Description

Technical Field

[0001] This invention relates to the field of mold technology, specifically to a mold for manufacturing pre-embedded pipeline ALC partition walls. Background Technology

[0002] With the rapid development of prefabricated buildings, ALC partition wall panels are widely used in interior wall engineering due to their advantages such as light weight, convenient construction, energy saving and environmental protection. As the core carrier of water supply, drainage, power supply, heating and other pipelines, the pipelines need to follow the wall layout to extend to the functional areas of each room.

[0003] On-site trenching and pre-embedding technology is a widely used construction technique for pipelines in ALC partition walls. First, the ALC partition walls are assembled and fixed. Then, according to the design drawings, pipeline trenches are excavated on the ALC partition walls using methods such as cutting and chiseling. After the pipelines are fixed in the pipeline trenches, repair materials are used to seal the pipeline trenches. However, the pipeline trenches are prone to cracking later, leading to local damage to the ALC partition walls.

[0004] The factory prefabrication and pre-embedded integrated production technology involves pre-fixing pipelines in the mold according to the design drawings using locators before the ALC partition wall panels are cast and formed. Then, the wall panel grout is poured and the ALC partition wall panels are cured. After the ALC partition wall panels are installed on site, only the pipes need to be connected and wired. However, during the process of pouring the wall panel grout, the locators may shift, deform or fall off under the impact of the grout, resulting in deviations in the position of the pipelines and easy misalignment of the pipelines. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a prefabricated ALC partition wall panel manufacturing mold. The impact of the slurry on the pipeline is weakened, the pipeline is not easy to shift or deform, and the accuracy of the pipeline position inside the ALC partition wall panel is guaranteed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold, comprising a support frame, the support frame comprising a base, a support fixed on the base, a guide frame fixed on the support, a plurality of parallel partition templates provided between the guide frame and the base, each partition template being equipped with a transverse guide component that moves along the length direction of the guide frame, a bottom template and two side templates being provided between any two adjacent partition templates, a plurality of limiting ropes being provided between the two side templates, and limiting rope positioning components being installed at both ends of each limiting rope.

[0007] The positioning component for the limiting rope includes a circular shell with an opening at one end. A fixing seat is installed on the opening of the circular shell. The bottom of the inner cavity of the circular shell is conical, and a rope hole is opened in the middle of the bottom of the inner cavity of the circular shell. A limiting seat is provided inside the circular shell. Three spheres are provided between the limiting seat and the bottom of the inner cavity of the circular shell. An elastic element is provided between the limiting seat and the fixing seat.

[0008] One end of the limiting rope passes through the rope hole of one of the limiting rope positioning components and is then inserted between the three spheres, which clamp the limiting rope.

[0009] As a preferred embodiment of the present invention, the positioning member of the limiting rope further includes an elastic conical tube located at the bottom of the inner cavity of the circular shell, and the three spheres are in contact with the inner wall of the elastic conical tube.

[0010] As a preferred embodiment of the present invention, the limiting seat is provided with three limiting slots at equal angles around the axis of the circular shell at the position corresponding to the bottom of the inner cavity of the circular shell, and each limiting slot is provided with a sphere.

[0011] The ball inside the limiting slot can move radially along the circular shell.

[0012] As a preferred embodiment of the present invention, it further includes a rotating head, wherein a through hole is provided on the rotating head and coincides with its axis, a rotatable tube is installed in the through hole, a plurality of cutting teeth are installed on the outer periphery of the rotating head, and one end of the rotating head and one end of the flexible shaft are detachably connected.

[0013] One end of the limiting rope is detachably connected to the tube.

[0014] As a preferred embodiment of the present invention, a plurality of elastic plates are fixed at equal angles around the axis of the rotating head near the flexible shaft on the outer periphery of the rotating head.

[0015] As a preferred embodiment of the present invention, an electric heating element is installed on the rotating head, and a conductive ring is installed on the flexible shaft at a position away from the rotating head, wherein the conductive ring and the electric heating element are electrically connected.

[0016] As a preferred embodiment of the present invention, the flexible shaft is fixed with an elastic annular protrusion at a position away from the rotating head.

[0017] As a preferred embodiment of the present invention, the support is equipped with a shielding member for shielding the guide frame.

[0018] As a preferred embodiment of the present invention, it further includes a label plate, wherein a plurality of label grooves are equally spaced along one length edge of the label plate.

[0019] As a preferred embodiment of the present invention, it also includes a limiting component, which is a bolt or a fixing rope, and the two farthest separating templates are detachably connected by the limiting component.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. The prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold of the present invention allows the pipeline to be pre-embedded in the ALC partition wall panel. The limiting rope transforms the pipeline from discrete point control in the prior art to continuous linear control. The impact of the slurry on the pipeline is evenly dispersed by the tension of the limiting rope, making the pipeline less prone to displacement and deformation, thus ensuring the accuracy of the pipeline position.

