DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rebuilding system and a rebuilding method for rebuilding an existing building, and more particularly to a rebuilding work area that can be limited to a local area while maintaining the functions of facilities in the existing building. The present invention relates to a remodeling system and a remodeling method that can be remodeled.

[0002]

2. Description of the Related Art Conventionally, when rebuilding an existing building having a production facility or the like inside, such as a factory, the inside of the existing building becomes outside when the existing building is demolished. Production facilities, etc., must be relocated to another location, and the operation of the production facilities must be suspended during the renovation work. The renovation of the existing building was accompanied by a great disadvantage for the business operator.

As an example of a method of remodeling an existing building while avoiding such disadvantages, there is a method of constructing a new building covering the entire outside of the existing building before dismantling the existing building. In this method, a sliding rail is laid above an existing building in operation, and a roof truss of a new roof is laterally drawn on the rail, thereby covering the entire outside of the existing building to form a new building. Build and then
Demolition work of the existing building is performed inside this building. According to this method, since the existing building is covered in advance by the new building, when the existing building is dismantled, the facilities such as the internal production facilities are not exposed to the outside and the operation of the production facilities is interrupted. The existing building can be renovated without any change.

[0004]

However, in the method of disassembling the existing building after previously covering the entire existing building with the new building, the new building is once constructed.
After the completion of the construction work, the existing building will be dismantled, etc., so the construction work of the new building and the dismantling work of the existing building will be separate, and the construction period of the entire renovation work will be prolonged. In addition, the demolition work of the existing building inside the new building has been accelerated along with the shortening of the construction period because the entire existing building is already covered with the new building. Since they are performed collectively, the range of impact of the demolition work is widened, which may result in sacrificing production activities in the existing building.

Furthermore, in the above-mentioned method, since the entire existing building is covered by the new building and dismantling is performed inside the existing building, the new building needs to be larger than the existing building. When the site area of the building is enlarged and the area cannot be secured, it has been difficult to perform the renovation work by the method. In addition, there is a problem that the rebuilding cost increases because the new building is forced to be large.

[0006] The present invention has been made in view of the above problems, and in the remodeling work of an existing building, the work affected area is partially stopped to maintain production activities.
An object of the present invention is to provide a rebuilding system and a rebuilding method for an existing building that can shorten the period of rebuilding work and also achieve a reduction in rebuilding costs.

[0007]

In order to achieve the object, an existing building remodeling system according to the present invention is a remodeling system for renovating an existing building, wherein a plurality of the existing buildings are arranged along a longitudinal direction of the existing building. A new pillar to be dismantled, and provided on the new pillar so as to cover the upper part of the existing building to be dismantled and to be slidable along the longitudinal direction of the existing building, and dismantle the existing building sequentially while being moved. And a dismantling part for pulling a new roof covering the dismantled part on the new pillar, and a working part provided in the moving direction of the dismantling part and sequentially constructing the new roof pulled by the dismantling part. It consists of:

[0008] The rebuilding method of an existing building according to another invention is as follows.
A rebuilding method for rebuilding an existing building, the step of arranging a plurality of new pillars along a longitudinal direction of the existing building,
Installing a dismantling part on the new pillar, which covers an upper part of the existing building to be dismantled, and is slidable along the longitudinal direction of the existing building; and A step of installing a working unit for constructing a new roof towed by the demolition unit, and moving the demolition unit while towing the new roof on the new pillar, sequentially dismantling the existing building and The method includes a step of covering the dismantled portion with the new roof, and a step of fixing the new roof to the new pillar to form a permanent roof.

[0009]

According to the rebuilding system and the rebuilding method for an existing building of the present invention, the dismantling portion which is slid and moved on a plurality of new pillars arranged along the longitudinal direction of the existing building is located above the existing building to be dismantled. The existing building will be dismantled sequentially while covering the building, and the dismantled part will also pull the new roof covering the dismantled existing building part. Will not be exposed. Also, in the rebuilding work of the existing building, the dismantling section is to sequentially dismantle the building while sliding along the longitudinal direction of the existing building, and the working section for sequentially constructing the new roof is the dismantling section. In addition, the new roof will be pulled by the dismantled part on the new pillar, so that the area where the renovation work affects the existing building may be stopped locally. it can. For these reasons, the existing building can be renovated without interrupting the operation of the facilities inside the existing building.

[0010] Further, the dismantling section is slid and moved along with the dismantling work, and the new roof is towed in accordance with the slide movement. The dismantling work of the existing building and the construction work of the new building are performed in parallel. As a result, the construction period of the entire renovation work can be shortened. In addition, the new roof will be installed after the dismantling of the existing building by the dismantling section, so it will not be a large one that covers the existing building,
It does not need to increase the site area of the building, nor does it increase the cost of renovation.
