Description

[Detailed Description of the Invention] The present invention relates to a saddle device for a passage scaffold placed after slab reinforcement is placed.

When pouring reinforced concrete, slab reinforcements 2 are arranged in a spider web shape above a temporary floorboard 1 in a slightly floating state, as shown in FIG.

After this slab reinforcement is completed, when performing formwork work, electrical equipment work, concrete pouring work, etc., if a worker stands directly on the reinforcement, the reinforcement will be disturbed, and concrete will be poured with this disturbed reinforcement. If this is done, there is a risk that the concrete will crack, allowing vibration and sound to be transmitted directly to the downstairs floor, or causing water leakage.

Therefore, conventionally, as shown in Fig. 1, only single saddles 3 are placed at predetermined intervals, scaffolding boards 4 are placed on top of these saddles 3 to create a passage, and formwork work is carried out on top of this. They were also doing electrical equipment work and laying out concrete delivery pipes5.

However, in this conventional method, when placing the saddle 3 and placing the scaffolding board 4 on the saddle 3, it is necessary to stand on the reinforcing bars, and when placing concrete, it is necessary to stand on the reinforcement. In addition, when moving or rearranging the scaffolding, it is necessary to stand on the reinforcing bars, and it takes a lot of time to arrange and change the scaffolding, resulting in poor work efficiency.
There have been various drawbacks such as the saddle 3 being bulky when stored after the construction is completed.

The present invention was made to improve such conventional drawbacks, and the legs are formed by bending a metal plate into a V-shape.
A scaffold board holding part is formed on the upper part of this leg part to constitute a saddle, and the scaffold board is fitted into this saddle.

Embodiments of the present invention will be described with reference to the drawings.

In FIGS. 2 and 3, a metal plate such as an iron plate having a predetermined width and thickness is bent on both sides to the same side in a V shape, and the bent pieces 6 and 7 form a leg portion 8. Also,
The upper portions of the bent pieces 6 and 7 are folded in the same direction at a predetermined distance from each other to form the scaffold board holding part 9.

Through holes 10° and 11 are formed in the middle of the bent pieces 6 and 7 that form the leg portion 8, respectively, and bolts 12 are inserted from inside and tightened into the through holes 10 and 11. 13.

The tightening bolts 12, 12 are connected to each other by a connecting rod 14 in order to prevent the legs 8 from bending and spreading when a load is applied from above.

The saddle 15 is constructed in this way.

In such a configuration, the wing nut 13 of the saddle 15 is loosened, and a scaffold board 16 made of plywood or the like is inserted between the scaffold board clamping parts 9.

Depending on the length, thickness, load applied from above, etc. of the scaffolding board 16, as shown in FIG.
~5 saddles 15 are used.

Next, when the wing nut 13 is tightened, the bent pieces 6 and 7 of the leg portion 8 approach each other, so that the scaffolding plate holding portion 9
The distance between the saddles 15 is also narrowed, and the saddles 15 are firmly attached to the scaffolding boards 16, forming a scaffolding platform 17.

In the case of FIG. 2, the case where the upper folded pieces 7 forming the scaffold plate holding parts 9 of the opposing saddles 15 are integral with each other has been explained, but as shown in FIG. 6 may be integral with each other, and if the metal plate forming the saddle 15 is strong and there is no risk of it breaking and spreading due to a load from above, the connecting rod 14 is not necessary, and the connecting rod 14 is not required. The nut 13 may be screwed together from the inside.

Further, in the case of FIGS. 2 and 7, the two opposing saddles 15 are integrally constructed, but as shown in FIG. 8, they may be separated.

A concrete example of using the scaffolding platform 17 composed of the saddle 15 and the scaffolding board 16 constructed in this way at a construction site will be explained with reference to FIGS. 5 and 6. However, the joist pipe 19 and the large square timber 2
It is placed on top of 0 and supported by the lower pillar 21 from below.

Slab strips 2 are stretched over the floorboard 1 in a spider web shape, slightly floating above the floorboard 1.

On the other hand, a predetermined number of saddles 15 are attached to the scaffolding board 16, and a fourth
A scaffolding platform 11 as shown in FIG. 1 is formed in advance.

Scaffolding platforms 17 are arranged alternately in corridors, slab reinforcement locations, etc. inside the building to form passageways.

In particular, concrete delivery pipe 5 for concrete pouring
A stage is formed by arranging a plurality of concrete pipes at predetermined intervals, so that the flexible pipe section at the tip of the concrete delivery pipe 5 can swing from side to side.

To place a scaffolding platform 17 at a location where slab reinforcement is arranged, first place one scaffolding platform 17 from the location where slab reinforcement is not arranged.
The T is installed so that the leg part 8 of the saddle 15 does not rest on the slab reinforcement 2, and then a worker stands on this scaffolding platform 11 and installing the scaffolding platforms 17 one after another.

After the scaffolding platform 17 is installed and the passageway is formed, concrete is poured next from the end.

From the position where concrete pouring is completed, the scaffolding platform 17 is moved back and forth as shown by the arrow in FIG. 6, and the entire concrete is poured.

Since the present invention is constructed as described above, by using this saddle 15, it is possible to make a lightweight and easy-to-assemble scaffolding platform.In addition, it can be used for slab construction during formwork work, electrical equipment work, concrete pouring work, etc. A passage can be created without disturbing the reinforcement arrangement, so cracks in the concrete and various other problems caused by this do not occur.

It is also possible to efficiently change, move, and remove passages and stages.

Furthermore, the saddle 15 and the scaffolding board can be reliably attached by tightening the bolts 12 between the bent pieces 6 and 7, and disassembly is also easy. Since the saddles 15 are connected with each other, even if the saddle 15 is a relatively thin metal plate, it has an excellent effect that it will not bend even under a considerable load.
