Description

Technical Field

[0001] The present application relates to the technical field of prefabricated component production, and in particular to a side mold structure. Background Art

[0002] At present, prefabricated plate components (including prefabricated floor slabs, prefabricated wall panels, prefabricated cantilever panels, reinforced prefabricated panels, prefabricated composite panels, etc.) are widely used in prefabricated building projects. In order to strengthen the connection between prefabricated plate components and other building parts, reinforced prefabricated panels are generally used. Reinforced prefabricated panels refer to prefabricated panels with steel grids exposed outside the panels. By pouring concrete at the exposed steel bars of the prefabricated panels, the prefabricated panels are connected to other building parts. The side molds used in the production of reinforced prefabricated panels are currently customized. The steel bar perforations or notches on the side molds are adapted to the spacing and diameter of the exposed steel bars. When the parameters such as the spacing and diameter of the exposed steel bars are adjusted, the original side molds cannot be adapted and the side molds need to be remade. This results in low versatility of such side molds, increased resource consumption, reduced production efficiency, and increased production costs of prefabricated panels.

[0003] Therefore, the market is in urgent need of a highly versatile side mold solution. Utility Model Content

[0004] To address the aforementioned issues, the present application provides a side mold structure with an ingenious design and simple structure. By providing a pressing member to press down the top mold body, the present application alleviates the problem of using a magnetic box to press down the top mold body, which would result in excessive use of the magnetic box, thereby saving the use of the magnetic box and reducing production costs. Furthermore, the threaded connection between the pressing member and the guide pin not only ensures the stability of the connection between the two, but also facilitates their separation. The technical solutions adopted by the present application are as follows:

[0005] A side mold structure, comprising:

[0006] A top mold body, wherein the top mold body is provided with a guide hole; a bottom mold body, wherein a side of the bottom mold body close to the top mold body is provided with a mounting groove corresponding to the position of the guide hole, and a guide pin is installed in the mounting groove; sealing strips are respectively installed on both sides adjacent to the top mold body and the bottom mold body;

[0007] The assembly state of the top mold body and the bottom mold body is as follows: the guide pin is passed through the guide hole and exposed outside the guide hole, the exposed end of the guide pin is screwed to a lower pressure piece with an internal thread, and the lower pressure piece is used to press the top mold body; the sealing strip on the top mold body and the sealing strip on the bottom mold body are squeezed against each other.

[0008] By providing a pressing member to press down the top mold body, the pressing member is used to reduce the use of magnetic boxes, which would otherwise result in excessive magnetic boxes being used. This saves on magnetic boxes and reduces production costs. Furthermore, the threaded connection between the pressing member and the guide pin not only ensures a stable connection between the two, but also facilitates separation.

[0009] In some embodiments, the side mold structure also includes a pressure plate; the assembly state of the top mold body and the bottom mold body is: the guide pin is sequentially passed through the guide hole and the pressure plate, and the pressure plate is padded between the top mold body and the lower pressure piece.

[0010] By setting up the pressure plate, the pressure plate acts as a gasket, increasing the force-bearing area of the top mold body, improving the extrusion effect of the sealing strip on the top mold body and the sealing strip on the bottom mold body, and reducing the risk of leakage of the side mold structure.

[0011] In some embodiments, the top mold body and the bottom mold body are both hollow structures and both ends of the structures are sealed by sealing plates.

[0012] By setting both the top mold body and the bottom mold body as hollow structures, the materials used in the production of the top mold body and the bottom mold body can be saved, the weight of the top mold body and the bottom mold body can be reduced, and it is easy to carry and use; in addition, using sealing plates to seal the two ends of the top mold body and the bottom mold body can prevent slurry from entering the top mold body and the bottom mold body when casting plate-type components.

[0013] In some embodiments, the side mold structure further includes a sleeve, which is disposed in the guide hole of the top mold body to isolate the guide hole of the top mold body from the hollow space of the top mold body.

