Installation process, standards and norms for installation of precast concrete components

Installation of precast concrete components is increasingly commonly applied in construction with outstanding features "Super Flat surface - Super durable quality - Super fast construction" to improve the quality of works, sustainable with time. Join HRC Vietnam to learn more about the installation process, the advantages as well as the standards of product installation in the article below!

Construction process & installation of precase concrete components at HRC Vietnam

The process of construction and installation of precast concrete components is carried out quickly, efficiently and safely with 5 steps:

Step 1: Transportation gathered at the project

The component is transported to the base of the building

Post-production products that have been tested in terms of quality, qualified for warehouse export will be hoisted onto specialized transport vehicles and taken to the foot of the construction site waiting for construction.

Step 2: Exchange, unify the work, disseminate safety before the installation.

Engineers exchange, reconfigure work before installation

Before the installation, the engineer supervising the work will exchange and agree on the assembly process as required by the drawing, points to note, check the necessary accessories, installation tools, costumes, protection with construction workers at the scene.

Step 3: Measurement, pre-installation inspection

Technical staff conducting measurement and pre-installation inspection

Technical staff conducts inspection and re-measurement of the distance, certainty, standard height of the waiting foundation bolt system, the purlin / top bracing system has been prepared in advance according to the design plan between HRC and customers.  

Step 4: Proceed to build

Installation step

Precast concrete slabs will in turn be padded to the predetermined nail bolt position. After adjusting to match the bolt link between the concrete slab and the purlin/bracing system at the top, the worker will proceed to tighten the upper and lower bolts, fixing the installation position.

Step 5: Complete

Workers are conducting waterproof silicon coating

The gap between the two wall panels will be inserted with a foam gasket and covered with 1-2 layers of waterproof silicon. Next, the process of inserting anti-shrinking mortar into the bolt niche and completing the construction and installation process

Advantages of precast concrete components compared to traditional construction

Compared to traditional construction, precast concrete structures bring many outstanding advantages:

Accelerate the construction progress at the site, save labor power, construction labor costs

Currently, finding qualified, experienced and skilled workers in construction is increasingly difficult, having to spend quite high costs. This makes contractors who are applying on-site concrete construction have difficulty in controlling and monitoring the construction plan because the characteristics require a large number of workers, highly skilled.    

Meanwhile, the construction of precast concrete components mechanizes almost the entire process, helping to build quickly and accurately with the number of workers can be up to 10 times less and crane machines. Thereby speeding up the progress, saving labor costs, managing works, less depending on the qualifications and skills of workers

Improve the quality of the building, easily control from the influence of external weather factors

Installation of precast concrete components helps to improve the quality of works, accelerate progress, limit the impact of weather

Application of advanced precast technology from Japan, produced directly at the factory, precast concrete components are strictly controlled in terms of quality, bringing many outstanding advantages such as waterproofing, fire resistance, extremely good insulation. It help improve the quality of industrial factory construction, minimize the effects from weather and climate compared to when implementing construction at.

Construction and installation of precast concrete components to save resources

Because of the precast characteristics, the product helps reduce the volume and cost of necessary materials at the works, do not fall off materials, save waste, reduce 10-15% of the total cost of the works.  

Flexibility in construction

Construction of precast concrete components brings flexibility in construction, can be used for many works of diverse scale and structure, short and simple construction time, is a highly effective solution for industrial factory works as well as commercial works: residential areas, high-rise buildings, hotels, restaurants,...  

Eco-friendly

Construction of precast concrete components can limit the use of scaffolding, do not drop materials as well as limit construction waste and dirt from mixing activities, using plastered mortar. Thereby keeping the building clean, neat, environmentally friendly.   

Precast concrete component installation standards

According to TCVN 9347:2012, through the results and evaluation of experiments, the installation of precast concrete components should meet the standards of durability, hardness and crack resistance. Such as:  

Common standards

Crack resistance:

• No less than 90% when experimenting with two components.  

• No less than 85% when experimenting with three or more components.

Product life:

• No less than 95% if the two-component experiment is tested.  

• No less than 90% if the experiment is of three or more components.  

Hardness of the material: 

• No more than 115% when experimenting with two components.

• No more than 120% when experimenting with three or more components.  

Standards of each component

Roof structure: Roof structure must have a light load, convenient in installation. Anti-leakage and good insulation are two extremely important factors for industrial factory structures, especially in the hot season.  

Wall components: Reinforced concrete walls or brick walls are all qualified. However, at the present time, the wall is chosen by more people because of less effort and cost savings. Wall panels measuring 250 x 1200 x 6000mm are the most trusted by many people.

Floor beam structure: For floor beams, when constructing it is necessary to ensure that it is not affected by the weather. Any sudden temperature change causes floor beams to change substance, not maintaining the quality of the work.

If you and your business are looking for a quick construction solution, saving labor while ensuring the quality of sustainable works, installing precast concrete components at HRC is the optimal solution.
