Waterproofing of buildings is a worldwide problem. In fact, the advantages of building waterproofing quality are not merely the construction management and construction techniques. The key is material. We should reconsider the basic theory of building waterproof materials and building waterproofing, and we must unify the two to find a more complete solution. If only from the waterproof point of view, the principle of waterproofing is very simple, as long as the impervious material can waterproof, the key to building waterproofing is to connect the impervious material into one, making it a continuous, overall Waterproof layer, so as to achieve the overall waterproof effect of the building. At the same time, it must also be taken into consideration that the waterproof period of the building should be synchronized with the life of the building, as well as the dynamic factors such as the deformation of the basement of the building and the settlement of the building. If the architectural waterproofing design takes into consideration the above factors, the problem of waterproof quality can generally be better resolved.
In today's modern housing industry, the waterproofing of lightweight steel-framed houses is more difficult than waterproofing of concrete structures because once leakage occurs, it directly affects the useful life of the house. At the same time, the construction of steel structures still has Anti-corrosion requirements, so more attention should be paid to the issue of waterproof.
First, the choice of materials 1. "Waterproof material waterproof performance" generally should not be compared with other material properties, the key to good or bad material, compared with the performance of its own material, we can determine the waterproof material waterproof performance excellent. The waterproofing of buildings is to form an integral waterproof layer on the site. The monolithic waterproof material produced in the factory must be bonded into a waterproof layer as a whole. Therefore, the “waterproof function†requires that the waterproof material be adhered to the base surface. The adhesive force with the base surface must be greater than the strength of the waterproof material itself, otherwise, the deformation force distance and the deformation range are all concentrated on the adhesive at the time of thermal expansion and contraction deformation, which may easily cause cracking and cause the overall failure of the waterproof layer.
2. The waterproof material does not have to pursue its strength, the key requirement is to increase the elongation rate of the waterproof material. When the substrate is deformed, the waterproof material overcomes the "internal force" by extending to maintain good overall waterproof performance. Therefore, it is reasonable to choose a waterproof material without a tire base. For example, TBL has no tire base, polymer membranes, etc.
3. The shear strength of waterproof material is the main technical indicator of buried waterproof. When the upper and lower two layers of hard rakes sandwich the waterproof layer, the water-proof layer cannot be extended to satisfy the deformation. Therefore, it is appropriate to choose a waterproof material with a large elongation and a linear molecular structure. From this feature, the only waterproof material with the highest elongation rate in the Chinese market is TBL pastein.
4. Buildings are a huge object. They are usually constructed outdoors. They have large management sites, and there are many people entering and leaving the construction site. Most of the building materials and parts that are handled are bulky and need to be transported by trolleys. The general construction site personnel are numerous. For migrant workers with lower levels of education, the concept of love of the product is not strong, and it is not easy to pay attention to the protection of the product as it is produced on the factory floor. In addition, yellow sand and stones will be scattered on the building at any time. Therefore, in the course of walking and cargo transportation, it is easy to destroy the waterproof layer of the building, and a small hole will cause the failure of the entire waterproof layer. Therefore, waterproof material must be overcome by man-made damage. It is essential if the waterproof material can be treated like human skin and it can heal after being scratched. This can avoid artificial damage during the construction process. Currently, only TBL products on the market have the above conditions.
5. The waterproof standard of the light steel structure housing system is higher than that of the traditional concrete structure housing. Therefore, only the watertight waterproof material can be used to meet the waterproof requirements of the light steel structure housing.
One of the modernizations of the housing industry is factory production, which allows boards made from factory production lines to replace blocks, which in turn raises the issue of waterproofing of board seams, and this problem has become a deterrent to the quality of light steel structures. In the 1960s, the large-scale construction that China introduced from the Soviet Union was stopped for promotion in Beijing and other places. The important reason is that the leakage of the board seam causes the loss of the function of the house. At that time, concrete was mainly used as the raw material. The water seepage will not immediately affect the life of the building. Now, the wall of the light steel structure house is basically used for water absorption. Strong organic materials are used as substrates, and in the construction process, metal fasteners and self-tapping bolts are basically used to connect them. There will certainly be many nailholes on the inner and outer walls. How to solve the problem is not solved. It has become a key technology that needs breakthrough in the waterproof treatment technology of light steel house.
Second, after more than ten years of research and development, the waterproof treatment of steel structures has passed tens of thousands of square meters of building tests. Practice has proved that the best solution to the above problems is to improve the structure of the structure and to improve the material. Performance, now we think that the combination of the two waterproof solutions, the most effective, and its specific implementation is as follows:
1. The materials used for exterior wall selection are various types of plates with different materials, and the structure should be selected for waterproof construction. If pvc hanging board is used on the outer wall and fixed with metal screws, the TBL must be used as the integral waterproofing of the outer wall. The superposition of the sheet and the steel structure requires the double-sided adhesive TBL as the self-adhesive self-healing seal. Gas barrier, sound insulation, active damping settings for vibration-damping design.
2. The kitchen door bathroom must be built with integral waterproofing to ensure that the floor and walls do not leak after construction.
3. The basement adopts external protection and waterproof inside. The bottom and wall are connected into a closed box type waterproof. The concrete continuous wall is poured on the waterproof layer to form an inverted box type waterproof, making the basement form an overall seamless. Waterproof body ensures waterproof success rate.
4. If the roof is a flat roof, use TBL inverted waterproof, such as inclined roof can use TBL to make roof functional waterproof layer, and then set other decorative layers on the waterproof, color linoleum tile, metal tile, stone roof tile, etc. Secure with metal nails.
5. Ventilation pipe, water pipe, in addition to the conventional connection outside the waterproof connection can be used TBL tape banding for several times as a strengthening treatment, its effect is better, waterproof and more secure and more secure.
It is important to note that building waterproof is more important because it directly affects the service life of the building. Therefore, new breakthroughs must be made in the waterproof material, and new ideas must be put in the design ideology so that waterproofing is needed. The location and place must be provided with a waterproof layer, so that our buildings will be able to completely solve the problem of water leakage in the world of six leaks.
