Insulating construction using reinforced concrete (RC) construction, steel reinforced concrete (SRC) construction, etc. When pouring concrete, insulation boards are installed to double as formwork, and after concrete is poured, the insulation boards are glued as the concrete hardens. Relates to concrete pouring formwork construction method using heat insulating boards.

ら合成樹脂発泡体が広く採用されている。(b) Conventional technology Insulating concrete walls, columns, and beams is widely used as an energy-saving measure for concrete buildings. Synthetic resin foams are widely used as insulation boards in reinforced concrete (RC) and steel reinforced concrete (SRC) structures due to their heat insulating properties and moisture absorption properties.

般的に行なわれている。 In construction in this case, from the viewpoint of cost or shortening the construction period, as shown in Figure 9,
A heat insulating board 42 with double-sided paper or a synthetic resin foam board is fixed by nailing to the inside of a concrete pouring form 41 that forms a concrete wall surface, and after pouring concrete 43, as it hardens, the heat insulating board or foam board is attached to the concrete. A commonly used method is to attach the mold to the mold and then remove the formwork.

し、建物の断熱性能に問題があつた。 However, in this method, the heat insulating board 42 or foam board to be bonded to the concrete is weak in strength and cannot withstand the lateral pressure during concrete pouring, so the concrete formwork 41 must be provided separately. It was hot. There is also a risk that the board or foam board may become deformed due to moisture absorption from the poured concrete or temperature changes. And formwork 4
If the nailing between the board and the formwork is insufficient, a gap will occur between the formwork, and the glue will wrap around the surface of the board, etc., resulting in damage to the joint between the board or formwork and the formwork. were filled with concrete, causing heat bridges, cold bridges, etc., and problems with the building's insulation performance.
一方これらの問題点を解決するものとして、断
熱板の表面にコンクリート打込み時の側圧に耐え

コンクリート打込み型枠の型枠を構成し、かつ断
熱板の表面に貼着した硬質面材が内装下地を兼ね
る点より、工期の短縮化としてかなり有効な効率
的施工となるものでもあつた。 This type of insulation board is quite effective in shortening the construction period because the board itself constitutes the formwork of the concrete pouring formwork, and the hard surface material attached to the surface of the insulation board also serves as the interior base. It was also a highly efficient construction.

コンクリート打設時の側圧に対し、バタ間のはら

度の硬質板を必要とした。 However, with this type of insulation board, the hard surface board also serves as the interior base, so if there is a misalignment, twist, or sagging of the insulation board joints when building the formwork, it will not be possible to directly install interior materials such as walls or paper. Therefore, highly precise construction is required. On the other hand, due to the lateral pressure during concrete pouring, it was also necessary to take into account the prevention of cracking between the slabs, which required special construction and high-strength hard plates.
更に、施工時に発生する硬質板破損の補修セパ
レータ貫通孔の補修等に多くの手間を要し、建物

で、必ずしも効率的な施工とはいえなかつた。 Furthermore, it takes a lot of time to repair damaged hard plates that occur during construction, repair separator through holes, etc., and it is difficult to select interior base plates that match the usage characteristics of the building, making construction not necessarily efficient.

As a result, we newly found that a heat insulating board that uses a hard synthetic resin foam with a strength higher than a certain strength as a heat insulating board and has a laminated structure based on a specific material on both sides of the foam can be used as a good concrete pouring formwork.

枠施工となり得ることを知見した。 In other words, an adhesive surface layer with excellent adhesion properties such as concrete or GL bond is applied to the surface or back of a hard synthetic resin foam such as hard urethane foam, phenol foam, isocyanurate foam, epoxy foam, or styrene foam, and a water-resistant liner or water-resistant It has a soft surface material adhered to a single or multilayer reinforcing layer selected from nonwoven fabrics such as kraft, metal foil, polyester film, glass nonwoven fabric, asbestos paper, and charcoal paper.
By using the insulation board constructed in this way as at least one formwork of the formwork installed oppositely in place of the conventional control panel formwork when constructing the concrete formwork, it is possible to replace the conventional control panel formwork. It has been found that formwork construction can be performed simply and with better workability, reliability, and insulation properties compared to a method consisting only of the frame and a method of connecting the formwork-cum-insulating board through the wood.

