Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a connection mechanism for a precast parapet wall. Background Technology
[0002] A parapet wall is a low wall surrounding the roof of a building. Its main functions include maintaining safety and serving as a waterproof brickwork finish to prevent water seepage from the waterproof layer or rainwater overflow from the roof.
[0003] In reality, parapet walls are generally prefabricated structures with steel bars inserted inside. During actual installation, the steel bars inside the parapet wall are connected to the steel bars inside the wall. However, in the actual installation process, a crane is usually used to lift the parapet wall, and manual assistance is needed to install it into the appropriate position. Because prefabricated parapet walls are heavy, it is difficult to move them manually, which consumes a lot of physical strength and affects the actual assembly efficiency of the parapet wall, resulting in low assembly efficiency.
[0004] To address this issue, we propose a connection mechanism for prefabricated parapet walls. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a connection mechanism for prefabricated parapet walls to assist in the installation of parapet walls and further improve the installation efficiency of parapet walls.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a connection mechanism for a prefabricated parapet wall, comprising a wall panel, a parapet wall body, and a connection structure, characterized in that: a prefabricated hole one and a prefabricated hole two are respectively provided on the outer walls of the wall panel and the parapet wall body; the connection structure includes a prefabricated sleeve and a stabilizing bracket; the prefabricated sleeve is fixedly connected to the prefabricated hole two; a stabilizing rod is fixedly connected to the bottom end of the stabilizing bracket; the stabilizing rod is inserted into the prefabricated hole one; two slide rails are fixedly connected to the side wall of the stabilizing bracket; sliders are slidably connected to the slide rails; a movable shell is fixedly connected between the two sliders; a roller is rotatably installed inside the movable shell; a drive motor and a limiting sleeve are fixedly installed on the outer wall of the movable shell; the output end of the drive motor is fixedly connected to the roller; a tension rope is wound around the outer wall of the roller; a plug is fixedly connected to the movable end of the tension rope; the plug is inserted into both the prefabricated sleeve and the limiting sleeve.
[0007] Preferably, a drive electric cylinder is fixedly installed inside the insert block, and two insert rods are slidably installed inside the insert block. The insert rods are inserted into the prefabricated sleeve, and a connecting rod is hinged between the insert rods and the output end of the drive electric cylinder.
[0008] Preferably, a limiting block is fixedly connected to the bottom end of the prefabricated sleeve, and the limiting block is inserted into the parapet wall body.
[0009] Preferably, the stabilizing bracket has a fixed rod internally connected to it.
[0010] Preferably, a stop cylinder is fixedly installed at the bottom of the movable shell, a fixing block is fixedly connected to the outer wall of the stabilizing bracket, and a stop rod is fixedly connected to the output end of the stop cylinder, with the stop rod and the fixing block being inserted into each other.
[0011] Preferably, the outer wall of the insert has a chamfer.
[0012] Compared with the prior art, this utility model provides a connection mechanism for prefabricated parapet walls, which has the following advantages: In actual use, the connection mechanism of this precast parapet wall only requires inserting the stabilizing rod into the precast hole one, and then inserting the insert block into the precast sleeve inside the parapet wall body. When the drive cylinder works, the insert rod is inserted into the precast sleeve, the drive motor is started, and the roller rotates, which causes the tension rope to move the insert block, thereby moving the parapet wall body towards the wall. No manual assistance is required, which can greatly save manpower and further improve installation efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Example
[0017] Please see Figure 1-4 A connection mechanism for a precast parapet wall includes a wall panel 1, a parapet wall body 2, and a connection structure. The outer walls of the wall panel 1 and the parapet wall body 2 are respectively provided with a precast hole one and a precast hole two. The connection structure includes a precast sleeve 3 and a stabilizing bracket 4. The precast sleeve 3 is fixedly connected to the precast hole two. A stabilizing rod 5 is fixedly connected to the bottom end of the stabilizing bracket 4, and the stabilizing rod 5 is inserted into the precast hole one. Two slide rails 6 are fixedly connected to the side wall of the stabilizing bracket 4, and sliders 7 are slidably connected to the slide rails 6. A movable shell 8 is fixedly connected between the two sliders 7, and a roller is rotatably installed inside the movable shell 8. A drive motor 10 and a limiting sleeve 11 are fixedly installed on the outer wall of the shaft 9 and the movable shell 8. The output end of the drive motor 10 is fixedly connected to the roller 9. A tension rope 12 is wound on the outer wall of the roller 9. A plug block 13 is fixedly connected to the movable end of the tension rope 12. The plug block 13 is plugged into the prefabricated sleeve 3 and the limiting sleeve 11. A drive electric cylinder 14 is fixedly installed inside the plug block 13. Two plug rods 15 are slidably installed inside the plug block 13. The plug rods 15 are plugged into the prefabricated sleeve 3. A connecting rod 16 is hinged between the plug rods 15 and the output end of the drive electric cylinder 14.
