Formwork for the edge formation of reinforced concrete prefabricated panels.

Description.

The invention relates to a formwork body for the edge formation of precast reinforced concrete panels. Until now, prefabricated panels were shuttered with boards on the front sides. For the formation of teeth, grooves, etc., attached plank pieces were used. This resulted in a lot of work and wood waste.

To connect the prefabricated panels to each other, there are many round steel loops that come from the front Concrete protruding is required. For this purpose, holes had to be drilled through the face formwork. At the Removal of the formwork was then inevitable, its partial destruction.

In the main features, the formation of the end faces of prefabricated panels is the same, since after Prior art appropriate arrangements of the toothing and the one making the connection with the nacabar plates Round iron loops are made largely uniform.

In many cases, the round steel loops have been omitted because, as mentioned above, they pose difficulties for the Prepare the formation of the face formwork. The connections between the panels, which are necessary for structural reasons were then through complex and expensive measures,

such as concreting a reinforced in-situ concrete layer on the ceiling slabs.

The formwork body according to the invention for the edge formation of precast panels can be used for both corner and wall panels. A uniform shape is chosen for each species. The thickness of the panels can be any, it does not affect the formation of the formwork body.

In the drawings, sheet 1 to sheet 5, examples of the design of the rigid foam formwork body are shown. The drawings on pages 1 and 2 each show a formwork body design for wall panels, the design according to page 1 being used for multiple production, while the design according to page 2 is intended for individual production.

The formwork body (1) has a uniform Clearance grooves (2) for the interlocking of the plates over the grouting concrete. At constant intervals round steel loops (3) are embedded in the rigid foam formwork. Before assembling the panels the adhesive body is removed by scraping or burning. The round steel loops overlap with those of the adjacent panels and, after being cast with in-situ concrete, create an immovable connection. When concreting the prefabricated slabs, only a stiffening element is required to hold the formwork in place Squared timber required.

On sheet 3 and sheet 4, the design of the formwork for prefabricated ceiling panels is drawn. the Arrangement of the teeth and the round steel loops is analogous to the formwork unit for the wall panels.

Sheet 3

On sheet 5, a section through a formwork body is shown, which is provided with recesses (4) and bores ( 5 ) for the subsequent insertion of the round steel loops (3). The formwork body made of rigid foam is therefore less bulky, and production is also easier.

Several formwork elements form a frame around the precast slab and thus protect it from being pushed off the edges during transport and storage.
