Description

Retainer pipe

The present invention relates to a fixture pipe with the features of the preamble of claim 1. The invention further relates to two fastening arrangements with such fixture pipes according to claims 11 and 12.

Fixer pipes are usually arranged to sink flush in a floor or wall made of concrete, and serve to fasten objects such as machinery by means of, for example, hammer screws. "Settlement flush" means that the anchor pipe is embedded in the concrete and one side of the anchor pipe is flush with the surface of, for example, the concrete. During the manufacture of floors or the like, concrete is cast around the fixture pipes on three sides. The fixture pipe usually has a C-shaped contour pipe, that is, a square pipe contour or a rectangular pipe contour with a continuous longitudinal groove in the lateral center of one side (which is also referred to as the "upper side" herein).

European patent application EP 3 438 361 A1 discloses a fixer pipe with a C-shaped profile pipe. Since the C-shaped profile pipe is fixed in concrete, a bolt-like bolt with disc-shaped feet in the longitudinal center plane of the C-shaped profile pipe The holders protrude from the lower side positioned relative to the groove of the C-shaped contour pipe. The holders are cast into the concrete during the casting of the holder pipe and the holder pipe is fixed in the concrete to prevent the holder pipe from being perpendicular to the concrete. The surface is pulled out of the concrete. The anchor pipe is arranged parallel to the edge of the concrete body and close to the edge of the concrete body. If excessive lateral force is applied to the anchor pipe in the direction parallel to the concrete surface and in the direction of the edge, the anchor pipe can be separated from the concrete body due to its arrangement close to the edge, and a fracture cone or usually is left in the concrete body. Fracture site. For structural reasons, anchor pipes arranged close to the edge of the concrete body usually must be "tieback-anchoring". In order to overcome the lateral force that is transverse to the C-shaped contour pipe and parallel to the surface of the concrete, the known fixture pipe has a rod-shaped fixture, which protrudes from the lower side positioned opposite to the groove of the C-shaped contour pipe, and is perpendicular On the central plane where the bolt-like holder is located. During casting, the rod holder is cast parallel to the surface of the concrete, and settles under the surface of the concrete to the height of the C-shaped contour pipe. The rod holder absorbs the lateral force acting on the holder pipe, and prevents the holder pipe from being able to escape from the concrete body along the edge direction of the concrete body. The disadvantage of the prior art lanyard fixation is that this kind of lanyard fixation cannot be modified to the concrete body, but must be cast during the manufacture of the concrete body.

The problem of the present invention is to propose a more flexible lanyard fixation. On the one hand, it provides the possibility of retrofitting the anchor pipe’s lanyard fixation to concrete or into concrete, and on the other hand allows pouring in concrete In the meantime, the anchor pipe is fixed by a predetermined lanyard.

According to the present invention, the aforementioned problems are solved by the features of claims 1, 11 and 12. The holder pipe according to the present invention has a C-shaped contour pipe with a groove in the first side of the C-shaped contour pipe, the holder pipe is intended to be flush with the surface of the concrete except for the first side of the C-shaped contour pipe , The C-shaped contour pipe will be cast in a way that is embedded in the concrete. The groove is in particular in the longitudinal direction of the C-shaped profile pipe, especially in the transverse center of the C-shaped profile pipe, or rather a continuous groove on its first side. One or more fixing elements protrude from the second side, the second side is positioned opposite to the first side, and the fixing elements fix the cast-in C-shaped contour pipe in the concrete.

In addition, the holder pipe according to the present invention has at least one surface holder for the cable fixing of the C-shaped contour pipe, the surface holder is supported on the first side of the C-shaped contour pipe and is free from (ie opposite to) The third side of the C-shaped profile pipe adjacent to the first side protrudes. The part of the surface fixture protruding from the C-shaped contour pipe in particular protrudes from the C-shaped contour pipe at a right angle and is configured as a strip. The strip is especially a flat steel strip or thin steel plate that has been customized or stamped. The strip has a width in particular less than 60 mm, preferably between 30 mm and 50 mm. "Width" should be understood as the size of the strip in the longitudinal direction of the C-shaped profile pipe. In detail, the length of the strip is an integer multiple of the width of the strip. "Length" should be understood as the distance between the strip and the pipe of the holder. The length of the strip preferably corresponds to at least three times and especially at least five times the width of the strip. However, depending on the structural environment and intended use of the surface fixture, the length can also correspond to five to ten or twenty times the width. Even longer strips are possible. In detail, in the case of a longer anchor pipe, a plurality of surface anchors, especially equidistant from each other, are arranged on the anchor pipe, resulting in a uniform lanyard fixation over the entire length of the anchor pipe .

