Traditionally, ceiling materials, wall materials, and other building materials were made of wood.
It was common to have a structure in which a core material such as gypsum was used, and a surface material made of paper, iron plate, etc. was laminated together with an adhesive on one side.

However, such construction materials have a heavy specific gravity and are difficult to work with. It's bad. @It takes time to process, and has the drawbacks of lower heat insulation, higher hygroscopicity and water absorption, and inferior dimensional stability compared to synthetic resin foams. There was a disadvantage that an adhesive was required to fix the θ component. Moreover, changes in the core material created separate problems. In other words. The quality of the core material made of the above-mentioned molded body is uniform, so when a construction board to which this core material is fixed is bent into a member with an out-cornered corner, the core material at the bent portion is inferior in flexibility and elasticity. , there were problems such as the part breaking or being unable to form the desired protruding corner. In order to solve these drawbacks, the present invention has been developed by
One of the objectives is to bind the core material and the constituent parts all at once, and to solve the problems of thermal insulation, sound insulation, processability, workability, and economy.

For other purposes, the sheet-like material to be laminated on at least one side of the core material is used to construct buildings using base materials with strong mechanical strength and flexibility, such as metal foil, synthetic resin film, and 10-proof water-treated base materials. In addition, the skin layer of the core material at the contact area between the sheet material and the core material is made semi-hard or soft, so that the foam structure of the core material will not be destroyed by bending. However, 15 is also a layer with flexibility and elasticity that improves the appearance and strength of the protruding corners. An embodiment of the method for manufacturing a construction board according to the present invention will be described in detail below with reference to the drawings.

Further, it is preferable that the applicator 13 be located not far from the position where the raw material α is discharged or sprayed. That is, this is because if separated, the softening substance β will evaporate or the like before it comes into contact with the raw material α, making it difficult to obtain a soft layer of the required depth. Further, the temperature of the sheet-like material 1 is cooled by heat exchange for vaporization, etc. for the evaporation of the softening substance β, and the raw material α is

When the polyethylene sheet reaches the coating machine 13, for example, directly below the spray pot, water is sprayed onto the surface from a spray gun in the form of a mist. After that, raw material α for polyurethane foam consisting of polyol, polyisocyanate, blowing agent, etc. heated to, for example, 20° C. is discharged onto the water-dispersed surface of the polyethylene sheet while being mixed by a feeder 12, such as a mixer 12. do. A sheet-like material 1, such as aluminum foil, is layered on top of it and fed into a mold 4, where the raw material α reacts and foams and is molded to a predetermined thickness, forming a continuous sandwich structure from the exit. It is sent as body A. Therefore, two grooves B, for example, are bored at arbitrary locations on the molded body A using a V-shaped cutter (not shown) as shown in FIG. The depth h of this groove B can be arbitrarily set within the range of the thickness H of the synthetic resin foam C and H>h. In addition, the maximum layer of the surface of the synthetic resin foam C that is in contact with the sheet-like material 1 has a thickness of t (t=
Only the range H-h) has a foamed structure as shown below. That is, water was sprayed in the form of a mist onto a sheet-like material 1 made of a material that does not permeate liquids, such as moisture-proofing or waterproofing, and a polyurethane resin containing polyisocyanate was discharged onto the sheet-like material 1. The structure near the contact surface with the sheet-like material 1, which has a homogeneous foamed structure, becomes a urea bond due to the reaction between water and polyisocyanate. In other words, instead of the closed cell structure in the hard case, the thickness part of t becomes an open cell structure, making it semi-hard,
Or it has become soft. Thereby, the brittleness of the foam A is suppressed, flexibility and elasticity are actively utilized, and when forming a building board into a member as shown in FIG. The foam structure of the foam A is not destroyed and the appearance can be finished into a uniform flat or curved surface.
What has been described above is only one embodiment of the present invention, and the foam A
The softening substance β, which changes the structure of the foam, may be applied only on the sheet-like material 1 near the position where the V-shaped groove is bored, the sheet-like material 1 may be provided only on one side of the foam A, or the material may be applied in batches. Thus, construction boards can also be manufactured.

Of course, the manufacturing method is the same as above, only the mold does not move.

As described above, according to the method for manufacturing a construction board according to the present invention, the layer of the synthetic resin foam that is in contact with the sheet material is treated with a softening substance over a certain thickness during the formation of the foam. It is extremely easy to form a softened foamed structure using the reaction of raw materials, and the rest of the foamed structure is the original hard foamed structure, and has the original insulation, moisture-proofing properties, and processability. It has characteristics that allow it to be used as a construction board.

In addition, when a single-shaped groove is cut into a molded product and bent, the sheet material does not break due to deformation and back-up of the softened foam structure on the back surface of the protruding corner, and the protruding corner has a beautiful appearance. There are some characteristics that can be considered. Furthermore, there is an advantage that the thickness of the softened foamed structure can be easily set by adjusting the amount of the softening substance applied. Another feature is that the brittleness of the synthetic resin foam at the bent portions is improved by utilizing a softening substance that is originally unfavorable for raw material reaction and foaming.
