Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to a prefabricated elevator frame module. Background Technology

[0002] Currently, existing elevator frames are mainly divided into two types: cast-in-place and precast assembly. Cast-in-place elevator frames are formed by binding steel bars, supporting formwork, and pouring concrete on the construction site, integrating components such as columns and beams into one piece. Its advantage lies in its good structural integrity and tight connection with the main building. Precast assembly elevator frames, on the other hand, involve prefabricating components such as columns and beams in a factory and then transporting them to the construction site for assembly. Common connection methods include welding and bolting. This method can reduce on-site wet work and improve the precision of component production.

[0003] However, in practical applications, traditional prefabricated elevator frames suffer from low construction efficiency during installation. Taking the common column-beam through-frame system as an example, its assembly requires step-by-step processing, involving numerous on-site welding or bolting procedures. This not only requires skilled technicians but also makes it difficult to guarantee welding quality due to environmental factors and the skill level of the personnel. The large number of bolted connections also consumes considerable time for installation and tightening. Furthermore, these complex connection procedures lead to long construction cycles, increasing labor and equipment rental costs. This problem is particularly pronounced in scenarios with strict time constraints, such as adding elevators to older residential communities. Utility Model Content

[0004] The main purpose of this utility model is to provide a prefabricated elevator frame module, which aims to simplify the on-site connection process, reduce the number of welding and bolts used, achieve rapid assembly, improve the construction efficiency of the prefabricated elevator frame, shorten the construction cycle, reduce construction costs, and at the same time ensure connection strength and structural stability.

[0005] To achieve the above objectives, this utility model proposes a prefabricated elevator frame module, including a bottom column, a top column, a middle column, and a crossbeam. The upper end of the bottom column and the end of the middle column opposite to the bottom column are each provided with a first connecting structure. The lower end of the top column and the end of the middle column opposite to the top column are each provided with a second connecting structure. Both ends of the crossbeam are provided with a third connecting structure.

[0006] The first connection structure includes a fixing slot and a fixing opening. The fixing slot is located at the upper end of the bottom column or at the end of the middle column away from the bottom column and extends into the bottom column or the middle column. The fixing opening is located on the side of the bottom column or the middle column and is located inside the fixing slot.

[0007] The second connection structure includes a first fixing protrusion and several fixing ribs. The first fixing protrusion is located at the lower end of the top column or the end of the middle column away from the top column. The fixing ribs are located at the ends of the top column or middle column away from the first fixing protrusion.

[0008] The third connection structure includes a second fixing protrusion and a plurality of first limiting holes. The second fixing protrusion is located at both ends of the crossbeam, and the first limiting holes are located on the second fixing protrusion.

[0009] The second fixing protrusion is embedded in the fixing slot through the fixing opening, and the first fixing protrusion is embedded in the fixing slot from the upper end of the bottom column or the end of the middle column away from the bottom column. The fixing rib is embedded in the first limiting hole.

[0010] In one possible implementation, a plurality of reinforcing plates are fixedly connected inside the fixing slot, and the plurality of reinforcing plates are respectively located on the upper and lower sides of the fixing opening. The reinforcing plates are provided with a plurality of second limiting holes, and the fixing rib is embedded in the second limiting holes.

[0011] In one possible implementation, the plurality of the fixing ribs, the first limiting hole, and the second limiting hole are all arranged in a rectangular structure.

[0012] In one possible implementation, the fixing rib is made of steel, and the surface of the fixing rib is provided with threads or knurled grooves to enhance the friction between the fixing rib and the first limiting hole and ensure connection stability.

[0013] In one possible implementation, both the first fixing protrusion and the second fixing protrusion are provided with guide ramps to assist in quick alignment and insertion, thereby improving installation efficiency.

[0014] In one possible implementation, the reinforcing plate is made of steel and is fixed in a fixed slot by welding to enhance the load-bearing capacity of the node.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] This utility model's technical solution involves setting a first connecting structure with fixing slots and fixing openings in the bottom and middle columns, a second connecting structure with first fixing protrusions and fixing ribs in the top and middle columns, and a third connecting structure with second fixing protrusions and first limiting holes at both ends of the crossbeam. This allows the second fixing protrusions of the crossbeam to be inserted into the fixing slots through the fixing openings, the first fixing protrusions of the top or middle columns to be inserted into the fixing slots, and the fixing ribs to be inserted into the first limiting holes of the crossbeam. This enables modular and rapid assembly of each component through the cooperation of prefabricated protrusions, slots, and rib holes, eliminating traditional welding or a large number of bolt connection processes, shortening on-site construction time, and improving the construction efficiency of prefabricated elevator frames.

