Description

Technical Field

[0001] This utility model belongs to the field of elevator shaft technology, specifically a prefabricated weight-reducing elevator shaft. Background Technology

[0002] With the increasing aging population, some older residential communities face difficulties in daily travel due to the lack of elevators. To address this issue, the government strongly advocates for urban renewal and elevator installation. However, traditional cast-in-place reinforced concrete elevator shafts require scaffolding to be erected layer by layer, with repeated disassembly and support, resulting in long construction periods and significant dust and noise pollution. While steel-structured glass curtain wall elevators offer shorter construction periods and lower noise levels, the steel structure is prone to corrosion, has poor fire resistance, and incurs high maintenance costs. Furthermore, the vibration load generated by the elevator operation on the steel structure generates significant noise. Therefore, to address these issues, a prefabricated weight-reducing elevator shaft design is needed. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated weight-reducing elevator shaft, comprising multiple shaft bodies stacked and connected vertically, each shaft body including four assembly columns and four assembly beams. The four assembly columns are arranged in parallel rectangular shapes. The four assembly columns of two adjacent shaft bodies are connected by four assembly beams. The assembly beams are located between the adjacent two assembly columns on their closest sides. Each assembly column has a slot at its top and a plug at its bottom. Adjacent assembly columns of two adjacent shaft bodies are connected by plugs inserted into the slots.

[0004] Each of the two adjacent assembly columns has a right-angled trapezoidal support block on the upper part of the side closest to each other. One side of the right-angled trapezoidal support block has an extension block. The top of the extension block has a right-angled trapezoidal metal insert. Both ends of the bottom of the assembly beam have right-angled triangular groove metal blocks. The assembly beam is installed between the top of the right-angled trapezoidal support block and the extension block, and the right-angled trapezoidal metal insert is inserted into the inside of the right-angled triangular groove metal block. The inclined surfaces of the right-angled trapezoidal metal insert and the right-angled triangular groove metal block are in contact.

[0005] Preferably, grooves are provided inside the slot and on the surface of the insert. Before the insert is inserted into the slot, mortar is poured into the slot. After the insert is inserted into the slot with mortar, the solidified mortar makes the connection between the insert and the slot more secure.

[0006] Preferably, the right-angled trapezoidal support block and extension block are integrally cast with the assembly column, and the right-angled trapezoidal metal insert and right-angled triangular groove metal block are welded to the steel bars inside the assembly column and assembly beam respectively and integrally cast, thereby ensuring the stability and firmness of the assembly connection.

[0007] Preferably, the top of each right-angled trapezoidal support block is reserved with a square groove, and the lower part of each pair of adjacent assembly columns is provided with a pair of side metal plates. A metal clip is welded between the lower parts of each pair of side metal plates. The right-angled trapezoidal support block is located between a pair of side metal plates. The metal clip is embedded in the square groove and located below the assembly beam. The side metal plates are welded to the steel bars inside the assembly column and integrally formed by casting, thereby ensuring that the two adjacent assembly columns of the two shaft bodies can be stably and firmly assembled and spliced.

[0008] Preferably, each of the extension blocks has a grooved metal block at its bottom. The grooved metal block is welded to the steel bars inside the extension block and integrally formed by casting. Both ends of the assembly beam are movably fitted with metal rectangular collars. The lower middle part of the metal rectangular collar is threaded with a threaded pin. The top of the threaded pin inside the metal rectangular collar is rotatably connected to a metal limiting block. The metal limiting block is locked inside the grooved metal block. The bottom of the threaded pin outside the metal rectangular collar is fixedly installed with a rotating nut, thereby effectively reinforcing the connection between the assembly beam and the right-angled trapezoidal support block and the extension block.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting up assembly columns, assembly beams, slots, inserts, right-angled trapezoidal support blocks, extension blocks, right-angled trapezoidal metal inserts, right-angled triangular grooved metal blocks, square grooves, side metal plates, metal clips, grooved metal blocks, metal rectangular collars, threaded pins, metal limit blocks, and rotating nuts, this prefabricated weight-reducing elevator shaft allows for on-site assembly and splicing of the elevator shaft structure through pre-disassembly and precast casting. This effectively avoids the problems caused by on-site casting of elevator shafts and steel structure elevator shafts, thereby improving the convenience of adding elevators to old residential areas. At the same time, the prefabricated weight-reducing elevator shaft has a simple structural design, convenient and easy assembly and fixing operations, and stable and reliable assembly connections. Its performance can meet the needs of adding elevators to old residential areas. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0018] Depend on Figures 1 to 4 The present invention comprises multiple shaft bodies connected in a stacked manner. Each shaft body includes four assembly columns 1 and four assembly beams 2. The four assembly columns 1 are arranged in a parallel rectangular shape. The four assembly columns 1 of two adjacent shaft bodies are connected by four assembly beams 2. The assembly beams 2 are located between the adjacent two assembly columns 1 on their closest sides. Each assembly column 1 has a slot 3 at its top and an insert 4 at its bottom. Adjacent assembly columns 1 of two adjacent shaft bodies are connected by inserting the insert 4 into the slot 3. The slot 3 and the surface of the insert 4 are both provided with grooves. Before the insert 4 is inserted into the slot 3, mortar is poured into the slot 3. After the insert 4 is inserted into the slot 3 with mortar, the solidified mortar makes the connection between the insert 4 and the slot 3 more secure.

