Sample registration - Otto Mühlbach ^ ö Dortmund-Aplerbeck «

Device for holding together the parts of a formwork for the production of concrete walls.

The subject of the utility model is a device for? Holding together, or connection and fastening of the parts from which the formwork required for the production of concrete walls is formed, namely the crossing timbers forming the formwork framework and the formwork panels to be attached to the framework.

According to the vheuerung of the utility model, the device consists of a spamming bar, which can be inserted on both sides of a scaffolding timber into the joints formed by two adjacent formwork panels on the one hand and by two crossing scaffolding timber on the other, bent at an angle, the butt edges of the formwork panels overlapping ends and xtlB ± at its the other end has an opening for receiving a clamping wedge on the outside of the formwork.

By using these bridle bars to hold them together or for fastening and connecting the formwork parts, the following advantages arise:

Ea no or very few nails are needed and the "De-nailing work required when dismantling the formwork is unnecessary, so that the labor that is freed up as a result can be used for other work. There are no accidents caused by nail work, because ä ± b jfctxsk the nails are replaced by the stirrups.

The clamps can be used indefinitely, while the nails can only be used once.

The formwork elements can be up to 30 square meters on level ground Assembled size; mnd in place by crane be transported, so that auxiliary scaffolding is required for a local Formwork with nails are required, are not required. This is the expended for the production of the formwork Significantly reduced working time With the tensioning brackets of the utility model, the formwork can also be used locally be made when circumstances require.

A significant advantage of the use of tension brackets according to the utility model Formwork parts held together also exist in that the formwork elements can be attached to the outside of the concrete walls to be produced without dismantling the same can be used from floor to floor.

According to the innovation, the clamping bracket can be U-shaped curved round bar iron with angled leg ends and a leg spacing, corresponding to the size of the scaffolding timber covered, and can be tensioned using a hardwood wedge.

According to "another version" the clamp consists of one slit at one end and angled on both sides Flat iron with a slot opening at the other end for the insertion of an iron wedge. Both clamping bracket shapes enable the fixed connection of the Formwork panels as well as the perpendicular and horizontal "square timbers with each other with the same mode of operation. By inserting of the clamping bracket between the formwork panels and the horizontal squared timber is also used to lead through the tie-rods required for the production of the concrete walls, which were drawn into the formwork before concreting The clamps themselves are only used to hold together the formwork parts.

The drawing illustrates two exemplary embodiments Shapes of the clamp according to the innovation of the utility model.

As Figure 4 shows, the formwork consists of vertical scaffold edge timbers 1, horizontal gel framework edging wood 2 and the formwork panels 3 attached to the edge wood 1

are held together, connected to one another and fastened to one another by tension brackets3J4j of the shape illustrated in Fig. 1, which encompass vertical edge timber 1 on both sides ^ are inserted into the joints between two adjacent formwork panels 3 and two horizontal edge timbers 2.

Instead of the U-shaped tensioning illustrated in Fig. bracket 4, which is formed from a rod round iron> two clamps 7 made of flat iron can be used as shown in Fig. 2, on both sides of a vertical timber 1 in the joints between two formwork panels 3 and two horizontal edge timbers 2 are inserted. The flat iron brackets 7 are cut at one end and the through the Incision formed flaps 8 are bent to opposite sides to claws, which the ICanten strips of Formwork panels 3 overlap.At the end protruding over the edge timbers 2, the flat iron bracket 7 has a Slot-shaped opening 9 for the insertion of a flat iron wedge 10 "illustrated by Fig. 3"
