- Q:Basement cushion waterproof
- Five, how the basement moisture:
1, moisture-proof material
This is the decoration in the attention of the problem, the basement is relatively humid place, so when we should pay attention to the decoration, the choice of wallpaper, tiles and other moisture-proof effect of better decoration materials, and other basement ceiling, floor, walls are To be the best waterproof.
2, ventilation and moisture
Strengthen the air circulation on the moisture is more helpful, can effectively reduce the indoor moisture content.
3, electrical dehumidification
If you run into the rainy weather, outdoor air humidity is relatively high, it is not suitable for long ventilation, you can use the exhaust fan, air conditioning or dehumidifier and other machines for indoor dehumidification.
4, desiccant dehumidification
In addition to the use of a variety of electrical dehumidification can also be placed some moisture damp dehumidification effect of small items, such as desiccant, charcoal and other indoor moisture, but the desiccant is a service life, the general need for frequent replacement.
5, to warm moisture
Installation of warmth is also one of the effective means of underground moisture protection, to warm the basement room temperature can be maintained at a certain temperature can keep the room dry and not wet, but pay attention to the temperature is not too high will cause the room is too dry, Comfortable.
- Q:Maintenance time of the cushion on the roof of the building
- According to the "concrete structure construction quality acceptance criteria" provides:
Concrete should be poured within 12h after the completion of the concrete to be covered, and moisturizing conservation;
- Q:Cushion, waterproof layer construction to do what information
- 3, waterproof layer: In order to prevent the rain into the roof, groundwater into the wall, basement and underground structures, indoor water into the floor and walls and other materials layer.
- 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:What is the relationship between the cushion and the ring beam?
- Ring beam is reinforced concrete. Is to increase the overall wall and overall stiffness, improve the side resistance performance, according to the earthquake or masonry specifications set. There may be in the ground wall, there may be in the underground wall.
- Q:Is it possible to make a waterproof layer
- 2, waterproof layer: In order to prevent the rain into the roof, groundwater into the wall, basement and underground structures, indoor water into the floor and walls and other materials layer.
- 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:Can the floor tiles be removed from the cement mats on the prefabricated board floor?
- Prefabricated board floor layer of cement layer is not called the cushion, should be called leveling layer, this layer can be eradicated, but should pay attention not to damage.
- Q:Is foam concrete suitable for use as a cushion?
- And then through the foaming machine pumping system for cast-in-place construction or mold forming, the formation of natural conservation with a large number of closed pores of the new lightweight insulation materials.
- 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.
