Prior to the 1950s, one of the biggest recurring costs in the construction industry was replacing concrete forms which had cracks and fissures caused by the ravages of age and stress. Cumbersome and costly, it had been a continual headaches that a lot of companies along with their clients dreaded. Pretty soon an experimental means of using concrete in the construction of bridges and buildings arrived in the form of pc strand, in hopes of reducing this costly and constant maintenance. Experimentation results in product development, and one of the most popular innovation survives to this particular day, the Hercules Single Strand Tensioning Systems.
The science behind producing prestressed concrete forms for construction purposes overcomes the material’s natural stress points and allows for utilizing it in construction without making use of reinforcement. Additionally, it permits more flexibility in the usage of concrete, enabling construction companies to pour and make longer spans of bridges, floors or beams that would ordinarily stop being possible without first using a costly network of reinforcing rebars and bars to act as load bearers over time. Its success utilized made it the most preferred choice for utilize in high rises and nuclear reactors everywhere, as a result of its stress reducing nature.
Tendons made out of high tensile steel cables or rods are strung throughout concrete forms made out of steel. By pouring the concrete to the forms, it forms around these pc strand along with their adjustable clamping devices to make a longer and thinner slab. Without all the joints related to using bars and rebars, the finished product is as strong, simpler to use for its reduced weight, and it has the weight bearing load points evenly spread throughout. When disadvantages develop in reinforced concrete, it generally begins with the joints of the pipes. With strung cables being stressed through the slabs, there are actually no joints with no possibility of future problems in flaws developing.
As the technology rejuvenated the development industry, especially when it arrived at building infrastructure sites like bridges, it was actually not completely flawless. Early stressing methods either manually drew the cables throughout the hardening concrete or maybe the cables were laid first along with the concrete carefully manipulated 61dexbpky and also over them, adding a great deal of manpower and labor hours to every single project. Anything they were initially saving in repair and replacement costs began to be eaten away in payroll hours.
Prestress Supply Incorporated developed among the first automated concrete stressing systems during the early 1960s, with only some companies in practice that were committed to developing this new technology, they soon became industry leaders and would remain dominant available in the market to the day. Their Hercules Single Strand Stressing Systems, as well as later innovations, operate on a design that utilizes low pressure hydraulics with jacks and chucks that distribute the tension cables faster and minus the shock gaps that can form with the manual pulling.
Recognized for decades since the stressing system with all the gentle touch, the most recent systems Hercules B and Hercules C will still be very user friendly and ensure the safety of employees utilizing it by letting them set the exact pressure needed around the cables and chucks to produce the worries network, eliminating tension snapping and harm to the delicate workings.
Built around an open-face draw system, the newer models make it simpler than in the past to change out cable, jacks, chucks and pulling jaws. In addition they feature the capability to switch strand diameters through the entire forming, while not having to completely restart this process, should your designs require it. A hundred percent mechanical in general, without electronics to short out, Hercules Single Strand Tensioning Systems are perfect to use in almost any environment or terrain. Even pc strand wedge anchor are now easier, considering that the systems allow workers to pull, form and install at your location with ease.
