Abstract

The utility model discloses a direct plugging type scaffold, which comprises a vertical rod and a horizontal rod. The vertical rod is provided with a plurality of plug plates at intervals, four plug holes are uniformly arranged between the plug plates and the vertical rod, and the two ends of the horizontal rod are respectively welded with a plug head. The direct plugging type scaffold is characterized in that the plug heads comprise a welding plate, the lower ends of the welding plates is provided with a plug pin, the back faces of the welding plates serves as first arc-shaped surfaces, the first arc-shaped surfaces extend to the plug pins and are matched with the surface of the vertical rod, the side faces of the plug pins are formed by the first arc-shaped surfaces and second arc-shaped surface in a surrounding way, the first arc-shaped surfaces are concave surfaces, the end faces of the horizontal rod extend into the welding plates and are fixedly welded, and the surfaces of the plug holes contacted with the plug pins are matched with the second arc-shaped surfaces. Since the plug holes of the plug plates adopt arc transition, the surfaces contacted with the plug pins are increased, the stress can be uniformly distributed, the assembly can be smoothened, no cracking can be caused, and the direct plugging type scaffold is safe and reliable to use.

Description

A kind of direct insertion scaffold

Technical field

The utility model relates to the scaffold that is used for building operations, relates in particular to a kind of direct insertion scaffold.

Background technology

Scaffold is that various supports vertical and that the level transportation is set up are operated and solve in the job site for the workman.The steel tube fastener scaffold that traditional architecture beyond the region of objective existence wall decoration construction is used is to adopt fastener that steel pipe is interconnected, and makes that steel pipe can be along the horizontal and vertical rack that is built into.This scaffold uses fastener many, carries out fastening quite consuming timely on steel pipe, and labor strength is higher, and construction efficiency is lower, can only climb mobile operating owing to set up the workman on steel pipe again; The foot rest of using for the workman in the aspect operation uses bamboo to work out mostly simultaneously, all has potential safety hazard.Though the quality that the existing technical specification of security of steel tube fastener scaffold is come modular product, in work progress, often because of workman's misoperation, the fastener that causes fastening bolt to fail safe locking or use to lose efficacy, structure dress edge is random big in addition, can't guarantee that factors such as structure stress is reasonable cause security incident.

Utility model patent 200920302916.7 discloses a kind of direct insertion scaffold, comprise vertical rod and cross bar, be arranged at intervals with the button dish in the vertical rod, be evenly distributed with four locating holes on this button dish, the two ends of cross bar are respectively arranged with the plug with the corresponding snapping of locating hole, plug with the cross bar two ends when this scaffold is installed inserts in the corresponding positioning hole of buckleing on the dish, can lock as long as knock crossbar end with iron hammer, locking is more reliable when adding load on cross bar, help improving efficiency of construction, and needn't adopt the metal fastener as connector, be convenient to install, dismounting and storage, and have high degree of safety.Locating hole on the button dish of this utility model is a square hole, and stress is concentrated during use, easily produces the crack, produces potential safety hazard.

The utility model content

The utility model provides a kind of safe and reliable direct insertion scaffold at the deficiencies in the prior art.

The technical solution of the utility model is as follows: a kind of direct insertion scaffold, comprise vertical rod and cross bar, be arranged at intervals with pinboard in the described vertical rod, be uniform-distribution with four spliced eyes between pinboard and the vertical rod, plug has all been welded at the cross bar two ends, it is characterized in that: described plug comprises welded disc, the lower end of this welded disc is a latch, the back side of welded disc is first arcwall face, and first arcwall face extends into latch, and matches with the surface of vertical rod, the side of latch is surrounded by first arcwall face and second arcwall face and is formed, first arcwall face is a concave surface, and the end face of cross bar stretches into welded disc and welding is fixing, and contacted of spliced eye and latch and second arcwall face match.

Further, construction for convenience, described latch is up big and down small, constitutes tapering transition.

Compared with prior art, the spliced eye of pinboard of the present utility model adopts arc-shaped transition, increases with the contact surface of latch, thereby makes stress uniform, assembles smoothly smooth and easyly, and the phenomenon that can occur ftractureing is not safe and reliable during use.

The specific embodiment

As shown in Figure 1, direct insertion scaffold of the prior art comprises vertical rod 1, cross bar 2 and pinboard 3.Locating hole in the pinboard 3 of the prior art is a square hole, and stress is concentrated, and is easy to crack.

As shown in Figure 2, pinboard 3 of the present invention adopts arc-shaped transition, and stress is uniform, can not ftracture in the use, and is safe and reliable.

As shown in Figure 3, cross bar 2 welds together with plug 5, is inserted into then in the spliced eye 4 in the pinboard 3 that is welded in the vertical rod 1, promptly finishes installation, and is very convenient.

Fig. 4 is the schematic diagram of plug of the present invention, comprises welded disc 51, and the end face of cross bar 2 stretches into welded disc 51 and can weld fixing easily.The lower end of this welded disc 51 is a latch 52, the back side of welded disc 51 is that first arcwall face, 53, the first arcwall faces 53 extend into latch 52, and matches with the surface of vertical rod 1, the side of latch 52 is surrounded by first arcwall face 53 and second arcwall face 54 and is formed, and first arcwall face 53 is a concave surface.
