Description

Technical Field

[0001] This utility model relates to the field of prefabricated building components technology, and specifically discloses an anti-floating device for corrugated pipes in the production of prefabricated hollow walls. Background Technology

[0002] Prefabricated buildings, as an emerging energy-saving, environmentally friendly, and green building system, have been widely applied. Precast hollow walls, as special precast components with internal corrugated pipes, require the corrugated pipes to be placed in precast molds before concrete pouring. However, during concrete pouring and vibration, the corrugated pipes may shift downwards or upwards, making it impossible to effectively fix their position. Once the corrugated pipes shift, it increases the difficulty of subsequent wall assembly operations, and may even prevent accurate alignment.

[0003] Utility model patent application number 202021681611.4 discloses a prefabricated wall panel sleeve fixing fixture, including a support rod and a fixing component slidably connected to it for connecting the sleeve. The fixing component and the sleeve are detachably connected. One end of the support rod can slide along the side mold of the precast mold. The fixing component includes a stud, a pull rod, a spring, a limiting plate, a sleeve, an upper handle, and a lower handle. The two ends of the sleeve are respectively connected to the center positions of the limiting plate and the lower handle. The lower end of the pull rod passes through the limiting plate, the sleeve, and the lower handle and is connected to the center position of the upper end face of the stud. The upper end is fitted with a spring and connected to the center position of the upper handle. The prefabricated wall panel sleeve fixing fixture disclosed in this patent can accurately adjust the position of the fixing component relative to the sleeve, and then use the fixing component to move the sleeve upward and limit it, which can solve the problem of the sleeve floating during concrete pouring. However, there are still some shortcomings. First, precast hollow walls typically have at least four sleeves (corrugated pipes) inside, and the existing fixture cannot simultaneously secure all of them. Second, during concrete pouring and vibration, not only does the pipes float, but they may also sink under external forces during vibration, and the existing fixture cannot effectively address this sinking issue. Third, for large-sized precast hollow walls, the internal sleeves are correspondingly longer, and using fixing components to secure the sleeves at a single point is insufficient. Therefore, to address the aforementioned shortcomings of existing precast wall panel sleeve fixing fixtures, this application proposes an anti-floating device for corrugated pipes in the production of precast hollow walls that can effectively solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-floating device for corrugated pipes in the production of precast hollow walls, so as to solve the problem that multiple corrugated pipes inside the existing precast hollow wall production process cannot be effectively fixed, resulting in the displacement of the corrugated pipes after molding and affecting product quality.

[0005] This utility model is achieved through the following technical solution:

[0006] A device for preventing the floating of corrugated pipes in the production of precast hollow walls includes a track frame installed on the base plate of the mold table. The track frame spans the forming mold groove and is perpendicular to the corrugated pipe inside the forming mold groove. The track frame is provided with a plurality of movable seats. Each movable seat is provided with a sliding mechanism that matches the track frame and a locking mechanism for locking the position of the movable seat.

[0007] Both ends of the movable seat are connected to arms parallel to the bellows. The ends of the arms are threaded with vertically downward adjusting screws, and the lower ends of the adjusting screws are connected to pressure pads. The ends of the arms are fixedly connected to wheel seats. One end of the wheel seat is rotatably connected to a rope unloading wheel, and a lifting rope is wound on the rope unloading wheel. A locking pin for locking the rope unloading wheel is provided on the wheel seat on the opposite side of the rope unloading wheel.

[0008] As a further feature of the above solution, the sliding mechanism includes two rows of rollers rotatably disposed at both ends of the movable seat, and the two rows of rollers are matched with the roller grooves on both sides of the upper end of the track frame.

[0009] As a further provision of the above solution, the locking mechanism includes a nut block disposed on the upper surface of the movable seat, wherein a locking bolt is threadedly connected to the nut block, extending into the movable seat and abutting against the track frame.

[0010] As a further feature of the above solution, the boom adopts a telescopic sleeve structure.

[0011] As a further provision of the above solution, the locking pin is connected to the wheel seat by a threaded connection to achieve axial movement, or it is connected to the wheel seat by a spring-loaded pull-out mechanism to achieve axial movement.

[0012] As a further feature of the above solution, the lower ends of both sides of the track frame can be detachably installed on the base plate of the mold table by means of bolt connection.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The fixing device disclosed in this utility model uses an adjusting screw to push the pressure pad downwards, making it contact the top of the corrugated pipe to limit the upward movement of the corrugated pipe. On the other hand, it uses a lifting rope removed from the unloading wheel to lift the corrugated pipe and limit its downward movement. Through the combined action of these two methods, the corrugated pipe can be effectively restricted to a set position, thereby solving the problem of corrugated pipe displacement during concrete pouring or vibration, and effectively ensuring the quality of the final product.

[0015] The track frame of this invention can be equipped with multiple fixing devices simultaneously, allowing each device to secure and restrict a single corrugated pipe, thereby effectively ensuring the precise positioning of all corrugated pipes in the precast hollow wall. Furthermore, combined with the telescopic design of the boom, when fixing corrugated pipes of different lengths, the length of the boom can be adjusted so that the pressure pads and suspension ropes at the ends of the two booms can be positioned appropriately to restrict and fix the corrugated pipes, effectively ensuring the fixing effect and expanding its applicability.

