Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of elevator shaft waterproofing, and more specifically, to a waterproof structure for the wall of an elevator shaft. Background Art
[0002] The design and construction of the elevator shaft wall are one of the key factors to ensure the safe and stable operation of the elevator system. The elevator shaft wall not only has to bear the role of structural support, but also has to have good waterproof, sound insulation, fire prevention and other functions. The wall needs to have sufficient strength to withstand the dynamic load generated by the elevator operation and its own weight, and it is an important construction project to ensure the safe operation of the elevator.
[0003] The existing elevator shaft walls are usually made of bricks and concrete, which have good load-bearing capacity and durability. A waterproof mortar is applied to its surface to prevent water from penetrating into the wall and protect the wall from water damage. When necessary, a waterproof coating is also applied to improve the waterproof performance.
[0004] In the actual use of the existing technology, since it is difficult to drain water once it enters the elevator shaft, relying solely on a single layer of waterproof mortar or waterproof coating is difficult to resist the penetration of water vapor into the wall, and the waterproof effect is poor. Therefore, a waterproof structure for the elevator shaft wall is proposed. Summary of the Utility Model

It comprehensively coats the inside of the elevator shaft with a waterproof coating to prevent water from penetrating the wall, and also coats the side seams of the elevator door openings. The waterproof coating is a polymer cement waterproof coating, which is based on cement and mixed with materials such as polymer emulsion, and has good elasticity, weather resistance and adhesion, and is suitable for humid environments such as basements and bathrooms. Then, waterproof coiled materials one are pasted at the four corners of the elevator shaft, and waterproof coiled materials two are pasted inside the water collecting trough and on the convex blocks, and used in combination with the first layer of waterproof coating to further enhance the waterproof effect, and perform secondary waterproofing on the corners and bottom water collecting areas of the elevator shaft that are prone to water leakage, so as to improve the waterproof effect.

[0028] Embodiment 1
[0029] Referring to Figure 1-2 , which is the first embodiment of the present utility model. This embodiment provides a waterproof structure for the wall of an elevator shaft, including an elevator shaft 1. A waterproof coating 4 is evenly applied to the inner cavity of the elevator shaft 1. A first waterproof roll 5 is laid at the corners of the elevator shaft 1, and a second waterproof roll 6 is laid on the inner wall of the water collecting trough 3 and the convex block 2.
[0030] Specifically, an elevator door opening 101 is provided on one side of the elevator shaft 1. The inner cavity of the elevator door opening 101 is evenly coated with the waterproof coating 4. The outer surface of the convex block 2 is evenly coated with the waterproof coating 4. The first waterproof roll 5 and the second waterproof roll 6 cover the outer surface of the waterproof coating 4. When the first waterproof roll 5 and the second waterproof roll 6 are laid, the overlapping width at the joint is 80 mm to 100 mm. The first waterproof roll 5 and the second waterproof roll 6 are self-adhesive waterproof rolls.
[0031] Furthermore, the waterproof coating 4 is fully applied inside the elevator shaft 1 to prevent water from penetrating the wall, and the side seams of the elevator door opening 101 are also coated. The waterproof coating 4 is a polymer cement waterproof coating, which is based on cement and mixed with polymer emulsion and other materials, and has good elasticity, weather resistance and adhesion, and is suitable for damp environments such as basements and bathrooms.
[0032] Then, the first waterproof roll 5 is pasted at the four corners of the elevator shaft 1, and the second waterproof roll 6 is pasted inside the water collecting trough 3 and on the convex block 2, and used in combination with the first layer of waterproof coating 4 to further enhance the waterproof effect, and perform secondary waterproofing on the corners and the bottom water collecting area of the elevator shaft 1 where water leakage is likely to occur, so as to improve the waterproof effect.

Remove the release film on the back of the roll to expose the bonding surface, lay the roll smoothly on the base layer according to the layout position, and repeatedly roll along the direction of the roll with a roller or a heavy object to ensure that the roll is tightly bonded to the base layer. The self-adhesive operation is simpler and more suitable for use in a narrow space such as the elevator shaft 1.

Based on the previous embodiment, a convex block 2 is fixedly connected to the bottom of the inner cavity of the elevator shaft 1. The elevator shaft 1 and the convex block 2 cooperate to form a rectangular collecting groove 3 in a shape of a Chinese character "hui". A water suction pipe 7 is laid in the inner cavity of the collecting groove 3. The water suction pipe 7 is communicated with a main pipe 8, and a plurality of water suction ports 10 are uniformly communicated with the outer surface of the water suction pipe 7.
[0036] Specifically, one end of the main pipe 8 away from the water suction pipe 7 penetrates through the elevator shaft 1 and is provided with a water pump 9. One end of the water suction port 10 is threadedly connected with a pipe cap 11, and a plurality of water inlet holes 12 are uniformly opened on the pipe cap 11.

[0037] Furthermore, the operator fixedly installs a convex block 2 at the bottom of the elevator shaft 1. The convex block 2 cooperates with the bottom of the elevator shaft 1 to form a rectangular collecting groove 3 in a shape of a Chinese character "hui" for collecting the water seeping into the shaft. When the water source leaking into the collecting groove 3 accumulates, the water pump 9 can be started at this time to pump the accumulated water in the collecting groove 3 to the main pipe 8 through the water suction pipe 7, and finally discharged from the elevator shaft 1. A plurality of water suction ports 10 are arranged on the water suction pipe 7, which can improve the water pumping efficiency and ensure that the accumulated water in each area of the collecting groove 3 can be effectively pumped. The water suction port 10 is provided with a pipe cap 11 and a water inlet hole 12 to prevent sundries from entering. At the same time, it can also be directly rotated and unscrewed for easy maintenance, preventing the metal components in the elevator shaft 1 such as guide rails and screws from being corroded due to accumulated water and affecting their normal use.
[0038] Working principle: During the use of the device, the operator fixedly installs a convex block 2 at the bottom of the elevator shaft 1. The convex block 2 cooperates with the bottom of the elevator shaft 1 to form a rectangular collecting groove 3 in a shape of a Chinese character "hui" for collecting the water seeping into the shaft. Then, a waterproof coating 4 is fully applied to the inside of the elevator shaft 1 to prevent water from penetrating the wall, and the side seams of the elevator door opening 101 are also coated. Then, waterproof coiled materials one 5 are pasted at the four corners of the elevator shaft 1, and waterproof coiled materials two 6 are pasted inside the collecting groove 3 and on the convex block 2, which are used in superposition with the first-layer waterproof coating 4 to further enhance the waterproof effect. When the water source leaking into the collecting groove 3 accumulates, the water pump 9 can be started at this time to pump the accumulated water in the collecting groove 3 to the main pipe 8 through the water suction pipe 7, and finally discharged from the elevator shaft 1. A plurality of water suction ports 10 are arranged on the water suction pipe 7, which can improve the water pumping efficiency and ensure that the accumulated water in each area of the collecting groove 3 can be effectively pumped.
