Abstract
Description
Technical Field
[0001] The present invention relates to building decoration materials, and particularly to a recessed waterproof groove. Background Art
[0002] In building decoration, it is often necessary to embed water pipes in the wall. During specific operations, it is necessary to first groove the wall, then fix the water pipe in the groove, then fill the pipe groove with cement mortar to embed the water pipe in the wall, and finally do waterproofing on the wall surface. In actual life, it is found that the wall with water pipes is prone to wall efflorescence or even mildew. However, it is relatively difficult to quickly solve the problem of wall efflorescence or mildew because there are at least the following situations causing this problem: First, when the joint of the water pipe in the wall leaks, water is very easy to enter the interior of the wall, resulting in wall efflorescence or even mildew; Second, when there is thread leakage at the wall surface water outlet, it is not easy to handle the waterproofing at the thread, and water is also easy to enter the interior of the wall, causing the above problems in the wall; Third, when using water outside the wall (such as taking a shower or cleaning tiles), the grooved wall is prone to cracking, causing the wall waterproofing to fail, and water may enter the wall along the gaps between the tiles, thus causing the above problems in the wall; Fourth, when filling the pipe groove with water pipes on the wall with cement mortar, there is a large gap between the back of the water pipe and the wall, and condensation water is generated under the breathing effect of the temperature difference between hot and cold of the water pipe in the gap, resulting in the above problems on the wall surface.
[0003] In the prior art, in order to avoid the above problems in the wall, generally, a waterproof layer is brushed in the pipe groove of the wall. However, since the pipe groove is formed by later chiseling on the wall, the inner wall of the pipe groove is uneven, and a large number of holes are easily left after brushing the waterproof layer in the pipe groove, resulting in the failure of waterproofing. At the same time, using a pipe clip with nails to fix the water pipe will also damage the waterproofing, and the direct contact between the water pipe and the waterproofing will affect the water quality, making it difficult to effectively solve the above problems. Summary of the Invention
[0004] The purpose of the present invention is to provide a recessed waterproof groove to solve the problem that the wall is prone to adverse phenomena such as efflorescence at the place where the water pipe is recessed in the prior art.
[0005] To achieve the above purpose, the basic scheme of the present invention provides a recessed waterproof groove, including a groove body, and a groove flanging part extending towards the outside of the groove mouth is provided at the groove mouth of the groove body, and the groove flanging part is integrally formed with the groove body.
[0006] The beneficial effects of this basic solution are as follows: With such a setting, during use, a pipe groove is cut in the wall, and then the groove body is embedded therein. The waterproof groove is fixed using cement mortar, and at the same time, the groove flanging part is located at the opening of the pipe groove on the wall, so that the groove flanging part is in waterproof lap with the wall surface, and further, the waterproof of the waterproof groove and the wall surface forms an integral body. Furthermore, it avoids the water leakage of the water pipe in the waterproof groove or the water on the outer side of the wall surface seeping into the wall body through the pipe groove of the wall, thus avoiding problems such as alkali return at the place where the water pipe is embedded in the wall.
[0007] Furthermore, the direction in which the groove flanging part extends towards the outside of the groove opening is perpendicular to the direction of the groove opening. With such a setting, when fixing the waterproof groove in the pipe groove on the wall, by using the groove flanging part being in contact with the wall surface at the opening of the pipe groove as a reference to control the embedding depth of the waterproof groove, it is beneficial to keep the embedding depth of the waterproof groove consistent, and further beneficial to the rapid installation and positioning of the waterproof groove. At the same time, when the waterproof groove is installed in the pipe groove on the wall, the groove flanging part covers the opening edge of the pipe groove, and the waterproof layer of the wall surface is lapped with the groove flanging part, so that even if cracks occur at the opening of the pipe groove due to the shrinkage of the filling material, it will not cause the cracking of the wall surface waterproof layer, and further improves the waterproof effect at the pipe groove of the wall.
[0008] Furthermore, a clamping groove is provided on the upper surface of the groove flanging part. With such a setting, the clamping groove will enhance the bonding force between the waterproof layer of the wall surface and the groove flanging part, and is beneficial to avoiding the situation of local waterproof failure caused by the separation between the waterproof layer and the groove flanging part.
[0009] Furthermore, the extending direction of the clamping groove is parallel to the length direction of the groove body. With such a setting, after the groove body is cut off from any position, the position of the clamping groove near the end of the groove body relative to the end of the groove body remains unchanged, so that the groove body and the corresponding connector can be cooperatively connected, improving the practicability of the waterproof groove.
