Supporting and reinforcing element, flat sheet, drainage system and method of manufacture

description

The invention relates to a support and reinforcing element for a box channel for line drainage according to the preamble of claim 1. The invention further relates to a flat sheet, a drainage system and a method for

Production of a support and reinforcement element.

A generic support and reinforcing element is known for example from DE 20 2016 007 589 Ul. In the known element is a stiffening part for a multi-part drainage system, which is connected as a non-positive and positive-locking bracket with the box gutter. The bracket is connected by a plug connection with the box channel. The equipment part has the function to dissipate the forces introduced into the channel, so that simple and slim components can be used. The known stiffening part is heavy and requires additional components to be anchored in the ground.

The object of the invention is to specify a support element and reinforcing element which is improved with regard to the weight and which can be anchored well in the ground, for example in a concrete bed. The invention is further based on the object to provide a flat sheet, a drainage system and a method for producing a support and reinforcing element.

According to the invention this object is achieved by a support and reinforcing element according to claim 1. With regard to the flat sheet, the object is achieved by the subject matter of claim 11, with a view to the drainage system by the subject-matter of claim 15 and with regard to the manufacturing process by the subject-matter of claim 16. Specifically, the object is achieved by a support and reinforcing element for a box channel for line drainage, which has a bottom piece and two side panels. The bottom piece and the two

Side parts form a U-profile for receiving the box gutter. The bottom piece is designed as a support for a channel bottom of the box gutter. The bottom piece and the side parts each form L-shaped bent sheet metal profiles.

The invention has several advantages.

You L-shaped bent sheet metal profiles provide improved rigidity of the support and reinforcing element. The wall thickness of the sheet metal profiles can therefore be reduced. This leads to a material and weight reduction with consistently good stability. In contrast to the prior art, the bottom piece forms a flat support, by means of which the anchoring in the floor, for example in a concrete bed, is simplified and improved. in the

In contrast to the prior art, the anchoring function is integrated into the supporting and reinforcing element, so that additional components for anchoring are dispensed with.

The L-shaped bent sheet metal profiles can be made of the same material as the box gutter and have the same wall thickness as the box gutter. This has the advantage that the support and reinforcing element serves as a filling part when cutting the box channel from a flat sheet. As a result, a better utilization of the flat sheets in the Kastenrinnenherstellung is possible.

The support and reinforcement element is particularly well suited for use in connection with hygiene box gutter, which are used for example in commercial kitchens and in industrial food production. The

Hygiene standards, for example in kitchens, are very high. So-called hygiene box gutters are special for this due to their design

Scope of application is conceived and characterized among other things by large radii, large gradients in the longitudinal and transverse direction and a cavity filling. Hygiene box gutters are usually made of stainless steel.

It is also possible that the support and reinforcing element according to the invention is used for sanitary box gutters, which are mainly used in shower facilities for Example in swimming pools or spa and wellness areas are used.

Preferred embodiments of the invention are specified in the subclaims.

Thus, the bottom piece and the side parts may be integrally formed. The support and reinforcement element can be easily manufactured without requiring welding. The production takes place, for example, by punching and folding a flat sheet.

Preferably, the sheet metal profiles have a wall thickness of 1 mm to 2 mm, in particular about 1.5 mm. This will make material without significant

Saved stiffness. In addition, the wall thicknesses of

Box gutters also in this area.

In a particularly preferred embodiment, the sheet metal profiles each have two legs, wherein the first leg are arranged in use substantially perpendicular to the box channel and a second leg in use substantially parallel to the box channel. This embodiment has the advantage of a particularly stable construction. The second leg forms a broad support for the ground anchoring.

Further preferably, the first leg of the bottom piece forms a

Support leg for the channel bottom, the free top edge of a

Compensation recess for the channel bottom has. As a result, a solid, positive support is created during assembly, since manufacturing or

Mounting tolerances are compensated.

The compensation recess can be arranged at the lowest point of the free upper edge. This position is optimal for V-shaped inclined channel bottoms.

The second leg of the bottom piece and / or the side parts may have a

Form anchoring leg having holding openings. The holding openings improve the anchoring of the second leg in the concrete bed, or generally on the ground.

The side part may have a fold-out anchoring part, the free end of the bottom part is further removed than the folding axis to the the

Anchoring part works. The fold-out anchoring part allows additional anchoring of the support and reinforcement element near the bottom. For this purpose, the free end of the bottom part is further removed than the folding axis, so that the anchoring part can be folded down.

Preferably, the bottom part has at least two adjustment openings, each receiving a height adjustment. This embodiment is

intended, for example, as a heavy-duty version.

In each case a mounting plate for a height adjustment can be attached to both sides parts, in particular welded. The mounting plate extends substantially perpendicular to the respective side part. This is an alternative solution to the two adjustment holes in the bottom part.

