Description

Technical Field

[0001] This application relates to the field of concrete construction mold technology, and in particular to an energy-saving mold for preparing precast concrete components for prefabricated buildings. Background Technology

[0002] In the production and on-site casting of precast concrete components, formwork, as a core forming component, directly determines the appearance quality and structural precision of the finished concrete product. Wooden formwork has long held an important position in the construction industry due to its wide availability of raw materials, ease of processing, and significantly lower cost compared to metal and composite material formwork.

[0003] Compared to airtight metal and plastic formwork, wooden formwork has a naturally porous structure, providing excellent breathability and drainage. After pre-draining the wooden formwork before use, it effectively regulates the humidity environment of the concrete surface during pouring, preventing excessive moisture accumulation or rapid loss at the formwork-concrete contact surface. This maintains stable hydration conditions in the concrete, significantly reducing appearance defects such as honeycomb and pitting caused by uneven moisture distribution, and improving the smoothness of the finished surface.

[0004] However, the inherent defects of wooden formwork are also particularly prominent: its low rigidity makes it prone to deformation such as local bending and overall bulging under the lateral pressure of the grout during concrete pouring, leading to excessive dimensional deviations in precast components; at the same time, wood has poor water resistance and abrasion resistance, and after repeated contact with concrete grout and curing moisture, it is prone to surface peeling, edge cracking, and internal rot, typically only being reused 20-50 times, far shorter than the service life of metal formwork. Frequent formwork replacement not only increases construction costs but also reduces construction efficiency.

[0005] Therefore, there is an urgent need for a mold for preparing precast concrete components that combines the advantages of wooden formwork with structural stability. Summary of the Invention

[0006] This application provides an energy-saving prefabricated concrete component preparation mold, which solves the problems of easy deformation and short service life of wooden formwork in the prior art, and achieves the purpose of improving the service life and assembly efficiency of wooden molds and reducing the deformation problem of wooden molds during the casting process.

[0007] This invention provides an energy-saving prefabricated concrete component preparation mold, comprising: a metal mounting frame and a wooden board; wherein the wooden board is embedded in the metal mounting frame; the metal mounting frame includes: a plurality of metal frames arranged along the edges of the wooden board; and a grid-shaped protective bar, wherein each of the metal frames is slidably disposed at each end of the grid-shaped protective bar; a retracting mechanism is disposed on the side of the wooden board away from the casting surface; the retracting mechanism includes: a turntable assembly located at the center of the metal frames, and a plurality of pull rods; wherein one end of each pull rod is rotatably connected to the surface of the turntable assembly, and the ends of each pull rod near the turntable assembly are spaced apart on a ring centered on the center of the surface of the turntable assembly; the ends of each pull rod away from the turntable assembly are hinged to the surface of the middle region of each group of metal frames.

[0008] In one possible implementation, the metal frame includes: a strip frame with an L-shaped cross-section and an opening facing away from the retracting mechanism; positioning pins spaced apart along the opening of the strip frame; multiple sliders spaced apart along the outer wall of the strip frame; and sliding holes penetrating one side of the slider; wherein the slider is slidably connected to the end of the grid-shaped protective rod through the sliding holes.

[0010] In one possible implementation, the turntable assembly includes: a mounting cylinder disposed on the side of the mounting plate away from the wood panel and coaxially arranged with the mounting plate; an adjusting plate having a through hole at its center that is rotatably connected to the mounting cylinder; multiple insertion holes spaced apart on a ring centered on the center of the adjusting plate; wherein one end of the pull rod is inserted into the insertion hole; a strip-shaped hole disposed on the surface of the adjusting plate; and an adjusting rod having a strip-shaped block, the end of the adjusting rod near the strip-shaped block being embedded in the strip-shaped hole and used to rotate the adjusting plate via the adjusting rod.

