[0033] Example 1
[0034] For easier understanding, see Figure 1-Figure 3 The utility model provides an embodiment of a pre-embedded joint fixing device, comprising: a base 10, a slurry-proof cover 20 and a limit block 30; wherein,
[0035] The base 10 includes a fixed disc 101 and a support rod 102; a first end of the support rod 102 is provided with a plurality of continuous tooth grooves, and a second end of the support rod 102 is connected to the fixed disc 101; a casting template 60 is detachably connected to the bottom surface of the fixed disc 101;
[0036] The anti-slurry cover 20 is provided with a limiting through hole 200, and the first end of the support rod 102 extends out from the limiting through hole 200;
[0037] The support rod 102 is sleeved with an embedded joint 70, and the anti-slurry cover 20 is arranged on the upper side socket of the embedded joint 70;
[0038] The limiting block 30 is elastically connected to the top surface of the anti-slurry cover 20 , and the tooth groove of the support rod 102 is clamped by the limiting block 30 .
[0039] Specifically, the size of the limiting through hole 200 matches the size of the support rod 102 , so that the first end of the support rod 102 can extend from the limiting through hole 200 of the anti-slurry cover 20 .
[0040] In some embodiments, the embedded joint fixing device of the utility model is suitable for embedded joint pipe fittings with mainstream heights such as 10 mm, 110 mm, 120 mm, 130 mm, 140 mm, and 150 mm.
[0041] The embedded joint fixing device of the utility model is a fast-assembly and fast-disassembly structure of a toothed type, which is easy to assemble and disassemble and can be recycled, thereby saving the installation cost of the project. After using the embedded joint fixing device of the utility model, it is not necessary to use nails to fix the embedded joints in the construction of the local lowering caisson of the bathroom, so it is not necessary to pry away the nails when removing the casting formwork, thereby reducing the risk of damage to the embedded joints.
[0042] The embedded joint fixing device of the utility model is provided with a slurry-proof cover structure, and when pouring the caisson, the embedded joint does not need to use an additional slurry-proof cover to cover cement, which can effectively save pipe fittings and processes.
[0043] Example 2
[0044] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:
[0045] like Figure 1 As shown, as a preferred implementation, based on the above-mentioned method, further, a plurality of fixing holes 1011 are evenly distributed on the fixing disk 101 .
[0046] In some embodiments, the plurality of fixing holes 1011 may be arranged in a uniform distribution along the circumference of the fixing disk 101. The number of the fixing holes 1011 may preferably be 4. The fixing holes 1011 are provided with self-tapping screws 80.
[0047] It should be noted that the support rod 102 is provided with teeth and the use of the matching stopper 30 plays the role of fixing the anti-slurry cover 20; the fixed disc 101 is evenly distributed with a plurality of fixing holes 1011, and the self-tapping screws 80 fix the fixed disc 101 on the casting template 60 through the fixing holes 1011; the casting template 60 is an aluminum plate for casting a wooden board or an aluminum mold. According to the size of the embedded joint 70, the outer diameter of the fixed disc 101 is smaller than the inner diameter of the lower side socket of the embedded joint 70 (approximately equal to the outer diameter of the riser), and the anti-slurry cover 20 covers the upper side socket of the embedded joint 70, which plays the role of preventing cement mortar from entering the embedded joint 70.
[0048] like Figure 1-3 As shown, as a preferred implementation, on the basis of the above-mentioned implementation, further, the diameter of the fixed disc 101 is smaller than the inner diameter of the socket of the embedded joint 70 .
[0049] Specifically, the diameter of the fixing disc 101 is slightly smaller than the inner diameter of the socket of the embedded joint 70 , so that the fixing disc 101 can seal the bottom of the embedded joint 70 .
[0050] like Figure 1As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the top surface of the anti-slurry cover 20 is provided with a fixing seat 40 and a spring piece 50; the fixing seat 40 and the top surface of the anti-slurry cover 20 are fixedly connected; the spring piece 50 is installed between the fixing seat 40 and the limit block 30, providing elastic force to make the limit block 30 snap into the tooth groove of the support rod 102 to prevent loosening. The limit block 30 is used to support the tooth groove on the base support rod 102, and has a locking effect.
[0051] In this embodiment, the spring sheet 50 is similar to a V-shaped or U-shaped spring sheet and has resilience. One end of the spring sheet is clamped on the limit block 30 , and the other end is fixed on the fixing seat 40 .
