DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel suitable for suspending operation, a building unit including the wall panel, and a method of suspending a building unit.

[0002]

2. Description of the Related Art A building unit system, which is a system for realizing industrial production of houses, is a method of assembling a three-dimensional building unit of a predetermined size that can be transported at a factory and joining a plurality of units at a building site. Since the building unit is to be completed, it is necessary to suspend these building units during construction work.

Various schemes have been proposed for wall panels and building units that provide safe and easily suspended building units. As one of the representative examples, for example,
A building unit disclosed in JP-B-59-50835 may be mentioned. In this proposal, at the upper four corners of a building unit, a frame fitting for locking a hanging fitting between an outermost vertical frame of a wall panel constituting the building unit and a vertical frame adjacent to the vertical frame is placed. This is a building unit in which the metal fittings are supported by pins extending over both vertical frames, and are suspended using hanging metal fittings locked to the frame metal fittings.

The above-mentioned building unit will be described in detail with reference to FIGS. FIG. 7 is a vertical sectional view of the wall panel constituting the building unit as viewed from the front outside. The building unit includes a wall panel having a wall frame assembled by a vertical frame 21, an upper frame 22, and a lower frame 23, and a floor panel 10 including a joist 11 and a floor panel 12. The outermost vertical frame 21a and the vertical frame 21b adjacent to the outermost vertical frame 21a are arranged at a predetermined close interval, and a spacer 4 is inserted between them, leaving a space 3 of a predetermined height. Reference numeral 22 a denotes a bolt insertion hole formed in the upper frame 22 and communicates with the space 3.

[0005] Above the space 3, a metal-made square metal fitting 5 is disposed, and a welding nut 5 is attached to the inner surface of the top of the metal fitting 5.
1 is welded. A suspension bolt (for example, eyebolt 9) can be screwed into the welding nut 51 through the bolt insertion hole 22a.

The pin 6 penetrates the frame fitting 5 and
It is inserted through the insertion holes 7a of the vertical frames 21a and 21b of the wall panel. A suspension eyebolt 9 is attached to the welding nut 51 of the frame fitting 5.
Is screwed into the eyebolt 9 and lifted by a lifting jig (for example, a hook-shaped jig), the pin 6 is held by the vertical frames 21a and 21b, and can be lifted by the shearing force of the pin 6. ing.

[0007]

However, the conventional wall panel having a suspending structure as shown in FIG. 7 has a space between an outermost vertical frame 21a and a vertical frame 21b adjacent thereto. Since the frame fitting 5 in which the welding nut 51 is welded is housed on the inner surface of the top part, the distance (X in FIG. 7) between the outer end surface of the outermost vertical frame 21a and the inner end surface of the adjacent vertical frame 21b is Requires a certain distance. Typically, this distance (X) will be greater than the thickness of the wall panel. Although there is no problem in assembling a building unit using the wall panel having the suspending structure of the related art as an outer wall panel, when assembling a building unit using the wall panel as a partition panel in a living space, the following is required. Such a problem may occur.

Referring to FIG. 8, a problem in assembling a building unit using a conventional wall panel having a suspension structure as a partition panel will be described. FIG. 8 is a partially cutaway perspective view showing a part of a building unit assembled from wall panels having a prior art suspension structure. 10
Is a floor panel of a building unit, and a floor panel 12 is attached to an upper surface assembled in a square by joists 11. 2a is a wall panel having a conventional suspending structure. The wall panel 2b is, like the wall panel 2a, a vertical frame 2
1, 21... And an upper frame 22 and a lower frame 23. An inner wall member 24 and an outer wall member 25 are provided on both the inner and outer surfaces of the wall frame member.

The wall panel 2a is disposed along one side edge of the floor panel 10, and the wall panel 2b is disposed along a side edge adjacent to the one side edge. It is erected.

The wall panel 2a is used as a partition panel, and as shown in FIG. 8, a large opening B is formed in the wall panel 2a, and the wall panel 2a is used as a passage to a building unit connected next to the building unit or as a common living space. In this case, the end of the wall panel 2a in which the suspension structure is housed protrudes (Y in FIG. 8), thereby narrowing the passage or impeding the livability. In addition, the appearance is also impaired.

Y is the distance (X in FIG. 7) between the outer end face of the outermost vertical frame 21a containing the hanging structure of the wall panel 2a and the inner end face of the adjacent vertical frame 21b. This occurs because the thickness is larger than the thickness of the wall panel 2b that abuts on the corner at a right angle.

In the above-mentioned conventional building unit, it is necessary to screw and remove the eye bolt 9. For this reason, screwing and removing the eyebolt 9 requires man-hours on site, and the eyebolt 9 is easily lost at a construction site, resulting in frequent cost loss.

The object of the present invention has been made in view of the above-mentioned circumstances, and there is no need for an eyebolt and no cost loss of losing the eyebolt. Part, a passage is secured, a wall structure provided with a suspension structure that does not impair habitability and does not impair the appearance, a building unit comprising the wall panel, and a suspension of the building unit It is to provide a method.

An elongated hole for inserting a pin laid on each of the vertical frames is formed in the center of the flat plate portion, and a hole for locking the convex portion of the hanging bracket is provided in the upper frame of the wall panel. Since it is perforated, it is possible to make the space between the vertical frames narrower than when using the frame fitting of the prior art, and even when used as a partition panel, a sufficient opening is secured in the partition part It is possible to secure a passageway, not hinder the livability, and does not impair the appearance.

In the building unit according to the second aspect of the present invention, the wall panel according to the first aspect of the present invention is erected along at least one side edge of the rectangular floor panel, and a ceiling panel is mounted on the upper part of the wall panel. Since the building unit using the wall panel as the partition panel can secure a sufficient opening in the partition part, the passage is secured, the livability is not impaired, and the appearance is impaired. Absent.
In addition, eyebolts are not required for suspending the building unit according to the second aspect of the present invention, and there is no cost loss due to loss of eyebolts.

The method for suspending a building unit according to the third aspect of the present invention relates to the above-described method for suspending a hanging bracket provided on the wall panel of the first aspect constituting the building unit at at least one of four corners of the building unit of the second aspect. Since the suspension jig is engaged through the mounting holes and the building unit is suspended using the suspension jig, the building unit can be suspended safely and easily. In addition, the method of the third aspect of the present invention does not require an eyebolt, so that there is no cost loss of losing the eyebolt.
