  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  First, in FIGS. 1 to 5, a heat insulating foundation DK according to the present invention suitable for a building for cold districts has a chestnut stone group 1 laid on the ground E and a relatively thin wall laid on the upper side of the chestnut stone group 1. Abandoned concrete S and foundation concrete C laid and laminated on the upper side of the abandoned concrete S are provided.

  The base concrete C has a base part Cb that is formed thicker than the discarded concrete S and covers the upper surface of the discarded concrete S, and a band that stands vertically from a part of the base part Cb and extends vertically and horizontally from the base part Cb. A plate-like rising portion Ca is integrally formed, and heat-insulating molds K1 and K2 formed in a plate shape from a heat insulating material such as foamed polystyrene are joined to both sides of each rising portion Ca. Each of the heat insulating molds K1 and K2 is formed in a predetermined rectangular size, and is used in a tandem arrangement so as to form a strip on the base portion Cb.

  In addition, in each center part of the base part Cb and the rising part Ca in the basic concrete C, a reinforced steel frame (not shown) is appropriately arranged as in the case of conventional ordinary reinforced concrete, and the reinforcing bar is connected to the concrete part. In cooperation, the foundation concrete C is given sufficient strength. On the rising portion Ca of the foundation concrete C, the building wall W or the partition wall W ′ of the building is fixed and supported directly or via joists.

  In the illustrated example, the base portion Cb of the foundation concrete C is formed such that the outer peripheral portion 2 is thicker than the inner portion, and the discarded concrete S, the chestnut group 1 and the ground correspond to the thickness change of the base portion Cb. Each E is also formed at a medium to high height, whereby the foundation concrete C is more stably supported on the ground E.

  The rising portion Cb is arranged on the inner side of the base portion Ca so as to follow the outer peripheral rising portion CaO rising from the outer peripheral portion 2 of the base portion Ca and the inner side of the outer peripheral rising portion CaO so as to be along the outer periphery of the building. And an inner rising portion CaI. Among them, the outer peripheral rising portion CaO is joined to the inner side surface thereof with the first heat insulating mold K1 formed at the rising height from the upper surface of the base portion Cb, and to the outer side surface thereof from the upper surface of the discarded concrete S. A second heat insulating mold K2 formed at a rising height (and thus taller than the first heat insulating mold K1) is joined. On the other hand, the pair of first heat insulating molds K1 and K1 formed at the rising height from the upper surface of the base portion Cb are joined to the left and right side surfaces of the inner rising portion CaI.

  Between each of the relatively short first heat insulation formwork K1 and the base portion Cb, the first heat insulation formwork K1 is placed on the discarded concrete S before the foundation concrete C is placed in the construction process of the heat insulation foundation DK. Heat-insulating frame supports M and M 'for supporting the height adjustable are interposed in an upright state. In this embodiment, the discarded concrete S is formed at a medium height, and the upper surface height of the discarded concrete S is different between the outer peripheral portion and the inner portion thereof. In this case, the support M that stands on the outer peripheral part is longer than the support M 'that stands on the inner part. However, if the discarded concrete S is not formed at a medium height, the support of the same height is used. Can be used.

  In addition, between the second heat insulating form K2 and the base part Cb, the lower end of the second heat insulating form K2 is discarded and positioned on the concrete S before the foundation concrete C is placed in the construction process of the heat insulating foundation DK. In addition, a holding plate 3 having a U-shaped cross section for supporting directly (that is, not via the support tools M and M ′) is interposed. The holding plate 3 is discarded before the foundation concrete C is placed and fixed to a predetermined position on the upper surface of the concrete S with bolts b3, and the lower end of the second heat insulating form K2 is fitted and held on the holding plate 3 The second heat insulation mold K2 is positioned and temporarily fixed.

