Description
Technical field
The present invention designs a kind of assembling type steel structure H profile steel Self-resetting energy dissipation brace device, belongs to Structural Engineering technology neck
Domain.
Background technique
Earthquake causes great threat as one of natural calamity, to the survival and development of the mankind, and causes greatly
Economic loss.It is western that China is located at Pacific Rim volcanic earthquake band, is earthquake disaster one of the countries with the most serious ... in the world, institute
Quake evaluation with building structure is an important job.The method for resisting earthquake is developed at this stage by initial antidetonation
Damping.Frame-Bracing Systems are one of common dual lateral resisting structure systems, and support construction can undertake major part
Horizontal shear reduces integrally-built horizontal displacement.Under geological process buckling easily occurs for traditional central support structure, causes
Brittle fracture influences integrally-built bearing capacity；Traditional eccentrically braces structure system, energy consumption beam-ends plastic deformation is larger, shake
After be difficult to repair；It is anti-buckling be supported on big shake effect after residual deformation it is larger, corresponding overall structure residual deformation is also larger, shake
After be difficult to repair.For these deficiencies, people have also been proposed self reset curvature-prevention support, and under geological process, Self-resetting is anti-to be bent
Song, which supports, can provide the anti-side rigidity of structure and the seismic energy that dissipates, and after geological process, be supported on the work of Self-resetting mechanism
It is returned to original state under, and then reduces the residual deformation of total.But after shake, support energy consumption kernel is destroyed
When, whole support is needed replacing, can not achieve and only replace the purpose that support is repaired by the kernel mechanism that energy consumption acts on, not only apply
Work is inconvenient, and wastes steel, and rehabilitation cost is also higher, and the arrangement supported influences the arrangement of door and window.And rope support construction
The deformation of middle rope is too big, and Suo Li increment is big, and structure cannot generate enough horizontal displacements to meet earthquake resistant code to ductility construction
Requirement.
Summary of the invention
The invention proposes a kind of assembling type steel structure H profile steel Self-resetting energy dissipation braces for belonging to technical field of structural engineering
Device makes structure under geological process its object is to overcome the deficiencies of existing technologies, and amplifies support bottom by leverage
The deformation of cable wire makes capital can produce enough horizontal displacements for meeting shockproof requirements.Bracing members are as energy consumption and Self-resetting system
System, can reduce or main structure is avoided to damage, and dissipation seismic energy and reduction geological process minimize structure residual deformation,
Rehabilitation expense and its indirect economic loss after shaking are reduced, the advantage of steel construction is embodied.

Influence the setting of frame space door and window.
Pin shaft is fixed on pedestal in the center of steel plate I, steel plate II, steel plate II, enables during steel plate I with pin shaft is
Heart rotation, forms lever mechanism, and brass sheet is attached on steel plate I；In column capital horizontal displacement effect lower pillar stand rotation, pass through
Leverage centered on pin shaft makes the rotation of steel plate I, to be rubbed by brass sheet with steel plate II to consume energy；
Cable wire passes through the preset hole in column lower part, and is fixed with anchorage, and end passes through pullover and applied by anchorage pre-
Clamp force fixes it and is adjustable the rigidity of structure；Under the horizontal force action of column capital, dissipative system rotation, the pullover of two sides
It is extruded and is deflected outward, extend cable wire, steel cable stretching force increases, and after horizontal force disappears, steel cable stretching force is as elastic restoring force
Dissipative system is set to be restored to original position, to make structure that there is runback bit function.
The bottom cable wire deformation of the support device is amplified by lever principle, makes to generate enough horizontal displacements at the top of column
To meet requirement of the earthquake resistant code to ductility construction maximum story drift, and amplification factor is by adjusting bearing height and cable wire
Position is realized.
Consumptive material can be reduced using H profile steel, avoids the wasting of resources.
Beneficial effect
Conventional frame-Bracing Systems drag-line support construction, when by capital horizontal force action, due to rope
Deformation is big, and corresponding Suo Li increment is big, prevent system is from generating enough relative storey displacements for meeting shockproof requirements；And it is of the invention
The bottom cable wire of support deform very little, lever principle amplifies this deformation, makes to can produce enough horizontal displacements at the top of column
To meet requirement of the earthquake resistant code to ductility construction maximum story drift, and amplification factor can adjust branch according to actual needs
Support height is realized with cable wire position；Under the horizontal force action of capital, dissipative system rotation, the pullover of two sides be extruded and to
Extrinsic deflection extends cable wire, and steel cable stretching force increases, and after horizontal force disappears, steel cable stretching force makes dissipative system as elastic restoring force
It is restored to original position, to make structure that there is runback bit function, to reduce the residual deformation of structure, there is structure certainly
Reset function；The friction of latten(-tin) and steel plate is consumed energy when structure is rotated by dissipative system.Compared to traditional inclined support structure, originally
Invention is rising structure and is H profile steel support, does not influence the setting of door and window and consumptive material is few.After earthquake, the spiral shell of dissipative system
Bolt is easily changed when destroying to carry out the reparation of structure, and vertical supporting is easy for installation, reduces the workload of site operation,
A large amount of manpower and material resources have been saved, the construction period is reduced.
