Technical Field

[0001] This utility model relates to the field of elevator shafts, and in particular to a prefabricated elevator shaft constructed using existing square steel pipes. Background Technology

[0002] With social development, old residential communities, as an important part of urban living, have received much attention for improving their living environment. Among them, adding elevators to old residential communities is an important measure to improve the convenience of residents' lives. It can effectively solve the problem of difficulty for the elderly and people with mobility impairments to go up and down stairs, improve the living quality and livability of old residential communities, and at the same time increase the property value of old residential communities.

[0003] Adding an elevator inevitably requires the construction of an elevator shaft. The elevator shaft is a crucial support structure for elevator operation, bearing the weight of the elevator car, counterweight, and other components, and ensuring the stability and safety of elevator operation. However, in existing elevator shaft installations, the columns and beams are only connected by bolts. This connection method is not reliable enough. Over long-term use, due to vibrations generated by elevator operation, building settlement, and the influence of the external environment, the bolts are prone to loosening, which leads to a decrease in the stability of the connection between the columns and beams. This may cause deformation of the elevator shaft structure and even pose safety hazards, affecting the normal operation and safety of the elevator. Summary of the Invention

[0004] In view of this, the present invention provides a prefabricated elevator shaft constructed using existing square steel pipes. The main technical problem to be solved is that the columns and beams in the existing elevator shaft frame are only connected by bolts, which is not reliable, is easy to loosen, and poses a safety hazard.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a prefabricated elevator shaft constructed using existing square steel pipes, comprising a base, a shaft frame one, and multiple shaft frames two. The shaft frame one is fixedly installed on the top of the base, and the multiple shaft frames two are sequentially fixedly installed on the top of the shaft frame one. The base, shaft frame one, and shaft frames two are all equipped with multiple columns and beams inside. The base, shaft frame one, and shaft frames two are all equipped with four rectangularly distributed columns inside. The columns are hollow square tubes. Multiple beams are connected between two adjacent columns through T-shaped plates. The inner walls of the upper and lower columns are fixedly connected by connectors and L-shaped plates.

[0006] The T-shaped plate includes a horizontal plate and a vertical plate. The vertical plate is welded and fixed perpendicularly to the horizontal plate. The outer wall of the column has multiple slots. One end of the horizontal plate is inserted into the slot and contacts and abuts against the inner wall of the column. One side of the vertical plate is attached to the outer wall of the column. Both the horizontal plate and the vertical plate are welded and fixed to the column.

[0007] A crossbeam is bolted to the inner wall of the two transverse plates on the same side at the end away from the column, and another crossbeam is bolted to the outer wall of the two longitudinal plates on the same side.

[0008] The connector includes a U-shaped plate and a plug. The U-shaped plate is placed inside the cavity of the column and fixed to the upper and lower columns by bolts. The plug is fixedly welded to the end of the U-shaped plate. The top and bottom of the upper and lower columns are provided with slots II, and the plug is inserted into the slots II of the upper and lower columns.

[0009] The L-shaped plate is located opposite the connector and is fixedly connected to the upper and lower columns by bolts.

[0010] By adopting the above technical solutions, the connection strength and stability between the columns and beams, and between the upper and lower columns, are enhanced, thereby improving the overall structural safety of the elevator shaft.

[0011] As a further description of the above technical solution: a diagonal tie rod is bolted between the upper and lower diagonally opposite T-shaped plates on the same side of the column. The diagonal tie rod is located between the upper and lower crossbeams on the same side, and the diagonal tie rod and the two adjacent upper and lower crossbeams are installed in a Z-shape.

[0012] By adopting the above technical solutions, the connection between the columns and beams is further strengthened, and the deformation resistance of the elevator shaft structure is improved.

[0013] As a further description of the above technical solution: An elevator entrance is provided on the side of the base, hoist frame one, and multiple hoist frames two corresponding to the building entrance, and the elevator entrance is constructed as follows:

[0014] Remove the crossbeams and diagonal braces at the positions corresponding to the entrance of the building, including the base, derrick one, and multiple derrick twos.

[0015] By adopting the above technical solutions, residents can easily access the elevators, ensuring that the elevators are matched with the building entrances and meeting actual usage needs.

[0016] As a further description of the above technical solution: a crossbeam is retained between the upper and lower elevator entrances, and a reinforcing crossbeam is provided at the bottom of the retained crossbeam, the reinforcing crossbeam being welded between the two adjacent columns.

[0017] By adopting the above technical solution, the structural strength of the area is ensured while opening the elevator entrance, preventing a decrease in structural stability due to the removal of some beams and tie rods.

[0018] By employing the above technical solution, the prefabricated elevator shaft constructed using existing square steel pipes of this utility model has at least the following beneficial effects:

[0019] 1. Compared with existing technologies, this prefabricated elevator shaft using existing square steel pipes, by setting T-shaped plates, inserts the horizontal plates into the slots of the columns and abuts against the inner wall of the columns and welds them in place, while the longitudinal plates are attached to the outer wall of the columns and welded in place. Then, the crossbeams are connected to the horizontal and longitudinal plates respectively by bolts, which realizes a reliable connection between the columns and the crossbeams, enhances the stability of the elevator shaft structure, and reduces safety hazards.