[0011] In one possible implementation, the end of the slider away from the sliding hole is closed and connected to a mating block; the middle part of one side of the mating block is connected to the slider and is perpendicular to the slider; there are two sets of mating holes, which are respectively located on the side of the mating block near the slider; wherein the mating holes are respectively located on the upper and lower parts of the slider; the mating holes are used to connect a fixing device or an angle adjustment device; the two ends of the fixing device and the angle adjustment device are respectively embedded in the mating holes of two adjacent molds.

[0012] In one possible implementation, the fixing device includes: a rod for insertion into the mating hole; a fixing member connected to the rod on one side; a tension band detachably connected to the fixing member at one end; and a strip plate, wherein multiple tension bands are provided, and the multiple tension bands are respectively located at each of the top corners of the strip plate.

[0013] In one possible implementation, the angle adjustment device includes: four sets of S-shaped drive rods; wherein each set of drive rods corresponds one-to-one with the four mating holes of two adjacent strip-shaped frames; the drive rods are arranged in pairs, with each set of drive rods connected to two mating holes on the slider; a conical protrusion is located at one end of the drive rod, the conical protrusion being used to embed into the end of the mating hole; two first connecting rods are provided, each set of drive rods having one first connecting rod; wherein one end of the first connecting rod is connected to the corner of the S-shaped drive rod away from the conical protrusion; a vertical plate, with the first connecting rod passing through one end of the vertical plate and rotatably connected to the vertical plate; a screw adjustment assembly is provided on the side of the vertical plate away from the conical protrusion, the two ends of the screw adjustment assembly being connected to the two sets of drive rods respectively, the screw adjustment assembly being used to adjust the size of the openings of the two sets of drive rods near the conical protrusion.

[0014] In one possible implementation, the screw adjusting assembly includes: two sets of second connecting rods, each set located on the side of the first connecting rod away from the conical protrusion, with each end of the second connecting rod connected to one of the two driving rods; two sets of adjusting screws, one end of which is rotatably connected to the middle of the second connecting rod; wherein the two sets of adjusting screws have opposite helical directions and are spaced apart at their ends; and a threaded sleeve, with both ends threadedly connected to the two sets of adjusting screws.

[0015] In one possible implementation, the screw adjustment assembly further includes: a telescopic rod, disposed on the side of the upright plate away from the screw adjustment assembly; the telescopic rod consists of two sets of sleeves that are nested together, one of the sleeves having a threaded hole that penetrates the sleeve and is used to install a fixing bolt; a top rod, vertically disposed at the end of the telescopic rod away from the upright plate; the top rod has a triangular cross-section, and one set of adjacent faces of the triangular cross-section of the top rod abuts against two sets of adjacent strip-shaped frames; and an anti-slip plate, detachably connected to the outer wall of the top rod.

[0016] One or more technical solutions provided in the embodiments of the present invention have at least the following technical effects or advantages: To address the issue of uneven concrete surfaces caused by localized bending due to the rigidity of wooden boards when used as casting templates, the wooden boards are first placed on one side of the grid-shaped protective bars of the metal installation frame before concrete pouring. This ensures that the side of the wooden board furthest from the pouring surface abuts against the protective bars. During the concrete forming process, the protective bars provide uniform support to the back of the wooden board, thereby increasing the rigidity of the boards used in the mold.

[0017] Due to the limited lifespan of wood-based panels, when surface defects such as peeling or breakage occur, tools can be used to drive the retraction mechanism to improve the ease of replacement. For example, inserting one end of a pry bar into the turntable assembly of the retraction mechanism and turning the pry bar causes the turntable assembly to rotate. When the turntable assembly rotates counterclockwise in one direction, it pushes the pull rods outwards from the center of the turntable assembly. This pushes the metal frames connected to the pull rods away from the wood-based panel, causing the metal frames to detach from the wood-based panel, thus achieving the purpose of removing the wood-based panel. Conversely, when the turntable assembly is pried in the opposite direction, it drives the pull rods to move towards the center of the turntable assembly, thus pulling the metal frames to lock onto the edge of the wood-based panel.

