Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a construction structure for anti-tilting positioning of cast-in-place pile reinforcement cages. Background Technology

[0002] Reinforcing cage anti-tilting positioning construction refers to ensuring that the reinforcing cage maintains its designed position during the hoisting, lowering, and concrete pouring stages of concrete cast-in-place pile construction through innovative mechanical structures or construction methods.

[0003] A search revealed Chinese patent CN215716584U, which discloses a positioning device for main reinforcement bars of a steel cage used in building construction to prevent deviation. The device features 24 sets of identical positioning protrusions evenly fixed on the outer sidewall of a positioning plate. Each protrusion has a snap-fit ​​groove, within which a snap-fit ​​block is nested. A connecting rod is fixedly connected to the end of each snap-fit ​​block away from the positioning plate, and a plug-in block is fixedly connected to the other end of the connecting rod. A flexible baffle is fixedly connected to the sidewall of each plug-in block away from the positioning plate, and the plug-in block has a plug-in groove. This allows the positioning protrusions to be divided into two, three, four, six, or eight sets to accommodate different main reinforcement bar spacings, accurately positioning the main reinforcement bars on the same circle and achieving spatial positioning of the reinforcement bars. The number of plug-in blocks can be selected according to specific circumstances during processing. The detachable structure improves both construction efficiency and installation accuracy.

[0004] Based on the above search and existing technology, the following findings were made:

[0005] Existing patents require the simultaneous operation of multiple components, resulting in excessive assembly time and high costs. Changing the configuration requires disassembling and reassembling all components, which is costly. Furthermore, the flexible baffles made of plastic are prone to deformation and cannot effectively maintain the spacing between the main ribs, thus having certain limitations. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model proposes a construction structure for anti-tilting positioning of cast-in-place pile reinforcement cages, which is convenient and practical, easy to process on the construction site, and has low cost.

[0007] The technical solution to achieve the purpose of this utility model is: a construction structure for anti-tilting and positioning of a cast-in-place pile reinforcement cage, including vertical reinforcement bars and pile holes, and further including reinforcing bars and arc-shaped plates.

[0008] The reinforcing bars are welded to the vertical reinforcing bars, and the vertical reinforcing bars and the reinforcing bars together form a reinforcing cage, which is set inside the pile hole;

[0009] Preferably, a pair of the arc-shaped plates are disposed outside the vertical reinforcing bars, and a connecting plate is disposed outside the connection between the pair of arc-shaped plates.

[0010] Preferably, the vertical reinforcing bars are internally fixed with stiffening hoops, and the vertical reinforcing bars are externally fixed with spiral hoops.

[0011] Preferably, a pair of connecting bolts are threaded together between the arc-shaped plate and the connecting plate, and an anchoring bar is fixedly installed at the top of the vertical reinforcing bar, with one end of the anchoring bar abutting against the pile hole.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, this utility model uses continuous winding to create a "spring effect," enhancing the concrete's restraint. The stiffening hoop serves as a rigid frame, controlling the deformation to ≤2mm during hoisting. The curved plate is connected by bolts, allowing for rapid installation.

[0014] Secondly, this utility model achieves dual protection of "anchoring and limiting" through mechanical structure innovation, and has the characteristics of high precision, low cost and rapid construction. It is particularly suitable for the complex working conditions of overseas aid projects. In areas with scarce materials, only conventional steel bar processing equipment is required, without the need for special tools.

[0015] This invention solves the problems of existing patents, which require the simultaneous operation of multiple components, resulting in excessive assembly time; and the need to disassemble and reassemble all components to change configurations, leading to high costs. Furthermore, the use of flexible plastic baffles makes them prone to deformation and cannot effectively maintain the spacing between the main ribs. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an improved anti-tilting positioning construction structure for cast-in-place pile reinforcement cages. The technical solution of this utility model is as follows:

[0025] Example 1

[0026] like Figure 1 As shown, a construction structure for anti-tilting positioning of a cast-in-place pile reinforcement cage includes vertical reinforcing bars 1 and a pile hole 7 to ensure the stability of the reinforcement cage during grouting. It also includes reinforcing bars 4 and an arc-shaped plate 5.

[0027] The reinforcing bar 4 is welded to the vertical reinforcing bar 1. The vertical reinforcing bar 1 and the reinforcing bar 4 together form a reinforcing cage. The reinforcing cage is set inside the pile hole 7 to effectively prevent deformation of the reinforcing cage during hoisting.

[0028] A pair of arc-shaped plates 5 are set outside the vertical steel bars 1, and a connecting plate 501 is set outside the connection of the pair of arc-shaped plates 5. The threaded structure facilitates disassembly and installation, and improves the overall installation speed of the structure.

[0029] Example 2:

[0030] Based on the anti-tilting positioning construction structure for the reinforcing cage of a cast-in-place pile provided in the first embodiment of this application, the second embodiment of this application proposes another anti-tilting positioning construction structure for the reinforcing cage of a cast-in-place pile. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0031] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 2-4 As shown, a stiffening hoop 3 is fixedly installed inside the vertical steel bar 1, and a spiral hoop 2 is fixedly installed outside the vertical steel bar 1. The continuous spiral winding forms a three-dimensional constraint force, which effectively restricts the lateral expansion of concrete and improves the compressive strength of the core concrete. The stiffening hoop 3 also serves as a rigid support skeleton to maintain the accuracy of the main reinforcement spacing.

[0033] Furthermore, a pair of connecting bolts 502 are threaded together between the arc plate 5 and the connecting plate 501. An anchoring steel bar 6 is fixedly installed at the top of the vertical steel bar 1. One end of the anchoring steel bar 6 abuts against the pile hole 7. The arc plate 5 is pressed and fixed to the hole opening by a jack to strengthen the stability of the structure. The anchoring steel bar 6 is bent outward at a certain angle and lowered into the pile hole 7 to prevent the steel cage from tilting or deviating to one side.

[0034] The specific working method is as follows: First, reinforcing bars 4 and stiffening hoops 3 are welded onto the vertical reinforcing bars 1, and spiral hoops 2 are wrapped around the outside to form a composite structure; then, the top anchoring reinforcing bars 6 are pre-bent outward to form a mechanical snap-fit ​​structure; next, the reinforcing cage is lowered and hoisted into the pile hole 7, and the hoisting is stopped when the top of the cage is 1~1.2m away from the hole opening; and the segmented arc plate 5 is wrapped around the outside of the vertical reinforcing bars 1 and fastened by connecting plates 501 and connecting bolts 502. The arc plate 5 is then tightened with a jack to make it fit tightly against the hole wall; finally, the bent end of the anchoring reinforcing bar 6 is locked with the hole wall by friction to prevent horizontal deviation, the radial pressure of the arc plate 5 offsets the impact force of pouring, the continuous winding of the spiral hoops 2 prevents aggregate jamming, and the stiffening hoops 3 maintain the overall rigidity of the reinforcing cage; in addition, the arc plate 5 can be removed and reused after the concrete has initially set, and the anchoring reinforcing bars 6 are permanently embedded in the pile body.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
