[0002] The T-beam includes a middle beam extending in the longitudinal direction and a top beam connected to the upper end of the middle beam. The top beam outputs the middle beam in the transverse direction to both sides. The middle beam includes a middle beam steel frame and middle beam concrete cast with the middle beam steel frame. Some T-beams have a plurality of diaphragms distributed in the longitudinal direction on both sides of the transverse direction of the middle beam. The diaphragms include a diaphragm steel frame and diaphragm concrete cast with the diaphragm steel frame. The diaphragm steel frame is connected with the middle beam steel, and the middle beam concrete is cast with the diaphragm concrete.

The bottom template is connected to the movable base frame 51 through a lifting mechanism 9, and the upper ends of the two side templates are connected together through a longitudinal push-pull rod 10 extending in the longitudinal bridge direction. The side template can be connected to the longitudinal push-pull rod 10 movably along the longitudinal bridge direction, the lower end of the side template is hinged to the bottom template, the upper end is hinged to the upper end of the side telescopic push-pull rod 11, and the lower end of the side telescopic push-pull rod is hinged to the bottom template. The longitudinal push-pull rod is hinged to one end of an upper telescopic push-pull rod 12 driving the longitudinal push-pull rod to move toward the middle beam. The upper end of the upper telescopic push-pull rod is rotatably connected to an axle pin 13 fixed to the exposed part. The push-pull rod and the axle pin are detachably connected together. The movable base frame is provided with a running wheel 14, and the bottom template is connected with a supporting foot 15 in a lifting manner.

[0027] The process of casting the diaphragm is as follows: the diaphragm casting mold is moved to the position of the middle beam where the diaphragm is set by the mobile base and connected together, and then the two are connected by the lower pull rod to prevent movement. The height of the diaphragm casting mold is adjusted to the required height by the lifting structure, and the diaphragm steel frame is located in the diaphragm casting mold, so that the upper telescopic push-pull rod is extended to make the diaphragm casting mold and the middle beam close together, and the diaphragm casting mold and the middle beam form a diaphragm cavity, and concrete is poured into the diaphragm cavity and cast together with the diaphragm steel frame to form a diaphragm. In the process of moving the mobile base to make the diaphragm casting mold approach and move away from the middle beam, the diaphragm casting mold is located in the middle of the mobile base to improve the stability during the movement. When the mobile base approaches the middle beam to the set position, the diaphragm casting mold is moved on the mobile base beyond the mobile base and abuts against the middle beam. When demoulding, first remove the end template, then retract the side telescopic push-pull rod to disengage the side template from the diaphragm, and retract the top telescopic push-pull rod to disengage the side template from the middle beam.

A positioning through hole 45 is provided on the inner surface of the end template, and the upper transverse steel bar is inserted into the positioning through hole. The inner surface of the end template is fixed with a protrusion 46, and the positioning through hole passes through the protrusion. The upper transverse reinforcement is only located in the protrusion, and the end surface of the upper transverse reinforcement is more than 2 cm away from the inner surface of the end template. After removing the crossbar casting mold, the transverse partition has a pit formed by the protrusion, and the end of the upper transverse reinforcement is sunken in the pit, and the pit is filled with concrete to close the pit.

[0031] The process of passing the upper transverse steel bar into the transverse bridge through hole is as follows: insert an upper transverse steel bar from the side where the lower longitudinal steel bar is located on the upper side until the hook head is abutted against the upper lower steel bar, the hook head on the upper transverse steel bar is directly below the upper transverse steel bar, the scale plate is fixed on the port of the transverse bridge through hole and an upper transverse steel bar is passed through the gap, the hoop is fixed on an upper transverse steel bar and the comparison rod is directly below the upper transverse steel bar, the hoop is spaced apart from the scale plate, the upper transverse steel bar is rotated in one direction until the comparison rod is located between the near gap side reference line and the far gap side reference line of the reference line group below the gap, an upper transverse steel bar is pushed inward to the limit position so that the hook head is on the upper side higher lower longitudinal steel bar, an upper transverse steel bar is rotated in the other direction until the comparison rod is located directly below the upper transverse steel bar so that the hook head of an upper transverse steel bar is hooked in the lower limit groove, the hoop is removed from an upper transverse steel bar and the comparison plate is removed from the transverse bridge through hole; The transverse steel bar is inserted from the side where the lower longitudinal steel bar is located on the upper side until the hook head is in contact with the lower steel bar on the upper side, and the hook head on the other upper transverse steel bar is directly below the other upper transverse steel bar. The scale plate is rotated 180° to fix one upper transverse steel bar and then fixed on the port of the cross-bridge through hole, so that the other upper transverse steel bar is passed through the gap, the hoop is fixed on the other upper transverse steel bar and the comparison rod is directly below the other upper transverse steel bar, the hoop is spaced apart from the scale plate, the upper transverse steel bar is rotated in one direction until the comparison rod is located between the near-gap side reference line and the far-gap side reference line of the reference line group below the gap, the other upper transverse steel bar is pushed inward to the limit position so that the hook head is on the upper side higher lower longitudinal steel bar, the upper transverse steel bar is rotated in the other direction until the comparison rod is located directly above the upper transverse steel bar so that the hook head of the other upper transverse steel bar is hooked in the upper limit groove, the hoop is removed from the other upper transverse steel bar and the comparison plate is removed from the cross-bridge through hole. Insert two tie rods into two exhaust channels from one end of the transverse bridge through hole in a cutting knife-like manner, and set an isolation membrane sleeve on two upper transverse steel bars and two tie rods; insert the other two tie rods into two exhaust channels from the other end of the transverse bridge through hole in a cutting knife-like manner, and set another isolation membrane sleeve on two upper transverse steel bars and two tie rods. The cutter is located outside the inner end of the isolation membrane sleeve. When pouring the transverse diaphragm concrete, the concrete flows into the transverse bridge through hole from between the isolation membrane sleeve and the transverse bridge through hole. As the concrete in the transverse bridge through hole flows out, the tie rod is pulled out synchronously. The cutter is always located inside the concrete, so that the cutter cuts the isolation membrane sleeve and discharges the concrete, which increases the exhaust effect and improves the density of the concrete in the transverse bridge through hole. After the pouring is completed, the two ends of the upper transverse steel bar are connected to the two ends of the power supply to generate a short circuit and heat up to melt the isolation membrane sleeve, thereby avoiding the membrane sleeve causing poor pouring effect of concrete and upper transverse steel bars.
