Description

  In the present invention, the exterior material and the heat insulating material constituting the formwork panel can be connected to the exterior material and the heat insulation material of the adjacent formwork panels, respectively, so that the connection strength is high and a finish after placing the concrete is required. The present invention relates to a formwork panel and a construction structure of a concrete wall body that can be used as they are as an exterior material, and can also prevent leakage of noro from a connection portion between adjacent panels.

  Conventionally, when constructing concrete structures, dual-purpose formwork using exterior materials and base materials (heat insulation materials) as the formwork has been proposed, and most of them use heat insulation material as a formwork, and after the concrete is cured, Finishing treatment (applying decorative material, laying exterior material) is performed.

Patent Document 1 discloses a method of placing concrete using a combined heat insulating material panel A having a structure in which a composite reinforcing material 7 is integrated with a heat insulating material 6.
However, in Patent Document 1, foam ties (registered trademark) 3 and separators 5, which are metal fittings for mold fastening, penetrate through the heat insulating material 6 and the reinforcing material 7 and protrude to the surface (outside) of the reinforcing material 7. Therefore, there has been a problem that noro (cement water) leaks from the through hole. Moreover, since this noro is a strong alkali and soils the outer surface of the reinforcing material 7, it is necessary to wipe off the noro after curing or to cover the outer surface of the reinforcing material 7 with a finishing material (interior board 11). In addition, since the dual-purpose formwork is held down by the reinforcing material 7, it is necessary to perform the work from the outside of the dual-purpose heat insulating panel A, and a space for assembling a scaffold is required, and there is not enough space between the adjacent house and the like. ) Was difficult to build. In addition, the decorative finish after curing has a problem that the work becomes difficult in the case of a narrow area.

Patent Document 2 discloses a heat insulating wall outside a building in which a cement-based hard material 4 in which a tile 3 as a finishing material is integrated with a heat insulating material 2 is joined.
However, in this patent document 2, since the bolt of a anchor member 5, a nut, the edge part of a separator, etc. appear on the surface of the finishing material 3 as shown in figure, it was not preferable in design. In order to solve it, the same processing as in Patent Document 1 was necessary.

Japanese Patent Publication No. 7-6244 JP 11-315601 A

As described above, the formwork panels described in Patent Documents 1 and 2 require troublesome processing and finishing work after placing concrete, and can be used as they are as exterior materials or interior materials. It was something that could not be done.
In addition, since the connection structure between adjacent panels is not sufficiently described, it is unclear whether it can be applied to a large-area concrete structure. As described above, it was easily assumed that it was necessary to wipe off the paste after curing or to cover the outer surface of the surface layer material with a finishing material.

  Therefore, the present invention is capable of connecting the exterior material and the heat insulating material constituting the form panel to the external material and the heat insulating material of the adjacent form panel panels, respectively, so that the connection strength is high and the finish after the concrete placement is finished. The purpose is to propose a formwork panel that can be used as an exterior material as it is without being necessary, and can also prevent leakage of noro from the connection between adjacent panels, and a construction structure of a concrete wall And

The present invention has been proposed in view of the above, and is a formwork panel including an exterior material and a heat insulating material attached to the inside of the exterior material, and the exterior material includes a face plate portion serving as a finished surface, A connecting portion formed at both ends of the face plate portion, and a fixing portion formed by attaching a fixing member having a screw opening to the back surface side of the face plate portion. The heat insulating material has a stepped overlapping portion at one end and a portion to be polymerized that overlaps with the overlapping portion at the other end, and adjacent exterior members are engaged, fitted, or overlapped. The adjacent heat insulating materials can be connected to each other by overlapping the superposed portion and the polymerized portion, and the rod-like member disposed in the concrete placing space is connected to the fixing portion from the back surface side of the heat insulating material. The present invention relates to a formwork panel characterized by being able to be screwed and connected to a screw portion of Than is.

  The present invention also proposes a formwork panel characterized in that in the formwork panel, a cushioning material for preventing contact between the fixing material and the exterior material is interposed in the space portion.

  Further, according to the present invention, in the mold panel, the heat insulating material has through holes penetrating the front and back surfaces at predetermined intervals, and a rod-like member can be inserted into the through hole. A frame panel is also proposed.

