Description

Technical Field

[0001] The utility model relates to the technical field of bridge pier formwork, in particular to an assembled bridge prefabricated pier formwork. Background Art

[0002] Pier formwork is mainly used in highway bridges and highway bridge projects. It is a fixed formwork for pouring bridge concrete columns. The shape of the pier formwork is mainly circular, and its sizes vary. The pier formwork adopts a cast-in-place construction process. A set of formwork consists of two semicircular formworks, which are assembled with screws. This style not only facilitates the installation and disassembly of the formwork, but also effectively avoids and reduces the pressure of transportation. Therefore, an assembled bridge prefabricated pier formwork will be used.

[0003] The existing prefabricated pier formwork for assembled bridges is difficult to seal, which leads to the easy leakage of concrete during pouring, making it less suitable for use. Utility Model Content

[0004] The purpose of the utility model is to provide an assembled bridge prefabricated pier template to solve the defect that the existing assembled bridge prefabricated pier template is inconvenient to seal.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an assembled bridge prefabricated pier template, comprising a template assembly and a pier assembly;

[0006] The formwork assembly includes a positioning seat, a first formwork, a second formwork, and fixing bolts. A pier assembly is provided on the top of the positioning seat. The first formwork is provided on the top of the positioning seat on one side of the pier assembly, and the second formwork is provided on the top of the positioning seat on the other side of the pier assembly. Fixing bolts are evenly passed through both sides of the first and second formworks.

[0007] The outer sides of the first template and the second template are both provided with a reinforcement structure, and one side of the bottom of the first template and the second template is fixed with a mounting structure;

[0008] Sealing structures are provided on both sides of the interior of the first template, and the sealing structures include limiting grooves, rubber plates, sealing strips and cavities. The limiting grooves are provided on both sides of the interior of the first template, and rubber plates are provided inside the limiting grooves. One end of the rubber plates extends to the outside of the first template and is fixed with a sealing strip, and a cavity is provided inside the sealing strip.

[0009] When using the device, by providing a sealing structure, the device can be easily sealed, thereby improving the applicability of the prefabricated bridge pier template of the assembled bridge during use; by providing a reinforcing structure, the device can be easily reinforced, thereby improving the service life of the prefabricated bridge pier template of the assembled bridge during use; by providing an installation structure, the device can be easily fixed, thereby improving the stability of the prefabricated bridge pier template of the assembled bridge during use.

[0010] Preferably, the reinforcement structure includes a first reinforcement plate, a second reinforcement plate, and a support plate. The support plates are evenly fixed to the outsides of the first and second templates. The first reinforcement plate is fixed to one side of the interior of the support plates, and the second reinforcement plate is fixed to the other side of the interior of the support plates. The first and second reinforcement plates are fixed to the outsides of the first and second templates, and the strength and load-bearing capacity of the first and second templates are enhanced under the action of the first and second reinforcement plates.

[0011] Preferably, the first reinforcing plate is fixedly connected to the outer walls of the first and second templates on a side remote from the support plate, and the second reinforcing plate is fixedly connected to the outer walls of the first and second templates on a side remote from the support plate. The support plate has an arc-shaped cross-section when viewed from above. The support plate enhances the compressive and bending resistance of the first and second templates, preventing deformation or damage during use.

[0012] Preferably, the mounting structure includes a mounting plate, mounting holes, and reinforcing ribs. The mounting plate is fixed to one side of the bottom of the first and second templates. The mounting holes are evenly distributed inside the mounting plate, and reinforcing ribs are fixed to the top of the mounting plate on both sides of the mounting holes. When the first template is moved, the first template drives the mounting plate to the outside of the pier assembly at the top of the positioning seat. The mounting plate is fixed to the top of the positioning seat through the mounting holes, thereby enhancing stability during use.

[0013] Preferably, the mounting holes are evenly spaced within the mounting plate, and the reinforcing ribs are fixedly connected to the outer walls of the first and second templates on a side away from the mounting plate. The reinforcing ribs enhance the load-bearing area between the mounting plate and the first template, thereby improving its load-bearing capacity.

[0014] Preferably, the pier assembly includes a base, a positioning groove, a positioning column, steel bars and stirrups. The base is arranged at the top of the positioning seat, a positioning groove is provided at the bottom of the base, a positioning column is provided inside the positioning groove, steel bars are evenly fixed on the top of the base, and stirrups are evenly fixed on the outside of the steel bars.

[0016] Preferably, the rubber sheet and the first formwork form a sliding structure via a limiting groove, wherein the limiting groove has a T-shaped cross-section when viewed from above. When the rubber sheet is moved into the limiting groove and the second formwork and the first formwork are fixed to each other using fixing bolts, the sealing strip deforms under the action of the cavity, and the outer side of the sealing strip then fits against the inner sides of the first and second formworks, thereby enhancing the sealing between the first and second formworks and preventing concrete leakage from the connection between the first and second formworks during pouring.

[0017] The utility model provides an assembled bridge prefabricated pier template, which has the following advantages:

[0018] By providing a sealing structure, the rubber plate is moved to the inside of the limiting groove, and when the second template and the first template are fixed to each other by fixing bolts, the sealing strip is deformed under the action of the cavity. At this time, the outer side of the sealing strip is in contact with the inner side of the first template and the second template, thereby improving the sealing between the first template and the second template, preventing concrete from leaking from the connection between the first template and the second template during pouring, realizing the sealing function of the device, and thus improving the applicability of the prefabricated bridge pier template during use;

[0019] By providing a reinforcement structure, the first and second reinforcement plates are fixed to the outsides of the first and second templates. Under the action of the first and second reinforcement plates, the strength and bearing capacity of the first and second templates are enhanced. Under the action of the support plate, the compressive and bending resistance of the first and second templates are enhanced, preventing the first and second templates from being deformed or damaged during use. The device realizes the function of facilitating reinforcement, thereby increasing the service life of the prefabricated bridge pier template of the assembled bridge.

[0020] By providing an installation structure, the first template is moved, and the first template drives the installation plate to move to the outside of the pier assembly at the top of the positioning seat, and the installation plate is fixed to the top of the positioning seat through the installation hole, thereby enhancing the stability during use. Under the action of the reinforcing ribs, the force area between the installation plate and the first template is enhanced, and its bearing capacity is improved, thereby realizing the function of facilitating fixation of the device, thereby improving the stability of the prefabricated pier template of the assembled bridge during use.
