Description
Technical field
This utility model relates to a kind of cable support node, particularly to a kind of prestressed steel structure cable support node.
Background technology
Suspen-shell structure and cable dome structure are widely used in gymnasium as a kind of NEW TYPE OF COMPOSITE spatial and prestressed structure, win
The public places such as thing shop, music hall.The feature of suspended-dome structure is that load passes to lower end by the single-layer lattice shell of upper end
On strut, then pass to rope by strut, after Suo Shouli, produce the deboost to bearing, make total to lower end about
The lateral thrust of beam ring beam is greatly reduced, and improves structure tension performance.
Current existing cable support node, is mostly unitary structure, and cross section is that the clamp of arc is built in arc-shaped cavity body,
During installation, first adjust drag-line position and flexibility so that it is fill in cavity by drag-line again after close with the radian of arc-shaped cavity,
Finally strain at rope with the bolt card of bottom arc clamp or side.This joint structure is feasible in theory, but is drawing
During rope practice of construction, owing to the very difficult manpower of drag-line or instrument are adjusted to be suitable for the radian of cord clip cavity, especially for
Reaching the drag-line of certain radian or certain diameter, its relative rigidity is the biggest in a length the least, and this results in
Drag-line cannot load in cord clip cavity.If by force drag-line being filled in, being on the one hand extruding drag-line, causing drag-line part steel
Silk or steel strand wires deformation, be on the other hand to cause the frictional force between prestressed cable and node inwall excessive.
In sum, existing cable support node structure can not meet the demand that construction drag-line is quick and easy for installation well, and deposits
In bigger loss of prestress.
Summary of the invention
This utility model provides a kind of prestressed steel structure cable support node for solving technical problem present in known technology,
This node, can be with the comfort level improving drag-line construction of high degree while meeting structure stress requirement, and reduction is executed
Work cost, and effectively reduce the frictional force of cable body and node cavity inner wall, also can preferably reduce in stretching process pre-simultaneously
The loss of stress.
This utility model is adopted the technical scheme that by solving technical problem present in known technology: one prestress steel
Structure cable support node, including cord clip under cord clip on a strop and a strop, on described strop under cord clip and described strop
Cord clip is bolted together by fixing, is provided with radial cable bar and connects otic placode, in described footpath on described strop on cord clip
Connecting otic placode to rope bar and be provided with bolt hole, on described strop, the bottom of cord clip is provided with cavity, at the top of described cavity
Being provided with strop upper fastening groove, the outer side surface of described cavity is plane, and medial surface is cambered surface；Under described strop, cord clip is upper
Portion is provided with the clamp coincideing with described cavity, under the top of described clamp is provided with the strop relative with described strop upper fastening groove
Clip slot, the lateral surface of described clamp is plane, and medial surface is cambered surface.
This utility model has the advantage that with good effect: by by rope under the outer side surface of cord clip cavity on strop and strop
The lateral surface of mounting board plate is set to plane, reduces the installation difficulty of prestressed cable, is effectively improved site operation effect
Rate, decreases prestressed friction loss, preferably achieves prestressed transmission.And this utility model beautiful design,
Reasonable stress, simple structure, can realize plant produced, assembled in situ, reduce construction technology difficulty, reduce construction cost；
Minor radius, thick cable body suspen-shell structure and the Fast Installation of Cable dome drag-line can be realized.

Detailed description of the invention
For summary of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate
Accompanying drawing describes in detail as follows:
Referring to Fig. 1～Fig. 6, a kind of prestressed steel structure cable support node, including cord clip 2 on a strop and a strop
Lower cord clip 3, on described strop, under cord clip 2 and described strop, cord clip 3 is linked together by fixing bolt 5, at described ring
On rope, cord clip 2 is provided with radial cable bar connection otic placode 4, connects at described radial cable bar and is provided with bolt hole on otic placode 4, in institute
State the bottom of cord clip 2 on strop and be provided with cavity 2-1, be provided with strop upper fastening groove 2-2 at the top of described cavity 2-1, described
The outer side surface of cavity 2-1 is plane, and medial surface is cambered surface；Under described strop, the top of cord clip 3 is provided with and described sky
The clamp 3-1 that chamber coincide, is provided with at the top of described clamp 3-1 and described strop lower fastening groove relative for strop upper fastening groove 2-2
3-2, the lateral surface of described clamp 3-1 is plane, and medial surface is cambered surface.
During use, strut 1 is welded on cord clip 2 top on strop, and strop is by clamping rope under cord clip 2 and strop on strop
Between folder 3, radial cable bar is connected to radial cable bar and connects on the bolt hole of otic placode 4.
Although preferred embodiment of the present utility model being described above in conjunction with accompanying drawing, but this utility model not office
