Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of civil engineering, in particular to a concrete structure formwork for civil engineering. BACKGROUND

[0002] In civil engineering construction, the concrete structure formwork is a key temporary facility to ensure the forming quality, size accuracy and construction efficiency of concrete members. With the continuous improvement of construction efficiency, cost control and engineering quality requirements in the construction industry, especially the wide application of fair-faced concrete technology, higher demands are put forward for the rapid assembly, precise adjustment, high stability and excellent forming effect of the formwork system. The traditional formwork system often shows insufficient in dealing with complex structural changes, improving turnover efficiency and adapting to harsh construction environments, therefore, a new type of concrete structure formwork that can balance efficient assembly, self-adaptive adjustment and long-term durability is urgently needed.

[0003] In the prior art, common concrete structure formworks are mostly loose-packed wooden formworks or combined steel formworks. Such formworks are usually manually connected and fixed by a large number of external fasteners (such as nails, bolts or iron wires), and their size adjustment depends on on-site cutting or adding shims, so the overall integrity and standardization are limited. In terms of surface treatment, ordinary formworks mostly rely on brushing release agents to improve the demolding effect, and the adhesion resistance and wear resistance of the panel material itself are generally insufficient.

[0004] However, the prior art has a significant problem: the assembly and adjustment process of the formwork is complicated and inefficient, and it is difficult to quickly and accurately adapt to changes in the cross-sectional size of the member, and the versatility is poor. This leads to the need for frequent on-site adjustments or custom non-standard formworks in construction, not only increasing labor intensity and time consumption, but also restricting the improvement of construction speed and pushing up the comprehensive cost of the project. SUMMARY

[0005] In view of the deficiencies of the prior art, the present application provides a concrete structure formwork for civil engineering, which solves the problems of long construction period, high comprehensive cost and difficulty in meeting high-standard appearance quality requirements caused by the low assembly efficiency, inflexible size adjustment and poor versatility of existing concrete structure formworks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a concrete structure formwork for civil engineering, comprising a first baffle and a second baffle, wherein a connecting plate is fixedly connected to the opposite sides of the first and second baffles, the connecting plate being slidably connected inside a connecting groove, the connecting grooves being respectively disposed inside a third baffle and a fourth baffle, the third and fourth baffles being connected to the connecting plate by connecting bolts, and a connecting assembly being fixedly connected to the adjacent sides of the four baffles, the connecting assembly being used to achieve a better fair-faced concrete effect; insertion grooves are provided on both sides of the right side of the first baffle, and a recess is provided on the adjacent side of the insertion grooves. The groove has a fixed cylinder fixedly connected to both sides of its interior. A fixed rod is slidably connected inside the fixed cylinder. Sliding blocks are fixedly connected to both sides of the fixed rod. A first spring is sleeved on the outside of the fixed cylinder and the fixed rod. One end of the first spring is fixedly connected to the inside of the insertion groove, and the other end of the first spring is fixedly connected to the side of the support plate closest to it. A support plate is fixedly connected to the side of the fixed rod furthest from it. A T-shaped locking block is fixedly connected to the side of the support plate furthest from it. The T-shaped locking block is slidably connected inside the T-shaped locking groove, which is located inside the insertion block. The insertion block is fixedly connected to both sides of the left side of the second baffle.

[0007] Preferably, the connecting assembly includes a support plate, which is fixedly connected to one of the four baffles on the adjacent side. A phenolic resin film is fixedly connected to the outside of the four baffles, and a wear-resistant layer is fixedly connected to the outside of the phenolic resin film.

[0008] Preferably, a support frame is fixedly connected to the opposite side of the four baffles. A support frame is fixedly connected to the upper side of the support frame. A support rod is slidably connected inside the support frame. A pull block is fixedly connected to the upper outer side of the support rod. A second spring is sleeved on the outside of the support rod. A movable plate is fixedly connected to the bottom end of the support rod. Limit blocks are fixedly connected to both sides of the movable plate. The limit blocks are slidably connected inside the limit grooves. The limit grooves are located on both sides of the support frame. Reinforcing components are fixedly connected to both sides of the lower part of the movable plate. The reinforcing components are used to enhance the stability of the baffles during use.