[0018] Insert the stabilizing rod 5 into the precast hole 1, and then insert the insert block 13 into the parapet wall body 2. Start the drive cylinder 14, causing the connecting rod 16 to move the insert rod 15, which in turn inserts the insert rod 15 into the precast sleeve 3, thus connecting the insert block 13 and the parapet wall body 2. Then, start the drive motor 10 to rotate the roller 9, which in turn causes the tension rope 12 to move the insert block 13, thus moving the parapet wall body 2 closer to the wall. When the insert block 13 is inserted into the limiting sleeve 11, the parapet wall body 2 can slide downwards. Under the limiting action of the slider 7 and the slide rail 6, the parapet wall body 2 can move downwards in a straight line, which facilitates the precise insertion of the steel bars inside the parapet wall body 2 into the wall. This facilitates the connection between the parapet wall body 2 and the wall. The connection structure can greatly save manpower and improve installation efficiency. It is simple to operate and easy to use.
[0019] Please see Figure 3 and Figure 4 The bottom end of the prefabricated sleeve 3 is fixedly connected to a limiting block 17, which is inserted into the parapet wall body 2.
[0020] The limiting block 17 can provide a limiting effect on the prefabricated sleeve 3 during the process of fixing the prefabricated sleeve 3 into the parapet wall body 2, so that the insertion rod 15 can be accurately inserted into the interior of the prefabricated sleeve 3 during the movement.
[0021] Please see Figure 1 The internal fixed connection of the stabilizing bracket 4 is a fixing rod 18.
[0022] The installation of the fixing rod 18 can improve the structural strength of the stabilizing bracket 4, and further improve its service life.
[0023] Please see Figure 2 and Figure 3 A stop cylinder 19 is fixedly installed at the bottom of the movable shell 8. A fixing block 20 is fixedly connected to the outer wall of the stabilizing bracket 4. A stop rod 21 is fixedly connected to the output end of the stop cylinder 19. The stop rod 21 and the fixing block 20 are inserted into each other.
[0024] Activating the stop cylinder 19 allows the stop rod 21 to be inserted into the fixed block 20, thereby fixing the movable shell 8. This ensures the stability of the movable shell 8 during the movement of the parapet wall body 2, facilitating the subsequent downward movement of the parapet wall body 2.
[0025] Please see Figure 3 The outer wall of the insert 13 has a chamfer 22.
[0026] The chamfer 22 makes it easier to insert the insert 13 into the limiting sleeve 11.
[0027] In summary, the working principle and process of the precast parapet wall connection mechanism are as follows: First, the stabilizing rod 5 is inserted into the wall. Then, the stop cylinder 19 is activated, causing the stop rod 21 to insert into the fixed block 20, connecting the insert block 13 and the parapet wall body 2. The movable shell 8 is then fixed. Next, the drive cylinder 14 is activated, causing the connecting rod 16 to move the insert rod 15, which is then inserted into the precast sleeve 3. Then, the drive motor 10 is activated, causing the roller 9 to rotate, which in turn moves the tension rope 12, thus pulling the parapet wall body 2. After the insert block 13 is inserted into the limiting sleeve 11, the stop cylinder 19 is activated, causing the stop rod 21 to disengage from the fixed block 20. Under the limiting action of the slider 7 and the slide rail 6, the steel bars inside the parapet wall body 2 can be accurately inserted into the required connection position, greatly improving the installation effect of the parapet wall body 2, significantly saving manpower, and facilitating practical use.
[0028] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
