Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a prefabricated elevator connection to the original concrete structure. Background Technology

[0002] In existing building renovation projects, the demand for prefabricated elevators is gradually increasing, and the connection nodes between prefabricated elevators and existing building concrete are of particular importance.

[0003] In related technologies, prefabricated elevator shafts are generally framed by four steel columns. The shaft is connected to the building by two connectors and fixed by the combination of anchor plates and bolts. The two connectors can rotate relative to each other within a certain range to adapt to wind loads.

[0004] However, the aforementioned technologies have some drawbacks. The settlement levels of the new elevator and the existing building differ, and the existing connection methods cannot solve the problem of uneven settlement. On the other hand, the stress caused by elevator operation and ground vibration will be directly transmitted to the existing building, which may lead to damage to the original structure. Therefore, a connection node that solves the above problems is needed. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides a prefabricated elevator connection component to the original concrete structure.

[0006] The technical solution provided in this application for a prefabricated elevator and its connection to the original concrete structure is as follows: A prefabricated elevator and its connection to the original concrete structure includes:

[0007] A first connecting assembly, comprising an anchor plate and a fixing plate, wherein the anchor plate is fixedly connected to the original concrete structure and the fixing plate is fixedly installed on the anchor plate;

[0008] The second connecting component includes a connector and a sliding member. The two ends of the connector are movably connected to the fixed plate and fixedly connected to the sliding member, respectively. The connector can move horizontally relative to the length direction of the fixed plate, and the sliding member is slidably connected to the steel column on which the elevator shaft is installed.

[0009] By adopting the above technical solution, the prefabricated elevator and the original concrete connection can connect the original concrete building with the steel column of the elevator shaft. The connection can move horizontally relative to the length of the fixed plate, which can adapt to the stress caused by vibration. The sliding part can slide on the steel column, which can adapt to the uneven settlement of the new elevator and the existing building, and prevent damage to the structure of the existing building. On the other hand, it helps to adapt to the dimensional deviation and position adjustment during the installation process, which facilitates the installation and construction of the prefabricated elevator.

[0010] Preferably, the anchor plate is fixedly installed on the original concrete structure by anchor bolts, the fixing plate is vertically installed on the anchor plate and parallel to the ground, and a rib plate is fixedly installed between the fixing plate and the anchor plate.

[0011] By adopting the above technical solution, the anchor plate can be fixed to the original concrete structure using anchor bolts, which can make the first connecting component firmly connected to the original concrete structure. The fixing plate is installed vertically on the anchor plate and parallel to the ground to facilitate the movable connection of subsequent connecting parts. The installation of ribs between the fixing plate and the anchor plate can enhance the stability of the connection between the two.

[0012] Preferably, two ribs are provided on the upper and lower sides of the fixing plate, and the ribs are perpendicular to the anchor plate and the fixing plate.

[0013] By adopting the above technical solution, the anchor plate of the first connecting component is fixedly connected to the original concrete structure. The fixing plate is fixed on the anchor plate and parallel to the ground. Two ribs are vertically arranged on the upper and lower sides of the fixing plate and perpendicular to the anchor plate and the fixing plate, which enhances the connection strength and stability between the fixing plate and the anchor plate.

[0014] Preferably, a limiting groove is provided at one end of the connector near the fixing plate. The limiting groove has a cross-shaped structure and is configured to cooperate with the fixing plate and the rib plate. The fixing plate and the rib plate are engaged and connected with the connector.

[0015] By adopting the above technical solution, the cross-shaped limiting groove is engaged with the fixing plate and rib plate, which can make the connector more stably connected with the first connecting component, ensuring the stability and accuracy of the connector when it moves horizontally on the fixing plate, thereby enhancing the overall connection stability between the prefabricated elevator and the original concrete connector.

[0016] Preferably, the limiting groove includes a first limiting groove and a second limiting groove, the first limiting groove and the second limiting groove are perpendicularly arranged and the second limiting groove is engaged with the fixing plate, the depth of the first limiting groove is less than the depth of the second limiting groove, and the length of the rib plate perpendicular to the anchor plate is less than the length of the fixing plate perpendicular to the anchor plate.

[0017] By adopting the above technical solution, the connector is engaged with the fixed plate and rib plate, which restricts the movement direction of the connector and enables the connector to move horizontally stably relative to the length direction of the fixed plate. The design of the first limiting groove and the second limiting groove being set perpendicularly and having different depths, and the rib plate and the fixed plate having different lengths, further ensures precise matching, tight engagement, and improved connection stability, thereby achieving a reliable connection between the prefabricated elevator and the original concrete structure.

[0018] Preferably, the fixing plate has a first bolt hole at one end near the connector, and two first bolt holes are spaced apart along the length of the fixing plate. The connector has a first elongated hole at one end near the fixing plate that matches the first bolt hole.

[0019] By adopting the above technical solution, two first bolt holes spaced apart along the length direction are provided on the fixing plate, and a first elongated hole is provided on the connector, which enables the movable connection between the first connecting component and the second connecting component. This allows the connector to move horizontally relative to the length direction of the fixing plate, making it easy to adjust the position of the connector to adapt to different installation requirements. Furthermore, by using bolts passing through the first elongated hole and the first bolt hole, the connector and the fixing plate can be effectively fixed, ensuring the stability of the connection.

