Wooden I -beam Balks: Technical Nuances of Construction Technologies

Here at "All about the Roof," we explore the complexities of building technologies. Today, we’ll concentrate on wooden I-beam balks and examine their technical subtleties as well as their role in contemporary construction methods.

Wooden I-beam balks, also known as I-joists for short, are an essential part of building floors and roofs. They are made of an engineered wood product that effectively uses materials while combining strength and stability. I-beam balks, in contrast to conventional solid wood joists, have a flange (top and bottom) joined by a web (vertical section), creating an "I"-shaped structure. Because of their optimized strength-to-weight ratio, they are lighter and simpler to handle while being built.

The dimensional stability of wooden I-beam balks is one of their main benefits. The structural integrity of the building is guaranteed by engineered wood products, which are designed to withstand shrinking, twisting, and warping over time. For floors and roofs to remain level and durable under all kinds of environmental conditions, stability is essential.

I-beam balk construction allows for additional design and installation flexibility. Architects and builders are able to create open and spacious interiors without sacrificing structural strength due to their uniform shape and predictable performance. This adaptability continues through to installation, where labor costs and construction time are decreased by efficient cutting and fitting.

Furthermore, there are substantial environmental advantages to using wooden I-beam balks. Engineered wood products are more environmentally friendly than traditional lumber because they usually use fast-growing, sustainable wood species. These materials support sustainable building practices by encouraging conscientious forestry and effective use of natural resources.

What is an I -beam, and what is the essence of the new construction technology?

I-beams are particularly well-liked outside of Russia, particularly in Canada and other European nations. Furthermore, they aren’t even available for purchase in some areas! Why? In light of global experience demonstrating the exceptional quality and dependability of this type of building material, how did I-beams fail to establish a dominant position in the home market?

The truth is that the authentic Russian soul of the master is accustomed to working with robust and dependable materials: massive, challenging to raise, and inspiring respect with a single glance.

It has also long been customary for the overlap to be constructed using substantial, heavy wooden beams or even entire logs—certainly not from "cunning" inventive constructions with a thin partition. It’s also another matter entirely that dependability is guaranteed by the same laws of physics here, which apply to both architecture and construction.

Currently, the majority of Russian developers are prepared to construct floors out of metal rather than just two planks and OSB. Despite the fact that these beams have many benefits!

What is the good Canadian method for building ceilings?

Let’s examine every benefit of using damaged beams as building material for the ceiling:

Advantage No. 1. Amazing strength

The beams, which appear to be quite fragile, are actually far stronger and more dependable than they would be otherwise because of the extremely well-thought-out design. The lower portion of the beam is stretched while the upper portion bends. T.e., we are not discussing a single, monolithic component that must simultaneously carry both kinds of load:

Advantage No. 2. Accurate geometry

The optimal geometry of the beams themselves is a crucial second point. They do not flex, they do not escape, they do not dry out, and they do not alter their parameters over time. Manufacturers claim that these beams will function in the same way as they did a year after construction, even after 100 years.

What does it provide? First things first: a perfectly level ceiling that makes it simple to install any type of flooring, particularly laminate and parquet. In actuality, you should be aware that standards allow for a maximum deflection of 3 cm when working with bars and regular wooden beams. You’ll notice this right away, I promise: the floor will simply "walk" under your feet. Furthermore, this won’t impact any floor covering (maybe the inexpensive linoleum).

Naturally occurring wood is alive, so it’s normal for it to compress, dry out, or, on the other hand, absorb moisture. However, the I-beams don’t change in size because they are already composed of glued wood with a particularly strong connecting composition.

Advantage No. 3. Comfortable weight

The next crucial point is that two regular workers can easily handle such work because I-beams are light enough to raise one of them on their own. What does it provide?

First off, you won’t require heavy machinery to raise standard metal or wooden beams.

Second, because the heavy beam won’t fall on his head, working at the height will become safer.

Thirdly, since there will already be an order of magnitude less load on the foundation, using impaired beams will save a significant amount of money. Furthermore, the savings are substantial when we consider that up to 50% of the construction budget typically goes toward a sturdy, dependable foundation that can support not just walls but also extremely heavy beams.

