Abstract

Structural panel used in mfr. of corrosion-resistant pipes, containers, casings and similar articles for application in the chemical industry, is made of weldable thermoplastics. It comprises 2 relatively thin plates with interposed flat reinforcement that has numerous perforations through which both (outer) plates are welded together. The reinforcement consits of a perforated metal sheet, 'expanded metal' or a wire netting, and protrudes beyond the edges of the outer plates.

Description

Bauplatte aus thermoplastischem schweißbaren KunststoffConstruction panel made of thermoplastic weldable plastic

Die Erfindung bezieht sich auf eine Bauplatte gemäß dem Oberbegriff des Anspruches 1.The invention relates to a building panel according to the preamble of claim 1.

Korrosionsbeständige Be- und Entlüftungsrohre sowie Absaugrohre mit rechteckigem Querschnitt, Behälter, Gehäuse und dergleichen für die chemische Industrie werden vielfach aus Bauplatten aus schweißbarem thermoplastischen Kunststoff, z. B. Polyvinylchlorid, Polyäthylen, Polypropylen, hergestellt. Dabei werden die Bauplatten zugeschnitten, falls erforderlich, gebogen und durch Schweißung miteinander verbunden.Corrosion-resistant ventilation pipes and suction pipes with rectangular cross-section, containers, housings and the like for the chemical industry are often made of construction panels made of weldable thermoplastic, z. B. polyvinyl chloride, polyethylene, polypropylene manufactured. This is where the building boards cut to size, if necessary, bent and joined together by welding.

In Abhängigkeit von der Größe der Rohre, Behälter und Gehäuse müssen die Bauplatten zur Erzielung einer ausreichenden Festigkeit nicht nur eine dicke Wandstärke haben, was erhebliche Materialkosten mit sich bringt, sondern es ist vielfach auch erforderlich, besondere Verstärkungsrippen anzuschweißen. Das Anschweißen von Verstärkungsrippen ist mit einem zusätzlichen Zeit- und Materialaufwand verbunden.Depending on the size of the pipes, containers and housings you need the building boards to achieve sufficient strength not just a thick one Have wall thickness, which entails considerable material costs, but it is in many cases it is also necessary to weld on special reinforcing ribs. The welding of reinforcing ribs is associated with an additional expenditure of time and material.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Bauplatte zur Herstellung von korrosionsbeständigen Rohren, Behältern, Gehäusen und dergl. für die chemische Industrie zu schaffen, die unter gleichzeitiger Erhöhung der Festigkeit eine nicht unbeachtliche Materialersparnis mit sich bringt und bei der es nicht mehr erforderlich ist, an großen Flächen Verstärkungsrippen anzuschweißen.The invention is therefore based on the object to provide a building board Manufacture of corrosion-resistant pipes, containers, housings and the like. For the chemical industry to create that while increasing the strength brings with it a not inconsiderable material saving and which it does not more it is necessary to weld reinforcing ribs on large areas.

Zur Lösung dieser Aufgaben wird gemäß der Erfindung vorgeschlagen, daß die Bauplatte aus zwei dünnen, durch eine flächige Armierung voneinander getrennten Platten aus schweißbarem thermoplastischen Kunststoff besteht, daß die Armierung eine Vielzahl von Durchtrittsöffnungen aufweist und daß die beiden Kunststoffplatten über die Durchtrittsöffnungen miteinander verschweßt sind.To solve these problems, it is proposed according to the invention, that the building board consists of two thin, separated from each other by a flat reinforcement Sheets made of weldable thermoplastic material that reinforcement has a plurality of passage openings and that the two plastic plates are welded to one another via the passage openings.

Durch diese Ausbildung der Bauplatte kann die Wandstärke der Kunststoffplatten verringert und damit eine erhebliche Materialersparnis erzielt werden. Bei großen Flächen ist es darüber hinaus nicht mehr erforderlich, Verstärkungsrippen anzuschweißen. Der damit bisher verbundene Zeit- und Materialaufwand kann somit entfallen.This design of the building board can reduce the wall thickness of the plastic sheets reduced and thus a considerable saving of material can be achieved. With big ones In addition, it is no longer necessary to weld reinforcing ribs to surfaces. The previously associated time and material expenditure can thus be omitted.

