Design principle of eaves gutter Detailed explanation of installation steps of eaves gutter

We know that the roof needs drainage. Of course, there are many drainage methods on the market. Whether there is tissue drainage is very important. Of course, this roof drainage method is implemented according to the actual situation. How to install and design the gutter on the roof is really important. This rainwater drainage is related to the whole drainage system, and the drainage design also needs to know the whole appearance. Good design can improve the service life of the building and have some beautiful decorations.

Design principle of cornice drainage trough

(1) In general, there should be no less than two drainage outlets on each roof or gutter.

(2) Generally, the distance between two rain outlets should not be greater than the following data: Is there a gutter? 24m without eaves gutter and internal drainage? 15m

(3) The center of the rain mouth shall be not less than 0.5m from the inner edge of the end parapet.

(4) The roof assembly line should not be too long, and single slope drainage can be done when the roof width is small; Is the roof wider? If 12m or more, double slope drainage should be adopted.

(5) Estimate the impact load according to the rainfall amount of each impact, excluding the roof catchment area of 150-200m2. What time? When the roof has a height difference, if the catchment area of the high roof is less than 100m2, can the rainwater from the high roof be directly discharged to the low roof? Let's go If there is any unorganized drainage, a layer of coiled material should be laid on the part of the low-span roof washed by water, and C20 concrete slab with a width of 300-500mm should be laid to strengthen protection; For organized drainage, a water dustpan should be added under the downpipe. Like what? When the area of high-rise roof is greater than 100, the high-span roof should form its own drainage system.

(6) The eaves gutter or gutter should have a longitudinal slope, so that the rainwater in the gutter can be quickly discharged to the impinges mouth. The longitudinal slope gradient should not be less than 65438 0%, the gap at the bottom of the ditch should not exceed 200mm, and the drainage of eaves gutter and gutter should not flow through deformation joints and firewalls. With lime, for example? Slag and other light materials are placed on the slope.

(7) The net width of the gutter is not less than 200mm, and the minimum depth of the watershed is greater than 120mm.

(8) There are several diameters of downspouts, such as 75mm, 100mm, 125mm, etc. , the inner diameter of the storm sewer is not less than 100mm? Pipes include cast iron, cement, plastics, ceramics, PVC, etc. The installation distance of the downpipe from the wall should not be less than 20 mm. The pipe body is fastened with pipe hoops, and the vertical spacing of the pipe hoops is not more than 1. Two million.

Detailed explanation of installation steps of cornice drainage trough

1. Level the installation position of the rainwater tank, and use ink lines to play lines from beginning to end.

2. Take out the rainwater tank from the packaging bag, put the rainwater tank on the ground or scaffold smoothly, and put it in the rainwater tank.

Install the rainwater hopper in the water, and cut a hole with the same size as the lower outlet of the rainwater hopper with a cutting machine.

3. Slowly insert the rain bucket into the rain trough to the launching position.

4. Install a hanger on the rain trough; Insert in sequence and master the spacing, and the distance between two adjacent hooks is 40 ~ 50cm；;

5, with an electric drill (No.6 drill) in the elastic line position according to the spacing of 40 ~ 50 cm, knock into the expansion tube.

6. Place the rain gutter at the position of elastic line, adjust the spacing of "hanger", and then fix the hanger and rain gutter on the cornice with corresponding stainless steel screws.

7. When encountering the corner of the rain gutter, the "external corner" and "internal corner" need to be connected by "connector" (note: double walls are not used), and the connecting part between the rain gutter and the rain gutter also needs to be connected by "connector".

8. In the installation process of the gutter, in order to prevent water leakage, the corresponding locking devices, clamping devices and other accessories must be marked with silica gel.

9. The cross slope of the lower outlet should be kept at 5- 10 degrees, which is beneficial to smooth drainage.

10, when the radian of ceramic tile is large, try to place rain buckets within 10 meter.

Every house knows the installation design of the gutter, or every building needs to consider how to drain water. The drainage condition is to choose the appropriate drainage method according to the actual situation. How to install the gutter is here to share with you. Of course, the installation price of the gutter is different, and the price is different in different situations. Specifically, it is necessary to find a suitable construction team according to the actual situation. If you still want to know about the gutter,
