Description

Technical Field

[0001] This utility model relates to the field of elevator shaft splicing technology, specifically to a splicing structure for the columns and beams of an elevator shaft. Background Technology

[0002] With the increasing number of villas and people's growing demands for quality of life, the demand for villa elevators is also increasing, which places higher requirements on the design of steel structure elevator frames.

[0003] Traditional steel structure hoists for villa elevators, while meeting some operational requirements, still have several significant drawbacks. Two prominent issues are structural complexity and exposed screws. Referring to a utility model patent application (202420164131.2) disclosing a steel structure hoist for a villa elevator, the connection between the column and beam components requires multiple parts and a complex assembly process. This complex design not only increases manufacturing difficulty and cost but also hinders the ease of installation and disassembly. For villa elevators, which require frequent maintenance and repair, this structural complexity undoubtedly increases the difficulty and workload of maintenance.

[0004] Furthermore, since the column and beam assemblies are typically fixed together with screws, these screws are susceptible to environmental factors such as corrosion and loosening during use, thus affecting the overall stability of the derrick. Additionally, exposed screws detract from the derrick's aesthetics and clash with the upscale interior design of the villa. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a column and beam splicing structure for elevator shafts.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An elevator shaft column and beam splicing structure includes: a hollow column body with a first assembly hole on it;

[0008] The hollow beam body has a second assembly hole at one end, which extends through the beam body from top to bottom.

[0009] The connector has a U-shaped structure, including a fixed side in the middle and positioning sides on both sides;

[0010] The fixed edge of the connector is fixed to the first assembly hole by bolts, and the two positioning edges of the connector are inserted from the end of the main body of the crossbeam. Two sets of bolts are passed through the second assembly holes on the upper and lower sides respectively and then connected and fixed to the two positioning edges, thereby forming a splice.

[0011] In this utility model, an installation port is provided on the inner side of the crossbeam body near the end, for inserting the nut into the interior of the crossbeam body through the installation port and tightening it with the bolt.

[0012] Furthermore, it also includes a cover plate that fits into the contour of the mounting opening, and a fixing block that fixes the cover plate. One end of the fixing block extends into the interior of the crossbeam body and is fixed by screws. The other end of the fixing block is located at the mounting opening. The cover plate is connected to the fixing block by screws to cover the mounting opening.

[0013] In this utility model, the first assembly hole and the second assembly hole are provided in two sets. The fixing edge of the connector is fixed on the two sets of the first assembly holes, and the two positioning edges of the connector are respectively fixed on the two sets of the second assembly holes on the upper and lower sides.

[0014] In this utility model, the first mounting hole extends horizontally through the column body. After the bolt passes through the fixing side of the connector and the first mounting hole on one side, it exits from the first mounting hole on the other side and is tightened with a nut. Alternatively, the bolt enters from the first mounting hole on one side, exits from the first mounting hole on the other side, passes through the fixing side, and is tightened with a nut.

[0015] In this utility model, the connection between the bolt and the positioning edge is that a group of bolts enters from the second mounting hole on the upper or lower side, passes through the two positioning edges inside, and then exits from the second mounting hole on the lower or upper side, and is tightened and fixed with the nut.

[0016] This utility model has the following advantages and beneficial effects:

[0017] This structure uses U-shaped connectors to achieve rapid assembly of the columns and beams, requiring fewer parts, simplifying the assembly process, and reducing manufacturing difficulty and cost. At the same time, this assembly method significantly reduces the number of exposed bolts, retaining only the necessary connecting bolts, greatly enhancing the aesthetics of the derrick and making it more harmonious with the high-end interior design of the villa.

[0018] Furthermore, this invention also considers ease of installation by providing an installation opening on the main body of the crossbeam. This allows for easy insertion of nuts into the crossbeam to engage with bolts and tighten, improving installation efficiency. Additionally, by incorporating a cover plate and fixing block that fit the contour of the installation opening, the opening is effectively covered after connection and fixation, maintaining the overall aesthetic appearance of the derrick.

However, this utility model is not limited to the following embodiments.

[0027] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0028] like Figures 1 to 4As shown, this embodiment discloses a column and beam splicing structure for an elevator shaft, including a hollow column body 1 and a beam body 2, and a connector 3 connecting the column body 1 and the beam body 2. The column body 1 is provided with a first mounting hole 10, and one end of the beam body 2 is provided with a second mounting hole 20. The first mounting hole 10 communicates with the interior of the column body 1, and the second mounting hole 20 penetrates the beam body 2 vertically. The connector 3 has a U-shaped structure, specifically including a fixed edge 31 located in the middle and positioning edges 32 located on both sides. The fixed edge 31 of the connector 3 is fixed to the first mounting hole 10 by bolts. The two positioning edges 32 of the connector 3 are inserted together from the end of the beam body 2. Then, two sets of bolts are passed through the second mounting holes 20 on the upper and lower sides respectively and connected and fixed to the positioning edges 32, thereby forming a splice. This splicing method does not require too many parts. The connection part only needs to be spliced ​​by the connector 3. At this time, only the bolts installed in the second mounting holes 20 are exposed. The structure is simple and greatly improves the aesthetics.

[0029] Furthermore, in order to ensure a stable connection between the two sets of bolts and the positioning edges 32 on both sides, the nuts and bolts need to be tightened inside the main body of the beam 2. Therefore, for ease of installation, an installation port 21 is provided on the inner side of the main body of the beam 2 near the end. The nuts can be inserted into the interior of the main body of the beam 2 through the installation port 21, improving convenience. In addition, after the main body of the beam 2 is connected and fixed to the connecting piece 3, the installation port 21 needs to be covered. Therefore, a cover plate 22 that fits into the contour of the installation port 21 and a fixing block 23 that fixes the cover plate 22 are also provided. First, one end of the fixing block 23 is inserted into the interior of the main body of the beam 2 and fixed with screws, while the other end of the fixing block 23 is located at the position of the installation port 21. The cover plate 22 is connected to the fixing block 23 with screws to cover the installation port 21.

[0030] Furthermore, in order to improve the connection stability of the connector 3, the first assembly hole 10 and the second assembly hole 20 are provided in two sets. The fixing edge 31 of the connector 3 is fixed on the two sets of the first assembly holes 10, and the two positioning edges 32 of the connector 3 are respectively fixed on the two sets of the second assembly holes 20 on the upper and lower sides.

[0031] Not limited to the above embodiments, such as Figure 5As shown, in order to further improve the connection stability, the first mounting hole 10 extends horizontally through the column body 1. At this time, the bolt passes through the fixing edge 31 of the connector 3 and the first mounting hole 10 on one side, and then exits from the first mounting hole 10 on the other side and is tightened with a nut. Alternatively, the bolt enters from the first mounting hole 10 on one side, exits from the first mounting hole 10 on the other side, passes through the fixing edge 31, and is tightened with a nut. Both methods only add a set of exposed screws after improving the connection stability, and still have a certain aesthetic appeal.

[0032] Not limited to the above embodiments, such as Figure 5 As shown, the bolt can also be connected to the positioning edge 32 by a set of bolts passing through the second mounting hole 20 on the upper or lower side, passing through the two positioning edges 32 inside, and then exiting from the second mounting hole 20 on the lower or upper side, and being tightened with a nut. This method can connect and fix the positioning edge 32 to the beam body 2 at one time, saving the use of bolts.

[0033] The above description in this specification is merely an illustrative example of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the specific embodiments described or adopt similar methods to replace them, as long as they do not deviate from the content of this specification or exceed the scope defined in the claims, they shall all fall within the protection scope of this invention.