A mold holding body H on which the lower part of the heat insulating mold K1 can be placed and connected, and a height adjusting mechanism A that connects and supports the mold holding body H to the support bundle T so as to be adjustable in height. In this embodiment, the support bundle T of the outer support M is formed longer than the support bundle T of the inner support M ′. However, in this specification and the drawings, for convenience, Both support bundles will be described using the same reference symbol “T”.

  The support bundle T includes a seat portion Tf that is placed on the upper surface of the discarded concrete S and is fixed by a bolt b1, and a screw shaft portion Tb in which a lower portion is screwed into the seat portion Tf and extends upward. The screwing position of the screw shaft portion Tb to the seat portion Tf can be locked by a lock nut Tn that can be screwed to the screw shaft portion Tb and engage with the seat portion Tf. Accordingly, if the screw shaft portion Tb is rotated relative to the seat portion Tf while the lock nut Tn is loosened to adjust the screwing position of the screw shaft portion Tb to the seat portion Tf and then the lock nut Tn is tightened, The height of the shaft portion Tb, and thus the height of the support for the heat insulating mold K1, can be adjusted within a limited range.

  In addition, the mold holding body H is provided on a horizontal plate portion Hh on which the lower end of the first heat insulating mold K1 can be placed, and is erected on one end of the horizontal plate portion Hh, on the lower side surface of the first heat insulating mold K1. A vertical plate portion Hv that can be contacted and fixed integrally is formed in a L-shaped cross section from a synthetic resin material, and the height adjusting mechanism A is formed on the lower outer surface of the vertical plate portion Hv. The housing 10 is integrally connected.

  In addition, a plurality of insertion holes 4 for bolts b2 for fixing the vertical plate portion Hv to the lower side surface of the first heat-insulating mold K1 are formed at intervals from each other. The lower part of the first heat-insulating mold K1 can be fixed to the vertical plate portion Hv by a bolt b2 screwed into the first heat-insulating mold K1. In the illustrated example, one mold holding body H is formed such that the lower ends of the adjacent end portions of two adjacent first heat insulating molds K1, K1 straddle between the two heat insulating molds K1, K1. The horizontal plate portion Hh is placed on the vertical plate portion Hv and fixed to the vertical plate portion Hv by bolts b2. However, the fixed portion of the heat insulating mold K1 can be arbitrarily selected.

  The height adjusting mechanism A includes the housing 10 connected to the vertical plate portion Hv, a screw shaft portion Tb that constitutes at least the upper portion of the support bundle T and penetrates the housing 10 up and down, and the screw shaft portion Tb. A nut member 11 that is screwed into the housing 10 and accommodated in the housing 10 so as to be rotatable only, and is exposed to the outer surface of the housing 10 so that it can be rotated from the outer side so that the housing 10 can only rotate. The supported member 12 to be supported, and interposed between the operated member 12 and the nut member 11 and accommodated in the housing 10, rotate the nut member 11 in conjunction with the rotation operation of the operated member 12. And a gear mechanism G to be operated. On the outer end surface of the operated member 12, an engagement hole 12a for tool engagement is formed. Instead of the engagement hole 12a, a rotary operation knob may be integrally provided at the outer end of the operated member 12.

  In the illustrated example, the gear mechanism G includes a worm 13 that is concentrically fitted to the operated member 12 and rotates integrally with the worm wheel 11, and a worm wheel 11 w that is screwed into the worm 13. 11w is comprised integrally with the nut member 11, ie, the outer peripheral part of the nut member 11 is provided with the screw part screwed together with the worm 13.

  In the illustrated example, the housing 10 is divided into a housing main body having a lower end opened and an opening / closing lid that is detachably attached to the lower end opening of the main body by a coupling means such as a screw.

  The pair of first heat insulation molds K1 and K1 joined between the first and second heat insulation molds K1 and K2 respectively joined to both sides of the outer peripheral rising part CaO and between the both sides of the inner rise part CaI. Between each other, a plurality of couplers J for holding the intervals between each other at a constant interval before the foundation concrete C is placed in the construction process of the heat insulating foundation DK are interposed.

