Description

Technical Field

[0001] The invention relates to the technical field of building materials, in particular to a building template. Background Art

[0002] Building formwork is a temporary support structure, which is made according to the design requirements to shape the concrete structure and components according to the specified position and geometric size, maintain its correct position, and bear the self-weight of the building formwork and the external load acting on it. The purpose of formwork engineering is to ensure the quality and construction safety of concrete engineering, speed up the construction progress and reduce engineering costs.

[0003] The building formwork in the prior art includes wooden building boards and metal building formwork. The wooden building formwork has a low density, which is conducive to reducing the self-weight of the supporting structure, thereby reducing the deformation of the supporting structure. However, the wooden building formwork has a low hardness, poor wear resistance and fire resistance, which not only reduces the number of reuses of the wooden building formwork, but also reduces the fire resistance of the supporting structure. Metal building formwork has strong hardness and good wear resistance and fire resistance, but it has a high density and high manufacturing cost.

[0004] Therefore, there is an urgent need to provide a building template with low density and good wear resistance and fire resistance. Summary of the invention

[0005] One of the purposes of the present invention is to provide a building template that solves the technical problem of poor wear resistance and fire resistance of building templates in the prior art. The preferred embodiment of the present invention can achieve many beneficial effects, as described below.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A building template comprises a wear-resistant layer and a base layer, wherein the wear-resistant layer is located on the upper and lower surfaces of the base layer, the wear-resistant layer comprises a wear-resistant surface and a reinforcement surface, the reinforcement surface comprises a meridian layer, and the meridian layer is located on a side of the wear-resistant layer close to the base layer, and the wear-resistant surface is located on a side of the wear-resistant layer far from the base layer.

[0008] Furthermore, the meridian layer is adhered and / or embedded on a side of the wear-resistant layer close to the base layer.

[0009] Furthermore, the meridian layer includes meridian lines, and the meridian lines have at least two or more different directions.

[0010] Furthermore, the meridian layer is a fiber cloth.

[0011] Furthermore, the meridian thread contains carbon fiber and / or glass fiber.

[0012] Furthermore, the wear-resistant surface is a smooth surface plane, so as to form a smooth wall surface through casting of building formwork.

[0013] Furthermore, the wear-resistant layer includes mineral powder and sawdust, and the mineral powder and sawdust are embedded in the wear-resistant layer to enhance the wear resistance of the wear-resistant layer.

[0014] Furthermore, the wear-resistant layer is bonded and / or laminated to the base layer as a whole.

[0015] Furthermore, the base layer includes wooden boards and / or bamboo strips, and the wooden boards and / or bamboo strips are bonded together.

[0016] Furthermore, the thickness of the base layer is 5 mm to 30 mm.

[0017] The building template provided by the present invention has at least the following beneficial technical effects:

[0018] The building formwork described in the present invention includes a base layer and a wear-resistant layer, wherein the base layer is located between the wear-resistant layers, so that the wear-resistant layer can protect the base layer, which not only avoids the base layer from contacting, rubbing and / or scraping with the outside world during use, but also can use the wear-resistant layer to isolate external heat sources, prevent the base layer from direct contact with the fire source, and improve the fire resistance of the building formwork, thereby achieving the purpose of protecting the base layer and extending the service life of the building formwork, and realizing long-term repeated use of the building formwork.

[0019] The wear-resistant layer includes a wear-resistant surface and a reinforcement surface, and the reinforcement surface includes a meridian layer. The meridian layer can effectively improve the toughness of the wear-resistant layer and prevent the wear-resistant layer from breaking and / or falling off. The meridian layer is located on the side of the wear-resistant layer close to the base layer. On the one hand, it can enhance the toughness of the wear-resistant layer, and on the other hand, it can make the toughness between the wear-resistant layer and the base layer form a transition through the meridian layer, thereby preventing stratification between the wear-resistant layer and the base layer. The wear-resistant surface is located on the side of the wear-resistant layer away from the base layer, which can not only increase the amount of wear on the surface of the building formwork, but also protect the meridian layer, prevent the meridian layer from being worn during use, and avoid the toughness of the building formwork from being reduced due to wear.

