Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel structure, and more particularly to a panel structure applied when a ceiling panel or a floor panel is formed in a building unit which is a constituent element of a unit construction building.

[0002]

[Background Art] In recent years, the unit construction method, which has been widely used for building buildings such as houses, uses modular building units such as living room units and roof units in which various parts constituting the building are assembled in a factory. After production, these building units are transported to the construction site, and at the construction site, these building units are combined to construct a unit building. Such a unit construction method has the advantages of simplifying the work at the construction site and shortening the construction period.

Generally, in a building unit, a ceiling frame and a floor beam are erected between upper and lower ends of pillars erected at four corners to form a box-shaped frame, and opposite long side sides thereof are formed. Beams for floors, that is, floor joists are erected between the floor joists in the longitudinal direction of the beam at a constant pitch, and after the floor material is attached to these floor joists, a predetermined finish is applied to the floor surface. It is formed.

Conventionally, when a floor joist is erected on a floor beam of a building unit, for example, when a C channel material having a U-shaped cross section is used as the floor beam, an upper portion extending from the web of the floor beam at a right angle. Of the lower flanges, the lower flange supports the lower surface of the floor joist, and the fixing members such as the joist fixing brackets provided at fixed intervals on the floor beam are provided with the end portions of the plurality of floor joists, respectively. It was fixedly installed and installed. The bracket is usually welded and attached to the floor beam. Further, the floor joist is formed to have a height dimension such that the upper surface thereof is substantially flush with the upper flange in relation to the floor surface.

[0005]

However, welding the brackets by the number of floor joists to one floor beam and fixing each floor joist to each bracket makes it difficult to fix the floor joists. Therefore, there is a drawback that the manufacturing efficiency of the building unit is reduced. Further, in order to make the upper surface of the floor joist flush with the upper flange, the sectional area of the floor joist must be increased, and there is a problem that the material is wasted.

The present invention has been made in view of the above circumstances, and when the beam for the floor or the ceiling is erected on the beam of the building unit, the amount of work required to erect the beam is reduced. It is an object of the present invention to provide a panel structure which can be manufactured and can save the material of the beam.

[0007]

SUMMARY OF THE INVENTION The present invention provides a panel structure in which a plurality of beamlets are connected between a pair of beams arranged at a predetermined interval at regular intervals in the longitudinal direction of the beams. The beam is connected to each other at a constant interval by a connecting member, and the beam is provided with a fixing member for fixing the beam every one or a plurality of beams. I am trying.

The beam is formed in a U-shaped cross section having a web and upper and lower flanges extending at right angles from both ends of the web, and the connecting member is continuous in the longitudinal direction of the beam and the lower flange of the beam is formed. It is characterized in that it is arranged above and the beam is supported on this connecting member.

[0009]

In the present invention, a plurality of beamlets installed between the beams are connected to each other by a connecting member, and in this state, the beam members are fixed to the beam by one or every other beam by the fixing member. . That is, since the beam members are connected to each other by the connecting member, it is possible to connect the beam members to the beam without fixing all the beam members to the floor beam. Therefore, the number of fixing members for fixing the beam to the beam can be small.

Further, according to the present invention, a member having a web and upper and lower flanges extending at right angles from both ends of the web is used as a material for the beam, and on the lower flange,
A connecting member that is continuous in the longitudinal direction of the beam is arranged, and the beam is supported on this connecting member. In other words, since the lower surface of the beam is not directly supported by the lower flange but is supported by the connecting member, the cross-sectional area of the beam can be reduced by the integral of the connecting member.

Embodiments of the panel structure according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a schematic perspective view of a building unit to which a panel structure according to an embodiment of the present invention is applied, FIG. 2 is an enlarged perspective view of an essential part of the building unit of FIG. 1, and FIG. Of the beam, that is, the floor plan of the building unit on which the floor joists are erected,
FIG. 4 is a cross-sectional view of a main part of a floor joist installed on the building unit.

The building unit 10 of FIG. 1 includes a column 12, a ceiling beam 14 in the long side direction, and a ceiling beam 1 in the long side direction in the short side direction.
5, a floor beam 16 in the long side direction, a floor beam 17 in the short side direction, and the like.

Two ceiling beams 14 and 15 and two floor beams 16 and 17 are bridged between the upper ends and the lower ends of the columns 12 erected at the four corners, whereby the framework of the rectangular parallelepiped building unit 10 is framed. Are formed. Here, what is used as the material of the pillar 12 is a square pipe having a rectangular cross section, and the ceiling beams 14 and 15 and the floor beams 16 and 17 are C channel materials having a U-shaped cross section.

As shown in FIG. 2, a plurality of floor joists 18 are installed between floor beams 16 in the long side direction, and floor finishing materials (not shown) are applied to the floor joists 18 to form a building unit. Ten floors are formed.

