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

Q:What is the relationship between the cushion and the ring beam?: Cushion is plain concrete or asphalt concrete (for groundwater soil corrosive strong site). Is located below the ground, in order to prevent the foundation or the concrete beam pouring when the excessive loss of water caused by defects set. The purpose is to ensure the quality of concrete, increase the durability of underground components

Q:What is the difference between leveling and cushion?: and only in the construction of the building at the bottom of the building, it is possible to use the relevant level of the cube, After the use of the underlying layer of the building, it is not exempt from the possibility of using leveling layer

Q:Is the raft cushion waterproofing full of the cushion?: Assuming (just suppose) the raft can easily turn over, then we do waterproof (like roof) directly on it, not waterproof on the cushion.

Q:How to build a fine stone concrete cushion?: Reduce ground cracking, plus steel mesh. Reinforced mesh, should be placed in the middle of the concrete, because the protective layer of concrete thick Fang generally only 5CM thickness, so the middle is the best.

Q:Why do the basics of the cushion waterproofing: As for the bottom of the bar thickness of the protective layer is generally 4cm, but if the basic floor of the concrete label is relatively high, the protective layer can be appropriately reduced.

Q:Basement cushion waterproof: Third, the membrane waterproof in the construction should first do the basement floor of the waterproof, and then the membrane along the basement floor continuous paste to the outer surface of the wall. Basement floor waterproofing first in the foundation pouring C10 concrete cushion, the thickness of about 100mm. And then paste the membrane, and then in the coil to wear 20 thick 1: 3 cement mortar, and finally pouring reinforced concrete floor. The outer surface of the wall first wip 20mm thick 1: 3 cement mortar, cold base oil, and then paste the membrane, the membrane should be stitched paste, adjacent coil lap width of not less than 100mm. The top of the coil should be higher than the maximum water level of about 500mm, the outer side of the brick wall.

Q:Foam concrete for the roof cushion generally do much bulk ah: in recent years, the density of 160kg / m3 ultra-light foam concrete is also used in construction projects.

Q:Cushion, waterproof layer construction to do what information: 2, bedding (bed course) refers to the structure below the grass-roots level. Its main role is to water, drainage, antifreeze to improve the grass-roots and soil-based working conditions, the water stability requirements are better. The cushion layer is a structural layer between the base layer and the soil base. When the soil quality is poor, it is used to improve the water stability of the soil base, improve the water stability and frost resistance of the pavement structure and disperse Load to reduce soil deformation.
