Suspended ceiling structure for mobile house

[0020] Embodiment 1: As shown in FIG. 1, the ceiling slat 1 includes a horizontal panel 11 and a connecting portion 12 extending upward from the left and right sides of the horizontal panel 11. The connecting portion 12 on each side is in an inverted L shape and is composed 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. Among them, the vertical plate surfaces 121 of the connecting parts 12 on the left and right sides have the same height to facilitate on-site installation and factory production. The widths a and c of the horizontal plate surfaces 122 on both sides can be the same or slightly longer. During installation, as shown in FIG. 5, the adjacent ceiling slats 1 are overlapped with each other through adjacent horizontal plate surfaces 122 to be spliced ​​together.

[0021] Embodiment 2: As shown in Figure 2, the structure of the ceiling slat 1 is basically the same as the embodiment, and it also includes a horizontal panel 11 and a connecting portion 12 extending upward from the left and right sides of the horizontal panel 11. The difference is: The outer end of the transverse plate surface 122 of one side of the connecting portion 12 is also provided with a rib 123 extending vertically downward to form an inverted U shape. The width a of the lateral board surface 122 on one side with the rib 123 is greater than or equal to the sum of the width c of the lateral board surface 122 on the other side and the thickness of the vertical board surface 121, and the side with the rib 123 The vertical board surface 121 is slightly higher than the other side vertical board surface 121, so that the one side connecting portion 12 of a ceiling slat 1 with a rib 123 can be overlapped with the adjacent ceiling slat 1 without a rib 123. On the connecting portion 12, the bottoms of two adjacent ceiling slats 1 after overlap are located on the same plane. During installation, as shown in FIG. 6, the inverted U-shaped connecting portion 12 of the ceiling slat 1 is buckled on the inverted L-shaped connecting portion 12 of the rib 123 of the adjacent ceiling slat 1.

[0022] The ceiling slats 1 of the above two structures can be formed by bending 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 grooves enclosed by the horizontal panel 11 and the vertical plate surfaces 121 on the left and right sides can be filled with polyurethane, polystyrene or other thermal insulation materials. During installation, one of the ceiling slats 1 can be used alone, or mixed. The optimal size setting of the ceiling slats 1 is: a+b=K/n, where: a is the width of the longer side of the horizontal panel 122, b is the width of the horizontal panel 11, and K is the standard of the mobile house Modulus (such as 1K=1820 mm, slightly different for each manufacturer), n is the number of ceiling slats within the standard modulus 1K of the mobile house.

[0023] In the existing mobile houses, the columns are usually back-to-back double C-shaped steel. Because the C-shaped steel columns are wider than the wall panels, the protruding curled part causes a gap between the floor panel and the wall surface. For this reason, the present invention The ceiling structure may further include two edge trimming strips 2 located at the outermost ends on the left and right sides of the plurality of ceiling slats 1. As shown in Figure 3, the cross section of the edge receiving strip 2 includes a vertical side 21 and a horizontal side 22 forming an L shape, a vertical folding side 23 extending upward along the end of the horizontal side 22, and The top of the vertical folded edge 23 is a horizontal folded edge 24 extending horizontally inward. As shown in FIG. 5 or FIG. 6, the horizontal folding edge 24 of the edge receiving strip 2 is overlapped under the horizontal transverse board surface 122 of the end ceiling slat 1, and the vertical edge 21 of the edge receiving strip 2 is connected to the movable house. On the wall. The length of the edge trim 2 can be set between the adjacent columns, which can effectively block the gap between the floor panel and the wall surface, so that the sound insulation and heat insulation effect of the suspended ceiling structure is better.

[0024] The installation method of the present invention for the suspended ceiling structure of the mobile house is as follows:

[0025] 1) After the main structure of the mobile house is installed, leaning on the front wall of the mobile house, put the two ends of the edge trim 2 directly on the protruding bottom of the roof truss or floor beam 3 of the mobile house.

[0026] 2) A ceiling slat 1 is laid on the end edge trim 2 through the joint 12, and its two ends are directly placed on the protruding bottom of the roof truss or floor beam 3 of the mobile house.

[0027] 3) The suspended ceiling slats 1 are overlapped with each other through the joint 12 to form the main suspended ceiling structure.

[0028] 4) When the ceiling slat 1 is laid on the back wall, another end edge strip 2 is placed against the rear wall of the mobile house and directly placed on the adjacent roof truss or floor beam 3 protruding curling edge at the bottom of the mobile house. on.

[0029] 5) Adjust the width between the edge receiving strips 2 and the ceiling slats 1 and the width between the ceiling slats 1 to make the ceiling surface dense and seamless.
