The present invention relates to a method for constructing a formwork and heat insulating panel that can be used as an interior material while remaining on the indoor side of a concrete wall.
[0002]
[Prior art]
By leaving the formwork and heat insulating panel as an interior material on the indoor side of the building as described above, it is possible not only to save energy but also to eliminate the work of removing the inner formwork. Yes, the panel has become widespread.
First, a ground ink is put out on the floor where the panel is located on the indoor side, and a plurality of panels are aligned with each other at the base ink position while using the nail to lower the lower end of the panel. After temporarily fixing, after disposing the mold located outside the room, the panel and the mold are held at a predetermined distance by a spacing member such as a separator. After fixing with the support material and binding material which consist of, concrete is poured between a panel and a formwork, and after solidifying, a support work material, a binding material, and an outer formwork are removed.
[0003]
[Problems to be solved by the invention]
Since the panel is heavier than a form made of wood or synthetic resin, a large number of nailing points are required for one panel, and a large amount of labor is required for the temporary fixing operation. It was necessary. In addition, when temporarily fixing the panels, not only must the panel be adjacent to each other so that they are kept flush with each other, but also after the work, In some cases, the panel is not flush, and the panel has to be flushed again with a mallet or the like, which makes the above-mentioned inconspicuous and leaves room for improvement.
[0004]
In view of the above-described situation, the present invention intends to solve the problem that the temporary fixing operation of the panel can be easily and quickly performed while the adjacent panels are kept flush with each other. The point is to provide a method.
[0005]
[Means for Solving the Problems]
  In order to solve the above-mentioned problems, the present invention is arranged on the indoor side of the concrete wall structure, and concrete is placed between other molds arranged at intervals on the outdoor side to cure and cure. A method for constructing a discarded formwork combined panel to be left on the indoor side of a concrete wall later, and a posture holding member for holding the panel in a predetermined posture by fitting with the lower end of the panel on the indoor side floor surfaceAs a horizontal portion that receives the lower surface of the panel and a pair of vertically sandwiching portions that sandwich both sides in the thickness direction of the panel, and on the inner surface of the connecting corner between the vertically sandwiching portion on the indoor side and the horizontal portion, Posture-holding member comprising a substantially U-shaped erection rail formed with an incisionThe plurality of panels are arranged almost flush with the indoor side of the concrete wall structure by fitting and holding the lower ends of the plurality of panels to the posture holding member, and separators and the like are arranged on the outdoor side. Another formwork is arranged at a predetermined distance from the panel by a spacing member, and these formwork and heat insulation panels and other formwork are fixed by supporting materials and binding materials made of vertical piers, square steel pipes, etc. Then, concrete is placed between the formwork material combined heat insulating panel and another formwork, and after curing and curing, the support material, the binding material, and the other formwork are removed, and the formwork material It is characterized by using a combined heat insulating panel as an interior material.
  When constructing a heat insulating panel that also serves as a formwork material, first, a posture holding member is fixed to a construction position by using a nail or the like. The fixed posture holding member is fitted and held at the lower end of the formwork and heat insulating panel. Subsequently, as described above, the lower ends of the other formwork / heat insulating panels can be sequentially fitted and held in the posture holding member to temporarily fix the adjacent formwork / heat insulation panels flush with each other. . In some cases, the rear surface of the panel may be tightly bound to a reinforcing bar using a soft steel wire in order to more securely and temporarily fix the formwork and heat insulating panel fitted and held by the posture holding member. Good. After the temporary fixing of the mold material and heat insulating panel is completed, as described above, another mold frame is arranged at a predetermined interval from the panel by a spacing holding member such as a separator on the outdoor side. After fixing the thermal insulation panel for materials and other molds with support materials and binding materials made of vertical piers, square steel pipes, etc., concrete is placed between the thermal insulation panel for both molds and other molds. After the curing and curing, the support material, the binding material, and the other formwork are removed, and the construction of the formwork material combined heat insulating panel is completed.
[0006]
  Also,The posture holding member is composed of a substantially U-shaped built-in rail provided with a horizontal portion that receives the lower surface of the panel and a pair of vertically holding portions that hold both sides in the thickness direction of the panel.BecauseSuitable for mass production.In addition, since the cut along the panel attachment direction is formed on the inner surface of the connecting corner portion between the vertical holding portion and the horizontal portion on the indoor side, the vertical length along the cut after completion of the construction of the heat insulating panel for formwork material. The orientation holding part can be separated from the horizontal part.
