Description

Technical Field

[0001] The utility model relates to the technical field of steel building structures, and particularly relates to a light steel keel structure sloping flat roof. Background Technique

[0002] Due to the small slope of the flat roof, material slope finding is usually adopted. That is, the designed slope is achieved by changing the thickness of materials (generally a cement mortar slope finding layer) at different positions on the roof. However, the production of the cement mortar slope finding layer belongs to wet operation, which is not conducive to accelerating the construction speed. For the profiled steel sheet or sandwich panel roof system without wet operation, the structural slope finding method is usually adopted, and the structural design is more complicated and generally used for pitched roofs.

[0003] At present, aiming at the characteristics of dry construction, flat roof and small slope of small buildings, there is still a lack of a solution with simple structure, low cost, reliable performance and controllable quality. Content of the Utility Model

[0004] The purpose of the utility model is to provide a light steel keel structure sloping flat roof to solve the above problems. Through simple cutting, nailing or connecting with structural adhesive of the light steel keel, slope finding can be realized by means of the structure, with simple structure, low cost, reliable performance and controllable quality.

[0005] Technical solution: The utility model provides a light steel keel structure sloping flat roof, including: slope finding ribs, end connectors, structural surface layer, insulation board. The slope finding ribs are formed by obliquely cutting a U-shaped light steel keel along the diagonal and then reversing and splicing it into a Z-shaped structure. The webs overlap and are fixed by self-tapping and self-drilling screws. A number of slope finding ribs are provided. The upper inclined surface is the slope surface layer, and the lower plane is the connection layer; the end connectors are arranged at one end of the Z-shaped structure of the slope finding ribs; the structural surface layer is arranged outside the slope finding ribs and the end connectors; the insulation board is laid above the structural surface layer on the slope surface layer. The slope finding ribs are formed by cutting and splicing a U-shaped light steel keel. The two transverse plate parts thereof are stacked to improve the bearing capacity of the slope surface. The structure is simple, the cost is low, the difficulty of slope finding construction is reduced, and quality control is easy.

[0006] Further, for the above-mentioned light steel keel structure sloping flat roof, the right-angle side of the lower connection layer of the slope finding ribs is connected with the building components below through self-tapping and self-drilling screws, and the upper slope surface layer is fixedly connected with the structural surface layer through self-tapping and self-drilling screws, and the edge of the structural surface layer is adhered with structural adhesive. The construction difficulty is reduced and the cost is low.

[0007] Further, for the above-mentioned light steel keel structure sloping flat roof, the slope finding ribs and the end connectors both adopt U-shaped light steel keels of the same specification. Using U-shaped light steel keels of the same specification, whose sizes correspond to those of the slope finding ribs, is convenient for operators to construct and reduces the cost.

[0008] Furthermore, for the above-mentioned lightweight steel keel structure sloping flat roof, the structural surface layer and the insulation board material can adopt heat-insulating tile lining boards to integrate the structural surface layer and the insulation board, using only one type of board.

[0009] Furthermore, for the above-mentioned lightweight steel keel structure sloping flat roof, the structural surface layer adopts oriented strand board (OSB).

[0010] Furthermore, for the above-mentioned lightweight steel keel structure sloping flat roof, the insulation board adopts a polyurethane insulation layer.

[0011] Furthermore, for the above-mentioned lightweight steel keel structure sloping flat roof, the structural surface layer and the insulation board are set with their edges aligned, and the structural surface layer and the insulation board of the sloping surface layer are pressed against the structural surface layer and the insulation board set on the side. This can improve the sealing performance of the roof and prevent water seepage from the edge part.

[0012] From the above technical solutions, it can be seen that the present utility model has the following beneficial effects: For the lightweight steel keel structure sloping flat roof described in the present utility model, the sloping of the flat roof is achieved through the structural sloping ribs, with a simple structure and low cost; by using U-shaped lightweight steel keels, cutting them and laying the boards, the difficulty of the sloping construction is reduced, and it is easy to control the quality. In addition, the U-shaped lightweight steel keel itself serves as a connecting member between the sloping layer and the structural surface layer, making the connection with the lower building very convenient.
