[0002]

2. Description of the Related Art As is well known, when constructing a building such as a building, it is usual that a temporary living body is provided on an outer peripheral portion thereof in order to secure a working scaffold. Temporary living organisms are used not only for securing a working scaffold, but also for attaching a shield such as a sheet that covers the entire building for the purpose of drop curing, preventing scattering of dust to the outside, soundproofing, etc. It is.

[0003] Conventionally, the most common temporary living organisms are those that are standing on the ground using a so-called framework scaffold. However, when a building or the like is constructed, a great deal of time is required for assembling and dismantling the scaffold. Labor and cost. For this reason, a construction method in which the temporary living body is supported not on the ground but in a building under construction and installed, and the entire temporary living body is gradually rearranged upward as the construction progresses, is also being used.

[0004] Further, the temporary living body is usually provided only on the side of the building under construction. However, the temporary living body is provided with a roof portion which covers the upper part of the building under construction. Some of them have been developed to make the site all weather.

[0005]

By the way, the conventional temporary living body and the construction method using the same as described above include:
The following problems exist. In other words, the temporary living body used when constructing a building such as a building, has a plurality of columns (so-called masts) provided with a climbing function for ascending upwards on the building under construction in order to be rearranged upward. The temporary living body is supported on these columns.
As a result, the entire temporary living body becomes very large and heavy. Such a large-scale temporary living organism is not worth the cost except for a large-scale high-rise building, and therefore it has been difficult to apply it to a medium-sized or smaller building. In addition, since the supporting column supporting the temporary living body stands inside the construction floor, the work space may be sacrificed, and the development of a technology capable of solving these problems has been desired. .

Further, when the above-mentioned temporary living body is to be applied particularly to a small-scale building or the like, the following problems also occur. First, temporary living organisms are sometimes equipped with overhead cranes for lifting and transporting materials.However, when applying temporary living organisms to small-scale buildings, only temporary living organisms are needed. In addition, if the cost of the overhead crane etc. is included, it is often not worth the cost. In addition, when the temporary living body is to be suspended, especially when dismantling, in small buildings, the site may be so narrow that a crane or the like cannot be used. There is also.

SUMMARY OF THE INVENTION The present invention has been made in view of the above points, and is a low-cost and simple temporary living body which can be effectively applied to a small-scale building, and a building using the same. It is an object to provide a construction method.

Each wire fixing jig 14 grasps and fixes the wire 11 so that it cannot be displaced in the vertical direction. Then, with four winches 10 of the four-sided wire winch mechanism 4,
The four wires 11 are simultaneously wound at a constant speed. Then, the living body 3 is raised. When the living body 3 rises to a predetermined level, the winding of the wire 11 by the winch 10 is stopped, and the support member 9 is attached to a mounting bracket (not shown) provided in the building 1. 9 is also fixed to the living body 3. As a result, the living body 3 is connected to the building 1 by the support member 9 and the load is supported by the building 1, so that the wire fixing jig 14 is removed as shown in FIG. Release the fixation of 11.

Thereafter, as described above, the work of constructing each floor of the building 1 using the wire / winch mechanism 4 as a wire crane and the upward movement of the temporary living body 2 using the wire / winch mechanism 4 as a refilling mechanism. Work alternately, and assemble building 1 upwards,
Work up to the top floor.

As shown in FIG. 7A, after assembling the building 1 to the top floor, the roof 7 of the living body 3 is first removed. Subsequently, the wire fixing jig 14 is attached to the building 1 to fix the wire 11, and the support member 9 is removed. By pulling out the wire 11 from each winch 10 in this state, the living body 3 is lowered along the building 1.

As shown in FIG. 7 (b), when the upper end portion of the side wall portion 6 is substantially at the same level as the roof of the building 1, the descent is stopped, the support member 9 is attached, and the living body 3 is removed. The side wall 6 is supported by the building 1. Then, the four wires 11 of the wire / winch mechanism 4 are fixed on the roof of the building 1 using a fixing bracket (not shown) or the like. In this state, the outer wall of the building 1 is constructed on the side wall 6 of the living body 3.

Subsequently, the support member 9 is removed. Then, the side wall 6 of the living body 3 is suspended from the building 1 by the four wires 11. The four winches 10 of the wire / winch mechanism 4 simultaneously feed out the four wires 11 at the same speed, and the living body 3
Is lowered. Then, in this way, each time the living body 3 is lowered by the predetermined size by the wire / winch mechanism 4, the supporting member 9 is attached and the living body 3 is attached to the building 1 as shown in FIG. Let them support you. Then, in this state, the outer wall of the building 1 is constructed on the side wall 6 of the living body 3.

Regarding the above, a space truss material (truss structure) may be arranged not only at the corner 6a of the side wall portion 6 but also at other portions as necessary, and any space truss material may be used. May be. The frame scaffold forming the other portion 6b of the side wall portion 6 is provided, for example, in Japanese Patent Application No. Hei.
Unit truss materials such as 207829 and Japanese Patent Application No. 8-10428 may be used. Further, the roof part 7 has a membrane roof structure, but any structure may be used as long as it is lightweight and easily detachable.

Further, such a living body 3 is attached to the building 1.
The support member 9 to be fixed to the housing 1 is not limited at any place, and the number of the support members 9 that can sufficiently support the load of the living body 3 may be appropriately arranged on the side wall surface of the building 1 or the like. Good. Further, the supporting member 9 is provided with a mounting bracket (not shown) on the building 1 and attached to the building 1. For example, a hole is made in the outer wall surface of the building 1, and the tip of the supporting member 9 is inserted into this hole. You may insert it.

The same applies to the wire / winch mechanism 4, and the installation location is not limited to the four corners of the building 1. Regarding the configuration of the wire winch mechanism 4, for example, other than the wire fixing jig 14 may be used for fixing the wire 11. By the way, the loading hook 13 is attached to the wire / winch mechanism 4.
The lifting hook 13 is provided with an elevating function like a so-called hoist crane.
The winch mechanism 4 may be configured to move the loading hook 13 only in the horizontal direction.

Further, as for the building 1 to which the temporary living body 2 is applied, there is no limitation on the size or shape of the building, and any building can be used as long as the wire 11 can support the load at the time of rearrangement or material transport. It is also possible to apply to.

In addition, a projecting portion or an opening may be provided on the outer peripheral portion of the temporary living body 2 to protrude outward, for example, and this may be used as a material carrying-in port.
