Extension to the house - the nuances of the process

One of the advantages of home ownership - the possibility, if necessary, increase the usable area, was attached to the main structure further. So we will have residential or utility room, whom some functionality was not enough. To improve living conditions for extension owners, and are not organized on the problems, it is necessary to build on existing technologies, rather than on the principle of "like anything, if only cheaper." Therefore, we shall understand how to correctly attach to the house on the basis of common methods and experience FORUMHOUSE users.

Foundation

There are two types of foundations under the extension - tight coupling and expansion joint.

rigid Coupling

This connection is designed for nepuchinisty ground and justified in the construction of heavy structures in two or more floors, but only if the main building and have to defend the village. The new foundation should be of the same type as the base (tape, plate) and the same depth in view of possible shrinkage. A bunch of tapes made by means of valves, for which the foundation of the house dig up the entire depth, the work area is fraught with too much exposure of deformation.

Holes are drilled fitting in a checkerboard pattern in the fabric of the foundation, on the basis that their length 35 times the diameter of the rod, and the length of the valve is twice greater than the depth holes. Armature hammered into the holes in the further extending portion will fill with concrete to give a total monolith. Bundle of plates will be available at a thickness of more than 40 cm, and the presence of base plate protrusion 30 cm, for coupling the armature and discourage welded to the reinforcing frame of a new plate.

To perform a rigid coupling, it is necessary to take into account that the flooded basement, connected to the main, should stand, ideally - in the course of the year. If you can not stand such a life, it is better to use another method.

Expansion joint

The most common type of ligament - when filled fully independent about the old foundation. Particularly suitable for heaving soils for lightweight construction, seam thickness is from 2 to 5 cm. To connect the aesthetic foundations, and
suture in place by a docking same along the entire length of the board is used, or pre-wrapped polyethylene roofing material. Since the load on the ground is less drawdown will also be smaller, and the seam will enable annexe planned to "play", without affecting the integrity of the house.

During the construction joint between the walls is filled with insulation, and the seam itself subsequently sealed by elastic means or special closing nashchelnikami. One user has found interesting solution- lining of stainless steel, between which - a layer of corrugated rubber.

In principle, you can buy a "zakryvashku" for expansion joint, once properly insulate inter-wall distance, close it from the street "zakryvashkoy", and if over time is shrinking, compression or tension, "zakryvashka" compensates for this moment. A return to the rubber in the old form, it will be possible to unscrew the screws from the side of a bygone Drill and again, to new places in the bricks.

Since the foundation does not communicate with each other, under the extension you can choose any type, based on the characteristics of the soil and the intended loading. It can be slab (monolith or UWB), belt (MLF or deep freezing) or columnar (pile).

Portal users prefer to dock foundation is through expansion joint is the most justified and safe way.

Whatever was good (nepuchinisty) soil, if it's not a rock, it is necessary to wait for the shrinkage of the basement additional building to the main house. Accordingly, it is necessary to take measures to ensure that the shrinkage data, non-destructive structure and provide acceptable functional properties of the structure. Hence: annexe - in fact a new house next to the old and lightweight design, walking is permissible, and breaking of the horizontal floor and jammed the door is acceptable.

materials

Modern building materials market offers a choice for every taste and budget. The maximum demand today an extension of foam concrete, aerated concrete, cinder block and similar large-size varieties masonry and frame structures. Skeletons in the lead thanks to the construction of speed, relative affordability and simplicity, energy efficiency, they are not inferior stone buildings through the use of heaters.

However, as far as possible it is recommended to choose the material, similar to the basic: wooden extension to the wood home, etc. This is especially true for homes that are not supposed to sew with the same extension facade. If you plan to use the siding or cladding like, the choice is not limited.

Options walls ligament

Extension to the house can have four walls and three, while playing the role of the fourth outside wall. Four walls in the relevant annexes of masonry materials, a bunch of walls is not required, the right foundation and compliance level masonry give a smooth seam. Having the insulation layer between the walls, it allows the use of blocks adjacent walls of smaller thickness. When the sliding frame construction used cords: stuffed two vertical timber wall, between which the plant vertical bar extension.

Compound boards in the annexe

When the extension is collected from the profiled or laminated veneer lumber or logs, the wall with the house or connect with metal staples or special galvanized corner with a shelf of 63 mm.

Corners are put on the screws, leaving a small gap to shrink. The seam is closed in both cases, the panel strip or frames. Also docking bars in the annexe is carried out by tongue and groove system, the slots are selected in the supporting wall is cut at the recessed spike segments.

Roof

Extension is slid under the common roof, when a rigid connection, if the selected expansion joint structure is easier to cover separately by sealing the junction. Depending on the roofing material, the seam is closed apron stainless steel, of a width of 30 cm, or special decorative element.

mfcn:

Shrinkage additional building to the main house imposes certain restrictions on the arrangement of the roof. Therefore, in practice, make annexe with a roof type continued to be available to deliberately and reasonably.

Functional

Like building a house, before the erection of an extension is necessary to pre-determine the functionality, since different destinations requires appropriate construction procedures. If you intend to make a living rooms, a need to strengthen the insulation. For the boiler room, the bathroom or the kitchen at once laid communication. Simply change your mind and repaired a couple of plastic pipe in the wall, deciding that another bathroom needed and the freshly batter.

Legalization

Before the construction of the extension of the capital necessary to get permission. In the city it is engaged in the department of architecture and urban planning in rural areas - administration. You can build and without papers, but then when you try to sell, bequeath or donate the house with an extension, you still have the paperwork, but more difficult in court. In the event of a confrontation with neighbors, they can sue samozastroy and insist on the demolition.