Die Erfindung wird nachfolgend anhand eines in einer Zeichnung dargestellten Ausführungsbeispieles näher erläutert. In dieser Zeichnung ist eine Bauplatte 1 gezeigt, die zur Bildung eines nicht gezeigten Gehäuses dient. Diese Bauplatte 1 besteht aus einer Armierung 2, die in diesem Ausführungsbeispiel aus einem an sich bekanntes Lochblech gebildet ist. Auf beiden Seiten der Armierung 2 ist jeweils eine Platte 3, 4 aus schweißbarem thermoplastischem Kunststoff vorgesehen, die in ihrer Fläche geringfügig kleiner als die Armierung ausgebildet sind, so daß an der Armierung 2 ein beidseitig freier Randstreifen 5 verbleibt.The invention is illustrated below with reference to a drawing Embodiment explained in more detail. In this drawing there is a building board 1 shown, which serves to form a housing, not shown. This building board 1 consists of a reinforcement 2, which in this embodiment consists of a per se known perforated plate is formed. On both sides of the reinforcement 2 is respectively a plate 3, 4 made of weldable thermoplastic material is provided, which in their area are slightly smaller than the reinforcement, so that on the Reinforcement 2 an edge strip 5 free on both sides remains.

Die beiden Kunststoffplatten 3, 4 sind durch die Löcher 6 der Armierung f bzw. des Lochbleches miteinander verschweißt. Dies erfolgt in der Weise, daß die beiden Kunststoffplatten 3, 4 mit der Armierung in eine nicht gezeigte Form eingelegt, auf die Erweichungstemperatur des Kunststoffes erwärmt und zusammengepreßt werden. Durch die Löcher 6 der Armierung findet dabei eine Verschweißung der beiden Platten 3, 4 statt. Zur Erwärmung der beiden Kunststoffplatten 3, 4 ist es möglich, die Form und/oder die Armierung 2, beispielsweise elektrisch, zu beheizen.The two plastic plates 3, 4 are through the holes 6 of the reinforcement f or the perforated plate welded together. This is done in such a way that the two plastic plates 3, 4 with the reinforcement inserted into a mold, not shown, heated to the softening temperature of the plastic and pressed together. The two plates are welded through the holes 6 in the reinforcement 3, 4 instead. To heat the two plastic plates 3, 4, it is possible to use the Form and / or the reinforcement 2, for example electrically, to be heated.

Die so hergestellte Bauplatte 1 kann gekantet und gebogen werden, ohne daß sich die Kunststoffplatten 3, 4 von der Armierung 2 lösen.The building board 1 produced in this way can be folded and bent, without the plastic plates 3, 4 becoming detached from the reinforcement 2.

Wie in Fig. 2 gezeigt, können die beiden sich gegenüberLiegenden Kanten einer Bauplatte 1 bzw. zwei Bauplatten 1 miteinander verbunden werden.As shown in Figure 2, the two opposing edges a building board 1 or two building boards 1 are connected to one another.

Dazu werden zuerst die béiden Armierungen 2 bzw. Armierungskanten durch Elektroschweißung miteinander verbunden. Der freie Randstreifen 5 der Armierungen 2 stellt dabei sicher, daß die Kunststoffplatten 3, 4 nicht zu stark erwärmt und somit nicht beschädigt werden. Anschließend wird der freie Raum über den Randstreifen 5 und zwischen den Platten 3, 3 bzw. 4, 4 mit Kunststoff zugeschweißt.To do this, the two reinforcements 2 or reinforcement edges are first placed connected to each other by electric welding. The free edge strip 5 of the reinforcements 2 ensures that the plastic plates 3, 4 are not heated too much and thus not be damaged. Then the free space is over the edge strip 5 and between the plates 3, 3 or 4, 4 welded with plastic.