[0007]
By configuring the height of the vertical holding portion on the indoor side of the pair of vertical holding portions constituting the erection rail to be lower than the height of the vertical holding portion on the outdoor side, Since the protruding portion protruding upward can be reduced, the interior is not greatly hindered without removing the protruding portion.
[0009]
  A horizontal portion that receives the upper surface of the panel and a pair of vertically sandwiching portions that sandwich both sides in the thickness direction of the panel,Fits to the top edge of the panelBeforeIt is configured to be long enough to extend over the top edges of adjacent panels.An upper built-in rail is provided.,This topBy fitting the built-in rails across the upper ends of the adjacent panels, the adjacent panels can hardly be displaced from each other in the surface direction.
[0010]
The panel includes at least an inorganic plate and an organic plate positioned at both ends in the thickness direction of the concrete wall, and between the two plates, a foamable synthetic resin is filled between the two plates and foam-cured, whereby the two plates are sandwiched. A heat-insulating layer that is fixed and integrated is formed.
[0011]
Of the two plates, the plate located on the indoor side is an inorganic plate of a quasi-incombustible or quasi-incombustible board, and the plate located on the outdoor side is composed of a medium-quality fiberboard, thereby making concrete a panel and a mold. Without causing deformation such as waves struck by the inorganic plate due to the side pressure generated when placing between the frame, making it unnecessary to perform processing such as flattening the wall of the inorganic plate after placing concrete, Cosmetic materials such as wallpaper and cloth can be directly attached to the wall surface of the inorganic board. As the inorganic board, there are wood wool cement board, gypsum board, etc., and as non-combustible board, there are concrete, brick, tile, asbestos slate, steel, aluminum, glass, mortar, plaster, etc. The quasi-incombustible or non-combustible board does not cause a deformation such as a wave due to the side pressure generated when the concrete is placed between the panel and the formwork.
[0012]
An insertion part that can be inserted from the indoor side or the concrete structure side that is scheduled to be placed between opposing end faces of panels adjacent in the panel mounting direction, and the indoor side surface of each of the panels when the insertion of the insertion part is completed Alternatively, there is provided a step preventing member comprising a contact portion that contacts the concrete structure side surface and prevents the panels from moving to the indoor side due to the concrete pressure at the time of placing the concrete.
Just by inserting the step prevention member between the opposing end faces of the adjacent panels as described above, the contact of the step prevention member can be ensured that part of both panels protrudes into the room due to the concrete pressure during concrete placement. By preventing contact at the part, it is possible to prevent the indoor side surfaces of both panels from becoming uneven. If the step prevention member is inserted between the opposing end surfaces of the adjacent panels in the panel mounting direction from the side of the concrete structure to be placed, it is not necessary to remove the step prevention member after placing the concrete. Instead, it can function as a water stop member that can prevent the moisture of the concrete from entering the gap between the opposing end surfaces of the panels. If the water stop tape is provided in the contact portion, there is an advantage that the water stop effect can be further enhanced.
[0013]
The step prevention member is integrated with the insertion portion formed in a flat plate shape having substantially the same size as the vertical dimension of the panel, and extended from one end of the insertion portion in a direction perpendicular to the insertion direction. It is formed in a substantially T shape in a plan view including the contact portion formed in a flat plate shape that is substantially the same as the vertical dimension of the insertion portion that is in surface contact with the indoor side surfaces of the adjacent panels.

DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows a state in which a plurality of substantially rectangular formwork and thermal insulation panels 1 (hereinafter referred to as panels) for use as interior materials on the indoor side are temporarily fixed in a single plane. 1 has a three-layer structure including two inorganic plates 2 and 3 and a heat insulating layer 4 made of hard urethane or the like positioned between the inorganic plates 2 and 3. Alternatively, it may be composed of five or more layers.
[0015]
The size of the panel 1 is, for example, a long side and a short side of 1820 mm × 910 mm (this 910 mm is a width dimension on the left and right sides of the inorganic plates 2 and 3) and a thickness of 42.2 mm. The thickness of the one inorganic plate 2 is 2.7 mm, the thickness of the other inorganic plate 3 is 9.5 mm, and the thickness of the heat insulating layer 4 is 30 mm. However, the present invention is limited to the above dimensions. Is not to be done.
