Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure between floors in a building allowing easy heat insulation between the floors and supporting a floor panel of an upper floor advantageously in terms of costs. <P>SOLUTION: Panel frames 3c and 4c for outside wall panels 3 and 4 in the upper and lower floors are positioned on the exterior side beyond a beam 2 between the floors and arranged to be held in a mutual proximity or contact condition without putting the beam 2 between the floors between them. In this ways, the upper and lower floors are thermally insulated from each other by means of a heat insulation material 3d on the upper floor and a heat insulation material 4d on the lower floor. A floor panel 5 of the upper floor is supported by the beam 2 between the floors. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a structure of a building floor space.

[0002]

2. Description of the Related Art In a building such as a detached house with a steel frame, for example, as shown in FIG. 3, the inter-floor section is conventionally composed of panel frames 51a, 5 of outer wall panels 51, 52 on the upper and lower floors.
2a is installed so as to sandwich the body difference 53 from the upper and lower sides, and is connected to the body difference 53, and the floor panel 54 extends a beam 55 from the body difference 53 in the indoor direction.
The structure is supported by. Reference numeral 56 is a ceiling panel.

[0003]

However, as described above, in the structure in which the panel frames 51a and 52a sandwich the body difference 53 from both upper and lower sides, the body difference 53 between the upper floor heat insulating material 51b and the lower floor heat insulating material 52b. The upper and lower parts are separated from each other by the height dimension of the
There is a problem that the heat treatment such as providing the heat insulating material 58 between the No. 3 and the makeup barrel difference 57 needs to be performed separately, which makes the construction difficult.

Further, as described above, since the panel frames 51a and 52a of the outer wall panels 51 and 52 of the upper and lower floors are present on the top surface and the lower surface of the body difference 53, the floor in the body difference area is large. Since the body difference 53 cannot be used to support the panel 54, it is necessary to attach a beam 55 to the body difference 53 and to support the floor panel 54 on the beam 55. There was also a problem that the amount used was large and the cost was high.

In view of the above-mentioned conventional problems, the present invention makes it possible to easily perform heat insulation treatment between floors and also to support floor panels on the floors at a cost advantage. It is an object to provide a structure of a part.

[0006]

[Means for Solving the Problems] The above problem is that the panel frames of the outer wall panels above and below the floor are located on the outdoor side of the inter-story beam, and are in close proximity or contact with each other without interposing the inter-story beam. It is arranged so that it is held by beams between the floors, and the floors are insulated by the heat insulating material on the upper floors and the heat insulating material on the lower floors. It

In this structure, the panel frames on the upper and lower floors are located on the outdoor side of the beams on the floors and are arranged so as to be in close proximity or contact with each other without interposing the beams on the floors. Is insulated by the insulation material on the upper floors and the insulation material on the lower floors, so the floor space can be heat-insulated easily compared to the case where heat insulation is performed separately from the insulation material on the upper and lower floors. You can

In the above structure, when the floor panel above the floor is supported by the beam between the floors, the small beam for supporting the floor panel above the floor can be eliminated or reduced,
The floor panel on the upper floor can be supported cost effectively. That is, the panel frame of the outer wall panel on the upper and lower floors is located on the outdoor side of the inter-story beam so that the panel frames are arranged close to or in contact with each other without interposing the inter-story beam. It effectively utilizes the top surface of the beam between the floors, which is effectively used to support the upper floor panel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described with reference to the drawings.

In the inter-building floor portion of the embodiment shown in FIGS. 1 and 2, 1 is a pillar, 2 is a floor beam, 3 is an outer wall panel above the floor, 4 is an outer wall panel below the floor, and 5 is above the floor. It is a floor panel.

The pillar 1 is a through pillar made of a square steel tube pillar, and the beam 2 between floors is made of grooved steel and the like, and the opening side of the groove is directed toward the indoor side, and the pillar 1 is provided on the side surface on the indoor side of the pillar 1. It is attached so as to project to the indoor side.

Further, the outer wall panels 3 and 4 on the upper and lower floors are respectively attached with L-shaped panel frames 3c and 4c on the back side of the face materials 3a and 4a via base materials 3b and 4b, respectively.
Inside the panel frames 3c and 4c, heat insulating materials 3d and 4d made of foamed resin such as foamed polystyrene, which constitute the heat insulating material on the upper and lower floors, are placed. In each of the outer wall panels 3 and 4, ventilation layers 3e and 4e are provided between the heat insulating materials 3d and 4d and the face materials 3a and 4a.

A holding plate 6 projecting to the outdoor side is attached to the beam 2 between the floors, and the outer frame panels 3 and 4 have their panel frames 3c and 4c arranged to move the holding plate 6 up and down. The panel frames 3c and 4c are arranged so as to be in close proximity to each other by sandwiching them from both sides.
The three members, the holding plate 6 and the holding plate 6, are connected and held to the inter-story beam 2 by being joined with bolts 7. At the same time, the three-sided connection allows the inter-story beam 2 to be insulated from the upper and lower floors on the outdoor side. It is insulated by the materials 3d and 4d. In addition, 8 is a drainer, and a conventional makeup barrel difference is omitted.

The floor panel 5 on the upper floor is supported by the ceiling surface of the beam 2 between the floors.

In the above structure, the panel frames 3c, 4c of the outer wall panels 3, 4 on the upper and lower floors are located on the outdoor side of the inter-floor beam 2 and do not sandwich the inter-floor beam 2, It is arranged so as to be in a close state with a holding plate 6 protruding from the inter-floor beam 2 to the outdoor side, and the outdoor side of the inter-floor beam 2 is provided on the outer wall panels 3 and 4 above and below the floor, respectively. Since it is insulated by the upper-layer heat insulating material 3d and the lower-layer heat insulating material 4d, as compared with the conventional case in which the inter-floor portion is heat-insulated separately from the upper and lower floor insulating materials, Can be heat-insulated easily.

In addition, since the top surface space of the beam 2 between the floors is used to support the floor panel 5 above the floor on the top surface of the beam 2 between the floors, as in the conventional case. It is possible to eliminate or reduce the number of special beams, and it is possible to cost-effectively support the floor panel above the floor.

Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention. For example, in the above-mentioned embodiment, the case where the upper and lower floor panel frames 3c and 4c are arranged in close proximity via the holding plate 6 is shown, but the panel frames 3c and 4c are arranged in contact with each other and the floor space is increased. The beam 2 may be held. Also,
In the above embodiment, the case where the heat insulating materials 3d and 4d are made of foamed resin is shown, but a fiber type heat insulating material such as glass wool may be used. Further, in the above-described embodiment, the case where the invention is applied to a steel frame building is shown, but the invention can also be applied to a building such as a wooden structure.
