Description

  The present invention provides a formwork panel that can be used as an exterior material as it is without requiring finishing after placing concrete, and that can also prevent leakage of noro from the connecting portion between adjacent panels, and concrete It relates to the construction structure of the wall.

  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. ) 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 a formwork panel that can be used as it is as an exterior material without the need for finishing after placing concrete, and can also prevent leakage of noro from the connection part between adjacent panels, And it aims at proposing the construction structure of a concrete wall.

  The present invention has been proposed in view of the above, and is a formwork panel including a decorative material and a heat insulating material attached to the inside of the decorative material, the decorative material including a face plate portion serving as a finished surface, And having a connection part formed at both ends of the face plate part and a fixing part having a screw part formed on the back side of the face plate part, and adjacent decorative materials can be connected by engagement or fitting. The present invention relates to a formwork panel characterized in that a rod-like member disposed in a concrete placement space can be screwed and connected to a screw portion in the fixing portion from the back side of a heat insulating material.

  The present invention also proposes a formwork panel in which the decorative material is made of an extruded mold material.

  According to the present invention, there is provided a mold panel in which a space portion is provided on the back 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. I also propose.

  Further, according to the present invention, in the form panel, the inner side of the heat insulating material is regulated by a pressing member that is locked to the rod-shaped member, that is, a pressing member such as a hook-shaped material is attached to the rod-shaped member to sandwich the heat insulating material. We also propose a formwork panel, which is characterized by being held down.

  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.

The formwork panel according to the present invention includes a connecting portion formed on both ends of a face plate portion, which is a finished surface, and a fixing portion having a screw portion formed on the back side of the face plate portion. Adjacent decorative materials can be connected to each other by engagement or fitting, and a rod-like member disposed in the concrete placement space is connected to the screw portion of the fixing portion of the heat insulating material. It can be connected by screwing from the back side. In addition, since the fixing part is formed on the back side of the face plate part, even if the rod enters the fixing part through the rod-shaped member from the concrete placement space, the fixing part leaks to the surface of the face plate part. Is prevented. Furthermore, since the connection portion and the fixing portion can be provided separately, there are few restrictions on molding, and any aspect can be applied.
Therefore, sufficient strength can be obtained as a decorative material, distortion does not occur due to concrete placing pressure, etc., and further, molding means can be obtained so that connection means such as engagement can be reliably performed. .
In this way, the formwork panel of the present invention can easily connect adjacent formwork panels, and can also prevent leakage of noro from the connection part of the formwork panels. There is no need to process (wipe off) and it 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.

  Further, when the decorative material is made of an extruded mold material, the connecting portion and the fixing portion can be formed with a simple shape configuration, and a formwork panel that can be used as a formwork can be formed.

  Further, the inside of the heat insulating material is regulated by a pressing member that is locked to the rod-shaped member, that is, when a pressing member such as a hook-shaped material is attached to the rod-shaped member and the heat insulating material is pressed in a sandwiched manner, the concrete The formwork panel is integrated in the period until it is placed.

  Further, when a space portion is provided on the back side of the face plate portion and a fixing member having a screw portion is attached in the space portion to form the fixing portion, the fixing portion can be easily formed.

Furthermore, the construction structure of the concrete wall of the present invention uses the formwork panel having the above-described structure as a formwork for the concrete formwork method. As described above, various insulation materials and decorative materials are appropriately selected. The concrete wall of the specification can be easily and inexpensively constructed.
For example, by using a high-strength metal face material as a decorative material, it can be applied to a wall having a large area with strength against the concrete placing pressure. In addition, since it is possible to use a metal face material that also serves as a decorative material, it is not necessary to arrange a separate decorative material on the surface, and construction (construction) of the outer wall is also performed on a site (construction site) where no scaffolding can be assembled. The formwork panel can be used as it is as an exterior cosmetic.

It is sectional drawing which shows only the cosmetics of other one Example (5th Example), (e) It is sectional drawing which shows only the cosmetics of other one Example (6th Example) of the formwork panel of this invention. is there.

  In the formwork panel of the present invention, a decorative material is disposed on the surface of the heat insulating material, a fixing portion having a screw portion is formed on the back surface side of the decorative material, and the back surface side of the heat insulating material is formed on the fixing portion. The rod-shaped members can be connected by screwing.

The heat insulating material and the decorative material constituting the formwork panel are separately molded, and can be appropriately selected to have a desired configuration. For example, if it is going to set the intensity | strength and other characteristic of the whole formwork panel to a desired level, these heat insulating materials and a decorative material can be selected suitably, and a desired characteristic can be obtained.
Below, a heat insulating material and a decorative material are each demonstrated.

  As the heat insulating material, heat insulating materials of various materials can be applied. For example, the heat insulating material 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 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-shaped member can be inserted into the through holes. In this case, the formwork panel can be laid in a state in which the rod-like member is protruded in the through hole, and the rod-like member may be tightened after being laid at a predetermined position, so that the connecting operation can be performed 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.

