Description

The present invention relates to a temporary enclosure curing device in which a sheet such as a blue sheet is stretched on the temporary enclosure to prevent mud scattering and noise.

At construction sites, especially in the city, "mud scattering" and "noise" become problems during pile construction.

There is a very high possibility that mud adhering to the excavated rod part of the pile driver will scatter from high places.

Therefore, it is common to install a blue sheet or the like on the temporary enclosure built around the construction site to prevent scattering, and assembling is a long single pipe as a support on the inside of the temporary enclosure construction site. Stick out the pipe and fix it. (Match to the length of the blue sheet)

A wire is stretched over the protruding single pipe, and a blue sheet is stretched on this like a curtain rail.

However, since the temporary enclosure can only withstand its own wind load, it is necessary to fold the shatterproof blue sheet because it is vulnerable to strong winds when there is no mud, dust or noise such as piling work except during work. However, it may not open and close smoothly, it looks bad, and its strength is opaque.

The following patent documents are proposed to provide a temporary enclosure structure that reduces the addition rate of SPM (suspended particulate matter) and the like on the surrounding environment and minimizes the impact on construction and the installation cost. ..
Japanese Unexamined Patent Publication No. 2002-89048

In Patent Document 1, as shown in FIG. 14, the temporary enclosure main body 2 is erected on the ground G, and the upper end portion 3a of the fixed support 3 erected from the ground G is projected above the temporary enclosure main body 2. A screen portion 4 that can be stored and deployed is provided so as to be supported by the upper end portion 3a of the fixed support column 3. Then, when the screen portion 4 is deployed, the screen portion 4 is formed so as to continuously extend to a certain region above the temporary enclosure main body 2.

The screen portion 4 has a configuration including a screen main body 5 formed of a sound insulating material and a pair of wires 6 and 6 temporarily provided between the fixed columns 3 to support the screen main body 5.

The screen body 5 of the screen portion 4 is formed in a bellows shape, and its upper end edge portion 5a and lower end edge portion 5b are movably supported along the upper and lower wires 6 and 6, whereby the wire 6 is supported. , 6 is foldable and unfoldable. When the screen main body 5 is expanded, the screen portion 4 continuously extends to a certain area above the temporary enclosure main body 2.

When such a temporary enclosure structure 1 is used in the field, for example, when there is no wind having a large influence on the ground of the SPM, the screen body 5 is expanded along the wires 6 and 6 to provide the screen unit 4. It is positioned continuously above the temporary enclosure main body 2.

As a result, the height of the temporary enclosure structure 1 itself becomes substantially high, and the diffusion of SPM to the ground can be reduced. Further, in a strong wind with a large diffusion of SPM, the screen main body 5 can be folded and stored along the wires 6 and 6 so that only the temporary enclosure main body 2 portion of the temporary enclosure structure 1 can be used.

It is also proposed in Patent Document 1 that a wire is erected between the upper ends of the fixed columns 3 and that the screen body is formed by a roll screen that can be wound and deployed with the wire as a winding shaft. There is.

The following patent documents have been proposed regarding a curing net stretching device in which a curing net is detachably attached and stretched on the upper part of a pipe column such as a temporary enclosure, and as shown in FIG. 15, a pipe such as a temporary enclosure 10 or the like is proposed. A plurality of support brackets 21 rotatably fitted to the upper end of the support column 11, a plurality of net tensioning pipes 22 separately or integrally slanted above the support bracket 21, and net tensioning. A curing net 23 attached to the pipe 22 and stretched, and a stretching strip 15 connected to the tip of the net stretching pipe 22 for operation and fixing were provided.

When it is folded or disassembled and removed, each net tensioning pipe 22 is rotated to the upper part of a temporary enclosure or the like by the tensioning strip 15.

In the case of Patent Document 1, the screen main body 5 formed in a bellows shape remains protruding above the temporary enclosure main body 2 in the folded state, and even if it is a roll screen, the wound state is the temporary enclosure main body 2. I'm still on a business trip upwards.

Further, the folding and winding operations must be performed at an upper position of the temporary enclosure main body 2, and quick and safe work cannot be performed. To make it operable downwards requires a complex mechanism.

In addition, even if it is a screen body or a roll screen, a special special one is required, and it is not possible to use an inexpensive general-purpose product such as a blue sheet.

In the above Patent Document 2, since the curing net is stretched and not the sheet stretched, it is not suitable for preventing "mud scattering" and "noise".

Further, as in Patent Document 1, the folded one remains above the temporary enclosure, and the work is performed by tilting the net tensioning pipe 22 which is a support column, so that the folding work cannot be performed quickly and safely.

An object of the present invention is to solve the inconvenience of the above-mentioned conventional example, and to install a sheet on a temporary enclosure to prevent scattering and to take noise measures.

In the present invention, such a temporary enclosure 7 is provided with a support column 17 made of a C-shaped channel material having a front opening so as to stand up largely upward. The columns 17 are provided at intervals of, for example, about 4 m.

The stanchions 17 are formed by connecting two struts with the same opening surface side by side side by side, and the locking plates 18 forming the insertion holes of the pipe stanchions 8 are projected horizontally at the lower part with a vertical space between them. A hook-shaped locking plate 19 was provided horizontally in the middle portion.

A vertical piece 18a is provided in a flange shape on the locking plate 18 in which the insertion hole is formed, and the tip of the vertical piece 18a comes into contact with the pipe column 8 inserted into the insertion hole.

The details of the hook-shaped locking plate 19 are shown in FIGS. 9 and 10. The locking plate 19 is a pair of left and right parallel plates connected by the horizontal plate 19a and the vertical plate 19b, and the horizontal pipe 9 is engaged. A notch hole in the matching downward opening is formed.

Further, a fixing bolt 20 having a nut fixed to the vertical plate 19b is provided so as to face the notch hole so that the tip thereof can be pressed against the peripheral surface of the horizontal pipe 9.

A horizontal roller 24 formed by fitting a pipe body 24b to a shaft bolt 24a is attached to the tip end portion of the support column 17. The horizontal roller 24 is provided by a support flange plate 25 at the tip of the support column 17 so as to project toward the front side of the support column. Instead of the horizontal roller 24, a normal vertical roller may be used as a guide roller.

A wheel 26 that moves up and down along the channel material is provided with the opening surface edge as a rail for the channel material constituting the support column 17.

The wheel 26 is provided on the holding plate 27 by an axle 26a, and the opening surface edge of the channel material engages with the groove of the vehicle body so that the wheel 26 is vertically and vertically fitted into the channel material constituting the support column 17, and half of the wheel 26 is inside the channel material. The other half is exposed to the outside of the channel material.

One end of the string 30 is locked to the holding plate 27 of the wheel 26, and the string 30 is hung on the horizontal roller 24 through the channel material and hung as a pull string by the support column 17. As will be described later, a plurality of wheels 26 are arranged one above the other, and the other end of the string 30 is locked to the holding plate 27 of the lowermost wheel 26.

The string 30 can be used not only for fiber ropes but also for wire ropes, chains and the like. Further, the string 30 may be connected endlessly.

The axle 26a of the wheel 26 provided on the holding plate 27 uses the protruding end as a locking pin of the seat 31 so that the edge of the seat 31 is stopped here.

When the sheet 31 is shown in FIG. 5, it is a horizontally long rectangular sheet, and a blue sheet or a flameproof sheet is used to form a locking hole 31a by a dovetail around it. Sheets made of other materials can also be used.
