4. The industry's first Mitsubishi multi-function touch screen control panel replaces the traditional button control mode and makes the human-machine interaction smoother;

5. FRP chassis cover, compact body design, greatly reduce the weight of the fuselage, can adapt to different operating conditions;

6. The original light loss mode can adapt to different working environments, and it will not affect the construction of the equipment when the laser is blocked;

This is the characteristics of the concrete laser screed machine of a company I know, Sanren Machinery, concrete laser of different enterprises.

The screed machine has some characteristics that are different from other products, but all concrete laser screeds are basically high efficiency and good construction effect. If you want to know more, you should go to the manufacturer who makes the machine.

Concrete laser screed machine operation:

1. Preparations.

The construction of the flooring project needs to be fully prepared. From laying the substrate and reinforcement mesh - setting up the force transmission rod - placing the buffer belt - concrete mixing, every step is grasped in detail.

2. Concrete paving + laser leveling.

The mixed concrete of the mixing plant is paved on the gravel substrate by pump transportation, and the paving speed of the laser leveler should be appropriate, and the manual quickly assists in flattening.

Third, the initial grinding of pulp.

About 3-4 hours after the concrete paving of the laser leveler, when the Master does not have clear footprints, it is the best time, use a single disc and a double disc trowel, install the flattening disc, and repeatedly rub the concrete when the concrete is initially set, and put forward the concrete slurry.

The laser emitter is arranged independently, and the overall paving of a large area is ensured, and the consistency of the ground elevation is ensured, the error is small, the construction joints are reduced, and the maintenance cost of the ground is greatly reduced; Concrete laser leveling machine can reduce the labor intensity of construction personnel, improve the efficiency of the construction stove and the quality of construction, improve the strength and compactness of concrete, and the overall flatness is better

Advantage 1: Save manpower input.

People who have done flooring know that in the construction of a large area of flooring, the manual construction of traditional craftsmanship, the number of teams is composed of about 15, and the workload of a single shift is within 700.

The use of Sanren Machinery Shanxi concrete laser leveling machine, applied to large-area floor construction, the operation efficiency is greatly improved, about 6 workers to form a construction team, 300 paving work can be completed per hour, the average single shift can complete 2500 3500, especially suitable for tight construction period, large paving area, high quality requirements of the project.

Advantage 2: Save capital investment and shorten the construction period.

Traditional labor needs to support the formwork in advance, which wastes labor, delays the construction period, and cannot effectively return funds. Concrete laser leveling machine, high degree of automation, the realization of one-time paving construction of large area blocks, so that the middle of the block does not need formwork, while reducing the formwork and channel steel, the construction process is further reduced, and the construction progress is accelerated.

Advantage 3: The flatness error is extremely small.

The process principle of the concrete laser leveling machine is to rely on the gasoline generator to generate electricity, and the laser measurement and control system, computer control system and servo drive system are driven by electricity to complete the leveling work with the leveling head, and the leveling of the Sanren mechanical laser leveling machine does not need to pull the control line, nor does it need the side template to control the ground elevation, and is controlled by the laser measurement and control system on the leveling machine in real time, as long as the laser emitter is not disturbed, regardless of the leveling machine moved to the first level, it can ensure that the overall elevation of the ground after paving is not affected.

Advantage 4: The ground is more integral.

Traditional process construction, one day to support the formwork, one day to pour concrete, can only be a piece of jump construction, the limitation is very large, can not be continuous operation, and the integrity is not good, easy to cause the construction joint accumulation error.

Concrete laser leveling machine, applied to floor construction, it is very easy to realize the one-time overall paving of a large area of floor, this paving technology can be arbitrarily divided into blocks according to the needs of the construction, continuous operation to the completion of the entire floor, so that the integrity of the ground is better, which can not be done by using traditional construction technology.

Advantage 5: The ground is more dense and uniform, reducing the cost of later maintenance.

