Description

Technical Field

[0001] This application relates to the field of auxiliary structure technology for steel cages, and in particular to a combined pad block for steel cages in pile foundations. Background Technology

[0002] Pile foundations are a common type of foundation widely used in the foundations of public buildings with large-span roof structures, such as bridges, highways, ports, offshore drilling platforms, super high-rise buildings, foundation pits, ground foundations, airports, and stadiums. Currently, during the construction of steel pile foundations, spacers are typically installed on the reinforcing cage to position the protective layer. These spacers are usually closed rings, and traditionally, they are installed before the reinforcing cage is tied. This process can negatively impact the tying of the reinforcing cage and reduce its efficiency.

[0003] Therefore, there is a need for a modular pad for pile foundation steel cages that can be installed after the steel cage is tied. Utility Model Content

[0004] Therefore, it is necessary to provide a combined pad block for pile foundation steel cages, and its specific technical solution is as follows.

[0005] A composite pad for a pile foundation reinforcement cage, comprising: The mortar pad block body has a notch and a first through hole; the notch extends from the outer side of the mortar pad block body to the axis; the first through hole extends along the axial direction of the mortar pad block body. The metal sheet includes a bonding portion and two ends located at both ends of the bonding portion; the bonding portion is bonded to the outer contour surface of the gasket body; the ends are provided with bent positioning protrusions, and the two ends are respectively bonded to the two inner walls of the notch; A filler pin is inserted into the notch, so that the filler pin and the mortar pad block body support form a through hole for the steel bar to pass through; the side wall of the filler pin is provided with a positioning groove for the insertion of the positioning protrusion; the filler pin is also provided with a second through hole extending along the axial direction of the mortar pad block body. Tie the wire through the first and second through holes.

[0006] Specifically, the notch includes a first arc-shaped groove, the axis of which coincides with the axis of the mortar pad block body; the end of the filling pin is provided with a second arc-shaped groove; the first arc-shaped groove and the second arc-shaped groove form a through hole.

[0007] Specifically, the notch includes a first groove and a second groove. The first groove extends outward from the center of the mortar pad block body, and the second groove extends outward from the end of the first groove. The width of the second groove is greater than the width of the first groove. First through holes are provided on both sides of the first groove. The filler pin includes a narrow section and a wide section. The narrow section is inserted into a first slot, and the wide section is inserted into a second slot. The wide section is provided with a second through hole.

[0008] Specifically, the width of the first slot is equal to the diameter of the through hole.

[0009] Specifically, a keyway is provided on the inner wall of the second slot, and an anti-slip key is provided on the outer side of the wide section, with the anti-slip key inserted into the keyway.

[0010] Specifically, the bonding portion protrudes outward from the mortar pad body.

[0011] Specifically, the outer contour of the mortar pad block body is provided with an arc-shaped groove, the fitting part is inserted into the arc-shaped groove, and the thickness of the fitting part is greater than the depth of the arc-shaped groove.

[0012] Beneficial effects: The combined pad block for pile foundation reinforcement cages provided by this utility model allows the mortar pad block body and the filler pin to be assembled after the reinforcement cage is tied. The mortar pad block body and the filler pin are connected by binding wire to form a ring-shaped combined pad block. This allows the pad block to be installed after the reinforcement cage is tied, avoiding any adverse effects on the reinforcement cage tying. When assembling the mortar pad block body and the filler pin, the positioning protrusion on the metal sheet and the positioning groove on the filler pin can be used to temporarily position the mortar pad block body and the filler pin, facilitating the threading of the binding wire. By attaching the metal sheet to the outer contour of the mortar pad block body, the metal sheet contacts the casing and the inner wall of the pile hole when the reinforcement cage is lowered, avoiding large-area damage to the mortar pad block body due to excessive friction and avoiding affecting the accuracy of the protective layer.

[0022] Example Reference Figure 1 As shown, this embodiment provides a combined pad for pile foundation reinforcement cages, including a mortar pad body 1, a metal sheet 2, a gap-filling pin 3, and a binding wire 4.