[0010] Furthermore, a groove is provided on the lower surface of the groove flanging part, and the groove is arranged staggered with the clamping groove, making the cross-section of the groove flanging part wavy. With such a setting, it is beneficial to make the overall thickness of the groove flanging part smaller, facilitating the tile pasting construction; at the same time, the cross-section of the groove flanging part is wavy, making the groove flanging part have good ductility to reduce the situation of waterproof cracking failure caused by the cracking of the wall body at the edge of the pipe groove.
[0011] Furthermore, a number of protruding parts are fixedly provided on the outer side of the groove body. With such a setting, it is beneficial to improve the bonding force between the groove body and the cement mortar in the pipe groove of the wall, so that the installation of the groove body is stable and firm.
[0012] Furthermore, the cross section of the trough body is in an arc shape. With such a configuration, when the trough body is inserted into the pipe groove of the wall by pressing, the trough body can resist the large reaction force from the cement mortar, thereby avoiding the phenomenon that the trough body is damaged and cracked during installation, resulting in failure of the waterproofing function.
[0013] Furthermore, a pipe clamp is clamped on the inner side of the trough body. With such a configuration, the water pipe inside the trough body is clamped and fixed by the pipe clamp, so that the water pipe can be fixed without locally damaging the trough body, thereby avoiding weakening the waterproof effect of the trough body and improving the convenience of water pipe installation.
[0014] Furthermore, the pipe clamp includes a bayonet portion, and a strip-shaped limiting portion is fixedly connected to the outer side of the bayonet portion. One end of the limiting portion is tangent to the bayonet portion, and a clearance cavity is arranged between the other end of the limiting portion and the bayonet portion. A limiting boss that is engaged with the limiting portion is arranged on the inner side of the slot body. When the pipe clamp is placed inside the slot body, the limiting portion and the limiting boss are abutted against each other, so that the pipe clamp is clamped and fixed in the slot body. Then the water pipe is clamped into the bayonet portion of the pipe clamp to achieve the installation and fixation of the water pipe in the slot body. With such a setting, the installation and fixation operation of the water pipe in the slot body is more convenient and quick. At the same time, the pipe clamp fixes the water pipe in the slot body through the bayonet portion and the limiting portion, so that the pipe clamp forms an arch bridge support for the water pipe, which is conducive to making the thickness of the end of the pipe clamp away from the opening of the bayonet portion smaller, and then making the slot cavity depth of the slot body as small as possible under the premise of meeting the use requirements, so that the slot depth will not be increased due to the installation of the waterproof slot, thereby reducing the difficulty of excavation construction of the pipe slot.
[0015] The invention also provides a connector matched with the concealed waterproof trough.
[0016] A connector for a concealed waterproof trough includes a connector body provided with an accommodating cavity, and a connector flange portion extending toward the outside of the accommodating cavity is integrally formed on the connector body at the opening of the accommodating cavity. With such a configuration, when the connector is connected to the waterproof trough, the connector flange portion overlaps with the groove flange portion of the waterproof trough, and the connector flange portion is located at the opening of the pipe groove on the wall, so that the connector flange portion overlaps with the waterproof of the wall surface, and then the connector and the wall surface are integrated with each other, thereby preventing the water pipe in the connector from leaking or the water outside the wall surface from penetrating into the wall through the pipe groove of the wall.
[0017] Further, the connecting end of the joint body is provided with a rabbet connecting portion that fits with the inner wall of the waterproof groove. With such a setting, it is convenient for the connector to be assembled with the waterproof groove by pressing through the rabbet connecting portion, so that after the waterproof groove is first installed in the pipe groove dug on the wall, the connector can be assembled and connected with the waterproof groove, and thus the installation and fixing operation of the connector and the waterproof groove on the wall is simple and convenient.
[0018] Further, the accommodating cavity is in the shape of a straight-through groove, a right angle, a T-shape, a double right angle or a semi-through groove. With such a setting, the connector can adopt different accommodating cavities according to needs, so as to be used for connecting waterproof grooves at different positions, thereby improving the waterproof effect at different positions of the pipe grooves on different walls.

DETAILED DESCRIPTION OF THE INVENTION
[0020] In the present invention, the "groove opening of the groove body" refers to the opening facing the outer side of the wall when the groove body is installed in the wall.
