Description

Technical Field

[0001] This utility model relates to elevator shaft structures, specifically to an aluminum elevator shaft structure. Background Technology

[0002] The elevator shaft is the passageway for the elevator car and counterweight. Its walls are mainly divided into concrete shafts and steel shafts. Steel shafts are often fixed to concrete shaft walls and are generally assembled into a single structure using welding or bolting. Because welded steel shafts present challenges in construction, requiring advanced welding techniques for high-altitude operations, prefabricated steel shafts are more commonly used. In prefabricated steel shafts, all components are prefabricated in a factory and then bolted together on-site and fixed to the concrete shaft wall, eliminating the need for high-altitude welding and facilitating widespread implementation. Therefore, prefabricated elevator shaft structures, primarily made of steel, are increasingly widely used. Given that aluminum alloys possess strength approaching that of high-alloy steel, superior stiffness compared to steel, and excellent casting and plastic processing properties, as well as good corrosion resistance and lightweight characteristics, aluminum alloy elevator shaft structures can replace steel shaft structures in certain applications. Existing aluminum prefabricated elevator shaft structures mostly use bolts to fix the four corners of the four columns and the crossbeams to form a square shaft frame. This generally has problems with poor stability and reliability of the connection position, as well as poor load-bearing and impact resistance. After long-term operation, it is easy to cause safety accidents, resulting in poor safety. Utility Model Content

[0003] This utility model provides an aluminum elevator shaft structure that improves the connection structure between the columns and beams in the elevator shaft, thereby improving the connection stability and reliability of the aluminum elevator shaft structure at the docking position, and enhancing its load-bearing capacity and impact resistance.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an aluminum elevator shaft structure, including four columns, multiple pairs of first crossbeams, multiple pairs of second crossbeams, multiple support members, and multiple studs. The support members and studs can have a one-to-one correspondence or a multiple-to-one correspondence. The two ends of the first crossbeams are fixedly connected between two front and rear opposite columns. The two ends of the second crossbeams are fixedly connected between two left and right opposite columns.

[0005] The column includes a first arm plate, a second arm plate, and a third arm plate connected in a U-shape, or a "gate" shape, as well as a fourth arm plate connected to the end of the second arm plate and opposite to the first arm plate.

[0006] The fourth arm plate extends towards the third arm plate, meaning the fourth arm plate is directly opposite the first arm plate. A gap is formed between the free end of the fourth arm plate and the surface of the third arm plate. A first flange plate, extending in the same direction as the fourth arm plate, is connected to the end of the third arm plate, with the flange plate extending away from the fourth arm plate. Similarly, a second flange plate, extending in the same direction as the third arm plate, is connected to the end of the fourth arm plate, with the flange plate extending away from the first arm plate.

[0007] The end of the first crossbeam is fixedly connected to the first flange plate, and the end of the second crossbeam is fixedly connected to the second flange plate by bolts.

[0008] The support member includes a body and insert plates disposed on the body. Preferably, there are multiple insert plates, and more preferably, two rows of insert plates. Each row of insert plates includes multiple insert plates arranged alternately in the vertical direction. A cylindrical through hole is formed on the body of the support member between the two rows of insert plates. Correspondingly, the third and fourth arm plates are respectively provided with insertion holes that can establish a mating relationship with the insert plates. Preferably, there are also multiple insertion holes, and they are arranged in two rows corresponding to the two rows of insert plates. Each row of insertion holes contains multiple insertion holes, and a strip-shaped hole extending vertically is formed between the two rows of insertion holes. Generally, the number of insertion holes is greater than the number of insert plates. Each insert plate on the support member can be inserted into a corresponding insertion hole.

[0009] Each support component's body corresponds to and matches the ends of the first and second crossbeams, forming a lifting support structure. After the stud passes through the cylindrical through-hole and the strip-shaped hole, and a nut is fitted at its end, the support component can be fixed to the third and fourth arm plates respectively.

[0010] Optionally, a wedge surface is formed at the root of the insert plate, on both the upper and lower end faces, such that the end of the wedge surface near the body extends in a direction away from the end face.

[0011] Optionally, multiple linear grooves or multiple protrusions are formed on the wedge surface in alternating patterns.

[0012] Optionally, both the first and second crossbeams are channel steel structures, and the body of the support is positioned in the channel of the channel steel structure and contacts the inner top surface of the channel.

