Description

TECHNICAL FIELD The present invention relates to a floor structure on an upper floor around a staircase.

[Conventional technology]

The conventional floor structure of the staircase will be described with reference to FIG. In the figure, 30 is a horizontal beam such as a floor beam or a girder, and 31 is a staircase provided in a staircase. Adjacent to the stairs 31, a floor panel 32 on the second floor, a floor material 33, and a stairwell 34 are provided. The floor panel 32 is a honeycomb core panel, and the outer frame is fixed to the horizontal member 30. Also,
Regarding the construction of the floor material 33, the outer frame of the floor material 33 is fixed to the horizontal member 30 and the fixing member 35 protruding from the horizontal member 30 by turning the hand from the inside, and a joist is provided in the outer frame. It is constructed by pasting a face plate. The reason why the floor material 33 cannot be formed into a panel is that the fixing member 35 does not have sufficient supporting strength to support the panel. Therefore, as described above, the outer frame, the joists, and the surface material are sequentially applied so that a large load is not applied to the fixing member 35.

[Problems to be Solved by the Invention]

Since the floor material 33 could not be formed into a panel in this way, its construction was difficult.

Therefore, an object of the present invention is to provide a floor structure with improved workability.

[Means for Solving the Problems]

The floor structure of the present invention comprises a frame structure which is surrounded by a square shape by two girders erected on the corner of the building and two floor beams erected on the indoor side of the building. In the floor structure in which a staircase is provided in the corner part, the space in the frame structure adjacent to this staircase is divided into two at the intermediate part of the adjacent surface, and the floor of the upper floor from the outside and the stairwell are respectively provided,
Two wall panels on the lower floor, which are arranged in an L-shape in the space so as to be orthogonal to the trunk and the floor beam from the intermediate portion of the adjacent surface, and are erected at the joint portion of these wall panels. And a wall panel connecting member supported by these wall panels in two directions, and a panel supporting beam installed between the wall panel connecting member and the body along the adjacent surface,
It is provided with the panel support beam having opposite sides and a floor panel adjacent to the staircase which is fixed to the floor beam facing the panel support beam.

[Action]

According to the floor structure of the present invention, the panel supporting beam is erected between the girder and the wall panel connecting member, and the wall panel connecting member is supported from two directions by the two wall panels on the lower floor, and thus the stairs are formed. It has sufficient supporting strength to support the floor panel adjacent to the room. In this way, since the strength of the panel support beam is high,
The floor part adjacent to the staircase and the stairwell may be composed of staircase adjacent floor panels. Further, since the floor portion is panelized in this way, the construction can be easily performed by fixing the outer frame of the floor panel adjacent to the staircase to the panel support beam and the floor beam.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 shows a plan view of the second floor of the building. This floor structure is composed of two barrels 1 installed at the corners of the building.
0, 11 and two floor beams 12, which are erected on the indoor side of the building,
A frame structure surrounded by a square 13 is provided, and a staircase 15 is provided at a corner of the building. A space inside the frame structure adjacent to the staircase 15 is divided into two at an intermediate portion of the adjacent surface, and the outside To the floor of the upper floor, and the floor structure provided with the stairwell 18 respectively, the two floors of the lower floor arranged in an L shape in the space so as to be orthogonal to the barrel 10 and the floor beam 12 from the intermediate portion of the adjacent surface. Wall panels 27 and 28, a wall panel connecting member 26 that is erected at the joint between the wall panels 27 and 28 and is supported by the wall panels 27 and 28 from two directions, and a wall along the adjacent surface. Panel connecting member 2
6, a panel support beam 16 installed between 6 and the body insert 10,
It is provided with a panel support beam 16 on opposite sides and a stair room adjacent floor panel 17 fixed to the floor beam 12 facing the panel support beam 16, respectively. The staircase 15 is a space in which a U-shaped staircase is installed. 14 is a horizontal member 11, 12,
It is a floor panel on the second floor fixed to No. 13, and has a honeycomb core inside the outer frame and a surface plate attached.

Next, a mounting structure of the floor panel 17 adjacent to the staircase will be described. FIG. 2 is an enlarged view of portion II of FIG.
A sectional view taken along the line III-III of the figure is shown in FIG. The floor panel 17 adjacent to the staircase is one in which a honeycomb core 21 is provided inside an outer groove-shaped outer frame 20, and a surface material 22 is attached to the surface thereof.
Fixed hardware 23 having a horizontal cross section is welded to the four corners of 0. The panel support beam 16 is formed in a lateral groove shape,
One end is fixed to the barrel 10 by a fixing portion 24 such as a shear pin (one end of a screw rod formed into a hexagonal rod). In the floor panel 17 adjacent to the staircase, the fixing metal piece 23 at one corner is fixed to the panel support beam 16 by a fixing tool 25.

Further, FIG. 4 is an enlarged view of the IV portion of FIG. 1, and the VV sectional view and the VI-VI sectional view of FIG. 4 are shown in FIG. 5 and FIG. In the figure, reference numeral 26 is a groove-shaped wall panel connecting member, which is erected with its lower end fixed to the upper portions of the side frames of the first floor wall panels 27 and 28. Wall panel connecting member 2
An end portion of the panel support beam 16 is fixed to the upper end of 6 by a fixing tool 29. In addition, the fixing hardware 23 at one corner of the floor panel 17 adjacent to the staircase is fixed to the panel support beam 16 by the fastener 25.
Fixed to.

In addition, as shown in FIG. 1, the fixing hardware of the other corners of the floor panel 17 adjacent to the staircase is also fixed to the floor beam 12.

According to the floor structure thus configured, the panel support beam 1
6 is installed between the body insert 10 and the wall panel connecting member 26, and the wall panel connecting member 26 is supported by two wall panels on the lower floor from two directions.
It has a supporting strength sufficient to support 7. in this way,
Since the panel support beam 16 has high strength, the floor portion adjacent to the staircase 15 and the stairwell 18 can be configured by the staircase adjacent floor panel 17. Further, since the floor portion is panelized in this way, the construction can be easily performed by fixing the outer frame of the floor panel 17 adjacent to the staircase to the panel support beam 16 and the floor beam 12.

〔The invention's effect〕

According to the floor structure of the present invention, the panel supporting beam is erected between the girder and the wall panel connecting member, and the wall panel connecting member is supported from two directions by the two wall panels on the lower floor, and thus the stairs are formed. It has sufficient supporting strength to support the floor panel adjacent to the room. In this way, since the strength of the panel support beam is high,
The floor part adjacent to the staircase and the stairwell may be composed of staircase adjacent floor panels. Further, since the floor portion is panelized in this way, the outer frame of the floor panel adjacent to the staircase can be easily installed by fixing it to the panel support beam and the floor beam.
