Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation boards, in particular to a composite thermal insulation board system. Background Art

[0002] In the prior art, composite insulation panels are installed using adhesive mortar and insulation nails. Because the surface only requires a simple paint treatment and does not bear weight, the bonding strength provided by this system is sufficient. However, a risk in the installation of composite insulation panels lies in the tendency for cracking at the joints between the panels, which can lead to cracking in the paint and putty layers. During the installation of composite insulation panels, cement-based adhesives can be used. However, to save costs, workers often use the same cement adhesive for the joints, which creates the risk of shrinkage cracking. This is because gypsum board deforms due to factors such as humidity, ambient temperature, and building settlement. This, combined with the inconsistent shrinkage rate of the materials at the joints, leads to cracking. Shrinkage cracking is a persistent problem. Once cracking occurs on the painted surface, it cannot be repaired with surface repairs. The only solution is to remove the surface putty layer, re-pattern the gap with anti-cracking mortar, and then apply putty and paint. This significantly increases the amount of rework required for the final renovation and increases various costs. Summary of the Invention

[0021] Further, if Figure 1 As shown, in this embodiment, it also includes: a joint tape 4, which is pasted on the dry caulking plaster 2 with environmentally friendly white glue, uses virgin wood pulp, and has a roughened surface. It has strong bonding strength and strong shrinkage resistance, which reduces cracking at the later joints.

[0022] Further, if Figure 1 As shown, in this embodiment, fixing holes are opened on the board surface of the graphite EPS composite gypsum board 1, and the fixing holes are used to install insulation nails 5 for reinforcement. The insulation nails 5 are made of stainless steel.

[0023] Further, if Figure 1 As shown, in this embodiment, an insulation strip 7 is fixed between the peripheral surface of the graphite EPS composite gypsum board 1 and the external wall 6. The material of the insulation strip 7 is EVA. The insulation strip 7 fills the gap caused by the insufficient flatness of the wall 6, and uses its strong heat insulation ability to reduce the thermal bridge effect and reduce the probability of mold.

[0024] Further, if Figure 1 As shown, in this embodiment, the thickness of the insulation strip 7 is the same as the thickness of the graphite EPS composite gypsum board 1, which is more beautiful and consistent.

[0025] Further, if Figure 1 As shown, in this embodiment, the graphite EPS composite gypsum board 1 is bonded to the base wall surface of the building exterior wall by bonding gypsum.

[0026] Working principle: Before the construction of the graphite EPS composite gypsum board 1, use EVA insulation strips 7 with the same thickness as the graphite EPS composite gypsum board 1 to stick on all sides of the construction surface; use bonding plaster and the dot frame method to bond the bottom of the graphite EPS composite gypsum board 1 to the wall base surface of the building's exterior wall, and the bonding area is not less than 40% of the entire board area; at the joints between the two boards, use caulking plaster 2 to fill the gap first, and then press the grid tape 3 into the caulking plaster 2; you can use masking tape to stick on both sides of the grid tape 3, and apply caulking plaster 2 to the surface for the second time. After the scraping is completed, tear off the masking tape to make the joints neat and beautiful; after waiting for the caulking plaster 2 to dry, use environmentally friendly white glue to accurately stick the joint tape 4 between the two boards; after the bonding plaster is dry, drill holes in the board surface and install stainless steel insulation nails 5.
