Description

Technical Field

[0001] This utility model relates to the field of building formwork technology, and in particular to a splicing building formwork. Background Technology

[0002] Construction formwork is a temporary support structure, manufactured according to design requirements, to shape concrete structures and components into specified positions and geometric dimensions, maintain their correct position, and bear the self-weight of the formwork and external loads acting on it. The purpose of formwork engineering is to ensure the quality and safety of concrete projects, accelerate construction progress, and reduce project costs.

[0003] According to the announcement number CN221168637U, a building formwork that is easy to assemble is proposed. This building formwork has a simple structure and is easy to operate. Two splicing slots are set on the surface of the building formwork, and splicing blocks are set on the other surface. The two building formworks are snapped together by inserting the blocks into the slots. The snap-fit ​​is fixed by the limiting block structure on the plug rod and the main body of the bolt, thereby reducing the operation process, facilitating installation and disassembly, meeting different actual use needs, and is suitable for promotion.

[0004] In construction engineering, formwork systems are widely used for concrete pouring and forming. Traditional formwork is mostly spliced ​​and fixed by bolts or welding. Although the connection is firm, the installation and dismantling efficiency is low. In order to improve construction efficiency, some formwork using plug-in connection has emerged in recent years. However, such plug-in structure usually relies on clips for fixing. Under long-term use, it is prone to deformation and breakage, resulting in loosening or even falling off, affecting the overall structural stability. In addition, the existing plug-in structure lacks an effective locking mechanism, which can easily come loose when subjected to external impact or concrete pressure, posing a safety hazard.

[0005] Therefore, there is an urgent need to provide a modular building formwork to solve the above problems. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a splicing building template.

[0007] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: providing a splicing building template, including a first building template, a second building template attached to one side of the first building template, and a square steel frame welded and fixed to one side of both the first building template and the second building template.

[0008] Both square steel frames are welded and fixed with grid-shaped reinforcing ribs inside, both square steel frames are provided with elliptical insertion holes inside, and both grid-shaped reinforcing ribs are provided with C-shaped sliding grooves inside.

[0009] The first building template is provided with a splicing mechanism on one side for splicing the first building template and the second building template;

[0010] The inside of the grid-shaped reinforcing rib is provided with a locking mechanism to fix the insertion state of the insertion mechanism, and one side of the grid-shaped reinforcing rib is provided with a limiting mechanism to fix the retraction state of the insertion mechanism.

[0011] Through the above technical solutions, both the first and second building formwork are reinforced with square steel frames and grid-like reinforcing bars to enhance the frame strength, effectively resisting the pressure during concrete pouring.

[0012] The present invention is further configured such that: the plug-in mechanism includes an installation guide rail fixed to one side of the first building template, an installation plate is slidably installed on the outside of the installation guide rail, and three plug-in shafts are rotatably installed inside the installation plate.

[0013] Through the above technical solution, the plug-in rotating shaft and the mounting plate move through the mounting guide rail. When the mounting plate moves to the apex of one end of the mounting guide rail, the plug-in rotating shaft extends into the square steel frame of another building formwork. When the mounting plate retracts through the mounting guide rail, the other end of the plug-in rotating shaft is on the same horizontal line as the limiting mechanism.

[0014] The present invention is further configured such that: one end of the plug-in rotating shaft is fixed with a plug-in limiting block, both ends of the plug-in limiting block are respectively tightly fitted to the inner wall of the square steel frame, and a plug-in anti-detachment block is fixed to the outside of the plug-in rotating shaft.

[0015] Through the above technical solution, the plug-in rotating shaft and the plug-in limiting block can be inserted into the elliptical plug-in hole of the square steel frame. When the plug-in rotating shaft rotates 180 degrees, the plug-in rotating shaft can be connected to the square steel frame of another building template through the plug-in limiting block. The plug-in anti-detachment block will fit against one side of the square steel frame, thereby limiting its position.

[0016] The present invention is further configured such that: each of the three plug-in rotating shafts has an L-shaped rotating rod fixed at one end, and a synchronous connecting plate is rotatably installed at one end of each of the three L-shaped rotating rods.

[0017] With the above technical solution, when one plug-in shaft rotates, the other two plug-in shafts will rotate accordingly via the L-shaped rotating rod and the synchronous connecting plate, which facilitates the installation and disassembly of the plug-in shafts.

[0018] The present invention is further configured such that: the locking mechanism includes two locking sleeve plates slidably installed inside the C-shaped sliding groove with cross-shaped reinforcing ribs, one end of each of the two locking sleeve plates is fixed with a sleeve bolt, and the external threads of the two sleeve bolts are fitted with fixing nuts.

