Embodiment approach

[0033] Such as Figure 1-8 After the internal adhesive material shown is cured, fiber-reinforced composite materials (Fibre-Reinforced Polymers, referred to as FRP, including carbon fiber CarbonFibre-Reinforced Polymers, referred to as CFRP, aramid fiber AramidFibre-Reinforced Polymers, referred to as AFRP and glass fiber Glass Fiber-Reinforced Polymers, GFRP for short) for surface suture --- outer curium.

[0034] (1) Surface-bonded fiber-reinforced composites (FRP) ( image 3 , Figure 4 , Figure 7 , Figure 8 )

[0035] Surface-adhesive FRP is suitable for the reinforcement of concrete and masonry, mainly including base treatment, priming, leveling, pasting and other processes:

[0036] Grass-roots treatment: Pop up the smoothing control line at the pasting position. The length direction of the smoothing control range should be increased by 50mm from each side of the pasted range, and the width direction should be increased by 30mm from each side of the pasted range. ...

Abstract

The present invention provides a reinforcing method for treating the concrete and masonry structural crack, according to the concrete condition of the crack, a self-pressure crack processor or air compressor is adopted for assorting the pressure generated by equipments of a slurry storing pot and the like, the corresponding grouting material is pressed into the existing crack, after the hardening of the grouting agent the concrete or masonry at the two sides of the crack can be adhered from the inner side namely inner adhering; the high-technique materials of FRP board, sheet material, rod material and the like or the ordinary materials of reinforcing steel bar, steel plate and the like is selected for adhering across the crack or a groove is cut for anchoring, the concrete at the two sides of the crack is connected from the outside namely exterior cramping. The adopting of the method can thoroughly settle the problem of the building structural crack.

Description

Technical field [0001] The invention relates to the technical field of buildings, in particular to a method for repairing cracks in building structures. Background technique [0002] In all kinds of construction projects, concrete and masonry materials are multi-component, multi-phase, heterogeneous composite materials, and at the same time, they are materials with high elastic modulus and low tensile strength. Due to environmental temperature, humidity, load and other factors, as long as a little shrinkage occurs, the tensile stress generated will often be greater than the tensile strength of concrete and masonry materials, resulting in cracks in concrete and masonry. Cracks in the building not only affect the perception and normal use, but also reduce the bearing capacity, integrity and durability of the structure, and seriously cause the building to be damaged or even collapsed. On the other hand, with the improvement of people's living standards, the requirements for bu...