[0014] By providing the sleeve, it is possible to prevent slurry from entering the hollow space of the top mold body along the guide hole when casting plate-like components, thereby affecting the cleanliness and service life of the top mold body.

[0015] In some embodiments, the guide pin is provided with a table; the assembled state of the top mold body and the bottom mold body is: the table is located between the top mold body and the bottom mold body, and the table abuts against the side of the top mold body close to the bottom mold body.

[0016] By setting a table top and making it abut against the top mold body, the distance between the top mold body and the bottom mold body can be controlled, thereby achieving control of the overall thickness of the side mold structure and then adapting it to the thickness of the plate component.

[0017] In some embodiments, the guide pin includes a large diameter section, a gradual section, and a small diameter section connected in sequence, and the large diameter section is provided with an external thread adapted to the pressing member.

[0018] By providing a large diameter section, a gradual change section, and a small diameter section connected in sequence, the gradual change section and the small diameter section serve as guides, making it easier for one end of the guide pin to pass through the guide hole in the top mold body, thereby reducing the difficulty of aligning the guide pin with the guide hole. Furthermore, this also reduces the difficulty of aligning the lower pressure piece with the guide pin, making it easier to screw the lower pressure piece onto one end of the guide pin.

[0019] In some embodiments, the side mold structure also includes a support seat, which is suitable for being installed in the mounting groove and exposed in the mounting groove, and the exposed end face of the support seat is suitable for abutting the side of the top mold body close to the bottom mold body, and the support seat is provided with a slot, and the support seat is used to control the vertical distance between the top mold body and the bottom mold body; the bottom end of the guide pin is suitable for being magnetically attracted to the slot; and a plurality of protrusions or grooves are provided on the side of the top mold body close to the prefabricated panel to form a rough surface.

[0020] By providing a rough surface, an uneven structure (rough surface) can be formed on the side of the precast panel after the side mold is removed, thereby improving the adhesion between the precast panel and other parts of the building. It is understandable that due to the provision of the rough surface, in order to ensure the integrity of the side of the precast panel when removing the top mold body, the top mold body cannot be moved along the thickness direction of the precast panel when removing it, but should be moved in a direction perpendicular to the thickness of the precast panel and away from the precast panel. This requires the guide pin to be removed before the top mold body is removed. The magnetic connection between the guide pin and the support seat can realize the rapid disassembly and assembly of the guide pin, which facilitates the disassembly efficiency of the top mold body.

[0021] In some embodiments, the pressing member is provided with a blind hole, and the blind hole is provided with an internal thread adapted to the exposed end of the guide pin.

[0022] By arranging the internal thread of the pressing member in the blind hole, the risk of slurry entering the screw hole when casting plate-like components can be reduced.

[0023] In some embodiments, the pressing member is in the shape of a regular hexagonal prism.

[0024] By setting the pressing member in the shape of a regular hexagonal prism, it is convenient to use a commonly used hexagonal wrench or hexagonal socket to screw the pressing member, thereby improving the compatibility of the pressing member with commonly used assembly and disassembly tools.

[0025] In some embodiments, the top mold body and the bottom mold body are both provided with a card slot, and the card slot notch on the top mold body is arranged opposite to the card slot notch on the bottom mold body, and the groove walls on both sides of the card slot are provided with a card protrusion; the sealing strip is provided with a card slot adapted to the card protrusion, and the sealing strip is carded in the card slot through the cooperation of the card slot and the card protrusion, and the sealing strip is partially exposed in the card slot.

[0026] In some embodiments, the sealing strip includes a soft strip portion and a hard strip portion, the snap-in groove is provided on the hard strip portion, the hard strip portion is snap-in to the snap-in groove through the cooperation between the snap-in groove and the snap-in protrusion, and the soft strip portion is exposed in the snap-in groove; when the top mold body and the bottom mold body are in an assembled state, the soft strip portion of the sealing strip on the top mold body and the soft strip portion of the sealing strip on the bottom mold body are squeezed against each other.

