Description

The concrete shear wall structure based on 3D printing with concave convex texture
The present invention is the Chinese patent application " concrete shear force wall based on 3D printing of Application No. 201410437818.X Structure and its construction method " (applying date：On 08 29th, 2014) divisional application.
Technical field
The present invention relates to a kind of shear wall construction field, more particularly to a kind of mixing based on 3D printing with concave convex texture Solidifying soil shear wall structure.
Background technology
Traditional shear wall construction uses cast-in-place concrete construction, binds shear force wall reinforcing steel bar cage, including shear wall water first Flat muscle and shear wall vertical bars, after the completion of steel reinforcement cage binding, install shear wall formwork, and the template of both sides is adopted in steel reinforcement cage both sides Carried out with the mode for wearing tension rib to drawing drawknot, to prevent the mould that rises in later stage concreting process, most after template Shear wall concrete is inside poured, the form removal after concrete final set, completes construction.
Traditional cast-in-place concrete shear wall working procedure is numerous and diverse, and can not be adapted to fabricated reinforced concrete structure, fits It is small with scope, it is unfavorable for the development of building structure.
Assembled steel reinforced concrete structure be building structure development an important directions, be conducive to building industrialization development, Improve production efficiency and save the energy and development Green environmental-protection building.It is using outer to have a kind of preferable assembled steel reinforced concrete structure The cast-in-place assembled steel reinforced concrete structure built of shell preformed core, it protects the concrete of the beam of assembled steel reinforced concrete structure, column component Sheath is prefabricated together with stirrup, forms degree of lip-rounding precast concrete shell；Shell assembling positions and after configuring main reinforcement, in being poured in shell Core concrete, had so not only facilitated construction but also had saved template, and be conducive to building industrialization.
But this precast reinforced concrete structure can not be suitable for applying for shear wall due to that can not install tension rib Work, it is therefore, necessary to propose to send out when how one kind installs tension rib to prevent casting concrete in precast concrete shell The raw modulus problem that rises.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of concrete based on 3D printing with concave convex texture and cut Power wall construction, can prevent the mould that rises, also, save material, manpower, time cost on the premise of quality and safety is ensured Deng meeting green construction requirement.
To realize above-mentioned technique effect,
The invention discloses a kind of concrete shear wall structure based on 3D printing with concave convex texture, including 3D printing Molding precast concrete shell and pour in the concrete in the precast concrete shell, the precast concrete shell bag Include using the integrally formed inner wall surface of 3D printing, a wall face and arranged on the both sides of the inner wall surface Yu the wall face both sides Metope, is connected with tension rib described in multiple tracks, the both ends of the tension rib are in 3D printing between the inner wall surface and the wall face It is embedded in respectively during the precast concrete shell in the inner wall surface and the wall face；The table of the precast concrete shell Face is formed with concave convex texture.
The concrete shear wall structure based on 3D printing with concave convex texture, which further improves, to be, described recessed Burr road is consecutively formed at the interior table of the inner wall surface of the precast concrete shell, the wall face and the both sides metope On face.
The concrete shear wall structure based on 3D printing with concave convex texture, which further improves, to be, the drawing The both ends of knot muscle are bent up or down.
The concrete shear wall structure based on 3D printing with concave convex texture, which further improves, to be, is further included The horizontal bar being embedded in when precast concrete shell described in 3D printing in the precast concrete shell, and in pouring coagulation Vertically bound before soil in the vertical bars on the horizontal bar.
The concrete shear wall structure based on 3D printing with concave convex texture, which further improves, to be, the water Flat muscle is embedded in the both sides metope respectively parallel to the inner wall surface and the wall face, the both ends of the horizontal bar, institute State vertical bars to be vertically inserted in the precast concrete shell, and bind in the inner side of the horizontal bar.
The present invention makes it have following beneficial effect as a result of above technical scheme：
By using the construction of the reinforced concrete structure based on 3D printing, original pouring template is substituted to construct, with 3D printing The integrally formed precast concrete shell of technology, such as the inner wall surface and wall face of shear wall, acts not only as the mould of shear wall Plate, therefore itself, can be also avoided after shear wall concreting, form removal is applied as a part for shear wall Work, saves working procedure, saves template, is conducive to building industrialization.
By the way that when making precast shear wall inner wall surface and wall face, tension rib is set between inner wall surface and wall face, Prevent the mould that rises during concreting, and the horizontal bar of shear wall is also embedded between inner wall surface and wall face in advance, avoid Construction inconvenience, simplifies construction caused by being installed after horizontal bar.
Precast concrete shell is integrally formed by using 3D printing technique, the shape on the inner surface of precast concrete shell Into continuous concave convex texture, the inner surface of precast concrete shell and the contact surface in it between note concrete are added, is compared Smooth inner surface, increases frictional force, improves bond strength, avoids shelling phenomenon.
