Abstract
The utility model relates to a steel-pipe construction wedge-type connecting piece which belongs to the technical field of engineering building and construction. The utility model is designed for the purpose of providing a product which has the advantages of convenient assembly and disassembly, simple structure and high safety, and the utility model is composed of a pipe sleeve (attached figure-1), a wedge (attached figure-2) and a pin (attached figure-3). The utility model is characterized in that the pipe sleeve formed by an opening circular pipe which can be externally sheathed on a steel pipe on a plane with a same center and a supporting hook which is intersected with the opening side of the circular pipe into integration and can support another steel pipe vertical to the sheathing steel pipe forms a ring shape on the intersected point, and the wedge which is positioned on the point and is parallel with the central line of the opening circular pipe can tightly wedge two pipes which need to be connected. The connecting piece can achieve optional connecting modes among steel pipes during construction, and the special structure of the wedge with an I-shaped cross section enables each part not to be separated and to enable the connecting piece to be positioned for different requirements.
Description
The utility model is a kind of steel tubular structure connector, belongs to the engineering construction construction field, and its architectural feature is that wedge-type locking connects.
Be fastening with the Luo bolt with the steel tubular structure connector now, weak point is operation inconvenience and complex structure.
The purpose of design of wedge-type connector is to be to avoid weak point of the prior art, and a kind of easy accessibility, simple in structure and safe and reliable product are provided.
The purpose of this utility model reaches by following measure: the wedge-type connector by the wedge of the pipe box that connects steel pipe, fastening steel pipe with prevent that the pin that wedge separates with pipe box from constituting.Pipe box by same symmetrical centre plane, can outside be enclosed within the open-end tube on the steel pipe and intersect and be one with this tube opening side, can hold the hook of another steel pipe vertical with packing into steel pipe forms, the open-end tube of intersection forms closed-loop, and this place's inner edge and open-end tube center to center distance are greater than the outer radius of being inserted in the steel pipe in the open-end tube, and arrive open-end tube center to center distance less than steel pipe walls in the hook, make this place's inner edge outer tangent plane that steel pipe is drawn in hook become certain angle of cut with the open-end tube center line, this tangent plane is exactly the locking inclined-plane of wedge, and assembly key is located in this.Another locking face of wedge is the cambered surface parallel with the open-end tube center line, and the outer radius of the steel pipe in its arc radius and the open-end tube is isometric.Wedge its cambered surface when fastening is the parallel contact of cambered surface with steel pipe in being inserted in open-end tube; The vertical contact contacts with pipe box again inclined surface with the steel pipe in the hook is tangent.The cross section of wedge is except that big end is rectangle, and other place all is I-shaped.There are two projectioies with the central plane symmetry in wedge road in the pipe box, and when wedge was imported in the wedge road of pipe box by small end, its two side channel was embraced two protuberances in the wedge road in pipe box, loads onto pin in the aperture between small end two side channels again, and wedge is not separated with pipe box.
It is fastening for the wedge-type connector can be located on single steel pipe, the utility model reaches by following measure: each intermediate, inclined to wedge of the big end section ramp thickness of the wedge of the cambered surface thickness of the small end section of the wedge of the connector that contacts with steel pipe in the open-end tube and the connector that contacts with steel pipe in the hook, the two is reverse taper.Connector is located on a steel pipe earlier; When connector is located on the steel pipe in hook separately, the pine wedge is (oppositely tight wedge) or wedge tightly to utmost point place, just can make the both wings separately of clad can that two sections of wedge have a tapering in pipe box wedge road two protuberances and steel pipe between connector is located during by wedging on steel pipe.
Half place at pipe box is provided with peephole, so that butt joint connects.
In steel tubular structure, the utility model can be made cross to steel pipe and connect, docks and tilt to be connected, thereby only uses a kind of connector; The fastening convenience of wedge-type, speed of application is fast; Kind is single, and simple in structure, has created condition for reducing cost; This structure is also safer simultaneously.
Accompanying drawing is wedge-type connector (cross connection) scheme of installation, the 1st, and pipe box, the 2nd, wedge, the 3rd, pin, thin two-dot chain line is a steel pipe.
When doing the cross connection, generally overlap connector earlier on stand-by steel pipe with number as required; Behind the standpipe, will with connector be placed on desired location, loose wedge is (promptly the direction of motion of wedge is opposite when being fastenedly connected) to utmost point place location; Put into horizontal steel tube in the hook, hold connector on the other hand, another hand-tight wedge gets final product.
The butt joint steel pipe is that connection is fastening in the open-end tube of connector.Do vertical or during the butt joint of inclination steel pipe, generally the big wedge end of connector be enclosed within earlier and wait to connect the steel pipe lower end, with the wedge pine to location, utmost point place; Standpipe, and connector is enclosed within down steel pipe upper end; Normotopia, tight wedge can be fastenedly connected two pipes.Horizontal tube butt joint also connect class this.
When work supportted, draws steel pipe to connect, its inclination steel pipe and horizontal steel tube intersected, and connect with cross and realize.
The wedge-type connector also can be done being located by connecting of template etc.
The wedge-type connector is generally with malleable cast iron processing, the also available die forging manufacturing of chock.
Claims (2)
1, a kind of steel tubular structure wedge-type connector, constitute by pipe box, wedge and pin three parts, feature of the present utility model is: pipe box is formed by intersecting for the hook of one at the open-end tube on same symmetrical centre plane with this tube opening side, the intersection open-end tube forms closed-loop, and this place's inner edge and open-end tube center to center distance are greater than the outer radius of being inserted in the steel pipe in the open-end tube, and arrive open-end tube center to center distance less than steel pipe walls in the hook, making this place's inner edge outer tangent plane that steel pipe is drawn in hook become certain angle of cut with the open-end tube center line, serves as the locking inclined-plane with this tangent plane; With parallel with the open-end tube center line, and the isometric cambered surface of the outer radius of the steel pipe in arc radius and the open-end tube is the wedge of another locking face, can be fastenedly connected as wedge-type steel pipe, and can make connector do various location.
2, connector according to claim 1, it is characterized in that: wedge is the I-shaped cross-section, in its two clad can, small end section cambered surface thickness and big end section ramp thickness all have the tapering in the middle of the oblique wedge, make connector when being connected with single steel pipe, the both wings of two sections clad cans that its wedge has a tapering in pipe box wedge road two protuberances and steel pipe between during by wedging, and connector is located on steel pipe.
