Problems solved by technology

[0002] At present, the existing treatment methods for concrete cracks include surface sealing method and pressure injection method, which are mainly to seal concrete cracks and heal and fill them. The requirements are high, and the interface cleaning and strength requirements are also high, especially for serpentine concrete cracks. Due to the complicated direction of the cracks, the grinding of the cracks is time-consuming and laborious, and after the cracks are filled, at the crack interface It is relatively weak and may become two cracks, and the crack problem cannot be completely resolved

Embodiment 1

[0026] Example 1: as attached Figure 1-2 The invention is a serpentine concrete crack treatment equipment, including a double-layer steel mesh body, the double-layer steel mesh body can be bent according to the shape of the serpentine concrete crack, and the double-layer steel mesh body can be folded into a serpentine concrete crack The main body of the double-layer steel mesh includes an upper steel mesh 1 and a lower steel mesh 2. Preferably, the pores of the upper steel mesh 1 and the lower steel mesh 2 are 2-3 mm. The upper wire mesh 1 and the lower wire mesh 2 are fixedly connected, and the upper wire mesh 1 and the lower wire mesh 2 form a closed cavity, and the closed cavity is filled with several layers of glass ribbons 3 soaked in epoxy resin, preferably Yes, the number of layers of the glass ribbon 3 is 3-6 layers.

[0027] Further, the cross section of the double-layer steel mesh body is in a semi-circular arc shape, so that the double-layer steel mesh body has a ...

Embodiment 2

[0030] Embodiment 2: the present invention is a kind of using method of serpentine concrete crack treatment equipment, including steps:

[0031] S1. Carve out both sides of the concrete crack to form crack grooves, and grind the crack grooves;

[0032] 2-5cm on both sides of the concrete crack can be chiseled, the depth is 1.5-2cm, the specific size is determined according to the actual situation, and the width of the concrete crack groove is smaller than the width of the main body of the double-layer steel mesh.

[0033] S2. Clean up the crack groove, and clear the debris, dust, etc. in the crack groove;

[0034] S3. According to the shape of the crack groove, the main body of the double-layer steel mesh is bent into the shape of the crack groove;

[0035] S4, buckle the main body of the semi-circular double-layer steel mesh in the crack groove, and fix the main body of the double-layer steel mesh in the crack groove through steel nails;

[0036] After the main body of the ...

Abstract

The invention discloses snakelike concrete crack treatment equipment and a using method, and mainly relates to the technical field of buildings. Comprising a double-layer steel wire mesh body, the double-layer steel wire mesh body comprises an upper steel wire mesh and a lower steel wire mesh, the upper steel wire mesh is fixedly connected with the lower steel wire mesh, a closed cavity is defined by the upper steel wire mesh and the lower steel wire mesh, and the closed cavity is filled with a plurality of layers of glass tapes soaked with epoxy resin; the crack cleaning requirement is low, the bearing capacity of the component can be effectively recovered or improved, crack expansion is restrained, and the crack problem can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a serpentine concrete crack treatment equipment and a using method. Background technique [0002] At present, the existing treatment methods for concrete cracks include surface sealing method and pressure glue injection method, mainly to seal the concrete cracks, heal and fill them, and have no substantial restraint effect on the control and expansion of the cracks, and clean up the cracks. The requirements are higher, and the interface cleaning and strength requirements are also higher, especially for serpentine concrete cracks, due to the complex direction of the cracks, the grinding of the cracks is time-consuming and laborious, and after the cracks are filled, at the crack interface It is relatively weak and may become two cracks, and the crack problem cannot be completely solved. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to solve the p...
