Description

Technical Field

[0001] This invention relates to the field of rock wool strip formwork technology, specifically to a reinforced rock wool strip composite non-removable building formwork that is easy to cut and splice. Background Technology

[0002] In the construction industry, reinforced rock wool strip composite formwork is an important construction material. It is mainly used during concrete pouring to provide support for concrete forming and to provide insulation and heat preservation. By combining rock wool strips with specific structural frames, a formwork system with certain strength and insulation performance is formed. This system is widely used in building exterior walls, roofs, and other parts, helping to improve the energy efficiency and structural stability of buildings, aligning with the modern trend of green, environmentally friendly, and energy-saving construction.

[0003] Traditional reinforced rock wool strip composite building formwork has many shortcomings. In terms of installation convenience, the installation and fixing of rock wool strips is complex, usually requiring additional tools and a large amount of manpower, and the installation efficiency is low, making it difficult to meet the rapid progress requirements of large-scale construction. Furthermore, the formwork has poor versatility and is not well-suited to different sizes of rock wool strips. Even slight deviations in the size of the rock wool strips can lead to problems such as insecure fixing and detachment, requiring frequent formwork replacements, increasing construction costs and time. In addition, the connection methods between the formwork are not robust or efficient enough. When assembled into large-area walls, the overall integrity and structural strength are insufficient, making them prone to displacement and deformation during construction. Especially in the face of natural disasters such as earthquakes, it is difficult to effectively maintain the integrity of the wall surface, failing to guarantee the quality and safety of building construction. Therefore, improvements and optimizations are urgently needed. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] This invention provides a composite, non-removable building formwork made of reinforced rock wool strips that is easy to cut and splice, solving the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a composite, non-removable building template made of reinforced rock wool strips that is easy to cut and splice, comprising a central frame, the central frame being concave, and insert rods elastically and symmetrically inserted into the upper and lower surfaces of the central frame, with an extrusion cover fixedly connected to the end of the insert rod away from the central frame; and further comprising:

[0008] A fixing component is fixedly installed inside the central frame, and the fixing component works in conjunction with the extrusion cover;

[0009] The connecting components are fixedly connected to the side surfaces of the central frame and the extrusion cover, respectively, and the connecting components and the fixing components work together.

[0010] The fixing component includes a mounting plate, which is fixedly connected to the inner surface of the center frame. A first sliding groove is formed through the interior of the mounting plate. Insertion plates are symmetrically slidably arranged in the first sliding groove. The outer sides of the insertion plates are disposed through the mounting plate. The surfaces of the two insertion plates that are close to each other are symmetrically inclined. A support plate is fixedly connected to the inner surface of the center of the first sliding groove. Guide rods are fixedly connected to the two surfaces of the support plate that are close to the insertion plates. The two ends of the guide rods are slidably inserted into the insertion plates by springs.

[0011] Preferably, a driving block is slidably attached to the inclined surfaces of the two plug-in plates. The driving block is configured as a boss. A second sliding groove is provided through the side of the mounting plate away from the first sliding groove. A third sliding groove is symmetrically provided in the wall of the mounting plate between the second sliding groove and the first sliding groove. The first sliding groove and the second sliding groove are connected through the third sliding groove.

[0012] Preferably, a sliding plate is symmetrically slidably installed inside the second sliding groove, and the sliding plate is fixedly connected to the driving block through the third sliding groove. Support plates are symmetrically fixedly connected to both sides of the second sliding groove inside the mounting plate, and a driving rod is rotatably connected to the inner surface of the support plate.

[0013] Preferably, the two ends of the drive rod are provided with threads, and the threads at both ends of the drive rod are symmetrically arranged, and the two ends of the drive rod are connected to the sliding plate by threads.

[0014] Preferably, a pull rod is symmetrically fixedly connected to the surface of the sliding plate near the support plate, and an adhesive plate is fixedly connected to the end of the pull rod away from the sliding plate. The adhesive plate is disposed on the outside of the mounting plate and is attached to the inner surface of the central frame. The end of the adhesive plate away from the mounting plate is fixedly connected to the surface of the extrusion cover near the mounting plate.