[0023] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0025] like Figures 1-4 As shown, this embodiment proposes a prefabricated elevator frame module, including a bottom column 1, a top column 3, a middle column 2, and a crossbeam 4. The upper end of the bottom column 1 and the end of the middle column 2 away from the bottom column 1 are provided with a first connecting structure. The lower end of the top column 3 and the end of the middle column 2 away from the top column 3 are provided with a second connecting structure. The two ends of the crossbeam 4 are provided with a third connecting structure.

[0026] Bottom column 1, top column 3, middle column 2, and crossbeam 4 serve as the basic components of the prefabricated elevator frame module. They respectively bear the vertical loads supporting the bottom, top, and intermediate floors of the elevator. Simultaneously, the crossbeam 4 connects with the columns to form a frame structure, collectively resisting horizontal loads such as wind loads and seismic forces. By disassembling the elevator frame into these prefabricated components, factory production is achieved, reducing on-site construction workload, improving production efficiency and component quality stability, while also facilitating transportation and on-site assembly, and shortening the construction cycle.

[0027] The first connection structure includes a fixing slot 11 and a fixing opening 12. The fixing slot 11 is located at the upper end of the bottom column 1 or at the end of the middle column 2 away from the bottom column 1 and extends into the bottom column 1 or the middle column 2. The fixing opening 12 is located on the side of the bottom column 1 or the middle column 2 and is located inside the fixing slot 11.

[0028] In the first connection structure, the fixing slot 11 is located at the upper end of the bottom column 1 or one end of the middle column 2 and extends inward. The fixing opening 12 is located on the side and inside the fixing slot 11, providing installation space for the connection between the crossbeam 4 and the upper column. During installation, the second fixing protrusions 41 at both ends of the crossbeam 4 can be easily inserted into the fixing slot 11 through the fixing opening 12, and the first fixing protrusion 21 of the upper column can also be inserted from the opening of the fixing slot 11, realizing rapid positioning and preliminary connection between the crossbeam 4 and the column, and between the columns. This structural design changes the traditional welding or large number of bolt connections, greatly simplifies the installation process, reduces the technical requirements for installation workers, makes on-site installation more efficient and faster, and significantly shortens the construction time.

[0029] The second connection structure includes a first fixing protrusion 21 and several fixing ribs 22. The first fixing protrusion 21 is located at the lower end of the top column 3 or at the end of the middle column 2 away from the top column 3. The fixing ribs 22 are located at the ends of the top column 3 or the middle column 2 away from the first fixing protrusion 21.

[0030] In the second connecting structure, the first fixing protrusion 21 is located at the lower end of the top column 3 or one end of the middle column 2. The fixing rib 22 is connected to the end of the first fixing protrusion 21 and is used to cooperate with the first connecting structure to achieve a firm connection between the columns and between the columns and the crossbeam 4. The first fixing protrusion 21 can be embedded in the fixing slot 11 of the lower column, serving to position and bear part of the vertical load; while the fixing rib 22 can pass through the first limiting hole 42 on the second fixing protrusion 41 of the crossbeam 4 and the second limiting hole 14 in the reinforcing plate 13, tightly connecting the top column 3, the middle column 2, and the crossbeam 4 into a whole. This connection method not only ensures the reliability of the connection and effectively transmits various loads, but also, compared with traditional connection methods, the installation process is simpler and faster, enhancing the integrity and stability of the frame structure and improving construction efficiency.

[0031] The third connecting structure includes a second fixing protrusion 41 and a plurality of first limiting holes 42. The second fixing protrusion 41 is located at both ends of the crossbeam 4, and the first limiting holes 42 are located on the second fixing protrusion 41. The second fixing protrusion 41 is embedded into the fixing slot 11 through the fixing opening 12. The first fixing protrusion 21 is embedded into the fixing slot 11 from the upper end of the bottom column 1 or the end of the middle column 2 away from the bottom column 1. The fixing rib 22 is embedded into the first limiting holes 42.

