The horizontal bar fitting portions 16 and 17
Is formed.

In constructing the outer wall of the building, first, the threaded portion 1a of the separator A embedded in the frame 3 of the building is used.
Then, the threaded portions 8 of the net support members C1 to C4 are screwed and attached.

At this time, the net supports C1 to C4 are rotated to move the net supports C1 to C4 in a direction along the shaft foot 1, and the net fixing plates 9a to 9d are evenly distributed on the respective vertical streaks 6. Adjust so that it abuts. Then, the holding metal fitting 10 is fitted to the vertical streak 6, and the net fixing plate 9 a is screwed into the net fixing plate 9 a while being pierced by the piercing screw 11 and fixed.
Thus, the reinforcing nets B1 to B4 are supported and established at predetermined positions.

Next, the ceramic porcelain plate D having the above structure is attached to the outer surfaces of the reinforcing bars B1 to B4,
While being fitted with the desired mounting method such as a break joint or a potato joint. As a result, an outer wall frame E (FIG. 4) formed by mounting a large number of ceramic ceramic plates D on the reinforced nets B1 to B4 is established.

Then, the mortar is filled on the back side of the outer wall frame E to form a mortar layer F for embedding the horizontal protrusions 14 and 15 of the reinforcing steel nets B1 to B4 together with the horizontal streak fitting portions 16 and 17 of the ceramic porcelain D. And build the desired outer wall.

The upper and lower rebar nets may not be able to face the vertical rebars fixed to the net fixing plates 9a to 9d due to deformation of the rebar nets or unevenness of the frame outer surface 3a. .

In such a case, after fixing one of the two opposing vertical streaks to the net fixing plate, the other vertical streak is fixed to the net fixing plate so as to face the one vertical streak. It is necessary to fix them while pressing and deforming them, which is troublesome. Therefore, a temporary fixing tool for temporarily fixing the vertical bars of the two rebar nets is used so that the vertical bars are opposed to each other until the vertical bars are fixed to the net fixing plate.

The temporary fixing device F includes an upper side portion 19a and a lower side portion 19a.
3B, three temporary fixing pieces 20 to 22 are cut out and formed on a rectangular substrate 19 in which the horizontal streak fitting recesses 18 are formed. The temporary fixing pieces 20 to 22 are arranged at intervals 23 that sandwich the longitudinal bars 6 such that the lower ends of the longitudinal bars 6 of the upper reinforcing net and the upper ends of the longitudinal bars 6 of the lower reinforcing net face each other. It is formed alternately before and after the vertical streaks 6. More specifically, a position where the upper temporary fixing piece 20 is in contact with the lower end of the longitudinal bar 6 of the upper reinforcing net from the rear side,
The middle temporary fixing piece 21 is located at a position where it comes into contact with the upper end of the vertical bar 6 of the lower reinforcing net from the front side, and the lower temporary fixing piece 22 is
It is formed at a position where it comes into contact with the vertical bar 6 of the lower reinforcing bar net from the rear side (FIGS. 7A and 7B).

The temporary fastener F is used as follows. As shown in FIG. 8, for example, the longitudinal bars 6 of the upper reinforcing net to be fixed to the net fixing plate 9a of the net support C1, and the longitudinal bars 6 of the lower reinforcing net facing the same.
The temporary fasteners F are respectively attached to the upper and lower vertical streaks 6, 6 arranged on the left and right of the vehicle. That is, the recesses 18 for fitting the horizontal stripes of the board 19 are fitted to the horizontal stripes 7 at the lowermost stage of the upper reinforcing net and the horizontal stripes 7 at the uppermost stage of the lower reinforcing net. The board 19 is sandwiched, and the lower end of the vertical bar 6 of the upper rebar net and the upper end of the lower vertical bar 6 are inserted between the temporary fixing pieces 20 to 22 of the temporary fixing tool F.

As a result, the vertical bars 6, 6 of the upper and lower reinforcing nets to be fixed to the net fixing plate 9a face each other. Further, the net support C1 is rotated and adjusted so that the net fixing plate 9a abuts on the vertical streaks 6,6. Then, the holding metal fittings 10 are respectively fitted to the respective vertical bars 6 of the upper and lower rebar nets to be fixed to the net fixing plate 9a and screwed into the net fixing plate 9a while piercing the net fixing plate 9a with piercing screws 11. 6 and 6 are net fixing plates 9
a.

FIGS. 9 and 10 show another embodiment of the net support. The net support members C5 shown in these figures are provided on the frame 24 having the outer surfaces 24a and 24b orthogonal to each other, and when reinforcing steel nets B5 and B6 having the same structure as the above-described reinforcing steel nets B1 to B4 are erected, Longitudinal streaks arranged 6,
6 is supported.

The net support member C5 is provided with a net fixing plate 25 having a size which abuts a part of each of the vertical bars 6, 6 of the reinforcing bar nets B5, B6 arranged on the left and right sides, and the vertical bar 6
And the holding metal fitting 10 for fixing the above.

The net fixing plate 25 is composed of reinforced nets B5, B
6 together with a part of the vertical streaks 6 and 6 arranged at the opposing outermost end, and has a size to contact the horizontal streaks 7 and 7 arranged above and below the longitudinal streaks 6 and 6. Further, both end portions of the net fixing plate 25 are bent so as to be parallel to the opposing reinforced nets B5 and B6, respectively.
The vertical stripes 6 and 6 are fixed to a and 25a by the holding metal fittings 10.

In the above description, an example was described in which the longitudinal bars of the reinforced net were fixed to the net fixing plate of the net support, but when the reinforced net was erected on the outer surface of the skeleton with the horizontal bars inside, the horizontal bars were fixed to the net. It may be fixed to a plate.
