Is done.

[0004]

By the way, when the curtain wall described above has aged, for example, when a water leakage accident occurs, conventionally, a scaffold is newly set up for repair.
Even if the scaffold is erected only at the identified leak point, the scaffolding requires a lot of time and money, or even if the leak point is visibly partial. However, if it was decided that a thorough inspection was necessary, scaffolding had to be installed over the entire surface of the curtain wall, which required enormous cost.

The present invention is not limited to this. For example, when the curtain wall is installed, the power equipment and information communication equipment installed in the existing building, and other air conditioning and water supply / drainage equipment are functionally old. In order to improve these functions, that is, to make them intelligent,
It may be possible to arrange equipment members for realizing the functions required for the intelligentization, that is, equipment members such as power and communication cables, air conditioning pipes, water supply and drainage pipes, between the outer wall surface of the existing building and the curtain wall. However, the problem is how to maintain the equipment members when such measures are taken.

In view of such circumstances, the present invention not only performs maintenance on the curtain wall when repairing the outer wall surface of an existing building with the curtain wall,
For example, for the purpose of providing a refurbished structure of an existing building that allows maintenance of facility members and the like placed between the curtain wall and the outer wall surface to be made intelligent, as needed. There is.

[0007]

The reconstructed structure of an existing building according to the present invention, which has achieved the above-mentioned object, has a predetermined space between the outer wall of the existing building and the outer wall surface through the supporting bone. A curtain wall is installed by forming a space portion, and in the space portion, horizontal passages are provided at predetermined intervals in the vertical direction, and vertical ladders are arranged over the upper and lower horizontal passages. There are features.

[0008]

According to the above characteristic structure, since the scaffolding equipment by the combination of the horizontal passage and the vertical ladder exists on the back side of the curtain wall, not only the curtain wall but also the curtain wall and the outer wall surface of the existing building. It is possible to immediately carry out maintenance on the equipment members and the like arranged between the two, if necessary.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 show a curtain wall A for renovation arranged so as to cover the outer wall portion of an existing building except for the emergency external stairs 1, and as shown in FIGS. Supporting bones 3 are provided on the outer wall surface 2 at a predetermined interval, and a cuboid 4 is attached to the supporting skeleton 3 on the outer wall portion of the existing building. The newly installed wall panels 6a and 6b and the window panel 6c are provided so as to fill the lattice-like space formed by the uprights 4 and the blinds 5, and some of the wall panels 6b are curtained. Maintenance for the inside of the wall
The opening / closing wall for inspection is configured to be openable / closable outward through a hinge 7.

The supporting bone 3 is provided with an L-shaped first fastener 8 whose position can be adjusted in the vertical direction by a bolt 9 and a nut 10 which are embedded in the outer wall of an existing building. The fastener 8 is provided with a second fastener 11 whose position is adjustable in a direction orthogonal to the wall surface, and a bracket 12 for upright mounting is fixed to the second fastener 11.

At the same time as the renovation of the outer wall portion by the curtain wall A, the existing building is being made into an intelligent building. That is, as shown in FIG. 2, while the cubicle 13 is installed on the roof R of the existing building, on the indoor side,
An air conditioner 14 typified by a wall-mounted or floor-standing cooler and an air conditioner air blower, and other information communication equipment and water supply / drainage equipment (not shown) are installed, and equipment members (power cables, power cables, etc.) for the cubicle 13 of these various equipments are installed. , Electric wires and optical cables for communication, ducts for air conditioning, water supply and drainage pipes, etc.), that is, the equipment members 15 for realizing the functions required for intelligent installation are arranged between the outer wall surface 2 of the existing building and the curtain wall A. ing.

Specifically, in the space B formed at a predetermined interval between the outer wall surface 2 and the curtain wall A via the support bone 3, the support bone 3 is used and a predetermined vertical direction is used. The horizontal passages 16 for maintenance are arranged with a space between them, and the elevating space a is provided in a part of the horizontal passage 16 at different positions in the upper and lower parts, and the upper and lower horizontal passages are provided through the elevating space a. A vertical ladder 17 extending over 16 and 16 is provided, and a handrail 18 is provided so that movement from the horizontal passage 16 to the vertical ladder 17 (reverse movement) can be performed safely.

Then, a part b of the horizontal passage 16 is cut out, a bracket 23 is provided over the first fasteners 8, 8 of the supporting bone 3 facing the cutout part b, and the equipment member 15 described above is attached to the bracket 23. And each horizontal passage 1 through the landing 19 of the external stairs 1
A door 20 is provided to allow access to and from the vehicle.
