Anonymous users2024-02-15Don't panic when you encounter this, there are many reasons for cracks in the girder, there are cracks, fracture marks, in written terms, structural cracks and non-structural cracks. There are many kinds of this, and it doesn't matter that there are many of them, and it is natural for gray to appear over time. If the girder is cracked by external force, this is called fracture, which has very serious consequences.
The longitudinal crack was in the upper part of the beam, not a fatal wound. It will not collapse violently, and the crack will be marked, so you can rest assured that you can move in, and you can usually pay attention to the observation, if the crack continues to expand and extend, people will have to move out.
But we should also know that many farmers do not do a good job when building a house, and then they start to build a wall directly, you must know that the most important thing to build a house is to stabilize the ground, because if the foundation is not strong, the house will be tilted or cracks of different degrees will appear with a period of change, and there will be cracks after the house is built in order to save labor and materials. Find the construction party, you need to rebuild, now the girder is generally poured, it is caused by improper construction, don't take life as a child's play.
Floor maintenance, after the floor is capped, the roof is maintained, and the roof is generally cast-in-situ for about a month, generally 10 days to half a month. The surface of the roof is calendered at the time of capping. If it is a prefabricated floor slab, 3-5 days is enough.
When maintaining the sprinkling, you can check whether there is a leakage on the floor, and the leaking parts should be wiped with cement mortar in time.
Compared with carbon fiber plates, carbon fiber cloth has the advantage of light weight, which is more convenient for construction. The safety of the vehicle will be affected after the girder breaks, and the welding of the girder of the regular vehicle is prohibited, because of the internal stress. Generally, the riveting process is used, and you can use rivets to connect the girder fracture after splicing with steel plates.
Be sure to use it with care in the future, do not overload, overspeed.
