BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a streamlined formwork / interior basework heat insulation panel related to concrete formwork work to interior groundwork work in construction work, and this formwork / interior base work heat insulation panel. It relates to the construction method used.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. A wide variety of conventional concrete formwork members are used, but in general, plywood, metal formwork panels, plastic panels,
Hard fiber boards are used. In the construction method, the mold assembly as shown in FIGS. 1 and 2 is performed. In the figure, 1 is a plywood form,
Reference numeral 2 is a thick inner edge, 3 is a foam tie, 4 is a thick outer edge, and 5 is a separator.

In recent years, energy saving has been called for, and buildings and houses with high airtightness and high heat insulation have been built. However, since heat insulating materials are always used in such buildings, the post-adhesion method (after the construction of the skeleton) A method of adhering a heat insulating material to the surface) ・ A driving method (a method of attaching a heat insulating material to the inside of a formwork panel and removing only the panel after building the frame) ・ Injection type method (in-situ foaming type between the body and the finishing plate) It is constructed by the method of injecting heat insulating material. In the driving method, which seems to be the most rational among them, the heat insulation material and the wood wool fiberboard / new building material board are used as a weirboard, and while holding the panel with a shackle Assemble and fix the edges. After the concrete is poured, the concrete panels and supports are dismantled after curing and hardening, and interior groundwork is performed.

Regarding the wall-covering work of the interior groundwork, the following construction methods are carried out. 1. The pillars, studs, and furring strips are assembled from wood, and the boards are nailed to these members. 2. Assemble a lightweight steel frame and use tapping screws or clips to stop the board. 3. Apply the adhesive in a dumpling pattern, crimp the board to it, and stop. 4. The wooden bricks 12 are adhered to the positions of the horizontal furring strips 8, and the vertical furring strips 9 are grid-assembled thereto, and then the interior board 11 is fixed with nails 10 such as flat-head spiral nails.

Generally, the mounting method as shown in FIG. 3 is performed. In the figure, 8 is a horizontal furring strip, 9 is a vertical furring strip, 10 is a nail such as a flat-head spiral nail, 11 is an interior board, 12 is a wooden brick,
13 is an adhesive. Looking at the work contents from the formwork construction to the interior groundwork construction by the conventional method, mounting the heat insulating material on the concrete panel → building the formwork → concrete placing → dismantling and scraping off timbers, piers and panels → foundation material framework → Construction is done in the order of board mounting → finishing.

[0006]

The problem of the material and the construction method from the formwork to the interior groundwork is that the dam in the concrete formwork has sufficient rigidity so as not to be deformed or destroyed. In addition, strength is required, and it is also required to secure moisture until the concrete hardens and to protect it from the outside air. In addition, the heat insulating material panel may be used directly as a dam, but in this case, the strength of the heat insulating material panel itself is weak, so it is necessary to take a large thickness or to combine it with other panels in a composite manner. It becomes high.

[0007] From the viewpoint of construction, it is easy to assemble and dismantle claps, supports, and binding materials, and from an economic point of view, the cost of formwork construction is large in terms of the amount of transportation and extension workers, and the cost of building construction 20-3
Since it occupies 0%, rationalized members and construction methods are required. Also, in the interior groundwork after the construction of the skeleton, it is necessary to bring in the members, assemble the pillars, studs, and furring strips on the surface of the body to fix the board, which requires material costs, transportation costs, and labor costs. In addition, there are many problems regarding the storage and delivery of materials, and systematic members and construction methods are required.

The present application has been made in view of the above problems of the prior art, and an object of the present application is to provide a device capable of solving the above problems.

[0009]

In order to achieve the above object, the present invention is as follows. In the present invention, as a result of various investigations in order to eliminate the above-mentioned drawbacks, a heat insulating material panel A which also serves as a formwork / interior base was obtained. That is, by fixing and integrating the composite reinforcing member 7 with the foamed plastic heat insulating plate 6, the rigidity can be increased and the performance as a concrete dam can be provided, and the composite reinforcing member 7 can be used as a thick material. As a result, the assembly and disassembly work could be simplified.
The heat insulating material panel A itself, which is also used as a formwork / interior groundwork, is used as a heat insulation material after the construction of the skeleton, and even in the interior groundwork work, the interior reinforcement board can be fixed by substituting the composite reinforcement material 7 as the groundwork material. It was done like this.

