Description

TECHNICAL FIELD The present invention relates to an assembly device for a building unit.

[Prior Art] One method of increasing the industrial production rate of buildings is a unit building method. In this unit building system, a single building is divided into a plurality of building units in which wall panels are fixed to side edges of floor panels, and each unit is, for example, disclosed in JP-A-51
After producing in a factory as shown in the -113265 publication, those units will be transported to a construction site and installed on the foundation prepared beforehand.

Here, a conventional building unit assembling apparatus is disclosed in Japanese Patent Laid-Open No.
As shown in Japanese Patent No. 13265, a movable pedestal capable of holding a panel can be moved from a loading position of the panel to a joining position with another panel along the left and right guide rails.

[Problems to be Solved by the Invention] However, in the above-mentioned conventional apparatus for assembling a building unit, the wheels of the movable base are simply mounted so as to be able to travel on the guide rails. Therefore, when a relatively large external force for joining acts on the panel held by the moving base and another panel, the moving base is displaced with respect to the guide rail, and both panels are moved. There is a risk that the two panels will be fixed in a state where there is a positional deviation between them. Further, in the above-mentioned conventional building unit assembling apparatus, since the guide rails are provided on the basic frame, it is very dangerous for the operator to have many accidents such as being caught in his / her feet.

It is an object of the present invention to enable a panel to be held on a movable gantry and to fix the panel and other panels in a state where the panel and other panels are maintained in an appropriate fixed positional relationship, and at the same time, to improve the safety of work by an operator. To do.

[Means for Solving Problems] According to the present invention, it is possible to move a movable pedestal capable of holding a panel from a carry-in position of the panel to a joining position with another panel along the left and right guide rails. In the assembly unit for building units, each guide rail is provided inside the foundation frame, each guide rail is provided with a restraining rail surface, and restraining wheels are provided on the moving base to move in the direction crossing the rail longitudinal direction. The restraint wheel is brought into rolling contact with the restraint rail surface so as to prevent displacement of the carriage.

[Operation] According to the present invention, the movable mount can prevent displacement in a direction intersecting the rail longitudinal direction at any position on the guide rail. Therefore, even if a relatively large external force for joining is applied during joining work between the panel held by the movable base and another panel, the two panels are not displaced, and both panels are not displaced. Can be fixed while maintaining an appropriate fixed positional relationship. At the same time, the worker does not get caught in the legs of the guide rails or kicks, which increases work safety.

Supported by 1. The first drive cylinder device 39 allows the clamp arm 38 to swing as described above. The clamp hand 40 is provided on the clamp arm 38 and can contact the girder wall panel 13. The second drive cylinder device 41 enables the clamp hand 40 to be pressed against the girder wall panel 13.

Next, the crane wall panel 12 is assembled with the crane 20 by the crane 20.
Carry it inside. As shown in FIG. 6 (B), the lower end portion of the end panel 12 is placed on the end portion of the floor panel 11 on the end side, and the lower end extension 12B of the drawing material 12A is attached to the end portion of the floor panel 11. It will be arranged outside of the side surface on the side. In addition, the lower end extension portion 12B of the face material 12A is the floor panel 1
1 will constitute the face material of the above-mentioned side surface.

Next, similarly to the temporary holding work of the girder wall panel 13 shown in FIG. 5, the gable wall panel 12 is fixed to the pedestal 23 by the wall clamp devices 27 provided in the movable pedestal 23 and the fixed pedestal 24, respectively. It is temporarily held in each of 24.

Next, as shown in FIG. 5 and FIG.
3. The setting device in the girder direction of each panel 11, 12, 13 is adjusted by the pressing device 42 provided on the fixed frame 24 and the side roller 43 provided on the base frame 21. The side roller 43 is set on the same level surface as the reference surface 37 of the wall clamp device 27. The side roller 43 functions as a reference receiving portion of the floor panel 11 and the girder wall panel 13 in the girder direction, and simultaneously abuts on each side surface of the floor panel 11 and the girder wall panel 13 on the cut surface side so that both side surfaces are flush with each other. Can be set to. At this time, it is assumed that the lower end extension portion 13B in the image 13A of the girder wall panel 13 constitutes the side surface of the floor panel 11.

The pressing roller 45 of the pressing device 42 also functions as a reference receiving portion for the floor panel 11 and the gable wall panel 12 in the girder direction.
As shown in the figure (B), floor panel 11 and gable wall panel 12
Both side surfaces can be set on the same surface by simultaneously contacting the respective side surfaces on the front surface side. As a result, each panel 11, 12, 13
Means that the set position is adjusted to the proper position from the state shown by the two-dot chain line in FIG. 6 (C) to the state shown by the solid line.

Next, the movable mount 23 is moved from the panel loading position to the panel joining position, and the setting positions of the panels 11, 12 and 13 in the end direction are adjusted. That is, the respective panels 11, 12, 13 whose setting positions in the girder direction have been adjusted as described above.
Is narrowed between the reference receiving portion 46 of the movable base 23, the reference receiving portion 47 of the fixed base 24, and the reference receiving portion 36, and the setting position in the end direction thereof is adjusted to an appropriate position. Becomes

Next, as described above, the clamp hand 40 of the wall clamp device 27 is operated under the condition that the respective panels 11, 12, 13 are set to their proper holding positions, and the respective wall panels 12, 13 are removed. It presses against each reference surface of each pedestal 23, 24, 31 and securely holds each wall panel 12, 13 in their proper holding position.

Next, the panels 11, 12, and 13 securely held in the proper holding positions as described above are nailed to each other to obtain the building unit 10. Then, each device of the assembling device 20 is returned to the original position, and the building unit 10 is carried out by the crane.

Therefore, according to the above-described embodiment, the movable pedestal 23 can be prevented from being displaced at a position on the guide rail 22 in a direction intersecting the rail longitudinal direction. Therefore, even when a relatively large external force for joining is applied during joining work between the panel held by the movable mount 23 and another panel, the positions of both panels are not displaced. Can be fixed while maintaining an appropriate fixed positional relationship.

[Advantages of the Invention] As described above, according to the present invention, it is possible to move a movable base capable of holding a panel from a carry-in position of the panel to a joining position with another panel along the left and right guide rails. In the assembly unit for building units, each guide rail is provided inside the foundation frame, each guide rail is provided with a restraining rail surface, and restraining wheels are provided on the moving base to move in the direction crossing the rail longitudinal direction. The restraint wheel is brought into rolling contact with the restraint rail surface so as to prevent displacement of the carriage. Therefore, it is possible to hold the panel on the movable base and fix the panel and the other panel in a state where the panel is maintained in an appropriate fixed positional relationship. At the same time, the worker's foot is not caught in the guide rail or kicked, which increases work safety.
