Example 1
Embodiment 1 is one of the structures of the present invention, including: a heat-insulating prefabricated slab is fixedly arranged on the base wall 1; a heat-insulation bridge connecting piece is fixedly arranged on the other plate surface of the heat-insulation precast slab, a heat-insulation bridge anchor bolt 2 is arranged on the heat-insulation bridge connecting piece in a penetrating manner, and the connecting end of the heat-insulation bridge anchor bolt 2 penetrates through the heat-insulation precast slab to be fixedly connected with the base layer wall body 1; an external decorative overlapping plate 8 is also fixedly arranged on the heat-insulating bridge connecting piece.
In this example 1, as shown in fig. 1 and 2, the insulating prefabricated panel comprises: the polymeric polystyrene board 4 is fixedly arranged with the base layer wall 1, and the vacuum insulation board 6 is fixedly arranged on the other board surface of the polymeric polystyrene board 4. Wherein, the special bonding mortar 5 for heat preservation is respectively coated between the base wall 1 and the polymerized polystyrene board 4 and between the polymerized polystyrene board 4 and the vacuum heat insulation board 6. The design ensures the integral fixation of the heat-insulating precast slab, and the heat-insulating precast slab is firmly fixed on the base wall 1 by utilizing the sticking and hanging double-fixation mode of the heat-insulating bridge connecting piece and the special bonding mortar 5 for heat insulation.
Wherein, in order to pursue the building of ultralow energy consumption and reach: the heat preservation effect that the thermal resistance value exceeds 5.0m2 k/w, the thickness of the polymerized polyphenyl board 4 is set as 100 mm; the heat conductivity coefficient is 0.04W/(m.K), and the thermal resistance value is 2.5m 2.K/W;
the thickness of the vacuum insulation panel 6 is set to be 20 mm; the thermal conductivity coefficient is 0.04W/(m.K), and the thermal resistance value is 3.6m2. K/W.
Example 2
In example 2, as shown in fig. 3, the heat cutoff bridge connector includes: a plurality of T-shaped hard polyurethane heat insulation strips 3 are arranged on the other side of the plate surface of the vacuum heat insulation plate 6 at intervals, T-shaped bulges of each T-shaped hard polyurethane heat insulation strip 3 are embedded on the vacuum heat insulation plate 6 respectively, a heat-breaking bridge anchor bolt 2 is arranged on the T-shaped hard polyurethane heat insulation strips 3 in a penetrating mode, and the connecting end of the heat-breaking bridge anchor bolt 2 penetrates through the vacuum heat insulation plate 6 and the polymerized polyphenyl plate 4 to be fixedly connected with the base layer wall body 1.
Among them, the material thermal conductivity coefficient of the T-shaped hard polyurethane heat insulation strip 3 is lower than 0.024W/(m.K), and the T-shaped hard polyurethane heat insulation strip is an ideal heat insulation material. The design not only plays a role of fixing the heat-insulating precast slabs (the vacuum heat-insulating slabs 6 and the polymerized polystyrene slabs 4) on the basic wall, but also reduces the generation of a heat bridge structure in the traditional installation structure through the matched installation structure of the T-shaped hard polyurethane heat-insulating strips 3 and the heat-breaking bridge anchor bolts 2, and avoids adverse effects such as condensation and mildewing of the building wall or reduction of the heat-insulating effect caused by the heat bridge structure.
