Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffold that is used by being bridged between structures of a building when performing roof construction, finishing work on an inclined ceiling, and the like.

[0002]

2. Description of the Related Art A scaffold plate described in, for example, Japanese Utility Model Publication No. 3-16992 is known as a scaffold that can be used for roof construction and slope ceiling finishing work.

This scaffold plate is composed of a pair of vertical members and a pair of horizontal members, several reinforcing members provided between the vertical members, and expanded metal. , A U-shaped locking member is fixed, and by locking the locking member to a pipe or the like, it is possible to bridge between the parallelly arranged structures.

[0004]

However, in such a conventional scaffold plate, the scaffold plate can only be erected between structures arranged at intervals between the locking members of the scaffold plate. Therefore, if the scaffold is lengthened in order to expand the applicable range, the strength of the scaffold will be insufficient. In order to supplement the strength of the scaffold plate, it is conceivable to increase the number of reinforcing members. However, in this case, the weight of the scaffold plate increases, and there is a problem that it is inconvenient to carry.

In view of the above, the present invention has been made in view of the above problems, and has an object to provide a scaffold having sufficient strength even between structures arranged at wide intervals. It is an object.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, a pair of assembly beams fixed in a state of being bridged between structures of a building, and a pair of assembly beams between the assembly beams And a scaffold plate supported in a bridging state. In the invention described in claim 2, in the invention described in claim 1, a plurality of the scaffold plates can be juxtaposed in the longitudinal direction of the assembly beam. According to a third aspect of the present invention, in the third aspect of the invention, in the third aspect, the scaffold plate and the assembly beam can be disassembled. In the invention, in the invention according to claim 1 or 2, the assembly beam is configured to be foldable with respect to the scaffold plate. The assembled beam is a beam made by combining several single members, and includes a truss beam, a lattice beam, a ladder beam, and the like.

[0007]

According to the first aspect of the present invention, the assembly beams are bridged between the structures of the building, and the scaffolding plate is bridged between the assembly beams, so that the structures arranged at wide intervals are arranged between the structures. Thus, a scaffold having sufficient strength can be formed. According to the second aspect of the present invention, since the plurality of scaffolding plates are formed in such a size that they can be juxtaposed in the longitudinal direction of the assembly beam, the scaffolding plates can be reduced in size and weight. According to the third aspect of the present invention, storage and transportation can be performed in a state where the scaffold plate and the assembly beam are disassembled. According to the fourth aspect of the present invention, the assembly beam can be stored and transported in a state where the assembly beam is folded with respect to the scaffold plate.

DESCRIPTION OF THE PREFERRED EMBODIMENTS First, based on FIGS.
The scaffold according to the first embodiment will be described in detail. FIG. 1 is a perspective view showing a scaffold of Embodiment 1, FIG. 2 is a perspective view showing an assembly beam of the scaffold of Embodiment 1, FIG. 3 is an enlarged view of a main part III of FIG.
FIG. 4 is a perspective view showing a scaffold plate of the scaffold according to the first embodiment, in which 1 is a building unit and 2 is a scaffold.

The building unit 1 has a rectangular floor 11
And a pair of walls 1 erected on two short sides of the floor 11.
2 and 12.

The scaffold 2 is provided on the wall 12 of the building unit 1,
A pair of truss beams 21 fixed in a state of being bridged between 12
And a plurality of scaffolding plates 22 supported between the truss beams 21 in a bridging state.

The truss beam 21 includes an upper chord member 211 and a lower chord member 212 and a plurality of diagonal members 2 provided between them.
13, a fixing plate 2 for fixing to the wall 12 of the building unit 1 is provided at both ends of the upper chord material 211.
14 are provided. Note that a metal pipe is used for the upper chord member 211, the lower chord member 212, and the diagonal member 213, and the fixing plate 214 is used for the lower chord member 21.
2 is welded.

The scaffolding plate 22 is formed by forming a frame with a pair of vertical members 221 and a pair of horizontal members 222, and expanding metal 223 is fixed to one surface of the frame.
U-shaped locking portions 224 that can be locked to the lower chord material 212 of the truss beam 21 are provided at both ends of the truss beam 21. In addition, this scaffolding plate 22 is such that
The length is shorter than one, and a plurality of scaffolding plates 22 can be juxtaposed in the longitudinal direction of the truss beam 21. That is, it is formed in a size and a weight that are easy to carry.

That is, the scaffold 2 can be disassembled into a truss beam 21 and a scaffold 22, and can be stored and transported in a disassembled state. Also, at the construction site, after the pair of truss beams 21 and 21 are hung over the walls 12 and 12 of the building unit 1 and fixed, the scaffold plate 22 is placed at an appropriate position according to the work.
All that is required is to bridge and support it. in this way,
Since a pair of truss beams 21 and 21 are bridged between the walls 12 and 12 and the scaffold plate 22 is bridged between the truss beams 21 and 21 for assembly, it is assumed that the walls 12 and 12 are arranged at wide intervals. However, sufficient strength can be ensured.

Next, the configuration of the scaffold according to the second embodiment will be described with reference to FIG. FIG. 5 is a perspective view showing a scaffold according to the second embodiment. In this scaffold, a lower chord 212 of a truss beam 21 is fixed to an upper end of a wall 12 of the building unit 1. That is, the fixing plates 214 for fixing to the wall 12 of the building unit 1 are provided at both ends of the lower chord material 212. That is, the truss beam 21 functions as a handrail when working on the scaffolding plate 22, and contributes to improving safety during the work. The other configuration and operation are the same as those in the first embodiment, and a description thereof will not be repeated.

Although the preferred embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this preferred embodiment, and a design change or the like may be made without departing from the scope of the present invention. Even if present, it is included in the present invention. For example,
In the embodiment, the scaffold which can be disassembled into the scaffold plate and the assembling beam is shown, but the assembling beam may be formed so as to be foldable with respect to the scaffold plate. Further, in the embodiment, the example in which each member of the assembly beam is a metal pipe has been described, but an angle material having an L-shaped cross section may be used instead of the metal pipe. Further, in the embodiment, the example in which the scaffold is assembled by bridging the assembly beam between the pair of walls has been described. You may.

[0016]

As described above, according to the first aspect of the present invention, an assembling beam can be bridged between structures of a building, and a scaffold plate can be bridged between the assembly beams. Therefore, an effect is obtained that a scaffold having sufficient strength can be installed even between structures arranged at wide intervals. In the invention according to claim 2,
Since the size and weight of the scaffold plate can be reduced, the effect of easily carrying the scaffold plate can be obtained. According to the third aspect of the present invention, since it can be disassembled into the scaffold plate and the assembling beam, there is obtained an effect that space efficiency during storage and transportation is good. According to the fourth aspect of the present invention, since the assembling beam can be folded with respect to the scaffold plate, an effect that the space efficiency at the time of storage and transportation is good is obtained.