[0020] Preferably, the length of the first elongated hole is greater than the relative distance between any two points on the first bolt holes.

[0021] By adopting the above technical solution, the connector can move flexibly horizontally within a wider range relative to the length of the fixed plate, adapting to changes in the relative distance between the existing building and the elevator caused by external forces, meeting different assembly requirements, better adapting to possible positional deviations when the prefabricated elevator is connected to the original concrete structure, and improving the adjustment flexibility and convenience during the assembly process.

[0022] Preferably, the sliding member includes a support plate and a sliding block. The support plate is configured to cooperate with the connecting member. The support plate is perpendicular to the sliding block, and ribs are added between the support plate and the sliding block.

[0023] By adopting the above technical solution, the anchor plate of the first connecting component of the prefabricated elevator and the original concrete structure is fixed to the original concrete building, and the fixing plate is installed on the anchor plate; the connecting piece of the second connecting component is movably connected to the fixing plate and fixedly connected to the sliding piece, and can move horizontally, with the sliding piece slidably connected to the steel column. Based on this, the sliding piece is equipped with a support plate and a sliding block, which are vertically arranged and reinforced with ribs, making the sliding piece more stable in conjunction with the connecting piece, enhancing the structural strength of the sliding piece, and thus improving the overall stability of the connecting piece.

[0024] Preferably, the sliding block is concave to fit the steel column, the sliding block has a second bolt hole, and the steel column has a second elongated hole.

[0025] By adopting the above technical solution, the fit between the sliding block and the steel column is improved, and the sliding block and the steel column can be flexibly connected and their positions adjusted by using the second bolt hole and the second oblong hole.

[0026] Preferably, the cross-section of the connector is a rhomboid structure.

[0027] By adopting the above technical solution, the anchor plate of the first connecting component is fixedly connected to the original concrete building, and the fixing plate is fixedly installed on the anchor plate; the two ends of the connector of the second connecting component are respectively movably connected to the fixing plate and fixedly connected to the sliding member. The connector can move horizontally relative to the length direction of the fixing plate, and the sliding member is slidably connected to the steel column of the elevator shaft, realizing the connection between the prefabricated elevator and the original concrete structure; on this basis, the cross section of the connector is a rhomboid structure, which can optimize the mechanical properties of the connector, improve its load-bearing capacity and stability, and make it easier to cooperate with other components for installation.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By setting up a first connection component and a second connection component, there is no need for on-site concrete pouring, welding, or simple bolt connection. This avoids the problems of long on-site pouring construction cycle and unstable connection quality affected by various factors. It also avoids the defects of welding, which has high process requirements and is easy to damage the original concrete structure, as well as bolt connection, which is easy to loosen. This can shorten the construction period, reduce construction costs, and improve connection quality and safety.

[0030] 2. The connector can move horizontally relative to the length of the fixed plate, and the sliding part is slidably connected to the steel column of the elevator shaft, which can adapt to the displacement changes such as vibration generated during elevator operation and ensure the stability of the connection part.

[0035] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0036] For concrete structures such as old residential areas, historical buildings, and commercial buildings that require elevator installation, the foundations of older buildings have generally stabilized after long-term settlement. However, the foundations of buildings where elevators are installed will continue to settle in the future. This is especially true in areas prone to uneven settlement or frequent vibrations, such as soft soil areas and earthquake zones. The tensile / compressive stresses generated by the differential settlement will be transmitted to the original building structure, potentially leading to concrete cracking or failure of connection joints, posing safety risks. In addition, the dynamic loads generated by elevator operation (such as start-stop and track friction) and external vibrations (such as wind loads and traffic vibrations) will be directly transmitted to the original building through rigid connections. Particularly in older buildings, the existing structure may not be able to withstand the added weight and pressure, posing a threat to building safety in the long run.

[0037] refer to Figure 1 This application provides a prefabricated elevator and original concrete structure connection component, including a first connection component 1 and a second connection component 2. The first connection component 1 is fixedly connected to the original concrete building, and one end of the second connection component 2 is movably connected to the first connection component 1, while the other end is slidably connected to the steel column 3 of the elevator shaft. This connection method makes the connection between the prefabricated elevator and the original concrete structure more flexible and stable, and can adapt to certain displacement changes, avoiding the connection instability problem caused by the defects of traditional connection methods.

[0038] refer to Figure 2 Specifically, the first connecting component 1 includes an anchor plate 11 and a fixing plate 12. The anchor plate 11 is a metal sheet, usually made of high-strength steel, and its shape is generally rectangular or square. In practical applications, the anchor plate 11 can be fixedly connected to the original concrete structure in various ways; here, it is fixed to the original concrete structure using anchor bolts. An anchor bolt is a special type of bolt that can be firmly embedded in the original concrete structure, providing a stable foundation for the entire connecting component 21. The fixing plate 12 is also made of metal; it is installed vertically on the anchor plate 11 and parallel to the ground. This arrangement allows the fixing plate 12 to better bear the force from the second connecting component 2.

