Description

A kind of steel tube scaffold linkage
Technical field
The utility model relates to technical field of building construction, is a kind of steel tube scaffold linkage.
Background technology
Scaffold refers to that engineering construction is on-the-spot for operative and the various supports solving vertical and horizontal transport and set up.According to the difference of used material, scaffold can be divided into bamboo scaffolding, timber scaffolding, steel pipe scaffold, synthetic materials scaffold, and current use is the most general, should belong to steel pipe scaffold.In steel pipe scaffold system, according to the difference of stress performance, door-type scaffold, total sub-semigroup, design of coupler scaffold and spigot-and-socket scaffold can be divided into again.As the interim load-carrying members in construction process, bearing capacity and the stability of what people paid close attention to most is steel pipe scaffold, set up the impact of parameter if do not consider, single from the viewpoint of steel pipe scaffold self, to its bearing capacity and stability influence maximum be its connected node rigidity.According to investigation, the connected node of steel pipe scaffold belongs to semi-rigid, its both non-fully just connect, also imperfect hinged, but between these two kinds of extreme cases, namely connect and there is limited rigidity.For the tolerance of Semi-rigid, countries in the world design specifications generally adopts moment-rotation relation as design considerations.At present, what China's use was maximum is fastener type steel pipe scaffold, and experimental study finds, its node coupling stiffness is relevant with screw-down torque to a great extent, considers the difference of manual operation, and its connection stiffness discreteness is comparatively large, and this is larger to the safety effects of scaffold.In addition, in fastener type steel pipe scaffold, cross bar is connected with vertical rod by fastener, and the load acted on cross bar is equivalent to wobbler action in vertical rod, and its second-order effects produced also can have a negative impact to the bearing capacity of scaffold and stability.The appearance of bowl fastening type, spigot-and-socket scaffold solves the eccentric force problem of design of coupler scaffold, but its vertical rod and cross bar need independent production, cannot share with current conventional scaffolding steel pipe, and it is comparatively single to set up parameter, its scope of application is narrower, therefore uses not general.
Utility model content
The purpose of this utility model is for above weak point, provides a kind of quick release and firmly connects, the steel tube scaffold linkage of stable working, carrying stability and safety.
The scheme that the utility model technical solution problem adopts is, a kind of steel tube scaffold linkage, comprise the nodal point connecting connecting cross bar and vertical rod, described nodal point connecting is polygon cube, the all sides of described nodal point connecting are provided with some threaded collar, described threaded collar inside is coaxially arranged with annular slot respectively, described nodal point connecting is vertically arranged with cylinder through hole, described nodal point connecting all sides threaded collar is coaxially connected with cross bar sleeve pipe respectively, described cross bar sleeve pipe end side is provided with the screw thread that can be connected with the threaded collar of nodal point connecting, the locating button be fixed in vertical rod is provided with below described nodal point connecting.
Further, described locating button is the two semicircular clevis sheet be inter-connected via a bolt joint.
Further, described nodal point connecting is eight limit cubes, and described nodal point connecting all sides threaded collar number is four.
Further, described nodal point connecting, cross bar sleeve pipe are made up of tube material.
Compared with prior art, the utility model has following beneficial effect: this steel tube scaffold linkage is provided with nodal point connecting, stable working, scaffold quick-detachment can be realized, and stress performance is good, connect in length and breadth to steel pipe by nodal point connecting, steel pipe axis is in same plane, there is not wobbler action time stressed; Connection stiffness is large, and cross bar is fixed by the annular slot in threaded collar in nodal point connecting and node, and utilizes cross bar sleeve pipe to retrain its rotational freedom further in periphery, substantially increases connection stiffness; Easy installation and removal, speed of application is fast, during installation, only need fix locating button with torque spanner in vertical rod, and remaining part all can manual installation, nodal point connecting is inserted in vertical rod, and installs cross bar sleeve pipe thereon, just can insert fixed transverse rod.During dismounting, screw out cross bar sleeve pipe, cross bar just can take out; Set up parameter various, applied widely.Because cross bar and vertical rod all need not independently be produced, can share with current conventional scaffolding steel pipe and use, and vertical pole ' s span and step pitch arbitrarily can change, and can meet the different needs of different engineering, both can use as external scaffolding, also can support or full hall scaffold as full hall; Production technology is simple, highly versatile.This means for fastening scaffolding only comprises three parts, nodal point connecting, cross bar sleeve pipe and locating button, and versatility is comparatively strong, arbitrarily can combine, meet the needs of different connecting portion.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
As shown in figures 1-4, a kind of steel tube scaffold linkage, comprise the nodal point connecting 1 connecting cross bar 5 and vertical rod 4, described nodal point connecting 1 is polygon cube, described nodal point connecting 1 week side is provided with some threaded collar 11, described threaded collar 11 inside is coaxially arranged with annular slot 12 respectively, described nodal point connecting 1 is vertically arranged with cylinder through hole 13, described nodal point connecting side threaded collar 11 was coaxially connected with cross bar sleeve pipe 2 respectively in 1 week, described cross bar sleeve pipe 2 end side is provided with the screw thread 21 that can be connected with the threaded collar 11 of nodal point connecting 1, the locating button 3 be fixed in vertical rod 4 is provided with below described nodal point connecting 1.
In the present embodiment, described locating button 3 is by bolt 32 interconnective two semicircular clevis sheet 31.
In the present embodiment, described nodal point connecting 1 is eight limit cubes, and described nodal point connecting 1 week side threaded collar 11 number is four.
In the present embodiment, described nodal point connecting 1, cross bar sleeve pipe 2 are made up of tube material.
Specific implementation process: mounting method is as follows: first determine scaffold building parameter, i.e. vertical rod 4 spacing and cross bar 5 step pitch, secondly locating button 3 be inserted in vertical rod 4 and use torque spanner screwed in place button 3, again nodal point connecting 1 is inserted in vertical rod 4 to fix, afterwards cross bar sleeve pipe 2 is screwed in the threaded collar 11 on nodal point connecting 1, finally cross bar 5 is inserted the annular slot 12 on nodal point connecting 1.Method for dismounting is as follows: first, screws out cross bar sleeve pipe 2 just desirable sheer pole 5, then takes out nodal point connecting 1, unload locating button 3.
Above-listed preferred embodiment; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
