[0028]请参考图1至图4,上述区块分布式单轴3D打印装置包括爬升装置(未图示)和打印装置40,爬升装置包括固定于已打印建筑体10的外立面的爬升导轨20以及能够沿着爬升导轨20相对于已打印建筑体10竖向移动的爬升构件30,爬升装置能够带动打印装置40相对于已打印建筑体10爬升或下降;打印装置40包括与爬升构件30顶端刚性连接的轨道框架(未图示)以及打印头横梁42,轨道框架包括若干相交固接的轨道横梁43和连系梁44组成的网格结构,轨道横梁43和连系梁44分别平行间隔设置,为了尽可能防止轨道横梁43产生挠度,使得连系梁44的两端分别与轨道框架边缘的轨道横梁43固定连接,连系梁44的中部固接于轨道框架内部的轨道横梁43的上方,网格结构的网格单元(一对平行间隔设置的轨道横梁43与另外一对平行且间隔设置的连系梁44首尾相接形成的一个水平框架结 [0028] Please refer to FIG. 1 to FIG. 4, the above-described block distributed single-axis 3D climbing device comprising printing means (not shown) and a printing device 40, including the climbing device is fixed to the printed climb the building facade member 10 rails 20 and 20 with respect to the guide rail 10 capable of vertical movement of the building body printed climb member 30, the climbing device can be driven along the printing device 40 with respect to the printed climb construction body 10 to climb or descend; printing means 40 comprises a member 30 climbs rigidly connected to the top rail frame (not shown) and print head cross member 42, the rail frame including a plurality of intersecting tracks cross member 43 fixedly attached to and associated with a grid structure consisting of beams 44, cross rail 43 and the associated beam 44 are parallel spaced setting, as much as possible in order to prevent the cross rail 43 generates deflection, so that the ends 44 of the continuous beam 43 are fixedly connected to the edge of the frame beam track rail, are associated with the top of the middle beam 44 fixed to the inner rail track frame beam 43 track beam grid mesh structure unit (a pair of parallel spaced horizontal frame 43 of a junction with another pair of parallel, spaced beams 44 arranged end to end to form a contact associated )的相邻且平行的两个轨道横梁43之间设置一根打印头横梁42,打印头横梁42两端能够沿着轨道横梁43滑动,每根打印头横梁42上密布打印头50。 ) Disposed adjacent to and between two rails 43 parallel to the cross beam 42 a print head, the cross member 43 can slide along the rail 42 at both ends of the cross member printhead, the print head 50 on the clouds 42 of each printhead beams.

[0029]前述刚性连接为焊接、螺栓连接等,本实施例优选螺栓连接,可实现打印装置40与爬升构件30的快速组装及拆卸。 [0029] The rigid connection of the welding, bolting, etc., the present embodiment is preferably bolted embodiment, the printing apparatus can achieve rapid assembly and disassembly 40 and 30 climb member. 另外需指出的是,打印装置40和爬升构件30均与动力控制系统通信连接,因动力控制系统不在本发明权利要求的保护范围内,故对其结构及连接关系不作具体阐述。 Further to be noted that, the printing apparatus 40 and climb member 30 are connected to the power control system in communication, because of the power control system within the scope of the claimed invention is not, so its structure and connection relationship is not specifically addressed. 由于爬升导轨20附着固定于已打印建筑体10的外立面,从而爬升导轨20可以采用逐步加长升高的方式随着已打印建筑体10的升高而升高,具体方法可以参照起重塔吊施工中塔身标准节的增高原理,此处不做赘述。 Since the climbing rail 20 is attached is fixed to the printed building facade member 10, whereby the guide rail 20 may climb elongated raised stepwise manner with increasing printed construction body 10 is raised, lifting crane can refer to a specific method construction increased in the tower section of the principle, not repeat them here. 而且为了保证爬升构件30的正常爬升,该爬升导轨20的高度大于对应的已打印建筑体10横截面层的高度。 And in order to ensure the normal climb climb member 30, the climbing height of the guide rail 20 is larger than the corresponding height of the printed layer 10 a cross-sectional construction thereof. 该爬升导轨20同时作为打印装置40的支撑装置。 The climbing apparatus 40 while supporting the guide rails 20 as the printing apparatus.

