DE1902816A1 - Metallic formwork forms for ceiling production - Google Patents

Description

The invention relates to metallic formwork forms with Sondergeata.lt., Which are suitable, in a simple manner Dek— ken made of concrete, both reinforced and simple and also with a composite construction, for example in bricks and concrete heart crystals. At the moment, when making concrete floors, it is necessary to erect preliminary complex reinforcements Carry the appropriate, previously used formwork and hold it in place.

The aim of the invention is to produce shuttering forms which, thanks to their special shape, make it possible to achieve the above To eliminate disadvantage and thus the production of concrete ceilings without supporting reinforcements. This is practically done by means of light and monolithic formwork forms Metal plates of small thickness and the shape of an inverted ü reached, their appropriately shaped side walls against the lower puddles of Prtifil double T-beams, as usual the Fonneisträger or beams are called, which are supported against each other at the same distance in such a way

Figure 1 is a perspective view of the arrangement of the formwork forms shows for making the blanket according to the invention;

FIG. 2 shows part of the front end according to FIG. 1 and thus the frontal section through the molded article according to the Invention. ';

In the drawings ■ 1 are the formula carriers or bars, which form the structure of the ceiling under construction and with respect to arranged at the same distance from each other and so distributed "are that the sturgeon is covered by this very ceiling. The Formwork: forms 3 will be against the lower flanges 2 of these Forraisoriträger. Etbg-es-tütat *

Each formwork form 3 is made of a metal plate with the form of an inverted TJ of small thickness. The two Sidewalls 4 of the plate are slightly outward inclines and ends in end parts diverging from one another 5. These end parts 5 are furthermore provided with suitable hook-shaped curvatures 6 ″, as a result of which the shape of the loop is based on the lower flanges 2 of two adjacent 'form iron supports. The horizontal wall of the misshapen plate is Above that, stiffening ribs 8 are provided on the underside, so that deformations of this wall due to the loading of the concrete forming the ceiling section 7 are avoided will. ,

In order to separate the forms, that is to say, a simple and smooth removal of the forms after the solidification of the ceiling casting is achieved, they are unhooked from the two hook-shaped crimps 6, which form the end of the Sidewalls of every shape form _t and ssv / ar raitteis hooks 11 and two tie rods 1.2, the free ends of which are connected with a control element 15 x ^r ; which, according to the embodiment of Figure 2, consists of an angle lever with handle 14 ..: ;:

By operating the handle of the angle lever 14, the two side walls of the formwork are caused to bend elastically (this bending occurs due to the special design of these side walls) in such a way that the respective ■ curved ■■ "ends 6 are brought closer to each other -. and thereby of the flanges 2 of the FormeisenträgerV1 on which they were supported, free to come Since the width of the Horlaontälwandungen Sekalungeform off ^T is always given züglich of Zwischenachsabstandes the form of iron exchanger on which they are supported, can AEIE Scha-

With a view to brevity, the invention has been made explained only on the basis of a single embodiment. Bo is it goes without saying that instead of the form support beams Or sonatige girders in reinforced concrete or the like. Can be used if they only carry ribs at the base and Spamielamente or others can be used instead of the angle lever Facilities designed to achieve the same result are used; also can shapes of any any elastic material other than metal, which are suitable for this purpose, used within the scope of the invention will.