[0015] Preferably, the fixing component further includes a compression block, which is slidably inserted into the surface of the compression cover near the mounting plate. Slide rods are symmetrically fixedly connected to both sides of the inside of the compression cover. The two sides of the compression block are elastically slidably sleeved on the outer surface of the slide rods by springs. A compression bladder is fixedly connected to the surface of the compression block away from the mounting plate. The compression bladder is disposed inside the compression cover. The side of the compression bladder away from the compression block is fixedly connected to the inner surface of the side of the compression cover connected to the connecting component.

[0016] Preferably, telescopic rods are symmetrically fixedly embedded on the inner surfaces of both sides of the central frame. The internal cavity of the telescopic rod is connected to the internal cavity of the compression bladder through a connecting pipe. One end of the connecting pipe passes through the compression bladder and is connected to the compression bladder, while the other end passes through the central frame and is connected to the interior of the telescopic rod. A compression plate is fixedly connected to the output end of the telescopic rod. The compression plate and the mounting plate are arranged parallel to each other. A buffer plate is fixedly connected to the surface of the compression plate near the mounting plate. The buffer plate is made of rubber material and is hollow inside.

[0017] Preferably, the connecting assembly includes a first fixing seat, which is fixedly installed on the upper surface of the top extrusion cover and simultaneously fixedly installed on the side surface of the central frame. A second fixing seat is fixedly installed on the lower surface of the bottom extrusion cover, and a second fixing seat is also fixedly installed on the surface of the central frame away from the first fixing seat. A connecting plate is fixedly connected to the surface of the second fixing seat away from the extrusion cover. A limiting post is fixedly connected to the first fixing seat, and the first and second fixing seats are connected by the mutual insertion of the connecting plate and the limiting post.

[0018] Preferably, the limiting post is hollow inside, and the internal cavity of the limiting post communicates with the internal cavity of the buffer plate. A locking plate is elastically slidably connected to the side of the limiting post near the extrusion cover. An alignment groove is formed on the surface of the connecting plate near the second fixing seat. When the first and second fixing seats are inserted through the limiting post and connecting plate, the locking plate and the alignment groove are aligned. When the template needs to be installed, several templates can be prepared according to the installation requirements. Then, several templates are inserted into each other through the first fixing seat and connecting plate until a complete building support wall is formed and placed horizontally. Next, the extrusion cover is pulled by a tensioning device, increasing the cavity between the extrusion cover and the central frame. Then, rock wool strips are placed into the central frame, and the extrusion cover is driven to reset and clamp the rock wool strips. Finally, the assembled support wall is fixedly installed on the building wall to complete the installation. When the extrusion cover is stretched, it will be simultaneously stretched by the bonding plate. The moving pull rod moves, causing the drive rod to rotate under the action of the threads. This causes the two sliding plates on the same drive rod to move away from each other. The symmetrically distributed threads at both ends of the drive rod cause the two extrusion covers on the same central frame to move outwards synchronously. As the sliding plates move, they simultaneously drive the drive block to slide outwards along the third slide groove. At this point, the plug-in plates begin to retract under the spring force, and finally, the outer ends of the plug-in plates are retracted into the mounting plate. Then, the rock wool strip is placed into the central frame, and the rock wool strip is fastened to the mounting plate. After the rock wool strip is placed, the drive extrusion cover resets. As the extrusion cover resets, the pull rod drives the sliding plate to reset, which in turn drives the drive rod to rotate in the opposite direction. This causes the two drive blocks on the same central frame to move closer together, thus starting to compress the plug-in plate and causing it to move outwards from the mounting plate. Finally, the outer side of the plug-in plate protrudes from the mounting plate and engages with the rock wool strip.

