JP 2002-294880 A Japanese Patent Laid-Open No. 11-62082

However, in general wooden framed buildings such as those described in Patent Documents 1 and 2, when renovating or rebuilding, the building member is removed while being broken, so the removed building member cannot be reused. There was a problem that a large amount of waste material was generated.
Moreover, since a nail mark remains in a building member once used in a general wooden frame building, there is a problem that when it is reused, it does not look good when reused.

  The present invention has been made paying attention to such a problem, and it is easy to dismantle and remove building members, and the generation of waste materials can be suppressed by reusing the building members. It aims to provide a wooden building structure that can be finished.

  In order to achieve the above object, a wooden building structure according to the present invention has a frame and a face material, and the frame is located at a position constituting a wall or floor of the wooden building, on the indoor side and on the outdoor side. The indoor side end surface and the outdoor side end surface around the opening are parallel to each other, and are located at intermediate positions away from the outer edge and the inner edge of the indoor side end surface or the outdoor side end surface. An annular ridge or an annular groove surrounding the opening; and the face member has a fitting groove or a fitting ridge that fits the annular ridge or the annular groove; A thermoplastic adhesive having elasticity when solidified is sandwiched between the annular groove and the fitting groove or the fitting protrusion is fitted with the annular protrusion or the annular groove. It is characterized by blocking the opening and forming a wall or floor.

  The wooden building structure according to the present invention combines the frame and the face material by thermal fusion with a thermoplastic adhesive, so the use of joint fittings and screws can be reduced, construction is easy, and the construction period is shortened. can do. Further, when removing the face material, the solidified thermoplastic pressure-sensitive adhesive can be easily removed without breaking the face material and the frame by heating with a dedicated dryer or iron. For this reason, at the time of renovation or rebuilding, the face material can be removed and reused, and the generation of waste material can be suppressed. In this way, by heating and melting the pressure-sensitive adhesive or solidifying it at room temperature, the face material can be easily removed and attached, so that remodeling and rebuilding are easy. When a thermoplastic adhesive is provided in an annular shape so as to surround the opening between the annular ridge or annular groove and the fitting groove or fitting ridge, it is airtight at the fitting position between the frame and the face material. Can keep sex.

Moreover, since a face material can be moved until an adhesive solidifies, adjustment of the attachment position of a face material is easy. Furthermore, unlike the case of fixing with a nail, a nail mark does not remain on the surface of the face material, and it can be finished cleanly.
Since an adhesive having elasticity when solidified is used, when the adhesive is solidified, the adhesive becomes a cushioning material, and vibrations are not easily transmitted between the face material and the frame, and the seismic isolation effect is high. The thermoplastic adhesive is preferably made of a rubber-based adhesive such as a hot melt adhesive. By filling the gap between the face material and the frame with an adhesive, airtightness, waterproofness, heat insulation, and soundproofing can be improved. At the same time, the face material or the frame can be reinforced by injecting an adhesive into a crack or a crack of the face material or the frame.

In the wooden building structure according to the present invention, it is preferable that the frame is formed by combining four square members in a square shape at the corners, and sandwiching a thermoplastic adhesive having elasticity when solidified at a joint portion. .
In this configuration, since the frame can be moved until the adhesive is solidified, it is easy to adjust the mounting position of the frame. Furthermore, unlike the case of fixing with a nail, a nail mark does not remain on the surface of the frame, and it can be finished neatly. By heating and melting the pressure-sensitive adhesive or solidifying it at room temperature, the framework can be easily disassembled or reconstructed into square bars, so that remodeling and rebuilding are easy. In addition, since an adhesive having elasticity when solidified is used, when the adhesive is solidified, the adhesive becomes a cushioning material and vibrations are not easily transmitted through the frame, and the seismic isolation effect is high. The backlash of the frame can be suppressed by the adhesive. The square bar may be flat or prismatic.

  In the wooden building structure according to the present invention, the frame is composed of a base, a horizontal member, and two pillars, and the base and the horizontal member are 1 along the length direction on the inner side facing the opening. An end protrusion or end that has one or more holding grooves or protrusions, and each column is fitted to the end so as to be movable along the length direction with respect to the holding grooves or the protrusions. A thermoplastic adhesive that has a groove and has elasticity when solidified may be sandwiched between the holding groove or the holding protrusion and the end protrusion or the end groove.

  In this configuration, the pillar can be attached to the base and the horizontal member by being shifted from the ends of the base and the horizontal member. Alternatively, the horizontal member may be placed on the pillar after the pillar is placed on the base. Since the column or the horizontal member can be moved until the adhesive is solidified, it is easy to adjust the mounting position of the column or the horizontal member. Furthermore, unlike the case of fixing with a nail, a nail mark does not remain on the surface of the frame, and it can be finished neatly. In addition, since an adhesive that has elasticity when solidified is used, when the adhesive is solidified, the adhesive acts as a cushioning material, making it difficult for vibration to be transmitted between the column and the base or horizontal member. High effect. The backlash between the column and the base or the horizontal member can be suppressed by the adhesive.

In the wooden building structure according to the present invention, the metal plate has a metal plate, the metal plate has two foldable ends, and is between the frame and the face material, between the foundation and the column, or It may be sandwiched between the horizontal member and the column in contact with the adhesive, and may be protruded to the outside so that the two end portions can be grasped.

Further, the face material, the horizontal member, and the like can be easily removed by bending the end projecting to the outside of the metal plate so as to be easily grasped and grasping and pulling. In addition, the edge part which protruded the exterior of the metal plate does not get in the way by keeping it along a foundation, a pillar, a horizontal member, etc. except at the time of dismantling. The protruding end portions may have fixing portions on opposite surfaces. In this case, the metal plate can enhance the coupling force between the frame and the face material, the base and the pillar, or the horizontal member and the pillar. The fixing portion is preferably made of the adhesive that can be attached to the frame and the face material, the base and the pillar, or the horizontal member and the pillar, respectively.

  According to the present invention, it is possible to provide a wooden building structure that is easy to dismantle and remove building members, can suppress the generation of waste materials by reusing building members, and can be finished cleanly when reused. Can do.
