Description

Technical Field

[0001] The utility model relates to the field of low-carbon engineering wood, and more specifically, to low-carbon engineering wood using weather resistance enhancement technology. Background Art

[0002] Low-carbon engineered wood is an innovative building material with important environmental significance. Low-carbon engineered wood is usually made by advanced processing and treatment technology of renewable wood resources. It has the following significant advantages: First, during the production process, low-carbon engineered wood has relatively low energy consumption and emits less greenhouse gases, which is in line with the concept of sustainable development and low-carbon environmental protection. Secondly, it has excellent mechanical properties. For example, it has high strength and good stability, can withstand large loads, and is suitable for a variety of building structures and application scenarios. Low-carbon engineered wood can be used to build house frames, bridges, outdoor landscape facilities, etc. Existing engineered wood will be cut into specific sizes for easy transportation and use, which leads to the need to cut and splice it in actual use. When splicing, screws are often used or nails are directly driven into the wood. This splicing method will cause damage to the wood itself, which will not only affect the strength of the wood, but also be inconvenient for recycling the wood, resulting in waste. At the same time, the lightness of the wood itself is limited. After long-term use, it will corrode the wood due to the temperature or humidity in the use environment, which will affect the strength of the engineered wood. Utility Model Content

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.

[0021] Example

[0022] See also Figures 1 - 3 As shown, a low-carbon engineered wood using weathering enhancement technology includes an engineered square wood A1, an engineered square wood B2, a protective plate 4 and a connecting plate 44. The end of the engineered square wood A1 is provided with a docking groove 11, and the end of the engineered square wood B2 is provided with a protrusion 21. The protrusion 21 is adapted to the internal size of the docking groove 11, so that the preliminary installation of the engineered square wood A1 and the engineered square wood B2 can be achieved through the cooperation of the two. The engineering square wood A1 is provided with grooves 12 on both sides of one end close to the docking groove 11, and the end of the groove 12 is open. The end of the groove 12 away from the open end is provided with a card slot 13 inwardly, and the ends of the two sides of the engineered square wood B2 close to the protrusion 21 are screwed. The bolt is installed with a clamping plate 3, which protrudes from the end face of the engineering square timber B2. A clamping head 31 is provided on the side where the bottom ends of the two clamping plates 3 are close to each other. The clamping plate 3 is adapted to the groove 12, and the clamping head 31 is adapted to the clamping groove 13. When the two square timbers are connected, the clamping plate 3 will be squeezed by the groove 12 to cause its end to deviate outward, and it itself will be squeezed and accumulate force. When the clamping plate 3 is installed in place, it returns to its original position so that the clamping head 31 can automatically sink into the clamping groove 13, thereby achieving complete fixation of the engineering square timber A1 and the engineering square timber B2. Conversely, when disassembling, the clamping plate 3 can be flipped outward to make the clamping head 31 disengage from the clamping groove 13, or the mounting bolts of the clamping plate 3 can be directly removed.

[0023] Among them, a protective plate 4 is also installed on the surface of the engineering square timber A1 and the engineering square timber B2. The cross-section of the protective plate 4 is U-shaped. The protective plate 4 is placed on the side of the wood that is most vulnerable to impact to prevent the square timber from being damaged due to impact. The protective plate 4 can be made of sheet metal iron.

[0024] Please refer to Figure 1 and Figure 3As shown in the figure, extension strips 41 are symmetrically arranged backward on both sides of the protective plate 4. The protective plate 4 can freely adjust its position to cover the butt joint of the engineering square timber A1 and the engineering square timber B2, so as to improve stability. On the rear ends of the mutually approaching sides of the two extension strips 41, extrusion conical surfaces 42 are provided. On the outer surface of the clamping plate 3, close to one end of the clamping head 31, an extrusion block 32 is provided. The extrusion conical surface 42 is in contact with the inclined surface of the extrusion block 32. By installing the protective plate 4, the fixing of the clamping plate 3 can be realized, preventing the engineering square timber A1 and the engineering square timber B2 from falling off.

[0025] Among them, docking cylinders 43 are symmetrically arranged on both sides of the protective plate 4. Threaded holes are opened on the rear end surfaces of the docking cylinders 43. The connecting plate 44 is placed on the side of the engineering square timber A1 away from the protective plate 4. Both ends of the connecting plate 44 are penetrated by locking bolts 45. The ends of the locking bolts 45 are screwed into the threaded holes of the docking cylinders 43. By screwing the locking bolts 45, the protective plate 4 can be pulled to realize the effective fixing of the protective plate 4.

[0026] Please refer to Figure 1 As shown in the figure, protective coatings 5 are applied to the outer surfaces of the engineering square timber A1 and the engineering square timber B2. The protective coatings 5 can protect the square timbers and different coatings can be applied according to the use environment. For example, when the engineering wood is placed outdoors, a polyurethane coating can be used, and when placed indoors, a wood wax coating can be used. Among them, the protective coating 5 can also adopt a fluorocarbon coating.

[0027] In this embodiment, a weather resistance enhancement technology is adopted to improve the durability and environmental adaptability of engineering wood. The selection and application of the protective coating 5 are key links, mainly including the following aspects:

[0028] Selection of coating materials: According to different use environments, appropriate coating materials are selected. The fluorocarbon coating has excellent weather resistance and ultraviolet resistance and is suitable for outdoor environments, which can effectively prevent the wood from degrading due to long-term exposure to sunlight and rain. The polyurethane coating provides excellent wear resistance and corrosion resistance and is suitable for the protection requirements under various climate conditions.

[0029] Multi-layer coating process: The protective coating 5 adopts a multi-layer coating process. Each layer of coating is evenly applied and fully dried to ensure the thickness and adhesion of the coating. The design of the multi-layer coating not only improves the protection ability of the wood surface but also enhances its durability and aesthetics.

[0030] Construction precautions: During the construction process, ensure that the coating evenly covers the wood surface to avoid missed coating and uneven thickness. After each layer of coating is dried, surface grinding is carried out to improve the adhesion of the next layer of coating and the durability of the overall coating.

[0031] Working principle: The protective coatings 5 on the outer surfaces of the engineering square timbers A1 and B2 can improve the weather resistance of the wood. At the same time, the front protective plates 4 can effectively protect them. When the engineering square timbers A1 and B2 are butted, first, the bumps 21 at the ends are butted with the docking grooves 11 to achieve preliminary fixation. At this time, the clamping plates 3 will move along the grooves 12 on both sides and cause extrusion on the ends of the clamping plates 3, making the bottom thereof offset outward. When the installation is in place, the clamping heads 31 will enter the inside of the clamping grooves 13, and then complete fixation. Then, the protective plates 4 are installed on the outer surfaces of the engineering square timbers A1 and B2, so that the U-shaped protective plates 4 can closely adhere to their surfaces, and the extension strips 41 are placed outside the clamping plates 3. At this time, tightening is achieved through the screwing of the rear connecting plates 44 and the locking bolts 45. During the tightening process, the extrusion cones 42 will extrude the extrusion blocks 32 to ensure the stability of the clamping plates 3 and prevent the engineering square timbers A1 and B2 from falling off each other.

[0032] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its improved concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
