[0020] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 As shown, a curved track beam casting structure includes:

[0022] A concrete cushion layer 1, on which a track base 101 is provided;

[0023] Steel cages 2, used for rubber tube concrete, are provided with two steel cages 2 and are located on both sides of the top of the track base 101. The steel cages 2 are arranged along the length direction of the track base 101, and the steel cages 2 on both sides are parallel and perpendicular to the track base 101;

[0024] The template 3 includes an inner plate 301 provided inside the steel cage 2 and an outer plate 302 provided outside the steel cage 2. The inner plate 301 and the outer plate 302 are both made of a plurality of wooden boards. The width of the wooden boards is determined according to the bending radius of the track beam of the house type. Wider wooden boards can be selected for areas with a large bending radius.

[0025] A reinforcing keel 4, the reinforcing keel 4 being arranged on the outside of the outer plate 302;

[0026] The tensioning mechanism 5, through which the reinforcing keel 4 is connected to the inner plate 301 on the opposite side, is used. The tensioning mechanism 5 enables the reinforcing keel 4 to improve the stability of the inner plate 301 and the outer plate 302, thereby preventing the formwork 3 from shifting or expanding during concrete pouring, thereby avoiding leakage and collapse of the concrete formwork 3 and improving the quality of concrete molding in the steel cage 2;

[0027] Specifically, the reinforcing keel 4 includes a plurality of vertical ribs 401 and a plurality of horizontal ribs 402. The vertical ribs 401 and the horizontal ribs 402 are perpendicular to each other to form a keel structure. The horizontal ribs 402 are provided with at least three groups and are located at the top, middle and bottom of the vertical ribs 401, so as to evenly apply force and ensure the stability of the formwork 3.

[0028] In order to facilitate disassembly and installation, in a further embodiment, the vertical ribs 401 are arranged at intervals and are detachably connected to the outer plate 302. In this embodiment, the vertical ribs 401 are long square timbers, and the spacing between the square timbers can be adjusted according to the bending radius of the arc track beam. When the bending radius is small, the spacing between the square timbers should be reduced. When the bending radius is large, the spacing between the square timbers can be enlarged accordingly. The vertical ribs 401 are connected to the outer plate 302 by nails.

[0029] Each group of the transverse ribs 402 includes at least two reinforcing steel bars, the transverse ribs 402 are in contact with the vertical ribs 401, and the transverse ribs 402 are connected to the inner plate 301 on the opposite side through the tensioning mechanism 5;

[0030] After installation is completed, the pulling mechanism 5 can make the horizontal ribs 402 and the vertical ribs 401 produce an interference fit, and the vertical ribs 401 generate a force on the outer plate 302 to improve the stability of the outer plate 302;

[0031] Specifically, such as Figure 2As shown, each group of the pulling mechanism 5 includes a pulling screw 501 and two butterfly clips 502. The pulling screw 501 is located between the two reinforcing steel bars and passes through the outer plate 302 and the inner plate 301 in sequence. The two butterfly clips 502 are detachably connected to the pulling screw 501 and are respectively located on the inner side of the inner plate 301 and the outer side of the reinforcing steel bars. By twisting the two butterfly clips 502, the butterfly clips 502 can generate an effective force on the inner plate 301 and the horizontal ribs 402. The horizontal ribs 402 evenly transmit the force to the outer plate 302 through the vertical ribs 401, thereby ensuring the stability of the inner plate 301 and the outer plate 302.

[0032] Removable rubber pads 503 are provided between the butterfly clip 502 and the inner plate 301 and between the butterfly clip 502 and the reinforcing steel bar;

[0033] In order to further improve the stability of the structure, the top and bottom of the outer panel 302 can be detachably connected to the reinforcement strips 6 located above and below the reinforcement keel 4; support platforms 601 are also provided on both sides of the concrete cushion layer 1, and support rods 602 are provided between the support platforms 601 and the reinforcement strips 6. The two ends of the support rods 602 are respectively in contact with the support platforms 601 and the reinforcement strips 6, thereby providing additional support effects on the top and bottom of the outer panel 302, and effectively avoiding the phenomenon of mold expansion when casting the arc-shaped track beam.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
