Description

Technical Field

[0001] The invention relates to the technical field of precast pile grouting equipment, and in particular to a precast pile grouting pile forming device and a composite process. Background Art

[0002] Precast piles are piles made of various materials and various forms (such as wooden piles, concrete square piles, prestressed concrete pipe piles, steel piles, etc.) in factories or construction sites. The piles are driven, pressed or vibrated into the soil using pile sinking equipment. The precast piles used more frequently in China's construction field are mainly precast concrete piles and steel piles. The length of the precast piles used will vary according to different usage conditions and construction requirements. In order to facilitate the production and transportation of precast piles, precast piles with a length greater than ten meters will be grouted at the construction site, while precast piles with a length less than ten meters will be grouted inside the precast pile production factory. When needed, the precast piles will be transported to the designated construction site.

[0003] When concrete grouting is performed on shorter precast piles, the production process of the precast piles is relatively complicated. It is necessary to straighten the steel skeleton first, and bundle and weld several steel skeletons with steel wires, and then wrap the bundled steel skeletons with upper and lower molds, and then grout concrete into the mold. When in use, it takes up a large area and requires the use of multiple processing equipment with different functions. When in use, it is impossible to straighten the steel skeleton, bundle and weld the steel wires, seal the external protection of the steel skeleton, and grout concrete at the same time, resulting in low production efficiency of the precast piles. At the same time, the mold used is large in size and difficult to demould. When precast piles of different lengths need to be formed, the mold of the used length needs to be replaced, and the mold length cannot be adjusted according to the usage during use.

[0014] Preferably, a base is installed under the molding tank, and a plurality of support plates are installed on the top of the base, wherein the top end of one support plate is interconnected with the bottom of the outer wall of the support tube, and the top ends of the remaining support plates are installed on the bottom of the outer wall of the molding tank.

[0015] The composite process of the prefabricated pile grouting pile forming device in the present invention comprises the following steps:

[0016] Step 1: The staff places one of the movable plates to be used inside the forming tank, and passes one end of several steel bar skeletons through the fixing holes on the fixing plate and installs them inside the connecting holes on the side of the movable plate;

[0017] Step 2: The staff pushes the external steel frame to move the steel frame toward the inside of the molding tank, and the steel frame pushes the movable plate to move inside the molding tank. When the movable plate moves to the end of the mounting hole close to the inside of the molding tank, the staff passes one end of the protective plate group through the mounting hole close to the fixed ring position into the inside of the molding tank, and connects it to the connecting block on the side of the movable plate;

[0018] Step 3: When the steel bar skeleton moves, the electric roller on the fixed plate can straighten the bent steel bar skeleton, and at the same time, the electric slider drives the wire drum and the mounting plate to rotate. The mounting plate pulls the steel wire on the wire drum through the connecting hole thereon, and makes the steel wire wind around several steel bar skeletons inside the forming tank as the mounting plate rotates, and the welding head welds the connection position between the steel wire and the steel bar skeleton;

[0019] Step 4: When the steel skeleton pushes the movable plate to move to the bottom of the installation hole near the placement slot, as the movable plate moves, several protective plate groups pulled to the inside of the molding tank cooperate with each other to form a U-shaped protective shell. The staff casts concrete into the U-shaped protective shell through the feed port. When the movable plate moves to the position where the molding tank is located at one end of the placement slot, the protective plate group that enters the molding tank through the uppermost installation hole cooperates with the other protective plate groups to form a cylindrical protective shell and seal the concrete inside it.

[0020] Step 5: The staff places a rolling rack on the ground at one end of the molding tank close to the placement groove. When the formed protective shell is moved out of the molding tank, it is directly moved to the rolling rack, and a moving plate is installed on the end of the protective plate group close to the molding tank. The staff can drive the protective shell and the concrete inside it to rotate through the rolling rack, and the concrete inside the protective shell is formed by the centrifugal force during rotation.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The mold for grouting precast piles in the present invention is composed of a plurality of protective plate groups, and the protective plate group is formed by a plurality of protective plates rotatably connected to each other. When the staff needs to demould the precast piles, the staff connects the external pulling equipment with one end of the protective plate group, and pulls the protective plate group on the outer wall of the precast pile to gradually separate the protective plate group from the surface of the precast pile, thereby achieving the effect of demoulding the precast piles. When the staff needs to store the protective plate group, the plurality of protective plates of the protective plate group can be wound around, and the protective plate group can be stored after being coiled up. There is no need to use a mold when grouting the precast piles, and it is more convenient to demould the protective plate group, and it is convenient for the staff to store the protective plate group. When the staff needs to grout precast piles of different lengths, the staff can rotatably connect the plurality of protective plates according to different usage conditions, so that the staff can form protective plate groups of different lengths for use.

