Description

Leveling layer crack filling structure

Technical Field

The disclosure relates to the technical field of building construction engineering, in particular to a screed-coat crack-filling structure for resisting crack cracking.

Background

With the development of the architectural decoration and repair industry, people have higher and higher requirements on the building living and production environment. The ground surface layer of the building is usually arranged on a leveling layer, and the leveling layer is mostly made of fine stone concrete. In the process of increasing the strength of concrete, shrinkage cracks are usually generated due to the performance of concrete materials, no measures are taken for the existing cracks, and a surface layer material can crack due to the development of cracks of a leveling layer, so that the appearance and the use function are influenced.

Disclosure of Invention

The utility model provides a screed-coat crack filling structure can make the crack on the screed-coat resist the contractile force of concrete, can prevent that the crack from further ftractureing. The specific technical scheme is as follows:

the disclosed leveling layer joint repairing structure comprises a leveling layer formed by tiling fine stone concrete, a crack positioned on the leveling layer and a joint cutting intersected with the crack, wherein a corrugated steel plate is fixed inside the joint cutting; the inside and the joint-cutting of this crack all are filled with epoxy interface and glue, and the surface that this epoxy interface was glued is parallel and level with the surface of screed-coat.

The utility model discloses a screed-coat crack filling structure, through be equipped with the joint-cutting crossing with the crack in crack production department, be fixed with corrugated steel sheet in this joint-cutting inside, inside and the joint-cutting inside packing of crack have epoxy interface glue for the crack is mended neat and makes the crack can resist the contractility of concrete, can prevent that the crack from further ftractureing, guarantees the level and smooth on screed-coat surface.

Optionally, the screed has a thickness of 50-60 mm.

Optionally, the intersection of the slit and the slit is orthogonal.

Optionally, the depth of the slit and the depth of the kerf are both 15-20 mm.

Optionally, the corrugated steel sheet has a thickness of 0.2mm and a width of 10 mm.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The terms "first" or "second", etc. are used merely to distinguish the same type of component or device, and do not represent limitations.

As shown in fig. 1, the screed layer gap repairing structure of the present disclosure includes a screed layer 1 formed by laying fine stone concrete, a crack 2 located on the screed layer 1, and a cutting seam 3 intersecting with the crack 2, wherein a corrugated steel plate 4 is fixed inside the cutting seam 3; the inside of the crack 2 and the inside of the joint-cutting 3 are both filled with epoxy resin interface glue 5, and the surface of the epoxy resin interface glue 5 is flush with the surface of the leveling layer 1.

Wherein, the thickness of the leveling layer 1 is 50-60 mm; the intersection of the slit 2 and the cutting seam 3 is orthogonal; the depths of the crack 2 and the cutting seam 3 are both 15-20 mm; the corrugated steel plate 4 has a thickness of 0.2mm and a width of 10 mm.

The corrugated steel plate 4 can be fixed on two sides of the cutting seam 3 through screws, and when concrete shrinks, the corrugated steel plate 4 can pull two sides of the cutting seam 3 to prevent the width of the crack 2 from expanding.

Wherein, the same crack 2 can be crossed with at least two slits 3, and the interval between the at least two slits 3 can be set to be 10 cm; the corrugated steel plates 4 in the at least two slits 3 can further resist the contraction force of concrete, consolidate the crack 2 and prevent the crack 2 from expanding.

The manufacturing process of the leveling layer gap filling structure comprises the following steps: cleaning irregular cracks on the leveling layer, wherein the cleaning depth is determined according to the crack development condition, and the general depth is 15 mm; cutting a seam every 10cm in the direction perpendicular to the seam by using a small concrete cutting machine after cleaning the seam, wherein the depth of the cut seam is 15mm, installing a corrugated steel plate with the thickness of 0.2mm and the width of 10mm in the cut seam after cleaning the cut seam, and painting and pouring the seam on the seam and the cut seam by using epoxy resin interface adhesive; and after the strength of the epoxy resin interface adhesive is increased to 100%, polishing and repairing are carried out by adopting a polisher, so that the surface of the repaired epoxy resin interface adhesive is flush with the surface of the leveling layer, and the repaired epoxy resin interface adhesive is polished to be smooth and attractive, and the epoxy resin interface adhesive has the paving construction conditions of surface layer materials such as epoxy self-leveling or rubber floors.

It should be understood that the fixing in the embodiments of the present disclosure may refer to welding, bolting, or screwing. The present disclosure is not limited to the precise structures that have been described above and shown in the drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
