Description

The invention relates to a mobile safety barrier according to a preamble of claim 1. The safety barrier of this type has quadrangle-shaped panels in side view, adjacent to each other at ends and coming into contact with each other, directly or indirectly. The ends of safety barrier has beds at the top and bottom flat bars or profiles at the bottom. In addition, the safety barrier is provided with at least one connecting element which has at the bottom a shape that corresponds to a shape of panel beds positioned at a top part of the panels and together with the connecting means serves for connecting at the top the adjoining panels by means of the connecting element. For connecting the adjoining panels at the bottom serve bottom connecting elements and a bottom strip corresponding at the top to a shape of flat bars or profiles positioned at the ends of the bottom of the panels. The bottom strip forms a base of the mobile safety barrier and supports the panels in regions of their bottom ends.
Furthermore, the invention relates to a method for assembling the mobile safety barrier according to the preamble of claim 15.
The mobile safety barriers described generally above are used during road renovation or when a number of road lanes is increased, where due to the safety reasons the opposite direction lanes are fenced from each other by means of road barriers, which most often can be rearranged and used many times.
An example of one of the simplest barriers is a safety road barrier presented in the publication PL 66432 Y1 describing an industrial design titled "Safety Road Barrier". According to the aforementioned description, this barrier comprises at least two metal pillars and a metal section guide attached to them. The profile of the pillar features a shape of the upper-case Greek letter "Σ" (sigma) and is inscribed into a rectangle, which width to length ratio falls within a range from 0.5 up to 0.6, and the guide profile has two external parts, between which is inserted an internal part with a curvature opposite to the curvatures of the external parts and is inscribed into a rectangle, which width to length ratio falls within a range from 0.21 up to 0.29, whereas the internal part and the external parts of the section guide profile have a shape of isosceles trapeziums.
A barrier similar to the above described barrier is known from the publication PL 68391 Y1 titled "Industrial barrier". The said industrial barrier serves for the protection of the walls, construction structure elements, machinery and devices against impacts caused by movement of forklift and pallet trucks. The design of this barrier is characterized by a short pillar, to which a commonly known profile sheet used in the road barriers is fixed.
In turn, from the patent application description P.412418 pertaining to the invention titled "Absorbing element of a safety road barrier and a safety road barrier comprising such absorbing element", an absorbing element is known which serves for constructing a safety road barrier, which has a form of a metal, flexible thin-walled section comprising a first connecting wall having connecting means adapted to connecting to a barrier fender beam, a second connecting wall generally parallel to the first connecting wall and having connecting means adapted to connecting a barrier pillar and two deformation walls connecting the first connecting wall with the second connecting wall. In order to enable designing road barriers having the improved shock absorbing property, each deformation wall of the absorbing element is inclined at an acute angle in the vertical plane, whereas the orientation of the said inclination angle is the same for both deformation walls, and this angle amounts approximately 7°.
The barrier that can be moved is known from the PL183546 patent description titled "Safety mobile road barrier". This mobile barrier comprises at least two extreme pillars and n-middle pillars. Each extreme pillar is equipped on both sides with two pairs of connectors, each of them having a cross-section shape corresponding to the shape of the profile fender beam, with two arms at its bottom part, on which three guide strips are fixed. In turn, the middle pillar is equipped with two pairs of guide strips, and the profile fender beams are fixed in an inseparable manner on the guide strips of the extreme and middle pillars by means of screws.
Publication of the European patent application description EP1162315 pertaining to the invention titled "Concrete safety-barrier for roads" teaches a safety barrier that is constructed from a series of prefabricated concrete sections with broad bases, having metal rings anchored in their ends to receive vertical connecting bolts screwed into plates set in recesses in the base. Joints between sections are covered by inverted U-section caps with side holes for removable fixings, and the sides of the sections can be given reflective strips.
Furthermore, from a publication of the European patent description EP2664712 pertaining to the invention titled "Traffic guidance barrier element and traffic guidance barrier" is known an element of the traffic guidance barrier comprising a longitudinal body with two terminal parts and at least one connecting device positioned on each terminal part, which can be connected to the next element of the traffic guidance barrier, positioned adjacent to the element of the traffic guidance barrier. The connecting device, which is a subject of the invention, has at its front side a latch and a slot, whereas the latch cooperates with the slot of the adjacent element of the barrier. The connecting device has a locking section, which height is equal to the barrier height, and is equipped with at least one pin, or at least one element receiving the pin, whereas at least one pin or at least one element receiving the pin may be connected with the transverse part, which is equipped with at least one pin or at least one element receiving the pin, which is formed and positioned or which are formed and positioned complementarily in respect of at least one pin or at least one element receiving the pin of the locking section. Moreover, at a front side is provided a front panel, which has a slot and a latch, whereas the slot is formed as being conically tapered downwards at least along certain sections.
