Description

[Technical field]

[0001] The utility model relates to the technical field of prefabricated component production, and more specifically, to a large-span water-proof assembled building concrete prefabricated double T-plate. [Background technology]

[0002] With the rapid development of the construction industry and the continuous improvement of people's requirements for building quality, prefabricated buildings have gradually become the new favorite of the construction industry with their advantages of high efficiency, environmental protection and energy saving. Among them, prefabricated concrete double T-plates, as an important structural component, are widely used in various construction projects. Double T-plates have good structural mechanical properties, clear force transmission levels, and simple geometric shapes. They are a kind of load-bearing components that can be made into large spans, large coverage areas and are relatively economical. In single-story industrial plants, double T-plates are used as roof panels, which can be placed horizontally on support beams or load-bearing walls, or longitudinally on roof beams, and can also be installed vertically on strip foundations as wall panels. Traditional concrete double T-plates are widely used in the construction industry, but due to their poor waterproof performance, they are prone to leakage problems in humid or underwater environments, affecting the safety and service life of the building.

[0020] See also Figure 1 , Figure 2 In the embodiment of the utility model, a large-span waterproof assembled building concrete prefabricated double T-plate includes a plate body 1, a support beam 2, a guide plate 5, and a water collection group 6. The bottom of the plate body 1 is symmetrically provided with a support beam 2. The outer surfaces of the plate body 1 and the support beam 2 are provided with a waterproof layer made of polyurethane, acrylate, and silicone. A reinforcing rib 3 for increasing strength is provided between the plate body 1 and the support beam 2. The inside of the plate body 1 is penetrated by a reinforcing rib 4. A lifting ring is provided on the top of the plate body 1 for easy lifting and movement. A guide plate 5 is provided on the top of the plate body 1. The surface of the guide plate 5 is coated with a waterproof material. The middle of the front side of the guide plate 5 is two high. The side of the guide plate 5 is low, and the side away from the drain outlet 62 is high, so that water can be guided into the water collecting group 6. The water collecting group 6 is connected to the water collecting group 6 on both sides of the guide plate 5.

[0021] Working principle:

[0022] The utility model discloses a large-span waterproof assembled building concrete prefabricated double T-plate in use. When it rains or there is high humidity, water vapor first reaches the guide plate 5 on the top of the plate body 1. Since the guide plate 5 is high in the middle and low on both sides, the water vapor is guided to the water collecting groups 6 on both sides. At the same time, the side of the guide plate 5 away from the drain port 62 is high, and the water collecting trough 61 is also high on the side away from the drain port 62, so the water vapor can be guided to the side of the drain port 62. The drain port 62 leads the water vapor out through the drain pipe 63. Since the drain pipe 63 is longer than the thickness of the plate body 1, it can be ensured that the water vapor does not contact and erode the side wall of the plate. At the same time, the plate body 1 and the support beam 2 are provided with a waterproof layer, and the guide plate 5 is coated with a waterproof material to avoid water vapor erosion.

[0023] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
