Description

Concrete element and method plus application hereof.
The invention relates to a concrete element with at least one anchored including embedded wire including steel wire for joining with other concrete elements.
The invention also relates to a method of manufacturing concrete element created by application of a mould with at least one anchored including embedded wire including steel wire for joining with other concrete elements.
The invention furthermore includes application of concrete element with at least one anchored including embedded shape stable wire.
From DK/EP 0914531 T3 is known a device and a method of manufacturing concrete elements with embedded steel wire, which is used for joining with other preferably similar concrete elements.
The joining of the concrete elements occurs when the steel wires from two concrete elements, which are to be joined, are connected e.g. by insertion of a steel rod where after the cavity between the concrete elements is filled with concrete.
In order to transport guard the embedded steel wires these are embedded in the concrete elements with a fixation box, which has some folded side surfaces, which are used to hold the steel wire bended together during transport.
The hitherto used traditional steel wires are not shape stable and will therefore extend and protrude outside the end surfaces of the concrete elements if they are not fastened in a fixation box. If the wires protrude from the end surfaces of the concrete elements there is a high risk that they will be destroyed during transportation, e.g. by being squeezed or made deformed by contact with another material.
If a wire is damaged during transport it will be weakened and can therefore not meet the strength demands, which are specified when the wire subsequently is to be used for joining of the concrete elements at the construction of a building work.
It is therefore necessary with the hitherto used type of steel wires that these are fastened in special fixation mechanisms during transport. If not, the risk of damaging the wires is high.
When the concrete element after transport is placed at its destination and is to be connected with another concrete element, the wire is released from the fixation box, which then remains embedded in the concrete, which is filled into the space between the two concrete elements.
It has been found, however, that this prior known technique involves some drawbacks including that it is relatively expensive to manufacture a component, which partly consists of the joining steel wire itself and the fixation box, which is used to position and protect the steel wire during transportation.
It is also inappropriate to use resources including both time, energy and materials on manufacturing and embedding a fixation box, which is solely used to protect the wire during transport, but has not got any function when the concrete element is joined with another concrete element.
It is therefore an object of the invention to improve the known technique including concrete element, method and application. The object of the invention is achieved by a method of the type stated in the introductory portion of claim 1 , which is characterized in that the anchored wire is shape stable.
In this way it thus becomes possible to bend the wire together such that it does not protrude from the concrete element during transport and thereafter simply to fold out the wire when it is to interact with another nearby wire at the joining of two concrete elements.
Hereby, application of a wire fixation box is fully avoided whereby the product is significantly simplified and is made less costly.
Further preferred embodiments of the concrete element are stated in claims 2 to 5.
As mentioned the invention also relates to a method.
This method is characterized in that a shape stable wire is used to the anchoring including the embedding, which in advance of the anchoring is fit into an opening device, which can be provided with a magnet for fastening of the opening device to the casting mould, where the opening device, after hardening of the cast concrete, is removed and where the opening device can thereafter be reused.
Hereby it becomes possible, inexpensive and efficient to manufacture concrete elements with embedded joining steel wires with a low consumption of material and a high degree of reutilisation.
Besides being economically attractive the method is hereby also more environmentally friendly than the hitherto known technique. As mentioned the invention also relates to the application of concrete elements with at least one anchored including embedded shape stable wire for building constructions.
The invention will now be explained more fully with reference to the drawing, in which:
Fig. 1 shows a cross-section of a concrete element with embedded shape stable steel wire and opening device.
Fig. 2 shows that same device as fig. 1 but with the opening device partially lifted from the element.
Fig. 3 shows the same device as fig. 2 but with the opening device additionally lifted up from the element.
Fig. 4 shows a cross-section of a concrete element with a vertically positioned shape stable steel wire embedded in an opening.
Fig. 5 shows the same device as fig. 4 but with the shape stable steel wire bended into the opening.
Fig. 6 shows a shape stable steel wire inserted into an opening device.
Fig. 7 shows in a cross-section of the longitudinal axis a wire.
