Description

Technical Field

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

[0002] At present, prefabricated plate components (including prefabricated floor slabs, prefabricated wall panels, prefabricated cantilever slabs, prefabricated composite slabs, etc.) are widely used in prefabricated building projects. In order to strengthen the connection between prefabricated plate components and other parts of the building, reinforced prefabricated slabs are generally used. Reinforced prefabricated slabs refer to prefabricated slabs whose steel grid is exposed outside the slab. The prefabricated slabs are connected to other parts of the building by pouring concrete at the exposed steel bars of the prefabricated slabs. At present, the side molds used in the production of reinforced prefabricated slabs are all 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 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 slabs.

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

[0004] In order to solve the above problems, the present application provides a side mold structure for prefabricated plate components, which has an ingenious design and a simple structure. The side mold structure of the present application has strong versatility and good sealing, which improves the utilization rate of the side mold and the production efficiency of prefabricated plate components. At the same time, by setting a perforation on the guide pin, it is convenient to use the perforation to pull out the guide pin, thereby facilitating the separation of the top mold and the bottom film. In addition, by setting the sealing strips respectively clamped on the top mold body and the bottom mold body to the same specifications, the specifications and types of the sealing strips can be reduced, the versatility of the sealing strips can be enhanced, and the production cost of the sealing strips can be reduced. The technical solutions adopted in this application are as follows:

[0008] The guide pin is suitable for being inserted into the guide hole and its bottom end is magnetically attracted to the slot, and its top end is exposed from the guide hole. The top end of the guide pin is provided with a through hole arranged along its transverse direction, and the through hole is used to provide a force point for the disassembly of the guide pin. The guide pin is used to limit the relative horizontal displacement between the top mold body and the bottom mold body.

[0009] The side mold structure has strong versatility and good sealing performance, which improves the utilization rate of the side mold and the production efficiency of prefabricated plate components. At the same time, by setting a perforation on the guide pin, it is convenient to use the perforation to pull out the guide pin, thereby facilitating the separation of the top mold and the bottom mold. In addition, by setting the sealing strips respectively clamped on the top mold body and the bottom mold body to the same specifications, the specifications and types of the sealing strips can be reduced, the versatility of the sealing strips is enhanced, and the production cost of the sealing strips is reduced.

[0010] 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.

[0011] 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 and the dead weight of the top mold body and the bottom mold body can be reduced; in addition, by using sealing plates to seal the two ends of the top mold body and the bottom mold body, concrete can be prevented from entering the top mold body and the bottom mold body when casting plate-like components.

[0012] In some embodiments, a magnetic seat is provided at the bottom end of the guide pin, and the bottom end of the guide pin can be magnetically attracted to the slot through the magnetic seat.

[0013] The magnetic connection between the guide pin and the support seat can not only prevent the guide pin from falling out of the slot when the side mold structure vibrates, but also realize the quick disassembly and assembly of the guide pin and the support seat. Compared with fixing the magnetic seat to the slot, fixing the magnetic seat to the bottom end of the guide pin is easier to achieve.

[0014] In some embodiments, the support seat includes a threaded portion and a supporting portion, the threaded portion is connected to the bottom end of the supporting portion, the threaded portion is suitable for being threaded into the mounting groove, the supporting portion is exposed in the mounting groove, and the top and bottom ends of the supporting portion are respectively suitable for abutting against the adjacent two sides of the top mold body and the bottom mold body.

[0015] After the top mold body is pressed onto the bottom mold body, by enabling the top and bottom ends of the support part to respectively abut against the top mold body and the bottom mold body, on the one hand, 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 to the thickness of the plate-like components; on the other hand, the bottom end of the support part abuts against the bottom membrane body, which can share the pressure transmitted by the support part borne by the screw connection part, that is, the screw connection part and the bottom end of the support part jointly bear the pressure borne by the top end of the support part, thereby reducing the risk of damage to the part where the screw connection part is screwed to the mounting groove.

[0016] In some embodiments, the guide pin includes a large diameter section, a gradual change section, and a small diameter section connected in sequence, and the cross-sectional size of the large diameter section is adapted to both the guide hole and the slot.

