Description

FIELD OF THE INVENTION

[0001] The invention relates to a storage arrangement according to the preamble of claim 1. The storage arrangement accordingly serves for storing reinforcement elements. The reinforcement elements are intended for reinforcing a concrete structure, in particular in the region of the transition between a first concreting section and a second concreting section adjacent to the first concreting section. The reinforcement elements are arranged in or on the storage arrangement in a movable and / or bendable and / or screwable manner.

[0002] According to the preamble of claim 11, the invention further relates to a method for producing a storage arrangement described herein.

[0003] The invention also relates to a concrete structure according to the preamble of claim 13.

[0004] The concrete structure therefore comprises a first concreting section and a second concreting section adjacent to the first concreting section. Reinforcement elements are arranged in the area of the transition between the first and second concreting sections.

[0005] Finally, the invention relates to a concrete structure manufacturing method according to the preamble of claim 14.

[0006] The method is used to produce a concrete structure comprising a first concreting section and a second concreting section adjacent to the first concreting section. The concrete structure can be constructed according to a concrete structure described herein. TECHNOLOGICAL BACKGROUND

[0007] The transition area between two adjacent concreting sections of a concrete structure includes a joint, and this joint is considered to be less structurally stable than monolithic components without a joint. Therefore, additional reinforcement is required in the contact or transition area between adjacent concreting sections and the joint. This is achieved with reinforcement elements or reinforcing bars. To simplify the processing of the reinforcing bars in the joint area, retaining boxes are used. The reinforcing bars are arranged in such a way that they can be bent out of the box or screwed into place, especially when the first concreting section is complete and the second concreting section is to be connected to the first.

[0008] To improve the static properties of the joint area, particularly with regard to the transfer of shear forces, the retaining boxes are intended to contribute to the interlocking of the concrete and reinforcement components involved. The joints with the retaining boxes installed therein can have the properties "very smooth," "smooth," "rough," or "toothed," with a "toothed" joint being able to transfer the most shear forces. To create a joint with the "toothed" property, the retaining boxes are equipped with profiled or structured wall sections so that shear forces can be better absorbed or transferred. The retaining boxes designed in this way can preferably transfer shear forces in one direction. If shear forces are to be transferred in both the lateral and longitudinal directions (relative to the construction joint), the retaining box components require a complex design, which is associated with comparatively high (manufacturing) costs.This is where the invention comes in.

[0009] Document CH 697 491 B1 discloses a custody arrangement according to the preamble of claim 1. DESCRIPTION OF THE INVENTION

[0010] Against this background, the object of the invention is to improve the static properties of concrete structures with multiple concreting sections in the area of the joint between two adjacent concreting sections with the lowest possible material and cost expenditure. This object is achieved by a retaining arrangement according to claim 1. Further embodiments arise from the subclaims. The retaining arrangement according to the invention is characterized in that claw elements are arranged in or on the wall section, which protrude from the wall section in at least one direction. The claw elements are designed as pins or bolts. The claw elements bring about a stable connection or claw engagement with the concrete of the concrete component, in particular for absorbing / transmitting transverse forces.Due to the effect of the interlocking elements of the retaining arrangement, a joint between the adjacent concreting sections is created that achieves the quality characteristic "interlocked," i.e., the highest quality level—and this applies to shear forces acting both longitudinally and transversely to the joint. Depending on the region or standard, particularly in Switzerland, the term "positive-locking" is also used for this highest quality level.

[0011] The storage arrangement is formed as a storage box comprising a profile with a substantially U-shaped cross-section.

[0012] The storage box comprises a wall section forming a rear wall and wall sections arranged laterally on the rear wall, which form side walls. The claw elements are arranged on or in the rear wall. A front wall section or an insert element can be provided on the front sides of the storage box. The reinforcement elements are preferably arranged in or on the rear wall, preferably near the side walls. The claw elements can be arranged in or on the rear wall between the reinforcement elements, for example in the region of the center of the rear wall. At least one wall section of the arrangement can comprise at least one profiled and / or perforated and / or toothed and / or embossed surface.

[0013] It may be expedient for the pins or bolts on one side of the rear wall to protrude from the storage box. According to the invention, the pins or bolts on the other side of the rear wall protrude into the storage box.

