Description

Technical Field

[0001] The present invention relates to the technical field of processing and installing modular retrofit elevators, and in particular to a connection system between a modular retrofit elevator and 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 plates. 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. There is no operating space when the elevator module of the added elevator is connected to the original building structure, and the risk of high-altitude operations is relatively high.

[0089] The connection between the elevator module 2 and the structural beam 1 includes: installation and fixation between the elevator module 2 and the existing building, installing a first fixing member 4 and a second fixing member on the structural beam 1, fixing the first fixing member 4 to the first connecting member 3 of the elevator module 2, and fixing the second fixing member to the second connecting member of the elevator module 2.

[0090] Specifically, in S1, the location where the elevator is to be installed is first confirmed. If there is no elevator foundation, the elevator foundation form is determined based on the geological survey results, on-site conditions and calculation results, and a new elevator foundation is set up. If there is an elevator foundation, whether the original elevator foundation meets the requirements for installing the elevator is reviewed. If not, the elevator foundation is reinforced according to the calculation results.

[0091] Specifically, in S2, a new elevator foundation pit is added according to the foundation pit depth provided by the elevator manufacturer. The elevator foundation pit can be prefabricated in the factory or cast on site, and foundation embedded plates are set at the four corner points on the top of the elevator foundation pit.

[0092] Specifically, in S3, the opening and reinforcement of the structural beam 1 include: laying out lines to locate the target connection position of the elevator module 2 and the structural beam 1; if the original structural beam 1 meets the safety requirements after the elevator is installed, a first through hole 11 and a second through hole are opened at the target connection position; if the original structural beam 1 does not meet the safety requirements after the elevator is installed, the structural beam 1 is reinforced by a fiber cloth reinforcement method, and then a first through hole 11 and a second through hole are opened at the target connection position of the reinforced structural beam. Furthermore, the fiber cloth reinforcement method includes: first processing the surface of the structural beam 1 to ensure that it is flat and clean, and then reinforcing the structural beam 1 with a specified carbon fiber material.

[0093] like Figure 8 As shown, the column connecting member 6 includes a vertical connecting plate 61 and a horizontal connecting plate 62 .

[0094] For the installation of the first-floor elevator module 2, the first-floor column connector 6 only includes the half part above the horizontal connecting plate 62. The horizontal connecting plate 62 of the first-floor column connector 6 is welded to the embedded plate at the top of the elevator foundation pit. The elevator module 2 is hoisted, and the vertical connecting plate 61 of the first-floor column connector 6 is inserted into the column end through-hole at the bottom of the module column of the elevator module 2. Then, high-strength grouting material is poured through the grouting port 7 at the bottom end of the module column of the elevator module 2 to connect the elevator module 2 to the elevator foundation pit, completing the installation of the first-floor elevator module 2.

[0095] To fix the first-floor elevator module 2, install the first fixing member 4 and the second fixing member, place a first connecting bolt 43 in each first through hole 11, place the first connecting end plate 41 on the side of the structural beam 1 facing the elevator module 2, one end of the first connecting bolt 43 passes through the first connecting end plate hole 411 and is fixedly connected to the first connecting end plate 41 by through-hole plug welding, place the U-shaped first connecting gasket 45 between the first connecting end plate 41 and the structural beam 1 and weld it to the first connecting end plate 41, put the first pad 42 on the other end of the first connecting bolt 43, pass the first pad hole 421 and use two first connecting nuts 44 to tighten it.

[0096] Then pour high-strength grouting material into the U-shaped groove of the first connecting gasket 45 until the first through hole 11 and the U-shaped groove of the first connecting gasket 45 are filled. Finally, weld one end of the first connecting steel plate 5 to the first connecting beam 32, and weld the other end of the first connecting steel plate 5 to the first connecting end plate 41, thereby completing the connection between the first connecting member 3 and the first fixing member 4.

