Bottom rail frame house - instruction , the construction technology

sill is called the very first layer of wooden beams (beams, boards), which is placed on the foundation and securely fastened on it.Lower installation needed to secure the future of building on the foundation and is the reference point for laying floors and walls.Only after laying the sill begins construction of a wooden log or frame house.

Bottom rail frame house

materials sill and requirements

waistrail traditionally made of wood conifers.The advantages of deciduous conifers:

• a straight trunk;
• high strength;
• durability and higher lifetime;
• wood quality and higher construction characteristics;
• reduced moisture permeability.

most widely used in the construction of timber obtained from such conifers, such as pine, larch, spruce and cedar.These materials need to choose the most appropriate for a specific site area (at a price, by the presence on the required strength and density) and then decide on the form of the timber.This can be:

1. timber;
2. board or a bunch of boards;
3. log;

Important!If a bunch of boards, they should be fastened together with nails or screws of different lengths in a checkerboard pattern.

With self-selecting the material and the cross section of material to select the sill should use special construction calculator that determines the calculation of the required parameters of wood.

to perform sill frame house chosen material must be processed:

• antiseptic - to prevent the development of mold and rotting;
• flame retardant - to improve the fire resistance and fire prevention.This is especially significant for the carrying out of such processing pine materials, as part of a timber includes a large amount of flammable resins.

In some cases, implementation of the sill used metal profile, but to build a frame object, the use of this material is not advisable.

Technology laying the sill to the frame house

Laying sill executed in several stages:

strapping sample on poles

Strip foundation

got the tape, and columnar During the construction of a frame house most widespreadtypes of foundations.Strip foundation is expedient to use in the construction of two-story frame houses, for the light and the single-storey buildings fit tab pier foundation.Fundamental differences in the preparation of different types of foundation under the sill there.Firstly, you need to check the levelness of the foundation.Second, to perform its waterproofing.As the insulating material used roofing material, roofing felt or bitumen.The selected material spread over the upper surface of the foundation, laying all the poles or the entire tape, depending on the type of foundation.

At this stage should provide a mechanism for bonding and binding foundation.What is the foundation or pierce wood cork, or mount anchor bolts.

Step 2. Preparation of construction material

building material chosen for the implementation of bottom stacking necessarily need to be dried.

then selected angular elements and their method of connection to each other.

Mix in a half-tree

Mix in a half-tree - with all selected items need to be cut or cut down half the thickness (as shown).

compound in polulapu

compound in polulapu - truncation of wood is performed at an arbitrary angle, but not a right.As shown in Fig.

easiest to perform cutting wood using elektrorubanka.

Step 3: Installation and connection piping

Once the waterproofing is laid and leveled, proceed to the laying of the material prepared for the binding.

Important!If you are using a bunch of board, it is placed on the edge.So that the connection between the boards is in the vertical plane.

start piping need to outline the future of the corners of the building.Take a point for the first external object angle and mark it (best to hammer a nail), then in the same way mark all other angles.After completing this step, you need to check the straightness of angles (you can use a carpenter's triangle).

The next steps will be the fulfillment of one of the corners of the future facility and laying all the prepared boards (planks, logs).The joints should be routed jute tape.

On the straights tying elements of the easiest to connect with each other head-emphasis (similar to the corner joints in a half-tree or polulapu), not forgetting to use jute tape as spacers.

between a stacking elements can bind metal corners or staples.

Here is the hardware boards using parts

After placing all the elements you need to re-check the straightness of all angles, and horizontal construction on the level.

As laid sill attached to the foundation?There are several options:

• Anchor connection - bolts must be pre-mounted in the foundation element in the lower trim bolt hole drilled at the stage of laying and fitting element.Anchor bolts should be in every post, which keeps harness or around the perimeter of the tape - tape at the foundation.
• Connection nails - nails driven into the place where the foundation walled cork wood.
• Connecting with klinevyh bolts - most strong connection method.

After fastening the strapping again you need to check its horizontal position on a level and you can begin to implement holes floor and wall joists.
