Description

[Technical Field]

[0001] This utility model relates to the field of elevator shaft technology, specifically to a standardized component for on-site assembly of steel structure elevator shafts for adding elevators to old buildings. [Background Technology]

[0002] To facilitate people's travel, the installation of elevators in older buildings is becoming increasingly common. Elevator shafts are often installed using a hoisting process, connecting shaft units on both floors in mid-air. Each shaft unit contains four shaft columns, which are welded together at the connection point. Welding requires advanced welding techniques, while on-site processing often results in lower precision and quality, making it difficult to guarantee the quality of the steel structure elevator shaft. Furthermore, it is greatly affected by weather conditions, leading to long construction times, high on-site noise levels, environmental pollution, impact on workers' health, and disruption to residents' rest. Subsequent disassembly and reassembly are also inconvenient.

[0003] Therefore, bolts are also used to connect adjacent shaft columns, which can solve the inconvenience of on-site welding. For example, in an elevator shaft disclosed in application number "202121803063.2", multiple connecting plates are set at the joint of two adjacent square tube columns to solve the problem of on-site welding. Although this solves the problem caused by on-site welding, the method of connecting and fixing with multiple connecting plates has low assembly efficiency during on-site construction, and it is difficult to align and connect adjacent columns during on-site construction.

[0004] In addition, elevator installation projects in old buildings are mostly located in older communities with poor on-site construction conditions. Small cranes cannot enter some of the elevator installation locations, so elevators in these locations cannot be installed in sections as a whole. Instead, they need to be assembled on-site using small components. However, the existing elevator shaft structure is quite complex, resulting in low on-site construction efficiency.

[0005] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0006] The technical problem this utility model aims to solve is to provide a standardized component for on-site assembly of steel structure elevator shafts for adding elevators to old buildings. By setting up a connecting mechanism, adjacent shaft units can be quickly connected, solving the problem of low efficiency caused by welding in the past. At the same time, this application has fewer structural components, which can be standardized for production and sales. In addition, the inner sleeve in the connecting mechanism of this application is fixedly connected to the square tube column in the factory. After being transported to the construction site, it can be inserted into the corresponding square tube column to complete the positioning. The locking component can then lock the inner sleeve to the square tube column, solving the problem of inconvenient positioning between square tube columns in the past.

[0007] To solve the above-mentioned technical problems, this utility model proposes a standardized component for on-site assembly of steel structure elevator shafts for adding elevators to old buildings. It includes precast concrete foundation piles and shaft frames vertically set on the foundation piles, as well as several glass curtain walls set on the outside of the shaft frame and clamping components set on the shaft frame for fixing adjacent glass curtain walls.

[0008] The shaft frame includes several interconnected shaft units and a connecting mechanism for connecting adjacent shaft units. Each shaft unit includes four hollow square tube columns arranged in a vertical direction and several crossbeams connecting two square tube columns on the same side.

[0009] The connection mechanism includes a first connection component for connecting corresponding square tube columns in adjacent shaft units, and a second connection component for connecting the crossbeams between adjacent shaft units and the square tube columns on the same side in adjacent shaft units into a single unit.

[0010] The first connecting assembly includes an inner sleeve fixedly disposed at the upper end of the square tube column, the upper part of the inner sleeve being inserted into the lower end of the corresponding square tube column, and the first connecting assembly also includes a locking member disposed at the upper part of the square tube column to lock the square tube column and the inner sleeve together.

[0011] As described above, a standardized on-site assembly method for adding steel structure shafts to old buildings elevators includes at least two locking components. These two locking components are respectively distributed on the two opposite sides of the square tube column, thereby locking the corresponding inner sleeve side to the side of the square tube column.

[0012] As described above, a standardized on-site assembly method for adding steel structure shafts to old buildings elevators includes a locking component comprising a first fixing hole formed on the side of the inner sleeve and a second fixing hole formed on the square tube column corresponding to the first fixing hole. The locking component also includes a first locking bolt that passes through the first fixing hole and the second fixing hole to lock the side of the inner sleeve to the side of the square tube column.

