Abstract: A construction element for limiting a fore part of a formwork consists of a prefabricated element having a width which corresponds to the thickness of the construction work to be erected and a modular length. The element comprises openings for being able to push through reinforcing irons, pipework or the like tubes. Because the element is foreseen to remain in the wall, it is produced preferably with a relatively fine concrete in which a reinforcing mesh of synthetic material is enclosed, which extends also over the openings and prevents the outflow of concrete at the time of pouring the latter into the formwork. Such a shuttering element allows a fast and precise limiting of the formwork in the case the construction work is not poured in one part or is needing recesses for a crane. It requires no cleaning off or pulling off wooden parts when the joining part is produced.

Abstract: A powder coating installation comprising a cabin having walls made of a non-conductive plastic material. The lower part of the cabin has a V-shaped section and terminates in a collecting channel which is connected to a suction device. The installation further comprises a cleaning device with a hollow frame, the form of which compliments the contours of the internal form of the cabin and which comprises gas outlet holes along its periphery. The frame is connected to a source of pressurized fluid, e.g., air. The cleaning device further comprises cleaning means such as sponges, cloths and the like, which may be provided on the same frame or on a separate frame. Use of a non-stick, non-conductive cabin and of the cleaning device enables the installation to be easily and quickly color converted and eliminates much of the previously wasted colored powder.

Abstract: The reinforcing rod holder includes a hollow body (1) having a depression in which the downwardly bent reinforcing rods (2) are inserted in such a manner that their U-shaped anchoring portions protrude. The free end (3 and 4) of the reinforcing rods are disposed entirely in the hollow body, together with the bend portion. To permit insertion of the anchoring portions, the hollow body is provided with apertures (5), and holes (6) having a diameter which is approximately identical to the diameter of the reinforcing rods are provided at the two ends of such apertures (5), while the central portion of the apertures is sealed by two overlapping flaps (7). The hollow body is further provided with mounting or support ribs (8) at the apertures (5) and two spacer ribs (9 and 10) between the last three apertures (5) in order to serve as support faces for the ends of the reinforcing rods. The hollow body, containing the reinforcing rods, is filled with expanded plastic material.
