Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is mainly applicable to renovations (additions and renovations) of general residential houses, which are affected by natural phenomena such as rain, snowfall, cold, and warmth. Moreover, it effectively blocks noise generated during construction, and does not scatter dust etc. to the outside.
The present invention relates to a construction scaffolding device that allows predetermined construction work to be carried out cleanly, safely, and quickly.

[Prior art]

As is well known, the reality is that ordinary residential houses are built by making the most of extremely small pieces of land, and the construction costs are currently quite high, so it is difficult to build new houses or buy new ones. As a result, people usually try to improve their living environment by repairing or expanding the house they currently live in.

By the way, there are strict restrictions when it comes to repairing or extending or renovating an existing house, such as having to carry out the intended work quickly without interfering with daily life. It has many problems compared to the case.

For example, if you are hit by rain or snow during construction,
Occasionally, typhoons are encountered, and scheduled construction work is frequently delayed due to natural phenomena such as cold and warm weather.

In addition, in the case of renovating a house in an urban area, even if there is no delay in the construction period due to the above-mentioned natural phenomena, since the house is built adjacent to the neighboring house, there are problems such as preventing materials from falling during construction, noise, and dust. Measures must be taken to remove the debris, and such ancillary work is required, which lengthens the construction period and sometimes necessitates changes to the construction period. As a result, not only the owner of the extension/renovation, but also the contractor for the construction, suffers a great deal of damage.

[Problem that the invention seeks to solve]

Therefore, in order to eliminate the above-mentioned problems, construction companies and so-called refurbishment companies have taken various measures to minimize delays in construction schedules, damage caused by construction changes, etc. caused by such natural phenomena, noise, dust, etc. The reality is that they are making proposals and searching for the best construction methods and means.

As an example, various proposals have been made for scaffolding devices to remove old materials from houses that are being expanded or renovated, or to transport new materials. It was constructed by assembling an underframe (pipe assembled into a tower shape) in an orderly manner using joint members.

Therefore, first of all, it is difficult to transport a large number of underframes to the construction site, and joint work at the site requires the mobilization of many workers because there are many joints, which requires a lot of labor and time. , which required expenses.

In particular, when the curtain members around these scaffolding devices are to be stretched after setting the scaffolding device, a tensioning ring or wire for tensioning the curtain members must be attached to the scaffolding device. The work was also extremely difficult.

Also, when extending or remodeling a house, some people install mesh curtains around the house to prevent the materials used for the extension or remodeling from falling onto adjacent houses, roads, etc.; There is a problem in that the construction work to install the mesh curtains around the mesh curtains is extremely difficult, requires many workers, and costs a lot of money. Since it is used as a roof, it has no effect on dustproofing or soundproofing, and there is no cover over the part corresponding to the canopy, so it is completely defenseless against rain, snowfall, wind, etc. Such means were also unable to solve the above-mentioned problems.

[Means and actions for solving problems]

The present invention has been made in view of the above-mentioned circumstances, and as a means thereof, a collapsible spacing member is constructed between frame-shaped erected members, and the sides of the erected member and the spacing member are extendable and contractible. A possible curtain member is stretched so that the curtain member expands or expands following the expansion and extension of the upright member and the spacing member, and the curtain member covers the entire outer periphery of the house to be expanded or renovated. It protects the construction space from natural phenomena such as rain, snowfall, and wind that can impede construction work in an extremely short period of time, eliminating delays in the scheduled construction period, as well as falling materials, dust, noise, etc. that occur during the construction work. effectively eliminates this and ensures a comfortable work space.

Furthermore, the present invention provides a construction scaffolding device that can assemble and dismantle scaffolding in a short time by automating all work steps such as installation, assembly (unfolding), and dismantling of construction scaffolding.

〔Example〕

FIG. 1, FIG. 2, FIG. 3 a, b, c, and FIG. 4 are explanatory diagrams showing one embodiment of the construction scaffolding device according to the present invention.

In the figure, 1 is a foundation guide member, and 2 is an upright member that moves along the foundation guide member 1 and is erected at a predetermined interval (this upright member is made of lightweight material such as duralumin, and has excellent strength). 3 is a spacing member that is constructed between the erected members 2 and can be bent at a central hinge (this spacing member is sometimes used as a scaffold for workers, etc.). , similar to the above-mentioned upright members, those that are lightweight and have excellent strength are used), 4
5 is a reinforcing member that suspends and reinforces the spacing member 3 when it is expanded, and 5 is a motor that moves the upright member 2 along the foundation guide member 1 (this motor runs within the foundation guide member 1). (A detailed explanation of the traveling means such as a chain is omitted.) 6 is a curtain member stretched inside and outside each of the upright members 2.

Hereinafter, the structure of the spacing member 3 and the reinforcing member 4 installed between the respective erected members 2, and the tensioning structure of the curtain member 6 stretched inside and outside each of the erected members 2 will be explained as follows. This will be explained in detail with reference to the drawings and FIGS. 3a, b, and c.