[0013] The first fixing hole includes a lower fixing hole through which the head of the first locking bolt can pass, and a transition hole that communicates with the lower fixing hole and is only for the screw of the first locking bolt to pass through. The transition hole extends laterally to a locking hole that is only for the screw of the first locking bolt to pass through. The second fixing hole has the same shape as the first fixing hole.

[0014] As described above, in a standardized construction method for on-site assembly of steel structure shafts for adding elevators to old buildings, the first locking bolt has an anti-rotation part formed on its threaded rod that mates with the locking hole to prevent rotation when the first locking bolt is tightened.

[0015] As described above, a standardized on-site assembly method for adding steel structure shafts to old buildings elevators includes a locking component comprising a second locking bolt for locking the inner sleeve to the side of the square tube column. The side of the square tube column opposite the second locking bolt and the side of the inner sleeve are formed with through holes for the second locking bolt to pass through.

[0016] As described above, a standardized on-site assembly method for adding steel structure elevator shafts to old buildings includes a second connecting component comprising a first diagonal brace. The upper end of the first diagonal brace is connected to one end of a crossbeam and the corresponding square tube column in the shaft unit, and the lower end of the first diagonal brace is connected to one end of a crossbeam and the square tube column in an adjacent shaft unit. The first diagonal brace, the corresponding crossbeam, and the square tube column form a triangular structure.

[0017] As described above, a standardized on-site assembly method for adding steel structure elevator shafts to old buildings is used. The shaft unit has two crossbeams, and a second diagonal brace is provided between the crossbeams for connection between the two. The upper end of the second diagonal brace is connected to the lower part of one end of the corresponding crossbeam, and the lower end of the second diagonal brace is connected to the upper part of one end of the corresponding crossbeam. The first diagonal brace, the second diagonal brace, and the corresponding square tube column form a triangular structure, and the central axis of the first diagonal brace, the second diagonal brace, and the crossbeams extends and intersects on the central axis of the square tube column.

[0018] As described above, a standardized on-site assembly method for adding steel structure shafts to old buildings elevators includes a first connecting angle steel at one end of the crossbeam for connecting it to the corresponding square tube column, and a second connecting angle steel at the other end of the crossbeam for connecting the first diagonal brace, the second diagonal brace, and the corresponding square tube column.

[0019] As described above, a standardized on-site assembly method for adding steel structure elevator shafts to old buildings includes a clamping assembly comprising a fixed clamping block connected to the shaft frame, a movable clamping block that cooperates with the fixed clamping block to clamp two adjacent glass curtain walls, a locking member for locking the movable clamping block onto the fixed clamping block to fix the glass curtain wall, and a support plate disposed between the movable and fixed clamping blocks to support the glass curtain wall. The locking member has a fixing part and a connecting part. A T-shaped groove is formed at the fixed clamping block between the two glass curtain walls. The fixing part of the locking member engages with the T-shaped groove. One end of the support plate engages with the T-shaped groove, and the other end of the support plate engages with the movable clamping block. The upper surface of the support plate is higher than the upper end of the connecting part. After passing through the movable clamping block, the connecting part engages with a nut threadedly to lock the movable clamping block.

[0020] As described above, a standardized on-site assembly method for adding steel structure shafts to old buildings elevators includes clamping strips on the inner sides of both the fixed clamping block and the movable clamping block, and rubber pads on the upper part of the support plate.

[0021] Compared with existing technologies, the standardized component-based on-site assembly method for adding steel structure shafts to old buildings has the following advantages:

[0022] 1. This application greatly facilitates the installation process by setting an inner sleeve to align with the square tube column. Compared with the previous method of fixing the square tube column directly on site by welding, the operation is simpler and can avoid the health risks of welding to construction workers.

[0023] 2. The inner sleeve of this application can be directly embedded in the square tube column, which is convenient for positioning and easy for users to install.

[0024] 3. In this application, the elevator shaft has fewer structural components, allowing for standardized production and easy on-site assembly, thus improving construction efficiency. Furthermore, under suitable construction conditions, the shaft units can be assembled in the factory and transported to the construction site, where adjacent units can be quickly fixed together via a connecting mechanism, significantly improving installation efficiency.

