What is a Reinforcement Truss Floor Deck Advantages of Reinforcement Truss Floor Deck

The steel bar truss floor deck is a combination template that processes the steel bar in the floor slab in the factory and welds the steel bar truss and the galvanized profiled steel plate into one. Concrete is poured in its Shangmin to form a reinforced truss concrete floor slab.

In addition to the advantages of the first two generations of steel floor bearing plate and cast-in-place concrete slab, it also has the advantages of leading technology, fast construction, seismic resistance, fire prevention, good anti-corrosion performance, stable quality, safety and reliability, smooth bottom plate, economical material selection, low comprehensive cost and rich plate type.

The floor deck is a floor slab that is poured with profiled steel plates instead of a permanent bottom form, and steel bars need to be placed.

The steel bar truss plate is made of the floor steel bar into a truss, welded on the profiled steel plate, and the steel bar truss is facing upwards and poured in the floor slab. There is no need to put additional reinforcement. There is no need to consider the force on the profiled steel plate.

The main difference between the steel truss plate and the floor bearing plate is that the stressed structure of the tensile part is different, one is the truss stressed structure welded by steel bars, and the other is the stressed structure of the steel bearing plate. Compared with the former, the cost of the two is lower, but the production is more cumbersome; The latter is more costly, but easy to construct.

1.The amount of steel bar bundling on site, about 5kg of steel truss, ordinary floor bearing plate.

Around 12kg.

2.Temporary support, steel truss plate without support plate span can be set to meters, ordinary floor bearing plate is also 3 meters, need a large number of temporary support.

3.Man-hours, steel truss slab greatly saves on-site labor and man-hours, and management costs.

and labor costs are greatly reduced.

4.The construction period is advanced and the economic benefits are won in advance.

5.There is no need for shear resistance and fire prevention reports, and the performance of the steel truss plate is basically the same as that of the traditional cast-in-place plate, and there is no maintenance cost in the later stage.

The above is the 5 differences between the truss floor deck and the general floor deck summarized by Jingboxing, I hope it will help you.

Steel truss floor deck was born around 2007, but also want to replace the floor deck or compete for the floor deck market, the effect is similar to the floor deck, but also for floor use. The difference is that the steel truss floor deck can be used in concrete projects, while the floor deck is not used much in concrete projects. The steel bar truss plate is welded with two steel bars and galvanized plates, wherein the galvanized plates are made of galvanized plates, which are similar to flat plates; The steel truss is made of a lot of steel bars by welding, which mainly plays the role of supporting the force.

Dear, hello, I am happy to serve you, the answer is as follows The area of the steel truss floor deck is greater than 3 meters, and the truss floor deck is more than 3 meters span to be supportedThe amount of steel bars on site is about 5kg, and the ordinary floor deck is about 12kg.

2.Temporary support, the steel truss plate is larger, and the span without support plate can be set to meters, and the ordinary floor bearing plate is larger than 3 meters, which requires a large number of temporary supports. 3.

Man-hours, steel truss plate greatly saves on-site labor and man-hours, and management costs and labor costs are greatly reduced. 4.The construction period is advanced, and the economic benefits are won in advance5

There is no need for shear resistance and fire report, and the performance of the steel truss plate is basically the same as that of the cast-in-place plate, and there is no maintenance cost in the later stage.

1.Economy. The stress mode of the steel truss is reasonable, the material selection is economical, and the cost awareness of comprehensive dust and Wuhe is obvious; Truss height and rebar diameter can be adjusted to use floor slabs with larger spans; Can be designed as a bi-directional board.

2.Convenient. The on-site reinforcement binding workload can be reduced by 60% or 70%, which can further shorten the construction period; The truss hand mode provides greater stiffness of the floor deck, which can greatly reduce or eliminate the need for temporary support rolling thickets.

3.Safe. The mechanical properties are basically the same as those of the traditional cast-in-place floor slab, and the floor slab has good crack resistance; The fire resistance performance is comparable to that of traditional cast-in-place floor slabs, and is better than that of profiled steel plate composite floor slabs; The bottom mold does not participate in the force in the use stage, and there is no need to consider the problem of fire resistance and anti-corrosion.