[0019] (III) Beneficial Effects

[0020] This invention provides a composite, non-removable building formwork made of reinforced rock wool strips that is easy to cut and splice. It has the following beneficial effects:

[0021] (I) This composite, non-removable building formwork for reinforced rock wool strips, which is easy to cut and splice, can quickly and simultaneously fix the rock wool strips during installation by setting fixed components, preventing the rock wool strips from falling off after installation. This greatly improves the working stability of the formwork. At the same time, the stretchable extrusion cover can accommodate rock wool strips of various lengths, making it easy to install the rock wool strips after cutting. This greatly improves the applicability of the formwork and avoids the need to repeatedly replace the formwork. In addition, the combination of multiple formworks also greatly improves the installation flexibility.

[0022] (II) This reinforced rock wool strip composite non-removable building template, which is easy to cut and splice, will cause the upper and lower surfaces of the rock wool strip to contact the outer surface of the extrusion block as the extrusion cover is reset, and will continuously extrude the extrusion block. As the extrusion pressure increases, the extrusion block will start to move into the extrusion cover, thereby extruding the extrusion bladder and increasing the air pressure inside the extrusion bladder. This will then be transmitted to the inside of the telescopic rod, forcing the output end of the telescopic rod to expand outward, thereby pushing the extrusion plate to move towards the side of the installation plate, and finally adhering to the side surface of the rock wool strip. In this way, the rock wool strip is fixed by a combination of multiple fixing methods, which greatly improves the fixing effect of the rock wool strip and facilitates subsequent unified installation.

[0023] (III) This easily cut and spliced ​​reinforced rock wool strip composite non-removable building formwork features a buffer plate that acts as a buffer medium when the extrusion plate and rock wool strips are compressed against each other. The buffer plate cushions the extrusion pressure between the rock wool strips and the extrusion plate, preventing excessive pressure from deforming the sides of the rock wool strips. Simultaneously, the deformable nature of the buffer plate allows the formwork to accommodate rock wool strips of different widths, further improving its adaptability. Furthermore, when the buffer plate is compressed, it transmits its internal air pressure to the internal cavity of the limiting column, forcing an increase in the internal cavity pressure of the limiting column, thereby forcing the limiting column to... The locking plate inside the positioning column moves outward towards the limiting column and gradually moves into the alignment groove of the connecting plate, locking the connecting plate with the No. 1 fixing seat. This allows the templates to be fixed and locked together simultaneously after the rock wool strips are installed, further improving the stability of the template assembly. At the same time, the joint form also significantly improves the connection strength between the templates, greatly enhancing the structural strength of the entire building wall structure formed by this template assembly. This not only significantly improves the structural strength of the building wall but also helps maintain the integrity of the wall surface during earthquakes, reducing the safety hazards caused by wall collapse.

[0033] 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.

[0034] First embodiment: as follows Figures 1 to 8 As shown, the present invention provides a technical solution: a composite, non-removable building template made of reinforced rock wool strips that is easy to cut and splice, comprising a central frame 1, the central frame 1 being concave, and insert rods 2 being elastically and symmetrically inserted into the upper and lower surfaces of the central frame 1, with an extrusion cover 3 fixedly connected to the end of the insert rod 2 away from the central frame 1, and further comprising:

[0035] Fixing component 4 is fixedly installed inside the central frame 1, and works in conjunction with the extrusion cover 3;

[0036] Connecting component 5 is fixedly connected to the side surfaces of the central frame 1 and the extrusion cover 3 respectively. Connecting component 5 and fixing component 4 work together.

[0037] The fixing component 4 includes a mounting plate 41, which is fixedly connected to the inner surface of the middle part of the central frame 1. A first groove 42 is opened through the interior of the mounting plate 41. A plug-in plate 43 is symmetrically slidably arranged in the first groove 42. The outer side of the plug-in plate 43 is set through the mounting plate 41. The surfaces of the two plug-in plates 43 that are close to each other are symmetrically inclined. A bearing plate 44 is fixedly connected to the inner surface of the middle part of the first groove 42. Guide rods 45 are fixedly connected through the two surfaces of the bearing plate 44 that are close to the plug-in plates 43. The two ends of the guide rods 45 are slidably inserted into the plug-in plates 43 by springs.

