Compared with prior art the invention has the characteristics that and beneficial effect：
The present invention is based on finite element theory, sets up FEM (finite element) model and carries out mechanical analyses to assembled mixing coupled wall system, tests
Demonstrate,prove its reliability of structure, this system, compared with concrete shear wall structure system, has that anti-seismic performance is good, is easy to after macroseism shake
The advantage repaired；Compared with using traditional cast-in-place mode, build guality easily ensures, environmental protection performance is good；With existing assembled
Shear wall is compared, have the advantages that flexible design, make efficiently, convenient transportation, install convenient, good in economic efficiency, concrete manifestation
In the following aspects：
1st, anti-seismic performance is good：The present invention relies on pre-buried seam girder steel section that each wall unit is connected into mixing coupled wall system,
Under earthquake repeated action, so that pre-buried seam beam exposed parts preferably form shearing-type surrender, it consumes this structural system
Energy mode is similar to the power consumption of accentric support energy dissipating beam section, has the characteristics that energy dissipation capacity is big, it is little to deform, pre-buried seam girder steel section can
Along structure overall height arrangement, just as being provided with a considerable number of " electric fuse " in the structure, to be consequently formed preferable power consumption mechanism；
Compared with concrete connecting-beam, the former shear yielding energy-dissipating property is better than concrete connecting-beam beam-ends plastic hinge and consumes energy, and the former cuts
Cut surrender energy consumption and distortion little, under severe earthquake action, progressive collapse-resisting ability is strong.
2nd, it is easily repaired after macroseism shake：The energy passing to structure under macroseism is mainly by pre-buried seam beam and coupling beam to mould
Property deformation form absorbed, under severe earthquake action, delay the development in crack, preferably avoid or decrease shear wall bottom
Crack extension.Therefore, repairing after macroseism only need to carry out exposing the replacing of pre-buried seam girder steel section or coupling beam and open on a small quantity
Split the reinforcement that body of wall does.
3rd, optimization of construction technology, build guality is easy to ensure：The making major part of body of wall is to complete in factory, therefore may be used
Effective field surveillance is concentrated on the connection between wall element, engineering construction quality is easy to ensure；With cast-in-place coagulation
Native shear wall is compared, and factory is made and carried out with in-site installation simultaneously, solves cast-in-place concrete shear wall situ wet operation amount big
Problem；Compared with existing general fabricated shear wall, pre-buried seam post can solve asking of upper wall construction process stability
Inscribe, for realizing constructing with the crossings on different level that pours of the splicing of layer coupled wall unit scene and floor, there is provided technical probability；
Steel coupling beam substitutes concrete connecting-beam, solves the problems, such as that cast-in-place concrete coupling beam situ wet operation amount is big.
4th, environmental protection performance is good：The major part that makes due to body of wall completes in factory, and template can effectively repeat
Using pre-buried seam girder steel section, coupling beam are again without using template and temporary support, therefore building course decreases the product of building waste
Raw.
5th, flexible design, make efficiently, convenient transportation, install convenient：In existing prefabricated fabricated shear wall design, often
Be coupling beam, the body of wall that is connected with coupling beam two ends be divided into an assembly unit, cause unit volume excessive, to transport, install
Bring inconvenience；In addition, this kind of cell cube design, not only bring inconvenience to designer, and body of wall assembly unit
Standard component should not be formed, lead to mould utilization ratio low.This patent proposes to adopt intersegmental, the pre-buried seam steel of pre-buried seam girder steel
The mode being connected between beam section and coupling beam to realize the effectively connection between wall limb, is that structure design personnel flexibly design prefabricated unit
Provide convenience, be also beneficial to body of wall assembly unit simultaneously and form standard component；Pre-buried seam girder steel section is connected at the scene with coupling beam, just
Need not consider that the body of wall coupling beam and its two ends pours and build up a cell cube, thus convenient transport and installation；This patent is also upper
The pre-buried seam post of the connect setting of lower wall unit, saves the operation of its live temporary support, real " playing with building blocks " formula realized
Mode of construction, convenient installation.In a word, compared with existing fabricated shear wall, have flexible design, make efficiently, convenient transportation,
The advantages of install convenient.
6th, good in economic efficiency：At this stage, fabricated shear wall cost remains high, and traces it to its cause, mainly the just company of being because
The body of wall at beam and its two ends pours and builds up a big unit body, thus being transport and installation brings inconvenience；In addition it is exactly irregular wall
Body assembly unit, is difficult to form standard component, mould utilization factor is low, using pre-buried seam girder steel intersegmental, pre-buried seam girder steel section with
Between coupling beam, connected mode realizes the effectively connection between wall limb, and the problems referred to above can be readily solved, and substantially can reduce cost, highlight
The economic advantages of fabricated construction.
