[0002] Adding elevator shafts to existing buildings typically involves using steel structure shafts, which are traditionally divided into two types: spliced ​​and segmented. The former involves on-site fabrication of the steel structure, where various components are welded together to form the overall shaft. The latter involves dividing the steel structure into multiple sections, which are manufactured in a factory and then transported to the site for assembly. Traditionally, segmented steel structure shafts rely heavily on on-site welding, which suffers from poor welding conditions and inconsistent weld quality. Currently, there is a need to develop a new shaft connection structure to facilitate the connection between upper and lower shaft modules, reducing the difficulty of this connection. Furthermore, there is a need to develop a shaft structure incorporating this new connection structure to improve installation efficiency. Utility Model Content

[0034] Combination Figures 1 to 9 To be understood, in one embodiment, a shaft structure also includes bolts; The lower section shaft module 41 has a set column D with a third connecting hole on its side. The third connecting hole is used to connect with the lower first threaded hole 111 of the connecting sleeve 1. The column D of the lower section shaft module 41 is a hollow square cross-section column.

Then, the lower section shaft module 41 and the second connector 3 are connected together using the bolt. The fourth connecting hole 412 can be a threaded hole or a circular through hole. Preferably, the fourth connecting hole 412 is a threaded hole.

[0036] After the connecting sleeve 1 and the second connecting piece 3 are installed on the set column D of the lower section shaft module 41, the upper section shaft module 42 is hoisted above the lower section shaft module 41, so that each column D of the upper section shaft module 42 is assembled with the corresponding column D of the lower section shaft module 41.

[0037] The upper shaft module 42 has a setting column D with a fifth connecting hole on its side, which is used to connect with the upper first threaded hole 112 of the connecting sleeve 1; the upper shaft module 42 has a setting column D with a sixth connecting hole 422 on its side, which is used to connect with the upper third threaded hole 312 of the second connecting piece 3. The column D of the upper shaft module 42 is a hollow square cross-section column; the setting column D of the upper shaft module 42 is fitted into the connecting sleeve 1, and the connecting sleeve 1 is located in the setting column D of the upper shaft module 42; the setting column D of the upper shaft module 42 is fitted into the second connecting member 3, and the second connecting member 3 is located in the setting column D of the upper shaft module 42. Next, adjust the upper section of the wellbore module 42 so that the fifth connecting hole is aligned with the upper first threaded hole 112 and the sixth connecting hole 422 is aligned with the upper third threaded hole 312. Then, use bolts to connect the upper section of the wellbore module 42 and the connecting sleeve 1 together, and connect the upper section of the wellbore module 42 and the second connecting piece 3 together.

[0038] After the upper section of the hoistway module 42 is connected to the connecting sleeve 1 and the second connecting piece 3, bolts are used to connect the second connecting hole 421 on the ring beam of the upper section of the hoistway module 42 and the first connecting hole 411 on the ring beam of the lower section of the hoistway module 41. Preferably, the first connecting hole 411 and the second connecting hole 421 are both threaded holes. However, in another embodiment, the first connecting hole 411 and the second connecting hole 421 are both through holes. The hoistway structure also includes a nut. The ring beam of the upper section of the hoistway module 42 and the ring beam of the lower section of the hoistway module 41 are connected as follows: after the bolt passes through the second connecting hole 421 and the first connecting hole 411, a nut is used to thread one end of the bolt, locking the end of the bolt that is prone to loosening, thereby tightly connecting the ring beam of the upper section of the hoistway module 42 and the ring beam of the lower section of the hoistway module 41 together.

[0039] Preferably, after the upper section shaft module 42 and the lower section shaft module 41 are connected, the lower end of the column of the upper section shaft module 42 and the upper end of the column of the lower section shaft module 41 are just joined together.

[0040] Preferably, both the lower section shaft module 41 and the upper section shaft module 42 of this utility model are steel structure shaft modules. A shaft module of this utility model refers to a section of shaft steel frame with a predetermined height.

[0041] Combination Figures 1 to 9 To understand this, in one embodiment, the installation sequence of a shaft structure is as follows: S1. The first connector 2 is obliquely welded to the set column D of the lower section shaft module 41 (wherein, the welding can be performed in the factory); the lifting hole 21 of the first connector 2 is conducive to the lifting of the lower section shaft module 41, that is, it is conducive to the lower section shaft module 41 to be moved to a different position by lifting. S2, connecting sleeve 1 and second connecting piece 3 are respectively connected to the set column D of the lower section wellbore module 41 by bolts; if the lower section wellbore module 41 needs to be moved, a lifting piece can be added to the second threaded hole 12 of the connecting sleeve 1. The threaded part of the lifting piece is threadedly connected to the second threaded hole 12. After the lifting piece is installed, the lifting piece, together with the first connecting piece 2, facilitates the lifting of the lower section wellbore module 41, that is, facilitates the relocation of the lower section wellbore module 41 by lifting; combined with Figure 5 For understanding purposes, preferably, the lower shaft module 41 has two columns D on one diagonal line when viewed from above, each equipped with a connecting sleeve 1; the lower shaft module 41 has two columns D on the other diagonal line when viewed from above, each equipped with a "first connector 2 and a second connector 3". S3. Hoist the upper section of the shaft module 42, so that the setting column D of the upper section of the shaft module 42 is fitted onto the connecting sleeve 1, and the setting column D of the upper section of the shaft module 42 is fitted onto the second connecting piece 3. The upper section of the wellbore module 42 is fastened to the connecting sleeve 1 and the upper section of the wellbore module 42 is fastened to the second connecting piece 3 by bolts. Finally, use bolts to connect the second connecting hole 421 on the ring beam of the upper section shaft module 42 and the first connecting hole 411 on the ring beam of the lower section shaft module 41, thus completing the assembly of the upper section shaft module 42 and the lower section shaft module 41.

[0042] After the upper section shaft module 42 and the lower section shaft module 41 are assembled, the first connector 2 is located in the column D of the shaft structure as a permanent structure; after the upper section shaft module 42 and the lower section shaft module 41 are assembled, the second connector 3 can improve the shear resistance at the connection between the upper section shaft module 42 and the lower section shaft module 41.

[0043] Among them, the terms "upper section hoistway module 42" and "lower section hoistway module 41" are relative. For example, if there is a hoistway module above the upper section hoistway module 42, then the upper section hoistway module 42 will become the "lower section hoistway module" relative to the hoistway module above it, and the original lower section hoistway module will become the "next-lower section hoistway module".

[0044] In this utility model, the upper section shaft module 42 and the lower section shaft module 41 are connected by "connecting sleeve 1, second connecting piece 3 and bolts". On-site assembly does not require welding, thus avoiding the problem of poor on-site welding conditions and the problem of poor welding quality that exists in on-site welding.

[0045] The shaft connection structure described in this utility model and other aspects of the shaft structure are described in the prior art and will not be repeated here.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
