Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building engineering template reinforcement, in particular to a template limiting device for controlling the thickness of a cast-in-place concrete wall. Background Art
[0002] During the construction of cast-in-place concrete walls, a large number of formworks are required to assist in forming. When installing and fixing the formworks, screws are usually used to tie and tighten the formworks to ensure that the formworks have sufficient stability and overall rigidity to withstand the lateral pressure and other loads of the concrete.
[0003] However, the use of screws can only control the formwork from deflecting outward. In order to ensure the accuracy of the thickness of the concrete wall casting, the formwork is reinforced and the formwork is controlled to prevent it from deflecting inward of the wall during casting. The existing technology usually uses precast concrete strips. However, the concrete strips are not easy to place perpendicular to the formwork, and when the formwork height is high, it is difficult to place the strips evenly. When pouring concrete, the concrete strips are easily impacted and fall off. In addition, different lengths of concrete strips are required for different wall thicknesses, which is inconvenient to use. Utility Model Content

The two locking buckles on the tension bolt clamp the template through the template reinforcement. The sleeve is sleeved on the screw rod. The internal support includes a wire drum, a first nut for supporting the template, and a second nut for tightening the first nut. The wire drum is sleeved on the sleeve, and the first nut and the second nut are both threadedly connected to the wire drum.
[0006] Preferably, two first nuts are provided, the first nuts comprising a first nut body and a support leg for supporting the template, the support leg being fixedly connected to the first nut body, and the second nut being provided between the first nut and the template.
