Making screeds for concrete placement

It screed for laying concrete makes this the most robust coverage and quality.

itself coating of concrete has lots of advantages.

However, in order to make it really had high specifications, it is necessary to fill in all the rules of the existing technology.

properly prepare a solution and put the formwork is only half the battle, the concrete must be properly and correctly laid.

If after drying the inside of the concrete base will zavozdushennye area and voids, such coating is not likely to last for a long time and lost a lot of quality.

is therefore very important in the process of pouring grout, hold it carefully ramming and compacting.This will release the air caught there, and thus to remove voids.

This work You can do manually, by piercing a piece of fresh mortar reinforcement, but no one does not guarantee the quality of the concrete, and with a large area fills do it will not be easy and it is problematic enough.

It is in order to simplify the work and make the best possible coverage and universal used for concrete screed, which can be bought, but you can do at home with their own hands.

principle and foundation work

general screed concrete is a special unit, which consists ofrigid solid frame and a special vibrator, leading her to asynchronous movement.

as carcass material is common to use thick aluminum or high-quality alloy steel.

The main element of the vibration system acts as the engine that runs on gasoline or electricity.

order to bring it into action, it is necessary to start the engine, which will transmit a certain rotational movement of the vibration system, and that in turn define the required motion of the frame itself.

Thus, frame running screed makes concrete solution to move, taking away from it all air voids and carefully ramming.The length of the slats can be from a few tens of centimeters to ten meters.

floating screed which is equipped with a gasoline engine, has compared to large electric power.

In most cases, floating screeds with petrol drive used to work in open spaces, as the engine emits harmful impurities.

if necessary to carry out the work with concrete in confined spaces using a floating screed, which acts as the drive electric motor.

It should be noted that with screeds can not just ram a solution and to remove from it zavozdushennye space.

This floating device is also actively used to align the surface of virtually any size as required.

This versatile equipment can be purchased at any specialty store, but its cost is quite high.

The best option would be to gather his own hands, the more it will be able to do each.

preparatory stage of work

floating screed in technical terms is arranged is not difficult, however, to build its own hands the minimum required knowledge in the field of construction.

As noted above, it is much easier to buy a device in the nearest specialty store, but if you want to save money and build it with your own hands, you should carefully prepare for work.

for its self-assembly, you must have the basic skills to work with welding and electricity.It is crucial - when floating screed will be collected by the hands, to comply with safety regulations.

This is due to the fact that most of the work will be carried out using a three-phase trigger.

optimal size of the working of the screed experts say three meters, and the engine power is better to take no more than half a kilowatt.

As practice shows, floating screed with these parameters will work with the solution, the thickness of which is up to twenty centimeters.

To manufacture this versatile device with your hands need to have on hand channel and fittings, as well as the corners of steel or aluminum.

In addition, you need to stock up on bolts with different diameter, insulation rubber, high-quality three-phase cable.

necessarily require an electric motor of appropriate power, suitable starters for him, as well as the installation itself vibrating.

From the tool should find welder, drill with a screwdriver, and a set of wrenches.

All materials must be of high quality and reliable, since its operation is subject to a floating screed is sufficiently high loads.

Besides collecting device, it is necessary to comply with the maximum safety and to ensure protection of all electrical components of the equipment.

desirable at a preliminary stage of work is a detailed drawing of the collecting unit and all work carried out in strict accordance with it.

Assembly

device to a homemade floating screed was able to successfully carry out all of its functions and has a high durability, all the work on its assembly should be done correctly.

The work should start with the production of handles, which can be used for reinforcement.Handles should be given a curved shape and attached by welding to the profile.

For greater reliability in addition to fixing the welding is recommended to use screws.

To protect human while working with vibrorekoy, handle carefully insulated rubber material.The following is the basis of the device laid on a flat surface or workbench table.

When you are ready for installation on the device is an electric motor.

to vibration during operation of the device is distributed as uniformly as possible, the motor is installed in the central part of the profile.

Strengthen its best with the two corners of the metal.Can corners originally attached to the engine itself, and only then to the frame, and you can do the opposite.

vibration mount installation should be performed so that the cable running from it was possible firmly fixed, as the handles, and on the profile.

starter motor for best mounted on one of the arms, however, possible and on the motor itself.For ease of screed, its folding design can be made.

This requires profile cut into two equal parts and to make the bolted connection.

To align thick layers and compacted solution device must have either a double or a frame structure.In this case, the manufacturing process is exactly the same as in the first case.

difference consists in the fact that the engine will have to be mounted on a special attachment in the middle of all screed constructions.

Making screeds with petrol engine is much easier, as there is no need to attach to the core electrical cable.

Recommendations and advice

Many experts recommend doing screed mounting frame in three separate locations.

better if floating screed will be completely folding design, and for this frame should be made of four independent parts.

Use screeds should be only for its intended purpose, it does not overload the engine is installed.This will increase the life of the unit.

tamping process solution should be evenly and accurately.

Do not pour a large amount of concrete, as in this case, there are problems with its tamper, screed and she will be overloaded.Also, it does not follow that the device is idle.

In the case where the solution falls below the level of the rails, it should be added with a shovel.

Collect screeds yourself at home with the right approach to business can each.

course, much easier to buy a universal device, but in this case will have to spend a lot of money.

Do not forget that in many respects depends on the durability of the device compliance with the rules for its use.
