Description

The invention relates to a block step according to the preamble of claim 1.

From the DE 1 961 254 U1 discloses a panel-shaped component, in particular serving as a block step, the panel massif of the component comprising a hollow chamber arrangement which is open to the outside on a suitable panel side, the panel side being averted from the visible surfaces of the panel.

It is the object of the invention to propose a block step, the production of which is simplified and which has a high level of stability. It is also the object that this block step meets the safety requirements for a structure in public space and/or also allows length adjustment without stability is significantly affected.

Starting from the features of the preamble of claim 1, this object is achieved by the characterizing features of claim 1. Advantageous and expedient developments are specified in the dependent claims.

The block step according to the invention comprises a front side wall, a rear side wall, a left side wall, a right side wall and a ceiling, with at least one cavity being formed between the front side wall, the rear side wall, the left side wall, the right side wall and the ceiling, with the cavity is accessible in particular through a bottom surface of the block step and wherein the cavity has the shape of a truncated pyramid and the front side wall, the rear side wall, the left side wall and the right side wall each have a thickness increasing in the direction of the cavity from the bottom surface in the direction of the ceiling. Such a design of the block step simplifies production, since the truncated pyramid-shaped design of the cavity causes draft angles to be formed on all side surfaces, so that a core of a production mold that keeps the cavity of the block step free can be easily removed. Furthermore, the truncated pyramid shape of the cavity also ensures stability of the block step, since the side walls, which are in pairs parallel opposite one another with their outer surfaces, have increasing thicknesses towards the ceiling, so that buckling failure of the side walls is effectively prevented.

It is also provided that the block step comprises a signaling element in an area in which the front side wall merges into the ceiling, with the signaling element extending in a longitudinal extension of the block step over its length and with the signaling element differing in material and/or colour differs from the front side wall and the ceiling. By designing the block step in this way, safety regulations applicable to public spaces can be met with it.

It is also envisaged that the signal element will be adjacent to the cavity. As a result, the signaling element is easily accessible via the cavity for the supply of electrical current or the connection of light guides or backlighting, without the need for post-processing of the block step.

Furthermore, it is also provided to arrange the signal element at a distance from the cavity such that the front side wall and/or between the signal element and the cavity the ceiling runs. As a result, the signal element is subject to less stress and can therefore be designed more cost-effectively.

It is also provided that the signal element of the block step has the shape of an elongated cuboid bar, this bar comprising a chamfer extending over the entire length of one of its longitudinal edges, with a first side surface of the bar designed as the end face of the signal element and a second side surface of the bar designed as a tread surface, wherein the front surface, the chamfer and the tread surface together form a visible surface of the rod, wherein the rod comprises a left end section, a middle section and a right end section, the middle section extending laterally beyond a longitudinal extent of the Cavity also extends, wherein the rod has a constriction extending over this central portion and wherein the constriction is formed on at least one further side surface of the rod and the visible surface is opposite. As a result, the block step can include a signal element with the usual dimensions without the stability of the block step being critically weakened by the signal element, since the signal element is adapted to the shape of the cavity in such a way that a minimum wall thickness of a concrete body of the block step is ensured in all areas. Furthermore, this ensures that the signaling element adheres to the concrete body of the block over a large area in a left-hand and a right-hand edge region of the block. In this way, it is also possible to process the block step for length adjustment in the left-hand and right-hand edge area without the risk of the signal element being separated from the concrete body as a result of the processing.

Provision is also made for the constriction to be in the form of a further chamfer. This is possible in terms of manufacturing technology with little effort.

It is also provided that the rod has a polygonal cross section or an L-shaped cross section in the area of the constriction and that the rod has a rectangular cross section in the area of the end sections. This allows both an optimal connection of the bar to the concrete body of the block step and an optimal guarantee of a sufficient distance from the cavity.

Furthermore, it is provided that the constriction extends to over half the thickness of the left side wall and over half the thickness of the right side wall. This also ensures that there is sufficient wall thickness in a first transition area, in which the front side wall, the left side wall and the top merge into one another, and in a second transition area in which the front side wall, the right side wall and the top merge into one another secured.

It is also planned to design the left side wall and/or the right side wall of the block step with its thickness measured in the longitudinal extent of the block step oversized in such a way that the block step also has the required static values when the block step is attached to the left side wall to reduce its length is shortened by up to 3 cm and/or is shortened by up to 3 cm on the right side wall. This makes it possible to work the edges of the block step without sacrificing stability. This opens up a new market, as it means that cavity blocks are now also available for projects in the Choices come up in which an adjustment of the block step in the longitudinal extent of the block step must be possible.

Furthermore, it is provided that a contact surface is formed on opposite inner surfaces of the left side wall and the right side wall in such a way that the block step can be gripped on these contact surfaces with an inside gripper, with the two contact surfaces in particular through into the left side wall and into the right side wall molded recesses are formed. Such a design of the block step means that even large-sized block steps can be easily handled mechanically on the construction site.