[0027] By setting up a soft rubber strip part and a hard rubber strip part, the soft rubber strip part is softer than the hard rubber strip part and has better filling performance, which is conducive to tightly wrapping around the outer periphery of the exposed steel bar and improving the sealing of the side of the prefabricated board. The hard rubber strip part is harder and stronger than the soft rubber strip part, which can provide strong support for the soft rubber strip part and ensure the ability of the sealing strip to recover from deformation. At the same time, the hard rubber strip part also plays a buffering role to prevent the direct action of the soft rubber strip part and the top mold body (or bottom mold body), thereby reducing the risk of damage to the soft rubber strip part.

[0028] In some embodiments, the sealing strip has a cavity filled with a foaming material.

[0029] By filling the cavity with foam material, the deformation recovery ability of the sealing strip can be improved, ensuring that the sealing strip can maintain its original shape after long-term use.

[0030] In some embodiments, the engaging protrusion is dovetail-shaped, and the engaging groove is a dovetail groove.

[0031] By designing the snap-fit protrusion into a dovetail shape and the snap-fit groove into a dovetail groove, the connection firmness between the sealing strip and the top mold body (or bottom mold body) can be improved, reducing the risk of the sealing strip returning to the snap-fit groove when squeezed by exposed steel bars, thereby improving the wrapping effect of the sealing strip on the exposed steel bars.

[0032] The side mold structure provided in this application has at least one of the following beneficial effects:

[0033] 1. The side mold structure provided in this application utilizes a downward pressure member to press down the top mold body, thereby alleviating the problem of using a magnetic box to press down the top mold body, which would result in excessive use of the magnetic box. This saves magnetic box usage and reduces production costs. Furthermore, the threaded connection between the downward pressure member and the guide pin not only ensures a stable connection between the two, but also facilitates separation.

[0034] 2. The present application provides a side mold structure, which, by setting a pressure plate, acts as a gasket, increases the force-bearing area of the top mold body, improves the extrusion effect of the sealing strip on the top mold body and the sealing strip on the bottom mold body, and reduces the risk of leakage of the side mold structure.

[0035] 3. The present application provides a side mold structure, which saves materials used in the production of the top mold body and the bottom mold body by setting both the top mold body and the bottom mold body to be hollow structures, reduces the self-weight of the top mold body and the bottom mold body, and facilitates transportation and use; in addition, by using sealing plates to seal the two ends of the top mold body and the bottom mold body, it is possible to prevent slurry from entering the top mold body and the bottom mold body when casting plate-type components.

[0036] 4. The side mold structure provided in the present application can prevent the slurry from entering the hollow space of the top mold body along the guide hole when casting plate-like components by setting a sleeve, thereby affecting the cleanliness and service life of the top mold body.

[0037] 5. The present application provides a side mold structure, which can control the distance between the top mold body and the bottom mold body by setting a table top and making the table top abut against the top mold body, thereby achieving control of the overall thickness of the side mold structure and then adapting it to the thickness of the plate-like components.

[0038] 6. This application provides a side mold structure that comprises a sequentially connected large-diameter section, a gradual-change section, and a small-diameter section. The gradual-change section and the small-diameter section serve as guides, facilitating the guide pin's end to pass through a guide hole in the top mold body, thereby simplifying the alignment of the guide pin with the hole. Furthermore, this also simplifies the alignment of the lower pressure piece with the guide pin, facilitating the threaded connection of the lower pressure piece to the guide pin's end.

[0039] 7. The present application provides a side mold structure that, by providing a rough surface, can form an uneven structure (rough surface) on the side of the prefabricated panel after the side mold is removed, thereby improving the adhesion between the prefabricated panel and other parts of the building. It is understandable that due to the provision of the rough surface, in order to ensure the integrity of the side of the prefabricated panel when removing the top mold body, the top mold body cannot be moved along the thickness direction of the prefabricated panel when removing it, but should be moved in a direction perpendicular to the thickness of the prefabricated panel and away from the prefabricated panel. This requires the removal of the guide pin before removing the top mold body. The magnetic connection between the guide pin and the support seat can realize the rapid disassembly and assembly of the guide pin, which facilitates the disassembly efficiency of the top mold body.

