Description

Technical Field

[0001] This invention relates to the field of concrete casting mold technology, specifically a quick-release prestressed concrete square pile one-time forming mold. Background Technology

[0002] Precast concrete square piles are a widely used pile foundation material in construction engineering. They are mainly used to compensate for unstable or poorly supported soil layers to support and stabilize buildings. Prestressed concrete square piles are precast square-section piles with pre-tension applied to the internal steel bars before concrete pouring. The pre-stress enhances the crack resistance and bearing capacity of the pile body. Concrete square pile forming molds are special equipment used for mass production of square-section concrete square piles. They are standardized and reusable.

[0003] Existing concrete square pile forming molds are integrally formed by welding, with two second side plates welded to the bottom plate. First side plates are set at both ends, and the first side plates are usually hinged to the main body and fixed with a locking mechanism or bolts. Although the existing technology increases the strength of the main body to a certain extent by welding, the side plates and the bottom plate are welded together, so the mold cannot be disassembled. At the same time, if the side plates are damaged, the mold cannot replace the damaged parts, which increases the economic cost. In addition, it occupies a lot of transportation space, so the quantity that can be transported at one time is small, which increases the transportation cost. Meanwhile, after the mold side plate and the bottom plate are welded together to form an integral closed structure, when the concrete square pile is processed and the material is taken out, the concrete solidifies and adheres tightly to the inner wall of the side plate. When the concrete square pile is lifted, it is easy to cause the surface of the square pile to peel off or the edges to break, thereby reducing the forming quality of the concrete square pile.

[0004] Therefore, the present invention provides a quick-release prestressed concrete square pile one-time forming mold that can be quickly disassembled and is less likely to cause damage to the surface or edges of the square pile during transportation. Summary of the Invention

[0005] To address the problem that existing concrete square pile forming molds cannot be disassembled, a quick-release prestressed concrete square pile one-time forming mold has been designed.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a quick-release prestressed concrete square pile one-time forming mold, including a base plate, the two ends of the base plate are detachably connected to a first forming mechanism symmetrically arranged, the upper end of the base plate is symmetrically arranged with a second forming mechanism, and a support mechanism is provided on one side of the second forming mechanism; The first forming mechanism includes a first side plate and a snap-fit ​​part for connecting the first side plate and the bottom plate. The snap-fit ​​part is detachably connected to a buckle part for snap-fit ​​fixing the connection between the first side plate and the bottom plate. The second forming mechanism includes a second side plate and elastic rotating shafts at both ends of the bottom of the second side plate that are rotatably connected to the base plate. These shafts are used to form the side wall of the mold and can rotate outward to detach from the concrete square pile. An unlocking part is provided on the side of the elastic rotating shaft away from the second side plate, which is used to apply pressure to the elastic rotating shaft to release it from the rotatable connection with the base plate and thus disassemble the second side plate. The support mechanism includes an installation part for connecting the first forming mechanism and the base plate. The installation part is provided with multiple sets of slidably adjustable abutment support members and longitudinally movable abutment adjustment members. The longitudinal movement of the abutment adjustment members drives the abutment support members to slide and make them abut against the second side plate, thereby providing abutment support for the second side plate to improve its compressive strength when processing concrete square piles.

[0007] Furthermore, the second forming mechanism also includes a rotating part fixedly connected to the bottom of the second side plate, a first spring fixedly connected to one end of the elastic rotating shaft away from the bottom plate, and an unlocking part including an unlocking member slidably connected to the inside of the bottom plate at one end, a second spring and an abutment rod fixedly connected to one end of the unlocking member located inside the bottom plate, which is used to compress the second spring and drive the abutment rod to slide and apply pressure to the elastic rotating shaft when pressure is applied to the unlocking member.

[0008] Furthermore, the rotating part is located at the bottom of the upper surface of the base plate, one side of the second side plate abuts against and separates from the support mechanism, the end of the elastic rotating shaft away from the base plate is rotatably connected to the inside of the rotating part, the end of the first spring away from the elastic rotating shaft is fixedly connected to the inner side wall of the rotating part, the abutting rod can slide inside the base plate when it is under force, the end of the second spring away from the unlocking member is fixedly connected to the inside of the base plate, and is used to reset the unlocking member. When the elastic rotating shaft is compressed, it slides inside the rotating part by compressing the first spring to release the rotational connection with the base plate.

