Description

Technical Field

[0001] This invention relates to the field of guardrail template technology, and more specifically, to an adjustable concrete crash barrier template device. Background Technology

[0002] Bridges, as important functional structures in municipal roads, play a crucial role in improving the urban traffic environment and promoting regional economic development.

[0003] To improve the safety of pedestrians and vehicles, guardrails are usually installed on both sides of bridges. Currently, there are two types of guardrails: steel guardrails and concrete guardrails. Concrete guardrails require the erection of formwork on the bridge and then the concrete is poured in place. Compared with steel guardrails, concrete guardrails have higher stability and safety.

[0004] Chinese patent CN213896773U discloses an adjustable concrete crash barrier formwork device, including an outer formwork and an inner formwork.

[0038] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example

[0040] The present invention will now be further described with reference to the accompanying drawings.

[0041] like Figures 1 to 9 As shown, this embodiment provides an adjustable concrete crash barrier formwork device, including an outer formwork 10 and an inner formwork 11. A fixing plate 1 is installed at the top of the outer formwork 10, and a fixing plate 2 15 is installed at the top of the inner formwork 11. The device also includes:

[0042] Support component 12 is located at the end of the inner template 11 away from the outer template 10, and the support component 12 is used to support the inner template 11;

[0043] The adjustment assembly includes a fixed sleeve 13 and a transverse sleeve 16. The fixed sleeve 13 is fixedly installed on the top of the support assembly 12, and the fixed plate 15 is installed on the bottom of the fixed sleeve 13. The transverse sleeve 16 extends from the end of the fixed sleeve 13 away from the support assembly 12. The upper snap-fit ​​seat 14 is installed on the end of the transverse sleeve 16 away from the fixed sleeve 13. The lower snap-fit ​​assembly is installed on the top of the outer template 10 and is adapted to the upper snap-fit ​​seat 14.

[0044] The working principle and beneficial effects of the above technical solution are as follows:

[0045] This invention discloses an adjustable concrete crash barrier formwork device. The inner formwork 11 is supported and installed on a support assembly 12, while the outer formwork 10 is installed on a transverse sliding sleeve 16. When lateral displacement of the transverse sliding sleeve 16 is required, the transverse sliding sleeve 16 moves laterally within a fixed sleeve 13, thereby achieving lateral adjustment of the outer formwork 10. This facilitates convenient lateral adjustment of the outer formwork 10. The outer formwork 10 is snapped onto a snap-fit ​​seat 14 via a lower snap-fit ​​assembly, which is more convenient for assembly and disassembly compared to the nut connection of a suspension rod. This invention provides an adjustable concrete crash barrier formwork device that makes both lateral adjustment and assembly / disassembly of the outer formwork 10 more convenient.

[0046] In one embodiment, the support component 12 includes:

[0047] The fixing sleeve 13 is fixedly installed on the top of the column 21;

[0048] Side support columns 22, multiple side support columns 22 are horizontally connected between the column 21 and the inner template 11.

[0049] The beneficial effects of the above technical solution are as follows:

[0050] The column 21 achieves stable erection of the inner formwork 11 through the side support column 22.

[0051] In one embodiment, the support component 12 further includes:

[0052] Inclined support column 23 is supported and connected to the inner template 11.

[0053] The beneficial effects of the above technical solution are as follows:

[0054] The installation of the inclined support column 23 improves the stability of the inner formwork 11.

[0055] In one embodiment, the regulating component further includes:

[0056] Adjusting screw 24, the adjusting screw 24 is rotatably mounted on the end of fixed sleeve 13 away from transverse sleeve 16, the transverse sleeve 16 is sleeved on adjusting screw 24;

[0057] Rotating handle 43, which is mounted on adjusting screw 24.

[0058] The working principle and beneficial effects of the above technical solution are as follows:

[0059] When the handle 43 is positioned near the column 21, it is manually rotated, causing the adjusting screw 24 located within the fixed sleeve 13 to rotate. The adjusting screw 24 causes the transverse sleeve 16, which is fitted onto it, to move laterally within the fixed sleeve 13. This, in turn, causes the upper locking seat 14 mounted on the transverse sleeve 16 to move laterally, thereby achieving the lateral adjustment of the outer template 10 mounted on the upper locking seat 14 via the lower locking assembly. This allows for the adjustment of the distance between the outer template 10 and the inner template 11.

