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 joined to the horizontal frame member of the wall panel to provide a support beam, and the landing member is placed on the support beam.

According to the configuration of this invention, there are the following effects.
That is, the work of joining one end of the support beam to the horizontal frame material of the wall panel and the work of mounting the landing member on the support beam are sufficient, and the installation of the stair landing can be easily performed.

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 so that the upper ends of the pillars 46 and 48 are at the same height. Furthermore, between the pillars 44 and 48, a support beam 52, which is also made of outward facing channel steel, is fixed with bolts and installed 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 outward 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, joining to the outer wall panel 40 is performed as shown in FIG. That is, as shown in the figure, the flange piece 43 of the upper frame 41 of the outer wall panel 40
A bolt insertion hole 56 is provided in the upper frame, and a nut (not shown) is welded to the inside of the upper frame. Further, the end plate 58 of the support beam 54 is provided with a bolt insertion hole 60. Then, a bolt (not shown) is inserted into the bolt insertion hole 60, 56 and fastened to a nut (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, 67
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 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.

Also, connect one end of the support beam 54 directly to the outer wall panel 40.
Since it is joined to the upper frame member 41, a pillar or the like for receiving the support beam 54 is not required, and the number of members can be reduced.

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

Further, in this embodiment, one end of the support beam 54 is connected to the outer wall panel 40 and the other end is connected to the pillar 46, but the support beam 54
Both ends of 4 may be joined to the horizontal frame material of the wall panel.

6 and 7 show examples of other proposed support structures for stair landings. In Figure 6, 70 and 74 are cloth foundations, and 72 is cloth foundation 71 (see Figure 8).
It is a base metal fitting of upward channel steel fixedly installed on the top, and 76 is a large drawer. These, cloth foundation 70,7
A large first-floor floor panel 78 is installed in the area surrounded by 4, base hardware 72, and large drawer 76. The floor panel 78 has a panel frame 8 provided around it.
0 is fixedly installed by bolting to the base hardware 72 and each base hardware 82, 84, 86, 88 formed of L-shaped steel. Also, 90,92,94,9
Reference numerals 6 denote channel steel columns that are erected on the upper surface of the floor panel 78, respectively. FIG. 10 shows how the pillar 96 and the floor panel are joined. In the figure, the surface plate 98 is cut out at the location where the pillar 96 of the floor panel 78 is installed, and the flange piece 102 of the panel frame 80
Two bolt insertion holes 104 are provided in the. Note that a nut (not shown) is welded to the inner surface of the flange piece 102 of the bolt insertion hole 104 in advance. On the other hand, the end plate 1 at the lower end of the column 96
06 is also provided with two bolt insertion holes 108, and the lower ends of the pillars 96 are fitted into the notches 100 of the surface plate 98. Then, a bolt (not shown) is inserted into each bolt insertion hole 108, 104 and fastened to a nut (not shown). In this way, the pillar 96 is erected on the floor panel 78. In addition, other pillars 90, 9
2 and 94 are similarly fixed to the floor panel 78.
In addition, between the upper ends of each column 90, 92, 94, 96, there are provided support beams 110, 112, 11 of outward channel steel.
4,116 are installed with bolts.

In FIG. 7, wall panels are installed on the cloth foundation shown in FIG. 6, and stairs are attached. That is, the panel frame is bolted to wall mounting hardware 118, 120 made of outward-facing channel steel fixed to the upper surface of the cloth foundation 70, and the outer wall panel 122 is erected.
Moreover, 123 is a partition wall panel. moreover,
A landing member 124 is installed with its side edge placed on each receiving beam 110, 112, 114, and 116. A crosspiece 126 is provided inside the landing member 124 (see FIG. 8). 128 is a staircase extending downward from the landing member 124, and 130 is a staircase extending downward from the landing member 124.
