Problems solved by technology

[0002]At this stage, the country vigorously develops housing industrialization, but in the existing prefabricated building methods, prefabricated beams are limited by beam length, production environment, transportation and installation conditions, etc.
As a result, the beam is prefabricated in sections, and the main reinforcement of the beam is pre-embedded in the precast concrete, and the position is fixed and cannot be rotated. As a result, the traditional connection method of the main reinforcement of the beam cannot be applied. There are few connection methods, the connection is difficult, and the connection quality is not easy to guarantee. The process is complicated, which restricts the development of housing industrialization

Embodiment 1

[0033] A double-sided composite beam, which consists of: a steel frame 6, a precast concrete slab 1, the vertical sides of the steel frame are poured with the precast concrete slab, the steel frame includes truss bars 4, the A group of beam stirrups 2 are installed in the truss bars, the vertical edges on both sides of a group of beam stirrups are fixed with the truss bars, and the vertical edges on both sides of a group of beam stirrups are fixed with a group of structural steel bars. 3 is fixed, a set of beam stirrups are respectively pierced with beam main bars 5 at the four corner arc positions, and the inner side of the precast concrete slab has a smoothly reduced cross-section.

Embodiment 2

[0035] In the double-sided laminated beam described in Embodiment 1, a group of beam stirrups are arranged in parallel, and the beam stirrups are closed loops connected by butt welding or bent at the ends into 135-degree hooks The above-mentioned hook forms a closed loop or a long and one short U-shape, and the double-sided composite beam is used for setting the insulation layer on the surface of the prefabricated concrete slab on the outdoor side or setting the insulation layer and decoration at the same time. layer.

Embodiment 3

[0037] A construction method of a double-sided composite beam, the method is first of all according to the actual use position of the double-sided composite beam, reserve installation space for the floor slab on the upper or lower part of the precast concrete slabs on both sides, and install the double-sided composite beam The surface of the prefabricated concrete slab used on the outdoor side is provided with an insulation layer or an insulation layer and a decorative layer at the same time. After the double-sided laminated beam is manufactured according to the requirements, it is transported to the construction site, and the installation conditions are met, and the support is set and fixed. Bottom formwork, hoisting double-sided laminated beams, adjusting its position and elevation, tying the beam main reinforcement, after the beam main reinforcement is bound, bending the beam stirrup into a closed ring shape, and the beam main reinforcement passes through the Welding connect...

Abstract

The invention relates to a double-faced superposed beam and a construction method thereof. At the present stage, the state energetically develops housing industrialization, but in an existing prefabricated building mode, a prefabricated beam is limited by the beam length, a production environment, transportation and installation conditions and the like. The double-faced superposed beam comprises a steel bar framework (6) and prefabricated concrete slabs (1), the prefabricated concrete slabs are poured on the two vertical sides of the steel bar framework, the steel bar framework comprises truss bars (4), a set of beam stirrups (2) are installed in the truss bars, the two vertical sides of the one set of beam stirrups are fixed with the truss bars, the two vertical sides of the one set of beam stirrups are fixed with a set of constructional steel bars (3), beam main bars (5) are arranged at the circular arc positions of four corners of the one set of beam stirrups in a penetrating mode respectively, and the inner sides of the prefabricated concrete slabs are provided with smoothly-reduced cross sections.

Description

Technical field: [0001] The invention relates to a double-sided composite beam and a construction method thereof. Background technique: [0002] At this stage, the country is vigorously developing housing industrialization, but in the existing prefabricated building methods, prefabricated beams are limited by beam length, production environment, transportation and installation conditions. As a result, the beam is prefabricated in sections, and the main reinforcement of the beam is pre-embedded in the precast concrete, and the position is fixed and cannot be rotated. As a result, the traditional connection method of the main reinforcement of the beam cannot be applied. There are few connection methods, the connection is difficult, and the connection quality is not easy to guarantee. belt, the process is complicated, which restricts the development of housing industrialization.
