Description

Technical Field

[0001] The utility model belongs to the technical field of waterproof and anti-corrosion equipment, and in particular relates to a movable wooden house flat roof and wall waterproof and anti-corrosion device. Background Art

[0002] At present, the current technical status of wooden house waterproofing is mainly based on sloping roof tiles for drainage. Or waterproofing membranes are used to lay sloping roofs. Very few waterproof designs and waterproofing systems are made on wooden structure roofs with flat roofs. The main difficulties are: 1. Wood is easy to absorb water and corrode. 2. Wood has large elasticity and unstable structure. 3. When wood is laid on a flat surface, it is formed by splicing, which is not an integral structure, with many joints and great leakage risks. 4. The wood base surface has poor bonding with ordinary waterproof materials.

[0003] The main problems of existing wooden house waterproofing technology include:

[0004] 1. Water absorption and corrosion of wood: Wood itself is a porous material with strong water absorption. Once the wooden house encounters rain, the wood easily absorbs water and remains wet for a long time, which provides a growth environment for mold and decay fungi, leading to wood corrosion. In the long run, the strength of the wood will be greatly reduced, affecting the structural safety of the wooden house.

[0005] 2. Wood expansion and contraction: Wood is greatly affected by changes in temperature and humidity and is prone to expansion and contraction. In a high humidity environment, wood will expand; in a dry environment, wood will shrink. This expansion and contraction makes the roof structure of the wooden house unstable, and the waterproof layer is prone to cracks due to the deformation of the wood, which leads to leakage.

[0006] 3. Many joints in wood splicing: The roof of a wooden house is usually made of multiple pieces of wood spliced ​​together to form a non-integrated structure. A large number of joints will be generated during the splicing process, and these joints are the weak links in the waterproofing of wooden houses, because it is difficult to completely seal the joints and leakage is likely to occur.

[0007] 4. Poor bonding between wood base and common waterproof materials: Due to the porosity and unevenness of the wood surface, it is difficult for common waterproof materials to form a good bond with the wood base. The waterproof material has weak adhesion on the wood base and is prone to fall off or cracking, resulting in failure of the waterproof layer.

[0008] In summary, the existing wooden house waterproofing technology faces technical problems such as wood water absorption and corrosion, expansion and contraction deformation, joint leakage, and poor bonding of waterproof materials. In order to solve these problems, it is necessary to develop new wooden house waterproofing materials and waterproofing systems to improve the waterproof performance and stability of wood, reduce the risk of joint leakage, and enhance the bonding between waterproof materials and wood base surfaces.

[0018] First, in view of the existing technology, the roof or wall of the traditional wooden structure house is mainly designed with slopes based on drainage design. The design of the utility model is screened and tested by a variety of waterproof materials. The reasonable combination of technical installation steps is used to achieve the enclosed structure of the wood itself. And it can simultaneously enclose the joints between wood and wood, and ensure that the expansion and contraction ductility of the waterproof material is consistent with the expansion and contraction of the wood. The wood will not be soaked in water, the appearance will be deformed, and the structure will not seep due to cracking, aging and bubbling of the material in the later stage. In the process of choosing this system development, different design and construction methods and design and construction steps are used. And different waterproof material combinations, proportions, and experimental products are produced. Different results appear during the weathering test (winter and summer outdoor natural exposure, scorching sun and ice and snow). Through analysis and experimentation, the utility model finally finds the above scheme as the optimal scheme. That is, it can effectively solve the waterproof and anti-corrosion problems of the flat roof of the wooden house structure, and can also effectively resist the durability and weathering requirements. And the construction is relatively convenient and fast. At the same time, it takes into account both beauty and cost. It is used to meet the protection needs of multi-layer outdoor superposition installation of mobile wooden houses, or when installed alone.

[0019] The utility model breaks through the basic application of waterproofing the roof of a wooden structure house, which is mainly in the form of a sloping roof. The flat roof waterproofing design can make the indoor space flatter and reduce the overall height. The space utilization rate is higher. It is also more durable and corrosion-resistant, with better waterproofing effect and better air tightness.

[0020] Second, as auxiliary evidence of the inventiveness of the claims of the utility model, it is also reflected in the following important aspects:

[0021] (1) The expected profit and commercial value of the technical solution of this utility model after transformation is RMB 5 million.

[0022] (2) The technical solution of the utility model fills the technical gap in the industry at home and abroad: the present invention fills the technical difficulties of overall structural waterproofing of the flat roof design of the wooden structure.

[0023] (3) Does the technical solution of the utility model solve the technical problems that people have been eager to solve but have never been able to solve successfully? The utility model solves the technical support difficulties of the evolution of wooden structure roofs from conventional pitched roof designs to flat roof designs. It allows wooden structure houses to be made into durable, waterproof and anti-corrosive flat roofs.

[0024] (4) Whether the technical solution of the utility model overcomes the technical prejudice: The technical solution of the utility model overcomes the technical prejudice that the waterproofing, corrosion resistance, durability and use effect of the wood splicing and nailing roof are not good. It overcomes the technical prejudice that it is more reasonable to design a wooden house with a sloping roof, making the flat wooden roof also a viable option. BRIEF DESCRIPTION OF THE DRAWINGS