[0009] Preferably, the reinforcing component includes a snap-fit ​​block, which is fixedly connected to the lower two sides of the movable plate, and the snap-fit ​​block is slidably connected inside the snap-fit ​​groove, which is located on the upper side of the reinforcing rod, and the reinforcing rod is slidably connected inside the support frame.

[0010] Preferably, a connecting frame is fixedly connected to the opposite side of the third baffle and the fourth baffle. The connecting frame is rotatably connected to a connecting cylinder via a connecting shaft. A third spring is fixedly connected inside the connecting cylinder. A support assembly is fixedly connected to the bottom end of the third spring. The support assembly is used to improve the stability of the baffle during use.

[0011] Preferably, the support assembly includes a connecting rod, which is fixedly connected to the bottom end of the third spring, slidably connected inside the connecting cylinder, and a base plate is fixedly connected to the bottom end of the connecting rod, with a fixing bolt threaded into the inside of the base plate.

[0012] Preferably, the top end of the second spring is fixedly connected to the upper inside of the support frame, and the bottom end of the second spring is fixedly connected to the upper side of the movable plate.

[0013] Preferably, the fixed cylinder has grooves on both sides, and the sliding block is slidably connected inside the grooves.

[0014] Preferably, guide grooves are provided on both sides of the insertion slot, and the support plate is slidably connected inside the guide grooves.

[0015] Preferably, the fourth baffle has insertion slots on both sides of its front portion, and the insertion block is slidably connected inside the insertion slots.

[0016] Working principle: When using this device, the first and second baffles are initially positioned by the insertion block and insertion slot. During the insertion process, the insertion block pushes the support plate, causing the fixing rod to slide along the fixing cylinder and compress the first spring. When the insertion block reaches the predetermined position, the first spring pushes the fixing rod and support plate, causing the T-shaped locking block to engage with the T-shaped locking slot, completing the automatic locking. This connection method is suitable for large-area template assembly of standardized components, improving assembly efficiency and reducing labor intensity. The third and fourth baffles achieve size adjustment through the sliding cooperation between the connecting slot and the connecting plate, and... The corner connections are secured with connecting bolts to form an integral frame, allowing the formwork to adapt to construction errors in the cross-sectional dimensions of columns, beams, and other components, improving the versatility of the formwork system and reducing the number of specialized formwork units. The supporting plate serves as the concrete forming surface; its phenolic resin film provides a smooth and non-sticky demolding interface, while the wear-resistant layer enhances the durability of the surface layer. This composite surface layer is suitable for fair-faced concrete projects with strict appearance quality requirements, effectively ensuring the flatness and consistency of the formed concrete surface, preventing grout leakage and formwork adhesion. Its wear-resistant properties also make it suitable for multiple reuses. Modular construction helps control long-term operating costs. When using this device, after assembling the four baffles, the worker pulls the lever, causing the support rod to slide upwards along the support frame, compressing the second spring. The support rod then causes the moving plate to rise. The moving plate maintains vertical movement through the engagement of the limiting block and the limiting groove. The moving plate causes the locking block to move upwards, and then the reinforcing rod is inserted into the two support frames. Once the position is determined, the lever is released, and the second spring pushes the support rod downwards, causing the locking block to engage with the locking groove, thus supporting and limiting the reinforcing rod and further reinforcing the two baffles. This effectively enhances the overall stability of the baffle structure and prevents local deformation. By adjusting the angle of the connecting cylinder through the connecting shaft, it maintains a vertical support state on the inclined foundation. The third spring continuously pushes the connecting rod to slide downward inside the connecting cylinder, so that the bottom plate makes full contact with the uneven ground. When encountering soft foundation, the third spring adjusts the support force through automatic extension and retraction to maintain stable contact. After the support height is determined, the fixing bolts are tightened to lock the position of the connecting rod, preventing the concrete pouring vibration from causing shrinkage. This ensures that the formwork is effectively supported under various foundation conditions and ensures long-term stability.

