Moreover, it should be understood that the language and terminology employed herein are for the purpose of description and should not be regarded as limiting.

[0017] The details of the utility model will now be discussed with reference to the accompanying drawings, which illustrate the utility model by way of example only. In the drawings, similar features or components can be denoted by the same reference signs.

[0018] The use of the terms "comprising," "having," and "including," and variations thereof, herein means to include the items listed herein, their equivalents, and additional items. While reference may be made in the description of the drawings to directions such as above, below, upward, downward, backward, bottom, top, front, rear, etc., for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the invention in any form. Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0019] See Figure 1 , Figure 2 As shown in the preferred embodiment, the waterproof structure of the elevator door opening of this utility model includes, from bottom to top, a concrete structural floor slab 1, fine stone concrete 2, a first waterproof layer 3, a pavement layer 4, and a threshold stone 5. In the outer corridor on one side of the elevator door opening, a second waterproof layer 6 and a third waterproof layer 7 are laid from top to bottom. There is a certain interval between the second waterproof layer 6 and the third waterproof layer 7. The first waterproof layer 3 and the third waterproof layer 7 are connected to each other and overlap and extend.

[0020] Furthermore, the first waterproof layer 3 and the second waterproof layer 6 are both polymer cement waterproof mortar layers, the third waterproof layer 7 is a polyurethane waterproof coating layer, and the paving layer 4 is a dry-hardened cement mortar layer. Dry-hardened mortar has poor fluidity, is not easily deformed, and is more convenient and quick to construct. The longitudinal section of the fine aggregate concrete 2 is a right-angled trapezoid, and the head of the fine aggregate concrete 2 near the elevator shaft is located at a higher position.

[0021] In terms of specific construction, a trapezoidal fine aggregate concrete 2 is installed at the upper part of the concrete structural floor slab 1 at the opening, with a thickness of 30mm near the corridor side and 85mm near the elevator side, a top width of 60mm, and a bottom width of 200mm. A polymer cement waterproof mortar layer is placed on top of the fine aggregate concrete 2. The polymer cement waterproof mortar layer connects with and overlaps with the polyurethane waterproof coating layer at the outer corridor. A dry-hardened cement mortar layer is laid on top of the polymer cement waterproof mortar layer, and a threshold stone 5 is laid on top of the dry-hardened cement mortar layer. The threshold stone 5 is 5mm higher than the corridor floor and has a beveled angle. The joint between the corridor floor and the threshold stone 5 is sealed with sealant 8.

[0022] This structure, consisting of threshold 1, dry-hardened cement mortar layer, polymer cement waterproof mortar layer, fine stone concrete 2, and concrete structural floor slab 1, forms an integrated waterproof structure. This structure can prevent water from entering the elevator from the exterior corridor surface and also prevent moisture trapped in the mortar layer beneath the exterior corridor floor from seeping into the elevator shaft through capillary action, thus achieving a double waterproofing effect.

[0023] The above merely describes preferred embodiments of the present application, and is not intended to limit the implementation and protection scope of the present application. For those skilled in the art, it should be understood that any equivalent substitutions and obvious changes made according to the content of the present application and drawings should be included in the protection scope of the present application.
