Q: The cushion is usually in the housing which parts: There was no other place in the house below

Q: When the cushion is used, the thickness of the protective layer is not less than (): Master roof: the general use of 40 thick C20 reinforced fine stone concrete protection.

Q: Why do the basics of the cushion waterproofing: The general basis of the foundation, the bar base is not necessary to do, like a raft in the basement, it is necessary to prevent the water from dipping into the basement (so the basement design may have to do anti-floating calculations). Assuming (just suppose) the raft can easily turn over, then we do waterproof (like roof) directly on it, not waterproof on the cushion.

Q: The top floor made waterproof playing cushion layer of how to do: 2. repair the cracks well. After the cracks to be repaired are dry, start waterproofing.

Q: Basement cushion waterproof: Fourth, improve the waterproof performance: 1, Aggregate graded concrete, is the use of different aggregates of the aggregate and improve the content of cement mortar in the concrete, so that the mortar is filled between the aggregate, thus blocking the aggregate is not dense between the seepage channel , Improve water resistance; 2, plus concrete, is added in the concrete air conditioner or dense agent to improve the impermeability.

Q: Can the floor tiles be removed from the cement mats on the prefabricated board floor?: You can dig, but be careful not to use a strong earthquake with the machinery to remove, otherwise it will damage the original structure.

Q: What is the difference between leveling and cushion?: Building floor cushion is the structure layer below the grass-roots level. Cushion as the name suggests is the structure of the liner layer, mainly plays the role of the back cover. Cushion should be noted with the basic distinction. It is easy to confuse the two engineering concepts.

Q: Large area ground concrete cushion seam Why is the separation of joints generally concrete: hird, the relevant parts Different types of rigid waterproof layer separation spacing in addition to meet the calculation needs, but also in the following parts set sub-grid joints. 1. The deformation of the roof structure sensitive parts; 2. Roof and roof drainage direction changes; 3. The junction of the waterproofing layer and the protruding roof structure; 4. Under normal circumstances, each bay load-bearing walls should be set sub-grid seam. 5. Between the waterproof layer and the load-bearing or non-load-bearing parapet or gable should be set sub-grid joints, and in the node structure for proper treatment.

Q: How to build a fine stone concrete cushion?: The cushion is primarily responsible for the load coming from the surface and passes the load evenly to the structural or base.

Q: Why calculate the amount of time to count a lot of cushion ah: ? In the municipal engineering, the bedding layer is a structural layer between the grassroots and the soil foundation. When the soil temperature is bad, the water temperature of the soil is improved and the water stability and frost resistance of the pavement structure are improved. Diffusible load to reduce soil deformation.