From the document of EP 2540913 B1 that presents similar solutions as in the document DE 202012009387 U1 and from the documents EP 2644776 A1 , EP 2664713 A2 , EP 2712962 A2 is known a safety barrier comprising mobile elements connected with each other by means of the connecting system, which comprises a rail and a connector which has at least two wall parts positioned at a specified distance from each other, in particular parallel to each other, whereas the rail is positioned in the first connecting area of the first safety barrier and the second safety barrier under the first mobile element of the safety barrier and under the second mobile element of the safety barrier. In turn, the connector of the safety barrier, disclosed in the aforementioned documents, is positioned above the rail in the second connecting area of the first mobile element of the safety barrier and the second mobile element of the safety barrier between the first mobile element of the safety barrier and the second mobile element of the safety barrier in order to create a stiffening connection of the first mobile element of the safety barrier and the second mobile element of the safety barrier in the specified arrangement towards each other.
Disadvantage of the described barriers consist in their low strength at places where the road barrier elements are connected. Furthermore, the barriers described above have complicated shapes, what in turn requires large amount of workload while assembling the road barrier and precision while connecting the elements of the road barrier with each other.
The aim of the present invention is to create a road barrier featuring an uncomplicated construction and high strength at places where the elements of the road barrier are connected.
According to the invention, the aim was achieved on the one hand by the mobile safety barrier with features of claim 1, and on the other hand by a method with features of claim 15. The preferred embodiments have been presented in dependent claims, description and figures.
A mobile safety barrier according to the invention comprising panels, quadrangle-shaped in side view, adjacent to each other at ends, with beds at the top and with bottom flat bars or profiles at the bottom, and coming into contact with each other, directly or indirectly, at least one connecting element insertable at the top and having at the bottom a shape which corresponds to the shape of the panel beds positioned in the top part of the panels, connecting means for connecting the adjoining panels with each other at the top by means of the connecting element, at least one bottom strip corresponding at the top to the shape of the flat bars or profiles situated at the ends at the bottom of the panels and insertable at the top between the arms of the bottom strip, which forms a base of the mobile safety barrier and supports the panels in regions of their bottom ends, and bottom connecting elements to connect with each other the adjoining panels at the bottom by means of the bottom strip characterised in that each bottom strip connecting the panels and forming the bases of the mobile safety barrier and supporting the panels in the regions of their bottom ends comprises one concave and opened at the top strip profile with the arms oriented upwards, which has permanent connecting elements fixed to the strip profile, going through the holes of the bottom flat bars or panel profiles, and mobile connecting elements, forming together with the permanent connecting elements the bottom elements intended for connecting the adjoining panels with each other at the bottom, and which at the bottom is fixed inseparably to the flat bar, and which embraces with its arms the bottom flat bars or profiles with the holes in the regions of the ends of the connected panels, and which are arranged as the permanent connecting elements, and the connecting element, which connects the adjoining panels with each other at the top by connecting means, which are the holes in the connecting element and the screws fixed permanently to the beds, is the flat bar or the profile which has the holes arranged as the screws fixed to the beds and which is embedded in the concave beds opened at the top and with the arms oriented upwards and formed in the regions of the ends of the adjoining panels in their top parts.
Furthermore, a method for assembling the mobile safety barrier according to the invention is characterised in that at places where panels are connected, bottom strips forming the bases of the mobile safety barrier and supporting the panels in the regions of their bottom ends are positioned, whereby each bottom strip comprises one concave and opened at the top strip profile with arms oriented upwards, and which has permanent connecting elements fixed to the strip profile, going through holes of bottom flat bars or panel profiles, and mobile connecting elements, forming together with the permanent connecting elements bottom elements intended for connecting the adjoining panels with each other at the bottom, and which at the bottom is inseparably fixed to a flat bar, and that upon putting the panels with their holes onto the permanent connecting elements embraces with its arms the bottom flat bars or profiles with holes in the regions of the ends of the panels that are being connected, and which are arranged as the permanent connecting elements, and then in concave beds opened at the top and the arms oriented upwards and formed in the regions of the ends of the adjoining panels in their top parts is positioned at the top the connecting element which is the flat bar or profile and which connects the adjoining panels with each other at the top by means of the connecting means, which are the holes in the connecting element and screws fixed permanently to the beds, arranged as the holes in the connecting element.