[0019] Each of the two adjacent assembly columns 1 has a right-angled trapezoidal support block 5 on the upper part of one side close to the other. An extension block 6 is provided on one side of the right-angled trapezoidal support block 5. A right-angled trapezoidal metal insert 7 is provided on the top of the extension block 6. Both ends of the bottom of the assembly beam 2 have right-angled triangular groove metal blocks 8. The assembly beam 2 is installed between the top of the right-angled trapezoidal support block 5 and the extension block 6, and the right-angled trapezoidal metal insert 7 is inserted into the inside of the right-angled triangular groove metal block 8. The inclined surfaces of the right-angled trapezoidal metal insert 7 and the right-angled triangular groove metal block 8 are in contact. Through the connection between the right-angled trapezoidal metal insert 7 and the right-angled triangular groove metal block 8, the inclined surface of the right-angled triangular groove metal block 8 is pressed against the inclined surface of the right-angled trapezoidal metal insert 7, so that the two adjacent assembly columns 1 can be stably and firmly connected to the assembly beam 2.

[0020] The right-angled trapezoidal support block 5 and extension block 6 are integrally cast with the assembly column 1. The right-angled trapezoidal metal insert block 7 and right-angled triangular groove metal block 8 are welded to the steel bars inside the assembly column 1 and the assembly beam 2 respectively and integrally cast, thereby ensuring the stability and firmness of the assembly connection. The top of the right-angled trapezoidal support block 5 is reserved with a square groove 9. The lower part of each pair of adjacent assembly columns 1 is provided with a pair of side metal plates 10. A metal clip 11 is welded between the lower parts of each pair of side metal plates 10. The right-angled trapezoidal support block 5 is located between a pair of side metal plates 10. The metal clip 11 is embedded in the square groove 9 and located below the assembly beam 2. The side metal plates 10 are welded to the steel bars inside the assembly column 1 and integrally cast, thereby ensuring that the two adjacent assembly columns 1 of the two shaft bodies can be stably and firmly assembled and connected.

[0021] When two adjacent assembly columns 1 of two well bodies are vertically assembled and spliced, the metal clip 11 is embedded in the inside of the square groove 9, and the right-angled trapezoidal support block 5 is located between a pair of side metal plates 10. Then, the assembly beam 2 is used to splice and connect the metal clip 11, thereby ensuring the stability and firmness of the connection.

[0022] The bottom of each extension block 6 is provided with a grooved metal block 12. The grooved metal block 12 is welded to the steel bars inside the extension block 6 and integrally formed by casting. Both ends of the assembly beam 2 are movably fitted with metal rectangular collars 13. The lower middle part of the metal rectangular collar 13 is threaded with a threaded pin 14. The top of the threaded pin 14 inside the metal rectangular collar 13 is rotatably connected with a metal limiting block 15. The metal limiting block 15 is snapped into the inside of the grooved metal block 12. The bottom of the threaded pin 14 outside the metal rectangular collar 13 is fixedly installed with a rotating nut 16, which can effectively reinforce the connection between the assembly beam 2 and the right-angled trapezoidal support block 5 and the extension block 6.

[0023] When installing the assembly beam 2, metal rectangular collars 13 are now fitted onto both ends of the assembly beam 2. After the assembly beam 2 is installed, the metal rectangular collars 13 are moved so that they are positioned between the assembly beam 2 and the extension block 6, and the metal limiting block 15 is aligned with the grooved metal block 12. Then, the rotating nut 16 is rotated using a tool. The rotation of the rotating nut 16 causes the metal limiting block 15 to engage with the inside of the grooved metal block 12 through the threaded pin 14, thereby firmly assembling the assembly beam 2 between the top of the right-angled trapezoidal support block 5 and the extension block 6.

[0024] This prefabricated weight-reducing elevator shaft allows for on-site assembly and splicing of the elevator shaft structure through pre-disassembly and precast casting. This effectively avoids the problems associated with on-site casting of elevator shafts and steel structure elevator shafts, thereby improving the convenience of adding elevators to old residential communities. At the same time, this prefabricated weight-reducing elevator shaft has a simple structural design, and the assembly, connection, and fixing operations are convenient and easy. The assembly connection is stable and reliable, and its performance can meet the needs of adding elevators to old residential communities.

[0025] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
