預鑄 rail rail wall panel

The invention relates to a structural engineering and concrete concrete technology related to a concrete rail rail wall panel in a rail and mass transportation system.

There are a variety of flawless rail structures, designed to be built around the world for overhead, ground or underground rail/mass transport systems such as direct-fixed rails, low-shock rails, Shinkansen-plate rails, and Rheda2000 slab rails. Some rails are fixed on the ground, some are on the job site, and the design of the concrete is used.

Rail siding is one of the rail structures, and is designed for construction quality that is difficult to control, depending on the local accessibility, construction, formwork and scaffolding. On-site sturdy rail siding requires a long working time due to the use of fixed systems, rails and all in-line components, stencil cages and the process of adjusting the final structural height.

Therefore, the inventor developed a system for concrete concrete rail siding, which was designed and adjusted to provide adequate fixed system design according to internationally recognized standards by designing and adjusting its dimensions, reinforcement and all embedded components. This problem. The engineering quality and structural service life can be improved by this type of concrete rail siding.

The upper part of the rail siding is a factory-made L-type L-shaped structure, which can control the engineering quality between the square opening and the fixed component. Some reinforcement may protrude from these openings and more securely join the secondary structure or concrete slab that secures the entire in-situ concrete and shear connectors.

In the jaw system, the fixed plastic sleeve is simultaneously twisted with the concrete rail siding. The spacing between the inserted components/fixed components varies according to customer specifications and requirements. The steel reinforcement of the concrete rail siding of the concrete type includes longitudinal reinforcement and reinforcement. Its position and spacing are designed and adjusted to retain its stress during transportation and handling operations.

The following preparations for concrete substructures or concrete slabs are similar to conventional in situ systems. Its concrete surface is rough and provides a proper fixing function. The shear connectors can be pre-embedded in the secondary structure or later mounted in a plastic insert that has been clamped to the secondary structure.

After the concrete rail siding is transported to the site, these components can be placed in place and secured to the rails and fixtures. The alignment and level of the entire rail facility are adjusted in accordance with relevant regulations. The concrete can then be poured from the opening and the crucible element is secured to the secondary structure from below by the protruding reinforcement of the concrete rail siding and the shear connectors of the secondary structure.

The present invention is directed to the development of a concrete concrete rail retaining wall panel for a conventional in-situ concrete rail retaining wall panel system for modifying the quality of the project and the service life of the structure. The cost of structural construction can be saved because of improvements in these areas.

1, 2 and 3 illustrate the characteristics of the concrete concrete rail siding elements of the present invention, installed in concrete substructures and concrete slabs, and in all of the inlaid components. The rail siding has an L-shaped cross section, wherein the first longitudinal structure (11), that is, the upright bracket, is parallel to the second longitudinal structure (14). To avoid damage to the train derailment, the height of the first longitudinal structure is higher than the second longitudinal structure.

The height of the first longitudinal structure (11) and the second longitudinal structure (14) differ by 2.4 to 5.7 meters, which is the appropriate height difference for operation and drainage of each rail siding.

The top ends of the first longitudinal structure (11) and the second longitudinal structure (14) are higher than the top ends of the lateral structures (13), the transverse structures joining the first longitudinal structure and the second longitudinal structure at equal intervals Things. The spacing of the transverse structures is determined by the fixed spacing specified by the design. The plastic spigot is embedded in each lateral structure (13) for fixed installation of the worksite.

Rail siding has 3 sets of steel reinforcement, such as longitudinal reinforcement (7) and transverse stirrups (8, 9). The first stirrup (8) is stiffened in a straight direction along the first longitudinal structure (11). The second stirrup (9) is located in the first longitudinal structure (11) and the second longitudinal structure Between the objects (14), the reinforcement of the horizontal connection is performed.

The opening or seal (2) is located between the two longitudinal structures (11, 14) and the center of the transverse structure (13). Therefore, the steel reinforcement (7, 9) located at the opening is formed by the opening and is completely embedded and fixed in the concrete of the construction site.

The design and joint interface of all openings shall be in accordance with the dimensions of the plastic insert (5), which is pre-embedded in the substructure or concrete slab below to facilitate the shearing or fixing bolts (6) )installation. The shear connectors are designed as L or U-shaped steel bars that protrude from the secondary structure or concrete slab, while the size, appearance and location of the openings depend on the type of shear connectors.

The plastic clips (10) are fixed between the steel reinforcements, and they extend laterally to contact each other to avoid stray currents generated by the steel bars. At the end of each rail siding, the flat steel strip (12) is fixed under the longitudinal steel reinforcement (7) to allow stray current to flow out of the rail siding to avoid erosion of the steel. After the rail siding is installed, all the flat bars can be welded to the main system.

The plastic inserts (4) used for several conductive rail systems are embedded in the outside of the first longitudinal structure (11) as specified by the manufacturer's specifications.

For the installation of rail siding, a set of rail siding is fixed to the rail with all the fixing components, and then the rail alignment and level adjustment are carried out according to the design regulations. Below the railway siding and substructures, appropriate spacing should be provided, depending on the engineering structure and quality control at design time. The shear connectors (fixing bolts) shall be installed and all forms shall be assembled to close all gaps below the railway siding and substructures. The concrete can then be poured into the opening/sealing to fill all the gaps and complete the construction of the railway siding.
