Embodiment
The interval steel pipe of the present invention is carried out with combined concrete shear wall system below in conjunction with schematic diagram more detailed
Description, which show the preferred embodiments of the present invention, it should be appreciated that those skilled in the art can change described here
Invention, and still realize the advantageous effects of the present invention.Therefore, description below is appreciated that for those skilled in the art's
It is widely known, and it is not intended as limitation of the present invention.
It is an object of the invention to provide a kind of new building shear walls design, manufacture and construction method --- an inter-species
Every steel pipe and combined concrete shear wall system.The combined shear wall system of the present invention is a kind of beyond tradition steel pipe bundle shearing
Wall, it is adaptable to the structure stress wall in assembling building, by the combination of steel pipe and batten plate, forms steel pipe arranged for interval,
Used between steel pipe and casting concrete is reproduced after template, form shear wall；Rectangular steel pipe arranged for interval so that floor beam, plate exist
Position without steel pipe can be penetrated continuously so that more preferably, building globality is stronger for flooring horizontal force.
Specifically, as shown in Figures 1 to 4, interval steel pipe proposed by the present invention and combined concrete shear wall system, including
Steel pipe 1, batten plate 2, template 3, grout hole 5 etc..Wherein, steel pipe 1 is hollow long strip type rod member, and the section of steel pipe 1 is enclosed type section
Face, such as rectangle, square or circular, it is therefore preferable to rectangular or square.Template 3 can use aluminum alloy pattern plate, steel form, plank sheathing
Or precast concrete form, the template 3, which has, also serves as insulation, the effect of decoration.
As shown in figure 1, being the shear wall bone being made up of vertical spaced apart steel pipe 1 and the batten plate 2 being arranged laterally at a spacing
Frame 100, template 3 is respectively arranged with along the both sides in the extension direction of shear wall skeleton 100.
Wherein, the interior intracavitary of steel pipe 1 is cast with grouting material, the spacing of steel pipe 1 can according to design it needs to be determined that so that wall chi
Very little flexibility is greatly increased.Such as steel pipe width 200mm, and steel pipe clear spacing 300mm, you can 500mm is made a list
Member, two units are exactly 1 meter, are not only convenient for design, and consider very reasonable from loading angle.Most of all, between steel pipe 1
Every arrangement so that floor beam, plate can be penetrated continuously at the position without steel pipe, make flooring horizontal force more preferably, the globality of building
It is stronger.
Wherein, batten plate 2 is located between steel pipe 1 and along the height bearing of trend spaced set of steel pipe 1, and the spacing is generally
300~600mm, batten plate 2 is used to connect two adjacent steel pipes 1, so that metope forms entirety, is set on batten plate 2
There is reservation member 4.Directly template 3 can be arranged on shear wall skeleton 100 by the reservation member 4 of batten plate 2.Reservation member 4 is mixed
Solidifying soil is stayed in wall after pouring, and can be used as connection when next step construction heat-insulating and decorative wall panels.By cleverly
Size design so that the spacing of these reservation members 4 meets the requirement of modulus, further improves wall assembling and standardization.
Above-mentioned batten plate 2 includes lacing I21, the lacing II22 be arrangeding in parallel, and between lacing I21, lacing II22
Reservation member 4.The reservation member 4 is generally the reserved column piece of hollow cylinder shape.
For the ease of installation of the template 3 on shear wall skeleton 100, the structure of reserved column piece 4 can use following two
Form：