[0032] In the third connection structure, the second fixing protrusion 41 is located at both ends of the crossbeam 4, and the first limiting hole 42 is set on the second fixing protrusion 41, which is used to connect and fix the crossbeam 4 to the column. During installation, the second fixing protrusion 41 can be precisely inserted into the fixing opening 12 and fixing slot 11 of the column to achieve rapid positioning of the crossbeam 4. The first limiting hole 42 is used to cooperate with the fixing rib 22. When the fixing rib 22 passes through the first limiting hole 42 and the second limiting hole 14 of the reinforcing plate 13, the crossbeam 4 can be firmly fixed to the column. This structure makes the installation of the crossbeam 4 simple and easy to operate, without the need for complicated connection processes, while ensuring the strength and stability of the connection between the crossbeam 4 and the column, improving the overall performance of the elevator frame module, and accelerating the construction progress.

[0033] Several reinforcing plates 13 are fixedly connected inside the fixing slot 11. The reinforcing plates 13 are located on the upper and lower sides of the fixing opening 12, respectively. Several second limiting holes 14 are provided in the reinforcing plates 13, and the fixing ribs 22 are embedded in the second limiting holes 14. The reinforcing plates 13 are made of steel and are fixed in the fixing slot 11 by welding to enhance the load-bearing capacity of the node.

[0034] The reinforcing plates 13 inside the fixed slot 11 are located on the upper and lower sides of the fixed opening 12, and the reinforcing plates 13 have second limiting holes 14, which enhance the strength and stability of the connection node. The reinforcing plates 13 can effectively disperse the stress concentration phenomenon of the fixed slot 11 under stress, and improve the load-bearing capacity of the connection part; while the second limiting holes 14 cooperate with the fixing ribs 22 to further strengthen the connection between the column and the beam 4, so that the fixing ribs 22 are not only connected to the first limiting holes 42 of the beam 4, but also connected to the reinforcing plates 13, forming a more stable connection system. This design ensures that the connection node will not be easily damaged under various loads, significantly improving the overall strength and durability of the elevator frame module, while optimizing and strengthening the connection structure without adding too many complex processes.

[0035] In this embodiment, the fixing ribs 22, the first limiting hole 42, and the second limiting hole 14 are all arranged in a rectangular structure. The fixing ribs 22 are made of steel, and the surface of the fixing ribs 22 is provided with threads or knurled grooves to enhance the friction between the fixing ribs 22 and the first limiting hole 42 and ensure connection stability.

[0036] A series of rectangularly arranged fixing ribs 22, first limiting holes 42, and second limiting holes 14, through their orderly layout, ensure precise alignment of the components during connection, greatly improving installation accuracy and efficiency. The fixing ribs 22, made of steel with threads or knurled grooves on their surface, reliably bear and transmit loads between components due to the high strength and toughness of steel. The special design of the threads or knurls significantly enhances the friction between the fixing ribs 22 and the first limiting holes 42 by increasing surface roughness and mechanical interlocking effect. This not only effectively prevents the fixing ribs 22 from loosening or slipping under stress, ensuring the tightness and stability of the prefabricated elevator frame module connection, but also avoids safety hazards caused by connection failure. Simultaneously, the rectangular arrangement facilitates standardized production during factory prefabrication, reducing processing difficulty and costs, and allows for rapid positioning and insertion during on-site installation, further improving construction efficiency and ensuring the reliability and safety of the overall elevator frame structure during long-term use.

[0037] In this embodiment, both the first fixing protrusion 21 and the second fixing protrusion 41 are provided with guide slopes 43 to assist in quick alignment and insertion, thereby improving installation efficiency.

[0038] The guide ramps 43 provided on the first fixing protrusion 21 and the second fixing protrusion 41 provide precise and efficient guidance for the splicing process of each component. During the installation of the prefabricated elevator frame module, the guide ramps 43 can automatically align the connection parts of adjacent components by virtue of their tilt angle, avoiding misalignment or jamming during installation. This makes the insertion operation between the first fixing protrusion 21 and the fixing slot 11, and between the second fixing protrusion 41 and the fixing opening 12 and slot, smoother and more unobstructed. This structural design significantly reduces the installation difficulty, allowing even ordinary installers to quickly get started, greatly reducing the time spent on repeated adjustments and alignments during on-site installation, and making the originally complex splicing process simpler and faster. With the assistance of the guide ramps 43 for quick alignment and insertion, the installation efficiency is greatly improved, effectively shortening the construction cycle of the entire prefabricated elevator frame module. At the same time, it reduces component wear and damage that may be caused by improper installation, ensuring the integrity of the components and the installation quality, reducing construction costs and later maintenance costs, and providing a reliable guarantee for the rapid and efficient construction of the prefabricated elevator frame.
