The connecting piece is simple and reasonable in structure, and easy for use and dismounting, and can effectively lowering a top cantilever, which ensures the stability of an entire supporting structure and safety of structure construction.
Description
Technical field
The utility model relates to the adjustable jacking of scaffold, more specifically relates to a kind of connector that can reduce the adjustable jacking cantilever height of scaffold.
Background technology
At present, aspects such as socket joint class bowl fastening type or slot wedge formula scaffold extensive use building construction, bridge construction, it is that (connecing) spigot-and-socket steel pipe scaffold is intersected in a kind of rod member axle center, have easy accessibility, efficient height, good integral strength, safe and reliable, safeguard characteristics such as simple, has stronger stable bearing capacity than fastener type steel pipe scaffold, not only can assemble various scaffold, and be more suitable for constructing supporting frame, particularly heavily loaded bracing frame.The length specification of its vertical rod is standardization, and 1.2m, 1.8m, four kinds of specifications of 2.4m, 3.0m are arranged, and when setting up support body, the jacking that rod end generally inserts adjustable supporting height bears the load that transmit on top, and the push rod of jacking is a screw rod.In the middle of the engineering construction, because restriction, the scaffold upright rod material of building floor height do not match, when vertical rod, jacking assembly appear in regular meeting; the cantilever height of jacking is excessive; particularly under heavily loaded situation, cause the stability of scaffold compression member not enough, directly influence structure construction safety.
Therefore need a kind of accessory that can be assembled on the jacking of design, can be connected in length and breadth, reduce the cantilever height of jacking, satisfy the stability of scaffold compression member with common steel tube, fastener.
Summary of the invention
The purpose of this utility model is to be to provide a kind of connector that can reduce scaffold jacking cantilever height, and it is simple in structure, and highly versatile can satisfy various supporting support bodys, and is particularly suitable to the supporting frame that adopts socket joint class bowl fastening type or slot wedge formula scaffold.
In order to realize above-mentioned purpose, the utility model adopts following technical scheme:
A kind of connector that can reduce scaffold jacking cantilever height is not change on the adjustable jacking structure of scaffold commonly used, increasing this connector.Adjustable jacking commonly used is made up of to use the adjusting nut that is assembled on the push rod push rod, bracket basically.Connector is characterised in that: connector is by upper locking nut, branch sleeve, lower locking nut, and the pivoting leaf that is welded on upper locking nut, lower locking nut sidewall is formed, upper locking nut, branch sleeve, lower locking nut are assembled on the push rod, branch sleeve and embeds in the groove of upper locking nut and lower locking nut between lower locking nut and upper locking nut.
Above-mentioned upper locking nut, branch sleeve, lower locking nut, adjusting nut are assembled on the push rod downwards at the bottom of bracket successively.
Branch sleeve adopts Φ 48mm common steel tube, and inwall is a tubular.Upper locking nut, lower locking nut are general, and upper locking nut, lower locking nut are " recessed " shape, and branch sleeve embeds in the groove of upper locking nut and lower locking nut.
A kind of connector using method that can reduce scaffold jacking cantilever height:
A, push rod is inserted in the vertical rod of scaffold top, the rotation adjusting nut satisfies the joist installation requirement until the position of bracket, and adjusting nut and vertical rod are locked.
B, elder generation's rotation lower locking nut embed branch sleeve in the lower locking nut groove, rotate upper locking nut again, fixedly connected sleeve.
C, be connected on the branch sleeve in length and breadth with common steel tube and fastener.
The utility model advantage is, and is rational in infrastructure, and simple structure is easy to use, and dismounting is simple, can reduce the jacking cantilever height effectively, thereby improves the stability of supporting frame, guarantees structure staged construction safety.
