Description

Technical Field

[0001] The present invention relates to the technical field of processing and installing modular retrofitted elevators, and in particular to a connection system between a modular retrofitted elevator and an overhead floor of an existing building. Background Art

[0002] The earlier buildings built in the last century usually only had stairs and no elevators installed, which caused great trouble to the lives and work of the residents upstairs. As the aging population became more and more serious, the interference with the lives and work of the residents became more and more serious. With the advancement of the old house renovation project, adding elevators to old buildings has become a more important task and one of the important manifestations of improving residents' living conditions.

[0003] Modular retrofit elevators are currently a more common type of retrofit elevator because they are split into multiple modules and prefabricated in the factory. The modules are easy to lift, transport and install as a whole. Elevator modules mostly use steel structures and are assembled to form an elevator shaft. The lower part of the elevator shaft is fixed to the cast ground, and the elevator modules are fixed to the building wall structure through connectors, so that the elevator shaft is overlapped and fixed to the outside of the building wall.

[0004] In the existing technology, the connection between the elevator module of the added elevator and the building wall structure mostly adopts the external embedded reinforcement and embedded plate. During construction, it is necessary to embed reinforcement on the outside of the building wall structure. This connection form is complicated and inconvenient to construct. In addition, for high-rise buildings with an elevated floor on the roof, there are no structural plates around the structural beams of the elevated floor. There is no operating space when the elevator module of the added elevator is connected to the elevated floor of the original building structure, and the risk of high-altitude operations is relatively high. Summary of the Invention

[0005] (1) Technical issues to be solved

[0006] In order to solve the above-mentioned problems of the prior art, the present invention provides a modular connection system for adding elevators to the elevated floors of existing buildings, so as to solve the problems of complex connection between the elevated beams of the original building structure and the elevator modules, lack of an on-site operating surface, inconvenient high-altitude construction and high risk.

[0007] (2) Technical solution

[0008] In order to achieve the above objectives, the main technical solutions adopted by the present invention are:

[0009] A system for connecting a modular elevator to an overhead floor of an existing building, comprising an overhead beam, an elevator module, and a first connecting assembly and a second connecting assembly connecting the overhead beam and the elevator module;

[0010] The first connecting assembly includes: a first connecting member, a first connecting hoop and a supporting member;

[0011] The second connecting assembly includes: a second connecting piece and a second connecting hoop;

[0012] The first connecting member, the second connecting member and the supporting member are all arranged on the outer side of the elevator module close to the overhead beam;

[0013] The first connecting hoop and the second connecting hoop are both sleeved on the outer surface of the overhead beam, the first connecting piece is fixedly connected to the first connecting hoop, and the second connecting piece is fixedly connected to the second connecting hoop.

[0014] The modular elevator installation system of the present invention is connected to the overhead layer of the existing building. The overhead beam and the elevator module are connected together by a first connecting component and a second connecting component. The first connecting clamp of the first connecting component and the second connecting clamp of the second connecting component are sleeved on the outer surface of the overhead beam. This arrangement does not require planting reinforcement from the outside of the building, nor does it require drilling from the inside of the building.

The connection system of the present invention can use the elevator module as an operating platform after the elevator module is set up, and the elevator module and the overhead beam can be connected on the elevator module. Compared with the traditional connection form of external planting reinforcement plus embedded plates, operators do not need to suspend at high altitude to perform the operation, which reduces the risk of the operation, facilitates construction, and is safe and reliable.

[0024] The modular elevator of the present invention is connected to the overhead floor of an existing building through a system in which the first connecting beam of the first connecting member is used to connect the elevator module and the first connecting hoop sleeved on the outer surface of the overhead beam. The first connecting beam and the first connecting hoop are welded together through a first connecting steel plate. A reinforcing brace is also welded to one side of the first connecting beam. The reinforcing brace is welded to the first connecting beam and the elevator module, so that the first connecting component forms a triangular structure. At the same time, the extension direction of the first connecting beam is consistent with the length extension direction of the second module beam of the elevator module, which can improve the stability of the connection.

[0025] Preferably, the second connecting member includes a second reinforcing plate and a second connecting beam;

[0030] Preferably, the first connecting beam, the second connecting beam, the node plate, the reinforcing brace, the first connecting steel plate and the second connecting steel plate are on the same horizontal plane.

[0031] The second connecting beam of the second connecting member of the present application is parallel to the first connecting beam of the first connecting member, and the first connecting beam, the second connecting beam, the node plate, the reinforcing brace, the first connecting steel plate and the second connecting steel plate are on the same horizontal plane, which can improve the stability of the overhead beam after being connected to the elevator module.

[0032] Preferably, a first gasket is further provided on the inner wall surface of the first connecting hoop, and a second gasket is further provided on the inner wall surface of the second connecting hoop.

