DE2919468A1 - Universal formwork panels corner joint angular piece - has shanks of unequal length permitting use on inside and outside corners - Google Patents

Abstract

The constructional system uses standard-size panels with metal frames and a skin forming a sheathing for the building. The angular unit for corner connection has fittings in its shanks for attachment of form panels. One shank (1) is longer than the other (2). The panel attachment fittings in the two shanks are pref. at the same distance from the open shank end. They can be in the form of apertures (3, 4). The angle piece can be effectively used in both outside and inside corner, obviating any need for different units.

Description

Angle for corner connections

in formwork, the invention relates to an angle for corner connections for formwork with devices in the legs for connecting formwork panels.

This type of angle is used in formwork systems with formwork panels standardized sizes with metallic frame and facing formwork skin. With these Systems, it is common to create an outside corner for one to be shuttered Wall the formwork panels that meet in the outer corner with an isosceles one Connect angles to each other. These are standard steel angles, in the legs of which devices, mostly openings, are present to the two adjacent formwork panels enclosing a right angle with one another connect to. This corner formation has proven itself.

For the production of the opposite of such an outside corner Inside corner, inside corner elements are required in these systems, which in their construction adapted to the respective sytoem (DBGM 67 51 166). This element forms with its main legs the two formwork surfaces in the inside corner and has more Leg for connecting the adjacent formwork panels.

Inside corners of this type are generally used today. she are very expensive and have the disadvantage that for inside and outside corners different parts are needed.

The invention is based on the object of creating a corner bracket, for the connection of formwork panels both in the outer corner and in the inside corner can be used, so that only one and the same for both corners Element is required.

This object is achieved according to the invention in that a non-isosceles Angle is used in which one angle leg is longer than the other. Such an unequal angle is used to form the outer corner in the previously known form used, i. an adjacent formwork panel is attached to the Outside one leg of the angle connected. The part of the long angled leg, which is left free from the connected formwork panel is part of the formlining.

To form the inside corner, however, an adjacent one is connected Panel on the outside of the shorter leg, while the connection of the other adjacent formwork panel on the inside of the longer leg. In In this case, the entire outside of the long leg forms part of the Formwork skin.

With an angle of this kind, it makes sense to use the devices to Connect the formwork panels in such a way that they have the have the same distance from the free end of the legs.

A particularly simple design of this angle results when Openings are provided in the legs for connecting formwork panels. It does not matter whether these openings allow the insertion of fasteners serve, for example, are round, oblong or angular.

By using angles for corner connections according to the invention there is a considerable reduction in costs when purchasing the formwork systems, Easier to keep skimmed and also less complicated and faster suitability on the construction site, as the same component is always used for all ticks.

The invention is described on the basis of an exemplary embodiment.

Fig. 1 shows the upper end of a corner bracket in a perspective view.

Fig. 2 shows the top view of a shuttering with an inner corner and an outer corner with the help of a Yclrwinkel according to the invention he corner angle shown in Fig. 1 has a longer leg (i) and a shorter leg (2). In both thighs there are openings (3, 4). The distance a of the openings (3) in the leg (1) from the outer free end of the leg is exactly as large as the distance a the Openings (4-) from the free end of the leg (2).

Such a corner angle can be made from a normal hot-rolled steel angle consist or be folded from sheet metal.

The top view in Fig. 2 of a corner turned in shows in the outer formwork the connection of the formwork panels (5, 6) by an angle (7). In the outside corner are both adjacent formwork panels (5, 6) on the outside of the two Legs (1, 2) of the corner bracket (7) connected.

In the case of the inside corner, the formwork panel (8) is attached to the outside of the narrow leg (2) connected. The other adjacent shuttering panel (9) is, however, connected to the inside of the long leg (1).

The example shows how all formwork elements are connected to one another Bolts (10) and wedges (11) are shown. The invention is independent of whether the anchor (12) are arranged between the formwork panels or in the formwork panels. It Formwork panels can also be used instead of a wooden formlining (13) have one made of metal.