つた。(c) Problems to be solved by the invention In the bent parts of the formwork, such as the protruding corners and the inside corners of the conventional formwork construction method using a control panel, it is necessary to nail the joining pieces to the control panel and Insulation was nailed to the concrete adhesive surface of the control panel, and the pieces of wood at the intersection of the control panel formwork were nailed together. In this method, the nail head driving portion is joined by the shearing force of the panel, the shearing force of the tree, the tightening force of the fibers, etc., but it cannot necessarily be said to be efficient insulation construction. Furthermore, when the same method is applied to the heat insulating board proposed by the inventor, the same heat insulating board has a soft surface material attached to one side or the front and back sides of the heat insulating layer, but the hard side, which is the strength member of the heat insulating board, such as veneer, etc. It was impossible to join by nailing, as the material was not attached and both the soft facing material and the heat insulation layer would not work even when nailed.

The heat insulating layer of the core material is made of synthetic resin foam and generally has a specific gravity of 25 to 40 Kg/m 3 . On the other hand, the soft facing materials on the front and back surfaces are made of multilayer materials such as asbestos paper, charcoal paper, glass nonwoven fabric, waterproof liner, waterproof craft, metal foil, plastic film, etc., and can withstand the lateral pressure during concrete pouring. However, there was a problem that the nails did not have enough holding power and could not be joined by nailing in the same way as conventional veneer formwork.

なる問題点を有した。 For example, No. 10 represents the conventional outer formwork advance construction method.
The construction of the protruding corner G and the inward corner H will be explained using the wood according to the figure. As shown in FIG.
If the insulation boards 31, 33 and the wood 32a are connected by nails 34, 35, no particular problem will occur when the insulation boards 31, 33 and the wood 32a are joined by nails 34, 35. However, when nailing the insulation board 33, when the nail 35 is driven, the impact of the hammer acts on the periphery of the nail portion of the insulation board 31 via the wood 32 and the nail 34. As a result, the insulation layers 31a of the insulation boards 31 and 33 and the soft facing materials 31b on the front and back sides of the insulation boards 31 and 33 are destroyed, and the joints between the insulation boards become loose, causing misalignment between the insulation boards 31 and 33 and the wood 32, and There was a problem in that the corners of the nails and the nails 33 did not come into close contact with each other, and in severe cases, the nails 35 could not be driven.

In order to install the support 7, make it self-supporting, and adjust it, the support 37 is pushed up and down and pushed down using the height adjustment screw. However, the beam bottom 38 and wall 3
9. The corners of each insulation board between the beam bottom 38 and the beam side 40 may not have the holding power of the nail or become loose due to hammer blows, resulting in gaps at the joints or distortions between the beam bottom 38 and the beam side 40. This could easily result in unstable work.

下、躯体の変形ばらつき等の問題を生じた。 As a result, during concrete pouring, slowness may creep into the corner joints between the insulation boards or into the gaps between the insulation boards and the concrete, or the formwork may become deformed, resulting in insulation defects, as well as heat bridging and cold bridging. Problems such as a decline in insulation performance due to the rhododendron and uneven deformation of the building structure occurred.

The cross-sectional dimensions of 30 x 50 mm became larger than 50 x 50 mm, which caused problems in terms of cost.

ン材１３を介在することが必要である。 Conventional construction of the interior material 12 or interior base material made of plasterboard, etc. involves nailing the insulation material of the veneer formwork, and applying GL bond or solvent-based adhesive to the surface of the integrated insulation material after concrete is poured. The so-called dumpling method was common. However, in the conventional method of using GL Bond, the adhesive contains a large amount of water, which creates a high humidity condition on the interior base material and the back side of the interior material after construction, causing moisture to migrate to the surface through the interior base material and cause mold. It was the cause of Therefore, the drying period for applying the finishing material was quite long. On the other hand, methods using solvent-based adhesives pose problems in terms of occupational health and are not efficient. With the nailing method described above, these problems are eliminated. However, this nailing method is not suitable for the insulation board 1 after concrete pouring.
It is necessary that there is little deformation of the surface, and if surface precision cannot be expected or deformation occurs, it is necessary to use a packing material 13.
