Technical Field
[0001] This utility model relates to the field of cast-in-place beam technology, and in particular to a side formwork device for cast-in-place beams. Background Art
[0002] Currently, the steel side formwork used in cast-in-place bridge construction in China is mostly single-piece assembled formwork. When the construction of the next span is carried out after the completion of one span, the single formwork needs to be disassembled, assembled, and transported. Cranes and transport vehicles need to wait for a long time to coordinate, which consumes a lot of machine shifts and has low efficiency. Especially when there are municipal roads under the bridge, it will also obstruct the passage of social vehicles, resulting in a long construction cycle for each span of cast-in-place bridge, high safety risks in hoisting operations, and significant impact on traffic.
[0003] Patent No. ZL202021682394.0 discloses a mobile cast-in-place beam side formwork device. The surface of the working plate is similar in shape to the side of the cast-in-place beam. The end of the working plate farther from the cast-in-place beam extends upward and has mating holes at a height higher than the beam surface towards the cast-in-place beam. A support truss is set at the bottom of the working plate to support the working plate, and the bottom of the support truss is equipped with traveling wheels and an adjustable top support. After the support frame and channel steel rail are erected, the formwork is manually pushed to the predetermined position in sequence, so that adjacent formwork pieces are closely brought together, and wooden wedges are inserted under the traveling wheels for fixation. After the formwork is in place, bolts are passed through the two outer reinforcing ribs on the back of the working plate to connect the formwork system into one unit. However, in the above-mentioned patent, when splicing multiple sets of side formwork devices, the relative positions between adjacent side formwork devices are not easily aligned, and the use of bolts and other fasteners results in low installation efficiency.

DETAILED DESCRIPTION
[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0029] Reference Figures 1 to 7 One embodiment provided by this utility model:
[0030] A side formwork device for cast-in-place beams includes a template 3 that matches the shape of the side of the cast-in-place beam, a fixed frame 4 located below the template 3, movable wheels 5 rotatably connected to the fixed frame 4, and support feet 6 that are lifted and lowered below the fixed frame 4. It also includes a guide mechanism for positioning adjacent fixed frames 4 and a locking mechanism for securing adjacent templates 3. The guide mechanism includes guide grooves 7 and guide rails 8 respectively located on both sides of the fixed frame 4. The guide grooves 7 and guide rails 8 are rotatably connected to the fixed frame 4 and extend outwards relative to the fixed frame 4. The guide rails 8 are inserted into the guide grooves 7 and slidably connected to the guide grooves 7. The locking mechanism includes hooks 9 and lugs 10 located on both sides of the back of the template 3. The hooks 9 are rotatably connected to the template 3 and swing outwards relative to the template 3. The lugs 10 are matched with the hooks 9 and are movably engaged with the hooks 9.
[0031] Template 3, fixing frame 4, casters 5, and support legs 6 are installed sequentially from top to bottom. Template 3 is inclined to match the shape of the side of the cast-in-place beam and is used for concrete pouring, serving as a forming component. Fixing frame 4 is located below template 3, installed vertically, and connected to the back of template 3, serving as the main component. Casters 5 are located below fixing frame 4, using a universal wheel structure, and are rotatably connected to the bottom of fixing frame 4, serving as a moving component. Support legs 6 are located below fixing frame 4, using an electrically telescopic structure, and are raised and lowered to the bottom of fixing frame 4, serving as a supporting component. When support legs 6 extend downwards, they can lift fixing frame 4, causing casters 5 to leave the ground and achieve stable placement.
[0032] When assembling side formwork for cast-in-place beams, multiple side formwork devices are assembled according to the dimensions of the cast-in-place beams. Adjacent side formwork devices are connected by guiding and locking mechanisms to form a single unit. For ease of understanding, the sequentially assembled side formwork devices can be defined as the first side formwork device 1, the second side formwork device 2, the third side formwork device, the fourth side formwork device, etc., with the first side formwork device 1 serving as the assembly positioning reference. In the following embodiments, the first side formwork device 1 and the second side formwork device 2 are used as examples to explain the assembly process of positioning adjacent fixing frames 4 and fastening adjacent templates 3.
