STRUCTURE AND CONSTRUCTION METHOD
TECHNICAL FIELD
The present disclosure relates to a technical field of pre- fabricated buildings, and more particularly to a prefabricated steel frame embedded vertical hidden joint wallboard structure and a construction method.
BACKGROUND ART
As an important part of the building, steel structures are in line with the goals of industrialization and rapid construction of buildings. It is an important part for the transformation and up- grading of Chinese construction industry to vigorously develop steel structure buildings and promote the development of the pre- fabricated steel structure building systems. Steel frame structure is the main construction system. Due to the constraints of materi- al properties and cross-sectional characteristics, steel frame structure has weak lateral force resistance, so how to improve the lateral stiffness and seismic performance of steel frame under economic and effective constraints is a technical challenge that restricts the applications of the high-rise steel structures.
Steel frame structure is one of the main presentation methods of prefabricated buildings, and its connection compatibility with the maintenance components, especially the structure and the wall, and the common quality problems has always been a bottleneck con- straint that affects the vigorous development of prefabricated buildings. The use of concrete shear wall structure can effective- ly improve the lateral stiffness of the structure. However, tradi- tional wet construction has the drawbacks of extensive construc- tion, high labor intensity, and long working cycle and serious en- vironmental pollutions in terms of the steel binding and installa- tion, formwork making and installation, dismantling, and concrete pouring and maintenance, etc., which is inconsistent with the de- velopment path of assembly.
If the prefabricated steel frame is filled with the wall, es- pecially the embedded prefabricated filling wall, the wallboard will bear horizontal force through the connecting structure, and it is necessary to solve the rapid connecting technology of steel and concrete components, the interface connecting technology of prefabricated concrete and peripheral beam columns, the cracking problem caused by different materials of the steel structure and the interface components, the fireproof problem, etc. The current- ly-issued Technical Regulations for Prefabricated Concrete Struc- tures JGJ1-2014, Technical standard for assembled buildings with concrete structure GB/T51231-2016, Assembled Concrete Connection
Joint Construction 15G310-12, Technical Specification for Prefab- ricated Steel Structure Buildings (JGJ469-2019), etc. do not have related joint structure methods and construction technologies and do not have standards and technical standards which can be re- ferred to.
In order to vigorously develop the prefabricated steel struc- ture buildings, it is urgently needed to develop an filling wall that matches with the prefabricated steel frame structure and meets the structure, construction, energy conservation and other elements, especially to solve the technical problems in the as- pects of the structure, process, construction method, etc. of the infill wall that adapt to the building industrialization develop- ment, so as to promote healthy and orderly development of the pre- fabricated steel frame structure.
