Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a shear wall column steel bar and concrete protective layer positioner. Background Art
[0002] Shear wall columns are part of a building's frame-shear structure. They are typically constructed of reinforced concrete, increasing the structure's strength and collapse resistance. In some locations, reinforced concrete shear walls can be cast in-situ or prefabricated. During construction, to prevent exposed steel reinforcement, the steel must be encased in concrete, ensuring the required protective thickness of the shear wall column reinforcement and outer concrete.
[0003] Different construction conditions require different thicknesses of the protective layer. Existing protective layer locators are generally plastic clips and cement pads. (1) When using plastic clips, the corresponding type of plastic clips can be clamped on the outside of the shear wall column transverse reinforcement. However, the plastic clips themselves are prone to falling off and damage under external force interference. At the same time, problems such as tilting may occur when they are clamped on the shear wall column transverse reinforcement. (2) Cement pads are hung on the surface of the shear wall column transverse reinforcement. Under external force interference, they are prone to displacement and damage. These problems may lead to large errors between the shear wall column reinforcement and the outer concrete protective layer. For this reason, we propose a shear wall column reinforcement and concrete protective layer locator. Utility Model Content
[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a shear wall column steel bar and concrete protective layer locator, which can be tightly clamped on the outside of the main reinforcement and the shear wall column transverse reinforcement without shaking, and can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a shear wall column steel bar and concrete cover locator, comprising a main bar outer clamp and a main bar inner clamp;
[0006] Main reinforcement outer clamp: a telescopic nut baffle is provided at its front end, and an arc-shaped groove is provided on the inner side of the rear end, and the arc-shaped groove protrudes from the outside of the main reinforcement outer clamp;
[0007] The clamp inside the main reinforcement: there is a fixed connecting sleeve on its rear side, and the internal spiral connection of the sleeve is connected to the adjusting screw. The rear end of the adjusting screw passes through the middle of the telescopic nut baffle and is threadedly connected to the telescopic nut baffle. The front end of the adjusting screw passes through the sleeve and the middle of the clamp inside the main reinforcement in turn and is connected to the clamp inside the main reinforcement by a movably connected process. By rotating the adjusting screw to adjust the tightness, it can be tightly clamped on the outside of the main reinforcement and the transverse reinforcement of the shear wall column without shaking.
[0008] Furthermore, the lower end of the main reinforcement inner clamp is provided with a left-right symmetrical fixed half-moon clamp, which is used to be fixed on the transverse reinforcement of the shear wall column.
[0009] Furthermore, it also includes an arc-shaped positioning rib, which is connected and fixed between the front side surfaces of the two half-moon clips to enhance the mechanical strength.
[0010] Furthermore, the front end of the main reinforcement outer clamp is provided with left-right symmetrically distributed slots, the telescopic nut baffle is clamped between the two slots, and the telescopic nut baffle is installed.
[0011] Furthermore, both left and right sides of the main reinforcement inner clamp are bent forward, and the main reinforcement inner clamp is inclined toward the arc position of the main reinforcement outer clamp, so that the main reinforcement inner clamp is tightly clamped on the outside of the main reinforcement.
[0012] Furthermore, a slot is provided at the tail end of the adjusting screw to facilitate adjustment.
[0013] Compared with the prior art, the beneficial effects of the present invention are: the shear wall column steel bar and concrete cover locator has the following advantages:
[0014] According to the design requirements, select the inner and outer clamps of the corresponding models for the main reinforcement and transverse reinforcement of the shear wall column, and put the inner and outer clamps of the main reinforcement on the outside of the main reinforcement. The main reinforcement is located between the outer clamp of the main reinforcement and the inner clamp of the main reinforcement. The shear wall column transverse reinforcement fixing half-moon clamp is fixed to the corresponding position of the shear wall column transverse reinforcement. Turn the adjusting screw to adjust the tightness between the outer clamp of the main reinforcement and the inner clamp of the main reinforcement to achieve the fixation of the outer clamp of the main reinforcement and the inner clamp of the main reinforcement to the main reinforcement and transverse reinforcement of the shear wall column. The distance between the tail end of the arc-shaped positioning reinforcement and the surface of the shear wall column transverse reinforcement is the design thickness of the protective layer.