The laser leveling machine uses a high-frequency vibrator of 4200 times per minute, and the uniform high-frequency vibration of the vibrating plate of the leveling head makes the concrete floor dense and can avoid the ground cracking caused by the stress concentration caused by deformation. It can reduce cracks, effectively solve the problems of ground hollowing, shelling, cracking and inequality, and greatly reduce the later maintenance cost of the floor.

One. Advantages of laser leveling machine:

1.High quality of construction.

The laser leveling machine leveling the ground can significantly improve the flatness of the ground, and the ground constructed by the laser leveling machine and the traditional method is detected at 22 points respectively (one point is detected every 5mx4m), and the average flatness is sum, and the leveling quality of equipment such as the laser leveling machine is more than 3 times higher than that of the traditional method.

The application of laser leveling machine and other equipment can realize large-area construction, reduce a large number of construction joints, reduce the collapse of concrete, and improve the strength of concrete, so that the integrity of the ground is good and cracks are not easy to appear.

2.The construction speed is fast.

The use of laser leveling machine and other equipment to construct concrete slabs, than the traditional beam vibrator method to improve the work efficiency by 3 times, save 30%, an average of 2000 per day can be completed, especially suitable for the shape of simple, large concrete surface layer construction.

3.Reduce the amount of side mold support and dismantling.

With 20,000 concrete pavement statistics, the traditional method needs to dismantle 5800m side formwork, and the use of advanced equipment such as laser leveling machine, support and dismantling only 2500m, reduce the modulus by more than 74%.

4.High degree of automation and low labor intensity.

The use of laser leveling machine and other equipment to make the heavy manual labor into mechanical paving, vibration, leveling, slurry, plastering, surface plastering, so that the operator is reduced by 30%, and colleagues reduce labor intensity.

5.High economic benefits.

The application of laser leveling machine and other equipment saves 2-3 yuan compared with the traditional process, less seams, and reduces the maintenance cost in the later stage, so that the economic benefits are significantly improved.

Two. Issues that should be noted.

1) Due to the high construction efficiency, the later cutting joints must keep up, and generally each laser leveling machine is equipped with 7-8 cutting and sewing machines to be full.

Sufficient requirements. 2) In the early stage, it is advisable to use plastic film to cover and cure, and then cover the non-woven fabric after cutting.

3) In the construction process, due to the action of concrete side pressure, the reinforcement mesh is easy to be displaced horizontally, so it is directly in the adjacent reinforcement mesh.

The isolation bench is set aside, so that the horizontal displacement of the steel mesh sheet can be effectively controlled, and the bench can be used in turnover.

Three. Epilogue. Advanced equipment such as laser leveling machine is especially suitable for wharves, storage yards, highways, airports, large squares, parking lots, municipal roads and other projects with simple shape, large amount of action and high construction quality requirements.

I also want to know, and when I sign the contract, I will go to the manufacturer.

The characteristics of the concrete laser screed machine are as follows:

1. High efficiency and fast construction speed: 200-600m of engineering volume is completed per hour.

2. Good flatness: according to the current state of commercial mixing, it can reach the flatness of 3mm 3m, which is 1000

The elevation difference in the m range is 20mm.

3. Simplify the process and save labor: save the formwork process, and a single shift is equipped with 6-10 people, which can complete 3000

m days of engineering quantity.

(1) The leveling principle of the laser leveling machine is realized under the automatic control of the computer by using precision laser technology, closed-loop control technology and highly precise hydraulic system, which is the most prominent feature that distinguishes it from other floor construction technology.

2) The leveling principle of the precision laser leveling machine is to rely on the leveling head driven by hydraulic force, cooperate with the laser system and computer control system to complete the leveling work at the same time as automatic leveling. The leveling head is equipped with an integrated design scraper, vibrator and whole plate, which integrates all leveling, leveling, vibrating and compaction work in one and completes it at one time. The computer control system automatically adjusts the elevation in real time 10 times per second, and the vibration frequency of the vibrator with balanced design reaches 3000 minutes.

