Fireproof thermal insulation board for interior wall with heat not liable to lose

Abstract

The invention relates to the field of buildings, in particular to a fireproof thermal insulation board for an interior wall with heat not liable to lose. The fireproof thermal insulation board comprises a board body, wherein the board body comprises a thermal insulation layer, a fireproof layer and a decorative surface layer from outside to inside in sequence, wherein one surface, close to a wallbody, of the thermal insulation layer is provided with a rectangular pit which penetrates through the thermal insulation board; a soundproof layer and a heat insulation layer are sequentially arrangedon the thermal insulation board on the top of the pit; the heat insulation layer, the soundproof layer and the thermal insulation board are prefabricated and fixedly mounted through rivets; reinforcing ribs are arranged in the thermal insulation boards at the two sides of the pit, and the outer side surfaces of the fireproof thermal insulation boards are covered by panels; a connector is prefabricated and mounted on the interior wall; the connector is L-shaped, and comprises a bottom plate and side plates; the bottom plate is riveted with the wall body through a rivet; an elastic cushion is cushioned between the bottom plate and the wall body; the bottom plate is positioned on bulged parts on the side surfaces of the pits of the thermal insulation boards; the side plates abut against theouter side surfaces of the thermal insulation boards; and the side plates are fixed with the thermal insulation boards through rivets. The device provided by the invention is good in thermal-insulation soundproof effect, is easy to mount, and is stable in structure.

Description

technical field [0001] The invention relates to the field of construction, in particular to a fire-proof and heat-insulating board for inner walls that is not easy to dissipate heat. Background technique [0002] The insulation board is usually EPS board (also known as benzene board), which is the abbreviation of expandable polystyrene board. It is a polystyrene foam plastic sheet with a closed-cell structure obtained by heating and pre-foaming expandable polystyrene beads and then heating them in a mold. It is widely used in construction, heat preservation, packaging, refrigeration, daily necessities, industrial casting and other fields. It is used in the interior walls of buildings, especially kitchens or balconies, to prevent the loss of indoor heat. The interior wall insulation of the prior art is generally After laying the insulation board on the leveling layer, and then laying a layer of glass fiber mesh, and then laying a layer of leveling layer and pasting the decor...
