Architectural terms I

1. raft foundation: the upper load is large, the foundation bearing capacity is low, the general foundation can not meet, the foundation can be expanded into support the whole building structure of the large reinforced concrete plate, which has become cutting foundation or cutting foundation. Cutting slab foundation can not only reduce the unit area pressure of foundation soil, improve the bearing capacity, but also enhance the foundation stiffness, adjust the uneven settlement, so it is widely used in multi-storey and high-rise buildings.

2. brick mold (also known as temporary retaining wall) : brick mold is generally used in the basement floor side wall, because it is waterproof, must be waterproof on the cushion, and waterproof to extend to the brick membrane, so that after pouring concrete, waterproof can be turned over to the side wall concrete, if the bottom wall with template, can not do waterproof, so the use of brick template method. In addition, in some places where the formwork cannot be removed after pouring concrete or where it is very difficult to remove, there are also ways to use brick instead of a general formwork.

3. Post-pouring belt: Post-casting belt is in construction, in order to prevent the harmful cracks of cast-in-place reinforced concrete structure due to the uneven temperature and shrinkage, according to the requirements of the design and construction specifications, temporary construction joints are set up in the corresponding position of the foundation plate, wall and beam, the structure is temporarily divided and dry part, after the construction of internal shrinkage, in a number of time (generally 28 days) after pouring the construction joint concrete, Link the structure together. The spacing of the post-pouring belt should be reasonable. The spacing of the post-pouring belt of rectangular structures can be set to 30 ~ 40 meters. The width of the post-pouring belt should be considered to facilitate the construction operation, and should be determined according to the structural requirements.

4. construction joint: in the process of concrete pouring, due to the design requirements or construction needs to be piecewise pouring, and the joint formed between the first and the second pouring concrete.

5. cap: refers to the load for bearing, distribution by the pier transfer, set at the top of the foundation pile connecting the pile top of the reinforced concrete platform.

6. pile foundation: pile foundation is composed of pile foundation and connected to the top cap, is a foundation that connects the top of several single piles sunk into the soil with the cap. The role of pile is to transfer the load of the upper building to the deep soil layer with large bearing capacity, or to compress the weak soil layer to improve the bearing capacity and compactness of the foundation.

7. anti-floating bolt: refers to the resistance to building upward displacement of various pile type general name, anti-floating bolt is different from the general foundation pile, has its own unique performance, anti-floating pile for pulling pile.