In the context of the invention, a flat sheet for the production of a support and reinforcing element according to the invention is further disclosed and claimed. The flat sheet is an intermediate that is self-negotiable and as such has a market value. The flat plate has a longitudinal axis and a transverse axis perpendicular thereto, which is shorter than the longitudinal axis. The flat sheet has at least one longitudinal fold for forming the L-shaped sheet metal profiles for the bottom piece and the side parts. The longitudinal fold extends along the longitudinal axis. The flat plate has transverse folds for forming the U-profile, which extend along the transverse axis of the flat plate. The flat sheet also has joining recesses which adjoin the transverse folds, the joining recesses each having two joint edges, which in the bent state form the transition from the bottom piece to the respective one

Form side part.

The longitudinal fold can be continuous or interrupted. When the longitudinal fold is interrupted, the Längsfalzabschnitte the bottom piece or the

Assigned to side parts. The longitudinal fold has the advantage that the L-shape of the Sheet metal profiles can be formed by bending quickly and safely. The transverse folds and joining recesses act together when the side parts are bent upwards and allow the formation of the U-shape of the support and support in a simple manner

Reinforcing element. The Fügeeausnehmungen are auxiliary elements to the joining of the side parts and the bottom piece by bending to

facilitate. When bending the side parts, the joining recesses are reduced. In the final state, i. If the support and reinforcing element forms a U-profile, the joining recesses are completely or almost completely disappeared. The joining edges of the respective joining recesses are arranged directly on one another or at least with a slight gap on one another.

The joint edges do not necessarily have to touch each other. The joining edges form the transition from the bottom piece to the respective side part in the bent state.

In a preferred embodiment of the flat sheet are the

Joining recesses each formed substantially triangular. The tip of the respective joining recesses follows the corresponding transverse fold. This flat sheet can be, for example, produce by punching.

Preferably, the angle at the tip between the joining edges of a

Joining recess greater than 90 °. This has the advantage that manufacturing or assembly tolerances of the box channel can be compensated by the fact that the two side parts can be arranged in a certain angular range by 90 ° relative to the bottom piece, so close to the box channel

to rest. In other words, the angle between the side parts and the bottom piece may each be slightly more or less than 90 °.

In a further preferred embodiment, a first joining edge has a profile projection, in particular a pin-like profile projection. The associated second joining edge has a complementary profile recess, wherein the profile projection and the profile recess engage in the bent state. In the region of the profile projection, for example, a welding point can be attached in order to fix the side parts and the bottom piece. In addition, the profile projection and the profile recess have a guiding function when bending up the side parts. In the context of the invention, a drainage system with at least one box channel for line drainage and at least one

claimed support and reinforcing element according to the invention. In the inventive method for producing a support and

Reinforcing element, a flat sheet is profiled by punching and bent along the at least one Längsfalzes and along the Querfalze, so that the support and reinforcing element according to the invention is obtained.

Embodiment and

Fig. 5 shows a detail of a support and reinforcing element according to another embodiment of the invention with a fold-out anchoring part.

In Fig. 1, an example of a supporting and reinforcing element is shown, which is used for a box channel or generally for a gutter. The support and reinforcing element surrounds in the assembled state, the box channel (not shown) and supports it from the side and down from, so that in the Box gutter induced forces are derived by the support and reinforcing element in the ground. In addition, the shape of the box gutter is stabilized by the reinforcement of the side walls of the box gutter.

The support and reinforcing element has for this purpose a bottom piece 10 and two side parts 11, which together form a U-profile 13. In use, the box channel is arranged in the U-profile 13 in such a way that the channel bottom rests on the bottom piece 10.

To improve the rigidity of the bottom piece 10 and the side parts 11 are each formed as L-shaped bent sheet metal profiles 14. The sheet metal profiles 14 each have two legs 15, 16, 17, 18, which form the L-shape. The first leg 15, 17 is arranged in use substantially perpendicular to the box channel. The first leg 15, 17 of the sheet metal profiles 14 thus forms the frame into which the box channel is inserted and which determines the inner contour of the U-profile. The first legs 15, 17 of the bottom piece and the two side pieces 11 are arranged substantially in a plane which extends substantially vertically in the mounted state. The second legs 16, 18 of the sheet metal profiles 14 are arranged in use substantially parallel to the box channel. Specifically, the second leg 16 of the bottom piece 10 in

Almost parallel to the channel bottom arranged (neglecting the inclination of the gutter bottom). The two second legs 18 of the side parts 11 are arranged substantially parallel to the side walls of the box channel, whereby it also applies here that a certain deviation from the parallelism is possible depending on the angle of inclination of the side walls 11.

1, the first leg 15 of the bottom piece forms a support leg for the channel bottom. For this purpose, the first leg 15 has a free upper edge 19, which serves as a support for the channel bottom in the assembled state. The free upper edge 19 is adapted to the shape of the channel bottom and extends, as seen in Fig. 1, substantially V-shaped. At the lowest point of the free upper edge 19, a compensation recess 20 is formed for the channel bottom. The compensation recess 20 is a circular arc section

executed. Other geometry is possible. The second leg 17 of the bottom piece 10, ie the leg 17 substantially parallel to the channel bottom serves as anchoring leg and has a plurality of retaining openings 21. In use, the second leg 17 is anchored in the concrete bed of the floor, wherein the concrete passes through the holding openings 21 and thus a firm connection of the support and

Reinforcement element with the ground creates. The holding openings 21 are formed as slots. Other geometry is possible. As can be seen in FIG. 1, the first leg 15 of the bottom piece 10 has further holding openings 21. The further holding openings 21 can likewise dip into the concrete and thus also serve as anchors. The holding openings 21 have the further advantage that the weight of the supporting and reinforcing element is reduced.

