Steel plant leaking cause and harm

Source: Time:2016-01-19 08:44:28 frequency:

Steel plant water seepage, leakage phenomenon will reduce the corrosion resistance of steel components and reduce the service life of steel plant, long-term seepage, leakage will cause problems to the structural safety, so once the leakage phenomenon should be promptly dealt repair of steel membersIt should also be long-term maintenance to extend the service life of steel plant. Kelly Hang Xiao Bian today appear to share the location and cause leaking to avoid in future construction.

Kelly Hang Xiao Bian today appear to share the location and cause leaking to avoid in future construction.


The site is mainly due to leaking roof at the crest is too high, can not protect the waterproof roof cover, longitudinal lap unpaved waterproof, there are gaps and leaks; roof cover longitudinal lap with rivet connection, insufficient strength after thermal expansion and contraction pull off the rivets, forming leakage; no plug is provided between the roof and the roof cover, or the plug is not required to put off the formation and leakage.

Steel plant roof - lighting board site

Lighting board parts water is an important part of maintaining the system waterproof, lighting panels installed in the cement laying, waterproof roofing screws is a major risk of water leakage. Lighting plate board type does not match with the roof plate, lighting board on both sides of the crest above the roof, after installation, the seal is formed over the strict air pressure difference inside and outside lighting board, lighting board capillary water from both sides of the slit into the interior roof leaks; lighting board longitudinal lap length is not enough, and the loss of sticky clay aging; longitudinal clay off; between the light color steel plates and rigid lap, the gap between the unsealed like.

Steel plant roof - eaves site

The main source of water leakage problem cornice, which is mainly due to leaking parts: the outer panel roof installation does not add foam plug, not under the roof outer plate pull; inadequate length of the wall outer panel and the cornice parts revenue side did not add water.

Steel plant Roofing - Gutter site

Gutter insufficient depth

None Gutter slope

Gutter water intrusion

Number of insufficient rain bucket

Since the steel plant gutter from steel plate from repression, gutter board uneven slope difficult to process, easy to water, the water discharged by the hydraulic gradient only water to produce water bucket, so gutter drainage is slow, causing rapid Gutter draft increased. Although the specification mentioned gutter slope should ensure aid 0 3%, but by limiting process in practice, steel gutters difficult to achieve the slope. Under the current situation is more simple and practical approach is to encrypt water bucket arrangement, in order to avoid the rain gutter along the flow distance away, a long time, resulting in backwater.

Steel plant - Yupeng site

The site is mainly due to leakage between the interface part of the processing room awning and attached properly, is not provided between the plug and the exterior awning design requirements or fails to extend into the interior and exterior panels.

Steel plant - Aluminium windows site

Aluminum windows and color-coated steel wall and brick wall joints is one of waterproofing problems, mainly due to the leakage site: between the wall purlins and aluminum there is a gap; under Windows port and steel, brick wall and windows Mifengbuyan between glass and profiles; the presence of the large gap with Taiwan windowsill or fall back to the water phenomenon; windows catchy pan of water without making the income side mounted in waterproof.

Steel plant - material improper selection

(1) rainwater pipes with plastic pipes, poor strength, steel plant from installation to put into operation, easily damaged.

(2) Since the thin steel sheet gutter, the weld prone to problems.

(3) did not choose the right lighting panel according to the roof slope and roof plate color plates of the plate, the peak is smaller, lateral overlap too little, is not conducive to drainage.

(4) Retaining part color plates is too thin, after a period of use, the outer plate corrosion or affected by temperature increases the gap between the deformed plates.

(5) pressure plate substrate of poor quality zinc coating, the coating is too thin, causing the pressure plate life is short, easy to rust damage.

(6) self-tapping screw pads poor quality prone to cracking, glass sealant is easy to aging.

(7) significant deformation pinch two adjacent plates plate high pitch are different, pinch screws should be waterproof Rivet
