Description

Technical Field

[0001] This utility model relates to the field of building timber formwork technology, specifically a building timber formwork resistant to high temperature and high pressure. Background Technology

[0002] When constructing a building, it is necessary to pour concrete for beams, shear walls, and other structural elements. Formwork is indispensable for the pouring of beams and shear walls. The formwork supports the poured concrete through its erection and assembly, allowing it to gradually solidify and dry, resulting in sturdy shear walls or beams. As a crucial tool for concrete forming, the quality of the formwork directly affects the project's quality and progress. Traditional wooden formwork typically involves cutting and assembling templates to form wall panels, using timber as secondary supports. However, under high temperature and pressure during construction, the formwork is prone to deformation and cracking, affecting its lifespan and the final shape of the dried concrete. Utility Model Content

[0003] The purpose of this utility model is to provide a high-temperature and high-pressure resistant wooden formwork for construction, so as to solve the problem mentioned in the background art that wooden formwork is prone to deformation and cracking when faced with high temperature and high pressure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a high-temperature and high-pressure resistant building wooden formwork, comprising high-quality boards, wherein vertical core layers are uniformly pasted and fixed on the outer surface of the high-quality boards, and the vertical core layers are spaced apart from each other; a metal frame is snapped onto the outer surface of the high-quality boards, and the outer surface of the metal frame is tightly fitted to the outer surface of the high-quality boards; a core layer structure is provided between the outer surface of the high-quality boards and the metal frame, and the core layer structure disperses the external force generated during pouring to improve the overall compressive strength and deformation resistance of the formwork.

[0005] Preferably, the core layer structure includes: a transverse core layer, which is uniformly pasted and fixed on the outer surface of the vertical core layer, with uniform gaps between the transverse core layers, and another high-quality board is pasted and fixed on the outer surface of the end of the transverse core layer away from the vertical core layer.

[0006] By adopting the above technical solution, the compressive strength of the entire formwork is enhanced by bonding the vertical and horizontal core layers between the high-quality boards. This allows the high-quality boards, vertical core layers, and horizontal core layers to effectively disperse external forces after concrete pouring. At the same time, the gaps left between the vertical and horizontal core layers reduce the effects of expansion and contraction caused by humidity and temperature, and provide a certain displacement space under stress. This avoids deformation and cracking caused by mutual compression between the vertical and horizontal core layers, thereby improving the compressive strength and deformation resistance of the formwork.

[0007] Preferably, the outer surface of the high-quality board is impregnated with multiple layers of phenolic resin, and the side surface of the phenolic resin is tightly bonded to the outer surface of the metal frame. The high-quality board is subjected to high-temperature drying treatment.

[0008] By adopting the above technical solution, after high-temperature drying, the high-quality board can remove the moisture and impurities inside the board, improving its stability. At the same time, the outer surface of the board is impregnated with multiple layers of phenolic resin, forming a dense protective film. This not only enhances the wear resistance and corrosion resistance of the board, but also gives it good high-temperature resistance, reduces the chance of the board deforming when wet, and improves its wear resistance and high-temperature resistance, making the template more durable.

[0009] Preferably, the outer surfaces of the high-quality sheet material, the vertical core layer, and the horizontal core layer are engaged with the outer surface of the metal frame, and screws are installed through the outer surface of the metal frame, with the screws threadedly connected to the vertical core layer and the horizontal core layer. The side surface of the metal frame is provided with a snap-fit ​​mechanism, which allows the templates to be connected to each other.

[0010] By adopting the above technical solution, the metal frame can be connected and fixed to the high-quality board, the vertical core layer and the horizontal core layer by screws, so that the metal frame can be stably connected and fixed to the high-quality board, the vertical core layer and the horizontal core layer.

[0011] Preferably, the snap-fit ​​mechanism includes: a snap-fit ​​block, the snap-fit ​​block being formed on one side surface of the metal frame, and a groove being formed on the outer surface of the metal frame away from the snap-fit ​​block, a fastening strip being fixedly formed on one side surface of the metal frame, and a locking strip being fixedly formed on the side surface of the metal frame away from the fastening strip, and the locking strip engaging with a fastening strip on the side surface of the other metal frame.