  Furthermore, the present invention also proposes a construction structure for a concrete wall body, wherein the formwork panel is used as at least one formwork of a concrete placement space.

Since the formwork panel of the present invention can connect adjacent exterior materials by engagement or fitting or polymerization, and can connect adjacent heat insulating materials by polymerization, the connection strength between adjacent formwork panels is high. It becomes.
Moreover, even if it seems that leaks leak from the connection part of adjacent formwork panels, since the connection part of a heat insulating material is superposed | polymerized in step shape, a leaking out flow path becomes refractive. Moreover, because the exterior material is pulled inward by the rod-shaped member and the insulation is pushed outward from the inside by the concrete placing pressure, the density of the polymerized portion increases due to the pressure from both sides, so the refraction that turns around It can be eliminated as much as possible by pressing the gap. Further, since the fixing portion to which the rod-shaped member is connected from the concrete placement space is formed on the back surface side of the face plate portion of the exterior material, leakage to the surface of the face plate portion is prevented at this fixing portion.
And connection between adjacent formwork panels and the connection with the rod-shaped member arrange | positioned in concrete placement space can be performed very easily.
In this way, the formwork panel of the present invention can connect adjacent formwork panels with high connection strength, and even if noro leaks through the connecting parts and rod-shaped members between the formwork panels, Since these can be surely prevented, it is not necessary to separately finish (wipe off) the exterior material and can be used as it is. Further, it may be transported with a nut or the like attached as a fixing material, and can be handled as a flat boat, can be stacked, and leads to a reduction in transport cost.
In addition, a space portion that opens laterally is provided on the back surface side of the face plate portion, and a fixing member having a screw portion is attached in the space portion to form a fixing portion, so that the rod-shaped member is transmitted from the concrete placement space. Thus, even if the slot enters the fixing portion, leakage to the surface of the face plate portion is prevented in this space portion.

  In addition, when a cushioning material that prevents contact between the fixing material and the exterior material is interposed, for example, if the fixing material is a nut, the nut head does not directly contact the back surface of the exterior material. There are no traces in the area.

  In addition, when the through-holes penetrating the front and back surfaces are opened at predetermined intervals in the heat insulating material, and the rod-shaped member can be inserted into the through-holes, the formwork panel with the rod-shaped member protruding into the through-hole After laying at a predetermined position, the rod-shaped member may be tightened, and the connecting operation can be performed very simply. As described above, a part of the spacing member (separator) can be used as the rod-shaped member, and a mold can be easily constructed.

Furthermore, the concrete wall construction structure of the present invention uses the above-mentioned formwork panel as a formwork for the concrete formwork method, and variously select a heat insulating material and an exterior material as described above. The concrete wall of the specification can be easily and inexpensively constructed.
For example, by using a high-strength metal face material as the exterior material, it can be applied to a wall having a large area with strength against the concrete placing pressure. Further, when the exterior material is used as a finishing material, since the fixing portion is provided on the back side of the exterior material, the construction from the outside is not necessarily required, and the construction only from the inside is possible. In this case, an outer scaffold is unnecessary, and cost can be reduced. Furthermore, since no scaffold is required on the outside, construction can also be performed on a site (construction site) where the scaffold cannot be assembled.

FIG. It is a perspective view which shows the state which tries to connect a formwork panel further to what connected the 2nd formwork panel of 1st Example. It is a perspective view which shows the state which connected the three formwork panels of 1st Example. (A) Cross-sectional view showing a state in which the formwork panels of the second embodiment are arranged in parallel, (b) Cross-sectional view showing a state in which two surfaces are connected in series, (c) An enlarged cross-sectional view showing the exterior material used is there.

The formwork panel of the present invention comprises an exterior material and a heat insulating material attached to the inside of the exterior material. Adjacent exterior materials can be connected to each other by engagement, fitting, or polymerization. It can be connected by polymerization and has high connection strength between adjacent form panels.
And the rod-shaped member arrange | positioned in concrete placement space can be screwed together and connected to the screw part of the fixing | fixed part formed in the back surface side of the exterior material from the back surface side of the heat insulating material.

