Description

[Detailed Description of the Invention] (Industrial Application Field) This invention constitutes an outer formwork for a formwork into which concrete is poured, and also provides external insulation for a concrete wall constructed by pouring concrete. This invention relates to an exterior device that also serves as a formwork.

(Prior Art) The present applicant has proposed, in Japanese Patent Application No. 117B26/1983, that at least one side of the formwork into which concrete is poured is constructed with predetermined plate thicknesses, widths, and heights in multiple stages in the vertical direction. (e.g. concrete, glass fiber-impregnated GR)
(C, FRC containing iron fibers, resin concrete using resin as a binder instead of cement, etc.), and the concrete walls constructed with poured concrete are covered with the above-mentioned molded plates. We proposed construction methods for external walls, partition walls, retaining walls, fences, and other concrete walls.

(Problems to be solved by the invention) However, depending on the above method, internal condensation is unlikely to occur.
It is not possible to construct walls of buildings with external insulation, which is desirable from various aspects such as energy saving, improved livability, and improved building durability.

(Means for Solving the Problems) Therefore, the present invention relates to an exterior frame/exterior device for constructing a wall of an externally heat-insulated building by using the construction method of the prior proposal. At the same time as installing the heat insulating material, a molded concrete plate integrally equipped with a hook that penetrates the heat insulating material from the back side and protrudes a certain length, and a molded plate that passes vertically through the hook of the molded board and is placed on the lower molded plate. The upper forming plates are arranged vertically and the connecting tool constitutes the outer formwork of the formwork into which concrete is poured. The present invention is characterized in that a jig is provided that penetrates the heat insulating material and abuts the back surface of the molded plate, and passes the coupling tool between the back surface and the inner surface of the tip of the hook.

(Function) The hook, which integrally projects a certain length from the back surface of the molded plate, penetrates the heat insulating material attached to the back surface and projects from the back surface of the heat insulating material. A jig that penetrates the heat insulating material and comes into contact with the back surface of the molded plate is fitted into the protrusion of this hook, and the jig creates a space between the back surface and the inner surface of the tip of the hook in which the coupling tool is passed vertically. secure. Therefore, the connecting tool is brought into contact with the back surface of the jig and the inner surface of the tip of the hook, and passed vertically, and the upper molding plate is placed vertically on top of the lower molding plate, and concrete is poured into the formwork between them. The outer formwork can be constructed.

(Example) In the drawings, a molded plate according to the present invention is made up of a substrate made of concrete or the like as a surface, and a heat insulating material attached to the surface by adhesive or the like. Insulation materials include insulation boards made of Styrofoam etc. to a certain thickness, rock wool,
Any material can be used, such as a glass cool mat or a board formed by adding adhesive to the mat.

This board has reinforcing materials such as laths and vertical and horizontal reinforcing bars embedded inside it, and from a predetermined position on the back side, a V-formation that penetrates through the insulation material is molded with concrete so that the U-shaped hook 3 protrudes a certain length. As an example, its size is about 21M thick, about 1s high, and about 15cm wide. The 7tsuk 3 may be formed by bending a part of the horizontal reinforcing bars to be embedded in the substrate when forming the board, or by embedding a base part in the board separately from the above reinforcing bars. Good too. The protruding position of the hook 3 is determined so that when the molded plates are arranged vertically, the hooks of the upper and lower molded plates are aligned vertically.
For example, as shown in the figure, the top and bottom are set inward from each end by one length of the width of the molded board, and even when the upper row is lined up on top of the lower row with a potato joint, it is shifted sideways by the width i. It is preferable that the upper tier be vertically aligned even when the upper tier is placed on top of the lower tier with broken joints.

In addition, the heat insulating material is attached to the entire surface of the base plate of the molded plate, and the hook 3
penetrates the crack provided at the hook protruding position of the insulation material and protrudes from the back surface of the insulation material.

In order to align the surfaces or outer surfaces of the substrates of the upper and lower molded plates arranged vertically in a common vertical plane, legs 7 are provided which have slits 7' and pierce the heat insulating material, as shown in FIG.
Using a jig equipped with b, fit the jig 7 into the hook 3 from the tip through the slit 7', pass the insulation material through the leg 7b and contact the back side of the board, and connect the back side of the jig 7 and the hook 3 with the leg 7b. Secure a space between the inner surface of the tip and the inner surface of the tip for passing the coupling tool in the vertical direction. This jig does not need to be welded to the hook if the leg 7b is held by a heat insulating material.

Next, FIG. 2 shows an example of a connecting tool that is passed vertically through the hooks of the lower and upper molding plates arranged vertically to form an outer form into which concrete is poured. These can be formed by bending a steel wire with a diameter of about 10 cm into a predetermined shape, and the lower half is buried in the foundation or attached by welding to a reference frame fixed to the top of the foundation, and the upper half is Insert the folded part DA' into the hook under the bottom molding plate, and the figure B has folded parts +' and lI' at the top and bottom, and the lower folded part is inserted between the molding plates of the lowermost stage. Insert it into the hook on the top of the board, insert the folded part at the top into the hook under the molded board on the upper tier, and use it to line up the upper tier on top of the lower tier. These coupling tools have a straight part DA that comes into contact with the back surface of the jig when inserted into the hook 3, and a folded part q' is bent diagonally from the end of the straight part DA and inserted into the hook 3. As it is pushed in, the folded portion is somewhat compressed by the inner surface of the tip of the hook, and its free end approaches the straight portion 1ILs.

