Abstract

The invention discloses an anchor-free EPS decorative component system. A groove is formed in the bottom surface of an EPS decorative component polystyrene board base body, during assembling, reinforcing anchors are not required, the working period is shortened, the cost is reduced, furthermore, a cold bridge formed by holes caused by nailing is avoided, and meanwhile, the quality problem caused by rusting of the anchors is avoided; a groove and a protrusion are arranged at the two ends of an EPS decorative component, firm attachment is implemented during lap joint, and cracks of a finish coatare avoided. Special binding mortar for the EPS decorative component has the characteristics of good initial mobility, high early strength, good permeability and high size stability, development of later strength is not affected while high early strength can be ensured, and by addition of a water retaining agent, the circumstance that the initial mobility of the mortar is reduced due to increasing of stickiness while full water-retaining property can be ensured; by addition of a surfactant, the surface tension of mortar is reduced, and permeability is enhanced; and by addition of a thixotropic lubricant, the mortar has a good application property and good sagging resistance.

Description

technical field [0001] The invention relates to the field of EPS decorative components, in particular to an anchorless EPS decorative component system. Background technique [0002] When assembling traditional EPS decorative components, in addition to bonding with bonding mortar, in order to make up for the lack of mortar bonding force, several anchors need to be reinforced according to the component quality, size and building height. Anchor nails are added to the component to fix it, and holes are formed on the surface of the component, forming a cold bridge and reducing the thermal insulation effect. Moreover, anchors are easily rusted by rainwater and moisture erosion, which reduces the service life of EPS decorative components. Contents of the invention [0003] In view of this, the object of the present invention is to provide an EPS decorative component system without anchors, which does not need to reinforce the anchors during assembly, which not only shortens the ...
