Description

Technical Field

[0001] The present invention relates to the field of prestressed concrete prefabricated components, and in particular to a mold for producing a prefabricated composite board, a method for producing a prefabricated composite board, and a prefabricated composite board. Background Art

[0002] Traditional cast-in-place composite slabs require on-site formwork, a time-consuming process that significantly reduces construction efficiency. Furthermore, the on-site formwork and subsequent construction steps inevitably cause serious environmental pollution. Large amounts of construction waste, dust pollution, and noise pollution negatively impact the living environment of surrounding residents. Furthermore, traditional cast-in-place floor slabs have a long construction cycle. From formwork and pouring to maintenance, each step requires a significant amount of time. This has become a key factor restricting the overall progress of projects with strict schedule requirements.

[0003] Traditional composite panel molds are usually fixed in size or have a limited adjustment range. The production of panels of different widths requires replacing the entire set of side molds or molds, which is costly, inefficient, and takes up a lot of space.

[0004] Existing adjustable molds often have complex adjustment mechanisms (such as screw adjustment), are cumbersome and time-consuming to operate, have difficulty ensuring positioning accuracy, and lack convenient and reliable locking. The production of laminated panels with surface shaping (such as grooves and ribs) often requires the production of dedicated upper molds or complex removable modules, which have limited versatility.

[0005] When pouring concrete, lightweight filling materials in the mold (such as polystyrene blocks, hollow boxes, etc.) are easily floated and displaced due to the flow and vibration of concrete, affecting product quality and structural performance. Summary of the Invention

[0006] To address the shortcomings of the prior art, the present invention provides a mold for producing prefabricated composite panels, a method for producing prefabricated composite panels, and a prefabricated composite panel. Through a modular design of end and side modules, prefabricated composite panels can be formed simply by changing the shape and size of the end and side modules, significantly reducing operator labor and accommodating small-batch production of various specifications. By replacing the end, side, end, and side modules, composite panels of varying lengths, end shapes, and surfaces can be produced, reducing mold investment costs.

[0012] Furthermore, the compression mold frame includes a mold frame structure, a mold frame pin sleeve and a compression mechanism; the mold frame structure is a frame structure component, and a number of mold frame pin sleeves are respectively provided on both sides of the mold frame structure for positioning with the side mold; a number of height-adjustable compression mechanisms are installed at the bottom of the mold frame structure, and the compression mechanism is located above the mold cavity. By adjusting the height of the compression mechanism, the compression mechanism is used to compress the light core material.

[0013] Furthermore, a plurality of side mold bottom pins are provided on the upper end surface of the side mold, and the mold frame pin sleeve is sleeved on the side mold bottom pin. The matching parts of the mold frame pin sleeve and the side mold bottom pin are respectively provided with a second waist-shaped hole and a third waist-shaped hole. The second waist-shaped hole of the mold frame pin sleeve and the third waist-shaped hole of the side mold bottom pin are tightly matched through a wedge-shaped pin. The inclined surface of the wedge-shaped pin pushes the compression mold frame to move toward the side mold under the action of external force, so that the side mold and the compression mold frame are tightly matched.

[0014] Furthermore, the side mold bottom pin is eccentrically arranged on the upper end surface of the side mold, and the eccentricity between the side mold bottom pin and the center line of the side mold is 100mm-200mm.

[0015] Furthermore, the length of the second waist-shaped hole of the mold base pin sleeve is greater than the length of the third waist-shaped hole of the side mold bottom pin.

[0016] Furthermore, the clamping mechanism includes a pressure plate, an adjusting bolt and a tightening nut. A threaded sleeve is provided at the bottom of the mold frame structure. The two pressure plates are connected by a crossbeam. The crossbeam is installed in the sleeve through an adjusting bolt. A tightening nut is provided between the crossbeam and the sleeve.

[0017] Furthermore, the pressing plate is a steel grid mesh, and the width of the pressing mechanism matches the width of the light core material.

[0022] A second concrete pouring and vibration operation is carried out in the mold cavity to form the inverted tapered ribs on the precast composite panel;

[0024] Furthermore, the light core material is one or a combination of two of EPS, foam, sponge, and XPS.

[0025] A prefabricated composite board is produced using the prefabricated composite board production mold.

