Description

Technical Field

[0001] The present invention relates to the technical field of tire racks, and particularly to a surrounding type steel reinforcement cage tire rack. Background Art

[0002] The outer layer of the tower column of a sea area bridge needs to be installed with a steel reinforcement cage to improve its strength. Generally speaking, the tower column has variable cross-section segments and equal cross-section segments. Thus, the inner contour of the cross-section of the steel reinforcement cage of the equal cross-section segment should also be an equal cross-section structure. And based on the fact that epoxy steel bars are generally used as materials to manufacture the steel reinforcement cage for sea area bridges, therefore, it is not suitable to fix adjacent steel bars by welding. As a result, the steel reinforcement cage needs to complete the fixation between adjacent steel bars through a binding connection method. However, the binding connection method often causes the phenomena of steel bar movement and dislocation during the operation process, resulting in insufficient overall strength of the steel reinforcement cage, and further resulting in poor stability of the steel reinforcement cage. Summary of the Invention

[0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a surrounding type steel reinforcement cage tire rack, which can not only complete the fixation of the steel reinforcement cage by binding, but also make the stability of the bound steel reinforcement cage better.

[0004] The purpose of the present invention is achieved by adopting the following technical solutions:

[0005] The surrounding type steel reinforcement cage tire rack includes a frame. The frame extends in the height direction so that the outer contour of the frame is in a rectangular frame structure. Four guide rods extending in the height direction and having a T-shaped cross-section are fixed inside the frame. The four guide rods are symmetrically distributed in pairs about the symmetry axis of the frame. A load-bearing limit plate is fixed at the bottom of the guide rods. It further includes four load-bearing members. The four load-bearing members correspond to the four guide rods one by one. The load-bearing member includes a long strip-shaped socket shell and a long strip-shaped load-bearing plate. The socket shell is provided with a receiving hole extending from the bottom towards the top of itself. An avoidance groove is provided on the side of the socket shell. The receiving hole and the avoidance groove form an avoidance space with a T-shaped structure. The socket shell is sleeved on the guide rod from the top of the guide rod downwards, so that the guide rod is received in the avoidance space and is supported by the load-bearing limit plate. The load-bearing plate is provided with a plurality of grooves. The plurality of grooves are arranged at intervals in the direction of gravity. The grooves are used to receive steel bars to support and limit the steel bars.

[0006] Further, inclined strengthening bars are fixed at the inner four corners of the top of the frame and the inner four corners of the bottom of the frame. The two ends of the guide rod are respectively fixed on two of the inclined strengthening bars.

[0007] Further, the frame is composed of two half frames. The half frames are provided with connecting plates. Two connecting plates belonging to different two half frames are connected by a plurality of screw assemblies.

[0008] Further, a hollow is formed between two connecting plates that belong to the same semi-frame and have overlapping projections to form an anti-interference groove.

[0009] Further, a top cover is fixed to the top of the socket housing, and the top cover is located directly above the guide rod and supported by the guide rod.

[0010] Further, the load-bearing member is made of acrylic material.

[0011] Further, the frame is made of steel material.

[0012] Further, the groove has a semi-circular structure.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The T-shaped guide rod guides and positions the load-bearing plate, thereby preventing the guide plate from moving erratically, enabling the guide plate to stably support the steel bars through its own groove, and making the process of tying galvanized buckles or binding wires relatively stable and reliable. By fixing a load-bearing limit plate at the bottom of the guide rod to support the load-bearing plate through the load-bearing limit plate, the load-bearing plate can stably support the steel cage.

