Description

Technical Field

[0001] The utility model relates to the technical field of concrete prefabricated component processing, in particular to a device for accurately forming reserved holes of concrete prefabricated components. Background Art

[0002] When precast concrete components are formed, it is sometimes necessary to reserve some holes on the precast concrete components. When forming these holes, most of the methods are to embed rods that penetrate the precast concrete components during concrete pouring, and then remove the rods after the precast concrete components are solidified to form the reserved holes.

[0003] The current practice is to use pre-hole forming rods for concrete precast components to form pre-holes in concrete. Pre-hole forming rods for concrete precast components are generally directly formed using metal rods and inserted into the concrete precast components with the required holes. After the concrete solidifies, the concrete precast components and the metal rods are tightly solidified together, making it difficult to remove the metal rods from the concrete. Therefore, we propose a precise forming device for pre-holes in concrete precast components to solve the above problems. Utility Model Content

[0010] Preferably, the outer wall of the circular ring is respectively provided with a plurality of ball grooves, in which balls are rotatably installed, and the contact surfaces of the plurality of balls are fitted in the circular chamber of the forming mold plate; the plurality of balls on the outer wall of the circular ring rotate in the inner wall of the circular chamber to realize rotational support for the stainless steel plug rod, reduce the friction between the circular ring on the connecting rod and the circular chamber, and improve the rotation efficiency of the connecting rod.

[0011] Preferably, the spring clamping mechanism includes a limiting collar and a second spring, and the same limiting collar is movably installed in multiple limiting side grooves.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] The device for precisely forming the reserved holes of the concrete precast component can pull up and twist the handle plate on the connecting rod so that the cross-shaped inserting plates on the multiple circular plates are synchronously inserted into the cross-shaped slots of the corresponding cross-shaped inserting frames, and the stainless steel inserting rod is twisted, and the multiple balls on the outer wall of the circular ring on the connecting rod rotate in the inner wall of the circular chamber to support the rotation of the stainless steel inserting rod, reduce the friction between the circular ring on the connecting rod and the circular chamber, and improve the rotation efficiency of the connecting rod.

[0021] Furthermore, a plurality of cross-shaped insertion frames 6 are arranged at equal intervals, and a cross-shaped slot is provided in the cross-shaped insertion frame 6 , so as to facilitate the precise insertion between the cross-shaped insertion board 8 and the cross-shaped slot of the cross-shaped insertion frame 6 .

[0022] Specifically, the corresponding circular plate 7 and cross-shaped plug-in plate 8 are located directly below the corresponding cross-shaped plug-in frame 6 , and the cross-shaped plug-in plate 8 is adapted to the cross-shaped slot of the cross-shaped plug-in frame 6 , so that the cross-shaped plug-in plate 8 can be inserted into the cross-shaped slot of the cross-shaped plug-in frame 6 .

[0023] Specifically, the connecting rod mechanism includes a handle plate 10 and a connecting rod 11. The handle plate 10 is fitted on the top of the stainless steel insertion rod 4, and one end of the connecting rod 11 is fixedly installed on the bottom side of the handle plate 10. The other end of the connecting rod 11 passes through the rod chamber 5 of the stainless steel insertion rod 4 and is fixedly connected to multiple circular plates 7 and multiple cross-shaped insertion plates 8; by pulling the handle plate 10 upward, the connecting rod 11 is driven to move upward, so that the cross-shaped insertion plates 8 on the multiple circular plates 7 are respectively and synchronously inserted into the cross-shaped slots of the corresponding cross-shaped insertion frames 6.

[0024] Furthermore, the outer wall of the ring 3 is respectively provided with a plurality of ball grooves 12, and balls 13 are rotatably installed in the plurality of ball grooves 12, and the contact surfaces of the plurality of balls 13 are fitted in the circular chamber 2 of the forming mold plate 1; the plurality of balls 13 on the outer wall of the ring 3 rotate in the inner wall of the circular chamber 2, thereby realizing rotational support for the stainless steel inserted rod 4, reducing the friction between the ring 3 on the connecting rod 11 and the circular chamber 2, and improving the rotation efficiency of the connecting rod 11.

[0025] Specifically, the spring clamping mechanism includes a limiting ring 15 and a second spring 16. The same limiting ring 15 is movably installed in multiple limiting side grooves 14. One end of the second spring 16 is fixedly installed on the top side of the limiting ring 15, and the other end of the second spring 16 is fixedly installed on the top inner wall of the circular chamber 2. The limiting ring 15 is rotatably sleeved on the stainless steel plug rod 4; the second spring 16 is used to squeeze the ring 3 on the stainless steel plug rod 4 downward, generating a downward force on the stainless steel plug rod 4.

[0026] During use: by inserting the longer end of the stainless steel insertion rod 4 into the concrete precast component, when the concrete precast component is solidified and formed, by pulling up the handle plate 10, the connecting rod 11 is driven to move upward, so that the cross-shaped insertion plates 8 on the multiple circular plates 7 are respectively and synchronously inserted into the cross-shaped slots of the corresponding cross-shaped insertion frames 6. At this time, the two first springs 9 are stressed and deformed and stretched. Afterwards, by screwing the handle plate 10, the multiple cross-shaped insertion plates 8 on the connecting rod 11 drive the stainless steel insertion rod 4 to rotate. At the same time, the ring 3 on the connecting rod 11 rotates in the circular chamber 2 of the forming mold plate 1, so that the multiple balls 13 on the outer wall of the ring 3 rotate in the inner wall of the circular chamber 2, thereby realizing rotational support for the stainless steel insertion rod 4 and lowering the ring 3 on the connecting rod 11 and the circular chamber 2 The friction between them improves the rotation efficiency of the connecting rod 11. At the same time, when the connecting rod 11 is pulled upward, the ring 3 on the connecting rod 11 squeezes the limiting collar 15 upward, causing the limiting collar 15 to move upward in multiple limiting side grooves 14. At this time, the second spring 16 is subjected to force to produce deformation compression, which makes it easy to realize the up and down swinging of the stainless steel plug rod 4 in the process of pulling and twisting the handle plate 10 on the connecting rod 11, which is convenient for cooperating with the rotating stainless steel plug rod 4. Since the surface of the stainless steel plug rod 4 is smooth and has low friction, it reduces the adhesion with the concrete, so that the bonding between the stainless steel plug rod 4 and the solidified concrete precast component is loosened, which makes it easy to pull out the stainless steel plug rod 4 and complete the precise forming of the reserved hole of the concrete precast component.
