BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a structural member and a process for producing a structural member with a working surface and a profile frame which supports the working surface.
2. Discussion of Relevant Art
Structural members, in particular, structural members for wall and ceiling shutterings, are already known, and have a shuttering skin of a wooden multilayer panel and a profile frame which is made of steel or aluminum. The profile frames made of aluminum are preferably used for a light construction. In particular, a light construction such as that provided by an aluminum profile frame, as a secondary shuttering, makes rapid work possible without a crane. Fields of use are therefore preferably the building of dwellings, small reconstruction work, and also all fields in which shuttering has to be used without a crane or outside the reach of a crane.
This known shuttering with a wooden multilayer panel entails some disadvantages. Wood is expensive and increasingly less available. Due to a phenolic resin coating and bonding on both sides, such a shuttering skin can give rise to the problem that it is not easily burned. Also, some landfills no longer accept this wood. The shuttering panels have to be nailed and/or screwed in order to connect them to the profile frame. The wood can be mechanically damaged by splintering during nailing.
SUMMARY OF THE INVENTION
Likewise, in the event of damage, a splintering of such wooden shuttering panels can occur on the building site. Moreover, the material is affected by weathering and water uptake. Additionally, a silicone seal is required for the inclusion of the shuttering panels in shuttering frames or profile frames, so that the length changes due to moisture uptake are equalized by the elastic joint. Furthermore, in mechanical cleaning of phenolic resin coated panels, a thickness of up to 440 g per square meter is scraped off, so that an increased use of parting agent is necessary. The impact resulting therefrom on the ground water is considerable.
These objects are achieved according to the invention by a structural member having a working surface, a profile frame that supports the working surface, and is arranged perpendicular to the working surface and has at least one frame member forming the profile frame. The working surface and the profile frame are formed integrally as an injection molded part. These objects also are achieved by a process for the production of the structural member according to the invention, comprising: cutting at least one beam profile and at least one transverse web to size; placing the beam profile and the transverse web arranged thereon in an injection mold; producing in one injection process a structural member having a working surface in a profile frame running on the outside of the working surface and having frame members running perpendicular to the working surface formed by beam profiles that are partially embedded in injection molded plastic. These have a working surface which is made of wood. These working surfaces have, at least on the narrow side, two hook elements with which the scaffold floorings are mounted on the scaffolds. The wooden working surface likewise has the abovementioned disadvantages.
Thermoplastic wastes increasingly arise which are not to be deposited in waste dumps but which are to be reused in the sense of the Recycling Economy Law. Also, the price of new plastic steadily becomes lower, and a supply seems to be insured for several decades, since the ability of the thermoplastic resins to be recycled is initially guaranteed.
The invention therefore has as its object to provide a structural member which makes it possible at least to save wood resources and to use plastic, which itself is recycled or at least recyclable, makes possible a further reduction of the weight of a structural member, and can nevertheless take
