Description

Technical Field

[0001] This invention relates to the field of railway bridge deck construction technology, and in particular to an adjustable three-wall formwork for high-speed railway bridge decks that does not require drilling. Background Technology

[0002] In the construction of railway bridge decks, the "three walls" are important components. The three walls refer to the A wall, the B wall, and the protective wall. The protective wall is mainly used to prevent accidental impacts, wind loads, and other external factors, protecting the tracks and trains from damage, while also providing a certain degree of sound insulation. The A wall formwork is the outer vertical wall of the high-speed railway bridge, used to fix the outer cover plate and form the outer wall of the cable trough. The B wall is used to divide the strong and weak current cable troughs and support the cable trough cover plates.

[0003] In existing railway projects, the three-wall structure is mostly constructed using steel formwork. However, steel formwork presents problems such as high positioning difficulty, low installation efficiency, and poor control over the alignment of the three walls. The formwork often uses pre-embedded tie rods for water-stop fixation, but these tie rods cannot be reused after construction, and the surfaces of the three walls require grinding at the locations of the pre-embedded tie rods. In addition, the formwork often uses the method of drilling holes and installing rebar on the bridge deck for reinforcement, and the bridge deck needs to be repaired after the three walls are constructed.

[0004] Therefore, it is necessary to develop a high-speed railway bridge deck adjustable three-wall formwork that does not require drilling to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to design an adjustable three-wall formwork for high-speed railway bridge decks that does not require drilling in order to solve the above problems.

[0007] Specifically, the protective wall template assembly includes multiple vertically distributed first fixing rods and a first fixing plate. The multiple first fixing rods are evenly distributed along the length of the first fixing plate. The lower ends of the multiple first fixing rods are connected to the outer side wall of the first fixing plate, and the upper ends of the multiple first fixing rods are respectively connected to multiple top anchor plates.

[0008] Specifically, the three-wall formwork also includes multiple first nuts and multiple first washers. The upper end of the first fixing rod is formed as a screw, and a first through hole is formed on each top anchor plate. The upper end of the first fixing rod passes through the first through hole and then through the first washer before threadedly engaging with the first nut.

[0009] Furthermore, the B-wall formwork assembly includes multiple vertically distributed second fixing rods, multiple vertically distributed third fixing rods, a second fixing plate, and a third fixing plate. The multiple second fixing rods are evenly distributed along the length direction of the second fixing plate, and the multiple third fixing rods are evenly distributed along the length direction of the third fixing plate. The lower ends of the multiple second fixing rods are connected to the outer wall of the second fixing plate, and the lower ends of the multiple third fixing rods are connected to the outer wall of the third fixing plate. The upper ends of the multiple second fixing rods and the upper ends of the multiple third fixing rods are respectively connected to multiple top anchor plates.

[0010] Furthermore, the three-wall formwork also includes multiple second nuts, multiple second washers, multiple third nuts, and multiple third washers. The upper ends of the second and third fixing rods are both formed as threaded rods. Correspondingly, a second through hole and a third through hole are formed on each top anchor plate. The upper end of the second fixing rod passes upward through the second through hole and then through the second washer before threadedly engaging with the second nut. The upper end of the third fixing rod passes upward through the third through hole and then through the third washer before threadedly engaging with the third nut.

[0011] Furthermore, the A-wall formwork assembly includes multiple vertically distributed fourth fixing rods and a fourth fixing plate. The multiple fourth fixing rods are evenly distributed along the length of the fourth fixing plate. The lower ends of the multiple fourth fixing rods are connected to the outer side wall of the fourth fixing plate, and the upper ends of the multiple fourth fixing rods are respectively connected to multiple top anchor plates.

[0012] Furthermore, the three-wall formwork also includes multiple fourth nuts and multiple fourth washers. The upper end of the fourth fixing rod is formed as a screw, and a fourth through hole is formed on each top anchor plate. The upper end of the fourth fixing rod passes upward through the fourth through hole and then through the fourth washer before threadedly engaging with the fourth nut.

[0013] Furthermore, the first anchoring structure includes an outer support plate fixing pad, an outer support plate fixing nut, and an exposed railing threaded rod of the cover plate. The exposed railing threaded rod of the cover plate is U-shaped, with its middle part embedded in the cover plate and both ends placed on the top of the cover plate. The outer support plate fixing pad is installed at the lower end of the outer support plate, and the outer support plate fixing pad is provided with multiple fifth through holes. The exposed railing threaded rod of the cover plate passes upward through the fifth through holes and engages with the outer support plate fixing nut threadedly.

[0014] Furthermore, the second anchoring structure includes a first strut, a diagonal strut, and pre-embedded anchoring steel bars in the track slab. One end of the pre-embedded anchoring steel bars in the track slab is embedded in the high-speed railway bridge deck. The first end of the first strut and the first end of the diagonal strut are both connected to the upper end of the pre-embedded anchoring steel bars in the track slab. The second end of the first strut is used to support the inner bottom of the inner support plate, and the second end of the diagonal strut is used to support the inner middle of the inner support plate.

[0015] The beneficial effects of this invention are as follows: This invention standardizes and combines construction templates, enabling rapid assembly and saving time compared to traditional protective wall, A-wall, and B-wall templates. This accelerates project progress and saves manpower. By introducing a template structure consisting of a top anchor plate, fixing rods, and fixing plates, this invention optimizes the traditional template structure with its water-stop tie rod reinforcement. This allows for reuse in different construction projects, significantly reducing construction costs and improving the appearance quality of the three walls. The fixing rods are installed on the top anchor plate with nuts, and the position of the fixing plate can be adjusted by changing the position of the fixing rods to adapt to the construction of three walls of different widths. The support plates are fixed using the existing bridge deck structure, avoiding damage to the bridge deck concrete caused by fixing templates with drilled anchor bars. This invention also has the advantages of simple and compact structure, low manufacturing cost, and ease of use. Attached Figure Description
