Which pillars on the ground floor of a general high rise building can be beaten and which cannot be

The development of modern society is very rapid, especially in the past few years, we can clearly feel that the development of the cities around us is getting better and better, and the most obvious change is the establishment of high-rise buildings in the city, which used to be only a first- and second-tier city.

Yes, it's very common now. Sometimes we think about how such a tall building is built, sometimes we are in the underground parking garage, we will find a lot of columns, these columns are very large, seriously affect the aesthetics, but for some of our design, we sometimes want to reduce some unnecessary columns, but this will be dangerous.

Anyone who has studied architecture knows how compressive our concrete is.

It's still very powerful, but when we design the building, we will specifically calculate the bearing capacity, and the bearing capacity of each floor is strictly required, and if there is no such requirement, there will be serious consequences. Sometimes what we are most worried about is not the compressive capacity of the ground floor pillars of our high-rise buildings, but the fear of earthquake resistance, fire prevention and other problems, because of the occurrence, on the contrary, earthquake, fire prevention and other problems will destroy the spatial structure of the building, as well as the three-dimensional structure, which will lead to the collapse of the building in serious cases, for example: we find that the pressure resistance of the opened bottle is much worse than that of the unopened bottle, which is the same as the bottom pillar of our building.

If we really want to hit our bottom pillars,First of all, we have to observe the drawings, we can't hit our main column, that is, the load-bearing pillars and beams of our building, and we must wait for all the structures and loads it bears to be dismantled before they can be removed, so as to ensure that both sides of the building produce a tensile stress and a compressive stress on the ground. The columns that can be played are some auxiliary columns, and the load-bearing of such columns is relatively small, mainly playing a fixed role, and the demolition will not have much impact on the building.

Of course, we still don't want to hit the pillars on the bottom floor of the floor, because when we build the floor, our drawings are completed after strict calculations and all aspects of consideration, and try to meet the principles of economy, environmental protection and safety. The three-dimensional structure of the building cannot be changed at will.

Generally, the load-bearing pillars and beams of the pillars on the ground floor of high-rise buildings cannot be beaten, and these columns carry the weight of the whole house and are the backbone of the whole building. In addition to these important load-bearing columns, some other auxiliary columns can be hit. If you need to hit the ground floor pillars of a high-rise building, you must consult a professional building engineer or a person related to the house builder before acting.

The columns of the general building are divided into load-bearing columns and non-load-bearing columns, the load-bearing columns must not be smashed, and the non-load-bearing columns can be smashed.

If the house is framed, these pillars are basically load-bearing columns and cannot be knocked off; If the house is not framed, it depends on whether the pillars are on the load-bearing wall, and if they are, they cannot be knocked down, and if they are not, they can be knocked down.

Your house is obviously a brick house, and the two black pillars in the circle are immovable, really brother.

But if you decorate, it looks like the living room is very awkward, block the door of the north room, so that the living room has a complete wall, and it will feel better to put a TV.

The section of the wall between the room on the north side and the dining room has a door, and that's where you draw the red circle.

If you're afraid that it will smell from the kitchen, try to move the door to the side of the column.

The wall between the living room and the balcony can't be knocked down either, hehe, don't think about it.

The black solid ones should be load-bearing guns or pillars, and the concrete walls and pillars don't touch the others anyway.

Anyone who is involved in construction should know that concrete has a strong ability to resist compression.

How the load is transferred.

The load on the plate is transmitted to the beam, and the load on the beam is transmitted to the column, and the load is transmitted down along the column, so the beam and plate at the bottom only bear the load of one layer and will not be crushed, and the column is larger and larger the further down.

The selection of the cross-sectional dimensions of the columns is determined by the vertical load, and the dozens of floors you see are heavy, but the bearing capacity of the columns is higher.

The parameters of the bearing capacity calculation formula are related to the concrete strength, the strength of the reinforcement and the corresponding area, as well as the adjustment coefficient of the seismic bearing capacity, the coefficient related to the seismic grade of the building, and finally the requirements of the axial compression ratio limit, which meet the requirements of the column will never break.

1m concrete column compressive capacity, overall stability according to consideration, compressive capacity:

Under the comprehensive consideration of various factors such as wind load, force and crowd load, a tensile stress and a compressive stress are generated on the ground on both sides of the high-rise building.

