Abstract
Description
Technical Field
[0001] This invention relates to the field of prefabricated wall panel production technology, and in particular to a production mold for prefabricated insulated sandwich wall panels. Background Technology
[0002] As the construction industry gradually moves towards industrialization and energy conservation, prefabricated sandwich insulated walls are increasingly being used in construction projects due to their advantages such as rapid construction, high cost-effectiveness, and environmental friendliness.
[0003] In the existing technology, the production mold for prefabricated insulated sandwich wall panels first inserts a steel frame formed by connecting horizontal and vertical steel bars, then pours concrete slurry to form the outer wall of the sandwich wall panel. After that, an insulation layer composed of multiple insulation boards is placed on the surface of the concrete slurry. Then, a steel frame formed by connecting horizontal and vertical steel bars is placed on top of the insulation layer, and finally, concrete slurry is poured to form the inner wall of the sandwich wall panel.
[0004] When using the above method to manufacture precast insulated sandwich wall panels, two concrete slurry pours are required, and a steel reinforcement frame needs to be placed before pouring, which reduces the production efficiency of precast sandwich wall panels. Furthermore, to reinforce the connection between the inner and outer walls, metal insulation connectors need to be placed in the mold. These connectors extend along the height of the mold and penetrate the insulation layer, causing damage to the insulation board. In the formed sandwich wall panel, the two ends of the insulation connectors are located in the inner and outer walls respectively, allowing heat transfer between the inner and outer walls through the connectors, thus reducing the thermal insulation capacity of the precast insulated sandwich wall panel. In addition, the horizontal and vertical steel reinforcements in the steel reinforcement frame are usually fixed with wire ties, which not only increases the workload and burden on workers, but also, due to the large number of connection points for the horizontal and vertical steel reinforcements, further reduces construction efficiency by requiring the tying of wires at each connection point.
[0005] Therefore, it is necessary to improve the production molds for prefabricated insulated sandwich wall panels in the existing technology. Summary of the Invention
[0006] The purpose of this invention is to overcome the defects in the existing technology and provide a production mold for prefabricated insulated sandwich wall panels that improves production efficiency, reduces the burden on workers, and enhances the thermal insulation capacity of products.

The casting channels are used to inject polyurethane, and the connecting side template and the separation side template, which are directly opposite to the separation side template, are used to cover the two ends of the casting channels, respectively.
[0013] Preferably, in order to further enhance the thermal insulation capacity and structural strength of the insulation component, the insulation unit includes a rectangular array of insulation mechanisms. The insulation mechanism includes two insulation plates facing each other with a gap. The adjacent surfaces of the two insulation plates are provided with parallel pouring channels.

[0015] Preferably, in order to enhance the structural strength of the insulation layer after the product is formed, the insulation unit further includes two reinforcing profiles extending parallel to the length direction of the casting channel and facing each other. The two reinforcing profiles are used to connect two adjacent insulation mechanisms to enclose and form a reinforcing channel communicating with the casting channel.
[0016] Preferably, in order to improve the product molding quality, the separation side template and the connection side template opposite to the separation side template are each provided with three pressure tubes for communicating with the inner page molding cavity, the reinforcement channel and the outer page molding cavity, respectively. Each of the three pressure tubes is provided with a pressure plug that moves along its own axis and is sealed together. The pressure plug is connected to a moving unit that drives its own movement.
[0017] Preferably, in order to facilitate the placement of the insulation components and the demolding of the product after the concrete slurry has cured and solidified, the three connecting side templates are rotatably connected to the bottom template and the rotation axis is parallel to its own axis.

[0020] In summary, compared with the prior art, the production mold of the prefabricated insulated sandwich wall panel of the present invention, by placing the insulation component on the bottom template and then adjusting the mold component to the second position by the adjustment component, allows concrete slurry to be poured into the outer and inner forming cavities simultaneously. After closing the separation side template, the concrete slurry solidifies and connects with the insulation component to form the product. Since the concrete slurry is poured and formed in one go, it is beneficial to improve construction efficiency. Attached Figure Description

Detailed Implementation
[0039] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.