The heat insulating material and the exterior material constituting the formwork panel are separately molded, and can be appropriately selected to have a desired configuration. For example, if the strength and other characteristics of the entire formwork panel are to be set to desired levels, the desired characteristics can be obtained by appropriately selecting these heat insulating materials and exterior materials.
Below, a heat insulating material and an exterior material are each demonstrated.

The heat insulating material is not particularly limited as long as it has a step-like overlapping portion at one end and a portion to be polymerized with the overlapping portion at the other end. .
For example, heat insulating materials of various materials can be applied. For example, the board is not limited to a synthetic resin boat, and may be a wooden board, or may be a single layer or multiple layers, or may be composed of multiple layers of different materials. Therefore, functional board materials such as flame retardancy and nonflammability may be used, and there is no limitation on the thickness and the like, and any heat insulating material may be used.
In addition, on the surface side of the heat insulating material, a concave portion for accommodating (or positioning) the fixing portion of the exterior material may be provided, or a concave space is formed in a connection portion between the overlapping portion and the portion to be polymerized. May be.
Moreover, since only one exterior material may be attached to the integral heat insulating material or two or more exterior materials may be attached, a plurality of the recesses and the recessed spaces may be provided.

  In this heat insulating material, it is desirable that through holes penetrating the front and back surfaces are opened at a predetermined interval, and a rod-like member disposed in the concrete placing space can be inserted into the through holes. In this case, the formwork panel can be laid in a state in which the rod-shaped member is protruded in the through hole, and after the rod-shaped member is tightened after being laid at a predetermined position, the connecting operation can be carried out very simply. Moreover, you may provide suitably the reinforcement board for reinforcing the placement pressure of concrete on the surface or back surface side of this heat insulating material.

As the exterior material, it is formed on the back plate side of the face plate portion, the face plate portion to be the finished surface, the connection portions formed at both ends of the face plate portion, that is, at least a pair of opposing edges (for example, up and down, left and right). Other configurations are not particularly limited as long as the fixing unit has a screw part.
Since the face plate portion is a finished surface, the face plate portion may be substantially flat or may have an arbitrary design (decorative) property, and the shape is not particularly limited.
In addition, the connecting portions are connected by engagement, fitting, or superposition, and are rarely provided with the same shape at both ends. Therefore, one is hereinafter referred to as a connecting portion and the other is referred to as a connection receiving portion.
For example, the exterior material is not limited to a material or a molding method, and various material face materials can be applied. A metal face material or a hard resin plate may be used, or an extrusion mold material such as aluminum may be used. Good.

  When the exterior material is formed of a metal face material or a hard resin plate, both ends of the face plate portion to be a finished surface, that is, at least a pair of opposing edges (eg, top and bottom, left and right) are provided with connection portions, for example for polymerization. One of the connection parts is bent to the back side, and further bent to the inside, the other connection receiving part is bent to the back side, Furthermore, it is good also as a structure which has the superposition | polymerization piece bent outside.

In the case of forming the exterior material with an extrusion mold material such as aluminum, a connecting portion connectable to both ends of the face plate portion serving as a finished surface, that is, at least a pair of opposing edges (for example, top and bottom, left and right) is provided. When connecting by fitting or fitting, high strength and elasticity are imparted, so that the assembled state such as engagement or fitting is maintained elastically and stably, and the connection can be made easily.
Although the thickness is not particularly limited, the thickness is generally 1.2 to 1.6 mm or more, and the surface may be distorted or deformed even if some stress such as concrete pouring pressure is applied. Those with less strength are more desirable. However, because of the general problem (practical) of the width of about 200 mm, the exterior material made of this extrusion mold material has a plurality of the heat insulating materials that are usually molded to a width of nearly 1 m because of problems such as molding or cost. A sheet of exterior material is attached.
In addition, as this exterior material, a kind of exterior material may be used, 2 types (or more) of exterior materials may be used, and in the case of 2 types (or more), the width may be different. . The following description will be made assuming that one or two types of exterior materials are used. Even if two types of exterior materials are used, it is not necessary to provide a space in each exterior material, and it is sufficient to provide at least one of them. That is, when two types of exterior materials are used, there are many specifications in which one exterior material is provided with a space portion and the other exterior material is not provided with a space portion. Even when two types of exterior materials are used, the connecting portions provided in the respective exterior materials may be the same or different.
In addition, for this exterior material, one exterior material may be attached to the integral heat insulating material, but due to the above-mentioned problem of the molding width, a plurality of exterior materials are added to the integral heat insulating material. Therefore, a plurality of kinds of exterior materials are attached to the integral heat insulating material, or two kinds of exterior materials are attached to the integral heat insulating material one by one or plural sheets.

