Abstract

PURPOSE:To connect cross beams of adjacent buildings to each other so as to integrally work. CONSTITUTION:Two connecting plates 30 are provided at a space on a floor beam 11 and a roof beam 20, respectively. The connecting plates 30 are welded between the edges of upper and lower flanges in such a manner as to cover the grooves of the beams 11, 20 by a steel plate where a bolt hole is bored. Both ends of the connecting plate 30 are bent inward, and the peripheral edges thereof are welded on the beams 11, 20. A working hole 31 is bored in the upper flange to put one's hand into the back of the connecting plate 30.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building which can be easily assembled and disassembled, and can be widely used in small and medium-sized offices, shops, suburban restaurants, and the like.

[0002]

2. Description of the Related Art In this type of building, in order to take up a large floor area, several buildings are connected (a series) or piled up to form a two-story building. In the case of a conventional prefabricated building, when connecting the buildings, the buildings are simply connected at both ends. For this reason, since the girders of the adjacent buildings do not work together, the girder deflection becomes excessive when a large load is applied from the second floor.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to connect girders of adjacent buildings so that they work together.

[0004]

In this prefabricated building, a connecting plate is provided in the middle portion of a girder having a U-shaped cross section with a groove facing outward. The connection plate connects the edges of the upper and lower flanges of the girder and is fixed between them. When connecting to multiple buildings, the connecting plates of two adjacent buildings are tightened with bolts inserted through them.

When both sides of the connecting plate are bent inward and the peripheral edges thereof are welded to the girder, the strength is increased. In this case, it is advisable to make a working hole in the upper flange of the girder so that the back side of the connection plate can be reached.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIG.
A floor panel 2, a roof panel 3, and a pillar 5 which are made in advance at a factory are carried to the site and assembled, and finally a wall panel 9 is attached. Each pillar 5 is a steel box shape,
Two columns having the same end face are connected to each other by beams 6 and 7 on the upper and lower sides.

The floor panel 2 has a groove 10 as shown in FIG.
The steel girders 11 having a U-shaped cross section pass through on both sides with the cross girders (not shown) in between, and the floor board 12
It is stretched. At the time of assembling, the lower part of the column 5 is placed on the end face of the floor girder 11 and tightened with two bolts 13 (FIG. 4). In order to enable the bolt tightening, an opening 15 is provided at the lower end of the column 5 toward the outside.

A bracket 16 projects from the column 5, and the web 11c of the floor girder and the eyepiece 17 welded on the girder 11 are fastened with three bolts 19.

The roof panel 3, as shown in FIG.
A steel girder 20 having a U-shaped cross section with 0 facing outward is passed through on both sides, a transverse girder (not shown) is passed between the girders, and a roof plate 21 is stretched.

A tenon 22 is formed on the pillar 5.
The tenon 22 is made of welded steel plate and is open on the outside. Mortise 2
One side of 2 is tapered, and when viewed from the side, it becomes thicker toward the bottom.

The roof girder 20 incorporates a socket 23 with which the tenon 22 is engaged. The socket 22 is composed of two vertically extending plates 23a and 23b, and a space having the same shape as the tenon 22 is formed between these plates. When assembling, the tenon 22 of the support 5 is fitted into the socket 23, and the plates 23a and 23b and the tenon 22 are fixed to the bolts 25 and 2.
Tighten with 6 (Fig. 4).

Since the tenon is fitted in the socket and bolted in this way, the connection between the roof girder 20 and the support column 5 becomes close to a rigid joint. Since the tenon 22 is tapered as described above, it is easy to fit it in the socket 23.

This prefabricated building may be used as one building having a large floor area by connecting several buildings as shown by a chain line in FIG. The floor girders 11 and the roof girders 20 are provided with two connecting plates 30 for this purpose at intervals.

The connecting plate 30, as shown in FIGS. 2 and 3,
It is a steel plate with bolt holes and is welded between the edges of the upper and lower flanges so as to close the groove 10 of the girders 11 and 20. Connection plate 3
Both ends of 0 are bent inward, and the periphery is 1
Weld to 1 and 20. Work holes 31 are formed in the upper flanges 11a and 20a so that the back side of the connection plate 30 can be accessed.

As shown in FIG. 1, when the two buildings are right next to each other as shown in FIG. 1, the connecting plates 30 of the respective buildings overlap each other. As shown in FIG. .

In this way, since the girders of adjacent buildings are integrally connected to each other, even in the case of a two-story building, it is possible to suppress the girder distortion caused by the load.
In addition, not only do they connect with the connecting plate 30 when they are connected, but also the roof girder 2
The end plate 33 of 0 and the lower side plate 35 of the support column are also connected to each other by bolts.

[0017]

According to the prefabricated building according to the first aspect of the present invention, the connecting plate is fixed to the middle portion of the girder by connecting the upper flange and the lower flange of the girder with a U-shaped cross section with the groove facing outward and adjoining them. To do 2
The connection plates of one building are tightened with bolts that are inserted through them, and when connecting them, adjacent girders are integrally connected and high strength is obtained. Also, the bolt fits in the groove of the girder and looks good.

According to a second aspect of the present invention, since both sides of the connecting plate are bent inward and the peripheral edges thereof are welded to the girder, the rigidity of the connecting plate can be increased, and moreover, the back side of the connecting plate can be touched. Since work holes are drilled in the upper flange of the girder, bolting work can be done easily.
