Description

Technical Field

[0001] This utility model relates to the field of building grouting sleeve technology, and in particular to a prefabricated building grouting sleeve. Background Technology

[0002] Grouting sleeves, also known as grouting sleeve joints or sleeve grouting joints, are assemblies composed of specially processed sleeves, matching grouting materials, and reinforcing bars. When connecting reinforcing bars, fast-hardening, non-shrink grouting material is injected, and the reinforcing bars are connected to the sleeve by the bonding and interlocking effect between the materials. Grouting sleeve joints have the advantages of reliable performance, wide applicability, and easy installation. When grouting the grouting sleeve, the grouting pipe of the grouting machine must be connected to the grout inlet of the grouting sleeve.

[0003] However, existing grouting methods involve workers manually inserting grouting pipes into the inlet. During the grouting process, the grouting pipes need to be kept in place to prevent them from falling off, which is quite laborious. After grouting is completed, the inlet and outlet are usually blocked with rubber stoppers. However, the rubber stoppers may be pushed out by the solidifying grout. Therefore, a prefabricated building grouting sleeve is needed. Utility Model Content

[0004] The purpose of this utility model is to provide a prefabricated building grouting sleeve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a prefabricated building grouting sleeve, comprising a grouting sleeve body, a first reinforcing bar movably installed inside the grouting sleeve body, a second reinforcing bar movably installed inside the grouting sleeve body, a grout inlet pipe fixedly installed on the grout inlet pipe, a limiting groove formed on the limiting groove, a first fixing groove formed on the limiting groove, a fixing block slidably installed in the first fixing groove, a baffle slidably installed in the limiting groove, the fixing block fixedly installed on the baffle, a pull handle fixedly installed on the baffle, a grouting pipe provided on one side of the grout inlet pipe, a connecting mechanism provided at the end of the grouting pipe near the grout inlet pipe, and a blocking mechanism provided on the grouting sleeve body.

[0006] Preferably, the connecting mechanism includes a second fixing groove formed on the slurry inlet pipe, and a first fixing pipe is fixedly installed on the slurry inlet pipe.

[0007] Preferably, a dial ring is slidably installed on the grouting pipe, a pressure ring is fixedly installed inside the dial ring, a first spring is fixedly installed on the pressure ring, the other end of the first spring is fixedly installed on the grouting pipe, a second fixing pipe is fixedly installed on the grouting pipe, a fixing ball is movably installed inside the second fixing pipe, and a rubber pad is fixedly installed inside the second fixing pipe.

[0008] Preferably, the blocking mechanism includes a grout outlet fixedly installed on the grouting sleeve body, a support block fixedly installed on the grout outlet, a support rod fixedly installed on the support block, a connecting flexible strip rotatably installed on the support rod, and a cap plug fixedly installed at the other end of the connecting flexible strip, the cap plug being slidably installed inside the grout outlet.

[0009] Preferably, a limiting block is fixedly installed on the slurry outlet, and a limiting strip is fixedly installed on the cap, with the limiting strip slidably installed inside the limiting block.

[0010] Preferably, a sliding rod is slidably installed inside the limiting block, and a connecting block is fixedly installed at one end of the sliding rod.

[0011] Preferably, a second spring is fixedly installed on the inner side of the connecting block, the other end of the second spring is fixedly installed on the limiting block, and a pull block is fixedly installed on the outer side of the connecting block.

[0012] The beneficial effects of this utility model are:

[0013] In this invention, through the structural arrangement of the connecting mechanism, the first and second reinforcing bars are inserted into the grouting sleeve body. By manually moving the dial ring, the first fixing pipe is inserted into the second fixing pipe. When the dial ring is released, due to the setting of the first spring, the fixing ball is pressed into the second fixing groove, thereby connecting the grouting pipe to the grout inlet pipe. By pulling the handle, the baffle is pulled out from the grout inlet pipe, and the grouting machine can be started to grout the grouting sleeve body. In this way, there is no need for manual handling of the grouting pipe to prevent it from falling off, saving manpower.

[0014] In this invention, by pulling the block, the connecting block moves and moves out of the limiting strip. When the connecting block moves out of the limiting strip, the cap can be rotated to observe whether the slurry is full. After it is full, the cap is placed in the slurry outlet, the limiting strip is inserted into the limiting block, and the block is released to fix the cap in the slurry outlet. Then, the baffle is inserted into the limiting groove. This prevents the baffle and the cap from being squeezed out when the slurry solidifies, thus preventing the slurry from flowing out.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example:

[0022] like Figure 1-4 As shown, this embodiment provides a prefabricated building grouting sleeve, including a grouting sleeve body 1, a first reinforcing bar 2 movably installed inside the grouting sleeve body 1, a second reinforcing bar 3 movably installed inside the grouting sleeve body 1, a grout inlet pipe 4 fixedly installed on the grouting sleeve body 1, a limiting groove 5 opened on the grout inlet pipe 4, a first fixing groove 6 opened on the limiting groove 5, a fixing block 7 slidably installed in the first fixing groove 6, a baffle 8 slidably installed in the limiting groove 5, the fixing block 7 fixedly installed on the baffle 8, a pull handle 9 fixedly installed on the baffle 8, a grouting pipe 10 provided on one side of the grouting pipe 4, a connecting mechanism 11 provided at one end of the grouting pipe 10 near the grouting pipe 4, and a blocking mechanism 12 provided on the grouting sleeve body 1;

[0023] Insert the first reinforcing bar 2 and the second reinforcing bar 3 into the grouting sleeve body 1. Connect the grout inlet pipe 4 and the grouting pipe 10 with the connecting mechanism 11. Pull the handle 9 to pull the baffle 8 out of the grout inlet pipe 4. Then the grouting machine can be started to grout the grouting sleeve body 1. The baffle 8 and the blocking mechanism 12 can be used to prevent the grout filling the grouting sleeve body 1 from flowing out.

