Description

Composite steel pipe scaffolding

The present invention relates to steel pipe scaffold, relate in particular to building and build by laying bricks or stones and use the console mode steel pipe scaffold.Existing building is built by laying bricks or stones with console mode steel pipe scaffold system, its main component mainly comprises rod member and fastener and pedestal etc., described rod member mainly comprises vertical rod, leger and little cross bar, system adopts the steel pipe manufacturing of unified diameter specifications, described fastener mainly contains the perpendicular type fastener, yi word pattern fastener and rotary type fastener etc., in addition except that must establishing the wall connecting rod, still need and install strut (diagonal brace or bridging), be used for strengthening the integral rigidity of scaffold, in addition also attached scaffold floor of this scaffold and stair device etc.Existing this type scaffold uses also more extensive at present, also has and for example sets up flexibly, and easy accessibility can be set up into higher advantages such as height, the also firm and safety of in general this scaffold.But the problem that this type steel pipe scaffold mainly exists is that to set up the artificial or amount of labour of scaffold institute spend big, thereby make the speed of application of setting up scaffold slow, can not adapt to current builing industry, especially develop the needs of high-rise building, secondly, this type scaffold desired structure material is more and loss is also bigger, and also there is the problem of fool proof inadequately aspect such as reliable in this in addition scaffold.These problems that exist in the above-mentioned scaffold mainly are that the rod member connected mode that adopts owing to this scaffold and the form of structure of scaffold member produce.The rod member of this class steel pipe scaffold adopts fastener to connect, this connected mode, refer in particular in the vertical rod and the so-called laterally tie point between the cross bar of scaffold, because it is many to carry out the rod member of this connection, and a fastener can only connect two rod members, form a contact, thereby the contact that forms on rod member is many, make the scaffold building operation task heavy, also be easy to generate mistake.Now in setting up, to use maximum perpendicular type fasteners to be example as laterally connecting, it is to contact with two external cylindrical surfaces that intersect rod members respectively by the inner cylinder face of two different directions on the fastener, and tighten by the bolt on the fastener and to realize connecting, because described fastener is generally the last moulding of casting, add that described contact is the face contact, therefore allowing to produce effective clamping force is restricted, the influence that tends to be set up operating personnel's skill or experience like this and be subjected to factors such as various natural climate conditions, make the junction of rod member loosening through generation long afterwards, therefore especially must the installing strut when setting up the scaffold of high height.In addition, because the fastener that this scaffold adopted is many, the rod member length that is adopted is long and kind is many, different in size, all brings many troubles for management and carrying.

The present invention overcomes the above problems in order to consider exactly, special proposition is a kind of can guarantee that structural safety is reliable, and can make set up simple to operate, improve erection construction efficient, and the system that can save the structure material material and reduce the loss of structural meterials and can make the combined steel pipe scaffold of management and member convenient in carrying.

Scaffold device of the present invention proposes a kind of tube connector mainly as the connection between vertical rod, a kind of Connection Block mainly is connected as between vertical rod and cross bar, described tube connector is to fix a projection respectively at two of a short tube, along the short tube longitudinal direction and pass described projection and establish a straight-through breach, and on described projection and along the short tube horizontal direction, be provided with tapped through hole respectively, limit a hole, garden that can allow vertical rod slide through on the short tube, described Connection Block is one to comprise the integrated member of a cross section major part II and a cross section smaller portions I, heart position limits a cylindrical hole that can allow vertical rod slide through therein, around it, limit four and pass the part II, and cylindrical hole that relative centered cylinder axially bored line is symmetrical or a plurality of little teeth of even formation on this cylindrical hole inner cylinder face, holes around these is axially arranged with a straight-through breach respectively, and establish a tapped through hole along two of the vertical direction of described breach respectively, also along one of described center cylindrical hole vertically establish straight-through breach, and establish a tapped through hole along the vertical direction of this breach, and the radial direction along the other end of described center cylindrical hole is established a tapped through hole, a kind of rod assembly, a kind of base assembly, a kind of cross bar assembly, described rod assembly is that an a kind of end at its vertical rod one end and a described tube connector is fixedly connected, the position is provided with the location apical pore at a certain distance therebetween, install and fix the combining structure member of a described Connection Block respectively at described apical pore place, described cross bar assembly is a kind of cross bar assembly or a kind of cross bar assembly with variable-length with regular length, and be provided with little axle respectively at the two ends of described cross bar assembly, the cross section that this little axle has garden shape or regular polygon shape, described base assembly is a kind of bedframe that comprises a fixedly connected adapter sleeve thereon, one regulates screw mandrel is fixed in the described adapter sleeve combined member that an end of a described tube connector and the nut of described adjusting screw mandrel install and fix.Scaffold proposed by the invention also must lay wall connecting rod, but can not establish strut, the also attached scaffold floor of described scaffold device, over brace, the stair device, promote equipment etc., adopt the blank of the steel pipe all identical with the material specification as this connection system for guide rail rod member with the diameter of existing scaffold use.

Because the present invention has used connected mode as described above, therefore no matter in the connection between the vertical rod or more solid and reliable in the connection between vertical rod and the cross bar with existing connection system for guide rail, this be since the connection of the connected mode that the present invention adopts in addition part make with connected piece between to contact can be the line contact, in addition, because what this connection system for guide rail adopted is elastic connection way, can contact other part to connection easily and apply enough elasticity clamping forces, thereby can guarantee to connect closely reliable and difficult loosening.Scaffold building of the present invention is easy for installation, the efficiency of construction height, and this is because all modularization and normalization of structural member of scaffold of the present invention, and all connectors all are installed together with connected piece in advance, makes on-the-spot easier for installation.Because the normalization and other part count of the structural member of scaffold of the present invention significantly reduce, and bring convenience to field supervision, can also save the structural steel tube material.Scaffold member manufacturing of the present invention is simple, and cost is low, implements easily.

Connection system for guide rail of the present invention can mainly be built by laying bricks or stones with the outer shelf of console mode as building, and the scaffold that is particularly suited for setting up high-rise scaffold or has various different facade shapes also can be used for steel form and is supported on indoor use, and saves construction timber.