[0012] By adopting the above technical solution, the metal frames can be interlocked and positioned by pressing the snap-fit ​​blocks and grooves together, and by snapping the strips and clips together. This allows the templates to be connected and positioned together, and can eliminate the gaps between the metal frames, reducing the chance of concrete leaking out of the templates after pouring.

[0013] Preferably, a transverse reinforcing rib is fixedly installed on the outer surface of one end of the metal frame, and a longitudinal reinforcing rib is fixedly installed on the outer surface of the transverse reinforcing rib. Both ends of the longitudinal reinforcing rib are fixed to the outer surface of the metal frame. The outer surface of the longitudinal reinforcing rib is bonded to the outer surface of the phenolic resin, and the outer surface of the phenolic resin is bonded to the outer surface of the transverse reinforcing rib. An interlocking connection structure is provided between the transverse reinforcing rib and the longitudinal reinforcing rib. The interlocking connection structure strengthens the connection strength between the metal frames and improves the connection strength between the fasteners, clips, and clip blocks.

[0014] By adopting the above technical solution, the horizontal and vertical reinforcing ribs can enhance the deformation resistance and compressive strength of the high-quality sheet material, vertical core layer, and horizontal core layer, and can confine the high-quality sheet material, vertical core layer, and horizontal core layer inside the metal frame.

[0015] Preferably, the plug-in connection structure includes: a snap-fit ​​connector, which is fixedly installed on the outer surfaces of both ends of the transverse reinforcing rib and the longitudinal reinforcing rib, and a plug is fixedly installed on the end of the transverse reinforcing rib away from the snap-fit ​​connector. The plug at one end of the transverse reinforcing rib is close to the snap-fit ​​block, and the snap-fit ​​connector at one end of the longitudinal reinforcing rib is close to the snap-fit ​​strip. The snap-fit ​​connector and the plug are plugged into each other, and bolts are respectively installed through the outer surfaces of the snap-fit ​​connector and the plug, and the outer surfaces of the bolts are respectively in contact with the outer surfaces of the snap-fit ​​connector and the plug.

[0016] Using the above technical solution, when the metal frame is connected by the snap-fit ​​blocks, fasteners and clips, the snap-fit ​​connectors and plugs will be plugged into each other. At this time, the snap-fit ​​connectors and plugs can be connected together by inserting bolts to strengthen the connection strength between the snap-fit ​​blocks, fasteners and clips and fix them, so as to facilitate the quick connection and assembly of the metal frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the high temperature and high pressure resistant construction wood formwork: 1. The vertical core layer between high-quality boards enhances the longitudinal compressive strength of the template, while the transverse core layer between high-quality boards enhances the transverse compressive strength of the template. At the same time, the gap between the vertical and transverse core layers prevents the wood from expanding and contracting due to environmental humidity and temperature. Furthermore, when the high-quality boards, vertical core layers, and transverse core layers are deformed by external forces, the reserved gaps can also deform and adjust freely to a certain extent, allowing the template to have good resistance to deformation and compressive strength when used in high-temperature and high-pressure environments. 2. By high-temperature drying of high-quality boards, the moisture and impurities inside the boards can be removed, improving the stability of the wood. At the same time, when the high-quality boards are immersed in phenolic resin for impregnation, the phenolic resin will adhere to the outer surface of the boards and form a protective layer after the phenolic resin dries. This not only enhances the wear resistance and corrosion resistance of the high-quality boards, but also gives them good high-temperature resistance, allowing the boards to maintain stable physical and chemical properties at high temperatures and preventing deformation caused by moisture penetration, thereby extending the service life of the formwork. 3. By fixing the metal frame to the side surfaces of the high-quality board, vertical core layer and horizontal core layer with screws, the template will not have the chance of edge damage and deformation during use, and can further enhance the overall strength and stability of the template. At the same time, the setting of horizontal and vertical reinforcing ribs allows the template to withstand greater pressure and impact, making the template more durable and extending its service life. 4. The metal frame can be spliced ​​and positioned by means of snap-fit ​​blocks, fasteners and clips. During the splicing and positioning process, the snap-fit ​​connectors and plug connectors will be plugged together. At this time, bolts can be inserted to fix the snap-fit ​​connectors and plug connectors, so that the template can be quickly positioned and snapped together and can be fixed together, thereby improving the splicing speed of the template and improving the efficiency of construction and pouring.