Next, the fixing unit provided on the back side of the face plate part will be described.
The fixing unit may be any unit provided with a screw part for screwing the rod-shaped member, and may be a female screw part or a male screw part.
When the fixing portion has a female screw portion and the rod-shaped member has a male screw portion;
As shown in the illustrated embodiment to be described later, the fixing portion is a plate-like material in which a square nut such as a hexagon nut or a square nut or a plurality of female screw portions is screwed, or a thick piece of polymerized piece. And may be tapped (female threaded). The rod-shaped member in that case uses a rod-shaped bolt material or the like. In addition, when shape | molding an exterior material with an extrusion die material as mentioned above, it can respond easily also to the aspect which shape | molds a thick to-be-polymerized piece.
When the fixing portion has a male screw portion and the rod-shaped member has a female screw portion;
The fixing portion may be one in which a bolt is erected on the outer side (= heat insulating material side) of the space portion (fixed by welding or the like), or one in which the bolt is erected from a hole. In this case, as the rod-shaped member, at least the tip thereof is subjected to female thread processing, or a cylindrical member is used.

Particularly preferably, a space portion that is open to the side or the back surface side may be provided on the back surface side of the face plate portion, and a fixing material having a screw portion may be attached in the space portion to form the fixing portion. As the fixing material in this case, examples of the fixing material provided with the female screw portion include the above-described hexagonal nut, square nut such as a square nut, and a plate-like material provided with a plurality of female screw portions, and a male screw portion. Examples of the fixing material include the aforementioned bolts. As described above, when the exterior material is formed by an extrusion mold material, the holding (clamping) strength of the fixing material is also high.
When a general-purpose nut is used as the fixing part, the head of the nut has a square shape, so that rotation (spinning) is prevented even when a rod-shaped member (bolt material) is attached.

It should be noted that it is desirable not to provide only the fixing material in the space, but to interpose a buffer material that prevents contact between the fixing material and the exterior material. For example, the fixing material is pressed against the exterior material so that no trace or the like is generated on the face plate portion of the exterior material.
This buffer material may be the same material as the heat insulating material, or may be an elastic material such as rubber. Further, the cushioning material may be provided continuously in the space portion, or may be provided only at the nut intervening portion (tip position of the rod-shaped member). Furthermore, it may be provided in advance or on the back surface side of the exterior material at the time of installation work, or may be provided on the upper part (nut head) of the fixing material.

Next, a rod-like member that is screwed and connected to the screw portion of the fixing portion from the back surface side of the heat insulating material will be described.
This rod-shaped member has a screw receiving portion that is screwed into the screw portion of the fixing portion. When the fixing portion has a female screw portion such as a nut, a male screw portion is used as the rod-shaped member. What is necessary is just to use the bolt material etc. with which it is equipped, and it may serve as a part of space | interval holding member (separator) like the Example shown later. Further, when the fixing portion has a male screw portion in which a bolt is erected, a cylindrical member having a female screw portion may be used as the rod-like member.
In the illustrated embodiment to be described later, a hook-shaped material (pressing member) is provided, but the presence or absence, shape, etc. of the hook-shaped material are not particularly limited. Further, even when a bowl-shaped material is used, it is not always necessary to use it for all the rod-shaped members, and it may be used at an arbitrary position such as a predetermined row or corner. That is, what is necessary is just to provide suitably according to the specification and intensity | strength of the integrated means of an exterior material and a heat insulating material, or the whole intensity | strength.

  The formwork panel of the present invention in which each of these members is disposed is manufactured by the following molding process, integration process, and connection process. In addition, when attaching a plurality of one type of exterior material to an integral heat insulating material, the connection structure is one type, but here two types of exterior materials each having a different connecting portion to the integral heat insulating material, An example of attaching a total of 4 sheets is shown.

