[0002] Bridge concrete steel formwork is a temporary structure specifically designed for bridge construction, used to form the shape and size required for concrete pouring.
[0003] Bridge steel formwork is a type of steel formwork specifically designed for constructing railway or highway bridges. It is widely used in construction projects and plays an important role in bridge construction due to its reusability and aesthetically pleasing concrete pouring. However, traditional installation methods rely solely on bolts for fastening during installation. This lack of support in the middle of the bolts and the fact that the bolts only provide positioning support can lead to limited connection strength and fixing direction, which is detrimental to the connection strength during installation and use.
[0004] Therefore, we provide a reusable concrete steel formwork for highway bridges. Utility Model Content
[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a reusable concrete steel formwork for highway bridges, thereby improving its connection strength.
[0006] In view of this, the present invention provides a reusable concrete steel formwork for highway bridges, comprising a steel formwork body and support blocks installed inside the side. The steel formwork body has several mounting holes through its opposite sides. The mounting holes are located between two adjacent support blocks, and a plug-in block is provided between two adjacent support blocks. The middle of the two support blocks between two adjacent plug-in blocks is hollow. A connecting cylinder is provided through the middle of the plug-in block, and a threaded hole with the same specifications as the mounting holes is provided through the middle of the connecting cylinder, and the threaded hole communicates with the interior of the mounting holes.
[0007] Preferably, a sliding strip is slidably provided on the side adjacent to the plug-in block of the support block. There are a plurality of sliding strips, and the sliding strips are symmetrically distributed on opposite sides of the plug-in block, with an even number of sliding strips on each side.
[0008] Preferably, a limiting plate is fixedly installed at one end of the sliding bar near the plug-in block, and the limiting plate is slidably connected with a guide groove, which is formed inside the plug-in block.
[0009] Preferably, the guide groove extends out of the outside of the plug-in block, and the sliding strip is inserted into the inside of the guide groove.
[0010] Preferably, a rotating plate is rotatably mounted on the end of the sliding bar away from the limiting plate, and the rotating plate is slidably connected to a slide rail, which is located inside the support block.
[0011] Preferably, the slide rail extends beyond the outside of the support block, and the sliding bar is inserted into the inside of the slide rail.
[0012] Preferably, the slide rail is L-shaped with an obtuse angle, and a horizontal guide plate is slidably disposed inside the horizontal part of the L-shape, the horizontal guide plate being installed on the side of the plug block.
[0013] Compared with the prior art, this utility model provides a reusable concrete steel formwork for highway bridges, which has the following advantages:
[0014] 1. This utility model provides a connecting cylinder between the mounting holes on both sides to provide a second fastening support for the middle part of the fastening component. This improves the tightness of the device connection while ensuring that the overall installation and disassembly of the device remain unchanged. Thus, it improves the installation connection strength while ensuring the ease of installation of the device.
[0015] 2. This utility model ensures the uniformity of the connection surface when the limiting plate contacts the side of the limiting plate inside the guide groove by setting the side of the limiting plate to the same degree of inclination as the side of the plug-in block, thus ensuring the connection strength of the sliding strip during tensile use.
[0016] 3. With the limiting plates and rotating plates on both sides of the sliding bar respectively connected and fixed, after the plug-in block is fixed, the sliding bar, support block and plug-in block are in a stable connection state, ensuring the strength of their use position.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] Example 1: A reusable steel formwork for highway bridge concrete, such as... Figures 1-6 As shown, it includes a steel mold body 1 and a support block 3 installed inside the side. The steel mold body 1 has several mounting holes 2 through its two sides. The mounting holes 2 are located between two adjacent support blocks 3, and a plug-in block 4 is provided between two adjacent support blocks 3. The middle of the two support blocks 3 between two adjacent plug-in blocks 4 is hollow. A connecting cylinder 5 is provided through the middle of the plug-in block 4. A threaded hole with the same specifications as the mounting hole 2 is provided through the middle of the connecting cylinder 5, and the threaded hole is connected to the inside of the mounting hole 2.