Specifically, the foamed plastic heat insulating plate 6
(Expanded polystyrene, expanded polyethylene, expanded polyurethane, expanded phenolic resin and other expanded plastic plates)
In order to reinforce the strength of the above, a vertical groove 6A having a concave cross-section is formed on the surface of the foamed plastic heat insulating plate 6, and a square rod-shaped material having a high rigidity is inserted into the groove 6A as a composite reinforcing material 7. It is fixed with an adhesive agent 14 that does not attack. The above-described groove processing may be performed on the mold of the molding plate or may be processed after molding.

Any material can be used for the composite reinforcing material 7 as long as it has high rigidity, but metal materials, plastic materials, woods, and composite materials thereof can be considered, but the weight and cost of the reinforced panel are Considering the workability, it is possible to use a material obtained by kneading a waste plastic material or the like, which has been attracting attention in recent years due to environmental problems and the like, with a thermoplastic resin, a foaming agent, ceramics, glass fiber, etc. and injection molding. However, the material composition is the thickness, strength, deflection of the foamed plastic insulation board,
It must be configured in consideration of the outer edge thick spacing and the like.

As shown in FIG. 7, the composite reinforcing member 7 has a ridge 7B protruding laterally from the rear end of the side surface of a square bar 7A made of a material having a low density to enable nailing or the like. ing. Particularly, when rigidity is required, as shown in FIGS. 8 and 9, the reinforcing material 7C, 7D having rigidity such as an aluminum channel material is integrated inside the rear surface of the composite reinforcing material 7. As a method of this integration, there are a method of using an adhesive and a method of inserting a metal or the like during injection molding.

The composite reinforcing member 7 has holes for foam ties,
Mark 7E as a guide for dimensions, die for adjusting the unevenness 7
Workability will be further improved by performing processing such as F. In the panel in which the composite reinforcing material 7 is fixed to the foamed plastic heat insulating plate 6 as described above, the breaking strength and the amount of deflection of the entire panel can be remarkably improved without increasing the thickness.

Further, by inserting the composite reinforcing material 7 in the space between the thick ends, a lightweight and easy-to-handle formwork that can withstand the lateral pressure at the time of concrete driving with only the thick outer ends without the thick inner ends.
A heat insulating material panel A that also serves as an interior substrate can be manufactured. When the foamed plastic heat insulating plate 6 is manufactured, it is useful to prevent slag after driving by processing the periphery of the foamed plastic heat insulating plate in an isometric shape, and the heat insulation performance can be fully exhibited by reliable adhesion. Like

Further, if the unevenness 6B, 6C is formed on the surface of the foamed plastic heat insulating plate 6, it becomes a ventilation layer to prevent dew condensation. After constructing the skeleton, use the composite reinforcing material 7 of the heat insulating material panel A that also serves as the formwork / interior groundwork as a base material to attach an interior boat with screws, nails, or attach the board directly to the heat insulation material portion with an adhesive or the like. Can be attached.

EXAMPLES Examples will be described with reference to the drawings. About Example 1 As shown in FIG. 10 and FIG. 11, the circumference was previously processed into an isometric shape with a thickness of 65 mm, a length of 1820 mm, and a width of 910 m.
m and a density of 32 kg / m ^{3 on} the surface of the foamed plastic heat insulating plate 6 made of expanded polystyrene heat insulating plate.
Square bar 7A (thickness 20 mm, length 1820 m) made of a low-expanded polystyrene resin square material formed by processing four vertical grooves 6A having a concave cross-section in a 27.5 mm pitch)
m, width 40 mm, density 800 kg / m ³ ) and the reinforcing mold material 7C (thickness 2 mm, length 1820 mm, width 40 mm) made of aluminum channel material are placed on the composite reinforcing material 7 and the adhesive (aqueous polyisocyanate) is placed. A heat-insulating material panel A, which was used as a formwork / interior substrate, was fixed at the factory.