FIG. 1 is a perspective view of an example of a situation in which an externally insulated wall of a building is constructed using the apparatus of the present invention.
J-) The outer formwork of the formwork into which C is poured is made by arranging the molding boards vertically, and placing 7 pieces J on the back side in Figure 2 (B) and C).
It is constructed by connecting the molded plates of the upper and lower stages to each other by passing a connecting tool shown in the upper and lower sides.

In this ~, the same formwork is also molded with similar concrete, etc., and interior molded plates A' consisting of substrates/' with hooks 3 protruding from the back side are vertically arranged, and hooks 3 on the back side are similarly formed.
The molded plates of the upper and lower stages are connected to each other by passing a connector in the vertical direction.

In this way, the inner formwork and the forming plate A' are the same size as the forming plate of the outer formwork.
When arranging the lower tier on top of the upper tier using connectors, connect two of the connectors in Figure 2(B) in an H-shape facing each other with the intermediate connecting part b as shown in Figure 2(C). By using a joint/connector as shown, it is possible to vertically line up the upper stage on each lower stage of each of the molding plates of the outer formwork and the inner formwork, and to connect both molding plates at a predetermined interval at the same time. In the figure of this coupler/connector, the upward folded parts f and al are pressed when inserted diagonally from the straight part 〇〇 into the folded part 7, similar to the folded parts f and al in Fig. 2 and B in the same figure. It looks like this. But downward,
The folded part ``Hiroshi'' connected by the intermediate connecting part ``Hiroshi'' is folded back approximately parallel to the straight part DAα, and when inserted into the hook, it fits perfectly and holds the forming plates of the outer formwork and inner formwork in place. Concatenate at intervals of . To arrange the upper tier on top of the lower tier, use the second
You may use the clip shown in Figure (C), or you can use the clip shown in Figure 2 (B).
The clip shown in FIG. 2 and the clip shown in FIG. 2(C) may be used together.

To do this, when constructing the foundation B, for example, as shown in Fig. 2 ( A
) as shown in Fig. 1.), or as proposed in Japanese Patent Application No. 56-68220, based on a reference frame having two rows of upwardly facing couplings ≠... At the time of construction, it is fixed horizontally on the upper surface of the foundation, or it is fixed horizontally on the created foundation using vertical reinforcements rising from the foundation, and the bottom of each of the outer formwork and inner formwork is formed. Insert the upward connecting tool on the foundation into the lower 7 pieces 3 protruding from the back of the board's board, and create a vertical strip that rises from the foundation! And, with the horizontal reinforcements 6 welded or tied together and attached laterally, the two molded plates A' are lined up with a constant distance between the back sides, and each time they are set up and lined up, or The process of placing ready-mixed concrete C in one or more rows or a small number at the above-mentioned intervals is repeated to construct an outer wall of a building of a desired height.

Incidentally, it is preferable to place the concrete before the concrete placed underneath has not yet hardened.

(Effects of the Invention) In the molded plate of the present invention, even if the heat insulating material is attached to the entire back surface of the substrate, the jig 7 fitted into the hook 3 protruding from the back surface of the heat insulating material can be used to connect the inner surface of the tip of the hook 3. A space is secured in between to pass the connector. Therefore, by covering the entire back side of the board with a heat insulating material, the heat insulating effect according to external insulation theory can be achieved.In other words, when the outdoor temperature starts to drop from evening to night, the heat insulating material λ reduces the flow of heat toward the outdoors through the outer wall. Most of the stored heat energy accumulated in the outer wall due to sunlight flows toward the room, preventing a sudden drop in room temperature and preventing internal condensation. In order to connect the molded plates of the upper and lower tiers vertically by contacting the back side of the board and the inner surface of the tip of the 7-tsuku J in the vertical direction through the hook 3, It fits perfectly and doesn't stick out or pull in unsightly.

In addition, since the molded board substrate faces the outside of the building and the insulation material is hidden behind it, there is no need for exterior work to protect the insulation material, and it also eliminates the need for exterior construction to protect the insulation material. However, it can be used without any problem since it is buried in the wall.

Of course, this molded board can be used to easily and quickly construct externally heated external walls of buildings without the need for removal work after wall construction, and
The hooks and connectors are buried in the poured concrete to protect it from corrosion, while the hooks and connectors securely bind the molded board and insulation material to the wall, and also connect the molded boards to each other on the upper level. The reinforcing materials such as laths and reinforcing bars buried in the lower board L are originally unrelated to each other, but the ready-mixed concrete C has a connecting tool connecting the nine molded board members in the upper and lower stages.
By being buried in the molded concrete and integrally connected with the ready-mixed concrete together with the molded plates in the upper and lower tiers, the reinforcing materials inside the 9 molded plates in the upper and lower tiers, which were originally unrelated, can be strengthened through connectors and connectors. It becomes a strength member of the constructed wall and effectively reinforces the strength of the wall.

Furthermore, even if the heat insulating material melts and disappears due to a fire, etc., the molded plates of the upper and lower tiers are connected to each other by a connecting tool that contacts the back surface of the jig and the inner surface of the hook. Because of this, it will not collapse, and by injecting a foaming agent into the space where the insulation has disappeared, it can be made to foam and regenerated into an external wall.
