Abstract
The invention relates to an assembled steel structure self-restoration module based on support energy dissipation. The assembled steel structure self-restoration module comprises vertical edge components, transverse edge components, supporters and hinging posts, wherein a plurality of back tensioning prestress steel stranded wires are arranged along the two transverse edge components and are anchored on the outer side flanges of the two vertical edge components, so that a prestress framework is formed; the inner sides of the two vertical edge components are provided with the two hinging posts, and end plates are arranged at two ends of the two vertical edge components and are connected with the flanges of the two transverse edge components (the upper transverse edge component and the lower transverse edge component) through high-strength screw bolts; and the two supporters are connected with lug plates of the hinging posts through high-strength screw bolts to form an X-shaped crossed supporter. After the assembled steel structure self-restoration module is used, the structure can restore through the prestress steel stranded wires after great earthquake; only the supporters need to be replaced; and the operation is simpler and more convenient, so that the goals that the structure can restore to the original position without residual deformation after plastic deformation due to the earthquake, the maintenance time is shortened, the maintenance cost is reduced, and the structure can come into use as soon as possible are achieved.
Description
Technical field
The invention belongs to earthquake-proof construction technical field, relate to the structure based on support energy consumption.
Background technology
The Seismic Philosophy of China's present stage is " no damage in small earthquake; middle shake can be repaiied; no collapsing with strong earthquake ", after this Seismic Philosophy claimed structure meets with the earthquake of fortification intensity, agent structure does not have large destruction can repairing, meeting with after rarely occurred earthquake allows structure to have large destruction, but can not collapse and cause casualties.Even if but structure is not collapsed after suffering earthquake, but part important component has created larger permanent set and cannot return to original position, causes structure to be difficult to maintenance and reinforcement and is even pushed over reconstruction.
In order to realize structure after experience earthquake development plasticity, still can return to original position and there is no permanent set, thus shorten maintenance time, reduce maintenance cost and the target that comes into operation as early as possible, need to propose a kind of certain part that the plastic strain of structure can be controlled to be easy to change, afterwards by the module that prestress wire makes structure reset, and by its reasonable Arrangement in structural system.
Summary of the invention
The object of the present invention is to provide and a kind ofly the plastic strain of structure can be controlled at the support section being easy to change, afterwards by the assembling type steel structure Self-resetting module based on support energy consumption that prestress wire makes structure reset.

Further, described its end of vertical edges component arranges transverse stiffener.
Described its end of transverse edge component arranges transverse stiffener, end plate and cover plate.
The specification of described support steel, wood property and area are determined according to following requirement: make the plastic strain of Self-resetting module occur in support section by support energy consumption when guaranteeing that large shake occurs.
The end plate of described transverse edge component and the stiffener surface, the edge of a wing, inner side of vertical edges component are provided with frictional contact surface, and described frictional contact surface is formed through processing modes such as sandblastings, the anti-slip coefficient of its rubbing surface: for Q345 steel, must >=0.4.
The described support employing six prism sleeve gaily decorated basket-band steel column braces.
The six prism sleeves that the tensioning portion of described support adopts machining shaping, guarantee that the surrender bearing capacity of screw rod end is higher than at least 1.1 times of screw rod tensile bearing capacity design load;
Further, supporting member position adopts band steel, and the sectional area of described band steel is less than the minimum area of tensioning position screw rod, guarantees that described screw rod tensile bearing capacity design load is higher than at least 1.5 times of band steel tensile bearing capacity design load.
Described six prism sleeve materials are S5C, and described screw rod adopts Q345 round steel, and end is processed as M33 specification screw thread; Design of Screw Thread effective length is more than 40mm;
Further, described band steel material is Q235B, and described band steel adopts fillet weld to be connected between the two with described tensioning position screw rod, and support and connection plate is provided with bolt hole, is directly connected by support and connection plate with high-strength bolt with hinged styletable otic placode.
Described high-strength bolt is high strength bolt; Further, strength grade is 10.9s; Further, specification is M16 ~ M30.
The pretension of described post-stress steel strand is determined according to following requirement: 30%-50% of prestress wire ultimate bearing capacity, and selects suitable ground tackle anchoring.
Owing to adopting technique scheme, the present invention has following beneficial effect:
The connection of all components all adopts high strength bolt to connect, and simplifies construction technology, saves construction cost; Same element type cross-sectional shape size is no more than 3 kinds, and limiting member kind, improves industrialization degree, and integration degree is high; Agent structure bean column node is hinged, thus simplifies method for designing; Arrange the Self-resetting module containing supporting in agent structure, horizontal force major part is born (prestressed frame of Self-resetting module also can bear horizontal force) by support, thus makes agent structure post only bear vertical load, and effectively reduces column section area; Under large shake effect, support surrender and produce comparatively large plastometric set, prestressed frame still has lateral resistant ability, and therefore module can ensure that structure has two defence lines, road.Structure recovery original position is made by prestress wire after large shake, and only need replacing to support, more simple and convenient, thus realize structure after experience earthquake development plasticity, still can return to original position and there is no permanent set, shorten maintenance time, reduce maintenance cost and the target come into operation as early as possible.
