Therefore, for the purpose of shortening the construction period and preventing peeling of the heat insulating material and deterioration of the heat insulating performance, the foam material-based formwork is arranged at positions on both sides of the base, and the length of the base is in the length direction of the base. A large number of connections were made in the direction, concrete was cast inside, and a concrete foundation was constructed, and the above-mentioned formwork was considered to be left for insulation even after the foundation was constructed. However, when the foam-based molds are connected to each other in the longitudinal direction of the foundation, it is expected that there will be a problem that the connecting portion is broken at the time of placing concrete because the strength of the connecting portion is particularly low. There was room for further improvement in this regard. Therefore, the present invention provides a basic heat-insulating formwork capable of preventing the connection portion from being damaged at the time of placing concrete by securing the strength of the connecting portion with another basic heat-insulating formwork.

Here, for convenience, a pair of base spacers 17, top spacers 18, and separators 19 have been described as being attached to the pair of basic heat-insulating molds 11,11. 13,1
A set of a base spacer 17, a top spacer 18, and a separator 19 is attached to each of the positions 3, 3,. Will be arranged so as to extend along. In this case, the foundation heat insulating molds 11 adjacent in the longitudinal direction of the foundation are connected to each other via one reinforcing member 13.

The concrete foundation 50 is constructed by placing concrete between the heat insulating base frames 11 assembled as described above. Then, even after the foundation where the concrete foundation 50 is hardened, the foundation heat-insulating molds 11, 11 which have become the concrete-casting molds are left for heat insulation. And the separator 19 is also left.

That is, as shown in FIG. 11, the constructed foundation is provided on both sides of the concrete foundation 50 whose shape is determined by the basic insulation forms 11, 11.
Is left attached, and the base spacer 17 and the separator 19 are joined to the reinforcing material 13 of the basic heat insulating mold 11 and are left in a state where the basic heat insulating molds 11 and 11 are connected to each other. Here, the base spacer 17
The inner clamping pieces 23, 23, which are a part thereof, and the base 21 therebetween are fixed to the concrete foundation 50 by adhering to the concrete foundation 50. In addition, the separator 19 is fixed to the concrete foundation 50 by embedding the intermediate member 35 in the concrete foundation 50.

The top spacer 18 is removed from the foundation at a necessary timing after the foundation is constructed. That is, after removing the nut member 47 from the anchor bolt 32, the anchor bolt 32 is pulled out from the anchor mounting hole 33, and the top spacer 18 is removed from the foundation. Of course, also in this state, the anchor bolt 32 is maintained in a state of being partially buried in the foundation and fixed.

According to the above-described embodiment, since the basic heat-insulating formwork 11 serves as a concrete-casting formwork and a heat-insulating material at the same time, the formwork is removed after the foundation is constructed and the heat-insulating material is further backed. As compared with the case, the labor can be greatly reduced and the construction period can be shortened. In addition, there is almost no waste material on site, saving resources. The base heat-insulating form 11 can be easily operated because the base material 12 is made of a foam material and is light.

Further, the reinforcing material 13 is attached to the basic heat insulating form 11.
By attaching a lath net to the reinforcing member 13, mortar as an exterior finishing material can be applied, peeling and strength problems can be cleared, and the reliability of the exterior finish can be improved. .

In addition, the basic heat-insulating form 11 is provided with reinforcing materials 1 on other basic heat-insulating forms 11 adjacent in the longitudinal direction of the foundation.
3, so that the strength of the connecting portion can be ensured. Therefore, it is possible to prevent the basic heat-insulating formwork 11 from damaging a connection portion with another basic heat-insulating formwork 11 at the time of placing concrete.

In the connecting portion between the basic heat insulating molds 11, 11, a cutout portion 14 a formed at the end of the basic heat insulating form 11 in the longitudinal direction of the basic heat insulating form 11 is formed. In the groove 14 formed by the notch 14a,
Since the reinforcing member 13 is disposed, the amount of protrusion of the reinforcing member 13 from the base material in the thickness direction of the foundation can be suppressed. Therefore, since it does not get caught on the reinforcing member 13 and does not cause peeling, a favorable state can be maintained even after the foundation is constructed.

