Abstract

PURPOSE:To aim at the highly accurate and highly efficient fabrication of an outer wall material, by setting plural wall panels against a tilting workbench upon mounting them on a lot of rollers after placing plural studs against the workbench, while making each stud hole accord with each panel hole, and connecting them with a connecting device without play. CONSTITUTION:Plural studs 70 are tilted at the same angle as that of a workbench 13 and set up at the specified position, while a lower end part of a wall panel 60 is mounted on a roller 42, putting vertical frame 63 on a roller 44 or 46, and the wall panel 60 is supported as tilted to the same angle as that of the workbench and supported free of horizontal movement by the roller. Next, the wall panel 60 is horizontally moved to these studs 70, while insertion holes 64 of these vertical frames 62 is made to accord with insertion holes 75 of these studs 70, inserting a rivet 90 into them, and crosspieces 62 of the adjacent wall panel 60 are connected to the common stud 70 whereby wall panels themselves are connected together and thus an outer wall material is fabricated. When the rivet 90 is inserted into each of insertion holes 64 and 75, there is almost no play so that the outer wall material is efficiently constructible in a highly accurate manner.

Description

[Detailed description of the invention] (Technical field of invention) The present invention relates to a method for assembling exterior wall materials.

(Prior Art) A method of building a house by manufacturing box-shaped house units in advance in a factory and assembling a plurality of house units at a construction site has become popular. The house unit first assembles a box-shaped frame structure, transports this frame structure along a conveyance line,
It is obtained by assembling various constituent materials to the frame structure during this transportation process.

Conventionally, all the work of forming the outer wall material on the frame structure was performed on the above-mentioned conveyance line. Specifically, multiple studs are attached to the frame structure on the conveyance line, and then small-area wall panels are connected one by one to the studs to form a large-area exterior wall material. Was.

The above connection is performed using a connecting tool such as a bolt. Specifically, an insertion hole is formed in the stud, and an insertion hole is also formed in the side edge of the wall panel, and after aligning the two insertion holes, a bolt is inserted into the insertion hole to connect them. By the way, since the wall panel is held by a chuck device or the like, it is difficult to accurately adjust the position, and therefore it is difficult to completely align the studs and the insertion holes formed in the wall panel. Therefore, the insertion hole is formed to be larger than the outside diameter of the bolt, and the bolt is tightened after being aligned to the extent that the bolt can be inserted. However, in this case, the dimensional accuracy of the assembled external wall material is reduced. Therefore, in reality, the bolts mentioned above are loosened and left in a temporary state, and in this state, the wall panel is adjusted to the correct position relative to the studs, and then the port T is tightened tightly to perform the connection. Ta. As described above, the task of assembling exterior wall materials with high precision is extremely complicated.

be inserted.

In this way, the plurality of studs 70 are tilted at the same angle as the workbench 13 and are accurately installed at predetermined positions.

Next, a plurality of wall panels 60 are placed against the workbench 13.

Specifically, as shown by the imaginary lines in FIGS. 1 and 2, the lower end of the wall panel 60 is placed on the roller 42, and the horizontal beam 63 is brought into contact with the roller 44 or the roller 46. In this way,
The wall panel 60 is supported tilted at the same angle as the workbench 13, and supported so as to be horizontally movable by the rollers 42, 44, 46. After this, one of the studs installed in a predetermined position as shown in FIG. The wall panel 60 is moved horizontally with respect to the stud 70 (as indicated by the arrow FF' in FIG. 11), so that the insertion hole 64 of the vertical beam 62 is aligned with the insertion hole 75 of the stud 70. Note that the lower end of the stud 70 is supported by the receiving plate 53a,
Since the lower end of the wall panel 60 is supported by the roller 42, the heights of the insertion holes 64 and 75 are accurately positioned and no adjustment is necessary.

Next, rivets 90 (connectors) are inserted into the matching insertion holes 64 and 75. The rivet 90 includes a cylindrical portion 91 and an annular end plate portion 92 formed at one end of the cylindrical portion 91.
It has A crushing jig 93 is inserted into the rivet 90 in advance. The crushing jig 93 includes a rod-shaped portion 94 having a groove or a thread on the outer periphery, a large-diameter head 95 formed at one end of the rod-shaped portion 94 and having a red hexagonal cross section, and the rod-shaped portion 94 and the head 95. A small diameter neck 96 formed at the border between
- has. Then, by pressing the end plate part 92 of the rivet 90 using a special jig and pulling the rod-shaped part 94 of the crushing jig 93, as shown in FIG. The cylindrical portion 91 of the rivet 90 is torn apart and pushed apart. Note that when the rod-shaped portion 94 is further pulled after this, the neck portion 96 of the crushing jig 93
is destroyed.

” 2, the vertical bars 62 of the adjacent wall panels 60
By connecting the wall panels 60 to a common stud 70, the wall panels 60 are connected to each other to assemble the exterior wall material 80.

The insertion holes G4. IS
When inserting the rivet 90, there is almost no play. That is, there is almost no gap between the insertion hole 64, 65 and the rivet 90.

Therefore, the outer wall material 80 assembled by the riveting described above has high dimensional accuracy.

Next, as shown in Fig. 13, a waterproof gasket) 98
is inserted between the connected wall panels 60.

After assembling the exterior wall material 80 as described above, the exterior wall material 80 is gripped by a chuck table (not shown) and transported to a box-shaped frame structure (not shown) placed on a transport line. Attach to the side of the frame structure. That is, the outer wall material 80 is attached by connecting the end plate portion 73 of the stud 70 to the beam of the frame structure.

The present invention is not limited to the above embodiments, and various embodiments are possible. For example, bolts or self-tapping screws may be used as connectors to connect studs and wall panels. When using a tapping screw, one of the insertion holes becomes a tapped hole. Furthermore, the exterior wall material of the present invention may be attached to general buildings other than House Uni-F.

(Effects of the Invention) As explained above, according to the method of the present invention, studs and wall panels are placed against an inclined workbench, and the wall panel placed on rollers is horizontally adjusted relative to the stand positioned by the support mechanism. By doing this, it is possible to easily match the insertion holes of the wall panel with the insertion holes of the studs, and by inserting the connector into the matched insertion holes with almost no play and connecting the two, the exterior wall material can be assembled with high precision. Can be assembled.
