Description
Technical field
The invention discloses a kind of steel tube concrete core pillar prefabricated assembled shear-wall element of putting more energy into, be that one is easy to site-assembled, the seismic shear wall being prefabricated in the factory, belongs to building engineering field.
Background technology
In today of builing industry fast development, building has been proposed to higher low-carbon (LC), green, environmental protection, efficient construction requirements, building structure is split into some building units, in factory, carry out prefabricated, the scene of being transported to is carried out assembled, thereby has eliminated the environment pollution such as airborne dust, noise of construction site, and production efficiency improves, saves a large amount of costs of labor, as making automobile, build house, started the new revolution of an industrialization of construction industry.
In the building of prefabrication and assembly construction, the antidetonation in house is crucial, in conventional reinforced concrete shear wall, need to arrange that a large amount of reinforcing bars resist seismic shear, the processing that current domestic factory carries out the goods such as reinforced mesh, reinforcing cage does not also realize mechanization completely, rely on to a great extent processing and the colligation of manually carrying out reinforcing bar, make shear force wall reinforcing steel bar processing and fabricating cost always high, and production efficiency is low, is difficult to supply with the demand of automation platform template production shear wall sheet.Therefore, need a kind of make simple, produce in factory speed fast and be convenient to the precast shear wall of on-site consolidation, require its shear behavior not to be weaker than ordinary reinforced concrete shear wall simultaneously, thereby improve the efficiency that prefabrication is produced.
Summary of the invention
The object of the invention is to the deficiency existing in producing for existing prefabricate ordinary reinforced concrete shear wall, a kind of steel tube concrete core pillar prefabricated assembled shear-wall element of putting more energy into is proposed, this scheme is easy to make, good integrity, and factory's reinforcing bar processing capacity is few, and on-the-spot splicing is convenient and reliable.
The present invention realizes with following technical scheme: a kind of steel tube concrete core pillar prefabricated assembled shear-wall element of putting more energy into, comprise double steel bar net sheet, external wrapping concrete and lacing wire, described double steel bar net sheet by the many vertical vertical reinforcements that distribute, be connected to many transverse reinforcements between many vertical reinforcements and the reserved dowel for being connected at two ends forms; Reserved dowel stretches out outside external wrapping concrete; Between double steel bar net sheet, fix with lacing wire drawknot; Also comprise many concrete filled steel tube stem stems, the many vertical equidistant intervals of concrete filled steel tube stem stem are fixed in the cavity forming between double steel bar net sheet; External wrapping concrete is built rear entirety and is wrapped on reinforced mesh and concrete filled steel tube stem stem; Stretch out outside external wrapping concrete at the described upper and lower two ends of concrete filled steel tube stem stem, and the concrete column core that described concrete filled steel tube stem stem is poured in round steel pipe cavity after by round steel pipe and site assembly forms.
The diameter of described concrete filled steel tube stem stem is 100-200mm, and the spacing between concrete filled steel tube stem stem is 6-10 times of concrete filled steel tube stem stem diameter.
The upper and lower end of described concrete filled steel tube stem stem stretches out external wrapping concrete 50-200mm, and reserved dowel stretches out external wrapping concrete 100-500mm to the left and right.
In ordinary reinforced concrete shear wall, embed steel tube concrete core pillar and replaced the vertical shear reinforcement of a part, utilize high-bearing capacity and the high ductility of concrete filled steel tube, the Compressive Bearing Capacity, the shear-carrying capacity that effectively improve shear wall, have good shock resistance etc.The present invention is prefabricated in the factory, and when application, needs only shear-wall element on-site consolidation.
The invention has the beneficial effects as follows: member construction technology of the present invention is simple, the making amount of labour is little, by prefabrication, on-site consolidation, can guarantee the total quality of building, improves construction operation speed, reduces labor operation intensity.
