Fixed to Reference numeral 82 denotes a stupid hole through which the anchor bolt 3 passes through the vertical portion 81a of the L-shaped fixture, and reference numeral 4 denotes an anchor bolt 3.
A nut 83, which is fitted on the vertical portion 81a of the L-shaped fixing bracket, is fitted on the vertical portion 81a of the L-shaped fixing bracket. By adjusting the access, the L-shaped fixture 81 is adjusted to be parallel to the wall spacing with respect to the skeleton wall 1. 5 is a mortar,
After the L-shaped fixture 81 is positioned, it is filled and solidified between the L-shaped fixture 81 and the frame wall 1.

Reference numerals 84a and 84b denote support brackets attached to the left and right substantially symmetrical positions on the horizontal portion 81b of the L-shaped fixing bracket. Bolts penetrate through holes provided in the respective brackets, and are fastened and fixed by nuts. The through hole of the horizontal portion 81b of the fixing bracket is formed as a long hole 85 in the left and right direction, and the through hole of the support bracket 84 is formed as a long hole 86 in the front and rear direction. The final adjustment in the left-right direction is performed by the long hole 85 in the left-right direction. A bolt / nut 87 connects the L-shaped fixing bracket 81 and the supporting bracket 84. Reference numerals 88a and 88b denote pin through holes provided at the distal ends of the support brackets 84a and 84b, 89 denotes pins penetrated therethrough, and 90a and 90b denote lower side surfaces 2a ₁ and upper portions of the lower outer wall panel 2b of the upper outer wall panel 2a. a pin insertion hole provided at a predetermined position of the side surface 2b _2, which to the support bracket 84a, is inserted a pin 89 passing through the 84b, by the adhesive is filled in here, pin 89 is inserted Holes 90a, 9
It is fixed in 0b.

In this conventional example, a metal fitting for attaching the outer wall panel 2 to the body wall 1 is an L-shaped fixing metal 81 and a supporting metal 84.
It consists of two members, and the height is determined by the L-shaped fixing bracket 81
The positioning in the left-right direction and the front-rear direction is roughly adjusted by the above-mentioned fool hole 82 and the wall spacing adjusting bolt 83, and the final positioning is L-shaped fixing. The adjustment is made by adjusting the connection between the metal fitting 81 and the supporting metal fitting 84. The final positioning is performed by one of the support brackets 84b, the pins 89 are inserted and fixed in the pin insertion holes 90b of the lower outer wall panel 2b, and the upper support wall 84a is fixed by the other support bracket 84a. 2a is supported.

[Problems to be Solved by the Invention] The outer wall panels are mounted on the skeleton wall by sequentially stacking the upper panels on the lower panel, and each outer wall panel is attached to the skeleton wall in the front-rear direction and the left-right direction. In addition, it is necessary to perform positioning in three directions of vertical movement.

In the above conventional example, the one shown in FIG.
The position of the outer wall panel 2 is determined by moving the fool holes 75 of the L-shaped fixing brackets 71 in three directions of front, rear, left, right, and up and down. Although it is determined independently by determining the position of the inside of the nut 4, the positioning of the left and right and the height cannot be performed independently. That is, even if the positioning of the left and right is performed, the positioning of the height is performed next. Is often misplaced in the left and right positioning. Therefore, this positioning requires simultaneous adjustment in two directions. Furthermore, since the nut 4 is not tightened during this operation, there is a danger that the nut 4 may be rotated by a screw, and the position of the first positioning in the front-rear direction may be lost. The direction must be adjusted at the same time, which is a very time-consuming operation for lifting an external wall panel which is high and heavy.

In the conventional example shown in FIG. 8, the outer wall panel 2 is
The outer wall panel 2 is vertically positioned with respect to the anchor bolts 3 by the stagger of the vertical portion 81a of the L-shaped fixture 81 with respect to the anchor bolt 3. By the adjustment of the hole 82, the positioning is performed independently irrespective of the positioning in the left-right direction and the front-rear direction, but the left-right direction and the front-rear direction are the connection of the horizontal portion 81b of the L-shaped fixing bracket and the support bracket 84. It is positioned simultaneously by adjustment. In other words, the position of the support bracket 84 in the left-right direction is adjusted by moving and adjusting the bolt / nut 87 in the long hole 85 in the left-right direction of the horizontal portion 81b of the L-shaped fixing bracket. The position in the front-back direction is adjusted by moving and adjusting the support bracket 84 in the long hole 86 in the direction. Therefore, if both the left-right position and the front-rear position cannot be determined, the bolt / nut 87
However, the position cannot be tightened and fixed, and even if the position in the left-right direction is once determined, the position may shift during the adjustment in the front-back direction.

In this embodiment, compared to the embodiment shown in FIG. 7, there is no simultaneous adjustment in three directions, and the adjustment in the front-rear direction and the left-right direction is performed without affecting the adjustment in the vertical direction. Therefore, the adjustment work becomes easier, but since the support bracket 84 is attached to the horizontal portion 81b of the L-shaped fixing bracket 81, the wall spacing must be increased accordingly.

