Description

  The present invention relates to a method for constructing a plate wall in a wooden building, and more particularly, to a method for constructing a plate wall using a dropping plate method.

The dropping plate method is a construction method in which a groove is dug in the vertical direction on the opposing surfaces of two pillars, and a wall plate is dropped into the groove to form a wall surface of the building.
In this drop plate method, after the column is erected on the base, the end of the wall plate is inserted from the upper end of the column into the groove, and the wall plate is sequentially dropped onto the base along the groove to remove the plate wall. Form. In this type of dropping board method, it was necessary to build up the upper structure such as the roof and the second floor part by forming a board wall and then spanning a girder to the upper end of the column.

For this reason, the construction procedure of the wooden building is restricted, and it is not easy to shorten the construction period. In addition, there are disadvantages that the design is restricted. In addition, with the conventional drop plate method, when repairing or repairing the plate walls of a wooden building, it is necessary to remove the girders placed on the pillars. There is a problem of becoming.
Therefore, in the construction method described in Patent Document 1, the wall plate is divided into left and right members, the front ends of these members are respectively locked to the pillars, and the base ends are connected to a tree such as a metal ring joint. A technique has been proposed in which the joints are joined to each other by a joint.
Japanese Patent Laying-Open No. 2003-301542 (see FIGS. 9 and 4 of the drawings)

In the construction method described in the above-mentioned document, it is necessary to join the two divided wall plates with a metal ring joint, which is troublesome and costly, and there is a problem that the strength of the plate wall may be reduced. Further, the construction method described in this document also has a problem that the effective cross-sectional area of the column is reduced and the strength may be insufficient because a groove needs to be dug into the column.
The present invention has been made in view of the above problems, and it is possible to form a plate wall even after attaching a girder to the upper end of the column, and it is not necessary to dig a groove in the column, and it is sufficient with simple and low cost. It aims at providing the construction method of the board wall in the wooden building which can form the board wall which has special intensity | strength.

To achieve the above object, the invention according to claim 1 is a construction method of a plate wall in a wooden building in which a plurality of wall plates are sequentially dropped into a groove formed in a pillar to form a wall plate. A groove fitted to an end of the wall plate, a notch formed at one end of the groove and having a smaller width than the wall plate, and formed on a side wall of the groove adjacent to the notch, the wall plate A holding frame having a guide surface that guides the groove to the inside of the groove, and before or after the column is erected, the notch is located on the upper surface of the column so that the notch is positioned at the upper end. The method includes a step of attaching a holding frame and a step of fitting and dropping the wall plate into the groove from the notch after attaching a girder to the upper end of the pillar.
According to this method, since it is not necessary to form a groove on the side surface of the column, the strength of the column can be sufficiently maintained. In addition, since the wall plate can be fitted into the groove from the notch located at the upper end of the holding frame attached to the opposite surface of the column, the wall plate is formed after attaching the girder to the upper end of the column It can be easily repaired and repaired without restricting the construction procedure of the wooden building.
In the present invention, if the holding frame is manufactured in large quantities in advance and cut into the required length according to the length of the column, the holding frame is simply attached to the opposite surface of the column where the plate wall is to be formed at the construction site. Therefore, it is possible to prepare for the plate wall formation in a shorter time and at a lower cost than engraving and forming the groove.

In this case, as described in claim 2, after fitting the wall plate into the groove, a wedge is driven into a gap between an end portion of the wall plate and a bottom surface of the groove, and the wall plate is You may make it not move to a longitudinal direction between a pair of pillars. In this case, as described in claim 3, it is preferable that a vertical groove is formed at the end of the wall plate and the wedge is driven into the groove. By doing so, it becomes possible to drive the wedge even if the gap is small, and it is possible to firmly fix the wall plate between the columns by effectively utilizing the action of the wedge. It becomes possible.
According to a fourth aspect of the present invention, at the upper edge of the wall plate, one or a plurality of engaging portions are formed along the longitudinal direction of the wall plate, and the other wall plate located in the upper layer is formed. You may form the to-be-engaged part engaged with the said engaging part in a lower end edge.
By doing in this way, a highly strong wall board can be formed. Moreover, the board wall excellent in heat insulation can be formed without the clearance gap between wall boards.