  Referring also to FIGS. 8 to 10, each of the couplers J has a conventionally well-known structure as a concrete form coupling means (generally called a foam tie). That is, as shown in FIGS. 8 and 9, the coupler J includes a heat-insulating mold K1 and K2 that face each other; a length-adjustable separator 20 that can hold an arbitrary distance between K1 and K1, and the separator 20 between one end flange portion 20a of the first connecting member 21 with the flange 21a sandwiching one heat insulation mold frame K1 between the other end flange portion 20b of the separator 20 and the other heat insulating mold frame K1 ( K2), a second connecting member 22 with a flange 22b, a pair of upper and lower pipe-shaped horizontal ribs 23 that support the outside of the other heat-insulating formwork K1 (K2), and the horizontal flange 23 as the other thermal insulation. A receiving frame 24 detachably coupled to the second connecting member 22 is provided so as to be sandwiched and fixed with the mold frame K1 (K2).

  The first and second connecting members 21 and 22 are detachably coupled to both ends of the separator 20 via short screw rods 25 and 26, respectively. Therefore, after the foundation concrete C is formed, FIGS. 11 (G), both connecting members 21 and 22 can be removed from the separator 20, and along with this, the horizontal bar 23 can also be removed.

  Next, referring to FIGS. 11 and 12 together, an outline of an example of the construction process of the heat insulation foundation DK of the present embodiment will be described. That is, in the construction process, a large number of chestnut stone groups 1 are laid on the ground E, and a thin-walled discarded concrete S is laid on the ground E (FIG. 11A), and the upper surface of the discarded concrete S is mutually connected. One of the pair of heat insulating molds K1 and K2 arranged at intervals (first heat insulating mold K1) is fixed and supported via height-adjustable supports M and M ′, and either one of the other (2nd heat insulation formwork K2 or 1st heat insulation formwork K1) The process which discards and fixes and supports to the upper surface of concrete S directly or via support tools M and M '(Drawing 11 (B)-(D)) And a pair of heat-insulating molds K1, K2; K1, K1 facing gaps 30 and abandoned concrete S for concrete concrete NC is placed on the abandoned concrete S, and the base part of the foundation concrete C is disposed on the abandoned concrete S. Cb and rising part Ca Step of forming (FIGS. 11 (E) and (F)), and after the foundation concrete C is formed, the portion of the joint J protruding from the heat insulating molds K1 and K2 is removed, and the ground E on the outer peripheral portion of the heat insulating foundation DK At least a step of backfilling (FIG. 11G).

Next, the above construction process will be described more specifically.
[Installation work of rebar and insulation formwork on discarded concrete]
After laying the discarded concrete S on the ground E via the chestnut group 1, the ink is drawn on the flat upper surface of the discarded concrete S, and the holding plate is placed at a predetermined position corresponding to the outer peripheral rising portion CaO in the outer peripheral portion of the upper surface. 3 is fixed with the bolt b3 and the seat Tf of the support bundle T of the support M is fixed with the bolt b1 so that the support M is held in an upright position. By fixing the seat portion Tf of the supporting bundle T of the supporting tools M ′ and M ′ paired at a predetermined position corresponding to the part CaI with the bolt b1, the paired supporting tools M ′ and M ′ are held in the standing posture. (FIG. 11B).

  After that, at the outer peripheral portion of the upper surface of the discarded concrete S, the mold holder H of the support M in the standing posture is adjusted to a desired height with respect to the support bundle T, and the mold holder H is placed on the mold holder H. The lower part of the first heat insulation mold K1 is placed and fixed with bolts b2, and the lower part of the second heat insulation mold K2 is fitted and held on the holding plate 3, and the first and second heat insulation molds K1 are further fitted. , K2 are joined at a predetermined interval via a coupler J (FIG. 11C), and further, a pipe-like shape that supports the outside of one heat insulation mold (the second heat insulation mold K2 in the illustrated example). The horizontal bar 23 is fixed to the coupler J (FIG. 11D).

