Description

Technical Field

[0001] This invention relates to an integrated prefabricated structure for crash barriers and railings, and its construction method. Background Technology

[0002] In the field of prefabricated high-rise building components, after years of exploration, the prefabrication technology of columns, cap beams and box girders has become increasingly mature, while crash barriers have become the final piece of the puzzle in the prefabrication of high-rise building components.

[0003] There are three main construction methods for crash barriers: 1. Casting on-site after the box girder is erected (cast-on-site type); 2. Prefabricating the crash barrier and splicing it with the erected box girder (prefabricated assembly type).

[0004] Cast-in-place crash barriers require on-site work such as rebar tying, formwork installation, and concrete pouring, which not only affects the construction period but also pollutes the surrounding environment. Precast crash barriers, on the other hand, require consideration of the alignment between the pre-reserved rebar in the crash barrier and the pre-reserved rebar on the top surface of the box girder, and also require grouting or wet splicing with high-strength concrete for connection, which is more difficult to operate and has low construction efficiency.

[0005] To address the aforementioned issues, the optimal construction method for crash barriers is integrated beam-railing construction. Due to the integrated molding process, it is crucial to ensure the construction precision of the crash barrier (cross-sectional dimensions, alignment, and angles).

[0006] Therefore, a prefabricated structure and construction method integrating anti-collision wall beams and railings are proposed to address the above problems. Summary of the Invention

[0007] The purpose of this invention is to overcome the existing defects and provide an integrated prefabricated structure and construction method for anti-collision wall beams and railings.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0050] The invention will now be further described with reference to the accompanying drawings.

[0051] like Figures 1-10As shown, an integrated prefabricated structure for a crash barrier beam includes a crash barrier operation platform 1 and a crash barrier cross slope simulation platform 2. The crash barrier operation platform 1 is used to fix the outer formwork side support rods 6 and facilitates the binding of the outer steel bars and the installation of embedded parts on the crash barrier. One operation platform can simultaneously meet the construction needs of the left and right crash barriers. The crash barrier operation platform 1 is located to the left of the crash barrier cross slope simulation platform 2. The box girder 10 is connected to the crash barrier cross slope simulation platform 2. The surface slope of the crash barrier cross slope simulation platform 2 is 2%, which is the same as the cross slope of the box girder 10. Multiple crash barrier anti-overturning support rods 3 are connected at equal intervals to the lower end of the box girder flange plate 11 on the left side of the box girder 10. The crash barrier anti-overturning support rods 3 are square tubes, and wedge-shaped wooden blocks are set between the upper end of the crash barrier anti-overturning support rods 3 and the box girder flange plate 11. Multiple sets of anti-collision wall template components are connected to the left side of the box girder body 10 and the upper end of the anti-collision wall operating platform 1. The anti-collision wall template components include an outer anti-collision wall mold 4 and an inner anti-collision wall mold 41. The outer mold side support rod 6 and the outer mold lower support rod 7 are connected to the upper end of the anti-collision wall operating platform 1.

The right end of the outer mold bottom buckle plate 5 is tightly connected to the box girder flange plate 11. The left side of the outer mold 4 is connected to the upper end of the outer mold side support rod 6. The upper end face of the box girder 10 is connected to the upper support rod 8 and the lower support rod 81 of the inner mold, respectively. The upper support rod 8 of the inner mold is connected to the upper right side face of the inner mold 41 of the crash barrier, and the lower support rod 81 of the inner mold is connected to the lower right side face of the inner mold 41 of the crash barrier. The upper end faces of the outer mold 4 and the inner mold 41 of the crash barrier are connected to the side mold connecting plates 9. The side mold connecting plates 9 are set every 2m and arranged on the top of the side mold to connect the inner and outer molds into a whole. The upper end face of the inner mold 41 of the crash barrier is connected to a turnbuckle 12. The turnbuckle 12 is used to adjust the top alignment of the crash barrier.

[0052] Specifically, this structure ensures that the posture of the integrated beam-railing prefabrication is consistent with that of the box girder after erection by maintaining the erection state of the box girder body 10, thus avoiding local loads during construction that could cause the box girder to overturn. This achieves consistency between the integrated beam-railing prefabrication and the girder erection posture, solving the accuracy problem in the prefabrication process of the crash barrier, realizing integrated beam-railing prefabrication, and simultaneously ensuring the efficiency of formwork installation and dismantling.

[0053] Specifically, in the multiple sets of crash barrier template components, flange plates and bolts are used to connect every two adjacent outer molds 4 and every two adjacent inner molds 41. The outer molds 4 and inner molds 41 are manufactured symmetrically, one every 2m, with 1cm thick steel plates as the face panels and steel plates as purlins. Adjacent templates are connected by flange plates and high-strength bolts, and straight lines can be achieved by adjusting the bolt tightness and installing thin rubber plates.

[0054] Specifically, in the multiple sets of crash barrier template components, positioning steel bars (not shown in the figure) are installed between every two adjacent outer molds 4 and between every two adjacent inner molds 41. The positioning steel bars are arranged at 1m intervals to ensure the installation position of the outer molds 4 and inner molds 41 of the crash barrier.

[0055] Specifically, the upper right side of the inner mold 41 of the crash barrier is connected to the first connecting plate 14, the lower right side of the inner mold 41 of the crash barrier is connected to the first connecting seat 15, the upper end of the box girder body 10 is connected to the second connecting seat 13, the lower ends of the upper support rod 8 and the lower support rod 81 of the inner mold are connected to the second connecting seat 13, the upper end of the upper support rod 8 of the inner mold is connected to the lower end of the first connecting plate 14, and the upper end of the lower support rod 81 of the inner mold is connected to the first connecting seat 15.

[0056] Specifically, the side mold connecting plates 9 are multiple pieces, which are connected at equal intervals to the upper surfaces of the outer mold 4 and the inner mold 41 of the crash barrier; the upper left side surface of the outer mold 4 of the crash barrier is connected to the second connecting plate 16, and the two ends of the side mold connecting plates 9 are respectively connected to the second connecting plate 16 and the first connecting plate 14 connected to the upper surface of the inner mold 41 of the crash barrier.

[0057] Specifically, the upper end of the crash barrier operating platform 1 is connected to the third connecting seat 22, the lower end of the left side of the crash barrier outer mold 4 is connected to the fourth connecting seat 17, the upper end of the outer mold side support rod 6 is connected to the fourth connecting seat 17, and the other end is connected to the third connecting seat 22. The outer mold side support rod 6 controls the elevation while preventing the crash barrier outer mold 4 from floating.

[0058] Specifically, the outer formwork bottom plate 5 includes a bottom formwork connecting plate 18 and multiple screw connecting channels 19. The lower end of the bottom formwork connecting plate 18 is connected to multiple screw connecting channels 19 at equal intervals. Each screw connecting channel 19 connects two bottom formwork connecting screws 20. The lower bottom surface of the outer formwork of the crash barrier 4 is connected to a fixed connecting seat 21. The upper ends of the two bottom formwork connecting screws 20 pass through the fixed connecting seat 21 on the lower bottom surface of the outer formwork of the crash barrier 4. The upper end of the bottom formwork connecting plate 18 is tightly fastened to the lower end face of the box girder flange plate 11. The bottom formwork connecting plate 18 is tightly fastened to the lower part of the box girder flange plate 11, serving to stop grout flow.
