[Industrial applications]

 When assembling a long outer wall panel into a building, there is a construction mode in which a plurality of outer wall panels are previously fixed to a mounting frame to form one unit, and this unit is assembled into the building. The present invention relates to such an outer wall panel unit.

[0002]

[Prior art]

 Generally, one outer wall panel is assembled into a building, but in buildings with large wall areas such as factories and warehouses, an appropriate number of outer wall panels are preassembled as a unit and then assembled into the building in order. take. Especially for a long outer wall panel, it takes a lot of time and effort to build it, and it is easy to bend due to its own weight during building, so it is assembled in a unitized form. For example, an outer wall panel unit having a length of 4 to 5 m and a width of 7 to 8 m is formed by a group of outer wall panels having a width of 90 cm.

An example of such an outer wall panel unit is shown in FIG. There, a group of outer wall panels 30 are fixed to a rectangular unit frame 31 to form an outer wall panel unit. In the unit frame 31, the crosspieces 33 are fixed at regular intervals between the sides of the rectangular frame 32, and the brackets 34 for mounting the outer wall panel 30 are fixed to the crosspieces 33. The frame 32 and the crosspiece 33 are made of lightweight steel, and the bracket 34 is formed of an angle member, respectively, and they are integrated by welding. The outer wall panel 30 and the bracket 34 are fastened and fixed by a blind rivet 35 that is placed from the lower surface side of the bracket 34.

[Problems to be solved by the device]

 In many cases, the outer dimensions of the outer wall panel unit are so large that they are difficult to transport. Therefore, the work of assembling and welding the unit frame 31 and the work of fastening the outer wall panel 30 are performed at the construction site of the building. In such a construction mode, the outer wall panel 30 can be built quickly, but it takes a lot of time and effort to assemble the unit frame 31 on site. Furthermore, there was a problem in that it was difficult to align the panel walls in the same plane.

More specifically, when assembling the unit frame 31, a large number of welding steps are required, and it is necessary to perform rust prevention treatment with the same number of steps accompanying welding. It is also essential to fix the welding target with a clamp and remove it after welding. In each case, since long components are welded to form the unit frame 31, flexural deformation due to the weight of the components and welding distortion are likely to occur. In particular, it is difficult to flatten the panel mounting surface of the bracket 34 without variation. Therefore, with respect to the surface accuracy of the outer wall, a deviation in the thickness direction and a direction of the wall surface vary between the adjacent outer wall panels 30 or the adjacent outer wall panel units, and it is difficult to obtain sufficient construction quality for the entire outer wall. It is not impossible to correct the position of the bracket 34 after welding, but this requires a lot of manpower and time.

Therefore, an object of the present invention is to improve the structure of the unit frame, thereby reducing the number of steps required for assembling the unit frame and reducing the cost required for constructing the outer wall panel unit. Another object of the present invention is to allow the outer wall panel to be mounted flush with the unit frame, and even if the panel surface wall has a non-uniform portion, the entire outer wall can be processed again by adjusting it flush. To obtain an outer wall panel unit that can improve quality.
