Description

Technical Field

[0001] This invention belongs to the field of road construction technology and relates to structural facilities for roadside and median isolation and anti-collision, specifically to a prefabricated extruded wall component for road anti-collision isolation. Background Technology

[0002] Crash barriers are structural facilities used in civil engineering to protect against vehicle collisions, primarily in bridges, highways, and similar applications. Their core functions include preventing vehicles from crossing boundaries, separating traffic flows, and buffering collision impacts. Common structural forms include cast-in-place concrete walls and precast concrete walls.

[0003] Chinese patent application publication number CN116949922A discloses an invention patent entitled "Design and Construction Method of Prefabricated Crash Barrier". The prefabricated crash barrier is installed on the upper surface of one side of a precast box girder. A concrete base is cast on the upper surface of one side of the precast box girder, extending along the length of the precast box girder. A grouting layer is laid on both sides of the upper surface of one side of the precast box girder and on both sides of the concrete base. In this invention, by casting a concrete base on the precast box girder and pre-reserving a groove at the bottom of the prefabricated crash barrier, and laying a 2cm thick grouting layer on both sides of the concrete base before hoisting, the groove aligns with the concrete base during segmented installation, and the lower surface of the groove contacts the grouting layer. This not only enables quick and accurate installation of the prefabricated crash barrier but also improves its stability through subsequent grouting.

[0004] The crash barrier assembly process described in the aforementioned patent application is no longer suitable for high-standard road and bridge construction requirements, and will have the following drawbacks and defects during construction: 1) The crash barrier is assembled and connected to the bridge deck and ground via a concrete base. The concrete base needs to be pre-installed on the precast box girder of the bridge and the ground, which increases the construction cost and delays the construction progress. 2) Both the prefabricated crash barrier and the concrete base are cast using molds. Due to the limitations of mold demolding, the pre-reserved groove at the bottom of the crash barrier and the concrete base can only be rectangular. Reinforcing bars need to be pre-embedded in the groove of the crash barrier and on the concrete base, and connected with the grout. The pre-embedded reinforcing bar process not only increases the manufacturing process of the crash barrier and the concrete base but also increases the defect rate of the product. 3) The crash barrier and the concrete base are connected by grout casting, which only has a one-time unidirectional assembly function. When some individual crash barriers are damaged and need repair, the crash barrier and the concrete base can only be broken and replaced as a set, and it is not possible to replace the crash barrier individually. Summary of the Invention

[0005] To address the aforementioned problems in the existing technology, this invention provides an extruded road crash barrier, the main component of which is extruded using a building component extrusion device.

The inside corner formed by the connection between the two inclined clamps and the top panel fits into the outside corner of the V-shaped groove II, and the inside corner formed by the connection between the two inclined clamps and the top panel is consistent with the angle of the outside corner of the V-shaped groove II.

[0013] Furthermore, the present invention provides an extruded road crash barrier, which further includes an anti-climb guardrail composed of horizontal connecting rods and arc-shaped connecting plates. The anti-climb guardrail is fixedly mounted on the top panel of the top clip via its arc-shaped connecting plates.

[0014] Furthermore, the present invention provides an extruded road crash barrier, which further includes a clamping device for connecting the main body of the wall to the column. The clamping device is disposed at the trapezoidal inner buckle boss end between the V-groove I and the inverted groove II of the main body of the wall. Alternatively, the clamping device is disposed at the trapezoidal inner buckle boss end between the trapezoidal groove and the V-groove II of the main body of the wall. Or, the clamping device is disposed within the trapezoidal groove of the main body of the wall.

[0015] Optionally, this invention provides an extruded road crash barrier, wherein the clamping device comprises an external clamp consisting of a clamping panel, clamping strips disposed above and below the clamping panel, and a clamping ring.

[0017] Furthermore, the present invention provides an extruded road crash barrier wall, which also includes an inverted ladder groove integrally extruded on the bottom surface of the wall body by an extrusion device and a ground clamp II that is fitted into the inverted ladder groove.

[0018] Ground clamp II consists of V-side plates symmetrically arranged on both sides and a U-connecting plate connecting the two V-side plates. Ground clamp II is fixed to the road surface by expansion bolts connected to the bottom end of the U-connecting plate.

[0019] The beneficial effects of the extrusion-molded road crash barrier of the present invention are as follows.

[0020] 1. Compared with the main structure of the original molded anti-collision isolation wall, the main structure of the anti-collision isolation wall of the present invention is formed by extrusion molding of building component extrusion equipment. During the extrusion process, various irregular grooves can be formed on the main structure in one step, which solves the technical problem that irregular grooves of the anti-collision isolation wall formed by mold casting cannot be demolded.