[0020] 2. Compared with the existing technology, this prefabricated elevator shaft using existing square steel pipes is equipped with U-shaped plates and L-shaped plates. The U-shaped plates are placed in the inner cavity of the columns and fixed to the upper and lower columns with bolts. The inserts at the ends of the U-shaped plates are inserted into the slots of the upper and lower columns. The L-shaped plates are fixed to the upper and lower columns with bolts on the opposite side of the connectors. The upper and lower columns are fixedly connected from both the inside and outside, which realizes a reliable connection between the two columns and improves the overall structural strength of the shaft.

Compared with the existing technology, this prefabricated elevator shaft, which utilizes existing square steel pipes, is equipped with diagonal tie rods that are bolted between T-shaped plates at opposite corners on the same side of the column. The tie rods are also installed in a Z-shape with the two adjacent horizontal beams, which further strengthens the connection between the column and the horizontal beams, reinforces the shaft structure, and improves the shaft's vibration and deformation resistance.

[0031] Reference Figure 1-7 This utility model provides a prefabricated elevator shaft constructed using existing square steel pipes: it includes a base 1, a shaft frame 2, and multiple shaft frames 3. The shaft frame 2 is fixedly installed on top of the base 1, providing a stable foundation support for the entire elevator shaft, allowing the shaft frame 2 to be stably installed on top of it. Multiple shaft frames 3 are sequentially fixedly installed on top of the shaft frame 2. By stacking multiple shaft frames 3 sequentially, a shaft structure of suitable height can be constructed according to the required lifting height of the elevator. The base 1, shaft frame 2, and shaft frames 3 are all equipped with multiple columns 4 and beams 6 inside. The columns 4 serve as the main vertical support components, bearing the vertical load of the shaft, while the beams 6 connect adjacent columns 4 to form an overall frame structure. The base 1, derrick 1 2, and derrick 2 3 are each equipped with four rectangular columns 4. The four columns 4 are located at the four corners of the rectangle, forming a stable rectangular frame structure. The columns 4 are hollow square tubes. The hollow structure reduces its own weight while ensuring structural strength, thus reducing the load on the foundation. Multiple crossbeams 6 are connected between two adjacent columns 4 by T-shaped plates 5. The T-shaped plates 5 act as a bridge connecting the columns 4 and the crossbeams 6, allowing the crossbeams 6 to be firmly installed between the columns 4. The inner walls of the upper and lower columns 4 are fixedly connected by connectors 8 and L-shaped plates 9. Through the combined action of connectors 8 and L-shaped plates 9, the connection strength between the upper and lower columns 4 is enhanced, ensuring the stability of the vertical structure of the shaft.

[0032] The T-shaped plate 5 includes a horizontal plate 501 and a vertical plate 502. The vertical plate 502 is perpendicularly welded to the horizontal plate 501. This welding method forms the horizontal plate 501 and the vertical plate 502 into a single unit, improving the structural strength of the T-shaped plate 5. The outer wall of the column 4 has multiple slots 401, which provide positioning and accommodating space for the installation of the horizontal plate 501. One end of the horizontal plate 501 is inserted into the slot 401 and contacts and abuts against the inner wall of the column 4. This insertion connection enables… The horizontal plate 501 restricts the horizontal displacement and abuts against the inner wall of the column 4, increasing the contact area and improving the stability of the connection. One side of the longitudinal plate 502 is close to the outer wall of the column 4, increasing the contact area between the longitudinal plate 502 and the column 4, making the connection between the two more stable. Both the horizontal plate 501 and the longitudinal plate 502 are welded and fixed to the column 4. The welding and fixing further firmly connects the T-shaped plate 5 to the column 4, preventing the T-shaped plate 5 from loosening or falling off, and providing a reliable foundation for the subsequent connection of the crossbeam 6.

[0033] Two transverse plates 501 on the same side are bolted to the inner wall of the end away from the column 4 with a crossbeam 6. The bolted connection facilitates the installation and disassembly of the crossbeam 6 and ensures the connection strength between the crossbeam 6 and the transverse plate 501. Two longitudinal plates 502 on the same side are bolted to the outer wall with another crossbeam 6. By connecting the crossbeam 6 to the outer wall of the longitudinal plate 502, adjacent columns 4 can be connected from different directions, which enhances the integrity and stability of the frame structure.

[0034] The connector 8 includes a U-shaped plate 801 and an insert block 802. The U-shaped plate 801 is placed inside the cavity of the column 4. The U-shaped structure can better fit the inner wall of the column 4, increasing the contact area. It is fixed to the upper and lower columns 4 by bolts. The bolt connection allows the U-shaped plate 801 to be tightly connected to the upper and lower columns 4 at the same time, transmitting vertical loads. The insert block 802 is fixedly welded to the end of the U-shaped plate 801. The welding fixation ensures the connection strength between the insert block 802 and the U-shaped plate 801. The top and bottom of the upper and lower columns 4 are provided with slots 402. The slots 402 provide a precise installation position for the insert block 802. The insert block 802 is inserted into the slots 402 of the upper and lower columns 4. The cooperation between the insert block 802 and the slots 402 can limit the relative displacement between the upper and lower columns 4, prevent horizontal misalignment, and enhance the stability of the connection.