[0039] refer to Figure 2To enhance the connection strength between the fixing plate 12 and the anchor plate 11, a rib plate 13 is fixedly installed between them. The rib plate 13, also made of steel, serves to strengthen the structure, similar to a supporting beam in a bridge. Two rib plates 13 are provided, located on the upper and lower sides of the fixing plate 12 respectively, and perpendicular to both the anchor plate 11 and the fixing plate 12. The anchor plate 11, fixing plate 12, and rib plate 13 can be integrally connected by welding. Besides this common arrangement, in some special cases, triangular reinforcing ribs can be used instead of the rib plate 13 to achieve a similar strengthening effect.

[0040] More specifically, the fixed plate 12 is vertically mounted on the anchor plate 11 to form a stable planar structure, while the rib plate 13 further enhances the stability of this structure. When subjected to external forces, such as vibrations generated by elevator operation or wind, the rib plate 13 can distribute the force to the anchor plate 11 and the fixed plate 12, avoiding stress concentration and thus ensuring the overall stability of the first connecting assembly 1.

[0041] refer to Figure 2 and Figure 3 Specifically, the second connecting component 2 includes a connector 21 and a sliding member 22. The connector 21 has a rhomboid cross-section. This unique structural design allows the connector 21 to distribute force more evenly when under stress, improving its load-bearing capacity. The two ends of the connector 21 have different connection methods: one end is movably connected to the fixed plate 12, and the other end is fixedly connected to the sliding member 22. A limiting slot 211 is provided at the end of the connector 21 near the fixed plate 12. The limiting slot 211 has a cross-shaped structure and is designed to cooperate with the fixed plate 12 and the rib plate 13.

[0042] The limiting slot 211 includes a first limiting slot 2111 and a second limiting slot 2112. The first limiting slot 2111 and the second limiting slot 2112 are perpendicularly arranged, and the second limiting slot 2112 engages with the fixing plate 12. The first limiting slot 2111 engages with the rib plate 13. The depth of the first limiting slot 2111 is less than the depth of the second limiting slot 2112, and the length of the rib plate 13 perpendicular to the anchor plate 11 is less than the length of the fixing plate 12 perpendicular to the anchor plate 11. This special limiting slot 211 design allows the connector 21 to move horizontally relative to the length direction of the fixing plate 12, while ensuring that the connector 21 does not detach from the fixing plate 12. In addition, the shape of the limiting slot 211 can also be adjusted according to the actual situation. For example, a trapezoidal limiting slot can also play a similar limiting and guiding role.

[0043] refer to Figures 1-3To further facilitate the movable connection between the connector 21 and the fixed plate 12, a first bolt hole 121 is provided at one end of the fixed plate 12 near the connector 21. Two first bolt holes 121 are spaced apart along the length of the fixed plate 12. A first elongated hole 212, which mates with the first bolt hole 121, is provided at one end of the connector 21 near the fixed plate 12. The length of the first elongated hole 212 is greater than the relative distance between any two points on the two first bolt holes 121. By passing a bolt through the first bolt hole 121 and the first elongated hole 212, the connector 21 can move horizontally relative to the fixed plate 12 within a certain range.

[0044] refer to Figures 1-3 The sliding component 22 includes a support plate 221 and a sliding block 222. The support plate 221 is configured to cooperate with the connecting component 21 and is perpendicular to the sliding block 222. Ribs are added between the support plate 221 and the sliding block 222 to enhance the structural strength of the sliding component 22. The sliding block 222 is concave to fit the steel column 3, and its shape matches the outer contour of the steel column 3, ensuring that the sliding block 222 fits tightly against the steel column 3. The sliding block 222 has a second bolt hole 2221, and the steel column 3 has a pre-fabricated second elongated hole 31. By passing bolts through the second bolt hole 2221 and the second elongated hole 31, the sliding component 22 can slide on the steel column 3. In some special applications, a roller-type sliding component 22 can be used to replace the existing sliding block 222 to reduce friction during sliding.

[0045] Specifically, one end of the connector 21 is movably connected to the fixed plate 12, and the other end is fixedly connected to the sliding member 22. When the elevator vibrates or displaces during operation, the connector 21 can move horizontally relative to the fixed plate 12, while the sliding member 22 can slide on the steel column 3. In this way, the entire connector 21 can adapt to certain displacement changes, avoiding damage to the connection parts caused by rigid connection. At the same time, the diamond-shaped connector 21 and the ribbed sliding member 22 together ensure the strength and stability of the second connecting assembly 2.

[0046] The implementation principle of the prefabricated elevator and the original concrete connection component in this application embodiment is as follows: the anchor plate 11 is fixedly installed on the existing building, the connector 21 is engaged with the rib plate 13 and the fixing plate 12, the bolt passes through the first bolt hole 121 and the first elongated hole 212, and the connector 21 can move horizontally relative to the fixing plate 12 within a certain range. The support plate 221 is bolted to the connector 21 to support the connector 21. The sliding block 222 engages with the shaft steel column 3. The sliding block 222 can slide on the steel column 3 by the bolt passing through the second bolt hole 2221 and the second elongated hole 31.

[0047] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
