Description

Technical Field

[0001] The invention relates to the technical field of building decoration construction, and in particular to a large-area floor construction method without seam cutting, and in particular to a large-area floor construction method without post-cutting and with high construction efficiency. Background Art

[0002] Large-scale floor construction will occur in basement garages, factory floors and other places. The floor base is basically reinforced concrete, and the most common surface materials are corundum, epoxy self-leveling, and cement-based self-leveling. In order to prevent concrete shrinkage and cracks during reinforced concrete base construction, expansion joints are generally cut after the concrete is cast. Specifically, after a large area of ​​concrete is cast, the joints are generally cut every 2-3 days. The spacing between expansion joints is generally not more than 6m×6m, the joint width is 3-5mm, and the joint depth is 1 / 3 to 1 / 2 of the floor thickness. Before cutting, the lines are drawn first, and then the joints are cut with a cutting machine. Small cutting machines are used for parts with insufficient operating surfaces. Traditional joint cutting not only has the possibility of not cutting straight, but also produces sewage during the cutting process, polluting the floor. At the same time, it is difficult to cut the position close to the wall, and there is a problem of inflexible operation.

[0003] Therefore, it is of great practical significance to develop a large-area floor construction method that does not require post-cutting, is simple to operate, has high construction efficiency and low overall cost. Summary of the invention

[0004] Due to the above-mentioned defects in the prior art, the present invention provides a large-area floor construction method that does not require subsequent cutting, is simple to operate, has high construction efficiency and low overall cost, thereby overcoming the defects of large-area floor construction cutting, such as low construction efficiency, high overall cost and inconvenient operation.

[0005] A large-area floor cutting-free construction method comprises the following steps:

[0006] (1) For large-area floor, all sections are divided into construction section 1 and construction section 2. The skipping section method is used for pouring construction, and expansion cracks are reduced through construction measures;

[0007] (2) Formwork and concrete pouring shall be carried out according to the compartment sections, and adjacent compartment sections shall be poured at different times;

[0008] (3) After completing the construction of the first floor, stick a sponge strip on the upper part of the concrete side, and then pour the second floor concrete.

[0009] The present invention provides a large-area floor cutting-free construction method, which adopts the skipping bin construction method to greatly reduce concrete expansion cracks. At the same time, it is coordinated with sponge strips, and the sponge strips are used as occupiers at the cutting joints. After the concrete pouring is completed, adjacent floors are connected by sponge strips, which can play the role of expansion joints. The anti-cracking effect is significant, and there is no need for subsequent cutting. Compared with the traditional cutting process, the operation is greatly simplified, the construction efficiency is greatly improved, the overall cost is reduced, and the application prospect is good.

[0010] As the preferred technical solution:

[0011] In the large-area floor cutting-free construction method as described above, the compartment seams of the compartments are no larger than 6m×6m.

[0012] In the large-area floor cutting-free construction method as described above, the height of the sponge strip is 1 / 3 to 1 / 2 of the floor thickness.

[0013] In the large-area floor cutting-free construction method as described above, the compartment division is completed according to the column spacing.

[0014] In the large-area floor cutting-free construction method as described above, the thickness of the sponge strip is equal to the seam width, which is 5 mm.

[0015] The above technical solution is only a feasible technical solution of the present invention, and the protection scope of the present invention is not limited thereto. Those skilled in the art can reasonably adjust the specific design according to actual needs.