Further, the notches 14a, 14a of the substrate 12
The grooves 14 are formed at positions between them, and the reinforcing members 13 are arranged in these grooves 14,
The base heat-insulating formwork 11 is reinforced not only at the connection portion with the other heat-insulation formwork 11 but also at the intermediate portion.
Therefore, it is possible to prevent the middle portion of the basic heat-insulating form 11 from being damaged at the time of placing concrete.

In addition, the base spacer 17 is fixed to a predetermined position of the base base B with concrete nails or the like so that the positions of the holding portions 22, 22 are at desired positions. The basic heat insulation formwork 11, 11 can be arranged at a desired position by being fitted to the, and positioning becomes easy.

Since the base spacer 17 and the separator 19 are left in a state of being joined to the reinforcing material 13 of the basic heat insulating mold 11 even after the foundation is constructed, the basic heat insulating mold 1
1 is fixed to the concrete foundation 50 by the adhesive force to the concrete foundation 50 and the coupling force of the base spacer 17 and the separator 19 to another foundation heat-insulating formwork 11 and the like. Therefore, peeling of the basic heat-insulating formwork 11 from the concrete foundation 50 can be reliably prevented.

In addition, since the base spacer 17, the top spacer 18 and the separator 19 are joined to the reinforcing material 13 of the basic heat-insulating formwork 11, they are joined to the base material 12 made of a foam-based heat insulating material even when an external force is applied. The joint is less likely to be damaged than in the case. Therefore, it is possible to more reliably prevent the heat-insulating formwork 11 from peeling off from the concrete foundation 50. In addition, the base spacer 17,
Since the top spacer 18 and the separator 19 are separate from the basic heat-insulating formwork 11, the basic heat-insulating formwork 11 can be made compact compared to the case where they are integrated, and can be stacked well during transportation. Can be. Therefore, it is possible to improve the efficiency of transportation of the basic heat insulating formwork 11.

Thus, the basic heat-insulating forms 11 can be connected to each other. Thus, the separator 19
Since the basic heat insulating molds 11 and 11 are connected to each other at three points of the intermediate member 35 and the pair of bolt members 36 and 36, the intermediate portions of the basic heat insulating molds 11 and 11 can be connected to each other with a small number of parts and a small effort. Can be linked.

When connecting the intermediate portions of the basic heat-insulating molds 11, 11, the male screw portion 42 of the one bolt member 36 of the separator 19 is inserted into the separator mounting hole 15 of the one basic heat-insulating mold 11 from outside. And the male thread portion 42 of the other bolt member 36 of the separator 19 is inserted into the separator mounting hole 15 of the other basic heat insulating form 11 from the outside. For example, the intermediate member 35 of the separator 19 is inserted from above, and the male threads 42 of the bolt members 36 are passed through the half-split portions of the nut portions 38 so that the male thread portions 42 of the bolt members 36 are radially inserted into the nut portions 38. Fit from the outside,
One of the basic heat insulating formwork 11 is held between the head 43 of one bolt member 36 and one nut portion 38 of the intermediate member 35, and the other bolt member 36 and the other nut portion 38 of the intermediate member 35 hold the other one. Can be connected to each other by sandwiching the basic heat-insulating formwork 11.
As described above, since the separator 19 can be joined by fitting the intermediate member 35 and the bolt members 36 and 36 in the radial direction without screwing, the basic heat insulating form 1
It is possible to improve the workability of the connection work between the 1, 1 and 11. Specifically, it is possible to finish the reinforcement arrangement on the base base B and to attach the separator 19 with one touch after the base heat insulating molds 11, 11 are arranged.

Since the support portion 31 capable of supporting the single tube 30 is formed outside the single tube 30, the single tube 30 can be directly supported by the top spacer 18 that connects the basic heat insulating molds 11, 11, and the support portion is separately provided. There is no need to provide them, and mounting work can be reduced. In addition, since the anchor bolt 32 is attached to the top spacer 18 in a state where it is positioned, it is not necessary to separately position and embed the anchor bolt in the foundation. Here, if the base spacer 17 and the top spacer 18 are integrally molded products made of a synthetic resin, the manufacture becomes easy.