[0019] The above technical solution involves installing two locking sleeves onto the outside of the L-shaped rotating rod and the synchronous connecting plate, thereby locking and fixing the three plug-in rotating shafts through the L-shaped rotating rod. The two locking sleeves are then fixed by sleeve bolts and fixing nuts.

[0020] The present invention is further configured such that: both ends of one side of the first building template are fixed with mounting columns, and two first bolts are threaded on the inner of each of the two mounting columns, with one end of the first bolt penetrating and extending into the interior of the locking sleeve plate.

[0021] With the above technical solution, after the two locking sleeves are retracted, the first bolt is rotated by hand to fix the locking sleeves by the mounting post, preventing accidental ejection.

[0022] The present invention is further configured such that: the limiting mechanism includes an installation slide rail fixed to one side of the grid reinforcing rib, an installation slide plate is slidably installed on the outside of the installation slide rail, two L-shaped limiting plates are fixed at the top of the installation slide plate, and a second bolt is threaded on the inside of the installation slide plate, one end of which passes through and extends into the inside of the installation slide rail.

[0023] With the above technical solution, after the insertion mechanism is retracted, the second bolt is loosened, and the sliding plate and L-shaped limiting plate are moved and installed so that the L-shaped limiting plate is embedded in one side of the L-shaped rotating rod, thereby limiting and fixing the insertion mechanism.

[0024] The beneficial effects of this utility model are as follows:

[0025] 1. This utility model, by providing a plug-in mechanism, can splice and fix the first and second building templates. The combination of the square steel frame and the plug-in rotating shaft greatly improves the connection strength between the templates, effectively resists the pressure during concrete pouring, and reduces the risk of deformation. Compared with the traditional nail or bolt connection method, the operation of this device is simpler and faster. The connection can be completed simply by inserting the plug-in rotating shaft into the plug-in slot of the square steel frame. Then, by rotating the plug-in rotating shaft, reinforcement can be achieved through the plug-in limiting block, which greatly improves the construction efficiency.

[0026] 2. This utility model is equipped with a locking mechanism and a limiting mechanism. The locking mechanism can lock the insertion state of the insertion mechanism, so that the template remains stable during the pouring process, avoiding displacement or loosening caused by vibration or other external forces, and ensuring construction safety. The limiting mechanism can limit and fix the retracted state of the insertion mechanism, ensuring the stability of the insertion mechanism in the retracted state and preventing accidental ejection.

[0037] Please see Figures 1-8A type of interlocking building formwork includes a first building formwork 1, a second building formwork 2 attached to one side of the first building formwork 1, and square steel frames 3 welded and fixed to one side of both the first and second building formwork 1. A grid-like reinforcing rib 4 is welded and fixed inside each of the two square steel frames 3, and each of the two square steel frames 3 has an elliptical insertion hole inside. Each of the two grid-like reinforcing ribs 4 has a C-shaped groove inside. An insertion mechanism 5 for splicing the first building formwork 1 and the second building formwork 2 is provided on one side of the first building formwork 1. The insertion mechanism 5 includes components fixed to the first building formwork 1. A mounting guide rail 501 is mounted on one side. A mounting plate 502 is slidably mounted on the outside of the mounting guide rail 501. Three plug-in rotating shafts 503 are rotatably mounted inside the mounting plate 502. One end of each plug-in rotating shaft 503 is fixed with a plug-in limiting block 504. Both ends of the plug-in limiting block 504 are tightly fitted to the inner wall of the square steel frame 3. A plug-in anti-detachment block 505 is fixed to the outside of each plug-in rotating shaft 503. An L-shaped rotating rod 506 is fixed to the other end of each of the three plug-in rotating shafts 503. A synchronous connecting plate 507 is rotatably mounted on one end of each of the three L-shaped rotating rods 506. The first building formwork 1 and the second building... Both formwork 2 are reinforced with square steel frames 3 and grid-like reinforcing ribs 4 to effectively resist the pressure during concrete pouring. When connecting the first formwork 1 and the second formwork 2, the insertion shaft 503 and the mounting plate 502 are moved by hand along the mounting guide rail 501. When the mounting plate 502 moves to the apex of the mounting guide rail 501, the insertion shaft 503 extends into the square steel frame 3 of the other formwork. The insertion shaft 503 and the insertion limiting block 504 can be inserted into the elliptical insertion hole of the square steel frame 3. The insertion shaft 503 is then manually inserted into the square steel frame 3. 03. When one plug-in rotating shaft 503 rotates, the other two plug-in rotating shafts 503 will rotate accordingly through the L-shaped rotating rod 506 and the synchronous connecting plate 507, which facilitates the installation and disassembly of the plug-in rotating shaft 503. The plug-in rotating shaft 503 can be connected to the square steel frame 3 of another building template through the plug-in limiting block 504. The plug-in anti-detachment block 505 will fit against one side of the square steel frame 3 to limit it. When the mounting plate 502 is retracted through the mounting guide rail 501, the other end of the plug-in rotating shaft 503 is exactly on the same horizontal line as the limiting mechanism 7.

