Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a prefabricated building that can be folded into a compact size during storage and transportation, and that can be easily assembled into -positive, double-positive, etc. at a construction site. It concerns the floor frame.

[Prior art]

For example, as a conventional folding unit house,
There is one as shown in Publication No.-272.6. This is as shown in Figures 11 and 12.
The figure is a perspective view of this folding unit house in an exploded state, and FIG. 12 is a partially cutaway side view of this folding unit house in a folded state. The main column frame 2 is pivoted to the floor unit 1 on both sides so that it can rise and fall freely, and when the main column frame 2 is in the upright state, the lower end of the main column frame 2 is fixed to the side surface of the floor unit 1 with bolts or the like. At the same time, the four corners of the roof unit 4 are fixed to the upper part of the main pillar frame 2 with fasteners such as bolts to form the frame of the house, and furthermore, the stomach wall 5 is attached to the main pillar frame 2, and In a configuration in which the center pillar 8, large window wall 7, entrance/exit wall 6, etc. are attached to other peripheral surfaces, the main pillar frame 2 has 1. The roof unit 4 has a structure in which side columns 2' made of shaped steel are arranged, and horizontal beams 2'' are connected above and below this side column 2', and the roof unit 4 has a peripheral member 4' made of U-shaped steel arranged around its periphery. , an L-shaped tongue piece 4' is connected downwardly to the lower part of this peripheral member 4', and when the house is folded, the L-shaped tongue piece 41 of the roof unit 4 is attached to the main pillar frame. By engaging with the side pillars 2' of 2, an appropriate space is formed between the floor unit l 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. When storing and transporting, the side pillar 2'
The purpose of this is to prevent the roof unit 4 from shifting laterally by securing the molded tongue pieces 4' together.

[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 can be engaged with the frame 2, there is no groove for fitting and securing the upper ends of the entrance 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-mentioned tongue piece 4'' with bolts, a bolt insertion hole is provided in the above-mentioned form 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 a problem that rainwater is not well protected from the rain.
Since there is no concave groove to engage the lower end of the
There is a problem in that the lower ends of these cannot be easily engaged, and the main column frame 2 simply has side columns 2' made of L-shaped steel on both sides, and horizontally above and below these side columns 2'. Since it has a structure in which the rods 2'' are connected, there is a problem that it is weak against torsion in terms of strength.Furthermore, when a unit house of the same type is stacked on top of a unit house assembled positively to make it a two-story structure, This requires a separate member to connect the two unit houses, which not only complicates the structure, but also poses various problems such as poor workability.

An object of the present invention is to provide a floor frame for a building that solves various problems such as those of the conventional example.

[Means to solve the problem]

The present invention aims to solve the above problem, and the lower end portions of the floor frame and the left and right sides of the front and rear girder portions are pivotally pivoted so as to be able to rise and fall freely, and are fixed with fasteners such as bolts in the upright state. An assembled building consisting of left and right gable frames formed of pillar members, etc. in an upright state, and a roof frame whose four corners are fixed to the upper ends of the column members forming the gable frames in an upright state with fasteners such as bolts. In the floor frame, a frame body is formed by front and rear girder members having a desired cross-sectional shape and left and right end members, and lower ends of panels, studs, etc. and end frames when collapsed are formed on the outer surface of the girder members. A concave groove is provided in which the side edge of the column member is engaged, and the lower end of the column member forming the end frame is rotatably pivoted to both ends of the girder members. A mounting plate is provided to fix the lower end, and bolts inserted at the time of the two-story building are inserted into the screw holes provided on the lower surface of both ends of the girder members that form the roof frame. The present invention is characterized in that it is configured by providing a connecting member for fastening the.

〔effect〕

As explained above, the present invention has a structure in which the lower end portions of the floor frame and the left and right sides of the front and rear girder portions are pivotally attached to the floor frame so as to be able to rise and fall freely, and are fixed with fasteners such as bolts in the upright state. In an assembled building consisting of left and right gable frames formed of column members, etc., and a roof frame whose four corners are fixed to the upper ends of the column members forming the gable frames in an upright state with fasteners such as bolts, the floor The frame includes front and rear finger members having a desired cross-sectional shape and left and right end members, and on the outer surface of the finger members, the lower ends of panels, studs, etc., and pillar members that form the end frame when collapsed. A concave groove is provided where the side edges engage, and the lower end of the column member forming the end frame is rotatably pivoted to both ends of both girder members, and the lower end of the column member in the upright state is fixed. A mounting plate is provided for the roof frame, and bolts are inserted into the screw holes provided on the lower surface of both ends of both girder members and on the upper surface of both ends of the front and rear finger members that form the roof frame when building a two-story building. Now that we have configured the connecting members to be fastened,
In other words, on the girder side of the floor frame, there is a recess that is used to hold the lower end of panels, studs, panels with window frames, door frames, etc. when assembled, and to receive the side edges of the column members that form the collapsed end frame when folded. Since the groove is provided, it is possible to easily and quickly attach the panels, studs, panels with window frames, door frames, etc. during assembly, as well as to facilitate the storage of prefabricated buildings assembled using this floor frame. When folding each member to reduce bulk during storage or transportation, the side edges of the column members forming the fallen end frame are caught in the grooves, so the column members forming the end frame when folded. can be stably maintained.

In addition, in the case of a two-story building, a connecting member is inserted into the screw holes provided on the lower surface of both ends of both girder members forming the floor frame, and on the upper surface of both ends of the front and rear finger members forming the roof frame. Therefore, when making the prefabricated building into a two-story structure, the connection members provided at both ends of the front and rear girder members forming the roof frame of the - floor, and the connecting members provided at both ends of the girder members of the floor frame of the second floor. Connecting members provided at both ends of the girder members of the second floor frame are brought into contact with each other, and fasteners such as bolts are inserted into holes drilled in the connecting members provided at both ends of the girder members of the second floor frame. A two-story building is easily assembled by connecting the roof frame on the - floor and the floor frame on the second floor by screwing into the screw holes provided in both ends of the girder member and the connecting members provided at both ends. It has many features such as being able to
