[0002] In recent decades, steel structures have been used more and more widely. The column base nodes in steel structures, as important stress-bearing parts in the rigid structure system, are not only directly related to the reliability of the entire structure, but also affect the construction quality, project progress and cost of the entire project.

[0003] Column foot nodes are generally divided into three types: exposed, external and embedded.

However, as the steel structure system becomes increasingly complicated, higher requirements are put forward for the bending, tension, compression and punching resistance of embedded column foot nodes.

[0053] The technical solution of the present application will be described in detail below with reference to the accompanying drawings and in combination with the implementation modes.

[0054] In the first aspect, the present application provides an embedded column foot node. The column foot node can be understood as a connection node at the bottom of a building structure column. It is an important connection point between the column and the foundation. Its main function is to effectively transfer the internal forces of the column body, such as pressure, bending moment, shear force, and tension, to the foundation and ensure that the steel column can remain stable when subjected to external forces.

[0055] like Figure 1-2 As shown, the embedded column base node provided in the present application includes: a column body 1, a transverse partition 2, an anchor bolt 3, at least two vertical partitions 4, a transverse rib plate 6 and a bottom plate 7.

[0056] The middle of the column 1 vertically passes through the center of the diaphragm 2 and is welded to the diaphragm 2, so that the diaphragm 2 and the column 1 form a mutually perpendicular structure. When the axial pressure of the column 1 is transmitted, the diaphragm 2 can serve as an anti-shearing component, so that the shearing area of ​​the building structure foundation on both sides is expanded and moved upward, thereby achieving the purpose of reducing the embedded depth.

[0057] In a specific embodiment, the diaphragm 2 and the column 1 are welded at 1 / 2 of the height of the column to make the overall structure of the diaphragm 2 and the column 1 more stable. The shape of the column 1 can be box-shaped, circular, H-shaped or other shapes, preferably box-shaped, including four column corners.

[0058] One end of the anchor bolt 3 passes through the diaphragm 2, and the other end extends downward and is buried in the foundation of the building structure, so that the anchor bolt 3 and the diaphragm 2 constitute the resistance to the tension of the column foot node, that is, for the tension of the column foot, the anchor bolt 3 and the diaphragm 2 are arranged in the middle of the column foot to directly resist the tension together.

[0059] First, in the present application, a transverse partition 2 is added in the middle of the column 1, and an anchor 3 whose lower part is pre-buried in the foundation of the building structure is set downward in the transverse partition 2, so that the head position of the anchor 3 corresponds to the middle of the column 1. Compared with the traditional method of directly setting the anchor at the bottom of the column, the anchor 3 in the present application is moved up to 0.5 times the depth of the column foot, so that the present application does not need to increase the anchor burial space additionally, and the burial of the anchor 3 can be completely solved within the depth of the column foot, and the burial depth of the column foot node will not be increased additionally.

[0060] Second, the anchor bolt 3 is used as a construction and installation positioning piece for the column foot. The anchor bolt 3 is first buried and positioned at a position close to the ground surface, which is conducive to the assembly construction of the column foot and makes the installation and fixation of the column foot more accurate. More importantly, the setting method of the anchor bolt 3 in this application can achieve the above-mentioned effects while not affecting the reasonable force transmission path of the column foot to resist bending moment and shear force, so that the overall structure can reduce the pre-embedded depth and maintain structural stability.

[0061] Third, the support reaction force of the compression zone of the building structure foundation on the side of the column foot forms a resistance force, which is balanced with the bending moment and shear force of the column 1. The bending moment and shear force of the column foot are not borne by the anchor bolt 3, so the anchor bolt 3 and the diaphragm 2 are set in the middle of the column 1 (at 1 / 2 of the height) to avoid the anchor bolt 3 from participating in the resistance force as much as possible, reduce interference, and make the force transmission path clearer. When the upward pull force of the column 1 is transmitted, the diaphragm 2 and the anchor bolt 3 together form an anti-pullout key to prevent the column foot from being pulled out as a whole.

[0062] In a specific embodiment, the anchor bolts 3 are provided in plurality and are evenly distributed in the diaphragm 2. The anchor bolts 3 are vertically embedded in the foundation of the building structure and vertically penetrate the diaphragm 2, and are arranged parallel to the column 1 as a whole. Moreover, the embedded length of the anchor bolts 3 does not exceed the bottom of the column 1.

[0063] The vertical partition 4 is vertically welded to the outer surface of the column 1, so that the vertical partition 4 and the column 1 form a balanced force of bending moment and shear force at the column foot node. For the bending and shearing of the column foot, according to the embedded column foot design theory, the pressure is transmitted from the side of the column foot. The present application increases the width of the column foot by adding a vertical partition 4 to the side of the column 1, thereby increasing the area of ​​the concrete compression zone on the side of the column foot, so that the column foot as a whole can resist greater bending moment and shear force, thereby reducing the embedded depth of the column foot. At the same time, according to the support reaction force of the side compression zone composed of the column 1 and the vertical partition 4, a resistance is formed, which is balanced with the bending moment and shear force of the steel column 1, and the embedded depth of the column foot can be obtained.

[0064] In a specific embodiment, the vertical partitions 4 are disposed on the outer surface of the column 1. When the column 1 is box-shaped, the column 1 includes four column corners, and there are eight vertical partitions 4, which are respectively disposed on the right angle side of each column corner of the column 1.