[0027] Unless otherwise defined, all technical terms and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] Referring to Figures 1-9 , the surrounding type steel reinforcement cage jig of a preferred embodiment of the present invention includes a frame 1. Referring to Figure 1 , the frame 1 extends in the height direction so that the outer contour of the frame 1 is in a rectangular frame structure. Four guide rods 11 extending in the height direction and having a T-shaped cross-section are fixed inside the frame 1 (refer to Figure 7 ), the four guide rods 11 are symmetrically distributed in pairs about the symmetry axis of the frame 1, and a load-bearing limit plate 12 is fixed at the bottom of the guide rod 11 (refer to Figure 2 and Figure 6 ). Referring to Figure 1 , Figure 8 and Figure 9, the circumferential steel cage jig also includes four load-bearing members 2, which correspond to the four guide rods 11 one by one. The load-bearing member 2 includes a strip-shaped socket shell 21 and a strip-shaped load-bearing plate 22. The socket shell 21 is provided with a receiving hole 211 extending from the bottom towards the top of itself. An avoidance groove 212 is provided on the side of the socket shell 21. The receiving hole 211 and the avoidance groove 212 form an avoidance space with a T-shaped structure. The socket shell 21 is sleeved on the guide rod 11 from the top of the guide rod 11 downwards, so that the guide rod 11 is received in the avoidance space and is supported by the load-bearing limit plate 12 (see Figure 2 and Figure 6 ). The load-bearing plate 22 is provided with a plurality of grooves 221, and the plurality of grooves 221 are arranged at intervals in the direction of gravity. The grooves 221 are used to receive steel bars to support and limit the steel bars.

[0029] During operation, workers embed the hoop stirrups wound into a ring into a plurality of grooves 221 of the same layer, then penetrate the main bars inside or outside the hoop stirrups. The main bars are in contact with the multiple hoop stirrups, and then the main bars and the hoop stirrups are tied together with galvanized buckles or binding wires. Based on the grooves 221, the hoop stirrups can be prevented from moving, so as to provide a stable working environment for the connection of galvanized buckles or binding wires, making the fixing process of the steel cage relatively stable and reliable, thereby improving its stability after forming.

[0030] Obviously, the T-shaped guide rod 11 guides and limits the load-bearing plate 22, so as to prevent the guide plate from moving, so that the guide plate can stably support the steel bars through its own grooves 221, making the process of tying galvanized buckles or binding wires relatively stable and reliable. By fixing a load-bearing limit plate 12 at the bottom of the guide rod 11, the load-bearing limit plate 12 is used to support the load-bearing plate 22, so that the load-bearing plate 22 can stably support the steel cage.

[0031] Based on the fact that the hoop stirrup has a large elastic potential energy after bending, preferably, see Figure 1 , inclined reinforcing bars 13 are fixed at the inner four corners of the top of the frame 1 and the inner four corners of the bottom of the frame 1. Both ends of the guide rod 11 are respectively fixed on two of the inclined reinforcing bars 13. With this setting, the stress points of the frame 1 are at the corners of the frame 1, and the strength at the corners of the frame 1 is the greatest, thus ensuring that the frame 1 will not fall apart.

[0032] Preferably, see Figure 1, the rack 1 is composed of two half - frames 14. The half - frames 14 are provided with connecting plates 15. Two connecting plates 15 belonging to different half - frames 14 are connected by a plurality of screw assemblies. With this setting, after the binding of the steel reinforcement cage is completed, by loosening the bolt assembly, the steel reinforcement cage can be taken out. It should be noted here that when the frame body is an inseparable structure, it is necessary to first take out the steel reinforcement cage and multiple load - bearing members 2 together, then remove the load - bearing members 2 to obtain the steel reinforcement cage, and then reinstall the load - bearing members 2.

[0033] Preferably, referring to Figure 1 , there is a hollow between two connecting plates 15 belonging to the same half - frame 14 and with overlapping projections to form an anti - interference groove. With this setting, it is possible to prevent large - area contact between the two half - frames 14, so as to reduce the area that needs fine machining, thereby ensuring that the two connecting plates 15 are closely attached.

[0034] Preferably, referring to Figure 3 , a top cover 213 is fixed to the top of the socket shell 21. The top cover 213 is located directly above the guide rod 11 and is supported by the guide rod 11. With this setting, the guide rod 11 can support the socket shell 21 more stably and reliably.

[0035] Preferably, the load - bearing member 2 is made of acrylic material. With this setting, it is possible to prevent the epoxy steel bars from being scratched. It can be understood that if the strength of the load - bearing member 2 is to be improved, it can also be made of steel material or other metal materials, but it is preferably made of a material with a wear resistance lower than that of the steel bars. Preferably, the rack 1 is made of steel material.

[0036] Preferably, referring to Figure 2 , the groove 221 has a semi - circular structure to better match the steel bars.

[0037] The above - mentioned embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non - substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