  On the other hand, in the inner part of the upper surface of the discarded concrete S, the formwork holders H, H of the paired supports M ′, M ′ are respectively adjusted to the desired height with respect to the support bundles T, T. The lower portions of the first heat insulating molds K1 and K1 forming a pair on the mold holders H and H are respectively placed and fixed with bolts b2, and the pair of first heat insulating molds K1 and K1 are further paired. They are joined at a predetermined interval through the joint J (FIG. 11 (C)), and a pipe-shaped reed 23 supporting the outside of one heat insulating form K1 is fixed to the joint J (FIG. 11). (D)). The inner end portion of the facing gap 30 between the paired first heat insulating molds K1 and K1 is closed with another mold K3 (see FIG. 1) fixed on the discarded concrete S, and this mold K3. May be removed after completion of placing the concrete, or may be left as a third heat insulating form (in this case, formed with a heat insulating material).

  In addition, as a construction procedure different from the above (B) to (D), for example, one heat insulating form K2 (K1) of a pair of heat insulating forms K1, K2; 3 or after positioning and fixing on the discarded concrete S via the support M ′, the other heat insulation form K1 is joined and supported to the one heat insulation form K2 (K1) via the joint J, Thereafter, the support M or M ′ is discarded and installed and fixed at a predetermined position on the concrete S (a position directly below the other heat insulation mold), and the support M or M ′ is used to fix the other heat insulation mold. The lower part may be supported. As another construction procedure, for example, after the step (B), a heat insulating mold assembly in which a pair of heat insulating molds K1, K2; You may make it install on S via the holding | maintenance board 3 or the support tools M and M 'at once.

Thus, in parallel with the installation work of the first and second heat insulation molds K1, K2 on the discarded concrete S, or before or after the work, the base portion Cb of the basic concrete C and In the space corresponding to the rising portion Ca, a reinforcing work for installing and fixing a reinforcing bar for concrete reinforcement is performed. However, since the reinforcing work is conventionally known, the illustration of the reinforcing bar is omitted.
[Concrete work on abandoned concrete]
As described above, when the installation work of the reinforcing bars and the heat insulating molds K1 and K2 on the discarded concrete S is completed, the paired heat insulating molds K1 and K2; The ready-mixed concrete NC will be temporarily introduced. The input operation is first performed until the input concrete reaches a predetermined level on the discarded concrete S, whereby a portion to be the base portion Cb of the foundation concrete C is formed (FIG. 11E). In this case, when the input level of the ready-mixed concrete NC rises to a height that substantially matches the planned height of the base portion Cb (that is, the lower end height of the first heat-insulating formwork K1), the concrete input is temporarily suspended to become the base portion Cb. Level the top of the part flat.

  After the primary charging of the concrete, a predetermined time (for example, 30 minutes, however, it may vary depending on weather conditions such as temperature, humidity, etc.) has passed, and the previous concrete has hardened to some extent (that is, before it is completely cured). As shown in FIG. 11 (F), secondary charging of the ready-mixed concrete NC into the facing gap 30 is started. The charging operation is performed until the input concrete fills the opposing gap 30 and reaches the upper ends of the heat insulating molds K1 and K2, thereby forming the portions that become the rising portions CaO and CaI. In this case, after the primary charging of the concrete, since the input concrete has already hardened to some extent and the viscosity has increased after the predetermined time has elapsed, the level of the cast concrete that becomes the base portion Cb is secondarily charged. It is not pushed up by the weight of the concrete.

