Three important characteristics of Gutter groove waterproof

Three important characteristics of Gutter groove waterproof

In roofing,Gutter groove waterproof has always been the “focus topic”, blockage, cracking, deformation and so on, a series of reasons caused gutter leakage of various situations. Why is the leakage of gutter always recurring? Why is the waterproofing of gutter eaves always curing the symptoms but not the root? The key is whether the basic characteristics of gutter structure are really understood.

At present, there are three kinds of commonly used roof materials: 1. steel gutter with 3-6 mm thickness; 2. stainless steel gutter with 0.8-1.2 mm thickness; 3. color steel gutter with 0.6 mm thickness; 4. PVC rain gutter.

Different materials, the scope of application will also be different, so the waterproofing pressure will also be different. For example, stainless steel trenches are commonly found in coastal areas and near projects where there are strong corrosive gases, while color-plate trenches are mainly used in steam building external trenches and projects with small engineering area and small drainage, usually used as external trenches. PVC gutter is mainly used for families.

Therefore, the basic condition of waterproofing depends on the reliability of construction and installation of gutter structures.

1. Steel gutter

The bottom of the trench and the top of the column are welded intermittently, and the bottom of the trench and the top of the column are welded and fixed to increase the overall firmness. It can also be secured by wire rope and wall beam or gutter bracket.

The key lies in the treatment of the nozzle. When opening the hole, attention should be paid to the position of the support and avoid it as far as possible so as to reduce the amount of fittings of the downspout. For the welded metal which is obviously higher than the gutter, grind until it is basically flat. In order to prevent the occurrence of water accumulation at the nozzle, a big hammer can be used to smash the nozzle down a bit, so as to facilitate drainage.

As for paint, attention should be paid to whether the welding slag is cleaned up. If the welding slag is cleaned by iron brush, it should be remembered to use rust-proof paint to repair it. At the same time, a neoprene rubber should be painted on the inside of the steel plate trench for anticorrosive treatment.

2. Stainless steel gutter

The basic installation and opening requirements are roughly the same as steel plate gutter.

We should pay attention to the fact that the stainless steel trench is formed by folding, so there is inevitable size deviation. Try to adjust the gap at the junction to a minimum.

If the gap is too big to be fully welded with welding wire, the edge filler can be used for splicing. Attention should be paid to the welding around the splicing point, while ensuring that the edge filler without leakage welding.

3, color steel plate gutter

Generally speaking, there are two parts for fixing the color plate gutter: 1. The inner gutter plate is connected with the roof panel by self-tapping nails or riveted by pulling rivets; 2. The outer gutter plate is first connected by gutter rivets.

The overlap of the board and the board is treated with neutral sealant. Pay attention to the cleaning of the overlap surface. After gluing and standing for a period of time, the gel solidification can move.

In fact, the key to waterproofing foundation of gutter eaves is the quality of the structure, the quality of the structure is guaranteed, and the waterproofing effect can be guaranteed naturally.
