Dry and wet mixed connection joint and construction method thereof

Abstract

The invention provides a dry and wet mixed connection joint and a construction method thereof. The dry and wet mixed connection joint comprises a connecting piece horizontally arranged between a firstconcrete plate and a second concrete plate. Guiding grooves are formed in the matching faces of the first concrete plate and the second concrete plate correspondingly. A spring is arranged at the bottom of the guiding groove of the first concrete plate. A first pin hole vertically penetrates through the side face of the guiding groove of the first concrete plate. A connecting pin penetrates through the first pin hole and the connecting piece to compress the spring at the bottom of the guiding groove of the first concrete plate. A second pin hole vertically penetrates through the side face ofthe guiding groove of the second concrete plate. The connecting pin is pulled out, and the connecting piece is popped into the guiding groove of the second concrete plate along the guiding groove of the first concrete plate under the action of the spring. The length of the connecting piece is greater than that of the guiding groove in the second concrete plate. The connecting pin is inserted intothe second pin hole and the connecting piece, and concrete is cast in place in the first pin hole and the guiding groove of the first concrete plate. The dry and wet mixed connection joint simultaneously has the advantages of dry connection and wet connection.

Description

technical field [0001] The invention belongs to the technical field of building structure connection, and more specifically relates to a dry-wet hybrid connection node and a construction method thereof. Background technique [0002] At present, with the rapid development of building industrialization, prefabricated reinforced concrete structures are one of the important directions for the development of building structures. They are assembled by connecting and assembling prefabricated concrete components. English abbreviation, which means prefabricated concrete) structure is conducive to green construction, and can better meet the requirements of green construction, such as land saving, energy saving, material saving, water saving and environmental protection, and reduce the negative impact on the environment, including reducing noise, preventing Dust, reduce environmental pollution, clean transportation, reduce site interference, save water, electricity, materials and other...

AI Technical Summary

Problems solved by technology

[0009] The purpose of the present invention is to provide a dry-wet hybrid connection node and its construction method to solve the wet connection existing in the prior art, which is cumbersome in construction, complex in structure, indirect in force transmission, high in construction cost, difficult to satisfy heavy load, anti-corrosion Strong cracks and integrity, poor ductility of connecting nodes, and technical problems that energy cannot be dissipated well during earthquakes, and the dry connection structure has a large gap with the cast-in-place assembly frame structure due to loose overall performance, making it difficult to prevent earthquakes Technical problems of failure under load
