Will the expansion screws hit the upstairs floor slab and cause water leakage when the ceiling is ma

Hello dear, <>

Will the screws of the upstairs sedan car hit the upstairs and the floor slabs downstairs causing water leakage? No, the thickness of the general floor is 15 cm, and the expansion screws here are at most 5 cm deep, so it will not be the first to see whether it is a prefabricated board or a cast-in-place board, the prefabricated board is easy to be empty, the cast-in-place board is fine, play in the bathroom, be careful not to hit too deep, avoid breaking the waterproof of the previous layer, generally no problem. The expansion screw is composed of components such as a screw and an expansion tube, the tail of the screw is conical, and the inner diameter of the conical sail is larger than the inner diameter of the expansion tube.

When the nut is tightened, the screw moves outward, and the cone part moves through the axial movement of the thread, and then forms a great positive pressure on the outer surface of the slag of the expansion pipe, and the angle of the cone is very small, so that the friction self-locking between the wall, the expansion pipe and the cone is formed, and then the fixing effect is achieved.

This question is really ......

If the expansion screw is very long and the hole is very deep, it may penetrate the floor slab upstairs....Specialized....If the water pipe or heating pipe leaks, it will leak ......If you live downstairs, this issue must be taken very seriously! Pay more attention when you work.

If you live upstairs, it doesn't matter......The trouble caused downstairs, even if the water leaked, it was leaking to his house, and he had to take responsibility for ...... himselfThis matter, he will definitely deal with it as soon as possible......

Hello, the downstairs ceiling expansion bolts will not hit the upstairs floor slab leakage. Because the hole cannot be punched so deep, the floor slab is not so thick, and the master has a number of screw holes.

Generally, no, the floor slab is not that thin.

Reinforced concrete floor slab + plastering, not less than 100mm thickness, expansion bolt as far as possible not to exceed 60mm (punching depth not to exceed 70mm), the most important thing is that the electric hammer construction workers must pay attention, do not drill too much, if you penetrate the floor, there will be a risk of hurting the floor heating pipe.

It depends on the depth of the bolt hole, the depth of the hole will destroy the waterproof layer upstairs, the general depth is not more than 6cm, generally will not hurt the waterproof upstairs, and then it is not necessarily.
