Description

Hummel, Heinz, Müschener Str. 11, 49196 Bad Laer "Ring beam formwork"

The innovation relates to a ring beam formwork that is based on

or can be attached to the masonry and serves to hold the concrete to produce the ring beam.

The innovation is based on the task of creating a ring beam formwork that allows the use of fibre cement panels

possible, is particularly stable and can be easily adapted to local building conditions.

This problem underlying the innovation is solved by the teaching of the main claim.

Advantageous embodiments are explained in the subclaims.

In other words, it is proposed that the

Ring beam formwork is limited by two fibre cement panels, which are held inside by screwed U-brackets made of sheet steel. The U-brackets can be adjusted to the height and width of the desired ring beam and the fibre cement panels create the possibility of

that the ring beam is made of exposed concrete, whereby the fibre cement panels can be fitted with additional glued fibre cement panels on the outside so that the screw connections are no longer visible.

The U-brackets used are made of galvanized sheet steel and have a corrugated profile, which makes it possible to insert a U-shaped structural steel bracket into the corrugations, which additionally increases the strength of the formwork, as it is no longer possible for the panels to bend outwards.

Furthermore, in one embodiment, skirting boards can be provided on the inside of the formwork, which are connected to the fiber cement panels on the one hand and can be glued or nailed onto the top of the masonry on the other. This ensures that the formwork is well secured and cannot be displaced relative to the masonry and at the same time the U-shaped brackets, which end at the top edge of the skirting boards, are kept at a distance from the top of the masonry so that the concrete to be poured flows under the U-shaped brackets. In addition, this also ensures that the

Reinforcement can rest on the U-brackets, thus guaranteeing an exact height of the lower edge of the reinforcement.

In another embodiment of the ring beam formwork according to the innovation, the fibre cement panels are placed on the outside of the masonry, which guarantees that they cannot be displaced and at the same time creates an abutment that effectively prevents the fibre cement panels from bending when the concrete is poured. 20

Examples of implementation of the innovation are explained using the drawings. The drawings show in

In the embodiment according to Fig. 1, the width of the ring beam formwork corresponds to the width of the masonry, and in order to prevent the ring beam formwork from moving on the masonry, baseboards 5 and 6 are provided, which are attached on the one hand to the inside of the fibre cement panels, and

for example glued, and which on the other hand are also attached to the top of the masonry 4, for example glued or nailed. Preferably, the height "h" of the skirting boards is 2 cm, while the width "b" of the skirting boards is 3 cm. Since the U-brackets 3 with their web on the

Upper edge of the skirting boards 5 and 6, a free space is created between the underside of the web 9 of the bracket 3 and the upper side of the masonry 4, which is designated in Fig. 1 with the height "h". The height "h" corresponds to the height of the skirting boards.

This design makes it possible for the concrete to be poured to flow under the lower edge of the web 9 of the stirrups 3. At the same time, however, the stirrups 3 also serve to support the reinforcement to be introduced into the formwork, so that a

exact height of the reinforcement is guaranteed.

The U-brackets 3 are designed with a wave profile, whereby a stabilizing bracket 8 can be inserted into the waves 7, which consists of a conventional structural steel profile and which can be

Particularly wide ring beam formwork prevents the upper areas of the formwork, i.e. the fibreboards 1 and 2, from bending outwards.

In the embodiment according to Fig. 2, the fibers

cement plates 1 and 2 downwards over the masonry 4, thus resting on the outside of the masonry 4. This simultaneously provides a shifting protection for the ring beam formwork. In this case too, however, the stirrups 3 with their web 9 can also serve to support the reinforcement, so

that here too an exact height of the reinforcement is guaranteed.

Additional fibre cement panels can be glued to the outside of fibre cement panels 1 and 2 so that the screw heads of the screws securing the stirrups are no longer visible and the outside of the ring beam formwork can simultaneously be designed as exposed concrete.
