Reducer for a concrete mixer do it yourself

Vibration devices are widely used in the industrial preparation of mortars and concrete mixtures, since they provide the best quality of the final material. They are very simple in their design, and then make them your own hands quite easily.

During operation, the components begin to actively mix, and water is gradually added until the required degree of solution density is obtained. At the end of the process, a hatch is opened in the lower part of the tank, and the finished mixture falls into the pan or car body.

Structurally, such a concrete mixer is a fixed container located vertically. In the upper part, the necessary components are loaded for preparing a mortar or concrete, a certain amount of water is added and an immersion vibrator is lowered in the middle.

If you already have your own immersion vibrator or you have the opportunity to purchase it, then it will not be difficult to make such a concrete mixer yourself. (more…)

Thermal insulation of the walls of the house foam

For this purpose, “umbrellas” are used – special dowels for foam plastic. having a plastic head. Their length is selected taking into account the thickness of the plates. Metal mounts that can damage fragile plastic are not used. In addition, the metal has a different coefficient of expansion.

Dowel for foam plastic

To install the dowels in the wall, pasted over with foam, holes are made of the appropriate depth, into which the dowels are inserted. They should be in the foam 1.5-2 mm.

Dowel holes

Fastening “umbrellas” is made by an envelope: at the corners of the sheet and in the center. Thus, for fixing each sheet you need 5 dowels. The dowels must enter the concrete base to a depth of 50 mm, into a brick wall by 90 mm. For example, with a foam width of 8 cm, “umbrellas” with a size of 13-17 cm are used. (more…)

Pillar foundation under the frame house do it yourself

The base is reinforced with 4 steel rods for 10–12 mm. Every 25 cm, they are intercepted by wire from the divergence of the bars to the side. The bottom of the formwork is cemented to a thickness of 15 –20 cm.

Before the cement mortar sets in, a core of the pipe is installed in its center, and a frame base with reinforcing rods from 2 cm from the formwork walls.

  Pillar foundation under the frame house do it yourself

The concrete solution of sand, gravel and water is poured, layer by layer, 30 cm each and made by the dense method of bayonet with a smooth reinforcing rod. When finished pouring, measure the level of the mounting horizon.

Alignment height is a mixture of the proportion of cement in the proportions of the 2nd sand.

Waterproofing and grillage

After removing the formwork column foundation with their own hands for a frame house is waterproofing ruberoid material. (more…)

Waterproofing basement walls from the inside

Cope with groundwater is very difficult. But, if the foundation is dry, it is quite possible that in the basement only a spring is trying to break through somewhere. In this case, raising the basement floor or underfloor to a considerable height will help to cope with the problem. This will also help if the groundwater does not rise too high.

A remarkable old-fashioned way is the construction of a so-called “clay castle” for protection against groundwater. It is envisaged at the construction stage and laid on the foundation. In our case, before filling and filling the floor, it will be laid with a layer of 40 cm only in the cellar.

1. For a “clay castle” device, the ground in the cellar or subfield is selected before the appearance of dampness and is replaced by clay. Use should be only the fattest, which will not miss the water. (more…)

The procedure for laying paving slabs

Laying paving tiles do it yourself

Tools for self-laying paving slabs:

  • Master OK,
  • hides order,
  • rubber mallet
  • steel or wood pegs,
  • level,
  • watering hose (must be equipped with a diffuser),
  • broom,
  • rake,
  • manual or vibration tamper,
  • profile,
  • high-quality cement, ranging from grade M – 100,
  • sand.

Technology laying paving slabs

The tile can be laid in three ways: on sand, crushed stone and concrete. Now we will briefly review the main stages of installation, and then move on to more general points:

We lay paving slabs on a sandy basis

  1. Pour sand layer 5-15 cm in the prepared box.
  2. Use a rake and level the sand.
  3. Pour water from a hose or watering can on this layer.
  4. Base tamp hands.
  5. Install the curbs using M100 liquid solution.
  6. Spill the prepared solution of the border board, as well as fill them with sand.
  7. Considering the peculiarities of the pattern on the tile, install the pavement, leave 5-7 mm gaps.
  8. Level the track with a mallet, if necessary, you can pour sand. With the help of the level it is necessary to control the slopes.
  9. Fill the gaps with sand using a brush. Move in different directions.
  10. Excess sand must be washed off with a weak stream of water.

Rack ceiling installation instructions

If the size of the room allows, the panel can be slightly bent, thus it will calmly go into both end profiles. The length of the panel should be more than 2 meters.

  Rack ceiling installation instructions

The second way. It is necessary to cut the panel by 1.5 cm, with one end into the end profile until it stops. Then the second end should easily go into the second profile. Align the panel symmetrically relative to the two end.

Holes in the panel under the lamp, diffuser and other elements are cut as follows. If the diameter of the lamp allows it to fit into the panel, then a circle of the required size is drawn at this place. Then along the circumference, an incision is made with a painting knife, and the resulting circle is divided into sectors with the same incisions. Carefully, separating by one sector by swinging, we will get an even hole for the lamp. (more…)

Preparation of the foundation for the house

Preparation of the excavation involves the implementation of a set of works aimed at bringing the adjacent soils to the required state in which their bearing capacity is sufficient to withstand the loads according to the project. The soil after all the work should tightly embrace the base of the foundation.

The main stages of land preparation for the foundation:

  Preparation of the foundation for the house

Formwork installation scheme for the foundation.

  • the formation of the pit;
  • cleaning the bottom of the pit (bulldozer);
  • base compaction;
  • soil moistening or drainage during compaction procedures.

Foundation trenches are usually digged by hand before the actual preparation of the foundation. Sighting of the surface of the base is carried out, the corners and axes of the walls are exposed with the help of pegs, the top is marked on the level. (more…)

Pouring the concrete floor in a private house

At the end of construction work related to the construction of the house, you need to take care of an equally important stage – fill the floor. To ensure reliability, durability and heat, finishing materials are used: concrete and wood. Each has a number of disadvantages and advantages that need to be taken into account when laying the floor in a private house with your own hands, as flooring is a crucial part in home improvement.

Tools and materials

The laying of the floor is carried out using the necessary materials and tools, a set of which must be prepared in advance. You will need the following construction equipment:

  • expanded clay;
  • roofing felt used for waterproofing the floor;
  • bounding corners;
  • trowels;
  • shovels;
  • reinforced mesh;
  • plastic film, also used for waterproofing.

To facilitate the work with concrete use vibrotamper, which densely presses the solution and gives it porosity. (more…)