[0017] This invention provides a concrete structure formwork for civil engineering. It has the following beneficial effects:

[0018] 1. This invention achieves rapid template positioning through the cooperation of plug-in blocks and plug-in slots. During the plugging process, the first spring drives the T-shaped locking block and the T-shaped locking slot to automatically lock together, significantly improving the template assembly efficiency. The third and fourth baffles achieve size adjustment through the sliding cooperation of the connecting slot and the connecting plate, forming an overall frame with the connecting bolts, effectively adapting to component cross-sectional size errors and enhancing the versatility of the template. The phenolic resin film on the surface of the bearing plate ensures smooth demolding and concrete surface quality, and the wear-resistant layer improves the durability of the surface layer, meeting the requirements of fair-faced concrete projects. It is also suitable for large-scale construction with multiple turnovers, effectively controlling long-term use costs.

[0019] 2. This invention allows construction workers to pull up the pull block, causing the support rod to rise along the support frame and compress the second spring. This causes the moving plate to move vertically upward through the guide of the limiting block and the limiting groove, which in turn causes the locking block to rise. Subsequently, the reinforcing rod is inserted into the support frame. After releasing the pull block, the second spring pushes the support rod downward, causing the locking block to engage with the locking groove of the reinforcing rod to complete automatic locking. This reinforcement structure effectively enhances the overall stability of the baffle, prevents local deformation, and improves the safety and reliability of the support system.

[0020] 3. This invention adjusts the angle of the connecting cylinder through the connecting shaft to maintain vertical support on inclined foundations; the third spring continuously pushes the connecting rod downward to ensure full contact between the base plate and uneven ground; when encountering soft foundations, the third spring automatically extends and retracts to adjust the support force; after the support height is determined, the fixing bolts are tightened to lock the position of the connecting rod. This structure enables the template to adapt to various foundation conditions, ensuring support effectiveness and long-term stability. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example:

[0032] Please see the appendix Figure 1 - Appendix Figure 6This invention provides a concrete structure formwork for civil engineering, including a first baffle 1 and a second baffle 14. A connecting plate 15 is fixedly connected to the opposite sides of the first baffle 1 and the second baffle 14. The connecting plate 15 is slidably connected inside a connecting groove 16. The connecting grooves 16 are respectively located inside a third baffle 17 and a fourth baffle 19. The third baffle 17 and the fourth baffle 19 are connected to the connecting plate 15 by connecting bolts 18. A connecting assembly is fixedly connected to the adjacent sides of the four baffles. The connecting assembly is used to achieve a better fair-faced concrete effect. Insertion grooves 2 are provided on both sides of the right side of the first baffle 1. A groove 3 is provided on the adjacent side of the insertion grooves 2. Fixing cylinders 4 are fixedly connected to both sides inside the grooves 3. Fixing rods 5 are slidably connected inside the fixing cylinders 4. Sliding blocks 6 are fixedly connected to both sides of the fixed rod 5. A first spring 8 is sleeved on the outside of the fixed cylinder 4 and the fixed rod 5. One end of the first spring 8 is fixedly connected to the inside of the insertion slot 2, and the other end of the first spring 8 is fixedly connected to the side of the support plate 9 that is close to it. The side of the fixed rod 5 that is far away from it is fixedly connected to the support plate 9. A T-shaped locking block 11 is fixedly connected to the side of the support plate 9 that is far away from it. The T-shaped locking block 11 is slidably connected to the inside of the T-shaped locking groove 12. The T-shaped locking groove 12 is set inside the insertion block 13. The insertion block 13 is fixedly connected to both sides of the left side of the second baffle 14. The connecting assembly includes a bearing plate 20. The bearing plate 20 is fixedly connected to the side of the four baffles that is close to it. A phenolic resin film 21 is fixedly connected to the outside of the four baffles. A wear-resistant layer 22 is fixedly connected to the outside of the phenolic resin film 21.