[0026] The beneficial effects of the present invention are:

[0027] 1. The mold for producing prefabricated composite panels described in the present invention utilizes a flat mold base, end molds, and side molds to form a mold cavity with an open top. End modules are mounted on the end molds to form the slots at both ends of the prefabricated composite panels. Side modules are mounted on the side molds to form the steps on both sides of the prefabricated composite panels. The modular design of the end and side modules allows the prefabricated composite panels to be formed by simply changing their shape and size, significantly reducing the labor intensity of the operators and accommodating small-batch production of multiple specifications.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0044] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "axial", "radial", "vertical", "horizontal", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0045] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0046] like Figure 1 and Figure 2As shown, the mold for producing prefabricated composite panels described in the present invention includes a flat mold base 1, an end mold 3, a side mold 6, a clamping component and a pressing mold frame 9; the end mold 3 and the side mold 6 are placed on the flat mold base 1, and the flat mold base 1, the end mold 3 and the side mold 6 constitute a mold cavity with an open upper portion, that is, a mold cavity with an open top; a plurality of end modules 4 are installed on the end mold 3 to form the slots at both ends of the prefabricated composite panel; the side modules 5 are installed on the side mold 6 to form the steps on both sides of the prefabricated composite panel; the clamping component is installed on the end mold 3, and the side mold 6 is pressed against the end mold 3 through the clamping component; the pressing mold frame 9 is installed between the two side molds 6 and is located above the mold cavity, and is used to limit the floating or displacement of the light core material 203 in the prefabricated composite panel during the casting process.

[0047] like Figure 4 and Figure 5 As shown, a triangular bar 602 is provided on one side of the side mold 6, and a triangular groove adapted to the triangular bar 602 of the side mold 6 is provided on the end mold 3 for positioning the side mold 6 and the end mold 3. A reinforcement tube is provided on the upper part of the end mold 3, and the clamping component is a clamping hook 7, one end of the clamping hook 7 presses the outer side of the side mold 6, and the other end is inserted into the reinforcement tube on the upper part of the end mold; a first waist-shaped hole is respectively provided at the matching position on the reinforcement tube and the clamping hook 7, and the first waist-shaped hole of the clamping hook 7 is tightly matched with the first waist-shaped hole of the reinforcement tube through a wedge pin 8. Since the edge of the first waist-shaped hole of the clamping hook 7 is at a certain distance from the edge of the first waist-shaped hole of the reinforcement tube, when the wedge pin 8 is inserted into the waist hole and tapped with a hammer to wedge, the inclined surface of the wedge pin 8 pushes the clamping component toward the reinforcement tube 301 under the action of external force, and will press the edge of the first waist-shaped hole of the clamping hook 7 to move toward the waist-shaped hole of the reinforcement tube, until the clamping hook 7 tightens the side mold 6 and the end mold without gap, and the wedge pin 8 is in place, so that the side mold 6 and the end mold 3 are tightly matched.

[0048] The end mold 3 and side mold 6 are respectively installed on the flat mold platform 1 through quick-release locks or quick bolts or buckles. Sealing structures are provided between the end mold 3 and the flat mold platform 1, between the side mold 6 and the flat mold platform 1, and between the end mold 3 and the side mold 6. Generally, rubber strips are used to fill the side seams of the end mold 3 and the side mold 6.

[0049] like Figure 3 As shown, the pressing mold frame 9 includes a mold frame structure, a mold frame pin sleeve 901 and a pressing mechanism; the mold frame structure is a frame structure, and a number of mold frame pin sleeves 901 are respectively provided on both sides of the mold frame structure for positioning with the side mold 6; a number of height-adjustable pressing mechanisms are installed at the bottom of the mold frame structure, and the pressing mechanism is located above the mold cavity. By adjusting the height of the pressing mechanism, the pressing mechanism is used to press the light core material 203.

[0050] A number of side mold bottom pins 601 are provided on the upper end surface of the side mold 6. The side mold bottom pins 601 are arranged on the side mold 6 at an equal distance of 500 mm, and 5-8 are usually arranged. The side mold bottom pins 601 are eccentrically arranged on the upper end surface of the side mold 6, that is, the side mold 6 bottom pins cannot be centrally arranged on the side mold 6. The eccentricity between the side mold bottom pins 601 and the center line of the side mold 6 is 100 mm-200 mm.

