Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a panel-assembled building unit that is a load-bearing wall suitable for lifting operations.

The building unit method, which is known as a method for industrializing housing, assembles building units in a factory as three-dimensional structures of a predetermined size that can be transported, and then connects multiple units at the construction site to construct a building. Since these building units are completed, it is necessary to lift these building units during construction work.

When a building unit has a steel frame with pillars and beams at the four corners connected to a rigid frame structure, it is generally done to attach a hanging bracket to the frame and lock a lifting jig thereto to lift it. ing.

However, if the building unit is assembled from panels that serve as load-bearing walls and does not have a particularly strong frame as described above, the above-mentioned lifting method cannot be adopted.

The present invention has been made in view of the above-mentioned points, and includes a frame metal fitting for locking a hanging metal fitting, which is housed in the upper part between a pair of adjacent vertical frames at the four corners of a building unit, and this frame metal fitting is inserted between both vertical bars. To provide a building unit that can be easily and safely lifted up without being damaged by supporting it with pins.

Next, the present invention will be explained with reference to the drawings.

FIG. 1 shows an example of a building unit according to the present invention.

In the figure, 1 is a floor panel of a building unit, and joists 11. '11. A facing material 12 such as structural plywood or particle board is attached to the upper surface of a floor frame assembled into a rectangular shape.

2a, 2a and 2b are wall panels, all of which are
Vertical frame 21, 21. It has a wall framework assembled by an upper frame 22 and a lower frame 23.

In the wall framework of the wall panels 2a and 2a, the vertical frame 21 on the furthest side
a, 21a and the vertical frames 21b, 21 adjacent to both of them, respectively.
b are arranged close to each other.

However, one of the wall panels 2a, 2.a has an opening A.

The wall panels 2a, 2a are arranged along a pair of opposite edges of the floor panel 1, and the wall panel 2b is arranged along the other side edge, and a lower frame 23 is nailed to the floor panel 1, respectively. Due to this, it is erected.

The wall panels other than the wall panel 2a having the opening A are made into load-bearing walls by having facing materials 24 such as gypsum board or wood cement board attached to both the inside and outside of the wall framework, and the outside facing material 24 is a floor panel. It has grown to 1.

In addition, interior and exterior finishing is also applied to the outside of these panel members 24, and a heat insulating material and the like are also loaded inside each wall panel.

Note that although a facing material 24 is also attached to the wall frame of the wall panel 2a having the opening A, the facing material extending over at least the outermost part and the floor panel 1 is not attached.

The adjacent wall panels 2a and 2b are tightly connected by nailing the outermost vertical frames 21 of the wall frameworks against each other.

The illustrated building unit is an example in which wall panels are erected on three side edges of a floor panel 1, and one of the opposing wall panels 2a, 2a has an opening A. Wall panels are erected depending on whether the floor panel 1 is to be constructed or not, and are erected on at least one pair of opposing side edges of the floor panel 1.

Also, no ceiling panels are specifically attached to the illustrated building unit.

A separately prepared roof is installed on top of the wall panel, or the floor panel of the building unit on the upper floor installed on top of this is used as the ceiling of the building unit on the lower floor. However, the building unit in the present invention may be one to which a ceiling panel is attached.

2 and 3 are vertical cross-sectional views of the outer portion 1 of the wall panel 2a as viewed from the X-X arrow direction and the Y-Y arrow direction in FIG. 1, respectively.

As shown in the figure, the outermost vertical frame 21a and the adjacent vertical frame 21b are arranged at a predetermined close interval, and a space 3 of a predetermined height is provided above between them. All that remains is a spacer 4 inserted.

22a is a bolt insertion hole bored in the upper frame 22 and communicates with the space 3.

Reference numeral 5 denotes a frame metal fitting for a bolt receiver having an opening shape, and a female threaded portion 51 is provided at the upper part, and this female threaded portion 51 is held in the space 3 by a screw 6 so as to face the bolt insertion hole 22a. has been done.

The frame metal fitting 5 is sized so that no large play occurs between it and the vertical frames 21a and 21b.

The pins 6 are inserted into pin holes 7a, 7a formed oppositely in the vertical frames 21a, 21b, respectively.

Similarly, between the vertical frames 21a and 21b on the other outermost side of the wall panel 2a, a frame metal fitting for a bolt receiver is held with a pin, and a bolt insertion hole opposite the female threaded part is bored in the upper part. ing.

Among the wall panels 2a, 2a, the wall panel 2a which has the opening A and to which the facing material 24 is not attached over at least the outermost part of the wall framework and the floor panel 1 has a structure as shown in FIG. An L-shaped reinforcing member 8 is attached from the outer surface of the vertical member 21 to the bottom surface of the floor panel 1.

However, in order to lift a building unit using a lever, a hanging fitting 9 is screwed into the frame fitting 5 for the bolt receiver through the bolt insertion holes 22a at the four corners, and a lifting jig 10 is attached via the hanging fitting 9 as shown in FIG. This is done by concatenating to

In this lifting method, when lifting, the emphasis is on the upper parts of the four corners of the building unit, that is, the engagement parts with the pins 6 of the vertical frames 21a and 21b, but the emphasis is on the upper parts of the four corners of the building unit, that is, the engagement parts with the pins 6 of the vertical frames 21a and 21b. On the side, the load of the floor panel 1 is applied via the panel 24 to the vertical frames 21a, 21b whose upper part is the focus, and the wall panel is also On the side without the floor panel, the load of the floor panel 1 is applied to the vertical frame 21a via the reinforcing member 8, so there is no need to hang multiple ropes from the bottom of the building unit to prevent separation of the floor panels. It can be lifted without straining.

As described above, according to the present invention, the space between the adjacent vertical frames at the four corners of the building unit is utilized, and the upper part of this space is
Since the frame metal fittings that lock the hanging metal fittings are inserted and held by the above-mentioned vertical frames via pins, when lifting,
Just like when you have a steel frame joined to a rigid frame structure, you just need to insert and lock the hanging fittings into the four corners above and release the locks when the lifting is finished. To easily and safely lift a building unit that does not have a frame of a rigid frame structure without fear of deformation or damage.
