Hollow core slab cutting is an important stage in the production of reinforced concrete products, hollow core floor slabs. High-precision equipment is required to obtain smooth edges, adhere to dimensions and minimize waste. The use of specialized saws ensures high processing speed, minimizes the risk of damage to reinforcing elements and guarantees an even cut line. That is why the saw for cutting floor slabs becomes an indispensable tool in any modern production of construction materials.
Today, the quality requirements for reinforced concrete products are growing rapidly, and simple mechanical processing methods are no longer sufficient. The market demands precision, speed and safety - three factors that only specialized industrial saws can provide.
Why you need a specialized saw for reinforced concrete floor slabs
Using conventional circular saws to cut reinforced concrete is extremely inefficient. Conventional tools fail quickly, overheat and result in uneven cuts, which is unacceptable in the production of reinforced concrete products.
The specialized saw for cutting floor slabs takes into account the specific features of the material:
- Presence of prestressed reinforcement inside the slabs.
- Voids of various diameters that weaken the structure of the product.
- High hardness of the concrete mixture.
Thus, the equipment should have high power, resistance to wear and tear and the ability to make clean and accurate cuts even in difficult conditions.
Main characteristics of slab saws
Modern slab saws have a number of key features that distinguish them from conventional construction equipment:
1. Motor power: typically, between 25 kW and 55 kW, depending on the model.
2. Saw blade diameter: up to 1300 mm, allowing slabs up to 500 mm thick to be cut.
3. Feed speed: adjustable automatic feed system for perfect quality
4. Safety systems: automatic shutdown in case of emergency, safety guards, braking systems.
These parameters have a direct impact on the efficiency and durability of the equipment in an industrial environment.
Design and operating principles of the equipment
The design of slab saws is oriented on stable and accurate operation in factory conditions. The basis is a strong rigid frame, resistant to vibrations. It is equipped with a high-power electric motor with a gearbox, which transmits the torque to the saw blade.
The blade is cooled by a fluid system that prevents overheating and increases the service life of the tooling. The saw unit is mounted on a carriage with automatic drive, which ensures precise and smooth movement along the plate.
Control is realized through the operator panel, where you can set the cutting parameters - depth, feed rate and cutting direction. The work itself is based on the principle of directed passage along the workpiece: the disk moves horizontally or vertically, depending on the model and task.
Cutting quality requirements for floor slabs
In the industrial production of reinforced concrete hollow core floor slabs, cutting accuracy and precision are particularly important. The permissible deviation of the line is no more than 2 mm on a 2-meter length - this ensures the geometry of the assembly on the construction site. Any chips, cracks or damage to the edge are considered a defect, especially if they affect the voids inside the product.
Equally important is the safety of reinforcing elements inside the slab - the disk must accurately pass between them or cut without loss of strength. Fulfilling these requirements is only possible with quality equipment with precise setting and stable feed.
A poor-quality cut can lead to weakening of the load-bearing characteristics of the structure and defective product, which is unacceptable in industry. Therefore, the choice of the right saw for reinforced concrete products directly affects the profitability of production and durability of construction projects.
