作为优选的，本实用新型中步骤(5)中在灌入口上增设用于密封的钢片10，在两个单体预制柱拼接时，将预制的与灌入孔9等大的钢片10填入灌入孔9中，实现灌入孔9的密封，通过钢片10的设置，保证混凝土处于内部，避免混凝土外露，同时也方便混凝土快速凝结。As preferably, in step (5) in the utility model, the steel sheet 10 that is used for sealing is added on pouring inlet, when two monomer prefabricated columns are spliced, the steel sheet 10 that is prefabricated and pours into hole 9 equal big Fill in the pouring hole 9 to realize the sealing of the pouring hole 9. Through the setting of the steel sheet 10, it is ensured that the concrete is inside to avoid the concrete from being exposed, and it is also convenient for the rapid setting of the concrete.
本实用新型中单体预制柱的制备工艺：①在工厂进行制作前对进场束形钢管1柱经进行技术资料检查，并对束形钢管外观和几何尺寸进行检查，符合要求后才能使用；②束形钢管1要做防护措施，防止泥浆异物污染钢管壁；③将制备好的钢筋3通过加配箍筋形成钢筋束4，再把钢筋束4放入束形钢管1中；④在钢筋束4放入束形钢管1中对束形钢管1进行清理；⑤清理完毕后，在束形钢管1内灌入制型混凝土2；⑥检查钢筋束4的垂直度，如发现有偏差应马上人工调整，调整完毕后，静置，使得制型混凝土2凝结成型即可。通过以上操作可以制成单体预制柱。The preparation process of the single prefabricated column in the utility model: ① before the production in the factory, check the technical data of the beam-shaped steel tube 1 column that enters the site, and check the appearance and geometric dimensions of the beam-shaped steel tube, and it can be used only after meeting the requirements; ②Bundle-shaped steel pipe 1 should take protective measures to prevent mud and foreign matter from contaminating the steel pipe wall; ③The prepared steel bar 3 is formed by adding stirrups to form a reinforcement bundle 4, and then the reinforcement bundle 4 is put into the bundle-shaped steel pipe 1; ④In the reinforcement bundle 4 Put it into the beam-shaped steel pipe 1 to clean the beam-shaped steel pipe 1; ⑤ After cleaning, pour the molded concrete 2 into the beam-shaped steel pipe 1; Adjustment, after the adjustment is completed, let it stand still so that the molded concrete 2 can be condensed and formed. Monolithic prefabricated columns can be made through the above operations.
本实用新型中装配式钢管约束混凝土柱的生产工艺：①选取需要拼接的两个单体预制柱，将预制好的拼接钢管6安放在两个单体预制柱之间；②将一个需要连接的单体预制柱与另一个需要连接的单体预制柱中的钢筋3进行对接，对接完成后，用套筒将各个相互对应钢筋3连接起来；③将拼接钢管6分别与两个单体预制柱中的束形钢管1进行焊接；④通过拼接钢管6上的灌入孔9，将固定混凝土8从灌入孔9中灌入拼接钢管6；⑤将预制的与灌入孔9等大的钢片10填入灌入孔9中密封；待固定混凝土8成型，装配结束。The production process of the assembled steel pipe-constrained concrete column in the utility model: ① select two single prefabricated columns that need to be spliced, and place the prefabricated spliced steel pipe 6 between the two single prefabricated columns; The single prefabricated column is docked with the reinforcement 3 in another single prefabricated column that needs to be connected. After the docking is completed, each corresponding steel bar 3 is connected with a sleeve; The beam-shaped steel pipe 1 in the steel pipe 1 is welded; ④ through the pouring hole 9 on the splicing steel pipe 6, the fixed concrete 8 is poured into the splicing steel pipe 6 from the pouring hole 9; The sheet 10 is filled into the pouring hole 9 and sealed; the fixed concrete 8 is formed, and the assembly is completed.
同时在本实用新型中不管是制型混凝土2和固定混凝土8，这里只是起到的作用不同，从而命名不同，实际材料应用基本相同，也是常有材料，这里不再赘述。Simultaneously in the utility model, no matter it is the shaped concrete 2 and the fixed concrete 8, here they just play different roles, thus the names are different, and the actual material applications are basically the same, and there are also common materials, which will not be repeated here.
显然本实用新型具体实现并不受上述方式的限制，只要采用了本实用新型的方法构思和技术方案进行的各种非实质性的改进，均在本实用新型的保护范围之内。Apparently, the specific implementation of the utility model is not limited by the above methods, as long as various insubstantial improvements are made by adopting the method concepts and technical solutions of the utility model, they all fall within the protection scope of the utility model.