[0040] like Figures 1-17 As shown, the production mold for the prefabricated insulated sandwich wall panel of the present invention is characterized by comprising:
[0041] A mold assembly, comprising a bottom mold plate 100, a top mold plate 200, a separation side mold plate 300 disposed around the bottom mold plate 100, and three connecting side mold plates 400, wherein the separation side mold plate 300, the three separation side mold plates 300, the top mold plate 200, and the bottom mold plate 100 are detachably enclosed to form a casting cavity;
[0042] A thermal insulation component is detachably disposed within the casting cavity to divide the casting cavity into an outer page forming cavity and an inner page forming cavity distributed along its own thickness direction. The thermal insulation component includes a thermal insulation unit and steel reinforcement frames 500 disposed on both sides of the thermal insulation unit.
[0043] An adjustment component is provided to control the movement of the mold assembly between a first position and a second position. In the first position, the mold assembly is horizontally positioned. In the second position, the separating side template 300 is positioned above the three connecting side templates 400.
[0044] When using the production mold of this invention, the mold assembly is first adjusted to the first position using the adjustment component, so that the mold assembly is set horizontally. Then, the separating side template 300 is separated from the three connecting side templates 400, the bottom template 100, and the top template 200, so that one side of the casting cavity is opened to facilitate the insertion of the heat insulation component. The heat insulation component divides the casting cavity into an inner page forming cavity and an outer page forming cavity. Then, the mold assembly is adjusted to the second position using the adjustment component. In the second position, the separating side template 300 is located above and to the side of the three connecting side templates 400, so that the mold assembly is tilted, and the openings of both the inner page forming cavity and the outer page forming cavity are tilted upwards to facilitate the insertion of the heat insulation component. Concrete slurry is poured into both the inner and outer page forming cavities simultaneously. After the concrete slurry fills the inner and outer page forming cavities, the separating side template 300 is connected to the top template 200, bottom template 100, and three connecting side templates 400. This prevents the concrete slurry from escaping while allowing it to solidify and form the inner and outer page walls respectively within the inner and outer page forming cavities. The inner and outer page walls are fixedly connected to both sides of the insulation unit, and the connection strength and structural strength of the inner and outer page walls are reinforced by the steel reinforcement frame 500, ultimately forming a prefabricated insulated sandwich wall panel product. Then, the separating side template 300 is removed for demolding, and the product can be taken out.
[0045] Compared to existing technologies, where the production of sandwich wall panels involves placing the inner wall steel frame 500, pouring concrete, then placing the insulation layer, and finally placing the outer wall steel frame 500 on the insulation layer and pouring concrete again, this invention first fixes the steel frame 500 on both sides of the insulation unit to form an insulation component. The insulation component is then placed on the bottom template 100 to divide the pouring cavity into an inner and outer forming cavity. The position of the mold component is adjusted by adjusting the components so that the inner and outer forming cavities are adjacent to the separation side template 300 and the exposed side is higher than the rest, allowing for simultaneous injection and filling of concrete slurry into both cavities. The separation side template 300 is connected to the bottom template 100, the top template 200, and three connecting side templates 400 to prevent concrete slurry overflow. After the concrete slurry solidifies, the product is obtained. Since the inner and outer walls are formed by injecting concrete slurry in one step, compared to the two-step injection of concrete slurry, the production mold of this invention can significantly improve the production efficiency of the product.
[0046] In this invention, the specific structure of the adjustment component is as follows: Figure 5 and Figure 6As shown, the adjustment assembly is used to control the rotation of the mold assembly, thereby controlling the height position of the separation side template 300 and the tilt direction of the mold assembly. The adjustment assembly includes a base 150, an adjustment plate 130 and a horizontal shaft 160 are arranged above the base 150. The two ends of the horizontal shaft 160 are fixedly connected to the base 150 through support rods 161. The horizontal shaft 160 extends along the length direction parallel to the separation side template 300. One end of the adjustment plate 130 is sealed and sleeved outside the horizontal shaft 160, so that the adjustment plate 130 can rotate around the axis of the horizontal shaft 160. The bottom template 100 is fixed above the adjustment plate 130 through a support column 101, so that the bottom template 100 can rotate synchronously with the adjustment plate 130. The base 150 is fixed to the ground, and a drive cylinder 170 is installed above the base 150. The axis of the drive cylinder 170 is parallel to the length direction of the separation side template 300. The cylinder barrel of the drive cylinder 170 is fixed to the base 150. The piston rod is hinged to the bottom of the adjustment plate 130 through the connecting rod 171. Thus, the drive cylinder 170 controls the extension and retraction of its piston rod, which acts on the adjustment plate 130 through the connecting rod 171, so that the adjustment plate 130 can rotate around the axis of the horizontal axis 160, thereby driving the bottom template 100 and the mold assembly to rotate, changing the tilt direction of the mold assembly, and thus controlling the mold assembly to switch and adjust between the first position and the second position.