[0018] Metal frames not only increase the rigidity of the edges of wood panels, but also protect the edges of the wood panels, improving the problem of easy separation of the edges of traditional plywood. At the same time, by protecting the edges of wood panels with metal frames, the problem of frequent edge warping of traditional plywood during the concrete molding process is avoided.

[0019] The combination of wooden boards and metal frames solves the problems of heavy weight and high production cost of traditional metal formwork. At the same time, it improves the problems of poor air permeability of metal and plastic formwork, large humidity changes at the contact point between concrete slurry and formwork, and the tendency to produce honeycomb pitting on the surface of the formed concrete.

[0020] The natural texture and breathability of the wood-based panels reduce the risk of concrete slurry sticking to the formwork. At the same time, the retracting mechanism can achieve the overall synchronous release of the mold. Because the wood-based panels have weak adhesion to the concrete surface, they can be directly peeled off manually, avoiding damage to the edges and corners of precast components caused by traditional mold knocking and prying, thus improving demolding efficiency.

[0021] Wood-based panels can be made from fast-growing timber, such as poplar and fir, or recycled construction waste wood, achieving resource recycling. Moreover, wood is a natural renewable material, and its production process has lower carbon emissions than steel, avoiding resource waste. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, they should not be construed as limitations on the present invention. The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of the present invention according to the specific circumstances.

[0027] Example 1 Please see Figures 1-11 An energy-saving prefabricated concrete component preparation mold for prefabricated buildings includes: a metal mounting frame 100 and a wooden board 200; wherein the wooden board 200 is embedded in the metal mounting frame 100; the metal mounting frame 100 includes: a plurality of metal frame edges 110 arranged along the edge of the wooden board 200; and a grid-shaped guardrail 120, wherein each of the metal frame edges 110 is slidably disposed at each end of the grid-shaped guardrail 120; and a retracting mechanism 300 disposed at the location away from the wooden board 200. One side of the casting surface; the gathering mechanism 300 includes: a turntable assembly 310 located at the center of the metal frame 110, and a plurality of pull rods 320; wherein, one end of each pull rod 320 is rotatably connected to the surface of the turntable assembly 310, and the end of each pull rod 320 near the turntable assembly 310 is spaced apart on a ring with the center of the surface of the turntable assembly 310 as the center; the end of each pull rod 320 away from the turntable assembly 310 is hinged to the surface of the middle region of each group of metal frames 110.

[0028] In the above embodiments, in order to improve the problem that the wooden board 200 is locally bent due to its own rigidity when used as a casting template, resulting in an uneven surface of the finished concrete, before using the wooden board 200 for concrete pouring, the wooden board 200 is first placed on one side of the grid-shaped protective rod 120 of the metal installation frame 100, so that the side of the wooden board 200 away from the pouring surface abuts against the protective rod 120. During the concrete forming process, the protective rod 120 provides uniform support to the back of the wooden board 200, thereby improving the rigidity of the board used in the mold.

[0029] Due to the limited lifespan of the wooden board 200, when the surface of the wooden board 200 is damaged by peeling or breakage, in order to improve the convenience of replacing the wooden board 200, a tool is used to drive the gathering mechanism 300 to work. For example, one end of the pry bar 317 is inserted into the turntable assembly 310 of the gathering mechanism 300, and the pry bar 317 is moved to make the turntable assembly 310 rotate. When the turntable assembly 310 rotates counterclockwise in one direction, it pushes each pull rod 320 to radiate outwards from the turntable assembly 310 as the center. That is, each pull rod 320 pushes each metal frame 110 connected to the pull rod 320 to move away from the wooden board 200, so that the metal frame 110 is separated from the wooden board 200, thus achieving the purpose of removing the wooden board 200. Conversely, when the turntable assembly 310 is pried in the opposite direction, it drives each pull rod 320 to move closer to the center of the turntable assembly 310, thus pulling each metal frame 110 to be locked at the edge of the wooden board 200.

