Description

Technical Field

[0001] This utility model relates to a standardized jig for use in cast-in-place pile reinforcement cages. Background Technology

[0002] Pile foundations are a type of building foundation used to enhance the bearing capacity of the ground. Modern buildings often require multiple piles to form a pile group foundation. Among these, bored cast-in-place piles are a widely used type of pile foundation. Cast-in-place piles typically involve drilling holes in the ground, cleaning the holes, inserting a reinforcing cage, and then grouting concrete. The reinforcing cage includes longitudinal main bars and transverse stirrups. Tying the reinforcing cage requires supporting tools, specifically a standardized jig. Chinese patent CN116967377A discloses a standardized jig for cast-in-place piles. In this patent document, the two ends of the reinforcing cage are supported on the jig body, while the middle is supported by an auxiliary plate. The auxiliary plate supports the bottom of the reinforcing cage, but the upper main bars are not supported. When the cast-in-place pile is long, the main bars are also long. When the main bars are connected to the jig body, due to their large self-weight, the middle of the main bars sags, affecting the accuracy of the main bar shaping and the difficulty of the tying work. Utility Model Content

[0003] To address the above shortcomings, the purpose of this utility model is to provide a standardized support frame that can support the main reinforcing bars in the middle of the steel cage.

[0004] Therefore, this utility model provides a standardized jig for cast-in-place pile reinforcement cages, including a jig body, with the two ends of the main reinforcement bars of the reinforcement cage supported on the jig body, and also including a main reinforcement support frame, which is disposed between the jig bodies. The main reinforcement support frame has a support part corresponding to each main reinforcement bar and is used to support the main reinforcement bar. The support part is movable and / or rotated to detach from the reinforcement cage.

[0005] Furthermore, the tire frame body is fixed to the sleeve, the sleeve is detachably fixed to the base frame, and the support frame is detachably fixed to a predetermined position on the base frame.

[0006] Furthermore, the support includes an adjustable support connected to a support rod, which is connected to a support frame. The support rod can adjust the distance between the adjustable support and the reinforcing cage, and when the adjustable support supports the main reinforcement bars of the reinforcing cage, the support rod is fixed to the support frame.

[0007] Furthermore, the adjustable support can rotate under the drive of the support rod. When the adjustable support rotates to a predetermined angle, the side of the adjustable support that is opposite to the main reinforcement of the steel cage will disengage, and the support rod can move and disengage from the steel cage.

[0008] Furthermore, the adjustable support includes an L-shaped bottom and a baffle fixed to the bottom, the baffle being selectively fixed at different positions on the base plate to accommodate main reinforcement bars of different diameters.

[0009] Furthermore, the bottom section is rectangular. When the baffle is in the vertical position, the height of the bottom is greater than its width. In this way, when the bottom is rotated 90°, the adjustable support part is separated from the main reinforcement corresponding to the steel cage.

[0010] The bottom bends laterally to one side in such a way that when the bottom rotates 90°, the adjustable support detaches from the main reinforcement corresponding to the steel cage.

[0011] Furthermore, the upper part of the support frame is open for lifting the steel cage, and support blocks are set on both sides of the support frame. The support blocks have corresponding square holes that mate with square tubes. The square tubes have internal threads, and the support rods have external threads that mate with the internal threads of the square tubes for threaded connection. The bottom of the square tubes is fixed to the support frame.

[0012] Furthermore, the support portion also includes a fixed support portion, and the support frame includes a U-shaped frame, with the fixed support portion located at the bottom of the groove of the U-shaped frame.

[0013] The beneficial technical effects of this utility model are as follows:

[0014] This utility model discloses a standardized jig for cast-in-place pile reinforcement cages. The jig body is used for positioning, and the two ends of the main reinforcement bars and the middle of the main reinforcement bars are supported by a main reinforcement support frame. The main reinforcement support frame has a support part corresponding to each main reinforcement bar and is used to support the main reinforcement bars. The support part can move and rotate. After the reinforcement cage is tied, the main reinforcement bars, stirrups and other connected reinforcement bars form a whole. Then the support part is detached from the reinforcement cage. This not only ensures the support and positioning of all main reinforcement bars during the tying process, but also facilitates the detachment of the reinforcement bars from the reinforcement cage after the reinforcement bars are tied for lifting the reinforcement cage.

