Description
Technical field
The present invention relates to a kind of support body nodal connection device, particularly a kind of device for combined scaffold vertical rod, cross bar and cable-stayed support composite joint.
Background technology
Domestic for the support body node connector, the types of attachment such as fastener type, bowl fastening type, wedge spigot-and-socket are arranged, its function singleness, can only interconnect two rod members, and the joints complexity.Chinese patent ZL200920245978.9 discloses a kind of combined scaffold that can be for convenience detach and has connected with butterfly card assembly, the all rod members of support body node (vertical rod, cross bar and cable-stayed support) effectively can be connected, the modular combined scaffold rectangular element that it is formed by connecting, can make each center line of the bar junction on one point, the stressed rear formation concurrent force system of each rod member, make its scaffold system in the three-dimensional repeated combination become static determinacy or statically-indeterminate structure, the support body bearing capacity is high, and it is convenient that peace is torn open.But there is following problem in this butterfly card assembly: (1) complex structure, and weight is relatively large; (2) the connector power transmission is stressed unreasonable, and coupling assembling is subject to horizon bar horizontal force and diagonal member skew force, relies on the carrying of public card end shearing resistance Anti-bending structure, and degree of safety is poor; (3) when last item in freely becoming flexible under state, the coupling assembling Joint failure, can not realize self-locking between the male and female card.
Summary of the invention
For the existing weakness of background technology butterfly card assembly, the purpose of this invention is to provide a kind of linkage that male and female is linked connect the combined scaffold node of safety and reliability.
For reaching above purpose, the present invention takes following technical scheme to be achieved:
A kind of self-locking spherical hinge butterfly card assembly connected for the combined scaffold node, comprise a master card, four public cards and four wedge shape iron that four public cards are connected with the master card coupling, it is characterized in that, master card comprises four cylindrical body that the segment of symmetry surrounds in twos, internal diameter and the vertical rod of cylindrical body connect firmly, the cylindrical body periphery arranges the planche cross plate, with cylindrical body, surrounds criss-cross four installation cavitys, and each installation cavity connects a public card by a wedge shape iron; Described installation cavity inboard is protruding sphere, and the outside is arc convex; Described public card comprises " η " shape card, card upper surface near the short side of " η " shape has the square opening that can insert wedge shape iron, the short side of its " η " shape outside is the spill sphere be complementary with the inboard protruding sphere of installation cavity, the short side inner face of " η " shape has an inclined-plane and vertical plane to be angle [alpha], and this inclined-plane extends to the square opening of " η " shape upper surface always; The parallel butterfly wing before and after the long side of " η " shape upper and lower part arranges respectively, the top butterfly wing is mutually corresponding with the bottom butterfly wing, for connecting vertical diagonal member; Connect horizon bar between the butterfly wing of upper and lower part, the long side outer face of " η " shape; The described wedge shape iron short side of " η " shape relatively is simultaneously straight plane, and the middle part of the long side one side of " η " shape is provided with projection relatively, and wedge shape iron upper end to projection is up-small and down-big wedge shape, and inclined-plane and vertical plane that projection forms downwards have oblique angle β, α>β>0.
In such scheme, have four horizontal diagonal member connecting holes on described planche cross plate, with the symmetrical center line of criss-cross four installation cavitys, be 45 ° of layouts.The afterbody of described wedge shape iron goes out the straight plane of wedge shape iron to the short lateral deviation of " η " shape.Described α=6 °; β=4 °.Be provided with installing hole between the butterfly wing of upper and lower part, the long side outer face of described " η " shape card.
With existing butterfly card assembly, compare, the advantage of self-locking spherical hinge butterfly card assembly of the present invention is:
1, coupling assembling reasonable stress, the male and female cartoon is crossed in the connection chamber that wedge is connected to a sealing, and connection integrity is good, and the connector moment of flexure is little, and each assembly bearing distribution is reasonable.
2, self-locking makes coupling assembling be connected safety and reliability with the wedge angle configuration to utilize the spherical structure self-locking.When wedge may be in freely becoming flexible under state, the coupling assembling connection was not lost efficacy.
When 3, coupling assembling is in running order, under the wedge pressure-acting, by sphere frictional force, can realize connecting mechanical characteristic like stationary nodes.
4, the male and female card adopts the connection that cooperatively interacts of concavo-convex sphere, can regulate up and down because of support body processing, the site error caused is installed, and node connects without additional flexure stress