[0013] Optionally, the body of the support member is U-shaped, and the vertical plate of the U-shaped body is respectively opposite to the end face of the third arm plate and the end face of the fourth arm plate.

[0014] Optionally, multiple vertically spaced cylindrical through holes are formed on the upright plate of the U-shaped body, and a stud is disposed at each cylindrical through hole.

[0015] The beneficial effects of this utility model are: This utility model improves the connection structure between the columns and beams of the elevator shaft, which significantly improves the connection stability and reliability of the aluminum elevator shaft structure at the docking position, and enhances the load-bearing capacity and impact resistance.

They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, terms such as "upper," "lower," "front," "rear," and "middle" used in this specification are merely for clarity and not intended to limit the scope of this invention.

[0025] like Figures 1 to 6 The aluminum elevator shaft structure shown includes four columns 10, multiple pairs of first crossbeams 40, multiple pairs of second crossbeams 50, multiple support members 20, and multiple studs 30. The number of support members 20 can be the same as the number of studs 30, allowing for a one-to-one correspondence. Alternatively, the number of studs 30 can be an integer multiple of the number of support members 20, and more than twice that number. In this case, the number of cylindrical through holes 211 disposed on the support members 20 can be multiple, allowing multiple studs 30 to match with the support members 20.

[0026] Referring to existing technology, the two ends of the first crossbeam 40 are fixedly connected between two opposing columns 10; the two ends of the second crossbeam 50 are fixedly connected between two opposing columns 10. The first crossbeam 40 and the second crossbeam 50 have multiple layers in the vertical direction, and the four columns 10 are fixedly connected as a whole and extend firmly in the vertical direction. The columns 10 are fixed to the concrete well wall 100 with bolts. A secondary rail support 200 is fixedly installed on the first crossbeam 40 on the left side, and a main rail support 300 is fixedly installed on the first crossbeam 40 on the right side.

[0027] The column 10 includes a first arm plate 11, a second arm plate 12, and a third arm plate 13 connected in a U-shape (or a 'door' shape), and a fourth arm plate 14 connected to the end of the second arm plate 12 and opposite to the first arm plate 11. The fourth arm plate 14 extends toward the third arm plate 13, and its free end forms a gap with the surface of the third arm plate 13. Thus, the cross-section of the column 10 is formed as a square tube (including square or rectangular) structure with a notch on one side, see [reference]. Figure 2 As shown. To increase the overall rigidity and strength of the column 10, multiple reinforcing ribs are vertically spaced inside the column 10.

[0028] like Figures 1 to 3As shown, a flange plate 15, extending in the same direction as the fourth arm plate 14, is connected to the end of the third arm plate 13, and extends away from the fourth arm plate 14. A flange plate 16, extending in the same direction as the third arm plate 13, is connected to the end of the fourth arm plate 14, and extends away from the first arm plate 11. The end of the first crossbeam 40 is fixedly connected to the flange plate 15 by bolts; the end of the second crossbeam 50 is fixedly connected to the flange plate 16 by bolts. Multiple through holes are provided vertically on the first arm plate 11 and the second arm plate 12. Bolts are installed in (partially) the through holes to fix the column 10 at the angle of the concrete well wall 100. On the two flanges (flange 15 and flange 2 16), through holes are also provided vertically, and bolts are installed in some of the through holes to fix the ends of the first crossbeam 40 and the second crossbeam 50 together with the flanges to form a basic support. If both the first crossbeam 40 and the second crossbeam 50 are channel steel structures, then the two ends of the middle web of the channel steel structure are connected to the flanges by bolts, thus overlapping to form a whole.

[0029] The support member 20 includes a body (i.e., a U-shaped body 21) and two rows of insert plates 22 disposed on the body. Each row (insert plate 22) includes multiple insert plates 22 arranged alternately in the vertical direction. A cylindrical through hole 211 is formed on the body of the support member 20 and between the two rows of insert plates 22. Correspondingly, two rows of insertion holes (i.e., insertion hole one 131 and insertion hole two 141) are formed on the third arm plate 13 and the fourth arm plate 14, respectively, arranged in the vertical direction. Each row (insert hole) contains multiple insertion holes, and a strip-shaped hole (i.e., strip-shaped hole one 132 and strip-shaped hole two 142) extending in the vertical direction is formed between the two rows of insertion holes. The insert plates 22 on the support member 20 can be inserted into some of the insertion holes, thereby establishing a basic plug-in connection between the support member 20 and the third arm plate 13 and the fourth arm plate.

