Description

A eaves hanging gutter structure

technical field

The utility model relates to the field of building steel structures, in particular to a gutter structure with external cornices.

Background technique

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.

Figure 1 is a schematic diagram of a steel structure factory building. As shown in Figure 1, the top of the factory building is a metal roof panel 101 with a certain slope extending to the left and right sides, the left and right sides are gables 103, and the front is a cornice 102. There is a main body inside the factory building Supporting structures such as steel frames. Wherein, the metal roof panel 101 is not flat. As shown in FIG. 2 , the roof panel has periodic crests 211 and troughs 212 .

In order to prevent rainwater from overflowing, external gutters shall be set under the metal roof of the eaves to collect and divert rainwater. Fig. 3 is the structural diagram of the gutter outside the eaves of the prior art. As shown in Fig. 3, the roof panel has crests 311 and troughs 312, and eaves angle steel 33 is fixed on the main steel frame 32, and glass wool 35 is fixed on the eaves by screws 34 On the angle steel 33 , and the screw 34 penetrates the trough 312 of the roof panel, and the external gutter 36 is arranged on the outside of the wall 37 .