Thus, once the ready-mixed concrete NC is completely cured, the placement and molding of the foundation concrete C on the discarded concrete S is completed. In that case, since the secondary charging of the ready-mixed concrete NC is started before the predetermined time elapses after the primary charging is finished (that is, before complete hardening), the concrete portion corresponding to the base portion Cb that has been primarily charged. And the concrete portion corresponding to the rising portion Ca that has been secondarily charged are hardened in a state in which they are well-familiared with each other. Therefore, in the basic concrete C after forming, the base portion Cb and the rising portion Ca are struck between each other. A joint (seam) is not formed, and the risk of water leakage can be effectively reduced without a special water stop plate at the boundary.
[Partial removal of bonding tool and backfilling work]
After the foundation concrete C is formed as described above, as shown in FIGS. 2 to 4G, portions protruding from the heat insulating molds K1 and K2 of the coupler J (that is, the first and second connecting members 21). 22) and the horizontal bar 23 are removed from the separator 20 and removed from the heat insulating foundation DK, and the surrounding ground of the heat insulating foundation DK is backfilled.

  The heat insulating molds K1, K2 are left as they are in an integrally joined state on both sides of the rising portion Ca (CaO, CaI) of the basic concrete C as they are. Not only is the labor required to be removed specially improved, the workability is good, but also the heat insulation foundation DK can exhibit excellent heat insulation performance.

  As described above, the base part Cb and the rising part Ca (that is, CaO, CaI) of the foundation concrete C can be cast and formed all at once in a relatively short period of time on the discarded concrete S, thus simplifying the work process. And labor saving can be achieved, and the construction period and cost can be reduced.

  Further, as shown in the present embodiment, the heat insulating formwork supports M and M ′ used on the discarded concrete S before placing the basic concrete C can be placed and fixed on the upper surface of the discarded concrete S. In addition, the support bundle T standing vertically from the top of the discarded concrete S, the formwork holder H on which the lower part of the heat insulation formwork K1 can be placed and connected, and the formwork support body H to the support bundle T Since the height adjustment mechanism A that can be connected and supported in an adjustable manner is provided, the heat insulating formwork K1 can be accurately supported on the discarded concrete S by using the simple structural support tools M and M ′, and the support thereof. The height adjustment work of the heat insulating mold K1 supported by the tools M and M ′ can be easily performed.

  Further, the formwork holder H is placed on and fixed to a horizontal plate part Hh on which the lower end of the heat insulation formwork K1 can be placed, and is erected on one end of the horizontal plate part Hh so as to contact the lower side surface of the heat insulation formwork K1. Since the vertical plate portion Hv that can be used is provided, the heat insulating form K1 can be stably and accurately supported on the support bundle T with a simple structure.

  Further, as shown in the present embodiment, by rotating the operated member 12 with the tool engagement hole 12a exposed on the outer surface of the housing 10 provided continuously to the formwork holder H from the outer side, The height adjustment work of the heat insulating mold K1 can be easily performed from the side, and therefore, the heat insulating mold K1 and other obstacles are not obstructed (that is, the heat insulating mold K1 is placed on the mold holding body H). The height adjustment work of the heat insulation mold K1 can be performed efficiently and accurately (even in a supported state).

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various design changes can be made without departing from the present invention described in the claims. Is possible.

  For example, in the said Example, although the thing of the structure called what is called a solid foundation where the base part Cb of foundation concrete C covers the ground whole surface used as the ground was shown, the base part of this invention is only a part of the ground used as the ground. May be covered.

In the above embodiment, although the those in the second lower end of the heat-insulating mold K2 directly through the holding plate 3 to the base portion Cb (i.e. not via the supporting beam T) so as to support, retain plate 3 may be omitted, and the lower end of the second heat-insulating mold K2 may be fixed in a state of being in direct contact with the base portion Cb.

In the above embodiment, strike the pouring of concrete foundation C, and showed that as only to inject the raw concrete through opposing gap 30 of the heat-insulating mold K1, K2, not only the opposing gap 30 of its another Alternatively, the ready-mixed concrete may be poured onto the concrete S.
