PANEL VẬT LIỆU XÂY DỰNG MỚI – PANEL LÀ GÌ

Currently many customers may always ask, What is a Panel?, when receiving brochures, holding in hand but the question What is Panel, always in the mind of customers. So what exactly is Panel? Panel is a new and modern building material applying French technology. With scientific structure, has good load capacity, suitable for construction of high-rise buildings, or expansion and renovation of houses. Currently on the market Panel is a lot of customers as well as investors of the works interested and selected. In this article, we will answer more deeply questions about the question, What is a Panel?And why should you choose Panel for projects in the near future? https://vstoriginal.com/keyscape/
What is Panel? Panel is a type of floor with a simple structure, assembled by bearing beams and prefabricated hollow blocks of low weight, so there is no need or only very little use of formwork or columns during construction. . Panel floor construction time is fast, the floor construction is neat and clean, minimizes the use of loose materials, so it avoids dust and environmental pollution, the cost is much lower than that of the on-site concrete floor. No need to use formwork or scaffolding during construction.In particular, the roof deck can be used immediately after construction and can be continued to the floor immediately after the floor is poured.
Panel Floor Texture.

Panel Floor System is structured by PPB beams and floor Block pellets, with high advantages: the combination of load-bearing capacity of prefabricated high-strength prestressed concrete beams with sound and heat insulation. and has a small weight due to the hollow structure of the floor block and the coated steel mesh concrete layer, creating a perfect floor system.
Currently, large urban areas and high-rise buildings are springing up all over the country. In order to keep up with the development trend, many construction businesses are increasing and moving towards the use of new materials to save costs, increase construction progress while still providing quality and aesthetics. , suitable for the economy of many people, as well as the design trend of a modern house.Panel floor is one of the new materials applied with French technology, which has many outstanding advantages compared to traditional concrete floors. With a scientific structure, the Panel floor has a good load-bearing capacity, which is very suitable for construction of high-rise buildings, or expanding and renovating with houses with weak foundations.
Why should you use Panel materials in construction projects?
first: using panel floors helps investors, or homeowners save costs compared to the total estimated cost if using old-fashioned concrete floors.
Because when using the Panel floor, the construction time will be shortened, and the reinforcement of the foundation will also be “reduced” or not required.And the reason this type of concrete floor can do that is thanks to the following characteristics:

Panel floor is constructed by assembling Blocks into prestressed concrete beams, no need to use formwork, so there is no need to pour and wait to dry like the old-fashioned concrete floor. According to calculations, the time to complete the super light panel floor is 6 times faster than the old concrete floor.
Because the Blocks are cast with lightweight materials, the ultra-light panel floor is much smaller than the old-fashioned concrete floor. Therefore, using panel flooring does not need to reinforce the foundation while ensuring maximum durability. Specifically, the finishing unit price of this type of concrete floor is 20% cheaper than the old-style concrete floor.

Secondly, based on the compact characteristics of the panel floor material, construction can be carried out even in areas with complex and dangerous locations. Meanwhile, with the old-fashioned concrete floor, because it has to move a large volume of stone, sand and cement, the construction takes place very difficult.

Third: Panel floor has excellent bearing capacity, heat resistance, noise stacking. These properties are largely attributed to the materials used in the casting, and the porous structure of the Blocks.
Based on these outstanding advantages, it can once again be affirmed that panel flooring is a new type of concrete floor with high applicability and the ability to bring great benefits to users.
This type of ceiling is also especially suitable for architectural works in Vietnam when our country is in the stage of economic development and the construction of high-rise buildings, as well as the repair, expansion and renovation of buildings. Home is more popular than ever.
Panel Floor Evaluation Standards.

What is Panel? Panel is a material researched and put into use by leading French engineers in France and many countries around the world. In Vietnam, we are also using Panel under the supervision of leading engineers in the field of Panel construction and always comply with French technology:

Panel flooring in construction has been certified: CCBA 68, NFB14-305, NFB13-032 for the effectiveness and safety of the French Republic and has been approved by the agency of the Ministry of Construction of the Socialist Republic of Vietnam. and switched to construction standards in Vietnam-TCXD 235-1999.
Consists of beam systems and panels of ultra-light members.
General materials include: steel and concrete mix.
For PPB beams, the sides have a roughness without pitting with a diameter and depth greater than 2mm, the side faces are rough for adhesion; there are no transverse cracks in the longitudinal ribs of the beam. The curvature of the beam is L/500.
For concrete blocks, the outer surface must have roughness, deep roughness, 1-3mm wide, without impurities such as grease, paper, bamboo and other impurities. other.
With the thickness of the concrete layer protecting the prestressed steel of PPB beams, it is manufactured according to the standard design.
Depending on the design size, the regulations on the form of joints, bracing, slotting, supporting beams, reinforcement, concrete spreading of beams, floors and roofs Panels are constructed according to standards and construction methods according to standards. Standard 235 of 1999 of the Ministry of Construction.

