The terms "connected" or "coupled" and the like are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms "upper", "lower", "left", "right" and the like are only used to indicate relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0051] First, the prefabricated elevator components according to the first aspect embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

[0052] As Figure 1-7 shown, the prefabricated elevator components according to the first aspect embodiment of the present invention include a plurality of precast raft plates 110, precast shaft walls 200, precast corridor columns 300, and precast roof plates 400.

[0053] The plurality of precast raft plates 110 are used to form a foundation raft 100 by post-cast connection. The bottom of the foundation raft 100 is used to be post-cast connected to the original main foundation 001. That is to say, by industrially manufacturing a plurality of precast raft plates 110 in the factory and then post-casting to connect the precast raft plates 110 to form the foundation raft 100 on-site, compared with directly casting the foundation raft 100 on-site, the amount of wet work on-site is reduced. And considering the large size of the foundation raft 100, compared with the integral foundation raft 100, the entry and operation of large vehicles and large equipment can be avoided. Specifically, taking Figure 1 the shown foundation raft 100 as an example, the foundation raft 100 can be provided with three precast raft plates 110, for example, and a T-shaped post-cast strip is formed by post-casting. Through this T-shaped post-cast strip, the three precast raft plates 110 can be connected to form the foundation raft 100, and then the foundation raft 100 formed by post-casting is connected to the original main foundation 001, improving the reliability of the prefabricated elevator.

[0054] The bottom of the precast shaft wall 200 is used to be post-cast connected to the foundation raft 100. That is to say, after the precast shaft wall 200 is manufactured in the factory, it is connected to the foundation raft 100 by post-casting, further reducing the amount of wet work on-site and improving the on-site construction efficiency.

[0055] The bottom of the precast corridor column 300 is used for post-casting connection to the foundation raft 100. That is to say, after the precast corridor column 300 is manufactured in the factory, it is connected to the foundation raft 100 through post-casting, further reducing the amount of wet work on site and improving the on-site construction efficiency.

[0056] The precast top plate 400 is used for post-casting connection to the top of the precast corridor column 300. That is to say, after the precast top plate 400 is manufactured in the factory, it is connected to the foundation raft 100 through post-casting, further reducing the amount of wet work on site and improving the efficiency of on-site construction.

[0057] In the embodiment of the present invention, the foundation raft 100, the precast shaft wall 200, the precast corridor column 300, and the precast top plate 400 are post-cast in sequence from bottom to top on the original main body foundation 001 to form an assembled elevator structure. Since the precast components forming the assembled elevator structure are all manufactured in the factory, industrial manufacturing processes can be used to produce elevator components, and conditions such as temperature and humidity can be controlled during the production process to ensure the construction quality of the precast components. Subsequently, only the installation and connection operations of each precast component need to be carried out at the construction site, greatly shortening the construction period. Compared with cast-in-place construction, the amount of wet work on site is reduced, and the on-site construction efficiency is improved.

[0058] Furthermore, the first anchoring steel bars 114 (not shown in the figure) are provided on the precast raft 110. The first anchoring steel bars 114 are used for post-casting connection of any two adjacent precast rafts 110. That is to say, by providing the first anchoring steel bars 114 on each precast raft 110 and connecting two adjacent precast rafts 110 through the first anchoring steel bars 114, usually preferably by welding connection, and then through post-casting, any two adjacent precast rafts 110 are connected to form the foundation raft 100. Specifically, taking Figure 1 the shown foundation raft 100 as an example, during on-site construction, for example, the first anchoring steel bars 114 can be provided on the bottom surface of the first precast raft 110 (corresponding to Figure 1 above the T-shaped post-cast strip), for example, the first anchoring steel bars 114 can also be provided on the top surface and the right side surface of the second precast raft 110 (corresponding to Figure 1 below the left side of the T-shaped post-cast strip), for example, the first anchoring steel bars 114 can also be provided on the top surface and the left side surface of the third precast raft 110 (corresponding to Figure 1 below the right side of the T-shaped post-cast strip), and then through post-casting, the top surface of the second precast raft 110 is connected to the bottom surface of the first precast raft 110; the right side surface of the second precast raft 110 is connected to the left side surface of the third precast raft 110; the top surface of the third precast raft 110 is connected to the bottom surface of the first precast raft 110, that is, it forms Figure 1The shown foundation raft 100. It should be noted that the quantity and combination mode of the precast raft 110 in the embodiment of the present invention include but are not limited to Figure 1 the shown structure.

