Definitions
- the invention relates to a method for producing concrete spacers according to the preamble of patent claim 1.
- spacer body eg. When creating concrete walls and beams used to secure a defined distance between the formwork on the one hand and the reinforcement or the reinforcing mats on the other.
- the spacers also ensure that the reinforcement is covered with a certain layer thickness of concrete, the spacer being fully integrated into the cured concrete mass of the component.
- Cement-bonded spacers therefore have the elementary advantage over, for example, those based on plastics that they can be fully integrated in the concrete and thus do not represent any foreign bodies in the concrete.
- Concrete spacers are usually produced either in a casting process in different forms trained in mass or obtained in a concrete extrusion process.
- Another publication is a procedure ( DE-OS 34 42 918 ), in which a binding wire is inserted in such an extruded profile strand of cement-bonded material from one side and then cut off.
- spacers instead of, for example, to be carried out with an extruder extrusion process for the production of spacers, it is also known to produce spacers by a casting process in molds ( DE-GM 19 96 751 ). Such a molded product is clearly defined in its dimension and can not, like an extruded spacer, be made from a profile strand through sections of selectable length in individually different, needs-based dimensions. Such casting manufacturing of the spacers is relatively time consuming and costly over the extrusion process, but allows for an unrestricted design in terms of molding.
- spacer bodies in concrete casting is a widely used and proven technique in which each spacer originates from a separate mold. After entering the concrete into the mold holding body are inserted into the not yet fully solidified spacer, with which the spacer is attached at a later date then to be determined in their distance to a casing reinforcement.
- These may be metallic bodies such as retaining wires as well as plastic bodies which are designed, for example, as clamps.
- the published patent application DE 28 39 166 A1 to be named.
- the extrusion process provides that spacer bodies are extruded by machine, with considerable limitations in terms of shaping and other conditions for the introduction of holding bodies in the spacer body.
- Another aspect of the present invention is that experimentally working with spacers has shown that a roughened outer surface of a spacer body basically has a positive effect on the connection of a prefabricated spacer to the in-situ concrete, for example, in a concrete wall, still as liquid concrete is brought into connection with the already cured spacer.
- the cement paste applied externally to casting bodies counteracts an ideal chemical-physical connection of the preproduced spacer with the in situ surrounding concrete in the later concrete wall to some extent, thereby increasing the risk of immigration of chemical substances in a fine gap area between spacer body shell and surrounding in-situ concrete is favored.
- the spacers which are later broken off from the plate, primarily have the features of conventionally cast casting moldings, in particular a largely smooth lateral lateral surface which only permits limited access to the in-situ concrete. The result is only a very narrow breaking edge, which should have a broken structure.
- the JP2002317526A a spacer body integrally molded in concrete and forming a joint of the plurality of spacers via connecting parts in a longitudinal direction.
- the connecting part is formed between recessed grooves between the spacers, which are provided at the same depth, wherein by breaking the connecting parts individual spacers can be broken from the strand.
- the object of the present method to simplify the production of spacer bodies on the one hand and thus to allow an acceleration of the manufacturing process, especially in mass-produced spacer bodies.
- the connection of the spacer with the in-situ concrete is also to be improved in that the finished spacer body has a rough surface and thus better teeth of the spacer body on its outer shell with the in-situ concrete is possible.
- the method according to the invention for producing the concrete spacer body provides for different process steps that take place one after the other.
- the starting material for the later spacer body namely a plate-shaped cast concrete cuboid
- this pre-produced flat cast concrete slab makes it possible to break this slab later into the individual spacer bodies, for which reason predetermined breaking points in the cast concrete slab are expediently introduced via the casting mold, which correspond to the later mechanical cleaning of the break edges of the spacer bodies.
- the bottom plate of the mold for the base plate to be crushed already has shapes in the form of depressions, which define the subsequent bearing surface of the spacer body on a shuttering wall and thus also the area later recognizable in exposed concrete.
- This is a strength conventionally produced in the casting process concrete spacers that here the bearing surfaces, points or lines can be produced very accurately and as desired.
- the inventive method now allows, despite the broken outer surfaces of the spacer body to produce a defined cast support point on the casing and thus on the outer surface of the concrete building.
- This can be done in the form of a point contact point or in the form of several projections or a small contact surface.
- This is basically any shape design on the definition of the bottom plate of the mold possible.
- the bottom plate of the mold comprises, according to the number of the spacer to be broken from the mold a corresponding analog number of wells to form the support surface in the desired shape, wherein the wells are each assigned to a broken in the last step from the plate spacer, whereby the arrangement of these wells , the placement of the spacer fastening means in the concrete slab and the course of the fault lines in the production of the individual spacers from the plate in coordination with each other
- the fastening means are introduced. These are introduced on the upper side into the surface of the cast starting plate and arranged according to the number of spacer bodies to be broken in a defined grid.
- this introduction of the fastening means is carried out automatically in the surface of the not yet cured cast concrete and after a precisely predetermined grid.
- the method according to the invention allows a maximum of automation. That is, it is intended to perform the filling of the molds with the cast concrete, the loading of the molds with fastening means as well as the breaking of the spacers from the plate automatically on corresponding conveyors such as conveyor belts and the like.
