It is that the precast concrete shell of the structural column is sheathed with into the knot that the construction method is further improved
After on the bar construction of structure post, to carrying out anti-seepage construction between the precast concrete shell and the basic floor.
The invention also discloses a kind of reinforced concrete structure based on 3D printing, the structure includes the pre- of 3D printing shaping
Concrete casing processed and pour in the concrete in the precast concrete shell, the inner surface shape of the precast concrete shell
Into there is concave convex texture, for strengthening the bond strength between the inner surface of the precast concrete shell and the concrete.
It is that the concave convex texture is curved that the structure is further improved.
The structure is further improved, and the concave convex texture is in polygon.
The present invention makes it have following beneficial effect as a result of above technical scheme：
By the construction using the reinforced concrete structure based on 3D printing, replace original pouring template construction, with 3D printing
The integrally formed precast concrete shell of technology acts not only as the template of reinforced concrete structure, and itself also can be used as reinforced concrete
A part for structure, therefore, it is to avoid after reinforced concrete structure concreting, the construction of form removal saves construction work
Sequence, saves template, is conducive to building industrialization.
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 contact surface between note concrete and its inner surface in precast concrete shell is increased, compared to flat
Sliding inner surface, increases frictional force, improves bond strength, it is to avoid shelling phenomenon.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the present invention is further detailed explanation.
Referring initially to shown in Fig. 1, a kind of reinforced concrete structure 10 based on 3D printing of the invention is main by precast concrete
Shell 11, the bar construction 12 being arranged in precast concrete shell 11, and pour in the coagulation in precast concrete shell 11
Soil is constituted.Coordinate shown in Fig. 2 and Fig. 3, Fig. 2 is a kind of precast concrete shell 11 of beam, and precast concrete shell 11 uses 3D
Printing integrated shaping, and inner surface has been formed continuously concave convex texture 13, concave convex texture 13 is curved, can increase concrete with it is pre-
Contact surface between the inner surface of concrete casing processed 11, compared to smooth inner surface, increases frictional force, improves with reference to strong
Degree, it is to avoid shelling phenomenon.Coordinate shown in Fig. 3 and Fig. 4, the concave convex texture formed on the inner surface of precast concrete shell 11 can be with