Since the construction method of the present invention is configured as described above, the construction of the plate wall by the dropping plate method can be performed easily and at low cost. In addition, it is possible to form a plate wall even after attaching a girder to the upper end of the pillar, increasing the degree of freedom in the construction procedure of the wooden building, and facilitating shortening of the construction period.
Furthermore, even after completion of the wooden building, it is possible to easily repair or repair the plate wall without removing other members such as girders.
Moreover, since it is not necessary to dig a groove in the column and the cross-sectional area of the column does not decrease, a plate wall having sufficient strength can be formed.

DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view in which a part of a plate wall formed by the construction method of the present invention is cut away, and FIG. 2 is an enlarged perspective view of an upper end portion of one column of a pair of columns. It is.
As shown in FIG. 1, a plate wall 1 to which the construction method of the present invention is applied has a plurality of pillars 11, 11... The girder 12 is bridged and a plurality of wall plates 14 are sequentially stacked from the base 10 to the girder 12 between the pair of pillars 11 and 11.
On the opposing surfaces of the pair of pillars 11 and 11, holding frames 13 and 13 having a U-shaped cross section having a groove having a width substantially the same as the thickness of the wall plate 14 are attached, and a groove 13b of the holding frames 13 and 13 is attached. , 13b, the wall plate 14 fitted from above is dropped onto the base 10 sequentially.
The holding frames 13 and 13 may be formed of a woody material in the same manner as the pillar 11 or the wall plate 14, but may be formed of resin or metal.

  As shown in an enlarged view in FIG. 2, notches 13a and 13a are formed at the upper ends of the holding frames 13 and 13 by cutting off one of the two side walls forming the grooves 13b and 13b. By forming such notches 13a and 13a, the wall plate 14 can be fitted into the grooves 13b and 13b from the notches 13a and 13a even after the beam 12 is mounted on the pillars 11 and 11. It can be included.

FIG. 3 is a view for explaining a procedure when the wall plate 14 is inserted into the groove 13b, and is a cross-sectional view taken along the II direction in FIG.
As shown in FIG. 3A, the width h of the notch 13 a is formed to be smaller than the width H of the wall plate 14. The specific dimensions of the width H and the width h are, for example, when the width H of the wall plate 14 is 12 cm, the width h of the notch 13a is about 8 cm to 10 cm.
Thus, the width h of the notch 13a is made smaller than the width H of the wall plate 14 because the wall plate 14 fitted last in the groove 13b, that is, the wall located at the uppermost stage in the plate wall 1 is used. This is to prevent the plate 14 from easily falling off the holding frames 13 and 13. An arcuate or inclined guide surface 13d is formed at the upper end of one side wall of the groove 13b in which the notch 13a is formed, and the wall plate 14 inserted into the notch 13a is inserted into the groove 13b. I try to lead it smoothly.

When inserting the wall plate 14 into the groove 13b, first, as shown in FIG. 3 (a), with the wall plate 14 slightly tilted forward (operator side), both ends thereof are notched 13a, Align to 13a. And the wall board 14 is moved toward the holding frames 13 and 13 so that the both ends may be inserted into the notches 13a and 13a.
Next, the wall plate 14 is fitted into the grooves 13b and 13b while the wall plate 14 is raised in the direction of the arrow in FIG. Thereafter, the wall plate 14 is dropped along the grooves 13b and 13b, and is stacked on the other wall plate 14 which has been previously fitted.
In this way, the plate wall 1 is formed as shown in FIG. In the notches 13a and 13a, it is preferable to insert a buried wood 16 or the like after the plate wall 1 is formed.

