Description

[Detailed description of the invention] [Technical field] This invention relates to a support structure for a stair landing that is applied to prefabricated houses and the like.

[Background technology]

Conventionally, a carpenter assembled a wooden pedestal, fixed a stair landing member on top of the pedestal, and then attached the main body of the staircase. As a result, installation of the stair landing became complicated and the structure became complicated.

[Purpose of invention]

The object of this invention is to provide a support structure for a stair landing that allows the stair landing to be easily installed.

[Disclosure of invention]

The stair landing support structure of this invention has one end connected to a support beam fixture fixed to a horizontal frame member of a wall panel to provide a support beam, and a landing member is placed on this support beam.

According to the configuration of this invention, there are the following effects.
In other words, the work of joining one end of the support beam to the support beam fixture fixed to the horizontal frame material of the wall panel, and the work of placing the landing member on the support beam are sufficient, making it easy to install the stair landing. .

Embodiment An embodiment of this invention will be described based on FIGS. 1 to 5. As shown in FIG. 2, the staircase of this embodiment includes a staircase landing member 62 provided along the exterior wall panel 10 and partition wall panel 11 of the building, and a staircase 14 extending upward from the landing member 62.
It has a folding staircase structure with an entrance 16 located below.

FIG. 4 is a plan view of the location where the stairs are installed. In the figure, 20 and 22 are cloth foundations. Also, 2
Reference numerals 4 and 26 designate groove-shaped wall-mounting hardware erected on the cloth foundation 20. Between the wall mounting hardware 24, 26, the panel frame is bolted to the wall mounting hardware 24, 26,
Partition wall panel 11 (see Figures 1 and 5)
will be installed. 28, the panel frame 30 is attached to the cloth foundation 2
This is a large floor panel on the first floor that is bolted to L-shaped base metal fittings 34 fixed at the top of each of Nos. 0, 22, and 32 (see Figure 1). Also, 10,
Reference numeral 38 is an outer wall panel provided by bolting a panel frame to the wall mounting hardware 24, and 40 and 42 are outer wall panels constituting the entrance. Exterior wall panel 4
A pillar 44 is erected between 0 and 42, and each panel frame is joined to the pillar 44. Also, 4
Reference numerals 6 and 48 indicate pillars whose upper ends reach the same height as the upper end surface of the outer wall panel 40 and are joined to the upper surface of the floor panel 28 to stand upright. Between the pillars 46 and 48, an outward-facing channel steel receiving beam 50 is fixed with bolts and is installed with the upper surface of the pillars 46 and 48 at the same height. Furthermore, between the pillars 44 and 48, a support beam 52, also made of outward-facing channel steel, is fixed with bolts and constructed at the same height as the support beam 50. Further, between the upper frame member 41 serving as the horizontal frame member of the outer wall panel 40 and the pillar 46, a support beam 54 made of inward channel steel is installed at the same height as the support beams 50 and 52. Beam support 5
4 is connected to the pillar 46 by bolting. On the other hand, the connection to the outer wall panel 40 is made by the third
Proceed as shown in the figure. That is, as shown in the figure, the flange piece 4 of the upper frame 41 of the outer wall panel 40
3, a support beam fixture 53 is fixedly installed. The support beam fixture 53 is a piece of analytically bent hardware, and is fixed to the flange piece 42 by fastening both edges to the flange piece 42 with fasteners 55 and 57. Further, two bolt insertion holes 61 are provided in the central protruding portion 59, and the protruding portion 59 is provided with two bolt insertion holes 61.
A nut (not shown) is welded to the inner surface of 9. On the other hand, the end plate 58 of the support beam 54 has
A bolt insertion hole 60 is provided. Then, bolts (not shown) are inserted into the bolt insertion holes 60 and 61 and fastened to nuts (not shown).

In this way, the stair installation location is constructed. Next, the stairs are installed as shown in FIG. In the figure, the landing member 62 has an edge portion attached to each support beam 50, 5.
2 and 54 and the upper end surfaces of the outer wall panel 40. A staircase 64 is installed extending downward from this landing member 62. The space formed between the bottom surface of the stairs 64 and the floor panel 28 is
It is used as a stairwell for storage, etc. Further, a staircase 66 is provided extending upward from the landing member 62 and perpendicularly to the staircase 64. Also, 6
7 is a handrail. In addition, FIG. 1 is a cross-sectional view taken from the side of FIG. 5, and in the same figure, 68 is a floor panel on the second floor.

According to the stair landing support structure configured in this way, the landing member 62 is placed on the support beam 54, and the landing member 62 is placed on the support beam 54.
Since it has a structure in which one end is bolted to the support beam fixture 53 fixed to the upper frame member 41 of the outer wall panel 40, assembly is easy. Therefore, the landing member 62, which is a heavy object, can be temporarily fixed, and the number of man-hours and labor required for carpentry work can be reduced.

Furthermore, since one end of the support beam 54 is connected to the support beam fixture 53 fixed to the upper frame material 41 of the outer wall panel 40, a pillar or the like for receiving the support beam 54 is not required.
The number of parts can be reduced.

Moreover, since the support beam 54 is fixed to the upper frame material 41 of the outer wall panel 40 via the support beam fixture 53, even if a load is applied to the support beam 54, the upper frame material 41 will not be damaged such as deformation. Hard to occur.

Note that the receiving beam 54 may be made of outward channel steel.

Furthermore, the support beam 54 of this embodiment has one end joined to the upper frame material 41 of the outer wall panel 40 that constitutes the entrance, but it also connects to the upper frame material of other outer wall panels and partition wall panels and laterally. It may be joined to an extending middle crosspiece or the like.

In addition, in this embodiment, one end of the support beam 54 is connected to the support beam fixture 53 of the outer wall panel 40, and the other end is connected to the pillar 46, but both ends of the support beam 54 are fixed to the horizontal frame material of the wall panel. It may be joined to the support beam fixture.

[Effect of idea]

According to this invention, the stair landing can be easily attached because the support beam is joined to the support beam attachment tool connected to the horizontal frame material of the wall panel, and the landing member is placed on the support beam.
