Is the crack in the floor slab of the commercial house a crack that affects the safety of the house,

Cracks in the floor slab of the house will affect the safety of the house, but it will not collapse suddenly, if it encounters bad natural weather, such as **, it may not be able to withstand it, and it is this kind of house that is most likely to collapse.

In fact, for commercial housing, cracks will appear after a long time, which will not collapse, these are normal phenomena, probably because the foundation has changed a little bit after a long time.

Cracks in the floor slab of commercial housing are fine cracks, I personally think that it does not affect the safety of the house, and there will be no collapse, which may be just strong and not subject to certain resistance, this phenomenon is relatively normal.

Causes of cracking of concrete slabs.

1. The maintenance is not in place, and the mandatory specifications require concrete curing.

It is necessary to cover and water, most of them do not cover nowadays, and watering does not guarantee constant wetness.

2. The construction speed is too fast, and the load is early, especially the brick-concrete residential floor slab, the floor slab is poured the day before, and the brick is loaded and the car is taken the next day, resulting in early concrete damage.

3. Freeze during winter.

4. The formwork is removed too early or the rigidity of the formwork support system is not enough.

5. The slurry on the surface of the concrete is too thick, and the surface strength is not enough.

There are two main reasons for cracks in concrete floor slabs.

First, the maintenance is not timely, like the direct sunlight in summer, and the surface moisture evaporates too quickly and causes cracks.

The second is that water is added at the construction site, resulting in too much floating slurry and insufficient surface strength.

1.Longitudinal cracks: that is, cracks along the longitudinal direction of the building, mostly appearing under the slab, and some penetrate up and down.

2.Transverse cracks: that is, in the range of 1 3 in the middle of the span, the cracks along the transverse direction of the building appear mostly under the slab, and the individual runs through the upper and lower parts.

3.Corner cracks: oblique cracks that appear in the four corners of the room, predominantly in the plate epithelium.

4.Irregular cracks: Cracks that are irregularly distributed and trended.

5.Transverse cracks at the root of the floor slab: cracks created within 30 cm from the support, located in the slab epithelium.

6.Cracks that occur in the direction of the embedded conduit.

The main reasons for concrete cracks are: excessive concrete collapse, unstable formwork support system, poor concrete vibration, inadequate concrete curing, premature demoulding, and premature heavy objects!

There are many reasons for cracks in concrete floor slabs, one is the sinking of the overall building foundation, the second is that there are problems with the quality of concrete, and the third is the normal deformation cracks after a long time.

First, if it is an irregular crack and the crack is very small, it should be a concrete shrinkage crack, which is caused by the rapid shrinkage of concrete in hot weather, which does not affect the structure.

Second, if the crack is relatively large and the crack is through, it may be that the formwork support is moving, or it may be sinking.

1.There was no sprinkling in the early stage and the maintenance was good.

2.The strength of the concrete used was not up to the design value.

Four common causes of cracks in concrete building structures.

Hello, glad to answer for you. Houses with cracked floor slabs will not collapse.

Second, the crack treatment method: 1Cracks caused by temperature changes are difficult to repair, but there is no danger of a house collapsing.

In order to avoid the occurrence of such cracks, it is necessary to solve the problem by solving the difference between the line swelling of the two different materials of the roof and the brick wall. Generally, the common method is to do a good job of roof insulation. 2.

Due to the cracks caused by the insufficient stiffness of the masonry, the brick wall will show flat bending, and at the midpoint of the bending length, there are often horizontal trending cracks. In this case, reinforcement measures should be taken. Pure cement slurry can be injected into the cracks by pressure grouting, and then methods such as adding pilasters or reinforcing the walls between windows can be adopted.

3.Walls with such cracks are in danger of collapsing due to cracks caused by insufficient masonry strength. Take reinforcement measures.

Generally, it is reinforced by adding pilasters or using steel structure. 4.Due to the uneven settlement of the foundation, the cracks in the brick wall are located in different directions, and the positions and trends of the cracks caused by the lack of strength and stiffness of the wall columns are different.

That is to say, the cracks caused by the uneven subsidence of the foundation do not cause the strength or stiffness of the wall columns, and are repaired with cement mortar after the settlement is stabilized. 5.If the stiffness and strength of the wall column components and the house structure are sufficient, then the wall cracks caused by the uneven subsidence of the foundation do not need to be reinforced and reinforced, as long as the cracks are repaired.

Summary. Hello! The platform cooperation lawyer will answer for you!

Is the crack in the floor slab of the commercial house a crack that affects the safety of the house, and will it collapse? The floor slab is full of cracks, will someone be safe after moving in? Will it collapse?

Hello! The platform cooperation lawyer will answer for you!

Please tell us the details of the case you are inquiring about.

This has to be evaluated by professional housing personnel.

There will definitely still be safety hazards.

This is a problem for the developers.

If there is a problem with the quality of the house.

You can complain about the property to the Housing Authority.
