Example one
Referring to fig. 1, a cement prefabricated thin-walled component according to an embodiment of the present application includes a component body 10, and a plurality of air flow grooves 11 are formed in an outer wall of the component body 10 along a length direction thereof. The air flow formed by the air flow grooves 11 reduces the surface temperature of the cement prefabricated thin-wall component, and the method is simple, convenient and low in cost, and solves the problem that the fireproof heat-insulating performance detection standard can be reached only by using fireproof heat-insulating mortar or an internal heat-insulating material and an air layer or an external heat-insulating layer under a certain thickness of the existing cement prefabricated thin-wall component.
As shown in fig. 1, a plurality of air flow grooves 11 are uniformly distributed along the length direction of the member body 10. Of course, the air flow grooves 11 may also be distributed unevenly.
In this embodiment, the outer wall of the member body 10 is undulated, and the valley between two peaks is formed as the above-mentioned airflow groove 11. The cross section of the airflow groove 11 is U-shaped. Of course, the cross-section of the air flow groove 11 may be triangular, semicircular, or irregular. It is sufficient that the air flow groove 11 through which the air flow can flow is formed in the outer wall.
In the present embodiment, the depths of the plurality of air flow grooves 11 are the same, but may not be completely the same.
In this embodiment, the cross section of the member body 10 is closed and rectangular. The cross section of the member body 10 may be an outer square and an inner circle, or a polygonal closed shape. When the closed component main body 10 is installed, the component main body directly penetrates through a reserved hole of a floor slab to be superposed to form a common exhaust pipeline.
In this embodiment, the component body 10 is provided with a reinforcement to improve the strength of the thin-walled component and prevent damage during transportation or installation. Specifically, the reinforcement is at least one of steel bars, steel wires, steel bar meshes, fibers, fiber tows, fiber mesh fabrics, non-woven fabrics, metal thin strips, perforated thin strips, packaging belts, woven belts and straws.
Example two
Referring to fig. 2, a prefabricated cement thin-walled component according to the second embodiment of the present application is different from the first embodiment in that the cross-sectional shape of the component main body 10 is different, and the cross-sectional shape of the component main body 10 is non-closed, i.e., L-shaped. When being installed, the L-shaped component main body 10 penetrates through the reserved opening of the floor slab to be surrounded and overlapped with the internal corner wall of a room to form a common exhaust pipeline.
In this embodiment, the L-shaped member main body 10 is assembled and combined. Of course, it may be integrally formed.
Other structures in this embodiment are the same as those in the first embodiment, and are not described herein.
EXAMPLE III
Referring to fig. 3, a prefabricated concrete thin-walled component according to a third embodiment of the present invention is different from the second embodiment in that both ends of an L-shaped component body 10 in a longitudinal direction thereof are provided with raised edges 13, respectively. Specifically, the L-shaped member body includes two flat plates 12 perpendicular to each other, and the end portions of the two flat plates 12 are provided with a raised edge 13 along the length direction. The edge-picking 13 forms a reinforcing wing at the end of the two flat plates 12, thereby effectively improving the shock resistance and the pressure resistance of the L-shaped cement prefabricated thin-wall component, preventing the L-shaped cement prefabricated thin-wall component from cracking, improving the mechanical property of the L-shaped cement prefabricated thin-wall component, greatly increasing the sealing area of the intersection of the straight end surfaces of the two flat plates 12 and the wall surface, and enhancing the firmness and the reliability of sealing.
In this embodiment, the two side edges 13 are perpendicular to the plate 12. Of course, there may be other angles between the edge 13 and the plate 12.
Other structures in this embodiment are the same as those in this embodiment, and are not described herein.
Examples four, five and six
Referring to fig. 4 to 6, a prefabricated cement thin-walled component provided in the fourth, fifth and sixth embodiments of the present application is different from that provided in the third embodiment in that an angle between the overhanging edge 13 and the flat plate 12 is different. In the fourth embodiment corresponding to fig. 4, the inner included angle between the inner wall of the overhanging edge 13 and the inner wall of the flat plate 12 is an obtuse angle, so that an acute angle is formed between the outer wall of the overhanging edge 13 and the wall surface, cement mortar is injected into the acute angle for sealing when the cement prefabricated thin-wall component is installed, the sealing area of the intersection of the straight end surfaces of the two flat plates 12 and the wall surface is increased, and the firmness and reliability of sealing are enhanced. In the fifth embodiment corresponding to fig. 5, the edge-picking 13 extends to the outside of the member body, i.e. the angle between the inner wall of the edge-picking 13 and the inner wall of the plate 12 is 270 °. In the sixth embodiment shown in fig. 6, the overhanging edges 13 at the ends of the flat plates 12 extend both outward and inward, so that the impact resistance and pressure resistance of the L-shaped member body 10 are further enhanced, and the sealing performance between the overhanging edges 13 and the wall is further enhanced.
The other structures in the fourth, fifth and sixth embodiments are the same as those in the second embodiment, and are not described herein.
The application also provides an exhaust duct, and the exhaust duct passes the prefabricated thin-walled component of cement floor slab and reserves the entrance to a cave stack formation or encloses and closes room reentrant corner wall and passes the floor slab and reserve the entrance to a cave stack formation.
Further, when the exhaust duct is formed by stacking, a plastering layer or a facing brick is adhered to the outer wall of the member main body 10 of each cement prefabricated thin-wall member, and an air heat insulation layer is formed between the plastering layer or the facing brick and the airflow groove 11. Therefore, the air heat insulation layer arranged between the formed plastering layer or the facing brick on the surface of the exhaust pipeline and the airflow groove 11 reduces the heat dissipation in the exhaust pipeline, and the exhaust pipeline is more comfortable, more energy-saving and more environment-friendly to live in.
The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
