A first support rod 85 is fixedly arranged between the left steel template 4 and the first base 8 and between the right steel template 5 and the first movable rod. When the first movable rod of the first telescopic device 82 is extended, the left steel template 4 is stationary and the right steel template 5 moves to the right; when the first limiting rope 83 is straightened, the position of the right steel template 5 is determined, and then as the first movable rod of the first telescopic device 82 continues to extend, the force generated drives the first base 8 to start moving to the left, thereby the left steel template 4 moves to the left, and when the first limiting block 81 located at the right end of the first base 8 abuts against the support frame 1, the first movable rod is no longer extended, the first base 8 stops moving to the left, and the position of the left steel template 4 is determined. When the first movable rod of the first telescopic device 82 contracts, the left steel template 4 does not move, and the right steel template 5 starts to move to the left; when the first limit rod 84 abuts against the right steel template 5, the right steel template 5 stops moving to the left, and then as the first movable rod of the first telescopic device 82 continues to contract, the force generated drives the first base 8 to start moving to the right, thereby moving the left steel template 4 to the right, and when the first limit block 81 located at the left end of the first base 8 abuts against the support frame 1, the first movable rod no longer contracts, and the first base 8 and the left steel plate stop moving to the left.

A second support rod 95 is fixedly arranged between the lower steel template 7 and the second base 9 and between the upper steel template 6 and the second movable rod. When the second movable rod of the second telescopic device 92 is extended, the lower steel template 7 does not move, and the upper steel template 6 moves upward; when the second limit rope 93 is straightened, the position of the upper steel template 6 is determined, and then as the second movable rod of the second telescopic device 92 continues to extend, the force generated drives the second base 9 to start moving downward, so that the lower steel template 7 moves downward, and when the second limit block 91 located at the upper end of the second base 9 resists the support frame 1, the second movable rod is no longer extended, the second base 9 stops moving downward, and the position of the lower steel template 7 is determined. When the second movable rod of the second telescopic device 92 contracts, the lower steel template 7 does not move, and the upper steel template 6 starts to move downward; when the second limit rod 94 abuts against the upper steel template 6, the upper steel template 6 stops moving downward, and then as the second movable rod of the second telescopic device 92 continues to contract, the force generated drives the second base 9 to start moving upward, thereby the lower steel template 7 moves upward, and when the second limit block 91 located at the lower end of the second base 9 abuts against the support frame 1, the second movable rod no longer contracts, and the second base 9 and the lower steel plate stop moving upward.

The left steel template 4, the right steel template 5, the upper steel template 6 and the lower steel template 7 cooperate to form a steel core mold; for core molds with different inner polygon sizes, only the shape of the steel template needs to be adjusted. Each telescopic device controls the movement of two steel templates; when the telescopic device is extended outward, the steel templates move outward successively, and the steel templates are unfolded to form a steel core mold; when the telescopic device is retracted inward, the steel templates move inward successively, and the steel templates are demoulded after being retracted, and the support frame 1 can be directly extracted after demoulding.

本发明的预制空心板梁钢芯模机械脱模装置的工作方式：在预制空心板梁的地方安装好地板以及外侧模板，将本发明的装置吊装至预制空心板梁的空心位置，支撑架1的两端安装底座3，使支撑架1悬空；首先第一伸缩装置82依次水平地展开右钢模板5与左钢模板4，然后第二伸缩装置92依次竖直地展开上钢模板6与下钢模板7，展开的左钢模板4、右钢模板5、上钢模板6与下钢模板7形成钢芯模，接着往地板、外侧模板与钢芯模围成的空间浇筑混凝土，混凝土凝固后就形成空心板梁10。最后进行脱模操作，第二伸缩装置92依次收回上钢模板6与下钢模板7，上钢模板6与下钢模板7脱离混凝土，第一伸缩装置82依次收回右钢模板5与左钢模板4，右钢模板5与左钢模板4脱离混凝土，本发明的装置收缩完毕后，解决支撑架1与底座3的连接，抽出本发明的装置，在进行养护后投入下一次生产；在拆除外侧模板与地板后，就完成空心板梁10的生产。The working method of the mechanical demoulding device for the steel core mold of the prefabricated hollow slab beam of the present invention is as follows: the floor and the outer mold are installed at the place where the hollow slab beam is prefabricated, the device of the present invention is hoisted to the hollow position of the prefabricated hollow slab beam, and the base 3 is installed at both ends of the support frame 1 to make the support frame 1 suspended in the air; first, the first telescopic device 82 horizontally unfolds the right steel mold 5 and the left steel mold 4 in turn, and then the second telescopic device 92 vertically unfolds the upper steel mold 6 and the lower steel mold 7 in turn, and the unfolded left steel mold 4, right steel mold 5, upper steel mold 6 and lower steel mold 7 form a steel core mold, and then concrete is poured into the space surrounded by the floor, the outer mold and the steel core mold. After the concrete solidifies, a hollow slab beam 10 is formed. Finally, the demoulding operation is performed, the second telescopic device 92 retracts the upper steel formwork 6 and the lower steel formwork 7 in turn, and the upper steel formwork 6 and the lower steel formwork 7 are separated from the concrete, and the first telescopic device 82 retracts the right steel formwork 5 and the left steel formwork 4 in turn, and the right steel formwork 5 and the left steel formwork 4 are separated from the concrete. After the device of the present invention is retracted, the connection between the support frame 1 and the base 3 is solved, the device of the present invention is pulled out, and put into the next production after maintenance; after the outer formwork and the floor are removed, the production of the hollow slab beam 10 is completed.
本发明的预制空心板梁钢芯模机械脱模装置自动安装模板和脱模，脱模后直接抽取即可；芯模安装和拆卸十分方便，能保证结构尺寸满足设计要求，周转效率高，定位简单准确不偏移，不上浮，刚度大，结构安全，可多次使用。对于板梁预制数量大时，可以大量降低使用成本，具有较好的经济效益，通用性较强，对于不同内多边形尺寸的芯模只需调整钢模板就可以使用，可以避免芯模偏移和和上浮造成质量缺陷，保证成型尺寸准确，保证顶板厚度均匀。通过液压方式脱模，能保证混凝土面完整，施工步骤严谨，施工方便，可以有效控制空心板梁腔体的成型质量。The mechanical demoulding device for the prefabricated hollow slab beam steel core mold of the present invention automatically installs the template and demoulds, and can be directly extracted after demoulding; the core mold is very convenient to install and disassemble, can ensure that the structural dimensions meet the design requirements, has high turnover efficiency, simple and accurate positioning without offset or floating, high rigidity, safe structure, and can be used multiple times. When the number of prefabricated slab beams is large, the use cost can be greatly reduced, it has good economic benefits, and has strong versatility. For core molds with different inner polygon sizes, it only needs to adjust the steel template to use it, which can avoid quality defects caused by core mold offset and floating, ensure accurate molding dimensions, and ensure uniform thickness of the top plate. Demolding by hydraulic means can ensure the integrity of the concrete surface, rigorous construction steps, convenient construction, and can effectively control the molding quality of the hollow slab beam cavity.