[0017] By arranging the guide pin to consist of a large diameter section, a gradient section and a small diameter section connected in sequence, the gradient section and the small diameter section play a guiding role, which can facilitate the guide pin to pass through the guide hole on the top mold body, reduce the difficulty of the guide pin passing through the guide hole, and improve the efficiency of installing the top mold body on the bottom mold body.

[0018] 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 card-engaging protrusions; the sealing rubber strip includes a soft rubber strip part and a hard rubber strip part, and the hard rubber strip part is provided with a card slot matched with the card-engaging protrusion, and the hard rubber strip part is carded in the card slot through the cooperation of the card slot and the card protrusion, and the soft rubber strip part is exposed in the card slot, and the soft rubber strip part can be wrapped around the periphery of the exposed steel bar through the mutual extrusion of the upper and lower soft rubber strip parts.

[0019] By providing the snap-in protrusions and the snap-in grooves, the connection strength between the sealing strip and the top mold body and the bottom mold body can be enhanced to prevent the sealing strip from detaching from the top mold body and the bottom mold body; by providing the soft rubber strip part and the 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 and improving the sealing of the side of the plate-like components, while the hard rubber strip part is harder than the soft rubber strip part and can provide strong support for the soft rubber strip part to 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 the bottom mold body) and reduce the risk of damage to the soft rubber strip part.

[0020] In some embodiments, the sealing strip is made by a two-color extrusion process to form the soft strip portion and the hard strip portion.

[0021] The production efficiency of the sealing strips can be improved and the production quality of the sealing strips can be ensured by using a two-color extrusion process.

[0022] In some embodiments, the soft rubber strip portion has a cavity, or the soft rubber strip portion and the hard rubber strip portion enclose a cavity, and the cavity is filled with a foaming material.

[0023] By filling the cavity with foaming material, the deformation recovery ability of the soft rubber strip can be improved, ensuring that the sealing strip can maintain its original shape after long-term use.

[0024] In some embodiments, the cross-section of the engaging protrusion is dovetail-shaped, and the engaging groove is a dovetail groove.

[0025] By designing the cross-section of 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 slot when squeezed by exposed steel bars, thereby improving the wrapping effect of the sealing strip on the exposed steel bars.

[0026] In some embodiments, a raised portion or a recessed portion having a trapezoidal cross-section is provided on one side of the top mold body close to the plate-like component.

[0027] By providing only one raised portion or groove portion, compared to providing multiple raised portions or groove portions, the casting quality of the end face of the plate-like component can be improved, and the risk of damage to the end face of the plate-like component when the side mold structure is disassembled can be reduced.

[0029] 1. The side mold structure for prefabricated plate components provided by the present application has strong versatility and good sealing performance, which improves the utilization rate of the side mold and the production efficiency of prefabricated plate components. At the same time, by setting a perforation on the guide pin, it is convenient to use the perforation to pull out the guide pin, thereby facilitating the separation of the top mold and the bottom film. In addition, by setting the sealing strips respectively clamped on the top mold body and the bottom mold body to the same specifications, the specifications and types of the sealing strips can be reduced, the versatility of the sealing strips can be enhanced, and the production cost of the sealing strips can be reduced.

[0032] 4. The present application provides a side mold structure for prefabricated plate-like components. After the top mold body is pressed onto the bottom mold body, the top and bottom ends of the support parts can respectively abut against the top mold body and the bottom mold body. On the one hand, 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-like components; on the other hand, the bottom end of the support part abuts against the bottom membrane body, which can share the pressure transmitted by the support part borne by the screw connection part. That is to say, the screw connection part and the bottom end of the support part jointly bear the pressure borne by the top end of the support part, thereby reducing the risk of damage to the part where the screw connection part is screwed to the mounting groove.

The hard rubber strip part is harder 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 the bottom mold body), thereby reducing the risk of damage to the soft rubber strip part.

DETAILED DESCRIPTION

[0050] 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 ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0051] In order to simplify the drawings, only the parts related to the present application are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically drawn or marked. In this article, "one" not only means "only one", but also means "more than one".

[0052] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0053] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0054] 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.

