It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0035] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0036] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0037] Prestressed concrete precast beams, as an emerging construction product, are widely used in large-scale factories, logistics warehouses, production workshops, and large-span and large-bay structures. However, existing precast beam molds on the market have a single structure, requiring molds of various specifications to produce precast beams of varying sizes. This is costly, labor-intensive, and time-consuming.

[0038] In view of the above problems, an embodiment of the present invention provides a precast beam mold, which is used to cope with various precast beam heights and significantly reduces the economic cost of the mold.

[0039] See also Figures 1 to 6 The precast beam mold 10 includes a mold base 100 , a base 200 , a pad 300 and a side mold assembly 400 .

[0040] Among them, there are multiple bases 200, the sizes of the multiple bases 200 are different and they are arranged at intervals on the mold platform 100, and the pads 300 are detachably arranged on the bases 200; the side mold groups 400 are arranged between two adjacent bases 200, the number of the side mold groups 400 is at least two, and the two adjacent side mold groups 400 are used together to make prefabricated beams.

[0041] In this embodiment, by setting a plurality of bases 200 of different sizes, precast beams of different widths can be produced according to the bases 200 of different widths; similarly, since the pads 300 are detachably arranged on the base 200, the height of the side mold group 400 relative to the mold platform 100 can be adjusted by replacing the pads 300 of different heights on the base 200, thereby adjusting the height of the side mold group 400 and finally producing precast beams of different heights; it can be seen that the precast beam mold 10 can produce precast beams of various specifications, has strong adaptability, and effectively reduces the economic cost of the mold.

[0042] It can be understood that in actual production, end molds (not shown) are usually provided at both ends of the side mold group 400, that is, a prefabricated beam is made by the two adjacent side mold groups 400, the end molds at both ends and the base 200.

[0043] It can be understood that two adjacent side mold groups 400 are usually arranged on two gaps formed by three adjacent bases 200, that is, one side mold group 400 is arranged between two adjacent bases 200, and the other side mold group 400 is arranged between the other two adjacent bases 200, so that the two adjacent side mold groups 400 and the base 200 located between the two side mold groups 400 can jointly produce prefabricated beams.

[0044] Furthermore, the distance between any two adjacent bases 200 among the plurality of bases 200 is not equal to the distance between any two adjacent bases 200 .

[0045] In this embodiment, the spacing between the multiple bases 200 is set to be uneven, so as to facilitate the casting of precast beams of different specifications and further improve the adaptability of the precast beam mold 10.

[0046] Furthermore, the base 200 is provided with a mounting hole 210 , and at least a portion of the pad 300 is disposed in the mounting hole 210 .

[0047] In this embodiment, by arranging part of the pad block 300 in the mounting hole 210, and making the part outside the mounting hole 210 support the side module 400, and the mounting hole 210 has a good limiting effect on the pad block 300, the pad block 300 is stably installed on the base 200, so that the side module 400 can be stably placed on the pad block 300, thereby ensuring the production quality of the prefabricated beam.

[0048] Furthermore, there are multiple pads 300 , and the multiple pads 300 are staggered between two adjacent bases 200 .

[0049] In this embodiment, any one of the multiple pads 300 on one base 200 of two adjacent bases 200 is aligned with the two closest pads 300 on the other base 200. In other words, the multiple pads 300 on one base 200 are respectively aligned with the gaps between the multiple pads 300 on the other base 200, thereby making the arrangement of the pads 300 more reasonable.

[0050] It can be understood that there are multiple mounting holes 210 , and multiple pads 300 are installed in the multiple mounting holes 210 in a one-to-one correspondence.

[0051] Furthermore, the side mold assembly 400 includes one or more side molds 410 , and the multiple side molds 410 are connected in sequence along the length direction thereof, and two adjacent side molds 410 are connected by fasteners 416 .

[0052] In this embodiment, the side mold assembly 400 is composed of at least one side mold 410. The fasteners 416 may be bolts. When there are at least two side molds 410, two adjacent side molds 410 are fastened together by the bolts. Therefore, by providing different numbers of side molds 410, side mold assemblies 400 of different lengths can be obtained, thereby facilitating adjustment of the length of the precast beam and further improving the adaptability of the precast beam mold 10.

[0053] In detail, the side mold 410 includes a top plate 411 and two oppositely disposed side plates 412 , and the top plate 411 is slidably disposed on top of the two side plates 412 .

