Description
Technical field
The utility model belongs to construction engineering technical field, and in particular to a kind of rope brace-frame structure with fuse.
Background technique
Drag-line is a kind of light-weight high-strength material, is widely applied to cable-stayed bridge, suspension cable bridge, greatly across gymnasium, towering
In tower mast structure.
Though drag-line is applied to also more rare at present in high building project, existing patent and paper are disclosed and are reported
Drag-line support construction.For example ZL200910031942.5 discloses a kind of prestressed giant brace-frame structure, in traditional steel
Outside frame structure, setting across it is several layers of it is several across rope support.In recent years, drag-line is as anti-side element also at high-speed rail station etc.
It is tried out in architectural engineering.
Studies have shown that structure ductility can be declined, to influence rope branch after traditional steel frame setting prestressed cable supports
Support the application in the architectural engineering of earthquake protection area.The key of problem is that high-strength drag-line is generally a kind of brittle break material,
Sign is not obvious enough before destroying.And the unexpected fracture of drag-line, often will lead to the structural failure near drag-line again even influences
Integrally-built safety, the i.e. continuous collapse of academia's appellation.
Utility model content
The purpose of the utility model is to overcome problems of the existing technology, provide a kind of rope support-with fuse
Frame structure.
To realize above-mentioned technical purpose and the technique effect, the utility model is achieved through the following technical solutions:
A kind of rope brace-frame structure with fuse, the structure include the frame structure that Liang Yuzhu is connected to form,
It is equipped with the rope to cross one another two-by-two in the frame structure that the beam and column are formed to support, is in series with fuse in the rope support,
And the axial tensile-strength of the rope support is greater than fuse bearing capacity corresponding with the axial tension that rope supports.
Further, the fuse is that rope supporting base end portion is arranged in and supports the short beam structure intersected with rope, described short
The both ends of beam respectively with beam and the oblique connection of column.
Further, the fuse is to be connected on rope support middle part and the open column shape object with rope support coaxial line.
Further, the rope support and the concatenated mode of open column shape object are two breakpoints and open column shape of rope support
Object is directly connected to or two breakpoints of rope support are each passed through open column shape object and anchor to open column shape object respectively
Different ends form rope and are supported on the bridging arrangement in open column shape object.
Further, the material of the beam and column is steel, and the material of the rope support is round steel pull rod, steel strand wires or steel
Cord.
Further, it is connected between the rope support and short beam by an otic placode, is passed through between the short beam and beam and column
It is bolted.
Further, the short beam is steel I-beam.
Further, the open column shape object is round steel pipe.
The beneficial effects of the utility model are:
1. wringing support for height provides " fuse ".Support is efficient means, and horizontal loading is undertaken by it first, therefore
Under macroseism, hurricane effect, support also makes it easy to take the lead in destroying.Similarly, height, which is wrung, is supported under macroseism, hurricane effect, internal force
Meeting growth always is until destroy, and height wrings support different from conventional steel brace, high strength characteristics cause its destruction disconnected for moment
It splits, therefore personnel escape can be seriously affected.The utility model is that height wrings support provided with " fuse ", when rope internal force for support reaches
When to design threshold values, fuse just plays a role, and allows the no longer sustainable growth of rope internal force for support, takes the lead in brokenly so as to avoid drag-line
It is bad, also avoid " destroying suddenly ".
" 2. fuse " plays a role, rope, which supports, still " keeps hilllock load duty ".It is well known that the fuse in electrotechnics,
When electric current reaches threshold values, disconnects conveying its concatenated electric wire power failure, also just stop working.And the rope of the utility model
It supports " fuse ", when rope internal force for support reaches design threshold values, fuse, which does not disconnect instead of, leads to rope support failure, passes through
The deformation of fuse itself substantially increases, and then conveys its concatenated rope support unloading, but rope support and fuse are still string
The effective component being linked togather, remaining as structure carries the responsibility for resisting horizontal loading, be only the component that undertakes to the end,
It will not be further added by.
3. being easily changed.Traditional structure is under macroseism, hurricane effect, even the local damage of structure, often because
It is difficult to replace component and have to push over newly-built." fuse " simple structure of the utility model is all most common steel structure only
Part, all parts of the country are all available locally；" fuse " connects with rope support, and this mode for being connected in series through live bolt assembly is real
It is existing, it is bolted the replacement for greatly facilitating " fuse ".