The surface holder does not need to be directly connected to the third side or directly arranged on the third side, but only needs to protrude above or outside the other surface. The surface holder can be supported directly or indirectly, for example, by means of an intermediate piece for high equalization. Preferably, the surface holder can be connected to the C-shaped profile pipe on the first side. In detail, the surface holder is operatively connected to the groove of the C-shaped contour pipe, and can be additionally connected to the first side of the C-shaped contour pipe. However, the surface holder need not necessarily engage the groove. The surface holder can for example simply be placed on the first side of a C-shaped profile pipe that is flush with the surface and in particular only partially covers the groove, and is thereby fastened (especially by welding) to the C-shaped profile pipe. In at least some cross-sections, the surface fixture can be configured as a thin sheet metal strip with cutouts whose dimensions are substantially complementary to the dimensions of the grooves of the C-shaped profile pipe. In detail, a thin sheet metal strip with a cut is welded to the first side of the C-shaped profile pipe, for example by riveting or fastened to the first side in some other way, so that the cut at most partially covers the groove. In detail, the width of the cut is complementary to the lateral width of the groove of the C-shaped profile pipe.

The surface fixture, or more precisely the strip of surface fixture, is arranged on the C-shaped contour pipe so that when the C-shaped contour pipe has been cast as expected, the surface fixture protrudes to one side of the C-shaped contour pipe and Supported on the surface of the concrete or flush with the surface of the concrete. The surface holder has a fixing member at a distance from the C-shaped profile pipe, especially at one end of the strip. The fixing member is usually a method or device for fastening a surface fixer to concrete. For example, it can be a hole in a strip, by means of which the surface fixator can be aided by a fastening member (for example, a bolt fixator, a concrete screw, a fixing rod chemically fastened in the concrete, or the like Person) and firm to concrete. Another possibility is that the surface fixture is fixed, for example by bonding to concrete. In this case, if the adhesive extends to the C-shaped contour pipe, the center point of the joint surface is spaced from the C-shaped contour pipe. The fixing element is an adhesive under that condition. However, the surface fixture can also be firmly fixed in a building element made of concrete, especially cast into the building element to a depth that makes it flush with the surface of the concrete (ie, the building element). The surface holder is therefore especially flush with the surface. Here the C-shaped profile pipe is fixed in the concrete of a predetermined type, the surface fixer is therefore at least partly joined to the concrete and the fixing element is especially likewise at least partly cast into the concrete. In that case, the fixing members are especially holes, bolts, pigtail anchors or the like. The advantage of a predetermined type of fixation is that substantially the entire surface of the concrete can be used, and the surface will not be hindered by the surface fixer. Under the condition of retrofitting and fixing, the surface fixer is supported on the C-shaped contour pipe, and therefore creates a potentially tricky protrusion on the originally flat surface of the concrete.

The present invention first has the advantage that the cast C-shaped contour pipe of the fixture pipe can then be tightened against the lateral force load, that is, it can be fixed by a lanyard. Under the condition that the C-shaped contour pipe in the concrete is arranged close to the edge, it may be advantageous or even necessary if the C-shaped contour pipe at the edge of the concrete is at risk of lateral separation of the concrete or if such detachment has already occurred. . It is also possible to prevent the concrete from detaching by the predetermined fixing of the C-shaped contour pipe. In this case, as mentioned above, the entire surface of the concrete can be used.

According to the present invention, the surface holder, or more precisely a strip, can be laterally from the C-shaped contour pipe or protrude from its third side on a plane that is in line with the first of the C-shaped contour pipe with grooves. The side is flush, or the surface holder can pass through a plane that is flush with the first side of the C-shaped profile pipe. The third side is the side of the C-shaped profile pipe adjacent to the first side with the groove. In the first situation, once the C-shaped contour pipe has been cast as expected, the surface fixture is supported on the surface of the concrete. In the second situation, the surface fixture penetrates the concrete from the side of the C-shaped contour pipe. The second condition is intended for the condition where the surface fixture is attached to the C-shaped contour pipe from the beginning, so that during the casting of the C-shaped contour pipe, the surface fixture is also cast with the C-shaped contour pipe and does not need to be subsequently lowered into the concrete . As mentioned earlier, this configuration has the following advantages: the surface fixture is not supported on the concrete over its entire length, but it is partially or completely located in the concrete.

