Description

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

[Background technology]

Conventionally, a carpenter assembles a wooden frame, fixes a stair landing member onto the frame, and attaches the main body of the staircase. However, in industrialized houses using the panel construction method that uses large floor panels on the first floor, the first floor panels are installed at the time of building the building, so this large first floor floor panel can be used effectively and the stairs can also be installed at the time of building the building. It is hoped that the number of man-hours and labor required for carpentry work will be reduced. To this end, it is necessary to make the installation of stair landings easy.

[Purpose of invention]

The purpose of this invention is to provide a stair landing mounting structure that can be easily installed when constructing a building.

[Disclosure of invention]

The stair landing mounting structure of this invention is provided with a landing support frame from which a pillar is suspended from one end, and the other end of this landing support frame is joined to the horizontal frame material of the external wall panel.
The lower end of the column is joined to the upper surface of the floor panel, and the landing member is mounted on the landing support frame.

According to this configuration, construction can be easily carried out because only the work of joining the end portion of the landing support frame to the horizontal frame member of the outer wall panel and the work of mounting the landing member on the landing support frame are required.

An embodiment of this invention is shown in FIGS. 1 to 4. In the figure, 1 is a landing support frame;
A landing member 2 is mounted on a rectangular frame formed by a frame member 1a of L-shaped steel. The landing member 2 becomes a part of a U-shaped staircase. Landing support frame 1
At one end, two pillars 3 are fixed together by welding or the like and hang down, and at the other end are horizontal frame members 5 of the outer wall panel 4.
It is joined to. The horizontal frame member 5 consists of a downward channel member, and a screw hole 6a (Fig. 4) is formed by a welding nut 6.
is formed. Landing support frame 1 and horizontal frame material 5
The connection is made by screwing bolts 7 inserted through holes in the frame material 1a of the landing support frame 1 into screw holes 6a in the horizontal frame material 5. The column 3 has a leg member 10 whose height can be freely adjusted with a screw member 9 attached to the lower end thereof, and the leg member 10 is placed on the upper surface of a floor panel 11 and fixed to the floor panel 11 with a nail inserted into a mounting hole 12. Ru.

During construction, after installing the floor panel 11 and wall panel 4 at the time of construction, the landing support frame 1 is joined to the horizontal frame material 5 of the wall panel 4, and the foot member 10 is
After that, the landing member 2 is placed on the landing support frame 1 and installed. The main fixing will be done later during carpentry work.

In this way, the landing support frame 1 with columns 3
The landing member 2 is placed on the board, and the landing support frame 1 is bolted to the horizontal frame member 5 of the outer wall panel 4.
Since the structure is such that the lower end of the pillar 3 is joined to the floor panel 11, assembly is easy. Therefore, it is possible to temporarily install the staircase assembly during building construction. and,
Since the landing member 2, which is a heavy object, is temporarily fixed at the time of construction, the number of man-hours and labor required for carpentry work can be reduced.

5 to 8 show other embodiments. In this example, the landing support frame 14 is made of one channel steel, and three of them are provided in parallel. A pillar 15 is integrally suspended from one end of each landing support frame 14. The leg member 16 has a pillar fitting member 16a that is fitted into the square pipe-shaped pillar 15 and protrudes from the upper surface thereof.
In addition, a mounting hole 17 is provided. Pillar fitting member 16a
and a bolt 18 aligned with each other at the lower end of the column 15,
19 is provided.

During construction, first the leg member 16 is bolted to the lower end of the pillar 15. Welding may also be used. Next, the horizontal frame member 5 of the outer wall panel 4 is positioned, bolt holes are opened, and the landing support frame 14 is fixed with bolts. After this, the landing member 2 is attached to the landing support frame 14.
Install on top. The main fixing will be done later during carpentry work. The foot members 16 are inserted into the mounting holes 17 when fully fixed.
It is fixed to the floor panel 11 with nails inserted through it. The rest is the same as the first embodiment.

9 and 10 show examples of proposed stair landing mounting structures that can achieve the same purpose as this invention. In this example, a pedestal 25 is constructed of three portal frames 21, two joint beams 22, and two types of foot members 23, 24, and a stair member 2 is placed on this pedestal 25.
is to be installed. The gate-shaped frame 21 consists of pillars 26 made of square pipes and horizontal members 27 made of channel steel. 28 is a bolt hole. One foot member 23
is attached to a column 26 along the outer wall, and the other leg member 24 is attached to another column 26. Both leg members 23 and 24 have pillar fitting protrusions 23a and 24a that fit into the pillar 26, and are provided with bolt holes 29 for joining the pillars and attachment holes 30 for fixing to the floor. The joining beam 22 is made of downward channel steel and has end plates having bolt holes 31 at both ends.

Explain the construction procedure. First, the leg members 23 and 24
is bolted to the lower end of the column 26 of the portal frame 21. Next, the joint beam 22 is bolted to the bolt hole 28 of the portal frame 21, and thereby the frame 2
5 is completed. Thereafter, the frame 25 is positioned on the outer wall (not shown), and the leg members 23 on the outer wall side are fixed to the floor panel with nails. Next, the landing member 2 is mounted on the pedestal 25. The main fixing will be done by carpenter. The rest is the same as the first embodiment.

[Effect of idea]

The stair landing mounting structure of this invention has the advantage that it can be easily installed at the time of construction.
