Description
Technical Field
The utility model belongs to the technical field of structural engineering, in particular to vertical intermediate layer rubber pad connected node that sets up of assembled concrete shear wall structure and construction method thereof.
Background
With the rapid development of economy in China, the living standard of people is continuously improved, and the requirements on houses are increasingly improved. Meanwhile, the cast-in-place construction mode of the house is not suitable for the sustainable development concept of China. At present, China urgently needs to solve the problems of high energy consumption, high pollution, high investment and the like in residential construction, so the urban and rural construction department of China developing and reforming the commission houses issues a green building action scheme, wherein the building systems such as prefabricated concrete structures, steel structures and the like suitable for industrial production are definitely promoted, the prefabrication and assembly technologies of construction projects are accelerated to be developed, and the building industrial technology integration level is improved.

(2) The construction period is short. Because a large amount of fabricated concrete members are produced and maintained in a factory, the work carried out on a construction site is only to hoist, assemble and reinforce nodes of the members prefabricated by a prefabrication factory, a scaffold and a support do not need to be installed, the influence of seasonal factors on the construction period is reduced, the work of decoration, hydropower construction and the like is carried out after the main body structure is formed, the workload is far less than that of construction by a cast-in-place method, and the working procedures of masonry and plastering are even omitted, so that the whole construction period is greatly shortened.
(3) The quality of the component is good. The concrete in the prefabrication plant does not need pumping, the water in the concrete is less, and the strength grade of the concrete is higher than that of cast-in-place concrete. After the components are poured in the prefabrication factory, the components are subjected to steam curing, the quality of concrete is guaranteed, the concrete cured on the construction site cannot provide good conditions for steam curing and is influenced by weather, and the curing quality cannot be compared with that of the prefabrication factory.
However, the prefabricated concrete structure also has some disadvantages, such as low seismic performance and energy consumption performance of the shear wall, complex node connection form and difficult connection.