[0021] 2. In the assembly-type pre-embedded pipeline ALC partition wall panel manufacturing mold of the present invention, when the pipeline is impacted by the slurry, the pipeline causes the limiting rope to bend. The three balls inside the limiting rope positioning component squeeze the elastic cone tube, and the length of the limiting rope between the two limiting rope positioning components increases. The limiting rope reduces the impact on the pipeline. When the impact disappears, the elastic cone tube restores the limiting rope to a taut state, preventing the pipeline from shifting or being damaged.

[0022] 3. The prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold of the present invention cuts new pipeline holes between two operating slots, ensuring the flexibility of subsequent wiring, without damaging the integrity of the ALC partition wall panel, ensuring the mechanical properties of the ALC partition wall panel, avoiding cracking of the ALC partition wall panel surface, and reducing the wear and tear of the ALC partition wall panel.

[0023] 4. The assembly-type pre-embedded pipeline ALC partition wall panel manufacturing mold of the present invention uses an elastic sheet to bond vitrified polystyrene debris, forming a solid protective layer on the inner wall of the pipeline hole, preventing debris from falling off or collapsing on the inner wall of the pipeline hole, and reducing the frictional resistance when inserting pipelines into the pipeline hole.

Detailed Implementation

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Example 1 Please see Figures 1-6 This embodiment discloses a prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold, including a support frame 1. The support frame 1 includes a base 101, a support 102 fixed on the base 101, and a guide frame 4 fixed on the support 102. The guide frame 4 is located above the base 101 and is horizontally arranged. Several parallel partition templates 2 are provided between the guide frame 4 and the base 101. Each partition template 2 is equipped with a transverse guide 201 that moves along the length direction of the guide frame 4. Between any two adjacent partition templates 2, there is a bottom template 10 and two side templates 9. Several limiting ropes 8 are provided between the two side templates 9. Each limiting rope 8 has a limiting rope positioning component 6 installed at both ends.

[0028] The limiting rope positioning component 6 includes a circular shell 601 with one end open. A fixing seat 606 is installed on the opening of the circular shell 601. The bottom of the inner cavity of the circular shell 601 is conical, and a rope hole is opened in the middle of the bottom of the inner cavity of the circular shell 601. A limiting seat 604 is provided inside the circular shell 601. Three balls 603 are provided between the limiting seat 604 and the bottom of the inner cavity of the circular shell 601. An elastic element 605 is provided between the limiting seat 604 and the fixing seat 606. The elastic element 605 and the three balls 603 are all located inside the circular shell 601. The elastic element 605 is a spring or an elastic sheet.

[0029] One end of the limiting rope 8 passes through the rope hole of one of the limiting rope positioning parts 6 and is then inserted between the three balls 603. The three balls 603 clamp the limiting rope 8. The limiting seat 604 and the elastic member 605 make the ends of the three balls 603 and the limiting rope 8 form a self-locking structure at the bottom of the inner cavity of the circular shell 601. The limiting rope positioning part 6 makes it easy to install the limiting rope 8 between the two side templates 9.

[0030] The working process and principle of this embodiment are as follows: Workers cleaned the surface of the bottom formwork 10, the partition formwork 2, and the side formwork 9 of any remaining slurry and rust, ensuring that there were no adhering substances on the bottom formwork 10, the partition formwork 2, and the side formwork 9.

[0031] Workers place a bottom template 10 and two side templates 9 between any two adjacent partition templates 2. The bottom template 10 is placed horizontally on the base 101, with one end of the bottom template 10 abutting against the bottom end of the side template 9. Several limiting rope positioning pieces 6 are installed vertically on each side template 9. Several limiting ropes 8 are set vertically between two side templates 9. The ends of the limiting ropes 8 are connected to the side templates 9 through the limiting rope positioning pieces 6. Workers keep the limiting ropes 8 taut and use hemp rope or wire to fix the pipeline to the limiting ropes 8. The bottom template 10, the two adjacent partition templates 2, and the two side templates 9 form a pouring trough. A release agent is applied to the inner wall of the pouring trough.

[0032] Workers pour the mixed concrete slurry into each pouring trench in stages, with each pour being 20.0cm-50.0cm thick. This avoids excessive thickness at once, which could lead to slurry segregation or uneven stress on the molds. After the slurry reaches the set height, workers use an immersion vibrator to compact it. Then, workers scrape and level the surface of the slurry. After the slurry has been left to cure in the pouring trench for the set time, workers remove the partition formwork 2 and side formwork 9 in sequence. Using hoisting equipment or a load-bearing vehicle, the ALC partition wall panels are moved to the designated area.

