Abstract

(57) [Summary] [Purpose] To provide a staircase landing support structure that can effectively use the space below the stairway landing. [Structure] A staircase landing 2 is arranged between a pair of juxtaposed beams 1, and the staircase landing 2 is supported by lateral pieces 4 of a plurality of L-shaped members 3 whose upper ends are attached to the beam 1. [Effect] It is not necessary to provide a pedestal or the like below the staircase landing 2, and the space below the stairway landing 2 can be used as a stairway opening or a staircase room.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stair landing support structure for providing a stair landing in a building.

[0002]

[Prior Art]

 In the past, when building a staircase landing in a building, the staircase landing was supported from below by assembling a pedestal on the floor.

[0003]

[Problems to be solved by the device]

 However, because of the pedestal, the space below the staircase landing could not be used and was wasted. The purpose of this invention is to provide a staircase landing support structure that can effectively use the space below the staircase landing.

[0004]

[Means for Solving the Problems]

 In the staircase landing support structure of the present invention, the stairway landing is arranged between a pair of beams arranged in parallel, and the stairway landing is supported by a horizontal piece of a plurality of L-shaped members whose upper ends are attached to the beams.

[0005]

[Action]

 According to the staircase landing support structure of the present invention, the stairway landing is arranged between a pair of juxtaposed beams, and the staircase landing is supported by the lateral pieces of the plurality of L-shaped members whose upper ends are attached to the beams. There is no need for a stand or the like.

[0006]

【Example】

 The staircase landing support structure of one embodiment of the present invention has a plurality of L-shaped members in which a stairway landing 2 is arranged between a pair of beams 1 arranged in parallel as shown in FIG. The horizontal piece 4 of 3 supports the staircase landing 2. The beam 1 is composed of a pair of grooved steels 1a in which flanges are opposed to each other in the vertical direction and arranged at intervals, and a plurality of lattice bars 1b and 1c spanned between the grooved steels 1a. The staircase landing 2 includes a step-like main body 2a having a pair of treads 2c and 2d, and a frame 2b that reinforces the bottom of the main body 2a. As shown in FIG. 5, the frame body 2b is a frame structure in which three pieces of wood 22 are bridged between a pair of channel steels 21. As shown in FIG. 2, the L-shaped member 3 is a combination of a pair of metal fittings 3 a and a pair of metal fittings 3 b, and is arranged near each corner of the staircase landing 2.

As shown in FIG. 4, the metal fitting 3a has a fixing piece 6a at its upper end and a horizontal piece 4 at its lower end. As shown in FIG. 3, the fixing piece 6a is provided with a pair of bolt insertion holes 6c, and the bolt 12 inserted into the bolt insertion hole 6c and the bolt insertion hole 1a formed at the bottom of the beam 1 is attached to the nut 13. It is fixed to the lower surface of the beam 1 by tightening with. The horizontal piece 4 has a bolt insertion hole 4a formed therein, and is fixed to the frame body 2b by screwing the wood screw 14 inserted into the bolt insertion hole 4a into the lower surface of the wood 22. As shown in FIG. 4, the metal fitting 3b has a fixed piece 6b having a longer overall length than the fixed piece 6a. Other than this, it is the same as the metal fitting 3a. 2 and 3, reference numeral 11 indicates a wall panel.

As described above, since the staircase landing 2 is fixed to the beam 1 via the L-shaped member 3, it is not necessary to provide a stand or the like (not shown) below the stairway landing 2. Therefore, the space below the staircase landing 2 can be used as a staircase opening or a staircase room.

[0009]

[Effect of the device]

 According to the staircase landing support structure of the present invention, the staircase landing is arranged between a pair of beams arranged in parallel, and the staircase landing is supported by the horizontal pieces of the L-shaped members whose upper ends are attached to the beams. Therefore, it is not necessary to install a stand or the like below the staircase landing. Therefore, the space below the staircase can be used as a staircase opening or a staircase.