[0060] In one embodiment, the upper snap-fit ​​seat 14 has an insertion groove 25 at its bottom end and a side snap-fit ​​groove 26 communicating with the insertion groove 25 at its side end. The lower snap-fit ​​component extends into the insertion groove 25 and is snapped onto the side snap-fit ​​groove 26.

[0061] The working principle and beneficial effects of the above technical solution are as follows:

[0062] When the outer template 10 needs to be installed on the upper snap-fit ​​seat 14, the lower snap-fit ​​component installed on the top of the outer template 10 extends into the upper snap-fit ​​seat 14 through the insertion groove 25 and snaps into the side snap-fit ​​groove 26, thereby realizing the snap-fit ​​connection between the outer template 10 and the upper snap-fit ​​seat 14, making disassembly and assembly more convenient.

[0063] In one example, the lower latch component includes:

[0064] The lower mounting base 27 is installed on the top of the outer template 10 and is set away from the fixing plate 1. The side sliding groove 28 is opened on the side end of the lower mounting base 27.

[0065] A side-fastening assembly is installed in a side sliding groove 28. The side-fastening assembly includes: a mounting block 29 that extends into a groove 25; a side mounting groove 20 that is opened at the side end of the mounting block 29; a wedge-shaped locking block 31 that is installed in the side mounting groove 20 via a spring rod 44; and the wedge-shaped locking block 31 that is locked in a side locking groove 26.

[0066] The working principle and beneficial effects of the above technical solution are as follows:

[0067] When the outer template 10 needs to be installed on the upper snap-fit ​​seat 14, the mounting block 29 extends into the upper snap-fit ​​seat 14 from the insertion groove 25. When the mounting block 29 extends into the bottom of the insertion groove 25, the wedge-shaped snap-fit ​​block 31 loses its limit on the inner wall of the insertion groove 25. Under the reset of the spring rod 44, the wedge-shaped snap-fit ​​block 31 extends out from the side mounting groove 20 and snaps into the side snap-fit ​​groove 26. In this way, the mounting block 29 and the upper snap-fit ​​seat 14 can be connected, making disassembly and assembly more convenient.

[0068] In one embodiment, the side fastening assembly further includes:

[0069] Side mounting plate 32, the cross section of the side mounting plate 32 is set with a right angle bend, the vertical section of the side mounting plate 32 is slidably connected in the side sliding groove 28, the horizontal section of the side mounting plate 32 is attached to the side end of the lower mounting seat 27, and the mounting block 29 is connected to the horizontal section of the side mounting plate 32;

[0070] Adjustment groove 33 is provided on the side end of the lower mounting base 27 and is connected to the side sliding groove 28;

[0071] Locking bolt 34 is installed on the wing of the side mounting plate 32 and fixedly connected to the adjusting groove 33.

[0072] The working principle and beneficial effects of the above technical solution are as follows:

[0073] The wedge-shaped locking block 31 extends from the side mounting groove 20 and engages with the side locking groove 26, thus enabling the mounting block 29 and the upper locking seat 14 to engage. Since the mounting block 29 is installed on the horizontal section of the side mounting plate 32, the side mounting plate 32 is engaged with the bottom of the upper locking seat 14. The vertical section of the side mounting plate 32 is slidably connected in the side sliding groove 28, thereby enabling the lower mounting seat 27 to adjust the height of the vertical section of the mounting plate 32. After adjusting to the appropriate position, the locking bolt 34 is tightened, and the locking bolt 34 is locked in the adjustment groove 33, thus fixing the vertical section of the mounting plate 32 in the side sliding groove 28.

[0074] Next, manually rotating handle 43 allows for adjustment of the distance between the outer formwork 10 and the inner formwork 11. This means that adjustments to the distance between the outer formwork 10 and the inner formwork 11, as well as the height of the outer formwork 10, can be made by tilting it towards the inner formwork 11, improving construction convenience.

