Description
Technical field
The utility model belongs to building structure technology field more particularly to a kind of prefabricated column connected node of inflection point.
Background technique
For assembled architecture when constructing assembly, prefabricated post connection type mainly includes the following two kinds mode: (1) grout sleeve
Connection type: it in the Ribbed Bar insertion metal sleeve for needing to connect " docking ", is covering similar injection high-strength morning by force and is having micro-
The grouting material of expansion, grouting material form biggish normal stress between sleeve wall and reinforcing bar, in the coarse table of Ribbed Bar
Face generates huge frictional force, thus transmits axial force.The requirement that this connection type obtains employment to worker is very high, and each of column
Vertical muscle requires to use sleeve connection, therefore the contraposition of reinforcing bar is even more important in construction, but is not easily achieved very much this in being
Point.
(2) it starches anchor on-link mode (OLM): the Ribbed Bar for needing to connect being inserted into the reserving hole channel of prefabricated components, reserving hole channel
Inner wall is spiral.After reinforcing bar is inserted into duct, high-strength morning is injected in duct by force and has the grouting material of microdilatancy, is fixed with anchor slotting
The reinforcing bar entered.It is the steel bar stress being embedded in component beside duct, the reinforcing bar being inserted into duct " overlaps " therewith.With set
Cylinder connection is similar, and each reinforcing bar requires to connect, and construction reinforced bar contraposition needs a large amount of time, and therefore, this is not optimal
Elegant connection type.
The grout sleeve connection type or slurry anchor chain used at this stage connects connection type, the valence of sleeve and dedicated grouting material
For lattice due to production technology, price is very high.Assembled cost is greatly improved relative to traditional architecture at this stage, assembled at
First tongue is made us in this increase of cost in prefabricated post.
When construction, prefabricated post at this stage is connect by every reinforcing bar with sleeve or slurry anchor node, and process is extremely complex,
Once there is the smaller error of construction, entire node security will lead to, globality is had a greatly reduced quality, or even influence the safety of structure entirety
Property.And in the construction process, it is necessary to after the hardenability that grouting material reaches certain, just can be carried out subsequent construction and make
Industry largely affects construction period.
In beam column node core area, the stress of complication makes the whole sexual deviation of structure for prefabricated node selection at this stage, this
It is runed counter to structure design and Aseismic Design.
In conclusion needing to develop, a kind of stress is simple and reliable, structure whole highly-safe, recurvation that construction efficiency is high
The prefabricated column connected node of point.
Utility model content

It states in prefabricated post and lower prefabricated post, first cuff and the second cuff are connected by connecting plate, and the upper prefabricated post is under
Annular groove is formed after prefabricated post splicing, the connecting plate is arranged in the annular groove.
In framework design, at the floor moment of flexure inflection point of column, the utility model stress is relative to joint core
Area's stress is simple, and prefabricated post height is that upper strata post inflection point is equal with joint cores to shearing between lower floor's post inflection point, curved
Square is zero, and torque can almost be ignored, and the safety of structure entirety and integrally-built anti-side rigidity increase.In addition, this is practical
Novel no grout sleeve or slurry anchor connection, cost substantially reduce, and lower prop is without cast-in-place node on construction site, and construction period is significantly
Shorten;The all welding for steel structure in construction site simplify construction procedure.And this patent is without overhead welding, assembled inflection point prefabricated post
Both it ensure that construction quality in turn ensured that connecting node is safe and reliable;Wet construction is almost nil, and column is connected without the few cost of template
And construction period is reduced, it reduces artificial;Assembled inflection point prefabricated post since beam column node core area is prefabricated in the factory, column
Ductility and anti-side rigidity are enhanced;In processing and fabricating, exposed steel bar is seldom for prefabricated components factory, and mold is simple, and processing is more
Add conveniently;Phase component is readily disassembled assembled inflection point prefabricated post after maintenance, can be individually replaced for some column.
Further technical solution is, first cuff and the second cuff are embedded in the upper prefabricated post and lower pre- respectively
In column processed, framework of steel reinforcement, first cuff and the second cuff and the reinforcing bar are equipped in the upper prefabricated post and lower prefabricated post
Skeleton is fixedly connected.So set, node globality is more preferable, be conducive to the transmitting of power.
Further technical solution is that the connecting plate and first cuff, the welding of the second cuff are integral.In this way,
Construction is simple, connection is reliable, wet-less operation, can effectively improve construction efficiency, saves the duration.
Further technical solution is that the Mosaic face of the upper prefabricated post and lower prefabricated post is equipped with leveling mortar.Levelling sand
Slurry is conducive to adjust the flatness of prefabricated component, while making the cohesive force of prefabricated post joint face bigger, can also assemble in prefabricated post
The process of dropping place plays certain buffer function, direct collision when avoiding prefabricated post dropping place and damaged member.
Further technical solution is that the Mosaic face of the upper prefabricated post and lower prefabricated post is rough surface.When assembly, it can lead to
The tools such as steel brush or sand paper are crossed the contact surface polishing of plush copper is coarse, so set, leveling mortar can be such that the connection of plush copper imitates
Fruit is more preferable.
Further technical solution is to be provided with reinforcement steel plate at the top of the lower prefabricated post.It is arranged such, it is possible to increase lower pre-
The rigidity of column top processed is conducive to it and bears the bigger pressure from other prefabricated components.
Further technical solution is that the connecting plate, cuff make antirust fireproof processing.Relative to assembled steel at this stage
Structure, fire protecting performance greatly promote, and antirust treatment area greatly reduces.
