Description

Schalelement and slab formwork with such

Schalefement

The invention relates to a formwork element with a frame and a formwork skin according to the preamble of claim 1. The invention further relates to a slab formwork with such a formwork element.

It is known, Schalelemente for the production of concrete floors

use. In particular frame panel formwork elements are used, which at least partially form a mold for filling of liquid concrete. After hardening of the concrete, the formwork elements are removed.

The formwork elements have a frame and a formwork skin. When handling the formwork elements on a construction site, it may

Damage to the formwork elements come. Particularly endangered are the corners of the formwork elements that are exposed during transport and storage and when falling particularly large forces. Typically, therefore, attempts are made to form the corners of the formwork elements particularly hard and resistant.

Object of the present invention is in contrast to provide a sustainable scarf element and a slab formwork with such a formwork element, in which the formwork element is cost-effectively produced and easily repaired in case of damage.

This object is achieved by a formwork element with the features of claim 1 and by a slab formwork with the features of claim 12. The dependent claims indicate expedient developments.

The object of the invention is thus achieved by a formwork element with a frame and a formwork, wherein the formwork element has a first Eckaufsatz, which is placed on a first corner of the frame, wherein the first Eckaufsatz is formed predominantly of plastic and wherein the frame two in the first corner has directly connected struts.

According to the invention, it is thus intended to disguise a first corner of the frame with a first corner attachment. The first corner essay is predominantly made of plastic. The first corner essay serves as a "sacrificial panel", which receives small bumps and scratches on the formwork element, without causing damage to the supporting frame.

The corner essay can be made entirely of plastic. The corner essay may be formed of plastic, wherein the plastic may contain reinforcing admixtures. For example, the Plastic glass and / or carbon fibers or balls or the like buried.

For secure attachment of the first Eckaufsatzes the first corner essay is preferably positively connected to the frame. The installation of the first Eckaufsatzes is facilitated when the first Eckaufsatz is connected via a first latching connection with the frame.

More preferably, the first corner essay by a first

Adhesive connection connected to the frame.

The first corner attachment can be connected to the frame by a first screw connection and / or a first riveted connection.

In a further preferred embodiment of the invention, the frame made of metal, in particular aluminum, is formed. The at least two in the first corner interconnected struts of the frame may be connected by a welded joint. Preferably, the two struts are connected by exactly one welded joint.

The struts are preferably formed in the form of extruded profiles.

Longitudinal struts of the frame are preferably made more massive than crossbars of the frame to the load capacity of the frame

maximize weight.

The two struts can mitred one another and

be welded together. In a particularly preferred embodiment of the invention, the struts in the first corner are partially recessed. The first corner is preferably welded indoors. Outside

on the other hand, where a weld would be very costly, the gap creates a gap that is closed by the first corner attachment. Also, the corner essay of the concrete-tight covering of the first corner, if abutting struts of the frame is not complete

be welded together.

Preferably, the first corner cap hides the recess.

More preferably, the formwork element in the frame main plane is formed rectangular parallel to the Schalhautebene, wherein the first corner is located in the frame main plane. For the purposes of the present invention, the frame main plane is understood to mean a plane which runs parallel to the plane

Formwork skin or runs parallel to the formwork skin of the formwork element. The frame main plane runs in the middle of the depth of the

Frame, which is determined perpendicular to the formwork or formlining.

The longitudinal axis of the first corner preferably runs perpendicular to the main skin plane or perpendicular to the frame main plane. In other words, the first corner connects two longitudinal sides of the formwork element, which in the construction of a slab formwork on further longitudinal sides another

Shutter elements abuts.

The first corner attachment may at least partially cover the frame at one side parallel to the frame main plane. Particularly preferably, the first corner essay sums the frame on both corner sides parallel to

Frame main level at least partially. The frame and at least one corner attachment, in particular the frame and all corner attachments, can together form planar abutment surfaces to the same adjacent formwork elements.

The formwork element may have a second corner attachment, which is placed on a second corner of the frame, wherein the second corner attachment is formed predominantly of plastic. The second corner essay can analogously to the first corner essay have all the features of the first Eckaufsatzes described above. In particular, the second corner can lie in the frame main plane. The second corner essay thus also covers two longitudinal sides of the shell element, which in the construction of the

Scarf element can rest on other long sides of other formwork elements.

In a particularly preferred embodiment of the invention, all corners, in particular four corners, of the formwork element in the frame main plane are each clad by a corner attachment described above. As a result, all claimed by special loads corners of the formwork element are protected by appropriate Eckaufsätze and are easier to produce.

The first Eckaufsatz or all other Eckaufsätze go preferably just in longitudinal sides of the frame. In other words, the first Eckaufsatz forms with two longitudinal sides of the frame each have a flat surface. Likewise, the other corner essays with respective longitudinal sides of the frame can form flat surfaces. This allows several

Shutter elements are placed together without gaps. The leakage of liquid between a plurality of juxtaposed shell elements can thereby be effectively avoided. The frame may be coated, in particular powder-coated, to reduce the adhesion of concrete to the formwork element. The frame can be coated with all corner inserts arranged thereon, in particular powder-coated. The frame thus forms, together with the first corner attachment or together with all corner attachments arranged on the frame, homogeneously coated outer surfaces. Alternatively, the

Frame without corner caps coated, in particular powder-coated, so that the corner attachments are easily replaceable.

The formwork element is preferably rectangular in shape and has a corner attachment on the frame at all four corners of this rectangle.

The formwork element may have connection projections to the

To be able to connect the formwork element with a column head of the slab formwork.

The connecting projections may be formed on an angle plate. Alternatively or additionally, connecting projections may be formed on a metal strip. The frame can thereby

Manufacturing technology particularly easily extruded sections are produced without the connecting projections from the

Extruded profiles must be milled out.

The object of the invention is further achieved by a slab formwork with a previously described formwork element.