[0075] In one embodiment, a rear top block 35 is installed in the side slot 26. The rear top block 35 is adapted to the wedge-shaped block 31. A limiting groove is formed on the inner wall of the side slot 26. The two ends of the limiting rod 36 extend into the limiting groove. The rear top block 35 is installed on the limiting rod 36. A spring 37 is located in the limiting groove and is connected between the inner wall of the limiting groove and the limiting rod 36. A locking block 38 is installed on the rear top block 35 through a spring rod 39. A buckle 30 is connected to the vertical section of the side mounting plate 32 through a mounting base 41. The buckle 30 is fastened to the locking block 38.

[0076] The working principle and beneficial effects of the above technical solution are as follows:

[0077] The wedge-shaped locking block 31 extends from the side mounting groove 20 and engages with the side locking groove 26, thus achieving the engagement connection between the mounting block 29 and the upper locking seat 14. Since the mounting block 29 is installed on the horizontal section of the side mounting plate 32, the engagement connection between the side mounting plate 32 and the bottom of the upper locking seat 14 is achieved. After the wedge-shaped locking block 31 engages with the side locking groove 26, it pushes the rear top block 35. The rear top block 35 drives the limiting rod 36 to move in the direction of spring 37 retraction within the side locking groove 26. The rear top block 35 drives the locking block 38 to extend out of the side locking groove 26. After pressing down the locking block 38, the buckle 30 is manually flipped upward to release the locking block 38. With the spring rod 39 resetting, the locking block 38 rises, and the buckle 30 engages with the locking block 38, thus achieving the connection between the buckle 30 and the locking block 38. In this way, the engagement between the buckle 30 and the locking block 38, combined with the engagement between the wedge-shaped block 31 and the side slot 26, provides a dual effect, improving the connection stability between the outer template 10 and the upper mounting seat 14. When further adjustment of the height of the outer template 10 is required, the locking bolt 34 is loosened, and the lower mounting seat 27 drives the outer template 10 to rise or fall, thereby achieving height adjustment of the outer template 10 on the vertical section of the side mounting plate 32.

[0078] When it is necessary to remove the outer template 10 from the upper retaining seat 14, simply push the locking block 38 towards the upper retaining seat 14. The locking block 38 drives the rear top block 35 to move in the direction of the spring 37 in the side retaining groove 26. The rear top block 35 pushes the wedge-shaped retaining block 31 from the side retaining groove 26 into the side mounting groove 20. Simultaneously, in order to overcome the limitation of the buckle 30, the locking teeth of the locking block 38 descend, the spring rod 39 retracts, and the buckle 30 gradually disengages from the locking teeth of the locking block 38. When the wedge-shaped retaining block 31 disengages from the side retaining groove 26, the buckle 30 disengages from the retaining teeth of the locking block 38. In this way, the buckle 30 and the locking block 38 are engaged, and the wedge-shaped retaining block 31 and the side retaining groove 26 are engaged simultaneously and disengaged. This completes the removal of the outer template 10 from the upper retaining seat 14.

[0079] In one embodiment, a reset torsion spring 42 is mounted on the end of the latch 30 near the mounting base 41.

[0080] The beneficial effects of the above technical solution are as follows:

[0081] When the reset torsion spring 42 is in its initial state, the buckle 30 is in the horizontal section away from the side mounting plate 32. Thus, when the buckle 30 is manually flipped upward to release the locking block 38, the locking block 38 is raised under the reset of the spring rod 39, and the buckle 30 is locked onto the locking block 38 under the reset of the reset torsion spring 42.

[0082] In one embodiment, the first fixing plate and the second fixing plate 15 are connected by tie rods, as are the bottom ends of the outer template 10 and the inner template 11.

[0083] The working principle and beneficial effects of the above technical solution are as follows:

[0084] To improve the stability of the connection between the outer template 10 and the inner template 11, the fixing plate 1 and fixing plate 2 15, as well as the bottom end of the outer template 10 and the bottom end of the inner template 11, are connected by tie rods. In this way, the top ends of the side template 10 and the inner template 11, as well as the bottom ends of the side template 10 and the inner template 11, are firmly connected.

[0085] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