[0059] Furthermore, a first protruding steel bar 111 is arranged on the upper surface of the foundation raft 100, and the bottom of the precast shaft wall 200 has a first grouting sleeve 211 matching with the first protruding steel bar 111. The first protruding steel bar 111 and the first grouting sleeve 211 are used for grouting connection between the foundation raft 100 and the precast shaft wall 200. That is to say, the foundation raft 100 and the precast shaft wall 200 are connected through the first grouting sleeve 211 to Figure 1 Taking the shown foundation raft 100 as an example, for instance, the precast shaft wall 200 can be connected by post-casting to the upper surface of the third precast raft 110 (corresponding to Figure 1 the lower right side of the T-shaped post-cast strip in). Specifically, as Figure 3 shown, a part of the first protruding steel bar 111 is arranged inside the foundation raft 100, and the other part protrudes from the upper surface of the foundation raft 100. The first grouting sleeve 211 is embedded at the bottom of the precast shaft wall 200. During on-site construction, first, the first grouting sleeves 211 inside the precast shaft wall 200 are connected to the first protruding steel bars 111 on the foundation raft 100 one by one, and then grouting material is injected. The first protruding steel bar 111 and the first grouting sleeve 211 are connected through the bonding and biting action between the grouting materials to realize the connection between the precast shaft wall 200 and the foundation raft 100.

[0060] Furthermore, a first protruding steel bar 112 is also arranged on the upper surface of the foundation raft 100, and the bottom of the precast corridor column 300 has a second grouting sleeve 311 matching with the first protruding steel bar 112. The first protruding steel bar 112 and the second grouting sleeve 311 are used for grouting connection between the foundation raft 100 and the precast corridor column 300. That is to say, the foundation raft 100 and the precast corridor column 300 are connected through the second grouting sleeve 311 to Figure 1 Taking the shown foundation raft 100 as an example, for instance, the precast corridor column 300 can be connected by post-casting to the upper surface of the second precast raft 110 (corresponding to Figure 1 the lower left side of the T-shaped post-cast strip in). Specifically, as Figure 4As shown, a part of the first protruding steel bar 112 is arranged in the foundation raft 100, and the other part protrudes from the upper surface of the foundation raft 100, and the second grouting sleeve 311 is buried in the bottom of the prefabricated corridor column 300. During on-site construction, in order to reduce the workload of on-site construction, the second grouting sleeve 311 on the prefabricated corridor column 300 and the first protruding steel bar 112 on the foundation raft 100 need to be pre-assembled in the factory. During on-site construction, the second grouting sleeve 311 in the prefabricated corridor column 300 is connected to the first protruding steel bar 112 on the foundation raft 100 in a one-to-one correspondence, and then the grouting material is injected, and the first protruding steel bar 112 and the second grouting sleeve 311 are connected through the bonding and biting action between the grouting materials, so as to realize the connection between the prefabricated corridor column 300 and the foundation raft 100.

[0061] Further, the prefabricated top plate 400 includes a first top plate 410 (corresponding to Figure 5 The right side portion) and the second top plate 420 (corresponding to Figure 5 The second top plate 420 is connected to the first top plate 410, a first through hole 421 is formed on the second top plate 420, and a steel column 312 is provided on the top of the prefabricated corridor column 300, the steel column 312 is provided in the first through hole 421, and the steel column 312 is used for post-casting connection between the prefabricated corridor column 300 and the second top plate 420. That is to say, during on-site construction, the second top plate 420 is first connected to the prefabricated corridor column 300, and then the first top plate 410 is connected to the second top plate 420, so that the prefabricated top plate 400 is connected to the prefabricated corridor column 300.