[0030] The metal frame 110 not only improves the rigidity of the edge of the wood board 200, but also protects the edge of the wood board 200, improving the problem of easy separation of the edge of traditional plywood. At the same time, by protecting the edge of the wood board 200 with the metal frame 110, the problem of edge warping of traditional plywood during the concrete molding process is avoided.

[0031] The combination of 200mm wood panels and 110mm metal frames solves the problems of heavy weight and high production cost of traditional metal formwork. At the same time, it improves the problems of poor air permeability of metal and plastic formwork, large humidity changes at the contact point between concrete slurry and formwork, and the tendency to produce honeycomb pitting on the surface of the formed concrete.

[0032] The natural texture and breathability of the wood-based panel 200 reduce the risk of concrete slurry sticking to the formwork. At the same time, the retracting mechanism 300 can achieve the overall synchronous release of the mold. Because the wood-based panel 200 has weak adhesion to the concrete surface, it can be directly peeled off manually, avoiding damage to the edges and corners of the precast components caused by traditional mold knocking and prying, thus improving demolding efficiency.

[0033] Wood-based panels 200 can be made from fast-growing timber, such as poplar, fir, or recycled construction waste wood, achieving resource recycling. Moreover, wood is a natural renewable material, and its production process has lower carbon emissions than steel, avoiding resource waste.

[0034] Example 2 Please see Figures 1-11The metal frame 110 includes: a strip frame 111 with an L-shaped cross-section and an opening facing away from the retracting mechanism 300; positioning pins 112 spaced apart along the opening of the strip frame 111; sliders 113 spaced apart along the outer wall of the strip frame 111; and sliding holes 114 penetrating one side of the sliders 113; wherein the sliders 113 are slidably connected to the end of the grid-shaped protective rod 120 through the sliding holes 114.

[0035] In the above embodiment, when the pull rod 320 pulls the metal frame 110, the middle part of the strip frame 111 is hinged to the pull rod 320. When it is pulled by the pull rod 320 to move towards the retracting mechanism 300, the slider 113 slides at the end of the protective rod 120. Since the grid-shaped protective rod 120 is formed by four sets of rod-shaped structures, which are parallel to each other and the two sets of rod-shaped structures are perpendicular to each other, the ends of the two sets of parallel rod-shaped structures can guide the movement of the strip frame 111, so that the strip frame 111 is always parallel to one rod-shaped structure during the movement. When the positioning nail 112 on the strip frame 111 is close to the end wall of the wooden board 200, the positioning nail 112 is embedded in the end wall of the wooden board 200, so that the wooden board 200 will not be displaced after installation.

[0036] Example 3 Please see Figures 1-11 It also includes an auxiliary adjustment mechanism 400, which includes: multiple mounting rods 410, one end of which is connected to the protective rod 120 and the other end of which points to the retracting mechanism 300; a mounting plate 420, the edges of which are connected to each of the mounting rods 410, and one side of which is spaced apart from the surface of the wooden board 200; a cross support rod 430, one side of which is used to abut against the side of the wooden board 200 near the retracting mechanism 300, and the other side of which is spaced apart from the mounting plate 420; and an adjusting bolt 440, one end of which passes through the center of the mounting plate 420 and is rotatably connected to the center of the cross support rod 430; wherein the adjusting bolt 440 is threadedly connected to the mounting plate 420.

[0037] In the above embodiments, in order to avoid excessive force on the center of the wooden board 200 causing it to collapse outward, the bending of the center of the wooden board 200 is observed during the concrete pouring process. When bending occurs, the pry bar 317 is inserted into the insertion hole 313 at the end of the adjusting bolt 440. The pry bar 317 is moved to make the adjusting bolt 440 rotate on the surface of the mounting plate 420, causing the end of the adjusting bolt 440 near the cross support rod 430 to push the cross support rod 430 to move, thereby achieving the purpose of leveling the wooden board 200.