[0047] A further improvement is that the steel reinforcement frame 500 includes a positioning frame 600 connected to the insulation unit, a transverse steel reinforcement 501 extending perpendicularly to the direction of extension, and a longitudinal steel reinforcement 502. The extension direction of the transverse steel reinforcement 501 is parallel to the length direction of the separation side template 300. The positioning frame 600 is provided with a transverse positioning hole 601 for the transverse steel reinforcement 501 to pass through in a sealed manner and a longitudinal positioning hole 602 for the longitudinal steel reinforcement 502 to pass through in a sealed manner.
[0048] Specifically, such as Figures 12-17 As shown, in the steel reinforcement frame 500, the positioning frame 600 is L-shaped. The positioning frame 600 is fixedly connected to the insulation unit by screws 603. The positioning frame 600 is provided with transverse positioning holes 601 and longitudinal positioning holes 602, which are respectively used for the transverse steel reinforcement 501 and the longitudinal steel reinforcement 502 to pass through in a sealed manner. In order to ensure the sealing performance, elastic sealing rings can also be set in the transverse positioning holes 601 and the longitudinal positioning holes 602. This allows the sealing rings to be sealed to the outer circumferential edge of the transverse steel reinforcement 501 and the longitudinal steel reinforcement 502 while providing sufficient damping force. This prevents the transverse steel reinforcement 501 and the longitudinal steel reinforcement 502 from axially shifting after they have passed through, without being affected by external forces. This ensures the structural stability of the steel reinforcement frame 500 before the concrete grout is poured.
[0049] A further improvement is that the insulation unit has pouring channels that are arranged side-by-side and connected along the length of the separation side template 300. The pouring channels are used to inject polyurethane. The connecting side template 400 and the separation side template 300, which are directly opposite to the separation side template 300, are respectively used to cover the two ends of the pouring channels. The insulation unit includes an insulation mechanism arranged in a rectangular array. The insulation mechanism includes two insulation plates 700 that are directly opposite each other and have a gap. Pouring channels 701 are arranged side-by-side on the adjacent surfaces of the two insulation plates 700. The pouring channels include the gap between the two insulation plates 700 and the pouring channels 701 of the two insulation plates 700.
[0050] Specifically, such as Figure 13 , Figure 16 and Figure 17 As shown, the insulation mechanism includes two insulation boards 700, which are positioned opposite each other with a gap between them. Each adjacent surface of the two insulation boards 700 has a casting groove 701 arranged parallel to the length of the separation side template 300. Both insulation boards 700 are square plate structures, and positioning holes 703 are provided at the four corners of adjacent surfaces. The positioning holes 703 are blind holes. The two insulation boards 700 are connected by four insertion rods 210, with a coaxial section at the center of each insertion rod 210. The two ends of the convex ring 211 of the center line and the plug rod 210 are respectively inserted into the positioning holes 703 on the two insulation boards 700. The two sides of the convex ring 211 are respectively attached to the adjacent surfaces of the two insulation boards 700, so that the two insulation boards 700 form a gap. At the same time, the pouring grooves 701 on the two insulation boards 700 are arranged opposite each other and connected through the gap to form part of the pouring channel. When multiple insulation mechanisms are spliced together in sequence along the length direction perpendicular to the separation side template 300, a long strip-shaped pouring channel is formed.
[0051] During the casting process, one end of the casting channel is first sealed by the connecting side template 400, which is directly opposite the separating side template 300. While pouring concrete slurry into the inner and outer page forming cavities, polyurethane is injected into the casting channel 701, and then the separating side template 300 is covered. After the concrete slurry solidifies and the polyurethane foams into a polyurethane insulation component, the polyurethane insulation component fills the gap between the two insulation boards 700 and the casting channel 701. That is, the polyurethane insulation component fills the casting channel and is fixedly connected to the two insulation boards 700. On the one hand, it strengthens the structural strength of the insulation layer in the formed product. On the other hand, it enhances the thermal insulation capacity of the prefabricated insulated sandwich wall panel by utilizing the thermal insulation properties of polyurethane.
[0052] A further improvement is that the internal space of the casting channel 701 includes a bottom space adjacent to its own bottom and a top space adjacent to its own top, wherein the width of the bottom space is greater than the width of the top space.