Molding process First, for the exterior material, there are two types of exterior materials, an exterior material having a fixing portion (for convenience, the first exterior material) and a non-exterior material (for convenience, the second exterior material). Is used so that it is connected to the connecting portion of the adjacent edge at both ends of each exterior material. That is, the connection portion A on one side of the first exterior material can be connected to the connection portion D on the other side of the second exterior material, and the connection portion B on the other side of the first exterior material is one side of the second exterior material. It is possible to connect to the connection part C. When these connection parts A and D and connection parts B and C are connected by engagement or fitting, an elastic engagement part or elastic fitting is formed.
In addition, since the fixing portion is provided on the back surface side of the first exterior material, a fixing material such as a nut is accommodated in the fixing portion to form a fixing portion. Note that when there is a concern about displacement or separation of the fixing material, it may be appropriately bonded using an adhesive or the like.
On the other hand, for the heat insulating material, in the case of a single layer as shown in the illustrated embodiment described later, by providing a space portion of the exterior material on the surface side, and providing a recess for fitting an outer portion forming the space portion, Arrangement can be made without causing any deviation of the exterior material.

-Integration process Although the said 2 types of exterior materials are laid in parallel on the surface of the said heat insulating material, what is necessary is just to combine and connect suitably according to the aspect of each connection part of 2 types of exterior materials.
The heat insulating material and the exterior material are integrated to such an extent that they are not separated or misaligned when using the formwork panel, but the means is not limited. For example, the back surface of the face plate portion is bonded to the surface of the heat insulating material. It may be a nail or the like. Alternatively, in the illustrated embodiment which will be described later, since the rod-shaped member is attached to the rod-shaped member and plays a role of holding down (pinching) the heat insulating material, it may be temporarily fixed. In addition, in the case of bonding and integrating, there is no limitation on the adhesive to be used or the bonding surface (not only full bonding but also partial bonding).

-Connection process As for the connection structure of the connection parts A and D and the connection parts B and C, assuming that they are connected by engagement, fitting, or superposition, as described above, in particular, when the exterior material is made of an extrusion mold material. The assembly state is maintained elastically and stably, and forms an elastic engagement portion or an elastic fitting portion. And, on the integrated heat insulating material, two kinds of exterior materials are installed, two each, for a total of four, so on the integrated heat insulating material, the connection structure of one connection part A, D and two connections The connection structure of the parts B and C is formed.

The formwork panel of the present invention manufactured by these processes is configured by arranging a total of four types of exterior materials such as metal face materials on the surface of a heat insulating material, and connects adjacent formwork panels. In doing so, the connection part A on one side of the first exterior material on the heat insulating material may be connected to the connection part D on the other side of the second exterior material on the adjacent heat insulating material. This connection is exactly the same as the connection of the first exterior material and the second exterior material on the surface of the heat insulating material described above.
And since this formwork panel can each connect the exterior materials and heat insulating materials in adjacent formwork panels, it can perform connection with high connection intensity | strength.

Moreover, the construction structure of the concrete wall of the present invention uses the formwork panel having the above structure as a formwork for the concrete formwork method. As described above, various insulation materials and exterior materials are appropriately selected. The concrete wall of the specification can be easily and inexpensively constructed.
And even if it is going to leak from the back surface side of a formwork panel, since the connection part of a heat insulating material is superposed | polymerized stepwise, a leak flow path becomes refractive. Moreover, because the exterior material is pulled inward by the rod-shaped member and the insulation is pushed outward from the inside by the concrete placing pressure, the density of the polymerized portion increases due to the pressure from both sides, so the refraction that turns around It can be eliminated as much as possible by pressing the gap. Furthermore, since the fixing portion provided on the back surface side of the face plate portion can also be prevented from leaking out, it can be used as an exterior material as it is without requiring troublesome processing and finishing work after placing concrete.