What are the steps for the construction of the panel? How to make Panel Floor effective in construction and in the process of using later?
Using poles whose height can be adjusted to support the floor slabs, these poles must be supported against the beams forming right angles. When choosing the distance between the rows of support trees, it is necessary to pay attention to the buckling points of the panel. The panel is reinforced with the necessary things to be ready for the floor:
+ Reinforced iron bars at the bottom (underside).
+ Mesh panels connecting the bottom (on one side).
+ Iron handle is reinforced U-shaped at the support positions (wall head).
Construction Floor Panel.
Construction Floor Panel.

Tally Prime Crack panels are placed by hand and fastened with zinc. To prevent the slab’s top from cracking on unloaded walls. Panels must also be tied to the nets connected to the top. Furthermore, in place of support must be reinforced with iron for the Panels on top of the internal load-bearing wall.
After the panels have been arranged, the iron must be reinforced at the upper positions of the load-bearing walls to create continuous strength for the floor slabs.
At least 2 iron rods Æ 8mm should be placed on all outer edges (ring beams) as final reinforcing elements after the Panel floor is completed.
3D walls without concrete will not be able to withstand vertical forces, so all loads of the panel floor must be temporarily supported. Floor panels cannot be placed directly on the Panel walls. The moment of a standard Panel (100mm EPS, mesh coated Æ 3mm / 50mm / 200 steel bars Æ 3.8 mm per m2) is confirmed by the following tests:
+ Assume the top layer of concrete is 50mm with a dynamic load under the gathering condition of 1.50 kN/m2, the theoretical floor span is about 3m for the standard panel. In fact, it is recommended to choose the distance between the brace (support) to be 1.6m and 1.80m due to the buckling. In this way, the support plants are arranged at about 50-60 cm away from the wall panel. Thus, we can use tripods and easily when spraying the first layer of concrete for the wall panel, there is no floor protrusion or the protrusion cannot be tied to the wall panel, it is recommended to arrange a distance the supporting trees are 1.50m.
+ As soon as the concrete on the floor and walls is hard enough to withstand light loads (1 or 2 days), we can remove the support at the edges and increase the distance of the supports up to 2.25m . However, it should also be noted that before moving the support trees, in the areas of reinforcement in place of support (bearing wall head) at least the first concrete layer with a width of 50cm and below floor plate to ensure the connection between the panel and the reinforced iron in place to support from the beginning, only then can the load be accurately transmitted to the wall.

According to the above comments, the rows of trees depend on the thickness of Panel 100mm EPS and Panel 50mm EPS. The distances shown here are for Panels with 200 truss bars per m2. In this case the distance depends on the deflection and not on the buckling resistance of the Panel. If the Panel floor has 100 truss steel bars per m2, then the anti-buckling is important, so the calculation of the distance of the supports must be based on reality and the distance will be smaller than the distance of the supports for the panels of 200 steel bars. truss per m2.

Important things to note with Panel when constructing works:
How to install Panel to make floors in the house.
Note when constructing Panel Floor.

– Floor panel: used as indoor floor with a thickness of 160mm. In which, the thickness of beams and bricks is 120mm, and 40mm is the thickness of concrete on the brick layer (concrete grade 200). Regarding requirements, to ensure absolute durability, users need to keep in mind the following important bullet points:

+ Because the surface of the panel floor must always have moisture, after finishing pouring concrete about 1 day, we have to water regularly. Especially in areas where the surface is ventilated, or exposed to direct sunlight.
+ After 2 to 3 days (in cold weather conditions for at least 3 days) pouring concrete can walk or do light work. In addition, the material should be avoided to pile up on the surface of the ultra-light panel floor.
Because there are usually small gaps between the beams and the bricks from 5-7cm, with the underside of the super light panel floor, before plastering we need to use a small trowel to plaster the gaps first with cement mortar and then proceed to plastering. whole ceiling.
+ The time to unload the poles in the house is from 3-5 days. As for the unloading time with balconies, umbrellas is from 7-10 days (depending on the length of the race). Super light panel floor and notes on how to use it during construction.
+ If making a flat ceiling, the thickness of the mortar layer only needs to be about 5-7mm.
+ With the surrounding formwork, it is possible to unload within 1 day of pouring concrete.
How to build Panel to make the roof.
+ Similar to the construction of indoor floors, first of all, in terms of size, the thickness of the super light panel floor is usually 170mm. In which, the thickness of beams and bricks is 120mm, while the thickness of concrete on the brick layer is 50mm (concrete grade 200).
Other specific requirements are as follows:
Maintain moisture by watering regularly.something, after pouring concrete 1 day, it is necessary to build 100-high bricks around the roof and then proceed to pump water for the floor with a height of 5-7cm. Proceed to mix cement with water at the rate of 4kg XM/1m3 of water, stir well, stir once every 3 hours.
+ If the super light panel floor appears water-permeable, proceed to add more cement to that position, stir well to seal it (in case it cannot be handled, call the construction team immediately).
+ After soaking in water for 3-5 days, check that the roof is impermeable and dry, we proceed to drain the water and then proceed to lay a layer of nem leaf bricks (20×20.1.5) on the roof to cover the concrete layers. exposed to direct sunlight on cracked or leaky tendons.
+ Construction of plastering ceilings as for indoor flooring.