3) The laser emitters used to control the ground elevation are arranged independently, so that the floor elevation is not controlled by the template and does not produce cumulative errors.

4) The laser leveling machine can also automatically control the longitudinal and transverse slopes, which is also completed by the laser system, computer system, hydraulic system and mechanical system. For complex shapes of the ground with high requirements for drainage, a three-dimensional special-shaped ground treatment system can also be selected.

The compact size and lightweight, flexible and innovative design of the laser screed machine can not only move more quickly and effectively on complex work sites, but also make the ground flatness quickly reach laser-level accuracy. However, the construction process of using laser leveling machine is also different from ordinary manual construction, and the following will give you some correct Sanren machinery construction process.

The gourd ten centimeters are attractive.

Broken mother-in-law Liu Hulan.

Smooth construction process laser.

Automatic manual dual control mode, flexible control, single operation is sufficient; Two-wheel independent movement, differential turning, flexible and convenient; The laser emitter is arranged independently, and the overall paving of a large area is ensured, and the consistency of the ground elevation is ensured, the error is small, the construction joints are reduced, and the maintenance cost of the ground is greatly reduced;

Main construction process:

Civil engineering formwork (bottom formwork) steel bar royal tie concrete pouring and laser leveler elevation control "Thunder Dragon" laser leveling machine for concrete leveling Professional and technical personnel with 3 meters of scraper for accurate leveling of single disc trowel slurry smoothing Professionals with 3 meters of scraper precision leveling Double disc driving trowel professional operation of surface layer collection Finished product protection.

1, civil engineering formwork (bottom mold): civil engineering formwork (bottom form) and normal according to the drawing design and construction specifications acceptance standards as the same elevation control is strict, scaffolding support firm, it should be noted that the "clear water concrete" floor (ground) surface and concrete pouring synchronous construction, in order to facilitate mechanical construction, there should be no higher than the building (ground) elevation of the template or support firmware, except for the reserved and embedded elevation provisions.

2. Reinforcement Yuzha: Because the surface layer is a one-time molding of the building (ground) surface using the protective layer of reinforced concrete, the reinforcement Yuzha must ensure that the concrete protective layer is sufficient, and the steel bar, stirrups or weldments are not allowed to be exposed on the concrete pouring surface layer according to the regulations, resulting in the mechanical hitting on the steel bar, which not only destroys the machinery but also destroys the surface layer of the building (ground).

3. Laser leveler controls concrete pouring: before concrete pouring, the elevation is set on the column bar, and the accurate elevation is led to the laser leveler control system, and the concrete pouring personnel scrape the elevation in the range of 5-10mm higher than the design elevation, so as to lay a good foundation for the next laser leveling machine.

4. "Thunder Dragon" laser leveling machine leveling: in the case of accurate elevation setting of professional and technical personnel, there are mechanical operators to accurately level the concrete surface under the control of the laser leveling instrument, and the leveling machine will automatically calibrate and control the leveling machine at a frequency of 10 times a second, so as to ensure the accuracy of the leveling plane.

5. Professional leveling: This process is to wait for the concrete pouring surface to be completed when the water secretion is completed, use a laser leveler to remeasure the puddle, fill the water with concrete, and use a 3-meter scraper bar to scrape the surface layer 360 ° rotation, so as to achieve comprehensive control of flatness and smooth the details of the edge of the column root template, and repeatedly detect with a laser leveler until the requirements are met.

6. Single-disc trowel smoothing and slurry: while pouring the concrete in an orderly manner according to the specifications, using the time difference of concrete construction, the early pouring concrete will reach the initial setting earlier, and the initial setting (people have 2-3mm footprints on the concrete surface), then use the "Thunder Dragon" single-disc trowel and trowel disc to carry out cross-pulp trowel wiping to ensure the smooth control of the mechanical operation process.
