How to measure floor thickness

1, steel tape inspection method: it is to open a hole in the floor or use the reserved hole in the floor for inspection, which will cause damage to the floor, so its use is greatly restricted. This method is generally used for random sampling inspection at the site of supervision units.

2. Level detection method: use a level to measure the floor elevation of a certain point on the floor and the floor bottom elevation corresponding to that point. This method is generally used as the main method of self-inspection by the construction unit.

3. Electromagnetic principle detection method: it is a simple, convenient and accurate detection method. The error of this method is 2 mm, which is less than the ruler error mentioned in the specification, and it is applied in the acceptance of entrusted inspection institutions.

Floor thickness standard

1, common floor

The floor is an important part of the house, which can divide the building into vertical and horizontal directions. At the same time, the floor is an important load-bearing component, which not only bears its own weight, but also bears the use load of appearance. According to the national regulations, the floor thickness should not be less than 80mm, and the width should not be less than 100mm when there are concealed pipes in the floor. The thickness of the floor directly determines the quality of our living, so we should pay special attention to this problem.

2. Top floor

The top floor is the top floor of the house, with exquisite construction. The floor thickness shall not be less than12cm. Because the top floor is directly exposed, it should not only be rain-proof, heat-resistant, but also ice-resistant, so special attention should be paid to ensuring the thickness and waterproof measures during ground construction. Waterproof materials must be of good quality, not only with long service life, but also with good waterproof effect to avoid water leakage and seepage.

3, ordinary basement

High-rise buildings are equipped with basements, which can be divided into ordinary basements and emptying basements, and can be divided into full basements and semi-basements according to structure. The basement is also exquisite, and its floor thickness should not be less than 160 mm, so it is safe to use.

4, embedded parts in the basement

The embedded part is the expected part in the process of plastic hinge, which can transfer the strength of the upper structure to the lower structure and control the overall stiffness and bearing capacity, that is, horizontal translation displacement and rotational displacement. Secondly, the top cover plate of basement floor should adopt beam-slab structure, and its floor thickness should not be less than 180mm. In addition, the label of the concrete used should not be lower than C30, and the steel bars should be arranged in two directions, and the proportion of steel bars in each direction should not be less than 0.25%.
