Embodiment 1

[0047] see Figure 1 to Figure 3 and Figure 5 to Figure 6 , The present embodiment provides a seam leak-proof structure for a prefabricated roof panel, which includes a first leak-proof layer and a second leak-proof layer. The first anti-leakage layer includes two sets of flexible structures 2, and the two sets of flexible structures 2 are respectively arranged on the main ribs 11 of two adjacent roof panels 1, that is to say, the two sets of flexible structures 2 are arranged on two adjacent roofs. At the butt joints of the main ribs 11 of the panels 1 , the second leak-proof layer is filled between the joints of two adjacent roof panels 1 and is located above the flexible structure 2 .

[0048] Specifically, for any set of flexible structures 2, such as Figure 5 to Figure 6As shown, it includes a main body portion 20 and a convex portion 21. The main body portion 20 is L-shaped and includes a pad portion 201 that is padded at the bottom end of the main rib 11 and an exte...

Embodiment 2

[0052] see Figure 1 to Figure 6 , A prefabricated roof panel 1 provided in this embodiment includes a roof panel body 10 , a main rib 11 , an end rib 12 , a reinforcing rib 13 and the plate seam leak-proof structure in the above-mentioned embodiment 1. The main body 10 of the roof panel is a rectangular roof panel, which is composed of a light steel outer frame around it and a concrete structure layer filled in the light steel outer frame. , there is no detailed description and limitation. Those skilled in the art can choose the composite core according to actual needs. For example, the composite core can include a thickness of 30cm and a density of 500kg / m 3 The core board is 48cm thick and has a density of 300kg / m 3 The core board and the thickness of 20cm, the density of 500kg / m 3 The core board is laminated up and down, such as Figure 4 As shown, the steel bar 4 includes a plurality of steel bars, and the plurality of steel bars 4 are arranged in parallel and perpendi...

Embodiment 3

[0055] see Figure 1 to Figure 6 , A prefabricated roof panel system provided in this embodiment includes a plurality of prefabricated roof panels 1 in Embodiment 2, and is formed by splicing a plurality of prefabricated roof panels 1 in Embodiment 2.

Abstract

The invention relates to the technical field of construction engineering, and discloses a leak-proof structure of a prefabricated roof panel, a prefabricated roof panel and a roof panel system, wherein the leak-proof structure of the panel seam includes a first leak-proof layer, a first leak-proof layer It includes two sets of flexible structures, which are arranged in contact with each other at the joint between the main ribs on the long sides of the roof panel and the main ribs on the long sides of the adjacent roof panels; any set of flexible structures includes a main body that is sealed and bonded to the main ribs and At least one of the convex parts fixed on the main body protrudes toward the seam and can be closely abutted on another group of flexible structures. In the chamber layer, the air pressure of the air chamber layer is higher than the outside air pressure, so as to prevent the liquid at the bottom of the seam from penetrating into the air chamber layer and entering the chamber. It has good waterproof performance, the flexible structure is sealed and connected with the main rib, and it is not easy to fall off, which solves the problem that the mortar is easy to fall off in the existing waterproof method of filling mortar, resulting in poor waterproof performance.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a plate seam leak-proof structure, a prefabricated roof panel and a prefabricated roof panel system. Background technique [0002] Prefabricated decoration is an emerging form of decoration construction in recent years. As the name implies, prefabricated decoration is to complete the production of various parts and components required for decoration in the factory, and then transport them to the decoration site for combined installation, eliminating the need for the traditional decoration site to measure and cut each part. The construction is simpler and more convenient, which can greatly improve the construction efficiency of the decoration site, and the construction site is more tidy and beautiful, and will not generate too much decoration material waste, which is a more green and environmentally friendly decoration construction form. [0003] The prefabricate...