The fastening of the surface fixture to the C-shaped contour pipe can be achieved, for example, by installing the surface fixture in the groove of the C-shaped contour pipe. The installation only needs to be resistant to tension in the direction in which the surface fixture protrudes from the C-shaped contour pipe, that is, the lateral force of the C-shaped contour pipe can be transmitted to the surface fixture as tension. Mounting the surface holder in the groove of the C-shaped contour pipe is a simple, fast and economical way to connect the surface holder to the C-shaped contour pipe.

The surface fixture may have a single hook for connecting to the C-shaped contour pipe, the single hook being engaged around the first edge of the groove of the C-shaped contour pipe, so that it transmits the lateral force of the C-shaped contour pipe as tension to the surface fixing Device. The surface holder can also have a double hook. Once the double hook (ie, the surface holder) has been connected to the C-shaped contour pipe, the double hook engages around the first edge of the groove of the C-shaped contour pipe and is opposite to the groove of the C-shaped contour pipe. The second edge of the position is engaged underneath, so that the double hook cannot be easily lifted out of the C-shaped contour pipe.

In order to connect the surface fixture to the C-shaped contour pipe, another specific example of the present invention provides a fastening device fastened to the C-shaped contour pipe or in the C-shaped contour pipe. The shank protruding from the groove in the first side. The fastening device can be, for example, a hammer head screw or a sliding nut with a screw-in threaded bolt. The surface holder is fastened to the handle of the fastening device, which protrudes from the groove of the C-shaped contour pipe.

In another advantageous embodiment of the present invention, the surface fixture has a surface structure on a side remote from the first side, in particular serrations. The fastening device (for example, the fastening device as described in the previous paragraph) can thereby be fixed by interlocking and/or frictional engagement to prevent displacement along the groove of the C-shaped contour pipe.

A specific example of the present invention provides that the surface holder connects the C-shaped contour pipe to the second C-shaped contour pipe, which is configured to be spaced apart from the first C-shaped contour pipe. The surface fixer transfers the load from one C-shaped contour pipe to another C-shaped contour pipe spaced apart from it.

A specific example of the present invention provides that the surface fixture includes or consists of a pseudoplastically stretched shape memory alloy. Shape memory alloys are metal alloys that change their shape through the phase change of their crystal structure (especially between Asada iron and austenitic iron). Phase change and shape change occur when the transition temperature is reached or exceeded. Shape memory alloys must undergo pseudoplastic deformation in advance, which is usually but not necessarily achieved by mechanical deformation, which can then be fully or partially reversed by heating to a transformation temperature or above. A shape memory alloy with a two-way effect is also known, which deforms at high temperature and fully or partially returns to its original shape at low temperature. In this specific example of the present invention, once the surface fixture has been secured to or in the concrete, by heating the surface fixture to or above the transformation temperature of the shape memory alloy, tensile stress can be generated in the surface fixture , That is, the surface fixture is prestressed.

An embodiment of the present invention provides elastic and/or plastically deformable strips outside the fourth side of the C-shaped profile pipe, the fourth side being adjacent to the first side and positioned relative to the third side. The first side has a groove, and the surface fixer protrudes from the adjacent third side. The deformable strip is therefore positioned externally on the C-shaped profile pipe, opposite to the side from which the surface holder protrudes. Preferably, the deformable strip occupies the entire area of the fourth side of the C-shaped contour pipe. The deformable strip allows the C-shaped contour pipe in the concrete to be slightly displaced in the direction transverse to the C-shaped contour pipe in the direction opposite to the direction in which the surface holder protrudes from the C-shaped contour pipe. The slight displacement caused by the compression of the strips, in particular, enables the single and double hooks to be firmly in the groove of the C-shaped contour pipe under tension before the C-shaped contour pipe contacts the concrete. In other words, before the C-shaped contour pipe actually contacts the concrete, a certain amount of gap between the single and double hooks and the C-shaped contour pipe may be compensated.

