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, the scaffolding frames used when constructing overhanging parts such as balconies of high-rise concrete structures were: ■ Laminated from the ground around the outer periphery of the structure and erected over the entire surface, or ■ Construction of balcony overhangs. After the poured concrete has hardened, it is then fixed to the lower part of the concrete of the structure or balcony, which not only reduces work efficiency but also causes damage to the outer periphery of the structure other than the area to be constructed. The necessary scaffolding frames must be stacked and erected from the ground, which requires extra materials, personnel, etc., and has the disadvantage that safety cannot be maintained at all times due to the stacked load of the entire scaffolding frame.

In addition, in case (2), there was a drawback that there was no work scaffolding for assembling the formwork.

In order to compensate for these shortcomings, a scaffolding device was devised in which a scaffolding frame is installed at the same time as the cast concrete formwork panels of the structure are assembled.

However, even with the scaffolding equipment mentioned above, the scaffolding framework required to construct an overhanging veranda was integrated with the support, joists, formwork, etc.
As mentioned above, when removing supports, joists, formwork, etc., the scaffolding frame must be removed, and when carrying out subsequent work on the balcony, such as spray painting, the scaffolding frame must be reassembled. It was found that the disadvantage is that it requires double effort to configure.

Therefore, the present invention compensates for these shortcomings and provides a scaffolding device that is quick and has sufficient safety. Even when removing formwork panels, there is no need to remove them.
The scaffolding frame can be used continuously for the bond and subsequent finishing work on the veranda.

Explaining the following based on the drawings, the one shown in Figs. 1 to 3 uses a square pipe for the drawer, and the implementation of the scaffolding device when a horizontal round pipe for scaffolding is suspended and supported from the square pipe. This is an example.

When constructing a verandah B that projects laterally from the concrete structure A, a large square pipe 1 is placed on a support, and a joist square pipe 2 is placed perpendicular to the large square pipe 1. , furthermore, formwork plates 3 are placed and arranged.

Each edge of the formwork plate 3.3 has a semicircular arc notch through which a connecting rod 6 screwed with a fastener 5 attached to the insert 4 is inserted, and the semicircular arcs are mutually connected to each other on the formwork plate. The edges abut to form a circular hole 7.

Further, at the tip of the connecting rod 6, a collar 11 is formed which has a diameter slightly larger than the diameter of a hole 10 drilled in a horizontal part 9 of a hanging device 8 of a horizontal scaffolding member having an inverted shape, which will be described later. The connecting rod 6 is fitted into the hole 10 so as to allow some movement.

Note that the hole 10 is bored at an eccentric position in consideration of the load balance of the horizontal scaffold round pipes 12 and 12 suspended by the suspension tool 8 of the scaffold horizontal member.

Next, on the suspension device 8 of the horizontal scaffolding member, two long and short side plates 13° 13' on the left and right are bent with the horizontal part 9 in the middle, and are bent from the middle of the longitudinal side plate 13 toward the tip. A clamp mounting plate 14 is attached to the mounting plate 14, and a clamp 15.15 is provided on the back side of the mounting plate 14.

Furthermore, slits 16.16 are bored near the top of the two left and right side plates 13, 13', and the slits 16.16
A wedge piece 17 is inserted through the hole 6.

In this way, the suspending device 8 of the horizontal scaffolding member constructed in this manner is now placed within the semicircular arc cut out at the edge of the uppermost form board 3 via the insert 4 and the fastener 5. While abutting the connecting rod 6 screwed together, a large corner hole 4. Place Eve 1 astride it to store it.

Then, it is inserted through the slits 16.degree. 16 formed in the side plates 13 and 13' and fixed to the large draw angle pipe 1 with the wedge pieces 17.

Note that the code C indicates poured concrete. Next, the 1 which was suspended and supported by straddling the large square pipe 1 in this way
A horizontal round pipe 12.12 for a scaffold is supported by a clamp 15.15 attached to the longitudinal side plate 13 side of the horizontal scaffold suspension member 8 by a mounting plate 14 in a rear-like manner.

