DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 5As shown, a side formwork fixing device for highway water-stabilized construction includes an inclined tie rod 1, an anchor 2 and a formwork side connection structure 3. One end of the inclined tie rod 1 is provided with a sleeve portion 1.1 for sleeved on the outside of the anchor 2, and the other end of the inclined tie rod 1 is provided with a through portion 1.2 for passing through the side formwork. The anchor 2 is used to fix the sleeve portion 1.1 on the ground, and the formwork side connection structure 3 is used to connect the through portion 1.2 through one end of the side formwork to limit the formwork from the outside. In the highway water-stabilized construction, the inclined tie rod 1 connects the anchor 2 and the side formwork, and the side formwork is fixed by inserting the anchor 2 into the roadbed. The sleeve portion 1.1 is sleeved on the outside of the anchor 2, so that the inclined tie rod 1 can be connected to the roadbed through the anchor 2 to provide stable support for the side formwork. The through portion 1.2 is provided so that the inclined tie rod 1 can pass through the side formwork and connect to the outer side of the side formwork. The formwork side connection structure 3 cooperates with the through portion 1.2 to limit the side formwork from the outside.

[0023] The sleeve portion 1.1 is formed by bending the end of the inclined tie rod 1. The sleeve portion 1.1 is formed by bending the end of the inclined tie rod 1, which simplifies the structure and is convenient for sleeve installation outside the anchor 2 to achieve stable connection.

[0024] The penetration part 1.2 is a straight rod-shaped structure, and a thread is arranged on the penetration part 1.2. The template side connection structure 3 includes a nut 3.1 threadedly connected to the penetration part 1.2. The penetration part 1.2 is designed as a straight rod-shaped structure to facilitate the penetration of the side template. The nut 3.1 cooperates with the thread on the penetration part 1.2 to achieve stable support for the template.

[0025] The template side connection structure 3 includes an outer limit plate 3.2, which is used to be pressed on the outer side of the side template by the nut 3.1. The two side templates are connected and fixed by setting the outer limit plate 3.2 to prevent the two side templates from separating. At the same time, it is supported on the outer side of the template to prevent the template from tilting. The outer limit plate 3.2 is pressed on the side template by the nut 3.1, further improving the stability of the side template and preventing displacement during construction, which affects the construction quality.

[0026] The side template is provided with a through hole for the through portion 1.2 to pass through, and the template side connection structure 3 includes an inner limit plate 4 fixedly installed in the through hole, an arc-shaped inner clamping plate 5 is fixedly provided on one side of the center of the outer side surface of the inner limit plate 4, and an outer clamping plate 6 for sleeved on the inner clamping plate 5 is provided on the inner side surface of the outer limit plate 3.2. The through hole is provided to provide a passage for the through portion 1.2, and the inner clamping plate 5 and the outer clamping plate 6 are clamped together, so that the outer limit plate 3.2 can be tightly clamped on the inner limit plate 4.

[0027] The outer side of the inner card plate 5 is provided with a card slot 7, and the inner surface of the outer card plate 6 is provided with a card connection portion 8 that matches the card slot 7 at one end facing the side template, and the card connection portion 8 can enter the card slot 7 by rotation. By rotating the outer limit plate 3.2, the card connection portion 8 is engaged with the card slot 7 of the inner card plate 5, and the two side templates are fixed, which facilitates the splicing of the two side templates.

[0028] The outer limit plate 3.2 has a longitudinally distributed through groove 9 inside, and a slider 10 capable of longitudinal displacement is arranged inside the through groove 9. Both upper and lower ends of the slider 10 are provided with force storage springs 11, and the slider 10 has a through hole for the penetration portion 1.2 to pass through. When the anchor 2 is inserted into the cement stabilized gravel base, the slider 10 moves downward in the through groove 9, and the force storage spring 11 provides a stroke for the anchor 2 to descend. At the same time, the force storage spring 11 has a buffering effect to reduce the vibration of the side formwork, and by compressing the spring downward, the side formwork is pressed against the cement stabilized gravel base. The through hole is provided so that the penetration portion 1.2 can pass through the slider 10 to connect the nut 3.1.

[0029] The through slot 9 is located within the circumference of the perforation, and the through portion 1.2 is threadedly connected with an inner baffle 12 located on the inner side of the template. The inner baffle 12 is used to closely adhere to the inner surface of the side template to block the inner end of the perforation. The through slot 9 is located within the circumference of the perforation, which helps to keep the slider 10 stable during movement. The perforation is blocked by the inner baffle 12 to prevent cement or gravel from entering the perforation. At the same time, it is attached to the inner side of the side template and cooperates with the outer limit plate 3.2 to support the template from both sides to ensure the verticality of the template.

[0030] Place the two side templates at the measured positions, insert the inclined tie rod 1 from the outside of the template into the through hole, so that the through part 1.2 is located in the through hole. Place the outer limit plate 3.2 on the outside of the side template and put it on the outside of the inner limit plate 4. By rotating the outer limit plate 3.2, the clamping part 8 on the outer clamping plate 6 is clamped into the clamping groove 7 of the inner clamping plate 5, and the inner limit plate 4 and the outer limit plate 3.2 are connected. Then rotate the nut 3.1 on the through part 1.2 so that the outer limit plate 3.2 is squeezed on the outer surface of the side template by the nut 3.1, and the two side templates are connected and fixed. The inner baffle 12 is tightly attached to the inner surface of the side template to cover the inner end of the through hole, and the outer limit plate 3.2 supports the side template from both sides to prevent the side template from displacement during construction. The sleeve portion 1.1 of the inclined tie rod 1 is sleeved on the outside of the anchor 2, and the anchor 2 is driven into the roadbed. During this process, the inclined tie rod 1 drives the slider 10 to move downward in the through groove 9. Under the buffering effect of the force storage spring 11, the vibration of the side formwork is reduced, and the side formwork is pressed tightly on the roadbed, completing the fixing operation of the side formwork of the highway water-stabilized construction, and the highway cement stable paving construction can be carried out.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
