Problem；Compared with existing general fabricated shear wall, pre-buried seam post can solve asking for upper wall construction process stability
Topic, to realize that the splicing of same layer coupled wall unit scene is constructed with the crossings on different level that pours of floor, there is provided technical possibility；
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：Because the making major part of wall is completed in factory, template can be repeated effectively
Utilize, pre-buried seam girder steel section, coupling beam are again without using template and temporary support, therefore building course reduces the product of building waste
It is raw.
5th, flexible design, make efficiently, convenient transportation, install convenient：In existing prefabricated assembled shear walls design, often
It is that the wall that coupling beam is connected with coupling beam two ends is divided into an assembly unit, causes unit volume excessive, to transport, installs
Bring inconvenience；In addition, this kind of cell cube design, not only brings inconvenience to designer, and wall assembly unit
Standard component should not be formed, causes mould utilization ratio low.This patent proposition pre-buried seam girder steel of use is intersegmental, pre-buried seam steel
The mode connected between beam section and coupling beam realizes the effective connection between wall limb, is structure design personnel flexibly design prefabricated unit
Provide convenience, while also forming standard component beneficial to wall assembly unit；Pre-buried seam girder steel section is connected at the scene with coupling beam, just
The wall of coupling beam and its two ends need not be considered to pour and to build up a cell cube, so that 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, it is convenient to install.In a word, compared with existing fabricated shear wall, with flexible design, make efficiently, convenient transportation,
The advantages of install convenient.
6th, it is good in economic efficiency：At this stage, fabricated shear wall cost remains high, to find out its cause, main just because even
Beam is poured with the wall at its two ends and builds up a big unit body, so as to be that transport and installation bring inconvenience；It is exactly in addition irregular wall
Body assembly unit, is difficult to form standard component, and mould utilization factor is low, using pre-buried seam girder steel is intersegmental, pre-buried seam girder steel section with
Effective connection between connected mode realizes wall limb between coupling beam, above mentioned problem can be readily solved, and can substantially reduce cost, highlight
The economic advantages of fabricated construction.
