Concrete floor slab safety issues, is it safe to hit concrete on the floor slab

Hello, I come to your question, so that the construction is definitely not good, does not meet the design specifications, there will be potential safety hazards:

1. First of all, the floor steel bar into the wall is too shallow, the anchorage depth is not enough, the normal anchorage depth is 10d 20d, generally in modern buildings often take the median value of 15d, that is, 15 10mm = 150mm, that is to say, under normal circumstances, the floor reinforcement should be implanted in the original wall 150mm, at least not less than 100mm, and your floor steel bar is only 50mm, which is very uncompliant;

2. Secondly, I don't know how your floor steel bar is connected with the original wall, and it is normal to use the "reinforcement" method to connect with the original wall.

The spacing of chemical anchors is 400mm, and the chemical anchors can also be changed to the reinforcement method, and the connection parts of the angle steel and the floor and the wall should be reinforced with adhesive steel glue, and it is best to use professional construction personnel to ensure quality and safety.

You still have no problem with the thickness of your slabs and the reinforcement. In this way, you can use it with confidence after the reinforcement treatment, if you have any questions, please continue to ask.

Nowadays, whether it is a high-rise building or a duplex building, cast-in-place floor slabs are not opened, and the safety of stairs leading to the upper floors is very important. Therefore, our construction personnel must put safety in the first place when casting the floor slab, so as to ensure the solidity of the floor. Next, Wuhan cast-in-place floor slab company Xu Risheng will tell you how to ensure the safety of cast-in-place floor slabs.

First of all, for the existing floor slab and other construction projects, we all require that quality is important, is the first, and improving the quality of cast-in-place construction is also a consideration for personnel safety. We must prevent the problems that often occur in the construction, communicate with the technical personnel in advance to minimize the unfavorable factors, and at the same time prevent the problems before they occur. For particularly important construction projects, the requirements for technicians are strict.

Secondly, for the construction unit to explain the general requirements of the construction, each construction personnel must resolutely implement the construction standards, and the workers in each position must strictly control the quality. At the same time, there are certain requirements for the quality of construction personnel, and everyone must pay attention to quality and safety.

The third step, the acceptance of the cast-in-place floor slab, the ground must comply with the construction project quality acceptance regulations, that is, the surface of the floor slab can not peel, can not sand, but also to keep clean and can not have defects. In the process of cast-in-place floor slabs, it is necessary to work carefully and meticulously to avoid problems in the future, and it is necessary to successfully avoid future troubles. After the construction is completed, the floor slab needs to be protected to prevent other construction from damaging the cast-in-place floor slab.

My house is also made of mixed earth floor slabs, but I feel that the steel bars you insert into the wall are a little shorter, what is the density of your steel bars, whether the floor slabs are used for storage or living people, how much force to bear, my family's steel bars are made into a net, and now it has been built for 10 years.

You can find a special unit for geotechnical structure design to identify it.

Summary. Dear, safe.

Dear, safe.

Concrete can be made on top of the floor slab, so that rain leakage will be prevented. Concrete, abbreviated as concrete (tóng): refers to the general term for engineering composite materials that are cemented into a whole by cementitious materials.

The word concrete often talked about by the beam seepage brigade refers to the use of cement as cement, sand and stone as aggregates; Cement concrete, also known as ordinary concrete, is widely used in civil engineering engineering by mixing with water (can contain admixtures and admixtures) in a certain proportion and is mixed by rubber benches.

Characteristics: Concrete has the characteristics of abundant raw materials, low quality and simple production process, so that the amount of slag silver buried is getting larger and larger. At the same time, concrete also has the characteristics of high compressive strength, good durability, and wide range of strength. These characteristics make it widely used, not only in various civil engineering projects, but also in shipbuilding, machinery industry, marine development, geothermal engineering, etc., concrete is also an important material.

It's safe, but you have to make holes in the wall or plant reinforcement in the beam.

No problem! 10 cm thick concrete! Only 235 kilograms per square meter! No damage to the floor!

If you are satisfied with the conversation, you can give a thumbs up.

The cement is matched with C20 concrete, and the water-cement ratio is appropriate with 250kg per cubic meter. As long as the concrete vibrates and compacts, and the supporting node reinforcement is reliable, the problem is not big.

There is nothing wrong with the floor, but the maintenance should be doubled with extra care to prevent micro-cracks and leaks, and if it is a column, it is a bit of a trouble.

250 per square is equivalent to about 200. Grade.

c20 or so. No problem on the third floor. The general beams in the countryside are C20. I make commercial concrete, so it should be no problem.

Can concrete still live on its own? It seems that it has long been allowed, isn't there a concrete company? It is necessary to use concrete from a concrete company, door-to-door service, delivery to the construction site.

Brother... Current Engineering·· If it is not a national-level project, but only a private house, the on-site construction requires concrete... Very casual, I believe you feel the same way, it's the current steel bar·· The requirements are very strict, and when the structure is settled... Several times the coefficient was multiplied all the way·· Rebar is often very safe... The cement of the concrete is less 1 4, I believe that the strength of the concrete is definitely unattainable·· According to the theoretical analysis··· It's very reinforcing steel that doesn't match... It can lead to brittle rupture. However, in the actual construction, as long as the owner and the supervisor are mixed... It's all right... There are a few built houses that will collapse...

As for the responsibility to society... It's up to you to look at your personal awareness. Guaranteed, this house will never collapse, if there is no problem with the steel bar... There will be no security issues in a short period of time.