[0009] Furthermore, the support mechanism also includes a driving member for driving the longitudinal movement of the abutment adjustment member. The portion of the driving member located inside the abutment adjustment member is threadedly connected to the abutment adjustment member. The abutment support member is symmetrically provided with elastic members for driving the abutment support member to reset. The mounting part includes a first mounting member detachably connected to the first forming mechanism and a second mounting member provided at the bottom of the first mounting member and slidably connected to the base plate. A connecting rod is fixedly connected between the first mounting member and the second mounting member. The abutment support member is slidably connected to the second mounting member. The end of the elastic member away from the abutment support member is fixedly connected to the inner side of the second mounting member. The abutment support member is abutted against the abutment adjustment member through an inclined surface.

[0010] Furthermore, the first forming mechanism includes a first side plate detachably connected to the base plate. The side of the first side plate away from the second side plate has a first adjustment groove symmetrically provided. The side of the first side plate close to the second side plate has a second adjustment groove and a sliding groove symmetrically provided. A snap-fit ​​component is slidably connected inside the first adjustment groove. A snap-fit ​​block is symmetrically arranged protruding at the bottom end of the first side plate. A first buckle component is detachably connected inside the snap-fit ​​block. A second buckle component is detachably connected inside the second adjustment groove.

[0011] Furthermore, during installation, the second side plate can slide inside the slide groove via an elastic pivot. The first mounting component and the second adjustment groove are detachably connected. The second snap fastener is used to snap the first mounting component and the second adjustment groove, so that the first mounting component is fixedly connected to the first side plate. The snap fastener can rotate inside the first adjustment groove and move longitudinally to achieve snap fastening between the first side plate and the bottom plate.

[0012] Furthermore, the base plate includes mounting grooves symmetrically opened at the upper end for mounting the second side plate, and snap-fit ​​grooves and snap-fit ​​holes symmetrically opened at both ends of the base plate for connecting the first side plate. The upper ends of both sides of the base plate have evenly distributed snap-fit ​​blocks protruding from them.

[0013] Furthermore, the two ends of the mounting groove are rotatably connected to the elastic rotating shaft, which is used to support the rotating part at the bottom of the second side plate and allow it to rotate and adjust inside the mounting groove. The protruding snap-fit ​​block at the bottom of the first side plate is snapped into the base plate through the snap-fit ​​groove, and the first snap fastener is inserted into the snap-fit ​​groove and the snap-fit ​​block to achieve a fixed connection between the first side plate and the base plate. The snap-fit ​​element is snapped into the base plate through the snap-fit ​​hole.

[0014] Furthermore, the upper parts of both ends of the mounting groove are transitionally connected to the bottom of the slide groove. When the second side plate is installed, the bottom rotating part slides from the slide groove into the mounting groove through the elastic rotating shaft. Several sets of top fixing parts are provided on the upper part of the two second side plates.

[0015] The beneficial effects of this invention are: (1) The quick-release prestressed concrete square pile one-time forming mold of the present invention realizes the detachable connection between the first forming mechanism and the base plate through the snap-fit ​​block, snap-fit ​​groove and the first snap fastener. Then, the rotation adjustment and quick disassembly of the second forming mechanism are realized through the cooperation of the elastic rotating shaft, the first spring, the unlocking part and the abutment rod. Then, the support mechanism is detachably installed through the cooperation of the first mounting part and the second mounting part with the second snap fastener. Through the detachable setting of the base plate, the first forming mechanism, the second forming mechanism and the support mechanism, the transportation space occupation is effectively reduced, thereby increasing the transportation volume each time, and reducing the transportation cost.

