Currently, the demolding of railway T-beams in China is mainly carried out using a construction method that involves segmented fabrication, assembly, dismantling, and relocation to the next construction site. This method is commonly employed in the construction of T-beam formwork. However, due to the large number of operational steps involved, it is difficult to ensure construction quality and schedule adherence, while also driving up construction costs. Moreover, this approach suffers from low construction efficiency, limited mechanization, and high labor intensity. Therefore, there is a pressing need to design a new type of railway bridge. T-beam formwork 。

　　To overcome the aforementioned technical problems, the inventors have provided a more practical new type of T-beam formwork for railway bridges. The T-beam formwork is implemented according to the following technical solution: a T-shaped beam formwork for railway bridges, comprising a base pad and an upper beam body. The base pad is mounted on the outer walls of the left and right molds; the left mold is installed above the left mold base, and the right mold is installed above the right mold base. Connection plates are welded to the lower ends of the left and right mold bases, thereby forming a lower cavity and an upper cavity when the left and right molds are assembled. Both the left and right bottom plates are placed on the ground. The upper beam body is threadedly connected between the left and right molds via a first bolt and a first screw rod, and a first steel pipe is provided on the upper beam body. The lower beam body is threadedly connected between the left and right molds via a second screw rod and a second steel pipe. A fixing plate is welded to the lower end of the assembled left and right molds, and the other end of the fixing plate is welded to the connection plate.

　　Specifically, the connecting plates are arranged in two sets, with the formwork positioned between these two sets of connecting plates; moreover, the lower ends of the two sets of connecting plates are each fitted with a slider, wherein the right slider is slidably connected to a slide rail on the right base plate, and the left slider is slidably connected to a slide rail on the left base plate. The first steel pipe has a length equal to the width of the upper part of the beam; the first steel pipe is hollow, and its diameter is greater than that of the first member. The second steel pipe has a length equal to the width of the lower part of the beam; the second steel pipe is also hollow, and its diameter is greater than that of the second screw. The first bolt is matingly engaged with the first screw, and the second screw is matingly engaged with the second bolt; furthermore, the length of the first screw exceeds that of the second screw. The left mold and the right mold have symmetrical structures, and the formwork formed by their combination has a T-shaped configuration. The length of the first steel pipe is greater than that of the second steel pipe.

　　Compared with the prior art, this novel T-beam formwork exhibits the following beneficial effects: 1. The structural design has been optimized: the T-beam formwork is equipped with a first steel pipe and a second steel pipe; when the formwork needs to be secured, the first screw passes through both the first steel pipe and the second steel pipe, thereby anchoring the formwork in place. When disassembly is required, the first screw and the second screw can be separated. 2. A right bottom plate and a left bottom plate are provided, with the right mold sliding on the right bottom plate and the left mold sliding on the left bottom plate; concurrently, a right mold base and a left mold base are installed, each supporting a mold. These two bases effectively secure the molds, further enhancing the stability of the device and improving its adaptability.