The upright member 2 has a frame-like structure, with vertical members 2a having H-shaped ends drawn inwardly arranged inside and outside, and horizontal members 2b arranged vertically at predetermined intervals.

Further, the spacing member 3 has a fixed hinge 3a on the side of the horizontal member 2b of the upright member 2, and is configured to be foldable in a "F" shape between the adjacent upright members 2, When unfolded, it is suspended by reinforcing members 4 placed on the left and right sides.

By the way, the locking end of the reinforcing member 4 on the side of the upright member 2 can be bent and expanded by fitting the slider 4a into the constriction recess 2c inside the vertical member 2a of the upright member 2. It is now running smoothly.

On the other hand, on the side of the upright member 2, there is a third curtain member 6 (in this embodiment, one is shown by a solid line and the other is shown by an imaginary line) that can be bent and extended. It is stretched as shown in Figures a, b, and c.

That is, the first locking of the curtain member 6 is performed by fitting the slider 6a into the outer throttle recess 2d of the vertical member 2a of the upright member 2, and the second locking is performed by fitting the slider 6a into the aperture recess 2d on the outside of the vertical member 2a of the upright member 2. This is achieved by fitting sliders 3c provided on the left and right sides of the hinge 3b of the spacing member 3 into guides 6b provided on the curtain member 6.

FIG. 4 shows a curtain member (hereinafter described as an awning 7 to distinguish it from the curtain member 6) stretched above the portion surrounded by each of the upright members 2 and the curtain member 6. This shows the configuration.

In the figure, 8 is a lift, and this lift 8 runs on a rail (rack type) 9 installed between horizontal bars arranged above the upright member 2, and is mounted in a cylindrical shape on the carrier 10. The awning 7 is expanded and stretched in the upper space surrounded by the upright members 2.

By the way, the lift 8 is driven by a geared motor 11 mounted in front of a carrier 10, and the driving force of the geared motor 11 is transmitted through a drive shaft to a pinion 12 meshing with the rail 9.
It is now being transmitted to

The above-described means for transporting and placing the lift 8 above the erecting member 2 includes, for example, a rail 9a similar to that described above on the side of the erecting member 2 at an appropriate position on the erecting member 2. The awning 7 is erected in an inclined manner, and the pinion 12 of the lift 8 is engaged with the awning 7 to perform a predetermined vertical movement to transport the awning 7 above the erected member 2.

Further, the transporting and placing means of the lift 8 may be a material elevating lift that has been widely used in the past. Any means may be used, and the present invention is not limited to the above-mentioned embodiments.

Furthermore, in the above explanation, a plurality of upright members 2 are set on the basic guide member 1, and these are expanded by the drive of the motor 5. At the same time, the curtain members 6 that will become the side walls are stretched, and finally the tent 7 is stretched. The explanation has only been made assuming that the curtain members 6 that surround the side walls are installed twice, inside and outside, to surround the entire house that is to be expanded or renovated. Between 6 and 6, in the summer, you can send in cold air to cool the work space so that you can work coolly, and in the winter, you can send in warm air to warm the work space so that you can work in it. For example, the effect of the present invention is not only the effect of eliminating only rain and snow by installing the awning 7 described above, but also the causes of cold and hot temperatures can be efficiently eliminated if the structure is configured as described above. And the effect becomes even more remarkable.

Furthermore, if an exhaust pump (vacuum pump) is installed between the curtain members 6, 6, and a predetermined intake hole is provided at an appropriate position on the inner curtain member 6, dust and the like that may be generated in the work space can be avoided. can be eliminated extremely effectively.

〔Effect of the invention〕

Since the present invention is constructed as described above, the scaffolding required for renovating an existing house can be achieved by setting a plurality of standing members on the foundation guide member and deploying them at predetermined intervals around the house to be expanded or renovated. The spacing members provided between the erected members are also deployed automatically as the erected members are deployed.

Therefore, since scaffolding can be constructed very easily and in an extremely short period of time, not only the construction cost but also the number of workers required for construction can be significantly reduced, and the cost for constructing the scaffolding can be extremely low.

Also, among the erected members developed above,
Since the curtain members that can be expanded and contracted are stretched on the outside, as the scaffold is constructed, the curtain members stretched on the inside and outside will also be expanded at the same time to cover the area around the targeted extension/renovation house.

Therefore, in cases where it is necessary to surround not only the scaffolding but also the surrounding area of an expanded or renovated house with a curtain member at the same time, the scaffolding and curtain members can be set in the same work process as described above. One work step is omitted compared to the curtain member tensioning work. Therefore, in the work of installing the curtain members, as in the case of constructing the scaffold, not only the construction cost but also the number of workers required for the curtain member tensioning work is significantly reduced, so the cost is extremely low.

Furthermore, each of the erecting members for the scaffold, etc.
All of the curtain members for external use are configured to be foldable or expandable, making them easy to transport, and since they can be made compact, they can be easily stored in a small storage space.
