Abstract
The present invention relates to a cruciform fastener utilized on a scaffold in construction industry. All traditional building fasteners need to be provided with screw bolts and nuts which are difficult to disassemble because of rustiness during completion every time. The fast cruciform fastener is removed from the screw bolts and the nuts and is composed of an upper cover, a wedge, a vertical rod clamp, etc. The fast cruciform fastener is characterized in that the upper cover not only can press against a horizontal rod but also can clamp a vertical rod, the wedge not only can support the horizontal rod but also can tighten the vertical rod in a wedged mode, and the connecting point of the vertical rod clamp and the wedge form a wedge shape of which the upper part is large and the lower part is small. All the parts of the integral fastener can be tight more and more by using a hammer to knock the upper cover.
Description
The present invention relates to a kind of outer anchor clamps of builing industry scaffold steel pipe cross handing-over that are used for, particularly relate to the quickly assembled and disassembled cruciform fastening for falsework that a kind of nothing with self-locking function is threaded.
Traditional scaffold clasp (for example, United States Patent (USP) 2233458 disclosed fasteners) all has bolt to connect, in actual use owing to be subjected to wind and weather for a long time; Be easy to get rusty.Again because very careful screw thread is arranged, thus there is iron mold just to bring very big difficulty slightly to dismounting, even can't dismantle at all.When running into the fastener that at all can't dismantle, the workpeople have to remove it devastatingly, makes it to scrap.Before each the repeated use again with kerosene soak, scrub, tapping and silk rolling again, otherwise just can't use.
The patent scaffold company of N.J. once developed a kind of new type scaffold fastener without bolt, nut, as shown in Figure 1, this fastener need weld octal forging steel ring on montant, need the grooving punching on the cross bar, insert fixing (seeing 70 pages of 4 phases of " Shanghai the second light industry bureau " nineteen eighty-three) with two wedge shape annexes then.The cross bar of this fastener and the tie point on the montant are all fixing, can not adapt to the flexible and changeable built mode of builing industry.
The purpose of this invention is to provide a kind of without scaffold clasp bolton, that have quick mounting or dismounting performance and self-locking function.
Purpose of the present invention can be achieved by following embodiment.A kind of cruciform fastening for falsework that is used for the steel pipe cross junction of builing industry scaffold has a montant clamp; A chock, this chock is hinged by pin and montant clamp, but and the bottom of this chock the cambered surface of one wedging montant is arranged; Chock top can support rail cambered surface; It is characterized in that:
A. said montant clamp comprises two with the hinged semicircular body of pin; Inversion wedge-riser flange in semicircular body and said chock hinged place has the slotted hole that slides for a boss pin on each flange, the upper end of a slotted hole in said slotted hole has in one through the circular hole greater than boss pin boss external diameter;
B. said chock has a slotted hole chute, and the slotted hole that said boss pin passes on said slotted hole chute and the flange links together a semicircular body of chock and montant clamp slidably;
C. the cambered surface of said support rail is hinged by a pin and a loam cake, and said loam cake has a cambered surface and the clamp forks of blocking vertical tube that can push down cross bar;
D. the cambered surface of said support rail and the loam cake hinged place plane apart from chock against vertical tube has certain distance.
The advantage of above fast cruciform fastening for falsework is: owing to removed bolt, nut, be not afraid of general getting rusty.Safe and reliable, press tighter and tighter when overall structure is stressed.Simple in structure, installing/dismounting is quick and convenient.
Fig. 1 is the schematic diagram of the novel fastener of United States Patent (USP) scaffold company manufacturing.
Fig. 2 is the user mode phantom drawing of cruciform fastening for falsework of the present invention.
Fig. 3 is the phantom drawing of cruciform fastening for falsework of the present invention when being in preparation work dress attitude.
Fig. 4 is that cruciform fastening for falsework of the present invention 3 when user mode are subjected to the force direction schematic diagram.
Below in conjunction with accompanying drawing the present invention is described in more detail.
Referring to Fig. 2, cruciform fastening for falsework of the present invention has a montant clamp 6, this clamp 6 is made of by pin 5 is hinged two semicircular bodies, on each semicircular body, has a up-small and down-big inversion wedge-riser flange 11, have on flange 11 for the slotted hole 14 that slides with the hinged boss pin 8 of chock 12, slotted hole 14 upper ends of a flange 11 have the circular hole 7 of an internal diameter greater than the boss external diameter of boss pin 8 therein.
Have a slotted hole chute 9 on chock 12, boss pin 8 passes slotted hole chute 9 and slotted hole 14 semicircular body (this semicircular body does not have circular hole 7) and the chock 12 of montant clamp is linked together slidably.
Obviously, boss pin 8 matches the diameter of part with slotted hole chute 9 and slotted hole 14 should be less than the width of chute 9 and slotted hole 14, and the external diameter of the projection section at boss pin two ends should be greater than the width of chute 9 and slotted hole 14, but less than the internal diameter in hole 7.
The cambered surface 13 that has a support rail in the upper end of chock 12, cambered surface 13 is hinged by a pin 4 and a loam cake 1, has a cambered surface 2 and the clamp forks 3 that can block vertical tube that can push down cross bar on loam cake 1.Has a cambered surface that can compress montant in the bottom 10 of chock 12.
Referring to Fig. 4, has certain distance f on the cambered surface 13 and the plane of loam cake 1 hinged place of support rail apart from chock against vertical tube.
Use the operating principle and the method for operating of the lucid and lively fast cruciform fastening for falsework of figure now, as shown in Figure 3; Earlier montant clamp 6 is buckled on the montant during use, then boss pin 8 is passed the big circular hole 7 of hinge on the semicircular body, again cross bar is snapped between the cambered surface 13 on loam cake 1 and the chock 12, cross bar is pushed, chock 12 is inserted between pin 8 and the montant, knock loam cake 1 with youth's head at last and make chock 12 wedgings, this moment, the stress point of chock 12 and loam cake 1 was F
1, F
2And F
3, as shown in Figure 4.Owing to the existence that has apart from f, make loam cake 1 produce the power that rotation presses down simultaneously, press cross bar more tight as pliers.Again because the semicircular body of montant clamp 6 is up-small and down-big inversion shape flange 11 with the junction of chock 12, so when pin 8 during to downslide, semicircular body can be pressed from both sides montant more tight.
Generally speaking, when firmly knocking, can make whole fast cruciform fastening for falsework produce following three power simultaneously with youth's head aligning loam cake 1:
1, wedge is tight more more with montant for chock 12.
2, loam cake 1 is pressed cross bar more tight.
3, the downslide of pin 8 can make two semicircular body of montant clamp 6 press from both sides montant more tight.
Because the angle of the slotted hole chute 9 on the chock 12 is less than angle of friction, thus whole fast cruciform fastening for falsework can not become flexible voluntarily by after the wedging, also only can be more and more tighter when loaded work piece.
Only need with the counter from bottom to top chock 12 that strikes of youth's head during the dismounting fast cruciform fastening for falsework, whole fastener can become flexible and unload.
