Description

Technical Field

[0001] The utility model relates to the technical field of building structure design, and specifically relates to a steel structure for the roof of a prefabricated panel house building. Background Technique

[0002] For a structural roof, a steel structure is mainly used to build a frame structure on the roof of a house, and then tiles are laid on the frame structure to form a steel structure roof. At present, the common steel structure roof is a double-slope structure. A triangular frame structure is built by the steel structure, and then the color steel tiles are fixed on the frame by screws, so that the color steel tiles and the steel structure frame cooperate with each other to form a steel structure roof.

[0003] A steel structure roof with the application number CN202310065246.6 is specifically disclosed, including a frame arranged on the roof, a tile body, and a connecting piece connecting the frame and the tile body. The tile body includes symmetrically arranged rain shielding parts and connecting parts. The rain shielding parts and the connecting parts are respectively arc-shaped convex structures. The connecting part is located between the two rain shielding parts and the radius of the connecting part is greater than the radius of the rain shielding part. The rain shielding parts of adjacent tile bodies are clamped and connected to each other; the connecting piece includes an installation sleeve sliding on the frame and abutting plates symmetrically hinged to the installation sleeve. The inner wall of the connecting part is symmetrically inclined with connecting plates. The installation sleeve is provided with a control component for controlling the abutting plate to flip to abut against the connecting plate. When the tile body moves away from the frame after the abutting plate flips, the connecting plate abuts against the abutting plate; the abutting plate is symmetrically slid with clamping plates, and the abutting plate is provided with a driving component. When the abutting plate abuts against the connecting plate, the driving component drives the two clamping plates to clamp the connecting plate. Since the steel structure of the roof of the existing prefabricated panel house building is prone to snow accumulation on the top of the roof and the snow is inconvenient to remove in snowy weather, we hereby propose a steel structure for the roof of a prefabricated panel house building.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following is a description of the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model and are not intended to limit the present utility model.

[0024] Embodiment: As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , a steel structure for the roof of a prefabricated panel house according to the utility model includes a frame 1. The frame 1 is triangular in shape. Scraping strips 2 are arranged on both sides of the frame 1. The scraping strips 2 are arranged in a triangular prism shape, and both sides of the scraping strips 2 are inclined planes. Slide grooves 3 are opened on the inclined edges of the front and rear sides of the frame 1. Sliders 4 are slidably arranged in the slide grooves 3. Guide rods 5 are arranged in the slide grooves 3. The guide rods 5 penetrate through the sliders 4 and are fixedly connected to the frame 1 at the ends. One end of the slider 4 extends outside the slide groove 3. Connecting blocks 6 are fixedly connected to both ends of the scraping strip 2, and the ends of the connecting blocks 6 are fixedly connected to the sliders 4. Two first rotating shafts 7 arranged at intervals are rotatably installed on the upper part of the frame 1. First pulleys 8 are fixedly installed on the first rotating shafts 7. First rope bodies 9 are fixedly connected to the sliders 4. The first rope bodies 9 are wound around the first pulleys 8 on the same side as them. The lower ends of the first rope bodies 9 are fixed to external heavy blocks, for example, tied to stones on the ground.

[0025] The inclined plane design of the triangular roof helps to disperse the impact of wind on the roof, can reduce the concentrated action of wind on the roof, improve the wind resistance of the roof. At the same time, snow is likely to slide off due to gravity on the top of the frame 1, thus reducing snow accumulation. Then, by setting the scraping strips 2 to clean the snow, by releasing the lower end of the first rope body 9, the scraping strips 2 slide along the inclined plane of the frame 1 and clean the snow, which is convenient for residents to clean the snow.

[0026] Among them, second rotating shafts 10 can be rotatably installed at both ends of the frame 1. Second pulleys 11 are fixedly installed on the second rotating shafts 10. Second rope bodies 12 are fixedly connected to the sliders 4. The second rope bodies 12 are wound around the second pulleys 11 on the same side as them. The two sides of the top of the frame 1 are set as smooth surfaces, which can reduce the friction force on the top of the frame 1 and make snow not easy to accumulate on the roof. When the snow freezes below and adheres to the frame 1, only sliding the scraping strip 2 itself cannot achieve effective cleaning. Therefore, by pulling down the lower end of the second rope body 12 and the lower end of the first rope body 9 is in a free state, by pulling the scraping strip 2 to slide from top to bottom along the slide groove 3, the pushing force of the scraping strip 2 can be increased, so as to remove stubborn snow. The scraping strip 2 is arranged in a triangular prism shape, and the scraping strip 2 is easier to cut into the snow, which can improve the snow cleaning efficiency. After the cleaning is completed, then by pulling the lower end of the first rope body 9, the scraping strip 2 slides from bottom to top and returns to a high position to cope with the next snow cleaning work.

[0027] Among them, a column 13 is fixedly installed at the center inside the frame 1. Reinforcing plates 14 are fixedly installed on both sides of the column 13. The reinforcing plates 14 are fixedly connected to the lower end of the column 13. The two reinforcing plates 14 and the column 13 divide the internal space of the frame 1 into multiple triangular spaces. By setting the reinforcing plates 14 and the column 13, the support strength of the frame 1 is improved.

[0028] Among them, a cavity 15 is provided at the lower end of the frame 1, and a plurality of equidistantly distributed support columns 16 are fixedly installed in the cavity 15. The cavity 15 is filled with thermal insulation foam 17. The strength of the cavity 15 is improved by the support columns 16, so that the cavity 15 is not easy to collapse. By filling the cavity 15 with thermal insulation foam 17, the thermal insulation efficiency of the roof can be improved.

[0029] Among them, a bottom plate 18 is fixedly installed at the bottom of the frame 1, and the center of gravity of the roof structure is lowered by the bottom plate 18, so as to improve the stability of the roof. Limiting parts 19 are fixedly installed at both ends of the bottom of the bottom plate 18. Both sides of the limiting part 19 are set as upward inclined surfaces. The limiting part 19 is buried in the top of the house. The special shape of the limiting part 19 makes it difficult for the limiting part 19 to separate from the top of the house, so that the limiting part 19 can improve the connection strength between the roof and the main body of the house.

[0030] Working principle: The scraper bar 2 is set to clear the snow. By releasing the lower end of the first rope body 9, the scraper bar 2 slides along the inclined surface of the frame 1 and clears the snow, which is convenient for residents to clear the snow. When the snow is frozen and adsorbed on the frame 1, by pulling down the lower end of the second rope body 12, and the lower end of the first rope body 9 is in a free state, by pulling the scraper bar 2 to slide from top to bottom along the slide groove 3, the driving force of the scraper bar 2 can be increased, so as to clear the stubborn snow. After the clearing is completed, the scraper bar 2 slides from bottom to top and returns to a high place by pulling the lower end of the first rope body 9 to cope with the next snow clearing work.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
