(3) Example An example of the construction side body according to the present invention will be described with reference to the drawings.

(First Embodiment) FIGS. 1 to 7 show a construction side body according to one embodiment (first embodiment). That is, FIG. 1 shows the entire configuration, and FIGS. 2 to 7 show the partial configuration. In this embodiment, a mode by pin connection is adopted.

FIG. 1 shows the overall structure of a stacked formwork, in which a pair of side bodies A having a constant thickness and a rectangular flat plate-like side plate 1 as a main body are spaced apart from each other by a predetermined space with concrete placing space. And each side body A has another side body B
Are placed next to each other. In each side body A, two columns 2 are vertically fixed outside the side body 1, and the two opposing side bodies A are fixed and held by tie rods (separators) 6.

FIG. 2 shows an exploded configuration of a main part of the side body A. As shown in FIG.
An engaging tool 4 composed of an engaging concave tool 41 and an engaging convex tool 42 to be joined is fixedly provided, and is fixed by the connecting tool 3. That is, the support 2 has a rectangular hollow body 21 having a square pillar shape. The lower end of the column 2, that is, the column leg, forms an engagement recess 41 with the hollow portion 21, and the upper end of the column 2, that is, the column head, engages with a projection that is firmly fitted and fixed to the hollow portion 21. The projection 42 is formed. The engaging protrusion 42 is inserted into the engaging recess 41.

The connecting tool 3 includes a connecting rod 31 having a square connecting head 301 and a tapered connecting rod 31, and a connecting wedge 30 inserted through a connecting wedge hole 33 formed through the connecting rod 31. .

A connection penetration hole through which the connection rod 31 of the connection tool 3 can penetrate at a position corresponding to each of the engagement recess 41 and the engagement protrusion 42.
After the engaging members 41 and 42 are fitted with each other, the connecting rod 31 is inserted into the connecting penetration hole 32 to prevent the engaging members 41 and 42 from being pulled out.
Is penetrated. The connecting rod 31 is provided with a connecting wedge hole 33 through which the connecting wedge 30 is inserted, and a connecting head 301 of the head of the connecting rod 31 is provided.

In addition, a tie rod hole 61 is provided at the upper end of the column 2 to maintain the space between the opposing side plates 1 and prevent the column 2 from collapsing, and the tie rod 6 is inserted into the tie rod hole 61 in a penetrating manner. Each of the tie rods 6 is tightened by a tie rod tightening tool 62 attached to a screw portion screwed at both ends. At the center of the column 2, one or a plurality of horizontal beam supports 51 for mounting the horizontal beam 5 are provided.
The purpose of the crosspiece 5 is to use it as a reinforcing beam for the side plate 1 because the side plate 1 is deformed by the lateral pressure of concrete when the side surface of the side plate 1 is thin. For this reason, the presence or absence of the cross bar 5 is determined by the relationship between the size and thickness of the side plate 1 and the support 2, and the cross bar 5 can be omitted if the number of the support 2 is larger than the side plate 1.

Basically, as the manufacture of the side body A, the column 2 is located at a position of a quarter of the width of the side plate 1 from both ends of the side plate 1.
Is fixed to the outer surface of the two side bodies 1 as shown in FIG.

The support 2 and other members are preferably selected from light metals such as steel and aluminum, synthetic resins, wood, concrete, and the like, but other construction materials may be used as appropriate if possible in terms of production and use.

Further, the entire side plate 1 and the support 2 may be integrally formed of the above-described construction material, or only the support 2 and the crosspiece 5 may be integrally formed. At this time, the horizontal crosspiece 5 with the adjacent side body B may be made of a different material. In any case, various combinations are possible according to the purpose of the site.

Next, the construction method will be described.

First, build the foundation for mounting the building profile. An engaging tool 4 that can be fitted to the side column 2 is installed on the foundation. Thereafter, the side body for construction is installed on the foundation by engaging the engaging member 4 with the engaging member 4 embedded in the foundation. After installation, the connecting rod 31 of the connecting tool 3 penetrates the penetration hole 32 as described above, and thereafter the connecting wedge 30 for preventing the engaging tool 4 from being detached is driven in.

