Description

Formwork clamps for building construction

Technical Field

The utility model belongs to the technical field of building construction equipment, and in particular relates to a template clamp for building construction.

Background Art

When pouring concrete, a large number of templates are needed to form a concrete pouring cavity, such as square columns, beams, wall panels, etc. When pouring concrete through the template to form a pouring cavity, a clamp is generally needed to fix the template. The clamp can effectively prevent the template from being deformed, cracked, etc. when pouring concrete. For example, patent publication number CN216276915U, a patent named a building beam mold clamp, discloses a beam clamp. The beam clamp disclosed in the above patent and the common beam clamps in the market have the disadvantage of being inconvenient for early installation when used. During installation, workers are generally required to first insert the two-side beam clamps upward into the two sides of the beam template, that is, the beam template is between the two side clamps, and then clamp the two side clamps. During the clamping process, the worker needs to drag the clamp upward with his hand while clamping. When clamping, not only is the clamp prone to tipping over, but the worker's labor intensity is also high, and the template clamping efficiency is low, especially for a clamp with a larger width. Moreover, when installing beam clamps on the beam formwork, it is often necessary to install one at a certain distance, for example, a beam clamp can be installed every 50 centimeters. Currently, workers generally install them after visually measuring the distance, and they are also installed by lifting upwards, so that the distance between two adjacent beam clamps is not standardized.

Summary of the invention

The utility model aims to provide a template clamp for construction, so as to overcome the defects of the prior art that the beam template clamp needs workers to hold it upward with their hands when clamping, which is easy to tip over, the labor intensity of workers is high, and the distance between two adjacent beam templates is not standardized.

The utility model is implemented by adopting the following technical scheme: a template clamp for construction, comprising a mother rod, a first telescopic cavity is provided on the mother rod, a child rod is inserted into the first telescopic cavity, a second telescopic cavity is provided on the child rod, a screw rod is rotatably installed in the first telescopic cavity of the mother rod, one end of the screw rod extends out of the mother rod and is installed with a screw rod head, the other end of the screw rod is inserted into the second telescopic cavity of the child rod, a child rod threaded hole matching with the screw rod is provided at one end of the child rod close to the mother rod, a movable clamp is installed at the other end of the child rod, and a fixed clamp is installed at one end of the mother rod close to the screw rod head; a support rod is detachably installed at the bottom of the mother rod, the support rod is vertically arranged with the mother rod, and a sleeve is provided at one end of the mother rod.

Furthermore, a support block is installed at the bottom of the mother rod, a support threaded hole is provided on the support block, and an external thread matching with the support threaded hole is provided in the middle of the support rod.

Furthermore, two support rods are detachably mounted on the bottom of the mother rod.

Furthermore, a distance scale is provided on the top surface of the sub-rod.

Furthermore, the length of the support rod is 50-80 cm.

Furthermore, a bearing seat is installed in the first telescopic cavity of the female rod, a bearing is installed in the bearing seat, and the screw rod passes through the bearing and is fixedly connected to the inner ring of the bearing.

Furthermore, a through hole is provided on the screw rod head; and an internal thread is provided in the through hole.

Furthermore, the movable clamping plate and the fixed clamping plate both include vertical plates, and diagonal support plates are respectively installed on both sides of the vertical plates.

Compared with the prior art, the beneficial effects of the utility model are:

1. The utility model installs a support rod at the bottom of the mother rod, and the support rod can play the role of temporarily supporting adjacent beam clamps. When installing the rotating screw rod, workers do not need to lift the beam clamp with force while rotating the screw rod, which not only reduces the labor intensity of workers but also makes the installation more standardized. The distance between two adjacent beam clamps is limited by the length of the support rod, so that when the beam clamps are installed, the clamps between two adjacent beam templates can be kept at a certain distance.

2. The utility model makes it more convenient to clamp the beam formwork, and the clamping is more secure. When clamping, the worker only needs to rotate the screw head through a tool such as an electric screwdriver, and rotate the screw through the screw head. When the screw rotates, the sub-rod is driven to extend and retract along the first telescopic cavity of the mother rod through the sub-rod threaded hole, and the sub-rod drives the movable clamp thereon to extend and retract to achieve clamping and loosening.

Installation process of this utility model:

During installation, we can first install one of the beam clamps on the beam template. After the beam clamp clamps the beam template, the support rod 10 is threadedly connected to the support threaded hole 13 on the beam clamp.

Then, when installing the adjacent beam clamps, first install the support rod 10 into the support threaded hole 13 of the adjacent beam clamp, and then lift the adjacent beam clamp so that the beam template is between the movable clamp 8 and the fixed clamp 9 of the adjacent beam clamp, and then insert one end of the support rod 10 on the adjacent beam clamp into the sleeve 11 on the support rod 10 on the fixed beam clamp. The fixed beam clamp can serve the purpose of temporarily supporting the adjacent beam clamp. In this way, when the worker rotates the screw 5, he does not need to lift the beam clamp with force, but only needs to hold the beam clamp with his hand, and the support rod 10 can be used to determine the distance between the two adjacent beam clamps.