[0038] like Figures 2-6As shown, the internal part of the grid-shaped reinforcing rib 4 is equipped with a locking mechanism 6 to fix the insertion state of the insertion mechanism 5. The locking mechanism 6 includes two locking sleeve plates 601 that are slidably installed inside the C-shaped groove of the grid-shaped reinforcing rib 4. One end of each locking sleeve plate 601 is fixed with a sleeve bolt 602. The external threads of the two sleeve bolts 602 are fitted with fixing nuts 603. Both ends of one side of the first building formwork 1 are fixed with mounting square columns 604. The internal threads of each of the two mounting square columns 604 are fitted with two first bolts 605. One end of bolt 605 passes through and extends into the interior of locking sleeve 601. Two locking sleeves 601 are fitted onto the outside of L-shaped rotating rod 506 and synchronous connecting plate 507. The three plug-in rotating shafts 503 are then locked and fixed by L-shaped rotating rod 506. The two locking sleeves 601 are fixed by sleeve bolt 602 and fixing nut 603. After the two locking sleeves 601 are retracted, the first bolt 605 is rotated by hand to fix the locking sleeves 601 by mounting square post 604 to prevent accidental pop-out.

[0039] like Figures 3-8 As shown, a limiting mechanism 7 is provided on one side of the grid-shaped reinforcing rib 4 to fix the retracted state of the insertion mechanism 5. The limiting mechanism 7 includes an installation slide rail 701 fixed to one side of the grid-shaped reinforcing rib 4. An installation slide plate 702 is slidably installed on the outside of the installation slide rail 701. Two L-shaped limiting plates 703 are fixed to the top of the installation slide plate 702. A second bolt 704 is threaded inside the installation slide plate 702, with one end penetrating and extending into the installation slide rail 701. When the insertion mechanism 5 is retracted, the second bolt 704 is loosened, and the installation slide plate 702 and the L-shaped limiting plate 703 are moved so that the L-shaped limiting plate 703 is embedded in one side of the L-shaped rotating rod 506, thereby limiting and fixing the insertion mechanism 5.

[0040] In use, both the first and second formwork templates are reinforced with square steel frames 3 and grid-like reinforcing ribs 4 to effectively resist the pressure during concrete pouring. When connecting the first and second formwork templates, the insertion shaft 503 and mounting plate 502 are moved manually via the mounting guide rail 501. When the mounting plate 502 reaches the apex of the mounting guide rail 501, the insertion shaft 503 extends into the square steel frame 3 of the other formwork. The insertion shaft 503 and the insertion limiting block 504 can be inserted into the elliptical insertion hole of the square steel frame 3. Rotating the insertion shaft 503 180 degrees causes the other two insertion shafts 503 to rotate simultaneously via the L-shaped rotating rod 506 and the synchronous connecting plate 507, facilitating installation and disassembly. The insertion shaft 503 can connect to the square steel frame of the other formwork via the insertion limiting block 504. 3. The anti-detachment block 505 will fit against one side of the steel frame 3 for limiting its position. Two locking plates 601 are then fitted onto the outside of the L-shaped rotating rod 506 and the synchronous connecting plate 507. The L-shaped rotating rod 506 then locks and fixes the three plug-in rotating shafts 503. The two locking plates 601 are fixed by plate bolts 602 and fixing nuts 603. When separating the first building template 1 and the second building template 2, the two locking plates 601... Retract the first bolt 605 by hand to fix the locking sleeve 601 through the mounting column 604 to prevent accidental pop-out. Then, when the mounting plate 502 is retracted through the mounting guide rail 501, the other end of the insertion shaft 503 is exactly on the same horizontal line as the limiting mechanism 7. Loosen the second bolt 704, move the mounting slide plate 702 and the L-shaped limiting plate 703 so that the L-shaped limiting plate 703 is embedded in one side of the L-shaped rotating rod 506, thereby limiting and fixing the insertion mechanism 5.