[0016] (2) The quick-release prestressed concrete square pile one-time forming mold of the present invention, through the rotatable setting of the second forming mechanism, allows the second side plate to be rotated outward during the handling of the concrete square pile, so that it can be completely separated from the concrete square pile. This avoids the problem of surface peeling and damage at the edges of the concrete square pile due to friction caused by the close contact between the side plate and the concrete square pile, thereby improving the overall quality of the concrete square pile during handling. At the same time, the second side plate is supported at multiple points by the internal abutting support of the support mechanism, preventing the pressure from concentrating at the connection between the second side plate and the bottom plate during concrete pouring, thereby reducing the risk of deformation of the second side plate. The support mechanism, together with the first forming mechanism and the bottom plate, forms a stable frame to increase the overall strength of the mold. Attached Figure Description

[0020] To make the technical means, technical features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] Example: Figure 1 - Figure 18As shown, the quick-release prestressed concrete square pile one-time forming mold of the present invention includes a base plate 1, with symmetrically arranged first forming mechanisms 2 detachably connected to both ends of the base plate 1, and symmetrically arranged second forming mechanisms 3 on the upper end of the base plate 1. A support mechanism 4 is provided on one side of the second forming mechanism 3. The first forming mechanism 2 includes a first side plate 21 and a snap-fit ​​part for connecting the first side plate 21 and the base plate 1. A snap-fit ​​part is detachably connected inside the snap-fit ​​part for snap-fit ​​fixing the connection between the first side plate 21 and the base plate 1. The second forming mechanism 3 includes a second side plate 31 and elastic rotating shafts 33 arranged at both ends of the bottom of the second side plate 31 and rotatably connected to the base plate 1 for forming the mold. The elastic rotating shaft 33 has a side wall and can rotate outward to detach from the concrete square pile. The side away from the second side plate 31 is provided with an unlocking part, which is used to apply pressure to the elastic rotating shaft 33 to release it from the rotational connection with the base plate 1 and thus disassemble the second side plate 31. The support mechanism 4 includes an installation part for connecting the first forming mechanism 2 and the base plate 1. The installation part is provided with multiple sets of slidably adjustable abutting support members 44 and longitudinally movable abutting adjustment members 47. The longitudinal movement of the abutting adjustment members 47 drives the abutting support members 44 to slide and abut against the second side plate 31, which is used to abut against the second side plate 31 to improve its compressive strength when processing the concrete square pile.

[0022] Specifically, the first side plate 21 is snapped into the base plate 1 through a snap-fit ​​part, and the first side plate 21 is fixedly connected to the base plate 1 by a snap-fit ​​part that is inserted into the base plate 1 and the snap-fit ​​part. When disassembling the first side plate 21, the snap-fit ​​part can be pulled out to remove the first side plate 21. The second side plate 31 is rotatably connected to the base plate 1 through elastic rotating shafts 33 set at both ends of the bottom. When transporting the concrete square pile, the second side plate 31 can rotate with the axis of the elastic rotating shaft 33 to detach from the concrete square pile. Since the rotating part 32 at the bottom of the second side plate 31 is located below the end face of the base plate 1, the second side plate 31 can be completely detached from the concrete square pile by rotating to the side away from the concrete square pile. This avoids the problem of the side wall of the second side plate 31 being tightly attached to the concrete square pile during the transport of the concrete square pile, which would cause inconvenience in material handling and damage to the surface and edges of the square pile. This improves the surface quality of the concrete square pile during transport. Simultaneously, during installation, the second side plate 31 is compressed by the elastic rotating shafts 33 at both ends of the bottom and slides inside the sliding groove 24 into the mounting groove 11. The elastic rotating shafts 33 reset and rotate inside the mounting groove 11, making the second side plate 31 rotatably connected to the bottom plate 1. When disassembling the second side plate 31, pressure is applied to the unlocking part, which drives the elastic rotating shafts 33 to compress, causing the second side plate 31 to disengage from the rotatable connection with the bottom plate 1, thereby achieving rapid disassembly of the second side plate 31. When processing concrete square piles, the first forming mechanism 2 and the second forming mechanism 3 cooperate with the bottom plate 1. Plate 1 forms a square processing mold. The contact adjustment member 47 drives the contact support member 44 to move to contact the second side plate 31. The contact support member 44 supports the second side plate 31 to improve its compressive strength when processing concrete square piles. Several sets of contact support members 44 disperse the force on the second side plate 31, avoiding the pressure exerted by the concrete square pile on the second side plate 31 from tending to the connection between the second side plate 31 and the bottom plate 1, resulting in uneven force distribution and local deformation, which could lead to damage to the second side plate 31 or possible detachment from the bottom plate 1.

