As an embodiment of the invention, the flame retardant ring 9 is prepared by mixing expanded graphite, sodium bicarbonate particles and pesticide raw materials, and the sodium bicarbonate particles are subjected to stearic acid modification coating treatment; when the fire extinguishing device works, the flame-retardant ring 9 expands when meeting high temperature, sodium bicarbonate is heated in the flame-retardant ring 9, when a fire disaster happens, the sodium bicarbonate is decomposed to generate carbon dioxide gas and water, the carbon dioxide gas isolates oxygen, the fire behavior is convenient to extinguish, and meanwhile, the water absorbs heat quantity to become water vapor, so that the effects of cooling and diluting oxygen are achieved, and the fireproof performance of the reinforced pipe 6 and the wall body 1 is effectively improved; after the sodium bicarbonate particles are subjected to stearic acid modification and coating treatment, the initial decomposition temperature of the sodium bicarbonate can be increased to more than 100 ℃, and the sodium bicarbonate in the flame-retardant ring 9 is prevented from being decomposed due to heat generated during daily use of the wire to influence the flame-retardant effect of the flame-retardant ring 9; meanwhile, related raw materials of the insecticide are added into the flame-retardant ring 9, so that the electric wire can be prevented from being bitten and damaged by insects and ants in the reinforcing pipe 6, and the service life of the electric wire is prolonged.
The specific working process of the invention is as follows:
when the wall body 1 is in work, a plurality of groups of hollow pipes 2 are arranged along the length direction of the wall body 1, limiting reinforcing steel bars 4 are laid into a grid structure through holes 5 in corresponding side plates 3, the placed limiting reinforcing steel bars 4 are bundled through steel wires, the limiting reinforcing steel bars 4 are integrated, then a wall body 1 formwork is erected, the end parts of the limiting reinforcing steel bars 4 are fixed with the formwork, concrete is poured into the formwork, and the concrete PVC hollow pipe 2 wallboard is obtained after maintenance and formwork removal; the side plates 3 are arranged on the periphery of the hollow pipe 2, when the limiting steel bars 4 penetrate through the through holes 5 in the side plates 3, the limiting steel bars 4 limit the side plates 3 and the hollow pipe 2 from multiple directions around, so that the position of the hollow pipe 2 is prevented from shifting, the limiting steel bars 4 penetrate through the through holes 5 in the side plates 3, so that the side plates 3, the hollow pipe 2 and the limiting steel bars 4 are connected into a whole, the gravity of the whole of the side plates 3, the hollow pipe 2 and the limiting steel bars 4 is increased, the number of connecting points is large, the connecting strength is improved, and the limiting steel bars 4 and the side plates 3 are mutually limited, so that the anti-floating capacity of the side plates 3, the hollow pipe 2 and the limiting steel bars 4 is effectively improved, the position shifting of the local hollow pipe 2 and the limiting steel bars 4 is prevented, the quality of a built wall body 1 is influenced, and safety accidents occur; on the other hand, the side plates 3 are perforated in advance, when in site construction, the limiting reinforcing steel bars 4 penetrate through the through holes 5 on the corresponding side plates 3, so that the laying of the limiting reinforcing steel bars 4 can be completed quickly, the site construction efficiency is improved, the situation that the laying of the limiting reinforcing steel bars 4 can be completed only by measuring and positioning the positions of the limiting reinforcing steel bars 4 when the concrete wallboard is poured in the prior art is avoided, and the construction period is prolonged; after the limiting steel bars 4 are laid, the limiting steel bars 4, the side plates 3 and the hollow pipes 2 are connected with one another, the structural strength of the wall body 1 is increased, and when the wall body 1 is subjected to a large acting force, the limiting steel bars 4, the side plates 3 and the hollow pipes 2 transmit dispersed acting force with one another, so that the supporting strength and the compression resistance of the wall body 1 are effectively improved, and the wall body 1 is prevented from cracking;
meanwhile, the reinforcing pipe 6 and the supporting plate 7 are arranged in the hollow pipe 2 to improve the bearing capacity of the hollow pipe 2, so that the structural strength and the pressure resistance of the interior of the wall body 1 are improved, and the conditions that the wall body 1 is deformed and broken due to the thin wall and low supporting strength of the hollow pipe 2 and the local collapse, crack and the like of the wall body 1 are caused when the wall body 1 is subjected to a large acting force are prevented, so that the service life of the wall body 1 is prolonged, the maintenance period and the cost are reduced, and accidents are avoided; in addition, the hollow pipe 2 can be prevented from being sunken, cracked and damaged due to the fact that concrete impacts the PVC hollow pipe 2 in the pouring process, and the forming quality of the wallboard is guaranteed; sound-absorbing cotton 8 is arranged between the supporting plates 7 to block the transmission of noise, so that the overall sound insulation effect of the wall body 1 is enhanced, and the living comfort of the house is improved; meanwhile, sound absorption cotton 8 is filled between the adjacent supporting plates 7, so that the space utilization rate between the hollow pipe 2 and the reinforcing pipe 6 can be improved, the structural compactness of the wall body 1 is improved, and the structural strength of the wall body 1 is enhanced; in addition, because the outer surface of the hollow pipe 2 is corrugated, the contact area between the hollow pipe 2 and the concrete wall 1 can be increased, the firmness degree of the hollow pipe 2 and the wall 1 in connection is further increased, and the hollow pipe 2 is prevented from loosening and shifting to influence the quality of the wall 1; similarly, the outer surface of the reinforcing pipe 6 is corrugated, so that the contact area between the sound absorption cotton 8 and the reinforcing pipe 6 can be increased, the stability of the sound absorption cotton 8 during installation is improved, and the sound insulation capability of the wall body 1 is ensured; the corrugated surface can reflect a part of sound waves, so that the noise transmission is further reduced;
meanwhile, the flame-retardant ring 9 is arranged, and because the expanded graphite material has low initial expansion temperature and large expansion volume and is a good flame-retardant material, when fire disaster is caused by electrical abnormity or circuit aging, the volume of the flame-retardant ring 9 is increased and the flame-retardant ring is rapidly expanded, so that the inner diameter of the middle part of the flame-retardant ring 9 is reduced and an electric wire is clamped, the interior of the reinforced pipe 6 is blocked into a plurality of spaces which are not communicated with each other, the fire spread is effectively prevented, and the economic loss is reduced; sodium bicarbonate is heated in the flame-retardant ring 9, when a fire disaster occurs, the sodium bicarbonate is decomposed to generate carbon dioxide gas and water, the carbon dioxide gas isolates oxygen, the fire disaster is convenient to extinguish, and meanwhile, the water absorbs heat to become water vapor, so that the effects of cooling and diluting oxygen are achieved, and the fireproof performance of the reinforced pipe 6 and the wall body 1 is effectively improved; after the sodium bicarbonate particles are subjected to stearic acid modification and coating treatment, the initial decomposition temperature of the sodium bicarbonate can be increased to more than 100 ℃, and the sodium bicarbonate in the flame-retardant ring 9 is prevented from being decomposed due to heat generated during daily use of the wire to influence the flame-retardant effect of the flame-retardant ring 9; meanwhile, related raw materials of the insecticide are added into the flame-retardant ring 9, so that the electric wire can be prevented from being damaged by being bitten by insects and ants in the reinforcing pipe 6, and the service life of the electric wire is prolonged.
