PPVC modular building structure system and assembly method thereof

A technology of building structure and assembly method, which is applied in the direction of building components, building structure, construction, etc., can solve the problem of tensile resistance, pull resistance, shear resistance, pull resistance, and bending resistance, which affect a wide range of PPVC modular buildings. The use and connection points do not take into account the seismic performance of the structure, etc., to achieve the effect of shortening the construction period, good application prospects, and increasing the tensile strength

Problems solved by technology

[0008] However, the connection points of this modular assembly structure do not take into account the seismic performance of the structure, and the tension, pull, shear, pull, and bending resistance between individual modules are less considered, which is not very suitable for our country. Earthquake environment, in addition, the cost of PPVC modular buildings is relatively high, these two defects have affected the large-scale use of PPVC modular buildings in China

Embodiment 1

[0044] Such as Figure 1 to Figure 8 As shown, a PPVC modular building structure system according to the present invention, the structure system is composed of several identical modules 1, each module 1 includes an upper floor 11, a lower floor 12, several wall panels 13 and several columns 14. The wallboards 13 are arranged at intervals, and columns 14 are arranged between the adjacent wallboards 13, and the sides of the wallboards 13 are fixedly connected to the side walls of the columns 14 (it can be bolted or tenoned) connection), the upper floor 11 covers the top of the module 1, and the lower floor 12 covers the bottom of the module 1, and the lower floor 12 includes a prefabricated slab 121 and a cast-in-place slab 122 that cooperate with each other, and the prefabricated slab 121 and the cast-in-place slab 122 are interlocking tooth-like structures, and the areas of the prefabricated slab 121 and the cast-in-place slab 122 can each account for half; The all-cast-in-pl...

Abstract

The invention belongs to the technical field of civil engineering assembly, and particularly relates to a PPVC modular building structure system and an assembly method thereof. According to the structure system, integral anti-seismic property of a structure is taken into account, and through arrangement of a shear key A and a shear key B, tensile property and shear resistance among modules are improved; and steel bonding treatment is carried out on wallboards around a stand column and the shear keys B, so that tensile property and bending resistance of the structure are further improved. Due to the fact that a lower floor slab adopts a structure that a prefabricated slab meshes with a cast-in-place slab tooth-shaped structure, overall stability of the lower floor slab is improved; meanwhile, compared with the mode that the whole lower floor slab is cast in place in the prior art, influence of site construction on an environment is reduced, the overall assembly efficiency of the structure system is improved, and the construction period is shortened; and compared with the condition that the whole lower floor slab is prefabricated in the prior art, the cost is reduced, and the integrity of the whole lower floor slab becomes better through adopting an occlusion form of the tooth-shaped structure.

Description

technical field [0001] The invention belongs to the technical field of civil engineering assembly, and in particular relates to a PPVC modular building structure system and an assembly method thereof. Background technique [0002] PPVC (Prefabricated Prefinished Volumetric Construction), also known as prefabricated pre-decorated modular building, is to process the entire room of the building as a modular unit in a prefabricated factory, complete the structure and decoration (including floors, walls, window frames, ceilings, etc.) and After forming an independent module, it is a construction technology that is sent to the construction site for on-site hoisting. In 2016, Singapore began to implement PPVC construction. At present, thousands of housing units in many projects are being constructed using PPVC technology. HDB is expected to make PPVC prefabricated construction technology mandatory in 40% of construction projects by 2020. According to the statistics of the Housin...
