Description

Technical Field

[0001] The utility model belongs to the technical field of light steel roofs, in particular to a light steel roof waterproof structure. Background Art

[0002] Light steel roof refers to a roof that uses steel structure roof trusses (including portal steel frames, steel brackets, brackets, etc.) and corrugated sheet roofing, with a steel content of less than 30kg per unit area. Light steel structure is a young and vital steel structure system that has been widely used in general construction sites, agriculture, commerce, service buildings, such as office buildings, warehouses, stadiums, entertainment, tourism buildings and multi-story residential buildings.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: the waterproof structure of the existing light steel roof is usually just a conventional waterproof layer (not much different from the existing technology). When it rains, rain falls from the sky and hits the surface of the waterproof layer vertically. Over time, it will cause irreversible damage to the waterproof layer, resulting in poor waterproof effect and shortened service life.

[0004] To this end, we proposed a light steel roof waterproof structure to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a light steel roof waterproof structure. By arranging a number of equally spaced impact-reducing plates on the guide plates on both sides of the waterproof mechanism, the impact force on the waterproof layer when rainwater falls on the waterproof layer is greatly reduced, and the damage to the waterproof layer is also smaller, so that the light steel roof waterproof structure can play a better and longer-lasting waterproof role, and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A light steel roof waterproof structure, comprising an indoor cross beam frame, a guide plate constructed above the indoor cross beam frame, and a waterproof module located above the guide plate, wherein the guide plate is the main body of the light steel roof, wherein the indoor cross beam frame is in a sun shape, and is used to support the guide plate and the waterproof module thereon, wherein the waterproof module comprises a waterproof layer constructed on the upper surface of the guide plate, an upper bottom plate constructed on the upper surface of the waterproof layer, and two groups of impact reducing plates fixedly welded above the upper bottom plate, wherein the two groups of impact reducing plates are symmetrically arranged on both sides of the guide plate;

[0008] The waterproof layer may be made of asphalt waterproofing membrane, alloy waterproofing membrane or other membranes. The impact reducing plate at least includes a main body and an extension platform integrally welded to the main body, wherein both sides of the main body are formed with inclined walls. When rain falls, it hits the inclined walls at an angle, rather than directly hitting the waterproof layer or the upper bottom plate, thereby reducing the influence of rain, reducing damage to the waterproof layer, and extending the life of the waterproof layer.

[0009] A V-shaped groove is cut on both sets of impact reduction plates, and the two grooves are filled with V-shaped oblique guide plates, wherein the oblique guide plates are welded integrally with a set of impact reduction plates to guide rainwater falling on the oblique guide plates. At the same time, rainwater falling between the oblique guide plates and the highest points of the guide plates can also be affected by the oblique guide plates and will not flow downward toward the center of the guide plates, but will be guided to the edges of the guide plates, so that very little rainwater falls in the center areas on both sides of the guide plates, reducing the impact on the area, thereby achieving better waterproofing effect. Edge drain plates are fixedly welded on both sides of each oblique guide plate, and a guide pipe is welded under each edge drain plate.

[0010] As a preferred implementation scheme, support feet are welded at the four corners of the bottom wall of the indoor beam frame, and the four support feet are distributed in a rectangular array; so that the four support feet can support the indoor beam frame and the guide plate thereon, so that the guide plate and the waterproof module remain stable.

[0011] As a preferred embodiment, the extension platform extends horizontally above the main body, and the two sides of the extension platform are symmetrical to the main body; so that the impact force generated by rain falling on the extension platform is greatly reduced, reducing the impact force and vibration on the waterproof layer and the upper base plate.

[0012] As a preferred embodiment, four edge hydrophobic plates are provided and distributed in the spaces on both sides of the guide plate, and the edge hydrophobic plates are welded to the guide plate, so that the structure of the edge hydrophobic plates remains stable.

[0013] As a preferred embodiment, a U-shaped fixing sleeve is fixedly welded to the bottom of the outer wall of each guide pipe, and an extension frame is welded on the fixing sleeve, wherein the extension frame is welded to the bottom wall of the guide plate; so that the bottom of the guide pipe can be reinforced with the help of the fixing sleeve and the extension frame.

[0014] As a preferred implementation scheme, multiple groups of oblique support rods are fixedly welded on both sides of the bottom wall of the guide plate, and the multiple groups of oblique support rods are obliquely welded to the crossbeam frame inside the house; thereby the guide plate is reinforced with the help of the multiple groups of oblique support rods.