Next, this heat-insulating material panel A, which also serves as a formwork / interior groundwork, is used in place of the weir board of the formwork, and has a height of 2730 m.
As shown in FIG. 4 and FIG. 5, a formwork of m, width 1820 mm, thickness 150 mm is installed, a separator 5 and a foam tie 3 are attached, and a single pipe with a diameter of 48.6 mm is used as the outer end thick 4 4.
After being provided at 55 mm intervals and fixed with a support, fresh concrete of slumps 15 to 16 was poured. In addition,
Mark 7E on the composite reinforcing material so that the outer thick pitch interval can be seen.
I put it on.

After the concrete is hardened and cured, the supporting work is removed, and the interior board 11 is driven by the nail 10 such as a flat-headed spiral nail into the composite reinforcing material 7 at a vertical pitch of 227 mm and a horizontal pitch of 455 mm as shown in FIG. It was As a result, no problematic deformation or crack was observed, and there was almost no slag. In addition, each process can be greatly simplified because it is possible to construct from the formwork work to the interior groundwork work without using concrete formwork panels, inner edges, and interior groundwork materials. In the figure, 1 is a plywood form, and 2 is a thick inner end.

About Example 2 A foamed plastic heat insulating plate 6 made of a polystyrene foam heat insulating plate having a thickness of 65 mm, a length of 1820 mm, a width of 910 mm and a density of 32 kg / m ³ , the periphery of which was previously processed into a scale.
Four vertical grooves 6A having a concave cross section are machined on the surface of the inner end at a thick interval (227.5 mm pitch), and a square rod-shaped body 7A (thickness made of a low-expanded polystyrene resin square material molded by an injection machine is formed. 20mm, length 1820mm, width 40mm, density 800
Kg / m ³ ) was placed and fixed with an adhesive (aqueous polyisocyanate system) to prepare a heat insulating material panel A that also serves as a formwork / interior base.

Next, this heat insulating material panel A, which also serves as a formwork / interior groundwork, is used in place of the dam of the formwork, and the height is 2730 m.
m, width 1820 mm, thickness 150 mm, and a square pipe (length 50 mm, width 50 m)
m, thickness 2.3 mm) as outer edge thick 4 at intervals of 300 mm and fixed with a support and then slump 15 to 16
I poured the green concrete. After the concrete was cured and cured, the supporting work was removed, and a plaster board adhesive was applied to the surface of the heat insulating material panel A that also serves as a formwork / interior base, and the interior board 11 was attached. As a result, deformation that causes a problem
No crack was observed.

The operation will be described together with the effects.

[0022]

Since the present invention is constructed as described above, it has the following effects. As is clear from the above description, according to the present invention, the composite stiffener having high rigidity is fixed to the surface of the foamed plastic heat insulation panel in the interval of the thick ends of the formwork, so that Since it is no longer necessary to use thick plates and inner edge materials, the work of transporting, assembling and disassembling them is reduced, and the construction period can be shortened, resulting in a significant cost reduction.

Further, since the foamed plastic heat insulating plate itself is attached to the body, the work of attaching the heat insulating material can be omitted. After constructing the skeleton, it can also be used as an interior lining material to attach the board to the skeleton, so interior lining work can be omitted. Also, in normal interior work, columns, studs, and furring strips are assembled on the body surface, so the interior space is reduced by the thickness of the material,
In the construction method according to the present invention, the interior board can be directly fixed to the composite reinforcing material, so that it has a merit that the maximum space can be used.

According to the present invention, the work contents from the formwork work to the interior groundwork work are: formwork construction → concrete placement →
The process of scrapping off timber, shackles, panels, clearing-up → board installation → finishing process is streamlined, and material costs, transportation costs, and labor costs can be significantly reduced.
