Description

[Detailed description of the invention] (Industrial application field) This invention relates to outdoor stairs for buildings such as apartments and condominiums, and its purpose is to provide an outdoor staircase that can be installed with simple construction without wasting land.

(Prior Art and its Problems) Conventionally, buildings such as apartments and condominiums have been built side by side with small gaps in between in order to make effective use of the site area.

However, since the outdoor stairs of such buildings were supported on one side by the outer wall of the building and on the other side by supports installed separately on the ground, the construction space and area required for construction were relatively large. When installing outdoor stairs, there is no choice but to avoid small gaps between buildings and install them so that they extend over the exterior wall of the building facing a large site.In addition to the construction effort of erecting supports, it also takes up a considerable amount of land. amount required.

(Means for Solving the Problem) In this invention, an outdoor staircase is installed between opposing side walls of buildings installed side by side, and the lower staircase is installed at an upward slope from the floor surface of the floor between the side walls. and an upper staircase installed at a downward slope from the upper floor surface constructed between the side walls, are connected in a folded manner via a landing base frame, and the middle parts of both sides of this landing base frame are connected to the side wall and the front wall. The landing base frame is installed between the side walls, and a part of the landing base frame protrudes like an eave from between the side walls to the front of the front wall. All of the above problems are solved by providing an outdoor staircase in which both ends of a U-shaped frame attached to a vertical frame erected on the periphery of a protrusion are connected to each of the pillars.

(Example) An embodiment of this invention will be described based on the drawings.

1 to 4 are views for explaining an outdoor staircase according to an embodiment of this invention.

A in the figure indicates an outdoor staircase, and this outdoor staircase A is arranged between opposing side walls 2 of buildings 1 installed in parallel, and includes a lower staircase 13, an upper staircase 15,
It consists of 3 landings.

The lower staircase 13 is installed with an upward slope from the lower floor surface 12 between the side walls 2.

The upper staircase 15 is installed with a downward slope from the upper floor 14 constructed between the side walls 2.

The lower staircase 13 and the upper staircase 15 are connected via the landing base frame 7 in a folded manner. The landing base frame 7 is composed of a front crosspiece 7a, a side crosspiece 7b, a base crosspiece 7c, and an auxiliary crosspiece 7d, and a landing 3 is formed by attaching landing flooring material (not shown).

The middle parts of both side beams 7b, 7b of this landing base frame 7 are attached to each column 5 of the ridge of the side wall 2 and front wall 4, and when this landing base frame 7 is constructed between the side walls 2, A part of this landing base frame 7 is projected from between the side walls 2 to the front of the front wall 4 like an eave.

A U-shaped frame 10 consisting of a front bar 10a and a side bar 10b is attached to a pair of vertical bars 9, 9 erected on the periphery of a protruding portion of a landing base frame 7. Furthermore, the side beams 10b of the U-shaped frame 10 are connected to each of the pillars 5, respectively. A handrail panel 11 is attached to the vertical beam 9 and the U-shaped frame 10 to form a handrail of the landing.

The configuration of the embodiment of this invention is as described above.

Next, the construction method will be explained.

First, the pillar 5 on the ridge between the side wall 2 and front wall 4 of the building 1
The landing base frame 7 is constructed between the side walls 2 by fixing the crosspieces 7b, 7b on both sides of the landing base frame 7, and
An upper floor 14 is constructed between the side walls 2.

Next, a lower staircase 13 is constructed between the lower floor surface 12 and the landing base frame 7, and an upper staircase 15 is constructed between the landing base frame 7 and the upper floor 14.

(Effect of the invention) This invention is an outdoor staircase installed between opposing side walls of buildings installed side by side. An upper staircase installed at a downward slope from the upper floor surface is connected in a folded manner via a landing base frame, and the middle part of both sides of this landing base frame is connected to the ridge between the side wall and the front wall. Attached to each column, this landing base frame is constructed between the side walls, and a part of this landing base frame protrudes from between the side walls to the front wall forward like an eave, and the periphery of the protruding part of this landing base frame Since the outdoor staircase is formed by connecting the ends of the U-shaped frame to the pillars, which are attached to the vertical beams erected in the staircase, the following effects can be achieved.

The existing pillars of the building are used to support the landing and, by extension, the entire outdoor staircase, so compared to conventional methods that require the installation of separate pillars, construction is less labor-intensive and easier to construct. It also requires less area.

Moreover, because the stairs can be installed between the side walls of a building, the site area can be used effectively, unlike conventional stairs that are installed over a large site.

Furthermore, a part of the landing protrudes forward from the front wall of the building in the form of an eave, but this protruding part is not included in the building area, and can change the exterior appearance by creating a balcony style.

Moreover, since this outdoor staircase is connected to the lower floor surface, the upper floor surface, and the pillars of the building, it is supported robustly.
