Detailed Product Description: | An Qingjie green companies, professional wall cleaning, professional external walls trap company. I. Introduction Block the invasion of wind and rain dew, for the building is a major function. Since ancient times, water penetrate from the roof, walls or floor around the world have been put in a lot of thought. With the development of reinforced concrete structures, a large number of flat roofs, making the roof waterproof "or" flat roof waterproofing technology is developed. However, the wall has not been application of the so-called waterproof exterior cleaning company in Changping Changping external walls trap only to the external wall decoration or dry concrete to meet the waterproof function! In recent years, full of continuously reinforced concrete caused by leakage water of the external walls of buildings, such defects, leaks are handling adverse. Leaks will cause pollution, discoloration, mildew, corrosion and other undesirable phenomena. Which led to bad rust due to water absorption, resulting in the reduction of thermal insulation properties, as well as condensing the second defect. The case of these leaks, non-industry from the roof but from the walls, exterior cleaning company in Changping Changping external walls trap, of which there are many reasons, but the main reason is not yet done on the external wall fully taken into account , just the idea of ??"rain" to correspond to this problem. Thus, with the change of building the size, shape, detail, practices and external wall materials, in the past does not constitute a problem detail and materials, often formed not able to meet the circumstances of the waterproof function. Described in this article, only the external walls of rain, leaking the formation of the type of external wall leaks and waterproof external wall surface to provide a reference Dongguan Changping cleaning company / / Changping wall cleaning company / / the flat floor cleaning company Are described as follows: (A) the external walls of the rain If it rains, wind, rain will sweep the wind is stronger, the rain is even less close to the level of this reason, the outer wall would have been exposed to rain. The external walls of leaking phenomenon, is the original solid external walls have been directly exposed to rain or poured into the walls of prominent parts of the rain reached the wall and shed. The rain of the wall, exterior cleaning company in Changping, often flat external wall trap not only by the wind speed and rain directly about, of course, the building shape, height, location will result in different situations. In general, the rain when it rained, was with the increase in air resistance and speed, when this resistance line and the acceleration due to gravity after the rain with constant speed drop, in any case, as long as the wind speed reached 7 ~ 8m/ser, vertical and the horizontal plane should have been a lot of rain; when wind speed reaches 15m/ser vertical than horizontal rainfall suffered twice as large. If the wind direction when the drastic changes along the wall, the rain easily run into walls, small rain wind falling due to the easy and difficult conflict to the wall. (B), the formation of leaky Pouring rain to the wall, due to the collision leaving part of the "flying", while another part is absorbed from the surface of the wall to wall materials, the rest stay within a short time there is a lot of rain poured into the wall almost most of the material surface layer will reach saturation, and the stagnation of rain water will also increase, will be the formation of water droplets in the surface move. If the rainfall continues to increase, will form the membrane and the movement of the strip. Exterior cleaning company in Changping Changping external walls trap rain moving in the direction, and is not limited to below the moving rain, such as the end of the prominent parts of the water droplets falling, flying arising from "stripping the water of the site will caused by the stripping of water droplets or water film. The above phenomena in a variety of circumstances will cause infiltration of rainwater from the wall to the interior, so shower wall rainwater penetrate indoor, after the move, the formation of leaks. Dongguan Changping cleaning company / / Changping wall cleaning company / / the flat floor cleaning company (C), the type of external wall trap A, on-site poured set of concrete 1, concrete cracks Set the scene pouring the concrete layers have continued filling seams or cold then, prone to the bad part of cellular or filling, the formation of congenital shrinkage cracks. In particular, the large span of the wall or protruding from the wall structure of continuous spinal wall, this situation is more common. Two parts of the continued irrigation with cold then Continued irrigation parts and cold layers then bound effect can not be expected between the concrete, often a flat exterior cleaning company, often flat external wall trap was a small earthquake and concrete shrinkage, joint will be cut off to form easily produce the leaky situation. 3, around the openings Not limited to the concrete structure around the openings of waterproof construction, easy to a weakness of the site. Note windowsill can, however, occasions, posted after the stucco decoration or tile the windows will appear around the top of the cement floating bar or debris, voids, concrete pouring concrete or tile template pre-paste construction method of the occasion, horizontal or reverse slope, and other circumstances, a site full of shortcomings. B, the ALC board and cement bricks 1, the ALC board joints around Water permeability and water absorption of the ALC board, low intensity, and fragile, without proper sealing material, often flat exterior cleaning company, often flat external wall trap so often from the seams leaking. Against the deformation capacity is too weak, even a slight movement can cause the ALC board cracks in the cement mortar filling parts, and leaking from there, the ALC board in handling the installation and its surrounding commonly prone to defects, if the patch not appropriate in the short run will be stripped patched with cement mortar joints internal will infiltrate stormwater. Third, the conclusion In recent years, the leaking of the external walls of the growing incidence of second defect of the interior space of buildings, this is not only unsightly and health, and serious impact on construction safety. Economic growth, people's living standards rising, waterproof design of the building can not afford is still stuck in the rain "stage; pay attention to and enhance the living quality of the environment, to be on the architectural design should have a complete planning, from the base. to design, structural calculations, construction quality control and the use of management, should indeed do a good job, and shall focus on the external walls of water engineering considerations to ensure that residential safety and health. |