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Reference Figures 1 to 4 As shown, this utility model discloses a standardized jig for reinforced concrete piles, comprising a jig body 3 with multiple holes for the main reinforcing bars 4 to pass through. The two ends of the main reinforcing bars 4 are supported on the jig body 3. The jig body 3 is fixed to a sleeve 2, which is connected to a base frame 1. Multiple holes are provided on the base frame 1, and the sleeve is fixed to suitable holes using bolts according to the length of the main reinforcing bars 4. After the reinforced concrete pile is tied, the bolts are removed, and the jig body 3 is separated from the reinforced concrete pile. Several main reinforcing bar support frames 7 are evenly spaced on the base frame 1 between the jig body 3s. The main reinforcing bar support frames 7 can be fixed to the base frame 1 with bolts, or corresponding tracks can be provided on the base frame 1 to facilitate movement and fixation of the main reinforcing bar support frames 7 along the tracks. Each main reinforcing bar support frame 7 has a support part corresponding to a main reinforcing bar 4, which positions and supports the main reinforcing bar 4. During the construction of the reinforcing cage, the main reinforcing bars are usually placed first. At this time, the main reinforcing bars are independent single bars and have not yet been fixed to the stirrups. They are only connected at both ends. The middle of the main reinforcing bars is prone to bending and sagging. In this embodiment, the main reinforcing bar support frame 7 supports and positions each main reinforcing bar. The support part can move and / or rotate. After the reinforcing cage is tied, the support part rotates and moves to detach from the reinforcing cage, so that the reinforcing cage can be lifted smoothly.

[0022] In the above embodiments, reference is made to Figure 2 As shown, the support includes an adjustable support 5 connected to the support rod 8. The adjustable support 5 has a U-shaped structure and includes a U-shaped groove in the middle. The U-shaped groove is used to position and support the main reinforcement 4, and the upper part of the U-shaped groove is open to allow the main reinforcement 4 to be separated from the adjustable support 5. The bottom 501 of the adjustable support 5 can be integrally formed into an L-shape, forming the outer groove wall of the U-shaped groove. The inner groove wall includes a baffle 502, which can be detachably connected to the bottom 501 via flaps and bolts to accommodate different diameters of the main reinforcement 4. For most construction sites, the same standard is generally used for the cast-in-place piles, so the diameter of their main reinforcement 4 is generally the same, and welding the baffle 502 to the bottom 501 is also feasible. (Refer to...) Figure 2 and Figure 3As shown, the support rod 8 is provided with external threads and is threadedly connected to the square tube 9, which is provided with internal threads. Support blocks are provided on both sides of the main reinforcement support frame 7. The support blocks are provided with wing plates, and the wing plates are fixed to the base frame 1 with bolts. The support blocks are provided with holes that mate with the square tube 9. When the main reinforcement 4 is placed on the adjustable support part 5, the square tube 9 can restrict the rotation of the support rod 8. The tail end of the square tube 9 is connected to the tail plate 10, and the tail plate 10 is fixed to the support block with bolts 11. After the reinforcement cage is tied, the bolts 11 on the tail plate 10 are loosened, and the support rod 8 is rotated so that the baffle 502 of the adjustable support part 5 faces the horizontal direction, that is, rotated 90°. The square tube 9 and the support rod 8 are pulled outward together, and the adjustable support part 5 is separated from the reinforcement cage. Since the main reinforcement 4, stirrups and other reinforcements are shaped and formed as a whole after the reinforcement is tied, in some cases, a plug mold can be placed inside the reinforcement cage. At this time, removing the support for the main reinforcement 4 will not cause significant deformation of the reinforcement cage.

[0023] In the above embodiment, the adjustable support 5 can rotate under the drive of the support rod 8. When the adjustable support 5 rotates by a predetermined angle (90° in this embodiment), the side of the adjustable support 5 opposite to the main reinforcement 4 of the steel cage disengages from contact, and the support rod 8 can move and disengage from the steel cage. Specifically, the bottom 501 has a rectangular cross-section, but it can also be other shapes, such as an ellipse. When the baffle 502 is in a vertical position (the adjustable support corresponds to the state of supporting the main reinforcement 4), the height of the bottom 501 is greater than its width. In this way, when the bottom 501 rotates 90°, its width direction is opposite to the main reinforcement 4. After the steel cage is formed, the deformation of the steel cage is small in a short time. Because the width is smaller than the height, the surface corresponding to the adjustable support 5 disengages from the main reinforcement 4, thereby facilitating the outward movement of the support rod 8. (Refer to...) Figure 4 As shown, in Embodiment 2, the bottom 501 bends to one side in the lateral direction, and the part of the bottom 501 used to support the main reinforcement 4 bends and shifts to one side. In this way, when the bottom 501 rotates 90°, the baffle 502 of the adjustable support part 5 rotates to the bottom and disengages from the main reinforcement 4 corresponding to the steel cage.

[0024] In the above embodiments, reference is made to Figure 2 As shown, the support also includes a fixed support 6, and the main rib support frame 7 includes a U-shaped frame. The fixed support 6 includes a groove provided at the bottom 501 of the U-shaped frame. The groove is rectangular or semi-circular in shape and its size is adapted to the main rib 4.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
