Specific embodiments

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Therefore, the following detailed description of the embodiments of the present utility model provided in the drawings is not intended to limit the scope of the claimed present utility model, but merely represents selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-3As shown in the figure, the utility model provides an inner support device for a pile foundation steel reinforcement cage with adjustable size, which includes an arc-shaped plate 10 and adjustable struts 20. Two hinge seats 12 are arranged on the inner arc surface of the arc-shaped plate 10. There are three arc-shaped plates 10, which are arranged in a triangular shape inside the steel reinforcement cage. The adjustable strut 20 includes a first strut 21 and a second strut 22. One end of the first strut 21 is provided with a threaded rod 2101, and one end of the second strut 22 is provided with a docking head 2201. An activity groove 2203 is opened at the end of the docking head 2201. A rotary handle 23 is movably arranged on the docking head 2201. The threaded rod 2101 is threadedly connected with the rotary handle 23, and one end of the threaded rod 2101 is movably arranged inside the activity groove 2203. There are three adjustable struts 20, and both ends of each adjustable strut 20 are respectively hinged to the adjacent hinge seats 12 on the adjacent arc-shaped plates 10. When the support device is placed inside the steel reinforcement cage, the length of the adjustable strut 20 can be adjusted respectively by rotating the handle, so that the three arc-shaped plates 10 form a contact support effect with the inner side of the steel reinforcement cage. The disassembly and assembly of the support device do not require additional tools and can be disassembled and assembled by itself. Moreover, the method of adjusting the size of the support device by rotating the rotary handle 23 can be applied to the steel reinforcement cage sizes of various specifications, which is convenient for transportation and use.

[0023] As a preferred embodiment, an inner groove 11 is opened on the outer arc surface of the arc-shaped plate 10. The inner groove 11 helps to fix the support device on the main bars inside the steel reinforcement cage, ensuring that the three arc-shaped plates 10 of the support device and the main bars inside the steel reinforcement cage are in the same plane, improving the stability of the support. A rubber pad is arranged in the inner groove 11. Since the support device has a size adjustment function and the radian of the arc-shaped plate 10 is in a fixed state, after adjusting the length of the adjustable strut 20, it is impossible to keep the radian of the main bars inside the steel reinforcement cage the same as that of the arc-shaped plate 10 to make them completely fit. By setting the rubber pad, the contact area between the main bar and the arc-shaped plate 10 can be increased, so as to better support it. Further, the rubber pad can also reduce the collision and wear between the arc-shaped plate 10 and the main bars of the steel reinforcement cage during long-term use, and prolong the service life of the device.

[0024] As Figure 4As shown in the figure, a docking groove 2301 is provided at one end of the rotating handle 23, and an internal threaded hole 2303 penetrating through to the docking groove 2301 is provided at the center of the other end thereof. The threaded rod 2101 is threadedly connected to the internal threaded hole 2303. A plurality of limiting side grooves 2302 are provided on the side wall of the docking groove 2301. After the docking head 2201 is inserted into the docking groove 2301, a limiting flange 2202 engaged with the limiting side grooves 2302 is provided on the outside thereof. The rotating handle 23 and the second support rod 22 form a rotating connection relationship. By manually rotating the rotating handle 23, it spirally moves on the threaded rod 2101, so that the first support rod 21 and the second support rod 22 approach or separate from each other, thereby adjusting the length of the adjustable support rod 20. A limiting piece 2104 is provided at the end of the threaded rod 2101. When the adjustable support rod 20 is adjusted to the longest, the limiting piece 2104 abuts against the bottom wall of the docking groove 2301 to prevent the second support rod 22 from disconnecting from the first support rod 21.

[0025] As Figure 3 shown in the figure, a side plane 21,02 is provided on one side of the threaded rod 2101, and scale lines 2103 are provided on the side plane 2102. A reading baffle 2304 is provided at the end of the rotating handle 23 away from the docking groove 2301. The scale lines 2103 help construction workers to clarify the length adjustment of the three adjustable support rods 20, and further judge the contact situation between the three arc-shaped plates 10 and the main bars on the inner side of the steel reinforcement cage, while the reading baffle 2304 helps construction workers to take readings.

[0026] As a preferred embodiment, an anti-slip layer is provided on the outside of the rotating handle 23. The anti-slip layer is a rubber convex rib arranged in a circumferential array on the outside of the rotating handle 23. The anti-slip layer increases the friction and comfort of construction workers holding the rotating handle 23.

[0027] Specifically, the working principle of the size-adjustable internal support device for the pile foundation steel reinforcement cage: Place the support device on one of the main bars on the inner side of the steel reinforcement cage, and rotate the rotating handle 23 respectively to make it move on the threaded rod 2101, so that the second support rod 22 moves away from the first support rod 21. At this time, the main bar forms a contact relationship with the inner grooves 11 on the three arc-shaped plates 10. A plurality of the support devices are provided and arranged at a certain interval on the inner side of the steel reinforcement cage, and the support of the steel reinforcement cage can be completed. Through the above structure, the problems that the existing internal support structure of the steel reinforcement cage has a fixed size, is inconvenient to adjust, and is difficult to meet the requirements of steel reinforcement cages with different diameters and heights are solved. This not only increases the construction difficulty, but also limits the versatility and flexibility of the steel reinforcement cage.

[0028] The above has further described the present utility model with reference to specific embodiments. However, it should be understood that this specific description should not be construed as a limitation on the essence and scope of the present utility model. Various modifications made by those of ordinary skill in the art to the above embodiments after reading this specification all fall within the scope protected by the present utility model.
