楼板切割，怪不得房子隔音效果不好

🙂

楼板切割确实影响隔音，但施工质量才是根本。便宜的承包商往往偷工减料，隔音垫铺设不足才是主因。

切楼板本身不是原罪，没做减振和浮筑才害人。标准做法：周边断振缝，弹性隔音垫配浮筑层，穿板管线用套管并弹性封堵，边界避免刚性连接，完工做撞击声测试。缺一项，楼板就变声桥，脚步声低频一路直灌，最后还是业主买单

Coming from Asia and living in Europe and the U.S., one thing I’ve never understood is why construction quality in the U.S. often seems so poor. Look at the flooring, the reinforcement rods, their density, and the overall materials used. Compare that to even middle-class homes in Asia—where they use deep piling (sometimes 50 meters even for a 3-story building), thicker concrete floors, and significantly more robust construction overall. Now compare that to houses in places like Florida or California—even high-end mansions. The amount of concrete, reinforcement, and overall structural solidity often feels minimal. In New York, some buildings also seem questionable in terms of floor thickness and reinforcement—it honestly feels like a compromise on quality. Why is this the case? Are construction standards, materials, or practices fundamentally different? I’d genuinely like to hear from someone with civil engineering expertise in the U.S. My own experience hasn’t been great either—lightweight materials, drywall (“false walls”), and what feels like low-durability construction. Sometimes it feels like these walls wouldn’t withstand even minor force. Why are homes built this way? In Europe, where winters are longer and harsher, buildings often feel much more solid and durable. Materials seem significantly better. Even friends from Asia joke about U.S. homes—calling them “plastic houses” with glued materials and shingle roofs that cost a fortune. Why is the housing system designed this way? Even if you’re willing to spend more, it’s hard to find builders who truly understand or deliver the kind of solid construction you see in many parts of Asia.

@lmqlai 谢谢分享！

这是要安装楼梯吗？

有可能哦

现在的高层建筑基本上都是空心砖，比原来的六层楼，建筑隔音效果差很多

哦

看每个房子质量吧 我家还好 😂

☺️

危险啊

嗯

zero rebar, or is it my imagination

That's just the concrete slab! Normally, an insulation layer is laid on top of it and a floating screed is applied, which significantly improves sound insulation.

明白了😊

Está excelente esa losa. Tenés que ver lo que hay en el Conurbano Bonaerense. Eso es un lujo.

😀谢谢分享！

早安心怡🌹🌹🌹

早安😊

👍🏻👍🏻👍🏻

焦點原來不是只有一條鋼筋😨

😊

楼上装修硬生生把地板给挂了几公分可以投诉到物业

😄

这打楼板的半分钟视频，三百多万次流量？！无语凝噎……

Very risky work

嗯

The slap doesn't look very thick and strong

😊

🤌🤌

床スラブは220mmは最低欲しいし静かでありたいなら300mmを希望します。 120mmのアパートはとてもうるさいし、軽量化された空洞スポンジを含むとよくない結果がありました。

floors can't lie 🤣 but sometimes they do when it's a thin 2" slab vs the recommended 4". poor sound insulation is real, especially in budget cuts. fr, maybe the devs were on a tight schedule? #builderproblems 😅

🤣🤣

No wonder

😎

That’s real luxury

😊

👌👍

Daha Bunun üstüne şap dökülecek

哦

@grok please explain this

どういう設計なんだこれｗ

这是要上下打通？看来房主有实力

不晓得这是要干啥

厚度明显不够 而且没有隔音层 真是省到极致了

😃

なるほど…これじゃ防音効かないのも納得だわ😳💀

@Hadji_El_24 😊

😊その笑顔…絶対わかってたでしょ😭💀
