Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an integrated elevator shaft. Background Technology

[0002] Traditional elevator retrofitting typically involves multiple steps and a complex process. First, a simple elevator frame structure needs to be manufactured in a factory and then transported to the construction site for assembly. During this process, key components such as guide rails, counterweight frames, external curtain walls, elevator doors, and traction machines need to be installed on-site. Another method is a monolithic on-site welding assembly, where most of the assembly work is completed on the ground, and then it is lifted to the designated location using hoisting equipment. Both methods share some drawbacks. Firstly, the construction period is long, especially the on-site assembly and commissioning phases, which not only consumes a significant amount of time but also increases the overall project cost. Furthermore, factors during transportation and installation, such as improper handling or installation, can cause structural deformation, requiring rework and further extending the construction period and increasing additional costs.

[0003] Therefore, for traditional elevator installation, improving production efficiency, shortening the construction cycle, and reducing rework caused by deformation have become urgent problems to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide an integrated elevator shaft to solve the technical problems of low production efficiency, long construction period and easy deformation of structural components in traditional elevator installation.

[0005] This application is achieved through the following technical solution, specifically:

[0006] An integrated elevator shaft is provided, comprising at least three sets of shaft frames assembled sequentially from bottom to top. Each shaft frame includes a cuboid frame composed of columns and beams. The top and bottom surfaces of the cuboid frame are connected to a support frame. Each support frame includes two staggered support rods, with each end of the support rods being movably connected to two diagonally opposite columns.

[0007] In this solution, the modular design and assembly of the shaft frame reduces the need for on-site splicing, welding, and assembly steps required in traditional elevator retrofitting, thus improving production efficiency. Furthermore, adding support frames to the top and bottom surfaces of the shaft frame, using staggered support rods and movable connections to the columns, effectively enhances the overall rigidity and stability of the integrated elevator shaft, preventing structural deformation caused by improper handling or installation during transportation and installation.

[0008] As an improvement to the support rod in this application, the support rod has corresponding pin holes at both ends and on the side of the column, and the support rod is connected to the column by a pin.

[0009] As another improvement to the support rod in this application, the support rod includes a threaded sleeve and two threaded rods respectively sleeved at both ends of the threaded sleeve.

[0010] As an improvement to the column in this application, the column has a first docking plate on its upper top surface and a second docking plate on its lower top surface. The second docking plate has a protruding positioning pin, and the first docking plate has a positioning hole corresponding to the position of the positioning pin.

[0011] Furthermore, the first docking plate and the second docking plate are provided with a number of mounting holes at corresponding positions, and the mounting holes at corresponding positions have the same specifications.

[0012] As an improvement to the shaft frame in this application, the at least three sets of shaft frames include pit segments, standard segments and top segments spliced ​​from bottom to top. The pit segments, standard segments and top segments are provided with hall doors and rail system pre-installation components on one facade in the same direction. The other three facades are provided with external wall installation supports. The standard segment includes at least one set of the standard segments.

[0013] Furthermore, the column of the pit segment extends downward with a pre-embedded connecting component, and the side surface of the pre-embedded connecting component is provided with several bolts, the positions of which correspond to the positions of the concrete pre-embedded parts.

[0014] The beneficial effects of this application are as follows:

[0015] The proposed solution utilizes modular design and assembly of the shaft frame, reducing the on-site splicing, welding, and assembly steps required in traditional elevator retrofitting, thus improving production efficiency. Furthermore, by adding support frames to the top and bottom surfaces of the shaft frame, and using staggered support rods that are movably connected to the columns, the overall rigidity and stability of the integrated elevator shaft are effectively enhanced, preventing structural deformation caused by improper handling or installation during transportation and installation.

[0016] In addition to the technical problems solved by this utility model, the technical features constituting the technical solution, and the advantages brought about by the technical features of these technical solutions as described above, other technical problems that this utility model can solve, other technical features contained in the technical solution, and the advantages brought about by these technical features will be further explained in detail with reference to the accompanying drawings.