Advantage No. 4. Manufacturing at home

If you are aware of the proper parameters and units for an impaired beam, you can create one for yourself. Ultimately, you will save a significant amount of money in addition to having faith in the ceiling’s quality.

Advantage No. 5. Practicality in insulation

And now for the final enjoyable moment: the incorporated beams are particularly useful for the interstory floor’s insulation and the ceiling’s subsequent decoration.

The only negative aspect is that high-quality double-breed beams are supplied by companies in Russia; if you decide to buy them, it’s crucial that you accurately account for any technological flaws. It’s all about the future overlap, after all!

What parameters should there be a wooden I -beam of ceilings?

Most likely, you’re curious as to why the I-beam is given that name. In actuality, it is made up of two primary components that resemble the letters T put together. And Taurus is the name of a T-shaped beam in turn. This is the origin of this peculiar name.

What kind of beam is that in the section? Initially, this is a plywood or OSB blank that serves as the "ribs" of the stiffener. Additionally, the pre-milled groove in the beams has the desired shape. The beam’s height ranges from 140 to 470 millimeters, and in actual use, its deflection is fairly stiff. The most profitable beam is 302 mm high if we choose a project involving beams for typical cottage construction with the most popular spans up to 6 m.

The Nakorovsky beams were the first to be produced in Russia, and manufacturers today continue to use their names. Depending on the thickness of the shelves, they are separated into two series: thin beams and broad-shouldered:

  • Subtle edging beams of the NJ series. These are beams with 38 mm shelves thickness. Such are harvested to arrange the perimeter of the outer overlap, where the opening under the stairs or for other loaded places is needed. They are single -layer and multi -layer.
  • NJH and NJU series wide -heating beams. These are beams with a thickness of shelves 64 mm or 89 mm, specifically for load -bearing spans. As you know, in such places the load on the beams is the most strong.

Here is where the two episodes diverge:

We observe this very significant point. A dangerous misconception about how wooden I-beams for floors are calculated can frequently be found online. It states that calculations are made using the outdated Naskorovsky beam table. In actuality, however, there were no SNiPs for the I-Taurus at the time, and the snow load in this table was approximately 90 kg/m, which corresponds exactly to the Rostov region.

However, given that you are aware that the snow load in the Russian Federation’s northern regions can be significantly higher, using such data is incorrect today. Consequently, rely solely on the following table, which contemporary manufacturers have already assembled:

Additionally keep in mind that not every kind of impaired beam in use today is appropriate for a ceiling device. Take formwork rally beams, for instance.

How to purchase a high -quality I -beam for your home?

Double-bearers are constructed from valuable coniferous wood, such as that of pine or larch trees, under factory conditions. I’ll give you some helpful advice if you decide to buy pre-made I-beam wooden beams:

  • Paragraph 1. Pay attention to the seam: a small output of glue should be noticeable. This is fine.
  • Point 2. The neckline should be conical in the entire shelf, and OSB itself should be milling and inserted correctly.
  • Point 3. OSB should be shot every half -meter with brackets right in the shelf. This helps to maintain pressure before the glue completely freezes.
  • Clause 4. You have the right to ask for a product quality certificate and see if the desired type of glue is used – the one that is allowed for glued supporting structures.
  • Clause 5. Check if there is a protocol of testing of beam samples in the related documentation, their number of technical conditions and release.

Seem to be what superior I-beams ought to resemble:

The key here is that although regular wood still has some moisture in it, these beams have already been pre-dried. Additionally, the beam’s design makes it simple to drill holes in the ceiling for gas and water ventilation, sewage systems, and other necessities. This is a crucial feature when building a private home or cottage.

Regarding the adhesive compound, it should be noted that some Russian developers have long since given up ordering raw materials from smaller businesses in favor of acquiring foreign double-rotary beams. This has led to domestic production of wooden I-beam beams, however the final product’s quality is not always satisfactory. Furthermore, there isn’t much experience because Canadian technology is still too unique and hasn’t attracted many adopters in our nation. Because of this, creating a dioecious wooden beam by hand can occasionally be simpler; there are no complicated steps involved. And we’ll explain what and how to you.

