Over the period of time, the construction industry has seen many dynamic changes in terms of materials and equipment being used for construction of buildings, bridges, homes etc. The latest technologies are not only making construction works easier, but also safe and less time consuming resulting in faster construction timelines and better monetary savings.
One such technology that is making waves is precast panel installation, becoming an industry norm nowadays. For those not familiar with the construction industry, precast panels are made off-site by casting concrete into reusable form systems designed and shaped as per the specific site requirements.
Precast concrete panels can be made in any shape, size and colour and then transported to the site in large trailers. Precast panel installation is usually done using cranes. The panels are sometimes large in size and weigh anything from 1 to 10 tonnes. It is getting popular in the industry as it allows construction companies to control the quality and scale they make the panels.
Types of Cranes Used For Precast Panel Installation
Precast panel installation is primarily done with the help of cranes. Depending on the site and size of the panel, the companies may use different cranes such as a tower crane, mobile crane and crawler crane. Mobile cranes are very popular for precast panel installation. They can be used for short periods of even 1 day or for long periods as required. A mobile crane can easily do a precast panel installation of up to 350 tonnes.
Systematic Approach of Precast Panel Installation
The lifting inserts and clutches play a vital role in the safe lifting and installation of the panels during a precast panel installation. Lifting inserts are inserted into the concrete panel during the casting stage itself to aid the lifting and installation of the panels. As part of the installation equipment, lifting clutches that are compatible and designed as per the lifting inserts are also used.
Both the lifting inserts and lifting clutches are designed and manufactured by professionals who consider the size, type and weight of the precast concrete panel and the site of the precast panel installation. Any errors in the lifting insert and clutches could lead to the concrete around the insert coming loose and causing an accident.
Most construction companies make it a point to specify the exact lifting clutches as per the lifting insert and require a letter from the manufacturer stating both.
Few Words About Panel Bracing?
Another key factor for safe and sturdy precast panel installation is panel bracing. It refers to the temporary support systems set up during the installation to brace and hold the precast panel. It does not fall down or overturns due to its weight.
Before the precast panel installation starts, the panel bracing needs to be designed. Not only that, other vital factors such as wind pressure, the weight of the holding structure, design of the precast panels need to work correctly and safely. Otherwise, in case if there are any errors in its design could lead to the entire installation being a failure and even have fatal consequences in case of an accident.
Final Words
While precast panel installations save a lot of time and money, considerable detailing and safeguards must be undertaken to ensure a sturdy and safe installation. Potential on-site hazards can be avoided by taking all safety measures into account and using only compatible lifting inserts and clutches during the precast panel installation. Overall, the process of precast panel installation can meet your needs and give you complete peace of mind.