In the first embodiment shown in FIGS. 1 and 2 of the mold panel 1 of the present invention, a total of four exterior materials 2I and 2II are attached (adhered) to the surface of the integral heat insulating material 3, respectively, and integrated. The concave portion 31 is formed at substantially the center of the surface side of the heat insulating material 3, and a fixing material which is a hexagon nut 4 </ b> A having a screw portion is attached to the concave portion 31 to form the fixing portion 23. This is a configuration in which the step-like overlapping portion 32 and the portion to be polymerized 33 formed at the end of each can be connected by being polymerized.
In FIGS. 1 and 2, the upper surface side is the front surface side, the lower surface side is the back surface side, and the concrete placing surface side.

Among the exterior materials 2I and 2II, the exterior material 2I shown in the lower part of FIG. 2C is configured to include a space portion 23 on the back surface side of the face plate portion 21 serving as a finished surface. A protrusion 211 that protrudes to the surface side in a substantially T-shape is provided, and is an aluminum extrusion mold member provided with connecting portions 22A and 22B at opposing edges. A space 23 is formed adjacent to the connecting portion 22A on one side (right side in the drawing) and the side (left side in the drawing) is open. Specifically, the space portion 23 refers to a substantially U-shaped space surrounded by a portion extending from the face plate portion 21 and a substantially L-shaped piece formed so as to protrude to the back surface side.
As shown in the upper part of FIG. 2 (c), the exterior material 2II is substantially the same as the exterior material 2I with respect to the configuration of the face plate portion 21. Is an aluminum extrusion mold material provided with connecting portions 22C and 22D.
Although the connection portions 22A to 22D are not described in detail, the connection portion 22B of the exterior material 2I and the connection portion 22C of the adjacent exterior material 2II are engaged and connected, and the exterior is adjacent to the connection portion 22D of the exterior material 2II. The connecting portion 22A of the material 2I is engaged and connected. ,

As shown in the right side of FIG. 1 (b) and FIG. 3 (a), the heat insulating material 3 uses a synthetic resin foam face material that is a single-layer rigid polyurethane foam, and the upper part is open at the approximate center of the surface side. A groove-like recess 31 is formed, and at one end (right side of the drawing), a step-like overlapping portion 32 is formed by cutting away the lower part in the thickness direction, and at the other end (left side of the drawing). Is formed with a portion 33 to be polymerized with the overlapping portion 32, which is cut out in the thickness direction.
The recess 31 is fitted (freely fitted) with a frame-shaped portion forming the space 23 of the exterior material 2I, the connection portion 22A, and the connection portion 22D of the exterior material 2II.
The connecting portion 32 and the connected portion 33 can be connected by being overlapped, and are configured to form a concave space 31 ′ that opens upward in the connecting portion, and the concave space 31 ′ includes the concave portion Similarly to 31, the frame-like portion forming the space 23 of the exterior material 2 </ b> I, the connection portion 22 </ b> A, and the connection portion 22 </ b> D of the exterior material 2 </ b> II are fitted (freely fitted).
In the first embodiment, as described above, two kinds of exterior materials 2I and 2II are attached to the integral heat insulating material 3 two by two, so that a concave portion 31 is formed at the connection portion with the adjacent form panel 1 in the approximate center. A concave space 31 'is formed. In addition, through-holes 311 penetrating front and back are provided in the concave portion 31 and the concave space 31 ′.

Then, in order to lay and connect the two kinds of exterior materials 2I and 2II in parallel on the surface of the heat insulating material 3, the face plate portions 21 of the exterior materials 2I and 2II are bonded to the surface of the heat insulating material 3. At the same time, the connection portion 22A on one side of the exterior material 2I is engaged with the connection portion 22D on the other side of the exterior material 2II, and the connection portion 22B on the other side of the exterior material 2I is connected to the connection portion on one side of the exterior material 2II. Engage with 22C.
As described above, the connection of the exterior materials 2I and 2II is by engagement, and is elastically engaged with the configuration in which each face plate portion 21 is bonded to the surface of the heat insulating material 3. Become.
In the first embodiment, since the exterior materials 2I and 2II, which are aluminum extrusion molds, can be connected by engagement, the exterior material is not bonded to the heat insulating material 3 as shown on the left side of FIG. Since 2I and 2II can be engaged and connected to each other, the form panel 1 as shown in FIG.
In this way, the formwork panel 1 having a configuration in which a total of four kinds of exterior materials 2I and 2II are disposed on the surface of the heat insulating material 3 is formed.
In the first embodiment, since a total of four exterior materials 2I + 2II + 2I + 2II can be regarded as one exterior material, in FIG. 3 (b), FIG. 4, FIG. Material 2 is assumed.

