Abstract
The utility model relates to a scaffold, which comprises upright rods and transverse rods. The scaffold is characterized in that connecting parts for being connected with the transverse rods are arranged on the upright rods according to a certain spacing, a plurality of trapezoid bumps are evenly distributed on the peripheral surface of each connecting part, trapezoid grooves arranged on the heads of the transverse rods are in mortise joint with the trapezoid bumps, and screw parts preventing the transverse rods from falling out are arranged on the upper portions of the connecting parts. The scaffold has the advantages of not only simple structure, speedy assembly and disassembly and convenient use, but also safe and stable use and high repeated use rate.
Description
Technical field
The utility model relates to a kind of novel scaffold.
Background technology
At present, builing industry is extensive use of fastener type steel pipe scaffold, though that this conventional fastener formula steel pipe scaffold has is simple in structure, fast assembling and disassembling, characteristics such as easy to use, it also has the defective in the design, make progress easily as steel pipe, thereby brought huge potential safety hazard to use.
Summary of the invention
The utility model relates to a kind of scaffold, and this scaffold is not only simple in structure, fast assembling and disassembling, easy to use, and safe in utilization stable, repeat usage is high.
The utility model scaffold, comprise vertical rod and cross bar, it is characterized in that: described vertical rod is provided with the connector that connects cross bar, the all side surfaces of described connector evenly are laid with some trapezoidal projections, described yardarm head is provided with and the trapezoidal projection trapezoidal groove of joggle mutually, and described connector top is arranged with and prevents cross bar the spiral shell spare of deviating from that makes progress.
The utility model prevents cross bar the spiral shell spare of deviating from that makes progress by being arranged with on connector top, thereby the cross bar that is connected on the connector can not deviate from, and has avoided the potential safety hazard of using.
Connector of the present utility model not only can effectively connect all rod members, and each center line of the bar intersects at a bit, whole axially loadeds, and no subsidiary stress, mechanical property is good, connects reliably the scaffold good integrity of composition.Simultaneously, connector of the present utility model has good strength and stiffness, and vertical rod be connected with cross bar can be because of wherein a cross bar and vertical rod continuous damage cause the continuous damage of vertical rod and other cross bar.The utility model is suitable for setting up civil engineering structure construction and the dual-purpose external scaffolding of fitment operation, can also be a kind of multifunction scaffold as the bracing frame of template and other temporary platform supports etc.

Fig. 4 is the utility model user mode organigram.
The specific embodiment
The utility model scaffold, comprise vertical rod 1 and cross bar 2, vertical rod 1 is provided with the connector 3 that connects cross bar 2, connector 3 all side surfaces evenly are laid with some trapezoidal projections 4, cross bar 2 termination portions are provided with and the trapezoidal projection 4 trapezoidal groove joint 5 of joggle mutually, and connector 3 tops are provided with the spiral shell spare 6 that prevents that cross bar from making progress and.
In order to connect the transverse bar in four orientation all around, connector 3 all side surfaces are evenly equipped with 4 trapezoidal projections 4.
For the ease of screwing of spiral shell spare, above-mentioned spiral shell spare 6 is provided with the turn that two projections 7 are convenient to spiral shell spare.
When the utility model scaffold is made, just weld groove joint 5, connector 3 is fixed in the vertical rod 1 at a certain distance (can welds), be convenient to on-the-spot the connection at cross bar 2 two ends of certain specification length.During on-the-spot the connection, earlier spiral shell spare 6 is pulled upwardly (upwards sliding) along vertical rod 1, all directions cross bar 2 end trapezoidal groove joints 5 are aimed at the back to be inserted with the trapezoidal projection 4 on the connector 3, subsequently spiral shell spare 6 is slided along vertical rod 1, and be connected to compress cross bar 2 end recesses joints 5 with connector 3 upper end screw threads, projection 7 to whole screw threads in spiral shell spare 6 outsides that pound with a hammer screw to reach and compress the cross bar requirement.Adopt this connected mode, cross bar 2 adopts the upright horizontal fourth of the twelve Earthly Branches of tenon socket joint to be threaded with vertical rod 1, and cross bar 2 can not break away from vertical rod 1 under horizontal force action; Simultaneously, the tenon fourth of the twelve Earthly Branches is shaped as up-small and down-big, can guarantee that cross bar 2 can bear load action straight down; And if cross bar 2 is subjected to load action straight up, then can be connected with connector 3 upper end screw threads by spiral shell spare 6 in the vertical rod 1 and pushes down cross bar 2 end recesses joints 5, make cross bar 2 can not come off.
The utility model scaffold is not only simple in structure, fast assembling and disassembling, easy to use, and safe in utilization stable, repeat usage is high.
Claims (4)