[0020] In addition, the preferred technical solution of the present invention can also produce the following technical effects:

[0021] The meridian layer of the preferred technical solution of the present invention comprises two or more meridian lines, so that the toughness of the wear-resistant layer in all directions is balanced;

[0022] The meridian lines of the preferred technical solution of the present invention contain carbon fiber and / or glass fiber. The strong tensile strength of carbon fiber and / or glass fiber is used to enhance the toughness of the wear-resistant layer and prevent the wear-resistant layer from cracking. In addition, both glass fiber and carbon fiber have good heat resistance, so that the physical properties of the wear-resistant layer will not decrease significantly due to changes in external temperature, thereby improving the fire resistance of the building formwork.

[0023] The wear-resistant surface of the preferred technical solution of the present invention is a smooth plane, which can effectively improve the flatness of the wall surface, thereby reducing the secondary decoration of the wall surface.

[0024] The base layer of the preferred technical solution of the present invention comprises wooden boards and / or bamboo strips. Both the wooden boards and bamboo strips have strong tensile strength and bending resistance, and the density of the wooden boards and bamboo strips is relatively small, which can effectively reduce the density of the building formwork and further improve the portability of the building formwork.

[0025] The building template of the preferred technical solution of the present invention has a base layer of wood boards and / or bamboo strips, and a wear-resistant layer including a reinforcement surface so that the building template can be made into various shapes required for construction and repair through processing techniques such as sawing, planing, and nailing.

[0027] The building formwork of the preferred technical solution of the present invention can be completely recycled after use, for example, it can be recycled and used as a filling spacer for non-load-bearing wall cavities. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0038] The "upper and lower surfaces of the base layer" described in the present specification refers to the upper and lower surfaces of the building template such as the attached Figure 1 To Attachment Figure 7 The upper and lower surfaces of the flat base layer are shown.

[0039] Example 1

[0040] Reference Figure 1 A building formwork comprises a wear-resistant layer 1 and a base layer 2, wherein the wear-resistant layer 1 is located on the upper and lower surfaces of the base layer 2, the wear-resistant layer 1 comprises a wear-resistant surface and a reinforcement surface, the reinforcement surface comprises a meridian layer 11, and the meridian layer 11 is located on a side of the wear-resistant layer 1 close to the base layer 2, and the wear-resistant surface is located on a side of the wear-resistant layer 1 far from the base layer 2.

[0041] Reference Figure 1 or Figure 2 The meridian layer 11 is pasted and / or embedded on the side of the wear-resistant layer 1 close to the base layer 2.

[0042] Preferably, the meridian layer 11 is embedded in the wear-resistant layer 1 on the side close to the base layer 2. Figure 2 The meridian layer 11 is embedded in the wear-resistant layer 1. On the one hand, the meridian layer 11 can be completely dissolved with the wear-resistant layer 1 to avoid stratification between the meridian layer 11 and the wear-resistant layer 1. On the other hand, embedding the meridian layer 11 in the wear-resistant layer 1 can effectively increase the contact area between the meridian layer 11 and the wear-resistant layer 1, thereby increasing the friction between the meridian layer 11 and the wear-resistant layer 1.

[0043] It should be noted that the meridian layer 11 is added to the wear-resistant layer 1 mainly to utilize the meridian layer 11 to improve the tensile strength of the building formwork.

[0044] Specifically, when the building template is subjected to external tension, it mainly acts on the wear-resistant layer 1 located on the surface layer, and then is transmitted to the meridian layer 11 and the base layer 2 through the wear-resistant layer 1, so that the building template as a whole is subjected to tension. The transmission of tension inside the building template is mainly achieved through the bonding force and / or friction force between the wear-resistant layer 1 and the meridian layer 11, and between the wear-resistant layer 1 and the base layer 2.

