Combined prefabricated floor slab for low-rise prefabricated steel structure dwellings

Abstract

The invention discloses a combined prefabricated floor slab for low-rise prefabricated steel structure dwellings, and belongs to the field of construction technology. The combined prefabricated floorslab for the low-rise prefabricated steel structure dwellings can quickly connect prefabricated slabs through connecting parts, and technicians initiates a rotating magnetic field in a wireless signalmode to drive the installation action of magnetic bolts to achieve seamless assembling between the prefabricated slabs, with pre-embedded prestressed steel bars in the prefabricated slabs, under thetwo-way memory effect of shape memory alloy, and the high-strength expansion connection is realized, so that the transmission and sharing of prestress are completed, the assembling strength between the prefabricated slabs is improved, the wireless signal is used for completing the disassembling during recycling, non-destructive recycling of the prefabricated slabs is basically achieved, direct secondary utilization can be achieved, and assembling efficiency is significantly improved while the construction cost is reduced, and the combined prefabricated floor slab for the low-rise prefabricatedsteel structure dwellings is in line with the green environmental protection concept of sustainable development in nowadays 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
