Cornice plug-in gutter structure and installation method

Abstract

The invention provides a cornice plug-in gutter structure and an installation method. Indoor water leakage can be effectively prevented, structure combination is convenient, and installation is convenient. The gutter structure is characterized in that a purline hanger is fixedly installed on a body steel frame, a cornice purline is located on the inner side of a wall surface and fixed to the purline hanger, an insulation layer is fixed to the upper end of the cornice purline through a screw, cornice bent angle steel is in an elongated slot type, the elongated slot type cross section is provided with a left side wall, a right side wall and a top plane, the right side wall is located on the inner side of the wall face and fixed to the cornice purline, the left side wall is located on the outer side of the wall face, the top plane is a preset distance higher than the upper end of the purline, a trough of a roof panel is supported on the top plane, and a screw is located below the trough and separated from the trough; on the outer side of the wall face, the trough of the roof panel is fixed to the top plane of the cornice bent angle steel through a bolt, and the plug-in gutter is installed on the left side wall of the cornice bent angle steel through a supporting assembly.

Description

technical field [0001] The invention relates to the field of building steel structures, in particular to an external gutter structure and an installation method of a cornice. Background technique [0002] At present, many factories adopt the form of steel structure. The characteristics of steel structure factory buildings are as follows: 1. Steel structure buildings are light in weight, high in strength and large in span; 2. The construction period of steel structure buildings is short, which reduces investment costs accordingly; 3. Fire resistance of steel structure buildings High, strong corrosion resistance; 4. The steel structure building is easy to move, and the recycling is pollution-free. [0003] figure 1 It is a schematic diagram of a steel structure factory building, such as figure 1 As shown, the top of the factory building is a metal roof panel 101 extending obliquely to the left and right sides with a certain slope, the left and right sides are gables 103, the...

Problems solved by technology

[0005] In this structure of the prior art, because of its inherent construction procedures, the screws 34 penetrate the roof panel. Although certain waterproof measures are adopted, gaps are very likely to be formed at the penetration after thermal expansion and contraction or long-term wind and sun exposure. And the screw 34 is located inside the wall, which causes the leaked rainwater to enter the inside of the factory building, causing losses to the production inside the factory building.
