Description

Technical Field

[0001] The utility model belongs to the technical field of elevator equipment, and particularly relates to a column structure and an elevator shaft frame. Background Art

[0002] At present, some old residential communities or factories were not designed with elevators due to their age, which makes it inconvenient for people to go up and down the stairs and carry goods. Since the design of old residential communities or factories in the past did not consider reserving elevator installation shafts, the installation of elevators has gradually become a demand. By designing a separate elevator on the outside of the building wall, it can meet the travel needs of the elderly and also facilitate the handling of goods. When installing an elevator, the steel structure required in the elevator shaft includes columns, beams, and bolted connectors. Depending on the height of the elevator shaft, column support structures of different heights need to be built.

[0003] Most of the columns of existing elevator shafts are rectangular column tubes, and the columns and beams are fixed by welding or bolt connectors. For example, Chinese patent document CN208790978U discloses an elevator shaft steel frame structure, which is mainly intended to provide a new type of elevator shaft steel frame structure to effectively improve the installation efficiency of shaft installation operations on the outside of buildings. The elevator shaft steel frame structure includes a plurality of vertical longitudinal beams arranged from the ground upward, connecting beams are distributed between the vertical longitudinal beams, and longitudinal transition splicing blocks are arranged between the vertical longitudinal beams arranged adjacent to each other from bottom to top. Both ends of the connecting beams arranged between the vertical longitudinal beams arranged adjacent to each other on the left and right are connected to the vertical longitudinal beams through transverse transition splicing blocks, and shock-absorbing bases are provided at the bottom of the vertical longitudinal beams arranged at the lowest end. The elevator shaft steel frame structure effectively reduces the high-altitude operation welding process of the elevator shaft steel frame structure, effectively improves the seismic performance of the steel frame shaft outside the building, and improves the installation quality stability performance of the shaft installed outside the building.

[0004] The columns in the elevator shaft steel frame structure of the above-mentioned patent document are rectangular column tubes. To ensure strength, the column tubes need to maintain a certain wall thickness. This method will result in a larger overall mass of the elevator shaft, increase the difficulty of transportation and installation, and increase production costs. If the wall thickness of the column tube is to be reduced, such as using "cold-bent thin-walled square tubes" as column tubes, it is necessary to install reinforcement plates inside the column tubes to increase the strength of the connection nodes between the column tubes and the crossbeams. However, it is difficult to install reinforcement plates inside the column tubes with the existing technology. Therefore, it is necessary to provide a column structure and an elevator shaft frame to solve the problems existing in the existing technology. Utility Model Content

[0007] As an optional implementation of the above technical solution, the outer dimensions of the reinforcing plate match the inner dimensions of the tubular column, and a notch is provided on the side wall of the reinforcing plate.

[0012] As an optional implementation of the above technical solution, each side wall of the square tube is provided with two welding slots.

[0024] like Figure 1 As shown, this embodiment provides a column structure, including a tubular column 1, wherein a plurality of welding slots 2 are opened on the circumference of the tubular column 1, and the welding slots 2 are connected to the interior of the tubular column 1. The specific number of the welding slots 2 can be set according to actual needs.

[0025] like Figure 4 As shown, a reinforcing plate 3 is provided inside the tubular column 1. The position of the reinforcing plate 3 corresponds to the position of the welding slot 2. The reinforcing plate 3 is welded to the tubular column 1 through the welding slot 2. After the reinforcing plate 3 is transported into the tubular column 1, the side wall of the reinforcing plate 3 is aligned with the welding slot 2, and then the welding slot 2 is fully welded to achieve the fixation of the reinforcing plate 3 to the tubular column 1.

[0026] like Figure 2 As shown, in this embodiment, the outer dimensions of the reinforcing plate 3 match the inner dimensions of the tubular column 1, and a notch 4 is formed in the sidewall of the reinforcing plate 3. The notch 4 is U-shaped, which facilitates the movement of the reinforcing plate 3 into the tubular column 1 to the position of the welding slot 2.

[0027] In order to facilitate the transportation of the reinforcing plate 3 into the interior of the tubular column 1, the reinforcing plate 3 is provided with a guide member, which is used to guide the reinforcing plate 3 into the interior of the tubular column 1. Figure 3 As shown, specifically, the guide member includes a guide rod 5, one end of which is provided with a connector 6, which is detachably connected to the reinforcement plate 3. After the connector 6 is connected to the reinforcement plate 3, the reinforcement plate 3 is moved into the tubular column 1 using the guide rod 5. After the reinforcement plate 3 is welded, the connector 6 is separated from the reinforcement plate 3 and the guide rod 5 is removed so that the reinforcement plate 3 can be fixed again.

