Steel Anchoring

Steel Anchoring

TEKMETSAN supplies a detailed Anchor Bolt Plan with every metal building system. These plans show the building dimensions, the precise locations for anchor bolt placement, and the total number of foundation anchor bolts required in the structure. 

Anchor bolts are not just the connection elements between the steel and concrete surfaces but they are one of the most important element in a steel structure. Anchor bolts are responsible for the transfer of loads between the steel and concrete member.

Depending on when the anchors are installed, anchors used by Tekmetsan are classified into two categories;

1. Cast-in Anchors

These are the type of anchor bolts that are installed in place before pouring the concrete and are efficient in handling forces of high magnitude. Bolts are firmly held in place while the concrete is poured to maintain proper alignment and position.

The size and location of the anchors can be determined from construction drawings.

 In the below figure, you can see some examples of cast-in anchors.

2. Adhesive Anchors ( Chemical Anchors)
Adhesive anchors are anchor bolts that are placed in a pre-drilled hole, which contains an adhesive that dries and bonds to the anchor rod thread as well as the concrete.
Adhesive anchors, also known as epoxy anchors or chemical anchors, are capable of reaching high bond-stress values in relatively fast cure times.
Adhesive anchors are fully threaded rods that can be supplied in many different grades and finishes and can be cut to any length required for a given application.
How to install epoxy anchors?

Good installation is critical to performance. Here is the 5-step for the installation. 

1. DRILLING: Drill correct hole size and depth on concrete/brick/stone/masonry.

2. HOLE CLEANING: Blow out dust and clean the hole with brush, then blow out remaining dust.

3. INJECTING: Inject mixed adhesive from the bottom of the hole.

4. INSERTING: Insert and rotate stud/bolt/anchor/rebar/threaded rods into the hole.

5. HARDENING AND CURING: Time table refer to TDS. Don’t touch until full curing.

• All structural columns on a building must be anchored by at least four anchor bolts

• The placement of all actor bolts on the structure must adhere to the approved Engineered Foundation Plan

• All anchor rods shall be placed with their longitudinal axis at a 90-degree angle to the surface of the foundation

• A template (preferably steel) must be used to insure exact placement of anchor bolts in concrete.

Steel Detailing

Steel Detailing

Structural steel detailing has evolved as a critical engineering approach in the construction industry, requiring great precision. Even a minor mistake might result in a significant loss of time and money.

Steel detailing is an important and necessary step in construction of residential and commercial structures, factories and institutes. 

Steel detailing provides a communication that collaborates key stakeholders such as architects, contractors, fabricators, and others who are involved in the project at any level.

Creating comprehensive steelwork drawings serve as a guide for the structural steel detailing process.

What is the scope of steel detailing works at Tekmetsan?

Structural steel detailing entails the development of comprehensive drawings for our fabrication similar as plans, estimates, and other necessary reports and activities. There are two sorts of drawings we used in this process: shop drawings and erection drawings.

The erection drawings specify the placement coordination of each steel component within the structure and detailed dimensioned plans. It is the construction site steel erector who refers these drawings in the steel detailing process, in order to know how and where to build with the fabricated steel pieces. 

Included in the erection drawings are dimensional plans to identify the steel members, in addition to all work required on the site including bolting and anchoring.

Shop drawings on the other hand are more detailed. Each steel component, such as columns, beams, braces and purlins are meticulously detailed in the shop drawings. This describes how steel fabricators should make each component.

Component dimensions and sizes, bolting, welding, material specifications, and other details required for each component’s fabrication are all included in the shop drawings.

With its decades of experience, Tekmetsan is responsible for the design, strength, and integrity of steel constructions. For the fabrication and erection of steel members, structural steel detailing aids in the creation of detailed structural drawings, design plans, and a range of construction documents.

Steel detailing is a vital link in the project’s communication chain and to avoid any kind of misunderstandings during or after the construction process, providing a universal communication ground between the architect, general contractor, client and Tekmetsan.

With steel detailing, comprehensive shop drawings may include for each piece:
• Size
• Material description
• Required dimensions
• Surface preparation
• Bolting
• Welding
• Painting requirements
• Manufacturing conventions
• Special fabricating guidelines.
Traditionally steel detailing was carried out manually by pencils, rulers, templates of circles, triangles, drafters, drafting machines, etc. Later, these primitive methodologies were substituted by Computer Aided Designing (CAD), a specific software used only for designing in 2D and 3D which are nowadays integrated within a BIM interface.

