The following problems have been pointed out with respect to the above-mentioned conventional CLT. That is, since cedar and cypress require a long period of time from planting to logging, CLT made from these is expensive to use as a building material for housing. In addition, since the specific weight of cedar and cypress is relatively large, the weight of CLT using cedar and cypress is also large. This makes it difficult to transport CLT to construction sites and handle it during construction, and it is necessary to connect adjacent CLTs with high-strength connecting metal fittings. In addition, the weight of the building becomes heavier and the burden on the foundation is also increased. growing. In addition, in CLT using lamina such as cedar, thorns are likely to be formed on the surface, and it is necessary to finish the inside of the building with wallpaper, tiles, etc., which further increases the construction cost and man-hours.

As shown in FIG. 8, the first CLT 11 and the third CLT 13 are bonded to the foundation by the bonding hardware. The main bodies of a plurality of anchors 61 are embedded in the concrete foundation 30 at predetermined intervals, and the first CLT 11 and the third CLT 13 are fixed to the anchors 61 by nuts 62 and stepped pins 63 which are fastening members. The anchor 61 is substantially attached to a male screw portion 61a formed in the middle of a portion protruding upward from the concrete foundation 30, a slightly smaller diameter shaft portion 61b extending above the male screw portion 61a, and an upper end portion of the shaft portion 61b. It has a pin hole 61c that penetrates in the horizontal direction. For the installation of the anchor 61, the anchor 61 can be accurately arranged by using the anchor holder proposed by the applicant of the present application in Japanese Patent No. 6137394 or Japanese Patent Application No. 2019-97420, and the first CLT 11 and the third CLT 13 can be installed. Installation can be done easily.

On the other hand, the first CLT 11 is provided with a through hole 11a through which the anchor 61 is inserted at a position corresponding to the anchor 61. Further, in the third CLT 13, a bottom hole (anchor hole) 13a into which the anchor 61 is inserted, a relief hole 13b for avoiding the nut 62, and a stepped hole (locking pin) 63 into which the stepped pin (locking pin) 63 is inserted are inserted. It has (locking hole) 13c. The stepped pin 63 described above has a large-diameter step portion 63a that fits into the stepped hole 13c of the third CLT 13, and a small-diameter step portion 63b that fits into the pin hole 61c of the anchor 61.

In assembling the first floor portion, the operator installs the airtight packing 65 on the upper surface of the concrete foundation 30, and then puts the first CLT 11 to be the floor plate 21 on the airtight packing 65 while inserting the anchor 61 into the through hole 11a. Place. Next, the operator firmly fixes the first CLT 11 to the concrete foundation 30 by fitting the washer 66 to the anchor 61 and fastening the two nuts 62 (that is, the double nuts for preventing loosening) screwed to the male screw portion 61a. do. After that, the operator places the third CLT 13 on the first CLT 11 while allowing the anchor 61 to enter the bottom hole 13a. Next, the operator drives the stepped pin 63 into the stepped hole 13c of the third CLT 13, inserts the small diameter step portion 63b of the stepped pin 63 into the pin hole 61c of the anchor 61, and firmly inserts the third CLT 13 onto the first CLT 11. Fix it.

As shown in FIG. 9, two adjacent third CLTs 13 are joined by a joining metal fitting. The metal joint has a connecting metal fitting 71 and two hexagonal coach screws (coach screws) 75. The connecting metal fitting 71 is a forged product of alloy steel, and as shown in FIG. 10, has a substantially U-shaped cross-sectional shape in which a pair of insertion piece portions 72, 73 are connected by the connecting piece portion 74. The insertion piece portions 72 and 73 have inclined surfaces 72a and 73a whose thickness decreases toward the tip on facing surfaces (inside the U-shape), and have a U-shape into which the shaft portion 75a of the hexagonal coach screw 75 enters. It has notches 72b and 73b. The connecting metal fitting 71 may be a press-molded steel plate instead of the forged product, which has a high manufacturing cost.

As shown in FIG. 11A, recesses 13d having substantially the same width as the width of the connecting metal fitting 71 are formed at predetermined intervals in the third CLT 13 (on the right side in FIG. 11A). Further, the hexagonal coach screw 75 is screwed into the opposite position (the position where the recess 13d is formed) of both third CLTs 13, but the insertion piece portion of the connecting metal fitting 71 is between the head 75b and the screwed surface. A gap S having a thickness of 72 or 73 is provided. In the gap S, it is preferable that the distance between the head portion 75b and the end surface of the third CLT 13 is narrower than the plate thickness of the connecting metal fitting 71. For example, when the plate thickness of the connecting metal fitting 71 is 5 mm, it is preferable that the distance between the head portion 75b and the end face of the third CLT 13 is 3 mm.