The mold panel 1 is provided with two space portions 23, and a fixing material which is a hexagonal nut 4 </ b> A having a screw portion is attached to the space portion 23 to form a fixing portion. In the illustrated embodiment, the cushioning material 4b is disposed on the outer side (upper side in the drawing) of the hexagon nut 4A.
Therefore, as shown in FIG. 1A, the rod-shaped member 5A, which is a rod-shaped bolt material, can be screwed and connected to the fixing portion 4A from the back surface side of the heat insulating material 3. As this rod-shaped member 5A, a spacing member called a separator was used.
This spacing member is connected to a cylindrical member 5c made of synthetic resin via a hook-like material 5b, with a rod-like member 5A whose tip is screwed into a screw portion (not shown) of the square nut 4A in the space 23. Further, a cylindrical member 5f having a rod-like member 5e disposed therein is connected via an intermediate connecting portion 5d having a diameter larger than that of the cylindrical member 5c. It is the structure which reaches to the mold 6 on the other side. And this space | interval holding member can be divided | segmented in the said intermediate | middle connection part 5d, and after placement of concrete, the rod-shaped member 5e of the other side can be extracted and reused, and formation of a thermal bridge is prevented. be able to. In addition, since this rod-shaped member 5A has penetrated the superposition | polymerization part (polymerization part 32 and to-be-polymerized part 33) of adjacent heat insulating materials 3 and 3, connection of heat insulating materials 3 and 3, ie, adjacent formwork This also contributes to the connection of the panels 1 and 1.

Thus, since the formwork panel 1 of this invention can connect the adjacent exterior materials 2 and 2 by engagement and can connect the adjacent heat insulating materials 3 and 3 by superposition | polymerization, the adjacent formwork panels 1 and 1 The connection strength between them becomes high.
In the formwork panel 1 shown in FIG. 3 (b), a through hole 311 is formed at the substantially center and one end (left side in the drawing). The member 5A and the hook-shaped material 5b are disposed, and are screwed into a hexagon nut 4A in the fixing unit 23 (not shown) so as to protrude in an upright manner.

4 and 5 show a state where the formwork panels 1 and 1 of the first embodiment are connected in series in the horizontal direction.
First, FIG. 4 shows a state in which the formwork panel 1 is to be further connected to what has already been connected to the two formwork panels 1 and 1.
In the structure in which the two formwork panels 1 and 1 shown on the left side of FIG. 4 are connected, not only the substantially central through hole 311 of each formwork panel 1 but also the connection part between the formwork panels 1 and 1. The rod-shaped member 5A and the hook-shaped material 5b are also disposed in the insertion hole 311 located at the position. This is because, as already described, when the formwork panels 1 and 1 are connected in series in the horizontal direction, the rod-shaped member 5A also contributes to the connection of the formwork panels 1 and 1.
Therefore, in order to connect the form panel 1 further, the adjacent exterior materials 2 and 2 are connected by engagement, the adjacent heat insulating materials 3 and 3 are connected by polymerization, and the rod-shaped member 5A is further connected to the through hole. 311 is attached from the back side, and the tip thereof is screwed with a hexagon nut 4A in the fixing unit 23 (not shown), so that it can be connected in series in the lateral direction. As a result, the formwork structure shown in FIG. Can be obtained.

  Thus, the formwork panel 1 of the present invention can be used as a formwork by connecting it in series in the lateral direction easily and with high connection strength, and at the end of the rod-like member 5A attached to the heat insulating material 3 side. As shown in FIG. 1, the rod-like member 5 e and the cylindrical member 5 f may be connected to form a spacing member, and concrete may be placed between the mold 6 on the other side.

