Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a floor structure applied to a second floor floor of a residence, etc.

[Background technology]

Conventionally, so-called skip floors, in which floors on the same floor have different heights, have been used to create variety in the interior space.

However, when building a floor structure with such height differences using floor panels, if both the high floor panels and low floor panels placed on both sides of the floor joist are attached to the sides of the floor joist, the height of the floor joist will increase. You will need something with high quality. Therefore, a floor beam with a cross-sectional shape that is larger than the required strength is used, which is uneconomical.

[Purpose of the invention]

An object of the present invention is to provide a floor structure that can provide a floor surface with height differences without using floor beams with a high cross-sectional shape.

[Disclosure of the invention]

The floor structure of the present invention includes a floor beam provided with a raised panel mounting fixture on the upper surface, a low floor panel placed on one side of the floor beam and joined to a side surface of the floor beam, and a low floor panel provided on the other side of the floor beam. The high floor panel is arranged at a higher top surface position than the low floor panel and is connected to the raised floor panel fixture.

According to the configuration of this invention, the raised floor panel is joined to the raised floor panel fixture provided on the upper surface of the floor beam, so the raised floor panel can be installed without making the floor beam have a high cross-sectional shape. Ru. Therefore, the cost of floor beams is low. Since the raised floor panel fixtures only need to be installed in a part of the longitudinal direction, compared to the case where the entire floor beam has a large cross-sectional shape,
Material costs are low.

Embodiment An embodiment of the present invention will be explained based on FIG. This floor structure consists of a floor beam 2 with a raised panel fixture 1 on its upper surface, a low floor panel 3 placed on one side of the floor beam 2 and joined to the side surface of the floor beam 2, and a low floor panel 3 on the other side of the floor beam 2. and a raised floor panel 4 whose upper surface is arranged higher than the low floor panel 3 and joined to the raised floor panel fixture 1.

The floor beam 2 is made of I-beam steel. The floor beam 2 and the low floor panel 3 are joined via a low floor panel fixture 5.

The low-floor panel fixture 5 consists of a groove-shaped metal piece welded to the web side surface of the floor beam 2, and connects the low-floor panel 3 with bolts and nuts.

The raised floor panel fixture 1 is a groove-shaped metal member provided in a part of the longitudinal direction of the floor beam 2, and is welded to the upper surface of the floor beam 2.

The raised floor panel 4 is joined to the raised floor panel fixture 1 with bolts and nuts. Reference numeral 6 denotes a wooden edge member, which is provided along the entire length of the raised floor panel 4 so as to have the same upper surface height as the raised floor panel 4. A carpet 7 is spread over the raised floor panel 4 and the edge member 6.

The other sides of the high-floor panel 4 and the low-floor panel 3 are bolted to the barrel 8. The barrel difference 8 is made of channel steel or the like. Torso difference 8
The second floor exterior wall panel 9 and the first floor exterior wall panel 10 are arranged above and below. 11 is the ceiling surface of the first floor.

According to this configuration, since the floor surface heights of the high floor panel 4 and the low floor panel 3 are different, the indoor space can be varied. In addition, since the raised floor panel 4 is joined to the raised floor panel fixture 1 provided on the upper surface of the floor beam 2, the raised floor panel 4 can be installed without having to make the floor beam 2 have a high cross-sectional shape. . Therefore, the cost of the floor beam 2 is low. Since the high beam panel fixture 1 only needs to be provided at a portion in the longitudinal direction, the material cost is lower than when the entire floor beam 2 has a large cross-sectional shape.

FIGS. 2 and 3 show other embodiments. This example shows an L-shaped low floor panel fixture 5 welded to the bottom flange of the floor beam 2.
A low floor panel 3 is bolted to the bottom panel . Floor beam 2
In this case, the end plate 12 is welded and a through hole 13 is formed in the web. The rest is the same as the first embodiment.

FIG. 4 shows yet another embodiment. In this example, the high floor panel 4' and the low floor panel 3' are formed sufficiently thicker than usual.

For example, the thickness is 1151 or more. High floor panel 4'
and the side edge of the low floor panel 3' opposite the floor beam 2 is bolted to a floor panel fixture 14,15. Floor panel fixings 14.15 are used for high floor panel 4' and low floor panel 3.
', or even in the middle. The floor panel fixtures 14 and 15 are made of a steel material with an L-shaped horizontal cross section and a plurality of reinforcing plates 16 welded to the steel material. The floor panel fixtures 14 and 15 are fixed to a wall panel or the like on the lower floor. The high floor panel 4' and the low floor panel 3' are
A floor material 18 and a lower surface material 1 are attached to a panel frame 17 made of channel steel.
9 and a honeycomb core 20 is placed inside.

In this configuration, the high floor panel 4' and the low floor panel 3'
Since the thickness of the plate is increased, it can support horizontal force.

Therefore, it becomes unnecessary to provide a trunk difference around the circumference. That is, in the past, in order to support the horizontal force, a truss was provided around the entire perimeter of the building, but in this embodiment, the panel frame 17
can also serve as the function of a conventional torso difference, and the torso difference can be omitted.

In addition, the thickness of the high floor panel 4' and the low floor panel 3' is thicker, and the amount of overlap increases, so vibration resistance and sound insulation properties are improved.
It also has stronger rigidity and improved deflection performance.

FIGS. 5(A) to 5(E) show examples of the second floor floor of an entire building to which these embodiments are applied. In the figure, the locations where the low floor panels 3, 3' are placed are indicated by X marks. 21 is a staircase.

〔Effect of the invention〕

The floor structure of the present invention provides a floor surface with a difference in height between the high floor panel and the low floor panel. In this case, since the raised panel is joined to the raised panel fixture provided on the upper surface of the floor beam, the raised panel can be installed without making the floor beam have a high cross-sectional shape. Therefore, the cost of floor beams is low. Since the raised floor panel fixtures only need to be provided at a portion in the longitudinal direction, the material cost is lower than when the entire floor beam is made to have a large cross-sectional shape.