[0033] Gaskets are provided on the inner wall surfaces of the first connecting hoop and the second connecting hoop. When the first connecting end plate and the first C-shaped hoop are welded together and the second connecting end plate and the second C-shaped hoop are welded together, the first connecting hoop and the second connecting hoop do not directly contact the overhead beam, which can not only enable the first connecting hoop and the second connecting hoop to tightly hold the overhead beam, but also prevent the overhead beam from being squeezed and damaged when welding the first connecting hoop and the second connecting hoop.

[0034] (3) Beneficial effects

[0035] Beneficial effects of the present invention:

[0036] Compared with the traditional connection form of external embedded reinforcement and embedded plates, the modular connection system of the present invention with the overhead beam of the building is prepared in advance in the factory and integrated on the elevator module. Only simple welding is required on site to complete the connection between the overhead beam and the elevator module. The connection structure does not require embedded reinforcement from the outside of the building, nor does it require drilling from the inside of the building. At the same time, after the elevator module is set up, the elevator module can be used as an operating platform, and the welding construction work of the elevator module and the overhead beam can be carried out on the elevator module, avoiding high-altitude hanging operations of personnel. The construction is convenient, safe and reliable, reducing the risks brought by on-site construction operations, and reducing the impact of construction on the normal lives of residents.

[0051] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 2 Specifically, the interior of the elevator module is defined as the "inside" and the exterior of the elevator module is defined as the "outside".

[0052] Example

[0053] like Figure 1-Figure 5 As shown, the connection system of the modular additional elevator and the overhead floor of an existing building of the present invention includes an overhead beam 1, an elevator module 2, and a first connecting component and a second connecting component connecting the overhead beam 1 and the elevator module 2. The first connecting component includes a first connecting member 3, a first connecting hoop and a support member, and the second connecting component includes a second connecting member and a second connecting hoop. The first connecting member 3, the second connecting member and the support member are all arranged on the outer side of the elevator module 2 close to the overhead beam 1, and the first connecting hoop 4 and the second connecting hoop are both sleeved on the outer surface of the overhead beam 1. The first connecting member 3 is fixedly connected to the first connecting hoop 4, and the second connecting member is fixedly connected to the second connecting hoop. The first connecting component and the second connecting component fixedly connect the overhead beam 1 and the elevator module 2 together.

[0054] The elevator module 2 of the present invention is a steel structure. The installed elevator includes multiple elevator modules 2. Each elevator module 2 includes an upper beam frame and a lower beam frame. The corresponding corners of the upper beam frame and the lower beam frame are fixedly connected by four module columns to form a rectangular frame structure; the elevator module 2 of the installed elevator is connected to the overhead beam 1 of the building's overhead layer through a first connecting component and a second connecting component.

[0055] like Figure 2 and Figure 3As shown, the upper beam frame includes a first module beam 22 located between a first module column 21 and a second module column 23 , a first connecting assembly is arranged at one end of the first module beam 22 close to the first module column 21 , and a second connecting assembly is arranged on the second module column 23 .

[0056] In the first connecting assembly, the first connecting member 3 includes a first reinforcing plate 31 and a first connecting beam 32. The first reinforcing plate 31 is welded to the side of the first modular beam 22 facing the overhead beam 1 and is flush with the first modular beam 22. The first connecting beam 32 is an I-beam, one end of which is welded to the first reinforcing plate 31 and extends in the same direction as the second modular beam 24. The supporting member includes a gusset plate 33 and a reinforcing brace 34. The gusset plate 33 is a special-shaped steel plate welded at the beam-column connection between the first modular column 21 and the first modular beam 22. The gusset plate 33 is horizontally arranged and at the same height as the first connecting beam 32. The reinforcing brace 34 is a channel steel, one end of which is welded to the gusset plate 33 and the other end is welded to the side wall of the first connecting beam 32. The first connecting beam 32, the first modular beam 22, and the reinforcing brace 34 form a triangular structure, which enhances the stability of the first connecting assembly.

[0057] like Figure 3 and Figure 4 As shown, the first connecting hoop 4 includes a first C-shaped hoop 41 and a first connecting end plate 42. The first connecting end plate 42 is welded to the opening of the first C-shaped hoop 41 to form a closed whole that is sleeved on the outer surface of the overhead beam 1. The first connecting end plate 42 of the closed whole faces the elevator module 2. The first connecting end plate 42 is welded to the first connecting beam 32 through the first connecting steel plate 5; one end of the first connecting steel plate 5 is welded to the first connecting end plate 42, and the other end of the first connecting steel plate 5 is welded to the first connecting beam 32.

[0058] In the second connecting assembly, the second connecting member includes a second reinforcing plate and a second connecting beam. The second reinforcing plate is welded on the side of the second module column 23 facing the overhead beam 1. The second connecting beam is an I-beam. One end of the second connecting beam is welded to the second reinforcing plate and the second connecting beam is arranged parallel to the first connecting beam 32 at the same height.

