Description
Technical field
The present invention relates to a kind of drag-line node reinforced for space structure string.
Background technology
Since 1960s, grid structure has gradually developed in China, and current part engineering is due to
Reach that its service life, construction quality or load become to reinforce with greater need for structure.The reinforcement means of conventional rack has fibre
Tie up method for strengthening, reinforcement by sticking of sheets, casing reinforcement method and prestressing etc..Wherein prestressing by increase drag-line and
Original grid structure is changed into beam-string structure system by strut, can effectively reduce the deformation of structure, improves the rigidity of structure.
Strengthening construction need not be unloaded to existing structure simultaneously, and the rod member quantity that need to be reinforced also significantly reduces, and be a kind of efficient
Reinforcement means.
Drag-line need to be anchored in support node, and prestressing force is delivered on bearing.Drag-line node can be used in beam-string structure
Otic placode wears the modes such as ball, still, and the bearing of existing rack often connects remaining space on more, larger rod member, spheroid
It is smaller, larger difficulty is brought to the construction of drag-line and the connecting node of bearing；Meanwhile, according to traditional joint structure side
Method, needs to unload structure, the workload of reinforcing engineering is larger when welding structure.
The content of the invention
In view of the above-mentioned problems, drag-line is constructed with support node when the present invention is solves to use prestressed reinforcement to existing structure
Difficult the problem of, can reduce Site Welding workload, easy to operate is used for the drawing that space structure string is reinforced there is provided a kind of
Socket point.The present invention realizes the connection of drag-line and support node by steel wire rope, it is not necessary to other companies are welded at support node
Suo Li can be uniformly distributed in solder sphere sphere by connection device, steel wire rope, so that support node can also be without reinforcing.The present invention
Technical scheme it is as follows：
A kind of drag-line node reinforced for space structure string, realizes in existing structure welded spherical node 5 and reinforces, it is special
Levy and be, including steel wire rope 1, drag-line 2, dual-lug type rope first 3, bearing pin 4 and spacing steel pipe 6, bearing pin 4 is through dual-lug type rope first 3
Earhole, steel wire rope bypasses two ends after welded spherical node 5 and is placed on bearing pin 4, and spacing steel pipe is fixed on welded spherical node 5, plays limit
The effect that steel wire rope processed is slided along spheroid.
The steel wire rope can be using single rope, and its two limb makes a concerted effort to overlap with drag-line centerline direction, and steel wire rope and weldering
The intersection of node of receiving should be a bus of spheroid；Can also be using many ropes, each limb of steel wire rope is made a concerted effort need to be with drag-line center line
Direction is overlapped.The centre of sphere that the center line extended line of the drag-line passes through welded spherical node.
The present invention has advantages below compared with prior art：
(1) welding hollowing ball is attached with drag-line by steel wire rope, simple structure, execute-in-place is easy.
(2) need to carry out welding hollowing ball post-production is less, reduce Site Welding workload.
(3) Suo Li can be uniformly distributed in solder sphere sphere by steel wire rope, so that support node can also be without reinforcing.

Embodiment
The present invention will be described with reference to the accompanying drawings and examples.
The present invention proposes a kind of anchor-hold node of prestressed reinforcement, including steel wire rope 1, drag-line 2, dual-lug type rope head
3rd, bearing pin 4, existing structure welded spherical node 5 and spacing steel pipe 6.Steel wire rope bypasses two ends after welded spherical node 5 and is placed on bearing pin 4
On, bearing pin 4 passes through the earhole of dual-lug type rope first 3.
The steel wire rope can use wall scroll or a plurality of.When using single rope, its two limb is made a concerted effort need to be with drag-line centerline direction
Overlap, and the intersection of steel wire rope and ball node should be a bus of spheroid.When using a plurality of steel wire rope, each limb of steel wire rope is closed
Power need to be overlapped with drag-line centerline direction.
The drag-line can be using building structure drag-lines such as steel strand wires, half parallel wire unit or high vanadium ropes.Drag-line center
The centre of sphere that line extended line passes through ball node.
The dual-lug type rope head is generally a part for drag-line product, and HiAm anchorage or hot casting anchor are used by drag-line manufacturer
It is connected etc. mode with cable body.
The existing structure welded spherical node is the node that original roof structure joins with supporting structure.
The spacing steel pipe plays limitation steel wire rope and slided along spheroid, and its section is cut according to steel wire rope along spherome surface
Determined to component.
Include ring steel wire rope 1, drag-line 2, dual-lug type rope first 3, bearing pin 4, existing structure welded spherical node as shown in Figure 1, 2, 3
5 and spacing steel pipe 6.The axis direction of drag-line 2 bypasses welding ball-joint by the centre of sphere of existing structure welded spherical node 5, rope belt
The eye at two ends is placed on bearing pin 4 after point 5, and the axis direction of steel wire rope is using drag-line axis as symmetrical axial symmetry up and down.Bearing pin 4 is worn
The earhole of dual-lug type rope first 3 is crossed, spacing steel pipe is located at the both sides up and down of steel wire rope.
