Description
Technical field
The utility model relates to a kind of assembled steel reinforced concrete structure, relates in particular to a kind of reinforced concrete structure of printing based on 3D.
Background technology
Assembled steel reinforced concrete structure is an important directions of building structure development, is conducive to the development of industrialization of construction industry, the energy conservation of enhancing productivity and development Green environmental-protection building.Having a kind of good assembled steel reinforced concrete structure is to adopt the cast-in-place assembled steel reinforced concrete structure of building of the prefabricated core of shell, and its concrete cover by the beam of assembled steel reinforced concrete structure, post member is prefabricated together with stirrup, forms degree of lip-rounding precast concrete shell; Shell assembling and positioning also configures after main muscle, builds core concrete in shell, and so not only convenient construction but also save template, is conducive to industrialization of construction industry.
But, binding ability between inner surface and the inner concrete of the cast-in-place precast concrete shell of building assembled steel reinforced concrete structure of the prefabricated core of this shell is not high, easy to shell, does not also have at present good method to solve the adhesion problem between inner surface and the inner concrete of precast concrete shell.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easy construction, can improve the bond strength between precast concrete shell and interior note concrete, avoids reinforced concrete structure and the construction method printed based on 3D of shelling.
For realizing above-mentioned technique effect, the utility model discloses a kind of reinforced concrete structure of printing based on 3D, described structure comprises the precast concrete shell of a 3D printing shaping and builds the concrete in described precast concrete shell, the inner surface of described precast concrete shell is formed with concave convex texture, for strengthening the bond strength between inner surface and the described concrete of described precast concrete shell.
The utility model further improves and is, described concave convex texture is curved.
The utility model further improves and is, described concave convex texture is polygon.
The utility model, owing to having adopted above technical scheme, makes it have following beneficial effect:
By adopting the construction of the reinforced concrete structure of printing based on 3D, replace original pouring template construction, not only can be used as the template of reinforced concrete structure with the integrated precast concrete shell of 3D printing technique, itself also can serve as a part for reinforced concrete structure, therefore, avoid after reinforced concrete structure concreting, the construction of stripping, save working procedure, saved template, be conducive to industrialization of construction industry.
By adopting the one-body molded precast concrete shell of 3D printing technique, on the inner surface of precast concrete shell, form continuous concave convex texture, increase the contact surface between precast concrete shell interior note concrete and its inner surface, compare level and smooth inner surface, increase frictional force, improve bond strength, avoided shelling phenomenon.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
First consult shown in Fig. 1, a kind of reinforced concrete structure 10 of printing based on 3D of the present utility model main by precast concrete shell 11, be arranged at the bar construction 12 in precast concrete shell 11, and the concrete of building in precast concrete shell 11 forms.Coordinate shown in Fig. 2 and Fig. 3, Fig. 2 is a kind of precast concrete shell 11 of beam, precast concrete shell 11 adopts the printing integrated moulding of 3D, and inner surface is formed with concave convex texture 13 continuously, concave convex texture 13 is curved, can increase the contact surface between concrete and precast concrete shell 11 inner surfaces, compare level and smooth inner surface, increase frictional force, improved bond strength, avoided shelling phenomenon.Coordinate shown in Fig. 3 and Fig. 4, the concave convex texture forming on precast concrete shell 11 inner surfaces can be to be polygon, as the shape such as triangle, rectangle, can reach the effect of the bond strength between maximum precast concrete shell 11 inner surfaces and interior note concrete.
In the time utilizing precast concrete shell 11 of the present utility model to carry out the construction of reinforced concrete structure, comprise following construction sequence:
A, construction sole plate 14 are upwards reserved the section of plugging into 15, as shown in Figure 6 on the bar construction of sole plate 14;
B, in the section of plugging into 15 bar construction 16 of binding structure post, as shown in Figure 7, the reinforcing bar section of plugging into of reserved structural beams machine superstructure on bar construction 16;
C, employing 3D printing technique making shape adapt to the precast concrete shell 11 of structural column, and as shown in Figure 1, shape is square shape, and the inner surface of precast concrete shell 11 forms concave convex texture 13;
D, the precast concrete shell of structural column 11 is sheathed on from top to bottom on the bar construction 16 of structural column, the bottom of precast concrete shell 11 is connected on sole plate 14, and sealing rod 17 is set between precast concrete shell 11 and basic floor 14 and carries out anti-seepage construction, as shown in Figure 8;
The bar construction 18 of e, binding structure beam, and by 18 colligations of the bar construction of structural beams to the bar construction 16 of structural column, as shown in Figure 9;
F, employing 3D printing technique making shape adapt to the precast concrete shell 11 of structural beams, and as shown in Figure 2, it is U-shaped that shape is, and the inner surface of precast concrete shell 11 forms concave convex texture 13;