[0051] Three sets of pin bushings are installed on both sides of the compression mold frame 9, spaced 1000mm apart. The mold frame pin bushings 901 are fitted onto the side mold bottom pins 601. The mating points between the mold frame pin bushings 901 and the side mold bottom pins 601 are provided with second and third waist-shaped holes, respectively. The second waist-shaped hole of the mold frame pin bushings 901 and the third waist-shaped hole of the side mold bottom pins 601 are tightly fitted together via wedge pins 8. The inclined surface of the wedge pins 8, under the action of external force, pushes the compression mold frame 9 toward the side mold 6, ensuring a tight fit between the side mold 6 and the compression mold frame 9. The second waist-shaped hole of the mold frame pin bushings 901 is longer than the third waist-shaped hole of the side mold bottom pins 601. The lower edge of the second waist-shaped hole of the mold frame pin sleeve 901 is higher than a certain distance from the lower edge of the third waist-shaped hole of the side mold bottom pin 601, and the upper edge of the second waist-shaped hole of the mold frame pin sleeve 901 is higher than a certain distance from the upper edge of the third waist-shaped hole of the side mold bottom pin 601. When the wedge pin 8 is inserted into the waist-shaped hole and tapped with a hammer to wedge it, the inclined surface of the wedge pin 8 will press against the upper edge of the third waist-shaped hole of the side mold bottom pin 601 under the push of external force, pressing the mold frame pin sleeve 901 downward until the mold frame pin sleeve 901 and the side mold bottom pin 601 are tightened without gap, and the wedge pin 8 is in place to fix the compression mold frame 9 and the side mold 6.

[0052] like Figure 6 and Figure 7 As shown, the clamping mechanism includes a pressure plate 904, an adjusting bolt 903, and a tightening nut 902. A threaded sleeve is provided at the bottom of the formwork structure. The two pressure plates 904 are connected by a crossbeam, which is mounted within the sleeve via an adjusting bolt 903. A tightening nut 902 is provided between the crossbeam and the sleeve. The pressure plate is a steel grating mesh, and the width of the clamping mechanism matches the width of the light-core material 203. By rotating the adjusting bolt 903, the height of the pressure plate 904 relative to the upper surface of the side form 6 is adjusted to ensure that all pressure plates 904 are pressed down at equal distances and evenly. The tightening nut 902 is then used to tighten the adjusting bolt 903 to fix the height of the pressure plate 904. The bolts are installed in groups and hoisted at intervals of 500 / 1000 mm. Each set of pressure plates is arranged at equal intervals of 600 mm.

[0053] The side mold 6, the end mold and the bottom mold and the joints between them are covered with sealing strips and sealed by compression.

[0054] A method for producing a prefabricated composite panel using the above-mentioned prefabricated composite panel production mold comprises the following steps:

[0055] Determine the size: Based on the width and length of the prefabricated composite panel 2 to be produced, and in accordance with the product width requirements in the drawing, assemble the mold cavity using the flat mold platform 1, the end mold 3, and the side mold 6, taking 600 mm as the base;

[0056] First concrete pouring: Cage reinforcement is placed in the mold cavity and positioned, and the first concrete pouring and vibration operation is carried out in the mold cavity to form the bottom plate 201 of the prefabricated composite board 2; during the first concrete pouring, the concrete is poured onto the upper edge plane of the triangular bar of the side mold 6 and the surface is scraped flat.

[0057] After the concrete of base slab 201 initially sets, a lightweight core material 203 is placed on top of base slab 201. End modules 4 and side modules 5 are installed on the end mold 3 and side molds 6 around the mold cavity, respectively. A compression mold frame 9 is installed between the two side molds 6 to compress the lightweight core material 203. The lightweight core material 203 can be one of EPS, foam, sponge, or XPS, or a combination of two. EPS is expandable polystyrene foam, and XPS is extruded polystyrene foam.

[0058] The second concrete pouring and vibrating operation is carried out in the mold cavity to form the inverted conical rib 202 on the prefabricated composite plate 2. Figure 8 The pressure plate 904 ensures that the lightweight material does not float or shift.

[0059] Demoulding: After the concrete reaches the required strength, disassemble in reverse order: first loosen the pressing plate 904 and remove it, loosen the clamping parts of the side mould 6 and remove the side mould 6, remove the end mould 3, remove the end module 4 and the side module 5, and finally lift out the formed prefabricated composite panel 2.

[0060] like Figure 8 and Figure 9 As shown, the prefabricated composite panel described in the present invention is a prefabricated composite panel produced using the prefabricated composite panel production mold.

[0061] It should be understood that although this specification is described according to various embodiments, not every embodiment contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0062] The series of detailed descriptions listed above are only specific descriptions of feasible embodiments of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent embodiments or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
