Quality Inspection Of GRC Component After Construction

Source:

First: GRC component in the construction is completed, the outdoor area in accordance with the number of buildings to check.

Second: GRC component strength to meet the design requirements, the surface should be no cracks. Check the GRC component factory certificate, product quality certificate, check the strength of cement mortar, and check the surface of GRC component.

Third: the strength of the mortar to meet the design and related specifications, GRC component bonded firmly, no cracks, inspection method is to check the mortar strength of the report. Waterproof construction and practices to meet the design and related regulatory requirements, the inspection method is to check the quality of the product.

Fourth: GRC component installation method and installation quality to meet the design requirements, the installation time to be firmly not loose, check the method is gently shaking by hand.

GRC component installation steps are as follows:

GRC is a kind of fiber cement composite material with alkali-resistant glass fiber as reinforcing material and cement mortar as matrix material. GRC is a kind of material which is designed by modeling, texture, texture and color expression designer. So, how does the GRC widget make the installation?

First, the GRC component corner, the edge should be set not less than Ø4 long continuous continuous scoring steel wire; Geometric size greater than 400 mm GRC component should be equipped with steel mesh, the steel bar diameter of not less than Ø6, spacing of not more than 400 mm; GRC component geometric size should not exceed 1000mm, when more than 1000mm, the diameter and spacing of steel structures determined by the structure.

Second, the thickness of the protective layer should not be less than 15mm; component ribs (only the geometric size of the steel parts should not be less than 6d, and add alkali glass fiber mesh, mesh cloth width 200mm.

Third, GRC component minimum wall thickness should not be less than 8 mm; the width of the top is greater than 300 mm, the minimum wall thickness should not be less than 30 mm.

Fourth, the GRC component of the reserved joints generally use reserved steel or reserved anchor plate in two ways:

(1) When the GRC component is small (the maximum size is less than 600 mm, and the weight is less than 25kg), the component reinforcement can be exposed directly, the exposed length should be greater than 10d and meet the welding requirements;

(2) When the GRC component is large (maximum geometry is greater than or equal to 600 mm, or the weight is greater than or equal to 25kg), should be reserved anchor plate, anchor plate should be used not less than Q235 steel strength, anchor plate thickness should not Is less than 0.6 times the diameter of the reinforcement of the component, the galvanized layer of the anchor plate is not less than 350g / ㎡; the distance D between the center of the bolt or the center of the bolt and the center of the bolt shall not be less than 2d or 20mm, between the perforation and the reinforcement The maximum gap should not be greater than 2 mm. Reinforcement of steel bar and anchor plate.
