Problems solved by technology

However, the main factor restricting the development of prefabricated concrete structures is: the lack of safe, reliable and fast installation of prefabricated concrete components on-site connection method
At present, the most widely used node connection method is to use straight thread sleeve grouting connection. This method is a wet connection method. It is necessary to support the formwork in the frame node area on the construction site, and the reserved steel bars of prefabricated beams and prefabricated columns are used. Threaded sleeve connection, and then pouring joint concrete, the curing time is longer, compared with the traditional cast-in-place concrete structure, this production method does not have the advantage of shortening the construction time of the main project

Embodiment Construction

[0034] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] In the existing technology, most of the concrete frame connection nodes are cast-in-situ or prefabricated wet connections. The cumbersome binding of steel bars affects the construction progress, the quality of on-site construction cannot be guaranteed, and the wet construction will have negative impacts on the surrounding environment and residents. The invention provides a prefabricated beam-column connection device, which is a new type of prefabricated frame dry connection node, without the need for concrete pouring and steel bar binding at the construction site, which is convenient for construction, quick in operation, shortens the construction period, and is benef...

Abstract

The invention provides a precast beam and column connecting device and a manufacturing method thereof, and relates to the technical field of civil engineering. The precast beam and column connecting device comprises a precast beam and column connecting joint, column-end pre-embedded steel components and beam-end pre-embedded steel components; the precast beam and column connecting joint comprises a first steel rib connecting piece and a second steel rib connecting piece; the first steel rib connecting piece and the second steel rib connecting piece fit crosswise and are integrally formed by casting; the column-end pre-embedded steel components are connected with the end face of the first steel rib connecting piece; the beam-end pre-embedded steel components are connected with the end face of the second steel rib connecting piece. Through the device, beam ends and column ends can be connected together only by adopting a lifting and splicing process in a construction site, so that construction progress is greatly increased; the precast beam and column connecting device is convenient in construction, rapid to operate, capable of shortening a construction period, in favor of environmental protection and noise control and convenient to transport, assemble and disassemble, and can be produced on a large scale in a short time.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a prefabricated beam-column connecting device and a manufacturing method thereof. Background technique [0002] At present, most of the structural projects in our country adopt the cast-in-place concrete frame structure, which is characterized by good integrity and strong seismic performance. However, the cast-in-place concrete structure requires steps such as setting up formwork, binding steel bars, pouring concrete, and curing at the construction site. Its construction process is complicated, the construction period is long, there are many wet operations on site, and problems such as environmental pollution and noise nuisance have attracted more and more attention from the whole society. [0003] Based on the above factors, in response to the national building structure industrialization and industrialization development policy, prefabricated concrete structures came...
