Technical field
The invention belongs to building structure technology field, be specifically related to the vertical piece node of one " one " font basement shear wall and construction method thereof.
Background technology
Shear wall is compartment wall and the enclosure wall of building, is generally steel concrete and builds and form.This body of wall had both born the vertical load that horizontal member transmits, and bore the horizontal loading that wind-force or geological process transmit simultaneously, also shear wall was called seismic structural wall, earthquake resistant wall in earthquake resistant code.Shear wall structure system has good supporting capacity, and has good globality and spatiality, has better lateral resisting ability than frame construction, is applicable to the building building 50-120 rice height.In shear wall and shear wall junction, need reliable node that shear wall is connected with shear wall and be an entirety, under the External Force Actings such as seismic forces, vertical counter-force and horizontal shear can be transmitted, ensure the safety of structure.The shear wall exterior wall of basement also bears the soil of surrounding or the lateral pressure of other fillers simultaneously, plays the native waterproof action of gear.
At present, shear wall yi word pattern connected node has a variety of, and a kind of Linear shear wall vertical connection node of the disclosure of the invention of the patent No. 200910028249.2, comprises the groove between the first precast shear wall, the second precast shear wall, shear wall and seam.Be provided with " L " type in shear wall and in groove and add muscle, the body of wall horizontal reinforcement of shear wall in groove side extends to forward the opposite side of close inside grooves at groove simultaneously, and bends inwards.The diameter of additional muscle is identical with body of wall horizontal reinforcement, and groove is 200mm along the length of wall direction, ensures that the length of additional muscle meets anchoring requirement.Adopt this invention, under the prerequisite ensureing the basic stress performance of structure, reduce amount of reinforcement, but between precast shear wall and cast-in-situ concrete, contact area is few, overall performance is not high, and Nodes is difficult to after there is crack control its development.
In view of this, the applicant provides a kind of vertical piece node of " one " font basement shear wall and construction method thereof, and this case produces thus.
Summary of the invention
A kind of shear wall that makes is the object of the present invention is to provide to connect at corner place for overall, that effectively control distress in concrete the development vertical piece node of one " one " font basement shear wall and construction method thereof.
For achieving the above object, the technical scheme that inventing specifically provides is: a kind of vertical piece node of " one " font basement shear wall and construction method thereof, comprise the overlaid plate type shear wall be made up of two interconnective first prefabricated overlaid plate type shear walls and the second prefabricated overlaid plate type shear wall, connected by prefabricated panel seam between described first prefabricated overlaid plate type shear wall and the second prefabricated overlaid plate type shear wall, described first prefabricated overlaid plate type shear wall and the second prefabricated overlaid plate type shear wall node place, be furnished with double longitudinal joint bar, this double longitudinal joint bar and stirrup colligation are connected to form like constructional column, the non-preformed layer of overlaid plate type shear wall and seemingly constructional column place are cast-in-situ concrete, are micro-expansion cement mortar in described prefabricated panel seam.
Further, described first prefabricated overlaid plate type shear wall should be consistent with the second prefabricated overlaid plate type shear wall wall thickness, and wall thickness is greater than 350mm.
Further, described double longitudinal joint bar is ￠ 12 grade III steel, and length is overlaid plate type shear wall height, and spacing is 400mm.
Further, described stirrup reinforcing bar type and size, with overlaid plate type shear wall horizontal bar, stretch into the first prefabricated overlaid plate type shear wall and the non-preform region size of the second prefabricated overlaid plate type shear wall is 400mm, and vertical interval is 200mm, and shear wall is logical highly to be arranged.
Further, the width of described prefabricated panel seam is 20mm.
The beneficial effect that the present invention reaches:
The present invention is had " effect of mould hoop " by the seemingly constructional column arranging longitudinal joint bar and stirrup formation at Nodes, can postpone the appearance in crack and the expansion in restriction crack to a certain extent, improve the durability of structure; Overlaid plate type shear wall is firmly connected by Cast-in-place concrete with like constructional column, and between Cast-in-place concrete and precast plate, contact surface is comparatively large, and node has good globality, can effectively bear and transmit vertically and the external force of horizontal direction, ensure the safe handling of building.