[0033] The pipeline is pre-embedded in the ALC partition wall panel. The limiting rope 8 transforms the pipeline from discrete point control in the existing technology to continuous linear control. The impact of the slurry on the pipeline is evenly dispersed by the tension of the limiting rope, making the pipeline less prone to displacement and deformation, thus ensuring the accuracy of the pipeline position.

[0034] The prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold is easy to modify on existing molds, without the need for drilling or welding of fixing bases, which simplifies mold design and maintenance costs and improves the versatility of the mold.

[0035] Furthermore, the transverse guide 201 is a connecting plate with a sliding hole, through which the guide frame 4 passes and the connecting plate can slide along the guide frame 4; or the transverse guide 201 is a guide wheel, which is fixedly installed on the partition template 2 and can move along the length of the guide frame 4.

[0036] Furthermore, the partition template 2 and the side template 9 are detachably connected by snaps or locks, or the side template 9 and the bottom template 10 are detachably connected by snaps or locks.

[0037] Furthermore, the prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold also includes an identification plate 7. A number of identification grooves are equally spaced along the length of the identification plate 7. The identification grooves on the identification plate 7 facilitate the determination of the position of the limiting rope positioning piece 6 on the side template 9, so that each limiting rope 8 in the pouring groove is parallel to each other.

[0038] Furthermore, the cross-sectional area of ​​the end of the limiting rope 8 gradually increases in the direction away from the limiting rope 8, and the fixing seat 606 is bonded or magnetically attached to the side template 9.

[0039] Preferably, the limiting rope 8 is a steel wire rope or a fiber rope.

[0040] Preferably, the prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold also includes a limiting component 3, which is a bolt or a fixing rope. The two partition templates 2 that are furthest apart are detachably connected by the limiting component 3.

[0041] Example 2 like Figure 5 and Figure 6 As shown, this embodiment discloses a prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold, whose structure is roughly the same as that of Embodiment 1. The difference is that the limiting rope positioning component 6 in this embodiment also includes an elastic cone tube 602 located at the bottom of the inner cavity of the circular shell 601, and the three spheres 603 are in contact with the inner wall of the elastic cone tube 602.

[0042] The working process and principle of this embodiment are as follows: When the pipeline is impacted by the slurry, the pipeline causes the limiting rope 8 to bend. The three balls 603 inside the limiting rope positioning piece 6 squeeze the elastic cone tube 602, and the length of the limiting rope 8 between the two limiting rope positioning pieces 6 increases. The limiting rope 8 reduces the impact on the pipeline. When the impact disappears, the elastic cone tube 602 restores the limiting rope 8 to a taut state, preventing the pipeline from shifting or being damaged, and keeping the thickness between the pipeline and the surface of the ALC partition wall within the set range, thus ensuring the strength of the ALC partition wall.

[0043] Preferably, the elastic tapered tube 602 is made of elastic rubber or elastic silicone.

[0044] Example 3 like Figure 5 and Figure 6 As shown, this embodiment discloses a prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold, which is roughly the same as the structure of Embodiment 2. The difference is that in this embodiment, the limiting seat 604 is provided with three limiting slots at equal angles around the axis of the circular shell 601 at the bottom of the inner cavity of the circular shell 601, and each limiting slot is provided with a ball 603.

[0045] The ball 603 in the limiting slot can move radially along the circular shell 601.

[0046] The working process and principle of this embodiment are as follows: The limiting slot on the limiting seat 604 allows the ball 603 to move radially along the circular shell 601, ensuring the fixing effect of the three balls 603 inside the limiting rope positioning component 6 on the limiting rope 8.

[0047] Example 4 like Figures 8-10 As shown, this embodiment discloses a prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold, whose structure is roughly the same as that of Embodiment 1. The difference is that this embodiment also includes a rotating head 14. The rotating head 14 has a through hole that coincides with its axis. A through pipe 17 is installed in the through hole through a bearing or a rotating bushing. Several cutting teeth 11 are installed on the outer periphery of the rotating head 14. One end of the rotating head 14 and one end of the flexible shaft 13 are connected by a pin or nut.

[0048] One end of the limiting rope 8 and the tube 17 are connected by a buckle or glue.

[0049] Furthermore, the limiting rope 8 is coated with a release agent or wrapped with wax paper.

[0050] The working process and principle of this embodiment are as follows: In existing technologies, before ALC partition panels are produced in the factory, the pipelines and terminals are determined in the mold. If the design is changed later, or the pipeline routing is optimized on site, or new terminal points are added, the prefabricated ALC partition panels cannot be adapted and need to be reproduced, resulting in material waste and construction delays.