[0038] Two plug-in plates 43 are slidably fitted with drive blocks 46, which are configured as bosses. A second slide groove 47 is provided through the side of the mounting plate 41 away from the first slide groove 42. A third slide groove 48 is symmetrically provided in the wall of the mounting plate 41 between the second slide groove 47 and the first slide groove 42. The first slide groove 42 and the second slide groove 47 are connected through the third slide groove 48.

[0039] A sliding plate 49 is symmetrically slidably installed inside the second slide groove 47. The sliding plate 49 is fixedly connected to the drive block 46 through the third slide groove 48. Support plates 410 are symmetrically fixedly connected to both sides of the second slide groove 47 inside the mounting plate 41. A drive rod 411 is rotatably connected to the inner surface of the support plate 410.

[0040] The drive rod 411 has threads at both ends, and the threads at both ends of the drive rod 411 are symmetrically arranged. The two ends of the drive rod 411 are connected to the sliding plate 49 by threads.

[0041] A pull rod 412 is symmetrically fixedly connected to the surface of the sliding plate 49 near the support plate 410. A bonding plate 413 is fixedly connected to the end of the pull rod 412 away from the sliding plate 49. The bonding plate 413 is disposed on the outside of the mounting plate 41 and is attached to the inner surface of the central frame 1. The end of the bonding plate 413 away from the mounting plate 41 is fixedly connected to the surface of the extrusion cover 3 near the mounting plate 41.

[0042] Second embodiment: as follows Figures 1 to 8 As shown, the fixing component 4 also includes a pressing block 414, which is slidably inserted into the surface of the pressing cover 3 near the mounting plate 41. Sliding rods 415 are symmetrically fixedly connected to both sides of the inside of the pressing cover 3. The two sides of the pressing block 414 are elastically slidably sleeved on the outer surface of the sliding rods 415 by springs. A pressing bladder 416 is fixedly connected to the surface of the pressing block 414 away from the mounting plate 41. The pressing bladder 416 is disposed inside the pressing cover 3. The side of the pressing bladder 416 away from the pressing block 414 is fixedly connected to the inner surface of the pressing cover 3 on the side connected to the connecting component 5.

[0043] Telescopic rods 417 are symmetrically fixedly embedded on the inner surfaces of both sides of the central frame 1. The internal cavity of the telescopic rod 417 is connected to the internal cavity of the compression bladder 416 through a connecting pipe. The output end of the telescopic rod 417 is fixedly connected to a compression plate 418. The compression plate 418 and the mounting plate 41 are arranged parallel to each other. A buffer plate 419 is fixedly connected to the surface of the compression plate 418 near the mounting plate 41. The buffer plate 419 is made of rubber material, and the interior of the buffer plate 419 is hollow.

[0044] Third embodiment: as follows Figures 1 to 8 As shown, the connecting assembly 5 includes a first fixing seat 51, which is fixedly installed on the upper surface of the top extrusion cover 3. The first fixing seat 51 is also fixedly installed on the side surface of the central frame 1. A second fixing seat 52 is fixedly installed on the lower surface of the bottom extrusion cover 3. A second fixing seat 52 is also fixedly installed on the surface of the central frame 1 away from the first fixing seat 51. A connecting plate 53 is fixedly connected to the surface of the second fixing seat 52 away from the extrusion cover 3. A limiting post 54 is fixedly connected to the first fixing seat 51. The connection between the first fixing seat 51 and the second fixing seat 52 is completed by the mutual insertion of the connecting plate 53 and the limiting post 54.

[0045] The interior of the limiting post 54 is hollow, and the internal cavity of the limiting post 54 is connected to the internal cavity of the buffer plate 419. The limiting post 54 is elastically slidably connected to the snap plate 55 on the side near the compression cover 3. The surface of the connecting plate 53 near the second fixing seat 52 is provided with an alignment groove 56. When the first fixing seat 51 and the second fixing seat 52 are inserted through the limiting post 54 and the connecting plate 53, the snap plate 55 and the alignment groove 56 are aligned with each other.

