Abstract

The utility model relates to an efficient clip for the joint of the steel tube scaffold of the tall building for the construction work, comprising web plates, support frames, hasps, clip rings, etc. During the process of the fastening, the action for locking a hole can be finished for one time; compared with the prior technology, the utility model can improve the work efficiency for 5 times; The utility model adopts the mechanism safety and the self locking of the hasp for overcoming the defects of personal factors. The utility model has the advantages of compact structure, low cost, and high safety, and the utility model can be widely suitable for construction sites. In particular, the utility model can be used for the steel tube scaffolds of the tall building.

Description

Building scaffold efficient clip

The utility model relates to the efficient fastener that uses on the steel pipe scaffold contact in a kind of building operations.

At present, the fastener that the steel pipe scaffold contact uses in building operations is to screw two web fasteners with bolt nut, uses the easy stripped thread inefficacy of back bolt thread several times, and reusability is poor; Simultaneously because people's subjective factor, if any muscle power strong, have muscle power weak, when just going to work with situation such as close on when coming off duty, to screwing fastener, just lack absolute reliability, influence construction safety.

The purpose of this utility model is to provide a kind of building scaffold efficient fastener, and it can be effectively after finishing the clamping steel pipe scaffold, the hasp self-locking, and can form related locking together with cam.

The purpose of this utility model is achieved in that

The efficient fastener of a kind of building scaffold, form by long rivet (1), web (2), support (3), hasp (4), short rivet (6) and clasp (10) etc., as shown in Figure 1 and Figure 2, fluted (7a, the 7b) of an end and the protruding hook (8a, 8b) that it is characterized in that web (2a, 2b); One end of support (3a, 3b) has short rivet (6a, 6b) to connect hasp (4a, 4b), and hasp hole (5a, 5b) is arranged on the hasp, and clasp (10a, 10b) is through respectively in the hasp hole (5a, 5b), can freely rotate; The other end of web (2a, 2b) is cam (9a, 9b).

Web (2) and support (3) are to water with ductile iron or malleable cast iron casting to form.Clasp (10) is swaged into by a diameter 0.4-1 centimetre round steel.

When scaffolding steel pipe penetrates fastener hole (11a), clasp (10a) is placed on groove (7a) locates, firmly hasp (4a) is pressed to web (2a) and draw close, because clasp (10a) effect, promptly the steel pipe automatic locking; When vertically to steel pipe penetrates fastener hole (11b), clasp (10b) is placed on groove (7b) locates, firmly hasp (4a) is pressed to web (2b) and draw close because clasp (10b) acts on, vertical to also automatic locking of steel pipe.

Compare with original technology, the utility model has the advantages that:

Owing to adopt hasp (4) and clasp (10) securing bracket (3) and web (2), the lockhole action is once finished, and improves 5 times of work efficiency than original technology with bolton, simultaneously, considers that in design clasp tension web gives the distortion situation of tight power and web; In addition, the utility model is mechanism's insurance, has overcome the shortcoming of human factor.

Embodiment

Water web (2), support (3) and hasp (4) with the malleable cast iron casting, be swaged into clasp (10), form with rivet (1,6) installation by Fig. 1 and Fig. 2 with diameter 0.6 round steel.In fastening process, during as the relative tendency toward sliding of generation fastener,, make fastener rob tighter and tighter because cam (9) has the effect of rotation trend, make fastening being perfectly safe reliably.

Claims

1, the efficient fastener that uses on the steel pipe scaffold contact in a kind of building operations, form by long rivet (1), web (2), support (3), hasp (4), short rivet (6) and clasp (10), it is characterized in that fluted (7a, the 7b) of an end and the protruding hook (8a, 8b) of web (2a, 2b); One end of support (3a, 3b) has short rivet (6a, 6b) to connect hasp (4a, 4b), and hasp hole (5a, 5b) is arranged on the hasp, and clasp (10a, 10b) is through respectively in the hasp hole (5a, 5b), can freely rotate; The other end of web (2a, 2b) is cam (9a, 9b).

2, efficient fastener according to claim 1 is characterized in that web (2) and support (3) are to water with ductile iron or malleable cast iron casting to form.

3, efficient fastener according to claim 1 is characterized in that clasp (10) is swaged into by a diameter 0.4-1 centimetre round steel.
