Description

Technical Field

[0001] This utility model belongs to the field of highway construction technology, and in particular relates to prefabricated highway crash barrier cast-in-place formwork support. Background Technology

[0002] In the cast-in-place construction of highway crash barriers, the performance of the formwork support determines the overall stability of the formwork and ensures the integrity of the subsequent cast-in-place barrier. However, the installation process of the formwork support is cumbersome, requiring a large amount of manual operation and complex splicing procedures. The connection of various components may require a lot of time for calibration and fixing, affecting the overall progress of highway construction. Therefore, it is necessary to provide prefabricated cast-in-place formwork supports for highway crash barriers. The use of tie rods can accurately tie and position two steel formworks, effectively improving the overall stability. At the same time, the support bolts and assembly components work together to achieve diagonal bracing reinforcement, further enhancing the stability of the steel formwork and ensuring the forming quality and protective performance of the crash barrier.

[0014] Figure 1-4This invention illustrates an embodiment of a prefabricated highway crash barrier cast-in-place formwork support, comprising a support threaded tube 2 located on opposite sides of two steel formworks 1; tie rods 3 are provided at the top and bottom between the two steel formworks 1; a transverse threaded tube 8 is welded to the surface of the support threaded tube 2; a threaded top rod 9 is threadedly connected to the inner cavity of the transverse threaded tube 8; a top head 10 is fixedly connected to the end of the threaded top rod 9 away from the transverse threaded tube 8; the top head 10 is tightly fitted to the surface of the steel formwork 1; and through the combined use of the transverse threaded tube 8 and the threaded top rod 9, horizontal support is provided on the lower side of the steel formwork 1. The support further improves the stability of the steel formwork 1 after installation. The tie rod assembly 3 includes a tie rod 31, with threaded sleeves 33 threaded to both sides of the tie rod 31. The threaded sleeves 33 are pressed against the surface of the extrusion plate 32. A PVC sleeve 34 is fitted onto the surface of the tie rod 31, with both sides of the PVC sleeve 34 tightly fitted to the two steel formwork 1. The threaded sleeves 33 exert a compressive force on the extrusion plate 32, allowing the two steel formwork 1 to be subjected to opposing forces, thereby improving the stability of the steel formwork 1 after installation. Meanwhile, the PVC sleeve 34... With the combined use of the two steel templates 1, the distance between them can be positioned. A PVC sleeve 34 can also protect the section of the tie rod 31 located between the two steel templates 1, preventing concrete from contacting the surface of the tie rod 31 and facilitating subsequent disassembly of the tie rod 31. The tie rod 31 penetrates both steel templates 1. Extrusion plates 32 are fitted on both sides of the surface of the tie rod 31. An assembly assembly 4 is provided at the top of the support screw tube 2. The assembly assembly 4 includes a diagonal brace 41 slidably connected to the inner cavity of the support screw tube 2. The front and rear sides of the diagonal brace 41 are welded... The extrusion head 5 is connected to the support screw tube 2. Arc-shaped grooves 6 are opened on the front and rear sides. The extrusion head 5 is slidably connected to the inner cavity of the arc-shaped groove 6. The top of the diagonal support rod 41 is fitted with a butt plate 42. The front and rear ends of the extrusion plate 32 away from the steel template 1 are welded with fixing ears 43. One side of the fixing ears 43 is threaded with a bolt 44. The butt plate 42 is inserted into the inner cavity of the fixing ears 43. The butt plate 42 and the fixing ears 43 are fixedly connected by bolts 44. The surface of the support screw tube 2 is threaded with a threaded handle 7. The top of the threaded handle 7 is tightly fitted with the bottom of the extrusion head 5.

[0015] Working Principle: In use, the user assembles the steel template 1 to the designated position, then moves the PVC sleeve 34 between the two steel templates 1 and inserts the tie rod 31 through both templates, so that the steel templates 1 are simultaneously inserted into the inner cavity of the PVC sleeve 34. Next, the user places the extrusion plate 32 onto the surface of the tie rod 31, causing the extrusion plate 32 to engage with the surface of the steel template 1. Then, the user screws the threaded sleeve 33 onto the surface of the tie rod 31 and tightens it, causing the threaded sleeve 33 to compress the extrusion plate 32. Finally, the mating plate 42 is inserted into the inner cavity of the fixing ear 43, and the bolt 44 is threaded into the inner cavity of the fixing ear 43, thus connecting and fixing the fixing ear 43 and the mating plate 42. The user then inserts the top of the diagonal brace 41 into the bottom of the connecting plate 42, allowing the user to easily position the support screw tube 2. The support screw tube 2 is then fixed to the road surface using expansion pins. The threaded handle 7 is rotated, and as it rotates upward, it compresses the extrusion head 5, pushing the diagonal brace 41 forward. This causes the diagonal brace 41 and the support screw tube 2 to provide diagonal support to the extrusion plate 32, thus achieving diagonal support for the steel template 1. Finally, the user rotates the threaded top rod 9, causing it to rotate within the inner cavity of the transverse threaded tube 8. The combined action of the threads on the surface of the threaded top rod 9 and the threads on the inner wall of the transverse threaded tube 8 pushes the top head 10 forward, causing it to press against the surface of the steel template 1, further supporting and fixing the steel template 1.

[0016] In summary, this prefabricated highway crash barrier cast-in-place formwork support, through the setting of the tie assembly 3, provides tie positioning between the two steel formworks 1, improving the overall stability of the two steel formworks 1. At the same time, with the cooperation of the support bolt 2 and the assembly assembly 4, the steel formworks 1 are reinforced by diagonal bracing, so that the two steel formworks 1 can be stabilized, thus achieving the purpose of simple and fast assembly and high support stability.