[0054] In this embodiment, the two side panels 412 are arranged opposite to each other, and the top of each side panel 412 is slidably engaged with the top panel 411, so that the side panels 412 can move relative to the top panel 411 under the action of external force to adjust the distance between the two side panels 412, thereby facilitating the production of prefabricated beams of different specifications.

[0055] Furthermore, the top plate 411 is provided with hanging nails, which are used to connect with the hanging device, so as to drop the side module 400 through the hanging equipment.

[0056] Furthermore, the side mold 410 also includes a sliding member 413, the bottom wall of the top plate 411 is provided with a support rib 4111, the support rib 4111 is provided with a slide rail 4112, and the sliding member 413 is provided on the top of the side plate 412 and slides with the slide rail 4112.

[0057] In this embodiment, the slide rail 4112 is fixedly connected to the support rib 4111 to ensure that the sliding member 413 arranged on the top of the side panel 412 can slide stably along the slide rail 4112; since the extension direction of the slide rail 4112 is perpendicular to the plane where the side panel 412 is located, when the two side panels 412 are driven to move along the slide rail 4112 through the sliding member 413, the two side panels 412 can move toward each other or away from each other, thereby adjusting the distance between the two side panels 412.

[0058] It can be understood that a sliding member 413 is provided on the top of each side panel 412, and each side panel 412 can be provided with multiple sliding members 413, and multiple sliding rails 4112 are correspondingly provided on the top panel 411, so that the multiple sliding members 413 and the multiple sliding rails 4112 are provided in a one-to-one correspondence, thereby facilitating the movement of the side panel 412 relative to the top panel 411.

[0059] The support ribs 4111 are in a grid shape. In addition to supporting the top plate 411, the support ribs 4111 can also enhance the structural strength of the top plate 411. The slide rails 4112 are arranged on the support ribs 4111 so that the slide member 413 can slide stably with the slide rails 4112.

[0060] Alternatively, in other embodiments of the present invention, Figure 7 As shown, the side mold assembly 400 also includes a fixing member 417 , and the top plate 411 is provided with a movable hole 4113 , which extends in a direction perpendicular to the side plate 412 . The fixing member 417 passes through the movable hole 4113 and is connected to the top of the side plate 412 .

[0061] In this embodiment, the movable hole 4113 is a waist-shaped hole. Therefore, the fixing member 417 is passed through the movable hole by the through hole, so that the fixing member 417 can move along the extension direction of the movable hole 4113, thereby allowing the side plate 412 to move relative to the top plate 411.

[0062] It can be understood that the number of movable holes 4113 and fixing parts 417 is at least two, that is, the two fixing parts 417 are respectively provided with two movable holes 4113 and fixedly connected to the two side panels 412, so as to realize the two side panels 412 to move toward or away from each other relative to the top panel 411, thereby facilitating the adjustment of the distance between the two side panels 412.

[0063] Furthermore, reinforcing ribs 4121 are provided on the opposite walls of the two side panels 412 , and the reinforcing ribs 4121 are in a grid shape, thereby significantly increasing the structural strength of the side panels 412 and ensuring the forming effect of the prefabricated beams.

[0064] Furthermore, the side mold 410 also includes a positioning rod 414 , and both ends of the positioning rod 414 are respectively connected to the two side plates 412 .

[0065] First of all, it should be noted that after the distance between the two side panels 412 is adjusted, a positioning rod 414 with a length corresponding to the distance between the two side panels 412 is installed between the two side panels 412 so that the distance between the two side panels 412 remains unchanged, ensuring the quality of prefabricated beam production.

[0066] Therefore, by providing the positioning rods 414, the two side panels 412 can be fixed and positioned to avoid deformation due to stress during the construction process, which would affect the forming size of the prefabricated beam.

[0067] In detail, one of the side plates 412 is provided with a connecting portion 4122 , and the other side plate 412 is provided with a hooking groove 4123 . One end of the positioning rod 414 is connected to the connecting portion 4122 , and the other end is connected to the hooking groove 4123 .

[0068] In this embodiment, the connecting portion 4122 and the groove are both arranged on the reinforcing rib 4121 of the side panel 412, and the connecting portion 4122 is annular. Therefore, by connecting one end of the positioning rod 414 to the connecting portion 4122 and the other end to the hook groove 4123, the positioning rod 414 is fixed to prevent the side panel 412 from being deformed after long-term use.

