Of course, the PVC pipe 20 may be replaced by a pipe made of other materials, and the application is not limited thereto.
Be provided with two PVC rods 30 in the PVC pipe 20, PVC rods 30 is located the both ends of PVC pipe 20, PVC rods 30 is solid, is used for right PVC pipe 20 carries out the shutoff, prevents that the fluid from following the one end flow direction other end of PVC pipe 20. The PVC rod material 30 is a non-crystalline material which is flame-retardant, has good chemical stability and only generates low internal stress of tension crack, is a synthetic resin material which is commonly used in the first place and the second place in the world in China, and can be widely applied to plugging of the pull bolt hole due to the characteristics of excellent flame retardancy, wear resistance, chemical corrosion resistance, low water absorption, convenience in production and processing and the like.
In this embodiment, the lengths of the two PVC bars 30 are equal and are one third of the length of the split bolt hole. It should be understood that the equivalent PVC bar 30 is used to facilitate the standardized production thereof and to improve the replaceability and versatility of the PVC bar 30, and of course, the length of the PVC bar 30 may be longer than one third of the length of the split bolt hole or shorter than one third of the length of the split bolt hole, which is not limited in any way by the present application. The lengths of the two PVC bars 30 may be equal or unequal, which is not limited in this application.
In this embodiment, the difference between the diameter of the PVC bar 30 and the diameter of the PVC pipe 20 is between 0.5mm and 1.5mm, so that the PVC bar 30 can be easily inserted into the PVC pipe 20. Meanwhile, glue 40 is filled in a gap between the PVC bar 30 and the PVC pipe 20, so that the PVC bar 30 and the PVC pipe 20 are effectively bonded, the PVC bar 30 and the PVC pipe 20 are integrated, the PVC pipe 20 is completely sealed, and water flow is effectively prevented.
In this embodiment, the glue 40 is a PVC dedicated glue. The special PVC glue is a single-component novel full-transparent solution glue, is a special full-transparent PVC plastic glue 40 product developed for removing a transparent or white PVC plastic product difficult to bond, has the excellent characteristics of room temperature curing, convenient operation, high bonding strength, good water resistance, good corrosion resistance and the like, and realizes seamless plugging between the PVC rod 30 and the PVC pipe 20.
Referring to fig. 1, the two PVC bars 30 are respectively located on the backwater side and the water-facing side of the building wall 10, one end of the PVC bar 30 located on the water-facing side, which is close to the opening of the split bolt hole, is provided with a sand cap 60, and the sand cap 60 is located outside the opening of the split bolt hole. Through setting up sand cap 60 is so that satisfy the requirement that the wall plastered, can also regard as the end cap simultaneously in order to improve waterproof performance.
In this embodiment, the sand cap 60 may be integrally formed with the PVC bar 30, for example, by a casting form during casting. Also can connect structure as an organic whole through connected modes such as bolted connection, buckle connection, for example be provided with the blind hole that is used for connecting on the sand cap 60, be provided with the internal thread in the blind hole, the one end of PVC rod 30 is provided with the external screw thread, through with sand cap 60 screw in the tip of PVC rod 30 is in order to realize connecting. Therefore, the present application does not set any limit on the connection manner of the sand cap 60 and the PVC bar 30.
In this embodiment, the sand cap 60 is in a shape of a circular disk, and the diameter of the sand cap is larger than that of the PVC bar 30, so as to effectively seal the end of the PVC bar 30 located on the water facing side. The material of the sand cap 60 may be PVC, or other materials may be used, such as metal or plastic, which is not limited in this application.
In this embodiment, the surface of the sand cap 60 facing away from the building wall 10 is rough. Because the surface of the subsequent building wall 10 needs to be plastered, the surface of the sand cap 60 deviating from the building wall 10 is designed to be a rough surface so as to prevent hollowing and even dropping during plastering, and the surface of the sand cap 60 deviating from the building wall 10 is more full after plastering, thereby avoiding the generation of annular cracks.
Further, the surface of the sand cap 60 facing away from the building wall 10 is embedded with a plurality of sand grains. The sand grains can be embedded when the sand cap 60 is formed by pouring, so that the surface of the sand cap 60 formed by pouring, which is far away from the building wall 10, is provided with a plurality of bulges to form the rough surface.