In order to explain the fastening arrangement according to the present invention, refer to the explanation given above of the fixture pipe according to the present invention.

In the fastening arrangement for the anchor pipe fixing of the anchor pipe according to the present invention, the C-shaped contour pipe of the anchor pipe is fixedly settled in the construction element made of concrete so that it has the first side of the groove and the construction The surface of the component is flush. In addition, the surface holder is connected to the C-shaped contour pipe on the first side and protrudes from the C-shaped contour pipe on a third side adjacent to the first side. The surface fixer, or more precisely, the strip is supported on the surface of the building element and secured to the building element at a distance from the C-shaped profile pipe or penetrates the building element laterally from the C-shaped profile pipe.

In detail, in this fastening configuration, the C-shaped contour pipe is arranged close to the edge of the building element, that is, close to the edge and especially parallel to the edge of the building element. "Close" here means that the distance between the C-shaped contour pipe and the edge corresponds to twice the length of the C-shaped contour pipe to the maximum extent, and in particular, the distance is smaller than the length of the contour pipe. The surface fixture, or more accurately the strip of surface fixture, extends away from the edge of the building element at an angle (especially a right angle) relative to the C-shaped pipe. The strips of the surface fixer are therefore far away from the edges. The strap is particularly firm to the surface of the building element or fixed in the building element at the end of the strap away from the C-shaped profile pipe, resulting in a stable lanyard fixation of the fixture pipe. With the aid of the fastening arrangement according to the invention, the anchor pipe can thus be cast firmly into the building element close to its edge without any risk of detaching from the building element when it is subjected to a load.

As mentioned above, the C-shaped contour pipe can also be fixed in concrete building elements, especially cast into building elements, and sink to a depth that makes the surface fixer flush with the surface of the building element.

The features and feature combinations, configurations, and specific examples of the present invention mentioned above in the description and the features and feature combinations mentioned in the description of the drawings and/or shown in the drawings below can not only be used in every situation They are used in specific combinations defined or shown, and can basically be used in any other combination or individually. The configuration of the invention that does not have all the features of the attached claims is possible. The individual features of the requested item may also be replaced by other disclosed features or combinations of features. The configuration of the present invention may not have all the features of the specific example, but in principle, it has the characteristic features of the illustrative specific example that is combined with one, some or all of the features of one or more other illustrative specific examples as appropriate. Any part of.

The fixture pipe 1 according to the present invention shown in Fig. 1 has a C-shaped profile pipe 2 with a rectangular hollow profile with a continuous longitudinal groove 3 in the first side 4, the first side One side can also be referred to as the upper side of the C-shaped profile pipe 2.

The holder pipe 1 or its C-shaped contour pipe 2 is intended for casting into a building element 5, such as a concrete floor, so that as can be seen in Fig. 1, except for the first side 4 of the C-shaped contour pipe 2 with the groove 3 and the building The surface of the element 5 is flush, and the C-shaped contour pipe 2 sinks into the building element 5. Only some of the edges of the building elements 5 are shown in the drawings, and the building elements are shown as transparent so that the fixture pipe 1 is visible.

The fixing elements 7 protrude from the second side 6 positioned opposite to the first side 4, and this second side can also be referred to as the lower side of the C-shaped profile pipe 2. The fixing elements 7 are fastened (for example, welded) to C The second side 6 of the contoured pipe 2. In an illustrative specific example, the fixing element 7 is a bolt having a flange-like foot 8 at its end away from the C-shaped contour pipe 2. The fixing element 7 is embedded in the concrete of the building element 5 and holds the C-shaped contour pipe 2 to prevent it from being pulled out from the building element 5 perpendicular to its surface. In an illustrative specific example, the fixing element 7 is arranged in the longitudinal center plane of the C-shaped contour pipe 2. The fixing element 7 can, for example, protrude from the second side 6 of the C-shaped contour pipe 2 and also extend to the building element 5 at a V-shaped angle to each other as seen in the longitudinal direction of the C-shaped contour pipe 2 (not shown in the figure) middle.

