Miniature cracks in the beams of the house do not affect the load-bearing of the beams. According to the design code, the concrete beam is allowed to have micro-cracks. You can use putty to close the cracks, and then brush the paint to prevent the beam steel bars from rusting.
-
There are very fine cracks in the beams of the house, and the cracks are very fine and fine, which basically will not cause damage to the structure of the house, so it is good to deal with it a little. If you suspect that the crack has a certain impact on the house, then find someone to repair and reinforce it.
-
If there is a crack in the girder of the house, then repair it quickly, although the crack is very small, it should also be repaired in time, otherwise this girder is very important and easy to collapse.
-
If there are cracks in only one layer, the cracks between the board and the wall are scattered and not connected, and the cracks are not penetrated, then it may be the cracking of the plastering layer, which belongs to the quality problem of the house decoration item; If the crack is long or penetrates, it may be a local structural quality problem. These two problems can still ensure the safety of the main body of the house after repairing or strengthening treatment.
-
There is a crack in the girder of the house, and it should not matter if the crack is very thin, you only need to go through the crack through the later subsidy.
-
In this case, I should find a professional master to wipe the cracks with cement, so that the house will be stronger and will not fall safely.
-
For the girders of the house, there is also an interest rate, so hurry up and repair it, after all, the girder is the main support point, which is easy to cause landslides.
-
What should I do if there is a crack in the girder of my house, the crack is very small, you can call his decorator to help you fix it.
-
It depends on what kind of house you are, and the building is different from what you built.
Second, you have to send it over to see the location and nature of the crack.
Third, when it will appear and what will be the state of development.
And then you can judge.
-
It is recommended to find a security worker to take a look.
If there is a safety hazard, it should be solved as soon as possible.

Summary. Dear, I am happy to answer for you: the concrete beam is a little slight crack problem, the serious general load-bearing beam is very strong, and the type of steel bar and concrete are very particular, after the general concrete is poured, compaction is carried out to wait for the solidification of the concrete, and finally the removal of the mold This series of processes are very rigorous, and will also take into account weather factors.
Therefore, the concrete itself has a certain elasticity, and this kind of crack will generally not occur. If there are slight small cracks, but the intermittent kind may not have much impact on the load-bearing, because due to the weather, due to humidity, due to the material of the concrete, etc., there will be a little such cracks, as a construction unit will also deal with these cracks, of course, there will be inspectors to test.

Vertical cracks appear when the strength is reached.
1. The solution to the cracking of the load-bearing beam is to strengthen it in advance. The common reinforcement methods for general house reinforcement include pasting Hummer carbon fiber cloth reinforcement, steel reinforcement, prestressed carbon plate reinforcement and other ridge reinforcement methods. 2. If there are slight vertical cracks in the load-bearing beam, it is generally caused by bending failure.
If there are fewer reinforcements in the joists, the masonry strength is higher, and the wall height span is relatively small, then the vertical cover crack will appear first in the middle span of the wall beam under the vertical load. 3. The vertical cracks extend rapidly upward with the increase of load, and continue to expand upwards after entering the wall, and the vertical cracks in the joist continue to appear. When the reinforcement of the main crack section of the joist reaches the yield limit, the wall beam undergoes bending failure.
-
1. Improper construction operation makes the position of the negative reinforcement of the bearing fall, the protective layer of the reinforcement is too large, and the fixed bearing becomes a plastic hinge, which is easy to cause long cracks along the beam edge of the plate surface; 2. In the pouring process, the concrete tamping vibration is uneven, and the area of the repentance stove is missed, resulting in an undense area inside the beam and plate, and eventually causing cracks. 3. The thickness of the protective layer on the surface of the beam plate is not up to standard, which causes the steel bars in the beam plate to be easily corroded and the volume expansion occurs, which will induce the occurrence of longitudinal cracks in the beam plate.

Hello dear and happy to answer for you. Crack measures in the beams of the building :1
We can remove about 10 mm on both sides of the crack to make the crack V-shaped, and rinse the crack with water; Next, the epoxy resin repair material is configured and poured into the crack, and the surface of the tear is smoothed and then covered with mesh cloth for reinforcement; Finally, the beam can be painted. 2.If the beam is due to a mistake in the reinforcement configuration, or because the formwork removal time is too early, or because of the cracks caused by the foundation subsidence, these cracks will usually have a certain impact on the quality of the beam, you can ask professionals to reinforce the beam, or we will knock out the unqualified beam and redo the beam.
Hope mine is helpful to you! Don't forget to give it a thumbs up! I wish you a happy life, peace and joy!