Detailed Implementation Methods

[0049] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0050] like Figure 1-17As shown, this utility model includes a standardized component for on-site assembly of a steel structure elevator shaft for adding an elevator to an old building. It includes precast concrete foundation piles 1 and a shaft frame 2 vertically mounted on the foundation piles 1. It also includes several glass curtain walls 3 mounted on the outside of the shaft frame 2 and clamping components 30 mounted on the shaft frame 2 to fix adjacent glass curtain walls 3 vertically. In this embodiment, connectors are pre-installed on the foundation piles 1, formed together with the concrete, with the top of the connectors protruding from the foundation piles 1 and connecting to the shaft frame 2.

[0051] The shaft frame 2 includes several interconnected shaft units 20 and a connecting mechanism 40 for connecting adjacent shaft units 20. Each shaft unit 20 includes four hollow square tubular columns 21 arranged vertically, and several crossbeams 22 connecting two square tubular columns 21 on the same side. It should be noted that the bottom shaft unit 20 is connected to the connector in the foundation pile 1.

[0052] The connecting mechanism 40 includes a first connecting component 41 for connecting corresponding square tube columns 21 in adjacent shaft units 20, and a second connecting component 42 for connecting the crossbeams 22 between adjacent shaft units 20 and the square tube columns 21 on the same side of adjacent shaft units 20 into a single unit. The first connecting component 41 includes an inner sleeve 410 fixedly disposed on the upper end of the square tube column 21, the upper part of the inner sleeve 410 being fitted into the lower end of the corresponding square tube column 21. The first connecting component 41 also includes a locking member disposed on the upper part of the square tube column 21 to lock the square tube column 21 and the inner sleeve 410 together.

[0053] In this embodiment, the first connecting component 41 is fixedly connected to the square tube column 21 in the factory by welding through the inner sleeve 410. During on-site assembly, the inner sleeve 410 is aligned with the square tube column 21 in the bottom shaft unit 20. After alignment, the corresponding square tube columns 21 in the upper and lower shaft units 20 will abut and align. Then, the locking component fixes the square tube column 21 to the inner sleeve 410, thus completing the installation. By setting the inner sleeve 410 to align and connect with the square tube column 21, this application greatly facilitates the installation by the staff. Compared with the previous method of fixing the square tube column 21 directly on-site by welding, the operation is simpler, and the inner sleeve 410 can be directly embedded into the square tube column 21, which is convenient for positioning and installation by the user.

[0054] In this application, there are fewer structural components, which can be standardized for production and facilitate on-site assembly. In addition, the shaft unit 20 can also be assembled in the manufacturing plant and transported to the construction site. Then, adjacent shaft units 20 can be quickly fixed together by the connecting mechanism 40, which greatly improves the installation efficiency.

[0055] like Figures 5 to 10 As shown, as a further embodiment, at least two locking members are provided. The two locking members are respectively distributed on opposite sides of the square tube column 21, thereby locking the side of the inner sleeve 410 to the side of the square tube column 21. By providing a pair of locking members to lock the square tube column 21 and the inner sleeve 410, and with the locking members distributed on opposite sides of the square tube column 21, the force distribution is more balanced. Alternatively, four locking members can be provided, one on each side of the square tube column 21, thereby locking each side of the square tube column 21 to the corresponding side of the inner sleeve 410, thus making the connection between the square tube column 21 and the inner sleeve 410 more secure. In this embodiment, when two locking members are provided, they are symmetrically arranged; similarly, when four locking members are provided, they are distributed on corresponding sides, and the locking members on opposite sides are also symmetrically arranged.

[0056] like Figure 6 , Figure 7 As shown, in a preferred embodiment, the locking member includes a first fixing hole 50 formed on the side of the inner sleeve 410 and a second fixing hole 51 formed on the square tube column 21 and corresponding to the first fixing hole 50. The locking member also includes a first locking bolt 53 that passes through the first fixing hole 50 and the second fixing hole 51 to lock the side of the inner sleeve 410 and the side of the square tube column 21.

[0057] The first fixing hole 50 includes a lower fixing hole 54 through which the head of the first locking bolt 53 passes, and a transition hole 55 communicating with the lower fixing hole 54 and only through which the screw of the first locking bolt 53 passes. The transition hole 55 extends laterally to a locking hole 56 that only through which the screw of the first locking bolt 53 passes. The second fixing hole 51 has the same shape as the first fixing hole 50. The screw of the first locking bolt 53 has an anti-rotation part 57 formed on it, which cooperates with the locking hole 56 to prevent the first locking bolt 53 from rotating when it is locked.

