Installation strapping timber and junctions. Forms, ways of installation technology.

Strapping beam plays the role of raft foundation on the pile, as well as on the pier foundation frame house. Bottom rail should tie together all the elements of the house, so it is a very important element, which largely depends on the reliability and durability of your frame house.

Strapping used bar section of 150x150 mm or 200x200 mm. The cross section of the beam must correspond to the thickness of the wall structure.

The requirements for piping

When installing strapping timber, observe the following requirements:

- Be sure to set the waterproofing in the junction elements to the foundation.
- When the timber must follow certain rules: timber should be made of softwood, lumber grade - first or second; humidity timber - no more than 12%. Timber should be smooth, with no chips, cracks or wane.
- all elements should be securely binding together and fasten it to the foundation.
- Be sure before laying the entire timber is processed retardants (part of fire), and preservatives (means of preventing contamination of wood fungus and mold).

 Fixing strapping timber to the foundation

- To fix the piping to the foundation of brick, concrete, apply the bolts. The process can be concreted foundation mounting bolts, which then is pushed beam. You can use another way: after the installation of the foundation Drill holes and install the anchor bolts.

- With metal piles piping fastened by bolts with a diameter of 12 mm. Bolts are twisted to the prepared holes in the top hat metal piles.

connection piping

Reliable connection grillage connections plays an important role in the strength of the frame house. The compounds are angular and in places build long bar along the wall. The methods of making compounds:

— "In the paw" or in a half-tree.
— "Dovetail" It is considered to be the most durable and leak-proof, but at the same time the most difficult connection. This work only by professional carpenters.
— In polulapu - a compound similar to the cut "dovetail".
— Sipovoie the compound is well suited for a corner.
— "Butt" - this is the simplest connection that is able to make even a layman. It does not have the necessary reliability.

additional fixing

For a more reliable connection parts tying the fittings are mounted with special elements.

- Staples diameter of 8 mm are mounted on top of the strapping. The bracket is driven in whole areas that did not drink for the connection. Score bracket is not as easy as it seems, therefore, required to comply with simple rules: first, the markup is applied, then sawed groove, which lies bracket, so that it does not interfere with the installation of walls, make a hole in the ground leg dives that followed processed. Staples must go to the tree is completely flush.
- corners for fixing timber should be made of steel not less than 2.5 mm thick, reinforced corner. Screws steel should be selected in accordance with perforated holes.