[0045] When the adhesive force and / or friction force between the wear-resistant layer 1 and the meridian layer 11 and between the wear-resistant layer 1 and the base layer 2 is greater, the pulling force can be more effectively distributed to each part of each layer of the building template, so that the deformation of each part in the building template is consistent, and the purpose of overall force balance of the building template is achieved, thereby maximizing the transfer of pulling force to the meridian layer 11 with good tensile strength. Therefore, the meridian layer 11 embedded in the wear-resistant layer 1 can effectively improve the tensile and compressive resistance of the building template.

[0046] As an implementable alternative, the wear-resistant layer 1 includes two meridian layers 11 , one layer is located on the wear-resistant surface, and the other layer is located on the reinforcement surface, and the meridian layers 11 are embedded in the wear-resistant layer 1 .

[0047] Reference Figure 2 The meridian layer 11 includes meridian lines 111, and the meridian lines 111 include at least two or more meridian lines 111 in different directions. Preferably, the meridian layer 11 includes two meridian lines 111 in mutually perpendicular directions.

[0048] As a preferred embodiment of the present invention, the meridian line 111 includes carbon fiber and / or glass fiber. Preferably, the meridian layer 11 is a fiber cloth.

[0049] As a preferred embodiment of the present invention, the fiber cloth in the meridian layer 11 is a mesh structure, so that the meridian layer 11 can be better embedded in the wear-resistant layer 1, so that the wear-resistant layer 1 and the meridian layer 11 are better fused into a whole.

[0050] As a preferred embodiment of the present invention, the wear-resistant surface is a smooth surface plane, so that a smooth wall surface can be formed by casting the building formwork.

[0051] It should be noted that the building template is mainly used for concrete molding. The flatness of the surface of the building template is consistent with the surface flatness of the wall and / or column to which it corresponds. The smoother and flatter the surface of the building template, the smoother and flatter the surface of the wall and / or column formed by the template. Therefore, setting the wear-resistant surface as a smooth surface can reduce the need for re-leveling of the wall and / or column, thereby reducing secondary decoration.

[0052] As a preferred embodiment of the present invention, the wear-resistant layer 1 includes mineral powder and sawdust, and the mineral powder and sawdust are embedded in the wear-resistant layer 1 to enhance the wear resistance of the wear-resistant layer 1 and reduce the density of the building formwork.

[0053] It should be noted that the mineral powder, sawdust and reinforcing agent form a mixed slurry under the action of water. The water in the mixed slurry evaporates and condenses into blocks, so that the mineral powder and sawdust are embedded in the wear-resistant layer 1. The mineral powder, sawdust and reinforcing agent can form a solid layer with high strength and high hardness, which can greatly improve the wear resistance of the building formwork. In addition, the wear-resistant layer formed by the mineral powder, sawdust and reinforcing agent will not burn, so it has excellent fire resistance and fireproof performance. Specifically, the wear-resistant layer 1 enables the fire protection level of the building formwork to reach Class A and above.

[0054] The wear-resistant surface of the preferred technical solution of the present invention includes mineral powder, sawdust and a reinforcing agent. The mineral powder can effectively improve the hardness and strength of the building template and improve the wear resistance of the building template. Sawdust has better toughness than mineral powder. On the one hand, it can effectively increase the compactness between the components of the wear-resistant layer 1, that is, make the components more closely combined, and on the other hand, it can improve the toughness of the wear-resistant layer 1. The light weight of sawdust can reduce the density of the building template, thereby making the building template lighter.

[0055] It should be noted that sawdust has better softness than mineral powder. By mixing sawdust and mineral powder, sawdust is mixed between mineral powders. The relatively softness of sawdust enables the sawdust to make adaptive deformation when squeezed. The adaptive deformation of sawdust is fixed by drying with the reinforcing agent, so that the sawdust can improve the compactness between the mineral powder and / or the reinforcing agent in the wear-resistant layer 1 material, improve the hardness and compressive strength of the wear-resistant layer 1, and thus achieve the purpose of improving the wear resistance of the building formwork.

