Is it OK to use 12 steel gold for a flat foundation?

Is it OK to use 12 plate reinforcement for a slab foundation? I think it's possible, it's going to be a little bit stronger, so we need to do close measurements and calculations so that we can make the building stronger and more practical.

If it's basic, it's okay to use 12 steel bars, because his one is already relatively full, so this is already very good, and the teacher's words can also be used.

This is already very good, because this ingredient is already very sufficient, so this is okay if it is used for a flat base, because its overall effect is already very good.

Slab, we use 12 for its foundation, and its steel bar is also okay, and I think this use can still bring better things to all of us.

If you want to use 12 steel bars for slab foundation, you should first consider the overall strength, and the strength is not enough to cause hidden dangers.

It's perfectly fine to use 12 steel nails for the flat foundation, and it's also a relatively high configuration if you shoot treble.

Flat chicken wings with twelve o'clock Seiko is okay should be sent in batches you can take a closer look at the fart, only the information is special.

Is it okay to use 12 steel bars for the slab foundation, she should be article, you should be okay, you should be okay, slab.

If the steel bar of the slab foundation is still good, you can find it.

This is possible, but the model should be selected according to the specific situation.

If you have a flat foundation, you can use 12 steel bars

Yes, this alloy steel has good strength.

If you convert this into Chinese, you will understand very well zxb column lower plate, kzb span middle plate. Generally, the reinforcement of the plate belt under the column is relatively large, so the design is more economical. Specifically, you can take a look at the 101 atlas.

One. The position of the reinforcement joint should be placed as far as possible in a position that is not stressed or the force is relatively small. General:

1.The bottom reinforcement of the beam is at the bearing, and the upper reinforcement is within the range of 1 3 in the span, and the joint reinforcement shall not exceed 50% (welding) or 25% (lashing lap) in the same section, and the position is staggered for 45d. The vertical reinforcement of walls and columns is staggered with 45d joints at the floor surface of each floor.

The floor slab is stressed by the long steel bar connected to the long bottom reinforcement at the support, the negative steel bar is in the range of 1 3 in the middle of the span, and the other short steel bars are made according to the design length.

2.Reinforcement treatment at the floor construction joints; In case of special circumstances, when construction joints need to be left, the construction insert should be increased at the section, and the number is 30% of the main steel bar area, and the length is taken, and each end extends into the joint. Plate insert adopts 12 steel bars, is placed in the middle of the plate, and the steel bar of beam insertion with 20 is placed in the upper and lower stress steel bar position.

Two. In summary, it is not necessary to lap within the beam, but it can also be done in other positions.

If you are talking about the upper slab on the floor, then the bottom plate reinforcement should be lapped at 1 3 of the net span, that is to say, from the beam side to the 1 3 11g in the atlas, it is very clear that the lap position of the foundation and the floor is just opposite, and the bottom reinforcement of the foundation is lapped in the net span 1 3 in the span.

Most of them are ordinary structural steel, and the common grade is Q235.

First, about the water-stopping steel plate.

Steel plate waterstop, also known as waterstop steel plate. The horizontal components and vertical components of the basement of the building cannot be poured at one time, and the horizontal construction joints are generally left at the position of 300mm on the foundation bottom plate, and the waterproof steel plate is placed at the position of the construction joints. The waterproof steel plate is generally 400mm wide, and half of the new and old concrete are embedded.

Second, the principle of waterproof steel plate:

The position of the joint of the old and new concrete is called the construction joint, which belongs to the weak link of waterproof concrete waterproofing, after increasing the waterproof steel plate, the water penetrates along the gap of the new and old concrete stubble position, and the waterproof steel plate can no longer seep in, and the waterproof steel plate plays the role of cutting off the water infiltration path. Timely infiltration along the gap between the waterproof steel plate and the concrete, the waterproof steel plate has a certain width, and also extends the infiltration path of water, which can also play a waterproof role.

Third, the use of waterproof steel plate:

The main application scope of waterproof steel plate: tunnels, subways, embankments, culverts, construction joints in water conservancy and hydropower projects, basements of high-rise buildings, underground parking lots, etc.

Fourth, the construction points of the waterproof steel plate:

1. Every effort should be made to ensure that the water-stopping steel plate is on the center line of the wall;

2. The welding between the two steel plates should be full to ensure that there is no water seepage, and it is generally double-sided welding. According to the requirements of supervision, it can also be welded on one side;

3. The treatment of the corner of the wall, 1. Bending the whole steel plate; 2. T-shaped welding; 3. 7-figure welding.

4. The support welding of the waterproof steel plate can be welded on the main reinforcement with small steel bars;

5. When the waterproof steel plate passes through the column stirrups, the stirrups can be broken and made into open hoops, which are welded on the steel plate.

Hello, The advantages of using waterproof steel plates are: box foundation or basement, the concrete of the bottom plate and the exterior wall plate are poured separately, and the next time the concrete of the wall plate is poured again, there is a construction joint, when the position of this joint is below the groundwater level, it is easy to produce water seepage. In this way, it is necessary to carry out technical treatment on this seam, and there are many ways to deal with it, among which the more common method is to set up a waterproof steel plate.

