Description
Art
The present invention relates to scaffold field, be especially the scaffold node of a kind of improvement, can be used for the overlap joint of scaffold in construction.
Background technology
Scaffold refers to the various supports that job site provides operating platform solution vertically and horizontally to transport and set up for workman.At present, common foot
Hand cradle has fastener type steel pipe scaffold, bowl fastening type steel pipe scaffold, Bayenet type steel tube scaffold, door-type scaffold etc..Wherein, fastener type steel pipe
Scaffold is most commonly seen, but it occurs problems with in application process:
(1) traditional design of coupler scaffold is to be connected with vertical rod by horizon bar by two fasteners on a node, by fastener power transmission, but
The antiskid rigidity and the bending rigidity that are fastener are more weak, greatly reduce the bearing capacity of design of coupler scaffold；
(2) conventional fastener formula steel pipe scaffold direction stress horizon bar in length and breadth generally arranges one, owing to scaffolding steel pipe specification is fixed, and stress
The bending strength of horizon bar is not enough so that fastener type steel pipe scaffold is dfficult to apply to case of heavy load；
(3), sometimes for the bending strength of raising top layer stress horizon bar, when needing a montant to be connected with many stress horizontal bars, just need
Wanting multiple fasteners, its connecting structure is complicated, connects weak effect, causes unidirectional stress horizontal bars not at same level height so that behaviour
Make the load on platform and can not pass to horizontal bars uniformly, reduce scaffold vertical rigidity, have impact on construction precision and working security.
Summary of the invention
Invention broadly provides a kind of antiskid rigidity higher with bending rigidity, can by a montant with many horizontal bars be connected and can Fast Installation,
Simple in construction, monoblock type scaffold node easy to use, be mainly used in scaffold top layer bearing area.
The technical scheme of patent of the present invention is:
A kind of monoblock type scaffold node, for horizontal bars being connected to the montant of scaffold, including sleeve and two fastener nodes, described
Horizontal bars include transverse horizontal rod member and vertical equity rod member, it is characterised in that
Sleeve diameter matches with scaffold montant external diameter, to ensure that sleeve can be enclosed within scaffold montant；Each solid in the upper and lower parts of sleeve
A fixed fastener node comprising two fasteners, a fastener node is in order to connect transverse horizontal rod member, and another fastener node is in order to connect longitudinal direction
Horizontal bars；
Each fastener includes fixed block, big clasp, little clasp, latch fitting, chain, chock and snap close, and fixed block is fixing with sleeve to be connected, and detains greatly
Ring is connected with fixed block by bearing pin respectively with little clasp, and the internal diameter after being connected matches with the external diameter of horizontal bars；The free end of big clasp is fixed
Having latch fitting, latch fitting is connected with chain by an axle, and chain is connected with chock by the axle on chock；Free end at little clasp is fixed with snap close,
Chock is in order to be buckled on snap close；
Two fasteners of the fastener node being arranged on the upper bit of sleeve are upwards buckled, be arranged on the lower node of the lower portion of sleeve fastener node two
Individual fastener is detained downwards.
Preferably, described monoblock type scaffold node, remaining silent in sleeve top, makes sleeve be fixed with montant；Chock is three
Dihedral, matches with chain, after being buckled on snap close so that the diameter that big clasp, little clasp and chain surround jointly and need water to be mounted
The diameter compatible of flat rod member closes；Described fixed block is made up of cast iron or cast steel.
Using the scaffold node of the present invention, when montant is connected with horizontal bars, transverse horizontal rod member is fixed on node, can set up work
Make platform, and make transverse horizontal rod member on sustained height so that upper load can be evenly distributed on two rod members.Vertical equity rod member is solid
It is scheduled on lower node, to ensure the monolithic stability of scaffold.Two transverse horizontal rod members and two vertical equity rod members are distributed in the both sides of sleeve,
Montant axial compression can be made, prevent its eccentric compression, improve ultimate bearing capacity.When fastener clasps horizontal bars, chock is buckled on snap close,
Owing to chock is triangle, can be by matching with chain so that diameter that big clasp, little clasp and chain surround jointly with installed
The diameter of horizontal bars is the same, by hammering chock 15 stub end, i.e. horizontal bars can be pinned, reach the purpose of Fast Installation.Vertical lotus
Carry and transmitted by the weld seam between attachment fastener and sleeve, greatly improve the antiskid rigidity of structure, provide the bending rigidity of node simultaneously.Always
It, when the present invention solves that in design of coupler scaffold, plurality of rods part is connected, the problems such as fastener is many, structure is complicated, bearing capacity is weak.

Detailed description of the invention
The present invention will be described with embodiment below in conjunction with the accompanying drawings
In FIG, monoblock type scaffold node includes sleeve 2, upper node 3, lower node 4.Wherein, sleeve 2 internal diameter is than scaffold montant 1
External diameter is slightly bigger, and to ensure that sleeve can be enclosed within scaffold montant, remaining silent in sleeve top, makes sleeve be fixed with montant.On sleeve 2,
Lower portion respectively welds a fastener node: go up node 3 and lower node 4.Upper node 3 includes foundry goods 12 and two fasteners 5 and 6, in order to connect
Transverse horizontal rod member 17.Lower node 4 includes foundry goods 12 and two fasteners 7 and 8, in order to connect vertical equity rod member 18.Foundry goods 12 and sleeve
2 welding.In order in constructing, scaffold is easy for installation, the fastener 5,6 of upper node 3 is for upwards to detain, and the fastener 7,8 of lower node 4 is to detain downwards.
The structure of each fastener is identical, the direction that except for the difference that fastener clasps.
As in figure 2 it is shown, each fastener includes big clasp 9, little clasp 10, latch fitting 13, chain 14, chock 15, snap close 16.Wherein, greatly
Clasp 9 is connected with foundry goods 12 by bearing pin with little clasp 10, therefore can rotate, and its radius is suitable with horizontal bars.Big clasp 9 free end
Upper welding latch fitting 13, latch fitting 13 is connected with chain 14 by an axle.Chain 14 is connected with chock by the axle on chock 15.Little clasp 10
Free end welding snap close 16.
During as it is shown on figure 3, montant is connected with horizontal bars, transverse horizontal rod member 17 is fixed on node 3, can set up work platforms,
And making transverse horizontal rod member on sustained height so that upper load can be evenly distributed on two rod members.Vertical equity rod member 18 is fixed on down
On node 4, to ensure the monolithic stability of scaffold.Two transverse horizontal rod members 17 and two vertical equity rod members 18 are distributed in the two of sleeve 2
Limit, can make montant 1 axial compression, prevent its eccentric compression, improve ultimate bearing capacity.
As shown in Figure 4, when fastener clasps horizontal bars, chock 15 is buckled on snap close 16, owing to chock is right angled triangle, can by with
Chain 14 matches so that the diameter that big clasp 9, little clasp 10 and chain 14 surround jointly as the diameter of the horizontal bars installed,
By hammering chock 15 stub end, i.e. horizontal bars can be pinned, reach the purpose of Fast Installation.
