Can a beam that rises above the floor of a house possibly called a counter beam be smashed?

No, the role of the anti-beam is not only to support the balance structure to maintain stability, but also to play the starting point of the bar connection.

The anti-beam is only a need, and for some reason (such as insufficient floor height, etc.) to make the beam to the upper part of the floor slab (the general beam is flat with the floor slab). However, the foundation beam at the foundation is generally an anti-beam.

The anti-beam is often due to some reasons (such as: the floor height is not enough, the bottom surface of the beam needs to be flat, and the upper part of the beam can be turned up, etc.), and a part of the beam height is made above the floor slab, or the surface of the raft foundation needs to be flat and the beam is made below the slab. Generally, the concrete beam cast-in-place with the slab is designed according to the "T-shaped beam" in the span, and the "rectangular beam" is designed in the middle of the anti-beam span.

The general structural beam is not exposed to the outside half a meter high, the exposed beam should be the decorative beam of the entire floor, if it is decorative, of course, there is no problem because it will not affect the structure of the floor, if it is a load-bearing and structural beam, it can not move, if it touches the **, it will form a catastrophic collapse.

It should be the window sill from the house to the terrace (about half a meter above the ground), which may be called a reverse beam. Some people smashed it and changed it into a door. How does it affect the building? Will it become a dangerous building? What is the function of this beam? I would like to know too. Thank you.

Do they really dare to do it, and no one cares when they smash it? That is an important structure of the house, commonly known as ring beams. Smashing it is like sawing off the girder of a bicycle.

Half a meter higher may be a structural ring beam, it is not recommended that you smash it.

Summary. Hello dear. The anti-beam is only a need, for some reason (such as insufficient floor height, etc.) and the beam is made to the upper part of the floor slab (the general beam is flat with the floor slab) in the foundation foundation vice versa.

Hello dear. The head of Zheng Tong is just a need, for some reasons (such as insufficient floor height, etc.) and the beam to the upper part of the floor slab (the general beam is flat with the floor number of plates) in the foundation on the contrary.

The top floor of the building is more with anti-beams, that is, the beam is above the roof, and the roof is sheltered below the beam.

The anti-beam is often due to some reasons (such as: the floor height is not enough, the bottom surface of the beam needs to be flat, and the upper part of the beam can be turned up, etc.), and a part of the beam height is made above the floor slab, or the surface of the raft foundation needs to be flat and the beam is made below the slab.

Generally, the concrete beam that is cast in situ together with the slab is designed according to the "T-shaped group banquet beam" in the middle of the span, and the reverse beam needs to be designed according to the "rectangular beam" in the span. The "anti-sorghum" of the reinforced concrete structure has two completely different connotations.

First, from the direction of nuclear elimination of external forces, the concrete floor and roof slab system are divided from the structure, and the gravity load is vertically downward, which is the ordinary sorghum; If the roof system is hypothetically turned upside down and placed on the foundation, it becomes that the reaction force of the foundation is applied to the raft, and the plate then transmits the earth pressure to the sorghum. This system is the opposite of the floor and roof system; At this level, it is understood that the sorghum of the floor and roof sorghum slab system is ordinary sorghum; The sorghum of the raft foundation system is anti-sorghum.

secondly, the virtual chong cluster is divided from a structural point of view, with ordinary sorghum, slab on top and sorghum on bottom; Sometimes, in order to increase the headroom of the lower space, the beam is placed on top of the slab, which is also called anti-beam. For raft-shaped foundations, the slabs are at the bottom and the sorghum is at the top, which is ordinary; The sorghum is at the bottom, the plate is on the top, which is the anti-beam, and the beam is also the reverse beam when it is flush with the plate. Under normal circumstances, the load is transmitted from the plate to the secondary beam or directly to the main beam, the secondary beam is transmitted to the main beam, and the main beam is then transmitted to the column, the concrete floor and the roof slab system are this difference, and the foundation is also like this, the load-bearing beam is the ordinary beam, and the reverse beam is the reverse beam. Judgment.
