Abstract
The utility model discloses an anchor bolt for structural member connection, which comprises a taper nut, a sleeve and a screw, wherein an annular radial boss provided with anti-rotating structure is arranged on the rear end of the sleeve, at least a strip opening which is extended along axial direction to the central part is arranged on the front end of the sleeve; the screw is inserted from the rear end of the sleeve, the rear end is abutted against the rear end surface of the sleeve, the front thread end is in threaded connection with the taper nut on the front end of the sleeve; the small-diameter end of the taper nut is inserted into the sleeve, and moves toward the rear end of the screw along a screw rod, so the front sleeve body of the sleeve is gradually extended radially, and the extended front sleeve body of the sleeve is coordinated with the annular radial boss, so as to realize clamping fixation on a installed structure. The utility model solves the problem of inconvenient connection existing on the elongated, closed position of the structural member, and provides a connection device with simple structure and convenient use for engineering construction.
Description
Technical field
The utility model relates to a kind of structural member and connects crab-bolt.
Background technique
In industries such as construction engineering, manufacturing technologys, often a member need be installed on another member, but normal exist structure owing to member long and narrow, be in reason such as sealing state, and make both connect difficulty, and then influence works progress.
The model utility content
At the problem that prior art exists, the purpose of this utility model is to provide a kind of can connect crab-bolt by structural member long and narrow, that its closed position is used.
For achieving the above object, the utility model structural member connects crab-bolt, comprises tapered cup nut, sleeve and screw; Wherein, sleeve rear end is provided with radially boss of ring-type, this radially boss be provided with the anti-structure of revolving, barrel forward end is provided with at least one the strip opening that extends to its middle part along its axial direction; Screw inserts from sleeve rear end, and its termination, rear portion leans on the sleeve rear end end face, and its front threads end is threaded with the tapered cup nut that is positioned at barrel forward end; The tapered cup nut miner diameter end is inserted in the sleeve, along with tapered cup nut moves to termination, screw rear portion direction along the screw shaft, the anterior stack shell of sleeve is by spreading radially gradually, and the anterior stack shell of the sleeve behind the spreading and its rear end ring-type radially boss match, and are implemented in and are mounted structural gripping.
Further, the conical surface of described tapered cup nut is provided with anti-skidding reticulate pattern.
Further, described screw is a kind of in hex head screw, the socket head screw.
Further, the ring-type of described sleeve rear end radially boss is hexagon head structure or square head structure or other polygon structures or the structure that has two sides that are parallel to each other, and ring-type radially boss self promptly constitutes the described anti-structure of revolving.
The utility model connects crab-bolt by sleeve spreading end is matched with sleeve one end boss, realized installing and fixing on structural member easily, solved the problem of the connection inconvenience long and narrow on the structural member in the past, that the sealing position exists, for engineering construction provides a kind of connection set simple in structure, easy to use.

Embodiment
To shown in Figure 5, the utility model structural member connects crab-bolt, comprises tapered cup nut 1, sleeve 2 and screw 3 as Fig. 1; Sleeve 2 rear ends are provided with radially boss 22 of ring-type, radially boss 22 is provided with the anti-structure of revolving, in the practical application, ring-type radially boss 22 is hexagon head structure or square head structure or other polygon structures or the structure that has two sides that are parallel to each other, ring-type radially boss 22 self promptly constitutes and anti-revolves structure, and the preferred anti-structure 22 of revolving is the hexagonal flange in the present embodiment; Sleeve 2 front ends are provided with at least one the strip opening 21 that extends to its middle part along its axial direction, and the length of strip opening 21 can be adjusted setting according to required in the practical application; Screw 3 inserts from sleeve 2 rear ends, and its termination, rear portion leans on sleeve 2 rear end end faces, and its front threads end is threaded with the tapered cup nut 1 that is positioned at sleeve 2 front ends; Tapered cup nut 1 miner diameter end is inserted in the sleeve 2, along with tapered cup nut 1 moves to termination, screw 3 rear portion direction along screw 3 shafts, the anterior stack shells of sleeve 2 are by spreading radially gradually, the anterior stack shell of sleeve behind the spreading and its rear end ring-type radially boss 22 match, and are implemented in and are mounted structural gripping.To being provided with anti-skidding reticulate pattern 11, it prevents that skidding appears in tapered cup nut 1 in screw 3 stubborn solid processes on the surface of tapered cup nut 1.Screw 3 also can be set to outer angle head screw or interior angle screw according to the demand of practical application.
The utility model structural member connects crab-bolt and has solved in the practical application, be difficult between two structure be provided with that bolt connects or the situation of other Placements, in the practical application, only need between two fixedly connected structure of needs, through hole be set, the utility model structural member is connected crab-bolt to be inserted among the through hole, and the anti-structure of revolving that is provided with on the gripper sleeve 2, make sleeve 2 tentatively fixing, screw screw 3 again, make tapered cup nut 1 fastening sleeve 2, after further tightening tapered cup nut 1 and screw 3, tapered cup nut 1 makes the shell of sleeve 2 along its strip opening 21 spreadings, the shell of spreading and anti-revolving form two members that clamp mutually between the structure like this, make structure clamped fixing.
