It is preferable that the fixing position to the housing at the lower end of the fixing bracket can be adjusted in the height direction.

  The ALC panel mounting method according to the present invention is an ALC panel mounting method in which two or more ALC vertical wall panels installed between horizontal frames are mounted in the vertical direction of a wooden building frame from the outdoor side. The vertical wall panel has one anchor fitting embedded at the center in the width direction on the upper and lower sides, respectively, and the anchor fitting is open on the back side of the panel facing the housing, and is arranged in the lower stage. An upper end fixing bracket is attached to the upper end anchor bracket of the lower vertical wall panel, and the upper end of the upper end fixing bracket is fixed to the housing above the upper end of the lower vertical wall panel, and the upper stage At the lower end anchor bracket of the vertical wall panel, attach the lower end fixing bracket that has a lower end bifurcated in the width direction at the upper end, avoid the upper end of the upper end fixing mounting bracket at the branched lower end It is arranged on both sides in the width direction, and the branched lower end is arranged so that it appears in the gap provided between the upper end of the lower vertical wall panel and the lower end of the upper vertical wall panel. The gist is to fix the lower end of the frame to the housing.

  At this time, a horizontal plane portion having a surface parallel to the upper end surface of the lower vertical wall panel is provided in a portion positioned above the upper end of the lower vertical wall panel in the upper end fixing mounting bracket, and the horizontal plane portion is provided as the lower vertical wall panel. It is desirable that the upper end surface of the upper vertical wall panel is placed on the horizontal plane portion with a space therebetween.

  At this time, it is desirable that the vertical surface portion of the L-shaped bracket having the vertical surface portion and the horizontal surface portion be provided in contact with and fixed to the upper end of the upper end fixing mounting bracket, thereby providing the horizontal surface portion on the upper end fixing mounting bracket.

  Furthermore, it is desirable to fix the upper end of the upper end fixing bracket and the vertical surface portion of the L-shaped bracket to the housing with a common screw.

  According to the mounting structure of the ALC panel according to the present invention, the vertical wall panel is mounted in the horizontal direction by the mounting bracket via the anchor brackets embedded one by one in the center in the width direction on the upper end side and the lower end side of the vertical wall panel. Since it is installed between the housings and a gap is provided between the upper end of the lower vertical wall panel and the lower end of the upper vertical wall panel, each vertical wall panel has both ends in the width direction at the center in the width direction as fulcrums. It can be moved up and down, and is attached to the frame of a wooden building so as to be locked by interlayer deformation.

  In such a configuration, since the upper end of the upper end fixing mounting bracket attached to the upper end side anchor bracket embedded in the lower vertical wall panel is fixed to the housing above the upper end of the lower vertical wall panel, the lower vertical wall Panel mounting work can be performed from the outdoor side. And, the lower end of the lower end fixing mounting bracket attached to the lower end side anchor bracket embedded in the upper vertical wall panel is branched in a forked manner in the width direction so as to avoid the upper end of the upper end fixing mounting bracket. It appears in the gap provided between the upper end of the lower vertical wall panel and the lower end of the upper vertical wall panel, and the lower end of the lower end fixing bracket is fixed to the housing at this part. The installation work of the upper vertical wall panel concerned can also be performed from the outdoor side. Therefore, all the installation work of the vertical wall panel which attaches two or more to the up-down direction of the frame of a wooden building can be performed from the outdoors. Compared to buildings with steel-framed frames, the number of columns is large, and in wooden buildings where braces and studs are frequently used, vertical wall panels can be installed without being disturbed by columns and braces. Excellent.

When the horizontal plane portion on which the lower end is placed is provided, it is easy to position the upper vertical wall panel, and it is easy to set a gap of a size necessary for the work of attaching the lower end of the upper vertical wall panel to the housing.

  Then, at this time, if the vertical surface portion of the L-shaped bracket having the vertical surface portion and the horizontal surface portion is abutted and fixed to the upper end of the upper end fixing mounting bracket, and the horizontal surface portion is provided on the upper end fixing mounting bracket, Since the thickness of the portion for fixing the upper end fixing mounting bracket to the casing is increased by the thickness of the vertical surface portion of the L-shaped bracket, the mounting strength of the upper vertical wall panel to the casing is improved.

  Further, if the upper end of the upper end fixing bracket and the vertical surface portion of the L-shaped bracket are fixed to the casing by a common screw, the thickness of the portion for fixing the upper end fixing bracket to the casing is equal to that of the L-shaped bracket. Since it increases by the thickness of the vertical surface portion, the mounting strength of the upper vertical wall panel to the housing is improved.

  And either one of the screw insertion hole of the upper end fixing mounting metal fitting for inserting the common screw or the screw insertion hole of the L-shaped metal fitting is constituted by a long elongated hole in the vertical direction, and the height of the horizontal surface portion of the L-shaped metal fitting If the position can be adjusted, errors such as vertical wall panel manufacturing errors and mounting errors can be absorbed by adjusting the height of the horizontal plane, which improves the accuracy of the vertical wall panel mounting position. In addition, it is possible to reliably provide a gap having a size required for the work of attaching the lower end of the upper vertical wall panel to the housing.