Steel Helicopter Hangars

Steel Helicopter Hangars

Helicopters require the exceptional protection of pre-engineered steel hangars. No other building system guards helicopters and other aircraft as well as a durable steel prefab hangar.

Why Steel is the Only Sensible Choice for Helicopter Hangars?

To create the lift needed to fly, helicopters must be extremely lightweight.  The endless vibration of a helicopter in flight takes its toll on these machines. Consequently, helicopters require diligent maintenance— and heavy-duty protection.

Pre-engineered metal hangar buildings offer the best protection at the best possible price.

Tekmetsan metal prefab hangars are durable, waterproof structures for all types of rotorcraft, gliders, jets, and other aircraft. Designed to withstand mother nature at her worst, TEKMETSAN buildings promise built-in resistance to earthquake, fire, lightning, snow and wind damage.

Metal Hangar Buildings Benefits

TEKMETSAN helicopter hangars offer the benefits chopper owners appreciate most:

• Unobstructed space— TEKMETSAN hangars promise clear span, column-free interiors up to 45 meters wide.

• Towering heights— Choose hangars up to 12 meters at the eave height on a standard TEKMETSAN hangar design.  Even taller structures are available with additional engineering.  Taller hangars allow ample space for a variety of aircraft— and leave room for two-story offices, kitchen space, or pilot and personnel quarters.  Unlike arch shape buildings, TEKMETSAN hangars supply maximum usable space.

• Limitless lengths— Pre-engineered steel buildings and hangars can achieve any length required.

• Watertight protection— TEKMETSAN’s fasteners with built-in sealing washers, die-formed ridge caps, sealed eave closures, and formed-based trim keep the hangar dry in all types of weather.  

• Bolt-together system— No welding, cutting, drilling, or painting is necessary with a TEKMETSAN hangar.  Our pre-engineered system reduces the erection time significantly.  

• Bird-proof ceilings— Unlike truss-type buildings, TEKMETSAN’s rafter-and-beam portal frame buildings offer no place for birds to rest or nest overhead, fouling your chopper, equipment, or the crew!

 

Building a Hangar that Suits Your Specific Needs

Customize your helicopter hangar with stairs, overhead cranes, mezzanines, vents, gutters, or skylights and wall lights
whatever you need to make the building ideal for your helicopter or other aircraft.

steel and earthquake

Steel and Earthquake

There is a mistaken belief among some people that steel buildings do not do well in earthquakes. The truth is quite the opposite. In fact, steel buildings have a distinct edge over concrete in earthquakes. The reason, however, is counter-intuitive, and worth understanding.

We tend to think that the heavier and more rigid an object is, the stronger it is. This assumption is especially common regarding buildings, because our day-to-day experience validates it. If you’ve ever been in a wooden house during high wind, and heard the timbers creaking and groaning ominously, you might have wished the structure was concrete. We assume that the weight of concrete would help hold the house down, and the unbending nature of concrete would resist the swaying under the wind impact. That makes sense if the impacts are on the scale of a truck hitting a wall, or even a hurricane. 

However, an earthquake is different than other loads. It isn’t a surface force threatening to sweep the house off its foundation. The earth itself moves, moving the foundation of the building. It’s more like a strong bucking bronco, trying to shake the house off its back.  

Steel construction is lighter in weight than concrete, without compromising strength. It has less mass – and therefore less force – to damage itself under seismic shaking. It requires less earthquake resistance to be built into the superstructure and into the foundation, potentially lowering construction costs, too.

Moreover, steel makes a more resilient structure because it is a more ductile material, allowing it to bend considerably before breaking. It will respond better in an earthquake than a more brittle structure. In smaller seismic events, a steel building is more likely to snap back than it is to crack. Should the maximum seismic event for which the building is designed occur, there may be severe deformities, but it won’t undergo progressive collapse. 

Tekmetsan Steel Structures will meet or even exceed all local building codes including seismic codes. Let us know the location of your building and we will provide the ideal steel design for your building.
