Description

Technical Field

[0001] This utility model relates to the field of screw-type cast-in-place pile technology, specifically a screw-type cast-in-place pile body reinforcement structure component. Background Technology

[0002] The screw-type cast-in-place pile is a type of concrete cast-in-place pile with a variable cross-section structure. Its unique pile body design consists of an upper cylindrical straight rod section and a lower threaded screw section. The diameter of the straight rod section is the same as the outer diameter of the screw section, and the length can be adjusted according to geological conditions. It combines the characteristics of straight rod sections and threaded sections, and has significant engineering advantages.

[0003] In the prior art, the screw-grouted pile has an internal reinforcement frame structure. The reinforcement frame can enhance the overall strength of the pile body through the combination of main reinforcement bars and stiffening hoops.

[0004] However, the combination of a single main reinforcement bar and stiffening hoops has poor resistance to lateral (transverse) forces and shear forces, which can easily lead to breakage when the frame is subjected to lateral and shear forces.

[0005] Therefore, a screw-driven pile reinforcement structure component is provided to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this invention is to provide a screw-driven pile body reinforcement structure component to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A screw-grouted pile reinforcement structure component includes two reinforcement frames, a connecting frame between the two reinforcement frames, and multiple stiffening hoops in each reinforcement frame. The multiple stiffening hoops are vertically arranged, and multiple main reinforcement bars are fixedly connected to the multiple stiffening hoops. The multiple main reinforcement bars are arranged along the inner circle of the stiffening hoops, and a stabilizing structure is provided on the multiple main reinforcement bars. The stabilizing structure includes spiral hoops and triangular reinforcement bars.

[0009] As a further embodiment of this utility model: wherein the spiral stirrup is spirally wound around the multiple main stirrups, and multiple spiral stirrups are provided, respectively located between the multiple stiffening stirrups.

[0010] As a further improvement of this utility model, each of the multiple stiffening hoops is fixedly connected with a triangular rib, which is located on the inner sidewall of the stiffening hoop.

[0011] As a further embodiment of this utility model: the two connecting frames include two sets of symmetrical fixing rings, and multiple connecting blocks are fixedly connected to the edges of the two sets of symmetrical fixing rings. Each connecting block has a placement groove. The stiffening hoops on the two reinforcing frames are respectively engaged in the placement grooves. A second spiral rod is spirally connected between the two sets of symmetrical connecting blocks.

[0012] As a further embodiment of this utility model: each of the two sets of symmetrical fixing rings has a fixing disc fixedly connected inside, and the two sets of symmetrical fixing discs are spirally connected by a main spiral rod and a first spiral rod.

[0013] As a further embodiment of this utility model: the two reinforcing frames are arranged vertically and are concentric and coaxial, and the upper surface of the reinforcing frames is provided with an epoxy resin coating.

[0014] As a further embodiment of this utility model, nuts are fitted onto both ends of the first spiral rod, the second spiral rod, and the main spiral rod.

[0015] As a further improvement of this utility model, a concrete patty is welded to the tail end of the reinforcing frame.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By setting spiral stirrups on the main reinforcement bars of the reinforcing frame, the spiral stirrups are tightly wrapped around the outside of the main reinforcement bars to form a continuous spiral structure. When subjected to shear force, the spiral stirrups can effectively resist shear failure and improve the overall shear resistance of the reinforcing frame. By setting triangular bars on the stiffening hoops of the reinforcing frame, the triangular bars are arranged in a triangular shape and connected between the main reinforcement bars of the reinforcing frame to form a stable support structure. The presence of triangular bars increases the lateral stiffness of the reinforcing frame, enabling it to better withstand lateral pressure or bending moment. Attached Figure Description

[0024] Please see Figures 1-4 A screw-grouted pile reinforcement structure component includes two reinforcement frames 1, which are vertically arranged and concentric and coaxial. The upper surface of the reinforcement frame 1 is coated with an epoxy resin coating.

[0025] The two reinforcing frames 1 can increase the overall length of the reinforcing frame 1, which is suitable for deeper screw-grouted piles. The epoxy resin coating on the surface provides additional anti-corrosion protection for the reinforcing frame 1 in special environments (such as saline-alkali land or corrosive soil), extending its service life.

[0026] A connecting frame 3 is provided between the two reinforcing frames 1. The reinforcing frame 1 includes multiple stiffening hoops 101, which are vertically arranged. Multiple main bars 102 are fixedly connected to the multiple stiffening hoops 101, and the multiple main bars 102 are arranged along the inner circle of the stiffening hoops 101.

[0027] The stiffening hoop 101 surrounds the outside of the main reinforcement 102, forming the skeleton of the reinforcing frame 1, which enhances the overall structural strength, prevents the main reinforcement 102 from deforming, and improves the bond strength with concrete.

