[0002] Small temporary buildings such as project departments of construction projects are currently mainly prefabricated houses or container-type temporary buildings. Although they can be reused, their appearance and shape are limited. In addition, the structure and connection method of the roof of the above-mentioned small temporary buildings are relatively simple, so the stability of the connection is not good, resulting in low efficiency of disassembly and reassembly during construction. In addition, the roof will be contaminated by glue due to glue application. If the roof system is to be disassembled, the glued parts must be cut, and glue must be applied again when reassembling, which is cumbersome and delays the construction progress.

DETAILED DESCRIPTION

[0027] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0029] like Figure 1 and 3 As shown, the outer side of the outer pressure plate 21 is covered with a roof buckle cover. It should be noted that a first roof buckle cover 211 and a second roof buckle cover 212 are respectively provided on the outer pressure plate 21 at the roof and the ridge.

[0030] Among them, an aluminum veneer is set at the joint position of the roof buckle cover, and the inner periphery is evenly coated with building sealant. The thickness of the aluminum veneer is 2mm.

[0031] like Figure 1 and 3 As shown, the inner pressure plate 23 is covered with an inner buckle cover 231 on the outside, and this buckle cover can be removed if there is a suspended ceiling inside the building.

[0032] In this embodiment, the unit plate 1 is layered from top to bottom with an upper aluminum plate 11 and a lower aluminum plate 13, the inner walls of the upper aluminum plate 11 and the lower aluminum plate 13 are respectively attached to the outer surfaces of both sides of the frame, and an insulation layer 12 is arranged between the upper aluminum plate 11 and the lower aluminum plate 13 to improve the energy saving effect, and the insulation cotton and the aluminum plate are fixed with rock wool nails during assembly. Among them, the thickness of the upper aluminum plate 11 is 3mm, the thickness of the lower aluminum plate 13 is 2mm, which can be used as an insulation aluminum plate, and the insulation layer 12 is 100mm thick insulation cotton.

[0033] like Figure 4As shown, an inner buckle portion connected to the second frame 62 is provided in the upper unit panel 1, and the inner buckle portion is concave so that the thickness of the insulation layer 12 in this area is reduced, and an installation gap is provided between the inner buckle portion and the end of the upper unit panel 1, and a first square tube 65 is connected to the side end surface of the second frame 62, and the first square tube 65 is arranged in the area where the thickness of the insulation layer 12 is reduced, so as to increase the strength of the inner buckle portion of the upper unit panel 1; the end of the lower unit panel 1 and its third frame 63 extend into the inner buckle portion of the upper unit panel 1, and the installation portion of the second frame 62 extends out of the upper unit panel 1 and is embedded in the third frame 63, so that the second frame 62 and the third frame 63 are connected to each other.

[0034] like Figure 5 As shown, the fourth frame 64 in the unit panel 1 at the eaves is spaced apart from the end of the unit panel 1, and the fourth frame 64 is connected to the outer opening 7 of the roof at its installation portion extending outdoors, and the outer opening 7 of the roof also has a water collection function and can be used as a gutter.

[0035] like Figure 4-5 As shown, in this embodiment, the ends of the upper unit panels 1 and the ends of the unit panels 1 at the eaves are provided with sealing aluminum plates 14 to guide rainwater on the roof. The thickness of the sealing aluminum plates 14 is 2 mm.

[0036] like Figure 1 and 3 As shown in FIG. 5 , a sealing tape 5 is provided on the inner wall of the connecting portion of the unit panel 1 and is in contact with the outer surface of the roof frame 6 .

[0037] like Figure 6-9 As shown, the roof frame 6 of this embodiment is provided with a second square tube 601 made of aluminum alloy inside, and the end of the second square tube 601 can be connected to the folded edge of the roof frame 6 through an aluminum angle code, as shown in FIG. Figure 8 .

[0038] Moreover, the angles at the folded edges of the roof frame 6 can also be connected by aluminum corner brackets, as shown in the figure. Fig. 9 .

[0039] Among them, when the side length of the roof frame 6 is greater than 600mm, the reinforcing rib 602 needs to be fixed. The reinforcing rib 602 is made of aluminum alloy profile, and the spacing between the reinforcing rib 602 and the second square tube 601 is not greater than 300mm; the reinforcing rib 602 is fixed with aluminum welding nails, but during processing, it should be ensured that the outer surface of the aluminum plate does not deform or fade, and the fixation should be firm. Aluminum planting nails must be used when welding aluminum plates; the welding voltage of aluminum planting nails should be above 90V, and they should be welded perpendicular to the aluminum plate, with an allowable deviation of ±1°

[0040] The arrangement of the reinforcing rib 602 and the connection method with the aluminum plate are shown as follows: Figure 7Note that the starting position of the reinforcement rib 602 should be away from the aluminum plate to avoid the aluminum corner. The reinforcement rib 602 is arranged perpendicular to the long side. When both sides are greater than 200mm, the ribs are arranged in two directions (the short side direction is the main reinforcement rib arrangement).

[0041] like Figure 1 , 3 As shown in Figure 5, in this embodiment, the supporting structure 3 includes a steel square tube 31 directly or indirectly arranged on the main steel structure 4, and the steel square tube 31 is bolted to a connecting plate 32 on the side in the opposite direction, and the first frame 61 is connected through the connecting plate 32 to fix the adjacent first frame 61 together by bolts at the same time; the main steel structure 4 can also be provided with a steel pedestal 33 for connecting with the steel square tube 31, and the steel pedestal 33 is mainly formed by splicing a first steel plate and a second steel plate, the first steel plate is used to connect with the main steel structure 4, and the second steel plate forms a connecting platform on its top for supporting the steel square tube 31.

[0042] Therefore, based on the above content, the roof system of this embodiment and the main steel structure 4 of the building to which it is connected are preferably connected and fixed with bolts to avoid the situation where a large amount of welding is required during the on-site assembly of traditional temporary buildings, thereby reducing the requirements for construction and avoiding the need to cut and re-weld when the on-site welding position and the connection position designed according to the specific site are wrong.

[0043] At the same time, all panels of the roof system can be disassembled and rebuilt in a different location within the service life. Except for embedded parts, local screws, bolts and other small hardware, almost all materials can be reused. According to the design service life of 25 years, the temporary building is used for 3-5 years at a time, and can be reused 5-8 times. Although the one-time investment is slightly higher than that of ordinary temporary buildings, it can be recycled for a long time, and the overall cost is greatly reduced.

[0044] The above embodiment is only a preferred technical solution of the present invention. Those skilled in the art should understand that the technical solutions or parameters in the embodiments can be modified or replaced without departing from the principle and essence of the present invention, and all should be included in the protection scope of the present invention.
