BRIEF DESCRIPTION OF THE DRAWINGS It is a perspective view which shows one Example of the frame member for hanging scaffolds of this invention. It is a perspective view showing the disassembled state of one embodiment of the frame member for hanging scaffolds of the present invention. It is a perspective view showing one example of a hanging scaffold using a frame member for hanging scaffolds of the present invention. It is a perspective view showing one example of a hanging scaffold using a frame member for hanging scaffolds of the present invention. It is a figure which shows the front-end surface of the front-end frame in the frame member for hanging scaffolds of this invention.

Hereinafter, a frame member for a hanging scaffold according to the present invention will be described in detail with reference to the drawings.

The frame member for a suspended scaffold according to the present invention is formed by combining various frames as shown in the figure, and has a rectangular shape as a whole. The basic configuration thereof includes a front end frame 1 on one long side and a pipe on the other long side. It comprises a frame 2, two side frames 3 provided at both ends of both long side portions, and a plurality of joist frames 4 provided between both long side portions.

As shown in Fig. 2, the frame member used at the start or when cutting the edge at a curve, etc., needs to be suspended at four points. The structural configuration (Claim 2) includes two end frames 1 forming both long side portions, two side frames 3 provided at both ends of both long side portions, and a span between both long side portions. And a plurality of joist frames 4.

In the embodiment of FIGS. 1 and 2, a unit (4 m unit) for laying three 4 m scaffold treads is used. However, the size of a frame member such as a unit (3 m unit) for laying three 3 m scaffold treads is It is set appropriately.

As described above, the frame member for a suspended scaffold according to the present invention connects the frame members to form a scaffold of a predetermined range according to the work site, and constructs a floor surface by laying a scaffolding tread X on each frame member. The embodiment shown in FIG. 4 is one embodiment of the entire suspension scaffold using the present invention.

In this embodiment, a suspended scaffold constructed with a total scaffold width of 10 m (longitudinal direction in a rectangular frame member) using each frame member of 4 m unit, 3 m unit and 4 m unit is constructed.

In the embodiment, the end frame 1 is made of a long extruded aluminum material having a constant cross-sectional shape in the longitudinal direction, and is, for example, a substantially rectangular cylindrical body provided with a vertically elongated rectangular hole in a sectional view.

  On the upper surface of the end frame 1, a T-groove 1A having a wide portion through which a nut can be inserted is provided continuously from the opening ridge portion to the bottom along the longitudinal direction.

As described above, the suspended scaffold frame members are formed by connecting the respective frame members to form a scaffold as needed. Therefore, the use mode of the T-groove 1A is not limited to a single frame, but may be a plurality of frames. It can be realized even in between.

Therefore, the hanging scaffold frame member according to the present invention has a structure in which the T-groove is continuously provided in the constituent frame, and by using a T bottle, the degree of freedom of the hanging portion of the hanging scaffold on the single frame can be improved. Dramatically increased, and between the multiple frames, it is possible to freely arrange various accessories such as bogie traveling rails across each frame member and connecting pipes for edge curing, according to the situation at the site Become.
That is, as shown in FIG. 4, a plurality of hanging chains S are attached to arbitrary locations along the longitudinal direction of a single end frame via a T-groove 1A, and a plurality of end frames (width direction). , A bogie traveling rail R is attached at an arbitrary position.

The end frame 1 is provided with a single tube clamp 1C for fixing the pipe frame 2 forming the other long side in order to connect the frame members continuously.

In addition, a groove surface 1B having a constant width is continuously formed along the longitudinal direction on the side surface of the distal end frame in order to cope with coupling of various members.

In the embodiment, the pipe frame 2 has a cylindrical shape provided with a circular hole in a sectional view.

  The side frames 3 are provided at both ends of the end frame 1 and the pipe frame 2 (in the second embodiment, both end frames 1), and form short sides of the frame member.

The connection between the side frame 3 and both long side portions is appropriately performed by a known connection method such as through a bolt and a nut. The connection portion with the end frame 1 is a cylinder for connecting another frame member. It is assumed that the cylindrical member 3A into which the joint piece J can be inserted protrudes.
The joint piece J has a cylindrical shape, and is configured to be insertable from either the left or the right.

  The joist frame 4 is installed in parallel with the side frame 3 between the end frame 1 and the pipe frame 2 (in the second embodiment, between the end frames 1).

The connection between the joist frame 4 and both long side portions is appropriately performed by a known connection method such as via a bolt and a nut. However, the connection portion with the pipe frame 2 is slidably mounted on the cylindrical pipe frame so as to be slidable. It is assumed that a cylindrical member 4A that allows the user to easily select is provided.

Further, in the joint portion of the frame member with the front end frame, the erection position can be easily selected by being slidable with respect to the width of the groove surface 1B formed on the side surface of the front end frame. It is assumed that a flat member 4B is disposed.

In the frame member for a suspended scaffold according to the present invention, the degree of freedom of the erection point is increased by making the joist frame a separable component.

  As described above, the free joist frame is erected at an appropriate place, and the scaffold treads X of various lengths to be laid on the frame member are combined to form the opening H at an arbitrary position on the scaffold floor as shown in FIG. It can be provided. In the illustrated embodiment, an opening with a long side of 1 m can be provided by laying one 4 m scaffold tread and two 3 m scaffold treads on a frame member of 4 m unit.

By the combination of the frame members, an opening can be provided at an arbitrary position on the entire construction scaffold, and as shown in FIG. 4, it is possible to cope with an obstacle Y in the construction scaffold.

  In the frame member according to the present invention, the distal end frame 1, the pipe frame 2, the side frame 3, and the joist frame 4 are each configured as an independent member, and these frames are connected using a connecting member such as a joint piece J. . Therefore, it is possible to deal with breakage or the like of a part by replacing or repairing the corresponding frame, and it is possible to provide a frame member for a hanging scaffold that contributes economically.
