Description
Technical Field
[0001] The invention relates to the technical field of partition board production, in particular to a structure for quickly installing and disassembling concrete prefabricated products. Background Art
[0002] In recent years, the means and products of the construction engineering industry have been gradually replaced by green, environmentally friendly and pollution-free new technologies and products, and the use of concrete prefabricated products has been promoted. As a kind of prefabricated product, lightweight partition boards are made of safe and environmentally friendly building gypsum and cement as the main raw materials. Lightweight partition boards need to go through the steps of mold closing, inserting pipe columns, laying mesh cloth, mixing, pouring, pulling out pipes, opening molds, and maintenance to produce. At present, when the partition boards are pulled out of the pipes, the hollow inner wall of the formed partition boards is adhered to the inserted pipe columns, making it difficult to remove the pipe columns. It is necessary to rotate the pipe columns in the mold under the action of external force, which not only reduces the efficiency of pulling out the pipes and increases the difficulty of removing the pipe columns, but also damages the inner wall of the gypsum partition board during the rotation process, affecting the molding quality of the partition board. The existing partition boards need to open the mold after molding, and hang them out for drying after the pipe columns are pulled out. Large machinery needs to be used for lifting during the hanging and drying process, which increases the production cost.
[0003] To solve the above problems, the inventor provides a structure for quickly installing and disassembling concrete prefabricated products. Before pouring cement, the traction rope is pulled to make the pulley drive the piston tube to extend into the first pipe column. The air pressure in the compression chamber increases, so that the plug block drives the first ring block and the second ring block to increase the cross-sectional size. After the wall panel is formed, the traction rope is released to lock the piston tube and move it to the left. The first ring block and the second ring block gradually shrink and return to their initial state, reducing the resistance when the first pipe column is pulled out. The length of the pressure arm is controlled by adjusting the combined length of the column tube and the pressure rod. The column tube and the pressure rod are pressed down to make the ring top block rotate upward to lift the bottom plate. Under the action of gravity, the partition wall panel gradually slides down along the direction of the side panel, thereby improving the demolding efficiency. Summary of the invention

The end of the plug block 56 away from the center of the first pipe column 51 is fixedly connected with the first ring block 57. An arc groove 58 is provided inside the first ring block 57. The arc groove 58 is movably connected with the second ring block 59 inside, so that the second ring block 59 can freely expand and contract inside the arc groove 58.
[0029] See also Figure 2 , Figure 5 and Figure 6 The rear end of the base 1 of the insertion mechanism 5 is provided with a demolding mechanism 6, which includes a ring top block 61, the interior of the ring top block 61 is hollow, and the axis of the ring top block 61 is rotatably connected to a rotating shaft. The ring top block 61 is rotatably connected to the rear end of the base 1 through the rotating shaft, and the rear side of the ring top block 61 is fixedly connected to a pressure rod 62, and the periphery of the pressure rod 62 is movably connected to a column 63. The interior of the column 63 is adapted to the periphery of the pressure rod 62, and the length of the pressure wall is changed by sliding the column 63 on the periphery of the pressure rod 62. A slide groove 64 is provided above the pressure rod 62, and a rectangular frame 65 is movably connected inside the slide groove 64, so that the rectangular frame 65 can slide freely inside the slide groove 64, and a front baffle plate 66 is provided inside the rectangular frame 65, which provides conditions for the rectangular frame 65 to limit the rotation of the front baffle plate 66, and a partition board 7 is provided above the bottom plate 2 to provide a structural basis for the demolding of the partition board 7.
