Description

Technical Field

[0001] This utility model relates to the field of timber technology, and in particular to a corrosion-resistant and moisture-proof timber for use in construction projects. Background Technology

[0002] Timber is a widely used building material, commonly used in concrete pouring construction as a support material for formwork, and as supporting columns and beams for building structures. It is also an indispensable material in interior decoration, such as ceiling and wall framing, serving as a supporting structure to fix decorative materials like boards. For example, common gypsum board ceilings are built with timber framing as the base. In construction projects, high-quality timber can be used to make furniture components, such as chair legs, tabletop frames, and sofa frames, providing support and stability. Some solid wood furniture even uses timber extensively as a primary raw material to ensure the quality and lifespan of the furniture.

[0003] Timber has a wide range of uses in daily life, and in places where it is used for a long period of time, the quality requirements are also high. Ordinary timber is prone to rotting in humid environments or attracting insects, leading to a significant decrease in its mechanical properties and affecting structural stability, thus posing safety hazards. Traditional moisture-proofing and anti-corrosion measures for timber usually involve coating the outer surface with anti-corrosion or waterproof paint. This treatment not only affects the gloss and color of the timber surface but can also easily cause harm to the human body. Such anti-corrosion and moisture-proofing measures only target the outer layer of the timber; once the outer paint layer peels off, the protective measures immediately become ineffective. Utility Model Content

[0004] This utility model addresses the technical problem that relying on external coatings for moisture and corrosion protection of timber is ineffective and affects the gloss and color of the timber surface. It provides a moisture and corrosion resistant timber for construction projects, comprising a timber body, which includes a core and a timber kit nested outside the core. The core is a resin-impregnated core, which is impregnated with a preservative. The resin-impregnated core is a straight quadrangular prism and matches the hollow structure of the timber kit.

[0005] The inner wall of the timber kit is uniformly coated with a hydrophobic resin layer, and the outer wall of the timber kit is a boil-modified layer.

[0006] Preferably, in the above technical solution, the cross-section of the timber kit is rectangular and annular, and two rows of storage slots are evenly distributed side by side on the top and bottom surfaces of the timber kit, and one row of storage slots is evenly distributed on the inner side surface of the timber kit.

[0007] Preferably, in the above technical solution, the storage tank is filled with silica gel desiccant.

[0008] Preferably, in the above technical solution, the outer surface of the resin-impregnated core is provided with protrusions corresponding to the storage tank.

[0009] Preferably, in the above technical solution, a groove is provided at the middle position of the top surface and the bottom surface of the resin-impregnated core.

[0010] Preferably, in the above technical solution, the groove extends along the axial direction of the grease-impregnated core, and each end of the groove is provided with an arc-shaped snap-fit ​​groove.

[0011] Preferably, in the above technical solution, the top and bottom surfaces of the timber kit are provided with slides that match the slide groove, and the ends of the slides are provided with arc-shaped snap-fit ​​parts that match the arc-shaped snap-fit ​​groove.

[0012] Preferably, in the above technical solution, the hydrophobic resin layer is an epoxy resin layer.

[0013] Preferably, in the above technical solution, the preservative impregnated in the resin-impregnated core is copper azole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention divides the timber into a core and a timber assembly, and applies different anti-corrosion and moisture-proof treatments to each. The core is impregnated with a liquid preservative to ensure high anti-corrosion performance. The outer layer of the timber assembly is steamed to modify it, denaturing the wood proteins and sealing the microporous structure of the cell walls, thus reducing moisture absorption. A hydrophobic resin layer coated on the inner wall of the timber assembly effectively prevents moisture from entering the timber, improving its moisture-proof performance. The timber can achieve improved anti-corrosion performance from the inside out without relying on external coatings.

