Abstract

The utility model relates to a scaffold connecting mechanism, in particular to a novel scaffold connecting mechanism for horizontal tenon vertical mortise socket threaded connection, which comprises a vertical rod and a horizontal rod perpendicularly connected with the vertical rod, wherein the vertical rod is fixed with a socket insertion seat. Obtrapezoid grooves are arranged on all circumferential sides of the surface of a connecting portion of the socket insertion seat; an obtrapezoid bump joint is arranged at the end of the horizontal rod connected with the vertical rod; and a nut is sleeved above the socket insertion seat of the vertical rod and used for being connected with the socket insertion seat in a threaded manner. The mechanism aims to hold down the obtrapezoid bump joint at the end of the horizontal rod by the aid of threaded connection of the nut with the upper end of the socket insertion seat on the vertical rod, simultaneously simplifies structure, improves assembly and disassembly efficiency, reduces cost, improves safety stability and increases reuse ratio.

Description

Scaffold bindiny mechanism

Technical field

The utility model relates to a kind of scaffold bindiny mechanism, relates in particular to the upright fourth of the twelve Earthly Branches of a kind of novel horizontal tenon socket joint scaffold bindiny mechanism that is threaded.

Background technology

Conventional fastener formula steel pipe scaffold structure is complicated, install and remove more loaded down with trivial details, repeat usage is low, the node steel using amount is big, the node accessory is lost easily, and caused vertical rod and being connected of other cross bar to be affected because of destroying part cross bar and being connected of vertical rod sometimes, lack convenience and security and stability.

Summary of the invention

For simplified structure, improve mounting or dismounting efficient, reduce cost, improve security and stability, increase repeat usage, the utility model provides a kind of scaffold bindiny mechanism, specifically is the upright fourth of the twelve Earthly Branches of a kind of novel horizontal tenon socket joint scaffold bindiny mechanism that is threaded.

The utility model comprise vertical rod with the vertical cross bar that is connected of vertical rod, it is characterized in that: described vertical rod is fixed with the socket joint socket, the all sides in described socket joint socket connection part surface are equipped with inverted trapezoidal groove, and its end of the cross bar that links to each other with vertical rod is provided with down trapezoidal projection joint; The socket joint socket top of vertical rod is arranged with nut, and described nut is used for being threaded with the socket joint socket.

Advantage of the present utility model is, and is simple in structure, resistance to overturning good, fast assembling and disassembling, easy to use; Because the node connection fittings are fixed on the rod member, avoiding losing of component and fitting aspect the keeping, the repeat usage height has reduced the cost of using.From the stress performance aspect,, improved its supporting capacity greatly because rod member all axially connects; Next is that the socket joint socket that bears the cross bar vertical force directly is packed in the vertical rod, the scaffold of the frictional force carrying vertical force when holding with a firm grip with main dependence fastener is compared, the rod member connection reliability is not subjected to artificial on-site construction operations factor affecting, and the stress performance of its " node " is improved.The connected node of this scaffold bindiny mechanism can connect four cross bars simultaneously, vertical rod is with after cross bar is connected, be threaded by the upper end of the socket joint socket in nut and the vertical rod and push down the trapezoidal projection joint of falling of crossbar end, the upright fourth of the twelve Earthly Branches of this horizontal tenon socket joint thread connecting mode can bear straight up or downward load, and can bear certain bending moment, punching and moment of torsion, make scaffold form space structures support with better stability, be suitable for setting up civil engineering structure construction and the dual-purpose external scaffolding of fitment operation, can also be that a kind of design is unique as bracing frame and other temporary platform supports of template, novel structure, wide adaptability, flexibility is strong, convenient and practical new type scaffold.

The specific embodiment

The utility model is an a kind of scaffold bindiny mechanism, comprise vertical rod 1 with the vertical cross bar that is connected 2 of vertical rod, be fixed with socket joint socket 3 in the described vertical rod 1, the all sides in described socket joint socket 3 connecting portions surface are equipped with inverted trapezoidal groove 4, and cross bar 2 its ends that link to each other with vertical rod 1 are provided with down trapezoidal projection joint 5; Socket joint socket 3 tops in the vertical rod 1 are arranged with nut 6, and described nut 6 is used for being threaded with socket joint socket 3.

For socket joint socket 3 is threaded with nut 6, realize that the lid of trapezoidal projection joint 5 of falling of 6 pairs of cross bar 2 ends of nut presses, escape when preventing that cross bar 2 from bearing straight up load, the top of the utility model socket joint socket 3 is provided with the external screw thread 7 that is connected with nut 6, and the lower inside of nut 6 is provided with the internal thread 8 that is connected with socket joint socket 3.

For cross bar 2 is connected with vertical rod 1, it is little that the trapezoidal projection joint 5 upper and lower surfaces outside 9 big inboard 10 is fallen in cross bar 2 ends, and the inverted trapezoidal groove 4 of geomery and described socket joint socket 3 is complementary.

When scaffold bindiny mechanism makes, just weld down trapezoidal projection joint 5 at cross bar 2 two ends of certain specification length, in vertical rod 1, install (can weld or be threaded) and have the socket joint socket 3 of inverted trapezoidal groove 4, cover top nut 6 above the socket joint socket 3 in the vertical rod 1 is convenient to accelerate the on-the-spot speed that connects.During on-the-spot the connection, earlier nut 6 is pulled upwardly (upwards sliding) along vertical rod, the trapezoidal projection joint 5 of falling of all directions cross bar 2 ends is aimed at the back to be inserted with the inverted trapezoidal groove 4 on the socket joint socket 3, subsequently nut 6 is slided along vertical rod 1, and be connected to push down the trapezoidal projection joint 5 of falling of cross bar 2 ends with socket joint socket 3 upper external thread 7, nut 6 outside projections 9 that pound with a hammer screw to whole screw threads and can reach the requirement that compresses down trapezoidal projection joint 5.Adopt this connected mode, cross bar 2 is threaded for the upright fourth of the twelve Earthly Branches of horizontal tenon socket joint with vertical rod 1, and cross bar 2 can not break away from vertical rod 1 under horizontal force action; Simultaneously, falling the shape of trapezoidal projection joint 5 and inverted trapezoidal groove 4 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 socket joint socket 3 upper external thread 7 by the nut in the vertical rod 16 and pushes down the trapezoidal projection joint 5 of falling of cross bar 2 ends, make cross bar can not come off.Connected node is to realize fixing cross bar 2 by the internal thread 8 that is located at nut 6 inboards with 7 interlocks of socket joint socket 3 upper external thread in the utility model.

The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
