Ultimately, this leads to gaps at the formwork joints, affecting the pouring quality.

[0026] The groove corresponding to the mountain-shaped clamp structure also has an arc-shaped clamp, which is used to replace the side of the groove position to contact the steel pipe surface, increasing the contact area with the steel pipe. At the same time, the arc-shaped clamp is an elastic structure, and the elasticity is provided by the arc-shaped connection between the mountain-shaped clamp and the arc-shaped clamp. When the arc-shaped clamp contacts the steel pipe, under the pulling force of the screw, the arc-shaped clamp is pressed and deformed, elastically resisting the steel pipe, improving the stability of the limiting clamping.

[0027] like Figure 4 As shown: The inner arc surface of the arc-shaped card 3 has anti-slip texture. This increases friction when in contact with the steel pipe.

[0028] like Figure 5 As shown: A limiting ring 23 is fixed to the outer arc side of the mountain-shaped clip 2 corresponding to the through hole 21, and a threaded sleeve 5 is installed therefore. One side of the threaded sleeve 5 has a limiting sleeve 51 with a limiting groove 52, used to limit the installation of the limiting ring 23 and for rotational connection. The other side of the threaded sleeve 5 has an internal thread, and the outer side is hexagonal. This allows the threaded sleeve to be rotated using a wrench. The threaded sleeve is fitted onto the screw rod, and the rotation of the threaded sleeve drives the mountain-shaped clip to move laterally along the screw rod axis. Simultaneously, the threaded sleeve and the limiting ring are rotatably connected and have a limiting function. As a whole, this prevents the threaded sleeve from easily falling off due to its external installation.

[0029] like Figure 3 As shown: The fixing device includes a mounting plate 4, with mounting holes 41 at corresponding corner positions. The end of the screw 1 is mounted on the mounting plate 4. The mounting plate is a rectangular steel plate structure, which is attached to the template mounting side during installation and fixed by screws corresponding to the mounting holes. The end of the screw 1 is hinged to the mounting plate 4 in a flip-type manner. The end of the screw 1 has a positioning block 11, and the mounting plate 4 has positioning plates 42 on both sides corresponding to the positioning block 11. The positioning block has a hinge shaft, and the positioning plate 42 has a hinge hole for the hinge shaft to pass through and rotate. This allows the positioning end of the screw corresponding to the mounting plate to have a flip-adjustment function, preventing the other end of the screw from deviating from the template penetration point. By adjusting the screw up and down by a small angle, the template penetration position can be shifted to achieve the best lifting effect.

[0030] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
