Description

Technical Field

[0001] This utility model relates to the technical field of box girder formwork equipment, and in particular to a box girder formwork hole making device. Background Technology

[0002] In bridge construction, box girders are often prefabricated using box girder formwork to ensure the safety, quality, and efficiency of the construction.

[0003] During the prefabrication of box girders, many holes are typically required for subsequent construction stages. Therefore, the design of box girder formwork must include the locations of these holes and the consideration of sealing them to ensure proper concrete grouting during fabrication.

[0004] The existing devices for making holes in box girder formwork are mostly just a steel pipe or PVC pipe of the same size as the pre-reserved hole. This is inconvenient for construction workers to install, which can easily lead to errors. The subsequent disassembly process is also inconvenient, affecting the construction efficiency of box girder production. At the same time, such devices also have the problem of poor sealing, which can affect the effect of concrete grouting and thus affect the overall quality of the box girder. Utility Model Content

[0032] During the prefabrication of box girders, many holes are typically required for subsequent construction stages. Therefore, the design of box girder formwork must include the locations of these holes and the consideration of sealing them to ensure proper concrete grouting during fabrication.

[0033] The existing devices for making holes in box girder formwork are mostly just a steel pipe or PVC pipe of the same size as the pre-reserved hole. This is inconvenient for construction workers to install, which can easily lead to errors. The subsequent disassembly process is also inconvenient, affecting the construction efficiency of box girder production. At the same time, such devices also have the problem of poor sealing, which can affect the effect of concrete grouting and thus affect the overall quality of the box girder.

[0034] To address the aforementioned issues, this application provides a device for fabricating formwork holes for box girders, which ensures the accuracy of reserved holes after construction, effectively seals the reserved holes, and guarantees the overall production quality of the box girder.

[0035] See Figure 1-6 A box girder formwork hole making device is provided and installed at the reserved hole of the box girder formwork 3. The device includes: an installation cylinder assembly 1 and a hole forming pipe assembly 2.

[0036] Specifically, both the mounting cylinder assembly 1 and the perforated tube assembly 2 are made of steel. In this embodiment, the use of steel ensures the strength and durability of the manufacturing device.

[0037] The mounting sleeve assembly 1 includes: a mounting sleeve 101, a fixing plate 102, and a fixing bolt rod 103; the mounting sleeve 101 is installed at the reserved hole of the box girder template 3, and two sets of opposing mounting plates 1011 are provided on the side wall of the mounting sleeve 101, and a first mounting through hole 1012 is provided on the mounting plate 1011; specifically, the mounting sleeve 101 is fixed to the box girder template 3 by welding, and the hole diameter of the mounting sleeve 101 is set according to the size of the reserved hole.

[0038] The fixing plate 102 is an L-shaped plate. A fixing groove block 1021 is provided at one end of the fixing plate 102, and a second mounting through hole 1022 is provided at the other end of the fixing plate 102. The fixing plate 102 is hinged to a set of mounting plates 1011 by bolts passing through the first mounting through hole 1012 and the second mounting through hole 1022. One end of the fixing bolt rod 103 is provided with a third mounting through hole. The fixing bolt rod 103 is hinged to another set of mounting plates 1011 by bolts passing through the first mounting through hole 1012 and the third mounting through hole.

[0039] The perforated pipe assembly 2 includes: a perforated pipe 201 and a limiting plate 202, the limiting plate 202 being installed at the top end of the perforated pipe 201; the diameter of the perforated pipe 201 is slightly smaller than the diameter of the reserved hole.

[0040] The limiting plate 202 is a set of cross-shaped plates. The length of the limiting plate 202 is greater than the diameter of the mounting sleeve 101. A limiting notch 2021 is provided on the limiting plate 202 to limit the hole pipe 201 after it is placed into the mounting sleeve 101.

[0041] When in use, the perforated pipe 201 is installed in the installation sleeve 101 and is limited by the limiting insert plate 202. Then, by installing the fixing bolt rod 103 onto the fixing pressure plate 102, the fixing pressure plate 102 limits and fixes the perforated pipe assembly 2.

[0042] In this embodiment, by adjusting the installation angle of the installation sleeve 101, the perforated pipe assembly 2 can be easily installed, improving the accuracy of the installation and ensuring the accuracy of the reserved holes after construction. At the same time, after the perforated pipe 201 is installed in the installation sleeve 101, by rotating the fixing bolt rod 103 and the fixing pressure plate 102, the fixing bolt rod 103 is placed into the fixing groove block 1021 of the fixing pressure plate 102 and fixed by bolts. The fixing pressure plate 102 can limit and fix the limiting insert plate 202, preventing the perforated pipe assembly 2 from loosening and displacing during construction, achieving effective sealing of the reserved holes, ensuring the effect of concrete grouting, and ensuring the production quality of the overall box girder.

[0043] Specifically, the fixed pressure plate 102 is provided with a limiting groove block 1023 for limiting and fixing the limiting insert plate 202.

[0044] In this embodiment, by setting the limiting groove block 1023, the limiting insert plate 202 will be limited in the limiting groove block 1023, which enables the fixing plate 102 to better limit and fix the limiting insert plate 202.

[0045] Specifically, two fixing reinforcing plates 1013 are provided on the side wall of the mounting sleeve 101.

[0046] In this embodiment, the fixed reinforcing plate 1013 is fixed to the box girder template 3 by welding. By setting two fixed reinforcing plates 1013 on the side wall of the mounting sleeve 101, the structural strength and stability of the mounting sleeve 101 can be enhanced.

[0047] Specifically, the limiting plate 202 is provided with at least one handle through hole 2022.

[0048] In this embodiment, by providing a handle through hole 2022 on the limiting insert plate 202, construction personnel can more easily install and disassemble the limiting insert plate 202, thereby improving construction efficiency.

[0049] The technical solution in this application embodiment has the following beneficial effects: By adjusting the installation angle of the installation sleeve 101, this application embodiment can facilitate the installation of the perforated pipe assembly 2, improve the accuracy of installation, and ensure the accuracy of the reserved holes after construction; at the same time, after the perforated pipe 201 is installed in the installation sleeve 101, by rotating the fixing bolt rod 103 and the fixing pressure plate 102, the fixing bolt rod 103 is placed into the fixing groove block 1021 of the fixing pressure plate 102 and fixed by bolt installation. The fixing pressure plate 102 can limit and fix the limiting insert plate 202, prevent the perforated pipe assembly 2 from loosening and displacement during construction, achieve effective sealing of the reserved holes, ensure the effect of concrete grouting, and ensure the production quality of the overall box girder.
