Description

A kind of prefabricated assembled bean column node box
Technical field
The present invention relates to a kind of concrete column-steel beam joint, more particularly to a kind of prefabricated assembled concrete post-girder steel Node box.
Background technology
With the continuous development of high building structure form, there is increasing new Mixed Architecture, reinforcing bar Concrete column-steel beam combined structure system (reinforced concrete column-steel beam, abbreviation RCS combination knots Structure system) have the double dominant of steel construction and concrete structure concurrently, it is referred to as the structure type of " low-cost high-efficiency ", it and steel Structure is compared to having a saving steel, the characteristics of increase building rigidity, meanwhile, there is higher stability and durability;With mixing Xtah Crude Clay structure, which is compared, has the characteristics of reducing sectional dimension of members, increase structural span, increase structure ductility, therefore has obtained crowd More scholars widely pay close attention to.For ensure reinforced column and girder steel between the two can reliable power transmission, rational structure type It is most important.
Although having carried out many correlative studys in recent years both at home and abroad, overwhelming majority research is all to be centered around cast-in-place node Under form, the research for prefabricated assembling type reinforced concrete post-steel beam joint is very few, and reinforced column-girder steel is mixed Close structure to be applied among prefabricated assembled, develop assembled Mixed Architecture, this is applied for changing the extensive building in China Work industry, architectural industrialization development trend is complied with, undoubtedly with important economy and social effect.
Patent publication No. is " A of CN 103255841 ", a kind of entitled " assembly concrete post-girder steel extended end plate Type node ", a kind of node is disclosed, it includes precast concrete column, steel structure set, girder steel, end plate and high-strength bolt, the girder steel Including pre-buried girder steel and interlude girder steel, the steel structure set includes a pair of matrix pattern lattice corals being made up of some blocks of steel plates, described A pair of matrix pattern lattice corals are arranged and welded together by vertical four angle steel up and down, along angle steel outside between each two angle steel Weld horizontal band steel, a pair of matrix pattern lattice corals are respectively welded at the upper lower flange of pre-buried beam, girder steel and steel structure set is welded into one Individual entirety, the upper end of precast concrete column is placed on, the joint core region concrete between steel structure set and girder steel mixes with prefabricated The concrete one-time-concreting of solidifying earth pillar is completed, and pre-buried girder steel and interlude the girder steel both sides are respectively welded end plate and pass through height Strength bolt connection is integral.In the device, the joint cores between steel structure set and girder steel can be not provided with stirrup, reduce and apply Work process, but core space concrete need to first be poured completion together with precast concrete column in factory, then transport to scene Assembled so that transport and assembly difficulty are larger.
Therefore, it is necessary to develop a kind of prefabricated node unit, asked with solving the connection of reinforced column-steel beam joint Topic.
The content of the invention
For deficiencies of the prior art, the present invention provides a kind of prefabricated assembled bean column node box, the section Point box and concrete prefabricated column, prefabricated girder steel etc. can be independently prefabricated in precast plant, installed after transporting to scene, not only Convenient transportation, and assembling is simple, adapts to a variety of occasions.
To reach above-mentioned purpose, the present invention provides following technical scheme:

As a preference of the present invention, the center-side is connected integral with the external part in " one " word, this structure is fitted For post and wall in conplane occasion.
As a preference of the present invention, the center-side is connected integral with the external part in " ten " word, this structure is fitted The occasion being connected for two face walls to intersect vertically with post.
As a preference of the present invention, the cassette body is steel plate, square, rectangle or circular cylindrical shape are enclosed.
As a preference of the present invention, the cassette body be plank sheathing or plywood form or plastic formwork or Person's glass steel formwork or aluminum alloy mould plate, enclose square, rectangle or circular cylindrical shape, and close to the plank sheathing or Stirrup, the short girder steel are provided with the inside of plywood form or plastic formwork or glass steel formwork or aluminum alloy mould plate Center end web be provided with stirrup hole.
As a preference of the present invention, the center-side edge of a wing of the short girder steel is provided with vertical muscle hole, convenient vertically vertical muscle passes through.
As a preference of the present invention, the center-side edge of a wing 45% -85% of the short girder steel is cut off, and for convenience of vertical Vertical muscle passes through, and the position that excision position should be made to be passed through with vertical vertical muscle is corresponding.
As a preference of the present invention, the center-side edge of a wing of the short girder steel is cut off completely, convenient vertically vertical muscle passes through.
The connected mode of the present invention:
First welding can be used in the prefabricated independent concrete column of precast plant, girder steel, node box, each part of node box Or bolted mode is attached, and is transported to after scene, bottom concrete column, node box are sequentially placed from the bottom to top Son, top concrete column, and make them be located on same center line, then stretches prefabricated girder steel and short girder steel in node box Go out end to be attached, can be connected by screw bolts, either weld or the modes such as part bolted on part welds are attached, Slurries finally are injected from the injected hole of cassette body bottom, concrete column, girder steel is connected with node box integral.
The beneficial effects of the present invention are:
1st, node box is completely prefabricated, and installation rate is fast, quality is good, adapts to a variety of occasions.
2nd, cassette body using steel plate as template when, only need to dock with the upper and lower post of precast concrete during assembled in situ After can pour core space concrete, reduce working procedure and construction cost.
3rd, when cassette body uses steel plate as template, it is not necessary to stirrup is set again, the splice of node area can be reduced and connected Connect, simplify node area construction.
4th, cassette body can produce effect of restraint to core space concrete, improve its stress performance, effectively improve its shearing resistance Intensity and ductility.
