Adjustable floor to the joists : installation features

Modern methods of floor leveling to dramatically reduce the time and effort.Previously used only for this concrete floor and waited for it dries a few weeks, but today for finishing facilities can begin immediately after the alignment.Adjustable floor supports lag given the opportunity to raise the level of the surface at any height, hide under the floor of communication at any time change the set parameters.Dry floor screed on regulated joists passes quickly and accurately, in contrast to the classical grout.If you want to align the floor for a couple of hours, we will explain how to do it.

device adjustable floor

installation of floor joists on regulated consists of installing themselves lag and fastening them over rough coating - subfloor.lag device in this case is very interesting and offers a lot of opportunities for domestic masters.But first let's talk

about the features and use of controlled device sexes.

Flooring can be made from any material having sufficient strength, durability and hydrophobicity.Very good in this respect has proved water-resistant plywood and drywall.However, the final choice still depends on the type of flooring and its installation requirements.Plywood, for example, is suitable for laying laminate flooring and linoleum.If you want to oblitsevat tiled floor, the floor is better to make water-resistant gypsum board, DSP, or similar materials.For wood flooring or decking choose planed board.

adjustable floor on joists perfect for both residential and for office space.It is well withstand heavy loads up to 2.5 t / m², so the technology is often used in the construction of shopping centers and gyms.Long service life - about 50 years - allows it to compete with major competitors (the floor on conventional joists, concrete screed, dry screed).

There are several varieties of controlled floors defined by the support member:

  1. Laghi - a great alternative to the concrete screed.The technology allows you to raise the level of the floor at 5 cm or higher.The remaining space at the bottom can be used for laying engineering communications, additional insulation (if you live on the first floor) or sound insulation (if the apartment noisy neighbors living below).Installation takes a minimum of time and effort with all the necessary materials and the most simple tools (drill, hammer, wrenches).
  2. Plates - instead of lag on the lifting elements attached plate.The maximum floor raising the level of 3 cm. This method is suitable in cases where you need to quickly align the floor or to insulate it.Hide down the communication will not work - too little space.There will fit only a thin wire and cable - by phone, Internet, etc.

Advantages and disadvantages of regulated lag

more innovation appears Every year, which have many advantages, but unfortunately, only rare exceptions without drawbacks.Consider the pros and cons of the use of regulated lag wooden floors.

Advantages of controlled floors:

  1. design makes the floor surface is perfectly smooth and avoids any swings horizontally.
  2. Logs can even be mounted on a curved base.
  3. After installation under the floor is free space in the 5-25 cm, which can be used with advantage.
  4. for assembly and installation, you will need only a screwdriver and a circular saw - no glue mixtures and solutions.
  5. Make a flat floor can be just a few hours.
  6. Adjustable feet allow the rigid connection of the new flooring to the substrate.
  7. adjustable floor cost is almost the same as that of the concrete screed, that is low.
  8. After installation the floor is immediately ready for laying the floor covering.

determining factors in the selection of adjustable floors for many are low cost and basic installation.

Disadvantages of an adjustable floor on joists:

  1. Over time, these floors are starting to creak.This can be prevented even at the installation stage, carefully de-dusted surface of the slab after making holes.Another point - the dowels should be to drive to the limit to stand then do not stagger.But this will only delay the emergence of a squeak.Avoid it will not work because of the physical characteristics of the wood material of the lag - it "breathes", narrows and expands from temperature changes, shrinks and swells from moisture.
  2. Another minus is that if you need to raise the level of the floor, say, 15-20 cm, the sound of footsteps on it will be very loud.Fix it helps thick sound absorbing lining and insulating mats.This will increase the cost of the work, but will make the floor warmer and quieter.

mounting Features

Adjustable lag can make yourself or buy a ready-made set of gender.Home design - regulation mechanism to align the surface with absolute accuracy.Complete systems are quite expensive, and finding them is not always possible, therefore we recommend to consider the option of creating an adjustable floor joists on the hands.To do this, you need the most common materials that can be found in any hardware store.

06

There are two variants of arrangement governed by gender, each of which has its own nuances, but the complexity of the installation, in both cases at the same level.Both methods give the same qualitative result, if all the technology requirements have been met, so the choice depends purely on personal preferences and capabilities.

