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.

If you want to get more information about trowel machine, please refer to Operation of trowel machine and attentions need to be paid

In floor construction a good trowel machine is required, Hiking trowel machines have been introduced to many projects, they are highly praised by our customers. We supply both ride on trowel machine and walk behind trowel machine, we have whichever you want. See Hiking store.

Operation of trowel machine and attentions need to be paid

For many new users operation of trowel machine is not easy, especial for walk behind trowel machine, the machine always walk toward the same direction wherever the operator direct it to, and it’s hard to pull it back. But for veteran, the operation is comfortable, some even can operate the machine only by one hand.

Actually in order to master walk behind trowel machine, one should not only stick to the principle of “ practice makes perfect”, he also need to know the key skill inertance of this machine. Inertance of of this machine is totally controlled by handle lever, offset of the machine makes it always walk toward the same direction. The inertance deflect when handle lever of trowel machine is pressed down or pulled up. When we hold the handle level on an appropriate position and make the inertance at the center, the machine will rotate in its place

Above is core skill for operation of walk behind trowel machine, now we will introduce detailed operation of this equipment bellow:.

Check if the power supply is connect, ensure of electric circuit;

Press shift knob and start trowel machine;

Hold the machine, adjust balance screw until it is in balance;

Construction is began after the above mentioned adjustment, the operator is only required to control its direction, putting forth all strength is not needed;

Construction steps are the same as that of gasoline engine, trowel first and then polish, please note that plate on the bottom of trowel machine should be taken off during polishing, only vane is required for this step.

Operation of trowel machine decreases labor intensity and increases working efficiency to a great extent, it has better compactness effect to floor, construction effect is obviously better than other ordinary construction machine, it can perform fast mudding, machinery type rotation operating system, sensitive reaction, effortless control, equipped with excellent Honda engine, powerful and reliable motor and stable operation, all of which make the machine superior in construction industry. Unique handle leveler allow the operate control it safely.

Although trowel machine is easy to operate, the following matters need to be paid attention to:

Before operation check if the engine, switch, cable and wire splice are normal, make sure they are conform to specifications and install leakage protector;

Check and clean up sundries on trowel plate before usage to avoid bounce of the whole machine during operation;

Execute test run after power supply is connected, the blade shall rotate in a clockwise direction, reverse rotation is not allowed;

Operator shall wear a pair of insulated shoes and gloves, cable is taken by staff personnel, the staff personnel should also wear a pair of insulated shoes and gloves to prevent electric shock accident caused by cable insulating layer;

If there is any problem with the machine, power supply must be cut off before repairing;

Above are operation methods of trowel machine, if you want to know more about trowel machine please click trowel machine for sale.
