초록 ▼

A method of manufacturing rigid frame building elements filled with hard foam plastic, said method comprising the use of prefabricated, rigid, dimensionally stable, hollow skeleton frames, the hollow interior spaces of said skeleton frames are foamed and filled with closed cell hard foam plastic serving as heat insulation, and the elements are subjected in a press to compression pressure which overrules the foaming pressured exerted on the frame of an element from inside. For continuous-action manufacture, the used press is a (known as such on the basis of size presses) continuous-action press machine whose lower frame is equipped with lower conveyor means (4) and upper frame with upper conveyor means (5), said conveyor means confining between themselves a conveying gap, in which the passing elements are maintained subjected to compression pressure by means of pressure members (7) carried by said conveyor means. The conveying gap, defined by said conveyor means and limited on at least one side by a horizontal tangential plane of parallel-disposed, crosswise of the machine extending rolls (5a), is set to be smaller than prefabricated skeleton frames. The prefabricated skeleton frames are fed into the conveying gap which due to the action of elements passing in said gap expands in a manner that each roll (5a) is capable of moving vertically against the force exerted by pressure members (7). Conveying speed is adjusted in view of the length of said conveying gap in a manner that expansion of a filling foam and the pressure generated thereby has substantially ceased by the time an element leaves the conveying gap.

A method of manufacturing rigid frame building elements filled with hard foam plastic wherein the building elements have wooden frames covered by plates on opposite sides forming enclosed hollow interior spaces, the method comprising the steps of: charging a quantity of delayed foaming plastic material into the enclosed hollow interior spaces of the building elements, delivering the charged building elements into a conveying and compression gap between upper and lower roller conveyors before the foaming plastic material expands to produce pressure within the interior spaces, driving the rollers of the lower conveyor to advance the building elements along a conveying path through the conveying and compression gap, engaging the plates covering the building elements with a plurality of rollers of each of the respective upper and lower roller conveyors throughout advancing of the building elements along the conveying path, said engaging with the upper and lower pluralities of rollers being at lines transverse to the conveying path and extending substantially across the width of the surfaces of the plates wherein the lines are closely spaced along the conveying path so that said engaging resists bending of the plates between the lines due to pressure of the foaming material, maintaining said engaging step in the conveying and compression gap for a duration greater than the duration required for the expansion of the foaming plastic material and the cessation of the pressure exerted thereby, compressing the rollers of the upper conveyor against its respective engaged plate during said maintaining and engaging steps by means of pressure members with a pressure exceeding the pressure generated by the foaming plastic material within the building elements, and individually moving the rollers of the upper conveyor in a vertical direction during the maintaining and compressing steps so that the rollers of the upper conveyor follow dimensional changes of the building elements between the plates and maintain substantially even pressure on the plates.