[0055] refer to Figure 1-Figure 4 , Figure 6The present application provides a side mold structure for prefabricated plate-like components, including: a top mold body 1, a bottom mold body 2, a support seat 9, a guide pin 6 and a sealing strip 10, the top mold body 1 is provided with a guide hole 3; the bottom mold body 2 is provided with a mounting groove 4 corresponding to the position of the guide hole 3 on one side close to the top mold body 1; the top mold body 1 and the bottom mold body 2 are respectively installed with the same sealing strip 10 on both sides adjacent to each other, and the sealing strip 10 installed on the top mold body 1 and the sealing strip 10 installed on the bottom mold body 2 can be mutually squeezed to make the sealing strip 10 wrapped around the outer periphery of the exposed steel bars of the plate-like component to be cast, so as to prevent leakage of slurry from the side of the plate-like component when casting the plate-like component. In other words, it is to prevent the slurry (concrete) from flowing out of the side mold structure along the exposed steel bars of the plate-like component.

[0056] When the side mold structure is assembled, the support seat 9 is installed in the installation groove 4 and exposed in the installation groove 4, and the exposed end surface of the support seat 9 abuts against the side of the top mold body 1 close to the bottom mold body 2, and the support seat 9 is provided with a slot 5. The support seat 9 is used to control the vertical distance between the top mold body 1 and the bottom mold body 2 to achieve control of the overall thickness of the side mold structure, so that the overall thickness of the side mold structure is adapted to the thickness of the plate-like component.

[0057] It is understandable that when the side mold structure is assembled, the guide pin 6 is inserted into the guide hole 3 and its bottom end is magnetically attracted to the slot 5, and the top end is exposed in the guide hole 3. The top end of the guide pin 6 is provided with a through hole 7 arranged along its transverse direction, and the through hole 7 can provide a force point for the removal of the guide pin 6. That is to say, when the plate-like component is cast using the side mold structure of the present application, when removing the mold, a tool with a hook can be used to hook into the through hole 7 to pull the guide pin 6 out of the slot 5, without the need for workers to bend over to remove the guide pin 6, thereby improving the removal efficiency of the guide pin 6 and reducing the labor intensity of the workers. It is understandable that the guide pin 6 is used to limit the relative horizontal displacement between the top mold body 1 and the bottom mold body 2 to prevent the top mold body 1 from shifting when casting the plate-like component or when the mold platform vibrates (to ensure dense casting), thereby affecting the molding quality of the plate-like component.

[0058] The installation process of the side mold structure of the present application is as follows: the bottom mold body 2 is pressed onto the mold platform for making plate-like components through a magnetic box, and then the steel mesh of the plate-like components to be cast is placed on the sealing strip 10 of the bottom mold body 2, and then the guide pin 6 is inserted into the slot 5 of the support seat 9, and then the top mold body 1 is placed on the bottom mold body 2 through the cooperation of the guide pin 6 and the guide hole 3, so that the sealing strip 10 on the top mold body 1 is pressed on the upper side of one end of the steel mesh (exposed steel bars), and then the top mold body 1 is pressed tightly with a magnetic box, so that the upper and lower sealing strips 10 are wrapped around the outer periphery of the exposed steel bars, and the top end of the support seat 9 is against the top mold body 1, and the assembly of the side mold structure is completed.

[0059] It is easy to understand that the side mold structure has strong versatility and good sealing performance, which improves the utilization rate of the side mold and the production efficiency of prefabricated plate components. At the same time, by setting the perforation 7 on the guide pin 6, it is convenient to use the perforation 7 to pull out the guide pin 6, thereby facilitating the separation of the top mold and the bottom film. In addition, by setting the sealing strips 10 respectively clamped on the top mold body 1 and the bottom mold body 2 to the same specifications, the specifications of the sealing strips 10 can be reduced, the versatility of the sealing strips 10 can be enhanced, and the production cost of the sealing strips 10 can be reduced.

