Hanging basket for cantilever casting of small-curvature-radius continuous beam

Abstract

The invention discloses a hanging basket for cantilever casting of a small-curvature-radius continuous beam. The hanging basket comprises a main framework and a traveling system. The main framework comprises two triangular main trusses; each main truss is composed of a truss main beam, a vertical rod, a front inclined rod and a rear inclined rod; the front end, the middle part and the rear end ofeach truss main beam are connected with the front end of the corresponding front inclined rod, the lower end of the corresponding vertical rod and the rear end of the corresponding rear inclined rod through a front node seat, a middle fulcrum seat and a rear anchor seat respectively; the upper end of each vertical rod is connected with the rear end of the corresponding front inclined rod and the front end of the corresponding rear inclined rod through top node seats separately; the traveling system comprises two traveling rails, a sliding mechanism and a traveling mechanism; the sliding mechanism comprises two front sliding seats which are mounted between the two traveling rails and the middle fulcrum seats of the two main trusses separately; and the traveling mechanism comprises two reverse buckling wheel traveling devices which are installed between the two traveling rails and the rear anchor seats of the two main trusses separately. According to the hanging basket, the effects of horizontal rotation of the hanging basket around the front sliding seats, the lateral offset of the hanging basket and the advancing of the traveling rails are realized.

Description

technical field [0001] The invention relates to a hanging basket for cantilever casting continuous beams with small curvature radius. Background technique [0002] In the cantilever pouring construction of the concrete continuous box girder of ordinary bridges with hanging baskets, since the direction of the box girder is straight, the cross slope of the box girder is generally about 0.02%, and it is symmetrical and fixed. Therefore, ordinary hanging baskets can be constructed smoothly as long as the walking track is flattened by steel pillows. [0003] However, the structure of the concrete continuous box girder of the DASH expressway ramp in Malaysia is completely different. The pouring beam section is 4.34 meters long, and the box girder section 0 is 12 meters long. The beam bottom plate changes according to the parabola. The beam height at the root of the 0# box girder is 5.0 meters, and the beam height at the side support point is 2.5 meters. The direction of the box...

Problems solved by technology

[0009] The purpose of the present invention is to overcome the defects of the prior art and provide a hanging basket for cantilever casting of continuous beams with small curvature radius, which solves the problem that the hanging basket can rotate horizontally around the front sliding seat, the lateral deviation of the hanging basket and the The problem of the forward movement of the walking track; it can be used not only for the construction of conventional large-span cast-in-place continuous beam structures, but also for the construction of any one-way ultra-high balance, arc-turned large-span cast-in-place continuous beams, and has a wider scope of application
