Support frame for guaranteeing thickness of protective layer of floor slab and construction method thereof

Abstract

The invention relates to a support frame for guaranteeing the thickness of a protective layer of a floor slab and a construction method thereof. The support frame comprises a bracket welded by a plurality of galvanized steel tubes on a plane as well as a plurality of supporting feet being vertical to the plane of the bracket; wherein, the supporting feet are supported on a floor slab template arranged at the bottom of the floor slab, and the lengths of the supporting feet can ensure the plane of the bracket to be higher than that of a surface reinforcing rib of the floor slab. The invention adopts the bracket with a structure of 'B'-shape of 'MU'-shape like a Chinese character in a creative way, so that the processing and construction are convenient. As the lengths of the supporting feet can ensure the plane of the bracket to be higher than that of the surface reinforcing rib of the floor slab, the surface reinforcing rib of the protective layer of the floor slab can be effectively protected, and the thickness of the protective layer of the floor slab is guaranteed. The invention also creatively provides the construction method for manufacturing and installing the support frame, thus well controlling and improving the construction quality.

Description

technical field [0001] The invention relates to a shaped support for ensuring the thickness of the protective layer of the concrete floor, in particular to a support frame which can effectively ensure that the thickness of the protective layer of the floor is still maintained after the concrete is poured. The present invention also relates to the construction method of the above support frame. Background technique [0002] At present, general buildings all adopt reinforced concrete floor slabs, and the structure of its protective layer is to set up upper reinforcing bars (gluten bars) and lower reinforcing bars (bottom bars) configured vertically and horizontally above the floor formwork. In order to protect these gluten and bottom bars from being damaged, the patent No. 200720127870.0 discloses a concrete floor steel bar supporter, the supporter is arranged in the reinforced concrete floor, and its upper support area is supported by the upper reinforcement in the floor.

AI Technical Summary

Problems solved by technology

The inventors found that although the above technology can better protect the bottom rib of the floor protection layer, it has the following disadvantages: 1. The structure is more complicated, and the processing and installation are time-consuming and laborious; 2. Since the supporter is located under the gluten, Therefore, when the staff binds the steel bars and pours the concrete, it is difficult to avoid the bending of the floor gluten caused by human stepping, so the gluten of the floor protective layer is difficult to be protected
