DETAILED DESCRIPTION

[0040] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0041] It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and "second" information may also be referred to as "first" information.

[0042] like Figures 1 to 17 As shown, the embodiment of the present invention provides a new type of fully assembled integrated industrialized system for rails, which includes a foundation, a pier, a cap beam and a track beam arranged in sequence from bottom to top. Specifically, the foundation has embedded bars arranged vertically and extending from the top surface of the foundation to the outside of the foundation. The pier includes a first steel cage and a first template. The first steel cage includes vertically arranged longitudinal bars and horizontally arranged positioning bars. The longitudinal bars correspond to the embedded bars one by one. The positioning bars are used to connect the longitudinal bars. The first template is arranged on the sides of the first steel cage and covers the first steel cage. The longitudinal bars and the positioning bars are tied in the prefabrication plant, and then the first template around the first steel cage is cast through the mold table. Then the casted first steel cage is transported to the site and hoisted to the top of the foundation by mechanical equipment. The embedded bars of the foundation are inserted into the first steel cage and overlapped with the longitudinal bars. Concrete is poured into the first steel cage to complete the installation of the pier. In this way, the assembled pier body is completed by prefabrication, and only the hoisting and concrete pouring work need to be completed on site, without the need for formwork, and the construction is simple and the production cost is low.

[0043] Optionally, in order to improve the connection strength between the longitudinal bars, the positioning bars are preferably steel meshes. Furthermore, the positioning bars are welded to the longitudinal bars and evenly arranged in the vertical direction, and the spacing between adjacent positioning bars is 0.5-1.5m. The spacing between adjacent positioning bars is fixed, and the operator can quickly confirm the height of the pier by measuring the number of positioning bars.

[0044] It should be noted that, based on the different installation methods of the first formwork, the pier is divided into two structural forms: integrated and separated. The longitudinal reinforcement of the integrated pier is cast into the first formwork, and the first formwork and the first steel cage are cast into an integrated structure by concrete pouring, while the first formwork of the separated pier is fixedly connected to the first steel cage by the tension screws formed by the locating bars extending outside the first formwork, and the first formwork and the first steel cage are separated from each other.

[0045] Similarly, the cap beam includes a second steel cage and a second formwork. Specifically, the second steel cage includes longitudinal force-bearing surface steel bars, waist bars, stirrups, tension bars and longitudinal force-bearing bottom steel bars. The second formwork includes side panels, bottom panels and baffles. First, the steel bars are connected in the prefabrication plant to complete the binding of the second steel cage. After the second steel cage is made, the concrete pouring of the side panels and bottom panels is completed in the prefabrication plant, so that the second steel cage, the side panels and the bottom panels form a whole. The structure and force characteristics of the side panels are equivalent to reinforced concrete beams. A baffle is set at the end of the cap beam. The baffle is a prefabricated concrete panel. The baffle is connected to the side panel through a connector. The connector is preferably a screw and a nut. The screw is embedded in the two ends of the side panel. The baffle is the same width as the cap beam. Screw holes are reserved at the corresponding positions of the baffle and the screw. After the baffle is positioned and installed, the nut is tightened. After the cap beam is installed, it is transported to the construction site, hoisted to the top of the pier, and concrete is poured to complete the installation of the cap beam.

[0046] Optionally, a connection node is provided between the pier and the cap beam, and the connection node includes a support plate and reinforcing steel bars. When the pier is connected to the cap beam, the short side longitudinal bars of the pier extend into the cap beam, and the long side longitudinal bars are cut off at the top of the pier, and a support plate is embedded along the short side direction and reinforcing steel bars are embedded along the long side direction at the top of the pier; the cap beam is hoisted to the top of the pier to complete the positioning installation; a compression rod is provided on the top of the cap beam, and the cap beam and the pier are temporarily fixed with the compression rod on the top of the cap beam, and the compression rod is anchored through the longitudinal bars and fasteners of the pier; after the concrete of the cap beam reaches a predetermined strength, the compression rod is removed, and the longitudinal bars of the pier extending out of the range of the cap beam are cut off.

[0047] The track beam includes a steel frame with a "U"-shaped cross section and a third template arranged on the sides of the steel frame. A partition is arranged inside the steel frame, and the steel frame and the partition form a first chamber, a second chamber and a third chamber. The connection between the steel frame and the third template is completed in the prefabrication plant. The third template is connected to the steel frame through nuts and screws. The screws are welded to the steel frame. After the third template is installed on the side of the steel frame, the nuts are installed to achieve a fixed connection between the third template and the steel frame and anti-corrosion treatment is applied. After the track beam is transported to the construction site, it is hoisted to the top of the cap beam and concrete is poured to complete the installation. The first chamber is poured with concrete along the entire span, and the second and third chambers are poured with concrete only within a certain range of the support nodes according to actual design requirements.

[0048] Furthermore, the partition includes a horizontally arranged transverse partition and a vertically arranged vertical partition. In order to facilitate operators to pour concrete, reserved holes are provided on the transverse partition, and operators can pour concrete into the first chamber, the second chamber and the third chamber through the reserved holes.

[0049] It should be noted that if Figure 2 As shown, in general, there are only two parallel track beams on the cap beam, and the two track beams extend to form a track system. Of course, under the condition of ensuring the stability of the entire system, the track beam can also be provided with three or more, and the cap beam is also extended. At this time, in order to ensure the stability of the entire structural system, it is necessary to add piers to form a double pier or multi-pier structure, such as Figure 3 As shown, there are three track beams, and in order to ensure the stability of the system, the piers are set as double pier structures.

[0050] In summary, the new fully assembled integrated industrialized rail system provided by the embodiment of the present invention includes a foundation, piers, cap beams and rail beams arranged in sequence from bottom to top, the foundation is cast with concrete, and the piers, cap beams and rail beams are all constructed with prefabricated steel cages and concrete formwork. Compared with the prior art, each steel cage and side panel in the new fully assembled integrated industrialized rail system are prefabricated in a prefabrication plant, with high processing accuracy, high reliability, and fully hollow component transportation, which greatly improves the construction speed. Only concrete needs to be cast on site, and the construction is simple. The side panels do not need to be disassembled after the concrete is cast, which is green and environmentally friendly.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
