[0002] Adding elevators to old communities is an important livelihood project, which can effectively promote the participation of the elderly and disabled in social life. At present, the structural system of adding elevators to old communities mainly adopts steel structure, and a small part is cast-in-place reinforced concrete structure. Steel structure has the advantages of light weight, fast construction and low cost, but the rigidity is relatively small, the corrosion resistance requirement is high, and the later maintenance cost is large; while the cast-in-place reinforced concrete structure has larger rigidity than the steel structure, higher use comfort and lower later maintenance cost, but has long construction period, large construction pollution, large occupation and large disturbance. Therefore, combining the advantages of reinforced concrete structure and steel structure, seeking a structure system that can meet the requirements of cost, safety and speed at the same time is an urgent problem to be solved in the development process of adding elevators to old communities.

[0003] In order to save energy and reduce emissions, the state and local governments are vigorously promoting the prefabricated building. However, due to technical and cost reasons, there are not many buildings using whole prefabricated structure, and even fewer using prefabricated structure in elevator adding projects. The commonly used prefabricated structure component is a composite beam slab, and the main feature of the elevator adding structure is to require frame beams and frame columns to bear the load. The whole prefabricated structure is to combine the advantages of steel structure, and is segmented and manufactured in the factory, and only a few hours of work are needed to complete the whole hoisting after reaching the site, which greatly shortens the construction period, reduces the influence on the life of the owner, and makes the elevator adding project "minimize the influence on people's life and maximize the benefits".

[0040] The application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It is noted that the aspects described below in conjunction with the accompanying drawings and specific embodiments are only exemplary and should not be understood as limiting the scope of protection of the application in any way.

[0041] Embodiment 1:

[0042] Please refer to Figures 1-6 The embodiment describes a prefabricated elevator installation structure, which comprises a prefabricated base 1, a plurality of prefabricated standard sections 2 and a prefabricated top layer 3. The number of prefabricated standard sections 2 corresponds to the number of floors of the existing building where the elevator is to be installed, and each prefabricated standard section 2 corresponds to each floor.

[0043] Further, according to the different existing buildings, the prefabricated standard section 2 is divided into two types:

[0044] I. The existing building itself has a corridor structure connected with the elevator, and the prefabricated standard section 2 is a prefabricated elevator shaft 21;

[0045] II. The existing building itself has no corridor structure, and the prefabricated standard section 2 comprises a prefabricated elevator shaft 21 and a prefabricated corridor 22 integrally cast and formed. This embodiment is described in detail in this structure.

[0046] Further, the prefabricated base 1 is provided at the place where the elevator is to be installed; a plurality of prefabricated standard sections 2 are stacked on the prefabricated base 1, the prefabricated standard section 2 is provided with a connecting through hole 25, the first connecting piece 23 is arranged in the connecting through hole 25, the first connecting pieces 23 between adjacent prefabricated standard sections 2 are connected in the connecting through hole 25, and the connecting through holes 25 between adjacent prefabricated standard sections 2 are connected by grouting; the prefabricated top layer 3 is arranged on the uppermost layer of the plurality of prefabricated standard sections 2.

[0047] When the prefabricated standard section 2 comprises a prefabricated elevator shaft 21 and a prefabricated corridor 22 integrally cast and formed, there are three ways to set the connecting through hole 25:

[0048] I. The connecting through hole 25 is arranged in the prefabricated elevator shaft 21;

[0049] II. The connecting through hole 25 is arranged in the prefabricated corridor 22;

[0050] III. The connecting through hole 25 is arranged in the prefabricated elevator shaft 21 and the prefabricated corridor 22, that is, the prefabricated elevator shaft 21 of each floor is connected, and the prefabricated corridor 22 of each floor is also connected.

[0051] In this embodiment, in order to simplify the operation and installation, the first method can be used.

[0052] Specifically, the connecting through hole 25 is vertically arranged in the prefabricated elevator shaft 21, and the prefabricated elevator shaft 21 is also provided with a reserved operation hole 24 to facilitate the connection between the first connecting piece 23 of adjacent prefabricated elevator shafts 21. Therefore, the reserved operation hole 24 is connected to the connecting through hole 25, and the connecting point of the first connecting piece 23 of the adjacent prefabricated standard section 2 is located at the reserved operation hole 24.

[0053] The first connecting piece 23 is a connecting member for connecting adjacent prefabricated standard sections 2, which is arranged in the connecting through hole 25. Therefore, the positions of the connecting through holes 25 of adjacent prefabricated standard sections 2, and even all the connecting through holes 25 of the prefabricated standard sections 2, are opposite.

[0054] In order to realize the quick connection of the first connecting piece 23, the first connecting piece 23 is a connecting rod, and the two ends of the connecting rod are provided with threads, that is, the connecting rods of adjacent prefabricated standard sections 2 are connected through a double-port threaded sleeve 25. Preferably, the connecting rod is a threaded rod or a reinforcing bar with threads at both ends, and the double-port threaded sleeve 25 has openings at both ends and is internally provided with internal threads matched with the threads at the ends of the connecting rod.

[0055] It should be noted that the connection method of the double-port threaded sleeve 25 is only one connection method of the first connecting piece 23, and other connection methods such as welding connection, binding connection, bolt connection, and grouting anchor connection can also be used as the implementation means of this embodiment.

[0056] Specific installation method: the connecting node of the connecting rod in the adjacent prefabricated standard section 2 is defined at the reserved operation hole 24, because the reserved operation hole 24 is connected to the connecting through hole 25, so the connection operation can be performed at the reserved operation hole 24, and after the connection of the connecting rod is completed, there is no connecting structure between the connecting rod and the prefabricated standard section 2 for connection, so subsequent grouting connection of the connecting through hole 25 is needed to form a whole with the connecting rod and the prefabricated standard section 2. At this time, the connecting through hole 25 of the topmost prefabricated standard section 2 can also be used as a grouting hole for grouting.

[0057] The above has described the connection method between the prefabricated standard sections 2, and the connection method between the prefabricated base 1 and the prefabricated standard section 2 can also be completed by means of the connecting through hole 25.

Preferably, please refer to Figure 2The second connecting member 11 is a connecting steel bar or a connecting screw rod, one end of which is embedded in the prefabricated base 1 vertically during prefabrication, and the other end is threaded and inserted into the connecting through hole 25 of the prefabricated standard section 2, and is connected to the first connecting member 23 through the double-port threaded sleeve 25.

[0058] Similarly, please refer to Figure 3 , the prefabricated top layer 3 is provided with a third connecting member 31 connected to the first connecting member 23 in the prefabricated standard section 2 close to the prefabricated top layer 3. Preferably, the third connecting member 31 is a connecting steel bar or a connecting screw rod, one end of which is embedded in the prefabricated top layer 3 vertically during prefabrication, and the other end is threaded and inserted into the connecting through hole 25 of the prefabricated standard section 2, and is connected to the first connecting member 23 through the double-port threaded sleeve 25.

[0059] Further, the connecting through holes 25 at each corresponding position of adjacent prefabricated standard sections 2 are defined as a group, at least three groups are provided in this embodiment, which are provided at the locations described in Figure 5 and Figure 6 , one group is provided at the external corner of the prefabricated elevator shaft 21, and one group is provided on each side of the side surface.

The second connecting member 11 is provided in advance during production, and the number thereof corresponds to the number of connecting through holes 25 in each prefabricated standard section 2.

[0065] Similarly, the prefabricated top layer 3 is provided with a third connecting member 31, which is connected to the first connecting member 23 in the prefabricated standard section 2 close to the prefabricated top layer 3.