At that time, even if noro leaks from the connection part between the adjacent form panels 1, 1, the connection part of the heat insulating materials 3, 3 is polymerized stepwise, so the leakage flow path is refracted It becomes. Moreover, since the exterior material 2 is pulled inward by the rod-shaped member 5A and the heat insulating material 3 is pushed outward from the inside by the concrete placing pressure, the density of the polymerized portion is increased by receiving pressure from both sides. It is possible to eliminate as much as possible by squeezing the refraction-like gaps that rotate. Even if the exterior material 2 is pulled inward by the rod-shaped member 5A, the cushioning material 4b is disposed outside the hexagon nut 4A, so that the hexagon nut 4A may be pressed against or damaged by the exterior material 2. Absent.
Furthermore, even if the slot enters the space 23 through the rod-shaped member 5A, the space 23 is provided on the back side of the face plate 21, so that leakage of the slot can be prevented and the face plate 21 is soiled. It can be held beautifully and can be used as an exterior material as it is without requiring troublesome processing and finishing work.

  In the first embodiment, the hexagonal nut 4A, which is a square nut, is attached to the space portion 23 as a fixing material and used as a fixing portion. Therefore, a general-purpose nut can be used as the fixing material, and the head has a square shape. Therefore, rotation (spinning) is prevented even when the rod-shaped member 5A is attached.

  In the first embodiment, the through holes 311 penetrating the front and back surfaces of the heat insulating material 3 are opened at a predetermined interval, and the rod-shaped member 5A can be inserted into the through-hole 311. Therefore, the rod-shaped member 5A is inserted into the through-hole 311. The formwork panel 1 can be laid in a state of protruding, and after laying at a predetermined position, the rod-like member 5A may be tightened, and the connecting operation can be carried out extremely easily.

  Moreover, in this 1st Example, since the vertical striped finish surface provided with the protrusion 211 which protrudes from the faceplate part 21 in a substantially T shape is obtained, this protrusion 211 is utilized functionally or designally You may make it do.

  The formwork panel 1 ′ of the second embodiment shown in FIG. 6 is integrated by attaching (bonding) two kinds of exterior material 2III made of a metal face material to the surface of the integral heat insulating material 3 ′. It is the composition which becomes.

  The exterior material 2III is provided with a face plate portion 25 serving as a finished surface and connection portions 26 and 27 at opposite ends of the face plate portion 25, and the connection portion 26 located at one end portion is bent to the back surface side. A substantially vertical bent piece and a substantially horizontal overlapping piece bent further inward, and has a space portion 23 ′ on the back side of the face plate portion 25 that is released inside. . The connecting portion 27 located at the other end has a substantially L shape having a substantially vertical bent piece bent to the back surface side and a substantially horizontal polymer piece bent further outward. Here, “one” refers to the right side of the drawing, and “the other” refers to the left side of the drawing. In order to connect the exterior materials 2III and 2III on the surface of the integral heat insulating material 3 ′, the polymerized piece of the connecting portion 26 is polymerized and connected to the polymerized piece of the connecting portion 27.

  The heat insulating material 3 ′ is exactly the same as the heat insulating material 3 of the first embodiment except that the convex portion 34 is provided on the end surface in the vertical direction, and the upper part is approximately at the center of the surface side. A groove-shaped recess 31 to be released is formed, and one end (right side in the drawing) is formed with a step-like overlapping portion 32 having a lower portion in the thickness direction cut away, and the other end (left side in the drawing). Is formed with a portion 33 to be polymerized with the overlapping portion 32, with the upper portion in the thickness direction cut away.

Also in the second embodiment, similarly to the first embodiment, two space portions 23 ′ are provided in the mold panel 1 ′, and the space portion 23 ′ is provided with a hexagon nut 4A having a screw portion. Since a fixing member is attached to form a fixing portion, a rod-shaped member 5A, which is a rod-shaped bolt material, is connected to the fixing portion 4A by screwing from the back surface side of the heat insulating material 3 '. As in the first embodiment, this also contributes to the connection between the heat insulating materials 3 ′ and 3 ′ between the adjacent mold panels 1 ′ and 1 ′.
Moreover, in FIG. 6, the position where the rod-shaped member 5A is disposed is indicated by a one-dot chain line. As is apparent from this position, in the second embodiment, the adjacent heat insulating materials 3 ′ and 3 ′ are disposed. This contributes not only to the connection between each other but also to the connection between the exterior materials 2III and 2III. Of course, this also contributes to the connection of the exterior materials 2III and 2III on the surface of the heat insulating material 3 ′.
