Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improvement of a unit stair mounting structure.

[0002]

[Prior Art]

 For example, as a mounting structure of the unit stairs 50 to be mounted on the stairway corridor side portion 82 on the second floor from the ground on the first floor of the prefabricated house 80 shown in FIG. 3, the structure shown in FIG. 4 is conventionally known.

In this mounting structure, columns 83 and short columns 85 are arranged at both ends of a stair girder 81 on the second floor at intervals corresponding to the spacing between the sasara girders 52 and 54 of the unit stairs 50. A pair of receivers 84 and 86 are attached to the pillars 83 and the short pillars 85 by welding or the like, the sasara girders 52 and 54 of the unit stairs 50 are joined to the above-mentioned brackets 84 and 86, and the sasara girders are attached by bolts and nuts not shown. 52 is fixed to the receiving member 84, and the sasara girder 54 is fixed to the receiving member 86.

[0004]

[Problems to be solved by the device]

 However, in the case of the above-described conventional mounting structure, when the sasara girders 52, 54 of the unit stairs 50 are distorted due to manufacturing errors, impact during transportation, etc., the sasara girders 52, 54 and the supports 84, 86 It is not easy to align them, and especially the receiving members 84 and 86 do not have the horizontal and height positioning functions of the sasara girders 52 and 54. Therefore, the unit stairs 50 can be swiftly moved to the pillars 83 on the second floor stairway corridor side. However, there was a problem that it could not be attached to the short column 85.

Therefore, an object of the present invention is to provide a unit staircase mounting structure capable of easily and quickly mounting a unit staircase.

[0006]

Means for Solving the Problems The present invention provides a unit staircase mounting structure for mounting a pair of sasara girders of a unit stairway to a stairway corridor side portion provided in a building, wherein one sasara girder is mounted in the stairway corridor side portion. L-shaped first receiving member consisting of a horizontal regulating piece and a vertical regulating piece provided in a portion, and a flat long hole for inserting a bolt provided in a mounting portion of the other sasara girder in the stairway corridor side portion is bored. And a second receiving member provided.

[0007]

[Action]

 According to the unit staircase mounting structure configured as described above, the L-shaped first receiving member including the horizontal regulating piece and the vertical regulating piece is provided at the mounting portion of one sasara girder in the stairway corridor side portion, and the stairway corridor side portion is provided. Since the second receiving member, which is flat and has a long hole for inserting a bolt, is provided at the mounting portion of the other girder girder, the horizontal and height alignment of one girder girder of the unit stairs is performed. , The horizontal regulation piece and the vertical regulation piece of the first receiving member, and the change in the position of the other sasara girder due to this alignment is absorbed by the elongated hole for inserting the bolt of the second receiving member.

[0008]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail.

FIG. 1 and FIG. 2 show an example of a unit staircase mounting structure of this embodiment. The unit staircase mounting structure of the present embodiment has one sasara girder 12 for one of the pillars 2 and the short pillars 4 of the stairway on the second floor as the stairway corridor side part to which the pair of sasara girders 12, 14 of the unit staircase 10 are mounted. The L-shaped first receiving member 26 including the horizontal regulation piece 22 and the vertical regulation piece 24 is provided on the support column 2 which is the mounting portion of the above, and flat bolts are inserted into the short support column 4 which is the mounting portion of the other sasara girder 14. A second receiving member 28 having a long hole 30 for general use is provided.

A stair girder 16 is arranged between the pillar 2 and the short pillar 4.

The lower pieces 12a and 14a of the sasara girders 12 and 14 are provided with bolt insertion holes 18, respectively. The horizontal regulation piece 22 is also provided with a bolt insertion hole 20.

The first receiving member 26 and the second receiving member 28 are attached to the stair girder 16 by welding or bolting.

According to the unit staircase mounting structure described above, the horizontal and vertical alignment of one of the sasara girders 12 of the unit staircase 10 can be performed in the horizontal direction and the height direction 24 of the first receiving member 26. Then, the sasara girder 12 is brought into close contact with the horizontal regulation piece 22 and the vertical regulation piece 24 as shown in FIG.

Further, as the position of the other sasara girder 14 changes due to the horizontal alignment of the one sasara girder 12, the position of the bolt insertion hole 18 provided in the lower piece 14a of the sasara girder 14 also becomes horizontal. Although it changes depending on the direction, the second receiving member 28 is provided with the long hole 30, so that the other sasara girder 14 can be more freely positioned.

After the above-mentioned alignment is completed, the bolt 34 is inserted into the bolt insertion hole 18 provided in the lower piece 12a of the one sasara girder 12 and the bolt insertion hole 20 provided in the horizontal regulation piece 22. Then, by tightening with the nut 32, the sasara girder 12 can be fixed to the first receiving member 26. Further, the bolt 34 is inserted into the bolt insertion hole 18 and the long hole 30 provided in the lower piece 14a of the other sasara girder 14, and the nut 32 is tightened to fix the sasara girder 14 to the second receiving member 28. can do.

As described above, according to the unit staircase mounting structure of this embodiment, the horizontal alignment and the heightwise alignment of one of the sasara girders 12 of the unit staircase 10 are regulated horizontally by the first receiving member 26. The horizontal position change of the other sasara girder 14 due to this alignment can be dealt with by the long hole 30 for bolt insertion of the second receiving member 28, whereby the crane etc. It becomes possible to easily and quickly mount the unit stairs 10 by using, and the construction period can be shortened.

The present invention is not limited to the above-mentioned embodiments, and various modifications can be made within the scope of the invention.

For example, in the above embodiment, the first receiving member 26 is attached to the column 2, and the second receiving member 28 is attached to the short column 4. However, the present invention is not limited to this, and it may be attached to the stair beam 16. It is also possible to do so.

[0019]

[Effect of the device]

 As described above in detail, according to the present invention, it is possible to easily and quickly install the unit stairs to the stairway corridor side portion, and the unit staircase mounting that can shorten the construction period can be achieved. A structure can be provided.
