Abstract

The invention belongs to the technical field of bridge construction, relates to a cast-in-situ construction facility of a 900t box beam of a high-speed railway, and in particular relates to a movable mould frame capable of efficiently and quickly constructing a large box beam. The movable mould frame comprises a front support system, a rear support system, a transverse moving system, a longitudinal through-hole walking system, a forming main beam structure, a prefabricated rebar hoisting die entering system, a bottom die, a bottom die support system, an inner membrane, an inner membrane support system, a quick maintenance system, a front cross beam system and a rear cross beam system. The movable mould frame provided by the invention has novel design and a reasonable structure, parallel construction of the movable mould frame splicing and box beam rebar binding is realized, and the construction period is shortened; the movable mould frame is in a constant-temperature state in the maintenance period, the temperature difference between the inner environment and outer environment is controlled below 15 DEG C, the maintenance lasts for 24 hours, and the beam strength can reach 75% of the designed strength or higher; the mechanization degree is high, the time is saved, and the cost is lowered; and the system units are scientifically and reasonably divided, the mechanical property is good, the assembly/disassembly and transport are convenient, the stability is high, and the construction efficiency can reach 4-5 days per hole.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and relates to an in-situ cast-in-place construction facility for a 900t box girder of a high-speed railway, which can efficiently and quickly construct a shifting formwork for a large box girder. Background technique [0002] According to the position of the traveling mechanism, the mobile formwork can be divided into two types: upward type and downward type. The traveling mechanism of the upward mobile formwork is above the box girder, the main structure is above the pier, the main girder structure is supported on the pier top and the formed girder body, and the formwork system is suspended on the formed main girder structure through cantilever beams, booms and suspenders. Below, adjust the pre-camber of the formwork by using the adjustable struts, adjust the linear elevation of the beam bottom according to the design requirements; It is connected with the formed main beam structur...