[0021] The following is further detailed through specific embodiments: The reference numerals in the accompanying drawings of the specification include: groove body 1, groove flanging part 2, clamping groove 21, groove 22, protruding part 3, limiting boss 4, pipe clamp 5, limiting part 51, bayonet part 52, relief cavity 53, cover plate 6, hook part 61, notch 7, wall body 8, cement mortar 9, waterproof layer 10, water pipe 11, accommodating cavity 12, joint flanging part 13, tongue-and-groove connection part 14, auxiliary support block 15.
[0022] Example 1: Basically as shown in the attached Figures 1 to 4 figures: A concealed waterproof groove, including a groove body 1. In this embodiment, the cross-section of the groove body 1 is in the shape of a superior arc. A plurality of protruding parts 3 are fixedly arranged on the outer side of the groove body 1. In this embodiment, it is preferably that the protruding parts 3 and the groove body 1 are integrally formed; the protruding parts 3 can be rib strips extending along the length direction of the groove body 1, or columnar convex blocks distributed in a dot shape.
[0023] At the notch 7 of the groove body 1, there is a groove flanging part 2 extending towards the outside of the notch 7, and the groove flanging part 2 and the groove body 1 are integrally formed. In this embodiment, the direction in which the groove flanging part 2 extends towards the outside of the notch 7 is perpendicular to the direction of the notch 7, so that when the waterproof groove is clamped in the wall body 8, the direction of the notch 7 is perpendicular to the wall surface, and at the same time the groove flanging part 2 is parallel to the wall surface. An arc transition is adopted between the groove flanging part 2 and the groove body 1. The upper surface of the groove flanging part 2 is provided with a clamping groove 21. In this embodiment, the extending direction of the clamping groove 21 is parallel to the length direction of the groove body 1. The lower surface of the groove flanging part 2 is provided with a groove 22, and the groove 22 and the clamping groove are arranged in a staggered manner, so that the cross-section of the groove flanging part 2 is in a wavy shape.
[0024] A pipe clamp 5 is clamped inside the groove body 1, which is convenient for fixing the water pipe 11 installed in the waterproof groove through the pipe clamp 5. The pipe clamp 5 includes a bayonet part 52 in the shape of a superior arc, and a strip-shaped limiting part 51 is fixedly connected to the outer side of the bayonet part 52. In this embodiment, it is preferably that the bayonet part 52 and the limiting part 51 are integrally formed. One end of the limiting part 51 is tangent to the bayonet part 52, and a relief cavity 53 is arranged between the other end of the limiting part 51 and the bayonet part 52, so that the limiting part 51 and the bayonet part 52 still have a certain deformation space when inside the groove body 1, which is convenient for the installation and disassembly of the pipe clamp 5, and at the same time is also convenient for the bayonet part 52 to fix the water pipe 11. A limiting boss 4 that is clamped and matched with the limiting part 51 is arranged on the inner side of the groove body 1. In this embodiment, the limiting boss 4 is located on the side of the notch 7 close to the inside of the groove body 1. So when the pipe clamp 5 is placed inside the groove body 1, the end of the limiting part 51 away from the bayonet part 52 abuts against the limiting boss 4, so that the pipe clamp 5 is restricted inside the groove body 1 and cannot come out by itself, thereby realizing the clamping connection between the pipe clamp 5 and the groove body 1.
[0025] A cover plate 6 is provided at the slot opening 7 of the trough body 1. The cover plate 6 has a hook portion 61 that is hooked and matched with the limiting boss 4. By covering the cover plate 6 at the slot opening 7, the elasticity of the material of the cover plate 6 itself is utilized to cause a certain elastic deformation so that the hook portion 61 is hooked on the limiting boss 4, thereby realizing the connection and fixation between the cover plate 6 and the trough body 1. When the hook portion of the cover plate is hooked on the limiting boss, it will occupy a certain space of the clearance cavity 53, thereby reducing the moving space of the bayonet portion 52. Then, when a water pipe is clamped and fixed in the bayonet portion 52, the water pipe cannot fall off the bayonet portion 52, thereby improving the reliability of fixing the water pipe. In this embodiment, the trough body 1, the pipe clamp 5 and the cover plate 6 are all made of plastic. A plurality of protrusions are also integrally formed on the side of the cover plate facing away from the hook portion 61 to enhance the bonding force between the cover plate and the cement mortar.
