Introduction to the difference between beam stairs and slab stairs

The design of various staircases is indispensable in buildings, but no matter what style the staircase is adopted, it is inseparable from two forms, that is, beam staircase and plate staircase. The beam staircase is mainly about the tread board of the staircase section directly resting on the inclined beam, which makes it more convenient for people to walk. And what about slab stairs?

The difference between a beam staircase and a slab staircase

Beam staircase. The beam staircase is to set the inclined beam on the side of the stair inclined plate, the two ends of the inclined beam are supported on the beam, and the beam is supported on the staircase wall or column, which constitutes the beam staircase. Of course, the advantage of the beam staircase is that it will save materials when the staircase section is longer.

Of course, there are also disadvantages, that is, the formwork is more troublesome during construction, and the appearance of the slab staircase is not good-looking. At this time, the construction unit will have to see which one is more suitable for itself. There is no blind choice.

Beam stair force transmission route: tread plate - diagonal beam - platform beam - wall or column. When the tread plate is cracked, if the stair beam is intact, it is only a local problem.

Reinforcement method: transverse reinforcement of the flight section, resting on the inclined beam, plus distributed reinforcement. The main reinforcements of the platform are arranged in short spans, arranged in the direction of long spans, and distributed steel bars are placed vertically.

Secondly, the slab staircase. The slab staircase is composed of three parts: the staircase, the beam body and the platform, the floor slab is an inclined plate, and the two ends of the slab are supported on the platform beam, so the staircase is called the slab staircase. Of course, the advantage of the plate staircase is that the surface looks relatively flat and smooth, and the support formwork is more convenient during construction, which brings a lot of benefits to the construction.

However, there are also disadvantages, the inclined plate is thicker, and when the span is larger, the material will be used more. So that's what everyone has to consider when choosing.

Force transmission route of slab staircase: stair slab - platform beam - wall or column. It is more economical when the plate length is less than 3 meters. The plate can't crack! So add temperature reinforcement.

Reinforcement mode: longitudinally arranged with stressed steel bars, and the steel bars rest on the platform girder and floor beam. The structure requires distributed reinforcement.

A slab stair consists of a run plate, a landing plank, and a platform beam. The flight plate is an oblique toothed plate, which is supported on the platform beam and the floor beam, and the lower section of the bottom layer is generally supported on the ground ridge beam.

For many users, the design of the staircase may look exactly the same, and there is not much difference, but in fact, in the internal structure of the staircase, the difference is still very large. The above explains the difference between beam stairs and plate stairs, plate stairs have many advantages, simple stress, and construction is also more convenient, and many family users are more suitable for plate stairs. That's the end of the introduction, I hope the article can help everyone.

The difference between a beam staircase and a slab staircase

There are different types of stairs, there are beam stairs and plate stairs when designed, and different stairs, its structural characteristics are also different, today I will introduce to you what are the differences between the two types of stairs?

1. The difference between the brother hail amuses the beam staircase and the plate staircase.

1. The installation position is different, the Liang's staircase is set on the side of the inclined plate of the staircase, and the two ends of its inclined beam will be supported on the beam, and the beam is supported on the wall or column, so the Liang's staircase is formed. The slab staircase is a kind of inclined slab, which is supported on the flat beam platform, and is mainly composed of three parts, which is called the slab staircase.

2. The force transmission route is different, the beam staircase passes through the stair plate, and then passes through the inclined beam and the flat beam platform and finally conducts to the wall or column, while the force transmission route of the plate staircase is through the leakage staircase plate and the flat beam platform, and finally reaches the wall or column, which can be compared, the two are completely opposite.

3. The reinforcement method is also different, the reinforcement of the former will be arranged according to the long span direction and vertically distributed on the steel bar, but the stair reinforcement method of the latter will be shelved on the flat beam platform.

2. What small problems need to be paid attention to in staircase design?

1. The staircase must be strong and very safe, and it should be noted that its noise is very small, mainly because of its tread material, as well as the connection of various parts, which is very important, and special attention should be paid to when choosing.

2. There are many staircase materials now, including solid wood and PVC, in short, we must choose environmentally friendly materials, otherwise some environmentally friendly products will emit harmful substances, which will have a certain impact on the human body.

3. When designing the staircase, we must pay attention to all the parts to be smooth and flat, and there can be no sharp objects, otherwise it will cause some damage to the family.

4. The tread width of the staircase should meet certain requirements, and it should not be less than 22 cm.

5. The spacing of the railing of the staircase should also be within a certain range, taking into account the safety of children, it should be less than 12 cm to prevent children from passing through and the danger of falling.

Summary: There are many details that need to be paid attention to when designing stairs, and different stairs also have different property characteristics, such as beam stairs, slab stairs and so on.

1. The installation position is different: the Liang's staircase is set on the side of the inclined plate of the staircase, and the two ends of its inclined beam will be supported on the beam, and the beam is supported on the wall or column, so the Liang's staircase is formed. Banshi refers to the pure staircase is a kind of inclined slab, which is supported on the flat beam platform, mainly composed of three parts, this is called a slab staircase.

2. The force transmission route is different: the beam staircase passes through the stair plate, and then passes through the inclined beam and the flat beam platform and finally conducts to the wall or column, while the force transmission route of the plate staircase passes through the stair plate and the flat beam platform, and finally reaches the wall or column, which can be compared, and the two are completely opposite.

3. The reinforcement method is also different, the reinforcement of the former will be arranged according to the long span direction and vertically distributed on the steel bar, but the stair reinforcement method of the latter will be shelved on the flat beam platform.

The above is that I have introduced to you the difference between beam stairs and plate stairs, I believe you have a certain understanding of this, I hope to help you.
