Description
Technical Field
The invention belongs to the technical field of structural engineering, and particularly relates to a connecting node for an interlayer rubber pad vertically arranged on an assembled concrete shear wall structure and a construction method thereof.
Background
Along with the rapid development of the economy in China, the living standard of people is continuously improved, and the requirements on houses are increasingly improved. Meanwhile, the cast-in-situ construction mode of the house is not suitable for the sustainable development concept of China. At present, the problems of high energy consumption, high pollution, high investment and the like in residential construction are urgently needed to be solved in China, so that the urban and rural construction department of the development and reform commission house in China issues a green building action scheme, and the prefabricated construction systems such as prefabricated concrete structures, steel structures and the like which are suitable for industrial production are explicitly promoted, the prefabrication and assembly technology of development and construction engineering is accelerated, and the integration level of the building industrialization technology is improved.
The prefabricated concrete structure has the following advantages:
(1) And (5) green construction. The assembled concrete structure construction can better meet the requirements of land saving, energy saving, material saving, water saving, environmental protection and the like of green construction, reduces negative effects on the environment, comprises noise reduction, dust emission prevention, environmental pollution reduction, clean transportation, site interference reduction, water saving, electricity, material and other resources and energy sources, and follows the principle of sustainable development.
(2) The construction period is short. Because a large number of assembled concrete components are produced and maintained in factories, the work performed on the construction site is to hoist, assemble and reinforce the nodes of the prefabricated components in the prefabrication factory, so that not only is a scaffold and support not required to be installed, but also the influence of seasonal factors on the construction period is reduced, the work such as decoration, hydropower construction and the like is performed after the main structure is formed, the workload is far smaller than that of the cast-in-place construction, and even the working procedures of masonry and plastering are omitted, thereby greatly shortening the whole construction period.
(3) The component quality is good. The concrete in the prefabrication factory does not need pumping, the water in the concrete is less, and the strength grade of the concrete is higher than that of the in-situ casting. After the components are poured in the prefabrication factory, the components are subjected to steam curing, so that the quality of concrete is guaranteed, the concrete cannot be cured on the construction site, good conditions of steam curing cannot be provided, the components are affected by weather, and the curing quality cannot be compared with that of the prefabrication factory.
However, the prefabricated concrete structure has some defects, such as low earthquake resistance and energy consumption of the shear wall, complex node connection form and difficult connection. The existing main connection node forms need to bind reinforcing steel bars and cast concrete on site, and require scaffolds, templates and the like, so that hidden danger is brought to the quality of the node, the construction technical requirement is high, and the use of precast concrete members is limited to a certain extent.