[0041] 9. The side mold structure provided in the present application, by setting the pressing piece into a regular hexagonal prism shape, can facilitate the use of a commonly used hexagonal wrench or hexagonal socket to screw the pressing piece, thereby improving the compatibility of the pressing piece with commonly used assembly and disassembly tools.

[0042] 10. The present application provides a side mold structure, which is provided with a soft rubber strip part and a hard rubber strip part. The soft rubber strip part is softer than the hard rubber strip part and has better filling performance, which is conducive to tightly wrapping around the outer periphery of the exposed steel bars, thereby improving the sealing of the side of the prefabricated panel. The hard rubber strip part is harder and stronger than the soft rubber strip part, which can provide strong support for the soft rubber strip part and ensure the ability of the sealing strip to recover from deformation. At the same time, the hard rubber strip part also plays a buffering role to prevent the soft rubber strip part from directly interacting with the top mold body (or bottom mold body), thereby reducing the risk of damage to the soft rubber strip part.

[0043] 11. The present application provides a side mold structure, which can improve the deformation recovery ability of the sealing strip by filling the cavity with foaming material, ensuring that the sealing strip can maintain its original shape after long-term use.

DETAILED DESCRIPTION

[0061] In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the specific implementation methods of the present application will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without inventive work.

[0062] To simplify the drawings, only the parts relevant to this application are schematically shown in each figure. They do not represent the actual structure of the product. In addition, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. In this document, "one" not only means "only one" but also "more than one."

[0063] It should be further understood that the term "and / or" used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0064] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0065] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0066] refer to Figure 1-Figure 5 The present application provides a side mold structure, including: a top mold body 1 and a bottom mold body 3. The top mold body 1 is provided with a guide hole 2. The bottom mold body 3 is provided with a mounting groove 4 corresponding to the position of the guide hole 2 on the side close to the top mold body 1, and a guide pin 5 is installed in the mounting groove 4; sealing strips 6 are respectively installed on the two adjacent sides of the top mold body 1 and the bottom mold body 3; the assembly state of the top mold body 1 and the bottom mold body 3: the guide pin 5 is passed through the guide hole 2 and exposed in the guide hole 2, the exposed end of the guide pin 5 is screwed to a lower pressure piece 7 with an internal thread, and the lower pressure piece 7 is used to press the top mold body 1; the sealing strip 6 on the top mold body 1 and the sealing strip 6 on the bottom mold body 3 squeeze each other. By mutually squeezing the sealing strip 6 installed on the top form body 1 and the sealing strip 6 installed on the bottom form body 3, the sealing strip 6 can be wrapped around the outer periphery of the exposed steel bars of the plate-like component to be cast, thereby preventing leakage of slurry from the side of the plate-like component when casting the plate-like component. In other words, it prevents the slurry (which can be concrete) from flowing out of the side formwork structure along the exposed steel bars of the plate-like component.

[0067] The installation process of the side mold structure of the present application is as follows: the bottom mold body 3 is pressed onto the mold platform for making plate-like components through a magnetic box, and then the steel grid of the plate-like components to be cast is placed on the sealing strip 6 of the bottom mold body 3, and then the top mold body 1 is placed on the bottom mold body 3 through the cooperation of the guide pin 5 and the guide hole 2, so that the sealing strip 6 on the top mold body 1 is pressed on the upper side of one end of the steel grid (exposed steel bars), and then the lower pressing piece 7 is screwed to the end of the guide pin 5 exposed in the guide hole 2, which helps the lower pressing piece 7 to press the top mold body 1 downward, so that the upper and lower sealing strips 6 are wrapped around the outer periphery of the exposed steel bars, and the assembly of the side mold structure is completed.

