Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for assembling box-shaped structures such as housing units, freight shipping containers, etc.

When assembling a box-shaped structure, the top member, bottom member, and side member are each prepared in advance, and the lower edges of the side members are joined to both side edges of the bottom member, respectively, and erected. If a method is adopted in which both side edges of the top member are joined to the upper edges of both side members, the joining work will be performed on both sides of the bottom member, that is, at three locations.

The larger the box-shaped structure is, the more it is industrially mass-produced, the more the production relies on mechanical power, and the more equipment is lost, but as mentioned above, the joining work is done in three places. If this is done separately, equipment and personnel will be required for supplying and joining the side members for each.

Also, if you attempt to assemble a box-shaped structure of a different size following the previously assembled box-shaped structure, the location of the joining work will shift to match the size of the bottom member, and as a result, the side member It is necessary to change the supply route and move the bonding equipment.

Furthermore, when joining, it is desirable to install a jig to accurately align the angles and positions of the parts, but if the work place for joining moves, the location of this jig must be adjusted each time. It may also be necessary to reinstall it.

The present invention has been made in an attempt to solve these difficulties and streamline the industrial production of box-shaped structures. When assembling a box-shaped structure by joining the front side member and the rear side member to each other, the front side member is held in an upright state, and the top side member and the bottom side member are drawn out toward the front side member. , one edge of the top surface member and the bottom surface member are joined to the upper and lower edges of the front surface member, respectively, and then, each of the joined surface members is joined, and the joined front surface member becomes the transport front surface. direction and until it passes the place where the front side member is joined, and at a place where the front side member is joined or adjacent thereto, the rear side member is held in an upright state, and the back side member is The joined surface members are fed out in a direction opposite to the transfer direction, and the other edges of the top surface member and the bottom surface member are joined to the upper and lower edges of the rear surface member, respectively. The invention consists in a method of assembling a box-shaped structure.

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

FIG. 1 shows an example of each side member assembled into a box-shaped structure.

In the figure, reference numeral 1 denotes a top member, in which a small beam 12.
12... The frame consists of a frame that has been assembled by being passed and joined.

The frame consists of a frame in which small beams 22, 22, etc. are passed and joined between 1 and assembled.

Reference numerals 3 and 3 denote a front side member and a rear side member, in which beam members 32 and 32 made of lightweight C-shaped steel are placed between the upper and lower ends of column members 31 and 31 made of rectangular steel pipes arranged in parallel and facing each other, respectively. It consists of a frame-shaped frame that is assembled by welding.

Reference numerals 33, 33, . . . denote joint portions, which are made of short groove-shaped members, and are welded and protruded from the four corners of the back surface of the side member 3°3, respectively.

The top member 1 and the bottom member 2 are vertically opposed to each other,
At these side edges, each side member 3゜3 connects its joint portion 33, 33... to each beam member 11゜11.21, respectively.
The ends of 21 are inserted into the grooves of the lightweight C-shaped steel and abutted, and are welded together to form a box-shaped structure.

In addition, each beam material 11, 11, 2 is attached to the joint parts 33, 33...
The end portion of 1.21 may be brought into contact with the inserted state, or the connection may be made by bolts or nuts.

In this example, the top member 1, the bottom member 2, the side members 31 and 3
Each member is made as a frame, and the box-shaped structure assembled from these is a three-dimensional structure in which the beams and columns of each member are arranged along the ridges of a rectangular parallelepiped and connected to each other. It has a frame-like structure.

Note that the provision of the joint parts 33, 33... ensures accurate alignment of the joints of each surface member, and also allows the beam members 11, 11
゜21.21... If there is a variation in length, the variation can be eliminated by adjusting the overlapping length with the joint 33, and furthermore, it is possible to make a connection that does not force mechanical transmission. Good results can be obtained.

In this box-shaped structure, a face member is further attached between the beam material and the column material of each member depending on the purpose.

For example, if this box-shaped structure is made into a housing unit,
In other words, a box-shaped structure in which a house is constructed by connecting a plurality of box-shaped structures front to back, left to right, or top to bottom,
In this case, depending on which part of the house it consists of,
A ceiling material and a roof material are attached to the top member 1, a floor material is attached to the bottom member 2, and side members 3, 3, beam members 11, 21, .
An outer wall material may be attached to the surface portion surrounded by the pillar material 31 as required, or may be left open without being attached.

The top member 1, the bottom member 2, and the side member 3 are not limited to being in the framework as described above, but may be made in advance as panels.

This panel may be one in which a panel is attached to the above-mentioned frame or concrete is poured into it, and although there is no special frame to form the three-dimensional frame-like frame, each panel has its own capacity. It may also be a panel that forms a wall structure.