[0028] A stabilizing structure is provided on multiple main reinforcing bars 102. The stabilizing structure includes spiral stirrups 2 and triangular bars 201. The spiral stirrups 2 are spirally wound on multiple main reinforcing bars 102. Multiple spiral stirrups 2 are provided and are located between multiple stiffening stirrups 101. Triangular bars 201 are fixedly connected to each of the multiple stiffening stirrups 101. The triangular bars 201 are located on the inner side wall of the stiffening stirrups 101.

[0029] Among them, by setting spiral stirrups 2 on the main reinforcement 102 on the reinforcing frame 1, the spiral stirrups 2 are tightly wrapped around the outside of the main reinforcement 102 to form a continuous spiral structure. When subjected to shear force, the spiral stirrups 2 can effectively resist shear failure and improve the overall shear resistance of the reinforcing frame 1. By setting triangular ribs 201 on the stiffening hoops 101 on the reinforcing frame 1, the triangular ribs 201 are arranged in a triangular shape and connected between the main reinforcement 102 of the reinforcing frame 1 to form a stable support structure. The presence of triangular ribs 201 increases the lateral stiffness of the reinforcing frame 1, enabling it to better withstand lateral pressure or bending moment.

[0030] Preferably, the two connecting frames 3 include two sets of symmetrical fixing rings 301. Multiple connecting blocks 303 are fixedly connected to the edges of the two sets of symmetrical fixing rings 301. Each connecting block 303 has a placement groove 302. The stiffening hoops 101 on the two reinforcing frames 1 are respectively engaged inside the placement grooves 302. A second spiral rod 307 is spirally connected between the two sets of symmetrical connecting blocks 303. A fixing disc 304 is fixedly connected inside the two sets of symmetrical fixing rings 301. A main spiral rod 305 and a first spiral rod 306 are spirally connected between the two sets of symmetrical fixing discs 304.

[0031] The connecting frame 3 allows the two reinforcing frames 1 to be connected. First, the two reinforcing frames 1 are laid flat and aligned. Then, fixing rings 301 are fitted onto the stiffening hoops 101 at the tail and head ends of the two reinforcing frames 1, respectively, so that the stiffening hoops 101 are located inside the symmetrical placement grooves 302. The fixing rings 301 are positioned on the stiffening hoops 101. Then, the connecting block 303 is connected through the second spiral rod 307, and the fixing plate 304 is connected through the main spiral rod 305 and the first spiral rod 306, so that the two reinforcing frames 1 are connected together by the spiral rods, fixing the position between the two reinforcing frames 1, so that the reinforcing frames 1 are suitable for the pile body of deeper screw-grouted piles.

[0032] Preferably, nuts are fitted at both ends of the first spiral rod 306, the second spiral rod 307, and the main spiral rod 305, and a concrete cake is welded to the tail end of the reinforcing frame 1.

[0033] The nuts provided can tighten the position and angle of the first spiral rod 306, the second spiral rod 307, and the main spiral rod 305 on the fixing ring 301 and the fixing plate 304, so that the first spiral rod 306, the second spiral rod 307, and the main spiral rod 305 will not rotate, thus preventing the spiral rods from becoming loose.

[0034] Specifically, the concrete pawl is placed at the tail end of the reinforcing frame 1. If there are two sets of reinforcing frames 1, the concrete pawl is placed on the tail end of the bottom reinforcing frame 1. The concrete pawl is placed to strengthen the overall self-weight of the reinforcing frame 1. When the reinforcing frame 1 is submerged in the concrete, it may experience a "floating cage" phenomenon, causing the reinforcing frame 1 submerged in the concrete to float up again, thus affecting the construction. By placing the concrete pawl, the weight of the reinforcing frame 1 itself will increase, and the gravity of the concrete will overcome the buoyancy, thereby avoiding the "floating cage" phenomenon of the reinforcing frame 1.

[0035] Working principle: The two reinforcing frames 1 can increase the overall length of the reinforcing frame 1, which is suitable for deeper screw-grouted piles. Spiral hoops 2 are set on the main reinforcement 102 on the reinforcing frame 1. The spiral hoops 2 are tightly wrapped around the outside of the main reinforcement 102 to form a continuous spiral structure. When subjected to shear force, the spiral hoops 2 can effectively resist shear failure and improve the overall shear resistance of the reinforcing frame 1. Triangular ribs 201 are set on the stiffening hoops 101 on the reinforcing frame 1. The triangular ribs 201 are arranged in a triangle and connected between the main reinforcement 102 of the reinforcing frame 1 to form a stable support structure. The presence of triangular ribs 201 increases the lateral stiffness of the reinforcing frame 1, enabling it to better withstand lateral pressure or bending moment.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