[0016] This invention controls and reduces the internal humidity of the wood by uniformly providing multiple storage slots on the top, bottom, and inner sides of the wood kit and filling the slots with silica gel desiccant. This prevents the wood from corroding due to excessive humidity, ensures uniform shrinkage of the wood fibers, reduces deformation and cracking caused by humidity changes, and significantly reduces damage to the wood caused by wood-boring insects.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-5As shown, this utility model discloses a type of anti-corrosion and moisture-proof timber for construction projects, comprising a timber body 1, which includes a core 2 and a timber assembly 3 nested outside the core 2. The core 2 is a resin-impregnated core 4, impregnated with a preservative. The preservative impregnated in the resin-impregnated core 4 is copper azole. After impregnation, the copper azole fills the cell cavities and pits of the core 2, blocking moisture transport channels. If pressure treatment is applied during this process, the copper azole can penetrate deep into the wood, forming a good moisture barrier. The resin-impregnated core 4 is a straight quadrangular prism, matching the hollow structure of the timber assembly 3. The inner wall of the timber assembly 3 is uniformly coated with a hydrophobic resin layer 312, and the outer wall of the timber assembly 3 is a boil-modified layer 313. Boiling and heating the timber assembly 3 denatures the wood proteins, sealing the microporous structure on the cell walls to reduce moisture absorption capacity, thereby improving the moisture-proof performance of the timber assembly 3. The hydrophobic resin layer 312 is an epoxy resin layer. The epoxy resin forms a continuous film on the wood surface, covering the open-pore structure, preventing moisture from directly contacting the wood fibers, and improving the water-blocking performance from the inside of the wood frame 3 to prevent it from getting damp and corroded.

[0026] In this embodiment, the cross-section of the timber kit 3 is rectangular and annular. Two rows of storage slots 314 are evenly distributed side-by-side on the top surface 31 and bottom surface 32 of the timber kit 3, and one row of storage slots 314 is evenly distributed on the inner side surface 33 of the timber kit 3. The storage slots 314 are filled with silica gel desiccant 315. The outer surface of the resin-impregnated core 4 has protrusions 212 corresponding to the storage slots 314. The protrusions 212 effectively prevent the silica gel desiccant 315 in the storage slots 314 from shaking and falling out when the timber is moved. The storage tank 314 is positioned between the timber kit 3 and the resin-impregnated core 4. The silica gel desiccant 315 filled in the storage tank 314 can control and maintain the timber kit 3 and the resin-impregnated core 4 in a relatively low humidity environment, so that the internal fibers of the wood shrink evenly, reduce deformation and cracking caused by humidity changes, reduce the hydrophilicity of the wood cell walls, prevent bacteria from multiplying, and significantly reduce the risk of corrosion.

[0027] It should be further explained that the top surface 21 and bottom surface 22 of the resin-impregnated core 4 are both provided with a sliding groove 211 at their midpoints. The sliding groove 211 extends along the axial direction of the resin-impregnated core 4, and its end is provided with an arc-shaped locking groove 213. The inner top surface 31 and inner bottom surface 32 of the timber assembly 3 are provided with sliding strips 316 that match the sliding grooves 211, and their ends are provided with arc-shaped locking elements 317 that match the arc-shaped locking grooves 213. The sliding grooves 211 and sliding strips 316 cooperate with each other to allow the resin-impregnated core 4 to slide within the timber assembly 3. Finally, the arc-shaped locking grooves 213 and arc-shaped locking elements 317 are tightly joined together, making the timber assembly 3 and the resin-impregnated core 4 a single unit, thus improving the overall structural performance of the timber.

[0028] This invention divides the timber into a core and a timber assembly, and applies different anti-corrosion and moisture-proof treatments to each. The core is impregnated with a liquid preservative to ensure high anti-corrosion performance. The outer layer of the timber assembly is steamed to modify it, denaturing the wood proteins and sealing the micropores in the cell walls, reducing moisture absorption. A hydrophobic resin layer coated on the inner wall of the timber assembly effectively prevents moisture from entering the timber, improving its moisture-proof performance. Multiple storage compartments are evenly distributed on the top, bottom, and inner sides of the timber assembly, filled with silica gel desiccant to control and reduce internal humidity, preventing excessive moisture and corrosion. This ensures uniform shrinkage of the wood fibers, reducing deformation and cracking caused by humidity changes and significantly minimizing damage from wood-boring insects. This invention achieves improved moisture-proof and anti-corrosion performance from the inside out without relying solely on external coatings, thus enhancing the overall quality of the timber.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