[0058] like Figure 6 , Figure 7As shown, in this embodiment, when the inner sleeve 410 and the square tube column 21 are fixed by the locking member, after the inner sleeve 410 and the square tube column 21 are connected, the first fixing hole 50 and the second fixing hole 51 are exactly aligned. Then, the head of the first locking bolt 53 is inserted into the lower fixing hole 54, and then the first locking bolt 53 is moved so that the threaded part of the first locking bolt 53 passes through the transition hole 55 and reaches the position of the locking hole 56. At this time, the nut is used to lock the first locking bolt 53, thereby locking the inner sleeve 410 and the square tube column 21. In addition, by providing an anti-rotation part 57 on the first locking bolt 53 and cooperating with the locking hole 56, the first locking bolt 53 can be prevented from rotating when the nut is tightened, which facilitates the installation by the workers.

[0059] like Figure 8 , Figure 10 As shown, in another preferred embodiment, the locking component includes a second locking bolt 60 for locking the inner sleeve 410 to the side of the square tube column 21. A through hole 61 is formed on the side of the square tube column 21 opposite to the second locking bolt 60 and on the side of the inner sleeve 410 for the second locking bolt 60 to pass through. In this embodiment, when fixing the square tube column 21 and the inner sleeve 410, the second locking bolt 60 is inserted into the inner sleeve 410 through the through hole 61 on one side of the square tube column 21. The thread of the second locking bolt 60 then passes through the inner sleeve 410 and the square tube column 21 in sequence. Finally, a nut is used to engage with the second locking bolt 60 to lock and fix the inner sleeve 410 and the square tube column 21. It should be noted that when the through hole 61 is provided on one side of the square tube column 21 and the inner sleeve 410, a corresponding hole (not shown in this application) is provided on the other side of the square tube column 21 and the inner sleeve 410 for the second locking bolt 60 to pass through. The second locking bolt 60 is an internal hex bolt, which facilitates tightening. In addition, after the second locking bolt 60 is installed, a plug can be provided at the through hole 61 for sealing. The plug is not shown in this application.

[0060] like Figure 3 , Figure 4As shown, as a further embodiment, the second connecting component 42 includes a first diagonal rod 420. The upper end of the first diagonal rod 420 is connected to one end of the crossbeam 22 and the corresponding square tube column 21 in the shaft unit 20, forming a single unit. The lower end of the first diagonal rod 420 is connected to one end of the crossbeam 22 and the square tube column 21 in the adjacent shaft unit 20, forming a single unit. The first diagonal rod 420, the corresponding crossbeam 22, and the square tube column 21 form a triangular structure. In this embodiment, by connecting two adjacent shaft units 20 through the second connecting component 42, the stability between the shaft units 20 can be enhanced. Furthermore, the connection between the first diagonal rod 420 and the corresponding crossbeam 22 and square tube column 21 in the second connecting component 42 forms a stable triangular structure, thereby making the connection between the two adjacent shaft units 20 more stable.

[0061] like Figure 3 , Figure 4 , Figure 9 , Figure 11 As shown, as a further embodiment, the shaft unit 20 has two crossbeams 22, with a second diagonal brace 23 connecting them. The upper end of the second diagonal brace 23 is connected to the lower part of one end of the corresponding crossbeam 22, and the lower end of the second diagonal brace 23 is connected to the upper part of one end of the corresponding crossbeam 22. The first diagonal brace 420, the second diagonal brace 23, and the corresponding square tube column 21 form a triangular structure, and the central axes of the first diagonal brace 420, the second diagonal brace 23, and the crossbeam 22 extend and intersect at the central axis of the square tube column 21. One end of the crossbeam 22 is provided with a first connecting angle steel 43 for connecting it to the corresponding square tube column 21, and the other end of the crossbeam 22 is provided with a second connecting angle steel 44 for connecting the first diagonal brace 420, the second diagonal brace 23, and the corresponding square tube column 21. By setting two crossbeams 22, the two crossbeams 22 and the second diagonal brace 23 form a Z-shaped structure. The upper end of the second diagonal brace 23 in each shaft unit 20 is connected to the second connecting angle steel 44, and the two ends of the second diagonal brace 23 abut against the corresponding crossbeam 22 and the square tube column 21, respectively, thus making the force distribution more stable. In addition, the two ends of the first diagonal brace 420 abut against the corresponding crossbeam 22 and the square tube column 21, which also makes the force distribution more stable. The corresponding crossbeams 22, the first diagonal brace 420 and the second diagonal brace 23 are connected into one unit by the second connecting angle steel 44, and the central axis of the first diagonal brace 420, the second diagonal brace 23 and the crossbeam 22 extends and intersects the central axis of the square tube column 21, which makes the connection of the entire shaft unit 20 and two adjacent shaft units 20 more stable. In addition, the first diagonal brace 420 and the second diagonal brace 23 have the same structure, which facilitates production.