It is also intended to design the signaling element as a flat strip or as a strip with an L-shaped cross section in the manner of a cold plastic marking, with the signaling element being integrated flush into a concrete body of the block step. By using such signal strips, block steps can easily be designed individually in terms of color and/or day and night visibility and/or slip resistance without the concrete body having to be adjusted in its dimensions.

Finally, it is also planned to equip the block step with a second signaling element in addition to the first signaling element, with the second signaling element being designed as a flat strip in the manner of a cold plastic marking, with the second signaling element being embedded flush in the concrete body and a front side surface of the front side wall forms. As a result, the block steps can be individually customized in terms of color and/or day and night visibility and/or slip resistance design without having to adjust the dimensions of the concrete body.

Further details of the invention are described in the drawing with reference to exemplary embodiments shown schematically.

Block level 1 shown in a perspective view.

As from the synopsis of Figures 1, 2 and 3 As can be seen, the block step 1 comprises a top surface 3 which is formed by a ceiling 4 . Furthermore, the block step 1 comprises a front side face 5 which is formed by a front side wall 6 . The block step 1 also comprises a rear side surface 7 which is opposite the front side surface 5 and is formed by a rear side wall 8 . Likewise, the block step 1 comprises a left side face 9, which is formed by a left side wall 10, and a right side face 11, which is formed by a right side wall 12. Finally, the block step 1 comprises a bottom surface 13 which runs around the cavity 2 in the manner of a ring. The cavity 2 is surrounded by the top surface 3 and the walls 6 , 8 , 10 , 12 supporting the top surface 3 . The block step 1 is made of concrete B. The cavity 2 opens towards the bottom surface 13 . The deck surface 3 has a chamfer 3a with which it merges into the front side face 5. A beveled front edge VK1 of the block step 1 is formed by this chamfer 3a.

According to an embodiment variant that is not shown, provision is also made to equip the block step with a signaling element by coloring the bevel in a signal color or by applying a stripe in a signal color to the bevel. So that the presence of a block step is clearly indicated to a user.

From a comparative view of Figures 1 and 2 it can be seen that the side surfaces 5 , 7 , 9 , 11 lying on the outside of the block step 1 are opposite inner side surfaces 5 a , 7 a , 9 a , 11 a and these delimit the cavity 2 .

All four side walls 6, 8, 10, 12 have an increasing thickness D6, D8, D10, D12 from the bottom surface 13 in the direction of the ceiling 4 for increased static stabilization of the block step 1. As a result, the cavity 2 has the shape of a truncated pyramid PS1. The truncated pyramid PS1 is in all three Figures 1 to 3 indicated with dashed lines.

The block step 1 has a length L1 in the longitudinal direction, namely in the direction of the course of the bevel 3a. A width B1 and a height H1 are further external dimensions. From a comparative view of Figures 1 and 2 it can be seen that the left side wall 10 and the right side wall 12 of block step 1 with their thicknesses D10 and D12 measured in the longitudinal extent of block step 1 are oversized in such a way that block step 1 also has the required static values when block step 1 is Decreasing its length L1 at the left side wall by 10 µm is shortened to 3 cm and/or is shortened on the right side wall 12 by up to 3 cm. In the figure 1 a cut on the left side wall 10 is indicated with a section line K10 and a cut on the right side wall 12 with a section line K12. By shortening block step 1 on both sides, its length is reduced from length L1 to length L1'.

The front side wall 6 and the rear side wall 8 have the thicknesses D6, D8. For all side walls 6, 8, 1, 12, the thickness D6, D8, D10, D12 at the level of the bottom surface is indicated in the figures. As mentioned, the thicknesses D6, D8, D10, D12 steadily increase in the direction of the ceiling 4. Even after the block step 1 has been shortened, the left and right side walls 10, 12 each have thicknesses D10, D12 which correspond at least to the thicknesses D6, D8 of the front side wall 6 and the rear side wall 8.

In the Figures 4 and 5 a second variant embodiment of a block stage 101 according to the invention is shown. A cavity 102 of the block step 101 is designed as a truncated pyramid PS101, as in the first embodiment.

According to an embodiment variant that is not shown, provision is also made for the signaling element to be adjacent to the cavity.

From the figure 5 , which shows the block step 101 in a bottom view, it can be seen that in this - as in the first embodiment variant - a left side wall 110 and a right side wall 112 are oversized, so that the block step 101 can be connected on the right and/or left side by a parallel to a left Side face 109 or a right side face 111 running section can be shortened without falling below the required static values.

A contact surface 109b, 111b is formed on opposite inner surfaces 109a, 111a of the left-hand side wall 110 and the right-hand side wall 112, respectively. The block step 101 can be gripped on these contact surfaces 109b, 11b with an internal gripper (not shown). The contact surfaces 109b, 111b are each formed by a recess 116, 117 molded into the left and right side walls 110, 112.