[0023] In this embodiment, the second molding mechanism 3 further includes a rotating part 32 fixedly connected to the bottom of the second side plate 31, and a first spring 34 fixedly connected to one end of the elastic rotating shaft 33 away from the bottom plate 1. The unlocking part includes an unlocking member 35 slidably connected to the inside of the bottom plate 1 at one end. A second spring 37 and a stop rod 36 are fixedly connected to one end of the unlocking member 35 located inside the bottom plate 1. When the unlocking member 35 is pressed, the second spring 37 is compressed and the stop rod 36 is driven to slide and press the elastic rotating shaft 33. When the second side plate 31 is installed, the bottom rotating part 32 slides from the slide groove 24 into the installation groove 11 through the elastic rotating shaft 33.

[0024] Specifically, such as Figure 7 - Figure 10As shown, when the second side plate 31 is installed, it can slide inside the slide groove 24 via the elastic rotating shaft 33. The rotating part 32 is located at the bottom of the upper end face of the base plate 1. The second side plate 31 can be rotated at any angle away from the concrete square pile to completely detach it from the concrete square pile. One side of the second side plate 31 abuts against and separates from the support mechanism 4. The end of the elastic rotating shaft 33 away from the base plate 1 is rotatably connected to the inside of the rotating part 32. The end of the first spring 34 away from the elastic rotating shaft 33 is fixedly connected to the inner side wall of the rotating part 32. When the abutment rod 36 is under force, it can slide inside the base plate 1. The end of the second spring 37 away from the unlocking part 35 is fixedly connected to the inside of the base plate 1. The second spring 37 is used to reset the unlocking component 35. When the elastic rotating shaft 33 is pressed, it slides inside the rotating part 32 by compressing the first spring 34 to release the rotational connection with the base plate 1. At this time, the second side plate 31 can be disassembled. The second side plate 31 can be installed through the elastic rotating shaft 33. Then, the unlocking component 35 drives the abutment rod 36 to press the elastic rotating shaft 33 to compress it, thereby completing the disassembly of the second side plate 31 and making the second side plate 31 completely separate from the base plate 1, thereby reducing the space occupied during transportation and reducing transportation costs. The second forming mechanism 3 can also be set to any other mechanism that can achieve the same effect.

[0025] In this embodiment, the support mechanism 4 further includes a driving member 46 for driving the longitudinal movement of the abutment adjustment member 47. The portion of the driving member 46 located inside the abutment adjustment member 47 is threadedly connected to the abutment adjustment member 47. The abutment support member 44 is symmetrically provided with elastic members 45 for driving the abutment support member 44 to reset. The mounting part includes a first mounting member 41 detachably connected to the first molding mechanism 2 and a second mounting member 42 provided at the bottom of the first mounting member 41 and slidably connected to the base plate 1. A connecting rod 43 is fixedly connected between the first mounting member 41 and the second mounting member 42. The abutment support member 44 is slidably connected to the second mounting member 42. One end of the elastic member 45 away from the abutment support member 44 is fixedly connected to the inner side of the second mounting member 42. The abutment support member 44 is abutted to the abutment adjustment member 47 through an inclined surface.

[0026] Specifically, such as Figure 1 and Figure 14 - Figure 18As shown, the driving component 46 can be configured to rotate the top wheel and, in conjunction with the threaded bottom, drive the abutment adjustment component 47 to move longitudinally. The driving component 46 is fixedly and rotatably mounted on the first mounting component 41. The driving component 46 can drive the abutment adjustment component 47 to move upward by rotating forward and downward by rotating in reverse. It then abuts and presses against the abutment support component 44 through the inclined surface, moving it towards the second side plate 31 to support it. The driving component 46 can also be configured with any other structure that achieves the same effect. The first mounting component 41 is detachable through the second adjustment groove 23. The first mounting member 41 is connected to the inside of the first side plate 21 and is fixedly connected to the first side plate 21 by the second fastener 28. The connecting rod 43 is used to fix the first mounting member 41 and the second mounting member 42. The bottom of the second mounting member 42 is slidably connected to the bottom plate 1. The abutting support member 44 is slidably connected to the upper end of the second mounting member 42. When the driving member 46 drives the abutting adjustment member 47 to reset, the abutting adjustment member 47 is driven by the elastic member 45 to reset and move. The elastic member 45 can be set as a spring, or it can be set as any other structure that can achieve the same effect.