The basic idea of the invention is to provide the mobile safety barrier comprising the panels, which is stiffened at the connection places at the bottom by one profile with the flat bar, and at the top it is stiffened by one connecting element, which has the holes arranged as the screws fixed to the concave beds opened at the top, which simplifies connecting the panels with each other, each of which can be removed from a row of panels by an upward movement upon unscrewing the nuts creating the connecting means together with the screws assigned to them.
An increase in barrier strength and stiffness is furthermore obtained due to a fact that a fit between the connecting elements and the concave beds at the top and a fit of the bottom flat bars or profiles in the open profile at the top of the bottom strip are the slide fits, therefore there is no clearance between the connecting elements and the concave beds, and between the bottom flat bars or the profiles and the profile arms of the bottom strip, in particular when the profile of the bottom strip with the arms oriented upwards is a channel section or a profile with a cross-section with a shape chosen from a fragment of trapezium, rectangular, circle or ellipse.
In the preferred embodiment of the invention, the holes of the bottom flat bars or the profiles have internal centring surfaces at the top, and the mobile connecting elements tightened on the permanent connecting elements fixed the strip profile have external centring surfaces at the bottom, which are in contact with the internal centring surfaces, which enables an accurately positioning the adjoining panels each other, whereas the diameter of internal centring surfaces increases upwards, and diameter of the external centring surfaces decreases downwards.
According to the next embodiment it is preferred that the holes of the connecting element have internal centring surfaces at the top, and the nuts tightened on the screws fixed permanently to the beds have external centring surfaces at the bottom, which are in contact with the internal centring surfaces, which enables an accurately positioning the adjoining panels each other, whereas a diameter of the internal centring surfaces increases upwards and a diameter of the external centring surfaces decreases downwards.
Preferably, the strip profile of the bottom strip with the arms oriented upwards is the channel section. The bottom strip that is one channel section with the permanent connecting elements and the flat bar fixed to it at the bottom, which may be shorter than the strip profile, with a length equal to a length of the strip profile, or longer than the strip profile, is cheap and simple to perform. Furthermore, thanks to its simple construction, the connection of the panels with each other is not complicated, because while connecting it is sufficient to put the end of the connected panel onto the bottom strip and screw the nuts onto the permanent connecting elements in order to obtain a preliminary connection of two adjoining panels of the barrier with each other.
According to the another embodiment, it is preferred that the concave strip profile opened at the top and forming the bottom strip with the arms oriented upwards is the profile with the cross-section in a shape chosen from a fragment of a trapezium, rectangular, circle or ellipse.
The connecting element with holes under the permanent connecting elements can be the profile with the cross-section with a shape of a rectangular, which is embedded in the concave beds, or it can be the flat bar or the profile with the cross-section in a shape of a trapezium, circle or ellipse.
In turn, the concave bed can be the channel section positioned at the top at the end of the panels or a fragment of the profile with a cross-section chosen from a trapezoid, rectangular, circle or ellipse, which can be positioned at the top at the end of the panels.
The preferred development of the invention may consist in that each panel has an outline in a shape of a rectangular and comprises a top profile with side profiles forming the concave beds for the connecting element, at least one middle profile and bottom profile with side profiles formed from closed profiles embedded and fixed in the concave, open from the top profile with the arms oriented upwards and with the permanent connecting elements, which is fixed in the inseparable manner to the flat bar of the bottom strip.
A particularly preferred embodiment of the invention may consist in that at least one middle profile, the side profiles forming the concave beds and the side profiles formed from the closed profiles of the panels are connected with each other at the ends by means of vertical side profiles.
The targeted development may consist in that the panels comprise middle reinforcing profiles positioned between the vertical side profiles and fixed to at least bottom profiles and top profiles.
According to the next preferred embodiment of the invention, the middle profile is created from the sections in a shape of the upper-case letter "Σ" or the sections in a shape of the channel sections with the bent arm ends.
Preferably, in the collapse places of the road barrier axis, in which the axis of symmetry of the panel, which is being connected to the other panel, is deflected by an angle 2α from the straight line, on which the axis of symmetry of the panel is positioned, the panels are connected at the top by means of the connecting element with the arms, between which a top vertical angle is of 180° - 2α, and at the bottom the panels are connected by means of the bottom strip with the arms, between which a bottom vertical angle is of 180° - 2β, whereas the top vertical angle of 180° - 2α is equal to the bottom vertical angle, which is of 180° - 2β, and adjoining walls of the vertical side profiles in the cross-section are deflected from a straight line perpendicular to the axis of symmetry by an angle β.

