Description
Technical field
The utility model is related to dampers, more particularly to a kind of frcition damper suitable for spatial mesh structure.
Background technology
With being continuously increased for China's iron and steel output, the application of long-span space steel latticed structures is more and more extensive.Greatly across sky
Between steel latticed structures include rack, reticulated shell and steel pipe truss structures etc., be widely used in stadiums, conference and exhibition center, traffic
In the public buildings such as hinge, industrial premises.As in flat plate framed structure, Double-level Reticulated Shell and steel pipe truss structures, steel member is only by axis
To pulling force or pressure, stress is simply clear and definite, and stress distribution is uniform, and the usage amount of material is greatly saved, reduces structure
Dead weight.
When long-span space steel latticed structures can cause by earthquake, disaster caused by a windstorm etc. the force modes of structure, force path and
Stress distribution changes, and leads to global failure or node failure, so as to which the normal use for influencing structure even collapses, prestige
Coerce people life property safety.In order to mitigate the vibratory response of structure, energy-consuming device can be arranged in structure.
In terms of passive energy dissipation, traditional tuned mass damper, viscosity are mainly set on large span spatial structure
Damper, general using replacement and the setting of additional two ways, the relevant technologies mainly use for reference the damping technology of general house structure,
Lack the combination for large span spatial structure characteristic.In addition, viscous damper is there is also some shortcomings, as processing and fabricating is more difficult,
Viscous liquid easy to leak.
Utility model content
The purpose of the utility model is to overcome deficiency of the prior art, provide it is a kind of safely and effectively, stability is good, construction
The simple damper for being suitable for spatial mesh structure.
Technical solution is used by the utility model：A kind of frcition damper suitable for spatial mesh structure, including
Outer steel pipe, interior steel pipe, tubular friction plate；There are two the outer steel pipe settings, is sheathed on the both sides of the interior steel pipe respectively, described
The long sliding slot slided for high-strength bolt is offered in outer steel pipe；The tubular friction plate is arranged on the outer steel pipe and the interior steel
Between pipe, high-strength bolt passes through the long sliding slot to connect the tubular friction plate and the interior steel pipe, makes outer steel pipe, tubular friction
It is close to frictional connection between piece and interior steel pipe, the tubular friction plate, the interior steel pipe and the high-strength bolt can be jointly along institutes
It states long sliding slot and opposite slide occurs with the outer steel pipe.
The outer steel pipe internal diameter is equal to the tubular friction plate outer diameter.
The tubular friction plate internal diameter is equal to the interior outer diameter of steel pipes.
There are four the long sliding slot settings, is distributed along the outer steel pipe even circumferential.
The high-strength bolt is set in the middle part of the long sliding slot.
The beneficial effects of the utility model are：
The utility model is mainly held suitable for the frcition damper of spatial mesh structure using rod piece spatial mesh structure
By axle power, stress is clear and definite, this uniform feature of stress distribution directly replaces the rod piece in spatial mesh structure, is not required to separately set attached
Add damper.High-strength bolt pretension provides pressing force between outer steel pipe and friction plate in the utility model frcition damper, just
Under normal working load and small shake effect, opposite slide, while can provide enough will not occur for outer steel pipe and tubular friction plate
Rigidity；Under big shake effect, outer steel pipe is slided with tubular friction plate along axis is opposite, and the force of sliding friction of generation can cause very greatly
Damping force, effectively dissipate seismic energy, achievees the purpose that vibration damping.The utility model frcition damper construction is succinct, installation
It is convenient, convenient disassembly, convenient for construction.Not only can be to avoid the earthquake danger that structure may be destroyed when excessive, but also have significant warp
Ji benefit.

Specific embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in attached drawing 1 to Fig. 3, a kind of frcition damper suitable for spatial mesh structure, including outer steel pipe 1, interior steel
Pipe 3, tubular friction plate 2；There are two the settings of outer steel pipe 1, is sheathed on the both sides of the interior steel pipe 3, the outer steel pipe 1 respectively
On offer the long sliding slot slided for high-strength bolt 4；The tubular friction plate 2 is arranged on the both sides of the interior steel pipe 3, and sets
Between the outer steel pipe 1 and the interior steel pipe 3,1 internal diameter of outer steel pipe is equal to 2 outer diameter of tubular friction plate, the cylinder
2 internal diameter of shape friction plate is equal to interior 3 outer diameter of steel pipe；High-strength bolt 4 passes through the long sliding slot to connect 2 He of tubular friction plate
