Description

  The present invention relates to a wall panel method for building a wall structure of a wooden house in a factory in advance and then building the wall panel on site.

  Conventionally, in the construction field of wooden houses, the conventional frame construction method and the two-by-four method have been the mainstream. A construction method in which the structure constituting the “surface” is made into a panel in a factory in advance and the panel is assembled on site is becoming mainstream. For example, Patent Document 1 standardizes a panel body constituting a wall, floor, and roof of a house for each predetermined number of groups, and also normalizes the shape and size of the space constituting the house into a predetermined number of space units, A construction method is described in which a plurality of combination patterns of each panel body and space unit are set in advance, and a house is formed by combining a plurality of space units composed of combinations of panel bodies.

In the above-mentioned document, the structural material or shaft member of the outer wall part and the outer wall material and the opening are integrally attached, and a large-sized member is provided on the end surface of the beam member to engage with a coupling fitting provided on a column that is a shaft member. A construction method has been proposed in which a wall panel is constructed, and the wall panel is assembled in advance in a factory and then connected to each other at a construction site to form an outer wall portion.

  A large-sized wall panel used in the above-described construction method has a high rigidity by pre-assembling the pillars and beams together and further attaching a structural plywood on one or both sides. Furthermore, since they are processed at the factory, the dimensional accuracy of each part is also high, and the consistency of the connection part of panels is also good.

  However, on the other hand, for example, if a small dimensional error occurs in the foundation at the construction site, the height of the rigidity of the wall panel itself will come to the back, and after the wall panels are connected, the building and street are finely adjusted. It may be difficult.

  Then, this invention makes it a solution subject to provide the wall panel construction method in which the fine adjustment on the field is also possible, without impairing the advantage of the construction method by a large sized integrated panel.

In order to achieve the above-described object, the wall panel construction method for a wooden house according to the present invention is a method of polymerizing a structural face material on one or both sides of a frame composed of a beam, a lower frame material, a column, a stud, and other appropriate shaft members. In a wall panel construction method of a wooden house in which a wall panel is constructed by nailing and fixing to a shaft member, the wall panel is built at a construction site and adjacent wall panels are connected to each other, at least one of the left and right of the wall panel The column provided on the side is joined to the beam and the lower frame material so that the column wins, and the columns other than the column on the side are bonded to the beam and the column is applied to the lower frame material. Each wall panel is joined to win, and the wall panel is built in the construction site without the nailing and fixing of the structural face material to the side column, and the adjacent wall panels are connected to each other. After adjusting the structure of the building, Characterized by nailing fixed to a pillar of the serial side.

  In other words, the present invention provides a method in which, when a shaft member such as a pillar or a beam and a structural face material are integrally assembled at a factory, the structural face material is not nailed only to the side pillar, and the wall panel is attached. After building on site, the structural face material is nail-fixed to the side columns. As a result, even if a slight shift or deviation occurs when building a wall panel on site, it is possible to finely adjust the building and the street, thereby improving the workability.

  The wall panel construction method of the present invention is the step of pre-assembling the wall panel in the factory, leaving the side pillars and the structural face material in an unfixed state, and connecting the wall panels to each other on the site, Since the pillars and the structural surface material are fixed with nails, the advantage of short-time construction with a large integrated panel can be secured, and fine adjustments can be made at the site, improving the accuracy of installation and workability. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing a configuration example of a wall panel used in the construction method of the present invention, and FIG. 2 is a partial perspective view showing a state in which the wall panel is built.

  Main members constituting the illustrated wall panel 1 are a beam 2, a side column 3 a, an intermediate column 3 b, an intermediate column 4, a lower frame member 5, an opening lateral frame member 6, and an opening reinforcing frame 7. These are a shaft member such as, and a structural face material 8.

  The beam 2 and the column 3 (3a, 3b) are wall structural members, and are joined to the beam 2 so that the side column 3a wins. The beam 2 wins against the middle column 3b and the intermediate column 4. The lower frame member 5 is joined between the pillars 3, and the lower frame member 5 is superior to the inter-column 4 and the reinforcing frame 7 of the opening. And the structural surface material 8 which consists of a plywood etc. is stuck on the single side | surface or both surfaces of the frame | frame comprised by these shaft members. The structural face material 8 is fixed by nailing to a shaft member other than the side column 3a. The assembly and joining up to this point are carried out at the wall panel manufacturing factory.

  After the pre-assembled wall panel 1 is carried into the construction site, it is built as shown in FIG. Each wall panel 1 is erected on a foundation 9 or a lower-level beam (not shown) in an appropriate order, and the side column 3a and the beam 2 of the adjacent wall panel 1 are joined. This joining is performed by fitting the connecting hardware 10 attached in advance to the ends of the columns 3 and the beams 2 and the corresponding slits 11 and fixing them with connecting pins or bolts.

  According to the present invention, after all the wall panels 1 are installed for each floor, even when a minute mismatch occurs at the connection location between the adjacent wall panels 1, the structural face material 8 and the side pillars 3a Since it is not fixed, the structure and street of each wall panel 1 can be finely adjusted. Then, after this fine adjustment work, if the structural face material 8 is nail-fixed to the side column 3a, the rigidity of each wall panel 1 is sufficiently secured.

  Further, the wall panel 1 configured as described above is added to the column 3 because the lower end surface of the column 3 is directly fixed on the foundation 9 or the beam on the lower floor without interposing the lower frame material 5. A large vertical load can be smoothly transmitted to the foundation 9 and the beam.

It is a front view which shows the structural example of the wall panel used for this invention. It is a fragmentary perspective view which shows the built-in state of the said wall panel.
