Embodiment 1

[0026] Such as Figure 1~3 As shown, a negative bending moment construction hanging basket in a limited space in the middle beam of a T beam includes a support base 1, and a plurality of screw rods 6 are arranged on both sides of the support base 1, and the screw rods 6 are threadedly connected with the support base 1, and the support base 1 Both sides above are provided with a foldable third guardrail 10 and a second guardrail 4. The third guardrail 10 and the second guardrail 4 are provided with a plurality of wire ropes 8, and the ends of the wire ropes 8 are provided with hooks 9, thus the structure , supported by the screw rod 6 against the T-beam shoe 13, the steel wire rope 8 is hung on the T-beam hoop 12 through the hook 9, and the lower support and hanging structure ensures the safety of the construction personnel. The foldable third guardrail 10 and the first The second guardrail 4 ensures that the hanging basket can be folded into a narrow space, is suitable for con...

Embodiment 2

[0032] Further illustrate in conjunction with embodiment 1, as Figure 1~3 As shown, determine the distance between the ribs of the two T-beams 11 and the distance between the two beam shoes 13, adjust the screw rod 6 of the hanging basket so that the distance between the screw rods 6 is between the distance between the beam ribs and the distance between the beam shoes 13, so that The hanging basket can be supported on the beam shoe 13, and the upper part is hung on the stirrup 12 of the T-shaped beam 11 through the steel wire rope 8 and the hook 9, and the upper hanging and lower supporting type is adopted to make the whole more stable and the personnel construction safer; use method: personnel Fold the hanging basket guardrail above the T-shaped beam 11, and fix it crosswise with steel wire rope 8 to prevent it from unfolding during the descent. Then adjust the screw rod 6 so that it can be supported by the beam shoe 13. Hang the hanging basket to the working position, put i...

Abstract

The invention provides a construction hanging basket with negative bending moment in the limited space of the middle girder of a T-beam and its use method. There are foldable third guardrails and second guardrails on the side. There are multiple steel wire ropes on the third guardrail and the second guardrail. The ends of the steel ropes are equipped with hooks. Foldable guardrails are used to facilitate the hanging basket to enter the T beam. In the limited space of the beam, the screw rod is used to support the beam shoe of the T-beam, and the hook is hung on the stirrup of the T-beam. The upper-hanging and lower-bracing structure makes the basket more stable as a whole. The adjusting screw uses T-beams of different widths. Beam boots have a wide range of applications, and the height of the guardrails on both sides is different, which is convenient for tensioning equipment to enter and exit. It has multiple protections, is stable and reliable, and has low cost. It is suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of negative bending moment construction of a T-beam center beam, in particular to a negative moment construction hanging basket in a limited space of a T-beam center beam and a use method thereof. Background technique [0002] The construction process of the continuous T-girder bridge deck system is complicated, the operation space is limited, the construction is difficult, the risk is high, and the requirements for safety measures are high. Negative bending moment tensioning and grouting work must be completed in the limited space of the T-beam, and work at heights, the construction platform is a key consideration. In order to ensure the safety and reliability of high-altitude operations, the construction platform is easy to operate, freely retractable, cost controllable, and combined with operations. [0003] Chinese patent CN205857036U "A kind of mobile construction hanging basket " hangs the hanging basket on the...