[0027] In this embodiment, the first forming mechanism 2 includes a first side plate 21 detachably connected to the base plate 1. The side of the first side plate 21 away from the second side plate 31 has a first adjusting groove 22 symmetrically provided. The side of the first side plate 21 close to the second side plate 31 has a second adjusting groove 23 and a sliding groove 24 symmetrically provided. A snap-fit ​​member 25 is slidably connected inside the first adjusting groove 22. A snap-fit ​​block 26 is symmetrically arranged protruding from the bottom end of the first side plate 21. A first snap-fit ​​member 27 is detachably connected inside the snap-fit ​​block 26. A second snap-fit ​​member 28 is detachably connected inside the second adjusting groove 23.

[0028] Specifically, such as Figure 3 - Figure 6As shown, the snap-fit ​​part includes a snap-fit ​​block 26, and the latching part includes a first latching member 27. A first adjusting groove 22 is used to adjust the position of the snap-fit ​​member 25. The snap-fit ​​member 25 can rotate and move longitudinally within the first adjusting groove 22 to achieve snap-fit ​​between the first side plate 21 and the bottom plate 1. Simultaneously, when disassembling the first side plate 21, the snap-fit ​​member 25 can be adjusted into the first adjusting groove 22 for storage. A rotating pull ring is provided at the outer end of the first latching member 27 on the second latching member 28, facilitating removal during disassembly and allowing it to be fixed with the protrusion at the upper end, preventing detachment due to vibration generated during concrete pile processing. The bottom protrusion of the first side plate 21 engages... Block 26 is snapped into the base plate 1 via the snap-fit ​​groove 12, and the first side plate 21 is fixedly connected to the base plate 1 by inserting the first snap fastener 27 into the snap-fit ​​groove 12 and the snap-fit ​​block 26. The snap fastener 25 is snapped into the base plate 1 via the snap-fit ​​hole 13. When disassembling the first side plate 21, the restriction on the snap-fit ​​block 26 can be released by pulling out the first snap fastener 27, and the first side plate 21 can be removed from the ground. In conjunction with the disassembly of the second side plate 31, the space occupied by the molding mold during transportation and the transportation cost are further reduced. The two sets of first molding mechanisms 2 can be further improved with the support mechanism 4 that is detachably connected between them. At the same time, the first molding mechanism 2 can also be set to any other structure that can achieve the same effect.

[0029] In this embodiment, the base plate 1 includes mounting grooves 11 symmetrically opened at the upper end for mounting the second side plate 31, and snap-fit ​​grooves 12 and snap-fit ​​holes 13 symmetrically opened at both ends of the base plate 1 for connecting the first side plate 21. The upper ends of both sides of the base plate 1 are raised with evenly distributed snap-fit ​​blocks 14, and the upper ends of the two second side plates 31 are provided with several sets of top fixing members 5.

[0030] Specifically, such as Figure 3 , Figure 4 and Figure 7 , Figure 11As shown, the mounting groove 11 is used to install the second forming mechanism 3, and allows the second forming mechanism 3 to rotate inside it. Both ends of the mounting groove 11 are rotatably connected to the elastic rotating shaft 33, which supports the rotating part 32 at the bottom of the second side plate 31 and allows it to rotate and adjust inside the mounting groove 11. The upper parts of both ends of the mounting groove 11 are transitionally connected to the bottom of the sliding groove 24, so that when the second side plate 31 slides into the mounting groove 11, the elastic rotating shaft 33 resets and rotatably connects to the inside of the mounting groove 11. The snap-fit ​​groove 12 is used to snap into the snap-fit ​​block 26 when the first side plate 21 is installed. The first snap-fit... The component 27 can be inserted into the snap-fit ​​slot 12 and fixed to the first side plate 21 by inserting into the snap-fit ​​block 26. The snap-fit ​​hole 13 is used to connect the snap-fit ​​component 25 to stabilize both sides of the first side plate 21. The second mounting component 42 is slidably connected to the base plate 1 through the snap-fit ​​block 14. The top fixing component 5 can be set as a rotating rod with a snap-fit ​​slot on one side and can be rotated and adjusted. The rotating rod is used to lock the fixing column and tighten it with the nut to further fix the symmetrically arranged second side plate 31 and prevent it from deforming under pressure. This is the prior art, so it will not be described in detail.

