Description

[Detailed description of the invention] The present invention includes each of the supporting legs 3 of the precast reinforced concrete support plate A, in which the supporting legs 3 are suspended from the four corners of the rectangular horizontal main plate 2 with the notch step 1 cut out along the outer periphery. Mounted on foundation B, front, rear, left and right wall plates 4
Each wall plate 4a, 4b, 4c in a precast reinforced concrete shed C, which is formed by integrally connecting a roof plate 5 to the top of a rectangular cylindrical structure formed by integrally connecting a, 4b, 4c, 4d, 4d to the support plate A
Waterproof mortar 11 is placed on the notch step 1 between the horizontal main slab 2 and the bolts 6 inserted through the respective wall slabs 4a, 4b, 4c, 4d are inserted into the horizontal main slab 2. An assembly structure characterized in that it is screwed into a nut 8 which is fixed in the main plate 2 and has a tubular body 9 connected to its rear end, and the tip of the bolt 6 is inserted into the tubular body 9. The purpose of this is to provide an assembled building that is easy to assemble and disassemble and is structurally rational.

Note that the foundation B is made of, for example, a split chestnut constructed at the bottom of a foundation hole excavated underground. Further, the bolts 6 are connected to each wall plate 4 as shown in FIG.
a, 4b, 4c, and 4d are screwed into nuts 8 fixed to the horizontal main plate 2 by passing through the through holes 7 drilled in the wall plates from the recesses 4' provided on the lower outer circumferential surface of the plates. It's becoming like that. In the figure, reference numeral 10 indicates an anchor reinforcing bar welded to the tubular body 9, and reference numeral 12 indicates a washer embedded in the wall slab through which the bolt 6 is passed.

In addition, in the figure, 13 is a drain hole in the horizontal main plate 2, 14 is an opening provided in the wall plates 4b, 4c, and 4d, and 15 is an opening/closing door 16 provided in the wall plate 4a, which is bored in the wall plate 4d. vents.

As mentioned above, the prefabricated building according to the present project consists of a precast reinforced concrete support plate A with support legs 3 suspended from the four corners of the horizontal main plate 2 with cutout steps 1 along the outer periphery, and Wall plate 4a, 4
It is composed of a precast reinforced concrete shed C formed by integrally connecting roof plates 5 to the top of a rectangular cylindrical structure formed by integrally connecting blocks b, 4c, and 4d,
By transporting both to the required construction site and mounting the supporting legs 3 of the support plate A on the foundation B, the support plate A is set in a predetermined position, and the shed C is placed on the support plate A. 4 on each of the front, left, and right walls of the same shed C.
a, 4b, 4c, and 4d are mounted on the notch step 1 provided at the outer peripheral edge of the horizontal main plate 2 in the support plate A, and each of the wall plates is placed on the fixed nut 8 of the horizontal main plate 2. Since they are connected by screwing the bolts 6 that pass through them, the building can be easily assembled. In addition, since the wall slabs 4a, 4b, 4c, and 4d are mounted on the cutout step 1 and connected to the horizontal main slab 2 with bolts 6, the shed C can be accurately positioned. At this time, the tip of the bolt 6 is inserted into the tube 9 connected to the rear of the nut 8, so that the bolt is long and the bolt body is protected by the tube 9, preventing dirt and contamination. , which prevents distortion and can be easily removed during disassembly. Further, the horizontal displacement of the shed C is prevented by the cutout step portion 1, and the shed C is prevented from being displaced in the horizontal direction.
is firmly connected to the support plate A.

Furthermore, the horizontal main plate 2 and each wall plate 4a, 4b, 4
Since the waterproof mortar 11 is interposed between the parts c and 4d, an assembled building with excellent waterproof performance is constructed.

In addition, the shed C has wall plates 4a, 4b on the front, rear, left and right sides,
4c, 4d and the roof slab 5 are integrally constructed, the joints of each structural member of the shed C are constructed to be strong and strong, which is structurally advantageous, and has excellent water resistance, fire resistance and heat resistance, and is easy to maintain. Advantageous for management. Note that the position of the window frame and the gap can be freely selected for each of the above-mentioned wall slabs.

Further, the support slab A constitutes the foundation of the shed C, and the horizontal main slab 2 also serves as a floor slab, eliminating the need for pouring concrete for the dirt floor. In addition, by molding the support plate A by reverse pouring of fresh concrete when manufacturing the support plate A, the surface can be finished densely and surface finishing can be made unnecessary.

This proposal applies to small buildings such as bus shelters, storerooms, study rooms, simple toilets, garbage collection sheds, school sports club rooms, baths, greenhouses, various administrative offices, and hazardous materials storage sheds. It is.
