Description

Technical field:

[0001] The utility model relates to the field of building walls, in particular to a fireproof and heat-insulating integrated wall. Background technology:

[0002] With the development of energy-saving work, building exterior wall insulation technology has been widely used. There are many common insulation technologies, including fixing polyethylene extruded boards, polyurethane foam material filling layers, expanded polystyrene boards or glass wool and rock wool boards on the outer surface of the wall. Polyethylene extruded boards and polyurethane foam material filling layers have good insulation effects, good moisture and water resistance, and high strength, but the cost is high and the fire resistance is poor; expanded polystyrene boards have good insulation effects and low costs, but there is a problem of difficulty in surface treatment during construction, and their fire resistance is poor; glass wool and rock wool boards have the advantages of fire retardancy, but their insulation effects are average.

[0003] The above-mentioned exterior wall insulation technology fails to take into account both fire resistance and thermal insulation. If the insulation layer and the fireproof layer are fixed on the outside of the wall in sequence, and then the outermost plaster layer and the finishing layer are added, the weight and thickness of the material on the outside of the wall will be large, and it will be easy to fall off after long-term use, posing a safety risk. If prefabricated insulation and fireproof panels are used, due to area limitations, multiple panels often need to be fixed on the outside of a wall, and gaps are inevitable between each panel. Once a fire occurs, the gaps will form a channel for the fire to spread, making the fire difficult to extinguish. Utility model content:

[0004] The utility model aims to provide a fireproof and heat-insulating integrated wall body, which has heat-insulating, fireproof and anti-penetration properties, and has low construction difficulty and low cost.

[0005] The utility model is implemented by the following technical solutions:

[0006] A fireproof and heat-insulating integrated wall, which comprises a wall, a fireproof and heat-insulating layer, and a plastering layer in order from the inside to the outside; the fireproof and heat-insulating layer comprises a nylon frame and a fireproof and heat-insulating viscous filler filled in the nylon frame, the fireproof and heat-insulating viscous filler is filled in the nylon frame, and can be firmly fixed to the outside of the wall by virtue of its own adhesion with the wall and the supporting effect of the nylon frame, thereby avoiding the problem of easy falling off of the heat-insulating and fire-proof prefabricated board; the nylon frame comprises a first frame, the first frame comprises a plurality of staggered longitudinal rods and a plurality of A crossbar; a fixing rod is provided at the intersection of the longitudinal rod and the crossbar, and one end of the fixing rod is in contact with the wall; the longitudinal rod, the crossbar, and the fixing rod are integrally formed; a through hole is provided at the intersection of the longitudinal rod and the crossbar, the fixing rod is hollow inside to form a through diameter, the through hole is connected with the through diameter to form a reserved hole, and the plastic expansion anchor bolt passes through the reserved hole to fix the nylon frame on the wall, and the plastic expansion bolt increases the integrity of the nylon frame, the fireproof and heat-insulating viscous filler and the wall. The thickness of the nylon frame can be determined according to the requirements of the local construction site, and the nylon frame can be prefabricated and trimmed according to the size requirements. After the nylon frame is fixed to the wall by the plastic expansion bolt, the fireproof and heat-insulating viscous filler can be filled in the nylon frame, which solves the construction problems such as the need for multiple spraying of heat-insulating and fire-proof materials and the difficulty in operating corners, and the construction method is simple and convenient. The nylon frame itself has heat insulation, which will not affect the heat-insulating effect of the fireproof and heat-insulating layer, and the price is low, which can save costs. The fireproof and heat-insulating viscous filler has good fireproof performance and can reduce the fire risk of the wall. The nylon frame, the fireproof and heat-insulating viscous filler and the wall are integrated without forming gaps inside. Even if a fire occurs, the fire can be prevented from spreading.

[0007] Preferably, the second frame includes vertical fine grids and horizontal fine grids; the vertical fine grids are fixedly connected between two upper and lower adjacent fixing rods, one side of the vertical fine grids is fixedly connected to the longitudinal rods, and the other side is connected to the wall; the horizontal fine grids are fixedly connected between two left and right adjacent fixing rods, one side of the horizontal fine grids is fixedly connected to the crossbars, and the other side is connected to the wall. The setting of the second frame is conducive to the fireproof and heat-insulating viscous filler being fixedly bonded in the nylon frame.

[0008] Preferably, the mesh diameters of the vertical fine mesh and the horizontal fine mesh are 1-2 cm.

[0009] Preferably, the plastering layer includes at least one of a cement anti-cracking mortar layer, a waterproof coating layer, and a decorative layer.