Fig. 8 shows in a cross-section of the longitudinal axis a wire with a shape stable attachment.
Fig. 9 shows in a cross-section of the longitudinal axis a wire where a wire part is shape stable.
Fig. 10 shows a cross section of the longitudinal axis a wire with a shape stable core.
In fig. 1 is shown a cross-section of a concrete element 1 with a wire 2, which is anchored to the concrete element 1 by embedding.
An opening device 3 is also seen shaped with tracks 4 for encasing of the wire 2.
In fig. 2 is shown the same cross-section of a concrete element 1 , which is also depicted in fig. 1 , but where the opening device 3 is partially released from the concrete element 1 and where the wire 2 is vertically positioned in relation to the concrete element 1.
Below the partially uplifted opening device 3 is seen an opening 5, which is formed by the opening device 3 during the casting of the concrete element 1.
In advance of the casting of the concrete element 1 , the opening device 3 with the in the track 4 inserted wire 2 is placed in the casting mould, which forms a basis for the finished concrete element 1.
The opening device 3 with the inserted wire 2 can in a preferred embodiment be fastened to the concrete element casting mould by application of a magnetic clutch including by adding and mounting a magnet to the opening device 3 in the surface which faces the concrete element casting mould, as long as the casting mould contains a magnetic material such as iron. In fig. 3, the opening device 3 is additionally released from the concrete element 1 whereby the opening 5 is clearly visible.
The opening device 3 is in fig. 6 depicted with an inserted wire 2, which in the opening device 3 is controlled by the track 4.
In fig. 6 is furthermore seen the end part 6 of the wire 2, which is anchored to a concrete element preferably by casting.
By manufacturing the opening device 3 in a polymeric material such as a rubber the opening device can be reused for several wire castings.
Fig. 4 shows the concrete element 1 with the embedded wire 2, which is placed in the opening 5.
In fig. 4 the wire 2 is vertically positioned in relation to the concrete element 1 , which is the state in advance of assembly with another concrete element.
In fig. 5 is seen the same device as depicted in fig. 4 but with the wire 2 bended down in the opening 5, which is the ideal state at transportation since the wire thereby lies protected in the opening 5.
A precondition necessary for the wire 2 to fasten the shape as depicted in respectively fig. 4 and fig. 6 is that the wire 2 is shape stable.
Fig. 7 shows a cross-section of the longitudinal axis of a traditional non shape stable wire including steel wire, which consists of the in example seven shown windings, which can e.g. be created from e.g. 19 threads.
The seven windings / wrappings 7 are twisted around a center material 8, which is preferably manufactured from a polymeric material. In fig. 8 is, as in fig. 7, shown a cross-section of the longitudinal axis of a wire, which is manufactured with seven windings 7 around a center material 8, but where a shape stable thread 9 is placed parallel to the wire.
The shape stable thread 9 can e.g. be a shape stable steel thread, which is fastened to the wire with straps, bands or wrappings.
By adding the shape stable thread 9 to the wire as shown in fig. 8 it can be achieved that wire and thread together are sufficiently shape stable, such that the wire can be fastened in positions as shown in respectively fig. 4 and fig. 5.
Fig. 9 shows another possible construction of a shape stable wire consisting of seven wrappings, which are twisted around a center material 8, of which the six are traditional wrappings 7 consisting of e.g. 19 individual threads but where at least one wrapping 10 is manufactured from a shape stable material such as shape stable steel or iron.
The shape stable wrapping 10 can be manufactured from a single thread or consist of a number, e.g. 19, joined threads including threads that are wrapped together.
In fig. 10 is shown a cross-section of the longitudinal axis of a wire, which is manufactured with seven wrappings 7 around a shape stable core 11 , whereby the total / assembled wire is shape stable.
The shape stable core 11 can also be manufactured by a single thread or consist of a number, e.g. 19, joined threads including threads that are wrapped together. It is part of the invention that concrete elements 1 manufactured with at least one anchored, including embedded shape stable wire 2, is used for building constructions.
