[0019] As shown in FIGS. 2 and 3, the form / heat insulating panel P includes a panel body 1 and a fastening bar 20 that is detachably and integrally attached to the upper end surface of the panel body 1.

[0020] As shown in Figs. 2 to 4, the panel body 1 constitutes the main part of the heat-insulating panel P which is also used as a formwork, and is formed of a rectangular plate that is long horizontally, and has high heat insulation properties. It is made of a hard foamed synthetic resin material such as polystyrene or polyurethane, which has a light weight. And this panel main body 1 is measured and processed to the said dimension, and both the inner surface li (surface on the side which a placement concrete contacts) and the outer surface lo are formed in a flat surface.

[0021] As shown in Figs. 2, 4, 5, and 9, a plurality of assembly ties 40 (described later) are provided in the lower portion of the panel body 1 near the inner surface li at intervals in the longitudinal direction. A dead-end insertion hole 2 is provided in which one of the fastening ends 41 is inserted and connected. As shown in FIGS. 5 and 9, each insertion hole 2 has an opening 3 on the lower surface and an insertion port 5 covered with a thin wall 4 that is easily broken on the inner surface. As will be described later, it can be easily broken by inserting the assembly tie 40 (see FIG. 15).

[0022] As shown in Figs. 2 and 4, on the inner surface li (surface on the side where the concrete contacts) of the panel body 1, the insertion hole 2 indicating the position of the insertion hole 2 ··· A plurality of first streaks 6 made of narrow grooves extending vertically upward through the center of the panel 6 are arranged side by side in the longitudinal direction of the panel body 1, and further on the inner surface of the panel body 1. Has a plurality of narrow grooves (narrower than the streaks) in parallel with the first streaks 6. As will be described later, the streak 8 is used for positioning when stacking and building a plurality of heat insulating panels P for both formwork.

[0023] The center lines 8c of the plurality of second streaks 8 are at positions obtained by equally dividing the center lines 6c, 6c of the two adjacent first streaks 6, 6 respectively. Yes, center line 6c and second line of adjacent first streak 6 The distance between the center lines 8c of the streak 8 and the distance between the center lines 8c, 8c of the two adjacent second streak 8, 8 are all the same.

On the other hand, as shown in FIG. 3, the first streak 6 ··· and the first streak 6 ··· on the inner surface side of the panel body 1 are also formed on the outer surface lo (the surface opposite to the side on which the concrete contacts) on the panel body 1. Another first streak… and another second streak…… corresponding to the second streak 8… are arranged side by side, but the lower part of the first streak… Wall 4 does not exist. The first streak 6 ······ and the second streak 8 ···, 8 ^… are slightly wider than the first streak 6 ······· Is formed.

As shown in FIGS. 5 to 8, an upper surface vertical slit 10 is provided on the upper surface of the panel main body 1 so as to be biased toward the outer surface lo of the panel main body 1 over its entire length. A plurality of strips 11 (see FIG. 8) are provided at intervals in the longitudinal direction. A lower insertion portion 23 of a binding bar 20 (described later) is removably inserted into the vertical slit of the upper surface, and the plurality of protrusions 11 are closely related to the lower insertion portion 23 of the binding bar 20. In combination, the binding bar 20 is prevented from coming out. Further, a locking projection 12 is formed on the inner edge of the upper surface of the panel body 1, and this locking projection 12 is connected to the binding bar 20 when the binding bar 20 is inserted into the top vertical slit 10. Position 20.

As shown in FIGS. 5, 9, and 10, a lower surface vertical slit 15 corresponding to the upper surface vertical slit 10 is also provided on the lower surface of the panel body 1, and the lower surface vertical slit 15 is also provided in the longitudinal direction thereof. A plurality of retaining ridges 16 (see Fig. 10) are provided at intervals. An upper insertion portion 22 of a binding bar 20 to be described later is removably inserted into the lower surface vertical slit 15, and a plurality of protrusions 16 ··· are connected to the upper insertion portion 22 of the binding bar 20. Are closely engaged with each other to prevent the binding bar 20 from coming off.

Further, as shown in FIG. 2, the left and right end faces of the panel body 1 are provided with end face vertical slits 18 and 18 that are biased toward the outside thereof and extend over the entire length thereof. A plurality of strips 19 (see FIGS. 11 and 12) are provided at intervals in the longitudinal direction. The left and right insertion portions 32 and 33 of the connection bar 30 for connecting the panel bodies 1 and 1 together are inserted into the end surface vertical slits 18 and 18 in a freely detachable manner.

