[0002] In building engineering, steel cages are usually used to reinforce concrete structures to ensure the stability and safety of the structures. However, during the construction process, due to the influence of external forces or its own gravity, the steel cage is prone to deformation, which not only affects the construction progress but also may pose a threat to the safety of the building. Most of the existing steel cage support structures on the market adopt a fixed design, which cannot flexibly adapt to steel cages of different sizes and shapes, and the support effect on the steel cage is limited. Summary of the Invention

Detailed implementation manners

[0023] As Figures 1-3 shown in Figures 1-3 , a steel reinforcement cage support structure includes a main rod 1, and telescopic ejector rods 4 are arranged at both ends of the main rod 1. The telescopic ejector rods 4 can be telescopic along the axial direction of the main rod 1;

[0024] A steel bar engaging member 5 is arranged at one end of the telescopic ejector rod 4 away from the main rod 1. The steel bar engaging member 5 is an arc-shaped structural member with an obtuse central angle. An active arc-shaped member 6 that can extend from one end of the steel bar engaging member 5 is arranged inside the steel bar engaging member 5.

[0025] In a preferred solution, threaded inner grooves 2 are arranged at both ends of the main rod 1, and a first external thread section 401 is arranged on the outer wall of the telescopic ejector rod 4. The main rod 1 and the telescopic ejector rod 4 are connected through the threaded fit of the threaded inner groove 2 and the first external thread section 401.

[0026] In a preferred solution, an anti-slip member 3 is arranged at the end of the main rod 1. The anti-slip member 3 is of a cylindrical structure, and a first threaded groove section 301 and a second threaded groove section 302 are arranged inside the anti-slip member 3;

[0027] Second external thread sections 101 are arranged at positions near both ends of the outer wall of the main rod 1;

[0028] The inner diameter of the first threaded groove section 301 is the same as the outer diameter of the main rod 1, and the first threaded groove section 301 is matched with the second external thread section 101;

[0029] The inner diameter of the second threaded groove section 302 is the same as the outer cylinder of the telescopic ejector rod 4, and the second threaded groove section 302 is matched with the first external thread section 401.

[0030] In a preferred solution, an arc-shaped inner groove 501 with one end open is arranged inside the steel bar engaging member 5. The active arc-shaped member 6 is arranged in the arc-shaped inner groove 501. A slotted groove 601 is arranged on the active arc-shaped member 6, and a limiting column 7 is arranged in the arc-shaped inner groove 501. The limiting column 7 is perpendicular to the active arc-shaped member 6 and passes through the slotted groove 601.

[0031] In a preferred solution, a side slotted groove 502 is arranged on the convex arc surface of the steel bar engaging member 5, a tooth groove 8 is arranged on the convex arc surface of the active arc-shaped member 6, and teeth 9 are arranged in the tooth groove 8;

[0032] An adjusting gear 10 is installed on the telescopic ejector rod 4 through a pin shaft. The adjusting gear 10 passes through the side slotted groove 502 and forms a fit with the teeth 9 on the active arc-shaped member 6.

[0033] When the steel reinforcement cage support structure disclosed by the present novelty is used for supporting a steel reinforcement cage:

[0034] As Figure 1, in the initial state of the telescopic push rod 4, it is retracted into the threaded inner groove 2 of the main rod 1. At this time, the length of the entire support structure is less than the diameter of the steel cage. The support structure is placed into the steel cage, and the telescopic push rod 4 is rotated to make it extend relative to the main rod 1 and approach the position of the main reinforcement of the steel cage. After approaching the position of the main reinforcement, the steel bar clamping member 5 is tightened against the steel cage to ensure fit. At this time, the adjusting gear 10 is rotated to make the movable arc member in the steel bar clamping member 5 extend out to realize the circumferential fixation of the main reinforcement of the steel cage. Then the main rod 1 is rotated to make the main rod 1 move relative to a fixed telescopic push rod 4 to the other end until the steel bar clamping member 5 on the other telescopic push rod 4 fits the main reinforcement. After that, the corresponding adjusting gear 10 is rotated to realize the fixation between the two steel bar clamping members 5 and the steel cage on the entire support structure.

[0035] Rotate the anti-slip member 3 to make it close to the main rod 1. After the first thread groove section 301 contacts the second external thread section 101, continue to rotate the anti-slip member 3 to make the anti-slip member 3 as a whole located at the connection position between the main rod 1 and the telescopic push rod 4 to avoid thread slipping.

[0036] After the above operations are completed, the support structure forms a radial support for the steel cage, realizing an effective support for the steel cage, avoiding deformation of the steel cage during construction, and improving the construction efficiency and safety.