4.Reliable. The steel bars are arranged evenly, and the spacing between the upper and lower steel bars and the thickness of the steel bar protective layer are reliably guaranteed; The double-discounted edge lap design effectively guarantees the implementation quality of the composite floor slab; The two-way stiffness of the floor slab is similar, which is conducive to the seismic resistance of the building; The quality of bolt welding or splicing is easier to guarantee.

1.Larger span capability:Reinforced truss floor decks can achieve large spans and can be used to construct buildings with larger spaces, such as industrial plants, gymnasiums, stations, etc.

It can effectively support and carry loads over large spans, providing a more flexible and open space layout.

2.Lightweight and high-strength:Steel truss floor decks are made of steel as the main structural material, which has a low dead weight and has good strength and stiffness.

Compared with the traditional concrete floor slab, the reinforced truss floor deck can reduce the dead weight of the floor slab, and reduce the requirements of the building structure for the foundation and foundation foundation.

3.Fast construction and flexibility:Reinforcement truss floor decks can be prefabricated in the factory and then transported to the site for installation in one go, reducing construction clearance time and labor costs.

Prefabricated decks can be customized to meet the needs of the project, providing greater flexibility and choice.

4.Easy installation of equipment and service facilities:Due to the open substructure of the front floor deck of the rebar truss, it is easy to install pipes, wires, and other equipment, and provides more flexible layout and adjustment options.

5.Sustainable & Eco-Friendly:The main material of the steel truss floor bearing plate can be retraced and infiltrated, which reduces the waste of resources.

In addition, the production and processing of steel produces relatively few pollutants, making steel truss floor decks an environmentally friendly and sustainable building solution.

It is important to note that when using steel truss floor decks, it is important to ensure that the design and installation comply with the relevant codes and standards, and that proper quality control and supervision are carried out to ensure the safety and reliability of the structure.

In recent years, steel truss floor decks have slowly entered the construction industry, and have been paid attention to and widely used. More and more large-scale projects and image projects have adopted steel truss Xiangchai floor bearing plates. Famous examples include the Bird's Nest Olympic Stadium, the Jin Mao Tower in Shanghai, the Guangzhou World Convention and Exhibition Center, and the Water Cube.

A lot of data proves that the steel truss stupid ruler floor deck has gradually changed the situation of concrete planning and masonry planning in the domestic construction industry, today with Shengwei steel structure to learn how to plan and select the steel truss floor deck: The first is the planning plan (conceptual planning), which is the key to the planning of the steel truss floor deck, and what kind of planning and planning has a great impact on the interests of the project. The second is component planning, what kind of component planning is used, and the distribution of the force of each bearing point must be calculated.

The third is the cross-sectional shape, which not only allows the planning piece to accept the component to the maximum, but also requires the shape of the cross-section to have an artistic sense in the human investigation. The fourth is the miniaturization of the node structure, which allows the planning parts to be mainly affordable in cost, and occupies space that is not too large.

The construction process of steel truss floor bearing plate is: steel bar truss floor bearing plate is an unsupported compressed composite floor bearing plate processed and made in the background of the factory, which is directly supported on the steel beam or concrete beam.

It is not only the stressed steel bar of the concrete floor slab, but also the supporting scaffold, and the template of the concrete floor slab, which combines the functions of the skeleton and the template bearing the load into one, saves the time of erecting the scaffold printing and supporting the formwork, and reduces the amount of steel bar binding on the site by 60% and 70% at the same time.

The application and construction of steel bar analysis frame floor bearing plate in the project is simple and convenient, and at the same time, mechanized production can be realized, which reduces the input of manpower and turnover tools.

The process principle of steel truss floor bearing plate

The steel bar truss floor deck is a non-supported pressed composite floor deck plate, which is processed and made in the form of shaping processing in the processing plant, and is installed at the construction site after being transported to the construction site, and the steel bar truss floor deck is directly supported on the floor concrete beam or steel beam during installation, and then the pipeline is laid and the steel bar is tied according to the design requirements, and finally the concrete is poured.

The self-weight of the concrete floor slab after forming produces negative bending moment and positive bending moment in the use stage, which is completely borne by the steel bar, and will not produce tensile stress inside the concrete, and the tensile stress of the concrete itself is significantly reduced, and the crack width is reduced, and the existence of galvanized steel plate also avoids the exposure of cracks under the floor slab, improves the service performance of the floor slab, and improves the durability.
