Description

A split and assembled prefabricated cabin and its centralized drainage structure on the roof

technical field

The invention relates to a detachable and assembled prefabricated cabin and its roof centralized drainage structure.

Background technique

At present, the country has made a major decision to build a resource-saving and environment-friendly society, and strives to speed up the transformation of the economic development mode, making every effort to break through the resource and environment bottlenecks in development. This change has also had a profound impact on the development of the power industry. The construction mode of substations must move towards reducing land occupation, reducing construction costs, shortening the construction period, and achieving a development mode that is more coordinated with the surrounding environment and operates more reliably. The adoption of the prefabricated cabin design mode promotes the modularization of substation construction and shortens the on-site construction and test cycle.

For example, Chinese patent CN204804198U (authorized announcement date 2015.11.25) discloses a prefabricated cabin breathable and waterproof structure, including a cabin body and a top cover arranged on the top of the cabin body. The cabin body includes a cabin body frame, a sealing plate and a door panel. The top frame is made of square steel. The top cover includes a herringbone roof frame and a top plate, the top plate is welded on the top of the skeleton formed by the herringbone top cover, the top plate is spliced by several top plate panels, and the top surface of the top plate has a concave-convex structure. A breathable waterproof part is also arranged between the cabin body and the top cover. However, this type of waterproof structure still adopts decentralized drainage. With more and more prefabricated cabins currently being used in power grid projects, it has become a trend to replace the scattered drainage with the structure of prefabricated cabin rainwater centralized drainage. Compared with the split and assembled prefabricated cabin structure, the integrated welded prefabricated cabin is not easy to achieve centralized drainage on the roof.

Detailed ways

The embodiment of the disassembled and assembled prefabricated cabin of the present invention: as shown in Figure 1-16: including cabin body 1, cabin roof, cabin body roof is provided with roof centralized drainage structure, and roof centralized drainage structure includes the length direction along the front and rear direction The extended skeleton 7 has a triangular cross section. The left and right sides of the framework 7 are provided with drainage grooves extending along the front and rear directions for collecting rainwater on the top of the prefabricated cabin. A hanging plate 8 is arranged between the drainage groove and the framework 7, and the hanging plate 8 is fixed on the framework 7. Drain groove is fixed on the hanging plate 8.

The drainage groove is segmented, including multi-section drainage groove bodies 2, and a backing plate 11 for preventing water leakage is arranged at the joint of two adjacent drainage groove bodies 2. The drainage tank body 2 is U-shaped with the opening facing upwards. The upper ends of the left and right side plates of the drainage tank body 2 are bent inward, and a row of installation holes are arranged at intervals along the length direction of the drainage tank body on the folded edges. . The backing plate 11 is also U-shaped, and is fixed to the drainage tanks on both sides by welding. The multi-section drainage groove body is connected by the backing plate 11 to form a drainage groove whose length is consistent with the length of the cabin body. At intervals of one or two drainage tanks, a drain hole 21 is provided on the drainage tank to communicate with the drain pipe 6, and the water in the drain tank is discharged through the drain pipe 6 in a concentrated manner.

A water retaining plate 4 is correspondingly provided on the side away from the framework of each drainage tank body, and the water retaining plate 4 is inclined toward the side of the framework. The quantity of the water retaining plate 4 is consistent with the quantity of the drainage tank body. The water retaining plate 4 is formed by two parts of inclined plates, that is, the upper inclined plate 41 and the lower inclined plate 42. The inclination between the upper inclined plate 41 and the roof plate arranged on the skeleton The angles are the same, the angle of inclination of the lower inclined plate 42 is greater than that of the upper inclined plate, and the lower end of the lower inclined plate 42 is provided with a mounting hole for being fixedly installed on the drainage tank body. The water retaining plate 4 is fixed on the roof panel 5 by the water retaining plate support 9, and the water retaining plate support 9 is fixed to the water retaining plate 4 upper end by the rivet, and the water retaining plate support 9 is fixed on the roof plate by the rivet. The section of the water retaining plate bracket 9 is Z-shaped. The upper inclined plate 41 is located above the roof panel 5 to form a water inlet space. The top surface of the roof panel 5 is arranged in a concave-convex structure, which is a concave-convex groove 51 at intervals between the concave and convex, and the roof panel 5 is fixed on the skeleton 7 by a long drill tail. The outside of the roof panel 5 is a sheet metal structure, and the middle interlayer is plastic. When in use, rainwater and melted snow water flow out along the concave-convex groove of the roof panel, and the water is introduced into the drainage groove through the water retaining plate.

Further, a square hole 43 and a cover plate 3 for blocking the square hole 43 are also provided on the water retaining plate, and the cover plate 3 is fixed on the drainage groove by self-tapping screws. The cover plate 3 can be taken off when cleaning the drain, and can be installed after cleaning.

The hanging plate 8 includes a hanging plate 81 for hanging on the frame, and a fixed connecting plate 82 extending along the vertical direction for fixed connection with the water supply and drainage grooves. The angle of inclination of the hanging gusset 81 is consistent with that of the skeleton. After the hanging gusset 81 is hung and buckled, the roof panel 5 is press-fitted on the hanging gusset 81. The lower end of the fixed connecting plate 82 is folded inwardly to form a U-shaped flange 83, and the bottom of the U-shaped flange is provided with through holes 84 for drainage and ventilation, and there are a plurality of through holes 84 in one group. The outer surface of the fixed connecting plate 82 forms a welding fixing surface for welding and fixing the drainage groove. In the present embodiment, setting the hanging plate is to consider the following factors; if the drainage channel is directly welded and fixed on the rectangular steel pipe 10 on the periphery of the skeleton, the fixation is not firm, especially in heavy rain and rainstorm weather, the weight of the drainage channel is relatively large; The prefabricated cabin is disassembled and assembled. The space between the cabin and the roof panel is breathable and not closed. When the water in the drainage tank overflows, the water may enter the cabin. After installing the hanging board, The overflowing water just can be discharged through the through hole on the hanging plate. When it is not raining, the through holes on the hanging board can play a role of ventilation.

In other embodiments, the drainage groove can also be an integral U-shaped groove, and the drainage groove is not limited to U-shaped, and can also be V-shaped. The water retaining plate on the gutter can also adopt a flat plate inclined towards the roof panel side. In addition, the water retaining board can also be directly fixed on the roof panel without using the water retaining board bracket.

In other embodiments, the hanging plate may only be used to fix the drainage groove without providing corresponding through holes, and naturally no U-shaped flanges are provided.

In the embodiment of the concentrated drainage structure on the roof of the prefabricated cabin of the present invention, the concentrated drainage structure on the roof is the same as the centralized drainage structure on the roof in the above-mentioned embodiment of the prefabricated cabin, and the specific structure will not be described in detail.