[0025] The following will be combined with the appendix Figures 1-6 The embodiments of the technical solution of this application are described in detail below. The following embodiments are only used to illustrate the technical solution of this application more clearly, and are therefore only examples and should not be used to limit the scope of protection of this application.

[0026] In view of the problems existing in the background technology or products, Figure 1 A schematic diagram of a set of shaft frames in an embodiment of this application is shown. Figure 1 As shown in the figure, this application embodiment provides an integrated elevator shaft, which includes at least three sets of shaft frames 1 spliced ​​from bottom to top. The shaft frame 1 includes a cuboid frame composed of columns 11 and beams 12. The top and bottom surfaces of the cuboid frame are connected to a support frame 2. The support frame 2 includes two staggered support rods 21, and the two ends of the support rods 21 are movably connected to the two diagonally opposite columns 11.

[0027] Specifically, the integrated elevator shaft (hereinafter referred to as "shaft") in this embodiment is composed of at least three sets of shaft frames 1 spliced ​​sequentially from bottom to top. Each set of shaft frames 1 consists of columns 11 and beams 12 forming a stable cuboid frame structure. This modular design allows each set of shaft frames 1 to be prefabricated in the factory. On-site, each set of shaft frames 1 only needs to be hoisted and spliced ​​in a certain order, thereby reducing the steps of splicing, welding, and assembly required on-site in traditional elevator installation and improving production efficiency. The two ends of the support rods 21 are connected to two diagonally opposite columns 11 by movable connections to form an "X"-shaped support frame 2. The staggered support rods 21 can effectively distribute and bear the stress that the shaft frame 1 may be subjected to during transportation and installation, thereby enhancing the overall rigidity and stability of the columns 11 and beams 12 and preventing deformation of the columns 11 and beams 12 due to improper handling or installation. The movable connection method simplifies the assembly and disassembly of the support rod 21, making it easy to disassemble the support frame 2 after each set of shaft frames 1 is assembled. This design ensures both the flexibility of the structure and the stability when subjected to external forces.

[0028] Continue reading Figure 1 In order to achieve the movable connection of the support frame 2, in one implementation, the two ends of the support rod 21 and the side of the column 11 are provided with corresponding pin holes, and the support rod 21 and the column 11 are connected by a pin 13.

[0029] Specifically, each end of the support rod 21 is provided with a pin hole that mates with the pin 13. The diameter and shape of the pin hole match the pin 13 to ensure reliable connection and easy disassembly. The side of the column 11, i.e., the area where the support rod 21 is connected, is also provided with a pin hole corresponding to the pin hole at the end of the support rod 21 to ensure the accuracy and stability of the connection. When the support frame 2 needs to be installed, the pins 13 at both ends of the support rod 21 are inserted into the pin holes on the side of the column 11, and the pins 13 are rotated to the locked position, thereby connecting the support rod 21 to the column 11. When the support frame 2 needs to be disassembled, simply rotate the pins 13 to pull them out of the pin holes of the support rod 21 and the column 11 to complete the disassembly, improving the efficiency and convenience of installation and disassembly, and ensuring the reliability of the connection.

[0030] Figure 2 yes Figure 1 A top view of the middle shaft frame, as shown below. Figure 2 As shown, in one implementation, the support rod 21 includes a threaded sleeve 22 and two threaded rods 23 respectively sleeved at both ends of the threaded sleeve 22.

[0031] Specifically, the threaded sleeve 22 is a hollow structure with threads on its inner wall that match the threaded rod 23, allowing the threaded rod 23 to be adjusted in length and width within the threaded sleeve 22 by rotation. One end of the threaded rod 23 has an external thread that engages with the internal thread of the threaded sleeve 22, and the other end has a pin hole. By rotating the threaded rod 23, its position within the threaded sleeve 22 can be changed, thereby adjusting the overall length of the support rod 21 to accommodate the support requirements of shaft frames 1 of different sizes and specifications. The thread structure is not shown in the diagram.

