Traditional 3D printing technique is designed a model with Computerized three-dimensional as source, by software hierarchy is discrete and numerical control at Type system, in the way of laser beam, hot melt nozzle etc. by the special materials such as metal powder, ceramic powders, plastics, cell tissue into Row successively cohere by accumulation, and final superposition molding produces physical product.This Digitized manufacturing mode does not need complicated work Skill does not need numerous manpowers, can generate the components of any shape directly from computer graphics data, and precision and It is of high quality, thus 3D printing will be the revolution manufactured.

In view of this, the utility model proposes the 3D printing reinforced concrete members of a kind of simple process, quick construction.

The utility model is described in detail in the following with reference to the drawings and specific embodiments.

Referring initially to shown in Fig. 1 and Fig. 2, the embodiments of the present invention provide a kind of 3D printing armored concrete structure Part is mainly included precast reinforced skeleton 11, is successively printed on using 3D printing technique concrete on precast reinforced skeleton 11 Shell 12, and the core grouted concrete 13 for being perfused and being incorporated into inside each layer concrete shell 12 printed.

Wherein, 3D printing technique includes: current stereolithography art (SLA method), the laser sintered method (SLS of layering Method), successively contoured method (LOM method), photomask method (SGC method), melt deposition method (FDM method), ceramic shell process (DSPC method).

The 3D printing reinforced concrete member of the present embodiment is 3D printing reinforced column, wherein concrete casing 12 It can be rod structure shell made of by the way that molding 3D printing technique printing is printed, stacked based on layering, including composition column bottom The 3D printing pedestal 121 in face and the multiple 3D printing side plates 122 for constituting shaft surface, wherein 3D printing pedestal 121 and multiple 3D It prints side plate 122 to be integrally formed using 3D printing technique, inside is surrounded to form grouting space, and core grouted concrete 13 is poured into the filling It is combined into one in slurry space and with concrete casing 12.

As shown in Figure 1, precast reinforced skeleton 11 include lower end be inserted in multiple tracks vertical reinforcement in 3D printing pedestal 121 and Hoop is set to the multiple tracks stirrup of the periphery of multiple tracks vertical reinforcement.The inner surface of concrete casing 12 is incorporated into precast reinforced skeleton 11 Outside.

The characteristics of the utility model, is: core grouted concrete 13 be poured into the inside of not solidified concrete casing 12 and with Concrete casing 12 solidifies together.

Wherein, concrete casing 12 includes to print one section of height from the bottom to top as multiple printing lists of an elementary layer First layer, core grouted concrete 13 include the filling core unit layer for being perfused and being incorporated into the inside of every layer of print unit layer.

The 3D printing reinforced column of the utility model embodiment first binds precast reinforced skeleton, then in construction Core grouted concrete is perfused simultaneously in printing concrete casing, to complete the 3D printing of reinforced column.It avoids and is beaten successively It needs manually to place the links such as horizontal bar, the vertical muscle of binding during print, improves the degree of automation and construction effect of entire process Rate.Simultaneously by control print speed and rate of flooding, guarantee printing shell and inner core concrete perfusion synchronous construction, synchronous complete At realizing printing shell, perfusion inner core and framework of steel reinforcement and combine closely, to effectively improve the entirety of print component Property.

It does below with reference to the Specific construction process of the 3D printing reinforced column in the above-described embodiment of Fig. 3~8 pair into one Step is explained in detail and is demonstrated.

Column bottom shell, i.e. 3D printing pedestal 121 are made using 3D printing technique first, placement has been bound pre- above it Framework of steel reinforcement 11 processed, as shown in Figure 3 and Figure 4；

Then the 3D printing side plate 122 of column concrete casing 12 is from bottom to top printed (such as paragraph by paragraph using 3D printing technique Mono- section of 500mm), as shown in Figure 5 and Figure 6；Core grouted concrete 13, the filling core coagulation of perfusion are perfused in time into printing shell simultaneously Native 13 amounts and printing outer cover height maintain an equal level, as shown in Figure 7 and Figure 8, until construction is completed as depicted in figs. 1 and 2 in capital.

Preferably, the surface of the concrete casing 12 in the utility model embodiment is formed with concave convex texture and (does not show in figure Show), which can be the line of 3D printing process self-assembling formation, from the bottom to top continuous arrangement.

Continuous concave convex texture 14 can be set in the inner surface of concrete casing 12, at this point, utilizing the asperities of setting Road 14 can increase the inner surface of concrete casing 12 and the contact area of its internal core grouted concrete 13, enhancing the two Between bond strength, it is ensured that concrete casing 12 and core grouted concrete 13 condense integrally, anti-detachment.

It is, of course, also possible to continuous concave convex texture 14 be arranged in the outer surface of concrete casing 12, at this point, utilizing setting Concave convex texture 14 can beautify the outer surface of concrete casing 12, alternatively, increase concrete casing 12 outer surface and it is external its The binding ability of his component.

To improve the cementitiousness between integrally formed 3D printing concrete component unlike material structure, improve whole Intensity.
