[0012]
As will be described later, the paper plates 4 and 5 are necessary in the process of forming the heat insulation panel 1 laminated with the corrugated thin plate 2, but can be used as a laminated plate of the heat insulation and formwork building material A. is there.
[0013]
As an example of the heat insulation panel 1 made of hard polyurethane, an isocyanate and a polyol manufactured by Huntsman Japan Co. are mixed and foamed and molded in an environment of 55 ° C. At this time, the mixing ratio of isocyanate and polyol is 62:38 wt /%.
[0014]
Further, the corrugated thin plate 2 is formed in a rectangular shape having the same size as the heat insulating panel 1 by an iron thin plate having a thickness of 0.1 to 0.5 mm, and the corrugated cross section, that is, the mountain streak 2m and the trough 2v are in the vertical direction. It is bent into a waveform so as to be oriented, and is configured to obtain high rigidity against a load in the vertical direction. The higher the corrugated height of the corrugated thin plate 2 is, the higher the rigidity is. However, in order to use it as a heat insulating material, the height of the corrugated plate is desirably 5 to 15 mm.
[0015]
As an example of the corrugated thin plate 2, an iron thin plate manufactured by Shinnaka Steel Co., Ltd. processed to have a plate thickness of 0.25 mm, a corrugated pitch of 31.8 mm, and a corrugated height of 9.0 mm is used.
[0016]
Next, the manufacturing method of the heat insulation panel 1 laminated with the corrugated thin plate 2 will be described with reference to FIG. 7. The polyurethane machine 20 is supplied with isocyanate and polyol from an isocyanate tank 21 and a polyol tank 22, respectively.

At this time, the corrugated thin plate 2 may be placed on the distributed liquid mixture.
[0018]
While the mixed liquid is conveyed together with the corrugated thin plate 2 by the upper and lower belt conveyors 25 and 26, an unfoamed polyurethane material made of the mixed liquid is foamed in the molding space S maintained at a predetermined temperature. Thereby, the rigid polyurethane foam, that is, the heat insulating panel 1 is formed, and at the same time, the corrugated thin plate 2 is laminated on one surface thereof. At the time of foaming, the upper paper 4 and the lower paper 5 are integrally laminated on the upper and lower surfaces of the heat insulating panel 1 on which the corrugated thin board 2 is laminated, and a gap formed between the corrugated thin board 2 and the lower paper 5. A portion of the foamed polyurethane foam is loaded. The heat insulation panel 1 on which the corrugated thin plate 2 is laminated is cut to a predetermined size and carried out by another belt conveyor 29.

Thus, the plurality of mounting holes 6 of the horizontal portion 3H communicate with the upper end surface of the heat insulating panel 1.
[0022]
Next, with reference to FIGS. 4-6, the case where the building form F is constructed | assembled using the said heat insulation and formwork building material A which consists of the heat insulation panel 1, the corrugated thin board 2, and the bar member 3 is demonstrated.
[0023]
As shown in FIG. 4, there is a concrete placement space 8 on the foundation B, and a plurality of lowermost thermal insulation and formwork building materials A (subscript d is added to A) on both sides thereof, The corrugated thin plate 2 is built in a row and connected to the opposite side of the concrete placement space 8, and then a plurality of assemblies are installed on the upper end surfaces of the heat insulation and formwork building materials Ad, Ad on the outermost and lowermost layers thereof. The both ends of the ties 10 are inserted through the mounting holes 6, and the inner and outer bottom-stage inner and outer heat-insulating / framework materials Ad, Ad are joined together, and then the lower-most inner and outer heat-insulating On the upper end surface of the formwork building material Ad, the lower end surface of the heat insulation and formwork building material Am (A is denoted by m) in the middle stage is connected to the lower end of the heat insulation and formwork building material A. Built in the same direction, and in the middle stage, the outer heat insulation and formwork building materials Am, Am on the upper end surface of Am The assembly ties 10 are inserted through the mounting holes 6 and the intermediate heat insulation and mold frame building materials Am and Am are joined together, and in the same manner, the other intermediate heat insulation and mold frames are connected. The building material Am and the outermost heat insulation / framework building material Au (A is denoted by u) are sequentially built in the upper end surface of the outer middle heat insulation / framework building material Am inside the lower part, These upper end surfaces are connected by a plurality of the assembly ties 10.
[0024]
As shown in FIGS. 5 and 6, the assembly tie 10 is formed by welding a reinforcing material 10b to a main body 10a formed by bending round steel into a bite shape, and as shown in FIG. The bent end portion of the reinforcing material 10a collides with the inner surface of the heat insulating panel 1 to prevent the heat insulating material 1 from falling.
[0025]
As shown in FIG. 4, a mold F composed of inner and outer mold walls WI and WO is assembled. At this time, each heat insulation and formwork building material A constituting the formwork walls WI and WO is very lightweight, and can be coupled to the heat insulation and formwork building material A by inserting the assembly tie 10, Since the conventional support work such as thick ends is unnecessary, the construction work of the mold F can be performed quickly, easily and at low cost.
[0026]
Further, after the mold F is completed, concrete is placed in the concrete placing space 8 between the inner and outer mold walls WI and WO. At this time, each heat insulation and formwork building material A constituting the formwork walls WI and WO has a mountain line 2m and a valley line 2v up and down on one side of the heat insulation panel 1 made of hard polyurethane (on the side opposite to the concrete placement space). Since the corrugated thin plate 2 oriented in the direction is laminated, the rigidity in the vertical direction is high, and it is not deformed or damaged even when subjected to the concrete placing pressure.
[0027]
In this case, since the heat insulation panel 1 made of hard polyurethane does not need to have load resistance itself, the hard polyurethane has a low density comparable to that of a heat insulating material not intended for use in a formwork. It's okay.
[0028]
Next, with reference to FIGS, will be described actual施例of the present invention.
[0029]
FIG. 8 is a partially broken perspective view of a heat-insulating / framework building material, and FIG. 9 is a cross-sectional view taken along line 9-9 in FIG. 8. The same elements as those in the reference example are denoted by the same reference numerals.
[0030]
The actual施例is of the form F, among the outer mold wall WI, is obtained by allowing a curved construction of WO, the insulating panel 1 constituting the heat-insulating and formwork construction material A has, in its lateral width direction A plurality of slits 40 are inserted in parallel in the vertical direction, that is, in the direction of the ridges 2m and valleys 2v of the corrugated thin plate 2 at equal intervals, and the flat portion 3H of the bar member 3 is also parallel to the slits 40. Insert another slit 41. Thereby, the heat insulation and formwork building material A can construct the outside formwork walls WI and WO inside the corrugated thin plate 2 in the corrugated direction, that is, curved in an arc shape in plan view. By placing concrete in the installation space 8, it is possible to construct a curved housing wall that is curved in an arc shape in plan view.
