Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a clamp used for template construction. Background Art

[0002] In the current construction industry, "Bubujin" is a new type of construction tool. It is quick to use, not only can it save working time and improve work efficiency, but also can save a lot of wood, replacing the traditional wire bundling method, the tension screw reinforcement method, and the ring plugging method. "Bubujin" is widely used as a fastener for building formwork support. However, most of the "Bubujin" on the market are easily damaged when the movable clamp is hit with a small hammer. They are easy to deform and not firm enough when used. On the one hand, it wastes materials, and on the other hand, it also brings certain inconveniences to the construction workers. Utility Model Content

[0003] In view of the problems existing in the above-mentioned prior art, the utility model provides a clamp for template construction, which can effectively solve the problems existing in the above-mentioned prior art.

[0004] The technical solution of the utility model is:

[0005] According to one aspect of the utility model, the utility model comprises: a first clamp and a second clamp, wherein the first clamp is fixedly provided with a sleeve, and the second clamp is fixedly provided with a movable rod; the movable rod can be movably inserted into the sleeve to enable the second clamp to move away from and / or approach the first clamp;

[0006] It also includes a screw rod, one end of which is threadedly connected to the movable rod, and the other end of which extends to the outside of the sleeve along the length direction of the sleeve and is fixed with a nut for abutting the sleeve.

[0007] Furthermore, a through hole is provided at one end of the sleeve, the screw rod is passed through the through hole, and a gap is formed between the through hole and the screw rod.

[0008] Furthermore, a cavity is provided inside the movable rod, and the screw rod moves horizontally in the cavity; a connecting piece is fixedly provided at one end of the movable rod, and the screw rod is threadedly connected to the connecting piece.

[0009] Furthermore, a first inclined surface inclined inwardly is arranged on the outer side of the first clamping head.

[0010] Furthermore, a second inclined surface inclined inwardly is arranged on the outer side of the second clamping head.

[0011] Furthermore, the nut is used to connect a screwdriver, a wrench or an electric tool.

[0012] Furthermore, the connecting piece is a nut.

[0013] By adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0014] This solution drives the screw to rotate in the movable rod by rotating the nut, causing the second clamp to approach the first clamp until the nut abuts against the movable rod, thereby locking the template. Construction personnel can control the movement and locking force of the second clamp to ensure the clamping accuracy and stability of the building template, which helps to avoid damage or deformation of the template due to uneven or excessive clamping force. Compared with the traditional hammer striking method, noise and vibration are generated when the hammer strikes the movable clamp, causing interference to construction personnel and the surrounding environment. Driving the second clamp by the screw reduces such noise and vibration; and can reduce the risk of safety accidents caused by improper manual operation. For example, damage to the template or personal injury caused by excessive hammer striking can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is particularly noted that the following embodiments are only used to illustrate the present invention, but do not limit the scope of the present invention. Similarly, the following embodiments are only partial embodiments of the present invention rather than all embodiments. 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 4 As shown, this solution provides a fixture for template construction.

[0023] See also Figures 1 to 3 , comprising: a first clamp 11 and a second clamp 21, the opposite surfaces of the first clamp 11 and the second clamp 21 are parallel to each other. The first clamp 11 is fixed with a sleeve 1, and the second clamp 21 is fixed with a movable rod 2; the movable rod 2 can be movably inserted into the sleeve 1, and a movable cavity 13 is arranged in the sleeve 1. The movable rod 2 moves horizontally in the movable cavity 13, so that the second clamp 21 can move away from and / or approach the first clamp 11; specifically, a through hole 12 is arranged at one end of the sleeve 1, and a screw rod 3 is passed through the through hole 12, and a gap is formed between the through hole 12 and the screw rod 3.
