Fabricated box culvert vertical prefabricated light formwork and manufacturing method thereof, and box culvert prefabricating method

Abstract

The invention discloses a fabricated box culvert vertical prefabricated light formwork and a manufacturing method thereof, and a box culvert prefabricating method. The fabricated box culvert vertical prefabricated light formwork comprises a base, an outer formwork body, a connecting rod mechanism, an inner formwork body, an end formwork body and a hydraulic supporting mechanism; the base is composed of two longitudinal beams, three cross beams and two walking platforms, the outer formwork body is composed of four integral formwork plates, a steel plate is attached to the interior of each formwork plate, inclined struts are welded to the exterior of each formwork plate, the inner formwork body is composed of an inner-layer grid rib plate and an outer-layer inner formwork steel plate, each inner formwork steel plate is formed by stamping a whole steel plate, only one abutted seam is formed in the whole section, two longitudinal ribs are arranged at the abutted seam of the folded section, walking wheels are arranged at the lower ends of the longitudinal ribs, and the inner formwork body is assembled and disassembled through stretching and retracting of the hydraulic supporting mechanism. The outer formwork body adopts an integral and large-block formwork plate design and can be driven by the connecting rod mechanism or the hydraulic system, the inner formwork body is driven by a full-hydraulic support, only one abutted seam is formed in the whole section, vertical pouring and end plate matching production are adopted, and the appearance effect of a segment finished product is good.

Description

Technical field: [0001] The invention relates to a civil engineering technology, in particular to an assembled box culvert vertical prefabricated light formwork, a manufacturing method thereof and a box culvert prefabrication method. Background technique: [0002] As prefabricated box culverts are increasingly widely used in roads, railways, municipal and other fields, their mechanization, high degree of industrialization, little impact on climate, short construction period, easy prefabrication, safe and fast installation, and reliable quality have been adopted by many Well-known in the field, it has become the first choice for program comparison in related industries and has a good development prospect. [0003] In practical application, after many observations and analysis, it is found that there are still some deficiencies in the prefabricated box culvert. For example, in areas with high earthquake resistance and weak foundations, prefabricated box culverts are usually d...

Problems solved by technology

For the section with a large span (L≥3m), when the horizontal construction is adopted, it cannot be poured as a whole, and the bottom plate must be poured first, so that the bottom plate of the inner mold must be made movable (lifting or side shifting), which increases the cost of splicing. joints, installation is difficult, pouring is relatively difficult, and the appearance effect is not ideal
