Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of floor construction, and in particular relates to a concrete floor thickness control device and method. BACKGROUND

[0002] In the construction of the main structure, the floor thickness has always been the focus of quality control, and is more related to the safety of the overall structure. During the construction process, due to the excessive span of the floor, the thickness of the floor around the floor may meet the requirements, and a low area may be formed in the middle of the floor, which may eventually affect the cumulative difference of the floor to exceed the specification requirements, and may even cause a quality accident. In the past, a ruler or embedded steel bars have been used to control the thickness of the floor. However, such methods have poor feasibility in actual operation and may easily cause the formation of concrete surfaces with poor quality.

[0003] For example, Chinese Patent Publication No. CN111236655A discloses a floor thickness control tool. The locking nut A at the upper end of the inverted table-shaped fixing member is screwed along the lower end of the fixed screw until the locking nut A at the upper end of the inverted table-shaped fixing member is screwed over the lower end of the fixed screw, and then the inverted table-shaped fixing member is lifted. However, when disassembling, force needs to be applied from the bottom to the top, which is inconsistent with the conventional construction operation, which usually tends to apply force from the top to the bottom. Moreover, applying force from the bottom to the top may cause the tool to slide and cause harm to the operator. For example, Chinese Patent Publication No. CN110145126B discloses a floor thickness control pad, which includes a base, a contraction positioning structure, and an indicating column. The base is provided with a mounting groove and a first positioning groove. The mounting groove extends in the vertical direction, and the cross section of the mounting groove is the same in shape and size as the cross section of the indicating column. However, the base is not fixed in position, and may be displaced during the pouring of the floor, which may result in inaccurate positioning of the indicating column and affect the control of the floor thickness. Therefore, a concrete floor thickness control device and method that is more stable in controlling the floor thickness are designed. SUMMARY
