Description

[Detailed Description of the Invention] The present invention relates to a scaffolding device used when constructing overhanging parts such as balconies of high-rise concrete structures.

Conventionally, scaffolding frames used when constructing overhanging parts such as balconies of high-rise concrete structures were either stacked from the ground around the outer periphery of the structure and erected over the entire surface, or After the poured concrete has hardened, it is fixed to the lower part of the structure or balcony concrete, which not only reduces work efficiency but also prevents unnecessary scaffolding from being piled up from the ground around the outer periphery of the structure other than the area to be constructed. In addition to requiring extra materials and personnel, safety cannot always be maintained due to the laminated load of the entire scaffolding frame.

The present invention relates to a scaffolding device that eliminates the above-mentioned drawbacks.According to the present invention, the scaffolding frame can be constructed at the same time as the cast concrete form panels of the structure are assembled. It is possible to ensure remarkable safety.

The following will be explained based on the drawings. As shown in Figs. 1 to 3, when constructing a veranda B that protrudes laterally from the construction main body A, first support 1°1 is erected, Place the large-drawn angle pipes 2, 2 on the top of the large-drawn angle pipe 2.
, 2, the square pipes 3, 3 for the joists are placed perpendicularly on them.

Furthermore, a formwork panel 8 is placed on the joist square pipes 3, 3, in which a hole 7 is bored through which a connecting rod 6 for connecting a fixing hardware 4 and an insert 5, which will be described later, is inserted.

and located above the perforation hole 7 of the formwork panel 8,
An insert 5 equipped with a tapered fastener 9 made of wood, synthetic resin, hard rubber, etc. is placed on the lower part of the insert 5, and the insert 5 is inserted through the perforation hole 7 of the formwork panel 8. The female screw threaded thereon and the connecting rods 6, 6 attached to the fixed hardware 4 are screwed together.

Next, the scaffolding receiver is attached to the square pipe 10, 10 so as to be held by the fixing hardware 4, 4, which is formed in a downward U-shape at the lower end of the connecting rod 6 which is threadedly connected to the insert 5 and suspended. After fixing the lower surface of the square pipe with the wedge piece 13 inserted between the slits (11, 11) and 12 (12, 12) on the opposing side walls of the fixing hardware 4, A lock pin 14 for the purpose is inserted into a hole drilled in the wedge piece 13 and locked.

Further, as shown in FIGS. 2 and 3, the wedge piece 13 is formed on the downward U-shaped side wall 11.11 of the fixed hardware 4.
．． Hole 15 located at the bottom of 12 and into which a safety round pin is inserted.
．． 15 is bored, and the removable safety round bar pin 16, which has one end locked to the side wall with a chain or the like, is inserted into the holes 15,15.

The safety round bar pin 16 temporarily receives the square pipe 10 on the safety round bar pin 16 when the wedge piece 13 fixing the square pipe 10 is removed.
The scaffolding holder is inserted in a removable manner to facilitate the work when withdrawing the rectangular pipe 10.

Next, the scaffolding supports that extend laterally and extend beyond the width of the veranda B constructed on the structure A are welded so that the ends of the rectangular pipes 10 are orthogonal to each other as shown in FIGS. Fit into the horizontal pipe 18 of the pipe fitting 17
Tighten by 9,19.

Similarly, the vertical pipe 20 of the pipe connector 17 has a scaffolding holder that protrudes and extends to the upper and lower balconies of the square pipe 1.
Insert the round pipes 21° and 21' into the upper and lower ends of the vertical tube 20 of the pipe connector 17 attached to the end of the 0.10 mm, and tighten with the poles 22 and 22.

In this way, the scaffolding support, which is successively extended to the outside of the upper veranda than the lower veranda by means of the pipe connector 17, tightens and integrates the upper and lower ends of the square pipe 10, so that the above-mentioned supports 1 ．． Even if the square pipes 3, 3 for the L joist and the large square pipes 2, 2 are removed, the square pipe 10 for the scaffolding support is still firmly supported by the insert 5 suspended from the lower balcony where the concrete has already hardened. .

Therefore, the above-mentioned connected upper and lower round pipes 21°21
′ means that even if the round pipe 21 of the lower veranda is pulled out from the pipe connector 17, the round pipe 21 of the upper balcony
1' maintains the same strength as when the connection is extended.

In addition, the ends of the square pipes 10 are connected and engaged with the round pipes 21 of the lower verandah by the pipe connectors 17, so that the scaffolding supports assembled on the upper veranda before concrete pouring are connected to the round pipes 21 of the lower veranda. Scaffold support is square pipe 1
Since the connection between 0 and the round pipe 21' is also tightly supported, the scaffold can be assembled and constructed firmly even before concrete is poured.

Next, the round pipes 21° 21 inserted into the upper and lower
’ Attach the orthogonal clamp 23.23 at an appropriate height position,
A handrail pipe is inserted through the clamp.

Incidentally, if necessary, each scaffolding support extending laterally and projecting from the width of the balcony may be used as a passageway or a workshop by laying a board on the square pipe 10.10.

In this way, the form panels 8 and the entire scaffolding frame are formed at the same time, and then concrete is poured onto the form panels 8 to construct the structure. After the poured concrete for balcony B has hardened, the scaffolding frame is attached to a part of the hardened concrete and assembled, and then work on the exterior walls of the structure is started, which is a waste of work time. consumption can be eliminated.

In addition, the present invention has the practical effect and excellent advantage of being able to perform incidental work such as arranging reinforcing bars for balconies, drainage facilities, fire walls, etc. at the same time, and furthermore,
Since the scaffolding frames can be easily assembled only at the site to be constructed without stacking the scaffolding frames from the ground, the amount of materials used can be reduced.

Of course, it is also possible to maintain reliable strength in terms of safety.

Note that a smooth concrete surface can be obtained by filling the hole of the fastener 9 created after collecting and removing these members with the same type of filler or mortar.
