[0002] In the construction of buildings, the control of the floor slab thickness has always been a key point in the industry. Excessive thickness will increase the load and affect the finishing surface layer at the same time. Too thin will cause insufficient bearing capacity of the floor slab and pose a danger. Therefore, the control of the steel bar protection layer thickness is an important inspection part of the steel bar installation, and the slab thickness is a key inspection item for concrete acceptance. During the acceptance of the main structure, it is necessary to measure the slab thickness by drilling holes on the slab surface. Affected by the randomness of the drilling position, it is difficult to ensure that the slab thickness at the drilling position completely meets the expectations. How to control the concrete slab thickness, the steel bar protection layer thickness and make the detection more convenient is the key point to be solved at present.

[0003] When setting the hole former in the upper and lower layers of steel bar meshes, the positioning is often inaccurate, it is easy to slide, and it is difficult to ensure the concrete thickness outside the two layers of steel bars at the same time. Content of the Utility Model

When placing the hole - leaving device, the upper - layer steel bars in the steel bar mesh are placed on the side - supporting member 201, and the side - supporting member 201 is fixed to the upper - layer steel bars with the binding member 202. The distance from the side - supporting member 201 to the top of the hole - leaving component 100 is used to control the thickness of the concrete protective layer outside the upper - layer steel bars. And, a bottom supporting component 300, which includes a bottom - supporting member 301 arranged at the bottom of the hole - leaving component 100 and a fixing member 302 arranged on the top of the bottom - supporting member 301. When placing the hole - leaving device, the lower - layer steel bars in the steel bar mesh are placed on the bottom - supporting member 301, and the bottom - supporting member 301 is fixed to the lower - layer steel bars with the fixing member 302. The distance from the bottom - supporting member 301 to the bottom of the hole - leaving component 100 is used to control the thickness of the concrete protective layer outside the lower - layer steel bars. The hole - leaving device is fixed by the upper supporting component 200 and the bottom supporting component 300 using the steel bar mesh, preventing the hole - leaving device from shifting during the pouring process and simultaneously controlling the thickness of the concrete outside the steel bar mesh, which is convenient for subsequent detection and acceptance.

[0025] Usage process: When placing the hole - leaving device, the upper - layer steel bars in the steel bar mesh are placed on the side - supporting member 201, and the side - supporting member 201 is fixed to the upper - layer steel bars with the binding member 202. The lower - layer steel bars in the steel bar mesh are placed on the bottom - supporting member 301, and the bottom - supporting member 301 is fixed to the lower - layer steel bars with the fixing member 302. The hole - leaving device is fixed by the upper supporting component 200 and the bottom supporting component 300 using the steel bar mesh.

[0026] Embodiment 2, referring to Figures 1 to 2 , which is the second embodiment of the present utility model. Different from the previous embodiment, the hole - leaving component 100 includes a central cylinder 101, and a cover plate 102 is arranged at the top of the central cylinder 101.

[0027] Furthermore, the side - supporting member 201 includes a side - supporting plate 201a arranged on the outer wall of the central cylinder 101. An arc - shaped supporting surface 201b is opened at the top of the side - supporting plate 201a, and the upper - layer steel bars are placed on the arc - shaped supporting surface 201b for convenient fixing.

[0028] Further, a pressure bar 201c is provided at the top of the side support plate 201a. A through groove is formed between the bottom of the pressure bar 201c and the top of the side support plate 201a. Wedge-shaped teeth 201d are provided at the bottom of the pressure bar 201c. The binding member 202 includes a binding strip 202a provided at the top of the side support plate 201a. The binding strip 202a can be inserted into the through groove formed between the bottom of the pressure bar 201c and the top of the side support plate 201a. Wedge-shaped locking teeth 202b are provided at the top of the binding strip 202a. The binding strip 202a is made of an elastic material. When the arc-shaped support surface 201b at the top of the side support plate 201a abuts against the upper layer of steel bars, the binding strip 202a is pulled open and inserted into the through groove, and then the binding strip 202a is tightened. The wedge-shaped locking teeth 202b will engage with the wedge-shaped teeth 201d at the bottom of the through groove until the binding strip 202a binds the steel bars tightly, completing the fixation of the side support member 201 and the upper layer of steel bars.

[0029] During use: When the arc-shaped support surface 201b at the top of the side support plate 201a abuts against the upper layer of steel bars, the binding strip 202a is pulled open and inserted into the through groove, and then the binding strip 202a is tightened. The wedge-shaped locking teeth 202b will engage with the wedge-shaped teeth 201d at the bottom of the through groove until the binding strip 202a binds the steel bars tightly, completing the fixation of the side support member 201 and the upper layer of steel bars.

[0030] Example 3, referring to Figures 1 to 3 , which is the third embodiment of the present utility model. Different from the previous embodiment, the bottom support member 301 includes a bottom plate 301a provided at the bottom of the central cylinder 101. A bottom support plate 301b is provided at the top of the bottom plate 301a. An arc-shaped surface 301c is formed on the top of the bottom support plate 301b.

An inclined plate 302d is disposed on the side of the plug 302c. The material of the inclined plate 302d is an elastic material. When the arc surface 301c at the top of the bottom support plate 301b abuts against the lower-layer steel bars, the sliding ring 302a is slid down, and the plug 302c at the bottom of the support rod 302b is inserted into the receiving groove 301d of the bottom support plate 301b. During the insertion into the receiving groove 301d, the inclined plate 302d will be squeezed by the inner wall of the receiving groove 301d and forced to approach the plug 302c until the plug 302c is completely inserted into the receiving groove 301d. The inclined plate 302d will rebound into the wedge-shaped card slot 301e, and the inclined plate 302d will abut against the top of the wedge-shaped card slot 301e. At this time, the plug 302c cannot slide out of the receiving groove 301d, and the fixation of the bottom support member 301 and the lower-layer steel bars is completed.

[0032] Usage process: When the arc surface 301c at the top of the bottom support plate 301b abuts against the lower-layer steel bars, the sliding ring 302a is slid down, and the plug 302c at the bottom of the support rod 302b is inserted into the receiving groove 301d of the bottom support plate 301b. During the insertion into the receiving groove 301d, the inclined plate 302d will be squeezed by the inner wall of the receiving groove 301d and forced to approach the plug 302c until the plug 302c is completely inserted into the receiving groove 301d. The inclined plate 302d will rebound into the wedge-shaped card slot 301e, and the inclined plate 302d will abut against the top of the wedge-shaped card slot 301e. At this time, the plug 302c cannot slide out of the receiving groove 301d, and the fixation of the bottom support member 301 and the lower-layer steel bars is completed.
