Problems solved by technology

[0002] Prestressing is widely used in the field of bridges and has been maturely applied, but this technology has not been applied to buildings
The multi-layer cantilevered beam-slab structure with prestressed suspension inside the external tube is a new structural form, which is different from the usual prestressed concrete structure. Its construction technology is very difficult, and some construction technical parameters need to be studied. It still needs to be discussed, such as construction process, joint structure, tension value, tension timing, construction control method, etc. For the construction of this structure, there are no technical regulations to follow, and no technical information for reference

Embodiment Construction

[0112] In order to further describe the characteristics and advantages of the present invention, the following in conjunction with examples:

[0113] Material

[0114] Unbonded prestressed steel strands: Unbonded steel strands are made of steel strands in accordance with the requirements of the technical standard "Unbonded Steel Strand Prestressed Tendons". Visually inspect the thickness of the non-adhesive plastic wrapping layer (high-density polyethylene), the fullness and uniformity of oiling, etc.

[0115] Prestressed anchorage: the anchorage adopts clip anchors, and the anchorage shall have the manufacturer's certificate of qualification when it enters the site. Its performance should comply with the relevant provisions of the current national standard "Anchors, Clamps and Connectors for Prestressed Tendons" GB / T 14370. Hardness inspection should meet the requirements, anchoring efficiency coefficient: η a ≥0.95, total strain at ultimate tension: ε apu. ≥2.0%, it can ...

Description

technical field [0001] The invention relates to a building construction method, in particular to a prestressed construction method for a multi-storey building. Background technique [0002] Prestressing is widely used in the field of bridges and has been maturely applied, but this technology has not been applied to buildings. The multi-layer cantilevered beam-slab structure with prestressed suspension inside the external tube is a new structural form, which is different from the usual prestressed concrete structure. Its construction technology is very difficult, and some construction technical parameters need to be studied. It still needs to be discussed, such as construction process, joint structure, tension value, tension timing, construction control method, etc. For the construction of this structure, there are no technical regulations to follow, and no technical data for reference.