[0065] To ensure the overall structural stability of the column foot node, in some embodiments, the bottom of the vertical partition 4 is directly vertically welded to the transverse partition 2. In other preferred embodiments, the column foot node in the present application further includes a first vertical rib 51, and the vertical partition 4 is connected to the transverse partition 2 through the first vertical rib 51.

[0066] The shape of the first vertical rib 51 is set to be a trapezoidal shape with one connecting end having a length greater than the other connecting end and a vertical shape on the other side, and the longer end is welded to the plane of the transverse partition 2. The first vertical rib 51 has a trapezoidal shape with a slope, which is conducive to transmitting force to the transverse partition 2. The first vertical rib 51 is set at a position corresponding to the position directly below the vertical partition 4, and its vertical side surface is welded to the outer surface of the column 1. The longer end is vertically welded to the plane of the transverse partition 2, and the shorter end is welded to the vertical partition 4, so as to share various forces with the vertical partition 4 in the vertical extension direction of the vertical partition 4, thereby reducing the risk of deformation of the overall structure.

[0067] In some more preferred embodiments, the column foot node in the present application further includes a second vertical rib 52. The second vertical rib 52 has the same shape as the first vertical rib 51, and the same longer end is also welded to the plane of the transverse partition 2, and its vertical side is also welded to the outer surface of the column 1. However, the second vertical rib 52 is located between the two vertical partitions 4, and the other end is not connected to other components, so as to increase the various forces borne at the middle position of the two vertical partitions 4 and reduce the risk of overall deformation.

[0068] The two ends of the transverse rib 6 are welded transversely and vertically to the two vertical partitions 4, and the side surfaces are welded vertically to the outer surface of the column 1 and are parallel to the transverse partition 2, so that the transverse rib 6, the transverse partition 2 and the anchor bolts 3 arranged under the transverse partition 2 constitute the resistance to the tensile force of the column foot node.

[0069] In a specific embodiment, the transverse rib 6 includes a first transverse rib 61 and a second transverse rib 62. The first transverse rib 61 is transversely welded to the top between the two vertical partitions 4, and its surface is flush with the top of the vertical partition 4 and the top of the column 1. The second transverse rib 62 is transversely welded to the middle between the two vertical partitions 4, and the second transverse rib 62 is arranged on the upper side of the second vertical rib 52, and the position of the second vertical rib 52 corresponds to the center of the second transverse rib 62.

[0070] In other embodiments, there are more than two transverse ribs 6, which are evenly distributed laterally between two vertical partitions 4, so that the transverse ribs 6 have the same spacing with each other, so that the pressure and tension borne by the column base node structure can be evenly distributed to each transverse rib 6, thereby improving the strength of the column base node structure.

[0071] The bottom plate 7 is welded horizontally to the bottom of the column 1. As for the compression of the column foot, since a transverse diaphragm 2 is set in the middle of the column foot, which is equivalent to an axial pressure-bearing plate, it and the bottom plate 7 share the pressure (distributed according to the area), and the transverse rib 6 can play a compressive role, which increases the overall pressure-bearing capacity of the column foot and greatly reduces the pressure that the bottom plate 7 needs to share, so that the bottom surface of the column foot will not be damaged by compression and shearing due to the thin concrete foundation, which is conducive to reducing the thickness of the concrete foundation. That is, the transverse diaphragm 2, the transverse rib 6 and the bottom plate 7 constitute the resistance to the pressure of the column foot node, greatly reducing the pressure that the bottom plate 7 needs to share, preventing the foundation under the column from being compressed and shearing, and reducing the thickness of the foundation.

[0072] At the same time, the transverse ribs 6 and the bottom plate 7 can also play a tensile role, reducing the tensile force shared by the anchor bolts 3 and optimizing the size of the anchor bolts 3.

[0073] Based on the above structure, since the transverse partition 2 in the present application is arranged in the middle part of the column 1, in order to ensure the symmetry and stability of the overall upper and lower structures of the column foot node, in a specific embodiment, in addition to the anchor bolts 3 and the base plate 7, the vertical partitions 4, vertical ribs 5 and transverse ribs 6 in the column foot node are centered on the transverse partition 2 and are respectively arranged as two sets, upper and lower.

[0074] On the upper plane of the transverse partition 2, a first set of vertical partitions 4, vertical ribs and transverse ribs 6 are arranged upward; the longer end of the first set of first vertical ribs 51 is welded to the upper plane of the transverse partition 2, and the shorter end is welded to the bottom of the first set of vertical partitions 4, and the top and middle parts between the two first sets of vertical partitions 4 are respectively provided with a first transverse rib 61 and a second transverse rib 62, and the area below the second transverse rib 62 corresponds to the second vertical rib 52 welded to the upper plane of the transverse partition 2.

[0075] On the lower plane of the transverse partition 2, a second set of vertical partitions 4, vertical ribs and transverse ribs 6 are arranged downward; the longer end of the second set of first vertical ribs 51 is welded to the lower plane of the transverse partition 2, and the shorter end is welded to the top of the second set of vertical partitions 4, a second transverse rib 62 is arranged in the middle between the two second sets of vertical partitions 4, and the bottom of the second set of vertical partitions 4 is welded to the bottom plate 7. The area above the second transverse ribs 62 corresponds to the second vertical ribs 52 welded to the lower plane of the transverse partition 2.
