Hello, welcome to the officialwebsite of IronStar. IronStar will introduce you top 5 tips for purchasing ametal floor deck roll forming machine.
What is a metal floor deck?
The metal floor deck is a layer of galvanized sheet profiles wrapped with cement and steel bars between floors when used to build high-rise buildings. Its function is to bear the weight of cement and steel bars.
Metal floor deck is widely used in power plants, power equipment companies, automobile exhibition halls, steel structure workshops, cement warehouses, steel structure offices, airport terminals, railway stations, stadiums, concert halls, grand theaters, supermarkets, logistics centers, Olympic Games Steel structure buildings such as stadiums and stadiums.
The metal floor deck meets the requirements of the rapid construction of the main steel structure and can provide a firm working platform in a short time.
#1 Buying a metal floor deck roll forming machine should pay attention to the thickness of the floor deck
The flatness of the metal floor deck should be less than 3mm, and there should be no noticeable unevenness and distortion. The galvanized layer should be more significant than 120g/.
There should be no scratches, scratches, and residual Erbao welding slag. Solder joints should be firm. There should be no contaminants on the surface that would affect the setting of the cement.
Most metal floor deck-forming machines can produce galvanized sheets less than 1.2mm. Suppose your building requires that the thickness of galvanized sheet be more significant than 1.5mm. In that case, you’d better inform the roll forming machine supplier to prevent you from buying products that do not meet your requirements.
#2 The specification of the metal floor deck is worth your attention
The mainstream metal floor deck has two ribs, three ribs, and four ribs. The limited areas are 1000mm, 915mm, and 688mm.
The floor decking is divided into open deck decking, shrinking deck decking, and closed deck decking.
1) Open metal floor deck
Open metal floor deck, also known as open profiled steel plate, is an important supporting product for steel structure buildings. It is formed by the rolling and cold bending of galvanized sheet. It is mainly used as permanent formwork and can also be selected for other purposes.
2) Closed metal floor deck
The closed metal floor slab is to add a shear groove on the original floor slab surface, and through the effect of concrete wrapping, the two are jointly stressed, and the strength of the floor slab is increased. METAL FLOOR DECK can save part of the tension reinforcement.
3) necked metal floor deck
It is used as a formwork; in the normal use stage, it can replace the stressed steel bar. If the load is large, the stressed steel bar needs to be added; in the case of fire, the refractory steel bar needs to be configured.
You must ask what the reason for purchasing these metal floor deck roll forming machines is?
The back of the closed metal floor deck is a flat surface. The back of the open metal floor deck is a corrugated surface, and the construction is more complicated. First of all, the difference lies in the bearing capacity of the plate itself after forming. Secondly, after the plate is created in the closed floor deck, the bottom is a plane, which is convenient for secondary construction.
There are many types of open metal floor decks. The frequency of use in actual engineering construction is also very high. The core advantage of an open metal floor deck is cheap and cost-effective.
The amount of steel used for closed metal floor decks is relatively larger than that of open metal decks, so that the relative cost will be higher. Although there are many advantages, the actual use needs to be purchased according to the real situation of the project itself, so the frequency of open metal decks is Also considerable.
#4 Installation process of metal floor deck
The construction process of the metal floor deck is generally as follows: elastic wire → cleaning plate → lifting → plate layout → cutting → pressing → side welding → end welding → hole retention → plugging → acceptance → stud → reinforcement → Embedded parts → pouring → curing. Of course, so many processes are inseparable from a good labor organization. The Loading metal floor deck can also handle the following processes separately according to the actual situation on site.
Labor organizations are divided into two groups:
The first group is responsible for the transportation of materials, including clearing and reverse transportation, until the floor deck is hoisted to the construction site accurately according to the construction progress, including 5 hoists;
The second group is responsible for laying, including reinforcing bars, cutting, installing, and leaving holes. Each group of 3 people is responsible for an intersection, and 4 groups work at the same operation level at the same time. When tying steel bars and pouring concrete in the next process, a special person should be reserved to strengthen the maintenance of the floor decks laid.
#4 The advantages of metal floor deck
Metal floor deck is a very reasonable structural form, which can give full play to the advantages of steel tensile strength and concrete compressive strength according to the location and characteristics of its components.
1. As a permanent mold, the metal floor slab is easy and fast to construct, and there is no need to wait for time to remove the mold. It can be constructed in multiple houses at the same time, which greatly improves the construction speed, shortens the construction period, and reduces the cost.
2. The steel structure floor deck is lighter than the prefabricated floor slab, which reduces the load of the building, and has good fireproof and waterproof, thermal insulation, and sound insulation effects.
3. It has excellent mechanical properties. When used as a composite floor, it can partially or completely replace the steel bars at the bottom of the slab, reducing the production and installation of steel bars.
4. The floor deck building has less pollution and damage to the environment and high material recovery and reuse rate.
5. Lightweight and high strength, lightweight, and good toughness. The thin plate can even be covered in a curved shape, which is easy to construct and transfer and is not easy to be damaged.
6. The flat bottom and the small uniform joints make the bottom of the board very beautiful.
7. After the floor deck is installed, it can be used directly as a construction platform. Since there is no need to use temporary supports, it will not affect the work of the construction plane on the next floor.
8. According to the different section shapes of the profiled steel plates, the floor concrete consumption can be reduced by up to 30%. Reducing the dead weight of the floor slab can also reduce the beam, column, and basic size accordingly and improve the overall performance of the structure.
9. Various pipelines can be directly embedded in the board. The structural layer and pipelines are integrated, which indirectly increases the story height or reduces the building height, which brings flexibility to the architectural design.
10. In the construction stage, the floor deck can be used as the continuous lateral support of the steel beam, which improves the overall stable bearing capacity of the steel beam; in the use stage, the overall stability of the steel beam and the local stability of the upper flange are improved.
#5 The roller of the metal floor deck roll forming machine is the most critical part
Since all the raw materials of the metal floor deck are galvanized sheets, a large amount of galvanized layer will peel off on the machinery and equipment during the production process. If it is not cleaned in time, it will cause scratches and other damage to the galvanized sheet, and The version produced is not very standard. The roller is the core component of the roll forming machine, and its material determines the machine’s service life. The roller materials used by IronStar are all high-quality bearing steels, which are sturdy and wear-resistant and have a long service life, so you can purchase them with confidence.
