What is the role of the non-dismantling floor deck in the laying of the project?

The use of the non-dismantling mold floor deck in various fields should be very clear, so what role does it play in building construction? Let's take a look:

The floor deck plate is an anisotropic plate, the effective side length can be calculated through the anisotropy coefficient, according to the ratio of the effective side length, it can be judged whether it belongs to a one-way plate or a two-way plate, if it is a two-way plate, the steel bar in the vertical rib direction is matched in the trough on the crest and along the rib direction, the protective layer should be greater than 20mm, mainly used to maintain the cohesion of the steel bar, the resistance is measured by the thickness of the concrete on the rib in the vertical rib direction, and the thickness of the composite floor deck is measured from the groove along the rib direction, That is to say, the thickness of the composite floor deck is the thickness of the board.

In the laying process of this project, lay the floor bearing plate to connect the steel beam, the end of the floor bearing plate is welded with the steel beam, the middle is welded with the steel beam, the floor bearing plate is connected with a special clamping plier bite pressure hole, the plug is spot welded with the special galvanized plug plate and the floor bearing plate and the steel beam, if the height of the floor structure is inconsistent, the measure of welding steel bar can be adopted, so that the horizontal structure is transitioned step by step, when the elevation is reduced, the I-beam web is welded with angle steel, and when the elevation is raised, the I-beam flange is welded with the channel steel.

Analysis of the elongation performance of the floor deck without demolition

The non-dismantling formwork floor deck itself has good ductility, light self-weight, long natural vibration period, can absorb deformation energy under large deformation, the connection of the structural system is mostly flexible, and the enclosure structure can be displaced with the main structure, so its seismic performance has been greatly improved, reducing its own weight will also enhance its seismic performance, its own weight is reduced by half, which is equivalent to reducing the seismic fortification intensity by one degree, and the seismic action can be reduced by 30%-40% J, thereby reducing many seismic related structural requirements and reducing the project cost. China is faced with a series of problems that affect sustainable development, such as soil erosion and environmental pollution, and the proposal of environmentally friendly buildings came into being, which has the advantages of high energy utilization, good environment, low consumption and long service life on the basis of ensuring people's lives.

Compared with other building structure systems, there is no air pollution and noise, no damage to resources such as forests, and building materials can be recycled, reducing the generation of solid waste, which is conducive to the coordinated development of man and nature, and represents a new level of construction industry.

The above is the editor of the explanation of "what role does the non-dismantling formwork floor deck play in the laying of the project?" Have you all understood the content? I hope the content explained above can help you, thank you for watching, and we'll see you next time.