[0060] Specifically, the top mold body 1 and the bottom mold body 2 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 2. Figure 1-Figure 4 Preferably, both the top mold body 1 and the bottom mold body 2 are hollow structures and both ends are blocked by the sealing plate 8. It can be understood that by setting both the top mold body 1 and the bottom mold body 2 as hollow structures, the materials used in the production of the top mold body 1 and the bottom mold body 2 can be saved, and the self-weight of the top mold body 1 and the bottom mold body 2 can be reduced; in addition, by using the sealing plate 8 to block both ends of the top mold body 1 and the bottom mold body 2, it can be prevented that concrete enters the top mold body 1 and the bottom mold body 2 when casting plate-like components.

[0061] In this embodiment, the magnetic attraction between the guide pin 6 and the slot 5 can be achieved by providing a magnetic seat 11 between the two, for example, the magnetic seat 11 is installed at the bottom end of the guide pin 6, or the magnetic seat 11 is installed in the slot 5. Figure 4 It is preferred to install the magnetic seat 11 at the bottom end of the guide pin 6. This solution is easier to implement than fixing the magnetic seat 11 to the slot 5. It is easy to understand that the magnetic connection between the guide pin 6 and the support seat 9 can not only prevent the guide pin 6 from falling off from the slot 5 when the side mold structure vibrates, but also realize the quick disassembly and assembly of the guide pin 6 and the support seat 9.

[0062] refer to Figure 3-Figure 6In one embodiment, the support seat 9 includes a screw connection portion 12 and a support portion 13. After the side mold structure is assembled, the screw connection portion 12 is connected to the bottom end of the support portion 13, the screw connection portion 12 is screwed into the mounting groove 4, the support portion 13 is exposed from the mounting groove 4, and the top and bottom ends of the support portion 13 respectively abut against the adjacent two sides of the top mold body 1 and the bottom mold body 2. It is easy to understand that by enabling the top and bottom ends of the support portion 13 to abut against the top mold body 1 and the bottom mold body 2 respectively, on the one hand, the distance between the top mold body 1 and the bottom mold body 2 can be controlled, thereby achieving control of the overall thickness of the side mold structure, and then matching the thickness of the plate-like component; on the other hand, the bottom end of the support portion 13 abuts against the bottom mold body, which can share the pressure transmitted by the support portion 13 borne by the screw connection portion 12, that is, the bottom ends of the screw connection portion 12 and the support portion 13 jointly bear the pressure borne by the top end of the support portion 13, reducing the risk of damage to the portion where the screw connection portion 12 is screwed to the mounting groove 4. In other embodiments, the support seat 9 is a columnar structure with a uniform outer diameter, the bottom end of the support seat 9 is provided with an external thread, and the mounting groove 4 is provided with an internal thread adapted to the support seat 9. After the side mold structure is assembled, only the screw connection portion 12 between the support seat 9 and the mounting groove 4 bears the pressure borne by the top end of the support seat 9.

[0063] It is worth noting that reference Figure 3-Figure 6 In one embodiment, the guide pin 6 includes a large diameter section 14, a gradient section 15 and a small diameter section 16 connected in sequence, and the cross-sectional size of the large diameter section 14 is adapted to both the guide hole 3 and the slot 5. By setting the guide pin 6 as a large diameter section 14, a gradient section 15 and a small diameter section 16 connected in sequence, the gradient section 15 and the small diameter section 16 play a guiding role, which can facilitate the guide pin 6 to pass through the guide hole 3 on the top mold body 1, reduce the difficulty of the guide pin 6 to penetrate the guide hole 3, and improve the efficiency of the top mold body 1 to be installed on the bottom mold body 2. It can be understood that the through hole 7 is set at the part of the guide pin 6 exposed to the top mold body 1, which can be on the large diameter section 14 or the gradient section 15, or on the small diameter section 16, depending on the length of each section of the guide pin 6 and the depth of the guide hole 3. In other embodiments, the guide pin 6 can be a columnar structure with a uniform outer diameter.