Summary. It would be better if you could give the span (length), girder size, concrete grade, reinforcement of the girder? Attach a **?
In this way, the cause of beam cracking can be more accurately determined, because there are many reasons for beam cracking: 1. Cracking caused by insufficient strength grade, 2. Cracking of less reinforced beams, 3. Cracking caused by premature demoulding, 4. Shrinkage cracking of concrete caused by uncured maintenance, 5. Cracking caused by excessive load on the upper part, and the cracking remediation caused by each situation is also different: except for the 4th kind, the original pulp can be used to repair the joints.
Other remedies are a bit complicated, generally using carbon fiber reinforcement (high cost), reinforcement, angle steel reinforcement (commonly used), special structural adhesive reinforcement, etc.

7 meters, 5 meters, 6 meters, a total of 18 meters. One, two, three layers are C30, four, five and six are C25, 20x60 beams, bottom 3 surface 2 is 18 steel bars, and the middle 14 steel bars.
This kind of comparison is more difficult, and it requires manpower and material resources.
This will only be the case on the sixth floor, will this be a problem for the safety of the house?
**Look at this is just a coating.
Do you want to have it repaired? If there is no deformation, there is no need.

Summary. It is relatively normal for the beam to have subtle cracks, which may be caused by construction, which is too dry during construction, and it is easy to crack in the later stage.
It is relatively normal for the transverse spike skin beam to have subtle cracks and lead calling, which may be caused by construction, which is too dry during construction, and it is easy to crack the Huai clan Kai crack in the later stage.
Of course, if it is only a subtle crack, then the impact is not particularly large, but it is not excluded that this crack will expand, and we still have to find out what the specific reason is, it may be because of the sinking of the foundation of Hail.
In addition, you should also pay attention to the possibility of water leakage after the crack in the beam, and it is best to find a professional organization to judge the specific situation.
I wish you a happy life, dear, thank you for your question, give a thumbs up for your help, thank you.
Are there a few fine lines that are broken beams, and is the problem serious?
It's not too big, it's normal, it's okay.
It's not going to break.
No. There are a few fine lines at the bottom of the girder, extending two centimeters upwards.
It's okay, as long as it's not too big, it's fine.
It is the fine lines that the tip of the needle can't be inserted, afraid that it will fall down, hollow five meters, five twenty-five steel bars, two eighteen steel bars, two twelve steel bars.
You ask about this property, pro specific.
1. Replacing the girder, of course, can make the car meet the requirements of use, but this repair method has a long maintenance time, often several days and dozens of days. The repair cost of replacing the girder is high, often thousands of yuan and tens of thousands of yuan. In particular, delays are often costly and unacceptable, so the replacement of girders is generally excluded. >>>More
Remove the crack-proof putty that was originally cracked. Re-patch the seam with anti-crack putty and then apply it with gauze or kraft paper. I recommend that it is best to use kraft paper, and also, the putty used for repairing joints should not be made of gypsum powder, and some people use it for the convenience of construction and saving money. >>>More
The treatment method for cracks caused by the lap of the mesh cloth is to remove the plastering mortar layer until the mesh cloth that is not lapped in place is completely exposed, and then re-embed the mesh cloth with flexible plastering mortar, so that the lap of the newly pasted mesh cloth and the original mesh cloth must be more than 8 cm on each side, and the flexible plastering mortar must completely cover the mesh cloth, and keep the flatness of the renovated surface and the old wall; Clean the wall, along the width of the crack part about 5 cm, directly roll the anti-crack waterproof adhesive, and press into the middle of the ultra-thin reinforced anti-crack cloth. With the acceleration of the development of external wall thermal insulation and the immaturity of technology, there is a phenomenon of falling off the external wall thermal insulation board, hollowing, cracking and water seepage of the external finish. The leakage of the outer protective layer seriously affects the thermal insulation performance of the insulation material, and may damage the structure of the outer protective layer, and at the same time, the existence, movement and freeze-thaw of water will also promote the deterioration of the wall structural material, induce the cracking of the wall, and lead to the basic leakage of the outer wall. >>>More
After the house is handed over, it is necessary to carry out a house inspection, and the house inspection finds quality problems such as cracks in the house, how to make the developer compensate? What if there are cracks in the house after a home inspection? Generally, the compensation shall be borne by the developer, and the legal route should be taken if the situation is more complicated. >>>More
The wall cracks caused by the cracking of the structural layer of the wall itself generally include two conditions, the first is that the original wall itself has cracks, and no appropriate treatment methods are taken in the later decoration process; The second is that the original wall has no cracks during decoration, but cracks occur in the later stage due to uneven foundation settlement and large temperature changes. >>>More
