Definitions
- the invention relates to a fastener with the features of the preamble of claim 1.
- fasteners made of metal and plastic such as anchor bolts, sleeve anchors, concrete screws or frame dowels are often used, which are fixed in the ground in a borehole.
- fastening means show, for example, the documents DE 10 2004 053 255 A1, DE 10 2006 053 226 A1, DE 10 2005 058 391 A1 and DE 101 29 733 A1.
- anchors are known with adhesive mass, which are connected in a borehole through the adhesive mass to the ground.
- concreting systems are used in which the fasteners are inserted into a formwork prior to the introduction of concrete and connected by pouring concrete with the substrate.
- fasteners are designed to transfer the largest possible forces from an attachment in the underground.
- the forces are forces acting parallel to the axis of the fastening element, that is to say tensile and compressive forces which act partly centrically in the axial direction of the fastening elements, but also by forces which act perpendicular to this axis.
- said fasteners are also used for attachment of facade structures. It often happens that parts of the facade, which are located in front of a thermal insulation layer in the outer area, are fastened with the fasteners in the ground, which lies behind the insulation layer. This penetrate the
- the fastener is a cast-in anchor made of a material of low thermal conductivity.
- a material with low thermal conductivity is considered according to this document, a plastic, in particular a polyamide, which may be reinforced by fibers.
- the embedment anchor consists of a sleeve with a
- the fastening element also consists of a fiber-reinforced plastic and is rod-shaped. It has at one end a bore extending in the axial direction as load engagement means for receiving a fastening means, for example a bolt anchor, a screw or a in the
- Fastener glued anchor The fastener itself is fixed in a borehole in the ground with an adhesive mass. It penetrates the insulation layer completely. In order to keep the heat losses through the fastener as small as possible, the bore for receiving the fastener ends in the insulating layer and does not reach to the ground. Thus, here too
- An also rod-shaped fastener shows the document DE 10 2006 052 648 A1. It is an anchor made of steel, which with a
- Adhesive mass is fixed in a borehole in the underground.
- the anchor is at least partially enveloped by a plastic, for example a polyethylene terephthalate (PETP), which forms a large-area insulating jacket.
- PETP polyethylene terephthalate
- the object of the invention is therefore to propose a fastener, which continues to be a significant reduction in the heat transfer large forces of a
- the fastening element according to the invention for transmitting centric tensile forces with a load application means has an anchoring area with a load transfer area and an insulating area.
- Transfer of forces from the fastener into the substrate is made of a material with a compressive strength greater than 0.5 N / mm 2 . This ensures that relatively large forces can be absorbed by the fastening element and transferred to the underground via the load transfer area of the anchoring area. Based on the realization that not all areas of the
- the anchoring area also has an insulating region, which consists of an insulating material whose thermal conductivity is less than 0.20 W / (mK), in particular less than 0.15 W / (mK).
- the insulating material may have a compressive strength which is lower than the compressive strength of the material in the load transfer area. It is irrelevant whether the insulation is introduced with the fastener or subsequently into the ground.
- the insulating material can be arranged directly on the fastener, or after the
- Insertion of the fastener for example, by foaming, are attached to the fastener.
- the thermal conductivity the ability of a substance to transport energy in the form of heat, is defined in this context as the heat flow of the one
- the thermal conductivity is about 0.24 W / (mK) and for a fiber-reinforced plastic at about 0.35 W / (mK).
- Typical insulation materials like
- polystyrene insulation panels or mineral wool are included in one area
- the compressive strength in this context is the force per area in Newtons per square millimeter (N / mm 2 ), which can absorb a pressure-resistant material virtually compression-free.
- the compressive strength of steel is about 250-1000 N / mm 2
- hard foam insulation panels have a compressive strength which is less than 0.1 N / mm 2 .
- centric tensile force is meant a force that places the fastener as a whole under tensile stresses without causing an additional moment to be absorbed by the fastener
- an insulating material is used in the fastener according to the invention deliberately, which has a much lower thermal conductivity than plastic.
- subregions of the anchoring area can be made without insulation material, ie they can not form an insulating area.
- the anchoring area is thus subdivided into sub-areas for load transfer and / or insulation, which, depending on the task, consist of the material optimal for the task.
- the insulating region is at least as large as the load transfer region.
- the contact surface between the substrate and anchoring area which is not Dämm Siemens, kept as low as possible.
- the thermal conductivity of the insulating material is less than 0.1 W / (mK), in particular less than 0.06 W / (mK).
- the insulating material is thus an insulating material in the usual sense, with properties such as insulation of buildings, such as insulation boards made of hard foam or
- An insulation material can in this context, be a subsequently introduced into the anchoring area foam, such as a polyurethane foam.
- the insulating material has a compressive strength which is greater than
- Compressive strength of the insulating material is greater than 1, 0 N / mm 2 , in particular greater than 1, 3 N / mm 2 . These values are given for example by a foam glass, the Perinsul-
- Compressive strength can absorb large forces and transferred to the ground. He prevents by its low thermal conductivity that heat or
- the fastening element according to the invention can be fastened in a borehole.
