Description

Technical Field

[0001] This utility model relates to the field of building material production technology, specifically a reinforced concrete column casting mold. Background Technology

[0002] As the core load-bearing component of a building structure, the construction quality of reinforced concrete columns directly affects the overall safety and durability of the project. Existing molds are mostly designed with fixed cross-sections, which cannot adapt to the construction needs of concrete columns of different specifications. Frequent mold changes or on-site modifications are required during construction, leading to material waste and project delays. Traditional mold joints lack adequate sealing measures (such as using only wooden formwork splicing), allowing concrete to easily seep through the gaps during pouring, resulting in surface defects such as pitting and voids. Utility Model Content

[0003] The purpose of this utility model is to provide a reinforced concrete column casting mold that enables stepless adjustment of the casting section thickness, thereby reducing the types of molds and construction costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A reinforced concrete column casting mold, characterized in that it includes a casting bottom mold, an opening on the upper side of the casting bottom mold, a top mold slidably disposed at the opening, a casting port at one end of the casting bottom mold, an adjusting plate slidably disposed at the bottom inner side of the casting bottom mold, a screw rod uniformly rotatably disposed at the bottom of the adjusting plate, the outer end of the screw rod passing through the bottom of the casting bottom mold and extending below the casting bottom mold, a handle fixedly disposed at the outer end of the screw rod, a threaded sleeve fixedly disposed at the connection between the lower side of the casting bottom mold and the screw rod, the screw rod and the threaded sleeve cooperating, and an exhaust hole provided on the top mold.

[0006] In a preferred embodiment, handrails are fixedly installed at both ends of the casting bottom mold.

[0007] In a preferred embodiment, the casting bottom mold includes a U-shaped end plate, with end plates fixedly installed at both ends of the end plate, and the casting port is located on the end plate.

[0008] In a preferred embodiment, reinforcing ribs are welded between the outer side of the end plate and the surrounding plate.

[0009] In a preferred embodiment, the outer side of the enclosure is provided with multiple U-shaped reinforcing plates.

[0010] In a preferred embodiment, a positioning pin is provided between the threaded sleeve and the threaded rod.

[0011] In a preferred embodiment, a sealing strip is fixedly provided at the junction of the adjusting plate and the inner sidewall of the casting bottom mold.

[0012] In a preferred embodiment, a pad is fixedly installed on the lower side of the bottom mold near the pouring opening. Compared with the prior art, the beneficial effects of this utility model are:

[0013] The screw-adjusting plate system enables stepless adjustment of the pouring thickness. Combined with a detachable top formwork design, the same mold can accommodate various reinforced concrete column cross-sections, significantly reducing mold types and inventory costs. The side sealing strip of the adjusting plate eliminates gaps with the surrounding plate, effectively preventing concrete leakage into the mold and avoiding surface defects. The top formwork vents release pouring gases, reducing common quality defects such as honeycomb and pitting, and improving concrete density and appearance. The U-shaped reinforcing plate on the outer side of the surrounding plate and the reinforcing ribs between the end plate and the surrounding plate form a three-dimensional reinforcement system, significantly improving the mold's resistance to deformation and preventing the risk of mold expansion or cracking due to concrete lateral pressure. The handrail design facilitates mold handling, installation, and unloading, reducing manual operation difficulty. The inclined pouring end of the base plate utilizes gravity to assist in natural concrete filling, reducing vibration time and improving pouring efficiency. The sliding top formwork disassembly structure simplifies demolding and cleaning processes, reducing mold wear. Attached Figure Description
