Primary and secondary module unit combination structure of high-rise module building space and connection method thereof

Abstract

The invention discloses a primary and secondary module unit combination structure of high-rise module building space. The structure comprises main module units and secondary module units which are scientifically combined on the plane and in the space to form an integral combination structure system. The main module units are main weight bearing structures and bear the weight of the main module units and the secondary module units, a lateral force resistance support structure is arranged each the main module unit, and an effect of effectively resisting wind and earthquakes is achieved. The secondary module units only bear self weight and transfer vertical force and horizontal action to the main module units through relative connection. The secondary module units are often arranged between the main module units, connection node plates are reserved on main module unit frame columns, every two main modules are connected through a connection steel beam, the connection steel beams and the like are utilized as an operation platform to weld frame columns of the main module units on two sides into a whole, then the secondary module units are arranged on the connection steel beams, and the secondary module units can be arranged every two layers or layer by layer to form the integral structure with the main module units.

Description

technical field [0001] The invention relates to a building structure system, in particular to a space combination structure of primary and secondary modules in a modular building. Background technique [0002] Modular building is a new type of building structure system, which can be widely used in residential buildings, office buildings, teaching buildings and other buildings. The modular unit is generally made of steel structure, and the steel can be recycled and used to achieve green environmental protection. The module production and equipment installation account for 90% of the total construction work, and they are all completed on the factory assembly line. The degree of mechanization and industrialization is high, and the production efficiency is greatly improved. Labor costs are greatly reduced, and the production environment for workers is greatly improved. Most of the traditional housing construction adopts cast-in-place reinforced concrete structure and masonry st...

AI Technical Summary

Problems solved by technology

[0005] 1. The frame column connection of the upper and lower module units generally adopts a long steel rod (rebar) inside the frame column to resist the overturning moment of the lateral action (wind and earthquake), but the connection node of the upper and lower frame columns is hinged. Rigid joints cannot be formed, which does not meet the regulations on rigid joints in my country's "Code for Seismic Design of Buildings" GB50011-2010

[0006] 2. The frame column connection of the left and right module units is generally connected by a horizontal steel plate, which can only transmit horizontal tension and a certain shear force, but cannot transmit bending moment

[0007] 3. Others use lap plate bolts to connect one exposed side of the module unit, and the other sides are not connected, which cannot meet the requirement that the steel frame columns should be continuous and equal in strength

[0008] 4. In addition, there is a method of fixing double-tensioned steel rods between frame columns and frame beams and auxiliary oblique angle bracing, and the joint structure is complex

[0009] Most of my country's urban and rural areas are located in earthquake zones, and most of them are high-rise (including high-rise) residences and apartments, which have high requirements for seismic performance. Therefore, the connection nodes used in the current modular building structures do not comply with my country's "Code for Seismic Design of Buildings" GB50011-2010 Design requirements for connection nodes, and poor technical reliability, it is not safe to apply in seismic areas
