Description

Technical Field

[0001] The invention relates to the technical field of civil engineering construction, in particular to a concrete partition joint sealing construction method. Background Art

[0002] With the development of modern construction industry, concrete has become one of the most important civil engineering materials in contemporary times, and is often used in the construction of concrete structures, building ground engineering, and roofing engineering. However, due to the poor crack resistance and low tensile strength of concrete materials, cracks are prone to occur, especially in the construction of concrete ground surface layer, roof leveling, slope sizing, and protective layer construction, coupled with the concrete's own shrinkage and temperature differences, cracks are very likely to occur during the later use process.

[0003] During the construction of the roof fine stone concrete protective layer, in order to avoid cracking of the protective layer, expansion joints should be set. The expansion joints are generally caulked with asphalt paste. The asphalt paste caulking material itself has good film-forming properties, impermeability, aging resistance, and corrosion resistance. However, it is easy to separate from the concrete at low temperatures, easy to flow at high temperatures, and easy to volatilize under exposure, resulting in poor straightness and looseness of the expansion joints, which become weak points for roof leakage; and when the asphalt paste is constructed, it is very easy to cause roof pollution. Summary of the invention

[0030] Before introducing the construction method, a brief introduction is first given to the concrete body in this embodiment. The concrete body may include, from bottom to top, a structural layer 1, a leveling layer 2, a waterproof layer 3, an insulating layer 4 and an isolation layer 5. The protective layer 6 is constructed on the isolation layer 5. The isolation layer 5 must be laid flat without wrinkles, overlapped in accordance with specifications and without damage.

[0031] See also Figure 1 The concrete partition joint sealing construction method provided by the present invention comprises the following steps:

[0032] S1, constructing a protective layer 6 on the concrete body, and reserving partition joints 7 on the protective layer 6.

[0033] It is understandable that the above steps may further include:

[0034] S101, lay out partition plates and meshes on the concrete body.

[0035] It can be understood that the mesh is laid first. The mesh can be a steel mesh. The steel mesh can be laid flat on the isolation layer, the overlap meets the specifications, and it is disconnected at the partition joint 7. Then the partition board is laid. The partition board can be made of wooden strips or foam strips. The spacing between the partition boards can be set to be greater than 6 meters. The wooden strips or foam strips are selected or cut according to the thickness of the protective layer. After being laid flat on the isolation layer, the two sides are sealed and fixed firmly with cement mortar.

[0036] S102, pouring fine stone concrete on the concrete body and the mesh to form a protective layer 6.

[0037] It can be understood that after the isolation layer 5, the partition plates and the steel mesh are laid and accepted, the fine stone concrete is poured to ensure that each partition joint 7 is continuously cast and formed, and the surface is smoothed and polished at least 3 times for later maintenance.

[0038] S103, after the protective layer 6 has completed initial setting, the partition plates are removed to form partition seams 7.

[0039] It can be known that after the fine stone concrete protective layer is poured and people can stand, the partition joint plate is cleaned, the concrete on the top of the partition plate is cleaned, the foam strips and wooden strips are taken out, and the two sides of the partition joint 7 are straightened.

[0040] S2, preparing plastic granule sealing material 8.

[0041] It is understandable that the above steps may further include:

[0042] S201, obtain plastic particles and special glue in a weight ratio of 1:0.5.

[0043] It can be known that the plastic particles can be EPDM plastic particles, and the special glue can be plastic track glue.

[0044] S202, mixing and stirring the plastic particles and the special glue to form a plastic particle sealing material 8.

[0045] It is understandable that to ensure uniform mixing, the EPDM plastic particles are evenly distributed and placed in a 30L mixing bucket with a spout. Mix and use as you go and use it up in 30 minutes.

[0046] S3, compactly press the plastic particle sealing material 8 into the partitioned seam 7.

[0047] It is understandable that the above steps may further include:

[0048] S301, pouring the plastic granule sealing material 8 into the partition joint 7;

[0049] S302, applying pressure by means of a trowel;

[0050] S303, finally, the plastic granule sealant is squeezed and compacted into the partition joint 7 by a grouting tool.

[0051] It can be understood that the plastic particle sealing material in the final partition joint 7 is two millimeters lower than the protective layer on both sides of the partition joint 7. After acceptance, the subsequent construction can be carried out only after there is no adhesion when stepped on and no particles fall when touched.

[0052] From the above description, it can be known that the concrete partition joint sealing construction method provided by the present invention is resistant to ozone, heat, acid and alkali, water vapor, corrosion, aging, and elastic. When used in the partition joint 7, it can have good contact with the concrete, will not expand or contract with temperature changes, has beautiful molding, is easy to construct, and is not easy to pollute the construction area.
