Enclosed balcony: step by step instructions

Enclosed balcony in a private home enlarges the living area and can make the architecture of the building more interesting and attractive.Balcony, quite a complex engineering structure and its extension requires compliance to ensure safety of the structure, compliance with fire safety requirements, etc.Any protruding architectural design on beams or cantilever slabs are built taking into account the rules of the strength of materials.

When deciding where to take into account the balcony line with the overall architectural composition and structural feasibility.Another important factor is the panorama view from the balcony, shaded or sunny spot lights.In the process of planning an extension to the house balcony Guide internal layout of the rooms and the convenience of access to the balcony.To annex the balcony on the first floor does not require special calculations.To equip the supporting pillars of brick or light strip foundation on which the plank floor and fixed the fence.

Regulatory requirements to balconies

When calculating the extension balcony on the second floor takes into account many factors: the thickness, material and age of the walls, design loads, taking into account the weight of the structure itself, the people present at the balcony, snow, etc.Depend on the dimensions of the balcony, the materials and method of installation of the frame.

• design load on the plate over the entire plane is 200 kg / m2, strip load - calculated based on a group of people standing along the parapet in the area 80 cm wide and 400 kg / m2;
• height of the balcony fencing not less than 105 cm under a load on the rail railing 30 kg / m2, and on the vertical rail 100 kg / m2;
• angle of the balcony slab from the wall to the edge of the capital - 2 °, to divert rain water (about 2 cm to 100 cm area).

addition to the above parameters to the calculated figures added 100% safety margin.Given the presence of a few specific nuances of the design of the balcony extension, easier to entrust the competent expert.

Construction balcony frames for private homes

Balcony consists of three main elements: a base, a protective fence and canopy.By attaching the base type balconies are divided into two types.Single-slab and cantilever-beam.

Balcony knee-clamped plate

During the construction of the box home, bearing wall is laid at least 40 cm concrete slab.The following series of construction material securely fix the balcony slab.Such structures are used in buildings with thick walls and heavy.The width of the balcony area should not exceed 1 meter.

Balcony on cantilever beams

Concrete or steel beams are placed in the wall during construction of the house of the box.Sometimes in the already erected wall Grooves and holes in them infest the beam to a depth of at least 40 cm. In this case, the balcony area is further reinforced brackets or supporting legs.The width of the platform is allowed from 1.2 meters to 1.5 meters.The support legs under the balcony allow you to increase the width of the site at 2 - 2.5 meters.

1. Concrete slab for the foundation of the balcony have a lot of weight and are set at the time of construction.For an extension to the house balcony wiser to use a cantilever-beam method with an institution in the wall of the metal sill and the deck of the wooden floor.
2. enclosures for balconies made of wood or metal.Various options are original wooden railing or metal grids can be purchased in a store or order in the workshop.In any case, the fence should be strong and have a secure attachment to be of sufficient height.Canopy performs the utilitarian function of protection from wind, sun and rain.For it is a metal frame and covered with roofing material.But if you approach the process of creative - the canopy will decorate the balcony.

frame for balcony device in the house

to install balcony base used channel or I-beam.Channel has a U-shaped profile, and the I-beam resembles a railway rail.For the balcony area 1.5h2 need 4 meters of metal girders 2 meter length.Channel cross-sectional 50h150h50 150h50h150 or I-beam with a wall thickness of not less than 5 mm, provided that the wooden flooring.

1. in the wall Grooves on par 4 holes to a depth of 50 cm with a span of 50 cm. The holes infest beams, if a channel, then the wide side up, aligned to the levels zabutovyvayutsya and concreted.Under the beams to the wall of the house is attached to the anchors 70x70 metal corner and grab a welded beams.This does not give the individual beams to sink in the wall of the house.The same is done and tying the ends of the beams balcony.Three of the metal strips are welded to the beams across the bundle, along the balcony area.
2. design for reliability under extreme frame beams are mounted struts.They are sealed separately from the corner in the form of a right triangle.Free triangle space is filled with beauty filigree ornament of a metal rod or a square.With the release of the balcony of the beam is 1.5 meters adjacent to the side wall and is welded to the side of the beam strut equals one meter.

support legs are mounted in metal tubes with a diameter of at least 2 inches.The upper end of the support section is put under extreme beams and fixed by welding.The lower part of the support column, anti-corrosion treated mastic is immersed in a pre-dug hole to a depth of 0.5 meters.Free space around the support compacted and filled with concrete.

Arrangement floor, fences and balconies overhang

1. Paul arranged for the balcony from a dry planed boards 30 - 40 mm thick.Boards are stacked wall to the edge of the balcony.End side planks are fastened to the extreme beams bolts, intermediate fastening can be done with screws.Is left between the boards minimum gap of 1-2 mm.No gap in wet weather may swell and heave the floor boards.The floor is covered with antiseptic and painted.
2. for balcony railings in the extreme points of angular welded two metal racks.Metal inch pipe a minimum height of 105 cm is fine.From the corner of the metal pipe is bent or U-shaped profile rails.To calculated the balcony of his size was 1.5h2h1.5 meters.The corner points of the railing are welded to the posts, and the final ends securely fastened to the wall.The wall is made of metal mortgages, which are welded to the ends of the rails.
3. Front and side openings of the balcony fences are closed decorative metal bars, wooden balusters, plastic panels, etc.
4. to pass into the studio ordered framework.The roof overhang can be made of galvanized steel, Makrolon, shingles or other roofing material.Mounted on the roof overhang on the bolts and screws.Fits canopy mount to the wall by 4 anchors (F16, L = 250mm, R cm = 30 kg / cm2) is enough.
