Description

Technical Field

[0001] The utility model relates to the technical field of steel bar cages, in particular to a pipe pile steel bar cage. Background Art

[0002] The main function of the steel cage is the same as the stress on the longitudinal steel bars of the column. It mainly plays a tensile role. The compressive strength of concrete is high but the tensile strength is very low. It restrains the concrete of the pile body and enables it to withstand a certain axial tension.

[0003] The pipe pile reinforcement cage has the following disadvantages: 1. The pipe pile reinforcement cage cannot avoid the existing inner support ring being directly welded on the longitudinal reinforcement, causing damage to the longitudinal reinforcement welding part, affecting the strength of the longitudinal reinforcement, and is easily deformed after being impacted during concrete pouring. To this end, we propose a pipe pile reinforcement cage. Utility Model Content

[0004] In view of the problems in the prior art, the utility model provides a pipe pile reinforcement cage, which can avoid the existing inner support ring being directly welded to the longitudinal reinforcement, causing damage to the welding joint of the longitudinal reinforcement and affecting the strength of the longitudinal reinforcement, and is not easily deformed by impact when pouring concrete.

[0005] The utility model solves the technical problem by adopting the following technical solution: a pipe pile steel cage, comprising a steel cage main part, the steel cage main part is composed of longitudinal steel bars, spiral stirrups and inner support rings, the longitudinal steel bars are sleeved with connecting sleeves at equal distances and the inner side of the connecting sleeves is welded with inner support rings;

[0006] A positioning rib is arranged at the axis center of the inner support ring, and a positioning sleeve is sleeved on the positioning rib at equal distances, and a reinforcing support is welded between the positioning sleeve and the inner support ring.

[0007] Furthermore, a protective layer thickness positioning rod is welded on the outer side of the connecting sleeve facing the reinforcing support, and three groups of protective layer thickness positioning rods and reinforcing supports on the same layer are provided.

[0008] Furthermore, a pad is welded to the outer side of the protective layer thickness positioning rod, which effectively prevents the main part of the steel cage from touching the side wall of the pile hole, causing the protective layer thickness of the main part of the steel cage to decrease, affecting the use effect.

[0009] Furthermore, spiral stirrups with a circular cross-section are welded around the outer side of the longitudinal steel bars, and the spiral stirrups connect the longitudinal steel bars into a whole, so that the bearing capacity of the pile body after casting is stronger.

[0010] Furthermore, the diameter of the positioning reinforcement is twice that of the longitudinal reinforcement.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The inner support ring is welded to the connecting sleeve and the connecting sleeve is set on the longitudinal steel bar. The inner support ring is used to play a supporting effect and can avoid the problem that the existing inner support ring is directly welded to the longitudinal steel bar, causing damage to the welding part of the longitudinal steel bar, affecting the strength of the longitudinal steel bar and reducing the overall strength of the steel cage.

[0013] The positioning bars, positioning sleeves and reinforcing braces are used to reinforce the main parts of the overall steel cage, greatly improving the strength and stability, avoiding large impact forces during concrete pouring, which would cause deformation and damage to the pipe pile steel cage and affect the use effect. The protective layer thickness positioning rods and pads are used to effectively prevent the main parts of the steel cage from touching the side walls of the pile hole, causing the protective layer thickness of the main parts of the steel cage to decrease and affect the use effect.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] In order to avoid the existing inner support ring being directly welded to the longitudinal reinforcement, which may cause damage to the longitudinal reinforcement welding part and affect the strength of the longitudinal reinforcement, and it is not easy to be deformed after impact during concrete pouring, such as Figure 1-3 As shown, a pipe pile reinforcement cage includes a reinforcement cage main part 1, the reinforcement cage main part 1 is composed of longitudinal reinforcement 101, spiral stirrups 102 and inner support rings 103, the longitudinal reinforcement 101 is sleeved with connecting sleeves 5 at equal distances, and the inner side of the connecting sleeves 5 is welded with the inner support ring 103;

[0020] A positioning rib 2 is provided at the axis of the inner support ring 103 , and a positioning sleeve 3 is sleeved on the positioning rib 2 at an equal distance, and a reinforcing support 4 is welded between the positioning sleeve 3 and the inner support ring 103 .

[0021] Among them, a protective layer thickness positioning rod 6 is welded on the outer side of the connecting sleeve 5 facing the reinforcing support 4, and three groups of protective layer thickness positioning rods 6 and reinforcing support 4 on the same layer are provided.

[0022] In this embodiment, Figure 1 As shown, the reinforcing brace 4 improves the stability of the main steel cage component 1 and reduces deformation.

[0023] Wherein, a pad 7 is welded to the outer side of the protective layer thickness positioning rod 6 .

[0024] In this embodiment, Figure 1 As shown, the main part 1 of the steel cage is effectively prevented from touching the side wall of the pile hole, causing the thickness of the protective layer of the main part 1 of the steel cage to be reduced, thus affecting the use effect.

[0025] The outer side of the longitudinal steel bar 101 is wrapped and welded with a spiral stirrup 102 with a circular cross section.

[0026] In this embodiment, Figure 1 As shown, the spiral stirrups 102 connect the longitudinal reinforcements 101 into a whole, so that the bearing capacity of the pile body after pouring is stronger.

[0027] The diameter of the positioning rib 2 is specifically twice that of the longitudinal reinforcement 101 .

[0028] In this embodiment, Figure 3 As shown, the strength of the positioning rib 2 is increased, thereby improving the supporting effect.

[0029] It should be noted that the utility model is a pipe pile steel cage. When working, the inner support ring 103 is welded to the connecting sleeve 5 and the connecting sleeve 5 is sleeved on the longitudinal steel bar 101. The inner support ring 103 is used to play a supporting role, and the existing inner support ring 103 can be avoided from being directly welded to the longitudinal steel bar 101, causing damage to the welding part of the longitudinal steel bar 101, affecting the strength of the longitudinal steel bar 101, and reducing the overall strength of the steel cage. The positioning ribs 2, positioning sleeves 3 and reinforcing braces 4 are used to reinforce the overall steel cage main component 1, and the strength and stability are greatly improved, avoiding a large impact force during concrete pouring, causing deformation and damage to the pipe pile steel cage, affecting the use effect, and using the protective layer thickness positioning rod 6 and pad 7 to effectively prevent the steel cage main component 1 from touching the side wall of the pile hole, causing the protective layer thickness of the steel cage main component 1 to be reduced, affecting the use effect.
