Abstract

PURPOSE:To prevent the positional displacement of fixed parts and the damage of connecting positions generated by the collision of an undiluted solution with the injection of the undiluted solution by protecting the fixed parts and the connecting positions positioned where the undiluted solution at high speed collides on the injection of the undiluted solution by a buffer material allowing the impregnation of the undiluted solution. CONSTITUTION:A shell structure 8 is set while a back plate 2 is directed downward and a spacer 16 is held between a top force 14 and a bottom force 15 for a press for injection, an injection nozzle 17 for a high-pressure injector is connected to a filling port 12 under the state in which the whole circumference and upper and lower surfaces are constrained, an undiluted solution of urethane foam, etc. is injected into the shell structure 8 at high speed and the inside is foamed, and an integral heat-insulating layer 3 is formed, thus completing a floor heating panel (P). Since a buffer material 13 is mounted where the undiluted solution collides and a joining position and a buried nut 6 are not damaged by the collision of the undiluted solution and are not displaced even when they are positioned at said section, defectives due to these causes are hardly manufactured.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a floor heating panel in which a heat insulating layer made of urethane foam or the like is injected into the panel.

This type of underfloor heating panel described above has conventionally been constructed by injecting and filling an undiluted solution such as urethane foam into the inside of a hollow flat plate-like structure with heat medium pipes inside. It has been manufactured by forming an integral heat insulating layer, but when injecting the undiluted solution of urethane foam into the outer shell structure, there is a collision of the electric current at K speed, so the outer shell structure has a In the example, if the implanted nano 1- etc. temporarily fixed at the position where it collides with the original electric current is shifted, or if the collision A device t Kokoru junction 181 σ) A σξt & Th occurs. It was easy, and the ratio of defective products or outstanding products was 1M.

The present invention is capable of completely eliminating the problems of the conventional art, and is capable of manufacturing a towel with a single floor that hardly causes displacement of fixing parts or damage to the connecting tube. The purpose is to propose a method.

A undiluted solution of urethane foam is poured into the inside of the drawing body (8) at high speed to cause internal foaming, and the outer shell is filled with a heat medium inside (8), and a stable material is wrapped around the tube (4).