[0023] When the present invention is in use, the staff can straighten and transport the steel skeleton at the same time, and when the steel skeleton is transported, the protective shell formed by the plurality of protective plate groups for grouting can be moved by pushing the movable plate, and when the protective shell moves, the plurality of protective plate groups can be pulled, so that when the movable plate and the steel skeleton are moving, the plurality of protective plate groups will wrap the plurality of steel skeletons as the steel skeleton and the movable plate move, and at the same time as the plurality of protective plate groups wrap the steel skeleton, the feed port can pour concrete into the wrapped steel skeleton, and at the same time, when the steel skeleton moves, the mounting plate can wind and install the steel wire on the steel skeleton according to the movement of the steel skeleton, and weld the connection position between the steel wire and the steel skeleton, which can make the steel skeleton more stable when in use, and can straighten the steel skeleton while the steel skeleton moves, wind and weld the steel wire, and install the protective plate group and fill with concrete at the same time.

[0024] In the present invention, the installation hole at the top is located at the end of the top of the molding tank away from the wire disc, and the remaining installation holes are located on the side of the fixing ring. Therefore, when the installation holes located on the side of the fixing ring transport several protective plate groups to the inside of the molding tank to form a U-shaped protective shell, the staff will grout the inside of the protective shell with concrete. When the concrete inside the U-shaped protective shell is filled, the protective plate group to be used outside will be installed through the top installation hole as the U-shaped protective shell and the steel frame move, and the top of the U-shaped protective shell filled with concrete is sealed, so that several protective plate groups are matched and are collectively called a cylindrical protective shell. The concrete inside the protective shell can be sealed when in use.

[0025] In the present invention, the staff can selectively install and use the support tube according to the shape of the steel bar skeleton used. When the steel bar skeleton used is not bent, there is no need to install and use the support tube. When the steel bar skeleton is bent, the staff will install the support tube at one end close to the wire reel, and drive the steel bar skeleton to be transported through the electric roller inside the fixing hole on the side of the fixing plate, and straighten the steel bar skeleton at the same time.

[0046] The composite process of the prefabricated pile grouting pile forming device in the present invention comprises the following steps:

[0047] Step 1: The staff places one of the movable plates 16 to be used inside the forming tank 1, and passes one end of a plurality of steel bar skeletons through the fixing hole 29 on the fixing plate 4 and installs them inside the connecting hole 21 on the side of the movable plate 16;

[0048] Step 2: The staff pushes the external steel frame to move the steel frame toward the inside of the molding tank 1, and the steel frame pushes the movable plate 16 to move inside the molding tank 1. When the movable plate 16 moves to the end of the mounting hole 11 close to the inside of the molding tank 1, the staff passes one end of the protective plate group 12 through the mounting hole 11 close to the position of the fixing ring 3 to the inside of the molding tank 1, and connects it to the connecting block 20 on the side of the movable plate 16;

[0049] Step 3: When the steel bar skeleton moves, the electric roller 28 on the fixing plate 4 can straighten the bent steel bar skeleton, and at the same time, the electric slider 22 drives the steel wire disc 15 and the mounting plate 24 to rotate, and the mounting plate 24 pulls the steel wire on the steel wire disc 15 through the connecting hole 26 thereon, and makes the steel wire be wound around several steel bar skeletons inside the molding tank 1 as the mounting plate 24 rotates, and the welding head 25 welds the connection position between the steel wire and the steel bar skeleton;

[0050] Step 4: When the steel skeleton pushes the movable plate 16 to move to the bottom of the mounting hole 11 near the placement slot 7, the movable plate 16 moves to pull the plurality of protective plate groups 12 inside the molding tank 1 to cooperate with each other to form a U-shaped protective shell. The staff casts concrete into the U-shaped protective shell through the feed port 10. When the movable plate 16 moves to the molding tank 1 at one end of the placement slot 7, the protective plate group 12 that enters the molding tank 1 through the uppermost mounting hole 11 cooperates with the other protective plate groups 12 to form a cylindrical protective shell and seal the concrete inside it.

[0051] Step 5: The staff places a rolling rack on the ground at one end of the molding tank 1 close to the placement groove 7. When the formed protective shell is moved out of the molding tank 1, it is directly moved to the rolling rack, and a movable plate 16 is installed on the end of the protective plate group 12 close to the molding tank 1. The staff can drive the protective shell and the concrete inside it to rotate through the rolling rack, and the concrete inside the protective shell is formed by the centrifugal force during rotation.

