Wall Column Brackets / Plum Blossom Brackets / Wall Column Spacers: Versatile Tools for Reinforcement Positioning and Cover Control
In the construction of reinforced concrete wall and column structures, the precise control of reinforcement spacing and the stable control of cover thickness are crucial to ensuring the balanced stress and durability of the structure. Wall column brackets, plum blossom brackets, and wall column spacers (named differently due to slight differences in shape and application scenarios, but actually belonging to the same type of plastic auxiliary components) have become indispensable "invisible guardians" in wall and column construction with their unique design and reliable performance.
I. Core Product Characteristics
These brackets/spacers are all injection-molded from high-strength engineering plastics, which have excellent compressive strength and anti-aging properties. Compared with traditional mortar spacers or metal brackets, plastic materials are not only lightweight and easy to transport, but also can avoid the potential impact of rust on reinforcement and concrete structures. At the same time, their smooth surfaces will not damage the anti-rust layer of reinforcement, ensuring the durability of the structure in details.
Their shape design is quite ingenious: "plum blossom brackets" get their name from the plum blossom-shaped distribution of 卡槽 (clamping grooves) on the surface, which can fix multiple steel bars at the same time to ensure uniform spacing; "wall column spacers" focus more on single-point support, controlling the cover thickness through precise height; while "wall column brackets" have both supporting and positioning functions, adapting to the needs of steel bars with different diameters.
II. Core Functions and Application Scenarios
The core functions of these products are reflected in two dimensions: first, stably supporting the reinforcement spacing. Through preset clamping grooves or supporting structures, the steel bars can maintain the designed spacing during binding and pouring, avoiding displacement caused by extrusion and collision; second, precisely controlling the cover thickness of concrete components. They provide a fixed gap between the steel bars and the formwork through their own height, ensuring that a cover meeting the specifications is formed after concrete pouring.
Their application scenarios are mainly concentrated in the construction of various wall and column structures:
- Building walls: Used for positioning the reinforcement of shear walls and frame columns, ensuring that the spacing between vertical and horizontal steel bars meets the design requirements, and guaranteeing the shear resistance and load-bearing capacity of the walls;
- Beam-column joints: In the connection part of columns and beams, assist in fixing dense steel meshes to prevent insufficient cover thickness due to too dense steel bars;
- Special components: Such as thin-walled wall columns of elevator shafts and pipe wells, through precise support control, avoid reinforcement deviation caused by concrete pouring pressure.
III. Specification Parameters and Adaptation Range
The product provides 7 standardized sizes (heights), covering the cover requirements from 15mm to 50mm. The specific adaptation scenarios are as follows:
- 15mm: Suitable for components with the thinnest cover requirements, and is the basic specification to prevent reinforcement exposure;
- 20mm, 25mm: Commonly used in wall and column structures of ordinary civil buildings, adapting to conventional load requirements;
- 30mm, 35mm, 40mm: Suitable for wall and column structures of industrial buildings with medium loads or components with fire and corrosion protection requirements;
- 50mm: Designed for heavy-duty wall columns or thick covers in special environments.
It is worth noting that these brackets (plastic spacers, wall column spacers) are mainly used to clamp steel bars with a diameter of 6-12mm. The size of their clamping grooves has been precisely calculated, which can firmly fix the steel bars without causing deformation due to excessive tightness, ensuring the balance between construction convenience and structural safety.
Summary
Although wall column brackets/plum blossom brackets/wall column spacers are small plastic components, they play the role of "precision regulators" in the construction of reinforced concrete wall columns. Through scientific design and standardized specifications, they simplify the two key processes of reinforcement positioning and cover control, which not only improves construction efficiency, but also fundamentally ensures the mechanical performance and durability of wall column structures. In today's pursuit of refined construction, these "small but professional" accessories are building a solid defense line for building quality with their reliable performance.