  Further, the upper end fixing bracket is fixed to the beam using a single screw that does not pass through the L-shaped bracket, the screw insertion hole for inserting the single screw is a countersink, and the single screw is a countersunk screw Then, even if the position of the screw insertion hole for inserting the single screw of the upper end fixing mounting bracket overlaps the mounting position of the vertical surface portion of the L-shaped bracket, the single screw obstructs the mounting of the vertical surface portion of the L-shaped bracket. Therefore, the L-shaped bracket is securely attached to the upper end fixing bracket.

  The lower end fixing bracket is fixed to the lower end anchor bracket of the upper vertical wall panel by using bolts, and the bolt insertion hole for inserting the bolt of the lower end fixing bracket is formed by a long slot in the vertical direction. If the fixing position to the housing at the lower end of the fixing bracket can be adjusted in the height direction, errors such as manufacturing errors and mounting errors of the vertical wall panel can be transferred to the lower end anchor bracket of the lower end fixing bracket. Since it can be absorbed by adjusting the mounting position, the lower end of the lower end fixing mounting bracket can be securely fixed to the housing by a gap provided between the upper end of the lower vertical wall panel and the lower end of the upper vertical wall panel.

Is easier to set. In addition, the horizontal plane portion serves as a weight receiver for the upper vertical wall panel 10b, and thereby the weight of the upper vertical wall panel 10b on the lower end side anchor fitting 16b of the upper vertical wall panel 10b can be suppressed to be small. If there is no particular problem in the positioning of the upper vertical wall panel 10b and the operation of attaching the lower end of the upper vertical wall panel 10b to the housing, such a horizontal plane portion may not be provided.

  The horizontal surface portion is provided by abutting and fixing the vertical surface portion 32 of the L-shaped bracket 30 having the vertical surface portion 32 and the horizontal surface portion 34 to the upper end of the upper end fixing mounting bracket 40. Since the thickness of the portion for fixing the fixing bracket 40 to the casing increases, the effect of improving the mounting strength of the upper vertical wall panel 10b to the casing can be obtained. In addition, since the upper end of the upper end fixing bracket 40 and the vertical surface portion 32 of the L-shaped bracket 30 are fixed to the casing by a common screw 54, the thickness of the portion for fixing the upper end fixing bracket 40 to the casing is L-shaped. By increasing the thickness of the vertical surface portion 32 of the metal fitting 30, the effect of improving the attachment strength of the upper vertical wall panel 10 b to the housing can be obtained.

  The height position of the horizontal plane portion can be adjusted by the common screw insertion hole 46b of the upper end fixing mounting bracket 40 constituted by a long hole. For example, even if the vertical wall panel 10 has a manufacturing error or an installation error of the vertical wall panel 10, the error can be absorbed by adjusting the height position of the horizontal plane portion. That is, the accuracy of the mounting position of the upper vertical wall panel 10b can be increased, and the gap S2 having a size necessary for the mounting work on the lower end of the upper vertical wall panel 10b can be reliably provided. The height position of the horizontal surface portion can also be adjusted by configuring the common screw insertion hole 32a of the vertical surface portion 32 of the L-shaped bracket 30 with a long hole. If factors such as manufacturing errors of the vertical wall panel 10 are small and adjustment of the height position of the horizontal plane portion is not necessary, the common screw insertion holes 46b and 32a may not be configured as long holes.

  The fixing position of the lower end fixing bracket 20 to the housing at the lower end can be adjusted by the bolt insertion hole 22a of the lower end fixing bracket 20 constituted by a long hole. Thereby, the manufacturing error etc. of the vertical wall panel 10 etc. can be absorbed similarly to the meaning which adjusts the height position of a horizontal surface part. In order to perform all the installation work of the vertical wall panel 10 from the outdoors, the lower end of the lower end fixing bracket 20 is fixed with a gap S2 provided between the upper end of the lower vertical wall panel 10a and the lower end of the upper vertical wall panel 10b. By having such an adjustment mechanism, it is possible to reliably fix the lower end of the lower end fixing mounting bracket 20 to the housing with this gap S2. If factors such as manufacturing errors of the vertical wall panel 10 are small and adjustment of the fixed position is not necessary, the bolt insertion hole 22a may not be configured as a long hole.

  The reason why the single screw 54 is a countersunk screw and the screw insertion hole 46a through which this screw 54 is inserted is the countersunk hole is that the position of the screw insertion hole 46a through which the single screw 54 of the upper end fixing mounting bracket 40 is inserted is L. This is to prevent the single screw 54 from interfering with the attachment of the vertical surface portion 32 of the L-shaped bracket 30 even if it overlaps the mounting position of the vertical surface portion 32 of the L-shaped bracket 30. As long as the vertical surface portion 32 comes into contact, the countersunk head screw and the countersunk hole may not be provided.

  Although FIG. 1 shows an example in which two panels are mounted in the vertical direction, the present invention is applicable to a case where three or more vertical wall panels 10 are mounted in the vertical direction, and can be applied to a building having three or more floors. Of course.

  In FIG. 3C, a pair of screw insertion holes 46a formed at both ends in the width direction at the center in the length direction of the step surface portion 46 as screw insertion holes for fixing the upper end fixing mounting bracket 40 to the beam 2a. , 46a and a pair of common screw insertion holes 46b, 46b formed on the upper side in the length direction than the pair of screw insertion holes 46a, 46a, for example, if there is no problem in terms of mounting strength. It is also possible to omit the pair of screw insertion holes 46a and 46a at the center in the length direction as only the pair of common screw insertion holes 46b and 46b.
