Frame - design: simple answers to complex questions

Species classification frame structures of roof

There are a number of frame units, they are distinguished:

• frame roof rafter type - is generated from the timber, it is perfect for pitched roofs

• metal frameroof - is created from the beams, suitable for industrial buildings

• concrete frame - constructed of concrete slabs, used for flat roofing types

roofs of the timber are the most common in the construction of private homes.Popular in creating gable roof.Other species are not of interest for the construction of a house.They are not subject to review.

Varieties frame structure trusses

Frame construction is closely related to the rafter system.It is necessary to choose the right kind of truss installation.Load frame often falls on the rafters.For lasting hold load truss system is made up of wooden beams with a cross section of 15 by 5 centimeters.On the boards, and there is mounting frame installation, or crates.

Rafter installation are:

1. Hanging

1. Naslonnye

Both are used in the construction of a house.The difference lies in the ability of hanging rafters emphasis on mauerlat roof.This construction detail is the appearance of a piece of wood attached to the final number of laying load-bearing wall.Its production can be done with your own hands, you will need a timber with a section of 10 centimeters.

Upper edge of roof structures connected Ridge element (naslonnye rafters do not need a top-mount).

Installation frame structure depends on the type of the structure of the house, its features should be examined without fail.Need to know the intervals of external load-bearing walls.Gap more than 600 centimeters is not permissible to use in the installation of the hanging truss installation.Such cases provide naslonny version of rafters to the wall erected carrier.And metal can be used as the column support system.

Proper installation of the roof trusses allows no sag, and keep the quality at all the time of its use.

What building materials used for the frame construction?

Construction of the roof frame with his hands - a very laborious process.For it will require:

• beam of wood 15 by 5 centimeters to create Truss
• beam of wood 10 to 10 centimeters for mauerlat
• Wooden boards for crates
• Additional fasteners (screws, bolts)

also suitable auxiliary electrical appliances - drill, screwdriver, hammer, saw, measuring tape, chipping ax plummet.Special building materials do not need to simplify the process of preparing the carcass assembly.The main thing - to choose a high quality, dense, without the slightest damage to the wood.If possible, it is better not to save on quality.Solid wood will provide a long service life of the roof system.

Acquired pilosyre need to soak the protective liquid by means of eliminating the premature rotting of wood, the destruction of the structure of insects and more moisture.

Arrangement under the rafters of the roof frame

With self-assembling rafters need to procure materials dry structures are avoided damage during construction.Rafter installation consists of two legs and the lower base fixed to the him.It is connected to the legs by screws, anchor details.Rafter installation is mounted on a support beam.Such fixing means set the following:

1. Do in mauerlat several slots of a certain size to be connected to the rafters
2. Calculate the distance between the rafters - from one meter
3. If the roof exceeds height of three meters, use the vertical rafters

wooden crateWin-Win is the basis for the roof of the roof.Battens should be installed on a sturdy structure truss system.Rafters are fastened together the upper edges of the ridge member, the lower edges fastened strapping serving as a temporary member.During the construction of crates considered it a step plates, screws for fastening and screws.Step crates determined slope of the roof and its construction material.

Rafter installation has two designs:

• solid
• intermediate

Selecting depends on the roofing material.Plate, dense coating is applied to the rarefied crates.Soft roof requires a solid base (meaning tile, having the ability to rapidly deteriorate and sag, or roofing felt and similar materials).Metal tile, slate, galvanized layers easily applied at the intermediate purlins.Their undulating surface allows attached to the base with a rare step.It is important to make the payment periods batten boards and firmly fasten screws roofing material.

Importantly: Wooden houses and timber require additional protective treatment.She warns against moisture, fire and insect pests.To frame structure is firmly held, is to handle the wooden boards with antiseptic solutions and antipyretic (its composition increases the protective properties of boards under the influence of high temperature).Antiseptic warns of the emergence of insects and repels moisture.