[0069] Furthermore, there are two positioning rods 414 , and the two positioning rods 414 are respectively connected to both ends of the side plate 412 in the length direction.

[0070] In this embodiment, positioning rods 414 are provided at both ends of the side panels 412 in the longitudinal direction, so that the force on the side panels 412 is balanced and the stability of the two side panels 412 is further enhanced.

[0071] It is understandable that the number and location of the positioning rods 414 may be other settings, which are not specifically limited here.

[0072] Furthermore, the side mold 410 also includes a limiting plate 415 , which is connected to the side of the top plate 411 . The limiting plate 415 is used to abut against the outer side wall of the side plate 412 .

[0073] In this embodiment, a limiting plate 415 is provided to abut against the outer wall of the side plate 412 to fix and limit the side plate 412, thereby avoiding the risk of stress deformation of the side plate 412 during construction and affecting the forming and production of the prefabricated beam.

[0074] It should be noted that the limit plate 415 is also used to make the top of the prefabricated beam. In other words, the limit plate 415 and the two adjacent side plates 412 and the base 200 located between the two side plates 412 are used together to make the prefabricated beam, and the limit plate 415 can be used to form the top of the prefabricated beam, thereby improving the forming effect and forming quality of the prefabricated beam, ensuring that the top two sides of the prefabricated beam in the length direction are flat, and facilitating the placement of other cooperating components.

[0075] Furthermore, the limiting plate 415 and the top plate 411 are integrally formed.

[0076] In this embodiment, the limiting portion and the top plate 411 are manufactured by an integrated molding process, which is simple and makes the plate structure formed by the connection between the limiting portion and the top plate 411 stronger.

[0077] Specifically, the cross section of the limiting plate 415 is L-shaped.

[0078] Of course, in other embodiments of the present invention, the limiting portion may also have other structures, which are not specifically limited here.

[0079] Furthermore, there are two limiting plates 415 , which are respectively connected to two side edges of the top plate 411 , and are symmetrically arranged.

[0080] In this embodiment, the two limiting parts are respectively connected to the two sides of the top plate 411, so as to respectively fix and limit the two side plates 412, thereby avoiding the side plates 412 from being deformed by force during the construction of the prefabricated beams, thereby effectively improving the forming effect of the prefabricated beams.

[0081] Furthermore, the precast beam mold 10 further includes a bidirectional turbine contraction mechanism 500 , which is disposed between the two side plates 412 and is used to adjust the distance between the two side plates 412 .

[0082] See also Figure 6 The bidirectional turbine contraction mechanism 500 includes a turbine reducer 510 , an input shaft 520 and two output shafts 530 .

[0083] Among them, the input shaft 520 is connected to the turbine reducer 510 in a transmission manner, and the two output shafts 530 are respectively connected to the two ends of the turbine reducer 510. The two output shafts 530 are also used to be connected to the precast beam side formwork 410 plate; the input shaft 520 is used to drive the two output shafts 530 to move relative or oppositely through the turbine reducer 510 under the action of driving force.

[0084] In this embodiment, the input shaft 520 rotates axially under the action of an external driving force, and drives the two output shafts 530 to move synchronously toward or away from each other in the directions of the two ends of the turbine reducer 510 through the turbine reducer 510, thereby driving the side molds 410 plates connected to the two output shafts 530 to move toward or away from each other, thereby adjusting the spacing between the two side molds 410 plates to adapt to the production of prefabricated beams of different sizes; it can be seen that the bidirectional turbine contraction mechanism 500 has a simple structure, reasonable design, and good transmission effect, and can effectively drive the movement of the side molds 410 plates through the two output shafts 530.

[0085] Furthermore, the axes of the two output shafts 530 are arranged in parallel, so that the two output shafts 530 are arranged in a staggered manner.

[0086] In this embodiment, the two output shafts 530 are located in the same horizontal plane and are arranged in parallel, and the two output shafts 530 are respectively located on both sides of the input shaft 520, so that the two output shafts 530 are staggered in the horizontal plane direction, that is, the two output shafts 530 are not located on the same axis; with this arrangement, the structural design of the bidirectional turbine contraction mechanism 500 can be made more reasonable.

[0087] Furthermore, the two output shafts 530 are both threadedly connected to the turbine reducer 510 , and the threads of the two output shafts 530 have opposite rotation directions.