[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-3 This application will be described in detail with reference to the embodiments. Example 1

[0022] Example 1 discloses an anti-floating device for corrugated pipes in the production of precast hollow walls. The following description, in conjunction with the entire precast hollow wall production equipment, includes a mold base plate 1. Four L-shaped end mold edges 2 are fixedly installed on the upper surface of the mold base plate 1 via bolts. These four end mold edges 2 form a forming mold groove for casting the precast hollow wall. Multiple crisscrossing wall reinforcement bars 3 are arranged in the forming mold groove, and several corrugated pipes 4 are arranged side-by-side between the upper and lower layers of wall reinforcement bars 3. The two ends of the corrugated pipes 4 are fitted against the inner wall of the corresponding end mold edge 2 to prevent concrete from entering the corrugated pipes 4 during the pouring process. The specific number and position of the corrugated pipes 4 are determined according to the design requirements of the precast hollow wall.

[0023] The fixing device includes a track frame 5 that spans the forming mold groove and is perpendicular to the direction of the corrugated pipe 4. The lower ends of both sides are detachably mounted on the upper surface of the mold base plate 1 by bolts. Several movable seats 6 are provided at the upper end of the track frame 5, and the number of movable seats 6 is equal to the number of corrugated pipes 4 arranged in the forming mold groove.

[0024] The movable seat 6 is equipped with a sliding mechanism that matches the track frame 5 and a locking mechanism for locking the position of the movable seat 6. Specifically, the sliding mechanism includes two rows of rollers 7 rotatably mounted at both ends of the movable seat 6, and these rollers 7 match the roller grooves on both sides of the upper end of the track frame 5. The locking mechanism includes a nut block 8 fixed to the upper surface of the movable seat 6, with a locking bolt 9 threaded into the nut block 8 and extending into the movable seat 6. When the locking bolt 9 is screwed down, it presses against the upper surface of the track frame 5, thereby using friction to fix the movable seat 6. Furthermore, to prevent the lower end of the locking bolt 9 from directly acting on the upper surface of the track frame 5 and causing scratches, a rubber gasket (not shown in the figure) can be connected to the lower end of the locking bolt 9.

[0025] Arms 10, parallel to the bellows 4, are connected to both outer surfaces of the movable base 6. A vertically arranged adjusting screw 11 is threaded to the end of each arm 10, and a pressure pad 12 is connected to the lower end of the adjusting screw 11. The horizontal height of the pressure pad 12 can be adjusted by rotating the adjusting screw 11. Simultaneously, a wheel seat 14 is fixedly connected to the outer end of the arm 10 via a vertically downward connecting rod 13. A rope unloading wheel 15 is rotatably connected to one end of the wheel seat 14, and a lifting rope 17 is wound around the rope unloading wheel 15. Furthermore, a locking pin 16 for locking the rope unloading wheel 15 is provided on the wheel seat 14 opposite the rope unloading wheel 15. Specifically, the locking pin 16 can be axially moved by a threaded connection or by a spring and pull mechanism, thereby pressing against the rope unloading wheel 15 to prevent it from rotating.

[0026] Finally, in order to ensure that the fixing device can effectively fix corrugated pipes 4 of different lengths and prevent the corrugated pipes from changing position during concrete pouring or vibration, the boom 10 in this embodiment 1 can also adopt a telescopic sleeve design, which can effectively adjust the axial position of the adjusting screw 11 and the unloading wheel 15 relative to the corrugated pipe 4.

[0027] The specific usage method and working principle of the fixing device disclosed in Embodiment 1 are as follows:

[0028] S1: First, a forming mold groove is formed on the upper surface of the mold base plate 1 by four end mold edges 2, and then wall steel bars 3 and corrugated pipes 4 are arranged in the forming mold groove.

[0029] S2: Next, fix the track frame 5 across the forming mold groove on the mold base plate 1, and make the track frame 5 perpendicular to the arrangement direction of the corrugated pipe 4. After the track frame 5 is fixed, according to the number of corrugated pipes 4 in the forming mold groove, install the corresponding number of movable seats 6 on the track frame 5, and then move each movable seat 6 to be aligned vertically with the corrugated pipe 4. After alignment, lock and fix it through the locking mechanism.

[0030] S3: Then, pull the lifting rope 17 on the unloading rope wheel 15 to a certain length, wrap it around one end of the corrugated pipe 4 and tie it in place. Then, rotate the unloading rope wheel 15 to wind up the remaining lifting rope 17, thereby lifting the corrugated pipe 4 with the lifting rope. Next, rotate the adjusting screw 11 to move the pressure pad 12 down, so that the lower end of the pressure pad 12 contacts the upper end of the corrugated pipe 4. Thus, the lifting rope 17 and the pressure pad 12 work together to effectively restrict the up and down movement of the corrugated pipe 4, preventing the corrugated pipe 4 from deforming and floating during concrete pouring and vibration.

[0031] S4: Pour concrete into the molding mold and vibrate to fill it. Before the concrete hardens, lift the pressure pad 12 upward to separate it from the concrete material. The hanging rope 17 can be untied and pulled out of the concrete, or the hanging rope 17 can be cut directly and left in the concrete.

[0032] S5: Finally, after the concrete has solidified and formed the wall, remove the end mold edge 2, and then the formed wall can be taken out.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