[0052] Please refer to Figure 1 , Figure 3 and Figure 7 When the present invention is used, the staff winds the steel wire to be used on the steel wire disc 15, and connects one end of the steel wire to the mounting plate 24 through the connecting hole 26. The staff can selectively install and use the support tube 2 according to the shape of the steel skeleton used. When the steel skeleton used is not bent, there is no need to install and use the support tube 2. When the steel skeleton is bent, the staff installs the support tube 2 at one end close to the steel wire disc 15, and when in use, the bottom end of the outer wall of the support tube 2 is connected to one of the support plates 5, and the molded tank 1 and the support tube 2 are supported and the position is limited by the support plate 5, so that the support tube 2 and the molded tank 1 are more stable when in use.

[0053] Please refer to Figure 1 , Figure 4 and Figure 8 , the staff inserts one end of several steel skeletons into several fixing holes 29 on the side of the fixing plate 4, and the steel skeleton is located between the two electric rollers 28 in the fixing hole 29. When in use, the two electric rollers 28 can better clamp and position the steel skeleton, and the two electric rollers 28 are respectively located at both ends of the fixing hole 29. When in use, a certain distance is left between the fixing plate 4 and the support tube 2, and the staff can place the movable plate 16 to be used inside the molding tank 1 through the position between the support tube 2 and the fixing plate 4. After one end of several steel skeletons passes through the fixing hole 29 on the side of the fixing plate 4, the end of several steel skeletons close to the molding tank 1 can be installed in the several connecting holes 21 on the side of the movable plate 16. When in use, the movable plate 16 can better support one end of the steel skeleton, and at the same time, it can better seal the two ends of the prefabricated pile when grouting.

[0054] Please refer to Figure 3 , Figure 4 , Figure 7 and Figure 8When in use, the electric roller 28 can rotate inside the fixing hole 29, and when the electric roller 28 rotates, it can drive several steel skeletons to move inside the molding tank 1, and at the same time, the steel skeleton pushes the moving plate 16 to move inside the molding tank 1. When the steel skeleton moves to the inside of the molding tank 1, the staff winds the steel wire near one end of the mounting plate 24 around one of the steel metal skeletons, and drives the steel wire disc 15 to rotate inside the mounting groove 19 through the electric slider 22, and at the same time, the steel wire disc 15 drives the mounting plate 24 to slide along the inner wall of the molding tank 1 through the limit plate 23. During use, as the wire disc 15 and the mounting plate 24 rotate, the mounting plate 24 can wind the steel wire around and mount it on a plurality of steel skeletons when the steel skeletons move inside the molding tank 1. At the same time, when in use, the two welding heads 25 located on the inner wall of the mounting plate 24 can weld the connection positions of the two sides of the steel wire and the steel skeleton when the steel wire contacts the steel skeleton. When in use, the steel wire and the steel skeleton can be connected and fixed in position better, making the plurality of steel skeletons more stable during use.

[0055] Please refer to Figure 3 and Figure 4 When the movable plate 16 moves to the position near the mounting hole 11 inside the molding tank 1, the staff inserts several protective plate groups 12 into the limiting groove 14 on the fixing ring 3 respectively. When in use, the inner wall of the limiting groove 14 cooperates with the limiting rod 17, which can play a better role in limiting the position of the protective plate group 12, so that the protective plate group 12 is more stable when being transported to the inside of the molding tank 1, and the transport position is more accurate, so that several protective plate groups 12 can cooperate with each other. When in use, one end of the protective plate group 12 passes through the mounting hole 11 and is connected to the connecting block 20 on the side of the movable plate 16. As the steel frame pushes the movable plate 16 to move inside the molding tank 1, the movable plate 16 can pull several protective plate groups 12, so that the protective plate groups 12 gradually move into the inside of the molding tank 1, and when the protective plate group 12 moves to the inside of the molding tank 1, the opposite surfaces of several protective plate groups 12 can abut against each other.

[0056] Please refer to Figure 3When in use, the installation hole 11 at the top is located at the end of the top of the molding tank 1 away from the wire disc 15. Therefore, when the installation hole 11 located on the side of the fixing ring 3 transports several protective plate groups 12 to the interior of the molding tank 1 and abuts against each other to seal, several protective plate groups 12 can form a U-shaped protective shell, which is convenient for the staff to grout the interior of the protective shell when in use, and several steel bar skeletons and the steel wires wound and installed on their surfaces are located inside the U-shaped protective shell near the inner wall when in use. When the protective plate group 12 forming the U-shaped protective shell moves to the bottom of the feed port 10, the staff can connect the feed port 10 with the external concrete delivery pipe, so that the concrete is transported to the interior of the molding tank 1 through the feed port 10, and poured into the interior of the protective shell through the top of the U-shaped protective shell.