[0023] Reference Figure 2As shown, the mortar pad body 1 has a notch 11 and a first through hole 12; the notch 11 extends from the outer side of the mortar pad body 1 to the axis; the first through hole 12 extends along the axial direction of the mortar pad body 1. The metal sheet 2 includes a fitting part 21 and two ends 22 located at both ends of the fitting part 21; the fitting part 21 fits against the outer contour surface of the pad body; the ends 22 are provided with bent positioning protrusions 23, and the two ends 22 are respectively fitted against the two inner walls of the notch 11. The positioning protrusions 23 are bent into shape by the metal sheet 2, so they can undergo a certain degree of elastic deformation. It should be noted that in this embodiment, the metal sheet 2 can be placed in a mold so that the metal sheet 2 and the mortar pad body 1 are integrally formed. The metal sheet 2 is attached to the outer contour of the mortar pad body 1, so that when the steel cage is lowered, the metal sheet 2 contacts the casing and the inner wall of the pile hole. Since the metal sheet 2 has stronger anti-friction ability than the mortar pad body 1, it can avoid large-area wear of the pad and avoid affecting the accuracy of the protective layer. The mortar pad body 1 has a similar composition to the concrete material poured into the pile foundation, and retains high adhesion to the concrete after pouring.

[0024] Continue to refer to Figure 1 and Figure 2 As shown, the filler pin 3 is inserted into the notch 11, forming a through hole 5 between the filler pin 3 and the mortar pad body 1 support to accommodate the passing of the reinforcing bar; the side wall of the filler pin 3 is provided with a positioning groove 31 to accommodate the insertion of the positioning protrusion 23; the filler pin 3 is also provided with a second through hole 32 extending along the axial direction of the mortar pad body 1. During the process of inserting the filler pin 3 into the notch 11, the positioning protrusion 23 is squeezed and undergoes elastic deformation until the positioning protrusion 23 is engaged in the positioning groove 31, forming a temporary positioning, which facilitates the wire threading operation of the binding wire 4.

[0025] Continue to refer to Figure 1 As shown, the binding wire 4 passes through the first through hole 12 and the second through hole 32 and is then tied, thereby binding the mortar pad block body 1 and the filling pin 3 into a solid whole.

[0026] This embodiment provides a combined pad for pile foundation reinforcement cages. After the reinforcement cage is tied, the mortar pad body 1 and the filler pin 3 are assembled. The mortar pad body 1 and the filler pin 3 are then connected by binding wire 4 to form a ring-shaped combined pad. This allows the pad to be installed after the reinforcement cage is tied, avoiding any adverse effects on the tying process. During assembly of the mortar pad body 1 and the filler pin 3, the positioning protrusion 23 on the metal sheet 2 engages with the positioning groove 31 on the filler pin 3 to temporarily position the mortar pad body 1 and the filler pin 3, facilitating the threading of the binding wire 4. By attaching the adhesive portion 21 of the metal sheet 2 to the outer contour of the mortar pad body 1, the metal sheet 2 contacts the casing and the inner wall of the pile hole when the reinforcement cage is lowered, preventing large-area damage to the mortar pad body 1 due to excessive friction and avoiding any impact on the accuracy of the protective layer.

[0027] Specifically, continue to refer to Figure 2 As shown, the notch 11 includes a first arc-shaped groove 13, the axis of which coincides with the axis of the mortar pad body 1; the end of the filling pin 3 is provided with a second arc-shaped groove 33; the first arc-shaped groove 13 and the second arc-shaped groove 33 form a through hole 5. After the pad is installed, the reinforcing bar passes through the through hole 5, and the pad can rotate relative to the reinforcing bar.

[0028] Specifically, the notch 11 includes a first slot 14 and a second slot 15. The first slot 14 extends outward from the center of the mortar pad block body 1, and the second slot 15 extends outward from the end of the first slot 14, with the width of the second slot 15 being greater than the width of the first slot 14. First through holes 12 are provided on both sides of the first slot 14. The filler pin 3 includes a narrow section 34 and a wide section 35. The narrow section 34 is inserted into the first slot 14, and the wide section 35 is inserted into the second slot 15. The wide section 35 has a second through hole 32. A total of two first through holes 12 and two second through holes 32 are provided, arranged in a rectangular array to facilitate the threading of the binding wire 4.

[0029] Specifically, the width of the first slot 14 is equal to the diameter of the through hole 5.

[0030] Specifically, a keyway 16 is provided on the inner wall of the second slot 15, and an anti-slip key 36 is provided on the outer side of the wide section 35. The anti-slip key 36 is inserted into the keyway 16. By setting the keyway 16 and the anti-slip key 36, the filling pin 3 can be positioned in the axial direction after being inserted into the notch 11, and the axial constraint of the mortar pad body 1 and the filling pin 3 after combination is also improved.

[0031] Specifically, the fitting part 21 protrudes outward from the mortar pad block body 1. The outer contour of the mortar pad block body 1 is provided with an arc-shaped groove 17, and the fitting part 21 is inserted into the arc-shaped groove 17, with the thickness of the fitting part 21 being greater than the depth of the arc-shaped groove 17. This allows the metal sheet 2 to contact the casing and the inner wall of the pile hole, providing wear protection for the mortar pad block body 1.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0033] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