[0033] The guiding mechanism positions adjacent fixed frames 4. Guide grooves 7 and guide rails 8 are located on both sides of the fixed frames 4, corresponding and flush with each other. Guide grooves 7 and guide rails 8 are rotatably connected to the fixed frames 4, arranged in a vertically flipping configuration, unfolding relative to the outside of the fixed frames 4. Guide grooves 7 and guide rails 8 between adjacent fixed frames 4 are interlocked. Alternatively, guide rail 8 can be located on the left side of the fixed frame 4, rotating relative to the left side of the fixed frame 4 from a vertical position to a horizontal position extending to the left; guide groove 7 can be located on the right side of the fixed frame 4, rotating relative to the right side of the fixed frame 4 from a vertical position to a horizontal position extending to the right. When assembly is required, guide grooves 7 and guide rails 8 are first unfolded outwards. The guide groove 7 of the first cast-in-place beam side formwork device 1 is coaxially aligned with the guide rail 8 of the second cast-in-place beam side formwork device 2. The second cast-in-place beam side formwork device 2 is then pushed, causing the guide rail 8 to be inserted into the guide groove 7 and slide along the guide groove 7 to its end, thus positioning the adjacent fixed frames 4.
[0034] The locking mechanism secures adjacent templates 3. Hooks 9 and lugs 10 are located on both sides of the back of template 3, corresponding and flush with each other. Hooks 9 are rotatably connected to template 3 and swing relative to the outside of template 3. Lugs 10 are fixedly connected to template 3 and matched with hooks 9. Hooks 9 and lugs 10 between adjacent templates 3 engage with each other. Alternatively, hooks 9 can be located on the left side of template 3, and lugs 10 on the right side. Hooks 9 swing relative to the left side of the fixing frame 4 and engage with the lugs 10 of adjacent templates 3. When assembly is required, the guide groove 7 of the first cast-in-place beam side formwork device 1 is inserted into the guide rail 8 of the second cast-in-place beam side formwork device 2 to position adjacent fixing frames 4. At this time, the adjacent templates 3 are aligned. Then, hooks 9 of the second cast-in-place beam side formwork device 2 are swung outwards until they align with the lugs 10 of the first cast-in-place beam side formwork device 1, thus securing the adjacent templates 3.
[0035] This utility model, by setting up a guiding mechanism and a locking mechanism, uses guide grooves 7 and guide rails 8 for guidance and hooks 9 and lugs 10 for fastening. When assembling multiple cast-in-place beam side formwork devices, the positions are easy to align, the operation is more convenient, and the installation efficiency is effectively improved. First, move the first cast-in-place beam side formwork device 1 to a predetermined position as the assembly positioning benchmark. The guide groove 7 and guide rail 8 are unfolded relative to the outside of the fixed frame 4. Then, align the guide rail 8 of the second cast-in-place beam side formwork device with the guide groove 7 of the first cast-in-place beam side formwork device 1. Insert the guide rail 8 into the guide groove 7 and slide it along the guide groove 7 to the end to complete the positioning of the adjacent fixed frame 4. Next, swing the hook 9 of the second cast-in-place beam side formwork device to engage with the hanging ear 10 of the first cast-in-place beam side formwork device 1. After multiple sets of hooks 9 and hanging ears 10 engage with each other, the adjacent formwork 3 is fastened. Repeat the above steps to assemble multiple cast-in-place beam side formworks in sequence to connect them into one unit. Then, adjust the height of the support legs 6 uniformly to ensure the same installation height, and the subsequent concrete pouring process can be carried out.
[0036] In this embodiment, preferably, the fixing frame 4 is provided with L-shaped fixing shoulders on both sides, the fixing shoulders are arranged facing outwards, the guide groove 7 and the guide rail 8 are rotatably connected in the fixing shoulders and horizontally abut against the end face of the fixing shoulders.
