Description

Technical Field

[0001] This invention relates to the field of pedestal support construction technology, and more specifically, to a pedestal pre-supported pile mold. Background Technology

[0002] A pedestal support refers to a support erected on a pedestal during casting. Generally, the support is formed by building inner and outer molds on the pedestal and then casting between the molds.

[0003] However, after the existing mold is cast, because the inner mold is located on the inner wall of the support column, it does not have many points of force application. At the same time, the mold is tightly fitted to the inner wall of the support column during the molding process, which makes it difficult to remove the inner mold due to friction. Summary of the Invention

[0004] The purpose of this invention is to provide a pre-supported pile mold for a pedestal, which solves the problem that during the casting of a support column on a pedestal, the inner mold is located on the inner wall of the support column, making it difficult to control the force applied to it and thus difficult to remove it.

[0005] The embodiments of the present invention are achieved through the following technical solutions:

[0006] This invention provides a pre-supported pile mold with a platform, including an excavation hole, a platform at the bottom of the middle of the excavation hole, a platform plate at the top of the platform, reinforcing bars at the top of the platform, an outer mold connected to the top of the platform, an inner mold connected to the middle of the outer mold, a hollow annular groove inside the platform plate, several clamping blocks in the middle of the hollow annular groove, a hinge rod connected to one side of the clamping blocks, and a shrinkage assembly in the middle of the inner mold, which separates and deflects through the shrinkage assembly.

[0007] The hinge rod consists of two rods that are hinged together at one end, and the hinged end of the hinge rod is connected to the clamping block. A spring is installed between the two hinge rods.

[0008] The protruding part of the hinge rod away from the clamping block is set on the side wall of the base plate;

[0009] A semi-circular slot is provided on one side where the two clamping blocks fit together, and the reinforcing bar passes through the slot where the two clamping blocks fit together.

[0010] The shrinkage assembly includes a deflection block, a rotating gear, and a combination block. The deflection block is located on both sides of the center of the inner mold, the rotating gear is located on one side of the deflection block, and the combination block is located around the inner mold.

[0011] The deflection block includes a first fitting block connected to one side of the deflection block, and a combination block connected to the end of the first fitting block that is far away from the deflection block. The end of the deflection block connected to the combination block is slidably connected to the annular groove on the inner wall of the combination block through a hinge shaft. The first fitting block is slidably connected to the slot in the middle of the deflection block. A rack that meshes with the rotating gear is provided on one side of the deflection block.

[0012] Preferably, the inner mold is a cylinder composed of four modular blocks.

[0013] Preferably, the rotating gear includes a sleeve block, which is disposed on one side of the rotating gear and fits against one side of the semi-circular ring of the combination of the first fitting block and the deflection block. The sleeve block is telescopic on both sides, and two combined blocks are connected to each end of the sleeve block.

[0014] Preferably, the assembly block includes a deflection groove, a hinge shaft, a fitting groove, and a second fitting block. The deflection groove is disposed at both ends of the assembly block, the hinge shaft is disposed at one end of the assembly block, the fitting groove is disposed at the end of the assembly block away from the hinge shaft, and the second fitting block is disposed at the end of the adjacent assembly block with the fitting groove away from the hinge shaft.

[0015] Preferably, each pair of assembly blocks is connected to each other at one end by a hinge shaft. The fitting groove is an arc-shaped groove with an inclined inner wall at the end of the assembly block away from the hinge shaft. The second fitting block is a protrusion that mates with the fitting groove, and one end of the second fitting block is set as an arc.

[0016] The technical solutions of the embodiments of the present invention have at least the following advantages and beneficial effects:

[0017] 1. The shrinkage component in this device can partially deflect and shrink the assembled inner mold, thereby allowing the inner mold to undergo certain disassembly and deformation to separate from the inner wall of the cast support, facilitating the demolding of the inner mold.

[0018] 2. The device is also equipped with clamping blocks that can clamp and stabilize the reinforcing bars to a certain extent, so that the reinforcing bars will not tilt due to shaking during the precasting and casting process. Attached Figure Description

Detailed Implementation

[0029] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" 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 this invention based on the specific circumstances.

[0030] The following is combined Figures 1 to 8 The present invention will be described in detail below.