On the other hand, the floor beam 1 on which the floor joist 18 is erected.
Reference numeral 6 denotes a web 16A, and an upper flange 16B and a lower flange 1 extending from both ends of the web 16A at right angles.
6C and. A connecting member 20 is arranged above the lower flange 16C of the floor beam 16 in the longitudinal direction of the floor beam 16. The connecting member 20 is preferably a wooden square member or the like whose height dimension is approximately one half between the upper and lower flanges 16B and 16C.

The lower surface of the floor joist 18 abuts on the upper surface of the connecting member 20 and is fixed by driving a nail obliquely into the connecting member 20. That is, the plurality of floor joists 18 that are erected on the floor beam 16 are connected to each other via the connecting member 20 with a constant space. Therefore, the floor joist 18 can be shorter than the conventional floor joists directly supported on the upper side of the lower flange 16C.

A bracket 22 as a fixing member for the floor joist 18 is welded to the inside of the floor beam 16. As shown in FIG. 4, the bracket 22 is provided with a web 16
A is welded to the lower flange 16C,
The lower end 22A is notched so as not to interfere with the connecting member 20.

The brackets 22 are attached to the floor beams 16 so as to be spaced apart from the plurality of floor joists 18 laid on the floor beams 16. Therefore, as shown in FIG. 3, every other one of the floor joists 18 is fixed to the bracket 22 at the end portions 18A thereof.

Here, regarding the floor joist 18 not fixed to the bracket 22, the lower surface thereof is joined and supported on the connecting member 20 and is adjacent to the floor joist 18 via the connecting member 20.
Since all the floor joists 18 are connected to the floor joists 18 fixed to the bracket 22, it is not necessary to connect all the floor joists 18 to the floor beams 16. Therefore, it is possible to reduce the number of brackets 22 required for fixing the floor joist 18 as a whole.

The operation of the panel structure according to this embodiment constructed as described above is as follows.

First, as shown in FIG. 2, when the building unit 10 is manufactured in a factory, a plurality of brackets 22 are attached to the floor beam 16 at predetermined intervals by welding or the like. The brackets 22 are spaced apart from each other with respect to the plurality of floor joists 18 to be installed. Then, the connecting member 20 is attached to the lower flange 16C of the floor beam 16 in the longitudinal direction of the floor beam 16.

Next, the lower surfaces of both ends of the floor joist 18 are brought into contact with the upper surfaces of the connecting members 20 and sequentially joined, and the floor joists 18 installed between the floor beams 16 are connected to each other. Then, the end portion 18A of the floor joist 18 is joined to the bracket 22. Here, since the brackets 22 are attached to the floor beams 16 so that the brackets 22 are spaced apart from the floor joists 18, the floor joists 18 are attached to the floor beams 16 via the brackets 22. Will be fixed to. As a result, as shown in FIG. 3, every other floor joist 18 is fixed to the bracket 22, and the floor joist 18 is installed between the floor beams 16.

In this embodiment, the connecting member 20 is connected to the floor beam 1.
The floor joists 18 are joined to the connecting member 20 after being attached to the lower flange 16C of No. 6, but the floor joists 18 are previously connected to each other with the connecting members 20 maintaining a constant interval, In this state, every other liner joist 18
The end portion 18A of the above may be fixed to the bracket 22.

Thus, according to this embodiment, the floor joist 1
In the state in which 8 are connected to each other by the connecting member 20, every other one is fixed to the bracket 22 of the floor beam 16. Therefore, the floor joists 18 can be installed between the floor joists 16 without fixing all the floor joists 18 to the floor joists 16. Therefore, the bracket 22 attached to the floor beam 16
It is possible to reduce the number of s, and the cost is reduced accordingly. Moreover, the amount of work for welding the bracket 22 to the floor beam 16 and the amount of work for fixing the floor joist 18 to the bracket 22 are reduced.

Further, since the floor joist 18 is fixed to the inside of the floor joist 16 through the connecting member 20 supported by the lower flange 16C of the floor joist 16, the floor joist 18 has the same upper surface level as the conventional one. In this case, the cross-sectional area of the floor joist 18 can be reduced by the cross-section integration of the connecting member 20.
It is possible to save wood and the like used as the material of the. That is, conventionally, a floor joist having a height from the lower flange 16C to the upper flange 16B was used, but in the present embodiment, a floor joist having a size smaller by the height of the connecting member 20 may be used.

In this embodiment, the floor joists 18 are joined and supported on the upper surface of the connecting member 20 to connect the floor joists 18 to each other. However, the present invention is not limited to this. The method of connection, such as connecting them to each other, is not limited to this. Further, in the present embodiment, the floor girders erected on the floor girders of the building unit, that is, the floor joists are described, but the present invention is applied to the ceiling girders erected with the ceiling girders 14. It is also possible to do so.

[0028]

As described above, according to the present invention,
Since the number of fixing members to be attached to the beam to fix the beam is small, the amount of work to attach the fixing member to the beam and the amount of work to fix the beam to the fixing member are both reduced, which improves the manufacturing efficiency of the building unit. Improvement is achieved. Moreover, since the cross-sectional area of the beam can be reduced, the material of the beam can be saved.