When connecting two third CLTs 13, the operator arranges these third CLTs 13 on the floor or the like as shown in FIG. 11A, and inserts the connecting metal fitting 71 into the recess 13d. Then, even if the two third CLTs 13 are slightly displaced, the tips of the insertion pieces 72 and 73 enter the gap S between the head portion 75b of the hexagonal coach screw 75 and the screwed surface. In this state, when the operator drives the connecting metal fitting 71 with a striking tool 77 such as a hammer, the head portion 75b of the hexagonal coach screw 75 facing the inclined surfaces 72a and 73a of the insertion pieces 72 and 73 is on the center side of the recess 13d. Driven towards. As a result, the two third CLTs 13 into which the hexagonal coach screw 75 is screwed move in a direction approaching each other together with the head 75b, and as shown in FIG. 11B, when the driving of the connecting metal fitting 71 is completed. Be concatenated. As described above, by making the distance between the head 75b and the end face of the third CLT 13 narrower than the plate thickness of the connecting metal fitting 71, the connecting metal fitting 71, the hexagonal coach screw 75 and the third CLT 13 can be firmly connected. can. After that, the worker drives the buried tree 78 into the recess 13d to finish the connecting work.

As shown in FIG. 12, the first CLT 11 which is the floor plate 23 on the second floor is connected to the third CLT 13 which is the wall on the first and second floors by bolts 81 of all screws. Through holes 11e through which bolts 81 are inserted are bored in the first CLT 11 at predetermined intervals, and bottomed holes 13e into which bolts 81 are inserted are bored in both third CLTs 13 at positions corresponding to the through holes 11e. ing.

In assembling the second floor portion, the operator applies an epoxy resin adhesive to the bolt 81 and pushes it into the bottom hole 13e of the third CLT 13 on the first floor side. Next, the operator places the first CLT 11 of the floor plate 23 on the third CLT 13 on the first floor side while inserting the bolt 81 into the through hole 11e. After that, the worker lowers the third CLT 13 on the second floor side while inserting the bolt 81 into the bottom hole 13e to finish the work.

As shown in FIG. 13, the second CLT 12 which becomes the roof 25 is connected to the third CLT 13 which becomes the wall of the second floor by the bolt 82 of the full screw. Bottom holes 12a into which bolts 82 are inserted are bored in the second CLT 12 at predetermined intervals, and bottom holes 13f are bored in the third CLT 13 at positions corresponding to the bottom holes 12a.

In assembling the roof portion, the operator applies an adhesive to the bolt 82 and pushes it into the bottom hole 13f of the third CLT 13 on the second floor side. Next, the operator lowers the second CLT 12 of the roof 25 onto the third CLT 13 while inserting the bolt 82 into the bottom hole 12a to finish the work.

As shown in FIG. 14, the window frame 50 of the curtain wall 47 on the second floor is held by the first CLT 11 (floor plate 23 on the second floor) and the second CLT 12 (roof 25). A holding groove 11f having a U-shaped cross section into which the lower edge of the window frame 50 is fitted is formed on the upper surface of the first CLT 11, and a locking groove 12b in which the upper edge of the window frame 50 is locked is formed at the end of the second CLT 12. It is formed.

Since the curtain wall 47 is not a structural bearing wall, it is attached at the construction completion stage (at the time of upper building) of the building 10. In mounting, the operator shall diagonally apply the lower edge of the curtain wall 47 to the holding groove 11f, and then stand it upright and fit the upper edge into the locking groove 12b, as shown by the alternate long and short dash line in FIG. Finish the installation with. The curtain wall 47 may be bonded to the first CLT 11 and the second CLT 12 by existing bonding means. The curtain wall 47 is not limited to the structure of the present embodiment, and may be, for example, a glass window of a sliding sash as a whole.

In the building of the present embodiment, since an inexpensive CLT made of paulownia is used, the construction cost can be reduced much (for example, about 1/10) as compared with the conventional construction method. In addition, since CLT made of paulownia is lightweight, it is possible to significantly reduce transportation costs and facilitate handling at construction sites. Furthermore, since the growth rate of paulownia is faster than that of cedar, etc., not only can the abandoned cultivated land be effectively used by using it in large quantities as a building material, but also the global warming can be achieved by absorbing carbon dioxide in the atmosphere. Can be suppressed. In addition, since paulownia is excellent in flame retardancy, humidity control, and heat insulation, the surface finishing treatment eliminates the need for interior work and exterior work, and can further reduce the construction cost. As described above, the present invention obtains various effects as described above by using paulownia, which has not been conventionally used as a structural material, as a structural material.

CLT1 is manufactured by alternately laminating and adhering the second plies 3 in which the lamina 6 to be used is arranged in the plate width direction. As a result, not only relatively short lamina 5 and 6 can be adopted, but also the second ply 3 is the inverted first ply 2 (that is, the first ply 2 and the second ply 3 are the same product). Will be. As a result, as compared with the CLT of the embodiment, the production and management of the first ply 2 (second ply 3) as a raw material becomes easier, and the cost and man-hours required for the production of the CLT 1 are reduced.
