A composite prefabricated floor slab for a low-rise prefabricated steel structure residence

Abstract

The invention discloses a combined prefabricated floor slab for a low-rise assembled steel structure residence, which belongs to the technical field of construction. It is a combined prefabricated floor slab for a low-rise assembled steel structure residence, which can realize the rapid connection of the prefabricated slab through connecting parts, and the technicians can wirelessly connect the prefabricated floor slab. The signal starts the rotating magnetic field to drive the installation action of the magnetic bolts to realize the seamless assembly between the prefabricated panels, and the prestressed steel bars pre-implanted inside the prefabricated panels realize high-strength expansion under the two-way memory effect of the shape memory alloy Connection, and then complete the transfer and sharing of prestress, improve the assembly strength between prefabricated panels, and at the same time use wireless signals to complete the disassembly during recycling, basically realize the non-destructive recycling of prefabricated panels, can realize direct secondary utilization, and significantly improve assembly While reducing construction costs while improving efficiency, it is in line with the green environmental protection concept of sustainable development in today's society.

Description

technical field [0001] The invention relates to the technical field of construction, and more specifically relates to a combined prefabricated floor slab for a low-rise assembled steel structure residence. Background technique [0002] Steel structure residence refers to the residential building that uses steel as the load-bearing beam and column of the building. Its advantages are: 1. Light weight and high strength. The weight of a residence built with steel structure is about 1 / 2 of that of a reinforced concrete residence; The use area is about 4% higher than that of reinforced concrete houses. 2. Safety and reliability, good performance in earthquake resistance and wind resistance. 3. The steel structural components are manufactured in the factory, which reduces the workload on site, shortens the construction period, and meets the requirements of industrialization. 4. The quality of the steel structure factory is reliable, the size is accurate, the installation is conve...

Problems solved by technology

[0012] However, there are currently many temporary low-rise steel structure houses in our country, such as the Olympic Village at that time and some temporary housing needs. Generally, operating efficiency and cost are taken as the preferred options, so low-rise prefabricated steel structure houses are very suitable, but prefabricated panels are in After being transported to the construction site, in order to pursue the connection strength, most of them are permanently assembled. For example, post-cast concrete belts are used for connection. Later, when they are disassembled, they can only be forcibly pulled down and difficult to recycle as a whole. They cannot be used directly for secondary use, resulting in waste of resources. Does not conform to the sustainable development concept of environmental protection in today's society
