Description
Technical field
The present invention relates to a kind of bolt fastener for carrying out monolateral installation in workpiece, belonging to Building technology and Automatic manual transmission field.
Background technique
With regard to the plain bolt be made up of screw rod and nut generally used at present, when carrying out terminal operation, need insert screw rod and binding nut, then tightened by nut at opposite side instrument in side, installation requirement installation personnel is simultaneously in the operation of component both sides.But relative to the installation of more common opening section component, for such as closed cross-section member and the component being inconvenient to touch wherein one side, this bolt generally used is inconvenient in use.As at the place such as concrete filled steel tube, beam-column connection, because column section mostly is closed section, plain bolt can not operate on both sides, and therefore commonsense method cannot be installed.Common expansion one-way bolt is because being difficult to the applying realizing bolt pretightening, and fastening effect also cannot reach designing requirement under larger load.And the reserved required precision of punching bolt-for-bolt hole of the prior art is high especially, in-site installation difficulty is large, and is difficult to application at side column and corner post Nodes.And in existing monolateral bolt, be not suitable for longspan or large load structure, and need more complicated setting tool and more loaded down with trivial details installation steps.
Summary of the invention
technical problem:the invention provides a kind of can overcome existing bolt can not monolateral fastening deficiency, the umbrella-type for the monolateral installation of component improving bolton effect launches bolt fastener.
technological scheme:umbrella-type for the monolateral installation of component of the present invention launches bolt fastener, comprise the screw rod that one end is provided with supporting member, be enclosed within the sleeve that the intermediate bar of described screw rod is external, the screw-in nut of the screw rod the other end is arranged on by screw thread, connect the umbrella-type be arranged between described supporting member and sleeve and launch supporting component, described sleeve closes on the outer installment screwing in nut one end screw thread, the other end closes on supporting member and is provided with the mounting groove of quill to equally distributed more than three or three, described umbrella-type is launched supporting component and is made up of the first strut be hinged and the second strut, hinged rotating shaft between described first strut and the second strut and quill are to vertical, first strut one end is arranged on supporting member by bearing pin, described second strut to be arranged in mounting groove and to be arranged on sleeve by bearing pin.
In preferred version of the present invention, screw rod is installed the end screwing in nut one end and be provided with wabbler.
In preferred version of the present invention, sleeve closes on the screw thread of the outer installment screwing in nut one end for clamp structure.
In preferred version of the present invention, when umbrella-type expansion supporting component is in non-open configuration, the first strut and the second strut are positioned on same axis, and the first strut is contained in mounting groove completely, and sleeve is consistent with the external diameter of supporting member.
The structural feature of unilateral bolt fastener of the present invention is: be all respectively arranged with joint in the both sides at the two ends of described support lobe, and formed mechanism with bearing pin, pulling-on piece etc. and bolt body, with mechanism principle realize interlock and fastening.
beneficial effect:compared with prior art, the present invention has the following advantages:
1, the present invention only needs, at side construction bolt, to achieve the one-side operation of bolt;
2, in the present invention, screw rod leading portion supporting member supports after lobe struts, it is vertical with the surface of contact of installation component, is not easy to be pulled out, good fastening effect under load action;
3, when the invention process is installed, only need use instrument on nut, apply suitable pretightening force, can complete and launch and reach fastening effect, operation and plain bolt are as good as, and kit is simple.After installation, node reliability is high, effectively can improve ultimate bearing capacity of joints;
4, the present invention meets Design Of Steel Structure requirement completely, can well be applied to the connection of steel structure node connection and other closed sections, especially concrete filled steel tube;
5, compared with the existing monolateral clamping bolt utilizing special material, do not need to use special material, do not rely on material deformation and form support, stopped fatigue of materials and be out of shape the hidden danger brought further;
6, mechanism supports is directly stressed, more reliable when being applied to the higher use occasion of requirement of strength.

Embodiment
Below in conjunction with Figure of description and embodiment, technological scheme of the present invention is described in further details.
Embodiment: in the present embodiment, the vibrational power flow of unilateral bolt fastener is:
As schemed shown in lA and figure lB, end spaced set has the screw rod 1 of pin groove and coordinates the sleeve 2 of screw rod, described screw rod rear portion be provided with screw in screw thread that nut 4 matches, screw rod stage casing is polished rod, screw rod leading portion arranges supporting member 1a; Sleeve 2 rear is provided with the screw section of matching with fastening nut 4a, sleeve is arranged mounting groove to coordinate placement first strut 3a and the second strut 3b; Described supporting member 1a spaced set has pin groove and coordinates bearing pin to arrange three altogether can the described first strut 3a that struts of umbrella shape, the madial wall of described first strut 3a is triangular ramp face, supports slope when lobe launches and makes supporting member 1a point diameter be greater than sleeve 2 external diameter and tail diameter; When fastening piece is installed, in a contracted state, described supporting member 1a passes completely through installation hole, now screws the described screw-in nut 4 on inner screw, screws by screwing in nut 4 described in inner screw, drives described sleeve 2 to move to described supporting member 1a direction; Because of described first strut 3a predetermined angle, therefore promote multiple described first strut 3a in described sleeve 2 movement process is that umbrella shape struts simultaneously.Now supporting portion leading portion is greater than aperture, is formed and supports, form deployed condition in supporting portion.Now screw the fastening nut 4a in described bush whorl portion, apply suitable pretightening force, can realize monolateral fastening by this.The present invention only needs the bolt that can complete closed section in side to install, and can realize the one-side operation of bolt.
As schemed shown in lA, Figure 1B, supporting head part grading interval is provided with pin groove, and to connect support lobe, supporting lobe can rotate around bearing pin; Sleeve part connects support lobe with bearing pin and pulling-on piece, makes supporting member, support lobe, sleeve become a double-action mechanism.
As shown in Figure 2 A and 2 B, inner screw coordinates nut can move with the rear side of moving sleeve towards screw rod, be slope owing to supporting the madial wall of lobe, 3 support lobes can be that umbrella shape outwards struts by the serial verb construction consisted of with support lobe bearing pin and pulling-on piece.
The present embodiment comprises the following steps:
1, bolt is passed reserving hole, accurate contraposition;
2, be firmly connected with sleeve with mounting fixture, tighten screw-in nut, making three to support lobe is that umbrella shape outwards struts;
3, be firmly connected with screw rod with mounting fixture, tighten fastening nut, fastening by applying suitable pretightening force, complete fixing.
Above-described embodiment is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention; some improvement and equivalent replacement can also be made; these improve the claims in the present invention and are equal to the technological scheme after replacing, and all fall into protection scope of the present invention.
