Description

Technical Field

[0001] This utility model relates to the field of U-shaped beam formwork technology, specifically to a U-shaped beam formwork with high toughness and high rigidity. Background Technology

[0002] U-shaped beam formwork is a construction mold specifically designed for precast U-shaped beams. It consists of a bottom mold, inner and outer molds, and end molds, and its opening and closing are controlled by a hydraulic or mechanical system. Its unique asymmetrical U-shaped structure effectively reduces bridge construction height and improves space utilization, making it suitable for scenarios such as elevated rail transit bridges. The formwork system is characterized by convenient movement, efficient installation and dismantling, and precise forming. Combined with high-performance concrete and advanced vibration compaction technology, it ensures the quality of the beam. With increasing infrastructure investment and technological innovation, the market demand for U-shaped beam formwork continues to grow, with environmental friendliness and lightweight design becoming the development trends.

[0003] Chinese patent CN221496515U discloses a U-shaped beam formwork, including a support and a formwork. The formwork includes an outer mold and an inner mold. The outer mold is fixed on the support, and the inner mold is located on the side of the outer mold away from the support. The inner mold is U-shaped and has a counterweight. The counterweight and the support are detachably connected by a first tie rod. By using the first tie rod, the inner mold can be quickly replaced according to different pouring requirements without having to disassemble other parts multiple times, simplifying the entire replacement process. This makes the connection and disassembly of the formwork with the support more convenient and efficient, reducing manual labor intensity and improving construction efficiency.

[0004] The U-shaped beam formwork described in the aforementioned patent document allows for quick replacement of the inner mold according to different pouring requirements, solving the problem of repeated disassembly and replacement of the inner mold and reducing manual labor intensity. However, the inner membrane of the aforementioned U-shaped beam formwork has a large volume, making it impossible to fold and store it. Therefore, a U-shaped beam formwork with high toughness and high rigidity is proposed. Utility Model Content

[0005] To address the aforementioned issues, a U-shaped beam formwork with high toughness and rigidity is provided. A second hydraulic telescopic component moves the folding plate, causing one side of the folding plate to gradually approach the side panel. At this point, the folding plate and the side panel gradually become parallel, thus achieving the folding of the plate. The first hydraulic telescopic component moves the side panel, causing it to gradually become parallel to the lower end face of the floating frame. This enables the inner formwork to fold, solving the problem of the large size and inconvenient storage of the U-shaped beam formwork.

[0006] To address the existing technical problems, this application provides a U-shaped beam formwork with high toughness and high rigidity, including two sets of outer formwork, a floating frame set on top of the two sets of outer formwork, and an inner formwork set at the bottom of the floating frame. The inner formwork includes a side plate, the top of which is hinged to the lower end face of the floating frame, and a folding plate is hinged to the bottom of the side plate.

[0007] A boss is provided at the center of the lower end face of the floating frame. Several first hydraulic telescopic components are provided at equal intervals on both sides of the boss. One end of the first hydraulic telescopic component is hinged to the boss, and the output end of the first hydraulic telescopic component is hinged to one side of the side plate.

[0008] A second hydraulic telescopic component is hinged to one side of the side plate, and the output end of the second hydraulic telescopic component is hinged to one side of the folding plate.

[0009] As one technical solution of this application, several positioning rods are fixed at equal intervals on the top of the two sets of outer templates;

[0010] The floating frame has a positioning hole near its edge that can penetrate its upper and lower surfaces, and the positioning hole is adapted to the positioning rod.

[0011] As one technical solution of this application, a support component for supporting the outer template is provided on the outer side surface of the outer template. The support component includes a sleeve, and a threaded rod that can move along its central axis is installed on the top of the sleeve. One end of the threaded rod is hinged to the outer side surface of the outer template.

[0012] As one technical solution of this application, a rotating component capable of rotating around its central axis is installed on the top of the sleeve. The rotating component is fitted outside the threaded rod, and the rotating component is threadedly connected to the threaded rod.

[0013] As one technical solution of this application, the bottom of the two sets of outer templates is hinged with a base plate that can be flipped.

[0014] A filling plate is provided between the two sets of outer templates, and the two sides of the filling plate are fixedly connected to the base plate respectively.

[0015] As one technical solution of this application, the upper end face of the floating frame is symmetrically fixed with a lifting lug connected to the hook.

[0016] As one technical solution of this application, the floating frame has filling ports for filling aggregate on both sides near the positioning holes.

[0017] As one technical solution of this application, a storage groove for storing the base plate is provided at the bottom of the outer side wall of the outer template.

[0018] The advantages of this utility model compared to the prior art are:

[0019] This application uses a second hydraulic telescopic component to move the folding plate, causing one side of the folding plate to gradually approach the side of the side plate. At this point, the folding plate and the side plate gradually become parallel, thus achieving the folding of the plate. The first hydraulic telescopic component moves the side plate, causing it to gradually become parallel to the lower end face of the floating frame. This enables the inner formwork to fold, solving the problem of the large volume and inconvenience of storing U-shaped beam formwork. Attached Figure Description

[0027] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0028] See Figures 1-6 As shown, a U-shaped beam formwork with high toughness and high rigidity includes two sets of outer formwork 1, a floating frame 6 set on top of the two sets of outer formwork 1, and an inner formwork 5 set on the bottom of the floating frame 6, including a side plate 51. The top of the side plate 51 is hinged to the lower end face of the floating frame 6, and a folding plate 52 is hinged to the bottom of the side plate 51.

