Abstract
PURPOSE: To obtain the titled board for construction, which is light and abounds in a sound insulating property, easily by a method wherein a large number of hollow portions are formed between surface and back boards by the surface and back boards and hollow portion forming members, and an undiluted solution of synthetic resin containing a foaming agent is injected from through holes communicating with hollow portions drilled to one surface board and foamed.
CONSTITUTION: A large number of hollow portion forming members 3 in square frame shapes, parting plate shapes, cylindrical shapes or the like are disposed between a surface board 1 and a back board 2 consisting of asbestos slate, etc. at proper intervals. Through holes 7 communicating with hollow portions 6 are drilled to one surface board of the surface and back boards 1, 2 while an undiluted solution 8 of synthetic resin to which a foaming agent, etc., such as foaming epoxy or phenol resin, etc. are mixed is injected into each hollow portion 6 from the through holes 7 and foamed, thus obtaining the titled board for construction at low cost. When the boards for construction are connected and used, they can simply be connected when both side edge portions 5 are united, reinforcing rods are erected, and concrete is filled.
