Description

Technical Field

[0001] The present invention relates to the technical field of elevators, and in particular to a thin-wall light steel multi-cavity plate elevator shaft and a manufacturing method thereof. Background Art

[0002] With the acceleration of urbanization and the improvement of people's living standards, the renovation and upgrading of old residential areas has become an important issue in urban development. One of the most common problems in old residential areas is the lack of elevators, which has brought great inconvenience to the lives of residents. Installing elevators is an important part of the renovation of old residential areas. It is not only related to the convenience of residents' daily life, but also an important force to promote the development of the community and even the entire city.

[0003] The elevator shaft is an important part of the elevator system. It provides a closed space for the operation of the elevator, which not only ensures the safe operation of the elevator, but also supports the installation and maintenance of elevator equipment, optimizes the utilization of building space, improves the aesthetics of the building, and enhances the fire resistance of the building.

[0004] Traditional elevator shafts are usually made of reinforced concrete or steel structures. Although these two types of elevator shafts have their own characteristics, they both have disadvantages such as heavy weight, high construction cost, great manufacturing difficulty, long construction period, and low insulation and noise reduction level. These disadvantages have caused great negative impacts on nearby residents, especially residents of old communities, during the construction and operation of the entire elevator shaft. Summary of the invention

[0005] The object of the present invention is to provide a thin-wall light steel multi-cavity plate elevator shaft and a manufacturing method thereof, which helps to solve the above-mentioned technical problems.

[0006] The present invention is achieved in that:

[0007] A thin-walled light steel multi-cavity plate elevator shaft comprises N cylindrical shaft walls and N-1 connecting pieces, wherein N is a positive integer; the cylindrical shaft walls are formed by bending and rolling thin-walled light steel multi-cavity plates; two adjacent cylindrical shaft walls are fixedly spliced ​​along their own axial direction by the connecting pieces.

[0008] Furthermore, the plate cavity of the cylindrical well wall is in the shape of a long strip; the length direction of the plate cavity is parallel to the axial direction of the cylindrical well wall. The technical effect is that the bending and rolling method can improve the thermal insulation, sound insulation and noise reduction performance of the cylindrical well wall while maintaining the mechanical strength of the cylindrical well wall as much as possible.

[0009] Furthermore, the plate cavity of the cylindrical well wall is in the shape of a long strip; the length direction of the plate cavity is perpendicular to the axial direction of the cylindrical well wall. The technical effect is that the bending and rolling method can improve the mechanical strength of the cylindrical well wall while maintaining the thermal insulation, sound insulation and noise reduction performance of the cylindrical well wall as much as possible.

[0010] Furthermore, the cylindrical shaft wall is provided with a pre-installed channel and / or a pre-installed window. The technical effect is that the pre-installed channel is used to meet the installation space requirements of the elevator shaft such as ventilation and circuits, and the pre-installed window is used to meet the design requirements of the elevator shaft such as lighting and advertising.

[0011] Furthermore, the connecting piece includes an H-shaped steel and a bolt; two adjacent cylindrical shaft walls are relatively inserted into the H-shaped steel and abut against the web of the H-shaped steel, and the bolt penetrates the cylindrical shaft wall and the flanges on both sides of the H-shaped steel. The technical effect is that the H-shaped steel and the bolt can fix and assemble the two adjacent cylindrical shaft walls, and the elevator shaft has the function of being detachable and reusable.

[0012] Furthermore, the connector also includes a limiting sleeve; the limiting sleeve is sleeved outside the bolt and respectively abuts against the inner wall of the flanges on both sides of the H-shaped steel. The technical effect is that the limiting sleeve makes the cylindrical well wall have a uniform installation thickness and improves the mechanical strength of the connection between the connector and the cylindrical well wall.

[0013] Furthermore, it also includes a top plate and an HL-shaped frame; the top plate is connected to the top of the cylindrical shaft wall on the upper side of the elevator shaft through the HL-shaped frame. Its technical effect is that the top plate and the HL-shaped frame realize the closed installation of the top of the elevator shaft, wherein the top plate is also preferably made of thin-walled light steel multi-cavity plate by bending and rolling.

[0014] Furthermore, it also includes a U-shaped base; the U-shaped base is fixedly connected to the bottom of the cylindrical shaft wall at the lower side of the elevator shaft. The technical effect is that the U-shaped base ensures that the elevator shaft has a neat and stable installation bottom, and improves the overall installation stability.

[0015] A method for manufacturing a thin-wall light steel multi-cavity plate elevator shaft comprises the following steps: S1, prefabricating a cylindrical shaft wall and connecting parts that meet size requirements in a production workshop; S2, assembling and forming the cylindrical shaft wall and connecting parts at a construction site.

[0016] Furthermore, in step S1, a pre-installed channel and / or a pre-installed window are also provided on the cylindrical shaft wall. The technical effect is that the pre-installed channel and / or the pre-installed window not only improves the convenience of using the elevator shaft, but also greatly improves the construction efficiency of the elevator shaft.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The thin-walled light steel multi-cavity plate elevator shaft and the manufacturing method thereof of the present invention utilize connectors to splice and assemble multiple cylindrical shaft walls, and the cylindrical shaft walls are formed by bending and rolling thin-walled light steel multi-cavity plates. The cylindrical shaft walls and connectors can be pre-fabricated in a workshop and quickly assembled on site. Compared with traditional reinforced concrete shafts or steel structure shafts, the shaft weight is reduced, the construction cost is reduced, the construction period is shortened, the manufacturing difficulty is reduced, the thermal insulation, sound insulation and noise reduction levels are improved, and the impact on residents during construction and operation is reduced.

[0031] It should be noted that the cylindrical shaft wall 100 is used to form the side wall of the elevator shaft, and the connector 200 is used to achieve fixed connection and installation of adjacent cylindrical shaft walls 100. This assembly method enables all components and parts of the elevator shaft to be manufactured in the production workshop, and only the manufactured cylindrical shaft wall 100 and connector 200 that meet the design size requirements and quantity requirements need to be transported to the construction site to complete the installation. At this time, the cylindrical shaft wall 100 and connector 200 that are fixedly connected and installed can also be disassembled and reused, further improving the reuse rate of the elevator shaft.

[0032] Compared with the traditional reinforced concrete shaft or steel structure shaft, the thin-walled light steel multi-cavity plate elevator shaft of this embodiment has a plate cavity composed of multiple cavities, which has the advantages of light weight, high strength, good thermal insulation and sound insulation performance, etc., which improves the thermal insulation, sound insulation and noise reduction level of the elevator shaft, reduces the dead weight of the elevator shaft, and makes the transportation and installation cost of the elevator shaft lower; and the modular assembly method of production workshop production and on-site installation greatly shortens the construction period of the elevator shaft, reduces the manufacturing difficulty and construction cost of the elevator shaft, reduces the workload and environmental pollution of on-site construction, and reduces the negative impact on nearby residents, especially residents of old communities, during construction and operation. It is particularly suitable for use scenarios such as installing elevators in existing buildings.

[0033] In addition, the design of thin-walled light steel multi-cavity panels can be customized according to different elevator specifications and building requirements to meet diverse needs.

[0034] The design of the connection method between two adjacent cylindrical shaft walls 100 takes into account the vibration and impact force during the operation of the elevator, thereby ensuring the safety and reliability of the elevator shaft.

In this embodiment, the H-shaped steel 210 and the bolt 220 fix and assemble the two adjacent cylindrical shaft walls 100, and make the elevator shaft detachable and reusable. Among them, the bolt 220 is preferably made of high-strength material.
