Problems solved by technology

The construction method is more environmentally friendly, and the construction site can realize the advantages of no dust, no waste, no construction measures and auxiliary materials, and no noise; Beams and other supporting reinforcement forms) or support first and then excavate (such as ground connection wall, cast-in-situ pile support form), the traditional technology has a long construction period and a large waste of materials. For example, the ground connection wall is used outside the underground space When there are internal bottom beams and interstory beam embedded parts in the wall, the concrete surface needs to be manually removed in the later stage, and even the embedded parts connected to the ground wall can not be used, and secondary drilling and rebar planting are required to complete the reinforced connection. The combination of "U" type caisson first section + "H" type laminated outer leaf wall panel + inner leaf cast-in-place concrete realizes the completion of beams, columns, floors, stairs, Standardized design, factory production and assembly construction of exterior walls and interior walls

Abstract

The invention relates to a prefabricated and assembled integral structure for underground space and its construction method, comprising a "U"-shaped first caisson, an "H"-shaped standard section arranged on the upper part of the "U"-shaped first caisson, and a "U"-shaped caisson. The gusset device inside the "U"-shaped first caisson, the "U"-shaped first caisson includes several "U"-shaped caisson components, iron blade feet and threaded steel bars arranged inside the "U"-shaped caisson components Inserting ribs and horizontal connecting devices, vertically connecting reinforcing steel bars arranged on the top of the "U"-shaped caisson member, and grouting holes for connecting steel bars are opened on the top surface of the "U"-shaped caisson member; the "H"-shaped standard section Including the "H" type laminated wall panels fixed on the top of the "U" type caisson components, the steel trusses arranged inside the "H" type laminated wall panels, the fixing Connectors and telescopic fixing devices, and the side walls at both ends of the "H" type laminated wall panels are respectively provided with shear keys and shear grooves.

Description

technical field [0001] The invention relates to an underground space prefabricated assembly integral structure and a construction method thereof, which are applied in the technical field of underground space prefabricated assembly. Background technique [0002] The industrialization of construction is based on the prefabricated production of components and prefabricated construction as the main production methods, and is characterized by standardization of design, component parts, construction mechanization, and management informationization, and can integrate the entire construction industry such as design, production, and construction. Chain, a new production activity mode that realizes the sustainable and circular development of low-carbon, energy-saving, environmentally friendly construction products, and maximizes the life cycle value of construction products. Transitioning the traditional scattered and messy manual operation method to the industrial standardized produc...