[0033] When using this device, the first baffle 1 and the second baffle 14 are initially positioned by the insertion block 13 and the insertion slot 2. During the insertion process, the insertion block 13 pushes the support plate 9, causing the fixing rod 5 to slide along the fixing cylinder 4 and compress the first spring 8. When the insertion block 13 reaches the predetermined position, the first spring 8 pushes the fixing rod 5 and the support plate 9, causing the T-shaped locking block 11 to engage with the T-shaped locking slot 12 to complete automatic locking. This connection method is suitable for large-area template assembly of standardized components, which can improve assembly efficiency and reduce labor intensity. The third baffle 17 and the fourth baffle 19 achieve size adjustment through the sliding cooperation between the connecting slot 16 and the connecting plate 15, and through... The corner connections are fixed by connecting bolts 18 to form an integral frame, enabling the formwork to adapt to construction errors in the cross-sectional dimensions of components such as columns and beams, improving the versatility of the formwork system and reducing the number of special formworks. The set bearing plate 20 serves as the concrete forming surface, and its surface phenolic resin film 21 provides a smooth and non-adhesive demolding interface, while the wear-resistant layer 22 enhances the durability of the surface layer. This composite surface layer is suitable for fair-faced concrete projects with strict requirements for appearance quality, effectively ensuring the flatness and consistency of the formed concrete surface, preventing grout leakage and sticking to the formwork. At the same time, its wear-resistant properties are suitable for large-scale construction with multiple turnovers, which helps to control long-term use costs.

[0034] Please see the appendix Figure 1Appendix Figure 2 Appendix Figure 7 A support frame 23 is fixedly connected to the side of the four baffles that is furthest apart. A support frame 24 is fixedly connected to the upper side of the support frame 23. A support rod 25 is slidably connected inside the support frame 24. A pull block 26 is fixedly connected to the upper outside of the support rod 25. A second spring 27 is sleeved on the outside of the support rod 25. A movable plate 28 is fixedly connected to the bottom end of the support rod 25. Limiting blocks 29 are fixedly connected to both sides of the movable plate 28. The limiting blocks 29 are slidably connected inside the limiting grooves 30. The limiting grooves 30 are located on both sides of the support frame 24. Reinforcing components are fixedly connected to both sides of the lower part of the movable plate 28. The reinforcing components are used to enhance the stability of the baffles during use. The reinforcing components include a snap-fit ​​block 31. The snap-fit ​​block 31 is fixedly connected to both sides of the lower part of the movable plate 28. The snap-fit ​​block 31 is slidably connected inside the snap-fit ​​groove 32. The snap-fit ​​groove 32 is located on the upper side of the reinforcing rod 33. The reinforcing rod 33 is slidably connected inside the support frame 23.

[0035] When using this device, after the initial assembly of the four baffles is completed, the construction personnel can activate the additional support system to enhance structural stability. The construction personnel pull the pull block 26 upward, causing the support rod 25 to slide smoothly upward along the inner wall of the support frame 24. During this process, the second spring 27 sleeved on the outside of the support rod 25 is compressed simultaneously. The upward movement of the support rod 25 causes the movable plate 28 fixed at its bottom end to move upward synchronously. The limiting blocks 29 on both sides of the movable plate 28 slide precisely along the limiting grooves 30 inside the support frame 24 to ensure that the movable plate 28 always maintains a vertical movement trajectory. As the movable plate 28 rises, the locking blocks 31 fixed on both sides of its lower part are also raised. At this time, the construction personnel can accurately insert the reinforcing rod 33 into the preset space between the two support frames 23. After the reinforcing rod 33 is in place, the pull block 26 is released, and the second spring... The restoring force of spring 27 pushes the support rod 25 downward, which in turn drives the moving plate 28 and the locking block 31 to move downward simultaneously. During this process, the locking block 31 is precisely embedded in the locking groove 32 at the upper end of the reinforcing rod 33, forming a stable mechanical interlock. This reinforcement system achieves rapid installation and reliable fixation of the reinforcing rod 33 through a spring-driven automatic locking mechanism. The introduction of the reinforcing rod 33 effectively disperses the lateral load borne by the baffle, significantly improving the overall rigidity and deformation resistance of the template system. The matching design of the limiting block 29 and the limiting groove 30 ensures the accuracy of the force transmission path, while the preload of the second spring 27 ensures the long-term stability of the connection node under vibration conditions. This structure is particularly suitable for high-rise buildings or large-volume concrete pouring, and can effectively prevent quality problems such as template bulging and displacement.