[0032] Figure 3 yes Figure 1 Another structural view of the central shaft frame. (See diagram below.) Figure 2 and 3 As shown, in one implementation, the upper top surface of the column 11 is provided with a first docking plate 111, and the lower top surface is provided with a second docking plate 112. The second docking plate 112 is provided with a protruding positioning pin 113, and the first docking plate 111 is provided with a positioning hole 114 corresponding to the position of the positioning pin 113.

[0033] Specifically, in this embodiment, a first docking plate 111 and a second docking plate 112 are respectively provided at the upper and lower ends of the column 11 for connection or docking with the adjacent shaft frame 1.

[0034] To ensure rapid and accurate alignment between the two mating plates, a raised positioning pin 113 is designed on the upper surface of the second mating plate 112. The positioning pin 113 is a rigid metal or plastic rod of a certain length, with a round or flat top to prevent damage to other components. A positioning hole 114 is provided at a corresponding position on the first mating plate 111 to engage with the positioning pin 113, achieving precise alignment of the two mating plates and forming a closed structure. Compared to existing technologies that place the mating plates at the corners of the crossbeam 12 or at the connection between the column 11 and the crossbeam 12, this embodiment places the mating plates on the upper and lower top surfaces of the column 11. This better strengthens the vertical support of the column 11, better distributes and transmits vertical loads, improves the load-bearing capacity of the shaft frame 1, and avoids the problem of low docking efficiency caused by deformation or misalignment at the connection point of the shaft frame 1.

[0035] Preferably, the first docking plate 111 and the second docking plate 112 are further provided with a plurality of mounting holes 115 at corresponding positions, and the mounting holes 115 at corresponding positions have the same specifications. Specifically, these mounting holes 115 have the same specifications, such as diameter, depth and other parameters, and can be connected using the same type of bolts, screws or other fasteners, thereby enhancing the connection strength of the well frame 1 and adapting to installation requirements under different conditions.

[0036] Figure 4This application provides a schematic diagram of a structure for an integrated elevator shaft according to an embodiment of the present application. Figure 5 It shows Figure 4 Enlarged structural diagram of the middle and top layers. Figure 6 It shows Figure 4 A magnified structural diagram of the middle pit segment. (See diagram below.) Figures 4-6 As shown, in one implementation, the at least three sets of shaft frames 1 include bottom pit segments 3, standard segments 4 and top layer segments 5, which are spliced ​​from bottom to top. The bottom pit segments 3, the standard segments 4 and the top layer segments 5 are all provided with hall doors and rail system pre-installation components on one facade in the same direction. The other three facades are all provided with external wall installation supports. The standard segments 4 include at least one set of standard segments 4.

[0037] Specifically, the aforementioned hall doors and pre-installed rail components include one or more of the following: car guide rails, counterweight components, elevator doors, and door drive devices. These components are manufactured and assembled in the factory, eliminating the need for on-site installation and further improving the efficiency of shaft assembly. The top-floor segment 5 is also pre-installed with a traction machine assembly, serving as the power source for the elevator car's lifting and lowering. The aforementioned external wall mounting supports include at least one type of support structure made of various materials such as glass, aluminum panels, aluminum composite panels, and color steel panels. The number of standard segments 4 is adjusted according to the shaft height specifications, improving the shaft's flexibility and adaptability. The structure of standard segment 4 can be found in [reference needed]. Figures 1-3 A structural diagram.

[0038] Continue reading Figure 6 Preferably, the column 11 of the pit segment 3 extends downward with a pre-embedded connecting member 31, and the side surface of the pre-embedded connecting member 31 is provided with a number of bolts 32, the position of the bolts 32 corresponding to the position of the concrete pre-embedded part.

[0039] Specifically, the embedded connecting member 31 is designed to achieve a reliable connection between the pit segment 3 and the underlying concrete embedded parts. The embedded connecting member 31, through its downward extension, can penetrate deep into the concrete embedded parts, thereby ensuring the stability and load-bearing capacity of the shaft frame 1. As a preferred option, the embedded connecting member 31 has an I-beam structure. The bolts 32 on the side of the embedded connecting member 31 are positioned corresponding to the concrete embedded parts, ensuring the accuracy and stability of the connection and achieving reliable fixation between the pit segment 3 and the concrete structure.
