Description

Technical Field

[0001] The utility model belongs to the technical field of building pipeline protection, in particular to a protective device for exposed drainage pipes outside a wall. Background Art

[0002] In modern buildings, drainage pipes are one of the important infrastructures. However, due to design and construction limitations, the drainage pipes of many buildings are exposed outside the walls. When the first floor of a high-rise building is designed as an elevated floor, it is used as a place for exercise activities, with a variety of exercise equipment and children's toys. Exposed water pipes not only affect the beauty of the building, but also bring potential safety risks to the pipes themselves and the surrounding environment. Exposed drainage pipes are easily damaged by external physical impacts, and under the influence of environmental conditions such as temperature changes, they may generate noise, affecting the quality of life of residents.

[0003] To solve the above problems, some existing solutions focus on enhancing the strength and durability of the pipes themselves, such as using stronger materials or adding protective layers. However, these methods often increase the difficulty and cost of construction, and do not fundamentally solve the appearance and noise problems. On the other hand, some solutions try to reduce noise by adding sound insulation materials, but these methods usually only focus on sound isolation and ignore other factors, such as insulation and installation convenience.

[0004] Therefore, developing a protective device for exposed drainage pipes outside the wall that can effectively protect the exposed drainage pipes from physical damage, has good sound insulation and heat preservation performance, is easy to install, and has high adaptability and safety has become an urgent problem to be solved by those skilled in the art. To this end, this application document provides a protective device for exposed drainage pipes outside the wall. Utility Model Content

An annular groove 31 is provided on the connecting bolt 3. The open ends of the two semicircular protective pipe covers 1 are butted. The threaded end of the connecting bolt 3 passes through the rear annular groove 31 of the two semicircular protective pipe covers 1 and a retaining ring 4 is installed. The connecting bolt 3 is connected and fixed to the wall fixing seat 2 by at least two locking nuts 5. Among them, the semicircular protective pipe cover 1 comprises a semicircular thin-walled tube body 11. Thickened portions 12 are provided on the inner walls at both ends of the axial direction of the semicircular thin-walled tube body 11. Two pairs of right-angle grooves 13 are provided on the outer wall of the semicircular thin-walled tube body 11 and the thickened portion 12. A circular through hole 14 that penetrates the semicircular thin-walled tube body 11 and the thickened portion 12 is provided on the inner wall of the right-angle groove 13. Two semicircular protective pipe covers 1 are butt-jointed and fixed with four sets of connecting bolts 3 and retaining rings 4 to form a protective structure for the outside of the exposed drainage pipe outside the wall, and the gap between the semicircular protective pipe cover 1 and the drainage pipe is not less than two centimeters. The wall fixing seat 2 is stably installed on the wall by expansion bolts, and the connecting bolts 3 and the wall fixing seat 2 are fastened together by locking nuts 5 to stably fix the semicircular protective pipe cover 1 on the outside of the exposed drainage pipe outside the wall, and the semicircular protective pipe cover 1 directly withstands impact. Multiple protective devices of this embodiment can be used for one exposed drainage pipe.

[0031] Among them, a row of positioning slots 15 are provided on the common end face of the semicircular thin-walled tube body 11 and the thickened portion 12. The two semicircular protective tube covers 1 are connected as a whole through two rows of connecting columns. By providing the positioning slots 15 on the butt end face of the semicircular thin-walled tube body 11 and connecting them as a whole using two connecting columns, the overall structure has good stability and convenient installation.

[0032] The wall fixing seat 2 includes a rectangular plate body 21. Four positioning holes 22 are provided on the rectangular plate body 21. An H-shaped plate 23 is fixed at the center of the rectangular plate body 21. At least two pairs of rectangular extension plates 24 are symmetrically fixed on the two sides of the H-shaped plate 23. The rectangular extension plates 24 are provided with oblong holes 25. The oblong holes 25 provided on the rectangular extension plates 24 on both sides of the wall fixing seat 2 are suitable for installation and positioning of the semicircular protective pipe cover 1 within a certain diameter range.

[0033] For the sake of safety and aesthetics, the end cap of the connecting bolt 3 is a rectangular structure, and the end cap structure is the same as the right-angle groove 13 structure, that is, the outer contour of the end cap of the connecting bolt 3 is the same as the outer contour of the semicircular protective tube cover 1. From the appearance, the connecting bolt 3 is more integrated with the semicircular protective tube cover 1 after installation, and its outer side forms a smooth cylindrical surface without a protrusion, which is safe and beautiful. The retaining ring 4 installed after the rod body of the connecting bolt 3 passes through the two semicircular protective tube covers 1 fits tightly on the inner side of the right-angle groove 13. Four pairs of connecting bolts 3 and retaining rings 4 cooperate to stably connect the two butted semicircular protective tube covers 1 into one.

[0034] In order to further isolate the noise of the drain pipe, sound insulation cotton is filled between the inner side of the semicircular protective pipe cover 1 and the outer wall of the drain pipe. In addition, the filled sound insulation cotton can play a heat preservation effect in combination with the semicircular protective pipe cover 1.