[0053] Specifically, in this invention, the cross-section of the casting channel 701 is T-shaped, making the width of the bottom space of the channel greater than the width of the opening space. This increases the contact area between the heat insulation component formed after polyurethane molding and the insulation board 700, strengthens the connection strength between the two, and prevents the heat insulation component from detaching from the insulation board 700, further enhancing the connection strength. Of course, the casting channel 701 can also be other shapes, such as a dovetail channel, a Y-shaped channel, or an L-shaped channel, which can also achieve the above-mentioned technical effects.
[0054] A further improvement is that the insulation unit also includes two reinforcing profiles 800 extending parallel to the length of the casting channel 701 and facing each other. The two reinforcing profiles 800 are used to connect two adjacent insulation mechanisms to enclose and form a reinforcing channel communicating with the casting channel.
[0055] like Figures 12-14 As shown, two reinforcing profiles 800 are symmetrically arranged along the height direction of the casting cavity. Both sides of the back of the two insulation boards 700 are provided with assembly grooves 702. The assembly grooves 702 are through grooves whose extension direction is consistent with the extension direction of the casting through groove 701. The assembly grooves 702 are L-shaped grooves. The two assembly grooves 702 on the same insulation board 700 are arranged back to back. The two sides of the reinforcing profile 800 are respectively adapted to the assembly grooves 702 on the two adjacent insulation boards 700, so that the reinforcing profile 800 can be stably connected with the two adjacent insulation boards 700. The two reinforcing profiles 800 facing each other and the four insulation boards 700 in the two adjacent insulation mechanisms form a reinforcing channel.
[0056] Thus, when polyurethane is injected into the pouring channel, it can simultaneously enter the reinforcement channel. The polyurethane fills the reinforcement channel and foams into a polyurethane insulation strip, which can be fixedly connected to the reinforcement profile 800. On the one hand, the reinforcement profile 800 enhances the structural strength of the entire insulation component, and on the other hand, the polyurethane insulation strip formed in the reinforcement channel further enhances the thermal insulation performance of the insulation component.
[0057] A further improvement is that the separation side template 300 and the connection side template 400 opposite to the separation side template 300 are each provided with three pressure tubes 900 for communicating with the inner page forming cavity, the reinforcement channel and the outer page forming cavity respectively. Each of the three pressure tubes 900 is provided with a pressure plug 110 that moves along its own axis and is sealed to it. The pressure plug 110 is connected to a moving unit 120 that drives its own movement.
[0058] like Figure 7 , Figure 8 , Figure 10 and Figure 11As shown, three pressure pipes 900 are provided on both the separation side template 300 and the connection side template 400. Each of the three pressure pipes 900 is sealed with a pressure plug 110 that slides with it. The moving unit 120 is a moving oil cylinder, whose cylinder is fixed on the separation side template 300 (or the connection side template 400). The piston rod is fixedly connected to the pressure plug 110 through the connecting frame 121.
[0059] During production, the mold assembly is adjusted to the second position, with the height of the connecting side template 400 lower than that of the separating side template 300 and the other two connecting side templates 400. The moving cylinder controls the pressure plug 110 to move away from the pouring cavity via the connecting frame 121. This allows space to be reserved within the three pressure pipes 900 on the connecting side template 400, facilitating the entry of some concrete slurry and polyurethane into the three pressure pipes 900 through the inner page forming cavity, outer page forming cavity, and reinforcing channel during pouring. Since the mold assembly is tilted at this time, some air may remain at the top of the inner page forming cavity, outer page forming cavity, reinforcing channel, and pouring channel 701. The separating side template 300 is then closed, allowing the separating side template 300 to... A certain gap is formed between the top template 200 and the two connecting side templates 400. Due to their own viscosity, the concrete slurry and polyurethane are prevented from overflowing from the gap, while the residual air can be easily discharged through the gap. The moving oil cylinder controls the pressure plug 110 to move closer to the pouring cavity through the connecting frame 121. Thus, after the concrete slurry and polyurethane are pressurized, they are concentrated and filled into the inner page forming cavity, the outer page forming cavity, the reinforcement channel, and the pouring channel, respectively. The residual air is discharged from the gap between the separating side template 300 and the top template 200 and the two connecting side templates 400. In this way, the forming quality of the inner page wall, the outer page wall and the insulation layer in the prefabricated insulated sandwich wall panel is improved, thereby improving the forming quality of the prefabricated insulated sandwich wall panel.
