Description

Technical Field

[0001] The utility model relates to the technical field of energy-saving self-insulating integrated factory building roofs. Background Art

[0002] The roof structure of the steel structure factory is currently built by combining purlins and corrugated thin steel plates. This type of roof structure has the characteristics of simple structure and easy installation, so it is widely used. However, the corrugated thin steel plate roof structure also has disadvantages, especially in geographical environments such as the hot south or the cold north. The indoor temperature of the workshop in winter is too high or too low, which is not good for the health of production workers. In order to save energy, an energy-saving self-insulating roof structure is needed to reduce the problem of high energy consumption of the factory building caused by unreasonable roof structure.

[0003] The thermal insulation capacity of a roof can be simply measured by its thermal resistance. The greater the thermal resistance, the less heat passes through, and the better its thermal insulation performance. This technology improves the thermal insulation and heat preservation effect of the roof system by redesigning the roof system and designing an energy-saving self-insulating integrated roof system.

[0006] The energy-saving self-insulating integrated factory building roof structure has purlins arranged on the inclined beams of the steel structure, and the energy-saving self-insulating integrated roof panels are fixed on the purlins. The characteristic is that the energy-saving self-insulating integrated roof panels include corrugated steel plates, foamed insulation layers and high-strength concrete layers from top to bottom, and the high-strength concrete layer includes a lower flat plate portion and an upward convex rib portion, a steel truss is arranged in the rib portion, and a steel mesh is arranged in the flat plate portion.

[0007] Furthermore, the steel truss is a triangular steel truss.

[0008] Furthermore, a connecting angle code is arranged on the back of the energy-saving self-insulating integrated roof panel, and the connecting angle code is provided with bolt holes and is fixed to the purlin by fasteners.

[0009] Furthermore, the connecting angle code is fixed to the steel wire mesh by welding.

[0010] Furthermore, the energy-saving self-insulating integrated roof panel and the purlin are welded or fastened by a bolt assembly.

[0011] Furthermore, the purlin is a C-shaped or Z-shaped cold-rolled thin-walled steel purlin.

[0012] Furthermore, the upper surface of the corrugated steel sheet is provided with a color coating.

[0013] Furthermore, the overlapping parts on both sides of the energy-saving self-insulating integrated roof panel are connected by tongue and groove fitting.

[0014] Furthermore, the thickness of the foam insulation layer is 5 cm.

[0015] Furthermore, the foamed thermal insulation layer is designed to have a constant thickness.

[0016] The beneficial effects of the utility model are:

[0017] The roof structure of this factory uses energy-saving self-insulating integrated roof panels as panels, which are equipped with foam insulation layers and installed on the roof of the factory to improve the indoor thermal environment of the factory and reduce energy consumption. The installation process is quickly installed by tightening bolts, and has the characteristics of high installation speed.

[0031] The factors that need to be considered for the energy-saving self-insulating integrated factory roof structure include but are not limited to: insulation, heat preservation, waterproofing, and ease of installation.

[0032] refer to Figures 6 to 8 The steel structure workshop surface structure is provided with C-shaped or Z-shaped cold-rolled thin-walled steel purlins 20 on the steel structure inclined beams 10, and then the energy-saving self-insulating integrated roof panels 30 are laid, wherein the energy-saving self-insulating integrated roof panels 30 and the cold-rolled thin-walled steel purlins 20 are welded or fastened by bolt assemblies 21. After installation, the energy-saving self-insulating integrated roof panels 30 are ensured to be secure.

[0033] Energy-saving self-insulating integrated roof panel 30, reference Figures 1 to 5 The integrated roof panel includes a corrugated steel plate 31, a foam insulation layer 32 and a high-strength concrete layer 33 from top to bottom. The corrugated steel plate 31 is made of a thin-walled steel plate, which is formed by pressing and has a color coating on its upper surface. The color coating has the comprehensive advantages of rust prevention, corrosion resistance and aesthetics.

[0034] The overlapping parts on both sides of the integrated roof panel are provided with a tongue-and-groove design for interlocking connection 37. The tongue-and-groove design improves the splicing effect of the splicing seams of the two roof panels, especially the leak-proof effect.

[0035] The foam insulation layer 32 is formed by spraying polyurethane foam material on the back of the profiled steel plate and then plastic forming the foam insulation layer 32. The thickness of the foam insulation layer is about 5 cm, which has sufficient heat insulation effect.

[0036] The best design of the foamed insulation layer is of equal thickness, that is, the foamed insulation layer has the same profile as the corrugated steel sheet, but the difference is that the foamed insulation layer is thicker than the corrugated steel sheet.

[0037] A groove having a trapezoidal cross section is formed on the lower surface of the foamed thermal insulation layer.

[0038] The high-strength concrete layer 33 is arranged below the foam insulation layer, and a steel truss 34 is laid in the above-mentioned groove, and the steel truss 34 is a triangular steel truss. Below the steel truss is a steel mesh 35, which can also be a steel mesh, arranged in the high-strength concrete layer.

[0039] The high-strength concrete layer includes a lower flat plate portion and an upwardly protruding rib portion 331 . This structure significantly increases the bearing capacity of the high-strength concrete layer.

[0040] A connection angle bracket 36 is provided on the back of the energy-saving self-insulating integrated roof panel 30. The connection angle bracket is preferably a cut angle steel piece, and the connection angle bracket is welded and fixed to the above-mentioned wire mesh or steel mesh to form a whole. The connection angle bracket is provided with bolt holes and is fixed to the purlin by fasteners. Therefore, the roof structure also has the advantage of fast construction speed.
