The present invention is that presstressed reinforcing steel and steel pipe concrete frame compound shear wall are carried out advantageous combination, using by prestressing force
Muscle is arranged in the construction in the steel pipe concrete frame column of the larger lower region of shear wall stress, has not only given full play to steel pipe
The excellent anti-seismic performance of concrete frame shear wall also takes full advantage of the high-strength performance of unbonded prestressing tendon, and reaching can be extensive
Multiple effect.After adding presstressed reinforcing steel in the steel core concrete column of the novel compositions shear wall, have the function of with lower stress and
Feature：The steel core concrete column at wall both ends can effective confined concrete, improve the bearing capacity of concrete, enhance wall
Anti-seismic performance, and the ductility of steel pipe can preferably give full play to the deformability of steel, when by tension and compression load, due to pre-
Prestress steel strand or high tensile reinforcement are in soap-free emulsion polymeization state so that the steel pipe concrete frame of shear wall bottom is close under big shake
When surrender, the un-bonded prestressed steel strand or high tensile reinforcement that are arranged in steel pipe concrete frame are stretching also still in elasticity
Under load, pulling force is born by presstressed reinforcing steel first, until steel pipe zero stress state just starts steel pipe and presstressed reinforcing steel is born jointly
Pulling force, concrete filled steel tube stretcher strain reduction, steel pipe surrender delays, rod piece tensile capacity significantly improves, when tension load removes
Afterwards, stretcher strain can partly or entirely restore, and can reach reusable purpose through suitably repairing part is restored,
To make entire combined member that there is function restorability.Between steel core concrete column with frame girder steel connect, and with it is upper and lower
Frame beam consolidation, horizontal bar and steel-pipe welding, both sides bar-mat reinforcement tension rib drawknot make steel construction become one with concrete wall
A entirety effectively raises the globality of structure so that each section gives full play to respective performance, works together, and has complementary advantages.
A kind of recoverable steel pipe concrete frame compound shear wall of the present invention can with certain under geological process
It is restorative.In seismic energy input, reinforced concrete wall panel starts to play a role as one of anti-vibration defense lines, concrete filled steel tube
Frame also plays a role as another road defence line, and the deformation of wall can be constrained by applying prestressing force to presstressed reinforcing steel, and certain
The recoverable force for making wall in degree effectively reduces integrally-built displacement, improves concrete panel vertical bearing capacity and extensive
Multiple power.With the increase of input energy, for steel pipe concrete frame close to surrender, the interior soap-free emulsion polymeization being arranged of steel pipe concrete frame is pre-
Stress rib can constrain the displacement of wall still in elasticity.Relative shear compared to common this wall of Self-resetting wall is slided
Shifting is substantially reduced, and bearing capacity, ductility and energy dissipation capacity are more preferable than normal concrete shear wall, and later stage anti-seismic performance is stablized relatively,
Prestressing without bondn post-tensioning is easy for construction, can be used in high-rise or large complicated tier building.
When building meets with violent earthquake, its earthquake can be mitigated, there is part recoverable function, while also improving knot
The shock resistance and restoring force of structure entirety.

It is inserted into distribution bar (6) in the steel reinforcement cage of following grid beam or foundation beam (11), pours into a mould the mixed of following grid beam or foundation beam (11)
Solidifying soil ensures that the anchorage of presstressed reinforcing steel bottom is close to lower part backing plate, keeps vertical, it is ensured that presstressed reinforcing steel lower end is in anchor when pouring
Solid fraction state makes following grid beam or foundation beam (11) are vertically distributed with steel pipe concrete frame, shear wall after concrete curing consolidates
Rigid connection is realized in the bottom of reinforcing bar, and presstressed reinforcing steel lower part is in fixing end；
4) production technique reinforcing bar (5), and horizontal reinforcement and steel core concrete column are welded；With steel tie (7) by steel plate both sides
Horizontal reinforcement (5) and longitudinal reinforcement (6) socket；
5) top grid beam (10) is made, it is made to carry out rigidity with steel pipe concrete frame column (1) and the vertical distribution bar of wallboard (6)
Connection；
6) thickness of concrete cover is reserved by spacer in shear wall wallboard both sides, fixed in steel pipe concrete frame column
The position of bellows, and be allowed to keep vertical, the gap between bellows and presstressed reinforcing steel is sealed in bellows opening
It is stifled, the template of the concrete of branch cast later；
7) concrete for pouring steel pipe concrete frame column (1), shear wall wallboard, top grid beam (10), poured in engineering and put
Any concrete cannot be had by setting in the bellows of presstressed reinforcing steel, be demoulded after molding；
8) after being molded, remove the plugging material between bellows and presstressed reinforcing steel, it is ensured that the soap-free emulsion polymeization of presstressed reinforcing steel, in construction
In the reserved construction hole of stretching end, enough construction spaces are provided for tensioning equipment, using post stretching by tension of prestressed tendon to setting
Prestress value is counted, is used in combination anchorage (3) fixed, space forms a kind of recoverable steel pipe concrete frame compound shear wall.
