Embodiment Construction

[0019] In the embodiment, the load-bearing column 3 is a cylinder after the original pile 2 is reinforced, and the radius of the load-bearing column 3 is 120-300 mm longer than that of the original pile 2, that is, the width of the reinforced annular concrete 12 in the load-bearing column 3 is 120-300 mm. The reinforcement bars 10 of the reinforced annular concrete 12 in the load-bearing column 3 adopt steel bars with a diameter of 22-25 mm, and the distance between adjacent load-bearing columns 3 is 3.5-6 mm; The cross-sectional area is the same or the difference is less than 10%; the basement floor 4 has a thickness of 400-550 mm, and the basement floor 4 is provided with shear reinforcement 9 at the position of the load-bearing column 3. The diameter of the shear reinforcement 9 is 32-35 mm, and the shape of the shear reinforcement 9 is a horse. Stool shape. Set the water-stop rubber ring 5 on the outer surface of the original pile 2 in the concrete floor. The water-stop ru...

Abstract

The invention discloses a basement reconstruction structure with a raft foundation building. The basement reconstruction structure is characterized in that original piles are used as basement force bearing columns, part piles of a basement are removed, the original piles are reinforced to form the force bearing columns, and effective connection is conducted between the bearing columns and the original piles through special connection structures. The basement floor is provided with shear resistant ribs in the positions of the force bearing columns, and the shear resistant ribs are in a horse stool shape. Watertight rubber rings are arranged on the outer surfaces of the original piles and in the concrete floor, and the watertight rubber rings are arranged in the middle of the concrete floor. Annular watertight grooves are formed along the outer surfaces of the original piles and embedded into the watertight rubber rings. Polyurethane waterproof mortar is arranged on the concrete floor. The basement reconstruction structure is good in structural behavior, safe and reliable.

Description

technical field [0001] The invention relates to a basement transformation method, in particular to a basement transformation structure of a building with a raft foundation. Background technique [0002] With the development of the city, the difficulty of parking has become a problem that plagues the common people. It is necessary to renovate some buildings that have the conditions for remodeling and reset the basement. For buildings with raft foundations, the piles are arranged under the raft foundation in the basement reconstruction structure, and the pile spacing is relatively dense. The pile spacing is generally between 1.8 and 2.5mm, and these piles are the main vertical load-bearing components. How to ensure the safety of the building and ensure the function of the basement is a problem that engineers must face. Contents of the invention [0003] The invention provides a basement renovation structure of a building with a raft foundation, which solves the problem of ...
