Description

Technical Field

[0001] This utility model belongs to the technical field of base for precast piers, specifically relating to a positioning and casting base for precast piers that does not require roughening. Background Technology

[0002] Currently, my country's road and bridge construction is developing rapidly, and the most common method for constructing piers in the past was on-site casting. With continuous urban development, the use of on-site casting for pier construction in urban areas is increasingly constrained by surrounding environmental requirements and construction conditions. Therefore, the fully prefabricated production model of pier components in factories is being used more and more widely, and factory prefabrication of piers is a construction method that is becoming increasingly popular. During pier prefabrication, appropriate bases need to be set up on-site to place and fix the prefabricated piers. At the same time, to ensure the verticality and stability of the prefabricated piers, the top surface of the base must be level and the base must be fixed within the prefabrication site. Exposed reinforcing bars of the prefabricated piers need to be protected, and the bottom of the piers must be roughened after casting. Therefore, the functional requirements of the base are more comprehensive. Thus, a base design is needed to solve the above problems. Utility Model Content

[0021] Please see Figures 1-2 This embodiment proposes a precast pier column positioning and casting base without roughening, including a top plate 1 and a bottom plate 2 arranged in parallel. In this embodiment, to ensure the strength of the base, both the top plate 1 and the bottom plate 2 are made of steel. The top plate 1 and the bottom plate 2 are connected by connecting vertical plates 3; the ends of the connecting vertical plates 3 are connected to form a circumferential structure, the top of the connecting vertical plates 3 is connected to the top plate 1, and the bottom of the connecting vertical plates 3 is connected to the bottom plate 2; the top plate 1 is provided with a roughening-free grout-stopping strip 4, which provides sufficient roughness to the bottom surface of the pier column; the roughening-free grout-stopping strip 4 has several steel bar connection holes 6 on its outer circumference.

[0022] A steel plate 5 is connected to the top slab 1. Steel plate 5 has rebar connection holes 6 along its edge, which penetrate both the steel plate 5 and the top slab 1. A non-scraping grout-stopping strip 4 is attached to the top of the steel plate 5. The bottom rebar of the precast pier can pass through the rebar connection holes 6 to achieve positioning connection with the base. Several rebar protection pipes 7 are connected between the top slab 1 and the bottom slab 2. The rebar protection pipes 7 are concentrically arranged with the rebar connection holes 6, allowing the rebar passing through the rebar connection holes 6 to directly enter the rebar protection pipes 7. This structure ensures that the exposed rebar is protected during mold closing, turning, and pouring of the precast pier, and also serves to position the rebar.

[0023] A reinforcing rib plate 8 is also provided between adjacent reinforcing steel protective pipes 7; the top of the reinforcing rib plate 8 is connected to the top plate 1, the bottom is connected to the bottom plate 2, and the inner side is connected to the vertical plate 3, so as to support the top plate 1 and the bottom plate 2.

[0024] In addition, several upper bolt fixing holes 9 are opened along the upper edge of the top plate 1. The bottom of the precast pier column is connected to the top plate 1 by bolts, which are fixed by passing through the upper bolt fixing holes 9. Several lower bolt fixing holes 10 are opened along the upper edge of the bottom plate 2. The positioning and casting base of the precast pier column is fixed to the ground by passing through the lower bolt fixing holes 10.

[0025] In this embodiment, the four corners of the top plate 1 and the bottom plate 2 are rounded 11 to prevent bumps and collisions during construction. This can prevent personnel from being injured during construction and also prevent the corners from being damaged during transportation.

[0026] In use, the exposed reinforcing bars of the precast pier are inserted into the reinforcing bar protection pipe 7 through the reinforcing bar connection hole 6. The side formwork of the precast pier is then securely connected to the top plate 1 by bolts passing through the upper bolt fixing holes 9. The base is fixed through the evenly distributed lower bolt fixing holes 10 on the bottom plate 2. This not only allows for precise positioning of the precast pier reinforcing bars but also ensures the safety and stability of the pier during casting. The no-scraping grout-stopping strip 4 is made of PVC and has a mesh shape. During the precast pier process, the no-scraping grout-stopping strip 4 provides sufficient roughness to the bottom surface of the pier, achieving a no-scraping effect.

[0027] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
