How much can an ordinary floor with a load of 1 square meter bear?
General household ordinary floor load-bearing 150KN, that is, equivalent to 150kg per square meter. The thickness of the general household floor is in 10cm. General floor he is the horizontal support and connection component of walls and columns. Therefore, the stability of the wall column must be maintained, and the floor can also play the role of heat preservation and thermal insulation. And now the use of floors in home decoration is also more.

Profiled steel plate has the advantages of light unit weight, high strength, good seismic performance, rapid construction, beautiful appearance and so on. It is a good building material and component, mainly used in enclosure structures, floors, and can also be used in other structures. According to different functional requirements, profiled steel plate can be pressed into waveform, hyperbolic waveform, rib shape, V shape, stiffening type and so on.
Extended data:
Deficiency of carbon steel:
(1) low hardenability. In general, the maximum quenching diameter of carbon steel is only 10mm-20mm.
(2) the strength and yield strength are relatively low. For example, the σ s of ordinary carbon steel Q235 steel is 235MPa, while that of low alloy structural steel 16Mn is above 360MPa. The σ s / σ b of 40 steel is only 0.43, which is much lower than that of alloy steel.
(3) the tempering stability is poor. Because of poor tempering stability, carbon steel needs to use lower tempering temperature in order to ensure higher strength, so the toughness of carbon steel is low; in order to ensure better toughness, the strength is low when tempering temperature is high, so the comprehensive mechanical properties of carbon steel are not high.
(4) it can not meet the requirements of special performance. Carbon steel is often poor in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic properties, which can not meet the needs of special performance.

What is the theoretical weight of 1. 0 thick profiled steel plate YX50-125750?
YX-35-125750 theoretical weight is 7.85KG per square meter theoretical weight is 7.85/0.75=10.467kg. The thickness of this model is 0. 2-1MM.
The pressed steel plate that supports the floor concrete is called profiled steel plate. In the name of overseas, the meaning of profiled steel plate is more extensive, including the colored steel plate formed by roof and wall is called profiled steel plate, and the profiled steel plate supporting floor concrete is called steel bearing plate or building bearing plate. That is, the profiled steel plate referred to in the mainland is equivalent to steel bearing plate or building bearing plate.
When profiled steel plate is used as roof panel and wallboard of industrial factory building, the amount of steel per square meter is about 511 kg without thermal insulation requirements. When there are thermal insulation requirements, mineral wool board, glass wool, foam and other thermal insulation materials can be used. The composite floor made of profiled steel plate and concrete can save the wood formwork and can be used as a load-bearing structure. At the same time, in order to strengthen the bonding force between profiled steel plate and concrete, it is appropriate to pre-weld studs or press two-way stiffeners on the steel plate.

How to choose the bearing plate? What specifications do you have?
Selection of bearing slab
The thickness of bearing plate mainly depends on the thickness of floor (concrete) and the distance between secondary beams. This calculation has technical content, and it is calculated according to the relevant data such as section modulus, section moment of inertia and so on. Here, let’s briefly talk about the usual basis of judgment:
Under normal circumstances, the span between steel beams is less than 2m and the thickness of bearing plate is 0.75m-0.8mm; the thickness of bearing plate of 2-2.5m is 0.8-1.0m; the thickness of bearing plate of span of 3-4m is 1.5mm, and the span of more than 5m is finally supported by temporary support.
Of course, the above is only considered from the point of view of plate thickness, not fully taking into account the plate shape, strength and other factors. Another factor that is easy to overlook is that the quality of the screw also determines the thickness of the bearing plate. The better the screw, the stronger the bearing capacity of the bearing plate.
The selection of stud length needs to consider the following two aspects:
1. The post-weld stud height is greater than the wave height of profiled steel plate 30MM (pay attention to select the type of floor)
2. The concrete cover on the top surface of the stud is not less than 15MM (pay attention to the total thickness of the floor) the diameter should not be greater than 19MM.
The types of bearing plate studs are “8”, “10”, “13”, “16”, “19”, “22” and “25”. Studs are usually used in steel structures and are commonly used in column feet and floors. Generally speaking, the column feet with high stiffness are extended into the concrete by the steel column, and the steel column embedded in the concrete is surrounded by studs.
Extended data
The construction process of the building bearing plate is generally as follows: elastic line → cleaning board → hoisting → cloth board → cutting → pressing → side welding → end welding → hole sealing → acceptance → stud → reinforcement → embedded parts → pouring → maintenance. Of course, so many processes are inseparable from a good labor organization, the following process can also be dealt with separately according to the actual situation on the spot. Labor organizations should be divided into two groups:
The first group is responsible for transporting materials, including cleaning and reverse transportation, until the bearing plate is accurately hoisted to the construction site in accordance with the construction schedule, including 5 lifting workers.
The second group is responsible for laying, including reinforcement, cutting, installation and hole retention. Every three people are divided into a group, responsible for one session, and four teams work at the same level at the same time. When binding steel bars and pouring concrete in the next process, special personnel should be left to strengthen the maintenance of the laid bearing slabs. The specific methods are as follows:
The main results are as follows: (1) the center line of the steel beam is popped out in the paving area, and the center line of the main beam is the control line of the fixed position of the floor bearing plate. The lap width of the lap steel beam of the bearing plate is controlled by the centerline of the main beam, and the position of the solder joint of the penetration welding between the bearing plate and the steel beam is determined. The centerline of the secondary beam will determine the welding position of the penetration stud.
Because it is difficult to observe the specific position of the secondary beam flange after the floor bearing plate is laid, the centerline and flange width of the secondary beam are bounced back on the centerline of the main beam, and when fixing the stud, the centerline and flange width of the secondary beam should be bounced back to the bearing plate on the surface of the secondary beam.
(2) in the stacking site, the bearing plate shall be cleaned out according to the bill of materials, and marked with a clear layer, area and number, marked with a marker, and accurately transported to the designated part of the construction.
(3) the special soft sling is used during hoisting to ensure that the bearing plate is not deformed as a whole and not crimped locally. The multi-story steel structure design generally adopts the three-story one-column installation technology. (needless to say about the single-story one) when installing the bearing plate, it should be constructed synchronously with the steel structure column beam, and there should be a difference of at least 3 layers. Therefore, when the bearing plate is hoisted, it can only be sheathed from the upper beam and column, and the lifting industry should be controlled by layers between the beam and column.
(4) using plasma cutting machine or cutting forceps to cut edges and corners, the margin should be controlled within the range of 5mm when cutting and laying out, and measures should be taken to prevent slurry leakage when pouring concrete.
(5) the bite clamp is used to press the connection between the bearing plate and the side plate of the bearing plate, so that the whole plate is connected between the single bearing plate. First spot welding the side of the bearing plate, then fixing both ends, and finally using studs to fix.
(6) strengthen the maintenance of concrete.