Logs heels

The most common way of controlled device lag sex.As supporting elements using ordinary steel studs.Let us consider briefly the construction of floors:

  1. to lag require dry pine timber with a square cross section of 50 mm.
  2. use hairpin with two M6 nuts, washers and the anchor sleeve for adjustable feet.
  3. Drill a hole in the concrete floor and a hammer in his thrust anchor sleeve.Beaten to the very end, so that it is flush with the surface.
  4. Screw on the lower pin nut and washer - they will be placed under Lagoi.
  5. lag Drill a hole with a diameter slightly larger diameter studs.
  6. Push pin on a log.
  7. Adjust the height of the joists position by tightening the nut underneath.When she takes the required position, fix it by screwing the top nut.

Before you get started, make a precise calculation of all necessary materials in accordance with the area of ​​the floor.You also need to prepare the room - move all the furniture, sweep up and remove dust as much as possible the surface of the concrete screed.

How do adjustable floor joists under:

  1. Lay the boards parallel to each other with about 30 cm increments to ensure sufficient rigidity of the floor.If you place the bars on, the floor covering can not withstand the load and bend.When the alignment of the lag expose the indentation from the wall in the first 5-7 cm is convenient to put the two extreme lag, and then -. Intermediates.
  2. Drill holes in the joists studs, making pre-marking pencil.Pick up a drill bit with a diameter greater than the diameter studs, so that she could freely enter and rotate inside the bar.Since most everything for adjustable floors in homes using M6 stud, the diameter of the hole for it must be 8 mm.The studs must be removed from each other not more than 50 cm.
  3. Make countersink on joists using drill pore diameter is a few millimeters greater than the diameter of the washer.Countersink allows drown washer and nut to mount the flooring and lag the maximum level.Logically, the countersink depth must be the same or slightly larger than the total thickness of the nuts and washers.
  4. When using a drill or punch a hole in the concrete screed by timber.This will eliminate the inconsistency studs and lag.
  5. Score anchoring struts into the openings in the screed and screw to the stud.
  6. Screw the nuts on them, and then put the puck.
  7. After all the pins move on to the installation log.Push the logs one by one and adjust their height by adjusting the position using a spirit level.The preferred use for this laser level, but you can cope and conventional gidrourovnya.As a result, all logs should be withdrawn in a single plane.
    Process - installation - lag
  8. Fix the bars, wearing hairpins second washers and nuts and cut the protruding ends of the grinder or hacksaw.
  9. Place the insulating layer and route communications.As a heater, you can use an inexpensive mineral wool, expanded clay or foam.
  10. remains only to attach the deck to the joists with screws for wood.

most complex and demanding attention to the time of installation - proper installation of anchors.Since the slabs are usually hollow, the anchors have to drive very carefully and make the most tightly.Always make sure they do not fall into the plate.The process is complicated by the fact that the reinforced concrete slab, that is, it has a reinforcing cage.According to the "law of meanness," very often when drilling holes for anchors fall exactly into the fitting.

Laghi Corner

Installation lag on the corners is not fundamentally different from the technology described above, except that the support elements are not studs and steel corners.This option is ideal in case drive the anchor does not work.

Progress:

  1. Check the surface of the floor of the future.
  2. bars Lay on the floor with a distance of 25-35 cm.
  3. Note line arrangement of bars.
  4. In marked lines on the concrete screed attach steel corners at a distance of 40-50 cm. The size of the corner, choose depending on what level you want to raise the floor.In this area should be slightly less than the desired lifting height, because it will take into consideration the thickness of the floor and finish.Otherwise you will have to saw off the extra part of the corners.
  5. Attach the boards to the corners, adjusting the position using a spirit level.
  6. To increase the rigidity of the structure is recommended to install additional corners on the back side lag.
  7. Lay insulation and communication.
  8. You can then mount the finishing floor.

Corners 1

most difficult part of this work is to install the extreme lag, which are located closest to the walls.The short distance between the wall and Lagoi does not allow "turn around" and fully work tools.Dream a little, it is possible to solve this problem is quite simple - to fix the area not to screed and the wall.You can also skip the bar around the perimeter of the room, which makes the floor much easier to adjust, make the floor stronger and reduce the complexity of the work.

We describe how to work with wood constructions, but these are not applicable technology for adjustable floors on metal joists.They are used where the load is too large for the timber elements, for example, in industries, factories, parking lots, etc.We hope our article has helped you understand how to quickly and easily make a smooth and radiant floor heating at home.