[0028] By using bolts or screws to fasten the components, allowing them to pass through the mounting holes 2 and the connecting cylinder 5 simultaneously, the steel mold body 1 is positioned in its place of use. Then, by releasing the bolts or screws, the positioning of the steel mold body 1 is released. The connecting cylinder 5, located between the mounting holes 2 on both sides, provides a second fastening support to the middle of the fastening components. This improves the tightness of the device connection while ensuring that the overall installation and disassembly of the device remain unchanged. Thus, while ensuring the ease of installation, the strength of the installation connection is also improved.
[0029] like Figures 1-6 As shown, a sliding strip 6 is slidably arranged on the side adjacent to the support block 3 and the plug-in block 4. There are several sliding strips 6, and the sliding strips 6 are symmetrically distributed on opposite sides of the plug-in block 4, and the number of sliding strips 6 on each side is an even number.
[0030] Guided by the even number of sliding bars 6 on both sides of the plug-in block 4, the uniformity of the plug-in block 4 when connected to the support blocks 3 on both sides is ensured, so that the force is more uniform and reliable, and the strength of the connection is guaranteed during use.
[0031] like Figures 1-6 As shown, a limiting plate 7 is fixedly installed at one end of the sliding bar 6 near the plug-in block 4. The limiting plate 7 is slidably connected to a guide groove 9, which is opened inside the plug-in block 4.
[0032] The guide groove 9 extends out of the outside of the plug block 4, and the sliding bar 6 is inserted into the inside of the guide groove 9.
[0033] First, by setting the side of the limiting plate 7 to be at the same angle as the side of the plug-in block 4, the uniformity of the connection surface is ensured when the limiting plate 7 contacts the side of the limiting plate 7 inside the guide groove 9, ensuring the connection strength of the sliding strip 6 during tensioning, and further improving the connection strength under the guidance of the sliding strip 6 on the connection between the plug-in blocks 4 and the support block 3 on both sides, ensuring the reliability and stability of the plug-in block 4 in use.
[0034] Example 2: A reusable concrete steel formwork for highway bridges, such as... Figures 1-6 As shown, a rotating plate 8 is rotatably mounted on the end of the sliding bar 6 away from the limiting plate 7. The rotating plate 8 is slidably connected to a slide rail 10, which is located inside the support block 3.
[0035] The slide rail 10 extends out of the outside of the support block 3, and the sliding bar 6 is inserted into the inside of the slide rail 10.
[0036] Under the positioning and guidance of the slide rail 10 on the rotating plate 8, and the rotation of the rotating plate 8 and the sliding bar 6, the sliding bar 6 is ensured to move in the correct direction inside the slide rail 10, and the rotating plate 8 and the inclined surface of the slide rail 10 can be stably fitted together, ensuring the uniformity and stability of their connection surface. Thus, with the respective connection and fixation of the limiting plates 7 on both sides of the sliding bar 6 and the rotating plate 8, after the plug-in block 4 is fixed, the sliding bar 6, the support block 3, and the plug-in block 4 are in a stable connection state, ensuring the strength of their use position.
[0037] like Figures 1-6 As shown, the slide rail 10 is L-shaped with an obtuse angle, and a horizontal guide plate 11 is slidably arranged inside the horizontal part of the L-shape. The horizontal guide plate 11 is installed on the side of the plug-in block 4.
[0038] With the horizontal guide plate 11 and the sliding bar 6 moving synchronously, the sliding bar 6 slides inside the slide rail 10 at the same time, so that the slide rail 10 and the sliding bar 6 form a positioning space again, thereby enabling the device to have the effect of being fastened in the vertical direction at the same time, ensuring the strength of the device during installation and use, and setting the remaining connecting parts to follow the movement of the plug-in block 4, automatically limiting the connection, ensuring the convenience and safety of the device in use.
[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
