[0020] The embodiment of the present utility model provides a positioning device for the corrugated pipe of a precast capping beam, as Figures 1-4As shown in the figure, it includes a steel pedestal 5, a positioning plate 1, a plurality of inner lining pipes 4, a plurality of corrugated pipes 2, and a plurality of fixing components 3; the plurality of fixing components 3 each include a base 31, an expansion sleeve 32, an elastic member 33, and an adjustment sleeve 34; one end of the base 31 is connected to the positioning plate 1, and the other end of the base 31 is connected to one end of the elastic member 33; the other end of the elastic member 33 is connected to one end of the adjustment sleeve 34, and the other end of the adjustment sleeve 34 abuts against the inner lining pipe 4; the expansion sleeve 32 is sleeved outside the base 31; the positioning plate 1 is connected to the steel pedestal 5; the plurality of corrugated pipes 2 are respectively sleeved outside the plurality of adjustment sleeves 34 and are respectively slidably connected to the plurality of adjustment sleeves 34; the plurality of corrugated pipes 2 are respectively sleeved outside the plurality of expansion sleeves 32; one ends of the plurality of corrugated pipes 2 all abut against the positioning plate 1, and the other ends of the plurality of corrugated pipes 2 are blocked; the inner lining pipe 4 is arranged inside the corrugated pipe 2, and the inner lining pipe 4 is configured to prevent the corrugated pipe 2 from deforming.
[0021] Exemplarily, the base 31 can be positioned through the positioning plate 1; when the adjustment sleeve 34 abuts against the inner lining pipe 4, under the action of manually pressing the inner lining pipe 4, the adjustment sleeve 34 moves towards the side close to the positioning plate 1, so that the elastic member 33 is compressed, reducing the distance between the adjustment sleeve 34 and the base 31, thereby achieving the purpose of adjusting the length during the installation of the inner lining pipe 4 and making it located inside the corrugated pipe 2 after installation; the expansion sleeve 32 cooperates with the inner wall of the corrugated pipe 2 to be able to position the corrugated pipe 2 in the radial direction, the positioning plate 1 can position the corrugated pipe 2 in the axial direction, and after the corrugated pipe 2 and the inner lining pipe 4 are installed, blocking the corrugated pipe 2 can prevent the inner lining pipe 4 from floating and also prevent concrete from entering the corrugated pipe 2 during pouring.
[0022] Exemplarily, the fixing component 3 adopts a modular design, which is convenient for installation, disassembly, and reuse.
[0023] Exemplarily, the elastic member 33 is made of a high-elastic material, such as spring steel or rubber elastomer, etc., and has good resilience and fatigue resistance. One end of the elastic member 33 is connected to the protruding part 312 of the base 31, and the other end is connected to the adjustment sleeve 34, and it adapts to inner lining pipes 4 of different sizes through its elastic deformation.
[0024] Exemplarily, the adjustment sleeve 34 is slidably connected to the corrugated pipe 2, and the inner lining pipe 4 abuts against the adjustment sleeve 34.
[0025] Exemplarily, the inner lining pipe 4 is made of a material compatible with the corrugated pipe 2. The inner lining pipe 4 can not only effectively prevent the corrugated pipe 2 from deforming due to extrusion during concrete pouring, but also enhance the overall strength and stability of the corrugated pipe 2.
[0026] In the embodiment of the present application, as Figures 1-4As shown, the base 31 includes a mounting portion 311 and a protrusion 312; one end of the mounting portion 311 is connected to the positioning plate 1, and the other end of the mounting portion 311 is connected to the protrusion 312; the elastic member 33 is sleeved outside the protrusion 312, one end of the elastic member 33 is connected to the mounting portion 311, and the other end of the elastic member 33 is connected to the adjusting sleeve 34; the expansion sleeve 32 is sleeved outside the mounting portion 311.
[0027] Exemplarily, one end of the mounting portion 311 is firmly connected to the positioning plate 1 by bolts or other fasteners to ensure the stability of the fixing assembly 3 in the horizontal direction. The protrusion 312 can provide support and connection points for the elastic member 33 and the adjusting sleeve 34.
[0028] In the embodiment of the present application, as Figures 1-4 shown, the adjusting sleeve 34 is provided with a groove 341; the elastic member 33 is disposed in the groove 341; the protrusion 312 is configured to cooperate with the protrusion 312.
[0029] Exemplarily, the groove 341 enables the elastic member 33 to be firmly embedded therein and cooperate with the protrusion 312, which helps to reduce the sliding and offset of the elastic member 33 during the force application process, thereby ensuring the overall stability of the fixing assembly 3 while realizing the adjustment function. Through the interaction between the elastic member 33 and the protrusion 312 via the groove 341, the elastic member 33 can generate a certain deformation when subjected to an external force, absorb and disperse the impact energy, and protect the corrugated pipe 2 from damage.
[0030] In the embodiment of the present application, as Figures 1-4 shown, the mounting portion 311 is provided with a first ventilation hole 313; the positioning plate 1 is provided with a second ventilation hole 11; the first ventilation hole 313 and the second ventilation hole 11 are coaxially arranged.
[0031] Exemplarily, when the inner liner 4 is installed, under the action of the manual pressing force on the inner liner 4, the adjusting sleeve 34 moves downward, which may cause the air between the adjusting sleeve 34 and the base 31 to not be discharged in time. If there is air inside the fixing assembly 3, there is a risk of the structure of the fixing assembly 3 failing.
[0032] In the embodiment of the present application, the material of the expansion sleeve 32 is nitrile rubber.
[0033] Exemplarily, nitrile rubber as the material of the expansion sleeve 32 has excellent oil resistance, wear resistance and certain elastic recovery ability. During the positioning process of the corrugated pipe 2, the expansion sleeve 32 made of nitrile rubber can effectively fix the corrugated pipe 2 and prevent the corrugated pipe 2 from shifting or being damaged due to external forces during the construction process.
[0034] Exemplarily, the adjusting sleeve 34 is made of polytetrafluoroethylene. Polytetrafluoroethylene has extremely high chemical stability, a low coefficient of friction, and excellent corrosion resistance. This enables the adjusting sleeve 34 to slide smoothly during adjustment, reducing frictional wear between the inner lining pipe 4 and the corrugated pipe 2. In addition, the high temperature resistance of polytetrafluoroethylene also ensures its stable performance in various construction environments.
[0035] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.
[0036] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limiting the present application; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present application.
