Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a device for controlling and measuring the thickness of a cast-in-place concrete floor slab. Background Art

[0002] When building floor slabs, many projects will adopt the cast-in-place method for construction. In order to ensure strength and stability, the thickness of the floor slab needs to be accurately controlled when pouring the floor slab. The current method of controlling the thickness of the floor slab is to first calculate according to the elevation, then reversely measure to determine the elevation of the top of the slab, and then use a line, infrared, and a level to determine the elevation. For example, when pouring a concrete floor slab, it is generally placed on the column reinforcement at the floor elevation, and a line is pulled from the column elevation, or the thickness of the slab around the column is directly measured. The thickness of the remaining slabs is difficult to control in place, and the column reinforcement with elevation marks is easily touched by humans or machines, resulting in inaccurate elevations. It is also easy to cause problems such as inadequate briefing, lazy workers, and weak execution, resulting in errors in the thickness of the floor slab. After the pouring is completed, the current measurement of the thickness of the floor slab is mainly done by drilling, which not only destroys the integrity of the floor slab and easily leads to the risk of leakage in the later stage, but also requires the cooperation of multiple people and multiple tools, which is very cumbersome. Utility Model Content

[0023] Example 1

[0024] See also Figures 1 to 4The utility model provides a device for controlling and measuring the thickness of cast-in-place concrete floor slabs, including a support 1, a connecting rod 2, a rotating measuring cylinder 3, a connecting cylinder 4, a template 5, and floor slab concrete 6. The support 1 is bolted to the template 5, a limit block 201 is provided at the upper end of the connecting rod 2, the lower end of the connecting rod 2 is plugged into the support 1, and the lower end of the connecting cylinder 4 is seamlessly plugged into the limit block 201. The rotating measuring cylinder 3 is threadedly connected to the upper end of the connecting cylinder 4 to enter and exit the connecting cylinder 4. The connecting cylinder 4 is provided with a scale 403 for measuring the thickness of the plate. After the top plate support is completed and the top plate elevation and horizontality are checked, the new device can be installed and fixed on the top plate, and can be fixed at the four corners and the center position of the top plate to achieve better effects and more precise control.

[0025] Specifically, the connecting tube 4 also includes a third groove 402 and a threaded hole 401. The connecting tube 4 is seamlessly plugged into the limit block 201 on the connecting rod 2 through the groove. The connecting tube 4 is connected to the rotating measuring tube 3 through the threaded hole 401. The seamless plugging is mainly to prevent concrete from entering the third groove.

[0026] Specifically, the connecting tube 4 is a cylinder, and the outside of the connecting tube 4 is coated with a release agent that is easily separated from the floor concrete 6. The release agent can be mineral oil, synthetic oil, dimethyl silicone oil, etc. The release agent is mainly used to facilitate the removal of the connecting tube after the concrete is formed and strengthened, and it can be recycled and reused again.

[0027] Specifically, the rotating measuring cylinder 3 includes a cylinder body, a threaded rod 301 arranged at the center of the cylinder body, a second groove 302, and a measuring disk 303. The cylinder body is provided with a second groove 302 that runs through the bottom of the cylinder body. The threaded rod 301 is arranged inside the second groove 302. The threaded rod 301 enters and exits the third groove 402 through a threaded hole 401. The measuring disk 303 protrudes from the outside of the connecting cylinder 4. The length of the screw rod entering and exiting the connecting cylinder is adjusted according to the specific plate thickness. The distance between the measuring disk and the template is the thickness of the cast plate.

[0028] Specifically, the measuring disk 303 is a metal disk.

[0029] Specifically, the support 1 includes a first chassis 101 and a second chassis 102. The first chassis 101 is provided with a bolt hole 1011. The first chassis 101 is bolted to the template 5 through the bolt hole 1011. The first chassis 101 is fixedly connected to the second chassis 102. The second chassis 102 is provided with a first groove 1021. The lower end of the connecting rod 2 is plugged into the second chassis 102 through the first groove 1021.

[0030] Specifically, the first chassis 101 and the second chassis 102 are made of rubber. The sizes of the first chassis and the second chassis should not be too large, and the diameter is preferably 2-5CM to ensure stability. In this way, it is easier to repair the top plate after demolding to ensure the stability of the top plate. Rubber is not easy to bond with concrete, so it is easier to remove and can be reused.

[0031] When the utility model is used, after the reinforcement of the formwork 5 is completed, the support 1 is first placed on the corresponding position of the formwork 5, and the support 1 is fixed with bolts through the bolt holes 1011, and the connecting rod 2 is inserted into the first groove 1021 in the second chassis 102, and then the connecting tube 4 is inserted into the limit block 201 on the connecting rod 2, and then the release agent is evenly applied to the circumference of the connecting tube 4, and then according to the specific plate thickness, the measuring tube 3 is rotated to make the measuring disk 303 reach the corresponding scale on the scale 402. When pouring the floor slab concrete 6, the pouring situation can be intuitively observed according to the position of the measuring disk 303, so as to better control the pouring thickness. After the pouring is completed, the bolts are removed and the connecting tube 4 is taken down for turnover.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
