An extension to the house - the nuances of the technological process, the experience of users FORUMHOUSE

One of the advantages of private home ownership is the ability to increase the useful area if necessary, attached to the main design. Thus, residential or utility rooms are obtained, to which the functional is not enough. In order for the extension to improve the living conditions of the owners, and did not organize them problems, it must be erected according to existing technologies, and not according to the principle of "somehow, just to cheaper." Therefore, we'll figure it out how to properly put on the house, relying on the generally accepted methods and experience of users forumhouse.

Foundation

There are two types of the foundation device for an extension - a rigid coupling and a deformation seam.

Hard hitch
Such a compound is designed for non-empty soil and justified when erecting a heavy design in two or more floors, but only if the main building has already been sat down and the village. The new foundation should be the same type as the main (ribbon, stove) and coincide in depth, taking into account possible shrinkage. The bunch of ribbons is made by means of reinforcement, for which the foundation of the house is diverted to the entire depth, on the workstation too large degradation is fraught with deformation.

The reinforcement holes are drilled in a chess order in the foundation canvas, at the rate of which their length is 35 times larger than the diameter of the rod, and the length of the reinforcement itself is twice as much as the depth of the holes. The reinforcement is clogged into the holes, in the future the protruding part will sing concrete, it turns out a general monolith. The bunch of plates is possible with a thickness of more than 40 cm and the presence of a base plate of 30 cm, for the hitch, the reinforcement is chopped up and welded with the reinforcement frame of the new plate.

To fulfill a rigid coupling, it is necessary to take into account that the filled, associated with the main one, should be understood, ideally for the year. If there is no way to withstand such a term, it is better to use in another way.

Expansion joint
The most common type of bundle is when the old foundation is completely independent. Optimal on bunched soils for lightweight structures, the seam thickness ranges from 2 to 5 cm. To aesthetically connect the foundations, and
The seams in the place of the docking remained the same along the entire length, use boards, pre-wrapped with polyethylene or rubberoid. Since the load on the base will be less, the drawdown will also be less, and the seam will allow an extension to "play" planned, without affecting the integrity of the house.

In the construction of the joint between the walls, the insulation is filled with insulation, and the seam itself is sealed through elastic funds or closed with special nicknames. One of the users found an interesting decision-lining of stainless steel, between which - a layer of corrugated rubber.

In principle, you can buy such a "closer" for a deformation seam, immediately insulate the interconnect distance, close it from the closure street, and if there is a shrinkage, compression or stretching, "closer" will compensate for this moment. And to return the rubber in the old form, it will be possible to unscrew the screws with the left side and get it back, on new places in bricks.

Since the foundations are not binding to each other, you can select any type on the extension, based on the characteristics of the soil and the estimated load. It can be slab (monolith or UCP), ribbon (MZF or to the depth of freezing) or column (pile).

Portal users prefer docking foundations precisely through deformation seam, as the most justified and safe way.

However, if possible, it is recommended to choose a material similar to the main: wooden extension to a wooden house, etc. This is especially true for houses that are not supposed to stake the same with an extension facade. If it is planned to use siding or such a facing, the choice is not limited.

Variants of ligament walls

An extension to the house can have four walls or three, then the role of the fourth is played by the outer wall of the house. Four walls are relevant in the extensions from the masonry materials, the vehicle bunch is not required, and compliance with the level of the masonry gives a smooth seam. The presence of a layer of heaters between the walls allows the use of a smaller thickness for the adjacent wall. During frame construction, sliding ligaments are used: two vertical vertical vertices are stuffed, between which the vertical set of extension is hardened.

BRUSEV'S COMMUNICATION IN A TRANS

When the extension is collected from a profiled or glued timber or logs, the walls with a house are connected to either metal brackets or special galvanized corners with a shelf from 63 mm.
Corners plant on a self-tapping screw, leaving a small backlash on shrinkage. Seam in both cases is closed by asset or casing. Also, the docking of the bars in the target is carried out by means of a spike-groove system, the grooves are chosen in the bearing wall, the spike is cut on the embedded segments.

Roof

An extension is set under a common roof when a rigid connection is performed if the deformation seam is selected, the structure is easier to cover separately, sewing the place of the adjoint. Depending on the roofing material, the seam is closed by an apron of stainless steel, from a width of 30 cm, or a special decorative element.

Legalization

Before building a capital extension it is necessary to obtain permission. In the city of this city, the department of architecture and urban planning, in rural settlements - administration. It is possible to build and without papers, but then when trying to sell, to make or give a house with an extension, you still have to execute documents, but it is already more difficult through the court. In the case of confrontation with the neighbors, they can sustain on self-progress and insist on demolition.

For anyone who plans an extension, it is useful to explore the topic on the forum. Interesting and experience of the user of our portal in the subject. The article will help determine the type of foundation under the future design. And our video will teach you
