Description

Technical Field

[0001] The utility model relates to the technical field of light steel roof waterproofing, and more specifically, particularly relates to a waterproof structure and a light steel roof thereof. Background Art

[0002] Light steel roof is a roof structure that uses steel structure (including doors or steel frames, steel trusses, brackets, etc.) and corrugated sheet roofing. Its unit area is less than 30kg and its weight is light. Therefore, light steel roof is increasingly used in modern times. However, in order to reduce costs, rural areas only use color steel plates to make roof structures. Color steel plates are fixed to the frame with screws. After long-term use, the corrosion and damage of the screws are relatively more serious and are prone to water seepage and leakage. Utility Model Content

[0003] The utility model aims to overcome the problem of easy corrosion and leakage at the existing light steel roof screw connection and to provide a waterproof structure for the light steel roof screw connection and a light steel roof using the waterproof structure.

[0008] Furthermore, a guide plate is provided at the bottom of the waterproof cover. The length of the guide plate is the same as that of the waterproof cover and the lower end is fixedly connected to the waterproof cover. A guide groove is formed between the top surface of the guide plate and the waterproof cover.

[0009] Furthermore, the waterproof cover is in an inverted trapezoidal structure or an arc-shaped structure.

[0010] A light steel roof including the above-mentioned waterproof structure also includes a light steel frame and a light steel roof panel installed on the light steel frame, the upper layer of the light steel roof panel is a color steel plate, and the color steel plate is provided with a plurality of upwardly protruding ridges at equal intervals along the longitudinal direction, one or more of the ridges are connected to the light steel frame by bolts, and the waterproof structure is arranged on the ridges where the bolts are arranged.

[0011] Furthermore, the two light steel roof panels are combined to form an inverted V-shaped structure, and a waterproof top plate is arranged above the junction of the two light steel roof panels. The waterproof top plate has a structure that is narrow at the top and thick at the bottom, and the orthographic projection of the waterproof top plate at least covers the top surfaces of the two ridges closest to the junction of the two light steel roof panels.

[0012] Furthermore, the waterproof top plate has an arc-shaped, V-shaped or trapezoidal structure, and the lower end of the waterproof top plate extends to the upper surface of the color steel plate.

[0013] Furthermore, the lower layer of the light steel roof panel is an insulation layer, and the insulation layer is fixed to the bottom surface of the color steel plate.

[0015] The waterproof structure in the utility model is arranged on the light steel roof panel, and bolts are arranged on the ridge of the color steel plate of the light steel roof panel. The light steel roof panel is connected to the light steel frame through the bolts. By arranging a waterproof cover on the ridge with the bolts and covering the bolts with the waterproof cover, it is effectively avoided that the bolts are contacted with rainwater to cause corrosion, and it is also avoided that rainwater enters the gap at the bolt connection to cause water seepage and leakage.

[0016] The waterproof cover has a narrow upper and thick lower structure, which allows rainwater to flow down along the two sides of the waterproof cover. By setting a connecting plate, the connecting plate is connected to the color steel plate, which is convenient for installing the waterproof cover on the one hand, and the upper end of the connecting plate is fixedly connected to the waterproof cover on the other hand, and the lower end of the connecting plate extends to the upper surface of the color steel plate and is located on both sides of the ridge, so that the ridge can be completely covered to enhance the waterproof effect. By setting a guide plate, a guide groove is formed between the guide plate and the waterproof cover, and rainwater on the waterproof cover flows into the guide groove along the two sides of the waterproof cover and flows out through the notches at both ends of the guide groove, preventing rainwater from continuing to scour the color steel plate.