[0016]
As the inorganic boards 2 and 3, a veneer board, a hard paperboard, a hard synthetic resin board, a gypsum board, a rock wool board, an asbestos slate board, an asbestos cement calcium silicate board, etc. can be used. As the inorganic board 2 on the concrete wall 5 side shown in a) and (b), by using a lightweight board such as the veneer board, hard paperboard, and hard synthetic resin board, the increase in the weight of the entire panel 1 is suppressed. To be able to. Then, the concrete side surface 2A (see FIG. 3) of the inorganic board 2 made of the veneer board or hard paperboard is covered with an embossed film (not shown) having an uneven surface portion, thereby curing the concrete. While the embossed film can suppress the moisture that comes out before being hardened from being penetrated into the inorganic plate 2, the surface area of the film may increase the contact area with the concrete. In addition, it can suppress that the water | moisture content by which concrete is cured and hardened by sticking the said film on the surface 2A of the said inorganic board 2 permeates into the inorganic board 2, but the outer peripheral surface 2B of the inorganic board 2 (refer FIG. 3). ), The moisture that is produced until the concrete is cured and hardened may be more reliably prevented from penetrating into the inorganic plate 2. Adhesion can be enhanced by corona discharge treatment of the film surface to be applied to the inorganic plate 2. Moreover, you may make it improve adhesion | attachment performance with concrete by sticking charcoal cal paper etc. on the concrete side surface of the said veneer board and a hard paperboard. The carbonized carbon paper is a mixed paper made of calcium carbonate / pulp / glass (inorganic paper made by mixing a fibrous material mainly composed of cellulose pulp and inorganic powder such as calcium carbonate). You may implement the inorganic board 2 located in the said outdoor side using MDF (medium fiber board) which is an organic board.
[0017]
Moreover, the inorganic board 3 located in the indoor side uses the said gypsum board, rock wool board, asbestos slate board, asbestos cement, a calcium silicate board etc. which are a semi-incombustible material or a nonflammable material, and the said concrete wall 5 side. In addition to improving the strength of the panel 1 as a whole, it is possible not only to increase the strength of the panel 1 but also to apply wallpaper or cloth as a cosmetic finish on the flat surface of the inorganic board 3 having the above-described structure. Alternatively, the surface 3A (see FIG. 3) of the inorganic plate 3 can be directly painted. The quasi-incombustible material may be a composite plate in which a foam layer as a core material layer, a synthetic resin layer, or the like is interposed between two refractory materials such as gypsum board in addition to the above-described materials. Further, by sticking a straight film (not shown) to the surface 3A of the inorganic plate 3, moisture or the like entering from the gaps between the arranged panels 1 can be absorbed by the surface film. Not only can it be blocked, but it can also be easily wiped off the surface of the film. In addition to the surface 3A of the inorganic plate 3, not only the outer peripheral surface 3B of the inorganic plate 3 (see FIG. 3) but also the film extending to the outer peripheral surface of the heat insulating layer 4 completely penetrates the water into the inorganic plate 3 It may be possible to prevent it. Adhesion can be enhanced by corona discharge treatment of the film surface (surface 3A) to be applied to the inorganic plate 3 in the same manner as described above.

There is an advantage that can be further increased. In the case where the waterproofing tape 15 is fixed to the contact portion 14B with an adhesive, the waterproofing tape 15 is configured by providing an adhesive layer on one side of the waterproofing tape 15 in advance, or the adhesive is used as the waterproofing tape 15. Or it will apply | coat directly to the contact part 14B. Further, the dimension of the contact portion 14B of the step preventing member 14 in the panel mounting direction can be made larger than that in FIG. 8 to increase the contact area with the panel 1, and the panel is further stepped. Not only can this be prevented, but there is an advantage that the water stop effect can be further enhanced. The dimension in the insertion direction of the insertion portion 14A of the step prevention member 14 may be any dimension as long as it does not protrude from the indoor surface of the panel 1 in the inserted state. As described above, the interior corners are filled with a filler such as putty so that the chamfered recesses do not occur between the two end portions of the panels 1 and 1 and the surfaces are flush with each other. The step prevention member 14 may be made of various synthetic resins such as flame retardant polyethylene, ABS resin, and vinyl chloride, or may be other materials such as metal.