[0024] In this embodiment of the utility model, specifically, the connecting mechanism 11 includes a second fixing groove 111 opened on the grout inlet pipe 4, a first fixing pipe 112 fixedly installed on the grout inlet pipe 4, a slidable ring 113 slidably installed on the grouting pipe 10, a pressure ring 114 fixedly installed inside the ring 113, a first spring 115 fixedly installed on the pressure ring 114, the other end of the first spring 115 fixedly installed on the grouting pipe 10, a second fixing pipe 116 fixedly installed on the grouting pipe 10, a fixing ball 117 movably installed inside the second fixing pipe 116, and a rubber pad 118 fixedly installed inside the second fixing pipe 116;

[0025] To save manpower, the first reinforcing bar 2 and the second reinforcing bar 3 are inserted into the grouting sleeve body 1. The dial ring 113 is moved by hand, and the movement of the dial ring 113 causes the pressure ring 114 to move. When the pressure ring 114 moves out of the fixed ball 117, the first fixed tube 112 is inserted into the second fixed tube 116, and the second fixed groove 111 is aligned with the position of the fixed ball 117. The dial ring 113 is released, and due to the setting of the first spring 115, the pressure ring 114 will move back to its original position, pressing the fixed ball 117 into the second fixed groove 111, thus fixing the first fixed tube 112 in the second fixed tube 116. Then, the grouting pipe 10 is connected to the grout inlet pipe 4. The handle 9 is pulled to pull the baffle 8 out of the grout inlet pipe 4, and the grouting machine can be started to grout the grouting sleeve body 1. In this way, it is not necessary to manually hold the grouting pipe 10 to prevent it from falling off, thus saving manpower.

[0026] In this embodiment of the utility model, specifically, the blocking mechanism 12 includes a grout outlet 121 fixedly installed on the grouting sleeve body 1, a support block 122 fixedly installed on the grout outlet 121, a support rod 123 fixedly installed on the support block 122, a connecting flexible strip 124 rotatably installed on the support rod 123, a cap 125 fixedly installed at the other end of the connecting flexible strip 124, the cap 125 slidably installed inside the grout outlet 121, a limiting block 126 fixedly installed on the grout outlet 121, a limiting strip 127 fixedly installed on the cap 125, the limiting strip 127 slidably installed inside the limiting block 126, a moving rod 128 slidably installed inside the limiting block 126, a connecting block 129 fixedly installed at one end of the moving rod 128, a second spring 1210 fixedly installed on the inner side of the connecting block 129, the other end of the second spring 1210 fixedly installed on the limiting block 126, and a pull block 1211 fixedly installed on the outer side of the connecting block 129.

[0027] To prevent the grout filling the main body 1 of the grouting sleeve from flowing out, pull the pull block 1211. The pull block 1211 moves the connecting block 129. When the connecting block 129 moves out of the limiting strip 127, rotate the cap 125. Then, use the grout outlet 121 to observe whether the grout is full. After it is full, put the cap 125 over the grout outlet 121. Insert the limiting strip 127 into the limiting block 126. Release the pull block 1211. Due to the setting of the second spring 1210, the connecting block 129 will be inserted into the limiting strip 127, fixing the limiting strip 127 in the limiting block 126. Then, fix the cap 125 in the grout outlet 121. Then insert the baffle 8 into the limiting groove 5. This will prevent the baffle 8 and the cap 125 from being squeezed out when the grout solidifies, causing the grout to flow out.

[0028] Working principle: In use, insert the first reinforcing bar 2 and the second reinforcing bar 3 into the grouting sleeve body 1. Move the dial ring 113 by hand. The movement of the dial ring 113 drives the pressure ring 114 to move. When the pressure ring 114 moves out of the fixing ball 117, insert the first fixing tube 112 into the second fixing tube 116. Align the second fixing groove 111 with the position of the fixing ball 117. Release the dial ring 113. Due to the setting of the first spring 115, the pressure ring 114 will move back to its original position, pressing the fixing ball 117 into the second fixing groove 111. This fixes the first fixing tube 112 into the second fixing tube 116, and then connects the grouting pipe 10 to the grout inlet pipe 4. Pull the handle 9 to pull the baffle 8 out of the grout inlet pipe 4, and the grouting machine can be started to grout the grouting sleeve body 1. This way, it is not necessary to... The grouting pipe 10 is held manually to prevent it from falling off, saving manpower. Pulling the pull block 1211 moves the connecting block 129. When the connecting block 129 moves out of the limiting strip 127, the cap 125 is rotated, and the grout outlet 121 can be used to observe whether the grout is full. After it is full, the cap 125 is placed in the grout outlet 121, and the limiting strip 127 is inserted into the limiting block 126. The pull block 1211 is released. Due to the setting of the second spring 1210, the connecting block 129 will be inserted into the limiting strip 127, fixing the limiting strip 127 in the limiting block 126, and then fixing the cap 125 in the grout outlet 121. Then the baffle 8 is inserted into the limiting groove 5. This prevents the baffle 8 and the cap 125 from being squeezed out when the grout solidifies, causing the grout to flow out.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