How to make an independent beam yourself?

It will take you approximately a day to produce the first sample when you begin the independent manufacture of an overseas beam for your home’s construction, but the work will go much more quickly after that. Follow these detailed instructions for every step of the process:

  • Step 1. Buy OSB sheets 12 mm thick and cut them into equal parts.
  • Step 2. Next, you will need boards in which you need to make the “Lastochkin tail” cutter in the middle of the board, about 12-14 mm deep.
  • Step 3. Pour a special glue into the hole and insert OSB sheet.
  • Step 4. To quickly dry the site, just use the heater.

The most important thing is to never purchase recently sawed or unbearable boards because they can eventually become unprofitably lean themselves.

This principle is used to calculate the beam’s height:

  • For a sheet with dimensions of 2440 mm, the optimal step of the beams will be 305, 406, 488 and 610 mm.
  • For a sheet of 2500 mm, a rational step will be 312, 417 and 500 mm. But the double -rotary boobs with a step of more than 6 meters are no longer used.

Under factory conditions, the OSB sheet is glued into the shelf and the double-barrel beams are always milled to make them narrower. Thus, the wood and leaf fit together the densest.

Polyurethane or melamine glue is utilized for this purpose, and the sheet is clamped with clamps and further clogged every 20 cm at a 45-degree angle along its length. Each of these beams can be produced in no more than two hours, and installation can begin after six hours.

Using unique block stations, join the beams together:

How to prepare beams for installation?

At last, the most accountable phase! Long before your I-beams are installed in your home, you must precisely measure the spaces between the ceilings so that engineering communications can be installed later. You will undoubtedly work with electrical cables, plumbing pipes, and engineering systems. Here, it’s crucial to get everything straight at the outset in order to stop the ceiling from deteriorating later on.

Drilling holes for communications

And now we’ll also get almost to the crucial topic of correctly drilling I-beam wooden beams. It is a fact that this needs to be completed on Earth prior to installation. Here, it’s crucial to follow all the guidelines; otherwise, even tiny holes could cause the beam to weaken all the way across. The technology used in their production determines the precise location of the through holes in the ceiling beams.

Therefore, the holes in the double-rotary beams shouldn’t be larger than 40 mm. They can position them nearly anywhere in between the taurs, but no closer than 150 mm to the beam’s end or the supporting element’s support. Such holes should ideally be positioned directly in the middle of the shelves, rather than higher or lower. Additionally, a hole’s maximum permitted diameter is 10 cm.

Additionally, confirm that the spacing between adjacent holes is twice as large as the largest hole’s diameter.

Black mounting nodes with a wall

You can begin installing the beams safely if you have done the necessary preparations:

The primary points where the double-barrel wooden beams are fastened to the wall are as follows:

A contemporary option for structural support in residential and commercial buildings is to use wooden I-beam balks. Combining the durability of wood with the effectiveness of engineered materials, they are dependable and adaptable for a range of construction tasks.

The lightweight nature of wooden I-beam balks in comparison to conventional solid wood beams is one of their main advantages. They require less labor and take less time to construct because of this feature, which also makes them easier to handle and transport on-site. Even though they are lightweight, they have good structural integrity and can support heavy loads without sacrificing safety.

The process of layering wood strands or laminating veneers to create a robust, composite structure is the construction technology used to make wooden I-beam balks. In addition to increasing strength, this engineered design reduces the possibility of warping or twisting over time, which is a potential issue with solid wood beams.

Furthermore, plumbing and electrical wiring can be easily integrated into the beams themselves thanks to the ease with which wooden I-beam balks can be assembled. By removing the need for extra routing channels, this feature expedites the construction process and maximizes building space utilization.

In conclusion, using wooden I-beam balks as structural support during building construction is a contemporary and effective option. They are a favored choice for architects and builders who want to improve the longevity and efficiency of their projects because of their lightweight yet sturdy design and simple utility integration.