[0088] In this embodiment, precisely because the threads of the two output shafts 530 have opposite rotation directions, when the external driving force drives the input shaft 520 to rotate, the two output shafts 530 are driven to move in opposite directions through the turbine reducer 510, that is, the two output shafts 530 are driven to move toward or away from each other, thereby driving the side molds 410 plates connected thereto to move toward or away from each other through the two output shafts 530, thereby achieving the purpose of adjusting the spacing between the side molds 410 plates.

[0089] Furthermore, the bidirectional turbine contraction mechanism 500 further includes a driving handle 540 , which is connected to the input shaft 520 .

[0090] In this embodiment, the operator manually rotates the driving handle 540 to drive the input shaft 520 to rotate, and thereby drives the two output shafts 530 to move through the turbine reducer 510, and finally the two output shafts 530 drive the two side molds 410 plates to move toward or away from each other, thereby achieving the purpose of adjusting the distance between the two side molds 410 plates.

[0091] It is worth mentioning that the driving handle 540 is detachably connected to the input shaft 520 , thereby facilitating the installation or removal of the driving handle 540 .

[0092] Furthermore, a clamping portion 521 is provided at the end of the input shaft 520 , and a clamping slot adapted to the clamping portion 521 is provided on the driving handle 540 , and the clamping portion 521 is clamped and matched with the clamping slot.

[0093] In this embodiment, by engaging the card slot of the driving handle 540 with the card holding portion 521 of the input shaft 520, when the driving handle 540 is connected to the input shaft 520, it is ensured that the input shaft 520 can rotate synchronously with the driving handle 540, thereby preventing the driving handle 540 and the input shaft 520 from sliding relative to each other.

[0094] Furthermore, there are multiple turbine reducers 510 , and the multiple turbine reducers 510 are coaxially arranged through the input shaft 520 , and each turbine reducer 510 is connected to two output shafts 530 .

[0095] In this embodiment, multiple turbine reducers 510 are provided, and each turbine reducer 510 is connected to two output shafts 530, so that the output shafts 530 of the multiple turbine reducers 510 act together on the side mold 410 plate, thereby making the side mold 410 plate move faster.

[0096] Specifically, the number of the turbine reducers 510 is two; of course, in other embodiments, the number of the turbine reducers 510 can also be other settings, which is not specifically limited here.

[0097] Furthermore, the bidirectional turbine retraction mechanism 500 also includes a fastening rod 550, which is used to connect to the side mold 410 plate, and the multiple output shafts 530 located on the same side of the multiple turbine reducers 510 are all connected to the fastening rod 550.

[0098] In this embodiment, a fastening rod 550 is provided for connecting to the side mold 410 plate, and multiple output shafts 530 on the same side of multiple turbine reducers 510 are connected to the same fastening rod 550, so that the output shafts 530 of multiple turbine reducers 510 can act more stably on the side mold 410 plate.

[0099] Furthermore, the bidirectional turbine contraction mechanism 500 also includes a rod sleeve 560 , which is used to be set on the side mold 410 plate, and the rod sleeve 560 is also sleeved outside the fastening rod 550 .

[0100] In this embodiment, the rod sleeve 560 is sleeved on the outside of the fastening rod 550 and vertically attached to the reinforcing rib 4121 of the side mold 410 plate, and connects the output shaft 530 with the fastening rod 550, so that the force of the output shaft 530 is stably transmitted to the side plate 412 through the fastening rod 550 and the rod sleeve 560.

[0101] In detail, there are multiple rod sleeves 560 , which are arranged at intervals and are collectively sleeved outside the fastening rod 550 .

[0102] In this embodiment, the number of the rod sleeves 560 is two; of course, in other embodiments, the number of the rod sleeves 560 can also be other settings, which is not specifically limited here.

[0103] In summary, an embodiment of the present invention provides a precast beam mold 10, which can produce precast beams of different widths according to the bases 200 of different sizes by setting a plurality of bases 200 of different sizes; similarly, since the pad 300 is detachably arranged on the base 200, the height of the side mold group 400 relative to the mold platform 100 can be adjusted by replacing the pads 300 of different heights on the base 200, thereby adjusting the height of the side mold group 400 and finally producing precast beams of different heights; it can be seen that the precast beam mold 10 can produce precast beams of various specifications, has strong adaptability, and effectively reduces the economic cost of the mold.

