Description

Technical Field

[0001] The utility model relates to a movable house, in particular to a roof structure of a modular movable house. Background Art

[0002] In order to store tools, machines, lawn maintenance equipment, entertainment equipment, sports equipment, consumables and other items, people have invented various portable houses. Portable houses usually include wall panels, doors, floor panels and roofs. The wall panels, doors, floor panels and roofs often include one or more parts connected to each other. After these wall panels, doors, floor panels and roofs are installed, they constitute a portable house. The roof is one of the important components of a portable house, and the firmness of its assembly structure has an important impact on the stability of the overall structure of the portable house. For traditional wooden portable houses, the beam support frame and the roof panel are both made of wooden structure. The roof panel is fixed to the beam support frame by screws. Although the fixed structure is relatively firm, it is time-consuming to install and disassemble. For metal portable houses, although the overall structure is relatively stable, the cost is relatively high. The roof and the beam support frame and the roof and the wall panels are tightly assembled by many screws or bolts, and the installation and disassembly are also time-consuming and laborious. Although the existing plastic mobile houses have the advantages of light structure and easy installation, they usually have the defect of not being strong enough. For example, the roof structure only connects and fixes the roof on the beam support frame, and the installation structure is not stable enough. When encountering strong winds outdoors, the roof may be opened, causing the items inside the house to get wet and damaged. In addition, the existing roofs usually adopt flat roofs. When the roof is composed of multiple panels, rainwater will flow into the house through the joints on rainy days. In summary, the roof structure of the existing modular mobile houses needs to be further improved. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a wall panel assembly structure which has a firm structure and is convenient to install and disassemble in view of the above-mentioned existing technical status.

[0004] The technical solution adopted by the utility model to solve the above technical problems is: a roof structure of a modular mobile house, including a roof and a beam support frame for supporting the roof, and triangular lintels are arranged on two opposite sides below the roof, characterized in that: the beam support frame includes a beam center column and a beam cross piece, the beam center column is arranged in parallel with the triangular lintel, the beam cross pieces are distributed at intervals on the beam center column, the roof is covered on the beam support frame and fixed on the beam center column and the beam cross piece, and a mutually cooperating limiting structure is provided between the roof and the triangular lintel.

[0005] In order to fix the center column of the beam to the wall panel, the end of the center column of the beam is connected and fixed to the wall panel of the movable house through a first connecting piece.

[0006] In order to ensure that the center beam does not exceed the length of the packaging box, the center beam has a folding structure in the middle so that the center beam can be folded in half when disassembled. Therefore, when the roof is under pressure, the folded part of the center beam can also disperse the weight.

[0007] In order to prevent the roof from sliding down along the triangular lintel, a limiting protrusion is convexly provided on the top of the triangular lintel, and a limiting groove is provided at a corresponding position of the bottom of the roof. The limiting protrusion is inserted into the corresponding limiting groove to form the limiting structure.

[0008] In order to better limit the cooperation between the roof and the triangular door lintel, a downward-opening slot is formed at the bottom of the roof corresponding to the upper edge of the triangular door lintel, the upper edge of the triangular door lintel is inserted into the slot, and the limiting groove is arranged in the slot.

[0009] The roof can have a variety of structures. Preferably, the roof includes a roof middle plate and a roof side plate. The roof side plates have two pieces and are respectively arranged on both sides of the roof middle plate. The roof middle plate and the roof side plates are both limited by the triangular lintel through the limiting structure, and the roof middle plate and the roof side plates are both fixed on the beam support frame.

[0010] Further preferably, the beam crosspiece includes a beam middle crosspiece and a beam side crosspiece, the two ends of the beam middle crosspiece are connected and fixed to the triangular door lintel, the roof middle plate and the roof side plate are connected and fixed through the beam side crosspiece adjacent to the beam middle crosspiece, and the two ends of the beam side crosspiece are fixed to the roof side plate or to the triangular door lintel. In this way, the connection structure of the movable house roof can be made more firm by connecting and fixing the beam middle crosspiece and the beam side crosspiece.

[0011] Further preferably, the roof middle plate is a flat blow-molded plate in the unfolded state, and in the installed state, the middle of the roof middle plate is bent into a roof peak that matches the triangular door lintel and is fixed on the beam support frame. In this way, the middle of the roof middle plate has a soft material structure, which is convenient for the roof middle plate to be flipped downward when installed.

[0012] In order to prevent rainwater from entering the mobile house through the roof, when the roof is installed, the top surfaces of the roof middle plate and the roof side plates form a stepped structure that gradually descends from the middle to both sides.

[0013] In order to fix the roof side panels on the wall panels, positioning grooves are arranged at intervals along the length direction at the lower edge of the roof side panels, and fixing connecting pieces are installed in the positioning grooves. The roof side panels are fixed to the wall panels through the fixing connecting pieces.

[0014] Compared with the prior art, the utility model has the advantages that the beam support frame, the beam center column and the triangular door lintel of the modular movable house roof structure are arranged in parallel, and the beam cross pieces are distributed on the beam center column at intervals. The roof is not only fixed on the beam center column and the beam cross piece, but also has a mutually coordinated limiting structure with the triangular door lintel, so that the installation structure of the roof is more solid, and the roof and the beam support frame and the triangular door lintel adopt a detachable installation structure, which is very convenient to install and disassemble.

[0023] The matching structure of the roof middle plate 11 and the roof side plate 12 with the triangular door lintel is as follows:

[0024] A downward-opening slot 14 is formed at the bottom of the roof 1 at a position corresponding to the upper edge of the triangular lintel 3, and the upper edge of the triangular lintel 3 is inserted into the slot 14, that is, the edge of the roof 1 can wrap the upper edge of the triangular lintel 3. In addition, a limiting protrusion 31 is convexly provided on the top of the triangular lintel 3, and a limiting groove 13 is provided at the corresponding position of the bottom of the roof 1. The limiting groove 13 is provided in the slot 14, that is, the slot 14 is further deepened to form the limiting groove 13, and the limiting protrusion 31 is inserted into the corresponding limiting groove 13 to form a limiting structure. In this embodiment, the limiting protrusion 31 is a strip-shaped protrusion distributed at intervals, and the limiting protrusion 31 is inserted into the limiting groove 13 to prevent the roof 1 from sliding downward.

[0025] Combination Figure 4 As shown, the beam support frame 2 of this embodiment includes a beam center column 21 and a beam cross bar. The beam center column 21 is arranged in parallel with the triangular lintel 3, and the middle of the beam center column 21 has a folding structure so that the beam center column 21 can be folded in half when disassembled. The beam center column 21 adopts a folding structure, which can reduce its length by half and does not exceed the length of the packaging box. When the roof 1 is under pressure, the folding part can also disperse the weight. The two ends of the beam center column 21 are connected and fixed to the wall panel 6 of the mobile house through the connecting piece 4. The connecting piece of this embodiment is an injection molded part. The rectangular opening of the injection molded part is inserted into the square tube opening of the beam center column 21.