In addition, it is possible to provide a method for constructing a heat insulating panel that also serves as a mold material and can perform a temporary fixing operation more easily and quickly than a conventional method of temporarily fixing a plurality of panels while positioning them. Moreover, the panel can be temporarily fixed more stably only by fastening the back surface of the heat insulating panel for both the formwork material and fitted and held by the posture holding member to the reinforcing bar using a soft steel wire. .Furthermore, the posture holding member is composed of a simple shape having a horizontal portion that receives the lower surface of the panel and a pair of vertical holding portions that hold both sides in the thickness direction of the panel, that is, a substantially U-shaped built-in rail. Therefore, not only is the manufacturing cost advantageous, but the panel can be fitted to the erection rail without any improvement, and the degree of freedom in designing the panel can be increased. Moreover, since the cut along the panel attachment direction is formed on the inner surface of the connecting corner portion between the vertical holding portion and the horizontal portion on the indoor side, the vertical direction along the cut after completion of the construction of the heat insulating panel for both the formwork material Since the clamping part can be separated from the horizontal part, the indoor surface of the panel can be flattened over the entire upper and lower regions.
[0026]
  Claim2According to the invention, the height of the vertical holding portion on the indoor side of the pair of vertical holding portions constituting the erection rail is configured to be lower than the height of the vertical holding portion on the outdoor side. Therefore, it is possible to reduce the protruding portion protruding upward on the indoor side, so even if the protruding portion is not removed, the interior is not greatly hindered, and there is no removal work of the vertical holding portion, The work can be simplified.
[0028]
  Claim3According to the invention ofA horizontal portion that receives the upper surface of the panel and a pair of vertically sandwiching portions that sandwich both sides in the thickness direction of the panel,Fits to the top edge of the attached panel,BothIt is configured to be long enough to extend over the top edges of adjacent panels.An upper built-in rail is provided.,This topBy fitting the built-in rails across the upper ends of adjacent panels, the adjacent panels can be made difficult to be displaced from each other in the surface direction, which is advantageous in terms of construction.
[0029]
  Claim4According to the invention, the plate located on the indoor side of the two plates is an inorganic plate of the quasi-incombustible or quasi-incombustible board, and the plate located on the outdoor side is constituted by a medium fiberboard, The surface of the inorganic plate is not deformed by the side pressure generated when the concrete is placed between the panel and the formwork, and the surface of the inorganic plate is flattened after the concrete is placed. This eliminates the need to apply a decorative material such as wallpaper or cloth directly to the wall surface of the inorganic board, thereby shortening the construction period by simplifying the construction work process.
[0030]
  Claim5According to the invention of the step prevention member, it is possible to prevent a part of both panels from protruding into the room due to the concrete pressure at the time of placing the concrete, simply by inserting the step prevention member between the opposing end surfaces of the adjacent panels. By preventing contact at the contact part, it is possible to prevent the indoor side surfaces of both panels from becoming uneven, and there is no need for finishing processing to make the surfaces of the uneven panels flush. This is advantageous in terms of construction. If you insert the prevention member from the side of the concrete structure where you plan to place the panel between the opposing end faces of the adjacent panels, you will not need to remove the prevention member after placing the concrete. In addition to being more advantageous in terms of surface, there is an advantage that it can function as a water stop member that can prevent the moisture of the concrete from entering the gap between the opposing end surfaces of the panels. If the water stop tape is provided in the contact portion, there is an advantage that the water stop effect can be further enhanced. As the concrete pressure is received by the unevenness prevention member, the panel surface can be corrected to be in a flush state.
[0031]
  Claim6According to the invention, the step prevention member is integrated with the insertion portion formed in a flat plate shape having substantially the same size as the vertical dimension of the panel, and extended from one end of the insertion portion in a direction perpendicular to the insertion direction. The panel is formed in a substantially T shape in a plan view composed of a contact portion formed in a flat plate shape that is substantially the same as the vertical dimension of the insertion portion that is in surface contact with the indoor surface of both adjacent panels. It is possible to reliably prevent the panel from being stepped at any position in the front-rear direction of the panel by allowing the abutting portion to abut over the entire vertical direction of the indoor side surface or the concrete structure side surface of the panel. There are advantages.
