Description

Waterproof structure of steel structure roof inner gutter

technical field

The utility model relates to a building structure, in particular to a waterproof structure of an inner gutter on a steel structure roof, which belongs to the technical field of building structures.

Background technique

With the development of the economy, the proportion of the manufacturing industry is also increasing, and a large number of factories have also been born. The current factory building is usually relatively simple in structure. In order to have a large enough space, the traditional factory building structure only needs to lay roof panels on the steel frame, and the roof panels and steel frames are also fixed by welding or bolts. Although the factory building with this structure has a short manufacturing cycle, its overall tensile strength is relatively weak. Once it encounters bad weather, it is likely that the panel will fall off, or even cause the house to partially collapse. Not only that, due to the large span of large-scale factory buildings, there are often row-by-row factory buildings, so it is inevitable that assembly will occur. Between the main bodies of adjacent factory buildings, safety factors need to be considered when building foundation steel beams. It is inevitable that there will be a certain gap, and this gap will often cause water leakage. At present, when dealing with this situation, it is usually used to build a steel plate at the position of the gap to form a shield, so that the rainwater can be discharged from both sides. Although this structure can achieve a waterproof effect to a certain extent, it will If the weather and the drainage on both sides of the steel plate are not timely, there will be rainwater backflow, causing serious safety accidents.

Contents of the invention

In view of the above-mentioned deficiencies in the prior art, the main purpose of this utility model is to solve the current problems such as water leakage between factory buildings with large spans, and to provide a kind of water-proof device that can effectively deal with extreme rainy weather and has a better waterproof effect. The gutter waterproof structure inside the steel structure roof.

The technical scheme of the present utility model: the waterproof structure of the inner gutter of the steel structure roof, which is characterized in that it includes a left roof panel and a right roof panel, the left roof panel is fixed on the steel beam through the left purlin, and the right roof panel is fixed on the steel beam through the right The purlins are fixed on the steel beams; a left steel plate overhang is installed on the top of the left roof panel, a right steel plate overhang is installed on the top of the right roof panel, and on the left and right steel plate overhangs Both are provided with an inward inclined surface; a U-shaped steel plate gutter is arranged directly below the left steel plate overhang and the right steel plate overhang, and the opening of the steel plate gutter and the gap between the left roof panel and the right roof panel The gap is facing, the steel gutter is fixed on the steel beam, the inner wall of the steel gutter is provided with an anti-corrosion coating, and the opening width of the steel gutter is larger than the gap between the left roof panel and the right roof panel. Gap width. the

Optimally, a left fascia is installed on the inner end surface of the left roof panel, and a right fascia is installed on the inner end surface of the right roof panel, and the left fascia and the right fascia are both It is connected and fixed with the corresponding roof panel by rivets. The utility model can form a better protective effect on the end face of the roof panel through the left eaves panel and the right eaves panel, so that rainwater can be avoided from eroding the roof panel.

Optimally, the left purlin and the right purlin are both C-shaped steel structures. Here, the C-shaped steel structure can enhance the load-bearing capacity of the purlins and have higher strength. the

Optimally, the left roof panel and the right roof panel are both color steel roof panels. The use of color steel roof panels can reduce the weight of the roof panels, which not only reduces the load bearing of the steel beams, but also makes the installation more convenient.

Optimally, the inclination angles of the inclined planes on the left steel plate overhang and the right steel plate overhang are 40°, and the widths of the left steel plate overhang and the inclined plane on the right steel plate overhang are 15cm. By arranging the steel plate overhang, it can guide the rainwater, and at the same time, because the inclined surface of the steel plate overhang protrudes outward, it can also protect the roof panel to a certain extent.

Compared with the prior art, the utility model has the following beneficial effects:

1. Good waterproof effect: the waterproof structure of the inner gutter of the steel structure roof of the utility model can guide rainwater by lapping the steel gutter structure between adjacent roof panels and cooperating with the upper steel plate suspension on the roof panel It is discharged into the steel gutter, which has a very good waterproof effect. At the same time, because the steel gutter itself has good rigidity and can form a good isolation from the purlins on both sides, it can deal with harsh rainwater weather.

2. The overall structural strength is better: in this utility model, due to the double structure of the color steel roof panel and the ridge cover plate, the tensile resistance of the roof surface is stronger, and it can resist the invasion of relatively large rainwater and strong wind. The double structure set up to share the force can achieve the purpose of avoiding excessive local force, thus enhancing the stability of the roof.

3. The weight is lighter: the color steel roof panel adopted in the utility model has the characteristics of light weight, so that it can replace the original thick and heavy steel plate. While ensuring the strength, it also greatly reduces the weight of the entire roof top. This also reduces the stress on the bottom supporting steel frame columns.