- Figure 1 shows a first inventive fastener in a substrate with an attachment in a sectional view
- Figure 2 shows a second inventive fastener in one
- Figure 1 shows an inventive fastener 1 for transmitting centric tensile forces, which is anchored as a bolt anchor 2 in a borehole 3 in a substrate 4.
- an attachment 5 is attached.
- a thermal separation layer 6 is arranged, which prevents a transfer of heat between the attachment 5 and the substrate 4.
- the attachment 5 has a through hole 12 through which the fastener 1 is inserted.
- the fastening element 1 has a load application means 7 and an anchoring area 8.
- the load engagement means 7 is formed as an external thread 9, onto which a nut 10 is screwed, with which a washer 11 is pressed against the attachment 5 and this is thus braced against the thermal release layer 6 and the substrate 4.
- the anchoring area 8 adjoins the load application means 7 in the direction of insertion and has an insulation area 13 with an insulation material 14, a first load removal area 15 and a second load removal area 16.
- the Dämm Scheme 13 is the cross section of the fastener 1 relative to the
- the insulating material 14 Dämm Scheme 13 which is at least as large as the load transfer area 15, 16, the contact surface 17 is reduced between the steel-made load-bearing areas 7, 15, 16 of the bolt anchor 2 and the borehole 3, whereby the heat transfer between fastener 1 and substrate 4 is reduced.
- the insulating material used here can be a foamed material having a thermal conductivity which is less than 0.1 W / (mK), in particular less than 0.06 W / (mK).
- the power transmission between the fastener 1 and the substrate 4 is via the load transfer regions 15, 16 made of steel or stainless steel having a compressive strength greater than 0.5 N / mm 2 .
- the second load transfer region 16 at the front end 20 of the bolt anchor 2 in the insertion direction has a spreader clip 18 which is typical for bolt anchors and is pulled over a cone 19 widening in the plug-in direction when the bolt anchor 2 is fastened.
- the expanding clip 18 is designed in such a way that an annular step 21 attached to its front end is in direct contact with the wall of the borehole 3, whereby centric tensile forces Z from the fastening element 1 in FIG transferred to the underground 4 can be.
- a part of the spreader clip 18 is enveloped by a cladding 22 with low thermal conductivity, for example made of fiber-reinforced plastic with a thermal conductivity of about 0.35 W / (mK).
- This low thermal conductivity cladding 22 may also be due to the relatively high compressive strength of fiber reinforced plastic greater than 0.5 N / mm 2
- the bolt anchor 2 can transmit large forces to the areas 7, 15, 16 necessary for the power transmission, while the insulating area 13, which is not absolutely necessary for the power transmission, is optimized with regard to the lowest possible heat transfer.
- FIG. 2 shows a further embodiment of a fastening element 1 'according to the invention.
- the fastening element 1 ' is designed as a Einbetonieranker 23 and consists of a Einbetonierhülse 24 and a threaded rod 25 as Lastangriffsstoff 7', which is fixed in a borehole 3 'by means of adhesive mass 26 in the Einbetonierhülse 24.
- the Einbetonierhülse 24 consists of a pressure-resistant insulating material 14 'having a compressive strength greater than 0.5 N / mm 2, in particular greater than 0.8N / mm 2, is, for example, of a foamed insulating material.
- compressive strengths of the insulating material can be realized which are greater than 1.0 N / mm 2 , in particular greater than 1.3 N / mm 2 .
- the concreting sleeve 24 fulfills the function of
- the concreting sleeve 24 has a collar 27, which serves as a contact surface and thermal separation layer 6 'between the attachment 5' and substrate 4 '. At the collar 27, a conical region 28 of the Einbetonierhülse 24 and thereon a cylindrical closes
- the ground 4 ' is made of concrete.
- the Einbetonierhülse 24 is introduced before the introduction of the concrete in a formwork, not shown, positioned in the formwork and surrounded by the underground 4 'forming concrete. Due to its conical shape, the concreting sleeve 24 is positively anchored in the ground 4 '. After stripping is in the Einbetonierhülse 24 a borehole 3 'with
- the borehole 3 ' is then filled with an adhesive mass 26 and the threaded rod 25 is inserted into the adhesive mass 26. It is thereby positioned with a cylindrical collar sleeve 30, so that after curing of the adhesive mass 26 tensile forces Z 'and shear forces Q' from the attachment 5 'on the threaded rod 25 and the Einbetonierhülse 24 into the ground 4' can be transmitted.
- the attachment 5 ' also has a through hole 12' through which the Threaded rod 25 with external thread 9 'is performed so that the attachment 5' with a washer 11 and a nut 10 against the collar 27 of the Einbetonierhülse 24 can be clamped. Due to the configuration of the fastening element V as a concreting sleeve 24, which is produced from a pressure-resistant insulating material 14 ', namely foam glass, relatively high forces can be transmitted into the substrate 4' with minimal heat transfer.