[0014] The part of the pins or bolts that protrudes into the storage box has a length that corresponds to or almost corresponds to the dimensions of the side walls and therefore to the height of the storage box. If the storage box includes a lid that can be arranged on the side walls, the pins / bolts will not fall out during transport of the storage box. On the construction site, the storage box, together with the lid, is arranged in or on a concreting section. Once the concrete in this concreting section has hardened, the lid is removed and the reinforcement elements can be bent out of the storage box. The second concreting section, directly adjacent to the first concreting section, can then be arranged in or on the opened storage box.The parts of the pins / bolts that extend into the retaining box contribute to better interlocking in the area of the joint between the first and second concreting sections, as the pins / bolts better transmit shear forces transversely and longitudinally to the joint. The pins / bolts arranged in openings in the rear wall cannot fall out of the retaining arrangement when handling the box, as the pins / bolts are prevented from falling out by the box lid before the first concreting section is arranged. When the second concreting section is arranged, the pins / bolts are already fixed in the first, hardened concreting section.

[0015] On the wall section with the locking elements, particularly in or on the rear wall, approximately 10 to approximately 100 locking elements can be arranged per square meter of wall section area. With this areal density of locking elements, high-quality locking is achieved while simultaneously reducing material and manufacturing costs. Using locking elements, the locking arrangement can be made smaller; in particular, the installation depth of the locking arrangement is reduced, for example, in the range of approximately 1 cm to approximately 4 cm.

[0016] The claw elements are preferably formed as pins or bolts, in particular cylindrical or circular-cylindrical or cylinder-like or circular-cylinder-like. The pins / bolts can have a non-circular cross-section, in particular a polygonal cross-section, for example a triangular, square, or hexagonal cross-section. The cross-section or cross-sectional area can change over the length of the pin / bolt, for example so that the pin / bolt is conical. The pins / bolts can be fastened to the wall section, for example by means of a welded connection. The pins or bolts can be arranged on at least one side of the wall section, preferably on both sides. In this respect, the pins / bolts can be arranged on the front and / or rear and / or inside and / or outside.

[0017] The pins or bolts can have at least one thickened portion. They can have a region with a first diameter and a region with a second diameter, wherein the first diameter is larger than the second diameter. The pins / bolts or the pin / bolt cross-section can include a shoulder and / or a step. The pins / bolts can have a chamfer and / or at least one rounded portion on at least one end face.

[0018] The pins / bolts can be arranged in openings, in particular circular ones, in the wall section, in particular in a form-fitting and / or force-fitting and / or material-fitting manner. For this purpose, bores are arranged in the wall section, the diameter of which corresponds to or almost corresponds to that of the pins / bores. The pins / bolts are inserted (manually or mechanically) into the bores. It can be expedient if the pins / bolts are fixed in place. The pins / bolts can have a diameter in a diameter range of approximately 6 mm to approximately 18 mm. The pins / bolts can have at least one thickened portion. A section or region of the pins / bolts can be provided with a first diameter and a region with a second diameter, wherein the first diameter is larger than the second diameter. The pins / bolts can have a length in a length range of approximately 15 mm to approximately 200 mm.The bolt length, for example, can be approximately twice the box depth. The dimensions of the pins / bolts are comparatively small compared to the dimensions of the storage assembly. This allows the storage assembly to be manufactured with minimal material expenditure while still meeting high quality standards.

[0019] The pins / bolts may protrude further from the hole on one side of the wall section than on the opposite side. The pins / bolts may protrude from one side of the wall section by a distance of approximately 10 mm to approximately 190 mm.

[0020] An improvement of the static properties of concrete structures with several concreting sections in the area of the joint between two adjacent concreting sections with the lowest possible material and cost expenditure is further achieved with a method for producing a storage arrangement according to the invention according to claim 11.

[0021] The manufacturing method provides for a plurality of holes to be drilled into a rear wall of the storage arrangement, and for a pin or bolt to be inserted into each hole. A cover is then placed on the storage arrangement so that the pins or bolts inserted into the holes cannot fall out of the holes. The pins or bolts may have at least one thickened portion and / or at least one structured area.

[0022] Improving the static properties of concrete structures with several concreting sections in the area of the joint between two adjacent concreting sections with the lowest possible material and cost expenditure is also achieved with a concrete structure according to claim 13. Accordingly, the reinforcement elements of the concrete structure are arranged in a storage arrangement described herein.

[0023] An improvement of the static properties of concrete structures with several concreting sections in the area of the joint between two adjacent concreting sections with the lowest possible material and cost expenditure is further achieved with a manufacturing method according to claim 14.