[0028] The connector 6 and the reinforcement plate 3 can be connected in a variety of ways, such as by snap-fitting or magnetic connection. In one embodiment, the connector 6 is provided with external threads, and the reinforcement plate 3 is provided with a mounting hole 7. The inner wall of the mounting hole 7 is provided with internal threads that mate with the external threads. The connector 6 is threadedly connected to the reinforcement plate 3, facilitating assembly and disassembly of the reinforcement plate 3.

[0029] like Figure 1 As shown, in one embodiment, the tubular column 1 is a square tube, and each of the four side walls of the square tube is provided with welding slots 2, with the welding slots 2 on opposite sides of the square tube being flush. The welding slots 2 on the four side walls of the square tube are located at the same height, and the reinforcing plate 3 and the tubular column 1 have multiple welding points, increasing the weld seams and significantly improving the connection strength between the reinforcing plate 3 and the tubular column 1. Preferably, each side wall of the square tube has two welding slots 2.

[0030] like Figure 5 As shown, when welding the reinforcing plate 3, first thread the connecting head 6 to the reinforcing plate 3, and then transport the reinforcing plate 3 to the inside of the tubular column 1 to the position of the welding slot 2 through the guide rod 5. At this time, a temporary thin sheet can be used to pass through the two welding slots 2 on the opposite side walls of the square tube. The temporary thin sheet is used to position the reinforcing plate 3, which can increase the positioning accuracy of the reinforcing plate 3 and the welding slot 2. After the reinforcing plate 3 is fixed by spot welding, the temporary thin sheet is pulled out, and the guide rod 5 is reversed to separate the connecting head 6 from the reinforcing plate 3, and then the welding slot 2 is fully welded to achieve the fixation of the reinforcing plate 3 and the tubular column 1.

[0031] The utility model can use a cold-bent thin-walled square tube as the tubular column 1, and can smoothly weld the reinforcing plate 3 inside the tubular column 1, thereby increasing the strength of the connection node between the tubular column 1 and the crossbeam 8. On the basis of ensuring the strength of the elevator shaft frame structure, the overall mass of the column structure is reduced, the transportation and installation difficulty of the elevator shaft is reduced, and the production cost is reduced.

[0032] This embodiment also provides an elevator shaft frame, including the above-mentioned column structure, wherein the elevator shaft frame has four vertically arranged column structures and at least four horizontally arranged crossbeams 8, and adjacent column structures are connected by the crossbeams 8. The four column structures are arranged at the four vertices of a virtual rectangle, and the crossbeams 8 are connected to the tubular column 1 to form a rectangular elevator shaft frame. Four crossbeams 8 are arranged as a group. For some higher shafts, multiple groups of crossbeams 8 can be provided to ensure the structural stability of the elevator shaft frame.

[0033] like Figure 4 As shown, the fixed position of the reinforcing plate 3 inside the tubular column 1 corresponds to the fixed position of the cross beam 8 outside the tubular column 1, so as to enhance the strength of the connection node between the tubular column 1 and the cross beam 8. The cross beam 8 is arranged outside the tubular column 1, and the reinforcing plate 3 is arranged inside the tubular column 1, and the reinforcing plate 3 is used to enhance the strength of the connection node between the tubular column 1 and the cross beam 8.

[0034] In one embodiment, the crossbeam 8 is a rectangular hollow structure, and the ends of the crossbeam 8 are fixed to the tubular column 1 by welding. The surface of the tubular column 1 fits the end of the crossbeam 8, and the tubular column 1 seals the end of the crossbeam 8 to prevent rainwater from entering the interior of the crossbeam 8 and causing corrosion.

[0035] In order to further improve the strength of the connection node between the tubular column 1 and the crossbeam 8, two reinforcing plates 3 are provided inside the tubular column 1, and the two reinforcing plates 3 are flush with the top and bottom of the crossbeam 8 respectively.

[0036] The utility model can weld the reinforcing plate 3 inside the tubular column 1 in advance, and only the tubular column 1 and the crossbeam 8 need to be welded together on site. It can effectively improve the installation efficiency of the elevator shaft, while reducing the installation and construction costs of the enterprise, and effectively improve the economic benefits of the enterprise.