Next, the tie rods 6 penetrate into the tie rod holes 61 of the columns 2 of the side plates 1 installed opposite to each other, and maintain the interval between the side plates 1 according to the designed wall thickness.
Tightened by 62. Thereafter, the horizontal crosspiece 5 is installed as needed. If there is a gap between the crosspiece 5 and the side plate 1 depending on the cross-sectional shape of the support 2 by the thickness of the flange of the support 2, an insert material such as a wedge, that is, a width stop of the crosspiece.
52 should be provided. In some cases, a long horizontal crosspiece width stopper 52 is provided between the side bodies A and B.

Next, the column 2 of the second side wall is aligned with the column 2 of the first side wall, and the engaging recess 41 is fitted to the engaging convex 42 of the first side wall. This fitting operation is easily performed by aligning the phases of the columns 2.

 Thereafter, the above-described order is repeatedly performed.

In addition, the engaging unevenness tools 41, 42 provided at the upper and lower ends of the support
Are not necessarily arranged as shown in the figure, but may be arranged in reverse.

Further, the lateral joining of the side members may be performed by ordinary means without using the cross bar 5.

When there is distortion in the wall body formed by stacking the side bodies, the connecting wedge 30 is removed and the connecting tool 3 is inserted into the penetration hole.
32, the connection between the engaging concave tool 41 and the engaging convex tool 42 is released, and all or a corresponding side body is removed, and a new side body must be used. The part is repaired, and the wall is constructed by stacking the side again.

 FIG. 12 shows another insertion means.

In the construction side body shown in FIG.
An engaging concave portion 41 of a square frame is fixedly provided at the upper end of the supporting member 2, and a column 2 having an engaging convexity member 42 is fixed below the engaging concave portion 41. The front wall plate 41 'of the engaging recess 41 is inclined downward,
The inner space forms a connection penetration hole 32. In the side body D in the left half from the center in the figure, the side plate 1 is used as a decorative material, and there are an engaging tool 4, a support 2, and a tie rod 6 on the side where concrete is cast. Becomes The right half side body E is mainly used as a mold, and at this time, unlike the above, the engaging member 4, the support 2, the tie rod 6, and the side plate 1 are not filled.

12 (b), (c) and (d) show another embodiment of the engaging member 4 of the side bodies A and B. The side plate 1, the support 2 and the tie rod 6 are not different from the above in configuration, function and purpose, but the function of the engaging recess 41 is slightly different.

That is, in the figures (b) and (c), the front wall plate 41 'of the engaging recess 41 is elastically deformed. Engaging projection
When the engaging member 42 is fitted into the engaging recess 41 of the side surface member B, the engaging convex member 42 is elastically deformed by an amount of protrusion of e and engaged. After the engagement, the front wall plate 41 'of the engagement recess 41 returns to its original position due to elastic deformation. For this reason, the side body A is formed due to the projection 42 'of the engaging projection.
Does not peel off from the side body B.

The front wall plate 41 'of the engaging recess 41 shown in FIG. 12 (d) has a material or thickness that does not deform elastically.

In FIG. 12 (b), since the front wall plate 41 'is inclined inward, it does not come off even if a tensile force is applied to the engaging projection 42 after fitting. If the engaging recess is filled with mortar or the like to increase the restraining force, the restraining force is further increased. Since the front wall plate 41 'in FIG. 12 (c) has no restraining force against the tensile stress of the engaging projection 42, it is necessary to apply the restraining force from outside. Therefore, a construction method in which the side plate is used for makeup is preferable.

FIGS. 12 (e) and 12 (f) are cross-sectional plan views showing the fixed state of the side plate and the column, and FIG. 12 (e) shows the side end of the column expanded and embedded in the side plate. That is, in the dovetailed state, the end on the side of the pillar is L-shaped in FIG. 3F, and the groove in the side plate also corresponds to this. As described above, the side end of the column is freely changed depending on the use of the side body. This joining method applies to all of the present application.