[0024] The method accordingly serves to produce a concrete structure described herein, comprising a first concreting section and a second concreting section adjacent to the first concreting section. The reinforcement elements are arranged in the method using a retaining arrangement described herein.

[0025] The aforementioned components to be used according to the invention as well as those claimed and described in the exemplary embodiments are not subject to any special exceptional conditions in terms of their size, shape, material selection and technical conception, so that the selection criteria known in the field of application can be applied without restriction.

[0026] Further details, features and advantages of the subject matter of the invention emerge from the subclaims, as well as from the following description and the associated drawing, in which - by way of example - an embodiment of a storage arrangement is shown. BRIEF DESCRIPTION OF THE CHARACTERS

[0027] In the drawing show Fig. 1A - Your first variant of a storage arrangement in different views, Fig. 2A - Your further variant of a storage arrangement in different views and Fig. 3 a schematic view of a claw element formed as a bolt. DETAILED DESCRIPTION OF EMBODIMENTS

[0028] The Figures 1A to 1D show different views of a storage box 1 for concrete reinforcement elements. Fig. 1A shows a perspective view of the interior of the storage box 1, in which the reinforcement elements 2 comprise V-shaped bars. The reinforcement bars 2 each have a bending area 3, so that a section of each bar can be stored in the cavity 4 of the box 1. On the construction site, where the concrete structure is to be erected, the bending areas 3 of the bars 2 can be bent out of the box 1. On the back 5 of the box 1 ( Fig. 1C), the reinforcement elements 2 are formed in a U-shaped manner. The stirrups 6 protrude essentially vertically from the rear wall 7 of the box 1. The reinforcement elements 2 are manufactured or arranged in the box 1 by inserting the stirrup-shaped reinforcement bars 2 through the rear wall 7 of the box 1. The box 1 is formed from a U-shaped profile, preferably a metal one, with the rear wall 7 being wider than the narrow side walls 8 of the box 1.

[0029] In the detailed views according to the Figures 1BThe claw elements 9 can be seen in 1D (front) and 1D (back), each of which is formed as a bolt, and which extends through an opening 10 in the wall section of the box 1 forming the rear wall 7, so that the bolts 9 protrude from the rear wall 7 on both sides of the box 1. During concreting, the bolts 9 form a claw with the concrete surrounding the bolts 9, whereby the component joint in which the storage box 1 is arranged achieves the static quality level "interlocked" or "positively locked".

[0030] In the variant according to the Figures 2A to 2D the reinforcing bars 2 have no buckling area and extend on the front and back of the box 1 essentially perpendicular to its rear wall 7. In this variant, too, bolts 9 are provided as claw elements, which protrude from the front and back of the rear wall 7 of the box 1.

[0031] For both variants according to the Figures 1A to 1D and 2A to 2D The rear wall 7 of the storage box 1 is neither structured nor profiled. The rear wall 7 can therefore be manufactured from a cost-effective material. The interlocking to achieve the high quality level "toothed" is achieved with the pins 9 or micro-bolts 9. The bolts 9 can have a diameter of approximately 13 mm and a length of approximately 60 mm. The bolts 9 protrude approximately 30 mm from the plane of the rear wall 7 on the front and / or rear side 5. The distribution of the bolts 9 over the surface of the box's rear wall 7 increases the stability and static strength of the box 1, so that further measures to achieve a high quality level such as "toothed" are unnecessary.

[0032] The Fig. 3shows a schematic side (sectional) view of a claw element 9 formed as a bolt 9. The bolt has a region 11 with a first diameter at one end and a region 12 with a second diameter at the opposite end, the first diameter being larger than the second. The step or shoulder between the regions 11 and 12 forms a thickening 14 of the bolt 9. In the region 12 with the smaller diameter, adjacent to the step or shoulder, there is a region 13 of the bolt with a structured surface. The structure in the structured region 13 can be formed by roughening or embossing. The structured region ensures a better fit of the bolt in the opening 10 of the storage box 1. A chamfer is arranged at the end of the narrower region 13, whereby the bolt 9 can be better inserted into the opening 10.The thickening 14 ensures that the bolt 9 does not fall through the opening 10 when inserted into the opening 10. The length of the thicker area 11 essentially corresponds to the dimension of the narrow side 15 of the storage box 1. LIST OF REFERENCE SYMBOLS
