Why do we all use the concrete laser screeds to level the concrete

For concrete laser screed machine, as the name suggests, it is the use of a laser to make the concrete more flat. Most of these machines are used in factories and shopping malls as well as in factory buildings. Because these places have high requirements for the leveling of the ground.

And its use is very simple. The principle is to use a squeegee to flatten the cement above the horizontal surface, and then a hydraulic vibration motor will unify the elevation of the concrete, and the whole process is carried out using a laser. The advantages of laser screed are many. First of all, the error of flatness is extremely small. Because the laser is used, this land is missing its datum elevation. In this way, the error will be greatly reduced. The second advantage is that the continuity is high and the integrity is up. You can complete a piece of land at one time without having to do it separately.

Now everyone is going to choose to use the laser screed, which leads to an increase in sales. Because now, in order to reduce costs, people will use as little labor as possible and use machines instead. Also, because labor costs are high, and its efficiency is low. And the number of maintenance on the subsequent ground will be greatly reduced. Because of the use of a laser screed, there is little cracking or blistering on the ground. So why the sales of laser screed will increase is here.

For the maintenance of the laser screed machine, it is also necessary to pay attention. The first is that the operation of the machine causes the tire to overheat and can be stopped to cool down, but ice and cold water cannot be used to cool down. Also pay attention to the cleaning of the machine, like the combustion chamber and the valve top. There may be carbon deposits that need to be cleaned up in time.

Trowel machine application in concrete construction and preparatory work

One. Preparatory work before use of trowel machine

1. Construction of wear-resistant coat

Finishing pouring of concrete, use rubber tube or vacuum equipment to remove bleeding, repeat that step more than twice then begin to construct wear-resistant material. constructors shall wear flat bottomed rubber shoes in the middle stage of wear-resistant material construction and water-proof paper shoes in the last stage.

2. First bestrewing, troweling and pressing of wear-resistant material

1) Time or opportunity that bestrew wear-resistant is changed by climate, temperature and mix proportion of concrete. Earlier bestrewing will cause the wear-resistant material sink into concrete and lose effect; while later bestrewing will lose adhesive property and hinder wear-resistant material from combining with concrete and cause stripping because the concrete have been solidified. The way to decide bestrewing time is to stamp on it, when it sink 5mm, you can begin to the first bestrewing.

2) Water desorption on side boundary such as wall, column and formwork is fast, so those places should be constructed preferentially to avoid decrease of effect caused by water desorption;

3) quantity of bestrewing for the first time is two thirds of the whole quantity, mixture should be dropped down equably, use wooden trowel to float after bestrew. After wear-resistant material absorbs enough water, use round trowel machine of 1m to milling.

Two. Construction by trowel machine

1.Usage of trowel machine to Bestrew, trowel and float wear-resistant material for the second time

use guiding rule or straight floating rule to measure levelness in the second bestrewing and adjust unevenness, direction of the second bestrewing should be vertical with that of the first bestrewing.

2) quantity of bestrewing for the second time is one third of the whole quantity, troweling and floating should be executed immediately after bestrew, replaced the roundle by four-patch trowel slice, use trowel machine to work for more than twice. The machine should work lengthways and horizontally in a uniform and orderly way, avoid aggregation of material. Corner should be treated by woody trowel.

3) when the surface material is hardened enough that it can be sunken by finger pressing, rotation and angle of trowel machine shall by adjusted according to hardness, The machine should work lengthways and horizontally more than three times.

surface modification and maintenance

texture left on the surface after construction of trowel machine is a bit messy, in order to eliminate the texture, the last step is to press and float the surface orderly in one direction by thin steel.

2). after wear-resistance floor has been constructed for 5-6 hours, splash curing compound for maintenance, quantity of curing compound is 0． 2 litre per square meters or cover plastic film to prevent craze from water desorption, splash water for one week .

3). after wear-resistance floor has been construction for 24 hours, the film can be taken down, please not to damage edge of the floor.

Three characteristics of laser screed machine construction

The working principle is mainly through its own various equipment. For example, the more advanced laser technology is that he can perform hundreds of data calculations and feedbacks in one minute. There is also the use of complex closed-loop control technology, accurately react various conditions of construction to the brain of the device through a closed loop system, then quickly respond to the program set by the equipment staff. There is also a very good hydraulic control system that can process the various electrical signals reflected by the equipment very quickly. This process is done automatically on the computer side, which is the biggest construction feature of the concrete laser screed machine. All are fully automatic and do not need people to help, only need to set the standard parameters in the early stage.

In addition, the concrete laser screed machine can automatically control the plane whether it is horizontal or vertical. The explanation is that if you do not need to manually manipulate the machine after setting the parameters in a plane, you can perform automatic search and positioning within this working range. Then leveling and vibrating through its own equipment, so that the construction can reach the desired various indicators. The accident personnel only need to carry out simple operations and watch over to complete the project plan. It is a construction machine that can liberate the hands of construction workers. This is the second feature of laser screed machine construction. It can effectively release the labor intensity of the construction workers, thus reducing the expenses to employees to a certain extent.

When the laser screed machine is used, it is necessary for the workers to place the equipment in place, and then the various parameters in the equipment are set to open the machine, and finally the construction personnel perform simple control. A very large area of construction can be completed. Because it uses modern instruments. If you buy a product with a higher specification, it may be used on the mobile phone or on the computer side, and its use method is relatively simple. It is necessary to have a staff member who can repair the construction site to prevent any accidents in the machine and to carry out maintenance in time. This is his third feature is simple and efficient.