In the exemplary embodiment, a strip-shaped surface holder 9 is installed in the groove 3 of the C-shaped contour pipe 2. The surface holder is supported on the first side 4 of the C-shaped contour pipe 2 and is formed as a strip The form protrudes on the third side 10 of the C-shaped contour pipe 2 or from the third side 10 of the C-shaped contour pipe 2, which is adjacent to the first side 4. The surface fixer 9 is supported on the surface of the building element 5. At one end, the surface fixture 9 has a single hook 11 that engages around the first edge 12 of the groove 3 of the C-shaped contour pipe 2 and connects the surface fixture 9 to the C-shaped contour pipe in a tension-resistant manner. 2. "Tension resistance" means that the single hook 11 of the surface anchor 9 installed in the groove 3 of the C-shaped contour pipe 2 transmits the lateral force acting laterally with respect to the C-shaped contour pipe 2 to the surface anchor 9 as a surface fixation The tension acting in the longitudinal direction of the device 9.

Close to the end of the C-shaped contour pipe 2 far from the holder pipe 1 according to the present invention and at a distance from the C-shaped contour pipe 2 in any situation, the surface holder 9 has a hole at one end of the strip, the hole In this text, it is generally referred to as the fixing member 13 of the surface fixing device 9. By means of the holes in the strip forming the fixing member 13, the surface fixer 9 can be secured to the building element 5 at a distance from the C-shaped contour pipe 2 and is therefore used for the cable fixing of the C-shaped contour pipe 2. For that purpose, for example, a screw can be screwed through the fixing member 13 (formed as a hole) of the surface fixer 9 into an expandable fastening plug (not shown in the figure) that has been expanded and fixed in the building element 5 .

The surface fixer 9 can also be secured by bonding to the surface of the building element 5, for example. In that case, the adhesive forms a fixing member that connects the surface holder 9 to the building element 5 at a distance from the C-shaped contour pipe 2, even though the adhesive has been applied to the surface holder 9 as far as the C-shaped contour pipe 2 .

On the fourth side, the C-shaped profile pipe 2 has a deformable strip 15 that completely or almost completely covers the fourth side 14 of the C-shaped profile pipe 2 on the outside. In the illustrative embodiment, the strap 15 is composed of an elastic solid foam material. The fourth side 14 of the C-shaped profile pipe 2 abuts its first side 4 with the groove 3 and the relatively positioned second side 6 from which the fixing element 7 protrudes. The fourth side 14 of the C-shaped profile pipe 2 is positioned opposite to the third side 10, and the surface holder 9 is on the third side or protrudes from the third side. If the C-shaped contour pipe 2 is subjected to a lateral load, that is, longitudinally relative to the surface holder 9 and away from the surface holder, the deformable strip 15 allows the C-shaped contour pipe 2 in the building element 5 to be relative to the C-shaped contour pipe 2 Move laterally, parallel to the surface of the building element 5 and away from the surface holder 9 slightly. This avoids the early detachment of the concrete of the building element 5 when the C-shaped profile pipe 2 is subjected to such lateral stress.

The C-shaped contour pipe 2 of the holder pipe 1 according to the present invention preferably has a plurality of surface holders 9 which are installed in the groove 3 of the C-shaped contour pipe 2 and are opposite to the C-shaped contour pipe 2 It is secured laterally to the building element 5, parallel to each other and spaced apart from each other in the longitudinal direction of the C-shaped profile pipe 2. The surface fixer 9 fastens the C-shaped contour pipe 2 against the lateral force and prevents the concrete from detaching, especially under the condition that the C-shaped contour pipe 2 in the building element 5 is arranged close to the edge. The surface fixer 9 protrudes from the C-shaped contour pipe 2 on the side opposite to the edge 16 of the building element 5 close to the C-shaped contour pipe 2.

As shown by the dashed line in Figure 1, the surface fixture 9 can also be tilted so that it is laterally adjacent to the C-shaped contour pipe 2 and penetrates the concrete of the building element 5 and fastens the C-shaped contour pipe 2 against the lateral force. Architectural element 5. In that situation, the surface holder 9 is laterally adjacent to the C-shaped contour pipe 2 penetrating the surface of the building element 5, and the surface of the building element 5 is flush with the first side 4 of the C-shaped contour pipe 2, and is thus formed with C The first side 4 of the contour pipe 2 is flush with the plane.

