One end of corridor 2 is built in the outside of old building, the other end is fixedly connected with modular elevator shaft monomer 1, and corridor 2 is tractionally connected between old building by connecting assembly 43, and the load capacity in horizontal direction that corridor 2 bears is transmitted to the side of elevator shaft through corridor 2, and vertical force is released in vertical direction.
[0038] When pedestrian walks from corridor 2, corridor 2 is subjected to vertical load, and has relative motion tendency between connecting seat A 41 and connecting seat B 42, and connecting seat A 41 and connecting seat B 42 are tractionally connected by connecting assembly 43, so as to transmit the load on corridor 2 to the side of elevator shaft and release vertical force. Compared with prior art, the corridor 2 is connected with the fixed bottom plate outside the building body, and the building body is acted vertically downward, so that the building body shares excessive load. The technical scheme of the present application solves the problem that the load in horizontal direction on the connection between old building and corridor 2 is too large, which easily damages the structure of old building in long-term use.
[0039] As Figures 3-6As shown, as a further solution of the present embodiment, the connecting assembly 43 comprises a bolt 46 for connecting the connecting seat A 41 with the connecting seat B 42, and a first sliding member 431 for reducing the interaction force between the connecting seat A 41 and the connecting seat B 42, and a second sliding member 432 for reducing the interaction force between the connecting seat B 42 and the bolt 46. In addition, the first sliding member 431 and the second sliding member 432 are made of polytetrafluoroethylene material, and the first sliding member 431 and the second sliding member 432 are in a plate structure, so that the friction coefficient of the contact surface between the connecting seat A 41 and the connecting seat B 42 and between the connecting seat B 42 and the bolt 46 is less than 0.01. Therefore, the first sliding member 431 and the second sliding member 432 are in smooth contact with the connecting seat A 41 on both sides and the connecting seat B 42 and the bolt 46. One end of the bolt 46 is relatively fixedly connected with the connecting seat A 41, and the other end is relatively movably connected with the connecting seat B 42 through the second sliding member 432. When the connecting seat A 41 and the connecting seat B 42 have a relative motion tendency, the load bearing force of the corridor 2 is transmitted to the vertical force release of the modular elevator shaft monomer 1 through the cooperation between the connecting assembly 43, so that the elevator shaft structure is safe and reliable, and has a long service life.
[0040] The connecting seat B 42 and the fixed steel plate are provided with a plurality of steel corbels 5 for reinforcement, and the steel corbels 5 are arranged at intervals with the bolt 46. Similarly, the connecting seat A 41 and the steel beam 21 are provided with steel corbels 5 on the side opposite to the connecting seat B 42. The steel corbels 5 can reinforce the connecting structure between the connecting seat A 41 and the steel beam 21 and between the connecting seat B 42 and the old building, have high bearing capacity and stability, and improve the long-term durability of the structure of the connecting seat A 41 and the connecting seat B 42.

The bolt 46 is connected through the connecting seat A 41 and the connecting seat B 42, and the strip-shaped hole 411 on the connecting seat B 42 is vertically arranged. The first sliding piece 431 is arranged between the connecting seat A 41 and the connecting seat B 42 to make the two smooth contact, and the second sliding piece 432 is also arranged between the connecting seat B 42 and the bolt 46 to make the two smooth contact, and the connecting seat A 41 can work in the vertical direction relative to the connecting seat B 42. When the corridor 2 is subjected to the bearing force in the vertical direction, the connecting seat A 41 and the connecting seat B 42 have a relative motion tendency after being subjected to the force, the connecting seat B 42 on the old building pulls the connecting seat A 41 and is not subjected to the bearing force of the corridor 2, but transmits the bearing force of the corridor 2 to the side of the elevator shaft through the cooperation of the connecting assembly 43, the strip-shaped hole 411 and the circular hole 421, and releases the vertical force, which is simple and reliable in structure.

Because the second sliding piece 432 and the bolt 46 are constantly rubbed during the working process, the second sliding piece 432 is prone to wear after long-term use, and therefore the pad 433 is arranged between the second sliding piece 432 and the bolt 46 to reduce the wear of the second sliding piece and prolong the service life. In order to ensure the reliability and safety of the connecting structure, the technician can arrange a plurality of bolts 46 to increase the connecting performance of the bolt 46 and the connecting seat B 42. The present technical scheme cooperates through the strip-shaped hole 411 and the first sliding piece 431 and the second sliding piece 432, which is convenient to install, safe and reliable in structure, and low in manufacturing cost.

The outer side of the old building is provided with a first fixed steel plate 44 connected with the connecting seat A41, and the inner side of the old building is fixed with a second fixed steel plate 45, and the anchoring assembly 11 penetrates the old building and fixedly connects the first fixed steel plate 44 and the second fixed steel plate 45 on both sides of the old building, so that the stress condition of the bearing capacity of the connecting seat B42 and the old building changes from point connection to surface connection. The first fixed steel plate 44 and the connecting seat B42 can be integrally formed during production to facilitate manufacturing, or a split type is adopted to fixedly connect the first fixed steel plate 44 and the connecting seat B42 at the construction site and welded to the old building to reduce packaging costs and cooperate with other structures to adapt to the actual installation conditions of different old buildings. Compared with the expansion bolts 46 used in the prior art to hard connect the corridor 2 and the old building, the expansion bolts are not very reliable, and if the load has a large vibration, it may come loose, and the settlement and aging of the old building with a long service life will be accelerated. In the present application, the anchoring assembly 11 is combined with the first fixed steel plate 44 and the second fixed steel plate 45 to change the stress condition of the bearing capacity of the connecting seat B42 and the old building from point connection to surface connection, so that the old building has a large horizontal bearing capacity, thereby fixedly connecting the connecting seat B42 on the outer side of the old building, and the structure is safe and reliable, and the construction is simple.
[0044] As shown in Figure 1 , Figure 2 As shown, as a further scheme of the present embodiment, in order to better transmit the bearing capacity on the corridor 2 to the elevator shaft, an inclined suspender 6 for transmitting vertical force to one side of the elevator shaft is arranged between the corridor 2 and the modular elevator shaft monomer 1. The corridor prefabricated slab 22 is welded with the steel column 3, and the end of the corridor prefabricated slab 22 close to the old building does not directly contact the old building. The connecting seat A41 is welded and fixed with the steel beam 21 and does not interfere with the corridor prefabricated slab 22. The technical scheme can reduce the bearing capacity on the corridor 2 and increase the service life of the old building.
[0045] During construction, the construction personnel installs temporary steel corbels (not shown in the figure) during the construction of the added elevator and the outer contour of the old building. First, the anchoring bolts 46 are installed between the corridor 2 and the old building, the first fixed steel plate 44 is welded and connected with the connecting seat B42 on the outer side of the old building, and the second fixed steel plate 45 is locked with the anchoring bolts 46 on the inner side of the old building, then the corridor prefabricated slab 22 is hoisted and placed on the elevator shaft angle steel support (not shown in the figure) at one end and directly placed on the temporary steel corbel at the other end, the above-mentioned corridor 2 and the steel column 3 are welded and fixed on site, finally the connecting assembly 43 is installed and the bolt 46 is tightened, and then the temporary steel corbel is removed, so that the number of floors required by the old building is built according to the number of floors required by the old building and the modular elevator shaft monomer 1 to complete the installation of the added elevator.