In place of the base spacer 17,
The pier may be merely applied between the two base heat-insulating forms 11. Further, instead of the separator 19, a separator 52 including a shaft member 51 and a head member 52 shown in FIG. 12 may be used. The shaft member 51 has a head 53 having a diameter larger than that of the separator mounting hole 15 at one end, and an engaging projection (engaging portion) 54 having a diameter smaller than that of the separator mounting hole 15 at the other end. A substantially cylindrical shaft portion 55 having a smaller diameter than the separator mounting hole portion 15 is formed between them. The head member 52 has, at one end, a head portion 56 having a larger diameter than the separator mounting hole portion 15, and a shaft portion 5 having a smaller diameter than the separator mounting hole portion 15 at the other end.
7 is formed, and an engagement concave portion 58 that engages with the engagement convex portion 54 is formed inside the shaft portion 57. Then, by inserting the engaging projections 54 into the engaging recesses 58 and rotating them relative to each other by a predetermined angle, they do not engage and disengage.

That is, the separator 52 is formed with the separator mounting holes 15,
The shaft portion 55 inserted into the shaft portion 55 is formed on the side opposite to the head portion 53 that comes into contact with one of the basic heat-insulating forms 11 when the shaft portion 55 is inserted into the separator hole 15 and the head portion 53 of the shaft portion 55. The shaft member 51 having the engaging protrusion 54 and the shaft 55 of the shaft member 51 are inserted into the separator mounting holes 15 formed in the heat insulating base frames 11. And a head member 52 that comes into contact with the other basic heat-insulating formwork 11 by engaging with the base heat-insulating formwork 11.

When this separator 52 is used, when connecting the intermediate portions of the basic heat-insulating molds 11, 11, the shaft mounting members 15, 15 formed in the two basic heat-insulating molds 11, 11 are fitted with shaft members. When the head member 52 is engaged with the engaging projection 54 with the shaft portion 55 of the shaft 51 inserted, the shaft member 5
The head 53 and the head member 52 of the first base are both heat-insulated formwork 11, 1
1. Determine the position in the spreading direction. As described above, since the separator 52 can be joined only by engaging the shaft member 51 and the head member 52, the base heat insulating form 11,
It is possible to improve the workability of the connection work between the 11 units. Therefore, attachment of the basic heat-insulating formwork 11 can be simplified.

The shaft portion 55 of the shaft member 51 may have a cross-shaped cross section as shown in FIG. In addition, it is also possible to provide a plurality of separators 19 above and below the pair of reinforcing members 13, 13, especially when the base heat insulating molds 11 are adjacent to each other in the longitudinal direction of the base. It is preferable to provide a plurality of connection portions.

As described in detail above, claim 1 of the present invention
According to the described basic heat insulating formwork, it is connected to another basic heat insulating formwork adjacent in the longitudinal direction of the base via the reinforcing material, so that the strength of the connecting portion can be secured. Therefore, it is possible to prevent the connection portion with another heat insulating base form from being damaged at the time of placing concrete.

According to the basic heat insulating form of the second aspect of the present invention, the inside of the groove formed by the cutout formed at the end in the longitudinal direction of the base and the cutout of the other basic heat insulating formwork. To
Since the reinforcing material is disposed, the amount of protrusion of the reinforcing material from the base material in the thickness direction of the foundation can be suppressed. Therefore, since it does not get caught on the reinforcing material and does not cause peeling, it is possible to maintain a good state even after the foundation is constructed.

According to the basic heat insulating form of the third aspect of the present invention, a groove is formed at a position between the notches of the base material,
Since the reinforcing material is arranged in the groove, not only the connection portion with the other basic heat-insulating formwork but also the intermediate portion is reinforced. Therefore, it is possible to prevent the intermediate portion from being damaged at the time of placing concrete.
