Abstract
The utility model relates to a steel tube connecting technology and aims to provide a built-in rigid connecting joint for connecting steel tubes. The built-in rigid connecting joint comprises two sections of steel tube main bodies and connectors which are used for connecting the two sections of steel tube main bodies, wherein the quantity of the connectors is two; one part of each of the connectors is inserted and fixed in the steel tube main bodies; the two connectors are same in section shape; and the parts of the connectors exposed outside the steel tube main bodies are arranged oppositely and are fixedly connected through a clamping plate. The built-in rigid connecting joint can be conveniently produced in batches by a factory; the adopted bolt connection is beneficial to on-site quick and safe mounting; the quality of the connecting joint is ensured; and the connecting joint is built-in, thereby smooth transition of butt joint points of the steel tubes and beautiful appearance are realized.
Description
Technical field
The utility model relates to the steel pipe interconnection technique, and particularly a kind of built-in rigid joint has been realized adopting the bolt assembly unit to be connected to form rigid joint in steel duct.
Background technique
At present, the rigid joint of steel pipe is generally the lined steel pipe field welding or adopts flange to connect.
The former perhaps needs the steel pipe of installation at high altitude comparatively unfavorable for caliber is big; The one, caliber needs the overhead welding of big section than the big steel pipe bottom; Weldquality is difficult to obtain assurance, and the 2nd, the high-altitude welding job has potential danger to operator, and the high-altitude weldquality is difficult for guaranteeing equally.
It is at steel tube end part connecting plate to be set that flange connects, and bolt is connected in the steel pipe outside, forms a tangible flange plate in appearance, visually not quite attractive in appearance, and the higher building of appearance requirement is difficult to adopt.
Is connected the narrow limitation that is suitable for flange for overcoming lined steel pipe butt joint, a kind of technology that seamlessly transits that can avoid weldquality to be difficult for the shortcoming of assurance, can realize the steel pipe outward appearance again particularly necessity that seems is provided.
The model utility content
The technical problem that the utility model will solve is, overcomes deficiency of the prior art, and a kind of built-in rigid joint is provided, and this node adopts bolt to connect, and connected node is built in steel duct.
The utility model solves the technological scheme that its technical problem adopted: on steel pipe, slotting in advance is welded on steel duct with link; And on link in advance towards good bolt connecting hole; Through clamping plate and high-strength bolt two sections steel pipes are rigidly connected, connect at definite bolt and accomplish, after quality meets the related specifications requirement; At link outerwrap steel pipe, make the node that is rigidly connected place steel duct.
Specifically be expressed as: be used for the built-in rigid joint that steel pipe connects, comprise two sections steel pipe bodies, and the link that is used to connect two sections steel pipe bodies; Said link has two, and all some stretches into and be fixed in the inside of steel pipe body to each link; Two links have identical sectional shape, and it is exposed to the part positioned opposite beyond the steel pipe body and achieves a fixed connection with clamping plate.
As a kind of improvement, said two links are exposed to the part beyond the steel pipe body, and the parcel steel pipe is established in its outside.
As a kind of improvement, the sectional shape of said steel pipe body is any one in circle, ellipse or the rectangle; Said parcel steel pipe has and the on all four sectional shape of steel pipe body.
As a kind of improvement, the means of fixation of said each link and steel pipe body interior is to be welded to connect.
As a kind of improvement, said two links achieve a fixed connection with clamping plate: be on link and clamping plate, to establish corresponding through hole, and achieved a fixed connection by bolt.
As a kind of improvement, the sectional shape of said link is yi word pattern, man type, cross or Mi Zixing.
The beneficial effect of the utility model is: built-in rigid joint is convenient to factory's batch process, adopts the bolt connection to be beneficial to the scene and fast and safely installs, and guarantees the connected node quality; Node is built-in realized steel pipe butt joint node seamlessly transit beautiful shape.

Fig. 1 is the structural representation of built-in rigid joint;
Fig. 2 is the sectional view of A-A position among Fig. 1;
Fig. 3 is the sectional view of B-B position among Fig. 1;
Fig. 4 is that the utility model is with the scheme of installation of cylindrical steel tube as built-in rigid joint;
Reference character is among the figure: 1 steel pipe body, 2 links, 3 clamping plate, 4 high-strength bolts, 5 parcel steel pipes.
Embodiment
Pass through specific embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.
Embodiment: in Fig. 1-3, steel pipe body (1), link (2) are welded to connect in advance, are rigidly connected through clamping plate (3), high-strength bolt (4), and parcel steel pipe (5) covers link (2) makes node built-in.Usually the welding of steel pipe body (1) and link (2) can be carried out in factory in advance, and parcel steel pipe (5) can be accomplished and unified after the assay was approved the installation at all clamping plate (3), high-strength bolt (4).
According to the practice of construction needs, the sectional shape of steel pipe body (1) can be circle, ellipse or rectangle.The sectional shape of link (2) can be yi word pattern, man type, cross or Mi Zixing.
Above-described embodiment is a kind of preferred version of the utility model, is not the utility model is done any pro forma restriction, under the prerequisite that does not exceed the technological scheme that claim puts down in writing, also has other variant and remodeling.
Claims (6)
1. be used for the built-in rigid joint that steel pipe connects, comprise two sections steel pipe bodies, and the link that is used to connect two sections steel pipe bodies; It is characterized in that said link has two, all some stretches into and is fixed in the inside of steel pipe body to each link; Two links have identical sectional shape, and it is exposed to the part positioned opposite beyond the steel pipe body and achieves a fixed connection with clamping plate.