FIGS. 2 and 3 show an example of a method for assembling the box-shaped structure of the present invention.

In the figure, 4 and 5 are concrete, respectively, and the top member 1
and the bottom member 2 are placed thereon and transferred along the transfer path from left to right in the figure.

Note that the vertical spacing between the conveyors 4 and 5 is set to match the height of the side member 3, so that the top member 1 and the bottom member 2 are spaced vertically to match the height of the side member 3. They will be transported simultaneously or one after the other while being supported by the robot.

Reference numeral 6 denotes a movable frame, which holds the front side member 3a and the rear side member 3b back to back and sends them from the standby place A to the joining operation place B in the transfer path I of the top member 1 and the bottom member 2.

At the joining operation location B, the front side member 3a and the rear side member 3
b is held on the movable frame 6 in an upright state with its surface perpendicular to the direction of transfer of the top member 1 and the bottom member 2.

Thus, the top member 1 and the bottom member 2 are either temporarily stopped just before the welding operation lifting station B, or are the front side members held as they are at the welding operation place B as described above without stopping. 3a, front side member 3
The front edge 13 of the top member 1 and the front edge 23 of the bottom member are joined to the upper and lower edges of a, respectively.

After performing this joining, the front side member 3 on the movable frame 6 is
a is released, the movable frame 6 is moved back to the standby place A, and the top member 1 and bottom member 2 of the front side member 3a are moved in the direction where the front side member 3a is the front side of the transfer (right side in the figure). direction).

At the front in the transfer direction, a comparator is placed across the welding operation location B.
-7 is provided, and each of the joined surface members is transferred to this conveyor 7 and stopped.

Next, the movable frame 6 is returned to the welding operation location B, and in this movable frame 6, the movable frame 6 is moved toward the rear side member 3b, which is held in an upright state and perpendicular to the transfer direction of the top and bottom members 2. , the top member 1 and the bottom member 2 are fed out, and the rear edge 1 of the top member 1 is placed on the upper and lower edges of the rear side member 3b.
4. Join the rear edges 24 of the bottom members, thus forming a box-shaped structure.

When assembling a plurality of box-shaped structures one after another, the front side members 3b, which are also held on the movable frame 6, are joined simultaneously or in parallel with the work of joining the rear side members 3b held on the movable frame 6. The member 3a may be joined to the succeeding top member 1 and bottom member 2 in Compete I7-4 and 5 soil.

In this way, the movable frame 6 holds the front side member 3a and the rear side member 3b at the same time, and one is used as the top member 1 and the bottom member 2 of the conveyors 4 and 5, and the other is used as the conveyor 1--7.
When joining the top surface member 1 and the bottom surface member 2, respectively, the rear surface member 3b is joined at a location close to the location where the front surface member 3a is joined.

In the above-mentioned example, the front side member 3a and the rear side member 3b are joined while being held by the movable frame 6, but in the present invention, the front side member 3a and the rear side member 3b are
After being delivered to the welding operation site (transfer path for the top member 1 and bottom member 2) by the movable pedestal 6, it may be taken down from the movable pedestal 6 and held in an upright position for welding.

For holding, a holding jig that can be retracted from the transfer path by reciprocating or rotating up and down or back and forth is arranged around the side member at the joining operation location B. You can decide to set it up.

The former method, in which the parts are joined while being held on the movable pedestal 6, simplifies the device and operation, while the latter method, in which the parts are joined once from the movable pedestal 6, requires the movable pedestal 6 to be returned to the standby location A. By holding and waiting the next front side member and rear side member, time can be saved, and the movable frame 6
By lowering and holding the side members, it is possible to more reliably hold each side member and accurately position it.

As described above, in the present invention, when assembling a box-shaped structure by joining the top member, the bottom member, the front side member, and the rear side member to each other, one edge of the top member and the bottom member The front side members are first joined, and then the rear side members are joined at the location where the front side members were joined, or at a location close to it, so the joining work is concentrated in one place. Therefore, it is possible to avoid dispersion and movement of the joining device, side member supply device, workers, etc.

Also, since the joining work location is always fixed at a fixed position regardless of the length of the top or bottom members, even if the lengths of the top and bottom members change, the positioning can be adjusted accordingly. It is not necessary to move the equipment from one to another.

Therefore, in a continuous assembly process using an assembly line system, it is possible to assemble box-shaped structures of different sizes following the preceding one without interrupting the assembly work.

As described above, the assembly method of the present invention is extremely suitable for mass production of a wide variety of box-shaped structures.
