步骤S6，通过栓钉3或牛腿4连接梁2与预制柱1。In step S6, the beam 2 and the prefabricated column 1 are connected by the bolt 3 or the corbel 4.
其中，步骤S1-S3为预制柱上柱和预制柱下柱的浇筑生产过程，步骤S4为预制柱1的装配连接过程，步骤S5-S6为预制柱1与梁2的装配连接过程。Wherein, steps S1-S3 are the pouring production process of the prefabricated column upper column and the prefabricated column lower column, step S4 is the assembly and connection process of the prefabricated column 1, and steps S5-S6 are the assembly and connection process of the prefabricated column 1 and the beam 2.
需要对步骤S1进行说明的是，纵筋11沿预制柱1的轴线方向设置， 纵筋11的数量和分布影响预制柱1的强度；螺旋箍筋12套设于纵筋11外，螺旋箍筋12可对纵筋11进行固定并承受剪切应力，因此螺旋箍筋12的种类和尺寸会影响预制柱的抗剪强度。It should be noted that step S1 is that the longitudinal bars 11 are arranged along the axis direction of the prefabricated column 1, and the number and distribution of the longitudinal bars 11 affect the strength of the prefabricated column 1; the spiral stirrups 12 are sleeved outside the longitudinal bars 11, and the spiral stirrups 12 can fix the longitudinal reinforcement 11 and bear shear stress, so the type and size of the spiral stirrup 12 will affect the shear strength of the prefabricated column.
纵筋11主要包括普通热轧钢筋、高强钢筋、钢绞线、钢丝束、高强钢棒或纤维筋等，螺旋箍筋12主要包括为普通钢筋、高强钢筋、钢丝绳、钢丝束、钢绞线或FRP纤维等，纵筋11的种类、尺寸、数量和分布情况以及螺旋箍筋12的种类和尺寸等根据预制柱1的设计要求参考现有技术确定，在此不再赘述。The longitudinal bars 11 mainly include ordinary hot-rolled steel bars, high-strength steel bars, steel strands, wire bundles, high-strength steel bars or fiber bars, etc. The spiral stirrups 12 mainly include ordinary steel bars, high-strength steel bars, steel wire ropes, steel wire bundles, steel strands or FRP fibers, etc., the type, size, quantity and distribution of the longitudinal bars 11 and the type and size of the spiral stirrups 12 are determined according to the design requirements of the prefabricated column 1 with reference to the prior art, and will not be repeated here.

需要对步骤S2进行说明的是，箍板13环绕设置于预制柱1的外周，箍板13的形状和尺寸根据预制柱1的截面形状和尺寸确定。由于预制柱1的截面多为矩形，箍板13一般由四块钢板首尾焊接连接而成或钢板弯折后焊接而成。若预制柱的截面为圆形，箍板13通常设置为圆钢管。It should be explained in step S2 that the hoop plate 13 is arranged around the outer periphery of the prefabricated column 1 , and the shape and size of the hoop plate 13 are determined according to the cross-sectional shape and size of the prefabricated column 1 . Since the cross section of the prefabricated column 1 is mostly rectangular, the hoop plate 13 is generally formed by welding four steel plates end to end or by bending and welding the steel plates. If the cross section of the prefabricated column is circular, the hoop plate 13 is usually set as a round steel pipe.
请参考图1-图7，箍板13的内侧面一般设有栓钉3，以增强箍板13与预制柱1的连接强度，优选的，可以设置栓钉3沿预制柱1的轴线方向均匀分布。Please refer to FIG. 1 to FIG. 7 , the inner side of the hoop plate 13 is generally provided with pegs 3 to enhance the connection strength between the hoop plate 13 and the prefabricated column 1 . Preferably, the pegs 3 can be set evenly along the axis direction of the prefabricated column 1 distributed.
