FIG. 1 shows a temporary scaffold 6 and a temporary scaffold 8 for a shed provided at a construction site 4 of a house 2. After the temporary scaffold 6 has the jack base 9 and the support 10 arranged at a predetermined interval of 1800 mm around the house 2, the support 10 is connected by a horizontal horizontal connection 12, and the tread 14 is installed at a desired position via a bracket. And a brace (not shown). The horizontal connecting member 12 connects the columns 10 by inserting wedge-shaped engaging portions provided at both ends thereof into box-shaped connecting portions 16 provided at predetermined intervals in the vertical direction of the columns 10. The box-shaped connecting portion 16 is
Four positions are provided at equal intervals around the column 10, and the mounting positions of the opposing box-shaped connecting portions 16 are at the same height, and the mounting positions of the adjacent box-shaped connecting portions 16 are the height of the box-shaped connecting portion 16. It is shifted upward or downward by an amount (see FIG. 2).

[0009] The temporary scaffolding 8 for the shed is used to construct the wall 18 on the second floor of the main building at a position recessed from the shed 22.
Is provided in the vicinity of. The columns 20, 20 located at both ends of the temporary shed for scaffolding 8 are attached to the beams 1, 1 for the shed arranged with the shed 22 therebetween. The pillars 1 for the shed 1 and the pillars 10 a and 10 b and the pillar 1 arranged on the side of the shed 22 in the pillar 10 constituting the temporary scaffold 6.
At 0c and 10d, respectively. A plurality of columns 24 are provided on the roof of the shed 22 between the columns 20, 20.
Are, for example, arranged at 900 mm intervals,
The tread plate 14 is attached to 24 via a bracket.

As shown in FIGS. 2 and 3, the beam 1 for a shed is attached to a beam main body 26 having the same form as the horizontal connecting member 12, and column connecting portions (column connecting means) 28 and 30 are reinforced at a lower portion. The plate 32 is formed by welding. In addition, beam body 2
6, wedge-shaped engaging portions 34, 34 (fixing means) bent substantially in an L-shape are formed at both ends. The strut connecting portion 28 connects the wedge-shaped engaging portions 34, 34 with the struts 10a, 10a.
In the state of being inserted and fixed in the box-shaped connecting portions 16 and 16 of b,
It is mounted so as to be located at the center of the beam main body 26 in the longitudinal direction (at a position separated by 900 mm from the center of the column 10b), and similarly, the other column connecting portion 30 is mounted at a position separated by 300mm from the center of the column 10a. is there.

The mounting positions of the column connecting portions 28 and 30 are not limited to the above-mentioned positions, but may be used by mounting them at desired positions.

The column connecting portions 28 and 30 are each formed of a column having a diameter corresponding to the inner diameter of the column 20 so that the column 20 formed of a pipe is fitted to the outside. In addition, pin holes 29 and 31 corresponding to the pin holes 21 of the support 20 are formed in the support connecting portions 28 and 30, respectively. For example,
After connecting the strut 20 to the strut connecting portion 28, a connecting pin is inserted into the pin holes 21 and 29, so that the strut 20 is
8 is prevented. Also, as mentioned above,
Since the box-shaped connecting portion 16 provided on the column 10 has a displacement corresponding to the height of the box-shaped connecting portion 16 at the mounting position of the adjacent ones, it differs when the beam 1 for the shed is arranged in the orthogonal direction. A displacement in the height direction occurs between the column connecting portions 28 and 30 of the shed beam 1. In order to eliminate this displacement, collars 36, 38 having the same height as the box-shaped connecting portion 16 are detachably attached to the column connecting portions 28, 30. The collars 36 and 38 are connected to the beam main body 2 by chains 40 and 42.

May have multiple openings for weight reduction,
The reinforcing plate 32 itself may be changed to a lattice structure.

The beam main body 26 of the beam 1 for a shed may have a cylindrical or prismatic shape, and the fixing means may be a clamp or a screw instead of the wedge-shaped engaging portions 34, 34. In addition, the column connecting members 28 and 30 are not limited to the above configuration, and may be configured by a clamp to connect the column 20, or the mounting position thereof can be detachably attached to the beam main body 26 by screwing. May be provided.

As shown in FIG. 2, the strut 20 is connected to an arbitrary one of the strut connecting portions 28 and 30.
If the strut 20 is connected to both of the strut connection portions 28 and 30, the temporary scaffolding 8 for the shed can be increased. In addition, either one of the column connecting portions 28 and 30 attached to the shed beam 1 may be provided, or the number of columns may be increased as necessary.

[0016]

As is clear from the above description, the shed beam according to the present invention is fixed between the columns of the temporary scaffold, and is used by connecting the columns constituting the temporary scaffold for the shed. . Therefore, since it is not necessary to provide the pillar of the temporary scaffold for the shed between the pillars of the temporary scaffold, the work of allocating the pillar of the temporary scaffold can be easily performed. In addition, since long and heavy struts, which were conventionally used at both ends of the temporary scaffold for shed, are not used,
The work of assembling the temporary scaffold and the temporary scaffold for a shed becomes easy. Furthermore, since the installation, movement, and extension of the pillars that constitute the temporary shed for scaffolding can be performed by installing, moving, and increasing the beams for shed, it can be easily performed without reassembling the temporary scaffold. In addition, the use of the beam for the shed makes the temporary scaffold and the temporary scaffold for the shed excellent in appearance.

If the column connecting means is detachably provided at a desired position in the longitudinal direction of the beam, the column constituting the temporary scaffold for the shed can be freely moved within the longitudinal interval of the beam for the shed. Therefore, the installation position of the temporary shed for scaffolding can be changed within the longitudinal interval of the beam for shed.