[0030]针对目前建筑体结构体量巨大,而现有3D打印装置不仅打印尺度有局限,打印精度不高,而且只有一个打印头,无法应用于大体量建筑物施工的缺陷,本发明的区块分布式单轴3D打印装置,在打印装置40的轨道框架上设置若干平行间隔设置的轨道横梁43,在轨道框架的另外两侧的连系梁44内增设若干平行且等间距设置的连系梁44,从而将打印装置40划分为若干个等面积的打印区块。 [0030] Aiming at the great structure building body mass, while the conventional 3D printing apparatus to print not only has limited scale, the printing accuracy is not high, and only one print head, generally can not be applied to the defect rate of the building construction, the region of the invention distributed block uniaxial 3D printing apparatus, a plurality of parallel disposed rails spaced beams 43 arranged on the rail 40 of the printing apparatus frame, a plurality of parallel and are associated with additional equally spaced in the beams associated with the other two sides of the track frame 44 beam 44, so that the printing device 40 is divided into several equal-area printing block. 与常规的仅由一对平行设置的轨道横梁43与一对平行设置的连系梁44组成的框架结构式轨道框架相比,本发明在轨道框架内增设若干平行且等间距设置的轨道横梁43,本发明的打印装置40中每个网格单元内的相邻的两个轨道横梁43之间设置一根打印头横梁42,打印头横梁42上密布能够独立控制的打印头50,从而将打印装置40的每个网格单元中XY平面内由双向移动打印变为单向移动打印,有效提高了3D打印装置40的可靠性,而且由于每根打印头横梁42上均密布打印头50,故无需移动打印头50,而仅需在XY水平打印面上移动一次打印头横梁42即可完成一个层横截面层的打印,显著提高了打印效率此外,将打印装置40划分为若干个等面积的打印区块,缩短了单根打印头横梁42的长度,减小了打印头横梁42的挠度,防止打印头横梁42产生竖向位移,而且打印头50与打印头 Compared to the frame structure of track frame and a conventional rail cross member is provided only by a pair of parallel 43 associated beam 44 and a pair of parallel arranged compositions, the present invention is the addition of the track number of parallel and equally spaced cross member 43 within the track frame, 43 disposed between adjacent grid units within each two cross rails 40 of the printing apparatus according to the present invention, a beam print head 42, the print head can be controlled independently clouds of the print head 50 on the beam 42, so that the printing means each grid cell 40 within the XY plane is printed by bidirectional printing movement becomes unidirectional movement, effectively improves the reliability of 3D printing device 40, and since the upper cross member 42 of each printhead are densely print head 50, so no moving the print head 50, and a print head moves only in the horizontal XY cross beam 42 to complete the printing surface printing layer is a layer cross-section, significantly improved printing efficiency in addition, the print 40 is divided into several other areas of the printing apparatus block, shortens the length of a single print head beams 42, reduces the deflection of the beam 42 of the print head, the print head cross member 42 to prevent vertical displacement is generated, the print head 50 and the print head 梁42同步移动,也就是说,打印头50在打印头杆51的作用下,仅能够改变垂直方向的伸长量,而不可沿着打印头横梁42滑动,从而提高了打印精度。 Beams 42 move synchronously, that is, the print head 50 under the action of the print head 51 bar, can be changed only in the vertical direction of elongation, and can not cross member 42 slides along the print head, thereby improving the printing accuracy. 当然,通过在已打印建筑体10外立面设置爬升导轨20,爬升构件30在动力控制系统的控制下沿着爬升导轨20进行爬升和下降运动,而爬升构件30与轨道框架固定连接,从而使得爬升构件30能够带动打印装置40逐步相对于已打印建筑体1逐步地相对于已打印建筑体I沿z轴向上移动,进而使得打印装置40在自动化爬升的同时完成建筑体各横截面层自下向上的逐层打印施工。 Of course, by providing the printed building facade member 10 climbs the guide rails 20, 20 to climb along the guide rail member 30 to climb under the control of the power control system and lowering movement is climbing, climbing and the rail 30 is fixedly connected to the frame member, such that climb member 30 can be driven stepwise with respect to the printing apparatus 40 has printed the building body 1 gradually with respect to body I printed building moves along the z axis, thereby making the printing apparatus 40 to complete the construction of each cross-sectional layer of the body at the same time from the automatic climb Print the bottom up layer by layer construction.

[0031]较佳地,本实施例打印装置40的打印头横梁42的两端设有滑块45,轨道横梁43上设有与滑块45滑动配合且横截面呈C形的滑道(未图示),使得打印头横梁42的两端能够沿轨道框架的滑道(即X轴方向)自由滑动。 [0031] Preferably, the printing apparatus of the present embodiment, the print head 40 at both ends of the cross member 42 is provided with a slider 45, provided with cross-sectionally C-shaped guide rail 45 and a slider slidably fitted on the rail beam 43 (not illustrated), both ends of the cross member 42 such that the print head can freely slide along the slide rails of the frame (i.e., X-axis direction). 由于滑块45均能够安全可靠地嵌装在滑道的C形开口腔内,因此,上述结构能够保证打印头横梁42在轨道横梁43上稳定运行。 Since both the slider 45 can be securely fitted C-shaped cavity mounted in the opening slide, therefore, the above-described structure can ensure the stable operation of the print head 42 cross beam 43 on the track.
