Product Description:

DUOWEI steel bar truss floor deck is the integrated fabricated formwork for which steel bar is to be processed into steel bar truss and then the steel bar truss is to be welded with galvanized profiled sheet. In the construction stage, the steel bar truss floor deck can bear the construction load; moreover, concrete can be poured after steel bars are directly laid on the beam for simple steel bar works. As form functions can be completely replaced, form erection and removal works can be reduced, so floor slab construction efficiency can be greatly improved.

DUOWEI steel bar truss floor deck has features such as economy, convenience, safety and reliability, etc and it has been widely used by structure and building fields such as multilayer workshops, multilayer, high-rise and ultra-high steel structure buildings and various irregular floors, concrete structures and high speed railway, etc.

1. Unique double folding design
Effectively increase board edge strength; hard to bend or deform during transportation and construction;
Ensure edge straightness of product, fastening of bottom form gets easier;
Improve compactness of bottom form lapping, effectively prevent leakage;
Improve construction quality and protect customer’s interests.

2. Improved form spot welding technology
Original form spot welding equipments are improved to make welding current of many welding heads more balanced and stable, so the floor deck to be made will be free from cold joint or weld penetration phenomenon.

Four advantages

Economic
The load-bearing mode of the truss is reasonable, the consumed materials economic, and the advantage of integrated costs obvious.
It can be designed into two-way slab, with adjustable truss height and diameter of reinforcement, intended to apply to the floor slab of larger span.

Convenient
The field steel binding quantity is reduced by 60% - 70%, and the construction period is further shortened.
The load-bearing mode of the truss is reasonable, which can provide greater stiffness to floor beating slab, greatly reducing or even sparing the use of temporary bracing.

Safe
The mechanical property is basically the same as the traditional floor slab, with good crack resistance.
The fire-resistant performance is equal to the traditional floor slab, superior to the profiled steel plate composite slab.
The bottom die is not loaded in the use phase, eliminating the consideration to fire and corrosion problems.

Reliable
The reinforcements are arranged uniformly, and the spacing between two layers of reinforcements and the thickness of concrete cover are reliably guaranteed.
The two-way stiffnesses of the floor slabs are similar, conducive to the seismic stud welding, so the quality is easier to ensure.

