钢筋混凝土柱作为一种重要的竖向构件，主要承担轴力、弯矩或剪力，以及其中的任意组合。在进行钢筋混凝土柱的截面设计时，柱子的抗剪与抗压是通过柱子的箍筋与混凝土本身来共同承担；柱子的抗拉主要由柱子的纵向钢筋来承担；柱子的抗弯与抗扭是通过纵向钢筋与混凝土的抗压来共同承担。其中，柱子的剪切破坏与扭转破坏面都是呈斜截面状态。 As an important vertical component, reinforced concrete column mainly bears axial force, bending moment or shear force, and any combination thereof. When designing the section of a reinforced concrete column, the shear and compression resistance of the column is jointly borne by the stirrups of the column and the concrete itself; the tensile resistance of the column is mainly borne by the longitudinal reinforcement of the column; the bending and torsional resistance of the column It is jointly borne by the compression resistance of longitudinal steel bars and concrete. Among them, the shear failure and torsional failure surfaces of the column are both in the oblique section state.
本发明正是根据上述现状和柱子的受力特点，所设计出的由钢筋混凝土预制拼装块组装而成一定高度的拼装柱。其中，钢筋混凝土预制拼装块内部配置有纵向构造钢筋，避免预制拼装块在运输安装的过程中出现破坏。预制拼装块中的横向受力箍筋根据拼装柱所需要承担的剪力进行确定，在预制工厂预制时进行配置。实际上，对于同一栋在建的建筑物而言，柱子的箍筋配置结合相关的抗震构造要求可以进行归类，减少预制拼装块的品种。拼装柱所需要的纵向受力钢筋，可以在施工现场将其穿过预制拼装块的内部孔洞，然后通过压力灌注高强浆料加强两者之间的粘结，最终成为设计所需要的竖向承重构件。 The present invention is just based on the above-mentioned present situation and the stress characteristics of the column, and the designed assembled column is assembled into a certain height by reinforced concrete prefabricated assembled blocks. Among them, the reinforced concrete prefabricated assembly block is equipped with longitudinal structural steel bars inside to avoid damage to the prefabricated assembly block during transportation and installation. The transverse stress stirrups in the prefabricated assembly block are determined according to the shear force that the assembled column needs to bear, and are configured during prefabrication in the prefabricated factory. In fact, for the same building under construction, the stirrup configuration of the columns can be classified in combination with the relevant seismic structural requirements, reducing the variety of prefabricated blocks. The longitudinally stressed steel bars required by the assembled columns can be passed through the internal holes of the prefabricated assembled blocks at the construction site, and then the high-strength slurry is injected through pressure to strengthen the bond between the two, and finally become the vertical load-bearing required by the design member.
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。 The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the description of the present invention and the contents of the accompanying drawings, or directly or indirectly used in other related technical fields, are all the same. The theory is included in the patent protection scope of the present invention.
