Abstract

<P>PROBLEM TO BE SOLVED: To provide a construction method for effectively using a stairs space by arranging a common corridor and an elevator without hindering the passing of residents when performing step height eliminating work in an existing stairs room type apartment house. <P>SOLUTION: A common corridor building is constituted of and constructed by the common corridor, the elevator and stairs adjacently to an existing apartment house. A common passage is extended to one side half of the uppermost floor stairs of an existing building from a corridor of the uppermost floor of the newly built common corridor building. A passing passage of the residents is secured, and afterwards, just under stairs are removed to similarly transfer to work of the lower floor. A generated space is also used for arranging a pipe space, a small elevator and an alcove. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

The present invention is a method of installing a common corridor, an elevator, and a staircase in an existing staircase type apartment house so as not to hinder the passage of residents when performing leveling work, and effectively using the generated space. .

Conventionally, there is a step disclosed in Patent Document 1 as an example of the step elimination work in an existing staircase type apartment house.

Patent Publication 1

Patent Publication 2002-13298

The method disclosed in Japanese Patent Publication No. 2002-13298 has a drawback in that the distance between the existing building and the new hallway must be increased to some extent in order to further extend the stairs from the landing. In addition, there was a drawback that unnecessary stairs remained after the construction.
There was an idea to remove the stairs after installing the common passage and install a common passage there, but the common passage is longer and wider than necessary, and there is a waste of work process such as installing a temporary staircase. It was.

In order to solve this problem, the invention of claim 1 is to construct a common hallway composed of a common hallway, elevator, staircase, etc. adjacent to the existing apartment house, and then existing from the top floor hallway of the common hallway building. Pass the common passage to one half of the stairs on the top floor of the building, secure the passage of residents, then remove the stairs directly below, and move to the lower floor construction in the same way, so there is no useless stairs, The distance between the existing building and the new hallway can be set freely. In addition, supporting the newly established common passage with a part of the existing stairs will improve the efficiency of construction, and will not hinder residents' traffic, shortening the construction period.

Further, the invention according to claim 2 makes it possible to effectively use the generated space for the installation of a pipe space, a small elevator, an alcove and the like after constructing the common passage, thereby eliminating the waste of space.

The present invention simplifies the steps for improving the steps to eliminate the steps, does not hinder residents' passage, shortens the construction period, and reduces construction costs. In addition, the stair space is effectively used.

FIG. 1 is a diagram in which a corridor building including a floor corridor, a staircase connecting the floors, and an elevator is newly established adjacent to an existing staircase type apartment house. Since it is constructed without connecting to existing buildings, there will be no hindrance to the residents' traffic.

FIG. 2 is a view in which a shared passage is passed from the top floor corridor of the newly-established hallway building to one half of the top floor stairs of the existing building so that residents on the top floor can use the common passage. As a result, the traffic route was secured.

FIG. 3 is a diagram in which the stairs directly under the newly-established common passage are removed. As a result, it is possible to create a state in which a shared passage can be newly passed to the lower floor. Even in this state, there is no hindrance to the residents.

On the floor directly below the top floor, 0008 and 0009 are similarly constructed. By moving to the lower floor and passing the common passage in this way, the construction progresses and residents can pass through the construction.

FIG. 4 is a plan view of each floor after constructing the common passage.

FIG. 5 is a construction completion diagram when an elevator and a staircase are installed for each existing staircase, not a new common hallway. It can be constructed in the same procedure as when installing a common hallway building.

FIG. 6 is a diagram in which a pipe space, a small elevator, and an alcove are installed in a newly created space. As a result, the space can be used effectively.

The new common passage, common corridor, and staircase structure can be constructed using reinforced concrete, PC, or steel structure.

The present invention eliminates a step in an existing stepped apartment house, so when installing a new common corridor or elevator, it can be constructed without hindrance to residents' passage, and the newly created space can be used effectively according to the situation, Has industrial applicability.

It is the top view which newly established the corridor building including each floor corridor adjacent to the existing apartment house, the stairs connecting it, and an elevator. It is a perspective view in the state where the common passage was passed from the corridor on the uppermost floor of the corridor building to one half of the uppermost staircase of the existing building. The figure on the left shows the entrance to the staircase, and the figure on the right shows a common passage on the atrium. It is the perspective view which removed the stairs just under the common passage passed by newly established. It is the top view which passed the common passage on each floor to the new common hallway. It is a top view at the time of installing an elevator and stairs for every existing stairs. It is a plan view in which a pipe space (left figure), a small elevator (center figure), and an alcove (right figure) are installed in a newly created space.

Claims (2)

A staircase improvement method in which an existing staircase-type apartment house is constructed without obstructing the passage of residents when the stairs are removed and a new hallway or elevator is installed without any steps. Effective use of the staircase to use the space created in the removed stairs for construction of pipe spaces, small elevators, alcoves, etc.
