Description
Technical Field
The utility model relates to a novel fiber inserting tool for measuring the thickness of concrete in the concrete pouring process.
Background
At present, when a concrete floor slab is poured in the construction industry, the thickness of the poured concrete is generally measured by the following three ways to ensure that the thickness of the floor slab meets the design requirements:
(1) a fiber inserting tool is manufactured, and a transverse steel bar is welded on a vertical steel bar according to the pouring height of the concrete floor slab;
(2) the stay wire is pulled on the wall column steel bar, and the thickness of the stay wire and the height of the concrete pouring finished surface are controlled;
(3) and (4) pre-burying the water stopping joints, wherein the thickness of the water stopping joints which are as high as the concrete to be poured are pre-buried on the surface of the template for thickness control.

(1) the fiber insertion tool is generally manufactured by a concrete team, and a transverse short steel bar is welded on a vertical steel bar according to the thickness of a cast-in-place concrete floor slab. One deck face often has a plurality of thicknesses in actually pouring, and self-control instrument is not practical because highly fixed this moment, need be according to the actual thickness preparation a plurality of instruments of floor when. And because the thickness of the floor slab is about 100mm generally, workers need to bend over to judge whether the lower surface of the transverse positioning steel bar is attached to the cast-in-place plate surface, and the error range of the thickness of the floor slab is only-5 mm to +10 mm. Because the workman need bend over the body and judge, and floor thickness error value requires very little, very big increase the risk that thickness is not up to standard.
(2) The stay wires are used for tensioning thin wires at the same height on wall column reinforcing steel bars on two sides or diagonal positions of a floor slab poured in a current layer, and the thickness of the floor slab is judged by the distance between the height of the stay wires and a concrete surface when the floor slab is poured. When concrete is poured, the reinforcing steel bars for fixing the thin lines are in a shaking state due to impact load when the concrete is poured, vibration of the vibrating bars and the influence of artificial factors. Therefore, the height of the line and the finished plate of the cast-in-place floor slab is difficult to keep fixed, and a large error exists.
(3) The embedded water stop joints are required to be arranged at four corners of each plate and on the spanned templates, and when the pouring area is large or the thickness of the floor slab changes greatly, one floor slab needs to be timely or even hundreds of water stop joints. Therefore, a large cost is required.
