Device for controlling floor slab steel bar spacing and slab thickness

Abstract

The invention discloses a device for controlling floor slab steel bar spacing and slab thickness. The device comprises a fixing sleeve, an anchoring steel sheet, a pushing rod and a plurality of rectangular concrete blocks, wherein the adjacent rectangular concrete blocks are arranged on a floor slab base surface at intervals of two meters; the arrangement direction of the rectangular concrete blocks is consistent with the arrangement direction of steel bars on the floor slab base surface; arc-shaped notches for placing the steel bars are formed in the same sides of the top surfaces and the bottom surfaces of the rectangular concrete blocks respectively; connecting holes for the fixing sleeve to penetrate through are formed in the rectangular concrete blocks and located in the other sides of the arc-shaped notches in the vertical direction; and the detachable anchoring steel sheet is arranged at the top end, penetrating through the connecting holes of the rectangular concrete blocks, of the fixing sleeve. The strength grade of the rectangular concrete blocks is the same as that of floor slab concrete of a used floor, the height of the rectangular concrete blocks is consistent with the thickness of the floor slab of the used floor, and the effect of controlling the floor slab thickness and the steel bar spacing can be achieved.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a device for controlling the distance between reinforcement bars and the thickness of a floor slab. Background technique [0002] At present, the traditional concrete slab thickness control methods include: (1) when pouring concrete, insert steel bars into the concrete for measurement; (2) mark the slab thickness 1m or 500mm control line on the reserved vertical steel bars of the wall column, and pour When concrete, use a ruler to measure, etc. Although this method can control the thickness of the concrete floor, it will be greatly affected by the level of workers and the environment, and it is easy to produce large errors, which will increase the risk of processing the floor thickness or strengthening measures in the later stage. [0003] The methods to control the spacing of steel bars are: use cement horse stool. When the staff walks on the operating surface, t...

AI Technical Summary

Problems solved by technology

When the staff walks on the operation surface, the concrete horse stool is easy to fall, and the steel bars are easy to shift, which leads to the reduction of the spacing of the steel bars and the large protective layer of the steel bars, especially the steel bars of the cantilevered slabs are prone to this phenomenon
