Embodiment Construction
[0031] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0032] Such as figure 1 As shown, the present invention provides a structural beam modification and reinforcement method, comprising:
[0033] In step S1, the non-frame beams and slabs around the structural beams to be transformed are reinforced with bent frames, so as to increase the bearing capacity around the structural beams to be transformed;
[0034] Step S2, cutting the structural beam to reduce the height of the structural beam, the cut height is no more than 50% of the original height of the structural beam, such as 25%-45%, specifically, figure 1 Middle a is the part to be cut of the structural beam;
[0035] Step S3, using the floor slabs on one or both sides of the structural beam as the beam to be connected, chiseli...

The invention provides a structural beam reconstruction and reinforcement method. The structural beam reconstruction and reinforcement method comprises the following steps of reinforcing a framed bent of non-framed-beams and plates at the periphery of a to-be-reconstructed structural beam; cutting the structural beams to reduce the height of the structural beams; scabbling surfaces of the structural beams with height being reduced and the surfaces of to-be-connected floors on the single side or bilateral sides of the structural beams and striping out a beam plate main steel bar; increasing embedded steel bars on the single side or bilateral sides of the structural beams with height being reduced; increasing a beam main steel bar and a beam and plate penetrating hooping between the structural beam with the height being reduced and a to-be-connected beam; arranging a new beam template between the structural beam with the height being reduced and the to-be-reduced beam and forming into a new beam by pouring grouting materials inside a new beam template. The structural beam reconstruction and reinforcement method can be applied to reconstruction of a built structure, solves the problem that the indoor clear height of an old structure cannot satisfy a building functional requirement and satisfies the requirement for the indoor building clear height and meanwhile guarantees the security and stability of a reconstructed structure due to reconstruction and reinforcement of the structural beam.
Description
technical field [0001] The invention relates to a method for reforming and strengthening structural beams. Background technique [0002] In the renovation of existing buildings, there are usually the following methods to increase the indoor clear height: do not carry out large-area suspended ceilings, stretch the spatial layering of the suspended ceilings, and improve the visual height of the space; do not raise the ground, use laminated floors or Brick. However, these methods do not increase the structural height in a practical sense or increase the indoor height of the building to a very limited extent, which cannot meet the requirements of renovation. Therefore, there is an urgent need for a structural beam modification and reinforcement method to effectively increase the indoor height of a building. Contents of the invention [0003] The object of the present invention is to provide a structural beam reconstruction and reinforcement method, which can solve the proble...
