The method that plate is connected with post in the steel building
Technical field
Steel building design field of the present invention, the method that plate is connected with post in particularly a kind of steel building.
Background technology
Will consume soil, clay etc. in a large number in the traditional architecture, and soil resource is limited, people can only go to excavate field in blocks, thereby cause the very big destruction of land resources.So steel building is all being carried out in countries in the world now, steel work can not only economize the land resource, and steel work also has much other supremacy clauses, structure organization as steel is even, intensity is high, modulus of elasticity is high, plasticity and good toughness, the seismic load that is suitable for withstanding shocks, the density of steel and intensity smaller, steel work is compared with reinforced concrete structure and is wanted light by 30%~50%, and steel work is convenient to mechanization production, is the highest a kind of of industrialization degree in the engineering structures.But, can not deny that steel work also exists defective and hidden danger.1. the temperature tolerance of steel is relatively poor, and its many performances change with gradient of temperature, when temperature reaches between 430-540 ℃, the yield force of steel, anti-connects intensity and modulus of elasticity will sharply descend, and loses supporting capacity, and vertical slump forms " flat cake " effect.General sprayed fire proofing lacquer or the parcel fire proofing material of adopting.2. poor-performing is lost at the anti-mansion of common iron, and it is bigger especially to be in humidity, and in the environment of the medium that is corrosive, meeting corrosion has soon weakened bearing of component.The general rust prevention by applying liquid material lacquer that adopts.3. structural instability.Unstability is divided two big classes: whole unstability and local buckling.A large amount of accidents show that steel structure member is owing to the intensity height, and used cross section is relatively little, also just lose stable easily.Whole unstability great majority are caused by local buckling, when the pressurized position or be subjected to the slenderness ratio of turn of bilge position to surpass permissible value, can lose stable.So steel building is not very smooth China's implementation.At present, steel building adopts steel frame+support or steel frame+seismic structural wall, earthquake resistant wall system mostly, the connected mode of steel column, girder steel rigidly connects and articulated manner in the steel frame, the general employing in earthquake zone rigidly connects contact, adopt welding or bolt that steel column and girder steel are linked to be integral body, also have employing not only to weld but also bolt mixes ways of connecting, all these connected modes all are joint pin and beam, do not find the connected mode of steel column and stiffener.
Summary of the invention
The inventor holds the design concept of grasping strong column and weak beam in the architectural design, has designed a kind of post, plate building system, and cancellation beam or reduction beam action lump together beam with hardening.Around the plate is to be welded into frame by channel-section steel, the base plate that can pour a layer concrete formation superimposed sheet during construction in square frame earlier is connected with post again, last integral cast, or with the frame of post and plate connect good after, casting again, this post, plate building system have been improved force path, improve building and adapt to deformation ability, reduce geological process, but the method for attachment of post and plate is very crucial.
The present invention is directed to above-mentioned post, plated construction, the method that plate is connected with post in a kind of steel building is provided, adopt this method, make that the intensity and the stability of post, panel construction structure system are good, it is strong to adapt to deformation ability, and the anti-seismic performance, stability that make post, panel construction structure system are than ordinary steel structure height.
Technical scheme of the present invention is as follows:
The method that plate is connected with post in the steel building is characterized in that post is connected by angle steel formula junction plate with the intersection area of the steel work frame of plate, and the both sides that utilize angle steel formula junction plate are by bolt difference junction plate and post.
The intersection area of the steel work frame of described plate is the bight of plate.
Described bolt is a high-strength bolt.
Described plate angle upper fixed is connected with angle steel, and described angle steel is connected by bolt with one side of angle steel formula junction plate on one side.
Described post outer is fixedly connected with the support shear connector, and one jiao of described plate just in time is held on the supporting shear connector.
Described supporting shear connector is a square steel, and described square steel is welded on the post outer.
Described post is a H shaped steel, is fixedly connected with plate always between two straight flanges of this H shaped steel, makes that the steel column section is " day " font in post and the section that plate links to each other.
Technique effect of the present invention is as follows:
The present invention adds an angle steel formula junction plate at post, plate connecting place, and post is linked to each other by bolt with junction plate with junction plate, plate, thereby realizes that post, plate link to each other.The preferred high-strength bolt of bolt.The also available burnished bolt that satisfies requirement of strength of high-strength bolt replaces.The preferred angle steel of junction plate.It can also be other other form that can play firm interconnect function.Be to increase steadiness, at the last angle steel of top, angle welding of plate (being square frame), angle steel is connected by bolt with junction plate, and making like this can increase several high-strength bolts more and fixed between post, the plate, has improved the reliability of steel work contact connection.The post outer is fixedly connected with the supporting shear connector, can very easily plate be shelved on the supporting shear connector before with bolt, saves labor, and is convenient to operation, can also make building can bear bigger earthquake distortion, improves anti-seismic performance.Generally all use H shaped steel, square steel pipe etc. at the steel structure system center pillar, but H shaped steel has only two plate faces, so between its straight flange, be fixedly connected with plate always, make between stiffener and H steel column and can increase a junction plate, the steel column section is " day " font in the contact scope, has increased the steadiness of structure.
The method that plate is connected with post in the steel building of the present invention, by adopting junction plate, angle steel and supporting shear connector structure combining, it possesses following advantage: (1) junction plate firmly links together plate and post, Ban Jiao is provided with angle steel simultaneously, fix by bolt and junction plate, more increase the bonding strength between post, the plate, increased the stability of building.(2) be fixedly connected with the supporting shear connector on the post angle, can be used as the temporary support point when plate is installed, help fitting operation, after post, plated construction form, the supporting shear connector will be born most of shearing that plate transmits simultaneously.(3) this method of attachment between post, the plate can be at pillar one jiao, two jiaos to four jiaos of trigonometric sums, can be bight or frame at stiffener, only need to hand over the i iron form become " day " font formula and get final product in the junction.(4) method that is connected with post of plate of the present invention is directly transmitted load to post by plate, has reduced middle power transmission link, and is stressed clear and definite, good reliability.
