Problems solved by technology

During construction and hoisting, the tendons of the prefabricated laminated slabs often interfere with the beam gluten and stirrups, which affects the progress of the hoisting. In order to enable the prefabricated laminated slabs to be hoisted in, the curved beam stirrups are often broken, which affects the quality of the project

Abstract

The invention discloses a non-stretching bar combined laminated slab with prefabricated prestressed concrete ribs. The non-stretching bar combined laminated slab comprises a bottom plate (1), longitudinal bars (2) and transverse bars (3) are arranged in the bottom plate (1), a plurality of concrete ribs (4) are arranged on the bottom plate (1), the concrete ribs (4) are arranged in the direction of the longitudinal bars (2), a plurality of stirrups (5) are arranged in the concrete ribs (4), and the bottoms of the stirrups (5) are fixedly arranged on the transverse bars (3). According to the scheme of the non-stretching bar combined laminated slab with the prefabricated prestressed concrete ribs, the span of the bottom plate can be increased, and the production process is simplified.

Description

technical field [0001] The invention relates to a prefabricated floor slab, in particular to a composite laminated slab with prefabricated prestressed concrete ribs without stretching reinforcement. Background technique [0002] In prefabricated buildings, there are currently several mainstream prefabricated laminated panels. For example, the maximum span of prefabricated truss reinforced laminated panels generally does not exceed 6m. At present, the mainstream is to increase the span of the prefabricated floor by applying prestress to the prefabricated floor. The prefabricated prestressed floor is produced by long-line mold tires. Generally, the length of the long-line tire membrane reaches more than 100m, and multiple prestressed tendons are stretched at the same time. Due to the production process, the prestressed tendons are not stretched uniformly, resulting in uneven warping deformation of the prefabricated floor, which seriously affects the quality of the project. ...
