Description

The method preventing the concrete shear force wall shelling printed based on 3D
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 coagulation preventing and printing based on 3D The method of soil shear wall shelling.
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 is to provide a kind of concrete shear force wall preventing from printing based on 3D and takes off The method of shell, it is possible to prevent the mould that rises, and save on the premise of ensureing quality and safety material, manpower, Time cost etc., meet green construction requirement.
For realizing above-mentioned technique effect, the invention discloses a kind of concrete shear force wall preventing and printing based on 3D The method of shelling, including step:
A, employing 3D printing technique making ground floor shape adaptation are in the precast concrete shell of shear wall, described Precast concrete shell includes an inner wall surface, a wall face and is located at described inner wall surface and described wall face both sides Both sides metope；The surface of described precast concrete shell is formed with concave convex texture；
B, ground floor tension rib and/or horizontal bar are set in the top of ground floor precast concrete shell；
C, employing 3D printing technique make second layer precast concrete in the top of ground floor precast concrete shell Shell, make the two ends of ground floor tension rib and/or horizontal bar be embedded in respectively ground floor precast concrete shell with The junction of second layer precast concrete shell；
D, repetition step b, c, until completing all layer precast concrete shells to designed elevation；
E, in all layer precast concrete shells, plug perpendicular muscle, described perpendicular muscle colligation in described tension rib and/ Or on horizontal bar；
F, in all layer precast concrete shells casting concrete, complete the construction of shear wall；
Wherein, the top of precast concrete shell described at least one of which is provided with described tension rib, and described in draw The two ends of knot muscle are respectively arranged on the top of described inner wall surface and described wall face.
The described method preventing the concrete shear force wall printed based on 3D from shelling further is improved by, described The two ends of tension rib bend up or down.
The described method preventing the concrete shear force wall printed based on 3D from shelling further is improved by, described Concave convex texture is consecutively formed at the described inner wall surface of described precast concrete shell, described wall face and institute State on the inner surface of both sides metope.
The method of the described concrete shear force wall shelling preventing from printing based on 3D is further improved by, in the The top of one layer of precast concrete shell arranges ground floor tension rib, uses 3D printing technique prefabricated in ground floor The top of concrete casing makes second layer precast concrete shell, makes the two ends of ground floor tension rib bury respectively It is located at the junction of ground floor precast concrete shell and second layer precast concrete shell；Then, in second The top of layer precast concrete shell arranges ground floor horizontal bar.
The described method preventing the concrete shear force wall printed based on 3D from shelling further is improved by, described Horizontal bar is parallel to described inner wall surface and described wall face, and the two ends of described horizontal bar are embedded in described two respectively In side wall；Described perpendicular muscle is vertically inserted in described precast concrete shell, and colligation is in described horizontal bar Inner side.
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.
