CASTING MOLDING STRUCTURE

The invention relates to a reinforcement structure for forming and prefabricated a mold of an outer surface of a structure, comprising a first reinforcement part fixed to the casting mold and a second reinforcement part adapted to be fastened to said first reinforcement part. Reinforcement structures of this type are used in self-supporting molds in the manufacture of, for example, reinforced concrete composite structures.

In the self-supporting casting mold 10 described in FI patent publication 74100, the reinforcement forming the reinforcement of the building part and acting as the support structure of the casting mold is made of T-profile rods attached to the inner surface of the casting mold. The reinforcement consists of flat reinforcing parts, of which the first reinforcing part is fixed to the casting mold and the second reinforcing part is fixed to the first reinforcing part perpendicular to the first reinforcing part.

Reinforcement of in-situ cast structures is generally made of brush and / or round steels, which are fastened with metal wires to form a uniform reinforcement. The loose metal wire 20 is then wrapped around the steels to be joined at the intersection of the steels. Reinforcement work is a slow and precision work phase.

In the solution according to the invention, for example, the conventional brush or round steel reinforcement of the building component is combined with the reinforcement attached to the inner surface of the self-supporting casting mold, which can then also be reduced. The reinforcement structure according to the invention makes it possible to diversify the reinforcement options of the self-supporting casting mold. The reinforcement structure is characterized in that at least one fastening member for said second reinforcement part is arranged to be fastened to said first reinforcement part 30, which is fixed to the casting mold, or vice versa.

In the solution according to the invention, fastening members are fastened to the reinforcement of the casting mold, for example 2 82514, fixed to the wall of the casting mold, e.g. for fastening brush and / or round steels. The use of ready-to-use fastening members considerably speeds up the reinforcement work 5 and, on the other hand, ensures that sufficient fastening is achieved. The weight of the molds is also reduced, which makes it easier to transport the molds.

The invention will now be described in detail with reference to the accompanying drawing, in which Figure 1 shows an embodiment of the invention using a wire-like fastening member and Figure 2 shows another embodiment of the invention using a tongue-shaped fastening member.

The casting mold, which is only partially shown in the figures, is denoted by reference numeral 1. A first reinforcement part 3 is attached to the wall of the casting mold, its inner surface 2, in this case a substantially rectangular, flat-skinned steel profile bar. The reinforcing part 3 can be of other shapes, it is only essential that it is attached to the casting mold and that it supports the casting mold in the erect position of the mold. The reinforcement part 3 forms part of the reinforcement of the building part.

The reinforcement structure further comprises a second reinforcement part 6, which is placed in place when the mold is erected. In this case, the reinforcing part 6 consists of a rod-like member, a brushed steel bar, arranged parallel to the first reinforcing part 3. In the structure according to Fig. 1, the reinforcement part 6 rests on the first reinforcement part 3, to which it is attached. The reinforcement part 6 can also be placed at a distance of 30 from the reinforcement part 3, as shown in Fig. 2. The reinforcement part 6 replaces the flange part of the T-profile reinforcement previously attached to the casting mold already in the prefabrication stage. By producing ready-made fastening members for the second reinforcement part 6 instead of reinforcement, the mold is considerably lighter.

In the case of Figure 1, wire-like members 5, preferably metal wires, are attached to the edge 4 of the first reinforcement part 3 at a distance from the inner surface 2 of the mold 1, by means of which the second reinforcement part 6 5 is attached to the first reinforcement part 3. 3 to edge 4. Of course, welding is not the only option, although it is easy from a manufacturing point of view.

Figure 2 shows a tongue-shaped fastening member 5, which is preferably integral with the first reinforcing part 3 and is formed on the edge 4 of the reinforcing part 3. The tongue 9 of the fastening member 5 is bent into a U-shape with a second notch formed by U flanges and a web. the reinforcing part 15 is fitted and fixed when the mold is erected.

At the second edge 7 of the profile bar attached to the casting mold 1, openings 8 are formed in the mold 1 for a mass to be cast, such as a concrete mass. The mass to be cast is adapted to move from the openings 8 on both sides 20 of the reinforcement part 3 to ensure the attachment of the reinforcement part and to form a continuous casting component.

The fastening member 5 is dimensioned so that it can withstand the stress caused by the erection of the mold 1 and the pressure caused by casting. The mold 1 with its support structures, i.e. the reinforcements of the building part 25, supports the weight of the building parts before the cast mass binds and hardens into a finished composite structure.

The invention is not limited to the embodiments described above, but can be modified within the scope of the appended claims 30. For example, the fastening member can alternatively be fastened to the second reinforcement part 6.