FIG. 4 is an enlarged view for explaining a joint portion of the wall plates 14 and 14 in this embodiment.
On the lower end edge of the wall plate 14 fitted in the groove 13, a single convex portion 14 a is formed continuously from one end to the other end. Moreover, the upper end edge is formed with a concave portion 14b into which the convex portion 14a of another adjacent wall plate 14 is fitted.
As described above, the convex portions 14a and the concave portions 14b are formed on the respective wall plates 14, 14..., And when the wall plates 14, 14. By fitting into the concave portion 14b of the wall plate 14, the strength of the wall plate 1 composed of the wall plates 14, 14... Can be increased, and the surfaces of the plurality of wall plates 14, 14. By aligning the inside, the appearance of the wall plate 1 can also be improved. Moreover, the board wall 1 excellent in heat insulation can be formed without the clearance gap between wall boards.

The wall plates 14, 14... Are dimensioned to the exact length corresponding to the distance between the holding frames 13, 13 (the distance between the bottoms of the grooves 13 b, 13 b) in advance. Even after being fitted into the 13 grooves 13b, 13b, there is almost no movement in the longitudinal direction, and a good plate wall 1 can be constructed.
However, it is difficult to dimension the wall plates 14, 14... In an accurate length in advance, and the length of the wall plates 14, 14. Since it changes, it will eventually become a match with the site, and a great deal of labor and time will be spent preparing the wall plates 14, 14.
Further, when the length of the wall plate 14 is exactly the same as the distance between the holding frames 13 and 13, the end of the wall plate 14 is easily caught in the grooves 13b and 13b, and the wall plate 14 is dropped. Becomes difficult.

Therefore, in this embodiment, the wall plates 14, 14... Are roughly adjusted to the distance between the holding frames 13, 13 and preferably slightly shorter than the distance between the holding frames 13, 13.・ The dimensions are adjusted. This facilitates the preparation of the wall plates 14, 14... And prevents the wall plates 14 from being caught in the grooves 13b, 13b. In addition, the wedges 15 are driven into the gaps formed between the bottom surfaces of the grooves 13b, 13b of the holding frames 13, 13 and the end surfaces of the wall plates 14, 14,. The direction is not moved.
In this embodiment, as shown in FIG. 5, a vertical groove 14c in the vertical direction is formed at the ends of the wall plates 14, 14... And a wedge 15 is driven into the vertical groove 14c. By doing in this way, even when the gap between the bottom of the groove 13b of the holding frame 13 and the end of the wall plate 14 is small, the wedge 15 can be easily driven into the vertical groove 14c, and the wedge 15 The fastening effect by driving can be sufficiently obtained.
The wedge 15 may be driven into both ends of the wall plates 14, 14... But may be driven into either one. Further, the wall plate 14 (wall plate 14 positioned at the uppermost stage of the plate wall 1) that is finally fitted into the groove 13b is blocked by the girder 12 and cannot be driven by the wedge 15 from above, so that the wedge 13 can be driven from the notch 13a. It is good to insert in and to drive in the said clearance gap from the front side.

Although a preferred embodiment of the present invention has been described, the present invention is not limited to the above-described embodiment.
For example, in the above description, the convex portion 14a is formed on the lower end edge of the wall plate 14 and the concave portion 14b is formed on the upper end edge. However, the form of forming the convex portions 14a and 14b is not limited to this, and the upper end edge is formed. It is good also as what forms the convex part 14a and forms the recessed part 14b in a lower end edge. Moreover, it is good also as what forms the convex part 14a and the recessed part 14b with a fixed space | interval instead of forming continuously in a longitudinal direction.

  If the construction method of this invention is a wooden building which forms a board wall, it can apply widely regardless of the kind and magnitude | size.

It is the perspective view which applied to one Embodiment of the plate wall formed with the construction method of this invention, and fractured | ruptured the one part.
