[0023] Exemplarily, the ladder cage 2 is an existing ladder cage 2 structure, but considering that the ladder in the existing ladder cage 2 is not safe when used in the site of this embodiment due to the high height of the entire ladder cage 2, the solution of this embodiment requires first removing the ladder in the existing ladder cage 2 and then replacing it with a first steel ladder 5. One end of the first steel ladder 5 is fixed on the base 1 between two piers 7. Each turning point of the first steel ladder 5 is fixedly connected to the inner wall of the ladder cage 2, and the top of the first steel ladder 5 is fixedly connected to the platform frame, thereby ensuring the firmness of the first steel ladder 5 in the ladder cage 2 and improving safety.

[0024] The horizontal frame 11 is fixed in an inverted manner at the bottom of the Bailey beam 6. The horizontal frame 11 extends to the side of the cap beam 8, and is vertically fixed flush with the side of the cap beam 8. The horizontal frame 11 and the vertical frame 12 are existing platform frame structures. The difference is that the horizontal frame 11 and the vertical frame 12 are distributed perpendicular to each other, and then the horizontal frame 11 is fixed in an inverted manner at the bottom of the Bailey beam 6, so that construction personnel can move from the horizontal frame 11 and the vertical frame 12 to the cap beam construction platform.

[0025] The horizontal frame 11 is connected to the Bailey beam 6 in an inverted hanging manner through at least four first pairs of tie rods 9, one end of at least four first pairs of tie rods 9 is fixedly connected to the horizontal frame 11, and the other end of at least four first pairs of tie rods 9 is fixedly connected to the Bailey beam 6. At least four first pairs of tie rods 9 are distributed in a rectangular shape on the horizontal frame 11, and a first force-bearing rod 10 is fixedly connected between two adjacent first pairs of tie rods 9 to form a rectangular frame. The horizontal frame 11 is invertedly hung at the bottom of the Bailey beam 6 through at least four first pairs of tie rods 9, and the force-bearing rods are connected between the four first pairs of tie rods 9, so that the horizontal frame 11 is evenly and stably stressed, ensuring that the horizontal frame 11 can be firmly at the bottom of the Bailey beam 6.

[0026] The vertical frame 12 is connected to the Bailey beam 6 through at least two second pairs of tie rods 13, one end of at least two second pairs of tie rods 13 is fixedly connected to the Bailey beam 6, and the other ends of at least two second pairs of tie rods 13 are respectively fixedly connected to the two sides of the vertical frame 12; at least two second pairs of tie rods 13 are fixedly connected to the other ends of at least four first pairs of tie rods 9; a second force rod is fixedly connected between at least two second pairs of tie rods 13, the number of the second force rods is two, the two second force rods are spaced apart on the second pair of tie rods 13, and the connection between the second force rod and the second pair of tie rods 13 is the connection between the first pair of tie rods 9 and the second pair of tie rods 13; the first pair of tie rods 9, the first force rod 10, the second pair of tie rods 13 and the second force rod form a cubic frame surrounding the outside of the Bailey beam 6. The two second pairs of tie rods 13 cooperate with the first pair of tie rods 9 and the second force rod, so that the vertical frame 12 embraces the Bailey beam 6 and will not tilt away from the cap beam 8.

[0027] The ladder cage 2 is fixedly connected to the two piers 7 through two column frames, which are formed by splicing a plurality of rods in sequence, and the column frame has a column holding area, which is sleeved outside the pier 7. The column holding frame is formed by a rectangular frame and high-strength tie rods, and the inner area of ​​the rectangular frame is the column holding area, which is sleeved outside the pier 7. The ladder cage 2 and the rectangular frame are fixedly connected by high-strength tie rods, so that the ladder cage 2 and the pier 7 are fixedly connected.

[0028] Guardrails 4 are arranged around the vertical frame 12. By arranging the guardrails 4, safety is improved, and guardrails 4 are also arranged around the horizontal frame 11 at the same time, so that the safety of the construction workers walking on it is guaranteed.

[0029] A second steel ladder 14 is provided in the vertical frame 12, one end of the second steel ladder 14 is connected to the horizontal frame 11, and the other end of the second steel ladder 14 is connected to the top plane of the cap beam 8. By providing the second steel ladder 14, it is convenient for construction workers to move in the vertical frame 12.

[0030] Each section of the second steel ladder 14 is provided with a skirting board 3. It should be noted that skirting boards 3 can also be provided around the platform frame, and by providing the skirting boards 3, debris on the platform frame can be effectively prevented from falling from a high altitude.

[0031] The top of the vertical frame 12 is flush with the top plane of the cap beam 8, or the top of the vertical frame 12 is higher than the top plane of the cap beam 8. By arranging the vertical frame 12 in this way, the protection construction personnel can smoothly reach the cap beam construction platform.

[0032] In the above-mentioned embodiment, both the first pair of tie rods 9 and the second pair of tie rods 13 are high-strength tie rods.

[0033] The construction process of the high-altitude conversion platform for the cap beam construction ladder cage of this embodiment is as follows: first, the platform frame is welded and bolted on the ground to form an integrated assembled platform, the first steel ladder 5 and the second steel ladder 14 are welded on the ground to form a whole and welded to the platform frame, which can ensure the safe passage of construction workers, and the position of the skirting board 3 fully covers the lower side of each section of the second steel ladder 14, effectively preventing debris on the platform frame from falling from a high altitude. Then the platform frame is fixedly connected to the Bailey beam 6 using high-strength tension rods and force rods to ensure that the entire cap beam construction ladder cage high-altitude conversion platform can be hoisted as a whole, completing the overall assembly and applying it between the two piers 7. The ladder cage 2 is connected to the platform frame, and construction personnel can climb the first steel ladder 5 of the ladder cage 2 to the platform frame, and then walk to the outside of the cap beam 8 through the horizontal frame 11 of the platform frame. The second steel ladder 14 installed on the vertical frame 12 can be climbed to the cap beam construction platform, thereby solving the problem that when the construction area is a double-column pier cap beam 8, the foundation of the combined ladder cage 2 installed on the outside of the double-column pier is unstable, and if it is installed in the center of the double-column pier, there is a problem that the ladder cage 2 channel cannot directly reach the cap beam construction platform.

[0034] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