[0020] 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.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a high-temperature and high-pressure resistant building wood formwork, including a high-quality board 1, with vertical core layers 2 uniformly pasted and fixed on the outer surface of the high-quality board 1, and the vertical core layers 2 are spaced apart from each other. A metal frame 5 is snapped onto the outer surface of the high-quality board 1, and the outer surface of the metal frame 5 is tightly attached to the outer surface of the high-quality board 1. A core layer structure is provided between the outer surface of the high-quality board 1 and the metal frame 5. The core layer structure disperses the external force generated during pouring to improve the overall compressive strength and deformation resistance of the formwork.

[0022] By tightly bonding the metal frame 5 with the high-quality board 1, the vertical core layer 2, and the horizontal core layer 3, the leakage of concrete from the gaps between the metal frame 5 and the high-quality board 1, the vertical core layer 2, and the horizontal core layer 3 can be reduced. After the template is assembled, a release agent is sprayed on the side to be poured to facilitate demolding after the concrete dries.

[0023] The core structure includes: a transverse core layer 3, which is uniformly pasted and fixed on the outer surface of the vertical core layer 2. There are uniform gaps between the transverse core layers 3, and another high-quality board 1 is pasted and fixed on the outer surface of the end of the transverse core layer 3 away from the vertical core layer 2.

[0024] The vertical core layer 2 enhances the longitudinal compressive strength of the template, while the horizontal core layer 3 enhances its lateral compressive strength. The gap between the vertical core layer 2 and the horizontal core layer 3 allows for faster drying of the applied adhesive. Furthermore, it effectively disperses stress when the template undergoes slight deformation, allowing the vertical core layer 2 and the horizontal core layer 3 to deform and adjust freely. This also prevents the wood from expanding and contracting due to environmental humidity and temperature, reducing cracking and deformation caused by stress concentration, and lowering the likelihood of template deformation during concrete pouring. Ultimately, this results in better resistance to deformation and compressive strength when the template is used under high temperature and pressure.

[0025] The outer surface of the high-quality board 1 is impregnated with multiple layers of phenolic resin 4, and the side surface of the phenolic resin 4 is tightly bonded to the outer surface of the metal frame 5. The high-quality board 1 is subjected to high-temperature drying treatment.

[0026] The high-quality board 1 is immersed in phenolic resin 4 for impregnation, allowing the phenolic resin 4 to adhere to the outer surface of the high-quality board 1. After multiple impregnations and drying, the multiple layers of phenolic resin 4 on the outer surface of the high-quality board 1 will form a protective layer, improving the overall wear resistance and corrosion resistance of the template. At the same time, it can also give the high-quality board 1 good high-temperature resistance, allowing the high-quality board 1 to maintain stable physical and chemical properties at high temperatures. It can also effectively prevent water penetration, preventing the high-quality board 1 from deforming, and reducing the difficulty of demolding the high-quality board 1 during demolding.

[0027] The outer surfaces of the high-quality board 1, vertical core layer 2 and horizontal core layer 3 are engaged with the outer surface of the metal frame 5, and screws 10 are installed through the outer surface of the metal frame 5. The screws 10 are threadedly connected to the vertical core layer 2 and the horizontal core layer 3. The side surface of the metal frame 5 is provided with a snap-fit ​​mechanism, which can connect the templates to each other.

