Abstract
The invention relates to a cross fastener used on a scaffold in the construction industry. The traditional building fastener can not be detached from bolts and nuts, and is difficult to disassemble due to rusting when being completed every time. The quick cross fastener is free from bolts and nuts and comprises an upper cover, a wedge, a vertical rod clip and the like. The method is characterized in that: the upper cover can press the cross rod and clamp the vertical rod; the wedge can support the cross rod and wedge the vertical rod. The joint of the vertical rod clip and the wedge is an inverted wedge with a small upper part and a big lower part. When knocking the upper cover with the lifting head, each part of the integral fastener is tightened more and more.
Description
The present invention is a kind of fastener that is used for builing industry scaffold cross bearing.It is characterized in that removing the bolt on the conventional fastener, nut, installed and removed very convenient.
Traditional scaffold clasp all has bolt, nut, owing to be subjected to wind and weather for a long time, is easy to get rusty in actual use.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.The workpeople have to remove it devastatingly when running into the fastener that at all can't dismantle, makes it to scrap.Soak, scrub with kerosene again before each the repeated use, tapping again, silk rolling, otherwise just can't use.
The Patent scaffold company of N.J. once developed a kind of new type scaffold fastener without bolt, nut, shown in figure (1), this fastener need weld octal forging steel ring on montant, need the grooving punching on the cross bar, inserts fixing then with two wedge shape annexes.(seeing 70 pages of 4 phases of " Shanghai the second light industry bureau " nineteen eighty-three).This fastener makes the tie point on cross bar and the montant all fixing, can not adapt to the flexible and changeable built mode of Building Trade in China.
In order to design a kind of new type scaffold fastener of suitable China's national situation, the present invention must solve following problem:
1, in order to make fastener not be afraid of general getting rusty, must remove bolt, nut.
2, safe and reliable, press tighter and tighter when requiring overall structure stressed.
3, simple in structure, install and remove quick and convenient.
According to above problem, technical solution of the present invention is shown in figure (2); Design montant (6) with loam cake (1), chock (12) etc. and be the fast cruciform fastening for falsework of its feature.Loam cake (1) promptly has the cambered surface (2) that can push down cross bar, has the shape (3) that is similar to fork can block montant again.The upper part of chock (12) has cambered surface (13) but supporting bar, the chock of lower part (10) but wedging montant again.Connect with pin (4) between loam cake (1) and the chock (12).The clamp (19) that the band angle is arranged on the chock (12) is installed with pin (8) in the slotted hole (9) and montant clamp (6) links together.Montant clamp (6) is made of two and half garden bodies, uses pin (5) to connect therebetween.Half garden body and chock (12) junction be shaped as up-small and down-big inversion wedge shape (11), two slotted holes are arranged above, the upper end of one of them slotted hole forms bigger hole, garden (7).Should there be suitable gap f the upper end of chock (12) with montant when whole fastener assembling is used, but the lower end (10) of chock (12) is near montant.
Use the operating principle and the method for operating of the lucid and lively fast cruciform fastening for falsework of figure now, shown in figure (3); Earlier montant clamp (6) is buckled on the montant during use, then pin (5) is passed hole, garden (7) bigger on the half garden body, again cross bar is snapped between the cambered surface (2) (13) on loam cake (1) and the chock (12), cross bar is pushed, chock (12) is inserted between pin (5) and the montant, knock loam cake (1) with youth's head at last and make chock (12) wedging, this moment, the stress point of chock (12) and loam cake (1) was F

3Shown in figure (4).Because gapped f makes loam cake (1) produce the power that rotation presses down, press cross bar more tight simultaneously as pliers.Again because the half garden body of montant clamp (6) and the junction of chock (12) are up-small and down-big inversion wedge shape (11), so half garden cognition is pressed from both sides montant more tight when pin (5) lower slider.
Generally speaking, when aiming at loam cake (1) when firmly knocking, can make whole fast cruciform fastening for falsework produce following three power simultaneously with youth's head:
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 (5) can make two halfbodies of montant clamp (6) press from both sides montant more tight.
Because the angle of the slotted hole (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.
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.

Claims (4)
1, a kind of fastener that is used for builing industry scaffold cross bearing, by loam cake (1), chock (12) and montant clamp formations such as (6), it is characterized in that loam cake (1) promptly has the cambered surface (2) that can push down cross bar, have the shape (3) that is similar to fork can block montant again; The upper part of chock (12) has the cambered surface (13) can support rail, and the chock of lower part (10) again can the wedging montant; Be connected by pin (4) between loam cake (1) and the chock (12).
2, according to the fast cruciform fastening for falsework described in the claim 1, it is characterized in that a slotted hole (9) is arranged on the chock (12), the pin (8) in the slotted hole (9) links together chock (12) and montant clamp (6).
3, according to the fast cruciform fastening for falsework described in the claim 1, it is characterized in that montant clamp (6) is made up of two and half garden bodies, use pin (5) to connect therebetween, garden halfbody and chock (12) junction be shaped as up-small and down-big inversion wedge shape (11), two slotted holes are arranged above, and the upper end of one of them slotted hole forms bigger hole, garden (7).
4,, it is characterized in that should there be suitable gap f the upper end of chock (12) with montant when assembling is used, and the lower end of chock (10) are near montant according to the fast cruciform fastening for falsework described in the claim 1.
