Description

  The present invention relates to a suspended scaffold.

In the conventional suspended scaffold, a load support material is attached to the vertical frame of the scaffold unit, and the load of the scaffold is supported by the building frame. (For example, see Patent Document 1)
Conventionally, there is a structure in which an engagement / disengagement means is provided on a frame of a suspended scaffold and is attached to an overhanging portion of a veranda which is a building frame to support the load of the scaffold. (For example, see Patent Document 2)

  However, since the suspension scaffolds of Patent Documents 1 and 2 described above could not attach the load support material or the engagement / disengagement means to any position of the building frame, it was difficult to install the scaffolding depending on the shape of the building. there were. (Refer to FIG. 3B and FIG. 4B) For this reason, it was necessary to separately manufacture a scaffolding adapted to the outer shape of the building frame, and the cost could not be reduced.

  In addition, when replacing the conventional suspension scaffold, the fixing work after the scaffold replacement cannot be easily performed, and thus there is a high risk of damaging the building frame. In addition, since the number of load supporting members and engaging / disengaging means per unit was large, it took time for refilling work.

Furthermore, as shown in FIG. 6B, the conventional scaffold has a low height between the upper and lower scaffolding plates (about 1,700 mm) and must be operated while bending the waist, which is efficient. I couldn't work.

  The problem to be solved by the present invention can be freely laid out without being influenced by the outer shape of the building frame, can be refilled quickly and easily, and improves the workability inside the scaffolding It is to provide a suspension scaffold that can be used.

  The suspended scaffold of the present invention includes a scaffold unit composed of a vertical frame, a scaffold plate, a brace, etc., a plurality of vertical frames that are closer to the building frame of the scaffold unit, and a plurality of vertical frames that are far from the building frame. It is composed of a horizontal connecting member that is attached to each side horizontally and at the same height, a bracket that supports these horizontal connecting members at arbitrary positions, and a bracket receiving member that is detachably attached and fixed to the bracket. Features. Further, the bracket is attached to a horizontal connecting member by a pivot pin so as to be rotatable. Further, the height between the upper and lower scaffolding plates is set to about 1,900 mm.

1) A scaffold layout with a high degree of freedom can be obtained without being influenced by the outer shape of the building frame.
2) The scaffold replacement work can be performed quickly and easily.
3) Since the height between the upper and lower scaffolding plates is set higher than before, the workability inside the scaffolding can be improved.

  FIG. 1 shows an embodiment of a suspended scaffold according to the present invention, wherein 1 is a scaffold unit, 2 is a building frame, and 3 is a wall joint. The scaffold unit 1 includes a plurality of scaffold frames 1a composed of a vertical frame 1a-1 and a lateral frame 1a-2, a scaffold plate 1b that is fixedly secured to the lateral frame 1a-2 of the left and right scaffold frames 1a, The brace 1c is connected to the vertical frame 1a-1 of the scaffold frame 1a. The scaffold unit 1 of the present invention is not limited to the above-described structure, and may be any conventionally known framework scaffold. The scaffold unit 1 is composed of a plurality of layers and spans, and is fixed to the building frame 2 by the wall joint material 3.

Reference numeral 4 denotes a horizontal connecting material, which is fixedly attached to a side portion at an arbitrary height position of the vertical frame 1a-1 of the scaffold unit 1 as a set. In other words, the horizontal connecting members 4 are attached to the sides of the vertical frame 1a-1 closer to the building housing 2 (inner side) and the vertical frame 1a-1 closer to the outer side (outer side) at the same height. It has been. When there are many layers of the scaffold unit 1, a plurality of horizontal connecting members 4 may be attached and arranged.

  A bracket material 5 supports the vertical load of the scaffold unit 1. As apparent from FIG. 2, the outer end portion 5 a is rotatably attached to the outer horizontal connecting member 4 by a pivot pin 6. The bracket material 5 is allocated and attached to a desired position of the horizontal connecting material 4. The inner end portion 5b of the bracket member 5 extends inward of the scaffold unit 1 (building housing 2 side), and is detachably attached to the bracket receiving member 7.

  In order to attach the bracket member 5 to the bracket receiving member 7, the scaffold unit 1 to which the bracket member 5 is attached is brought close to the building frame 2 while being lifted by a crane (not shown) or the like, and is shown in FIG. As described above, the inner end portion 5 b of the bracket member 5 is placed on the first receiving pin 7 a of the bracket receiving member 7. In this state, when the inner end 5b of the bracket member 5 is further pushed in and the tip reaches the lower side of the second receiving pin 7b of the bracket receiving member 7, the scaffold unit 1 is lowered, and the fixing hole 5c of the bracket member 5 and the bracket receiving member 5 are received. The position of the fixing hole 7c of the material 7 is adjusted, and the fixing pin 8 is inserted and fixed as shown in FIG. 2 (B). When the bracket member 5 is removed from the bracket receiving member 7, the above procedure may be reversed.

  As described above, since the bracket member 5 of this embodiment can be assigned and attached to a desired position of the horizontal connecting member 4, the assigned position of the bracket member 5 is adjusted and moved as shown in FIG. By adjusting the position of the scaffold unit 1 in the direction of the arrow, the gap G1 between the scaffold units 1 can be eliminated and the corner G2 between the corners can be eliminated without being influenced by the external dimensions of the building housing 2. it can.

  Further, as shown in FIG. 4B, when the building housing 2 has protrusions such as a fence H, the positions of the bracket 5 and the bracket receiving material 7 are changed from the state of FIG. It can be moved easily.

  Further, as shown in FIG. 5, when the corner shape of the building frame 2 is deformed, an L-shaped horizontal connecting member 4 ′ is manufactured, and this is used as a ready-made frame member F or scaffolding plate P. It can be integrated and dealt with. R is a gap plate.

  As shown in FIG. 6 (A), the height of the upper and lower scaffolding plates 1b is 1,900 mm, which is higher than the conventional (B) 1,700 mm, so that the work can be performed in an easy posture without bending the waist. It is possible to improve work efficiency.