[0064] refer to Figure 3 , Figure 4 , Figure 6-Figure 8In one embodiment, both the top mold body 1 and the bottom mold body 2 are provided with a card slot 17, and the notch of the card slot 17 on the top mold body 1 is arranged opposite to the notch of the card slot 17 on the bottom mold body 2, and the groove walls on both sides of the card slot 17 are provided with a card protrusion 18; the sealing strip 10 includes a soft rubber strip part 20 and a hard rubber strip part 21, the hard rubber strip part 21 is provided with a card slot 19 adapted to the card protrusion 18, the hard rubber strip part 21 is carded in the card slot 17 through the cooperation of the card slot 19 and the card protrusion 18, the soft rubber strip part 20 is exposed in the card slot 17, and the soft rubber strip part 20 can be wrapped around the outer periphery of the exposed steel bar through the mutual extrusion of the upper and lower soft rubber strip parts 20. It is easy to understand that by providing the snap-fit ​​protrusions 18 and the snap-fit ​​grooves 19, the connection strength between the sealing strip 10 and the top mold body 1 and the bottom mold body 2 can be enhanced to prevent the sealing strip 10 from being separated from the top mold body 1 and the bottom mold body 2; by providing the soft strip portion 20 and the hard strip portion 21, the soft strip portion 20 is softer than the hard strip portion 21 and has good filling performance, which is conducive to tightly wrapping around the exposed steel bar periphery and improving the sealing of the side of the plate component, while the hard strip portion 21 is harder than the soft strip portion 20 and can provide strong support for the soft strip portion 20 to ensure the ability of the sealing strip 10 to recover from deformation. At the same time, the hard strip portion 21 also plays a buffering role to prevent the soft strip portion 20 from directly interacting with the top mold body 1 (or the bottom mold body 2) and reduce the risk of damage to the soft strip portion 20.

[0065] It is worth noting that the cross-sectional shape of the clamping protrusion 18 can be rectangular or arc-shaped, or can be dovetail-shaped. Figure 3 , Figure 4 , Figure 6-Figure 8 , preferably, the cross section of the clamping protrusion 18 is dovetail-shaped, and the clamping groove 19 is a dovetail groove. By designing the cross section of the clamping protrusion 18 to be dovetail-shaped and the clamping groove 19 to be a dovetail groove, the connection firmness between the sealing strip 10 and the top mold body 1 (or the bottom mold body 2) can be improved, the risk of the sealing strip 10 returning to the clamping groove 17 when being squeezed by the exposed steel bars can be reduced, and the wrapping effect of the sealing strip 10 on the exposed steel bars can be improved. In other embodiments, only the clamping groove 17 can be provided without the clamping protrusion 18, and the slot size of the clamping groove 17 is small and the size inside the clamping groove 17 is large, that is, the clamping groove 17 is a shrinkage structure, such as a dovetail groove structure.

[0066] It is easy to understand that the soft rubber strip portion 20 can be a foam rubber strip, such as an EPDM foam (sponge) rubber strip, and the hard rubber strip portion 21 can be a hard rubber strip, such as an EPDM rubber strip. This application does not impose any restrictions on the materials of the soft rubber strip portion 20 and the hard rubber strip portion 21.

[0067] 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 10. The sealing strip 10 can also be made by 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 the production efficiency of the sealing strip 10 can be improved by the two-color extrusion process to ensure the production quality of the sealing strip 10.

[0068] It is worth noting that reference Figure 7 , Figure 8 The sealing strip 10 has various structural forms. When the soft strip part 20 of the sealing strip 10 has a cavity, or the soft strip part 20 and the hard strip part 21 enclose a cavity, a foam material 22 can be filled in the cavity. The deformation recovery ability of the foam material 22 should be good. In addition, the effect is better when the hardness of the foam material 22 is less than the hardness of the soft strip part 20. By filling the foam material 22 in the cavity, the deformation recovery ability of the soft strip part 20 can be improved, ensuring that the sealing strip 10 can maintain its original shape after long-term use.

[0069] refer to Figure 1-Figure 4 , Figure 6 In one embodiment, a raised portion 23 or a groove portion 24 with a trapezoidal cross section is provided on one side of the top mold body 1 close to the plate-like component. By providing only one raised portion 23 or groove portion 24, compared with providing multiple raised portions 23 or groove portions 24, the casting quality of the end face of the plate-like component can be improved, and the risk of damage to the end face of the plate-like component when the side mold structure is disassembled can be reduced.

[0070] 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 pointed out 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 regarded as the protection scope of the present application.
