How to make a wood I- joist with their own hands - a step by step guide

Such support elements are widely used in the construction industry, especially in the regeneration of the different floors.On sale there are several variants of I-beams, which are used in the production of "clean" wood and wood based materials.The average price - 230 rubles / rm.- Quite acceptable for the majority of individual developers.

But there are several issues that suggest - but do not be simpler to manufacture wooden I-beams with his own hands?Firstly, there is not a problem with its transportation, secondly, with fitting on the installation site.It will have to be content with only the fact that the market offers.

How to organize independent "production" of wooden I-beams, which take into account - the theme of the present article.

explain to the reader some nuances I-beam manufacturing meaningless.For example, how to make their own hands grooves for mounting racks.Each master your tools (chain saw, milling or otherwise) and methodology.

But a few general observations plan will not be superfluous:

choice of material

concept timber - total.What exactly should be used in the production of I-beams with his hands?

Practice shows that it is better if it is glued (about its characteristics and advantages, see here).These blanks are least susceptible to deformation.If you read the various descriptions of the finished product, almost all manufacturers assure potential buyers that their system / material (among other advantages) do not absorb liquid, therefore, does not swell and does not rot.Even though far from this sphere man is well aware that no matter how treated wood, to completely eliminate water absorption impossible.

also important question about the breed.The author does not intend to engage in agitation, and offers only remember how our ancestors built.The most challenging part of any carcass - the lower crown.It had to be the most to protect from moisture.So always take larch for him.This tree, unlike other softwood, contains not only the resin, and special.It provides the material with unique properties.For example, when wet wood is just getting stronger.But what use - at the discretion of the home worker.

low-rise building practice shows that the most commonly used sizes of H-beams as follows:

remains to add that the minimum permissible cross section of the beam (mm) - 35 x 25. And this is only for the formwork.If you use I-beams such as an overlay, the workpiece have to be mounted as closely as possible, and this - the increased consumption of wood.Consequently, the timber is necessary to take a larger cross-section.

two main options - plywood or SALT.Although sales meet I-beams and other performances, for the manufacture of their own to better focus on these materials.SALT preferable, as they provide greater strength and durability thanks to a special structural composition and production technology.

Clay

As a rule, it is few people pay attention.Although all the glues differ from each other, including, and toxicity.Here it should be taken into account.When selecting funds need to become familiar with its structure, especially if the installation is supposed to overlap of the I-beams in a residential building.The recommendation is simple - the lower the "chemistry", the better.

Features of manufacturing an I-beam wooden

1. After preparing the boards they are made drunk for the subsequent installation of the rack.It should be positioned vertically, so special attention - the accuracy of marking (being the longitudinal axis of the workpiece).
2. Each plate is carefully inspected before use.The slightest flaw (and it will affect the carrying capacity of I-beam) - the reason for rejection.The edges of the selected plates slightly beveled to better samples included in the slots.
3. drank in the bars are coated with an adhesive composition;inserted into the lower rack, after which the superimposed upper and pressed.
4. assembly is left in a position to complete drying of the adhesive.This is the time specified in the instructions for use of the composition.

Qualitative dock all the elements of an I-beam segments can provide a similar sill length.They are superimposed on the bars and pulled together makeshift clamps (rope belts with carbines, and the like), to complete the curing adhesive.And only after that wooden beam, I-beam can be used for arranging the overlap.

process of making the supports of the timber, as well as the choice of materials, too much trouble is not.Work done by the hands, and save time and money.But it is justified only if the load calculations were performed on a professional level.If there is no certainty that it will make their own, not worth the risk.Slab - a critical part of any design and no economy can not justify the infringement of the design parameters.
