Connecting method of metal roof plate and gutter and waterproof eave water baffle plate

Abstract

The invention discloses a connecting method of a metal roof plate and a gutter and a waterproof eave water baffle plate. The waterproof eave water baffle plate comprises a top cross plate, a plurality of top plugging structures and a left vertical plate. The top plugging structures are arranged on the upper surface of the top cross plate to form a peak and valley structure matched with the metal roof plate in shape. The left vertical plate is connected with the left end of the top cross plate, and a left side face of the left vertical plate is matched with a first daub layer on a gutter side plate to form a first sealing structure between the water baffle plate and the gutter. A second daub layer is coated on the upper surfaces of the plurality of top plugging structures and the exposed upper surface of the top cross plate, and the metal roof plate is supported on the second daub layer to form a second sealing structure between the water baffle plate and the metal roof plate. The connecting method of the metal roof plate and the gutter and the waterproof eave water baffle plate can fully meet requirements of a metal roof for waterproof and moisture-resistant performance and solve the technical problem that water of the gutter seeps towards the inner side of the metal roof plate.

Description

technical field [0001] The invention relates to the field of building prefabricated parts, in particular to a method for connecting a metal roof panel and a gutter and a waterproof cornice water retaining plate. Background technique [0002] Metal roof refers to the roof form that uses metal sheet as the roof material and combines the structural layer and waterproof layer into one. It is a new type of composite roof. Its products are used in large public buildings to factories, warehouses, and residences. [0003] The metal sheets used in metal roofs are called metal roof panels. There are many types of metal roof panels, including zinc sheets, galvanized sheets, aluminum alloy sheets, aluminum-magnesium alloy sheets, titanium alloy sheets, copper sheets, and stainless steel sheets. The thickness is generally 0.4 ~ 1.5mm, and the surface of the board is generally painted. [0004] figure 1 It is a schematic diagram of the cooperation between the metal roof panel and the g...

Problems solved by technology

[0008] 2. The liquid has a certain wettability. Although the metal roof panel has an inclination angle, a small part of rainwater will still soak into the edge of the metal roof panel, thus affecting the humidity inside the metal roof panel

[0009] In order to solve the above problems, the existing technology adopts the cornice water retaining plate between the metal roof panel and the gutter, Figure 7 A schematic diagram of the installation of the existing water barrier, such as Figure 7 As shown, the structure of the existing water retaining plate cannot well adapt to the peak and valley shape of the metal roof panel, and there are still gaps at the joint with the gutter and the metal roof panel, which still does not fully meet the waterproof and moisture-proof requirements of the metal roof panel. sex

[0010] Therefore, the structure of the existing metal roof panels cannot fully satisfy the waterproof and moisture-proof properties of the metal roof and needs further improvement.
