Description
Technical field
The present invention relates to a kind of can be used for structural member connect fastening in carry out the bolt fastener erecting tools of monolateral installation, belong to civil construction project, mechanical assembly technique field.
Background technology
Current in civil construction and mechanical erection field, fastening installation requirements amount is connected to structural member large.With regard to the bolt generally used at present, when implementing to connect terminal operation to component, staff needs, simultaneously in the operation of component both sides, namely to insert nut bolt in side, then at opposite side instrument by nut screwing clamping.This method for fastening connection structure is simple, easy to operate, carry, but be only applicable in opening section component, in some special occasions, such as to closed cross-section member or inconvenience when the component that other side operates connects fastening, just cannot use this conventional bolt and nut method for fastening connection.Such as: in steel-tube construction and concrete filled steel tube, beam-column connection place, because steel pipe column is closed section, can not operate on both sides, one-sidedly can only be connected and installed, this conventional bolt and nut therefore cannot be adopted to connect fastening and carry out fastening installation.And domestic market there is no corresponding monolateral bolt product, published Patents or shank of bolt is weakened too much or bolt head stress point very few, overseas market has similar products, but above-mentioned existing patent or product are all difficult to apply larger pretension to form friction-type bolt joint at erection stage to bolt, the comprehensive mechanical property of its carrying is unsatisfactory, is very limited in Anti-quake Architectural Structure Design application.Existing a kind of split type nested monolateral securing member patent can realize this function at present, but there is the problem that inconvenience installed by split type pad.This patent can realize some split type pads and synchronously install, thus the installation effectiveness of split type nested monolateral securing member in improving greatly.
Summary of the invention
The present invention is the weak point for avoiding existing for above-mentioned prior art, a kind of split Nested-type single-side bolt fastener erecting tools is provided, thus realize the installment work of monolateral enforcement securing member, thus improve the comprehensive mechanical property of monolateral bolt carrying, also can be as required, for convenience detach, reusable.
The split type nested monolateral fastener installation tool that the present invention proposes, by rubber sleeve 3a, split type pad action bars 3b, mounting disc 4a, positioning disk 4b, slide block 5, connecting rod 6, snap bolt pad action bars 7 and hand pushing sliding block 8 are formed, split type nested unilateral bolt fastener is by snap bolt 1, split type pad 2, flat shim 10 and nut 11 are formed, described mounting disc 4a is disk, its central axis has circular hole, snap bolt action bars 7 is through described circular hole, mounting disc 4a one side is evenly distributed with chute, slide block 5 is positioned at described chute, hand pushing sliding block 8 is placed on outside snap bolt pad action bars 7, and can move around on snap bolt pad action bars 7, hand pushing sliding block 8 is by connecting rod 6 connection sliding block 5, mounting disc 4a another side is evenly distributed with positioning disk 4b, and described positioning disk 4b and chute are dislocatedly distributed, described slide block 5 is connected with split type pad action bars 3b one end, and split type pad action bars 3b is positioned at mounting disc 4a another side, the split type pad action bars 3b other end and rubber sleeve 3a interference fit, rubber sleeve 3a adopts split type pad 2 interference fit, and described snap bolt action bars 7 head is provided with screw thread and coordinates with snap bolt 1, during use, first some split type pads 2 are inserted corresponding split type pad action bars 3b, slide block 5 is moved to the inner side of mounting disc 4a upper hopper chute simultaneously, then snap bolt 1 is screwed into snap bolt action bars 7, now split type nested monolateral fastener installation tool is imported to inside installing hole 9c together with some split type pads 2 and snap bolt 1 simultaneously, the concentric locating between described mounting disc 4a and installing hole 9c, then promoting hand pushing sliding block 8 drives some slide blocks 5 and some split type pads 2 toward outside synchronous expansion, snap bolt action bars 7 of pulling back makes the bolt head of snap bolt 1 be close to split type pad 2, and keep snap bolt action bars 7 motionless, now firmly to pull back split type nested monolateral fastener installation tool, make to depart between some split type pads 2 and split type pad action bars 3b, unload split type nested monolateral fastener installation tool, flat shim 10 and nut 11 are nested in snap bolt 1 respectively, fastening nut 11, finally unload snap bolt action bars 7, thus realize the monolateral connection of structural member and fastening.
In the present invention, described slide block 5, connecting rod 6, rubber sleeve 3a, split type pad action bars 3b are identical with the quantity of split type pad 2.
In the present invention, the interference fit of rubber sleeve 3a and split type pad action bars 3b, namely rubber sleeve 3a internal diameter is slightly less than split type pad action bars 3b diameter, load in split type pad action bars 3b process at rubber sleeve 3a, rubber sleeve 3a extrudes mutually, produce larger deformation drag, make rubber sleeve 3a be stuck on split type pad action bars 3b; Rubber sleeve 3a and and split type pad 2 between interference fit, namely split type pad 2 diameter is slightly less than the external diameter of rubber sleeve 3a, insert in rubber sleeve 3a process at split type pad 2, extruding rubber sleeve 3a, thus split type pad 2 is stuck on split type pad action bars 3b tightly.
In the present invention, the end of described each positioning disk 4b is outwardly, forms ladder, several positioning disks 4b arranged concentric, forms multidiameter disc; Concentric locating between mounting disc 4a and installing hole 9c, make between installing hole 9c with mounting disc 4a concentric by the multidiameter disc of positioning disk 4b on mounting disc 4a with coordinating between installing hole 9c disc, thus guarantee in installation process, some split type pads 2 can cling on installing hole 9c wall simultaneously.
In the present invention, described hand pushing sliding block 8 adopts chain connection with connecting rod 6, and described connecting rod 6 adopts chain connection with slide block 5.
In the present invention, hand pushing sliding block 8 is with movable slider 5 to move laterally together with some split type pads 2, promote hand pushing sliding block 8 to move to installing hole 9c, hand pushing sliding block 8 drives some connecting rods 6 to move together, connecting rod 6 drives some slide blocks 5 simultaneously, slide block 5 drives split type pad action bars 3b and split type pad 2 to move laterally simultaneously, thus guarantees that some split type pads 2 synchronously can move identical distance laterally.
The design feature of the split type nested monolateral fastener installation tool of the present invention is: utilize linkage rod slide block mechanism by split type pad simultaneously toward movement outside, realizes split type pad and the less installing hole in space can be utilized to import to inside installing hole and realize launching.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1: the present invention only needs one-sided work, the fastening installation exercise of connection of bolt can be completed;
2: realize the work of split type pad integrative installation technology, substantially increase the installation effectiveness of the monolateral securing member of split type nested bolt;
3: realize, in less installing hole space, larger split type pad being installed, thus installation aperture under making carrying condition on an equal basis, can be reduced, reduce the negative effect that installing hole carries structural member, there is good mechanical property;
4: after installing split type nested bolt installation, bolt compares evenly with the stressed of split type pad, and mechanical performance compare is good;
5: the present invention can reuse erecting tools, and repeat usage is high.
