Technical Field
The invention relates to the field of repairing construction of original buildings, in particular to a floor slab inclination treatment construction method.
Background
In the field of building construction, uneven settlement of independent foundation house buildings is unavoidable, and the floor is inclined. Or local tilting of the floor at the business of the affiliated business site of the residential building? At present, the phenomenon of poor appearance and even unqualified quality caused by the inclination of a missing floor slab is eliminated by plastering in the market. The phenomenon of poor comfort and poor look and feel caused by the inclination of the structure is eliminated through the suspended ceiling. In general, if plastering is adopted to eliminate the uneven condition of the floor slab, the effect is obvious only within 30mm of error. If the deviation is too large, the uneven condition of the floor is treated by adopting a plastering process, the plastering layer of the top plate is easy to fall off, so that a huge potential safety hazard is left, and the plastering thickness is not suitable to be larger than 50 mm. If the conventional PVC suspended ceiling is adopted to conceal or improve the impression error brought by the inclination of the floor slab, the appearance error is only treated but not treated, and the phenomenon of the inclination of the floor slab is still present and is only shielded, so that the problem is not thoroughly solved. And deformation in a certain range can be generated along with the settlement of the foundation, so that the deepening inclination image is enlarged. Under the background, the project group and the company invent a whole set of technical scheme by combining multiple researches and demonstrations and field practice, and the technical scheme is used for solving the problem of impression and potential safety hazard caused by floor inclination.

(5) Binding reinforcing steel meshes on the lifting hook expansion bolts, wherein the distance is 150x150mm, and the reinforcing steel meshes are firmly bound by adopting 18# binding wires and penetrate through holes reserved in the section steel in the step (3);
(6) The template is supported, and a hall-filling support frame is supported by a 15mm thick multilayer plate and a fastener type steel pipe scaffold;
(7) Pouring concrete, namely picking and chiseling a plurality of evenly distributed holes on the upper part of the original structure floor slab, pouring by adopting C35 fine stone concrete and doping a micro-expanding agent, and vibrating;
(8) Removing the mould after the strength reaches 100%, and sprinkling water for curing for 14 days;
(9) And (3) ground part treatment: if the ground is inclined, directly picking and chiseling concrete on the inclined part of the ground, cleaning up, and re-constructing; if the two or more floors are inclined, pouring a layer of concrete again directly on the upper part for leveling the floors.

The method has the advantages that the correction and maintenance are carried out by adopting the chiseling and breaking method when the existing engineering floor slab is constructed or quality problems occur in later period, time and labor are consumed, the cost and labor are also high, meanwhile, the original floor slab structure can be damaged in an unrepairable way by chiseling, the stress condition of the original floor slab is damaged, and the integrity of the engineering structure is greatly reduced.
The technical method of the invention is equivalent to creatively applying the existing state of the original structure under the condition of the original quality defect, does not influence the stress and the integrity of the structure, and reinforces and applies a layer of steel reinforced concrete floor structure at the original floor quality defect part. Not only repairing the quality defect of the floor slab, but also improving the appearance of the floor slab. Meanwhile, the requirements of using functions are completely met.
In the repairing process, if the span is too large, the repairing area is large, and the section steel concrete column structure can be arranged at the shear wall or the frame column part and used for supporting the upper part to increase the load weight of the section steel concrete floor slab. For example, a ring of steel reinforced concrete un structure with the width of 300mm is arranged on the periphery of the original concrete frame column with the span of 4m multiplied by 4 m. The upper part can bear the load weight of the reinforced concrete structure floor slab with the thickness of 200 mm.