In FIG. 2, the surface holder 9 has a double hook 17 instead of a single hook 11 at its end. Like the single hook 11, the double hook 17 engages around the first edge 12 of the groove 3 of the C-shaped contour pipe 2, and in addition engages below the second groove edge 18 positioned opposite to the first edge 12, so that the double hook 17 cannot come from the groove 3 Pull out and the surface holder 9 cannot be lifted from the first side 4 of the C-shaped contour pipe 2.

In the exemplary embodiment of the present invention shown in FIG. 3, a hammer head screw 19 connects the surface fixture 9 to the C-shaped profile pipe 2. The hammer head screw 19 (usually can also be regarded as the fastening device 20) is installed in the C-shaped contour pipe 2 by its hammer head 21 so that its shank protrudes from the groove 3 of the C-shaped contour pipe 2 to the first side 4 superior. Instead of the hooks 11 and 17, the surface fixer 9 in this illustrative embodiment of the present invention has a hole through which the shank 22 of the hammer screw 22 forming the fastening device 20 extends so that the surface fixer 9 is installed On the groove 3 of the C-shaped contour pipe 2 and connected to the C-shaped contour pipe 2 in a different manner. Components (not shown in the figure), for example, a machine frame, can be attached to the handle 22 of the hammer head screw 19 forming the fastening device 20, which protrudes from the C-shaped contour pipe 2 and at the same time protrudes from the building element 5 .

In the exemplary embodiment of the present invention shown in FIG. 4, two C-shaped contour pipes 2 are arranged in a sinking manner in the building element 5. The C-shaped contour pipes are spaced apart from each other and parallel to each other, wherein the first side 4 thereof There is a groove 3 flush with the surface of the building element 5. A plurality of surface fixers 9 arranged transversely and parallel to each other with respect to the C-shaped contour pipe 2 connect the two C-shaped contour pipes 2, as a result, the C-shaped contour pipe 2 arranged close to the edge of the building element 5 can be fastened to The C-shaped contour pipe 2 further away from the edge of the building element 5. Figure 4 shows only one surface fixator 9.

In the illustrative specific example shown in FIG. 5, the surface fixer 9 is formed by two strips each having a fixing member 13 and a thin metal strip 25 having a cutout 26. The thin metal strip 25 is welded to the first side 4 of the C-shaped contour pipe 2 so that the cut 26 is oriented parallel to the groove 3 and therefore does not confuse the groove 3 of the C-shaped contour pipe 2. The basic difference between the illustrative specific example of FIG. 5 and the foregoing illustrative specific example is that it is not the first side 4 of the C-shaped contour duct 2 which is flush with the surface of the building element 5, but is flush with the surface of the component 5. Flat surface fixator 9. Therefore, the entire surface area of the component 5 can be used because the surface holder 9 does not produce a protruding area. The C-shaped contour pipe 2 is cast into the building element 5 together with the surface fixer 9.

The surface fixer 9 has a surface structure 23 in the form of saw teeth 24. Therefore, for example, a hammer head screw fastened in the groove by means of a serrated washer can be fastened to prevent sliding in the longitudinal direction of the pipe (ie, along the groove 3 (not shown in the figure)). The serrated washer is engaged in the serrated 24.

The surface holder 9 can in principle be composed of any desired material, for example a metal strip. The surface fixer 9 may also be made of plastic, especially made of fiber-reinforced plastic. For example, the surface fixer 9 may be composed of or include a prepreg. The prepreg has fibers embedded in synthetic resin, which may harden the synthetic resin for bonding to the surface of the building element 5 (not shown in the figure).

The illustrative specific example of the present invention provides that the surface fixture 9 is composed of or at least contains a pseudo-plastic tensile shape memory alloy. The surface fixture 9 becomes shorter when it is heated to or above the transformation temperature of the shape memory alloy. This makes it possible to generate tensile stresses in the surface fixture 9 so that the surface of the building element 5 that is far away from the edge of the building element 5 close to the C-shaped profile pipe 2 is towards the C-shaped profile transversely with respect to the C-shaped profile pipe 2 and parallel Pipe 2 is pre-stressed.

The fixture pipe 1 embedded in the construction element 5 and its C-shaped contour pipe 2, the fixing element 7 protruding from its lower side and also embedded in the construction element 5, and the fixing element 7 firmly to the construction element 5 or firmly in the construction element 5 The surface holder 9 forms a fastening arrangement according to the invention.