[0062] Furthermore, the prefabricated top plate 400 further includes a connecting member 430, one side of the first top plate 410 (corresponding to Figure 5 The left side of the second top plate 420 is formed with two connecting arms 411 extending toward the second top plate 420. One side of the second top plate 420 (corresponding to Figure 5 The first top plate 410 is formed with two side wings 422 extending toward the first top plate 410 (on the right side in the figure), and the connector 430 is used for post-casting connection of the connecting arm 411 and the side wings 422. That is, the first top plate 410 is connected to the second top plate 420 by post-casting connection of the connecting arm 411 and the side wings 422 through the connector 430. During construction, the second top plate 420 can be first connected to the precast corridor column 300 cast on the foundation raft 100, and then the second top plate 420 and the first top plate 410 are connected by the connector 430. Compared with the integral precast top plate 400, the post-casting connection of the first top plate 410 and the second top plate 420 realizes the precise installation of the precast top plate 400, ensures the parallelism and verticality of the precast top plate 400, and improves the convenience of post-casting construction.

[0063] Further, a second anchoring steel bar (not shown in the figure) is provided at one end of the connecting arm 411 facing the second top plate 420, and a third anchoring steel bar (not shown in the figure) is provided at one end of the flank 422 facing the first top plate 410. The connecting member 430 has a main reinforcement bar 434, and the main reinforcement bar 434 extends out of the connecting member 430 and is connected to the second anchoring steel bar or the third anchoring steel bar. That is to say, the third anchoring steel bar on the flank 422 of the second top plate 420 is connected to the main reinforcement bar 434 of the connecting member 430, and the second anchoring steel bar on the connecting arm 411 of the first top plate 410 is also connected to the main reinforcement bar 434 of the connecting member 430. The first top plate 410 is connected to the second top plate 420 through the connecting arm 411, the second anchoring steel bar, the main reinforcement bar 434, the third anchoring steel bar, and the flank 422 in sequence.

[0064] Further, the connecting arm 411 is connected to the flank 422 through two connecting members 430. As Figure 6 shown, the connecting member 430 further has an end plate 431, longitudinal reinforcement bars 433, and a steel plate 432. The end plate 431 is located on the side away from the extending end of the main reinforcement bar 434. The first end of the longitudinal reinforcement bar 433 is connected to the end of the end plate 431, and the second end is connected to the other end of the main reinforcement bar 434. The steel plate 432 is connected to the end plate 431, and the two connecting members 430 are connected through the end plate 431. That is to say, the first top plate 410 is connected to the second top plate 420 through the connecting arm 411, the second anchoring steel bar, the main reinforcement bar 434 of one of the connecting members, the end plate 431 of one of the connecting members, the end plate 431 of the other connecting member, the main reinforcement bar 434 of the other connecting member, the third anchoring steel bar, and the flank 422 in sequence. During on-site construction, first, the extending end of the main reinforcement bar 434 of one of the connecting members (corresponding to Figure 6 the left end of the left connecting member) is connected to the third anchoring steel bar (not shown in the figure) on the flank 422. This connection method is preferably a welded connection. Then, the extending end of the main reinforcement bar 434 of the other connecting member 430 (corresponding to Figure 6 the right connecting member) (corresponding to Figure 6 the right end of the right connecting member) is connected to the second anchoring steel bar (not shown in the figure) on the connecting arm 411. This connection method is preferably a welded connection. Then, the end plate 431 of one of the connecting members (corresponding to Figure 6 the left connecting member) (corresponding to Figure 6 the right end of the left connecting member) is connected to the end plate 431 of the other connecting member (corresponding to Figure 6 the right connecting member) (corresponding to Figure 6The left end of the right connecting member (), this connection method is preferably a welded connection. During this welded connection process, the relative positions of the two connecting members 430 can be adjusted by stagger-welding the two end plates 431, achieving the precise installation of the first top plate 410, ensuring the parallelism and perpendicularity of the first top plate 410, improving the convenience of post-pouring construction. Finally, pour the connecting member 430, and connect one of the connecting members 430 to the flank 422, and the other connecting member 430 to the connecting arm 411. In addition, by arranging the end plate 431, steel plate 432, longitudinal reinforcement 433 and main reinforcement 434 in the connecting member 430, the mechanical strength of the connecting member 430 is improved.