[0068] Specifically, the guide pin 5 can be screwed into the mounting groove 4, or can be glued into the mounting groove 4, or a combination of screwing and gluing. Regardless of the method used, as long as the guide pin 5 can be fixed in the mounting groove 4, this application does not impose any restrictions on the specific method of fixing the guide pin 5 in the mounting groove 4.

[0069] As can be understood, this side mold structure offers strong versatility and excellent sealing, improving side mold utilization and the production efficiency of precast panel components. By providing a hold-down member 7, which is used to press down the top mold body 1, the problem of using a magnetic box to press down the top mold body 1, which would result in excessive use of the magnetic box, is alleviated. This saves on magnetic boxes and reduces production costs. Furthermore, the threaded connection between the hold-down member 7 and the guide pin 5 not only ensures a stable connection, but also facilitates separation.

[0070] Specifically, the top mold body 1 and the bottom mold body 3 can be obtained by extrusion molding of aluminum, or by welding of patterned plates, or by extrusion molding of FRP glass fiber reinforced plastics, or by extrusion molding of materials such as polyurethane, or by casting. This application does not impose any restrictions on the specific manufacturing materials and processes of the top mold body 1 and the bottom mold body 3. Figure 1-Figure 5 Preferably, both the top mold body 1 and the bottom mold body 3 are hollow structures, and both ends are sealed by sealing plates (not shown). It can be understood that by setting both the top mold body 1 and the bottom mold body 3 as hollow structures, the material used in the production of the top mold body 1 and the bottom mold body 3 can be saved, the weight of the top mold body 1 and the bottom mold body 3 can be reduced, and the handling and use of the top mold body 1 and the bottom mold body 3 can be facilitated. In addition, using the sealing plates to seal the ends of the top mold body 1 and the bottom mold body 3 can prevent slurry from entering the top mold body 1 and the bottom mold body 3 when casting plate-like components.

[0071] It is worth noting that the reference Figure 1 、 Figure 2 、 Figure 5 In one embodiment, the side mold structure further includes a pressure plate 8. When the top mold body 1 and the bottom mold body 3 are assembled, the guide pin 5 is sequentially inserted into the guide hole 2 and the pressure plate 8. The pressure plate 8 is placed between the top mold body 1 and the lower pressure member 7. The provision of the pressure plate 8 acts as a gasket, increasing the load-bearing area of the top mold body 1, improving the compression effect between the sealing strip 6 on the top mold body 1 and the sealing strip 6 on the bottom mold body 3, and reducing the risk of slurry leakage in the side mold structure.

[0072] refer to Figure 2-Figure 4 In one embodiment, the side mold structure further includes a sleeve 9 disposed within the guide hole 2 of the top mold body 1 to isolate the guide hole 2 of the top mold body 1 from the hollow space of the top mold body 1. The provision of the sleeve 9 prevents slurry from flowing through the guide hole 2 into the hollow space of the top mold body 1 during casting of plate-like components, thereby preventing the cleanliness and service life of the top mold body 1 from being affected.

[0073] It is easy to understand that the reference Figure 3 、 Figure 4 、 Figure 6In one embodiment, the guide pin 5 is provided with a table 10; when the top mold body 1 and the bottom mold body 3 are assembled, the table 10 is located between the top mold body 1 and the bottom mold body 3, and the table 10 abuts the side of the top mold body 1 closest to the bottom mold body 3. By providing the table 10 and abutting the table 10 with the top mold body 1, the distance between the top mold body 1 and the bottom mold body 3 can be controlled, thereby achieving control over the overall thickness of the side mold structure and adapting it to the thickness of the plate-like component.

