Hanging basket for cantilever beam construction

Abstract

The invention discloses a hanging basket for cantilever beam construction, which is characterized in that a main framework and a template support system are connected by a connecting system taking a hanging belt as a main part, the main framework comprises two triangular trusses and a connecting system, and a front upper cross beam, two ends of a gantry and the front upper cross beam are fixedly connected to two triangular trusses, and hanging basket walking and anchoring systems are respectively arranged at the bottoms of the two triangular trusses; a lifting belt system comprises an inner mold walking beam lifting belt, a walking trolley and a second lifting ring; an inner template is supported by an inner template walking beam; and two ends of the inner template walking beam are sleeved with second lifting rings, the second lifting ring at one end is connected to the surface of a formed beam section in a lifting mode through an inner mold walking beam lifting belt, the second lifting ring at the other end is connected to the front upper cross beam in a lifting mode, and the walking trolley is in contact connection with the surface of the inner template walking beam and is in rolling connection with the inner template walking beam. The whole system of the hanging basket is simple in structure and convenient to disassemble and assemble, the inner template can be integrally pulled through the walking trolley, the construction progress is accelerated, and the problem that the construction progress is affected due to complexity of the hanging basket in small cantilever beam construction is solved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and more specifically relates to a hanging basket for cantilever beam construction. Background technique [0002] The hanging basket is the main equipment in the bridge cantilever construction process. The commonly used hanging basket structures include the upper bearing triangular hanging basket, the rhombus hanging basket, the truss type, the cable-stayed type and the hybrid hanging basket. From the perspective of the force structure, the cable-stayed The hanging basket is more scientific, but the cable-stayed hanging basket has high requirements for construction, and the horizontal component force of the inclined-stay rod is not easy to handle, and it has to pass through the wing plate and the roof concrete, which is troublesome to disassemble and inconvenient to move the hanging basket; the triangular hanging basket is affected by The force is relatively clear, but it is not suita...

AI Technical Summary

Problems solved by technology

[0003] The existing technology mainly has the following defects: (1) The main load-bearing structure is complex, there are many connection points, and the operation is complicated during the moving process. The construction efficiency of small cantilever beams is low, which is not conducive to speeding up the construction progress; (2) The truss-type hanging basket is a commonly used structural form. This kind of hanging basket is set on the top of the beam body. There are many embedded parts in this kind of hanging basket. , the construction is difficult and affects the construction period of the entire bridge construction