[0046] During operation, when template installation is required, several templates are prepared according to the installation needs. Then, these templates are interlocked using the first fixing seat 51 and connecting plate 53 until a complete building support wall is formed and placed horizontally. Next, the extrusion cover 3 is pulled by a tensioning device, increasing the cavity between the extrusion cover 3 and the central frame 1. Rock wool strips are then placed into the central frame 1, and the extrusion cover 3 is driven to reset, clamping the rock wool strips. Finally, the assembled support wall is fixedly installed on the building wall to complete the installation. When the extrusion cover 3 is stretched, the connecting plate 413 synchronously pulls the pull rod 412, causing the drive rod 411 to rotate under the action of the threads, thus achieving the desired effect. Two sliding plates 49 on a drive rod 411 begin to move away from each other. This is achieved by the symmetrically distributed threads at both ends of the drive rod 411, causing the two extrusion covers 3 on the same central frame 1 to move outwards synchronously. As the sliding plates 49 move, they synchronously drive the drive block 46 to slide outwards along the third slide groove 48. At this time, the insertion plates 43 begin to retract under the spring force, eventually retracting their outer ends into the mounting plate 41. Then, a rock wool strip is placed into the central frame 1, fastening it to the mounting plate 41. After the rock wool strip is placed, the drive extrusion cover 3 resets. This reset of the extrusion cover 3 drives the sliding plates 49 to reset via the pull rod 412, thereby causing the drive rod 411 to rotate in the opposite direction, thus promoting the movement of the two extrusion covers 3 on the same central frame 1. The two drive blocks 46 on the core frame 1 begin to move closer to each other, thus squeezing the plug-in plate 43. This causes the plug-in plate 43 to move outward from the mounting plate 41. Eventually, the outer side of the plug-in plate 43 protrudes from the mounting plate 41 and engages with the rock wool strip. By setting the fixing component 4, the rock wool strip can be fixed simultaneously and quickly during installation, preventing it from falling off after installation. This greatly improves the working stability of the template. Furthermore, the stretchable extrusion cover 3 can accommodate rock wool strips of various lengths, facilitating installation even after cutting. This significantly improves the applicability of the template and avoids the need for repeated template replacements. The combination of multiple templates also greatly improves installation efficiency. The system offers flexibility. As the compression cover 3 resets, the upper and lower surfaces of the rock wool strip first contact the outer surface of the compression block 414, continuously compressing it. As the compression pressure increases, the compression block 414 begins to move inwards from the compression cover 3, thus compressing the compression bladder 416. This increases the air pressure inside the compression bladder 416, transferring it to the telescopic rod 417. This forces the output end of the telescopic rod 417 to expand outwards, pushing the compression plate 418 towards the mounting plate 41, ultimately fitting it against the side surface of the rock wool strip. This multi-method combination significantly improves the fixing effect of the rock wool strip, facilitating subsequent unified installation.When the extrusion plate 418 and the rock wool strip are pressed together, the buffer plate 419 acts as a buffer medium. The buffer plate 419 buffers the extrusion force between the rock wool strip and the extrusion plate 418, preventing excessive extrusion force from causing the sides of the rock wool strip to be deformed. At the same time, the deformable performance of the buffer plate 419 also allows this template to accommodate rock wool strips of different widths, further improving the adaptability of this template. When the buffer plate 419 is compressed, it will transport its internal air pressure to the internal cavity of the limiting post 54, forcing the internal cavity pressure of the limiting post 54 to increase, thereby forcing the locking mechanism inside the limiting post 54 to engage. The composite plate 55 moves outward from the limiting post 54 and gradually moves into the alignment groove 56 of the connecting plate 53, engaging the connecting plate 53 with the first fixing seat 51. This allows for simultaneous fixing and engaging of the templates after the rock wool strips are installed, further improving the stability of the template assembly. Simultaneously, the combined formwork significantly enhances the connection strength between the templates, resulting in a substantial increase in the structural strength of the entire building wall structure. This not only significantly improves the structural strength of the building wall but also helps maintain the integrity of the wall surface during earthquakes, reducing the safety hazards caused by wall collapse.