[0074] It is worth noting that the reference Figure 2-Figure 4 、 Figure 6 In one embodiment, the guide pin 5 includes a large diameter section 11, a gradual change section 12, and a small diameter section 13 connected in sequence, and the large diameter section 11 is provided with an external thread adapted to the push-down member 7. By providing the large diameter section 11, the gradual change section 12, and the small diameter section 13 connected in sequence, the gradual change section 12 and the small diameter section 13 play a guiding role, which facilitates one end of the guide pin 5 to pass through the guide hole 2 on the top mold body 1, thereby reducing the difficulty of aligning the guide pin 5 with the guide hole 2. In addition, the difficulty of aligning the push-down member 7 with the guide pin 5 can be reduced, thereby facilitating the screw connection of the push-down member 7 to one end of the guide pin 5. In other embodiments, the guide pin 5 can be a columnar structure with a uniform cross-section.

[0075] In one embodiment, the side mold structure further includes a support seat 17, which is suitable for being installed in the mounting groove 4 and exposed in the mounting groove 4. The exposed end surface of the support seat 17 is suitable for abutting against the side of the top mold body 1 close to the bottom mold body 3. The support seat 17 is provided with a slot (not shown in the figure). The support seat 17 is used to control the vertical distance between the top mold body 1 and the bottom mold body 3; the bottom end of the guide pin 5 is suitable for being magnetically attracted in the slot; a plurality of protrusions 18 or grooves 19 are provided on the side of the top mold body 1 close to the prefabricated plate (refer to FIG. Figure 11-13 ) to form a rough surface.

[0076] It is worth noting that by providing a rough surface, an uneven structure (rough surface) can be formed on the side of the prefabricated panel after the side mold structure is disassembled, thereby improving the adhesion between the prefabricated panel and other parts of the building. It is understandable that due to the provision of a rough surface, in order to ensure the integrity of the side of the prefabricated panel when removing the top mold body 1, the top mold body 1 cannot be moved along the thickness direction of the prefabricated panel when removing it, but should be moved in a direction perpendicular to the thickness of the prefabricated panel and away from the prefabricated panel. This requires that the guide pin 5 be removed before the top mold body 1 is removed, and the magnetic connection between the guide pin 5 and the support seat 17 can realize the rapid disassembly and assembly of the guide pin, thereby improving the disassembly efficiency of the top mold body 1.

[0077] In this embodiment, reference Figure 7 、 Figure 8The magnetic attraction between the guide pin 5 and the slot can be achieved by providing a magnetic base 22 between the two, for example, by installing the magnetic base 22 at the bottom end of the guide pin 5 body, or by installing the magnetic base 22 into the slot. Preferably, the magnetic base 22 is installed at the bottom end of the guide pin 5 body, as this solution is easier to implement than fixing the magnetic base 22 into the slot. Specifically, the magnetic base can be screwed to the guide pin 5 body or adhesively bonded to the guide pin 5 body.

[0078] In one embodiment, the hold-down member 7 is provided with a blind hole having an internal thread therein that mates with the exposed end of the guide pin 5. By placing the internal thread of the hold-down member 7 in the blind hole, the risk of slurry entering the screw hole during casting of plate-like components can be reduced. In other embodiments, the hold-down member 7 is provided with a through hole having an internal thread therein that mates with the exposed end of the guide pin 5.

[0079] refer to Figure 1 、 Figure 2 、 Figure 5 In one embodiment, the pressing member 7 is in the shape of a regular hexagonal prism. By setting the pressing member 7 in the shape of a regular hexagonal prism, it is easy to use a commonly used hexagonal wrench or hexagonal socket to screw the pressing member 7, thereby improving the compatibility of the pressing member 7 with commonly used assembly and disassembly tools.

[0080] refer to Figure 3 、 Figure 4 In one embodiment, both the top mold body 1 and the bottom mold body 3 are provided with a snap-in groove 14, and the notch of the snap-in groove 14 on the top mold body 1 is arranged opposite the notch of the snap-in groove 14 on the bottom mold body 3. Snap-in protrusions 15 are provided in the groove walls on both sides of the snap-in groove 14. The sealing strip 6 is provided with a snap-in groove 16 that matches the snap-in protrusions 15. The sealing strip 6 is snap-into the snap-in groove 14 through the engagement of the snap-in groove 16 with the snap-in protrusion 15, with a portion of the sealing strip 6 exposed outside the snap-in groove 14. It is easy to understand that the provision of the snap-in protrusions 15 and the snap-in groove 16 can enhance the connection strength between the sealing strip 6 and the top mold body 1 and the bottom mold body 3, thereby preventing the sealing strip 6 from separating from the top mold body 1 and the bottom mold body 3.