[0056] On the other hand, when the building formwork is squeezed and / or bent, the mineral powder and / or reinforcing agent in the wear-resistant layer 1 will squeeze and / or stretch the sawdust in the wear-resistant layer 1, causing the sawdust to deform adaptively, thereby achieving corresponding compression and / or stretching of the wear-resistant layer 1, thereby alleviating and / or dispersing the tension and / or pressure on the building formwork.

[0057] As an practicable alternative of the present invention, the mineral powder may be perlite or fly ash. The sawdust may be powder formed by crushing plant bodies, such as wood powder or straw powder.

[0058] As a preferred embodiment of the present invention, the ratio of mineral powder, sawdust and strengthener is 1:3:2.

[0059] As a preferred embodiment, the wear-resistant layer 1 also contains an insect repellent. Preferably, the insect repellent is located on the reinforcement surface to prevent the meridian layer 11 and / or the base layer 2 from being eaten by insects.

[0060] As a preferred embodiment of the present invention, the strengthening agent includes magnesium oxide and magnesium chloride, and the mixing ratio of magnesium oxide and magnesium chloride is 1: 1. Preferably, the magnesium oxide can be light-burned magnesium oxide.

[0061] Specifically, light-burned magnesium oxide and magnesium chloride aqueous solution are matched in a certain proportion to gel and harden into a hardened body with high strength and good fireproof and heat insulation. Preferably, a certain proportion of mineral powder and sawdust are mixed in the light-burned magnesium oxide, and the mineral powder and sawdust are evenly distributed in the light-burned magnesium oxide and magnesium chloride aqueous solution through sufficient stirring and mixing, so that the mineral powder and sawdust are evenly distributed in the hardened material formed by the light-burned magnesium oxide and magnesium chloride, that is, the mineral powder and sawdust are evenly distributed in the wear-resistant layer 1.

[0062] Mineral powder particles have the characteristic of high hardness, so the mineral powder evenly distributed in the wear-resistant layer 1 can effectively improve the wear resistance of the wear-resistant layer 1. Sawdust has a small density and a relatively loose material, so the sawdust distributed in the wear-resistant layer 1 can effectively reduce the density of the wear-resistant layer 1, thereby reducing the weight of the wear-resistant layer 1 per unit volume, making the building formwork lighter. Adding mineral powder and sawdust to the wear-resistant layer 1 can also effectively improve the toughness of the wear-resistant layer 1, making the wear-resistant layer 1 have better toughness and expanding the deformation range of the wear-resistant layer 1.

[0063] As a preferred embodiment of the present invention, the thickness of the wear-resistant layer 1 is 2 mm to 10 mm.

[0064] As a preferred embodiment of the present invention, the wear-resistant layer 1 is bonded and / or adhered to the base layer 2. Preferably, the wear-resistant layer 1 is bonded to the base layer 2 through a slurry prepared from sawdust, mineral powder and a reinforcing agent.

[0065] As a preferred embodiment of the present invention, the base layer 2 includes wooden boards and / or bamboo strips, and the wooden boards and / or bamboo strips are bonded together. The wooden boards and / or bamboo strips can effectively improve the tensile strength and flexural strength of the building formwork.

[0066] Preferably, the base layer 2 may be composed of multiple layers of wood boards and / or multiple layers of bamboo strips, and each layer of wood boards and / or bamboo strips is bonded and adhered by a paste prepared by sawdust, mineral powder and a reinforcing agent. By bonding after preparing sawdust, mineral powder and a reinforcing agent, the building wood boards do not contain harmful additives, thereby improving the air quality and providing a safer and healthier link for the construction site.

[0067] As an practicable alternative of the present invention, the wooden boards and / or bamboo strips may be bonded together by adhesive.

[0068] As an alternative embodiment of the present invention, the base layer 2 may also be straw, such as rice straw, cotton stalks, wheat stalks, corn stalks, etc.