[0021] 2. The main components of the anti-collision barrier of the present invention can be detachably assembled and fixed on the road surface through V-groove I connecting ground clamps.

[0023] 4. The anti-collision isolation wall of the present invention can utilize the inner buckling boss end between the V-shaped groove I and the inverted buckling groove II of the wall body, or the inner buckling boss end between the trapezoidal groove and the V-shaped groove II, or the trapezoidal groove of the wall body to set a fixing device. Through the fixing device, the street light poles and traffic sign signal poles on both sides of the road can be arbitrarily set at any position on the outer side of the wall body 1.

[0024] The beneficial effects of the present invention are not limited to this description. For better understanding, a more detailed description is provided in the Detailed Embodiments section. Attached Figure Description

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0041] The following description, in conjunction with the accompanying drawings and specific embodiments, further elaborates on an extruded road crash barrier according to the present invention.

[0042] like Figure 1 Figure 2 As shown, the present invention discloses an extruded road crash barrier, comprising a wall body 1 and a ground clamp I 21. The wall body 1 is extruded using a building component extrusion device. Specifically, the bottom two sides of the wall body 1 are symmetrically extruded with V-shaped grooves I 11, the inner side of the wall body 1 is integrally extruded with undercut grooves I 12, and the outer side of the wall body 1 is integrally extruded with undercut grooves II 13.

[0043] like Figure 1 Figure 2 As shown, the ground clamp I21 is fitted into the symmetrical V-shaped grooves I11 on both sides of the bottom of the wall body 1, and the wall body 1 is detachably connected to the road surface through the ground clamp I21. The inverted groove I12 on the inner side of the wall body 1 is used to install the warning light source devices on both sides of the road, and the inverted groove II13 on the outer side of the wall body 1 is used to bury the road lighting and communication cables.

[0044] Figure 3 As shown, this invention discloses an extruded road crash barrier, wherein the ground clamp component I21 includes a bottom panel 2a, an inclined vertical plate 2b, and a corner plate 2c. The inclined vertical plate 2b is connected to the bottom panel 2a, and the corner plate 2c is connected to the inclined vertical plate 2b. The bottom panel 2a is connected and installed on the road surface. The external angle formed by the connection between the corner plate 2c and the inclined vertical plate 2b of the ground clamp component I21 fits into the internal angle of the V-groove I11 of the wall body 1. The angle of the external angle formed by the corner plate 2c and the inclined vertical plate 2b is consistent with the angle of the internal angle of the V-groove I11.

[0045] refer to Figure 1 Figure 2 Figure 3 As shown, when several wall panels 1 are longitudinally connected, the ground clamp I21 is pre-inserted into the V-shaped groove I11 on both sides of the bottom of two adjacent wall panels 1. After the ground clamp I21 is tightly fitted with the V-shaped groove I11 of the wall panel 1, it is connected and fixed on the road surface by expansion bolts 2f or other fastening devices or other methods.

[0046] To enhance the convenience of the warning light source device for the extruded road crash barrier of this invention, and to improve the driver's visibility of the road crash barrier during nighttime driving, further... Figure 1 Figure 2 As shown, the inverted grooves I12 on the inner side of the wall body 1 are arranged in three sections at the bottom center. Warning light sources can be spaced out within these three inverted grooves I12 on the inner side of the wall body 1. The warning light sources within these three inverted grooves I12 on the inner side of the wall body 1 provide a more obvious indication function at night.

[0047] To further improve the stability of the connection at the top between the main body sections of the extruded road crash barrier of the present invention, further... Figure 1 Figure 2 As shown, the anti-collision isolation wall of the present invention also includes an upper connector 3. The outer side of the wall body 1 is integrally extruded with a trapezoidal groove 14 by an extrusion device. The upper connector 3 is inserted into the trapezoidal groove 14 of two adjacent wall bodies 1 for mutual connection and positioning of the upper ends of the two wall bodies 1. The outer surface shape of the upper connector 3 is consistent with the inner surface shape of the trapezoidal groove 14.

[0048] refer to Figure 1 Figure 2 Figure 3 As shown, when several wall bodies 1 are longitudinally connected, the upper connector 3 is inserted into the trapezoidal groove 14 of the first wall body 1 in advance, and then the trapezoidal groove 14 of the other wall body 1 is inserted into the upper connector 3. When the upper connector 3 and the trapezoidal groove 14 of the two wall bodies 1 are tightly fitted together, the top of the two adjacent wall bodies 1 are stably connected together.

[0049] In the aforementioned embodiment of the extruded road crash barrier of the present invention, the warning light source device and the road lighting / communication cables are directly installed or buried in the inverted grooves I and II. Since the front ends of the inverted grooves I and II are open, the warning light source device and the road lighting / communication cables are exposed in the inverted grooves I and II.