[0028] By screwing screws 10 into the interior of the vertical core layer 2 and the horizontal core layer 3, the metal frame 5 inserted into the high-quality board 1, the vertical core layer 2 and the horizontal core layer 3 can be fixed. The metal frame 5 strengthens the high-quality board 1, the vertical core layer 2 and the horizontal core layer 3, further enhancing the strength and stability of the template, allowing the template to withstand greater pressure and impact, preventing damage and deformation of the template's edges and corners during use, and improving the template's durability.

[0029] The snap-fit ​​mechanism includes: a snap-fit ​​block 11, which is formed on one side surface of the metal frame 5, and a groove is formed on the outer surface of the metal frame 5 away from the snap-fit ​​block 11. A fastener strip 12 is fixedly formed on one side surface of the metal frame 5, and a snap-fit ​​strip 13 is fixedly formed on the side surface of the metal frame 5 away from the fastener strip 12. The snap-fit ​​strip 13 engages with the fastener strip 12 on the side surface of the other metal frame 5.

[0030] By engaging the snap-fit ​​block 11 with another metal frame 5, and engaging the snap-fit ​​block 11 with the snap-fit ​​strip 12 on the outer surface of the other metal frame 5, the metal frames 5 can be easily spliced ​​and positioned, allowing the template to be quickly positioned and spliced, thus improving the efficiency of construction and pouring.

[0031] A transverse reinforcing rib 6 is fixedly installed on the outer surface of one end of the metal frame 5, and a longitudinal reinforcing rib 7 is fixedly installed on the outer surface of the transverse reinforcing rib 6. Both ends of the longitudinal reinforcing rib 7 are fixed to the outer surface of the metal frame 5. The outer surface of the longitudinal reinforcing rib 7 is bonded to the outer surface of the phenolic resin 4, and the outer surface of the phenolic resin 4 is bonded to the outer surface of the transverse reinforcing rib 6. A plug-in connection structure is provided between the transverse reinforcing rib 6 and the longitudinal reinforcing rib 7. The plug-in connection structure strengthens the connection strength between the metal frames 5 and improves the connection strength between the buckle strip 12, the clip strip 13 and the snap block 11.

[0032] The overall strength of the metal frame 5 can be enhanced by the horizontal reinforcing ribs 6 and the vertical reinforcing ribs 7. At the same time, the horizontal reinforcing ribs 6 and the vertical reinforcing ribs 7 can block the high-quality board 1, the vertical core layer 2 and the horizontal core layer 3, so that the formwork can have stronger support and compressive strength after the concrete is poured.

[0033] The plug-in connection structure includes: a snap-fit ​​connector 8, which is fixedly installed on the outer surfaces of the two ends of the transverse reinforcing rib 6 and the longitudinal reinforcing rib 7, and a plug-in connector 9 is fixedly installed on the end of the transverse reinforcing rib 6 and the longitudinal reinforcing rib 7 away from the snap-fit ​​connector 8. The plug-in connector 9 at one end of the transverse reinforcing rib 6 is close to the snap-fit ​​block 11, and the snap-fit ​​connector 8 at one end of the longitudinal reinforcing rib 7 is close to the snap-fit ​​strip 13. The snap-fit ​​connector 8 and the plug-in connector 9 are plugged into each other, and bolts 14 are respectively installed through the outer surfaces of the snap-fit ​​connector 8 and the plug-in connector 9, and the outer surfaces of the bolts 14 are respectively in contact with the outer surfaces of the snap-fit ​​connector 8 and the plug-in connector 9.

[0034] When the metal frame 5 is spliced ​​together by the snap-fit ​​block 11, the buckle strip 12 and the snap strip 13, the snap-fit ​​connector 8 and the plug connector 9 will be plugged into each other. At this time, the bolt 14 can be inserted into the snap-fit ​​connector 8 and the plug connector 9 to fix the snap-fit ​​connector 8 and the plug connector 9, so that the metal frame 5 can be connected and fixed for quick installation.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
