Description

Technical Field

[0001] The present invention relates to the field of movable house structures, and more particularly to a folding structure for a modular double-story movable house. Background Art

[0002] Currently, temporary housing facilities mainly include tents and movable houses in various structural forms. Movable houses can be divided into three major categories according to different structural forms, namely: container type, vehicle-mounted type, and assembled type. Although tents have the advantages of being lightweight and easy to install, they are poor in comfort, environmental adaptability, and durability, and are not conducive to long-term use in harsh natural environments. Existing movable houses in structural forms, although having better performance than tents, either have problems such as inconvenient transportation and cumbersome erection processes, or have defects such as high costs and inability to be mass-produced. This is not conducive to the placement of movable houses in post-disaster resettlement of residents, accommodation for field workers, and deployment during field training of troops. Whether it is the affected people, field workers, or military camps, what they urgently need is a movable house structure that is easy to transport, lightweight to carry, simple and fast to install, has more usable area, can adapt to various terrains and environments, and can be reused and easily maintained. Summary of the Invention

[0003] The object of the present invention is to provide a movable house structure that is quick to disassemble and assemble, convenient for storage and transportation, strong in adaptability, wide in application range, and capable of continuous and efficient overall folding.

[0004] The object of the present invention is implemented by the following technical solutions:

[0005] A folding structure for a modular double-story movable house, comprising: at least one foldable frame structure unit. A single said frame structure unit includes upper and lower layers, and the horizontal cross-section of each layer is square. The columns in the middle of the frame structure unit are connected to the left and right side columns through beams. The left and right columns of the frame structure unit are folded towards the middle column. The longitudinal cross-section shape of each layer is square. Each adjacent two units of the frame structure unit are connected by sharing the same middle bay frame. The rear side of the frame structure unit folds towards the front side of the frame structure unit.

[0006] Further, the horizontal cross-section of a single said frame structure unit is two identical squares up and down.

[0007] Further, the frame structure unit includes corner columns, sliding shaft columns, sliding columns, and beams; the upper and middle parts of the corner columns are respectively connected to the upper and lower parts of the sliding columns through beams;

[0008] Both the front side and the rear side of the sliding column are provided with grooves, which are connected to the sliding grooves of the sliding shaft column and can slide freely in the sliding grooves. The upper end of the sliding column is provided with positioning bolt holes for fixing during stopping. On the web of the sliding shaft column, there is a gap with a certain length and a certain width as the sliding rail of the sliding column. The upper end of the sliding shaft column is provided with positioning bolt holes for fixing during stopping.

[0009] Further, the connection between the beam and the left corner column can rotate within the plane from 0° to -90°, the connection between the beam and the right corner column can rotate within the plane from 180° to 270°, the connection between the beam and the left side of the sliding column can rotate within the plane from 90° to 180° and can also slide vertically within the plane, and the connection between the beam and the right side of the sliding column can rotate within the plane from 0° to 90° and can also slide vertically within the plane.

[0010] Further, the longitudinal section of a single said frame structure unit is two identical squares, one above the other.

[0011] Further, the upper part and the middle part of the corner column respectively have two interfaces in mutually perpendicular directions, and are respectively connected to the sliding columns in each direction through beams. There are two bolt holes respectively above and below the interface for the rotation and positioning of the beam. When the structure is in the contracted state, half of the volume of the beam can be embedded in the corner column.

[0012] Further, the upper part and the lower part of the sliding column respectively have an interface on the left and right sides. There are two bolt holes respectively above and below the interface for the rotation and positioning of the beam. When the structure is in the contracted state, half of the volume of the beam can be embedded in the sliding column.

[0013] Further, the upper left side and the lower left side of the beam respectively have a bolt hole, and the upper right side and the lower right side of the beam respectively have a bolt hole. When the structure is in the contracted state, the beam can be integrally embedded in the columns connected on the left and right.

[0014] After the structure is fully unfolded, the assembly of the slab beam, the floor slab and the roof slab is carried out. The two ends of the slab beam are inserted into the interfaces reserved in the upper part and the middle part of the sliding shaft column. The floor slab and the roof slab are respectively composed of six small plates. The plates are connected by hinges and can be folded into one small plate. There are grooves at the intersection of the hinges and the slab beam, which can smoothly install the plates on the slab beam. After folding, they can be placed together with the slab beam into the space reserved inside the folding house structure when it is fully folded during transportation.

[0015] Further, there are several said frame structure units. Several said structure units are arranged in a row in a strip shape, and adjacent two said structure units are connected by sharing the same middle truss frame. The middle truss frame is specifically composed of a middle column, a beam, a sliding shaft column and a sliding column.

[0016] The upper and middle parts of the middle column have interfaces in three directions, which are respectively connected to the sliding columns on the left, right and front sides through beams. There are two bolt holes above and below the interface for the rotation and positioning of the beams. When the structure is in the contracted state, half of the volume of the beam can be embedded in the middle column;

[0017] After several of the frame structure units are connected, they can still be stretched horizontally and vertically. Only by fixing all the columns on the longitudinal sliding grooves on the ground can the contracted overall frame structure be stretched into rows of houses. This structure greatly saves construction time and also saves a large amount of manpower and material resources.

[0018] Furthermore, the modular double-deck movable house folding structure further includes sliding grooves fixed on the ground, and the sliding grooves are connected to all the columns, facilitating the folding and unfolding of the structural units.

[0019] The beneficial effects brought by the technical solution provided by the embodiment of the present invention are as follows:

[0020] 1. It can solve the living problems of multiple people in a relatively short time, and has a wide range of applications, both for military and civilian use;

[0021] 2. Through the adjustment of the structure and materials, the present invention can be applicable to different regions and terrains, meeting the living and residential needs of users under different conditions;

[0022] 3. The space composition of the present invention is realized through folding. When the single structural unit is folded as a whole, it is in a bundle shape and occupies a small space, which is convenient for transportation and carrying, greatly saving manpower and material resources;

[0023] 4. When the structure of the present invention is unfolded, it is a double-deck house structure. Compared with similar folding house structures, it can provide more living area in the same or shorter construction time, and the space is spacious and bright, with better comfort;

[0024] 5. The components of the structure of the present invention are basically unified, which is convenient for replacement and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
