Background technology
Steel building has the intensity height,, anti-seismic performance fast from heavy and light, speed of application reaches well the industrialization degree high.Steel structure member forms structural system by connected node, and the selection of joint form has direct impact for structural integrity, reliability, construction period and Accessory Members design and construction.
Steel structure node is mainly realized splicing and the connection of the members such as beam, post, support.Existing steel structure node is various informative, can be divided into rigid joint, hinged joint and structures with semi-rigid joints according to the node force-transfer characteristic.Connected mode has weld seam connection, bolt connection, rivet connection etc., and rivet connects now seldom use.
There are some shortcomings in existing steel structure node, for example:
1, weld seam connection construction technique is high, the work high above the ground difficulty large and produce the site operation that the problem such as electric spark is unfavorable for steel building.
2, weld seam connects the Fast Installation that is unfavorable for realizing steel building consuming time more.
3, general steel structure node needs protrusion to be connected member owing to there are the structures such as cover plate, otic placode, flanged plate, and design and construction have a negative impact to adjacent members.As: in order to realize the up and down splicing of two uniform section steel pipe columns, there are cover plate, otic placode, bolt etc. to protrude from the size all around of post, the layout of body of wall can be affected, perhaps need add thick wall body to cover post and post column joint structure, perhaps allow post and post post node protrude from outside the body of wall, affect attractive in appearance and space utilization.
The utility model content
The utility model provides the T-shaped bolt slotted hole splicing of a kind of square steel pipe inner sleeve node, solve the inconvenience of node connected mode on-site construction operations, complicated, the node insufficient rigidity of connecting elements design and construction of existing square steel pipe, and the technical problem that needs to change physical dimension after installing.
The technical scheme that its technical problem that solves the utility model adopts is:
The T-shaped bolt slotted hole splicing of this square steel pipe inner sleeve node comprises epimere square steel pipe and hypomere square steel pipe, and this node also comprises inner sleeve and the T-shaped bolt that is connected between epimere square steel pipe and the hypomere square steel pipe;
Described epimere square steel pipe lower end wall respectively has at least one slotted hole A, and hypomere square steel pipe upper end wall respectively has at least one slotted hole B;
Described inner sleeve is the rectangle column, the inner sleeve first half with the epimere square steel pipe on slotted hole A corresponding position have the top slotted hole, the inner sleeve Lower Half with the hypomere square steel pipe on slotted hole B corresponding position have the bottom slotted hole;
The bolt head of described T-shaped bolt is Long Circle, and the slotted hole on the shape of bolt head and square steel pipe and the inner sleeve is complementary, and the long length of side of bolt head is in the minor face of slotted hole;
The described inner sleeve first half inserts that the epimere square steel pipe is inner and by T-shaped bolt the two is fixed, and the bolt head of T-shaped bolt passes slotted hole A and top slotted hole, and with slotted hole in vertical state, locked with the screw rod of T-shaped bolt by the outer nut of epimere square steel pipe again;
Described inner sleeve Lower Half inserts that the hypomere square steel pipe is inner and by T-shaped bolt the two is fixed, and the bolt head of T-shaped bolt passes slotted hole B and bottom slotted hole, and with slotted hole in vertical state, locked with the screw rod of T-shaped bolt by the outer nut of hypomere square steel pipe again.
The long limit size of slotted hole is than the large 1~2mm in long limit of bolt head on described epimere square steel pipe, hypomere square steel pipe and the inner sleeve, and the minor face size is than the large 0.5~1.5mm of minor face of bolt head.
Bolt hole on described epimere square steel pipe and the hypomere square steel pipe wall is two rows, two row.
The beneficial effects of the utility model are as follows:
1, the utility model is offered the inner sleeve of slotted hole and the splicing that T-shaped bolt is realized square steel pipe by sidewall, and node rigidity is larger, easy and simple to handle.Member all can be by factory process, on-the-spot directly assembly unit, and speed of application is fast.The node area no-welding-seam can overcome that welding procedure length consuming time, complicated operation, quality are difficult to guarantee, exist the shortcoming such as fire safety evaluating hidden danger.
2, the utility model adopts specially designed T-shaped bolt, and T-shaped bolt is its bolt head one side size greater than the another side size with the difference of general bolt, and the slotted hole that bolt head can be filled in connected party's steel pipe sidewall is inner, only externally tightens.Therefore only have nut to protrude after construction is finished and be connected the member periphery, more traditional otic placode, flange connection have greatly reduced bulge size, make things convenient for the design and installation of adjacent members.Because slotted hole minor face size less than the long limit of bolt head, therefore can avoid bolt to extract and stressed.
3, the utility model node adopts slotted hole to carry out the connection of bolt, and slotted hole has been reserved the space for being connected the member slip.As using in building structure, can make structure under geological process, utilize the sliding friction power consumption of member between slotted hole, therefore increased steadiness and safety that node connects, have good anti-seismic performance.
Joint form of the present utility model is easy and simple to handle, speed of application is fast, installation accuracy is high, save the labour, has broad application prospects at the construction steel structure construction field.
