Embodiment Construction

[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] In the small quasi-frame structure of the large-span prestressed concrete slab provided by the present invention, transverse erecting steel bars are arranged on the prestressed concrete beam slabs close to both sides of the frame column, and the virtual beam is located in the middle of the two prestressed beam slabs on both sides of the frame column Between the frame column and the frame column at the other end, the longitudinal reinforcement of the virtual beam is connected with the frame column reinforcement at both ends, and the upper part of the longitudinal reinforcement is connected with the horizontal erecting bar or mesh connecting the prestressed concrete beam slab on both sides of the frame column.

[0026] Another solution is to open a hole in the side of the beam plate on both sides of the frame column, and erect a horizontal erectio...

Abstract

The invention belongs to the technical field of construction engineering structures and particularly relates to a virtual beam of a large-span prestressed concrete plate. After frame columns and frame longitudinal beams are installed, a cross constructed erection rebar is arranged on the upper surface of prestressed double T plates or a single prstressed T plate or a hollow plate or an SP plate or a large-span prestressed concrete channel plate or a concrete rectangular beam comprising a hollow rectangular beam plate or a large-span prestressed concrete multiple T-shaped beam plate which are installed close to two sides of the frame columns. The middle portion of two prestressed beam plates on two sides of the frame column and the frame columns are connected with the middle portion of a frame column at the other end, a longitudinal rebar of the virtual beam is in rebar connection with the frame columns at two ends, and the longitudinal rebar is connected with a cross erection rebar or a mesh sheet on the surface of the prestressed concrete beam plate on two sides of the frame columns; the virtual beam is connected through a rebar, and a concrete cast-in-place layer is arranged on the virtual beam. The novel virtual beam achieves using the large-span prestressed concrete plate in a frame structure and can be manufactured in various modes.

Description

technical field [0001] The invention belongs to the technical field of construction engineering structures, and in particular relates to a virtual beam used in a large-span prestressed concrete beam-slab frame structure. Background technique [0002] Large-span prestressed concrete beams and slabs [including double T slabs, channel slabs, single T slabs, multi-T box beams, etc. (hereinafter referred to as T-shaped slabs) and hollow slabs (hereinafter referred to as SP slabs)] belong to high-strength concrete thin-walled components (especially the former), its biggest advantage is: large span, large column distance and large span structure can be built; low sagittal height (0.45~1.085m, about 1 / 4~ 1 / 3), can significantly reduce the height of buildings, achieve the effect of material and energy saving; good stability, without additional lateral support; large component coverage, high installation efficiency, become the most advantageous building roof to replace the traditional...