[0050] To prevent excessive aging of warning light source devices and road lighting / communication cables exposed to the air, and to extend the service life of warning light source devices and road lighting / communication cables, the extruded road crash barrier wall of the present invention is further provided with embedded tubes I and II for installing or burying warning light source devices and road lighting / communication cables.

[0051] Specific Figure 1 Figure 3 Figure 4As shown, this invention discloses an extruded road crash barrier. The wall body 1 has an inverted groove I12 in which an embedded tube I41 is detachably fitted, and a warning light source device is installed inside the embedded tube I41. The front opening end of the embedded tube I41 has curved grooves 4a at the top and bottom. A transparent panel 42 is detachably fitted inside the curved grooves 4a. The light generated by the warning light source device installed inside the embedded tube I41 is scattered outwards through the transparent panel 42, effectively preventing rainwater and dust from corroding the warning light source device.

[0052] Specific Figure 2 Figure 3 Figure 5 As shown, the present invention discloses an extruded road crash barrier wall, wherein an embedded tube II 43 is detachably installed in the inverted groove II 13 of the wall body 1, and the cable is buried in the embedded tube II 43. The front opening end of the embedded tube II 43 is provided with arc-shaped grooves 4a at the top and bottom, and a face baffle 44 is detachably installed in the arc-shaped grooves 4a. The face baffle 44 can effectively prevent rainwater and dust from corroding the road lighting / communication cables.

[0053] The following description, with reference to the accompanying drawings, further illustrates the detachable connection and installation methods between the inverted groove I and the inner tube I, the inverted groove II and the inner tube II, the inner tube I and the transparent panel, and the inner tube II and the face plate in the above embodiments of the extruded road anti-collision barrier of the present invention. Specifically, the detachable connection between the inverted groove I and the inner tube I, and the inner tube I and the transparent panel are used as examples for illustration.

[0054] Reference for detachable connection between undercut groove I and inner tube I Figure 3 Figure 4 As shown, the inner tube I41 is attached to the outside of the undercut groove I12, and the positions of the upper and lower arc-shaped grooves 4a of the inner tube I41 are pressed inward. When the height of the inner tube I41 under the pressure is less than the height of the outer opening of the undercut groove I12, the inner tube II43 is pushed into the undercut groove I12.

[0055] Reference for detachable connection between embedded tube I and transparent panel Figure 3 Figure 4 As shown, one end of the transparent panel 42 is inserted into any arc-shaped groove 4a of the inner tube I 41, and the other end of the transparent panel 42 is pushed inward against the outside of another arc-shaped groove 4a of the inner tube I 41. After the opening of the inner tube I 41 expands vertically under the support of the transparent panel 42, the transparent panel 42 is fixed in its upper and lower arc-shaped grooves 4a.

[0056] In existing publicly available and used road crash barrier technologies, the auxiliary components added to the top of the crash barrier are typically connected by drilling holes in the top and using expansion bolts or threaded rods. This drilling connection process not only affects construction efficiency, but the holes in the top of the crash barrier also affect its appearance, service life, and strength.

[0057] To solve the above problems, the present invention provides an extruded road crash barrier, such as... Figure 6 Figure 7 As shown, the top two sides of the wall body 1 are integrally and symmetrically extruded with V-shaped grooves II 15 by an extrusion device, and a top clip 5 for connecting other components is provided between the two V-shaped grooves II 15. Figure 7 As shown, the top clamp 5 includes a top panel 5a and two inclined clamps 5b. The two inclined clamps 5b are symmetrically connected to both ends of the top panel 5a. The top clamp 5 is clamped into the V-shaped grooves II 15 on both sides of the top of the wall body by welding the two inclined clamps 5b to both sides of the top panel 5a. To improve the tightness of the fit between the top panel 5a and the two inclined clamps 5b and the V-shaped grooves II 15 of the wall body 1, the inside corner formed by the connection between the two inclined clamps 5b and the top panel 5a is fitted onto the outside corner of the V-shaped groove II 15, and the inside corner is consistent with the outside corner angle of the V-shaped groove II 15.

[0058] The V-shaped groove II at the top of the crash barrier improves its ease of use in road design and construction. The top clamp, when installed on the top of the barrier, is not limited by its specific location or length. When other components need to be added to the crash barrier, they can be directly welded to the top panel of the top clamp. When the top clamp is installed at the connection end between two barrier sections, it simultaneously serves as a positioning device for the top ends of the two barrier sections to connect with each other.