为了增强箍板13与预制柱1的连接强度，箍板13内焊接有环向加强板14。环向加强板14可以焊接于箍板13的端面处，如图1所示，也可以焊接于箍板13的中段，如图4所示，环向加强板14与箍板13的具体焊接位置根据实际施工过程中预制柱1的设计尺寸等因素确定。In order to enhance the connection strength between the hoop plate 13 and the prefabricated column 1 , the hoop plate 13 is welded with a circumferential reinforcing plate 14 . The circumferential reinforcing plate 14 can be welded to the end face of the hoop plate 13, as shown in FIG. 1, or can be welded to the middle section of the hoop plate 13, as shown in FIG. 4, the specific welding position of the circumferential reinforcing plate 14 and the hoop plate 13 It is determined according to factors such as the design size of the prefabricated column 1 in the actual construction process.
箍板13内焊接的环向加强板14的数量可以为一个，可以为两个，也可以为多个，其具体数量根据预制柱1的设计需求确定。The number of circumferential reinforcing plates 14 welded in the hoop plate 13 may be one, two, or more, and the specific number is determined according to the design requirements of the prefabricated column 1 .
优选的，为进一步增强节点的刚度和强度，箍板13内设有若干个竖向加劲肋。Preferably, in order to further enhance the stiffness and strength of the nodes, several vertical stiffening ribs are provided in the hoop plate 13 .
此外，环向加强板14也可以替换为设置于箍板13相对的两侧面之间的对拉锚筋16，如图9所示。当然，对拉锚筋16也可与环向加强板14同时设置。In addition, the hoop reinforcing plate 14 can also be replaced with a pair of anchor bars 16 disposed between two opposite sides of the hoop plate 13 , as shown in FIG. 9 . Of course, the anchor rib 16 may also be provided at the same time as the circumferential reinforcing plate 14 .
距预制柱1的连接处最近的环向加强板14又可称为端板，当预制柱上 柱的端板与预制柱下柱的端板之间距离较大时，请参考图4，可以在预制柱上柱的箍板13上预留灌浆口，在箍板13焊接完成后，通过灌浆口在两块端板之间进行压力灌浆混凝土。The hoop reinforcement plate 14 closest to the connection of the prefabricated column 1 can also be called the end plate. When the distance between the end plate of the upper column of the prefabricated column and the end plate of the lower column of the prefabricated column is large, please refer to Fig. A grouting opening is reserved on the hoop plate 13 of the upper column of the prefabricated column, and after the welding of the hoop plate 13 is completed, pressure grouting concrete is performed between the two end plates through the grouting opening.
需要对步骤S3进行说明的是，按照预制柱1的设计尺寸在钢筋笼和箍板13组成的钢筋骨架外支模，模具一般为预制好的钢模或铝膜，进行混凝土浇筑，分别浇筑成型预制柱上柱和预制柱下柱，浇筑可在合模后内部通过空心管道浇筑或浇筑后合模，然后通过离心法制造并养护。离心法能够增强预制柱1内混凝土的密实性，从而增加预制柱1的强度。What needs to be explained in step S3 is that according to the design size of the prefabricated column 1, the steel cage and the hoop plate 13 are formed to support the outer mold of the steel skeleton, and the mold is generally a prefabricated steel mold or aluminum film. The prefabricated column upper column and the prefabricated column lower column can be poured through the hollow pipe inside after the mold is closed or the mold is closed after pouring, and then manufactured and cured by the centrifugal method. The centrifugal method can enhance the compactness of the concrete in the prefabricated column 1 , thereby increasing the strength of the prefabricated column 1 .
浇筑所用的混凝土可以选择普通混凝土，也可以选择C60或C80等高强混凝土，其具体种类按照预制柱1的设计要求参考现有技术确定，在此不再赘述。The concrete used for pouring can be ordinary concrete or high-strength concrete such as C60 or C80. The specific type is determined according to the design requirements of the prefabricated column 1 with reference to the prior art, and details are not repeated here.
