Construction method of free-passing super-flat floor

Abstract

The invention relates to a construction method of a free-passing super-flat floor. The construction method includes the steps of carrying out reinforcement treatment on column edges and corner edges, and arranging extruding plastic plates on wall edges; binding a plate with steel bars; processing warehouse dividing seams; paving and vibrating concrete; leveling the concrete; performing composite elevation; after the concrete leveling work is completed, spreading a wear-resistant material according to the specified dosage of the wear-resistant material; using an ultra-flat floating rule for scraping again; after initial setting of the concrete, polishing the floor; cutting shrinkage joints; and brushing an acidic mixed solution for corroding cement mortar in the shrinkage joints, removing the cement mortar in the shrinkage joints to enable coarse sand to leak out, and then filling the shrinkage joints with foam strips and a polyurethane sealant. The foam strips and the polyurethane sealant can ensure that the shrinkage joints are not influenced by external dust and the flexibility of the shrinkage joints is not influenced, and after the shrinkage joints are filled with the foam strips, the polyurethane sealant can play a good sealing effect on the shrinkage joints, so that expansion and bulging caused by influence on the flexibility of the shrinkage joints on the floor are prevented.

Description

technical field [0001] The invention relates to the technical field of floor construction, in particular to a construction method for a free-passage super-flat floor. Background technique [0002] In a broad sense, super-flat floor refers to a floor that uses a laser leveling machine or a vibrating beam to pave and level the newly poured concrete and combine certain floor construction techniques to meet a specific use requirement, such as : Large-area seamless / less seam free passage floor; in a narrow sense, it refers to the roadway area where the ground is limited to the permanent use of forklifts, and the usually applicable area is the narrow roadway directional passage and free area. [0003] In the prior art, in a Chinese patent with the invention publication number CN104612403A, a construction method of a free-passing super-flat floor is recorded, which relates to the technical field of floor construction. The construction steps are: pouring in separate warehouses, det...

Problems solved by technology

[0004] The above-mentioned existing design schemes have the following defects. Usually, during the process of filling the shrinkage joint, due to the entry of air or insufficient elasticity of the filling material, there will be a gap between the filling material and the shrinkage joint, and the filling material cannot be fixed well. in the shrinkage
