Description

Technical Field

[0002] In order to meet the production needs of modern new industries, more and more factories are built as steel-structured multi-intermediate column factories. The factory building includes both superstructures such as frame columns and ground structures such as structural foundations. For example, a Chinese patent document with application number CN2024108831079 discloses such a ground structure for a multi-intermediate column factory building, which mainly improves the ground layer between each column base, so that the flatness, integrity, strength, and impact toughness of the factory floor are enhanced to a certain extent. The structural foundation such as the column base is consistent with the traditional structure.

[0003] Generally, shear grooves are set on the column base, and shear keys are set at the bottom of the middle column. The shear keys are embedded in the column base, and the shear force acting on the middle column can be transmitted to the foundation through the vertical surface of the shear key and the lateral pressure of the column base. Although this passive shear resistance structure can also resist the horizontal shear force of the middle column foot, there is still room for improvement in maintaining the stability and safety of the middle column structure.

[0012] As an embodiment, the transverse support member and the longitudinal support member have the same shape.

[0013] As an embodiment, the groove plate includes side plates and a bottom plate, the side plates are arranged at four places on the side walls of the shear groove, the bottom plate is arranged at one place at the bottom of the shear groove, and the side plates are connected to the bottom plate.

[0014] As an implementation manner, the adjustment components at the bottom of each of the transverse support plates or the bottom of the longitudinal support plates are provided at two locations.

The adjustment component in the opposite direction will resist the tendency of the middle column to tilt due to the slight shortening in length. Compared with the traditional coordination of shear grooves and shear keys, the ground structure used for factories with multiple middle columns, by filling the adjustment component between the shear keys and the groove plates, makes it work in conjunction with the horizontal support plates or the vertical support plates, thereby generating an active force to resist tilting. This can resist the horizontal shear force at the foot of the middle column and maintain the stability and safety of the middle column structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, the ground structure for the factory building with multiple intermediate columns, as the structural foundation of a modern factory building, has a number of column bases 1 evenly distributed in the longitudinal and transverse directions. The longitudinal and transverse directions refer to two directions perpendicular to each other, and the longitudinal and transverse directions are both horizontal directions. According to the general design requirements of the factory building, the column bases 1 in the longitudinal direction are evenly distributed, and the column bases 1 in the transverse direction are also evenly distributed, wherein the longitudinal spacing and the transverse spacing may be the same or different. The layer structure 2 filled between the column bases 1 is not specifically expanded in this embodiment. The layer structure 2 may preferably be a new layer structure on the market, so that the flatness, integrity, strength, and impact toughness of the factory floor are enhanced to a certain extent.

[0031] In this embodiment, the improvement of the ground structure for the multi-intermediate column factory building lies in the column base 1. Like the traditional column base, a sunken shear groove 3 is opened on the surface of the column base 1. The difference is that a metal groove plate 4 is arranged in the shear groove 3, which has a harder texture than cement metal. The groove plate 4 provides a rigid support for the telescopic movement of the scissor arm 19. Figure 3 and Figure 7 As shown, the surface of the column base 1 is provided with a transverse rotating seat 5 and a longitudinal rotating seat 6 arranged along two opposite edges of the shear groove 3, and the two transverse rotating seats 5 are rotatably connected with a V-shaped transverse support member 7, and a transverse support plate 8 is arranged between the two transverse support members 7. The transverse support member 7 can rotate around the rotation axis on the transverse rotating seat 5, and during the rotation process, one side of the transverse support plate 8 can be raised and the other side of the transverse support plate 8 can be lowered. Figure 3 and Figure 8 As shown, the surface of the column base 1 is provided with a transverse swivel seat 5 and a longitudinal swivel seat 6 arranged along the two opposite edges of the shear groove 3, and the two longitudinal swivel seats 6 are rotatably connected with V-shaped longitudinal struts 9, and a longitudinal strut plate 10 is provided between the two longitudinal struts 9. The longitudinal strut 9 can rotate around the rotating axis on the longitudinal swivel seat 6, and can raise one side of the longitudinal strut plate 10 and lower the other side of the longitudinal strut plate 10 during the rotation process. The surfaces of the two transverse strut plates 8 and the surfaces of the two longitudinal strut plates 10 are both attached to the bottom of the middle column 11 to provide real-time feedback on the position status of the bottom of the middle column 11. If the middle column 11 tends to tilt in the four directions of transverse and longitudinal, it will be immediately received by the transverse strut plate 8 or the longitudinal strut plate 10.

[0032] like Figure 3 and Figure 4 As shown, the square through hole 12 formed by the two transverse support plates 8 and the two longitudinal support plates 10 is for the shear key 13 arranged at the bottom of the middle column 11 to pass through, the transverse support plate 8 is provided with two transverse clearance openings 14 respectively close to the two ends and open inward, the longitudinal support plate 10 is provided with two longitudinal clearance openings 15 respectively located outside the two ends, the two ends of the transverse support plate 8 are embedded in the longitudinal clearance openings 15 and a first gap 16 is provided between the two ends, and the two ends of the longitudinal support plate 10 are embedded in the transverse clearance openings 14 and a second gap 17 is provided between the two ends. Therefore, when the transverse support plate 8 rotates slightly, the longitudinal support plate 10 does not affect it, and when the longitudinal support plate 10 rotates slightly, the transverse support plate 8 does not affect it, and at the same time, a square through hole 12 for the shear key 13 to pass through can be formed.

[0033] like Figure 3 , Figure 7 and Figure 8As shown. An adjustment assembly 18 is provided in the shear groove 3 at the bottom of each transverse support plate 8 and the bottom of each longitudinal support plate 10, and each is provided at two locations. The adjustment assembly 18 includes a plurality of scissor arms 19 connected end to end, one end of the scissor arm 19 at the top is rotatably connected to the bottom of the transverse support plate 8 or the bottom of the longitudinal support plate 10, one end of the scissor arm 19 at the bottom is rotatably connected to the groove plate 4, the ends of the plurality of scissor arms 19 facing the groove plate 4 are in conflict with the groove plate 4, and the ends of the plurality of scissor arms 19 facing the shear key 13 are in conflict with the shear key 13 and protrude in the vertical direction relative to the edge of the square through hole 12. Therefore, if the middle column 11 has a tendency to tilt in the four directions of the horizontal and vertical directions, the adjustment component 18 located in the direction can be compressed and slightly stretched, thereby raising the horizontal support plate 8 or the longitudinal support plate 10 connected to it, and lowering the horizontal support plate 8 or the longitudinal support plate 10 connected to the adjustment component 18 in the opposite direction. Then, the adjustment component 18 in the opposite direction resists the tendency of the middle column 11 to tilt due to the slight shortening in length. Compared with the cooperation of the traditional shear groove 3 and the shear key 13, in this embodiment, by filling the adjustment component 18 between the shear key 13 and the groove plate 4, it is linked with the horizontal support plate 8 or the longitudinal support plate 10, thereby generating an active force to resist the tilt. In order to resist the horizontal shear force of the middle column foot, the stability and safety of the middle column structure are maintained.

That is, the spacing between the two transverse swivel seats 5 is equal to the spacing between the two longitudinal swivel seats 6. In this way, the transverse support member 7 and the longitudinal support member 9 can be of the same shape. The transverse support member 7 is arranged on the outside of the transverse swivel seat 5, and the longitudinal support member 9 is arranged on the inside of the longitudinal swivel seat 6, thereby forming a staggered installation. The transverse support member 7 is V-shaped, and its two ends are respectively connected to the ends of the two transverse support plates 8, and the transverse support plates 8 are supported from both ends.