[Means for Solving the Problems] The present invention provides a method for adjusting the movement of the outer wall panel in the front-rear direction, the left-right direction, and the up-down direction when attaching the outer wall panel to the frame wall of the building. By moving and adjusting one direction at a time independently, the adjustment work is simplified, the positioning can be performed quickly and accurately, and the wall spacing does not increase.

An engaging portion is provided so that the movement of the wall spacing in the front-rear direction, the left-right direction, and the up-down direction when mounting the outer wall panel can be individually adjusted for each direction. Positioning can be performed for each direction without affecting other directions.

With respect to the engaging portion provided on the outer wall panel to be engaged with the adjustment bracket in each direction, the recesses for engagement with the wall space adjustment bracket are formed on the upper side surface and the lower side surface of the panel, and the front and rear side surfaces of the recess are left and right. Since the outer wall panel is provided so as to extend in parallel to the direction, if the wall space adjustment bracket is engaged therewith, the movement of the outer wall panel with respect to the skeleton wall is restricted in the front-rear direction, but in the vertical and horizontal directions. The movement of the outer wall panel is not restricted. Also, the engaging recess for the left and right adjustment bracket is formed on the surface facing the skeleton wall surface of the outer wall panel, and the left and right side surfaces of the recess are provided so as to extend in the vertical direction, so that the left and right direction adjustment bracket is provided there. When engaged, the movement of the outer wall panel with respect to the skeleton wall surface is restricted in the left-right direction, but is not restricted in the front-rear direction and the vertical direction. Further, the engaging concave portion for the height adjusting bracket is formed at a symmetrical position on the surface facing the skeleton wall surface of the outer wall panel, and the upper surface of the concave portion extends at the same height in the left-right direction. The movement is restricted in the vertical direction, but is not restricted in the front-rear direction and the left-right direction.

In another height adjusting nut of the present invention, the polygon of the polygonal nut is a polygon formed by combining two halves of two regular polygons having different numbers of sides, and a bolt is provided at an eccentric position of the combined diameter portion. Since the screw holes are provided, the distance to each side centering on the bolt is slightly different each time it is adjacent, so if the bolt is screwed and rotated, the slight rotation will be fine-tuned, Even if the outer wall panel is placed on the top, it is supported as it is without repeating the temporary fastening and loosening as in the conventional case.

According to another mounting structure of the outer wall panel of the present invention, the wall space adjusting metal fitting, the left and right adjusting metal fitting and the height adjusting metal fitting are separately mounted on the skeleton wall, and each of the outer wall panels at the corresponding positions is attached to the outer wall panel. An engaging recess is formed, and the wall spacing adjusting fitting engaging recess is formed on the upper and lower side surfaces of the outer wall panel so that the front and rear side surfaces of the recess extend in the left-right direction in parallel. Movement in the left-right direction and up-down direction is free even if the wall spacing is set, and the left-right adjustment metal fitting recess is formed so that the left and right sides of the recess extend in the vertical direction on the surface facing the skeleton wall surface. Therefore, even if the outer wall panel is positioned in the left-right direction, the outer wall panel is free to move in the front-rear direction and the up-down direction.
Since the upper surface of the recess is formed at the same height in the left and right direction on the surface facing the skeleton wall, it is free to move in the front and rear direction and left and right direction even if the outer wall panel is positioned in the vertical direction It is. Therefore, the adjustment operation in the three directions of front, rear, left, right, and up and down can be adjusted without affecting the other direction even if the operation is performed individually in one direction, and reliable and accurate adjustment can be performed.

Further, according to this mounting structure, since each adjustment fitting has only one adjustment function in one direction, a combination of two fittings is required to provide the adjustment function in two directions as shown in the conventional example of FIG. Therefore, the present invention can be implemented without increasing the wall spacing.

Furthermore, according to the mounting structure of the outer wall panel, in addition to the fact that accurate positioning of the above-mentioned respective adjustment brackets can be easily obtained, the recesses for engaging the respective adjustment brackets of the outer wall panel are all formed in a simple shape. Since the processing accuracy can be secured, most of the outer wall panel installation work, such as mounting of each adjustment bracket, can be performed without temporarily mounting the panel when installing the outer wall panel. The adjustment is advantageous, and the construction period can be shortened.

According to still another height adjusting nut of the present invention, the polygonal nut is a polygon obtained by combining halves of two regular polygons having different numbers of sides, and the eccentric position of the diameter portion where the halves are combined. Is provided with a bolt screw hole, so that the screw can be screwed to the anchor bolt and the outer wall panel can be supported on different sides so that the height can be adjusted. Even if you do not have to do the troublesome work of loosening and retightening the nut each time you move the bracket as in the case of the bracket, just turn the nut a little and there is no problem of insufficient tightening, and securely fix the outer wall panel It can be supported, so that adjustment and mounting operations can be performed more easily.