The decorative material is not particularly limited in terms of material and molding method, but it is desirable to use an extrusion mold material such as aluminum, and the thickness is not particularly limited. More preferably, the thickness is 6 mm or more, and the strength is such that the surface will not be distorted or deformed even when some stress such as concrete pouring pressure is applied. However, because of the molding problem, the decorative material made of this extrusion mold is a molded product with a width of up to about 200 mm. Therefore, a plurality of decorative materials are usually added to the heat insulating material formed to a width of nearly 1 m. It becomes.
In addition, as this decorative material, a kind of decorative material may be used, or two (or more) decorative materials may be used. In the case of two (or more) decorative materials, the width may be different. . However, since the specification using three or more kinds of cosmetics is very special from the viewpoint of manufacturing and management, the following description will be made assuming that one or two kinds of cosmetics are used. Even if two types of decorative materials are used, it is not necessary to provide a space in each decorative material, and it is only necessary to provide at least one of them. That is, when two types of decorative materials are used, there are many specifications in which one decorative material is provided with a space portion and the other decorative material is not provided with a space portion.
And this decorative material may be provided with a single decorative material for the integral heat insulating material, but in the case of an extrusion mold material, due to the above-mentioned problem of the molding width, Since a plurality of decorative materials are attached, a plurality of types of decorative materials are attached to an integrated heat insulating material, or two types of decorative materials are added to an integrated heat insulating material one by one, or a plurality of pieces It will be attached.

Further, the decorative material includes a connecting portion that can be connected to both ends of the face plate portion to be a finished surface, that is, at least a pair of opposing edges (for example, up and down, left and right), and the connecting portion is connected by engagement or fitting. To do. When the decorative material is made of an extrusion-type material, high strength and elasticity are also given to this connecting portion, so that the assembled state such as engagement or fitting is maintained elastically and stably, and the connection is easy. Can do.
Even when two kinds of decorative materials are used, the connecting portions provided on the respective decorative materials may be the same or different.
In addition, since the said faceplate part turns into a finishing surface, it may be substantially flat shape and what was attached | subjected the designability (decorative property) suitably, and the shape in particular is not limited.

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 a decorative material with an extrusion mold material as mentioned above, it can respond easily also to the aspect which shape | molds a thick-walled 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, as shown in the illustrated embodiment to be described later, a space portion that opens sideways is provided on the back side of the face plate portion, and a configuration using a general-purpose nut as a fixing portion in the space portion, that is, a female screw portion is provided. In this case, a bolt material can be used as the rod-shaped member, and the head of the general-purpose nut is square, so that the rotation (rotation) is prevented when the rod-shaped member (bolt material) is attached. It will be a thing.
Further, as shown in the illustrated embodiment to be described later, a substantially rectangular space portion that is open on the side surface or the back surface side is provided on the back surface side of the face plate portion, and a fixing material having a screw portion is attached in the space portion to form a fixing portion. May be. 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. Note that, as described above, when the decorative material is molded by an extrusion mold material, the fixing material has a high holding (carrying) strength.

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 a decorative material and a heat insulating material, or the whole intensity | strength.

  Moreover, the formwork panel of this invention which each arrange | positions each of these members is manufactured by the following formation processes, an integration process, and a connection process. In addition, when attaching one kind of decorative material to the integral heat insulating material, the connection structure is one kind, but here two kinds of decorative materials each having a different connecting portion on the integral heat insulating material, An example of attaching a total of 4 sheets is shown.

-Molding process First, as for the cosmetic material, there are two types of cosmetic materials, a cosmetic material having a fixing portion (for convenience, the first cosmetic material) and a cosmetic material not having the fixing portion (for convenience, the second cosmetic material). And is formed so that it connects with the connection part of an adjacent edge at the both ends of each decorative material. That is, the connection part A on one side of the first decorative material can be connected to the connection part D on the other side of the second decorative material, and the connection part B on the other side of the first decorative material is connected to one side of the second decorative 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.
Further, since a fixing portion is provided on the back side of the first decorative 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, as for the heat insulating material, in the case of a single layer as in the illustrated embodiment described later, a space portion of the decorative material is provided on the heat insulating material side, and a concave portion for fitting the space portion (outer portion forming the space portion) is provided. Therefore, it can arrange | position, without producing the shift | offset | difference of a cosmetics, etc.

-Integration process Although the said 2 types of cosmetics are laid in parallel on the surface of the said heat insulating material, what is necessary is just to connect suitably combining according to the aspect of each connection part of 2 types of cosmetics.
The heat insulating material and the decorative material are integrated to such an extent that they do not separate or shift when the formwork panel is used, but the means is not limited. For example, the back surface of the face plate portion is bonded to the heat insulating material surface. 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 portions A and D and the connection portions B and C, assuming that they are connected by engagement or fitting, as described above, when the decorative material is made of an extrusion mold material, The assembled state is maintained elastically and stably, forming an elastic engagement portion or an elastic fitting portion. And, on the integrated heat insulating material, two kinds of decorative materials are installed, two each, for a total of 4 sheets, so on the integrated heat insulating material, the connection structure of one connecting portion 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 decorative materials such as metal face materials on the surface of a heat insulating material, and connects adjacent formwork panels.
