Problems solved by technology
There are many disadvantages in this traditional large-span roof insulation board in engineering applications: (1) The C-shaped channel steel frame runs through the entire roof insulation board. Since steel is a good heat-conducting material, there are obvious cold and heat bridge effects around the roof insulation board; ( 2) The bonding strength between the foamed concrete insulation layer and the fiber-reinforced cement protective layer on the upper and lower surfaces is low, and it is easy to peel off and delaminate; (3) The foamed concrete insulation layer is an inorganic porous material with low strength and poor toughness. The cracking problem that is easy to occur in the process is difficult to solve
These factors limit the application of traditional large-span roof insulation panels

The invention relates to a 3D fabric and foam concrete composite roof insulation board and a manufacturing method thereof. The insulation board comprises an insulation board body and angle steel, wherein the insulation board comprises two prefabricated protection layer boards, two bonding layers and a 3D fabric layer; the 3D fabric layer is connected between the two prefabricated protection layer boards through the bonding layers, the 3D fabric layer is provided with a cavity, and foam concrete fills the cavity of the 3D fabric layer; two groups of angle steel are arranged, one group of angle steel is fixedly installed on the edges of the periphery of one prefabricated protection layer board through anchor bolts, and the other group of angle steel is fixedly installed on the edges of the periphery of the other prefabricated protection layer board through anchor bolts, wherein a predetermined distance is reserved between the two groups of angle steel; the end surface of the insulation board body is flush with the end surface of the angle steel. The composite roof insulation board provided by the invention effectively avoids a cold bridge effect between upper and lower surface layers of the insulation board and improves the insulation effect.
Description
technical field [0001] The invention relates to a roof insulation board and a preparation method thereof, in particular to a 3D fabric foam concrete composite roof insulation board and a preparation method thereof. Background technique [0002] With the gradual improvement of building energy saving and building fire protection requirements, the amount of large-span prefabricated foam concrete composite insulation boards used for industrial and civil building roofs is increasing. The traditional large-span roof insulation board mostly uses C-shaped channel steel as the frame, and the frame is equipped with steel wire mesh and filled with foam concrete, and the upper and lower surfaces are coated with fiber-reinforced cement protective layer. There are many disadvantages of this traditional large-span roof insulation board in engineering applications: (1) The C-shaped channel steel frame runs through the entire roof insulation board. Since steel is a good thermal conductivity ...