Fig. 1 shows an axonometric view of a mobile safety barrier 101 with a height "h" from 500 mm up to 600 mm, and Fig. 2 and 3 show its fragments in a place where the panels 100, 200 are connected adjacent by their ends and connected at the top by means of a connecting element 300. In the embodiment shown in Fig. 1, 2 and 3 the panels 100, 200 comprising a top profile 140, 240 with side sections 110, 210 of beds 120, 220, a middle profile 150, 250 and a bottom profile 160, 260 and adjoining with each other by their ends and coming into direct contact with each other are at the bottom connected by means of bottom strips 400 or their fragments 405 with connecting elements 430. The bottom strips 400 with the width "s" from 200 mm up to 450 mm, preferably of 240 mm, apart from a function related to connecting the adjoining panels, are bases of the mobile safety barrier 101 and they support the panels 100, 200 in the region of their bottom ends. In one of the embodiments the bottom strips 400 comprise a bottom element, for example a flat bar 410 and a concave element with a convexity oriented downwards, for example a channel section 420 or a C-channel bar, which arms are oriented upwards. Furthermore, the bottom strips 400 comprise connecting elements fixed permanently, which free ends are threaded. In the embodiment of the invention shown in Fig. 1, 2 and 3, the bottom permanent connecting elements 430 are the screws, that by their bottom ends are fixed permanently to the bottom strip 400 at places positioned beyond the axis of symmetry of the bottom strip, and to be more precise, each bottom permanent connecting element 430 is fixed permanently to the channel section beyond its longitudinal axis. A length of the bottom strip 400 is equal to the sum of the lengths of insertable elements 190, 290 coming into contact with each other, from which each is positioned at the bottom at the end of its corresponding panel, respectively 100, 200, and which at the ends are connected by means of vertical side profiles 155, 255 that have a vertical axis of symmetry 102. Thanks so selected length of the bottom strip 400, adjusted in that manner insertable elements 190, 290 can be positioned in the connecting strip 400. Each insertable element 190, 290 has holes 180, 280, which are arranged, at the top view, in the same manner as the bottom permanent connecting elements 430 are arranged. The connecting elements 430 have a greater length than a sum of thicknesses of the given bottom permanent insertable element 190, 290 and a height of a nut, respectively 170, 270, what enables to immobilize the bottom permanent insertable elements 190, 290 in regard to the bottom strip 400. In another solution, the panels 100, 200 may directly come into contact with each other only in a specified place or indirectly through the aligning insert.
The aforementioned connecting element 300, which connects the adjoining panels 100, 200 with each other at the top, is the profile 310, which is embedded or put into the beds 120, 220 formed in the regions of the ends of the adjoining panels 100, 200 in their top parts. In the solution shown in Fig. 1, 2 and 3, the profile 310 has a length equal to at least a sum of lengths of the beds 120, 220, thereby there is a possibility to embed the profile 310 in the beds 120, 220, which are on the panels 100, 200 adjoining at the ends. The beds 120, 220 are concave with their convexity oriented downwards and comprise the connecting elements 130, 230 that are fixed permanently, which free ends are threaded. In the embodiment of the invention shown in Fig. 1, 2 and 3, the top permanent connecting elements 130, 230 are screws, which are fixed permanently by their bottom ends to the bottom part of the beds 120, 220 at places positioned beyond the axis of symmetry of the bottom strip, and to be more precise, each top permanent connecting element 130, 230 is fixed permanently to the side channel section, respectively 110, 210 beyond its longitudinal axis, which is a part of the respective bed 120, 220. The connecting element 300 has holes 320, which are arranged, in the top view, in the same manner as the top permanent connecting elements 130, 230 are arranged. The connecting elements 130, 230 have a length greater than a sum of thicknesses of the connecting element 300 and a height of a nut 370, what enables to immobilise the connecting element 300 in regard to the beds 120, 220 of the panels 100, 200 upon tightening up the said nuts 370.
