Description

Technical Field

[0001] The utility model relates to the technical field of rainproof thresholds, in particular to a rainproof threshold structure of a building. Background Art

[0002] For engineering projects, we all know that in addition to the waterproofing of roofs and walls, the waterproofing of some equipment rooms is also very important, just like the heart. Once there is a problem with the "heart", the entire building and even the city will be paralyzed.

[0003] At present, due to the settlement of the foundation or the continuous elevation of urban roads, the existing cultural relics buildings usually have no height difference between the indoor and outdoor areas, and the outdoor area is even higher than the indoor area. However, the power distribution room and the fire control room are often located on the first floor. The common practice is to change the height of the door or use a finished rainproof threshold, but both methods have certain disadvantages. The former usually affects the appearance of the building facade because of the change of its facade opening, while the latter is difficult to ensure the rainproof effect.

[0004] Therefore, in view of the above problems, a new type of building rainproof threshold structure needs to be designed to solve the above problems. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rainproof threshold structure of a building, comprising a bottom foundation, the upper end of the bottom foundation is fixedly connected to a plain brick wall, a door frame is opened on the plain brick wall and a plain concrete threshold is cast on the bottom foundation at the bottom end of the door frame, and a steel plate waterstop is pre-buried inside the connection between the bottom foundation and the plain concrete threshold.

[0007] As a preferred technical solution of the utility model, extended thresholds are arranged on both sides of the plain concrete threshold, and the extended thresholds are cast and connected to the inner wall of the exposed brick wall.

[0008] As a preferred technical solution of the utility model, a concrete casting layer is cast in front of the plain concrete threshold at the upper end of the bottom foundation, and a door sill is laid above the concrete casting layer.

[0009] As a preferred technical solution of the utility model, two double doors are symmetrically arranged above the threshold, and the two double doors are movably connected to the two side walls of the door frame respectively.

[0010] As a preferred technical solution of the present utility model, an anti-static raised floor is laid on the ground on the indoor side of the plain concrete threshold, and a plastic composite board skirting board is attached to the wall body on the indoor side of the plain concrete threshold.

[0011] As a preferred technical solution of the present utility model, an interior wall plastering layer is painted on the wall of the fair-faced brick wall indoors.

[0012] As a preferred technical solution of the present utility model, a ground paving layer is laid on the ground of the outdoor wall of the fair-faced brick wall, and the ground paving layer is connected to the plain concrete threshold.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By adopting a C20 plain concrete threshold, the present utility model is simpler and faster in construction compared with a reinforced concrete threshold. It does not require complex processes such as steel bar binding and welding. At the same time, it has certain waterproof and moisture-proof properties, which can effectively prevent moisture from penetrating into the room or other areas from the threshold. The steel plate water stop belt provided inside the connection between the bottom foundation and the plain concrete threshold can further improve the waterproof performance of the rainproof threshold, and the working life can be not less than the design working life of the engineering structure. It is economical and durable, meeting the style requirements to the greatest extent and also meeting the water blocking function. BRIEF DESCRIPTION OF THE DRAWINGS