[0057] Please refer to Figure 3 and Figure 4 After the concrete is poured into the protective shell, the concrete, the protective shell, the movable plate 16 and the steel skeleton can be continuously and slowly moved in the direction away from the wire disc 15, so that the staff can quantitatively pour concrete into the U-shaped protective shell through the feed port 10. When the movable plate 16 moves to the position of the top mounting hole 11, the staff inserts one end of the external protective plate group 12 to be used into the molding tank 1 through the mounting hole 11, and connects it with the top connecting block 20 on the side of the movable plate 16. With the movement of the movable plate 16 and the pulling of several protective plate groups 12, several protective plate groups 12 can be abutted against each other, so that several protective plate groups 12 form a cylindrical protective shell. When the protective shell is in the position after the concrete is poured, the protective plate group 12 seals the top of the U-shaped protective shell through the top mounting hole 11, so that the poured concrete is located inside the cylindrical protective shell.

[0058] Please refer to Figure 3 When in use, the protective plate group 12 is formed by a plurality of protective plates rotatably connected to each other, and the opposite surfaces of two adjacent protective plates in the same protective plate group 12 close to the inner wall of the molding tank 1 are rotatably connected to each other, and the opposite surfaces of two adjacent protective plates away from the inner wall of the molding tank 1 abut against each other, so as to prevent the concrete inside the protective shell from colliding to the outside when in use, causing the protective plate group 12 to bulge away from the steel frame. When in use, when the concrete pushes the protective plate group 12, the opposite surfaces of adjacent protective plates can abut and squeeze each other. When in use, the thrust of the concrete toward the protective plate group 12 can make the adjacent protective plates abut against each other with greater force, so the inside of the protective shell can be sealed.

[0059] Please refer to Figure 1 and Figure 3When the movable plate 16 and the steel bar skeleton move out of the molding tank 1 away from one end of the support tube 2, the staff can push the tie belt 8 inside the placement groove 7. When in use, the inner wall diameter of the placement groove 7 is larger than the inner diameter of the molding tank 1, so when the staff pushes the tie belt 8 to move to the outside of the cylindrical protective shell formed by several protective plate groups 12, the tie belt 8 is too loose outside the protective shell, and the staff can adjust the position of the tie belt 8 on the outer wall of the protective shell according to the use situation. When the staff has adjusted the position of the tie belt 8, the staff can pull the two ends of the tie belt 8 and move the fixing buckle 9 thereon toward the direction of the protective shell. When in use, the fixing buckle 9 can adjust the tightness of the tie belt 8 wrapped around the outer wall of the protective shell, so that the tie belt 8 can fix the position of several protective plate groups 12, making the protective plate groups 12 more stable when in use, which is convenient for the staff to centrifugally shape the prefabricated piles.

[0060] Please refer to Figure 1 and Figure 3 When in use, the staff can place the rolling frame to be used on the ground at one end of the molding tank 1 away from the support tube 2, and the staff can place the movable plate 16 on the rolling frame, and with the movement of the steel frame and the movable plate 16, the protective shell and the steel frame are completely moved to the rolling frame, and when the end of the steel frame away from the movable plate 16 moves out of the molding tank 1, the staff can install and connect the ends of several steel frame close to the molding tank 1 through the remaining movable plates 16 outside, and at the same time, the ends of several protective plate groups 12 close to the support tube 2 are connected to the movable plate 16. When in use, the two movable plates 16 can seal the two ends of the protective shell, and at the same time support and limit the position of the two ends of the steel frame.

[0061] Please refer to Figure 3When the protective shell, the steel frame and the two movable plates 16 are all moved onto the rolling frame, the staff can drive the protective shell to rotate rapidly through the rolling frame, so that the concrete inside the protective shell moves toward the inner wall of the protective shell through the centrifugal force during rotation, until the concrete is formed inside the protective shell. When the concrete is formed and solidified, it can become a precast pile. The staff can disassemble one of the movable plates 16, and the staff can connect the external towing equipment to one end of the protective plate group 12, and pull the protective plate group 12 on the outer wall of the precast pile to gradually separate the protective plate group 12 from the surface of the precast pile. When in use, because the protective shell is formed by a plurality of protective plate groups 12 cooperating with each other, and the protective plate group 12 is formed by a plurality of protective plates rotating and connecting with each other, when the staff disassembles and demoulds the protective plate group 12, a plurality of protective plates can be moved out of the precast pile. At the same time, when the staff needs to store the protective plate group 12, several protective plates of the protective plate group 12 can be wound up, and the protective plate group 12 can be stored after being coiled up. There is no need to use a mold when grouting the prefabricated piles, and it is more convenient to demould the protective plate group 12, and it is convenient for the staff to store the protective plate group 12. When the staff needs to grout prefabricated piles of different lengths, the staff can rotate and connect several protective plates according to different usage conditions, which is convenient for the staff to form protective plate groups 12 of different lengths for use.
