Abstract

The utility model relates to the clamping apparatus of a falsework, comprising a base, a moving flap hinged on the base and a clamping device clamping the base and the moving flap, wherein, the clamping device is provided with a locking block; a rotary inclined plane is arranged on the locking block; the rotary inclined plane is engaged with a flange part on the moving flap; the height differences of the rotary inclined plane is used to realize the clamp, simultaneously a left and a right mechanisms are adopted to cause the helix angle to be reduce by half (less than 3 DEG), so the utility model is safe and does not slow the clamp.

Description

Clamping apparatus of falsework

The utility model relates to a kind of anchor clamps of being connected between the steel pipe of builing industry scaffold of being used for, and particularly relates to a kind of quickly assembled and disassembled anchor clamps with auto-lock function.

Traditional scaffold clamp mostly adopts bolt to connect, and in actual use, because the duration of a building is all very long, anchor clamps are subjected to wind and weather for a long time.Make it to be easy to get rusty.Because the screw thread of bolt is very thin, there is iron mold to bring very big difficulty slightly, even can't dismantles again to dismounting.When running into situation about can't dismantle, the workpeople have to remove it devastatingly, thereby makes it to scrap.And before each the repeated use, soak, scrub with kerosene again, tapping and silk rolling again, otherwise just can't use.In addition, when mounting or dismounting, nut must rotate more than two weeks, and it is very inconvenient to install and remove.

The purpose of this utility model provides a kind ofly is not afraid of rust, safety, installs and removes scaffold clamp rapidly.

Solution of the present utility model is, the self-lock mechanism of Worm wheel transmission mechanism is applied on the existing anchor clamps that adopt bolted scaffold.Specifically, it is the cross section that the lock dog in the clamping device of anchor clamps is likened to worm screw, flange portion on the anchor clamps sheet alive is likened to the tooth of worm gear, but well-known Worm gear mechanism self-locking is unreliable, meeting " the slow button " can not be used after being vibrated as the model machine of preceding application (application number 93101670.3), it is left and right each this device of cover that the utility model has adopted bilateral mechanism, thereby make lead angle reduce 1/2(less than 3 °) guaranteed not " slow button ", improve safety, also guaranteed the amount of feeding of horizontal locking simultaneously.

The utility model has removed careful screw connection structure, therefore is not afraid of general getting rusty, and owing to adopt Worm wheel transmission mechanism, thereby have the characteristics rapidly of installing and removing.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a front view of the present utility model.

Referring to accompanying drawing, it is the same substantially with old-fashioned fastener that inventive point of the present utility model is gone up other parts at " bolt ", and 21 and 3 is two steel pipes of snapping.Free end at the sheet 2 of living is shaped on flange 4, in the left side of flange 4 baffle ring 5 is arranged.Clamping device 6 comprises bottom lock dog 7, neck 8, lock dog 9, manoeuvre portion 10 successively.During use, can send into back being connected to clamping device 6 from right part and decide on the body 1 from breach 12 introducings.Screwing manoeuvre portion 10 again gets final product.Then left and right stream oriented device can be symmetrical fully except that opening 12 and baffle ring 5 if clamping device 6 is for disome combination (as welding), and neck 8 also needn't become warp.Be shaped on respectively on the lock dog 7,9 and spin canting or the curved surface of deciding body 1, flange inclined-plane on the sheet 2 of living matches, rotation inclination angles, two inclined-planes (being lead angle) can be as small as below 3 °, are shaped on helicoid or the straight inclined-plane that matches with the above-mentioned surfaces of revolution respectively in flange portion 11,4.In order to guarantee that clamping device 6 does not withdraw from from breach 12, and in order to simplify the technology ad hoc baffle ring 5 that reduces cost, apparent the utility model is suitable for the fastener of any specification and model.

Claims

1, a kind of scaffold clamp is by deciding body, and moving plate, clamping device three parts are formed, and it is characterized in that:

(1) clamping device 6 is made up of bottom lock dog 7, neck 8, lock dog 9, manoeuvre portion 10;

(2) decide to be shaped on opening 12 on the body and on the flange of termination, be shaped on inclined-plane or the curved surface 11 that matches with the angle of lock dog 7;

(3) be shaped on baffle ring 5 on the moving plate, and on the flange of termination, be shaped on inclined-plane or the curved surface 4 that matches with lock dog 9 angles.