- the starting plate is completed in a maturity, which allows the actual breaking of the spacer body.
- the plate of a machine device for breaking the concrete slab is fed into individual sections, ideally also automated via conveyor belts.
- a solution according to the invention provides in this case that the plate is broken in a first step in the transverse or longitudinal direction by a linear breaking device in strip sections. These strip sections, which are now arranged parallel to one another, are fed in a second method step to a further linearly extending breaking device, which is arranged approximately at right angles to the first breaking device and thus breaks cuboidal or rectangular spacer bodies of the desired size into the strip-shaped sections of the cast concrete slab.
- Guiding means are provided for this purpose, which press the strip-broken sections of the starting plate against one another and feed them to the next method step and thus also convey the starting plate in the method.
- the voltage is registered in the region of the overlying grid lines in the cast plate and there are defined breaklines, which extend approximately vertically through the cast plate and thus break the desired spacer body out of the plate. In this way, a complete plate can be broken into individual spacers advantageously with a single step.
- the feet serving as shuttering surfaces later are variable in that the bottom plate of the casting mold is designed to be interchangeable.
- a variety of bearing surfaces of the spacer bodies can be realized.
- the height of the starting plate and thus the depth of the later spacer body and thus the distance between the casing and reinforcement can be according to the invention about 5-20 cm. This allows use of the spacer body in many technical applications and in a multitude of later realizable concrete structures.
- the invention provides, in the first method step, to feed the starting plate onto a conveying means of the fracture device. This is arranged transversely to the conveying direction of the starting plate above the conveyor in an advantageous embodiment of the method, wherein the output plate passed through the width of the spacer body to be broken under the strip-like breaking device thus gradually producing the strip-like portions of the starting plate.
- this now present in strips output plate is pressed together by holding arms and out, which are also arranged transversely to the original conveying direction and thus compress the generated strips of the output plate in the original conveying direction together.
- these strips which are pressed together in a plate-shaped manner by the holder arms, are then broken transversely to the original conveying direction. This is done either directly via the previous funding or the held output plate is continued transversely to the original conveying direction and fed to a second breaking device, which breaks transversely to the first breaking device, the now strip-shaped sections of the original output plate in single body. Finally, then these broken spacer body can be fed directly to a further promotion, for example in packaging units, such as transport bags or the like.
- the novel spacer body according to the invention which are characterized in that they are at their side in a concrete building all-round peripheral edges are formed from broken concrete planks.
- the contact surfaces to the shuttering are produced by casting and thus formed in their shape variable and uniform and thus provide clean and aesthetically pleasing support points or - surfaces on the outside of a concrete structure.
- the armoring pointing, provided with fastening means areas of the spacer body also have not broken and smooth surfaces, as here also no breakage occurs. That is, the opposite mounting surface to the reinforcement as well as the support surface to the shuttering have defined attractive and functional surfaces.
- the lateral surfaces of the spacer body, with which the connection has to be made in the concrete building are roughly broken and thus ideal to ensure a connection between the castable concrete and the already prefabricated spacer bodies. Pollutant input through the fine gaps formed between, for example, conventional cast spacer bodies between the prefabricated spacer body and the later cast concrete can thus be avoided.
- the spacers according to the invention by the method according to the invention meet the highest requirements, especially in use in concrete structures, for example, should have existed in the sea, since in particular here the corrosion of the reinforcements installed in concrete represents a difficult solvable technical problem.
- the circumferential surface of the broken spacers has a height of at least 50% of the thickness of the concrete slab. That is, the spacers are broken from a full-surface plate, which has smooth casting areas only in the region of the bearing surfaces to the shuttering, resulting in correspondingly formed recesses in the mold. But it is The aim of the method as well as the resulting spacer body, that the lateral surface is formed circumferentially and broken over a large area in order to effect the desired connection with the later cast concrete. This is achieved according to the invention without expensive post-treatment of the spacers by the breaking process from the full-surface plate.
- the concrete slab is prefabricated as a starting material for a large number of later spacers.
- the fasteners 2 used are attachment wires, which are arranged in pairs in the spacers.
- 1 rupture lines are recognizable on the surface of the concrete slab, the grid-like cover the concrete slab 1 and each define a later spacer.
- FIG. 2 The concrete slab 1 according to the invention is also shown in a side perspective view, wherein the protruding from the top spacer fasteners 2 can be seen as well as extending on the underside of the concrete slab 1 contact surfaces 3, which are formed in this case half shell-shaped and thus a roughly produce punctiform uprising in the finished concrete product.
- the height ratio of cast and thus smooth-walled footprint 3 and later broken from the concrete slab 1 lateral surfaces between footprint 3 and the smooth top with fasteners 2 is approximately 1 to 2 and thus the broken
- the lateral surface on the spacer makes up about 70% of the total height.
- the desired binding effect to in-situ concrete is ensured over a large area.
- This can also be square, round and flat. It can also consist of several, for example 3 or 4 feet, form a pyramidal or star-shaped footprint.
- FIG. 3 shows that on the top of the concrete slab such predetermined breaking joints 4 are arranged in an exemplary representation square to each other running in a grid.