[0081] It is worth noting that the cross-sectional shape of the clamping protrusion 15 can be rectangular, arc-shaped, or dovetail-shaped. Figure 3 、 Figure 4Preferably, the engaging protrusion 15 is dovetail-shaped, and the engaging groove 16 is a dovetail groove. By designing the cross-section of the engaging protrusion 15 to be dovetail-shaped and the engaging groove 16 to be a dovetail groove, the connection between the sealing strip 6 and the top mold body 1 (or bottom mold body 3) can be strengthened, the risk of the sealing strip 6 retreating into the engaging groove 14 when squeezed by the exposed steel bars can be reduced, and the wrapping effect of the sealing strip 6 on the exposed steel bars can be improved. In other embodiments, only the engaging groove 14 can be provided without the engaging protrusion 15, and the slot size of the engaging groove 14 can be small while the size inside the engaging groove 14 is large, that is, the engaging groove 14 has a constricted structure, such as a dovetail groove structure.

[0082] refer to Figure 3 、 Figure 4 、 Figures 9-13 In one embodiment, the sealing strip 6 includes a soft strip portion 20 and a hard strip portion 21. The snap-in groove 16 is provided on the hard strip portion 21. The hard strip portion 21 is snap-fitted into the snap-in groove 14 through the cooperation of the snap-in groove 16 and the snap-in protrusion 15, and the soft strip portion 20 is exposed in the snap-in groove 14. When the top mold body 1 and the bottom mold body 3 are assembled, the soft strip portion 20 of the sealing strip 6 on the top mold body 1 and the soft strip portion 20 of the sealing strip 6 on the bottom mold body 3 are squeezed against each other.

[0083] It is easy to understand that by setting the soft rubber strip part 20 and the hard rubber strip part 21, the soft rubber strip part 20 is softer than the hard rubber strip part 21 and has better filling performance, which is conducive to tightly wrapping around the exposed steel bar periphery, thereby improving the sealing of the side of the prefabricated board, while the hard rubber strip part 21 is harder and stronger than the soft rubber strip part 20, which can provide strong support for the soft rubber strip part 20 and ensure the ability of the sealing strip 6 to recover from deformation. At the same time, the hard rubber strip part 21 also plays a buffering role to prevent the soft rubber strip part 20 from directly interacting with the top mold body 1 (or the bottom mold body 3), thereby reducing the risk of damage to the soft rubber strip part 20.

[0084] It is worth noting that the soft rubber strip portion 20 and the hard rubber strip portion 21 can be produced separately and then bonded or welded together to form the overall structure of the sealing strip 6. The sealing strip 6 can also be produced using a two-color extrusion process to form the soft rubber strip portion 20 and the hard rubber strip portion 21. It is easy to understand that producing the sealing strip 6 using a two-color extrusion process can improve the production efficiency of the sealing strip 6 and ensure the production quality of the sealing strip 6. Specifically, the soft rubber strip portion 20 can be a foamed rubber strip, such as an EPDM foamed (sponge) rubber strip, and the hard rubber strip portion 21 can be a hard rubber strip, such as an EPDM rubber strip.

[0085] refer to Figure 3 、 Figure 4 、 Figures 9-13In one embodiment, the sealing strip 6 has a cavity filled with a foam material (not shown). Filling the cavity with the foam material improves the deformation recovery ability of the sealing strip 6, ensuring that the sealing strip 6 can maintain its original shape after long-term use. It should be noted that the sealing strip 6 is more effective in recovering from deformation when the hardness of the foam material is less than that of the soft strip portion 20.

[0086] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be noted that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be considered as the scope of protection of the present application.
