Description
Technical field
The utility model belongs to building structure connecting elements technical field, the joint pin in the concrete connected node district that must be a kind of girder steel and composite steel concrete column.
Background technology
Steel concrete, as two kinds of the most frequently used constructional materialss, has its advantage and economic benefits separately.In building structure, more and more fully playing the two feature and characteristic.Rigid steel reinforced concrete column is taking stiffness cross (or H type) steel frame as post core, steel frame and Combined concrete, the effect of common bearing load.This structure, there is the two-fold advantage of steel work and reinforced concrete structure, give full play to the characteristic of concrete (pressurized) and two kinds of different materials of steel (tension), compared with reinforced concrete structure, the bearing capacity that has improved post, has reduced column section, has reduced amount of concrete, alleviate dead load, reduced the load to ground.Compared with steel work, its saving steel, refractory ability is strong, strengthens the rigidity of structure and building, and damping performance improves, and anti-seismic performance is good, and has higher intensity.And speed of application is fast, easy to operate.
But will relate to the problem how reinforcing bar is communicated with and is connected in the time that girder steel or steel frame beam are connected with stiff steel reinforced column, traditional connected mode is perforate reinforcement on steel plate, and reinforcing bar passes from hole, by girder steel and stiff steel reinforced column is strap-on links together; Or on steel plate welded reinforcement junction plate or reinforcing steel bar connecting sleeve tube.
There is following problem in traditional node:
(1) when longitudinal reinforcement beam-column is closeer, the perforate of post on the steel corbel edge of a wing also can be closeer, larger to the weakening of the bracket edge of a wing, and Kong Taimi, can make stiffening plate reinforcement for openings not meet structure requirement;
(2) the stirrup hole of opening on steel corbel web, if make bracket web plate section loss late exceed designing requirement, web also needs to carry out reinforcement or employing is welded to connect, and also has the problem such as perforation difficulty and the requirement of stiffening plate structure simultaneously;
(3) if run into the vertical muscle of post for the reinforcing bar junction plate of the vertical flaccidity of tendon and muscle of welded grider, need open and clear processing, in the situation that vertical muscle is intensive, also there will be situation about cannot arrange.
Summary of the invention
The present utility model object is to overcome prior art deficiency, provide a kind of power transmission reasonable, the joint pin of the simple a kind of girder steel of node processing and composite steel concrete column, comprise one section with the casing of the same shape of building structure cylinder, and the concrete of annotating in casing forms one section of node cylinder, the post heart of described node cylinder adopts building structure cylinder reinforcing bar used, a side of described node cylinder is connected with bracket frange plate and is positioned on bracket frange plate, under reinforcing bar junction plate, in described node cylinder, stiffener is established in corresponding bracket frange plate and/or reinforcing bar junction plate position.Described stiffener is divided into lateral stiffening plate and longitudinal stiffener, described lateral stiffening plate has been filled the vacant plane space except the post heart in described casing, only stay concrete casting grout, described longitudinal stiffener is located at one side and the lateral stiffening plate determined right angle of casing for affixed bracket frange plate or reinforcing bar junction plate.
The girder steel that the utility model is recorded and the joint pin of composite steel concrete column, make the processing construction of node fairly simple, avoid on steel plate intensive perforate, later stage to need the work of reinforcement, the load intensity that guarantee tie point is set of stiffener, can ensure the reasonable power transmission of structure at Nodes, and meet the principle of strong node.

In figure, bracket frange plate 1, reinforcing bar junction plate 2, casing 3, longitudinal stiffener 4, the post heart 5, lateral stiffening plate 6, concrete casting grout 7, beam is indulged muscle 8, and post is indulged muscle 9, and post is indulged muscle junction plate 10, building structure post 11.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is illustrated, the joint pin of a kind of girder steel and composite steel concrete column, comprise one section with the casing 3 of building structure cylinder 11 same shapes, and form one section of node cylinder at the interior filling concrete of casing 3, the post heart 5 of described node cylinder adopts building structure cylinder 11 reinforcing bar used, a side of described node cylinder is connected with bracket frange plate 1 and is positioned at the upper and lower reinforcing bar junction plate 2 of bracket frange plate 1, and in described node cylinder, stiffener is established in corresponding bracket frange plate 1 and/or reinforcing bar junction plate 2 positions.Described stiffener is divided into lateral stiffening plate 6 and longitudinal stiffener 4, described lateral stiffening plate 6 has been filled the vacant plane space except the post heart 5 in described casing 3, only stay concrete casting grout 7, described longitudinal stiffener 4 is located at one side and the lateral stiffening plate 6 determined right angle of casing 3 for affixed bracket frange plate 1 or reinforcing bar junction plate 2.
The connected mode of this node and building structure post 11 can be top edge and the lower limb that the vertical muscle 9 of post is directly welded on casing 3, also can be at the top edge of the casing of joint pin 3 and the vertical muscle junction plate 10 of the affixed post of lower limb, make the vertical muscle 9 of post affixed with the vertical muscle junction plate 10 of post, can avoid like this casing 3 section bars destroyed.
The main thought of this node is exactly to replace the vertical muscle of post and column tie-bar by the box section post of node area changeover portion, simplifies open and clear etc. the object of reinforced steel bar perforation, reinforcement, the reinforcing bar junction plate of node area to reach; Joint pin has all carried out grade with the vertical muscle of post up and down and has effectively been connected by force, and the intensity of joint pin can be ensured by calculating; In post, reinforcing bar runs through whole node area, ensures continuously; Casing 3 cross sections are closed cross-section, and concrete is had to strong hoop effect, can replace the effect of former column tie-bar completely; Girder steel is connected with post by bracket, the vertical muscle 8 of beam can be connected with node cylinder by reinforcing bar junction plate 2, and the position of corresponding bracket frange plate 1 and/or the position of reinforcing bar junction plate 2 arrange corresponding stiffener in node cylinder, ensure rationally and effectively transmitting of power.
In addition, the vertical muscle 8 of beam is not limited to tabular junction plate shown in figure with the connected mode of node cylinder, and described reinforcing bar junction plate 2 also can be made the form of branch sleeve.
In node cylinder, stiffener is established in corresponding bracket frange plate 1, reinforcing bar junction plate 2 positions, if stiffener spacing is too near, also can cancel one stiffener, ensures the transmission of power by longitudinal stiffener is set.
The girder steel that the utility model is recorded and the connected node of composite steel concrete column are all having good performance aspect the transmission of joint form or power; Avoided on steel plate intensive perforate, later stage to need the work of reinforcement, ensured the reasonable power transmission of structure at Nodes, node is simplified significantly simultaneously, and difficulty of construction is also reduced.