[0038] Example 4 Please see Figures 1-11The turntable assembly 310 includes: a mounting cylinder 311 disposed on the side of the mounting plate 420 away from the wooden board 200 and coaxially disposed with the mounting plate 420; an adjusting plate 312 having a through hole at its center that is rotatably connected to the mounting cylinder 311; multiple insertion holes 313 spaced apart on a ring centered on the center of the adjusting plate 312; wherein one end of the pull rod 320 is inserted into the insertion hole 313; a strip hole 314 disposed on the surface of the adjusting plate 312; and an adjusting rod 316 having a strip block 315, one end of the adjusting rod 316 near the strip block 315 being embedded in the strip hole 314 and used to rotate the adjusting plate 312 via the adjusting rod 316.

[0039] In the above embodiment, when the pulling rods 320 are driven by the retracting mechanism 300 to pull the strip frame 111, the end of the adjusting rod 316 with the strip block 315 is inserted into the strip hole 314 of the adjusting plate 312, and the pry bar 317 is inserted into the insertion hole 313 of the adjusting bolt 440. By holding the pry bar 317 and the adjusting rod 316, the included angle between the pry bar 317 and the adjusting rod 316 is increased or decreased, thereby achieving the purpose of driving the adjusting plate 312 to rotate on the outer wall of the mounting cylinder 311. The rotating adjusting plate 312 pushes the pulling rods 320 to move.

[0040] Example 5 Please see Figures 1-11 The slider 113 is closed at one end away from the sliding hole 114 and connected to a mating block 115; the middle part of one side of the mating block 115 is connected to the slider 113 and is perpendicular to the slider 113; there are two sets of mating holes 116, which are respectively located on the side of the mating block 115 near the slider 113; the mating holes 116 are respectively located on the upper and lower parts of the slider 113; the mating holes 116 are used to connect the fixing device 500 or the angle adjustment device 600; the two ends of the fixing device 500 and the angle adjustment device 600 are respectively embedded in the mating holes 116 of two adjacent molds.

[0041] In the above embodiment, when assembling the two sets of molds, the strip frame 111 of the two sets of molds is brought together. If the angle between the wooden boards 200 of the two sets of molds is fixed and no adjustment is needed, such as in conventional vertical assembly, the two ends of the fixing device 500 are inserted into the mating holes 116 on the two adjacent strip frame 111s, and the two sets of molds can be quickly installed by the force applied by the fixing device 500.

[0042] If the included angle between the two sets of molds is not fixed and needs to be adjusted at any time, the angle can be adjusted in real time by connecting the two sets of mating holes 116 through the angle adjustment device 600.

[0043] Example 6 Please see Figures 1-11 The fixing device 500 includes: a plug 510 for inserting into the mating hole 116; a fixing member 520, one side of which is connected to the plug 510; a tension band 530, one end of which is detachably connected to the fixing member 520; and a strip plate 540, wherein multiple tension bands 530 are provided, and the multiple tension bands 530 are respectively provided at each of the top corners of the strip plate 540.

[0044] In the above embodiment, when installing the fixing device 500, the insert rods 510 provided at the ends of each tension band 530 are inserted into the mating holes 116. The tension is provided by the strip plate 540 and the tension band 530, which allows the two sets of molds to be quickly connected. It is worth noting that the tension band 530 and the strip plate 540 are an integral unit. The tension band 530 is connected to the sliding groove provided at the end of the fixing member 520 through the sliding strip provided on it. This allows for the quick replacement of the tension band 530 and the strip plate 540. By selecting tension bands 530 of different lengths, the included angle between the two sets of molds can be changed.

