Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a prefabricated building that can be folded to make it compact during storage and transportation, and that can be assembled into single-story, two-story, etc. structures at a construction site. It is related to.

(Prior art) As a conventional folding unit house, for example,
There is one as shown in Japanese Patent No.-2726. This is the first
1 and 12, and FIG. 11 is a perspective view of this folding unit house in an exploded state.
FIG. 2 is a partially cutaway side view of this folding unit house in a folded state. To explain this with reference to the figure, the main column frame 2 is pivoted on both sides of the floor unit 1 so that it can rise and fall freely with respect to the floor unit 1. When the main column frame 2 is installed and the main column frame 2 is in the upright state, the main column frame 2
The lower end is fixed to the side of the floor unit 1 with fasteners such as bolts, and the four corners of the roof unit 4 are fixed to the -F section of the main column frame 2 with fasteners such as bolts to secure the frame of the house. In a configuration in which a blind wall 5 is attached to the main column frame 2, and a middle column 8, a large window wall 7, an entrance wall 6, etc. are attached to the other peripheral surfaces, the main column frame 2 is attached to the main column frame 2. 2 has a structure in which side columns 2' of L-shaped steel are arranged on both sides, and horizontal beams 2'' are connected above and below these side columns 2', and the roof unit 4 has a peripheral member made of U-shaped steel on the periphery. 4' is arranged,
This peripheral member 4' has an L-shaped tongue piece 4'' arranged downwardly at the lower part thereof, and when the house is folded, the L-shaped tongue piece 4'' of the roof unit 4 is connected to the main pillar frame. By engaging with the side pillars 2' of 2, an appropriate space is formed between the floor unit 1 and the main pillar frame 2, and the entrance/exit wall 6, large window wall 7, middle pillar 8, etc. are installed in this space. This is intended to prevent the roof unit 4 from shifting laterally during storage and transportation by engaging the side pillars 2' and the L-shaped tongues 4''.

[Problem to be solved by the invention]

However, since the roof unit 4 in the conventional folding unit house has an L-shaped tongue piece 4# connected downward to the lower part of the peripheral member 4' made of U-shaped steel, the main pillar does not move when folded. Although it is possible to engage the frame 2, there is no groove for fitting and engaging the upper ends of the entrance/exit wall 6, large window wall 7, middle pillar 8, etc. when attaching them during assembly, and these When fixing the upper end to the above I and the mold tongue piece 4' with bolts,
Since bolt insertion holes are provided in the above-mentioned tongue-shaped tongue piece 4'' for fixation, there is a problem in that rainwater does not enter the interior through the bolt insertion holes, and the floor unit 1 has the following problems:
The problem is that the lower ends of the middle pillar 8, the large window wall 7, the entrance wall 6, etc. cannot be easily engaged because the grooves that engage the lower ends of the middle pillar 8, the large window wall 7, the entrance wall 6, etc. are not provided on the side surfaces (finger parts). In addition, the main column frame 2 has a structure in which side columns 2' of L-shaped steel are simply arranged on both sides, and horizontal rods 2# are connected above and below these side columns 2', so that it has no torsion in terms of strength. Furthermore, if a unit house of the same type is stacked on top of a one-story unit house to create a two-story structure, a separate member is required to connect the two unit houses. However, there were various problems such as not only a complicated structure but also poor workability.

An object of the present invention is to provide an assembled building that solves various problems such as those of the conventional example.

[Means for Solving the Problems] The present invention aims to solve the above-mentioned problems, and the present invention has a floor frame and a floor frame, and the lower end portions thereof are pivotally mounted on the left and right sides of the front and rear finger portions of the floor frame so as to be able to rise and fall. The left and right end frames are made of pillar members that are fixed with fasteners such as bolts, and the four corners are fixed to the upper ends of the pillar members that form this upright end frame with fasteners such as bolts. The floor frame is a prefabricated building consisting of a roof frame, in which the floor frame forms a frame body with front and rear girder members having a desired cross-sectional shape and left and right girder members, and panels and studs are attached to the outer surface of the girder member. A concave groove is provided in which the lower end of the girder member engages with the side edge of the column member forming the end frame when collapsed, and the lower end of the column member forming the end frame is rotatably pivoted at both ends of both girder members. At the same time, a mounting plate is provided for fixing the lower end of the column member in an upright state, and the upper surface of both ends of the front and rear girder members forming the roof frame is attached to the lower surface of both ends of the girder member. A connecting member is provided in a screw hole provided in the roof frame, through which a bolt is inserted and fastened when building a two-story building. First and second engaging pieces are provided at a required interval to engage the upper ends of the column members, panels, studs, etc. forming the end frame facing downward on the lower edge, and also on the outer surfaces of the end members. In addition to providing a rain gutter, an engaging piece is provided on the outer lower edge of the pillar member that faces downward and engages with the upper end of the column member forming the gable frame from the inner surface, and a two-story structure is provided on the upper surface of both ends of the girder member. The roof frame is characterized by having a screw hole for screwing a bolt inserted through a connecting member provided in the floor frame, and a protrusion for positioning the first and second floors and for hanging a rope for lifting the roof frame. It is something to do.
