[0051] like Figure 1 , showing a structure of a segmental beam for a bridge, Figure 2 The diagram shows the construction process of hoisting and splicing multiple segmental beams for a bridge into a bridge span. Figure 1 and Figure 2 The segmental beam for bridge is formed by pouring concrete into a steel cage. This embodiment provides a steel cage frame system for the segmental beam for bridge.

[0052] Reference Figure 3 to Figure 9 The segmental beam steel cage frame system for the bridge includes a canopy, a plurality of segmental beam steel cage frames, an operating platform 15 and stairs 9, wherein:

[0053] like Figure 3 As shown, the bottom of the supporting column 5 of the canopy is buried below the ground through a reinforced concrete foundation 6, and a canopy cloth 3 is provided on the top to cover the segmental beam steel cage frame, the operating platform 15 and the stairs 9 located under the canopy; the segmental beam steel cage frame is supported on the ground; the operating platform 15 is horizontally erected on the top of the segmental beam steel cage frame and fixedly connected to the supporting column 5; a staircase 9 connecting the ground and the operating platform 15 is provided between every two segmental beam steel cage frames, and specifically, the staircase 9 is connected to the operating platform 15 by providing a stair platform 16.

[0054] In this way, multiple segment beam reinforcement cage frames are integrated and designed, and stairs 9, operating platform 15 and canopy can be shared, thereby saving land and materials.

[0055] Specifically, Figure 3The segment beam reinforcement cage frame includes a frame frame 8 formed by welding steel pipes, the interior of the frame frame 8 is welded by steel pipes to form a frame outer contour, and the reinforcement cage can be supported on the frame outer contour. Specifically, the segment beam reinforcement cage frame is provided with a round tube 10 (round steel with a diameter of 32 mm is selected in this embodiment). As an improvement, Figure 7 As shown, a positioning portion is provided on the circular tube 10 for positioning the main reinforcement on the reinforcement cage. In this way, the main reinforcement of the reinforcement cage can be positioned by the positioning portion to ensure the binding requirements of the reinforcement cage.

[0056] like Figure 7 As shown, as a further improvement, the positioning part has at least two series. In this embodiment, two series are provided, namely, the first series positioning part 22 and the second series positioning part 23. Each series has multiple positioning parts. Positioning parts of different series are arranged along the axial direction of the circular tube 10 at different set intervals (for example, the interval can be 10 cm or 12.5 cm), and the positioning parts of different series are arranged on the outer circumference of the circular tube 10 at a set angle. The rotating circular tube 10 can select positioning parts of different series to meet the requirements of the spacing of different main reinforcement cages. In this way, different series of positioning parts can be selected by rotating the circular tube 10, thereby meeting the requirements of the spacing of different main reinforcement cages.

[0057] like Figure 7 , Figure 8 and Fig. 9 As shown, a handle 19A is provided at the left end of the circular tube 10 for rotating, pulling or pushing the circular tube 10. Moreover, a left end circular ring 19C with a diameter of Ф40mm and a right end circular ring 20B with a diameter of Ф40mm are also provided on the segment beam reinforcement cage frame. The circular tube 10 is penetrated by the left end circular ring 19C and the right end circular ring 20B, and a positioning notch 19D with a set angle distribution is provided at one end of the left end circular ring 19C facing the handle. In this embodiment, the positioning notch 19D is provided at every 90° angle, and a steel bar with a diameter of Ф10mm and a length of 15mm is provided on the outer peripheral surface of the left end of the circular tube 10 along the axial direction of the circular tube, which is used as the positioning steel bar 19B, and the positioning steel bar 19B can be embedded in the positioning notch 19D. In this way, after selecting a certain series of positioning parts, the positioning steel bar 19B can be embedded in the positioning notch 19D, thereby preventing the circular tube 10 from rotating and facilitating the binding of the reinforcement cage. In this embodiment, the positioning part is a steel bar welded on the round tube 10. It can be understood that the positioning part can also be other mechanisms, for example, a positioning groove is opened on the round tube 10 or a positioning block is installed on the round tube 10, etc.

