Problems solved by technology

[0004] The object of the present invention is to provide a kind of cover thickness control tool that is easy to operate, to solve the traditional technology proposed in the above-mentioned background technology is to adopt the mortar pad support cushion that makes on the spot to guarantee the steel bar cover thickness, and the mortar pad production It is greatly affected by the season, and the thickness is uneven, the error is large, the strength is low, it is not easy to fix, it is easy to break and fall off

Embodiment 1

[0042] The specific control process of the present invention during slope protection, firstly through the No. 1 positioning point A, can control the position of the steel bar from the surface layer, which is the first protective layer control. Secondly, through the No. 2 positioning point B, the position of the steel bar from the soil can be controlled, which is the second protective layer control.

[0043] Through the two controls of the present invention, the following target effects can be achieved:

[0044] 1. Not only strictly and accurately control the thickness of the protective layer between the steel bar and the soil, but also strictly control the thickness of the protective layer between the steel bar and the surface layer, so as to achieve more accurate control of the thickness of the protective layer.

[0045] 2. Because the present invention fixes the position from the surface layer to the soil body, the thickness of the shotcrete can also be accurately and effect...

Embodiment 2

[0055] When the invention is used in cast-in-place concrete slabs, it can control the thickness of the protective layer of the slab and the position of steel bars. There are certain tweaks to using anchor point effects in boards. The first anchor point A is the fixed position of the gluten, and the second anchor point B is the fixed position of the bottom rib.

[0056] Embodiment 2 Introduction of each node:

[0057] No. 1 positioning point A: U-shaped card positioning point 1. The U-shaped mouth is adopted mainly because it is convenient to operate during the binding of steel bars, does not affect the binding of steel bars and does not affect the placement of vibrating rods during vibrating construction after concrete pouring. Its main purpose is to fix the gluten position and control the distance between the gluten and the surface layer.

[0058] No. 2 positioning point B: U-shaped card positioning point 2. The U-shaped mouth is adopted mainly because it is convenient to...

Abstract

The invention discloses a use method of a protection layer thickness control tool easy to operate. The use method comprises a first positioning steel bar and second positioning steel bars, a butt joint groove is formed in the inner surface of the top end of the first positioning steel bar; and the second positioning steel bars are connected to the interiors of the first positioning steel bars. According to the protection layer thickness control tool easy to operate, the top of the second positioning steel bar is inserted into the butt joint groove formed in the first positioning steel bar, then the joint of the first positioning steel bar and the second positioning steel bar is welded, finally a first clamping hoop and a second clamping hoop are clamped into a first limiting groove and a second limiting groove correspondingly, the two end feet of the first clamping hoop and the two end feet of the second clamping hoop are clamped into a first clamping groove and a second clamping groove respectively, finally, the joints between the clamping hoops and the steel bars are welded, the tool is assembled, the tool is knocked into a soil surface layer till the second clamping hoop, then concrete is sprayed to the first clamping hoop and a U-shaped top of the first positioning steel bar in a layered mode, and the purpose of controlling the concrete spraying thickness is achieved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a method for using an easy-to-operate protective layer thickness control tool. Background technique [0002] In the construction process of reinforced concrete, the thickness of the protective layer of reinforced concrete is an important indicator of the construction quality of reinforced concrete projects. The thickness of the reinforced concrete protective layer is related to the bearing capacity, durability, fire protection and other properties of the structure. Therefore, it is clearly stipulated that the thickness of the reinforced concrete protective layer should be inspected when the structural entity is inspected, and the number of sampling inspections and inspection methods are specified. Therefore, higher requirements are put forward to ensure the thickness of steel bar cover from the standard. [0003] The traditional craft is to use the mortar pads made...