Moreover, the concrete used in the construction of high-rise buildings is very strong, and the final guarantee is that the structure can meet the design requirements under the action of horizontal load.

Therefore, with good structural design and excellent construction, the columns will not be crushed. Moreover, the consequences of dozens of floors are particularly serious once there is a problem, so the design and construction will be more rigorous.

Why aren't the load-bearing columns of a 100-story building fracked? After reading it, I sighed that the workers were too wise.

A frame structure is a structure that consists of many beams and columns to bear the full load of the house. In high-rise civil buildings and multi-storey industrial plants, the load-bearing brick wall can no longer meet the requirements of large loads, and the frame is often used as the load-bearing structure. The load of the house includes the weight of people, furniture, articles, machinery and equipment, as well as the weight of floors, walls and itself.

The wall built within the frame only plays the role of enclosure and separation, and does not bear other loads except for the weight of the burden itself. In order to reduce the load on the frame, lightweight walls should be used as much as possible, such as foam concrete blocks (wall panels) or hollow bricks. In order to speed up the progress of the project, save the formwork and the jacking brace, the construction method of partial prefabrication (such as columns) partial cast-in-situ (beams), or cast-in-situ joints of columns and beams can also be adopted. [1]

The correct answer is: for building frame structures, when the length of the masonry infill wall is more than 5 meters, it must be made as structural columns.

You are **, you can go to the decoration company and ask, he will explain it clearly.

Solid black lines cannot be knocked off, blank lines can be removed.

After the township test, Chu Sheng told Dong Sheng the truth: he fell off a cliff and died in order to collect medicine for Dong Sheng, but in order to repay his kindness, his soul has always accompanied Dong Sheng and possessed him to take the exam on his behalf.

High-rise buildings have been beaten with pillars and stone concrete, and if they were treated at that time, the quality of the building would not be affected by the new concrete. If you don't deal with it at the time and deal with it afterwards, it will have an impact.

Definitely not, the first thing to do is to lay a solid foundation, otherwise no matter how good it is, it will be a dangerous house.

As long as the concrete is compact, the chisel can be removed, and the quality is generally not affected.

Of course, it will affect, and everything must be implemented according to the standard.

If the steel bar is not deformed after the inspection, the concrete number is also up to standard, and the rising part can be chiseled, which will generally not affect the quality.

The building is good for foundation piling.

The direct foundation slab is stressed, that is, the independent foundation, which directly transmits the upper load to the foundation. The upper part of the pile foundation is called the cushion cap, which plays the role of transmitting force. 100% of the pile cap has piles, and it can be a cap under the shear wall, or a cap shared by several columns (the piles of the cap can be 1 to many), it can be a small cap, and there is also a large cap; Independent Foundation Points:

There are separate foundations with and without orders, and there are generally foundation beams connecting them. Among them, the pile cap, which is also regarded as an independent foundation, a strip foundation, and a belt foundation, is generally found in brick and concrete, bearing the wall above; The independent foundation is independent, one by one, and the dimensions are marked; The amount of calculation is to calculate the volume of concrete, and the template calculates the contact area with concrete. Independent Basis:

When the upper part of the building is a frame structure or a single column, an independent foundation is often used; If the column is prefabricated, it is in the form of a cup-shaped foundation.

Pile foundation: When building relatively large industrial and civil buildings, if the soft soil layer of the foundation is thick, the shallow buried foundation can not meet the foundation strength and deformation requirements, and the pile foundation is often used. The function of the pile foundation is to transfer the load through the pile to the deep buried hard soil layer, or to the foundation through the friction around the pile.

According to the construction method, it can be divided into reinforced concrete prefabricated piles and cast-in-place piles. Reinforced concrete precast piles: This kind of piles are prefabricated at the construction site or component yard, driven into the soil with a pile driver, and then poured on the top of the pile reinforced concrete cap.

It has a large bearing capacity, is not affected by changes in the groundwater level, and has good durability. However, due to its weight, transportation and hoisting are more difficult. The vibration is large when the pile is driven, which has a certain impact on the surrounding houses.

Reinforced concrete cast-in-place piles: casing bored piles, bored piles, and blasted and expanded cast-in-place piles.

If you want to read the geological report, it is best not to drive piles and save a lot of money.