[0059] The following example, using the installation of anti-climb guardrails, further illustrates the technical effects of the V-shaped groove II and top clip at the top of the anti-collision isolation wall described in this invention. Figure 11 As shown, the crash barrier also includes anti-climb guardrails 6. (As...) Figure 12 As shown, the anti-climb guardrail 6 is composed of a horizontal connecting rod 6a and an arc connecting plate 6b. The anti-climb guardrail 6 is fixedly installed on the top panel 5a of the top clip 5 through its arc connecting plate 6b.

[0060] In existing publicly available and used road crash barrier technology solutions, street light poles, traffic sign and signal poles on both sides of the road are all erected by burying them in the ground. The above-mentioned buried method of street light poles and traffic sign and signal poles has poor construction convenience for installation and relocation. At the same time, it also has a great impact on road traffic during the replacement and maintenance of street light poles and traffic sign and signal poles.

[0061] To solve the above problems, the present invention provides an extruded road crash barrier, such as... Figure 6 The system also includes a clamping device 8, which is installed on the outer side of the wall body 1 for connecting the wall body 1 to the poles 7 such as street light poles and traffic sign signal poles. The clamping device 8 is installed on the outer side of the wall body in the following three connection modes.

[0062] Connection Mode 1 Reference Figure 6 Figure 8 As shown, the clamping device 8 is installed at the end of the trapezoidal inner buckle boss 1a between the V-shaped groove Ⅰ11 and the inverted groove Ⅱ13 of the wall body 1.

[0063] Connection Mode 2 Reference Figure 6 Figure 10 As shown, the clamping device 8 is installed at the end of the trapezoidal inner buckle protrusion 1a between the trapezoidal groove 14 and the V-shaped groove Ⅱ 15 of the wall body 1.

[0064] Connection Mode 3 Reference Figure 6 Figure 9 As shown, the clamping device 8 is installed in the trapezoidal groove 14 of the wall body 1.

[0065] Furthermore, the above-mentioned clamping device for the extruded road crash barrier of the present invention achieves the connection between the main body of the clamping wall and the column body such as street light poles and traffic sign signal poles through the following two structures.

Bolts 8d are provided on the outer side of the clamping panel 8a, and the clamping ring 8b is connected to the clamping panel 8a by nuts 8e. (Reference) Figure 10 As shown, the column body 7 is clamped between the clamping panel 8a and the clamping ring 8c.

[0067] refer to Figure 8 As shown, when the outer clamp 81 is set at the trapezoidal inner buckle protrusion 1a end between the V-groove Ⅰ11 and the inverted groove Ⅱ13 of the wall body 1, the angle of the inner inside corner formed after the clamping panel 8a and the clamping strip 8b are welded is consistent with the angle of the outer outside corner of the V-groove Ⅰ11 and the inverted groove Ⅱ13 of the wall body 1.

[0068] refer to Figure 10 As shown, when the outer clamp 81 is set at the end of the trapezoidal inner clamping boss 1a between the trapezoidal groove 14 and the V-shaped groove II 15 of the wall body 1, the angle of the inner inside corner formed after the clamping panel 8a and the clamping strip 8b are welded is consistent with the angle of the outer outside corner of the trapezoidal groove 14 and the V-shaped groove II 15 of the wall body 1.

[0069] Structural Pattern Two Reference Figure 7 Figure 9As shown, the clamping device 8 is an inner support clamp 82, which includes an inner clamping plate 8f, a top clamping strip 8g, and a tightening ring 8h. The top clamping strip 8g is connected vertically to the inner clamping plate 8f. The inner support clamp 82 is clamped into the trapezoidal groove 14 on the outer side of the wall body 1 by its upper and lower top clamping strips 8g. Bolts 8d are provided on the outer side of the inner clamping plate 8f, and the tightening ring 8h is connected to the inner clamping plate 8f by nuts 8e. (Reference) Figure 9 As shown, the column rod 7 is clamped between the wall body 1 and the tightening ring 8h.

[0070] refer to Figure 9 As shown, when the inner support clamp 82 is set in the trapezoidal groove 14 of the wall body 1, the angle of the outer positive corner formed after the inner clamp plate 8f and the top clamp strip 8g are consistent with the angle of the inner negative corner of the trapezoidal groove 14 of the wall body 1.

[0071] To enhance the connection strength between the main body of the extruded road crash barrier and the road surface, and to further improve the connection stability of the main body, the crash barrier of the present invention also includes a ground clamp II for connecting the main body of the wall and the road surface.

[0072] Specific examples Figure 6 As shown, the bottom surface of the wall body 1 is provided with an inverted trapezoidal groove 16 integrally extruded by an extrusion device. For example... Figure 11 Figure 13 As shown, the ground clamp II 22 is fitted into the inverted trapezoidal groove 16 on the bottom surface of the wall body 1.
