Light steel slope roof foundation layer dry tile hanging structure and construction method of changing plane roof into slope roof

Abstract

The invention discloses a light steel slope roof foundation layer dry tile hanging structure and a construction method of changing a plane roof into a slope roof. The structure comprises a light steel slope roof foundation layer and multiple uprights, a plank (6), a waterproof roll (7) and counter battens (8) are arranged on the light steel slope roof foundation layer, a vertical column of tiling pieces (10) are arranged on each counter batten (8), and each tiling piece (10) is nailed on the plank (6). The structure is characterized in that each tiling piece (10) is nailed on the plank (6) through a self-tapping screw penetrating a second reserved hole and the corresponding counter batten (8), and the lower end of each tiling piece (10) covers an upper arc-shaped piece (10.2) of a next tiling piece (10) in a same column to enable all arc-shaped bodies (10.1) of the tiling pieces (10) in the same column to be positioned on a same arc surface. The structure and the method are high in anti-seismic performance, short in construction period and convenient in mounting.

Description

technical field [0001] The invention relates to building transformation and decoration construction technology in the field of civil engineering, in particular to a construction method for a light steel sloping roof base dry-hanging tile structure and a flat roof for a sloping roof. Background technique [0002] In the process of new urbanization construction, ecological garden city and old city reconstruction in our country, it is often necessary to transform the flat roof of the building into a sloping roof. [0003] The conventional method is to add a layer of reinforced concrete structure to the slope roof on the basis of the original flat roof. The construction of the surface layer tiles usually adopts two methods: dry laying and wet laying: the dry laying method refers to that the concrete has reached the design strength. Fix the horizontal tile hanging strips on the sloping roof, and hook the tiles on the corresponding hanging tile strips from bottom to top, but the b...

[0003] The conventional method is to add a layer of reinforced concrete structure to the slope roof on the basis of the original flat roof. The construction of the surface tile usually adopts two methods: dry laying and wet laying: the dry laying method means that the concrete has reached the design strength. Fix horizontal tile hanging strips on the sloping roof, and hook the tiles on the corresponding hanging tile strips from bottom to top, but the biggest drawback of this construction method is that each tile is hooked on the hanging tiles. If it is on the strip and is pressed by the tiles above, the connection method of the tiles is not reliable, and its anti-seismic performance is poor, and the tiles are easy to fall when encountering vibrations, strong winds, etc.

The other is the wet laying method, which is to spread a layer of cement mortar on the concrete sloping roof, and then bond the tiles piece by piece. Compared with the dry laying method, this construction method improves the seismic performance of the tiles, but The construction process is cumbersome and the load on the original roof structure is also greatly increased, so it may be necessary to reinforce and reinforce the base of the original structure (even the foundation of the original house) before the slope roof can be reconstructed, which not only increases the It increases the construction cost and prolongs the construction period, which is not conducive to the development of green construction and environmental protection.
