The fireproof heat-insulation steel plate protection wall has the advantages that the reinforcing effect and the reinforcing effect are achieved, the high-strength protection effect is achieved, and the fireproof heat-insulation effect is achieved. And simple to operate is swift, and after the steel sheet wall module was in workshop production equipment in advance, the on-the-spot column mouting of carrying on, then insert the steel sheet wall module between the adjacent stand, carry on spacingly through the draw-in groove of stand can, simple to operate is swift, efficient to intensity is also good, only need with stand and the ground of building, top surface and the wall of building fixed firm can.
In this embodiment, the flame retardant coating is fire retardant coating, directly with fire retardant coating on the surface of interior steel sheet, outer steel sheet and reinforcing bar net, through the setting of flame retardant coating, flame retardant coating self incombustibility and low heat conductivility form fire-resistant thermal-insulated protective layer, improve fire endurance, can delay the flame temperature to the protected substrate transmission, namely delay the flame temperature and transmit towards interior steel sheet direction. Further, through pack the fire prevention insulating layer in first interval, further play fire prevention, thermal-insulated effect, after outer steel sheet outside receives the conflagration, at first the flame retardant coating just plays certain fire prevention thermal-insulated effect, and simultaneously, the setting of fire prevention insulating layer further improves the thermal-insulated effect of fire prevention. And, outer steel sheet is connected through connecting piece and reinforcing bar net, can enough make the reinforcing bar net and possess the interval between the outer steel sheet like this, can realize the packing of fire prevention insulating layer, simultaneously, the steel sheet outside receives the conflagration etc. outside, when heating outer steel sheet, because outer steel sheet only connects through connecting piece and reinforcing bar net, the transmission area that also reduces outer steel sheet heat transfer to reinforcing bar net and interior steel sheet, thereby reduce the heat conduction effect as far as, guarantee thermal-insulated effect as far as. Therefore, the temperature of the outer steel plate is lower than 140 ℃ within 1-3 hours after being subjected to the high temperature of 1400 ℃, the fire resistance limit is effectively improved, and the sufficient fire fighting time is provided. And, connect outer steel sheet and reinforcing bar net through the connecting piece, can also guarantee both joint strength.
Referring to fig. 1 to 4, the connecting pieces are metal connecting blocks, at least two groups of connecting pieces are annularly and uniformly distributed at the outer edge of the inner side surface of the outer steel plate, one side of each connecting piece is connected with the reinforcing mesh in a welded manner, and the other side of each connecting piece is connected with the outer steel plate in a welded manner.
In this embodiment, the outer steel plates and the reinforcing mesh are welded and fixed by the metal connecting blocks, in this embodiment, the four connecting pieces are respectively located at four corners of the outer steel plates or located in the middle of the peripheral outer edge of the outer steel plates, so that the connection strength between the outer steel plates and the reinforcing mesh can be ensured, the heat transfer area can be reduced, and the fireproof and heat insulation effects can be ensured. In this embodiment, four sets of connectors are provided at the four corners of the outer steel plate.
Wherein, the fire prevention insulating layer is aerogel felt layer. Adopt aerogel felt material as fire prevention insulating layer, it is effectual to prevent fires heat-proof, low cost moreover.
The thickness of the fireproof heat insulation layer is larger than 25 mm, and the thickness of the fireproof layer is larger than 2 mm. At optimum cost, the fire endurance is increased.
Referring to fig. 1 to 4, two ends of the inner steel plate are respectively provided with bending pieces 9 bending outward, two ends of the inner steel plate are respectively connected with the inner side edge of the reinforcing mesh through the bending pieces in a welding manner, and a second distance is arranged between the inner steel plate and the reinforcing mesh.
In this embodiment, under the steel plate wall module installation state, the left side and the right side of piece department of bending at the inner steel plate do not influence piling up of steel plate wall. In this embodiment, the setting of the piece of bending for be connected interior steel sheet and reinforcing bar net, both guarantee a joint strength, simultaneously, still reduce the area of contact of interior steel sheet and reinforcing bar net, reduce the area of heat transfer, improve the thermal-insulated effect of fire prevention of steel plate wall module as far as.
Referring to fig. 1 to 4, the bending piece is an L-shaped bending plate, the L-shaped bending plate includes a connecting plate 10 and a mounting plate 11, the mounting plate is disposed at the outer end of the inner steel plate, the mounting plate and the inner steel plate are connected to each other at two ends of the connecting plate, and the outer side of the mounting plate is welded to the outer edge of the inner side of the reinforcing mesh. The setting of L type board of bending can be used for being connected with the steel sheet wall promptly, and the area of contact of steel sheet and reinforcing bar net in the reduction guarantees intensity, simultaneously, can also be built on stilts between interior steel sheet and the reinforcing bar net, forms the second interval, and the area of contact between steel sheet and the reinforcing bar net in the reduction reduces the heat transfer effect to improve the thermal-insulated effect of fire prevention.
Referring to fig. 1 and 2, a bending plate 12 is respectively arranged on each of two sides of the inner steel plate beside the bending piece, the side wall of the bending plate is connected with the outer wall of the reinforcing mesh in a welding manner, and the side wall of the bending plate is connected with the outer wall of the connecting piece beside the bending piece in a welding manner.
Through the setting of the board of bending, interior steel sheet both can be connected through a piece of bending and reinforcing bar net, simultaneously, can also connect through the board of bending and connecting piece, can utilize the connecting piece and bend the board like this and will interior steel sheet and outer steel sheet and connect, increase the bulk strength of steel sheet protective wall, even say that the junction between interior steel sheet, outer steel sheet and the reinforcing bar net probably appears the part pine and takes off, does not influence the bulk strength of steel sheet wall module yet.
Simultaneously, when the steel plate wall module was installed between adjacent stand, the piece department of bending can block into the draw-in groove of stand in, through the inside of draw-in groove restriction steel plate wall module, prevented that it from exposing, the board of bending then up, down blocks the inside of steel plate wall module, prevents that it from exposing, guarantees its intensity, also prevents that inside fretwork from spilling, plays a safeguard effect. And, because the steel sheet wall module is by lower supreme when piling up in proper order, the board of bending of a set of steel sheet wall module bottom in top can support on the board of bending at a set of steel sheet wall module top in below, still plays the supporting role, increases area of contact, improves a supporting effect, prevents that interior steel sheet or outer steel sheet among the steel sheet wall module of below warp.
Wherein the reinforcing steel bars in the reinforcing mesh are round reinforcing steel bars with the diameter larger than or equal to 14 millimeters; the thickness of the inner steel plate is less than that of the outer steel plate.
The thickness of the inner steel plate is 2-5 mm; the thickness of the outer steel plate is 6-10 mm.
The setting of reinforcing bar diameter and inside and outside steel sheet thickness can enough satisfy the national standard requirement, can also guarantee its protective strength.