[0035] The L-shaped plate 9 is located opposite the connector 8. Its L-shaped structure allows it to fit against the inner corner of the column 4, fixing the upper and lower columns 4 from different directions. It is also fixedly connected to the upper and lower columns 4 by bolts. The L-shaped plate 9 and the connector 8 fix the upper and lower columns 4 from opposite sides, forming a two-way constraint, which further improves the firmness and stability of the connection between the upper and lower columns 4.

[0036] Diagonal braces 7 are bolted between the upper and lower diagonally opposite T-shaped plates 5 on the same side of the column 4. The bolted connection facilitates the installation and adjustment of the diagonal braces 7. The diagonal braces 7 are located between the upper and lower crossbeams 6 on the same side, making reasonable use of the space between the crossbeams 6 for installation. The diagonal braces 7 and the two adjacent upper and lower crossbeams 6 are installed in a Z-shape. The Z-shaped installation method enables the diagonal braces 7 to exert tension on the upper and lower crossbeams 6 and the column 4, forming a stable triangular force-bearing structure, thereby enhancing the overall rigidity and deformation resistance of the structure in this area.

[0037] An elevator entrance is provided on the side of the base 1, hoist 1 2, and multiple hoist 2 3 corresponding to the building entrance. The elevator entrance is designed to facilitate residents' access to the elevator car from the building. The elevator entrance is constructed by removing the crossbeams 6 and diagonal braces 7 at the positions of the base 1, hoist 1 2, and multiple hoist 2 3 corresponding to the building entrance. By removing the crossbeams 6 and diagonal braces 7 at the corresponding positions, a passage for people to enter and exit is formed, matching the position of the building entrance and meeting actual usage needs.

[0038] A crossbeam 6 is retained between the upper and lower elevator entrances. The retained crossbeam 6 can maintain the connection between the columns 4 in this area, and avoid the structural strength from decreasing due to the removal of too many components. A reinforcing crossbeam 10 is installed at the bottom of the retained crossbeam 6. The reinforcing crossbeam 10 is welded between two adjacent columns 4. The welding fixation makes the reinforcing crossbeam 10 and the columns 4 form an integral whole. The reinforcing crossbeam 10 can share the load borne by the retained crossbeam 6, further strengthen the structural strength of this area, and ensure the structural stability of the elevator entrance.

[0039] Working principle: First, install the base 1, ensuring it is placed on a flat and solid foundation to provide stable support for the entire shaft structure. Then, fix the derrick 2 on top of the base 1. The four columns 4 inside the derrick 2 are arranged in a rectangular pattern. Then, insert the transverse plate 501 of the T-shaped plate 5 into the slot 401 of the column 4, so that the transverse plate 501 is pressed against the inner wall of the column 4 and the longitudinal plate 502 is pressed against the outer wall of the column 4. Then, weld the transverse plate 501 and the longitudinal plate 502 to the column 4. Finally, use bolts to connect the crossbeam 6 to the inner wall of the two transverse plates 501 and the outer wall of the two longitudinal plates 502 on the same side, forming the frame structure of the derrick 2.

[0040] Next, multiple derricks 2 3 are installed sequentially on the top of derrick 1 2. During installation, the upper and lower columns 4 are fixedly connected by connectors 8 and L-shaped plates 9. U-shaped plates 801 are placed at the top of the inner cavity of the lower column 4 and the bottom of the inner cavity of the upper column 4, so that the inserts 802 at the end of the U-shaped plates 801 are inserted into the slots 402 of the upper and lower columns 4, and the U-shaped plates 801 are fixed to the upper and lower columns 4 with bolts. At the same time, L-shaped plates 9 are installed opposite the connectors 8, and L-shaped plates 9 are fixed to the upper and lower columns 4 with bolts to achieve a firm connection between the upper and lower derricks.

[0041] Between the upper and lower diagonally opposite T-shaped plates 5 on the same side of the column 4, the diagonal tie rods 7 are bolted together so that the diagonal tie rods 7 are located between the upper and lower crossbeams 6 on the same side and form a Z-shape with the upper and lower adjacent crossbeams 6, thereby enhancing the stability of the structure.

[0042] Subsequently, based on the location of the building entrance, elevator entrances are opened on the corresponding side of the base 1, hoist 1 2 and multiple hoist 2 3. The crossbeam 6 and diagonal tie rod 7 at this location are removed. A crossbeam 6 is retained between the upper and lower elevator entrances, and a reinforcing crossbeam 10 is welded to the bottom of the retained crossbeam 6. The two ends of the reinforcing crossbeam 10 are welded and fixed to the two adjacent columns 4.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