[0052] like Figure 1 As shown, as a preferred embodiment, on the basis of the above method, further, the fixing seat 40 is provided with connecting holes 401 on both sides, the limiting block 30 is provided with a cylinder 301, and the cylinder 301 is installed on the connecting hole 401 of the fixing seat 40, so that the limiting block 30 can rotate and move on the fixing seat 40.
[0053] It is understandable that when installing the embedded joint fixing device, the limit block 30 is inserted into the tooth groove of the support rod 102, and the spring sheet 50 elastically fixes the limit block 30. After the anti-slurry cover 20 is installed in place, only when the spring sheet is deformed under the action of external force, the limit block can be unlocked and the anti-slurry cover 20 can be removed, so as to realize the fast installation and disassembly of the embedded joint fixing device. The utility model is quick to install, and the limit block 30 can effectively lock the anti-slurry cover 20 through the spring sheet 50, so that the anti-slurry cover 20 is not easy to loosen.
[0054] like Figure 4b As shown, as a preferred embodiment, based on the above method, further, the spring piece 50 is a metal spring piece. The material of the metal spring piece is metal copper, iron, etc. The embedded joint fixing device is a metal structure with high hardness, which can fix the embedded joint 70 so that it is not easy to loosen.
[0055] like Figure 4a As shown, as a preferred embodiment, on the basis of the above method, further, one side of the limit block 30 is provided with a spring clip position 302 for fixing the spring clip 50, and the spring clip 50 is snapped into the spring clip position 302 of the limit block 30 to prevent the spring clip 50 from falling out.
[0056] The other side of the limit block 30 serves as a support rod clamping position 303 for clamping the tooth groove of the support rod 102 .
[0057] like Figure 4a As shown, as a preferred embodiment, based on the above method, further, the spring piece clamping position 302 is a groove. The groove is a concave structure, which is convenient for the spring piece 50 to be clamped.
[0058] like Figure 4a As shown, as a preferred implementation, based on the above method, further, the groove depth is 0.3-0.5cm.
[0059] It is understandable that, through the spring clip position 302, the spring clip 50 can be effectively limited, so that the contact area between the spring clip 50 and the limit block 30 and the fixed seat 40 is increased, and the spring clip 50 is effectively prevented from being separated from the fixed seat 40 and the limit block 30. Further, it is convenient to assemble and disassemble the spring clip 50 between the limit block 30 and the fixed seat 40. When the depth of the spring clip position 302 is too shallow, the spring clip 50 is easy to be separated from the spring clip position 302, and when the depth of the spring clip position 302 is too large, it is not convenient to disassemble and install the spring clip 50. The depth of the spring clip position 302 can be set to 0.3-0.5 cm, which can meet the limit requirements of the spring clip 50 and facilitate the removal of the spring clip 50 from the spring clip position 302.
[0060] like Figure 1 As shown, as a preferred embodiment, based on the above method, further, the anti-slurry cover 20 is disc-shaped, and a socket portion 201 is provided on the side facing the base 10, and the outer diameter of the socket portion 201 is smaller than the inner diameter of the upper socket of the embedded joint 70.
[0061] In this embodiment, the outer diameter of the socket portion 201 is equal to the outer diameter of the vertical pipe. When installing the embedded joint fixing device, the socket portion 201 is inserted into the socket of the embedded joint 70 to fix the embedded joint 70 and prevent cement mortar from entering the interior of the embedded joint 70.
[0062] Example 3
[0063] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below:
[0064] like Figure 5 As shown, as a preferred implementation, based on the above method, further, the installation steps of the utility model are:
[0065] STEP 1: The base 10 is fixed to the wooden board by self-tapping screws 80;
[0066] STEP 2: Install the embedded joint 70 on the base 10;
[0067] STEP 3: Insert the anti-slurry cover 20 with the limit block 30 installed on the embedded joint 70; the first end of the support rod 102 extends from the limit through hole 200, and the limit block 30 is stuck in the tooth groove of the support rod 102;
[0068] STEP 4: Pour cement around the embedded joint 70;
[0069] STEP 5: After the cement is dry, press the limit block 30 so that the limit block 30 no longer blocks the support rod 102, and remove the anti-slurry cover 20;
[0070] STEP 6: Remove the casting template 60 and the base 10;
[0071] STEP7: At this point, other drainage components such as risers and tees can be installed.
[0072] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
