Mr. Wang, the owner: “The air-conditioning installation company installed central air-conditioning during the renovation of my home. The construction staff did not fully understand our housing structure and randomly drilled holes in the main beam, resulting in a diameter of 30×22cm. hit the lower part of the main beam diameter of 15 cm two holes. tendon rupture resulting in the end of the main beam. how can we do? "
Solution: After our on-site survey, the bottom beam of Mr. Wang's home was not only subjected to the entire main beam force, but also to the housing structure. Now the bottom beam of the main beam is broken, and it must be reinforced again. At present, the air-conditioning installation company has commissioned a professional architectural design company to carry out the design of the reinforcement plan, and then ask the professional reinforcement company to carry out beam reinforcement. Even if the results of such treatment eliminate hidden dangers and dangers, it still greatly affects the overall decorating effect. Therefore, to remind the owners: Cross beams must be very careful! Avoid serious consequences.
The main beam hole must be cautious
At present, more and more decoration owners have chosen to install central air conditioning and floor heating. However, the installation of central air conditioning and floor heating has very professional technical requirements. Especially in central air-conditioning, in the installation of indoor units and fan coils, it is sometimes necessary to make holes in the beams so that they can be worn smoothly. However, there are strict requirements for hole punching, because any hole in the beam will damage the beam's stress function.
and so,
First, we can not make holes and be resolutely not easy to fight;
Secondly, a hole with a small diameter cannot hit a hole with a large diameter so as not to cause greater damage to the beam.
Third, in general, the hole must be hit in the middle of the beam, because the upper and lower parts of a beam are the main tendons where the main force is placed, that is, the locations where the thick steel bars are fixed in the concrete beam. Holes should not hurt the main tendons, especially the main tendons. Once the main ribs are broken, the load and the load of the beam cannot basically be exerted. It will take a long time for the beams to break and cause great hidden dangers and dangers.