Price factors affecting concrete laser screed machine

For the machine, it detects the ground through its own various equipment and then performs the necessary processing. His own machinery consists of many parts. The simplest one is the ray launcher, and the high-frequency oscillating machine. The most critical must be the engine he wears, and the design of the entire machine, which requires specialized personnel to analyze. Next, let me give you a brief introduction about which equipment components should be looked at to determine the price.

For mechanical equipment, if his own engine is big enough, it may work faster than the average machine. But for this laser screed, he doesn’t need his own engine power too much. Because his own engine is usually only used for simple walking, you can watch his engine when you choose. Try to choose a medium-sized engine when purchasing, which is cheap and practical.

The second point is the oscillating machine or the oscillating motor on the concrete laser screed machine. Because it is used to vibrate to adjust the flatness and hardness of the concrete floor, there is not much demand for the engine itself. However, there are higher requirements for using a motor or machine that is shocked. Because only high-powered oscillating instruments or motors can achieve the desired density of the ground, the required quality can be achieved after the cement has hardened. When choosing here, you need to follow the professional introduction of the professional and then choose a shock motor or shock machine suitable for your own construction site.

The third point is the measurement error of the flatness of the laser screed in the plane. Because the laser screed is used for leveling, you need to pay attention to this aspect. You need to choose an instrument that has as high a level of laser measurement as possible depending on the equipment. In order to make you better deal with some big projects. Of course, the price will be higher when the instrument selection is higher.

How to Build First-class Concrete floor

https://www.hkfloormach.com/knowledge-of-laser-screed/how-to-build-first-class-concrete-floor/.

Owners, designers and builders of warehouses and distribution facilities generally believe that the quality of concrete floors is determined by their surface smoothness and levelness. However, the fact is that the flatness and levelness only determine the surface profile of the floor, and can not guarantee its overall quality. In many cases, efforts to achieve special smoothness actually will reduce the surface durability and service life of the floor.

Other factors, such as durability, should also be considered. It is understandable why flatness is often used to judge quality. F is easy to understand, can be stipulated before construction, be confirmed during construction, and be used as a basis for inception. With the development of material handling concepts, such as narrow roadway (VNA) warehouses requiring ultra-flat designated directional floors, F becomes critical. With the improvement of distribution and forklift technology, smoothness and levelness become more and more important for undirectional floor. The development of F numerical system is used to define and measure the surface profile. Designers begin to specify a higher level of levelness for the construction of concrete floors to improve efficiency. They are also looking for concrete floor contractors who can deliver floors that meet higher tolerance requirements.

Twenty five years ago, the F revolutionized the floor construction industry. Finally, there was a way to determine the specified surface tolerance. In order to achieve a higher F value, contractors needed to pay more attention to details. Stricter control over concrete mix design and transportation must be considered. All elements of floor construction would have an impact on the ability to meet the required tolerances. The industry also recognized the value of controlled pouring and lighting environments. As a result, the overall quality of the floor was improved. F value is the driving force for the development of the light-receiving equipment currently in use. Because of the use of advanced tools, such as concrete laser screed machine and ride on trowel machine, requirements that were once difficult to meet can now be easily achieved. Several years ago, the advanced technology of forklift truck and distribution design brought challenges to the floor construction industry. However, today’s situation is just the opposite – the advanced technology of floor construction can easily achieve higher requirements of forklift trucks. F is easy to achieve; the trend in recent years is to achieve higher F value. Surpassing higher F value specified by forklift manufacturers does not bring real benefits. When high F value is considered as the primary concern, appropriate lighting procedures are often modified to find shortcuts. When this happens, the surface durability will be affected. Appropriate FF and FL values are critical to the performance of the floor. However, when the construction is completed and everything related has been done, the reserve money will be paid and awards will be given. So is it all over? Actually, it’s much more than that! Durability must be considered to ensure the service life of the floor and reduce maintenance. Of course, the statement also raises questions. What is durability? How to measure? How to stipulate?

Defining durability is simple. Durability refers to the ability of something to withstand wear and tear. However, it is difficult to measure durability. Durability cannot be measured by an instant verification machine or instrument. We can’t see or confirm until the floor is put into use. Therefore, the industry must use empirical knowledge and experience. In this regard, contractors must turn to those who own and operate facilities for feedback, such as those in the food industry in particular. Yes, food. No one understands the importance of concrete floor quality better than the owners of food or perishable goods distribution facilities, because these facilities require high floor quality and need to withstand all-weather traffic. In this environment, you can quickly see the real benefits of high-quality floors. Food industry personnel will tell you that flatness, durability, abrasion resistance and seam performance together determine quality and service life.

Many factors, including designs, materials, pouring environment and construction technology, can lead to floor cracking, curling and damage. Defected floors with poor quality joints can damage precision lifting equipment and wheels, and have adverse effects on work efficiency and throughput. Although flooring design and construction with poor quality will save money, the owners will pay more operating costs, and ultimately lose much during the service life of the facilities, . In order to determine durability, customer feedback on expectations is necessary. When customer expectations include durability, service life and smoothness, specifications must be more specific and include more details.