[0031] Working principle: First, when the molding mold needs to be installed, the bottom snap-fit ​​block 26 of the first side plate 21 is snapped into the corresponding snap-fit ​​groove 12 at the upper end of the base plate 1, and the snap-fit ​​piece 25 is rotated and then moved longitudinally into the corresponding snap-fit ​​hole 13 of the base plate 1. Then, the first snap-fit ​​piece 27 is snapped into the snap-fit ​​groove 12 and into the snap-fit ​​block 26. Next, the first side plate 21 and the base plate 1 are fixed by snapping the pull ring on one side of the first snap-fit ​​piece 27 into the upper protrusion. After the two sets of first molding mechanisms 2 are installed, the second molding mechanism 3 can be installed. By sliding the elastic shafts 33 at both ends of the rotating part 32 at the bottom of the second side plate 31 into the groove 24 opened on one side of the first side plate 21, the elastic shafts 33 are compressed by the first spring 34, causing the elastic shafts 33 to slide into the rotating part 32. Then, the elastic shafts 33 drive the second side plate 31 to slide into the mounting groove 11. The elastic shafts 33 lose their compressive force and reset, rotating and connecting with the mounting groove 11, thus completing the installation of the second side plate 31. Then, the first mounting piece 41 is inserted into the second adjustment groove 23 and then moved downwards to achieve engagement with the first side plate 21. At the same time, the connecting rod 4... 3. The second mounting piece 42 is moved down and engages with the base plate 1 with the locking block 14. Then, the second buckle 28 is inserted into the second adjustment groove 23 and the first mounting piece 41 is inserted into the part of the first mounting piece 41 located in the second adjustment groove 23 to fix the first mounting piece 41. Then, the reverse rotation drive 46 can drive the abutment adjustment piece 47 to move and squeeze the abutment support piece 44. As the abutment support piece 44 slides toward the second side plate 31 and abuts against it, the compressive strength of the second side plate 31 is improved when processing concrete square piles. The top fixing piece 5 further improves the compressive strength of the second side plate 31. The first side plate 21, the second side plate 31 and the bottom plate 1 cooperate to form a processing mold. Then, the pre-tensioned steel bars can be placed inside the mold, and then the concrete can be poured. After the concrete square pile is formed, the top fixing member 5 can be released from the upper end of the second side plate 31. At the same time, the forward rotation drive member 46 drives the abutment adjustment member 47 to move upward and disengage from the abutment connection with the abutment support member 44. At the same time, when the abutment support member 44 loses the squeezing force, it will reset and slide under the action of the elastic member 45. Then, by rotating the second side plate 31, it can be separated from the concrete square pile, and the concrete square pile can be transported by external equipment. Next, when it is necessary to disassemble the mold model, by applying pressure to the unlocking part 35, the unlocking part 35 compresses the second spring 37 and drives the abutment rod 36 to slide inside the base plate 1. Then, the abutment rod 36 contacts the elastic rotating shaft 33 and applies pressure to it, causing it to compress the first spring 34 and slide into the rotating part 32. Then, the second side plate 31 can be slid out in conjunction with the sliding groove 24, thus realizing the disassembly of the second side plate 31. Then, by pulling out the second buckle 28, the fixation between the first mounting part 41 and the first side plate 21 is released. Then, the first mounting part 41 is moved upward and can be taken out from inside the second adjustment groove 23. At the same time, as the first mounting part 41 moves upward, the second mounting part 42 also moves upward and slides to the upper end of the locking block 14 to release the locking between it and the base plate 1. Then, by pulling out the first buckle 27, the fixation between the first side plate 21 and the base plate 1 can be released. Then, the locking part 25 is adjusted into the first adjustment groove 22 for storage, thus allowing the first side plate 21 to be disassembled.
