Description
Art
The present invention relates to scaffold field, be especially a kind of scaffold node of improvement, can be used for the overlap joint of scaffold in building operations.
Background technology
Scaffold refers to that job site provides operating platform and the various supports solving vertical and horizontal transport and set up for workman.At present, common scaffold 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 the most common, but it occurs following problem in application process:
(1) traditional design of coupler scaffold is connected with vertical rod by horizon bar by two fasteners on a node, by fastener power transmission, but the antiskid rigidity of fastener and bending rigidity more weak, greatly reduce the bearing capacity of design of coupler scaffold;
(2) conventional fastener formula steel pipe scaffold in length and breadth the stressed horizon bar in direction usually arrange one, because scaffolding steel pipe specification is fixed, the flexural strength of stressed horizon bar is not enough, makes fastener type steel pipe scaffold be difficult to be applied to case of heavy load;
(3) sometimes in order to improve the flexural strength of the stressed horizon bar of top layer, when needing a montant to be connected with many stressed horizontal bars, just need multiple fastener, its connecting structure is complicated, connect weak effect, cause unidirectional stressed horizontal bars not at same level height, make the load on operating platform 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, a montant can be connected with many horizontal bars and can Fast Installation, structure monolithic scaffold node simple, 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 monolithic scaffold node, for horizontal bars being connected to the montant of scaffold, comprise sleeve and two fastener nodes, described horizontal bars comprises transverse horizontal rod member and vertical equity rod member, it is characterized in that,
Sleeve diameter matches with scaffold montant external diameter, to ensure that sleeve can be enclosed within scaffold montant; Respectively in the upper and lower parts of sleeve fix the fastener node that comprises two fasteners, a fastener node is in order to connect transverse horizontal rod member, and another fastener node is in order to connect vertical equity rod member;
Each fastener comprises fixed block, large clasp, little clasp, latch fitting, chain, chock and snap close, and fixed block is fixedly connected with sleeve, and large clasp is connected with fixed block respectively by bearing pin with little clasp, and the internal diameter after being connected matches with the external diameter of horizontal bars; The free end of large clasp is fixed with latch fitting, and latch fitting is connected with chain by an axle, and chain is connected with chock by the axle on chock; Be fixed with snap close at the free end of little clasp, chock is in order to be buckled on snap close;
Two fasteners being arranged on the fastener node at the upper position of sleeve are upwards buckled, and two fasteners being arranged on the fastener node of the lower node of the lower portion of sleeve are buckled downwards.
Preferably, described monolithic scaffold node, remain silent in sleeve top, sleeve and montant are fixed; Chock is triangle, matches with chain, is being buckled in after on snap close, and the diameter that large clasp, little clasp and chain are surrounded jointly closes with needing the diameter compatible of the horizontal bars of installing; Described fixed block is made up of cast iron or cast steel.
Adopt scaffold node of the present invention, when montant is connected with horizontal bars, transverse horizontal rod member is fixed on node, can set up working platform, and makes transverse horizontal rod member on sustained height, and upper load can be evenly distributed on two rod members.Vertical equity rod member is fixed 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, can make montant axial compression, prevent its eccentric compression, improve ultimate bearing capacity.When fastener fastens horizontal bars, chock is buckled on snap close, because chock is triangle, can by matching with chain, the diameter that large clasp, little clasp and chain are surrounded jointly is the same with the diameter of installed horizontal bars, by hammering chock 15 stub end, namely horizontal bars can be pinned, reach the object of Fast Installation.Vertical load, by the weld seam transmission between attachment fastener and sleeve, greatly improves the antiskid rigidity of structure, provides the bending rigidity of node simultaneously.In a word, when the invention solves that in design of coupler scaffold, many rod members are connected, the problems such as fastener is many, complex structure, supporting capacity are weak.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be described
In FIG, monolithic scaffold node comprises sleeve 2, upper node 3, lower node 4.Wherein, sleeve 2 internal diameter is more slightly bigger than scaffold montant 1 external diameter, and to ensure that sleeve can be enclosed within scaffold montant, remain silent in sleeve top, sleeve and montant are fixed.A fastener node is respectively welded in sleeve 2 upper and lower parts: upper node 3 and lower node 4.Upper node 3 comprises foundry goods 12 and two fasteners 5 and 6, in order to connect transverse horizontal rod member 17.Lower node 4 comprises foundry goods 12 and two fasteners 7 and 8, in order to connect vertical equity rod member 18.Foundry goods 12 welds with sleeve 2.In order to scaffold in constructing 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 button downwards.The structure of each fastener is identical, unlike the direction that fastener fastens.
As shown in Figure 2, each fastener comprises large clasp 9, little clasp 10, latch fitting 13, chain 14, chock 15, snap close 16.Wherein, large 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.Large clasp 9 free end welds latch fitting 13, and 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.
As shown in Figure 3, when montant is connected with horizontal bars, transverse horizontal rod member 17 is fixed on node 3, can set up working platform, and makes transverse horizontal rod member on sustained height, and upper load can be evenly distributed on two rod members.Vertical equity rod member 18 is fixed on lower 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 both sides of sleeve 2, can make montant 1 axial compression, prevent its eccentric compression, improve ultimate bearing capacity.
As shown in Figure 4, when fastener fastens horizontal bars, chock 15 is buckled on snap close 16, because chock is right-angled triangle, can by matching with chain 14, the diameter that large clasp 9, little clasp 10 and chain 14 are surrounded jointly is the same with the diameter of installed horizontal bars, by hammering chock 15 stub end, namely horizontal bars can be pinned, reach the object of Fast Installation.