[0028] As shown in FIGS. 2, 3, 6, and 7, the panel body 1 is detachably attached to the upper surface of the panel body 1. The binding bar 20 is formed of a hard synthetic resin material with a T-shaped cross section, and has a substantially horizontal connecting portion 21 and a lower insertion portion 22 extending vertically from one side of the connecting portion 21 in a vertical direction. , 23. The connecting portion 21 is provided with a plurality of tightening holes 24, and the distance between the centers of these tightening holes 24 is a center line 6c between the first and second streaks 6, 8. It is equal to the interval of 8c.

[0029] As shown most clearly in FIGS. 6 and 7, the upper and lower insertion portions 22, 23 of the binding bar 20 are formed to be slightly tapered toward the tip, and are formed on the inner surfaces of the tips. Are formed with serrated retaining protrusions 22e and 23e, respectively.

[0030] The connecting portion 21 of the binding bar 20 is seated on the upper surface of the panel body 1, and the lower insertion portions 22, 23 are provided on the upper and lower vertical slits 15, 15 below the panel body 1, 1 to be stacked vertically. Plugged into 10 respectively. At this time, the upper and lower insertion portions 21 and 22 of the binding bar 20 are closely related to the plurality of protrusions 11 formed on the upper and lower vertical slits 10 and 15 of the panel body 1. This prevents the binding bar 20 from coming out of the panel body 1 and does not depend on a fixing means such as an adhesive.

As shown in FIGS. 2 and 3, the length of the binding bar 20 is shorter than the length of the panel body 1, and when the binding bar 20 is connected to the panel body 1, the panel body 1 Connection ends lj and lj where no binding bar 20 is present are formed at both left and right ends of the. The connection end portions lj and lj are connected to the left and right insertion portions 32 and 33 of the connection bar 30 in the end surface vertical slits 18 and 18 formed there, so that they can be freely inserted and removed. The ends of the adjacent panel bodies 1..., Which are stacked in a row on the top and bottom, are connected together via a connection bar 30.

[0032] As shown in Figs. 11 and 12, the connection bar 30 is formed in a T-shaped cross section by a hard synthetic grease material, like the binding bar 20, and has a substantially vertical connection part 31 and its connection part. It is composed of left and right insertion parts 32, 33 extending from one side of the 31 at right angles in the left-right direction. The insertion portions 32 and 33 are provided with protrusions 32e and 33e for preventing the protrusions, respectively. Thus, the connecting bar 30 is formed of the same material as the binding bar 20 in the same shape, but is different from the binding bar 20 in that it does not have the fastening hole 24.

[0033] As shown in FIGS. 1 and 2, the inner formwork Mi and the outer formwork Mo are built. Of the inner and outer formwork combined with heat insulation panel P, those facing each other at the same level are fastened together by an assembly tie 40. The assembly tie 40 is formed in a squirrel-like shape, and has left and right tightening ends 41 and 41 that are bent at substantially right angles at both ends, and these tightening ends 41 and 41 are connected to a plurality of binding bars 20. It is selectively inserted and connected to the holes 24.

[0034] Next, a method of constructing the wall formwork M using the formwork-cum-use heat-insulating panel P, which is useful in the present invention, will be described mainly with reference to FIG. 1 and FIGS.

[0035] In constructing the outer formwork Mo and the inner formwork Mi to be built in the concrete placement space S with the reinforcing bars F, one side thereof, in this embodiment, first, the outer form The frame Mo is built prior to the inner mold Mi. In other words, the heat-insulating panel P for both the formwork and the outer formwork Mo is stacked from the bottom to the top through a plurality of intermediate stages. In this stacking operation, the stacking position of the upper and lower mold / heat insulation panel P is marked by the second streaks 8 ···· 8 ', and in particular, the mold / heat insulation panel P is staggered. When stacking, by using the second streaks 8..., 8 ′ as a mark, the relative positions of the upper and lower formwork combined heat insulation panels P can be accurately positioned and accurately stacked.