[0031] A pre-supported pile mold includes an excavation hole 1, a base 2 disposed at the bottom center of the excavation hole 1, a base plate 201 disposed at the top of the base 2, reinforcing bars 2011 disposed at the top of the base 2, an outer mold 3 connected to the top of the base 2, an inner mold 4 connected to the center of the outer mold 3, a hollow annular groove 2012 disposed inside the base plate 201, several clamping blocks 2013 disposed in the center of the hollow annular groove 2012, a hinge rod 2014 connected to one side of each clamping block 2013, and a shrinkage assembly disposed in the center of the inner mold 4. The inner mold 4 is separated and deflected by the shrinkage assembly. The hinge rod 2014 consists of two rods that are hinged together at one end. The hinged end of the hinge rod 2014 is connected to the clamping block 2013. A spring is provided between the two hinge rods 2014. The protruding part of the end of the hinge rod 2014 away from the clamping block 2013 is provided on the side wall of the base plate 201. A semi-circular slot is provided on the side where the two clamping blocks 2013 are in contact, and the steel bar 2011 passes through the slot where the two clamping blocks 2013 are in contact.

[0032] First, a hole 1 is dug in the ground, and then a platform 2 is erected inside it. At the same time, steel bars are connected to the platform 2 by passing through the platform plate 201 at the top of the platform 2. Meanwhile, other parts of the steel bars will protrude from the top of the platform plate 201. Then, an outer mold 3 and an inner mold 4 are placed on the platform plate 201. Then, the casting is carried out between the outer mold 3 and the inner mold 4 to form a cylindrical support. At the same time, the steel bars 2011 protruding from the platform plate 201 will be located between the outer mold 3 and the inner mold 4, so that they will be cast together. The steel bars 2011 are cast into the support formed between the outer mold 3 and the inner mold 4 to increase the strength of the support.

[0033] Simultaneously, when the reinforcing bar 2011 passes through the base plate 201, the hinge rod 2014 is pressed and closed, causing it to deflect along the hinge axis at one end. This causes the clamping block 2013 to separate in the hollow annular groove 2012, allowing the reinforcing bar 2011 to pass between the clamping blocks 2013. Then, the hinge rod 2014 is released, allowing it to reset due to the elasticity of the spring. This causes the clamping block 2013 to close and clamp the reinforcing bar 2011 with a certain force through the groove on one side, thereby stabilizing the reinforcing bar 2011.

[0034] Furthermore, the shrinkage assembly includes a deflection block 401, a rotating gear 402, and a combination block 403. The deflection block 401 is disposed on both sides of the middle portion of the inner mold 4, the rotating gear 402 is disposed on one side of the deflection block 401, and the combination block 403 is disposed around the inner mold 4. The inner mold 4 is a cylinder composed of four combination blocks 403 assembled together. The deflection block 401 includes a first fitting block 4011, which is connected to one side of the deflection block 401. The first fitting block 4011 and the deflection block 401 are respectively connected to a combination block 403 at their ends. The first fitting block 4011 is slidably connected in a slot in the middle of the deflection block 401. A rack that meshes with the rotating gear 402 is provided on one side of the first fitting block 4011. The rotating gear 402 includes a sleeve block 4021, which is provided on one side of the rotating gear 402 and fits against the first fitting block 4011 and the deflection block 403. On one side of the semi-circular ring of the deflection block 401 assembly, the sleeve block 4021 is telescopically designed on both sides. Two assembly blocks 403 are connected to both ends of the sleeve block 4021. Each assembly block 403 includes a deflection groove 4031, a hinge shaft 4032, a fitting groove 4033, and a second fitting block 4034. The deflection groove 4031 is located at both ends of the assembly block 403, the hinge shaft 4032 is located at one end of the assembly block 403, and the fitting groove 4033 is located on the assembly block 403 away from the hinge. At one end of shaft 4032, a second fitting block 4034 is disposed at the end of adjacent combination block 403 with fitting groove 4033 away from hinge shaft 4032. Each pair of combination blocks 403 are connected to each other at one end through hinge shaft 4032. Fitting groove 4033 is an arc-shaped groove with an inclined inner wall at the end of combination block 403 away from hinge shaft 4032. The second fitting block 4034 is a protrusion that mates with fitting groove 4033, and one end of the second fitting block 4034 is set as an arc.

