Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] as attached figure 1 As shown, the assembled large module laminated beam-slab structure with three-dimensional truss temporary support is composed of temporary truss supports, steel beams, laminated floor slabs, steel mesh, and connecting plates; the assembled large modules are laminated The basic components of the floor structure include side-span unit A and mid-span unit B; the side spans at both ends of the prefabricated floor structure are side-span unit A, and the mid-span unit connected to side-span unit A B, the other mid-span units all use mid-span board unit B and are spliced ​​together.

[0027] The longitudinal girders of the prefabricated laminated floor structure all adopt longitudinal I-shaped cross-section girders (3). The transverse beam on one side of the end of the floor in the side-span slab unit A adopts a transverse side-span I-shaped cr...

Abstract

The invention discloses an assembly type big module overlapped beam and slab structure with three-dimensional truss temporary supports. A temporary whole is formed by connecting quadrangular three-dimensional truss temporary supports and beams through connecting plates and bolts. A reinforcing mesh is paved on the temporary supports, a prefabricated concrete layer is poured after the reinforcing mesh is paved, and a whole is formed by pouring concrete at the inner sides of flanges of the beams during pouring. The assembly type big module overlapped beam and slab structure with the three-dimensional truss temporary supports is hoisted in place after prefabrication and processing, an overlapped slab is formed by paving a slab upper layer reinforcing mesh piece on the upper part of the prefabricated concrete layer according to the design and pouring the rest of slab concrete. When the slab maintenance is finished, the bolts are disassembled, the temporary supports are removed, and the assembly type overlapped slab construction is completed. The assembly type big module overlapped beam and slab structure with the three-dimensional truss temporary supports can solve the problem of slabintegrity, lifting weight is reduced, and the assembly accuracy and construction efficiency are improved.

Description

technical field [0001] The invention relates to an assembled large module laminated beam-slab structure with a three-dimensional truss temporary support, belonging to the technical field of structural engineering. Background technique [0002] Prefabricated buildings are the focus of development in the construction industry for a period of time in the future, and the innovation of industrialized prefabricated structural systems is imperative. The prefabricated structural system refers to the building produced by making housing units or components according to uniform and standard building part specifications, and then transporting them to the construction site for assembly in place. A large number of building parts are produced and processed by the workshop, a large number of assembly operations on site, standardization of design and informatization of management meet the requirements of green buildings. It is characterized by light building weight, energy saving and enviro...