[0037] The fixed shoulders are located on both sides of the fixed frame 4, and have an L-shaped structure with the opening facing outwards. The guide grooves 7 and guide rails 8 are located inside the fixed shoulders and are rotatably connected to them. In the normal state, the guide grooves 7 and guide rails 8 are vertically set and abut against the side wall of the fixed shoulders, hidden and stored on both sides of the fixed frame 4. When needed, the guide grooves 7 and guide rails 8 unfold outwards and become horizontally set, abutting against the end face of the fixed shoulders. The fixed shoulders act as a limiter, ensuring that the guide grooves 7 and guide rails 8 of adjacent fixed frames 4 remain on the same plane, facilitating insertion and installation.
[0038] In this embodiment, preferably, the guide groove 7 has a U-shaped structure, including a sliding groove 11 that runs through the front and back, and a slide 12 located outside the sliding groove 11. One side of the slide 12 is connected to the sliding groove 11, and the other side of the slide 12 is connected to the outside.
[0039] The guide groove 7 has a U-shaped structure. The slide rail 12 is located in the middle of the guide groove 7 and is arranged to run through the front and back. The slide rail 12 is located outside the slide groove 11 and is arranged along the direction of the slide rail 12. One side of the slide rail 12 is connected to the slide groove 11, and the other side of the slide rail 12 is connected to the outside. The slide rail 12 and the slide groove 11 form a T-shaped groove structure, which is inserted and slidably connected to the guide rail 8. At the same time, it limits the horizontal movement of the guide rail 8 to prevent the guide rail 8 from moving laterally and improve the guiding accuracy.
[0040] In this embodiment, preferably, the guide rail 8 has a T-shaped structure, including a guide block 13 that matches the slide groove 11 and a guide plate 14 that matches the slide rail 12. The guide block 13 is slidably connected to the slide groove 11, and the guide plate 14 is slidably connected to the slide rail 12.
[0041] The guide rail 8 has a T-shaped structure. The guide block 13 is positioned relative to the outer side of the guide rail 8 and matches the shape of the slide groove 11. The guide plate 14 is positioned relative to the inner side of the guide rail 8 and matches the shape of the slide rail 12. A rotatable roller may be provided below the guide block 13. The guide block 13 is inserted into the slide groove 11, and the roller rolls against the bottom of the slide groove 11, reducing the sliding friction between the guide block 13 and the slide groove 11 and improving the smoothness of movement. When adjacent fixed frames 4 are positioned, the guide groove 7 of the first cast-in-place beam side formwork device 1 is coaxially aligned with the guide rail 8 of the second cast-in-place beam side formwork device 2, so that the guide block 13 is aligned front-to-back with the slide groove 11, and the guide plate 14 is aligned front-to-back with the slide rail 12. This pushes the second cast-in-place beam side formwork device 2, causing the guide block 13 to engage with the slide groove 11 and slide along the direction of the slide groove 11, and the guide plate 14 to engage with the slide rail 12 and slide along the direction of the slide rail 12, improving installation stability.
[0042] In this embodiment, preferably, the fixing frame 4 is provided with limiting blocks 15 on both sides, with one limiting block 15 being set relative to the end of the guide groove 7 and the other limiting block 15 being set relative to the beginning of the guide rail 8.
[0043] The limiting blocks 15 are located on both sides of the fixing frame 4 and can be divided into a first limiting block 15 and a second limiting block 15. The first limiting block 15 is located at the end of the guide groove 7. After the guide groove 7 is rotated to a horizontal position, the guide groove 7 and the first limiting block 15 are aligned. The second limiting block 15 is located at the beginning of the guide rail 8. After the guide rail 8 is rotated to a horizontal position, the guide rail 8 and the second limiting block 15 are aligned. When assembly is required, the guide groove 7 of the first cast-in-place beam side formwork device 1 and the guide rail 8 of the second cast-in-place beam side formwork device 2 are coaxially aligned. The second cast-in-place beam side formwork device 2 is pushed so that the guide rail 8 is inserted into the guide groove 7 and slides along the guide groove 7 to the end until the first limiting block 15 abuts against the end of the guide rail 8 and the second limiting block 15 abuts against the beginning of the guide groove 7, thus limiting the sliding stroke of the guide rail 8 and improving the installation accuracy.
[0044] In this embodiment, preferably, the back of the template 3 is provided with a seat plate 16 for the hook 9 to be movably installed. The seat plate 16 has a through waist-shaped groove 17 in the middle.