[0036] The upper and lower mold / heat insulation panels P, P are connected to each other via the binding bar 20 as described above. When the outer formwork Mo is built by this stacking, the inner surface of the outer formwork Mo, that is, the surface in contact with the cast concrete, is placed on the lower part of each formwork and heat insulation panel P as shown in FIGS. The easy-to-break thin walls 4 that cover the insertion port 5 of the insertion hole 2 are exposed to the outside, and the position of these thin walls 4 is instructed so that the external force can be easily understood by the first streaks 6. Is done. Then, as shown in FIG. 15, the fastening end 41 of the assembly tie 40 is pushed through the thin wall 4 to be inserted into the insertion hole 2 and is pushed downward, whereby one of the assembly tie 40 is fastened. As shown in Fig. 1, the end 41 is inserted into the fastening hole 24 of the binding bar 20 and connected to the inner surface of the outer mold Mo (the surface on the concrete placement side). Combined heat insulation panel Ρ ················ One of the fastening ends 41 of the plurality of assembly ties 40 can be connected.

[0037] As shown in Fig. 13, after a plurality of assembly tie 40 are connected together in a plurality of formwork and heat insulation panels の of the outer formwork Mo, a formwork and heat insulation panel for constructing the inner formwork Mo is formed. The other fastening part 41 of the assembly tie 40 is connected to the fastening hole 24 of the The inner wall of the mold Mo and the heat insulation panel P for the inner mold P are one-stage while pushing through the thin wall 4 and connecting the other fastening part 41 of the assembly 40 through the insertion hole 2 to the fastening hole 24). Build in order from the bottom to the top.

[0038] As shown in Fig. 1, the outer surface of the outer mold frame Mo and the inner mold frame Mi are provided with first streaks on the outer surfaces (surfaces opposite to the concrete placement space S). Thus, the positions of the plurality of assembly ties 40 connecting them can be confirmed from the outside of the molds Mo and Mi.

[0039] By the way, as described above, in the past, when the inner and outer heat insulating panels for both the formwork and the outer frame were built, each time the heat insulating panels were stacked, the two panels were connected with an assembly tie to the heat insulating panel. Since the panels are built, two workers on both sides of the inner and outer insulation panels perform the construction work, or one worker moves alternately on both sides of the inner and outer insulation panels. Inefficiency that must be erected in this example In this example, as described above, one side, that is, one of the outer and inner molds Mo and Mi is erected in advance and the erection is performed. A single formwork (outer formwork Mo or inner formwork Mi) is also used as a formwork and heat insulation panel Ρ ······ A number of assembly ties 40 · "are joined together, and then the other formwork (inside Formwork of formwork Mi or outside formwork Mo) Since the heat insulation panel 用 ··· can be built with the assembly tie 40…, it is possible to install those formwork Mo and Mi without one worker moving in and out of the formwork. This can be done and the work efficiency can be significantly increased.

[0040] As described above, when the outer and inner molds Mo and Mi are completely built, concrete is placed in the concrete placing space S therebetween. At this time, even though the thin wall 4 of the insertion hole 2 of the heat-insulating panel P for formwork is pushed and broken by the fastening end 41 of the assembly 40, most of the insertion port 5 is a thin wall 4 Since the gap of the insertion port 5 is very small, it is possible to suppress the penetration of the slot into the insertion hole 2 into which the assembly tie 40 is inserted as much as possible. Further, since no slot is inserted into the insertion hole 2 when the assembly tie 40 is not inserted, the penetration of the slot does not cause a decrease in the thermal insulation performance of the heat insulating panel P for formwork.

[0041] As described above, the concrete is placed in the concrete placement space S between the outer and inner molds Mo and Mi. The concrete frame is constructed by placing the cleats, but after the concrete frame is constructed, the outer and inner molds Mo and Mi are used as they are as heat insulation walls of the building without being removed.

[0042] According to this embodiment, the inner surfaces of the outer and inner molds Mo and Mi are flat, and only the rod-shaped portion of the assembly tie 40, which is a binding member, is provided in the concrete placing space S. By not existing, the volume of the binding member is reduced to suppress the cross-sectional defect of the concrete frame, and thus a high-strength concrete frame that is excellent in concrete placement and free from the occurrence of jyanka can be constructed.

[0043] Further, according to this embodiment, the inner and outer mold forms Mi and Mo can be built in the conventional manner.

[0044] Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and various embodiments are possible within the scope of the present invention.

[0045] For example, in the above-described embodiment, the force described in the case where the outer formwork Mo is built prior to the inner formwork Mi is constructed such that the inner formwork Mi is built prior to the outer formwork Mo. May be.