[0035] After casting using the outer mold 3 and inner mold 4, when the inner mold 4 needs to be removed, the rotating gear 402 in the inner mold 4 is rotated. When the rotating gear 402 rotates, it meshes with the teeth of the deflection block 401, causing the deflection block 401 to move to one side, thus contracting along the first interlocking block 4011. At the same time, one end of the deflection block 401 connected to the assembly block 403 is slidably connected to the annular groove on the inner wall of the assembly block 403 via a hinge shaft. This allows the deflection block 401 to slide along the groove via the hinge shaft when it causes the assembly block 403 to deflect, thus cooperating with the deflection of the assembly block 403. During contraction, it will cause the connected assembly block 403 to move. The hinge axis 4032 deflects, and when one of the assembly blocks 403 deflects, it will have space to deflect through the deflection groove 4031. When one of the assembly blocks 403 deflects, the second fitting block 4034 at the other end will separate from the fitting groove 4033, thereby separating the assembly block 403 from the cast-in-place column inner wall, so that it can move the other assembly block 403 connected to it, thereby facilitating the separation and removal of part of the inner mold 4. Then, by controlling the other deflection block 401, the other half of the inner mold 4 can be removed, so as to prevent the inner mold from being difficult to remove due to friction with the cast-in-place column inner wall and the inconvenience of applying force.

[0036] The center point of the arc of the deflection block 401 is set with the hinge axis 4032 so that when the deflection block 401 is deflected by the first fitting block 4011, the deflection block 401 will not shift along the contraction of the first fitting block 4011.

[0037] Finally, the rotating rack 402 is attached to one side of the deflection block 401 by the sleeve block 4021. At the same time, the two sides of the sleeve block 4021 are also telescopic, so that the sleeve block 4021 can retract together with the deflection block 401 to allow the combination block 403 to deflect.

[0038] The following is a detailed implementation process of the present invention: First, an excavation hole 1 is dug in the ground. Then, a platform 2 is erected inside it. Reinforcing bars are connected to the platform 2 via a platform plate 201 at the top of the platform 2. Other reinforcing bars protrude from the top of the platform plate 201. Then, an outer mold 3 and an inner mold 4 are placed on the platform plate 201. Casting is then performed between the outer mold 3 and the inner mold 4 to form a cylindrical support. The reinforcing bars 2011 protruding from the platform plate 201 are positioned between the outer mold 3 and the inner mold 4, allowing them to be cast together. The reinforcing bars 2011 are then poured into the outer mold. The strength of the support column formed between mold 3 and inner mold 4 is increased. Simultaneously, when the reinforcing bar 2011 passes through the base plate 201, pressure is applied to the hinge rod 2014 to close it, causing it to deflect along one end of the hinge axis. This causes the clamping block 2013 to separate within the hollow annular groove 2012, allowing the reinforcing bar 2011 to pass between the clamping blocks 2013. Then, the hinge rod 2014 is released, allowing it to reset due to the spring's elasticity. This causes the clamping blocks 2013 to close, applying force to clamp the reinforcing bar 2011 through the groove on one side, thus securing the reinforcing bar 2011. 011 achieves a certain degree of stability. After casting through the outer mold 3 and inner mold 4, when the inner mold 4 needs to be removed, the rotating gear 402 in the inner mold 4 is rotated. When the rotating gear 402 rotates, it meshes with the toothed block of the deflection block 401, causing the deflection block 401 to move to one side, thereby contracting along the first interlocking block 4011. During the contraction, the connected assembly block 403 is deflected along the hinge axis 4032. When one of the assembly blocks 403 deflects, it has space to deflect through the deflection groove 4031. When one of the assembly blocks 403 deflects, the second fitting block 4034 at the other end separates from the fitting groove 4033, thereby separating the assembly block 403 from the cast-in-place column inner wall. This allows space to move the other assembly block 403, making it easier to separate and remove part of the inner mold 4. Then, by controlling the other deflection block 401, the other half of the inner mold 4 can be removed, preventing the inner mold from being difficult to remove due to friction against the cast-in-place column inner wall and the inconvenience of applying force.
