Abstract
A steel tube scaffold fastener with plum-headed bolts comprises two fastener bodies connected. Each fastener body comprises two semicircular members in butt joint. Two ends of each semicircular member are provided with a rotating connection block and a fixed connection block, respectively, both extending out. The rotating connection blocks of each fastener body are correspondingly connected in an inserted manner; a connecting bolt longitudinally penetrates the inserted connection of the rotating connection blocks. The fixed connection blocks of each fastener body are longitudinally and symmetrically attached to each other, and a connecting bolt transversely penetrates the fixed connection blocks. A plum head is arranged at one end of each connecting bolt and is connected with the connecting bolt through a hexagonal nut. The fastener bodies can be vertically fixedly connected, obliquely fixedly connected or longitudinally vertically spliced. The steel tube scaffold fastener can be used to effectively tighten connecting steel tubs and allows connection tightening torque to be detected, and safety of a scaffold is improved.
Description
Technical field
The utility model relates to the steel tube scaffold clasp with wabbler bolt, belongs to mechanical field.
Background technology
Fastener type steel pipe scaffold in indispensable status, is mainly comprised of fastener, steel pipe, base and backing plate in engineering construction instantly.Because of the convenience of its construction and installation dismounting and with low costly adopted by many engineerings (especially industrial civil building engineering).It has following three outstanding advantages:
One, bearing capacity is larger.When relevant requirements that physical dimension and the structure of scaffold meets standard, the bearing capacity of the single tube column of scaffold can reach 15kN-35kN;
Two, easy installation and removal.Scaffold clasp connects easy, thereby can adapt to building and the structure use of various planes, facade, and one time investment cost is lower, if well-designed scaffold physical dimension;
Three, good economy performance.Design of coupler scaffold processing is simple, should note improving steel pipe turnover utilization rate.Data demonstration, fastener style steel pipe frame is amounted to approximately 15 kilograms of every square metre of construction steel amounts, than other form scaffold better economies.
Yet although it uses in a large number in all kinds of engineerings instantly, the problem itself existing also can not be ignored.According to the statistics of some data, in the construction work accident causing casualties, scaffold caves in and has accounted for significant proportion.And the fastening degree of fastener is one of major reason leading to scaffold cave-in accident not.Fastener is joint steel pipe, the key of transmitting load.The scaffold safety standard > > of < < country regulation fastener Tightening moment " should not be less than 40Nm; and should not be greater than 65Nm ", " fastening bolt after installation is tightened torsional moment should adopt torque spanner inspection ", " underproof must again tightening, until qualified ".In some scaffold cave-in accidents, scaffold clasp is without the survey data of fastening degree, and this makes the bearing capacity of scaffold and stability be difficult to guarantee.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of steel tube scaffold clasp with wabbler bolt, this scaffold clasp reaches screw-down torque by twisting into two parts wabbler check fastener, and check is convenient, assay is reliable, improves the safety of scaffold clasp.
Steel tube scaffold clasp with wabbler bolt, the fastener body that comprises two connections, each fastener body all has the semicircular body of two docking, the two ends of each semicircular body stretch out respectively form be rotatably connected platform be fixedly connected with platform, two corresponding pegging graft of the platform that is rotatably connected of described each fastener body, and longitudinally run through connecting bolt in the part of pegging graft, two are fixedly connected with the longitudinal symmetry of platform and are adjacent to, and be laterally penetrated with connecting bolt, one end of connecting bolt is provided with wabbler, between wabbler and connecting bolt, by hex nut, is connected.
Two one of platforms that are rotatably connected of described each fastener body stretch out for upper and lower both ends horizontal, middle vacancy, another stretches out for centre, upper and lower two ends vacancy, the extension of two platforms that are rotatably connected and the corresponding grafting of vacancy part, connecting bolt penetrates the center of extension, and two semicircular body of each fastener body all can be rotated around connecting bolt.
Described two fastener bodies are vertically fixedly connected with, and the outer middle side part square crossing of two semicircular body is welded and fixed, and runs through connecting bolt, and the wabbler on two fastener bodies is all positioned at the side away from connecting bolt.
Described two fastener bodies tilt to be fixedly connected with, and the outer middle side part inclination cross weld of two semicircular body is fixed, and runs through connecting bolt, and the wabbler on two fastener bodies is all positioned at the side away from connecting bolt.
Described two fastener bodies longitudinally vertical splicing are fixing, and the end of the semicircular body being mutually adjacent to is welded and fixed.
The utility model, compact conformation, easy to use, during use, be fixedly connected with platform and separate, two semicircular body of each fastener body, around the connecting bolt Unscrew that runs through the platform that is rotatably connected, are placed in fastener body by being connected fixing steel pipe, two semicircular body of rotary closing, the platform that is fixedly connected with of two semicircular body is adjacent to, and runs through connecting bolt being fixedly connected with on platform, and one end of connecting bolt connects wabbler by hex nut, the wabbler that screws up with a wrench, until wabbler is twisted into two parts.According to the torsional strain Lik-Sang presetting, produce wabbler, wabbler in use, is twisted and is reached corresponding screw-down torque, and wabbler will break.The utility model, when being twisted off, wabbler just illustrates that fastener body has reached the screw-down torque requiring, easily the end, distinguishes that steel pipe is tightened, reach standards for safe use, greatly reduce inspection cost and the time of steel tube scaffold clasp, improve construction and the efficiency of management, better the end, guarantees the safety of scaffold, avoided because of fastener Rig up error, or the scaffold cave-in accident that causes not of screw-down torque.