[0062] like Figure 2 , Figure 5 , Figures 12 to 17As shown, as a further embodiment, the clamping assembly 30 includes a fixed clamping block 31 connected to the shaft frame 2, and a movable clamping block 32 that cooperates with the fixed clamping block 31 to clamp two adjacent glass curtain walls 3. It also includes a locking member 33 for locking the movable clamping block 32 onto the fixed clamping block 31 to fix the glass curtain wall 3, and a support plate 34 disposed between the movable clamping block 32 and the fixed clamping block 31 to support the glass curtain wall 3. The locking member 33 has a fixing part 330 and a connecting part 331. A T-shaped groove 35 is formed at the fixed clamping block 31 located between the two glass curtain walls 3. The fixing part 330 is engaged with the T-slot 35, one end of the support plate 34 is engaged with the T-slot 35, and the other end of the support plate 34 is engaged with the movable clamping block 32. The upper surface of the support plate 34 is higher than the upper end of the connecting part 331. After the connecting part 331 passes through the movable clamping block 32, it engages with the nut thread to lock the movable clamping block 32. The inner side of the fixed clamping block 31 and the inner side of the movable clamping block 32 are both provided with clamping strips 39. The upper part of the support plate 34 is provided with a rubber pad 37. The cross section of the clamping strip 39 is crescent-shaped and its material is aluminum. The clamping strip 39 is provided with a rubber strip to cooperate with the glass curtain wall. It should be noted that the rubber strip is not shown in the figure.

[0063] When fixing the glass curtain wall 3, the movable clamping block 32 is first installed on the shaft frame 2, followed by the mounting plate 34 and locking member 33. Two locking members 33 can be provided, located on both sides of the mounting plate 34. In this embodiment, the locking member 33 is a bolt, with the bolt head being the fixing part 330 and the bolt shank being the connecting part 331. The fixing part 330 is inserted into the T-slot 35. Then, the movable clamping block 32 is installed, with the connecting part 331 protruding from the movable clamping block 32. The movable clamping block 32 is then locked by the threaded engagement of the nut and the connecting part 331. In this embodiment, by setting the T-slot 35 to engage with the locking member 33, installation is facilitated. Compared to the previous method of directly locking the movable clamping block 32 with bolts, it prevents the need to replace the entire fixed clamping block 31 if the threads in it are damaged later. In this application, the bolt head is held in place by the T-slot 35, so even if there is slight wear, it will not affect the use. If the bolt rusts later, it can be replaced directly.

[0064] It should be noted that the support plate 34 and the T-slot 35 also use a snap-fit ​​connection. The support plate 34 has a snap-fit ​​slot 36, which snaps into the opening of the T-slot 35. The support plate 34 is installed in the same way as the bolts, by snapping into one end of the T-slot 35. In addition, the inner side of the movable clamping block 32 is formed with a support groove 38 for supporting the support plate 34, so that the support plate 34 can support the glass curtain wall 3 more stably.

[0065] It should also be noted that in this embodiment, after the support plate 34 is equipped with rubber pads 37, its upper surface is higher than the upper end of the bolt. The glass curtain wall 3 is supported by the rubber pads 37, which can prevent the glass curtain wall 3 from contacting the bolt and prevent damage to the glass curtain wall 3.