[0015] In summary, the technical effects and advantages of the utility model are as follows:

[0016] The light steel roof waterproof structure is provided with a plurality of equally spaced impact reducing plates on the guide plates on both sides of the waterproof mechanism, so that the impact force on the waterproof layer when rain falls on the waterproof layer is greatly reduced, and the damage to the waterproof layer is also less, so that the light steel roof waterproof structure plays a better and long-term waterproof role;

[0017] With the waterproof structure of the light steel roof, when it rains, part of the rainwater falling into the two oblique guide plates will flow along the two oblique guide plates to the edge drain plates on both sides thereof, and be discharged through the guide pipes on both sides. Moreover, since the oblique guide plates can intercept the rainwater falling from the highest point of the guide plates, the rainwater falling into the oblique guide plates or at a higher point will be guided to both sides of the guide plates and discharged from both sides of the guide plates, thereby reducing the amount of rainwater in the central area on both sides of the guide plates, so that people will have less rainwater when walking in this area.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-Figure 4, a waterproof structure for a light steel roof, including an indoor crossbeam frame 1, a guiding plate 4 built above the indoor crossbeam frame 1, and a waterproof module located above the guiding plate 4. On both sides of the bottom wall of the guiding plate 4, multiple groups of inclined support rods 2 are fixedly welded, and the multiple groups of inclined support rods 2 are obliquely welded to the indoor crossbeam frame 1, so as to reinforce the guiding plate 4 by means of the multiple groups of inclined support rods 2. At the four corners of the bottom wall of the indoor crossbeam frame 1, support feet 3 are welded, and the four support feet 3 are distributed in a rectangular array, so that the four support feet 3 can support the indoor crossbeam frame 1 and the guiding plate 4 thereon, etc., so that the guiding plate 4 and the waterproof module are both kept stable, wherein the guiding plate 4 is the main body of the light steel roof;

[0025] The indoor crossbeam frame 1 is in a "day" shape and is used to support the guiding plate 4 and the waterproof module thereon. The waterproof module includes a waterproof layer 5 built on the upper surface of the guiding plate 4, an upper bottom plate 6 built on the upper surface of the waterproof layer 5, and two groups of impact-reducing plates 7 fixedly welded above the upper bottom plate 6. The two groups of impact-reducing plates 7 are symmetric on both sides of the guiding plate 4. The waterproof layer 5 can be selected from roll materials such as asphalt waterproof rolls and alloy waterproof rolls. The impact-reducing plate 7 at least includes a main body 703 and an extension platform 702 integrally welded above the main body 703. Oblique walls 701 are formed on both sides of the main body 703. When rainwater falls, it slaps obliquely on the oblique walls 701 instead of directly impacting on the waterproof layer 5 or the upper bottom plate 6, which is beneficial to reducing the influence of rainwater, reducing the damage to the waterproof layer 5, and prolonging the service life of the waterproof layer 5. The extension platform 702 extends horizontally above the main body 703, and the two sides of the extension platform 702 are symmetric to the main body 703, so that the impact force generated after the rainwater falls on the extension platform 702 is greatly reduced, and the impact force and vibration generated on the waterproof layer 5 and the upper bottom plate 6 are reduced;

[0026] A V-shaped groove is cut on each of the two groups of impact reduction plates 7, and the two grooves are filled with V-shaped oblique guide plates 8, wherein the oblique guide plates 8 are integrally welded with a group of impact reduction plates 7, and the rainwater falling on the oblique guide plates 8 is guided. At the same time, the rainwater falling between the oblique guide plates 8 and the highest point of the guide plate 4 can also be affected by the oblique guide plates 8 and will not flow downward toward the center of the guide plate 4, but will be guided to the edge of the guide plate 4, so that the rainwater falling in the center of both sides of the guide plate 4 is very little, reducing the impact on this area, thereby achieving a better waterproof effect, and at each Edge drain plates 9 are fixedly welded on both sides of the oblique guide plate 8. There are four edge drain plates 9 in total and they are distributed in the space on both sides of the guide plate 4. At the same time, the edge drain plates 9 are welded to the guide plate 4, so that the structure of the edge drain plates 9 remains stable, and a guide pipe 10 is welded under each edge drain plate 9. In addition, a mouth-shaped fixing sleeve 11 is fixedly welded to the bottom of the outer wall of each guide pipe 10, and an extension frame 12 is welded on the fixing sleeve 11, wherein the extension frame 12 is welded to the bottom wall of the guide plate 4, so that the bottom of the guide pipe 10 can be reinforced with the help of the fixing sleeve 11 and the extension frame 12.

[0027] The light steel roof waterproof structure: when in use, the bottoms of the four supporting feet 3 are installed at designated positions, and the beam frame 1 in the house is kept horizontal; on rainy days, the rainwater falling into the two oblique guide plates 8 will flow along the two oblique guide plates 8 to the edge drain plates 9 on both sides thereof, and be discharged through the guide pipes 10 on both sides, and because the oblique guide plates 8 have an intercepting effect on the rainwater falling from the highest point of the guide plate 4, the rainwater falling into the oblique guide plates 8 or at a higher point than 8 will be guided to both sides of the guide plate 4 and discharged from both sides of the guide plate 4, thereby reducing the amount of rainwater in the central area on both sides of the guide plate 4, so that people will have less rainwater when walking in this area; at the same time, the rainwater will directly fall on the impact reduction plate 7, and will be greatly reduced by the action of the oblique wall 701 and the extension platform 702, so that the impact force of the rainwater is greatly reduced, so that the waterproof layer 5 and the upper base plate 6 have a longer service life, thereby playing a longer waterproof role.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
