Description

Technical Field

[0001] This utility model relates to a building template, and more particularly to a plastic building template. Background Technology

[0002] In the construction industry, plywood plays a crucial role in providing a temporary "mold" for concrete, ensuring it achieves the designed shape and dimensions after solidification. Current plywood is made by bonding and pressing multiple layers of veneer (or thin wood sheets) together with adhesives. Most plywood relies on synthetic adhesives such as urea-formaldehyde resin and phenolic resin. Some low-priced products use substandard adhesives, potentially releasing formaldehyde and other harmful substances during production or use, posing a risk of indoor air pollution. Furthermore, the wood utilization rate during rotary cutting and slicing to obtain veneers is only about 60%–70%, generating large amounts of wood dust, wood chips, and other waste. Additionally, waste plywood is difficult to recycle and reuse due to the difficulty in separating the adhesives, easily leading to resource waste. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model proposes a plastic building template.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a plastic building template, including a core board, a single-layer board and a plastic board; The core board is thicker than 10mm, and the top and bottom ends of the core board are respectively provided with single-plate portions, each of which is provided with a plastic plate. The core board and the single-board portion are connected by adhesive, and the single-board portion and the plastic board are also connected by adhesive; The single-board section includes at least two single-board units, and a reinforcing mesh is provided between adjacent single-board units. The single-board units and the reinforcing mesh are connected by adhesive.

[0005] In a preferred embodiment of this utility model, the plastic sheet is made of PP or PE material.

[0006] In a preferred embodiment of this utility model, the reinforcing mesh is made of polyester.

[0007] In a preferred embodiment of this utility model, the core board is a plywood board made of multiple solid wood strips spliced ​​together.

[0008] In a preferred embodiment of this utility model, the wood fibers of the veneer unit connected to the core board are perpendicular to the splice seams of the multiple solid wood strips.

[0009] The beneficial effects of this utility model are: by replacing at least three layers of veneer with plywood, the number of veneers in the building formwork is reduced, thereby reducing the use of adhesives, reducing environmental pollution, saving resources, and lowering costs. Simultaneously, it helps improve the production efficiency of plastic building formwork. In this application, at least two layers of veneer units are respectively set at the top and bottom of the plywood, with a reinforcing mesh between the two layers of veneer. The reinforcing mesh increases the connection strength between the two veneer units, thereby improving the overall structural strength of the building formwork. At the same time, the wood fibers of the veneer units connected to the core board are perpendicular to the splicing seams of multiple solid wood strips, which allows the plywood to have good strength and stability in both the horizontal and vertical directions, effectively avoiding deformation and cracking problems caused by stress during use, and helping to extend the service life of the plastic building formwork.

They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] like Figure 1 A plastic building template is shown, comprising a core board 1, a single-layer board 2, and a plastic board 3; The core board 1 has a thickness greater than 10mm. The core board 1 has a single board portion 2 at its top and bottom, and a plastic board 3 is provided on each of the single board portions 2. The core board 1 and the single board part 2 are connected by adhesive, and the single board part 2 and the plastic board 3 are also connected by adhesive; The single-layer panel 2 includes at least two single-layer panel units 201, and a reinforcing mesh 4 is provided between adjacent single-layer panel units 201. The single-layer panel units 201 and the reinforcing mesh 4 are connected by adhesive. The reinforcing mesh 4 in this application is made of polyester.

[0015] In a preferred embodiment, the core board 1 is a plywood made of multiple solid wood strips spliced ​​together. Furthermore, the wood fibers of the veneer unit 201 connected to the core board 1 are perpendicular to the joints of the multiple solid wood strips.

[0016] In this embodiment of the application, the single-layer section 2 of the plastic building template consists of two single-layer units 201. The plastic building template, from top to bottom, consists of a plastic board 3, a single-layer unit 201, a polyester reinforcing mesh 4, a single-layer unit 201, a plywood, a single-layer unit 201, a polyester reinforcing mesh 4, a single-layer unit 201, and a plastic board 3. In this application, the thickness of the plywood is 11-15mm, and the thickness of the single-layer unit is 2-5mm.

[0017] Existing plywood typically consists of three or more layers of veneer, usually an odd number of layers, though an even number is possible in special cases. Common types include three, five, seven, nine, and thirteen layers. The thickness of each veneer layer is typically between 0.2 mm and 5 mm. In this application, by using blockboard with a thickness greater than 10 mm, the blockboard can replace at least three layers of veneer, reducing the number of veneers in the formwork, thereby reducing adhesive usage, environmental pollution, resource conservation, and cost reduction. Simultaneously, while reducing the number of veneers, using thicker blockboard to replace multiple layers of veneer improves the production efficiency of plastic formwork. As a preferred embodiment, the plastic plate 3 at the top of the veneer section is made of PP or PE material. The plastic plate helps increase the structural strength of the formwork, extends its service life, and facilitates demolding. In this application, at least two layers of veneer units are respectively set at the top and bottom of the plywood, and a reinforcing mesh is set between the two layers of veneer units. The reinforcing mesh increases the connection strength between the two veneer units, thereby improving the overall structural strength of the building formwork. At the same time, the wood fibers of the veneer unit 201 connected to the core board 1 are perpendicular to the splice seam of multiple solid wood strips. For example, if the splice direction of multiple solid wood strips of the plywood is longitudinal, then the fiber direction of the veneer unit is transverse. This structural design can give the plywood good strength and stability in both the transverse and longitudinal directions, effectively avoiding problems such as deformation and cracking of the board due to stress during use, and helping to extend the service life of the plastic building formwork.