[0026] The specific implementation process is as follows: after the pipe groove is excavated on the wall 8, an appropriate amount of cement mortar 9 is first filled into the pipe groove, and then the waterproof groove is pressed and embedded into the pipe groove of the wall 8 until the groove flange 2 of the waterproof groove fits the wall surface. During the pressing process, the cement mortar 9 is squeezed and flows and fills the gap between the waterproof groove and the inner wall of the pipe groove of the wall 8, so that the outer wall of the groove body 1 of the waterproof groove is wrapped by the cement mortar 9. The raised portion 3 on the outside of the groove body 1 is embedded in the cement mortar 9. After the cement mortar 9 solidifies, the groove body 1 is well combined with the cement mortar 9 through the raised portion 3. The groove flange 2 covers the edge of the pipe groove of the wall 8. When the waterproof layer 10 is brushed on the wall surface, the waterproof layer 10 overlaps with the groove flange 2, so that the waterproof groove and the waterproof layer 10 of the wall surface are integrated. By clamping the pipe clamp 5 into the groove body 1, the water pipe 11 is clamped 5 into the bayonet portion 52 of the pipe clamp 5, so that the water pipe 11 is installed and fixed. When water leaks from the water pipe 11 in the waterproof groove, the leaked water will flow along the waterproof groove to the ground without penetrating into the wall 8 .
[0027] In addition, in order to ensure the stability of the waterproof groove size during packaging, transportation and installation, an auxiliary support block is designed, such as Figure 11 As shown, the auxiliary support block is engaged with the slot on the groove flange portion and covers the slot, so that the size of the slot remains stable.
[0028] Embodiment 2: Figure 5As shown in the figure, a connector for a concealed waterproof groove includes a connector body provided with a receiving cavity 12, and a plurality of protruding portions 3 are fixedly provided on the outer side of the connector body. In this embodiment, the protruding portion 3 and the connector body are integrally formed. The connecting end of the connector body has a rabbet connecting portion that cooperates with the inner wall of the waterproof groove. When the connector body is connected to the waterproof groove, the rabbet connecting portion 14 is attached to the inner wall of the waterproof groove to achieve lapping. When the connector is installed into the pipe groove of the wall 8, the rabbet connecting portion 14 is pressed into the groove body 1 of the waterproof groove to achieve lapping, so that the waterproof groove and the connector can be installed step by step, improving the installation convenience and accuracy. A connector flanging portion 13 extending outward from the opening of the receiving cavity 12 is integrally formed on the connector body. A clamping block for clamping and cooperating with a clamping groove 21 on the groove flanging portion 2 of the waterproof groove is integrally formed on one side of the connector flanging portion 13. When the connector is connected to the waterproof groove, the clamping block is pressed and clamped into the clamping groove 21 to achieve the lapping of the connector flanging portion 13 and the groove flanging portion 2. In this embodiment, the receiving cavity 12 is a semi-through groove-shaped receiving cavity 12. Of course, in other embodiments, the receiving cavity can also be a straight-through groove-shaped receiving cavity 12a (as shown in Figure 6 ), a right-angle-shaped receiving cavity 12b (as shown in Figure 7 ), a T-shaped receiving cavity 12c (as shown in Figure 8 ), or a double right-angle-shaped receiving cavity 12d (as shown in Figure 9 ), etc., to meet the installation requirements of water pipes 11 with different orientations.
[0029] The specific implementation process is as follows: After a pipe groove is dug on the wall surface, the waterproof groove is first installed and fixed in the pipe groove, and the corresponding connector is selected to be connected to the waterproof groove according to the orientation of the water pipe 11. When the connector is connected, an appropriate amount of cement mortar 9 is first filled in the pipe groove, glue is applied to the connector, and then the connector is pressed into the pipe groove, as shown in Figure 10 . The rabbet connecting portion 14 of the connector is attached to the inner wall of the waterproof groove, and at the same time, the connector flanging portion 13 and the groove flanging portion 2 are lapped, and the connector flanging portion 13 covers the edge of the pipe groove opening of the wall 8. The cement mortar 9 is extruded and flows to the gap between the connector and the pipe groove. After the cement mortar 9 solidifies, the installation and fixation of the connector are achieved. When waterproofing the wall surface, the waterproof layer 10 is lapped with the connector flanging portion 13, so that the connector flanging portion 13 and the wall surface waterproof layer 10 form an integral body. With this solution, when water seepage occurs at the joint, water is prevented from seeping into the wall 8 along the pipe groove of the wall 8, thereby improving the waterproof effect of the wall surface.
[0030] The above are only embodiments of the present invention, and common general knowledge such as specific structures and characteristics known in the solutions is not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent.