In Fig. 4 is shown an axonometric view of the panels 100, 200, and Fig. 5 and 6 show the axonometric views of chosen fragments of the panels 100, 200, which are zoomed in. The shown panels 100, 200 comprise the top profile 140, 240 with the side channel sections 110, 210 of the beds 120, 220, the middle profile and the bottom profile 160, 260 with the bottom permanent insertable elements 190, 290, which are connected at the ends by means of the vertical side profiles 155, 255 with the front surfaces 153. Additionally, the top profile 140, 240, the middle profile and the bottom profile 160, 260, in order to increase stiffness of panel construction, may be connected with each other by means of middle reinforcing profiles 154, 254. In the embodiment of the invention the top profile 140, 240, the middle profile and the bottom profile 160, 260, the vertical side profiles 155, 255 and the middle reinforcing profiles 154, 254 have a rectangular-shaped cross-section.

The bottom insertable element 1190 in a bottom wall has an steadying hole 1181, which is slide fit with the bottom part 1131 of the bottom permanent connecting element 1430. In turn, in a top wall of the insertable element 1190, coaxially with the steadying hole 1181, there is a centring hole 1180, which diameter is greater than a diameter of a top part 1432 of the bottom permanent connecting element 1430, but smaller than an outer diameter of the spherical cap 1171 of the nut 1170, which leans on an edge 1182 of the centring hole 1180, what enables to centre the permanent connecting element 1430 in the centring hole 1180. At a bottom surface of the strip, for example on the flat bar 1410, there is a pad 1411, which prevents from damaging a road surface by the road barrier. In Fig. 26 is shown, against a background of the vertical side profile 2155, the bottom strip 2400 with a section in a shape of the channel section 2420, which arms are oriented upwards and the bottom insertable element 2190, which is a flat bar with a section in a shape of a rectangular, as well as one of the bottom permanent connecting elements 2430 and the bottom nut 2170. The bottom insertable element 2190 in a bottom surface has a steadying hole 2181, which is slide fit with a bottom part 2431 of the bottom permanent connecting element 2430. In turn, in a top part of surface of the insertable element 2190, coaxially with the steadying hole 2181, there is a centring hole 2180, which diameter is greater than a diameter of a top part 2432 of the bottom permanent connecting element 2430, but smaller than an outer diameter of a spherical cap 2171 of the nut 2170, what enables to centre the permanent connecting element 2430 w in the centring hole 2180. The bottom strip 2400 comprises the bottom element, for example the flat bar 2410. In turn, in Fig. 27 is shown, against a background of the vertical side profile 3155, the bottom profile 3400 with a section in a shape of the semi-circle 3420 and the bottom insertable element 3190 with a section in a shape of a circle, as well as one of the bottom permanent connecting elements 3430, with an axis of symmetry 3435 and the bottom nut 3170. The bottom insertable element 3190 in a bottom wall has a steadying hole 3181, which is slide fit with a bottom part 3431 of the bottom permanent connecting element 3430. In turn, in a top wall of the insertable element 3190, coaxially with the steadying hole 3181, there is a centring hole 3180, which diameter is greater than a diameter of a top part 3432 of the bottom permanent connecting element 3430, but smaller than an outer diameter of a spherical cap 3171 of the nut 3170, what enables to centre the permanent connecting element 3430 in the centring hole 3180. The bottom strip 3400 comprises the bottom element, for example the flat bar 3410 with recesses 3412. Furthermore, in Fig. 28 is shown, against a background of a vertical side profile 4155, the bottom strip 4400 with a section in a shape of the channel section 4420, which arms are oriented upwards and the bottom insertable element 4190 that is the profile with a section in a shape of a rectangular, as well as one of the bottom permanent connecting elements 4430 with an axis of symmetry 4435 and the bottom nut 4170, which are positioned beyond an axis of symmetry 4401 of the strip 4400. The bottom insertable element 4190 in a bottom wall has a steadying hole 4181, which is slide fit with a bottom part 4431 of the bottom permanent connecting element 4430. In turn, in a top wall of the insertable element 4190, coaxially with the steadying hole 4181, there is a centring hole 4180, which diameter is greater than a diameter of a top part 4432 of the bottom permanent connecting element 4430, but smaller than an outer diameter of a spherical cap 4171 of the nut 4170, what enables to centre the permanent connecting element 4430 w in the centring hole 4180. At the bottom surface of the strip, for example the flat bar 4410 with the arms oriented downwards, there is a pad 4411, which preferably increases friction between the bottom strip and the road surface, and prevents from damaging the road surface by the road barrier.
Fig. 29 shows a cross-section along the line C-C of a side profile 2255 that is a flat bar against a background of middle profiles 2150 with sections 2151 and the bed 2120, that is in this embodiment, a channel section 2121.