Note that FIG. 3 shows another embodiment, and in this embodiment, a corner piece of wood 1' is used for the main drawer.

That is, the scaffolding horizontal material suspension device 8 is different from the above-mentioned upside-down shape, and has a connecting rod 6 that is screwed together with the insert 4 and the fastener 5, and has a 1,000-arm-shaped main puller. A hooking piece 18 is provided, and a bolt 19 is provided on the hooking piece 18 for securing and supporting the large square piece 1'.

A clamp 15 that supports the horizontal round pipe 12 for scaffolding is attached to the lower end of the connecting rod 6.

Furthermore, what is shown in FIGS. 4 to 7 is another embodiment of the scaffolding device in which a round pipe is used for the pull-out, and a horizontal round pipe for scaffolding is suspended and supported from the round pipe.

When constructing a veranda B that protrudes laterally from the concrete structure A, the two large round pipes 20.20 placed on the supports and the two large round pipes 20.20 perpendicular to the large round pipes 20.20 are The joist square pipes 2 are placed one after another, and the formwork board 3 is placed on the upper stage.
is placed and configured.

A semi-circular notch is formed on each edge of the formwork plates 3, 3, through which the scaffolding frame suspension rod 21 screwed with the fastener 5 attached to the insert 4 is inserted, and the semicircular arc is The edges of the frame plates 3, 3 abut against each other to form a circular hole 7.

Two washer pieces 23.23 for tightening the two round pipes 12.12 of the horizontal scaffolding frame are attached to the lower end of the suspension rod 21 for the scaffolding frame screwed together with the insert 4.

In addition, as mentioned above, the hanging rod 21 for scaffolding frame of the present invention is used when two round pipes 20 and 20 are used as the main lumber, and is as shown in FIGS. 6 and 7. It is only through the structural bracket 24 that the two can be attached.

That is, the bracket 24 is formed by folding back an insertion hole 25 having a circular dimension slightly larger than the diameter of the suspension rod 21 for the scaffolding frame in the center of a piece of iron, and a hole is formed in the middle part between the insertion hole 25 and the other end. , two bent pieces each having an insertion hole 27 for the washer bolt 26 are welded into one piece, and the washer bolt 26 is welded into one piece.
There are two large round pipes 20.20 on the left and right of the insertion hole 27.
Shallow circular arcs 28, 28 are cut out in order to stably abut the two.

On the other hand, a stopper ring 29 for positioning the stopper ring 29 to be engaged with the bracket 24 is fitted at an appropriate length in the middle of the suspension rod 21 for the scaffold frame, which is inserted through the insertion hole 25 formed in the bracket 24.

The fitting position of the stopper ring 29 is such that the length of the insert 4 is buried in the poured concrete (C).

The insertion hole 25 of the bracket 24 formed in this way
The suspension rod 21 and the washer bolt 26 are respectively inserted into the insertion hole 27 in advance to form a combination, and several combinations of the suspension rod 21 are cut into the edge of the form plate 3 to form a semicircular arc. At the same time, a large round pipe 20.20 is brought into contact with the two shallow notched circular arcs 28.28 of the bracket 24, and an insertion hole 27 is inserted above the large round pipe 20.20. Type 3 washer 30 welded to washer bolt 26
The bolts 26 protruding from the insertion holes 27 of the brackets 24 are screwed together with nuts to firmly tighten and support the assembled body on the round pipes 20 and 20.

At this time, the suspension rod 21 is suspended from the upper opening periphery of the insertion hole 25 of the bracket 24 by the stopper ring 29 .

In this way, at the lower ends of the hanging rods 21, 21, which are tightly supported by the large round pipes 20, 20. Washer piece 23.23 having the same shape as washer 30
is attached, and the two horizontal round pipes 12, 12 for scaffolding are tightly supported by the washer pieces 23, 23.

In addition, the Oibikimaru pipes 20, 20, 20, 20', 20' and the respective brackets 24, 24