[0058] like Figure 7 , Figure 8 and Fig. 9As shown, a limiting structure is provided at the right end of the circular tube 10; when the circular tube 10 is pulled to the left along the axis direction of the circular tube 10 to move the set displacement, the limiting structure abuts against the right end circular ring 20B with a diameter of 40 mm, which is used to prevent the right end of the circular tube 10 from being separated from the right end circular ring 20B. In this embodiment, the limiting structure is a steel bar with a diameter of 16 mm and a length of 60 mm welded to the right end of the circular tube 10 and perpendicular to the axis of the circular tube 10. In this way, the right end of the circular tube 10 can be prevented from being pulled out of the right end circular ring 20B, thereby improving reliability. Moreover, when the limiting structure abuts against the right end circular ring 20B, the positioning steel bar 19B is separated from the positioning notch 19D, and when the circular tube 10 is pushed to the right along the axis direction of the circular tube 10 to move the set displacement, the positioning steel bar 19B can be embedded in the positioning notch 19D. In this way, the circular tube 10 can be rotated and positioned after being rotated to a suitable position. In addition, in this embodiment, a middle circular ring 24 with a diameter of 40 mm is also provided, and the circular tube 14 is passed through the middle circular ring. In this embodiment, the handle 19A, the positioning steel bar 19B, the left circular ring 19C and the positioning notch 19D constitute the circular tube left structural unit group 19, and the limiting structure 20A and the right circular ring 20B constitute the circular tube right structural unit group 20.

The tire frame 8 is mainly formed by welding a square steel pipe with a length of 70 mm and a width of 70 mm. The square steel pipe is welded into a whole and fixed to the support column 5 by a clamp, and is directly supported on the hardened ground. The interior of the tire frame 8 is welded with a square steel pipe with a length of 100 mm and a width of 50 mm to form the outer contour of the tire frame. The rotatable round tube 10 (round steel with a diameter of Ф32 mm is selected in this embodiment) arranged on the outer contour of the tire frame adjusts the spacing of the main reinforcement of the steel cage to ensure the production requirements of the steel cage with different main reinforcement spacing. The left end ring 19C, the right end ring 20B and the middle ring 24 are all welded to the outer contour of the tire frame. The stairs are welded with a square steel pipe with a length of 70 mm and a width of 70 mm and an angle steel with a size of ∠50×50 mm. The operating platform 15 is welded with square steel pipes and is welded to the steel cage tire frame and the stairs 9. A 5 mm thick thin steel plate is laid on the operating platform 15 as an operation and personnel walking corridor 21. A protective railing is formed by welding a 70 mm long x 70 mm wide square steel pipe on the operating platform 15. The protective railing and the steel structure such as the operating platform columns supported on the ground form the operating platform truss 13.

[0062] like Figure 3 , Figure 5 and Figure 6 In this embodiment, six round steel pipes with a diameter of Ф120mm are used as supporting columns 5, on which channel steels with a length of 120×width of 55×height of 5.3mm are welded as canopy slides 2 for sliding and telescopic canopy; 10mm thick steel plates are arranged at both ends of the canopy slide 2 as canopy slide baffles 14 to prevent the canopy from sliding out of the canopy slide 2; the canopy truss 4 is welded with a length of 70×width of 70mm square steel pipe, and the fixed end of the telescopic canopy is arranged in the middle, as the fixed end of the canopy, to realize the telescopic canopy from the middle to the two ends. Specifically, the canopy truss 4 is welded to the middle of the canopy slide 2, as the fixed end of the canopy, to realize the telescopic canopy from the middle to the two ends; the canopy truss 4 are connected as a whole by canopy truss scissors 18; the top of the canopy uses waterproof cloth as the canopy cloth 3 to cover all the canopy trusses 4 to form a canopy.
