Today, the use of concrete laser screed is commonplace. It’s an essential tool across a broad range of projects, from large industrial warehouses to commercial establishments and residential housing projects. Its advent continues to revolutionize the concrete industry, driving forward the demand for efficiency, quality, and safety.
How does Concrete Laser Screeding Work?
Explanation of the process
The process of Concrete Laser Screeding begins with preparing the subbase for the concrete pour. Once the subbase is ready, the concrete is poured onto the surface. The magic of laser screed comes into play at this point. The screed is a machine equipped with a flat, vibratory plate and attached to a hydraulic arm. The device is guided by a laser system that is independent of the uneven surface level of the concrete.
To initiate the screeding process, the laser screed machine is driven onto the concrete. The laser-guided system calculates the distance from the screed head to the level string line, a predetermined set point. As the screed moves along the surface, the computer system continuously adjusts the hydraulic boom, ensuring the screed head stays at the set height.
The rotation of the machine’s vibratory screed plate pushes the excess concrete mixture ahead of it, filling any valleys and removing any peaks along the surface. In essence, the concrete is compacted and leveled in a single pass of the machine. This process ensures an accurate, leveled layer of concrete, allowing for a smoother, more precise surface, whether flat or sloped.
The screed compacts the concrete by vibrating the mix, thereby promoting maximum bonding and strength. Once the excess concrete has been successfully spread out, the freshly screeded surface is ready for final finishing, such as troweling to smooth out the surface even more or applying a textured finish for improved traction or aesthetics. By using a laser screed, the operator can evenly distribute the concrete mixture while eliminating low spots and high points, leading to a perfectly level surface every time.
Detailed technical specifications
Concrete laser screeds employ sophisticated technology to ensure impeccable accuracy and efficiency. The technical specifications of a standard concrete laser screed machine include several critical components that come together to ensure smooth and flat concrete surfaces.
First, every machine has an engine that powers the equipment. Most modern machines use diesel engines due to their high output power and fuel efficiency. Engine power can range from around 40 to over 100 horsepower based on the model and the complexity of the tasks it’s meant to perform.
Second, the screed head is a vital component of these machines. The head is typically made of hardened steel or aluminum and can vary in width depending on the model, from 12 to 24 feet. The head both levels the concrete to the desired height and vibrates to compress and remove air pockets.
Another crucial aspect of the laser screed is the laser system itself. High-level precision lasers are used, often having an accuracy rating down to one millimeter. These lasers level by referencing established elevation points, which the screed head automatically adjusts to match.
The machine also comes with an automatic leveling system, consisting of laser receivers and hydraulic valves. This system governs the height and angle of the screed head in real-time, allowing for high precision concrete placement.
Finally, the machines have a control system often featuring a user-friendly dashboard with a color graphic display that makes it easy to operate. Modern units may have GPS systems for better navigation and accuracy.
Each machine’s specific technical specifications will differ depending on the brand, model, and design variations. It is crucial to review these specifications before deciding on the machine that best fits one’s concrete construction needs.
Use of laser technology in screeding
Laser technology plays a pivotal role in the process of concrete laser screeding, contributing significantly to the accuracy, speed, and overall quality of the operation. Its primary function is to provide a precise level reference for the screed head to follow.
The system typically employs a series of high-performance lasers, usually installed at various vantage points around the work-site. These lasers project an invisible light plane over the entire area where the concrete is to be leveled. The plane serves as the ideal “finish grade” for the concrete. Irrespective of the size or dimensions of the work area, these lasers ensure that an unerring level plane is maintained throughout.
The laser receivers mounted on the screed head continuously interact with the laser plane. Doing so, they detect any deviation from the desired level. This information is then instantly relayed to the screed’s hydraulic system, which instantaneously adjusts the elevation of the screed head to align perfectly with the intended finish grade. Thus, through this interaction of lasers, receivers, and the screed’s hydraulic system, a remarkably flat and level concrete surface is achieved even across vast areas.
It’s crucial to note that this process isn’t just a one-time thing. The laser receivers constantly monitor the laser plane throughout the screeding operation. This continuous feedback mechanism enables real-time adjustments, ensuring even the minutest of deviations are instantly detected and corrected. The result is a concrete surface of superior flatness, levelness, and finish. The enhanced precision leverages laser technology, which traditional screeding techniques simply can’t match.
