Abstract

(57) [Summary] [Purpose] Even when suspending scaffolds are installed on both the left and right sides of the steel beam 1, the suspending scaffolds are provided only on one side surface of the steel beam 1 and the horizontal members 3 project on the other side surface. Even if it is not provided, one kind of suspension scaffolding frame can be used. [Structure] Horizontal members 3 are provided on the left and right sides of the lower end of a suspension member 2 whose upper end is fixed to a steel beam 1, and the horizontal members 3 on both the left and right sides are provided.
In the suspension scaffolding frame in which the handrail pillars 4 are respectively erected at the outer end portions of the above, one of the horizontal members 3 on both the left and right sides is formed slidably in the left and right direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a suspension scaffolding frame that is attached to a steel beam at a predetermined interval in order to support a footboard of the suspension scaffold when the suspension scaffold is installed along the steel beam at a construction site.

[0002]

[Prior Art]

 The suspension scaffolding frame is composed of a suspension member whose upper end is fixed to the steel beam, horizontal members provided on both left and right sides of the lower end of the suspension member, and handrail columns provided on the outer end of the horizontal member. To be done.

Then, the suspension scaffolding frame is attached to the steel frame beams at a predetermined interval so that the horizontal frame members are orthogonal to the steel frame beams, and the walking board is bridged between the horizontal frame members of the adjacent suspension frame frames. Therefore, the scaffold is provided along the steel beam.

[0004]

[Problems to be solved by the device]

 By the way, in the above-mentioned conventional suspension scaffolding frame, since horizontal members for bridging the walking boards are provided on both the left and right sides of the lower end of the suspension member fixed to the steel beam, it is possible to walk on both the left and right sides of the steel beam. Scaffolding can be provided by spanning boards.

However, in the case of a steel beam that is provided along the outer surface of a building, a temporary scaffold that surrounds the building is provided close to the outer surface of the steel beam, so the suspension scaffold is provided only on the inner surface side of the steel beam. Be done. For this reason, in the past, the suspension scaffolds used for steel beams located on the outer surface of the building were placed on the left and right sides so that the horizontal materials on the outer surface side of the suspension scaffolding frame do not interfere with the temporary scaffolds surrounding the building. Among the frame materials, the horizontal frame material on the outer surface side of the steel beam is cut.

[0006] Therefore, conventionally, there are two types of suspension scaffolding frames provided on the construction site with horizontal members on both left and right sides of the suspension members, and those provided with horizontal members on only one side of the suspension members. Since they are mixed, there is a problem that assembly or material management becomes complicated.

Therefore, in the present invention, even when suspending scaffolds are installed on both the left and right sides of the steel beam, the suspending scaffold is provided only on one side surface of the steel beam, and the horizontal member is prevented from protruding on the other side surface. In the case of doing so, it will also be possible to deal with it with one type of suspension scaffolding frame.

[0008]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides horizontal members on the left and right sides of the lower end of a suspension member whose upper end is fixed to a steel frame beam, and the handrail pillars are provided on the outer ends of the horizontal member on both the left and right sides. In the suspension scaffolding frame with the erected, one of the horizontal members on both the left and right sides was formed slidably in the left and right directions.

[0009]

[Action]

 For the suspension scaffolding frame with the above configuration, extend one horizontal member that is slidable in the left-right direction and use it so that the horizontal length from the hanging member is the same as the other horizontal member. This allows suspension scaffolds to be installed on both the left and right sides of the steel beam.

Further, when the suspension scaffold is installed only on one side of the steel beam, by contracting one of the slidably formed horizontal members, the horizontal member on the side where the suspension scaffold is not installed is outwardly moved. It doesn't get in the way because it doesn't stick out.

[0011]

【Example】

 An embodiment of this invention will be described below.

The suspension scaffolding frame of the present invention includes a suspension member 2 having an upper end fixed to a steel beam 1, horizontal members 3 provided on both left and right sides of the lower end of the suspension member 2, and an outer side of the horizontal member 3. It is constituted by a handrail post 4 provided at the end portion, and one of the left and right lateral members 3 is slidably formed in the left-right direction.

The horizontal member 3 includes a large-diameter pipe 5 made of steel, and a steel insertion pipe 6 slidably inserted into the large-diameter pipe 5, and the outside of the insertion pipe 6 An auxiliary pipe 7 made of steel and having the same diameter as the large diameter pipe 5 is connected to the end portion.

A butterfly bolt 8 for fixing the insertion pipe 6 inserted in the large-diameter pipe 5 is attached to an inner end portion of the large-diameter pipe 5, and a little outside of the butterfly bolt 8 is attached to the outside. A bolt 10 is attached which engages with a stopper 9 provided at the front end of the insertion tube 6 to prevent the insertion tube 6 from coming off.

The hanging member 2 is attached to a mounting plate 11 fixed to the lower surface of the steel beam 1 by welding, bolting, or the like, a steel bolt mounting plate 13 mounted by a bolt 12, and the bolt mounting plate 13. It is composed of two steel pipe members 14 fixed in an eight shape.

The handrail pillar 4 is formed of a steel pipe material, and a clamp 16 for attaching the single handrail pipe 15 is provided at the upper end, and a rope thread ring 17 is provided in the middle. Has been.

When installing the suspension scaffolds on both the left and right sides of the steel beam 1 using the suspension scaffolding frame configured as described above, pull out the insertion pipe 6 as shown in FIGS. 1 and 3. With the insertion tube 6 fixed with the screw bolts 8, the bolt mounting plate 13 at the upper end of the suspension member 2 is fixed to the mounting plate 11 on the lower surface of the steel beam 1 with the bolt 12. In this way, the suspension scaffolding frames are attached to the steel beam 1 at a predetermined interval, and the walking boards 18 are laid over the horizontal members 3 of the adjacent suspension scaffolding frames to suspend them on both sides of the steel beam 1, respectively. Scaffolding is installed.

When the suspension scaffold is installed only on one side of the steel beam 1, the insertion pipe 6 of the suspension scaffold frame is inserted into the large-diameter pipe 5, and the insertion pipe 6 is attached with the butterfly bolt 8. In the fixed state, the insertion pipe 6 side of the suspension scaffolding frame is set to the side where the suspension scaffolding is not installed and the suspension scaffolding frame is fixed to the steel beam 1, so that the horizontal member 3 on the side where the suspension scaffolding is not installed is removed. You can keep it from protruding.

[0019]

[Effect of the device]

 According to the present invention, as described above, even when suspending scaffolds are installed on both the left and right sides of the steel beam, the suspending scaffold is installed only on one side surface of the steel beam and the horizontal members are projected on the other side surface. If you do not want to do so, you can deal with one type of suspension scaffolding frame.
