Detailed ways

Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

As shown in Fig. 4, the suspended ceiling structure used in the mobile room of the present invention is overlapped with each other successively by a plurality of suspended ceiling slats 1 and erected and arranged between two floor beams or roof beams 3 protruding curlings at the bottom, the suspended ceiling panels Article 1 can adopt the following two structures:

Embodiment 1: As shown in FIG. 1 , the ceiling batten 1 includes a horizontal panel 11 and connecting portions 12 extending upward from the left and right sides of the horizontal panel 11 . Each connecting portion 12 is in an inverted L shape and consists of a vertical plate surface 121 extending upward along the end of the horizontal panel 11 and a horizontal plate surface 122 extending horizontally outward along the top of the vertical plate surface 121 . Wherein, the heights of the vertical plate surfaces 121 of the connecting parts 12 on the left and right sides are the same to facilitate on-site installation and factory production, and the widths a and c of the horizontal plate surfaces 122 on both sides can be the same or slightly different. During installation, as shown in FIG. 5 , the adjacent ceiling battens 1 are spliced together by overlapping the adjacent horizontal board surfaces 122 .

Embodiment 2: As shown in FIG. 2 , the structure of the ceiling slat 1 is basically the same as that of the embodiment, and also includes a horizontal panel 11 and connecting parts 12 extending upward from the left and right sides of the horizontal panel 11 . The difference is that, The outer end of the transverse plate surface 122 of one side connecting portion 12 is also provided with a rib 123 extending vertically downwards to form an inverted U shape. The width a of the horizontal plate surface 122 on one side with the rib 123 is greater than or equal to the sum of the width c of the transverse plate surface 122 on the other side and the thickness of the vertical plate surface 121, and the side with the rib 123 The riser surface 121 is slightly higher than the riser surface 121 on the other side, so that the connecting portion 12 on one side of a certain ceiling slat 1 with the rib 123 can be overlapped with the side of the adjacent ceiling slat 1 without the edge 123 On the joining portion 12, the bottoms of two adjacent ceiling slats 1 are located on the same plane after being overlapped. During installation, as shown in FIG. 6 , buckle the inverted U-shaped connecting portion 12 of the ceiling slat 1 on the inverted L-shaped connecting portion 12 of the rib 123 without the adjacent ceiling slat 1 .

The ceiling slats 1 of the above two structures can be bent from thin metal plates such as color-coated thin steel plates, thin stainless steel plates, thin aluminum plates, or thin copper plates. In order to achieve better heat and sound insulation effects, the ceiling slats 1 The groove surrounded by the horizontal panel 11 and the vertical panels 121 on the left and right sides can be filled with polyurethane, polyphenylene or other thermal insulation materials. One of the ceiling slats 1 can be used alone or in combination during installation. The optimal size of the ceiling batten 1 is set to: a+b=K/n, wherein: a is the width of the horizontal panel surface 122 on the longer side, b is the width of the horizontal panel 11, and K is the standard of the prefabricated house Modulus (such as 1K=1820 mm, each manufacturer is slightly different), n is the number of ceiling slats within the standard modulus 1K range of the mobile house.

In the existing prefabricated houses, the columns usually adopt double C-shaped steel back-to-back. Since the C-shaped steel columns are wider than the wall panels, the protruding curling part will form a gap between the floor panel and the wall surface. Therefore, the present invention The suspended ceiling structure may also include two edge strips 2 located at the left and right outermost ends of the plurality of suspended ceiling battens 1 . As shown in Figure 3, the cross section of the edge trim strip 2 includes a vertical edge 21 and a horizontal edge 22 forming an L shape, a vertical edge 23 extending upward along the end of the horizontal edge 22, and a vertical edge 23 extending upward along the The top of the vertical fold 23 is a horizontal fold 24 extending horizontally inward. As shown in Figure 5 or Figure 6, the horizontal fold 24 of the edge trimming strip 2 is overlapped below the horizontal horizontal plate surface 122 of the end ceiling slat 1, and the vertical edge 21 of the edge trimming strip 2 is in contact with the prefabricated room. The wall is attached. The length of the edge strip 2 can be set between adjacent columns, which can effectively block the gap between the floor panel and the wall, so that the sound insulation and heat insulation effect of the suspended ceiling structure is better.

The installation method of the suspended ceiling structure that the present invention is used for prefabricated house is as follows:

1) After the main structure of the mobile house is installed, first lean on the front wall of the mobile house to directly place the two ends of an end edge strip 2 on the protruding curl at the bottom of the adjacent roof truss or floor beam 3 of the mobile house.

2) A ceiling slat 1 is placed on the edge trimming strip 2 through the connecting portion 12, and its two ends are directly placed on the protruding curling at the bottom of the roof truss or floor beam 3 adjacent to the mobile house.

3) The suspended ceiling slats 1 are overlapped with each other through the connecting portion 12 to form the main structure of the suspended ceiling.

4) When the ceiling slats 1 are laid on the back wall, use an end trim strip 2 to lean against the two ends of the back wall of the mobile house and place it directly on the protruding curling at the bottom of the roof truss or floor beam 3 adjacent to the mobile house superior.

5) Adjust the width between the end edge strip 2 and the ceiling slat 1 and the width between the ceiling slat 1 so that the ceiling surface is dense and seamless.