[0036] Please see the appendix Figure 1 Appendix Figure 8A connecting frame 34 is fixedly connected to the opposite side of the third baffle 17 and the fourth baffle 19. The connecting frame 34 is rotatably connected to a connecting cylinder 36 via a connecting shaft 35. A third spring 37 is fixedly connected inside the connecting cylinder 36. A support assembly is fixedly connected to the bottom end of the third spring 37. The support assembly is used to improve the stability of the baffle during use. The support assembly includes a connecting rod 38, which is fixedly connected to the bottom end of the third spring 37 and slidably connected inside the connecting cylinder 36. A base plate 39 is fixedly connected to the bottom end of the connecting rod 38, and a fixing bolt 40 is threaded inside the base plate 39.

[0037] When using this device, the angle of the connecting cylinder 36 is adjusted by the connecting shaft 35 to maintain a vertical support state on the inclined foundation. The third spring 37 continuously pushes the connecting rod 38 to slide downward in the connecting cylinder 36, so that the base plate 39 makes full contact with the uneven ground. When encountering soft foundation, the third spring 37 adjusts the support force by automatically extending and retracting to maintain stable contact. After the support height is determined, the fixing bolt 40 is tightened to lock the position of the connecting rod 38 to prevent the formwork from shrinking due to concrete pouring vibration, ensuring that the formwork is effectively supported under various foundation conditions and ensuring long-term stability.

[0038] Please see the appendix Figure 5 Appendix Figure 6 Appendix Figure 7 The top end of the second spring 27 is fixedly connected to the upper side inside the support frame 24, and the bottom end of the second spring 27 is fixedly connected to the upper side of the moving plate 28; both sides of the fixed cylinder 4 are provided with sliding grooves 7, and the sliding block 6 is slidably connected inside the sliding grooves 7; both sides of the insertion groove 2 are provided with guide grooves 10, and the support plate 9 is slidably connected inside the guide grooves 10; both sides of the front part of the fourth baffle 19 are provided with insertion grooves 2, and the insertion block 13 is slidably connected inside the insertion grooves 2.

[0039] The top end of the second spring 27 is firmly fixed to the upper side of the inside of the support frame 24, and its bottom end is reliably fixed to the upper side of the moving plate 28. This connection method allows the second spring 27 to provide a continuous and stable elastic restoring force to the moving plate 28. The fixed cylinder 4 has longitudinally extending grooves 7 on both sides, and the sliding block 6 is precisely slidably connected inside the grooves 7. This mating structure ensures the stability and straightness of the fixed rod 5 when sliding inside the fixed cylinder 4. The two sides of the insertion groove 2 have vertical guide grooves 10, and the two ends of the support plate 9 are respectively slidably connected inside the corresponding guide grooves 10, so that the support plate 9 always maintains the correct movement trajectory during movement. The front two sides of the fourth baffle 19 have symmetrical insertion grooves 2, and the insertion block 13 can be slidably inserted and connected inside the insertion groove 2, so that the fourth baffle 19 can achieve a quick and reliable insertion connection with the adjacent baffle, improving the assembly efficiency and connection reliability of the template system.

[0040] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
