The wooden frame building according to the embodiment of the present invention includes a plurality of building members 11 such as pillar materials, beam materials, wall materials, floor materials, and various sheet materials.

  The wooden frame building according to the embodiment of the present invention is formed by joining each building member 11 with a thermoplastic adhesive 12 having elasticity when solidified. In the specific example shown in FIG. 1, first, a stick-like hot melt adhesive 12 is set on a glue gun 13. The hot melt adhesive 12 heated to about 200 ° C. and melted is poured out from the discharge port 13a at the tip of the glue gun 13 and adhered to the joining surface of the building member 11 to join or superimpose other building members 2 They can be injected into the gap between the two building members 11 to join them. When the hot melt adhesive 12 cools and solidifies in about 30 seconds, the building members 11 are bonded to each other.

  Thus, since each building member 11 is couple | bonded with the thermoplastic adhesive 12 by heat sealing | fusion, use of a joining metal fitting, a screw, etc. can be reduced, construction is easy, and a construction period can be shortened. Moreover, each building member 11 can be peeled off by heating and melting the adhesive 12 from the wooden frame building of the embodiment of the present invention, and the wooden frame building can be dismantled. By heating the solidified thermoplastic pressure-sensitive adhesive 12 with a dedicated dryer, iron or the like, each building member 11 can be easily removed without breaking each building member 11. For this reason, at the time of renovation or rebuilding, each building member 11 can be removed and reused, and generation of waste materials can be suppressed.

  Moreover, the thermoplastic adhesive 12 can be reused as an adhesive by heating and solidifying again the thing adhering to each building member 11, and is economical. By heating and melting the pressure-sensitive adhesive 12 or solidifying it at room temperature, it is possible to easily disassemble and remove and install each building member, so that remodeling and rebuilding are easy. By reusing the building member 11, it can be easily relocated in a short construction period, and the wooden frame building can be handled as a movable property instead of a real estate.

  Since each building member 11 can be moved until the adhesive 12 is solidified, it is easy to adjust the mounting position of the building member 11. Further, unlike the case of fixing with nails, no nails are left on the surface of the building member 11 and the finish can be finished cleanly. Even after each building member 11 is attached, the mounting position of each building member 11 can be easily adjusted if the solidified adhesive 12 is heated and slightly melted. Further, by adjusting the mounting position of each building member 11 after the construction, it is possible to cope with the secular change of the building and the building member 11.

High effect. By using a rubber-based pressure-sensitive adhesive 12 such as a hot-melt pressure-sensitive adhesive, the gaps between the building members 11 can be filled with the pressure-sensitive adhesive 12 to improve airtightness, waterproofness, heat insulation, and soundproofing. . Moreover, each building member 11 can also be reinforced by injecting the adhesive 12 into a tear or a crack of each building member 11.

  By using the olefin-based hot melt adhesive 12 that is harmless to the human body, the construction work can be performed safely. If the pressure-sensitive adhesives 12 having different colors depending on the construction location are used, the construction work and the confirmation work after the construction can be facilitated by distinguishing the colors, and construction mistakes can be prevented. Also during the relocation, by assembling while confirming the color of the adhesive 12 attached to each building member 11, the mounting position of each building member 11 can be confirmed, and the work can be facilitated.

  When the thermoplastic adhesive 12 is poured out from the glue gun 13, the fluidity of the adhesive 12 can be adjusted by changing the temperature at which the adhesive 12 is heated. For example, by increasing the heating temperature, the adhesive 12 can be flown so as to be thin and wide, and by decreasing the heating temperature, the adhesive 12 can be attached so as to rise thickly. By changing the size and shape of the discharge port 13a of the glue gun 13, the manner in which the adhesive 12 flows out can be changed.
