Prestress joint production line for producing concrete slabs and concrete beams

Abstract

The invention relates to a prestress joint production line for producing concrete slabs and concrete beams. The prestress joint production line comprises a working platform and is characterized in that the working platform comprises a base frame formed by concrete longitudinal beams and concrete crossbeams, embedded steel plates are fixedly connected into the concrete longitudinal beams, embeddedsteel beams are fixedly connected into the concrete crossbeams, a steel framework is welded to the base frame, the steal framework is submerged in concrete to form a platform through pouring, concretepiers are arranged on the ground at two ends of the concrete longitudinal beams, anchoring steel retaining plates are fixedly connected into the concrete piers, the concrete piers, the concrete longitudinal beams and the concrete crossbeams are integrally formed through pouring, each anchoring steel retaining plate is provided with a tensioning mechanism, and frame moulds for producing the concrete slabs and the concrete beams are arranged on the platform. Due to the fact that the steel framework, the embedded steel plates and the embedded steel beams are integrally welded and the concrete longitudinal beams, the concrete crossbeams and the concrete piers are integrally formed through forming, the overall strength of the working platform is guaranteed, and the joint production of the concrete slabs and concrete beams can be performed effectively.

Description

technical field [0001] The invention relates to the technical field of production of concrete slabs and concrete beams, in particular to a prestressed collinear production line for producing concrete slabs and concrete beams. Background technique [0002] With the progress of society, the construction industry has developed rapidly, and the market has a strong demand for SP panels, double T panels, laminated panels, wall panels and composite beams of concrete structures, and currently used for SP panels, double T panels, and laminated panels The production line of wall panels and composite beams is in the shape of a long strip. Its structure includes two concrete buttresses set under the ground at intervals, and concrete piles driven into the ground are arranged at intervals between the two concrete buttresses. A horizontal platform for processing concrete slabs and concrete beams is provided above the piles. Its shortcoming is that: since concrete slabs and concrete beams ...

AI Technical Summary

Problems solved by technology

Its shortcoming is that: since concrete slabs and concrete beams need to be prestressed during the production process, the tensioning mechanism used to add prestressing is based on the concrete pier as the fulcrum. When the tensioning mechanism is working, it will give the corresponding concrete pier A reaction force, so the concrete pier bears the shear force in the horizontal direction. Because the nature of the concrete is able to withstand high-strength pressure, but cannot withstand high-strength shear force, the concrete pier is easy to fatigue ...