[0045] Example 7 Please see Figures 1-11 The angle adjustment device 600 includes: four sets of S-shaped drive rods 610; each set of drive rods 610 corresponds one-to-one with the four mating holes 116 of two adjacent strip-shaped frame 111; the drive rods 610 are arranged in pairs, and each set of drive rods 610 is connected to two mating holes 116 on the slider 113; a tapered protrusion 620 is provided at one end of the drive rod 610, and the tapered protrusion 620 is used to embed into the end of the mating hole 116; and two first connecting rods 630, with each set of drive rods 610 having one first connecting rod 630. 30; wherein, one end of the first connecting rod 630 is connected to the corner of the S-shaped driving rod 610 away from the conical protrusion 620; a vertical plate 640, the first connecting rod 630 is provided through one end of the vertical plate 640 and is rotatably connected to the vertical plate 640; a screw adjustment assembly 650 is provided on the side of the vertical plate 640 away from the conical protrusion 620, the two ends of the screw adjustment assembly 650 are respectively connected to two sets of driving rods 610, and the screw adjustment assembly 650 is used to adjust the size of the opening of the two sets of driving rods 610 near the conical protrusion 620.

[0046] In the above embodiments, when it is necessary to adjust the included angle of the two sets of molds, the screw adjustment assembly 650 is extended and retracted, causing one end of the drive rod 610 to swing around the first connecting rod 630, so that the ends of the two sets of drive rods 610 away from the screw adjustment assembly 650 move closer or further away from each other. Thus, the drive rods 610 that move closer to each other push the two sets of sliders 113 to move closer together, so that the strip frame 111 is pushed by the sliders 113 and swings along the side edge of the strip frame 111 away from the sliders 113, thereby achieving the purpose of adjusting the included angle of the two sets of molds.

[0047] Example 8 Please see Figures 1-11 The screw adjustment assembly 650 includes: two sets of second connecting rods 651, each set located on the side of the first connecting rod 630 away from the conical protrusion 620, with each end of the second connecting rod 651 connected to one of the two drive rods 610; two sets of adjusting screws 652, one end of which is rotatably connected to the middle of the second connecting rod 651; wherein the two sets of adjusting screws 652 have opposite helical directions and are spaced apart at their ends; and a threaded sleeve 653, with both ends threadedly connected to the two sets of adjusting screws 652.

[0048] In the above embodiment, when it is necessary to adjust the included angle of the drive rod 610, the threaded sleeve 653 is screwed on so that the internal thread provided on the inner wall of the threaded sleeve 653 engages with the two sets of adjusting screws 652. Since the helical directions of the two sets of adjusting screws 652 are opposite, when the threaded sleeve 653 rotates, the two sets of adjusting screws 652 will move closer to each other or further apart.

[0049] It is worth noting that a hexagonal nut is fitted on the outer wall of the threaded sleeve 653. The hexagonal nut is fixedly connected to the outer wall of the threaded sleeve 653, and the threaded sleeve 653 can be driven to rotate on the two sets of adjusting screws 652 by a wrench.

[0050] Example 9 Please see Figures 1-11 The screw adjustment assembly 650 further includes: a telescopic rod 654, disposed on the side of the upright plate 640 away from the screw adjustment assembly 650; the telescopic rod 654 is composed of two sets of sleeves that are nested together, one of the sleeves having a threaded hole 655 that penetrates the sleeve and is used to install a fixing bolt; a top rod 656, vertically disposed at the end of the telescopic rod 654 away from the upright plate 640; the top rod 656 has a triangular cross-section, and one set of adjacent surfaces of the triangular cross-section of the top rod 656 abuts against two sets of adjacent strip-shaped frame 111; and an anti-slip plate 657, detachably connected to the outer wall of the top rod 656.

[0051] In the above embodiment, when the screw adjustment assembly 650 is working, the side of the push rod 656 with the anti-slip plate 657 abuts against the strip frame 111, so that the adjacent strip frames 111 of the two sets of adjacent molds are supported by the strip frame 111 as the included angle changes, so as to avoid the two sets of molds from being misaligned during the angle adjustment process, which would cause the adjacent strip frames 111 of the two sets of molds to be unable to align.