[0051] Workers chisel two operating grooves at the locations where new pipelines need to be added to the ALC partition wall panel, exposing the same limiting rope 8 inside the ALC partition wall panel. The limiting rope 8 is then cut open within the operating grooves. One end of the limiting rope 8 is connected to the through-pipe 17 on the rotating head 14. The worker continuously pulls the other end of the limiting rope 8, causing an external drive device to rotate the flexible shaft 13. The flexible shaft 13 causes the cutting teeth 11 on the rotating head 14 to cut along the length of the limiting rope 8 into the interior of the ALC partition wall panel, creating a new pipeline hole between the two operating grooves. This ensures flexibility for later wiring, prevents damage to the integrity of the ALC partition wall panel, maintains its mechanical properties, avoids cracking of the ALC partition wall surface, and reduces wear and tear.

[0052] Furthermore, the external drive device is a common electric drill in the prior art, and the end of the flexible shaft 13 away from the rotating head 14 is mounted on the chuck of the electric drill.

[0053] Furthermore, the distance between two adjacent limiting ropes 8 inside the ALC partition wall is 80.0mm-150.0mm.

[0054] Furthermore, the terminals include, but are not limited to, distribution boxes, low-voltage boxes, power sockets, network cable sockets, faucets, and gas connectors, and are attached or magnetically attached to the side template 9.

[0055] Example 5 like Figures 8-10 As shown, this embodiment discloses a prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold, which is roughly the same as the structure of embodiment four. The difference is that in this embodiment, a number of elastic plates 12 are fixed at equal angles around the axis of the rotating head 14 near the flexible shaft 13 on the outer periphery of the rotating head 14. The length direction of the elastic plates 12 is parallel to the axis of the circular shell 601.

[0056] The working process and principle of this embodiment are as follows: The elastic sheet 12 grinds the newly opened pipe holes in the ALC partition wall to reduce wear when the pipes pass through the pipe holes.

[0057] Example 6 like Figure 8 and Figure 9As shown, this embodiment discloses a prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold, whose structure is roughly the same as that of embodiment five. The difference is that in this embodiment, an electric heating element 15 is installed on the rotating head 14, and a conductive ring 16 is installed on the flexible shaft 13 away from the rotating head 14. The electric heating element 15 is electrically connected to an external power source through the conductive ring 16. The electric heating element 15 is an electric heating wire or an electric heating plate.

[0058] Furthermore, the slurry of the ALC partition board contains polystyrene foam particles with a diameter of 1.0mm-5.0mm, and the volume ratio of the polystyrene foam particles to the slurry is 1.0:3.0-10.0.

[0059] Furthermore, the cutting teeth 11, the rotating head 14, and the elastic plate 12 are all made of metal.

[0060] The working process and principle of this embodiment are as follows: The electric heating element 15 heats the cutting teeth 11, the elastic sheet 12, and the rotating head 14, maintaining the temperature of the rotating head 14 at 80℃-105℃. The rotating head 14 is pulled by the limiting rope 8, and the cutting teeth 11 on the rotating head 14 cut inside the ALC partition wall. The polystyrene foam particles in the cut debris are vitrified after being heated. The elastic sheet 12 makes the vitrified polystyrene adhere to the debris, forming a strong protective layer on the inner wall of the pipeline hole, preventing the inner wall of the pipeline hole from falling off or collapsing, and reducing the frictional resistance when inserting pipelines into the pipeline hole. The opening of new pipeline holes in the ALC partition wall has little impact on the ALC partition wall's compressive and impact resistance.

[0061] Example 7 like Figure 10 As shown, this embodiment discloses a prefabricated pre-embedded pipeline ALC partition wall panel manufacturing mold, whose structure is roughly the same as that of embodiment four. The difference is that in this embodiment, the flexible shaft 13 is fixed with an elastic annular protrusion 18 at a position away from the rotating head 14.

[0062] The working process and principle of this embodiment are as follows: The flexible shaft 13 causes the cutting teeth 11 on the rotating head 14 to cut the interior of the ALC partition wall along the length of the limiting rope 8. After forming a new pipeline hole between the two operating slots, the worker removes the rotating head 14 from one of the operating slots. The worker adds liquid resin to the pipeline hole near the annular protrusion 18. The worker pulls the flexible shaft 13, and the annular protrusion 18 on the flexible shaft 13 enters the pipeline hole. The annular protrusion 18 makes the resin evenly coated on the inner wall of the pipeline hole. After the resin coated on the inner wall of the pipeline hole hardens, the hardened resin makes the inner wall of the pipeline hole smooth, reducing the frictional resistance when the pipeline is inserted later.

[0063] Example 8 like Figure 1 and Figure 2 As shown, this embodiment discloses a prefabricated pre-embedded pipeline ALC partition wall manufacturing mold, which is roughly the same as the structure of Embodiment 1. The difference is that in this embodiment, a shielding member 5 of the shielding guide frame 4 is installed on the support 102 to prevent the slurry from dripping onto the guide frame 4 during the pouring process.

[0064] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
