Light steel pitched roof substrate dry tile hanging structure and method for changing plane roof into pitched roof

Abstract

The invention discloses a light steel pitched roof substrate dry tile hanging structure and a method for changing a plane roof into a pitched roof. The structure comprises a light steel pitched roof substrate and a plurality of stand columns. A board (6), a waterproof coil material (7) and counter battens (8) arranged on the light steel pitched roof substrate. A vertical column of cover tiles (10) are arranged on each counter batten (8). Each cover tile (10) is nailed to the board (6). The method is characterized in that each cover tile (10) is nailed to the board (6) through a self-tapping screw penetrating through a second preformed hole and the corresponding counter batten (8); an upper arc protruding strip (10.1) of each cover tile (10) is inserted into a clamping groove (12) of the last cover tile (10) in the same column; and the second preformed hole of an upper arc plate (10.2) of each cover tile (10) is covered by an arc main body (10.3) of the last cover tile (10) in the same column. According to the structure and method, the shock resistance is good, the construction period is short, and mounting is convenient.

Description

technical field [0001] The invention relates to building reconstruction and decoration construction technology in the field of civil engineering, in particular to a light steel sloping roof base dry hanging tile structure and a method for changing a flat roof to 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 bigges...

Problems solved by technology

[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. As a result, the base layer of the original structure (even the foundation of the original house) may need to be reinforced and reinforced before the sloping roof can be reconstructed. This will not only reduce the construction cost The large increase and the extension of the construction period are not conducive to the development of green construction and environmental protection
