Description

Color steel tile roof waterproof structure

technical field

The utility model relates to a roof waterproof structure.

Background technique

Building waterproofing is a sub-project to ensure that the structure of a building or structure is not invaded by water, and the internal space is not harmed by water. Building waterproofing plays an important role in the whole construction project. House roof waterproofing in building waterproofing engineering is a systematic project. Over the years, roof leakage has been one of the most prominent quality problems in house construction, and it is also a difficult problem that has not been well solved for many years. Roof leakage into the room will not only seriously affect people's quality of life and living standards, but also directly affect the normal use and durability of buildings.

House construction has done a lot of research on roof leakage prevention since ancient times. Among them, roof leakage is the most influential factor in terms of the durability of the house and the function of meeting normal use. Residential roof leakage makes residents extremely disgusted, and factory building leakage sometimes causes heavy losses, especially the anti-leakage of grain warehouses is more important. Once some roofs leak, it is quite difficult to repair.

Color steel tile is a form of roof waterproofing that has emerged in recent years. The installation speed of color steel roof is fast and the waterproof effect is good. However, the leakage problem caused by color steel plate has also appeared many times in recent years. The reason is that there will be dust in the gutter form of the color steel roof, which will cause the metal of the color steel to corrode and cause leakage. At the same time, the bolts for installing nodes will deform the color steel plate during the fastening process, and the bolts and gaskets for installing nodes will lose their effect. These factors will also cause leakage. Among them, the most important parts of the color steel roof leaking are concentrated in the overlapping joints of the profiled plates, the roof lighting belt, and the connection between the gutter steel plate and the cement wall. For flat roofs, two-felt-three-oil or three-felt-four-oil roofs were usually used for waterproofing in early buildings. Most of the leaks on this type of roof were caused by flooding and excessive area, and the waterproof layer cracked and leaked. This kind of material is no longer used now, and it is only encountered during repair and maintenance. Due to the unstable product quality, there are many hidden dangers in the use of SBS coils that are commonly used now, and the main leakage point is flooding and cracking. The latest SCB120 polyethylene polypropylene fiber composite waterproof membrane is the waterproof membrane after SBS. This product has advantages in effect and cost accounting, but this product has higher requirements for construction quality. For the color steel tile roof that is widely used now, the reasons for the leakage generally have the following aspects. First of all, the thermal conductivity of the metal plate itself is large. When the external temperature changes greatly, due to the large change in the ambient temperature difference, the color steel plate shrinks and deforms due to the temperature change and produces a large displacement at the interface, so it is very easy to generate heat at the interface of the metal plate. Water leakage hazard. Secondly, due to the use of different materials to connect special parts, such as the joint between the parapet wall and the wall made of steel plate, the roof lighting belt and other parts, due to the asynchronous stress change, there is a hidden danger of water leakage. Finally, because the building structure itself is prone to elastic deformation under the action of external forces such as temperature changes, wind loads, and snow loads, the displacement of the connection parts will cause hidden dangers of water leakage.

Utility model content

The purpose of this utility model is to solve the problem of the leakage zone caused by the displacement and deformation of the overlap between the color steel plate and the color steel plate or the cracking of the joint between the color steel plate and the cement wall of the existing color steel tile roof, and then provides A color steel tile roof waterproof structure.

The technical scheme that the utility model adopts for solving the problems of the technologies described above is:

Technical Solution 1: A color steel tile roof waterproof structure, including a composite material layer, a middle coat and a top coat, which are sequentially arranged at the joints of the color steel plates from the inside to the outside, and the thickness of the composite material layer ranges from 1mm to 3mm , the composite material layer includes a backing substrate layer and an adhesive material layer, the backing substrate layer is a non-woven fabric layer, and the adhesive material layer is made of chlorinated butyl rubber, polyisobutylene, tackifying resin and nano-scale calcium carbonate Layers of composite adhesive material.

Technical solution 2: A waterproof structure of a color steel tile roof, including an adhesive material layer and a backing base material layer sequentially arranged at the overlapping joints of the color steel plates. The adhesive material layer is chlorinated butyl rubber, polyisobutylene, tackifier The composite adhesive material layer is made of resin and nano-scale calcium carbonate, and the backing substrate layer is an aluminum foil layer.

Compared with the prior art, the utility model has the following effects:

For the waterproof structure of technical solution 1, during construction, it is only necessary to paste the composite material layer on the joint between the color steel plate and the color steel plate to be treated or the joint between the color steel plate and the cement wall, and then paint it after it is firmly sealed. Middle coat, after the middle coat is dried and formed into a film, then apply the top coat. The middle coat and top coat can effectively improve the water resistance, weather resistance and oxidation resistance of the waterproof structure;

For the waterproof structure of technical solution 2, during construction, it is only necessary to paste the composite material layer on the connection between the color steel plate and the color steel plate to be treated or the connection between the color steel plate and the cement wall, and then stick it firmly and seal it.

The above two technical solutions are all aimed at the connection between the color steel plate and the color steel plate or the connection between the color steel plate and the cement wall. Compared with the existing waterproof structure, the waterproof effect of the connection is better.

The waterproof structural material of the utility model is simple, convenient in construction, low in cost, long in service life, excellent in weather resistance, oxidation resistance, fatigue resistance, aging resistance, low temperature flexibility and excellent elasticity. Used during the first construction, it can basically guarantee the same service life as the roof panel. The utility model can withstand a certain degree of deformation, has strong plasticity, and reduces the influence of the displacement deformation of the overlapping joint between the color steel plate and the color steel plate or the cracking of the joint between the color steel plate and the cement wall on the sealing and waterproof performance of the joint.