[0097] A second connecting bolt is placed in each second through hole, and the second connecting end plate is placed on the side of the structural beam 1 facing the elevator module 2. One end of the second connecting bolt passes through the second connecting end plate hole and is fixedly connected to the second connecting end plate by through-hole plug welding. A U-shaped second connecting gasket is placed between the second connecting end plate and the structural beam 1 and welded to the second connecting end plate. The second pad is sleeved on the other end of the second connecting bolt, and the second connecting bolt passes through the second pad hole and is tightened using two second connecting nuts.

[0098] Then pour high-strength grouting material into the U-shaped groove of the second connecting gasket until the second through hole and the U-shaped groove of the second connecting gasket are filled. Finally, weld one end of the second connecting steel plate to the second connecting beam, and weld the other end of the second connecting steel plate to the second connecting end plate to complete the connection between the second connecting piece and the second fixing piece, that is, complete the connection between the first-floor elevator module 2 and the structural beam 1.

[0099] The installation of the standard floor elevator module 2 begins with drilling and reinforcing the corresponding structural beam 1, similar to the drilling and reinforcement of the structural beam 1 in the above-mentioned first floor elevator module 2 installation steps, and a first through hole 11 and a second through hole are opened on the structural beam 1 of the corresponding floor.

[0100] Installation of elevator module 2, such as Figure 8 As shown, a column connector 6 is placed in the column end through-hole at the top of the elevator module 2 on the upper floor, and the module is leveled. The elevator module 2 is hoisted, and the vertical connecting plate 61 at the upper end of the column connector 6 is inserted into the column end through-hole at the bottom of the module column of the elevator module 2 on this floor. High-strength grouting material is then poured through the grouting port 7 at the bottom end of the module column of the elevator module 2 on this floor to connect the two vertically adjacent elevator modules 2 together, completing the installation of the standard floor elevator module 2.

[0101] The fixing of the elevator module 2 is the same as the fixing of the elevator module 2 in the above-mentioned first-floor elevator module 2 installation steps. The first fixing member 4 and the second fixing member are installed on the structural beam 1 of the corresponding floor, and high-strength grouting material is poured into the U-shaped groove of the first connecting gasket 45 and the second connecting gasket. The elevator module 2 is fixedly connected to the structural beam 1 by welding the first connecting steel plate 5 and the second connecting steel plate.

[0102] The installation steps of the standard floor elevator modules 2 are repeated as described above until all standard floor elevator modules 2 are installed.

[0103] Finally, a capping module is set on the upper part of the top elevator module 2. The four module columns of the capping module have column end through holes only at the bottom. The capping module and the upper standard elevator module 2 are fixedly connected by pouring high-strength grouting material through the column connector 6, and the installation of the elevator is completed.

[0104] In the above-mentioned renovation method of installing a modular elevator in an existing building, the first-floor elevator module 2 and the elevator foundation pit, as well as adjacent elevator modules 2, are connected together by four column connectors 4 arranged in the through holes at the ends of the four module columns.

[0105] like Figure 8 As shown, a plurality of through holes are provided on the surface of the horizontal connecting plate 62 of the column connector 6 to connect the column end through holes between the module columns of adjacent elevator modules 2. A plurality of steel bars 63 are also provided on the surface of the vertical connecting member 61 of the column connector 6 to assist the column connector 6 in achieving an anti-pullout effect.

[0106] A grouting port 8 is also provided above the grouting port 7 on the side wall at the bottom end of the four module columns of each elevator module 2. The grouting port 7 and the grouting port 8 are both connected to the column end through-hole at the bottom end of the elevator module 2. When high-strength grouting material is poured into the grouting port 7, until the high-strength grouting material overflows from the grouting port 8, it indicates that the column end through-hole has been filled.

[0107] The modular elevator installation and connection system of the present invention with the existing building does not require planting reinforcement on the outside of the building wall structure. The connection between the structural beam 1 and the elevator module 2 is simple and the construction is convenient. After the elevator module 2 on each floor is connected to the original building structure, the installation operation of the elevator module 2 on the next floor can be carried out.