[0030] Working process and principle: Before pouring the lightweight partition board 7, the inserted pipe column needs to be expanded. Since the top of the bottom plate 2 is fixedly connected to the side plate 3, the side plate 3 and the front baffle 66 constitute a pouring space. At this time, the side plate 3 and the front baffle 66 are located in the rectangular frame 65 limit. The side plate 3, the bottom plate 2 and the front baffle 66 together constitute the pouring space. At this time, the first pipe column 51 is inserted into the block 4 located in the middle of the right side plate 3, and the left block 4 of the first pipe column 51 is fixedly connected to the middle of the left side plate 3 through a threaded thread. The first pipe column 51 The piston tube 52 is movably connected to the inner wall of the first tube column 51, and the left end of the piston tube 52 is rotatably connected to the pulley 53. The pulley 53 is pulled by the traction rope 54 to drive the piston tube 52 to gradually extend into the first tube column 51. Since the first tube column 51 has a compression chamber 55, as the piston tube 52 moves rightward and extends into the air column in the compression chamber 55, the plug 56 is gradually extended by the gas pressure. Because the end of the plug 56 away from the center of the first tube column 51 is fixedly connected to the first tube column 51, the plug 56 is gradually extended. The first ring block 57 and the plug block 56 drive the first ring block 57 to extend synchronously, thereby increasing the outer radius of the first pipe column 51, and the second ring block 59 movably connected to the arc groove 58 extends synchronously with the expansion of the first ring block 57. At this time, the cylindrical cross-section size formed by the first ring block 57 and the second ring block 59 increases to the limit size, fixes the position of the traction rope 54, and then locks the length of the piston tube 52 extending into the first pipe column 51. When the casting is completed and the pipe is pulled out, the traction rope 54 is released. At this time, the air pressure in the compression chamber 55 acts as The piston tube 52 is extended to the left to reduce the air pressure in the compression chamber 55. At the same time, the plug block 56 drives the first ring block 57 to contract and restore to the initial position. Since the second ring block 59 is made of elastic material, as the first ring block 57 contracts, the second ring block 59 extends into the arc groove 58, so that the combined size of the first ring block 57 and the second ring block 59 is smaller than the size of the hollow circular hole inside the partition board 7, which is convenient for taking out the first pipe column 51, so as to achieve the effect of easy disassembly and removal of the expansion pipe column, improve the efficiency of pipe pulling and avoid damage to the inner wall of the hollow wall panel during pipe pulling.
[0031] After the first pipe column 51 is taken out, since the front end of the bottom plate 2 is rotatably connected to the top of the base 1, and the rear end of the base 1 is rotatably connected to the ring top block 61, and the outer periphery of the pressure rod 62 is movably connected to the column tube 63, the column tube 63 is slid around the outer periphery of the pressure rod 62 to adjust the combined length of the column tube 63 and the pressure rod 62, thereby controlling the length of the pressure arm. At this time, the end of the ring top block 61 away from the pressure rod 62 abuts against the lower surface of the bottom plate 2, and slides upward out of the rectangular frame 65 under the limit of the slide groove 64 to release the restriction of the front baffle 66 and flip the front baffle 66 forward. At this time, the partition board 7 is located between the side plate 3 and the bottom plate 2, and the column tube 63 and the pressure rod 62 are pressed down, so that the ring top block 61 rotates upward around the axis to lift the bottom plate 2. At this time, the partition board 7 above the bottom plate 2 gradually slides down along the direction of the front baffle 66 under the action of gravity, achieving the effect of facilitating demolding based on the lever principle and improving the demolding efficiency.
[0032] In summary, the structure for quick installation and disassembly of concrete prefabricated products is connected with the piston tube 52 through the internal movability of the first pipe column 51. Before pouring cement, the traction rope 54 is pulled to make the pulley 53 drive the piston tube 52 to extend into the first pipe column 51. At this time, the air pressure in the compression chamber 55 rises to push out the plug block 56, and the first ring block 57 is then expanded outward. Based on the limitation of the arc groove 58, the second ring block 59 is gradually extended to form a cylinder with the first ring block 57. After the traction end of the traction rope 54 is fixed and the hollow wall panel is formed, the traction rope 54 is unlocked. Under the action of the air pressure in the compression chamber 55, the piston tube 52 moves to the left and extends out, and the first ring block 57 and the second ring block 59 gradually shrink and return to the initial state, reducing the resistance when the first pipe column 51 is pulled out, thereby achieving the effect of easy disassembly and removal of the expansion pipe column, improving the efficiency of pipe pulling and avoiding damage to the inner wall of the hollow wall panel during pipe pulling.
[0033] In addition, the structure for quickly installing and disassembling concrete prefabricated products is rotatably connected to the top of the base 1 through the front end of the bottom plate 2. After demolding and pulling out the tube, the rectangular frame 65 slides out upward so that the front baffle 66 is no longer restricted, and the front baffle 66 is rotated forward. At this time, the combined length of the column tube 63 and the pressure rod 62 is adjusted to control the length of the pressure arm, and the column tube 63 and the pressure rod 62 are pressed down. The ring top block 61 is rotated upward to lift the bottom plate 2. At this time, under the action of gravity, the partition board 7 gradually slides down along the direction of the side plate 3, thereby achieving the effect of facilitating demolding based on the lever principle and improving the demolding efficiency.
