Problems solved by technology

But this hanging basket still has the following defects: (1) its structure is a semi-closed structure, the top of the hanging basket is not closed, and the air can enter the hanging basket through the steel wire mesh on the top of the hanging basket and around it, which is not conducive to the preservation of concrete
(2) The removal of the hanging basket still needs to be dismantled as a whole on the spot, and

Example Embodiment

[0024] like Figure 1 to Figure 6 As shown, the fully enclosed hanging basket of the present invention includes a load-bearing device, a suspension system, a rear anchor system 4, a running system, a closed protection system, a bottom mold platform, and a drainage system, an anti-electric device, an inner mold and a support 6.

[0025] like Figures 1 to 4 As shown, the load-bearing device includes the main girder 1 and the connecting system 2 of the main girder 1, and the connecting system 2 connects the constituent girders of the main girder 1 into a whole.

[0026] The hanging system is used to hoist the part below the beam surface on the load-bearing device, including the front upper beam 301, the front sling 302, the front sling 303, the rear sling 304, and the rear sling 305. The lower ends of the above slings are all fixed to the base form platform The upper ends of the front slings 302, 303 are fixed on the front upper beam 301, the front upper beam 301 is fixed on th...

Abstract

The invention discloses a totally enclosed cradle and a construction method for suspending cast of concrete by using the same. The cradle comprises a walking system and an anchoring system. The walking system is in traction connection with a bearing device of a bottom die platform which is connected on the bearing device and the cast box girder through a hanger system. A closed protective system is arranged along the periphery of the bottom die platform. The anchoring system anchors the bearing device on the cast box girder. The closed protective system comprises a cradle top cover and a protective structure at the periphery of the cradle. The closed protective system and the bottom die platform surround a totally closed construction space. The structure seals the cast-in-place concrete in construction inside with effect of nourishing the indoor concrete and avoiding fear of heights of operating personnel. The construction method realizes splicing, forward walk and anchoring and retreat of the cradle simply and conveniently, and is suitable for occasions where the cradle cannot be dismounted above because high speed road, rail way line and the like are below.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a fully enclosed hanging basket and a construction method for hanging concrete by using the hanging basket. Background technique [0002] The bridge construction hanging basket is a kind of equipment used for concrete bridge cantilever casting. The construction hanging baskets used in the cantilevered construction of prestressed concrete continuous beams (rigid frame beams) in my country mostly adopt functional designs, as long as they meet the structural strength, stiffness, stability, and self-weight restrictions. It is an open hanging basket, and the safety protection is only limited to conventional guardrails, protective nets, and the removal of the hanging basket requires an overall dismantling on the spot. Considering the requirements of safety, environmental protection and standardized construction, the semi-enclosed hanging basket came into being. Chinese patent 20072...
