Abstract

A scaffold welding-free cross rod comprises openings, upper plug-pin square holes and lower plug-pin square holes. Two ends of the scaffold welding-free cross rod are both in an oblate duckbilled shape, an upper opening and a corresponding lower opening are arranged in flat surfaces of each duckbill-shaped end, one upper plug-pin square hole is arranged in a side vertical face of each duckbill-shaped end, one lower plug-pin square hole is arranged in the other side vertical face of each duckbill-shaped end, and an opening of the upper plug-pin square hole corresponds to an opening of the lower plug-pin square hole. The scaffold welding-free cross rod has the advantages that no other parts are needed, and only a steel tube is needed to be processed to a cross rod piece; no welding process is needed; manufacturing process of the cross rod is simpler and more convenient; processing cost is lowered; weight is reduced; and potential safety hazards caused by welding defects of a traditional cross rod assembly are avoided.

Description

A kind of scaffold exempts to weld cross bar

Technical field

The utility model relates to a kind of scaffold, and a kind of in particularly a kind of socket joint type dish button scaffold exempts to weld cross bar.

Background technology

Scaffold was used widely in building already, and mostly builing industry scaffold commonly used is fastener type, bowl fastening type or gate-type etc. at present.Socket joint type dish button scaffold is in recent years from the domestic a kind of new type scaffold support system of external introducing; Its structure rationally, high, the safety and stability of supporting capacity, easy accessibility and reduce the construction integrated cost; Through practical applications in the past few years, admitted by the domestic user gradually.The cross bar of present this scaffold is the assembly that adopts two casting terminations and steel pipe to be welded, but needs manual work to weld, and uses very inconvenient.

The utility model content

The utility model technical problem to be solved provides a kind of scaffold and exempts to weld cross bar.

For solving the problems of the technologies described above, the following mode of the utility model realizes: a kind of scaffold exempts to weld cross bar, comprises gap, goes up latch square hole and following latch square hole; The two ends that said scaffold exempts to weld cross bar are oblate duckbill shape, on the flat horizontal surface of said duckbilled, offer two upper and lower corresponding gap; A side elevation of said duckbilled have one said on the latch square hole, have a said latch square hole down at the opposite side facade of said duckbilled, saidly go up latch square hole and the said corresponding setting in aperture of latch square hole down.

The good effect of the utility model is: (1) does not need other part, only has rail bar member with steel pipe of one's own through processing; (2) do not need welding; (3) the cross bar manufacture craft is more easy; (4) cut down finished cost; (5) weight reduction; (6) avoid traditional cross bar assembly to cause construction safety hidden danger because of weld defect.

Description of drawings

Fig. 1 exempts to weld a wherein end sketch map of cross bar A for the utility model is said.

Fig. 2 exempts to weld for the utility model is said that cross bar (A1 and totally two of A2) is buckled B with the dish on the vertical rod D and latch C is connected side schematic view.

Fig. 3 exempts to weld cross bar (totally four of A1, A2, A3 and A4) and the dish on the vertical rod D and buckles the vertical view that B and latch C are connected for the utility model is said.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

As shown in Figure 1, the described a kind of scaffold of the utility model exempts to weld cross bar, comprises gap 1, goes up latch square hole 2 and following latch square hole 3.

The end that to exempt to weld cross bar A earlier is pressed into oblate duckbill shape, on the flat horizontal surface of said duckbilled, offers two upper and lower corresponding gap 1.Side elevation at said duckbilled has latch square hole 2 on, has a following latch square hole 3, last latch square hole 2 and the corresponding setting in the aperture of following latch square hole 3 at the opposite side facade of said duckbilled.The two-end structure of exempting to weld cross bar A is identical.

As shown in Figure 2, the utility model also comprises vertical rod D, dish button B and latch C.During use, will coil button B earlier and be inserted on the vertical rod D, again 2 gap 1 insertion dishes of exempting to weld cross bar A one end buckled on the B, after latch C is inserted into latch square hole 2 and following latch square hole 3 from top to bottom, thereby two end and vertical rod D that exempt to weld cross bar A are fixed.

As shown in Figure 3, the utility model can also be used for exempting to weld being fixedly connected of cross bar A and vertical rod D with 4.Method of attachment is the same.

The good effect of the utility model is: the utility model is horizontal connection and the support that is used for socket joint type dish button scaffold support system, and (1) does not need other part, only has rail bar member with steel pipe of one's own through processing; (2) do not need welding; (3) the cross bar manufacture craft is more easy; (4) cut down finished cost; (5) weight reduction; (6) avoid traditional cross bar assembly to cause construction safety hidden danger because of weld defect.