[0030] The number of insertion holes 131 in the vertical direction and the number of insertion holes 141 in the setting direction in each column are both greater than the number of insertion plates 22 in the vertical direction. Therefore, when the support member 20 forms a plug-in matching assembly relationship with the third arm plate 13 and the fourth arm plate 14 respectively, the multiple insertion plates 22 on it are correspondingly inserted into some of the insertion holes 131 and some of the insertion holes 141.

[0031] The body of the support member 20 corresponds to and matches the ends of the first crossbeam 40 and the second crossbeam 50. If the first crossbeam 40 and the second crossbeam 50 are selected as channel steel structures, the body of the support member 20 is correspondingly disposed between the two flange plates of the channel steel structure, and can contact the lower end face of the upper flange plate to form a support structure. In other words, the first crossbeam 40 and the second crossbeam 50 are both channel steel structures, and the U-shaped body 21 is correspondingly disposed in the channel of the channel steel structure, and the upper end face of the U-shaped body 21 contacts the inner top surface of the channel.

[0032] The stud 30 can pass through the cylindrical through hole 211 and the strip hole, and after a nut is placed at its end, it can fix the support member 20 (the U-shaped body 21) on the third arm plate 13 and the fourth arm plate (14). The cap and nut of the stud 30 can clamp the U-shaped body 21 and the third and fourth arm plates close to each other, so that the root of the insert plate 22 provided on the U-shaped body 21 can be fully inserted into the first insert hole 131 and the second insert hole 141.

[0033] like Figure 5 As shown, wedge surfaces 221 are formed at the root of the insert plate 22 on both the upper and lower end faces. The end of each wedge surface 221 near the main body (i.e., the vertical plate of the U-shaped body 21) extends away from its respective end face. Specifically, the wedge surface 221 on the upper end face extends upwards at the end near the U-shaped body 21; the wedge surface 221 on the lower end face extends downwards at the end near the U-shaped body 21. In this way, after the root of the insert plate 22 is pressed into the first insertion hole 131 and the second insertion hole 141, an interference fit is formed with the port of the insertion hole, increasing the stability of the insertion between the insert plate 22 and the insertion hole. To further improve the insertion firmness between the insert plate 22 and the socket, multiple alternating linear grooves 2211 or multiple protrusions can be provided on the wedge surface 221. This allows the root of the insert plate 22 to undergo compression deformation, enabling a larger interference fit surface to be formed between its root and the port of the socket, resulting in a more stable and reliable insertion connection. The length direction of the linear grooves 2211 and the length direction of the protrusions can be consistent with the length direction of the insert plate 22, thus allowing multiple linear grooves 2211 and multiple protrusions to be alternately distributed in the width direction of the insert plate 22; alternatively, the length direction of the linear grooves 2211 and the length direction of the protrusions can also be consistent with the width direction of the insert plate 22, thus allowing multiple linear grooves 2211 and multiple protrusions to be alternately distributed in the length direction of the insert plate 22.

[0034] The main body of each support member 20 is a U-shaped body 21, and the vertical plate of each U-shaped body 21 is respectively aligned with the end face of the third arm plate 13 and the end face of the fourth arm plate 14. Multiple vertically alternating cylindrical through holes 211 are formed on the vertical plate of each U-shaped body 21, and a stud 30 is disposed at each cylindrical through hole 211. The outer diameter of the smooth section of the stud 30 is the same as the inner diameter of the cylindrical through hole 211.

[0035] This utility model improves the connection structure between the elevator shaft column 10 and the crossbeams (first crossbeam 40, second crossbeam 50) at their joint ends.

[0036] By connecting the first flange 15 and the second flange 16 to both ends of the crossbeam, a relatively long joint length is established. These are then bolted together to form a basic joint connection structure. Next, the support members 20 are fixed to the third arm plate 13 and the fourth arm plate 14, respectively, and these support members 20 further support the ends of the crossbeam, distributing the stress on the connecting bolts between the flanges and the crossbeam. Ultimately, the technical solution of this invention improves the connection stability and reliability of the aluminum elevator shaft structure at the joint position, and enhances its load-bearing capacity and impact resistance.

[0037] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit it. Many aspects of this utility model can be improved without departing from the overall concept. Those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