[0029] A boss 60 is provided at the center of the lower end face of the floating frame 6. Several first hydraulic telescopic members 7 are provided at equal intervals on both sides of the boss 60. One end of the first hydraulic telescopic member 7 is hinged to the boss 60, and the output end of the first hydraulic telescopic member 7 is hinged to one side of the side plate 51.

[0030] A second hydraulic telescopic member 8 is hinged to one side of the side plate 51, and the output end of the second hydraulic telescopic member 8 is hinged to one side of the folding plate 52.

[0031] When folding the inner formwork 5, firstly, the second hydraulic telescopic component 8 is activated, causing its output end to retract. This moves the folding plate 52, gradually bringing one side of the folding plate 52 closer to the side plate 51. The folding plate 52 and side plate 51 then gradually become parallel, allowing the folding plate 52 to fold up. Then, the first hydraulic telescopic component 7 is activated, causing its output end to retract. This moves the side plate 51, gradually aligning it with the lower surface of the floating frame 6. This allows the inner formwork 5 to fold, solving the problem of the large size and inconvenient storage of the U-shaped beam formwork.

[0032] See Figure 1 , Figure 4 and Figure 5 As shown, several positioning rods 11 are fixed at equal intervals on the top of the two sets of outer templates 1;

[0033] The floating frame 6 has a positioning hole 63 near its edge that can penetrate its upper and lower surfaces. The positioning hole 63 is adapted to the positioning rod 11.

[0034] To ensure the stability of the floating frame 6, a positioning hole 63 is opened at the edge of the floating frame 6, so that the positioning rod 11 at the top of the outer template 1 can be inserted into the positioning hole 63. This allows the positioning rod 11 and the positioning hole 63 to cooperate with each other, effectively preventing the floating frame 6 from shifting.

[0035] See Figure 1 , Figure 3 , Figure 4 and Figure 6 As shown, a support assembly 2 for supporting the outer template 1 is provided on the outer side surface. The support assembly 2 includes a sleeve 22. A threaded rod 21 that can move along its central axis is installed on the top of the sleeve 22. One end of the threaded rod 21 is hinged to the outer side surface of the outer template 1.

[0036] By installing the threaded rod 21 inside the sleeve 22, the threaded rod 21 can move along the central axis of the sleeve 22, thereby allowing the overall length of the support assembly 2 to be adjusted. By hinged one end of the threaded rod 21 to the outer side of the outer template 1, the threaded rod 21 and the sleeve 22 cooperate to support the outer template 1, thereby improving the load-bearing strength of the outer template 1.

[0037] See Figure 6 As shown, a rotating component 23 capable of rotating around its central axis is installed on the top of the sleeve 22. The rotating component 23 is fitted outside the threaded rod 21 and is threadedly connected to the threaded rod 21.

[0038] When the rotating component 23 is rotated, the rotating component 23 can drive the threaded rod 21 connected to it to move along the central axis of the sleeve 22, so that the overall length of the support component 2 can be adjusted, thereby making the support component 2 adaptable to a wider range.

[0039] See Figure 2 and Figure 4 As shown, the bottom of the two sets of outer templates 1 are hinged to a base plate 3 that can be flipped.

[0040] A filling plate 4 is provided between the two sets of outer templates 1, and the two sides of the filling plate 4 are fixedly connected to the base plate 3 respectively.

[0041] By fixing the two sides of the filling plate 4 to the base plate 3 respectively, the outer template 1, the base plate 3 and the filling plate 4 are matched with each other to shape the U-shaped beam, effectively ensuring the shape of the U-shaped beam.

[0042] See Figure 1 , Figure 3 and Figure 4 As shown, the upper end face of the floating frame 6 is symmetrically fixed with a lifting lug 61 that is connected to the hook.

[0043] To facilitate the hoisting of the floating frame 6, multiple lifting lugs 61 are symmetrically installed on the upper surface of the floating frame 6. This allows the hook to be hooked onto the lifting lugs 61, thus facilitating the hoisting operation of the floating frame 6.

[0044] See Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, the floating frame 6 has filling ports 62 for filling aggregate on both sides near the positioning holes 63.

[0045] To facilitate the filling of aggregate into the U-shaped beam formwork, filling ports 62 are opened on both sides of the floating frame 6, allowing the aggregate to be filled into the U-shaped beam formwork through the filling ports 62.

[0046] See Figure 4As shown, a storage groove 12 for storing the base plate 3 is provided at the bottom of the outer side wall of the outer template 1.

[0047] By opening a storage groove 12 on the outer side wall at the bottom of the outer template 1, the base plate 3 can be placed inside the storage groove 12 when folded, making the storage of the base plate 3 more convenient.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
