For example, Japanese Patent Application Laid-Open No. 185856/1983 discloses a structure in which a hanging scaffold is attached to hanging bolts that are arranged to hang below a steel frame. According to this suspended scaffolding, the hanging bolts, which are fixed in advance to the H steel beams by welding or the like, and the hanging structure fixed to the suspended scaffolding are connected by screwing. It was hot. Therefore, the fixed position of the suspended scaffold suspended from the suspension bolt is determined by the position of the suspension bolt fixed to the beam material,
In order to adjust the mounting position of a suspended scaffold, the hanging structure fixed to the suspended scaffold must be disassembled once, in order to accurately adjust the mounting position of the suspended structure itself, which is extremely inconvenient during installation work. It was hot. Furthermore, although this suspended scaffold can be used both as a working scaffold and a support for beam construction, it has the disadvantage that it cannot be used for ceiling construction after beam construction. According to this scaffold, a tube supporting the handrail is erected upward from both ends of a support tube on which the scaffold body is placed, which is horizontally supported under the steel frame, and a slidable inner tube is inserted into the tube. Therefore, it can be used as a scaffold for constructing beams, but it cannot be used when constructing a ceiling because the handrail and the pipe supporting the handrail interfere with ceiling construction. Therefore, when constructing the ceiling, it was necessary to dismantle the suspension scaffolding for the beam construction and install another scaffolding for the ceiling construction, which not only delayed the construction period but also required a large amount of temporary equipment.

The purpose of this project is to provide a suspended scaffold that can also be used as a suspended formwork to shorten the construction period and reduce the need for temporary construction equipment.

図ることも可能になるものである。 That is, a pair of hanging bolts 3 are suspended from a steel frame 1 for constructing a beam of a steel reinforced concrete structure, and a large underwriting washer 6 is provided on top of the hanging bolt 3 on which a large tension material 11 for constructing the formwork is placed. Horizontal pipe 1 with handrail receiving pipes 14 slidably installed at both ends
7 is suspended from the hanging bolts 3, and a continuous uneven fitting surface 2A is provided along the longitudinal side of the scaffold. The suspension body 2 to be suspended and a continuous uneven engagement surface 9A are provided along the longitudinal side, and are connected to the horizontal pipe 17 via a predetermined connecting member 10 connected to the horizontal pipe 17.
The fitting surface 2A of the suspension body 2 is fixed in parallel above the
A locking rod 9 is fitted and locked orthogonally to the locking rod 9, and a pressing rod 8 is detachably fixed to the locking rod 9 to press the hanging body 2 against the locking rod 9. As a result, the work of suspending the horizontal pipe 17 can be carried out much more easily. Moreover, since the fitting surface 2A of the suspension body 2 and the engagement surface 9A of the locking rod 9 each form a continuous uneven shape, the positions of the fitting and locking surfaces can be freely changed vertically and horizontally. This makes it possible to adjust the installation position of the horizontal pipe 17 very easily and over a wide range. Furthermore, since the handrail receiving pipes 14 that are slidably erected from both ends of the horizontal pipe 17 can be freely slid vertically downward, the handrail receiving pipes 14 can be erected up to the height around the beam, and the SRC structural beam It is used as a suspended scaffold for assembling reinforcing bars and formwork, etc., and after the large tension material 11 for formwork construction is placed on the large support washer 6 and used as a suspended formwork for a beam, it is used as a handrail. Receiving pipe 1
By sliding 4 to an appropriate position below the beam, it can be used as a scaffold for constructing ceiling panels and the like. Therefore, by adjusting the height of the handrail receiving pipe 14, it becomes possible to erect the scaffold board A at the optimal position as a scaffold for ceiling construction. Therefore, it is possible to use the same suspended scaffolding from installation of the steel frame 1 of the SRC structural beam and assembling the reinforcing bars, to construction of the beam formwork, and even ceiling construction, thereby shortening the construction period. Not only will it be possible to do this, but it will also be possible to rationalize temporary equipment.

A pair of hanging bolts is suspended from a steel frame for constructing a beam of a steel-framed reinforced concrete structure, and a large underwriting washer is placed on top of the hanging bolt for placing a large tension material for formwork construction. In a suspended scaffold that also serves as a suspended formwork, a horizontal pipe with handrail receiving pipes slidably erected at both ends is suspended from hanging bolts.
A continuous uneven engagement surface is provided along the longitudinal side, a suspension body extends downward from the lower end of the suspension bolt to suspend the scaffold, and a continuous uneven engagement surface is provided along the longitudinal side. A locking rod is provided along the horizontal pipe and is fixed in parallel above the horizontal pipe via a predetermined connecting member connected to the horizontal pipe to fit and lock orthogonally to the fitting surface of the suspension body; A suspended scaffold that doubles as a hanging form frame is provided with a pressing rod that is detachably fixed to the anchoring rod and presses the hanging body against the anchoring rod. 2. The fitting surface has a convex portion fitted into a concave portion of the fitting surface itself, and a convex portion of the fitting surface itself is locked to a side edge of the concave portion of the fitting surface. A suspended scaffold that also serves as a suspended formwork as described in item 1. 3 A pair of fitting surfaces are formed along the open end of the suspension body having a substantially U-shaped cross section;
A hanging scaffold that can also be used as a hanging formwork as claimed in claim 1 or 2, wherein an appropriate number of pairs of anchoring rods having a substantially U-shaped cross section are formed at the open end.
