To place. The ventilation packing 3 is provided with a ventilation groove 4 through which outside air can flow under the floor and a ventilation groove 5 that communicates with a later-described ventilation path provided on the wall side of the base 2 from under the floor. Next, the first-floor floor panel 6 is placed on the base 2 so that the end of the floor panel (the part where the crosspiece 6b that constitutes the floor panel 6 together with the face material 6a) is located in the upper surface middle part of the base 2. At the same time, a drift pin 8 is driven into and connected to the drift pin hole 7 provided across the crosspiece 6b and the base 2 at the end. The drift pin 8 is a pin for temporary fixing, as is the case with the drift pin described below, and is a kind of joint made of steel.

  When the base 2 and the first floor panel 6 are connected, a recess 9 is formed on the outside thereof, so that the floor side as the first embedding member manufactured according to the shape of the recess 9 so as to fill the recess The member 10 is removably inserted. After the floor-side member 10 is inserted into the recess 9, the first-floor wall panel 12 is placed on the ends of the floor-side member 10 and the first-floor floor panel 6, and the lower rail 12b of the wall panel, the floor-side member 10, and Drift pins 15 and 16 are driven and connected to drift pin holes 13 and 14 provided over the crosspiece 6b of the floor panel 6 from the inside of the panel. Reference numeral 17 denotes a face material affixed to the front surface of the floor-side member 10, reference numeral 12 a denotes a face material constituting the first floor wall panel 12, and reference numeral 12 c denotes an intermediate rail constituting the first floor wall panel 12. In FIG. 2, it seems that the drift pin 16 and the drift pin 8 interfere with each other, but actually, the position is shifted in the front-rear direction in FIG.

  Next, the second-floor floor panel 18 is placed on the first-floor wall panel 12 so that the end of the floor panel is located in the middle of the upper surface of the first-floor wall panel 12, and the crosspiece 18b and the first-floor 18 A drift pin 20 is driven into and connected to a drift pin hole 19 provided over the upper rail 12b of the wall panel 12 from the inside of the panel.

  When the first-floor wall panel 12 and the second-floor floor panel 18 are connected, a recess 21 is formed on the outer side thereof. As a second embedding member manufactured according to the shape of the recess 21 so as to fill the recess. The torso difference side member 22 is removably inserted. After fitting the trunk difference side member 22 into the recess 21, the drift pin 24 is driven into the drift pin hole 23 provided over the trunk difference side member 22 and the upper rail 12 b of the first floor wall panel 12 from the inside of the panel and connected. Next, the second floor wall panel 26 is placed on the end of the trunk difference side member 22 and the second floor floor panel 18, and is provided across the lower rail 26b of the wall panel, the trunk difference side member 22 and the floor panel 18 rail 18b. Drift pins 29 and 30 are driven into and connected to the drift pin holes 27 and 28 from the inside of the panel. Reference numeral 31 denotes a face material affixed to the front surface of the trunk difference side member 22, reference numeral 26 a denotes a face material constituting the second floor wall panel 26, and reference numeral 26 c denotes an intermediate rail constituting the second floor wall panel 26.

  Next, a girder 32 as a ventilation head connection is placed on the upper beam 26b of the second floor wall panel 26, and a drift pin 34 is inserted into the drift pin hole 33 provided between the beam 32 and the upper beam 26b of the second floor wall panel 26. Connect from the inside of the panel. In the above description, only the connection in the vertical direction has been described with respect to the connection of the wall panels 12, 26, etc., but it is of course possible to connect the horizontal direction at the same time and build them up simultaneously. In that case, the connection of the lateral wall panels is preferably about 4 or 5 stations. In this connection, a wall panel body in which about 4 or 5 plane wall panels are connected in advance and integrated may be raised and placed at once. In this way, the wall made up of the wall panels is raised over the entire periphery, and after processing with auxiliary materials (not shown) at the corners and corners of adjacent wall panels, purlins, rafters, etc. If you assemble and put a roof (not shown), it will be built up to the ridge. The building thus constructed is in a state before final construction such as nailing, but since the shearing force includes the drift pin, it can maintain a stable strength.

A similar ventilation path 43 is also provided on the 12b face material 12a side in the vertical direction.

  Further, an air passage 45 communicating with the air passage 43 of the first floor panel 12 is provided in the horizontal direction on the face member 31 side of the trunk difference side member 22, and the air passage 46 communicating with the air passage is in the vertical direction. An air passage 47 that faces the air passage and communicates with the air passage is provided facing the horizontal direction. In addition, an air passage 48 that communicates the air passage 47 of the trunk difference side member 22 and the inside of the panel is provided on the side material 26a side of the lower rail 26b of the second floor wall panel 26 so as to face the vertical direction. A similar air passage 49 is provided in the vertical direction on the wall side of the crosspiece 26b on the face material 26a side. An air passage 51 communicating with the air passage 49 is provided in the girder 32 so as to open to the outside and face the horizontal direction. Accordingly, the outside air is provided through the ventilation grooves 4 and 5 and the ventilation paths 36, 37, 38, 39, 40, 41, 43, 45, 46, 47, 48, 49, 51 provided so as to be continuously communicated with these members. It is possible to take the outside air under the floor and vent the outside air that has taken in along the wall from the bottom of the base 2 to the back of the ceiling above the girder 32, not only in the first floor wall panel 12 but also in the second floor wall panel 26. The effect of dehumidification can be great.

  An example of the floor side member 10 and the trunk difference side member 22 is as shown in FIGS. 6 (A) and 6 (B), and the length thereof is two series of wall panels 12 and 26 as can be seen from FIG. I'm on the minute. However, this is only an example, and the length can be set as appropriate. In addition, the air passages 38, 39, 40, 45, 46, and 47 provided in the floor side member 10 and the trunk side member 22 may be provided with an arbitrary number of them at predetermined intervals, or may be variously changed. Is possible. If such a member is used, even if there is a plan change at the time of extension and renovation, it can be dealt with as much as possible.

  That is, for example, as shown in FIG. 7, when a reconstructed window (waist high window) 57 formed between the luma wall panel 55 and the waist wall panel 56 is newly constructed, There is a case where it is desired to change the plan to open the waist wall panel 56 to a window (sweep window) 58 of the sweep opening as shown in FIG. Even in such a case, the floor side member 10 and the torso difference side member 22 that formed the ventilation path at the waist high window are removed from the recesses 9 and 21, and a floor side member 10 ′ without a ventilation path separately prepared, The trunk difference side member 22 ′ can be easily replaced by newly attaching it to the recesses 9 and 21. Since the trunk difference side member 22 ′ is provided with the rammer wall panel 55 at the upper part of the first floor, only the air passage communicating with the air passage 43 of the panel is provided. Of course, even when the sweep window 58 is changed to the waist high window 57, the floor side member 10 'without the air passage and the trunk side member 22' are replaced with the floor side member 10 with the air passage and the trunk side. The member 22 can be easily replaced. In addition, in this case, depending on the form of the waist high window, a floor side member and a torso difference side member having various ventilation paths prepared separately can be selected. In FIGS. 7 and 8, reference numeral 60 denotes a hammer receiving material, and 61 denotes a corner material.

  In the present embodiment, a two-story building is taken as an example, but a three-story or more building can be similarly constructed by repeating the connection of the floor panel, the body difference side member, and the wall panel if necessary. In the present embodiment, the first floor panel 6 is placed on the upper surface middle part of the base 2 so that the second floor panel 18 is located on the upper surface middle part of the first floor wall panel 12, and each is formed outside thereof.
