Description

Technical Field

[0001] The utility model relates to a prefabricated house cover plate. Background Art

[0002] As we all know, glass wool or rock wool has been widely used as roof covering panels in modern buildings due to its light weight and good performance. The roof covering panels currently on the market are made by laying metal sheets on both sides of a piece of foam cotton. Its structure is simple, but due to the lack of a specific supporting structure, it lacks rigidity and is prone to structural deformation and damage. In addition, it cannot achieve a waterproof effect after assembly, and rainwater can easily fall into the house from the gaps in the screw holes and the gaps in the assembly. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a prefabricated house cover.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A prefabricated house cover comprises a cover beam, supporting sub-beams equidistantly welded on the cover beam, thin steel plates laid on the cover beam and the supporting sub-beam, a fixing seat fixed on the cover beam by two screws and used for squeezing and fixing two adjacent thin steel plates, a flame retardant layer laid on the surface of the thin steel plate, an insulation plate laid on the surface of the flame retardant layer and separated by the fixing seat, a waterproof layer laid on the insulation plate, a stainless steel plate laid on the surface of the waterproof layer and abutting against the fixing seat at both ends, and a locking member mounted on the fixing seat and used for fixing the stainless steel plate.

[0006] Preferably, the fixing seat comprises a sheet steel bar, mounting feet equidistantly welded below the sheet steel bar and capable of abutting against the cover plate cross beam, and a cylindrical portion integrally formed on the sheet steel bar.

[0007] Preferably, the flame retardant layer is a flame retardant non-woven fabric.

[0008] Preferably, the insulation board is a foam board.

[0009] Preferably, the waterproof layer is a polyurethane waterproof layer.

[0010] Preferably, the stainless steel thin plate includes a stainless steel thin plate body, a semicircular protrusion formed by stamping on the stainless steel thin plate body, an inner overlapping portion formed by bending on one side of the stainless steel thin plate body and capable of covering the fixed seat, and an outer overlapping portion formed by bending on the other side of the stainless steel thin plate body and capable of covering the inner overlapping portion of an adjacent stainless steel thin plate.

[0011] Preferably, the locking assembly includes a spherical clamping strip, a clamping plate extending downward from the spherical clamping strip, and a locking stud assembled on the clamping plate.

[0012] The beneficial effects of the utility model are:

[0013] 1. Stable structure: The fixing seat is used as the main component to separate the installation space and lay the flame retardant layer, insulation board, waterproof layer and stainless steel sheet in sequence. It is also conducive to fixing the stainless steel sheet, ensuring the structural stability of the cover plate and improving the bearing capacity of the overall roof;

[0014] 2. Fireproof performance: Using flame-retardant non-woven fabric as the flame-retardant layer can effectively improve the fireproof performance of the roof and increase the safety of the building;

[0015] 3. Thermal insulation: Using foam board as the thermal insulation layer can reduce heat conduction, improve the thermal insulation performance of the building, and reduce energy consumption;

[0016] 4. Waterproof performance: The use of polyurethane waterproof layer can effectively prevent moisture penetration, protect the building structure and extend the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0023] Example

[0024] A prefabricated house cover, such as Figure 1As shown, it includes a cover beam 1, a supporting sub-beam 2 equidistantly welded on the cover beam 1, a thin steel plate 3 laid on the cover beam 1 and the supporting sub-beam 2, a fixing seat 4 fixed on the cover beam 1 by two screws and used for squeezing and fixing two adjacent thin steel plates 3, a flame retardant layer 5 laid on the surface of the thin steel plate 3, a heat preservation plate 6 laid on the surface of the flame retardant layer 5 and separated by the fixing seat 4, a waterproof layer 7 laid on the heat preservation plate 6, a stainless steel thin plate 8 laid on the surface of the waterproof layer 7 and abutting against the fixing seat 4 at both ends, and a locking member 9 mounted on the fixing seat 4 and used for fixing the stainless steel thin plate 8.

[0025] like Figure 2 As shown, the fixing seat 4 includes a sheet steel bar 41, mounting feet 42 equidistantly welded below the sheet steel bar 41 and capable of abutting against the cover beam 1, and a cylindrical portion 43 integrally formed on the sheet steel bar 41. Specifically, the sheet steel bar 41 spans across a number of cover beams 1, and abuts against the cover beam 1 through the mounting feet 42, and then is fixed by driving screws, which facilitates the fixing of the thin steel plate 3, can separate the installation space for sequentially closely laying the flame retardant layer 5, the insulation board 6, the waterproof layer 7 and the stainless steel sheet 8, and is also conducive to fixing the stainless steel sheet 8.

[0026] like Figure 3 As shown, the stainless steel sheet 8 includes a stainless steel sheet body 81, a semicircular protrusion 82 formed by stamping on the stainless steel sheet body 81, an inner lap portion 83 formed by bending on one side of the stainless steel sheet body 81 and capable of covering the fixing seat 4, and an outer lap portion 84 formed by bending on the other side of the stainless steel sheet body 81 and capable of covering the inner lap portion of the adjacent stainless steel sheet 8. Specifically, the semicircular protrusion 82 separates the stainless steel sheet body 81 into equidistant drainage grooves.

[0027] like Figure 4 As shown, the locking member 9 includes a spherical clamping strip 91 , a clamping plate 92 extending downward from the spherical clamping strip 91 , and a locking stud 93 assembled on the clamping plate 92 .

[0028] In this embodiment, the flame retardant layer 5 is a flame retardant non-woven fabric.

[0029] In this embodiment, the heat-insulating board 6 is a foam board.

[0030] In this embodiment, the waterproof layer 7 is a polyurethane waterproof layer.

[0031] See also Figure 5In this scheme, the assembly process between the stainless steel sheet 8, the fixing seat 4 and the locking member 9 is abcd as shown in the figure. The inner lap portion of the first stainless steel sheet is mounted on the cylindrical portion of the first fixing seat, and then the outer lap portion of the second stainless steel sheet is mounted on the surface of the inner lap portion of the first stainless steel sheet, and the outer lap portion is further bent to make it fit more closely to the inner lap portion. The subsequent stainless steel sheets are laid in this assembly method in sequence; after the laying of the stainless steel sheets is completed, the spherical clamping strips in the locking member 9 are buckled and installed on the cylindrical portion, while covering the inner and outer lap portions of the adjacent stainless steel sheets, so that the clamping plate is parallel to the sheet steel strip of the fixing seat 4, and finally fixed by driving the locking studs. Specifically, after assembly through the above steps, the stainless steel sheet can be stably installed and is conducive to preventing further water seepage.