[0060] A further improvement is that the three connecting side templates 400 are rotatably connected to the bottom template 100 and their rotation axes are parallel to their own axes. The top template 200 includes three sub-templates 201 that are rotatably connected to the three connecting side templates 400 respectively. Each of the three sub-templates 201 is provided with a first positioning sleeve 202. The separating side template 300 is provided with a second positioning sleeve 302. The first positioning sleeve 202 and the second positioning sleeve 302 are connected by a threaded locking rod 180 and a threaded sleeve 190.
[0061] Specifically, the top template 200 is composed of three sub-templates 201. The three sub-templates 201 are rotatably connected to the top of the three connecting side templates 400, and the rotation axis is parallel to the length direction of the corresponding connecting side template 400. Each sub-template 201 is provided with two first positioning sleeves 202, while the top of the separating side template 300 is provided with two second positioning sleeves 302. Locking rods 180 are sealed inside the first positioning sleeves 202 and the second positioning sleeves 302. One end of the two locking rods 180 is integrally connected to form a U-shaped structure, and the other end is threadedly connected to a screw sleeve 190 to detachably connect the separating side template 300 to the top plate 200.
[0062] After casting, the side template 300 and the top template 200 are separated. Then, each of the sub-templates 201 is operated in sequence to separate the sub-templates 201 from the inner wall of the product one by one. In this way, by separating the side template 300 and the sub-templates 201 from the surface of the formed product, the contact area between the product and the mold components is gradually reduced, making it easier to demold and remove the product.
[0063] For the steel reinforcement frame 500 located above the insulation unit in the insulation component, the longitudinal steel bars 502 of the steel reinforcement frame 500 penetrate the separation side template 300 and the connecting side template 400 directly opposite the separation side template 300. In order to avoid the separation side template 300 being lost and to facilitate the quick assembly of the separation side template 300 and the top template 200, the separation side template 300 slides on the adjusting plate 130 along its own thickness direction. After forming, the above-mentioned longitudinal steel bars 502 penetrate the formed inner wall to ensure the bonding strength between the precast sandwich wall panel and the poured concrete during on-site construction.
[0064] Specifically, a sliding sleeve 301 is provided at the bottom of the separating side formwork 300, and a sliding rail 131 extending along the length of the longitudinal steel bar 502 is provided on the adjusting plate 130. The sliding sleeve 301 and the sliding rail 131 are slidably connected, thereby realizing the sliding connection between the separating side formwork 300 and the adjusting plate 130. After the insulation component is placed between the bottom formwork 100 and the three connecting side formworks 400, the separating side formwork 300 is slid, so that the separating side formwork 300 can be quickly fitted over the longitudinal steel bar 502 of the upper steel bar frame 500.
[0065] A further improvement is that the mold assembly further includes a mold support unit 140, which includes a mold support column 141 extending along the height direction of the casting cavity and a lifting unit 142 for driving the mold support column 141 to move along its own axial direction. The mold support column 141 seals through the insulation assembly and the bottom template 100 and its top is used for a sealed connection with the top template 200.
[0066] Specifically, such as Figures 4-6As shown, both the bottom template 100 and the insulation board 700 are provided with through holes for the formwork support column 141 to pass through. The lifting unit 142 is a lifting cylinder, whose cylinder is fixedly connected to the adjusting plate 130. The piston rod is fixedly connected to the plate 143 located below the bottom template 100. The top surface of the plate 143 is fixedly connected to the formwork support column 141. During pouring, the top of the formwork support column 141 is in contact with the bottom surface of the top template 200. In this way, multiple formwork support through holes are formed on the precast insulated sandwich wall panel. The formwork support through holes extend along the thickness direction of the precast insulated sandwich wall panel, which facilitates assembly and connection during on-site construction.
[0067] It should be noted that after casting, the support column 141 can be lowered by the lifting cylinder to detach from the product, and the separation side template 300 is separated from the top template 200. Then, the three sub-templates 201 are rotated outward to detach from the product. Then, the two connecting side templates 400 adjacent to the two ends of the separation side template 300 are rotated so that the two connecting side templates 400 are detached from the product. Then, the product is moved in a direction perpendicular to the separation side template 300 so that the product is detached from the remaining connecting side template 400 and the bottom template 100. The formed product can then be taken out.