[0059] The second connecting hoop has the same structure as the first connecting hoop 4, including a second C-shaped hoop and a second connecting end plate. The second connecting end plate and the opening of the second C-shaped hoop are welded to form a closed whole that is sleeved on the outer surface of the overhead beam 1. The second connecting end plate of the closed whole faces the elevator module 2, and the second connecting end plate is welded to the second connecting beam through the second connecting steel plate; one end of the second connecting steel plate is welded to the second connecting end plate, and the other end of the second connecting steel plate is welded to the second connecting beam.

[0060] Preferably, the first connecting beam 32 , the second connecting beam, the node plate 33 , the reinforcing brace 34 , the first connecting steel plate 5 and the second connecting steel plate are on the same horizontal plane.

[0061] The above design can ensure that the first connecting component and the second connecting component are evenly stressed after being connected, thereby improving the stability of the structure and ensuring that the elevator module 2 is stable and firm.

[0062] A first gasket 43 is also provided on the inner wall surface of the first connecting hoop 4, and a second gasket is also provided on the inner wall surface of the second connecting hoop. The first gasket 43 and the second gasket have the same structure. The first connecting hoop 4 and the second connecting hoop are both sleeved on the outer surface of the overhead beam 1. When the first connecting end plate 42 is welded to the first C-shaped hoop 41 and the second connecting end plate is welded to the second C-shaped hoop, the first gasket 43 and the second gasket can make the first connecting hoop 4 and the second connecting hoop tightly hold the overhead beam 1. At the same time, the first connecting hoop 4 and the second connecting hoop do not directly contact the overhead beam 1, and can also prevent the overhead beam 1 from being squeezed and damaged when welding the first connecting hoop 4 and the second connecting hoop.

[0063] The first connecting member 3, the supporting member and the second connecting member of the present invention are all prefabricated and welded to the elevator module 2 in advance in the factory. After being transported to the site and the installation of the elevator module 2 is completed, it is only necessary to install the first connecting clamp 4 and the second connecting clamp on the outer surface of the overhead beam 1, and then weld the first connecting member 3 and the first connecting clamp 4 through the first connecting steel plate 5, and weld the second connecting member and the second connecting clamp together through the second connecting steel plate to complete the connection between the elevator module 2 and the overhead beam 1.

[0064] The connection system of the modular additional elevator and the overhead layer of an existing building of the present invention is used for connecting the modular additional elevator and the overhead layer of a building structure. It is different from the connection structure of the modular additional elevator and the residential layer of a building structure. The first connection clamp 4 and the second connection clamp of the clamp type connection system need to be sleeved on the outer surface of the independent overhead beam 1, which is suitable for connecting the modular additional elevator and the overhead beam 1 of the overhead layer of the building structure. When the modular additional elevator is installed, an elevator module 2 on the top floor is connected to the overhead beam 1 of the overhead layer of the building structure.

[0065] The installation process of the connection system between the modular additional elevator and the overhead layer of an existing building of the present invention is as follows: first, a first gasket 43 is sleeved on the outer surface of the overhead beam 1, and the first C-shaped hoop 41 is installed on the overhead beam 1, and then the first connecting end plate 42 is welded to the first C-shaped hoop 41, so that the first connecting hoop 4 holds the overhead beam 1 tightly, and then the first connecting steel plate 5 is welded between the first connecting end plate 42 and the first connecting beam 32. The first connecting steel plate 5 is arranged horizontally, one end of the first connecting steel plate 5 is welded to the first connecting beam 32, and the other end is welded to the first connecting end plate 42, and the connection between the elevator module 2 and the overhead beam 1 is completed; the installation of the second connecting hoop and the second connecting beam is the same as the installation of the first connecting hoop 4 and the first connecting beam 32 mentioned above.

[0066] The modular installation elevator and the connection system of the existing building overhead layer of the present invention, the first connecting member 3 of the first connecting assembly, the support member and the second connecting member of the second connecting assembly are all pre-installed on the elevator module 2 in the factory. During on-site construction, the construction personnel only need to install the first connecting clamp 4 and the second connecting clamp, and then simply weld the first connecting steel plate 5 and the second connecting steel plate. This connection system does not require planting reinforcement on the overhead beam 1, nor does it require drilling. At the same time, after the elevator module 2 is set up, the elevator module 2 can be used as an operating platform, and the elevator module 2 and the overhead beam 1 can be welded on the elevator module 2, avoiding high-altitude hanging operations. The construction is convenient, safe and reliable, reduces the risks brought by on-site construction operations, and reduces the impact of construction on the normal lives of residents.

These descriptions are intended solely to illustrate the principles of the present invention and are not to be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific embodiments of the present invention without inventive effort, and such embodiments will fall within the scope of protection of the present invention.