Q:Will the sheet metal processing bending coefficient and plate thickness, bending angle
The bending factor and the thickness of the material you said bending angle ah bend the radius and bending the bending machine up and down mold, the length of the bending parts are related We are using experience value. After all, conventional standard brick algorithm does not take into account the equipment wear and tear, sheet material thickness of the situation Different thickness determines the different bending factors such as 1mm cold rolling fold 90 degrees and 2mm cold rolling fold 90 degrees Our actual situation is 1mm coefficient is 1.8 2mm coefficient is 3.5 The same angle 90 degrees is a bending factor of 60 degrees is 1/2 of the bending coefficient of 45 degrees is 1/3 of the bending coefficient of less than 30 degrees according to the different thickness of the buckle or buckle a 0.5 Material and plate thickness as different materials, the bending coefficient is different The bending radius is related to the bending machine. The standard single V or double V is even the default value of the other V slots. But there are customers who need to be too small or a large bend radius will be specific to the analysis Too small bend radius, our approach is to plan the groove to bend, so that the bending radius is very small, almost vertical right angle bending Too large bending radius, the upper mold can be used on the corresponding arc on the mold (note that the upper arc of the R is the inside of your bending R, if the outside R according to the outer R minus a plate thickness to determine the model) Or a large R30 50 or more, you can use a split bend, which requires the calculation of the cut-in angle and the last knife angle, as well as the size and angle of each knife There is a part of the length of this I think a lot or machine equipment and related to our machine a long time 1.5mm stainless steel over 1m according to the case will not use 8mm mold bending
Q:There are usually several kinds of plates
Cabinet box board usually has three kinds of materials: (1) Blockboard (2) Particleboard (3) medium density fiberboard And the surface layer of the board used in the cabinet cabinet is treated with trihydroxyammonium refractory veneer. Box thickness 18mm. (Avoid using 16mm, so as not to bend deformation, in the purchase of cabinets, please pay special attention). Blockboard wood core is made of natural wood sticks, the waterproof and moisture resistance is better than the particleboard and MDF. Because it is natural wood, so fast, easy assembly and easy to loose. In view of the blockboard is made of wood. Therefore, the surface roughness is often poor, often appear ribs block, for the cabinet cabinet board, the visual level of the feeling of uneven. Therefore, the cabinet company is not unreasonable to abandon. Such as blockboard to solve the uneven shortcomings, can be described as the ideal selection. Particleboard is fundamentally different from the traditional concept of particleboard. As a result of the use of German machinery, molecular shrinking more closely, so it can be load-bearing, and not easy to bend deformation. Particleboard is natural wood crushed into granular, the pressed into a plate, the waterproof performance is better than the MDF, cabinet cabinet is the main material. Which made the Jilin Lu Shui River board for the best, but there are many fake on the market, we must pay attention to the time to buy identification. Medium density board is powder after molding, resistance to wet performance is poor. Flatness is better, usually used for plate furniture, office furniture more. As the MDF tightening after easy loose, loose and then tightening strength. Therefore, the cabinet company has no more general use of some truth. Due to the medium density flatness, for the door and the countertop more appropriate. For the cabinet board, in the assembly fastening process, subject to certain limitations.
Q:Just bought a melamine plate wardrobe furniture, may be harmful to the human body? Will there be formaldehyde, benzene and other harmful gases volatilize it?
Whether the furniture is environmentally friendly is to see the amount of formaldehyde release if the house of the big taste, then you buy some plants placed at home diligent windows
Q:Is the PS board not an acrylic board?
Can be detected under, is not belonging to the acrylic sheet.
Q:Matt sheet and high light plate difference
My home is to use a paint-free board, its surface is a layer of broadcast film, a kind of plastic things, the surface of the speaker useful to this material, this panel is easy to be painted, and can not repair, it is thin, bad. But not easy to deformation, and no paint, no paint taste, relatively environmentally friendly, but inside is a thin MDF, not durable. Easy to mold, my home on the mold, especially the wet weather.
Q:Glasses and plastic glasses how to distinguish
There is a metal core in the mirror legs of the plate, and the plastic is certainly not there; there is the mirror of the mirror by the other end of the screw, it has cut the texture; there is the plate of the nose is sticky, What can be separated out
Q:Ask: PB, MDF plate is generally what is the quality of good or bad?
MDF Particleboard (PB)    Now many of the furniture industry is MDF board, because he has a lot of similar nature with the solid wood, the advantage is that it is much cheaper than solid wood.    The PB board is generally less than the MDF plate because it is rough and the edges are not flat. But the price is lower than the MDF, the strength can also be, that is, the amount of methanol will be more.     If you do the cabinet is topical, just used to put the tool (iron or other), I think the PB board can be considered. But if your cabinet is used indoors, it is recommended to go through the painting.     In addition, if your cabinet is used to put water-related, it is recommended to use MDF board, because it is more water-resistant than the PB board, after the water is not easy to deformation. I am glad to answer the question of the landlord if any mistakes please forgive me
Q:TR-90 cp pc plastic glasses frame difference, as well as what is the material sheet! Physical properties how?
TR90 spectacle frame surface lubrication, the density of 1.14-1.15, on the saline will float, than other plastic glasses frame light, about half of the weight of the plate material, nylon material is 85%, can reduce the bridge of the nose, the burden of the ear, suitable for young people . It is very resistant to wear, good chemical resistance, solvent resistance, weather resistance is good, not easy to burn, high temperature. And it is memory of the polymer material, anti-deformation index 620kg / cm2, not easy to change because TR90 material Eyeglass frame elasticity, toughness, easy to break, strength, no rupture, so it has sports safety. And it is very resistant to impact: more than 2 times the nylon material, ISO180 / IC:> 125kg / m2 elasticity to effectively prevent In the movement due to impact on the eye damage. No chemical residue release, in line with European food-grade materials requirements. TR90 material than other pc, cp and other frames material is much more expensive, and the production process is also more stringent, so TR90 glasses frame price than the other to be several times more expensive. CP: refers to propionic acid frames PC: refers to the plastic frames, made of polycarbonate Material: The material is made of high-tech plastic memory plate. Ingredients: Most of the current sheet metal components are acetate fiber, there are a few high-grade frame is propionic acid fiber, while the acetate fiber sheet is divided into injection molding and pressing Type, injection molding is the name of the mold is made of water, but most of the current is to suppress the processing of sheet metal glasses in terms of the origin of the plate in France and Italy, the plate is better, Japan is also quite good, many high-end sheet glasses Based on these high-quality sheet, and therefore more reliable quality.
Q:What is the difference between a sunglasses or a sheet of plastic?
Remove the sunglasses lens quality factors, the greatest impact on the price of sunglasses should be brand value-added and material caused by the different costs. Brand value added here is not discussed, this thing in the selection of sunglasses when the wise, can not tell a right and wrong. Then we talk about the material of the sunglasses frame. Compared to other materials, the use of sheet and plastic sunglasses frame on the surface is not see the difference. First of all, the plate frame is a memory function, if you buy the sunglasses mirror legs for you too tight or too loose, then you can adjust the mirror legs, straighten the bend is not a problem, but also inside and outside the bending Adjustment. If it is a plastic material sunglasses frame, a small adjustment does not work, it will automatically change back to the prototype, if a substantial adjustment - it will not change back to the prototype, because it has been broken ... Secondly, from the details, the frame of the frame to wear more comfortable, the basic will not appear discomfort. The plastic frame in addition to the overall structure is relatively stiff, is not conducive to the adjustment, the external paint may also be processed, there will be irritating smell. Finally, the frame of the frame will have steel (think of reinforced concrete, there are wood), durable. Plastic frame it, in addition to plastic or plastic, can be used to know how long days. So look at the appearance, you can not find the difference between these sunglasses.
Q:What are the main types of office furniture?
Common furniture with the plate varieties are: solid wood, fiberboard, particleboard, blockboard, plywood and so on. At present, the manufacture of office furniture is mainly used are: fiberboard and particleboard. Low-grade office furniture generally use particleboard, and medium and high-grade office furniture generally use fibreboard. Fibreboard is divided into high density fiberboard (density> 0.8 / cm3), medium density fiberboard (0.5 g / cm3 ≤ density ≤ 0.8 g / cc), low density fiberboard (density <0.5 Gram per cubic centimeter). High density fiberboard due to high density, difficult processing, and easy to nail, the installation of accessories burst; and low density fiberboard due to low density, large gap between wood fibers, easy to water swelling, resulting in surface cladding off, and even the plate disintegration, so the second The use of office furniture are less. The MDF (medium MDF), with the surface smooth, the internal structure of fine, good processing effect, with strong resistance to deformation and load-bearing capacity, And the plate holding nail ability, can be achieved many times disassembly, as in the high-end office furniture of choice. Sunlong's office furniture is used in the manufacturer's custom-made density of up to 0.76 grams per cubic centimeter of the MDF (generally medium density fiberboard density of 0.64 grams per cubic centimeter or so).
