Abstract

The invention discloses a 3D-printing-based concrete shear wall structure with concave-convex lines. The 3D-printing-based concrete shear wall structure comprises a 3D-printing-formed precast concrete shell and concrete poured into the precast concrete shell. The precast concrete shell comprises an inner wall, an outer wall and two side walls arranged on the two sides of the inner wall and the outer wall, and the inner wall, the outer wall and the side walls are integrally formed through 3D printing. A plurality of pulling ribs are connected between the inner wall and the outer wall, and the two ends of each pull rib are embedded in the inner wall and the outer wall respectively when 3D printing is carried out on the precast concrete shell. The concave-convex lines are formed on the surface of the precast concrete shell. Due to the fact that the precast pulling ribs are precast between the inner wall and the outer wall of the precast concrete shell, formwork swelling is prevented; moreover, horizontal ribs of the shear wall are pre-buried between precast concrete shells, the construction inconvenience caused after the horizontal ribs are installed is avoided, and construction is simplified.

Description

There is the concrete shear wall structure printed based on 3D of concave convex texture
The present invention is that the Chinese patent application of Application No. 201410437818.X is " based on mixing that 3D prints Solidifying soil shear wall structure and construction method thereof " divisional application of (applying date: on 08 29th, 2014).
Technical field
The present invention relates to a kind of shear wall construction field, particularly relate to a kind of have concave convex texture based on 3D The concrete shear wall structure printed.
Background technology
Traditional shear wall construction uses cast-in-place concrete construction, first colligation shear force wall reinforcing steel bar cage, including cutting Power wall horizontal bar and shear wall erect muscle, after steel reinforcement cage colligation completes, install shear wall formwork in steel reinforcement cage both sides, And use the mode wearing tension rib to carry out drawknot, to prevent later stage concreting the template of both sides During rise mould, in template, finally pour shear wall concrete, form removal after concrete final set, Complete construction.
Traditional cast-in-place concrete shear wall working procedure is numerous and diverse, and cannot be adapted to fabricated reinforced concrete knot Structure, the scope of application is little, is unfavorable for the development of building structure.
Assembled steel reinforced concrete structure is an important directions of building structure development, beneficially building industrialization The energy and development Green environmental-protection building are saved in development, raising production efficiency.There is a kind of preferably assembled steel Muscle concrete structure is to use the cast-in-place assembled steel reinforced concrete structure built of shell preformed core, and it is by assembled steel reinforced concrete The beam of structure, post component concrete cover prefabricated together with stirrup, formed degree of lip-rounding precast concrete shell； After shell assembling positions and configures main muscle, in shell, pour core concrete, the most both convenient construction Save again template, beneficially building industrialization.
But, this precast reinforced concrete structure is owing to cannot install tension rib, it is impossible to be applicable to shearing The construction of wall, therefore, how necessary proposition one installs tension rib in precast concrete shell is prevented The modulus problem that rises only occurred during casting concrete.
Summary of the invention
The technical problem to be solved be to provide a kind of have concave convex texture based on 3D print mixed Solidifying soil shear wall structure, it is possible to prevent the mould that rises, and, on the premise of ensureing quality and safety, save material Material, manpower, time cost etc., meet green construction requirement.
For realizing above-mentioned technique effect,
The invention discloses a kind of concrete shear wall structure printed based on 3D with concave convex texture, bag Include the precast concrete shell of 3D printing shaping and pour the coagulation in described precast concrete shell Soil, described precast concrete shell includes using an inner wall surface of the printing integrated molding of 3D, a wall face Be located at the both sides metope of described inner wall surface and described wall face both sides, described inner wall surface and described exterior wall Connecting between face and have tension rib described in multiple tracks, the two ends of described tension rib print described concrete at 3D It is embedded in respectively in described inner wall surface and described wall face during soil shell；Described precast concrete shell Surface is formed with concave convex texture.
The described concrete shear wall structure based on 3D printing with concave convex texture further improves In, described concave convex texture be consecutively formed at described precast concrete shell described inner wall surface, described outside On the inner surface of metope and described both sides metope.
The described concrete shear wall structure based on 3D printing with concave convex texture further improves In, the two ends of described tension rib bend up or down.
The described concrete shear wall structure based on 3D printing with concave convex texture further improves In, also it is included in when 3D prints described precast concrete shell and is embedded in described precast concrete shell Horizontal bar, and the vertical colligation perpendicular muscle on described horizontal bar before casting concrete.
The described concrete shear wall structure based on 3D printing with concave convex texture further improves In, described horizontal bar is parallel to described inner wall surface and described wall face, and the two ends of described horizontal bar are buried underground respectively In the metope of described both sides, described perpendicular muscle is vertically inserted in described precast concrete shell, and colligation is in institute State the inner side of horizontal bar.
Due to the fact that and have employed above technical scheme so that it is have the advantages that
By using the construction of the reinforced concrete structure printed based on 3D, replace original pouring template construction, with The integrated precast concrete shell of 3D printing technique, such as inner wall surface and the wall face of shear wall, not only may be used Using the template as shear wall, itself also can be as a part for shear wall, therefore, it is to avoid at shearing After wall concreting, the construction of form removal, save working procedure, save template, be conducive to building Build industrialization.
By when making precast shear wall inner wall surface and wall face, arranging between inner wall surface and wall face and draw Knot muscle, prevent from rising during concreting mould, and the horizontal bar of shear wall is embedded in the most in advance inner wall surface and Between wall face, it is to avoid the construction inconvenience brought is installed after horizontal bar, simplifies construction.
By using the one-body molded precast concrete shell of 3D printing technique, at the interior table of precast concrete shell Form continuous print concave convex texture on face, add the inner surface of precast concrete shell with its in note concrete it Between contact surface, compare smooth inner surface, increase frictional force, improve bond strength, it is to avoid be de- Shell phenomenon.
