Description
[technical field]
The utility model relates to the shear wall of civil engineering, particularly relates to a kind of combined concrete shear wall.
[background technology]
Modern architecture is had higher requirement to shock resistance that is high-rise and super highrise building, shear wall remains the main antidetonation component of high level, super high rise structure now, and it is widely used in Frame _ Shear Wall Structure, shear wall structure, framework-core wall structure, tube in tube structure.Along with the development of modern tall structure, for meeting the needs of overall structure side direction antidetonation, traditional reinforced concrete shear wall important and influential persons enlarging section size, causes dead load to increase, add the reaction of violent earthquake further, and increasing section can cause the minimizing of actual usable floor area; Or use high-strength concrete to replace ordinary concrete to reach on the basis not increasing wall cross section, improve the lateral resisting ability of structure, but, although high-strength concrete intensity is high, but its plastic strain performance is deteriorated, and is difficult to meet deformation requirements under geological process.
At present, propose that a kind of bearing capacity is good, the novel shear wall of excellent earthquake resistance component-shear wall framed with CFST columns both at home and abroad, its feature is to strengthen shear wall with in the built-in shear wall of steel core concrete column.Because inner concrete retrains by the steel pipe of outsourcing effectively, thus the mechanical property of inner concrete is improved, not only supporting capacity improves greatly, and leads the deformability grow also making pillar due to the Gao Peigang in cross section.Steel core concrete column is placed in shear wall, not increasing under wall cross section or the condition reducing cross section, can ensure that shear wall has enough anti-lateral deformation capacities.But this class A of geometric unitA is subject to cross section and joins the impact of steel rate comparatively greatly, when cross section steel ratio is large, the lateral resistant ability of concrete-filled steel tube shear wall improves comparatively large, but also greatly increases the consumption of weight and steel, improves the cost of construction.
[summary of the invention]
The technical problems to be solved in the utility model is to provide that a kind of deadweight is low, steel consumption amount is little, cost is lower, and ensures that structure has the combined concrete shear wall of enough overall shock resistances.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is, a kind of combined concrete shear wall, comprise concrete body of wall and complex root PVC concrete pipe, complex root PVC concrete pipe is along the length direction spaced apart of concrete wall, and PVC concrete pipe is embedded in concrete wall vertically; Respectively comprise the grid screen of a reinforcing bar composition in the concrete wall of PVC concrete pipe array both sides, connected by steel tie between two grid screens.
Above-described combined concrete shear wall, PVC concrete pipe comprises pvc pipe and is poured into the concrete in pvc pipe.
Above-described combined concrete shear wall, described pvc pipe is Double-wall PVC bellows.
Above-described combined concrete shear wall, grid screen comprises transverse reinforcement and vertical reinforcement, and the spacing between transverse reinforcement is 2-6 times of pvc pipe diameter, and the spacing of vertical reinforcement is 2-6 times of pvc pipe diameter.
Above-described combined concrete shear wall, the horizontal spacing of PVC concrete pipe is 3-6 times of pvc pipe diameter.
Above-described combined concrete shear wall, PVC concrete pipe is arranged in the center being fixed the reinforcing cage formed by bearing rod and stirrup colligation.
Combined concrete shear wall deadweight of the present utility model is low, steel consumption amount is little, cost is lower, and ensures that structure has enough overall shock resistances.
[accompanying drawing explanation]
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model embodiment combined concrete shear wall.
Fig. 2 is that A in Fig. 1 is to sectional view.
[detailed description of the invention]
The structure of the utility model embodiment combined concrete shear wall as depicted in figs. 1 and 2, comprise concrete wall 1 and Duo Gen PVC concrete pipe, many PVC concrete pipe are along the length direction spaced apart of concrete wall 1, PVC concrete pipe is positioned over fixes by bearing rod 7 and stirrup 8 colligation the reinforcing cage center formed, and is embedded to vertically in concrete wall 1.
Respectively comprise the grid screen of a reinforcing bar composition in the concrete wall 1 of PVC concrete pipe array both sides, connected by steel tie 6 between two grid screens.
PVC concrete pipe is made up of Double-wall PVC bellows 2 and the concrete 3 be poured in Double-wall PVC bellows 2.
Grid screen comprises transverse reinforcement 4 and vertical reinforcement 5, and the spacing B1 between transverse reinforcement 4 is 2-6 times of Double-wall PVC bellows 2 diameter D, and the spacing B2 of vertical reinforcement 5 is 2-6 times of Double-wall PVC bellows 2 diameter D.
The horizontal spacing B3 of PVC concrete pipe is 3-6 times of Double-wall PVC bellows 2 diameter D.
The strength grade being poured into the concrete 3 in Double-wall PVC bellows 2 is C50-C80.The strength grade of body of wall 1 outer concrete is C30-C60.
Transverse reinforcement 4 and vertical reinforcement 5 adopt II or I I I level reinforcing bar, and steel tie 6 adopts I level or II level reinforcing bar.
Reinforcing cage is formed in Nodes colligation by handling reinforcement 7 and lateral tie 8, and the spacing B4 at vertical direction of lateral tie is 2-3 times of Double-wall PVC bellows 2 diameter D.
The construction method of above-mentioned combined concrete shear wall, comprises the following steps:
1) along the length direction spaced apart Double-wall PVC bellows 2 of concrete wall 1, and Double-wall PVC bellows 2 is placed in reinforcing cage kernel of section place.
2) transverse reinforcement 4 and vertical reinforcement 5 are respectively placed in Double-wall PVC bellows 2 array both sides, and fix in its crosspoint colligation, form reinforcing bar grid screen.
