JP-A-11-152913

  By the way, the external staircase of the conventional detached apartment house is constructed as a part of the building, so it can be changed in the installation position with respect to the building, or to another detached apartment house with a different structure. Cannot be applied.

  Therefore, the present invention can be configured so that the outer staircase of a building such as a detached apartment house can be moved as a separate structure from the building and can be easily installed at a suitable location outside the building. An object of the present invention is to provide a novel external staircase unit that can be applied to buildings having different structures, for example, new and existing buildings.

In order to achieve the above object, the invention according to claim 1 is an external staircase unit for a building which is configured separately from a building and is installed at an appropriate place outside the building,
A staircase storage box formed in a rectangular tube shape and an outer staircase incorporated in the staircase storage box, and the staircase storage box is provided with a suspension member for suspending and moving the staircase storage box. In the lower part, an installation part for fixing this on the foundation is provided.

  In order to achieve the above object, the invention according to claim 2 is the one according to claim 1, wherein the staircase storage box is formed by fixing a panel to an open outer surface of a frame that is framed in a box shape. The doorway leading to the stairs is opened.

  In order to achieve the above object, a third aspect of the present invention is characterized in that, in the first or second aspect of the present invention, the staircase storage box is composed of a commercially available freight shipping container.

  According to the first and second aspects of the invention, the outer stair unit is configured separately from the building and can be freely moved and fixed on the foundation by an appropriate transportation means. It can be installed at an appropriate place outside the building, the degree of freedom of installation of the outer stair unit for the building can be increased, and the installation cost of the outer stair unit can be reduced.

  Furthermore, the outer staircase unit can be applied to a building having a different structure, for example, a new construction or an existing construction, and its versatility is enhanced.

  According to the third aspect of the present invention, the staircase storage box can be constructed using a commercially available freight shipping container, so that the outer staircase unit can be provided at low cost.

  Embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

  This embodiment is a case where the outer stair unit 1 according to the present invention is installed in a detached apartment house as the building A.

  In this embodiment, the staircase storage box 10 constituting the main part of the outer staircase unit 1 is configured using a commercially available container for freight transportation, and includes a plurality of vertical aggregates 11a made of iron or the like. A wavy panel (corrugated panel) 12 made of an iron plate or the like is fixed to an open outer surface of a frame 11 formed by framing a horizontal aggregate 11b in a vertically long box shape.

  The staircase storage box 10 is used with its vertical direction directed up and down, and an outer staircase 23 is incorporated therein. A first-floor doorway 24 that is opened and closed by a first-floor opening / closing door 25 is opened at the lower portion of one surface of the staircase storage box 10, and a second-floor opening / closing door 27 is disposed at the upper portion of the other surface of the staircase storage box 10. The second-floor doorway 26 to be opened and closed is opened, and this second-floor doorway 26 communicates with the outer corridor Ap provided in the building A.

  A suspension member 13 having a suspension hole 14 is integrally provided at each of the upper and lower corner portions of the staircase storage box 10. The suspension hole 14 of the suspension member 13 has a mobile crane or the like (not shown). A suspension wire 15 (see FIG. 5) provided in the transportation means can be detachably engaged, and the staircase storage box 10 can be suspended.

  In addition, the said staircase storage box 10 comprised from a container can be suspended and moved even if it flips up and down by providing the suspension member 13 in each upper and lower corner part.

  As shown most clearly in FIG. 4, installation portions 17 are respectively provided in the lower part of the staircase storage box 10 adjacent to the suspension member 13. A pair of bolt holes 19 are opened in a portion of the end wall 18 of the staircase storage box 10 corresponding to the bottom wall of each installation portion 17. The outer stair unit 1 can be fixed onto the foundation B by inserting a pair of anchor bolts 20 fixed to the foundation B into the bolt holes 19 and screwing the nuts 21 into them.

  Next, with reference to FIG. 5, the case where the outer staircase unit 1 is installed in the detached apartment house which is the building A is demonstrated.

  As shown in FIG. 5 (A), the outer staircase unit 1 is carried while being suspended by appropriate transportation means such as a mobile crane, and is installed at the outer staircase installation position outside the building A.

  Next, as shown in FIG. 5 (B), one side of the outer staircase unit 1 is placed along the outer stair mounting surface of the building A, and the bolt hole 19 of the installation portion 17 of the staircase storage box 10 is formed on the foundation B. The outer stair unit 1 can be firmly fixed on the foundation B by inserting the anchor bolt 20 to be fixed and screwing the nut 21 into the anchor bolt 20. Moreover, the one side surface of the outer stair unit 1 is fixed to the outer stair mounting surface of the building A by appropriate fixing means (not shown) as necessary. The second floor entrance 26 of the outer staircase unit 1 communicates with an outer corridor Ap provided in the building A.

  The outer staircase 23 is covered with the panel 12 of the staircase storage box 10 configured using a container and is not exposed to rain and wind.

  As described above, the outer staircase unit 1 is configured separately from the building A and can be freely moved by appropriate transportation and transport means. Therefore, the outer staircase unit 1 made separately from the building A is used as the building. The outer staircase unit 1 can be installed at an appropriate place outside A, the degree of freedom in installing the outer staircase unit 1 with respect to the building A can be increased, and the installation cost of the outer staircase 23 can be reduced.

  Furthermore, the outer staircase unit 1 can be applied to a building having a different structure, for example, a new building or an existing building, and its versatility is enhanced.

  Furthermore, since the staircase storage box 10 constituting the main part of the outer staircase unit 1 can be configured using a commercially available freight shipping container, the solid outer staircase unit 1 can be provided at low cost.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to that embodiment, A various Example is possible within the scope of the present invention.

  For example, in the above-described embodiment, the case where the present invention is implemented as a building in a two-story detached apartment house has been described. However, this is applied to other two-story buildings and other buildings of three or more stories. Of course, it may be implemented.