[0104] Furthermore, the present invention also provides a precast beam production method, which is applied to the precast beam mold 10 as described in any one of the above embodiments. The precast beam production method includes the following steps:

[0105] In step S100 , a spacer block 300 of a corresponding size is selected according to a preset size of the precast beam, and the spacer block 300 is installed on a base.

[0106] In this embodiment, the size of the prefabricated beam to be produced needs to be determined before production, and therefore a spacer block 300 of an appropriate size needs to be selected according to the size.

[0107] Specifically, the step of selecting the pad 300 includes the following sub-steps:

[0108] Sub-step S110, selecting the corresponding production line on the anchor seat according to the project drawings to prepare for construction;

[0109] Sub-step S120, confirming the height of the selected prefabricated beam to be produced;

[0110] In sub-step S130, corresponding pads 300 are selected in the production area corresponding to the anchor seat according to the height change of the precast beam.

[0111] The mold platform 100 is designed with a wall-like base 200, the height of the base 200 is 350 mm, and the height of the side mold group 400 is 1000 mm.

[0112] In this embodiment, in the initial state, without setting the spacer block 300, a 650mm high precast beam can be produced (the height of the side mold group 400 minus the height of the base, that is, 1000mm-350mm=650mm); if a precast beam with a height of 700mm is produced, a 50mm high spacer block 300 is selected (the height of the side mold group 400 minus the height of the base, that is, 1000mm-350mm+50mm=700mm), and the height changes of the precast beams produced subsequently are similar.

[0113] In step S200 , the side mold assembly 400 is adjusted to an open state, and the side mold assembly 400 is placed on the spacer 300 between two adjacent bases.

[0114] In this embodiment, the distance between the two side plates 412 of the side mold assembly 400 is adjusted by the bidirectional turbine contraction mechanism 500 so as to be compatible with the two adjacent bases 200 , thereby adjusting the two side plates 412 in the side mold assembly 400 to an open state.

[0115] It should be noted that this process presupposes that the precast beam strands have been tensioned and the rebar required by the design drawings has been installed. Specifically, the precast beam side mold assembly 400 is installed between two adjacent precast beam production lines. Once the side mold assembly 400 is in place, the drive handle 540 is manually rotated to push the two side panels 412 outward until they abut against the adjacent bases. Finally, a positioning rod 414 is installed between the two side panels 412 to complete the installation.

[0116] It should also be noted that there need to be at least two side module groups 400, and the two side module groups 400 are respectively set between the gaps formed by three adjacent bases, that is, one side module group 400 is installed between two adjacent bases 200, and the other side module group 400 is installed between the other two adjacent bases 200.

[0117] Step S300: Install end molds at both ends of the side mold assembly 400 and pour concrete.

[0118] In this embodiment, after the tensioning of the steel strands in the precast beam is completed, the installation of the steel bars designed in the drawings is completed and accepted, the formwork at both ends of the precast beam, that is, the end formwork, is installed. The function of the formwork is to separate the head and tail precast beams and divide the continuous precast beams on the same platform, that is, to divide a whole precast beam into multiple independent precast beams through the beam end formwork, and then pour concrete.

[0119] In step S400 , the side mold assembly 400 is adjusted to a contracted state and demolding is performed.

[0120] In this embodiment, after the concrete is formed, the positioning rods 414 are removed, and the two side panels 412 are retracted inwardly by the retraction mechanism 500 to adjust the two side panels 412 to a retracted state, and then the top panel 411 is lifted by the lifting equipment for demoulding.

[0121] Specifically, step S400 further includes the following sub-steps:

[0122] Sub-step S410: After the precast beam concrete construction is completed, it is necessary to wait for at least about 8 hours to ensure that the concrete is completely solidified.

[0123] Sub-step S420 , starting from both ends of the production line toward the middle, undo the positioning rods 414 of the side mold assemblies 400 one by one;

[0124] In sub-step S430, the driving handle 540 is manually rotated in the reverse direction to retract the two side panels 412 so as to move the side panels 412 inwardly and retract, thereby separating the side panels 412 from the concrete surface of the precast beam.

[0125] Sub-step S440, after completing the side form retraction operation, use the gantry crane on the pedestal to perform the lifting operation, and move the side form assembly 400 away from the precast beam production line where production has been completed, and move it to the next precast beam production line to repeat the operation.

[0126] The foregoing description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be readily conceived by a person skilled in the art within the technical scope disclosed herein are intended to be encompassed within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