A modification of the supporting and reinforcing element according to FIG. 1 is shown in FIG. 5. There it can be seen that the side part 11 is a fold-out

Anchoring part 22 has. The anchoring part 22 is arranged so that it is arranged in the unfolded state near the bottom. For this purpose, the free end of the fold-out anchoring part 22 is further away from the bottom part 10 than the folding axis about which the anchoring part 22 can be folded, as shown in FIG. In use, the fold-out anchor member 22 is folded down so far that it can dip into the concrete bed. For better anchoring of the anchoring part 22, this has a holding openings 21 similar to the holding openings 21 of the bottom piece 10.

In Fig. 5 it can be seen that the bottom piece 10 has an adjustment openings 23 through which a height adjustment means can be connected to the bottom piece 10. In the example of FIG. 1, the adjustment openings 23 is formed as a nut, which is connected to the bottom piece 10. Through the thread of the nut, a corresponding threaded bolt can be screwed. An alternative height adjustment is given in the embodiment of FIG. 2 by the mounting plate 25, which is attached to the outside of the side parts 11 respectively, in particular welded.

The starting example according to FIG. 2 differs from the exemplary embodiment according to FIG. 1 essentially by the height of the side parts 11, which in the example according to FIG. 2 is lower than in the example according to FIG. Besides, in the first one Leg 15 of the bottom piece 10 no openings provided. The first leg 15 is closed.

The flat sheet of FIG. 4 forms an intermediate product in the production of the support and reinforcing element, wherein in FIG. 4, three sub-steps starting from the punched-flat plate to the finished curved support and

Reinforcing element are shown.

Before punching, the flat sheet is substantially rectangular, with the

Longitudinal axis of the flat plate of the long side and the transverse axis of the short side of the rectangle corresponds. The flat sheet has a longitudinal fold 26 which extends along the longitudinal axis. The longitudinal fold 26 divides the flat sheet so that after bending in each case the first and second legs of the

Sheet metal profiles 14 arise.

The flat plate has transverse folds 27, which serve to be able to fold the side parts 11 upwards in a targeted manner. For this purpose, the transverse folds 27 each extend along the transverse axis. In the example according to FIGS. 1 to 5, the transverse folds 27 are interrupted by a longitudinal opening which is aligned with the transverse folds 27. In other words, the transverse folds 27 2 each form two

Hinge webs connecting the side panels 11 and the bottom piece 10.

As can be seen in detail in FIG. 3 (left illustration) or in FIG. 4, first step, the flat sheet has two joining recesses 28. The joining recesses 28 are assigned to the transverse folds 27 and serve to be able to connect the side parts 11 to the bottom piece 10 during bending. These are the

Joining recesses 28 formed triangular. The joining recesses 28 are bounded by two joining edges 29, 30 in each case. The joining edges 29, 30 converge in the region of the transverse folds 27, so that the tip 31 of the respective triangular joining recess 28 adjoins the corresponding transverse fold 27. The angle between the joint edges, which is the top 31 of the

Fügeausnehmung 28 determines is greater than 90 °, the more a certain

Tolerance compensation for the box gutter created.

As can be clearly seen in FIG. 3, the first joining edge 29 has a

Profile projection 32 in the form of a pin, which is substantially perpendicular extends to the joining edge 29. The associated second joining edge 30 forms a complementary profile recess 33, which corresponds to the pin shape in Fig. 3.

Other geometry in is possible.

The production of the support and reinforcing element is based on FIG. 4

described, with the two intermediate steps 2, 3 are shown in Fig. 3 in detail.

In the first step, the L-shaped sheet-metal profiles 14 are produced. For this purpose, the legs 15, 16, 17, 18 bent in an L-shape. This can be done by a single step. In the second step, the L-shaped sheet metal profiles 14 are bent over to the U-profile. For this purpose, the two side parts 11 are bent at the transverse folds 27 upwards. The starting position according to step 2 is shown in detail in the left-hand illustration according to FIG. 3. The final state, as shown in the third step of FIG. 4, is shown in detail in the right-hand illustration of FIG. It is easy to see that the profile projection 32 engages in the complementary profile recess 33. The joining edges 29, 30 are directly adjacent to each other or are arranged with a slight gap to each other. The joining recess 28 shown in the left-hand illustration according to FIG. 3 or in the second step according to FIG. 4 has disappeared, so that a transition from the bottom piece 10 to the corresponding side part 11 in the region of the joining edges 29, 30 results.