That is, when pouring the lower layer of concrete, the 300*3 steel plate is pre-embedded, of which the upper part of 10-15cm is exposed outside, and the steel plate of this part is poured into it together when the concrete is poured next time, so as to prevent the outside pressure water from seeping in. Turn left|Turn right From the advantage point of view, the water-stopping effect of the water-stopping steel plate is lower than that of the water-stopping rubber, because the biggest feature of the water-stopping steel plate is that it is very easy to rust, and the steel plate after rusting will be very troublesome when processing, so if it is necessary to stop water, then try to use water-stopping rubber. Turn left|Turn right The water-stopping steel plate is not a finished product, in fact, there are three steel plates of different sizes to be welded, and when used, it is usually necessary to purchase the processed finished product from a professional manufacturer.

However, in order to ensure the effect of water stopping, it is necessary to strictly control the welding quality and the quality of raw materials. Turn left|Turn right When installing, whether it is a horizontal waterproof steel plate or a vertical waterproof steel plate, it is necessary to make the installation direction of their two warped surfaces face the water surface. Turn left|Turn right to the usual stop.

Q&A: Can the water-stop steel plate be used with a flat plate? You may also be concerned.

Externally attached waterstops.

Water-stop bolts. Water-stopping screw.

Waterstop strip steel plate waterstop.

This kind of water-stopping steel plate can be used with a flat plate, because it can meet your requirements and achieve a purpose of blocking water.

The water-stop steel plate can be used for the flat steel plate, and it is also possible for the installation of the tablet, and the tablet has become the mainstream, replacing the computer, and has become the favorite of many people now.

I think it's better not to use a flat plate for waterproof steel plates, which are easy to break.

A: The fact that the waterproof steel plate should be able to use a flat plate.

The water-stop steel plate can be made of flat plates. In this way, the service can be beautiful.

The water-stop steel plate can be made of flat plates.

Ordinary water-stopping steel plate is commonly used in construction, and others are rarely used, which is made. The large slab that comes out of the slab is generally one meter, 5 or 3 meters by six meters.

The water-stopping steel plate can not be used as a flat plate, and the flat plate cannot stop the water.

In some cases, it can be replaced by concave and convex steps or grooves, but with such a solution, you must be careful when constructing! It must be done in place, otherwise it is easy to leak water.

The suction pump plate can be used on a flat plate, this can be used, I have used it, it is very easy to use.

Factory direct sales of water-stopping steel plate steel plate waterstop belt ** hot-dip galvanized waterproof steel plate.

The water-stopping steel plate can not be used as a flat plate, and the water-stopping steel plate plays the role of cutting off the water penetration path.

Hello, it's available. The watersteel version and the flat plate are about the same.

It stands to reason that it can be used as a flat plate, but it is a bit overkill.

The waterproof steel plate has a height requirement and can be flat.

These can be loaded on a flatbed truck, which is the operating procedure.

This can be used with a tablet, but it looks inconvenient and is not recommended.

On the contrary, the foundation is a long span as the main reinforcement. The floor slab is a short span with the main reinforcement. The top and bottom of the raft foundation should be long span ribs. Floor slabs are the opposite.

Structurally, the foundation is like a plate buckled on the ground to bear the upper load. This kind of foundation greatly reduces the earthwork workload and is more suitable for weak foundations (but must be uniform conditions), especially suitable for residential buildings with good overall stiffness of 5 or 6 floors.

The reinforcement mesh of the plate and the wall must be staggered at the intersection point of the middle part, but it is necessary to ensure that the stressed reinforcement does not displace. The two-way stressed steel mesh pieces must all be firmly rooted.

For the reinforcement of beams and columns, in addition to the design requirements, the stirrups should be set vertically to the stressed ribs. The intersection of plate, secondary beam and main beam, the reinforcement of plate is on top, the reinforcement of secondary beam is centered, and the reinforcement of main beam is below; When there is a ring beam or pad beam, the reinforcement of the main beam is on top.

A flat raft foundation is equivalent to a huge extended independent foundation, with the lower reinforcement in the short direction below and the upper reinforcement in the short direction. It is not an inverted floor like a ribbed slab foundation, which needs to be "laid out in reverse".

Seems to be the opposite, right? The foundation is a long span of the main rib. The floor slab is a short span with the main reinforcement. The top and bottom of the raft foundation should be long span ribs. Floor slabs are the opposite.

Do you know the reinforcement arrangement of beams? And the arrangement of the beams is reversed.

The lower reinforcement is in the lower direction.

The length of the upper reinforcement is in the lower direction.

Raft double-layer two-way reinforcement arrangement: length, short and long, floor double-layer two-way reinforcement arrangement: short length and length.

I don't know what platform the software you are talking about is based on, take a look at RAM, or x86 platform, if it is based on RAM platform, then the vast majority of tablets support it, as long as the hardware keeps up; However, if it is based on the x86 platform, it needs to be supported by a tablet of Windows system.

Tablets with win8 system installed are OK!

1. The flat raft foundation without beams and only columns can be divided into zxb and kzb under the column, and the under-column strip and the mid-span strip are spaced;

2. The flat raft foundation with walls and columns is the flat raft base BPB.
