Seamless treatment method for cement decoration hanging plates of building external wall

Abstract

The invention provides a seamless treatment method for cement decoration hanging plates of a building external wall. The seamless treatment method includes the following steps of sealing gluing treatment of inter-plate gaps, mounting of separation blades and lining formworks, pouring of concrete post-pouring strip belts, and dismounting of the separation blades. According to the seamless treatment method for the cement decoration hanging plates of the building external wall, the inter-plate gaps, inside post-pouring seams, between every two adjacent hanging plates are filled with sealing glue, and thus system sealing is formed so as to meet the waterproof requirements of the hanging plates of the external wall; after the concrete post-pouring strip belts are arranged at the hanging plate joints, the preset spacing is formed between the concrete post-pouring strip belts and the hanging plates, the expansion-retraction effect, the seismic displacement effect, the manufacturing and construction error, the wind load displacement effect, the expansion-retraction and creep effects in concrete preparation and the like caused by the change of temperature and humidity can be met; and the outer walls of the concrete post-pouring strip belts can be arranged to be of a concave-convex structure corresponding to decorative layers of the hanging plates, thus the appearance of the joints is close to the appearance of the hanging plates, and the attractiveness of the external wall is improved.

Description

technical field [0001] The invention relates to the technical field of building exterior wall hanging panels, in particular to a seamless processing method for building exterior wall cement decorative hanging panels. Background technique [0002] Cement-like decorative hanging panels on building exterior walls, such as GRC hanging panels, GRC (Glass fiber Reinforced Cement) is a fiber-concrete composite material with alkali-resistant glass fiber as a reinforcing material and cement mortar as a matrix material. It is composed of high elastic modulus The glass fibers are embedded in the cement matrix. GRC building exterior wall decorative hanging panels are generally composed of GRC ribbed plates and back-attached steel frames, of which the ribbed plates are non-load-bearing exterior decorative components of the building, and the back-attached steel frames are metal frames with structural functions. Gravity anchors support the GRC ribbed panels and are connected to the main s...
