Description

A kind of steel joint precast and assembled reinforced concrete frame structure

Technical field

The invention discloses a kind of steel joint precast and assembled reinforced concrete frame structure that is used for civil construction project, belong to the civil engineering work technical field of structures.

Background technology

The form of building structure has a lot, and wherein frame construction is a kind of widely used architecture structure form.Along with society to the deepening continuously of environmental protection theory, assembly structure can be considered to a kind of architecture structure form of low-carbon environment-friendly in the production that realizes in the factory having under the control because of its member.Prefabricated assembling framework structure has steel work, prefabricated assembling reinforcing bar frame construction and precast and assembled reinforced concrete frame structure at present.Steel work is from heavy and light, and ductility is good, but the cost height, fire line is poor.The precast and assembled reinforced concrete structural cost is low relatively, but its structural integrity is subjected to the restriction of beam column connected mode, and structural performance differs greatly.The performance of prefabricated assembling reinforcing bar frame construction then is a kind of the trading off between steel work and precast and assembled reinforced concrete frame structure.

Its technological difficulties of reinforced concrete frame structure for prefabricated assembling are how to carry out the connection of prefabricated units such as post beam, and satisfy the requirement of earthquake resistant structure.The method that solves the connection of reinforced concrete frame column girder connection at present both at home and abroad mainly contains cast-in-place node area node connection and the connection of prestress prepressing node etc.The connection of cast-in-place node area is to reserve pouring concrete position, back at the bean column node place, after finishing, each member on-site consolidation builds as placed concrete at pouring concrete position, back again, make between each parts and be linked to be integral body, it on structural performance more near the frame construction performance of integral cast-in-situ, thereby anti-seismic performance easily satisfies structural requirement, but, cast-in-place node area has the operation of part situ wet owing to needing formwork and concreting, and cast-in-place concrete frame joint needs curing time to use, cause the on-site construction processes complexity, duration lengthening, on-the-spot wet trade have also influenced the environment of construction to a certain extent.For solving the deficiency of cast-in-place node, take the reinforced concrete frame structure of prestress prepressing bean column node at present.It is the method for utilizing the post-tensioned prestressing muscle that the node of this frame construction connects, reinforced concrete prefabricated beam is pressed on the prefabricated post, rely on frictional force between the post beam or be aided with the power transmission that the shearing resistance of non-prestressing tendon comes the implementation framework node, post and the other method that then adopts being connected of intercolumniation such as joint bar injecting glue method etc.The moulding of this structure presstressed reinforcing steel that places one's entire reliance upon, also need carry out subsequent handlings such as presstressed reinforcing steel installation, stretch-draw and grouting again behind the component assembly, could finally finish node connects, thereby mounting process and fail at all to obtain to simplify, the dystopy connection of post beam makes also and loses independence between member that the member that damages after the earthquake is difficult for changing.