[0069] In a preferred embodiment of the present invention, sawdust can be replaced by plant powder, and the base layer 2 can utilize discarded wood boards, straw, bamboo strips, etc., so that most of the discarded plant bodies, such as discarded furniture, wood boards, and straw in agricultural by-products, can be reused, thereby effectively reducing the amount of tree felling.

[0070] As a preferred embodiment of the present invention, the base layer 2 comprises a wooden board and / or bamboo strips, and the thickness of the base layer is 5 mm to 30 mm. Preferably, the thickness of the base layer 2 can be 5 mm, 7 mm, 9 mm, 10 mm, 15 mm, 20 mm, or 25 mm.

[0071] Preferably, the bamboo strips in the base layer 2 are arranged crosswise, so that the radial and longitudinal tensile strengths of the base layer 2 are balanced.

[0072] As a preferred embodiment of the present invention, the thickness of the building template is 10 mm to 50 mm.

[0073] Example 2

[0074] This embodiment is a further improvement on Embodiment 1, and only the improved part is described in detail below.

[0075] As a preferred embodiment of the present invention, a through hole is provided in the base layer 2, and a reinforcing member 3 matching the through hole is included in the wear-resistant layer 1, and the reinforcing member 3 is embedded in the through hole of the base layer 2. On the one hand, the provision of the reinforcing member 3 can effectively improve the transmission efficiency of the shear stress between the base layer 2 and the wear-resistant layer 1 in the building formwork, and prevent the base layer and the wear-resistant layer 1 from being delaminated. On the other hand, the reinforcing member 3 can effectively improve the compressive strength of the building formwork.

[0076] As a preferred embodiment of the present invention, the reinforcing member 3 is fixedly connected to the friction-resistant layer 1. Preferably, the wear-resistant layer 1 and the reinforcing member 3 are designed as one body. Specifically, a through hole is reserved in the base layer 2, and then a mixture of sawdust, mineral powder, and a reinforcing agent for forming the wear-resistant layer 1 is injected into the through hole, thereby gelling to form the reinforcing member 3.

[0077] Reference Figure 3 or Figure 4 When the friction-resistant layer 1 is subjected to external tension, the tension will be dispersed to the base layer 2 through the bonding force between the wear-resistant layer 1 and the base layer and the force between the reinforcement 3 and the base layer 2.

[0078] As a preferred embodiment of the present invention, a through hole is set in the base layer 2, and the reinforcement 3 in the wear-resistant layer 1 passes through the through hole, so that the wear-resistant layer 1 located on both sides of the base layer 2 can be connected through the reinforcement 3, thereby further strengthening the adhesion between the base layer 2 and the wear-resistant layer 1, and can enhance the compressive resistance of the building formwork.

[0079] Specifically, when the building formwork is subjected to pressure, the strong hardness of the reinforcement member 3 can disperse the external pressure acting on the building formwork, thereby reducing the pressure on the base layer 2. Therefore, the reinforcement member 3 can effectively reduce the pressure on the base layer 2, so that the base layer 2 is better protected.

[0080] Example 3

[0081] This embodiment is a further improvement of Embodiment 1 and Embodiment 2, and only the improved parts are described in detail below.

[0082] Reference Figure 5 or Figure 6 as well as Figure 7 The building template also includes a fixing member 4 for convenient connection and fixing with the outside world.

[0083] Specifically, the building template includes a through hole and a fixing member 4 matching the through hole, and the fixing member 4 is embedded in the through hole so that the through hole in the building template is completely filled. Preferably, the fixing member 4 is a plastic material so that nails and / or bolts used to fix the building template can pass through the fixing member 4.

[0084] The provision of the fixing member 4 can not only effectively reduce the difficulty of drilling holes in the building template during the fixing process, but also improve the stability of the connection used for fixing with the outside world, and prevent the building template from breaking at the nailing and / or installation bolts during molding, thereby improving the stability of the building template molding and ensuring the molding accuracy.

[0085] As a preferred embodiment of the present invention, the fixing member 4 can be a solid wooden stick or plastic.

[0086] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
