Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to an auxiliary device for connecting steel cages. Background Art

[0002] The reinforcement cage of piles and piers is a structure used in foundations and main projects. Its main function is to provide tensile strength and restraint on concrete. In order to facilitate construction, the reinforcement cage is usually made in sections. Usually, the reinforcement cage made in sections includes at least two sections of reinforcement cage units, and each reinforcement cage unit is connected end to end. Each section of the reinforcement cage unit includes longitudinal reinforcement and transverse reinforcement. The reinforcement perpendicular to the ground in the reinforced concrete structure is the longitudinal reinforcement, and the reinforcement (hoop reinforcement) parallel to the ground is the transverse reinforcement. The transverse reinforcement and the longitudinal reinforcement are generally fixedly connected by welding. For the reinforcement cage made in sections, the reinforcement cage units are prefabricated first, and then each reinforcement cage unit is connected end to end at the groove section surface when the cage is lowered. Among them, when the two adjacent sections of the reinforcement cage units are connected, the corresponding longitudinal reinforcements in the two sections of the reinforcement cage units are fixedly connected, and the mechanical properties of the connection between the two sections of the reinforcement cage units are guaranteed as much as possible. Relative to the mechanical properties of the corresponding longitudinal reinforcements in the two sections of the reinforcement cage units do not change, so that the reinforcement cage as a whole has better mechanical properties. In order to prevent the mechanical properties of the steel cage from changing, when fixing two adjacent steel cage units, the longitudinal steel bars of the upper steel cage unit are aligned with the longitudinal steel bars of the lower steel cage unit as much as possible, and the gap between the end of the longitudinal steel bars of the upper steel cage unit and the end of the longitudinal steel bars of the lower steel cage unit is reduced as much as possible.

[0003] In the prior art, the diameter of the longitudinal steel bars of the pile pier reinforcement cage is relatively large, and a straight thread mechanical connection is generally used during connection. The sleeves on the multiple longitudinal steel bars of the reinforcement cage are tightened one by one with a wrench, which is inefficient. In addition, when connecting two sections of reinforcement cages, a crane is usually used to hang one reinforcement cage on the other reinforcement cage. The reinforcement cage is hung for a long time, increasing the safety risk. Utility Model Content

[0040] Example:

[0041] This embodiment provides an auxiliary device for connecting a steel cage, which is used to solve the technical problem of low steel cage connection efficiency in the prior art. The auxiliary device for connecting a steel cage includes two sections of steel cages. Specifically, the steel cage includes a plurality of longitudinal steel bars and transverse steel bars, and the plurality of longitudinal steel bars and transverse steel bars are connected together by welding. The two steel cages are respectively a first steel cage 7 and a second steel cage 8, and the second steel cage 8 is located directly above the first steel cage 7. The auxiliary device also includes a sleeve 1, a support ring 2, and an outer ring 3, wherein:

[0042] There are multiple sleeves 1, which are respectively screwed on the top ends of multiple longitudinal steel bars of the first steel cage 7. The inner wall of the sleeve 1 is provided with an internal thread, and the top ends of multiple longitudinal steel bars of the first steel cage 7 are provided with an external thread that matches the internal thread.

[0043] The support ring 2 is installed in the first steel cage 7 and abuts against each sleeve 1 , that is, the outer diameter of the support ring 2 abuts against the outer side wall of each sleeve 1 .

[0044] The outer ring 3 is sleeved outside each sleeve 1 and abuts against each sleeve 1. The outer ring 3 is used to drive each sleeve 1 to rotate. Through the setting of the outer ring 3, when the outer ring 3 is turned, the friction between the outer ring 3 and the sleeve 1 makes multiple sleeves 1 rotate in the same direction together.

[0045] By means of the above structure, when the auxiliary device for connecting steel cages provided by the utility model is used to connect two sections of steel cages, the second steel cage 8 is first hoisted above the first steel cage 7, and the bottom ends of the multiple longitudinal steel bars on the second steel cage 8 are made to correspond one by one with and be connected to the top ends of the multiple longitudinal steel bars on the first steel cage 7. Then, the sleeves 1 screwed on the top ends of the multiple longitudinal steel bars of the first steel cage 7 are rotated upward by two threads one by one, so that one end of the sleeve 1 is screwed on the bottom ends of the multiple longitudinal steel bars of the second steel cage 8. In this way, the first steel cage 7 and the second steel cage 8 are prevented from being misaligned, which causes the sleeve 1 to be unable to rotate from the top ends of the multiple longitudinal steel bars of the first steel cage 7 to the bottom ends of the multiple longitudinal steel bars of the second steel cage 8. Then, the outer ring 3 is moved to rotate the outer ring 3, so that the multiple sleeves 1 abutting against the outer ring 3 rotate at the same time. Each sleeve 1 simultaneously moves toward the longitudinal steel bars corresponding to the second steel cage 8 until the sleeve 1 is evenly connected to the longitudinal steel bars of the first steel cage 7 and the longitudinal steel bars of the second steel cage 8. In this way, through the setting of the outer ring 3, multiple sleeves 1 rotate together, which not only improves the connection efficiency, but also reduces the time for the second steel cage 8 to be lifted, thereby reducing the probability of accidents. Through the setting of the support ring 2, it is prevented that the multiple longitudinal steel bars of the first steel cage 7 are offset in a direction close to each other when the outer ring 3 rotates, thereby causing the sleeve 1 to separate from the outer ring 3, and then making the auxiliary device for connecting the steel cage provided by the utility model invalid. Therefore, through the cooperation between the outer ring 3 and the support ring 2, the auxiliary device for connecting the steel cage provided by the utility model improves the connection efficiency between the two sections of the steel cage, and saves time and effort.

[0046] An optional implementation of this embodiment is as follows: the support ring 2 includes an inner ring 21 and a reinforcing rib 22, wherein:

[0047] The inner ring 21 is installed in the first steel cage 7, and the outer wall of the inner ring 21 abuts against the outer wall of each sleeve 1, that is, the outer diameter of the inner ring 21 is equal to the inner diameter of the circular ring formed by multiple sleeves 1, so that the inner ring 21 abuts against the outer wall of each sleeve 1.

[0048] Both ends of the reinforcing rib 22 are installed on the inner wall of the inner ring 21, and the length of the reinforcing rib 22 is equal to the inner diameter of the inner ring 21. In this way, the arrangement of the reinforcing rib 22 can prevent the inner ring 21 from being deformed and causing the sleeve 1 to separate from the inner ring 21.

[0049] Optionally, there are multiple reinforcing ribs 22, all of which are installed in the inner ring 21, and the intersection of the multiple reinforcing ribs 22 is located at the center of the inner ring 21. In this way, the possibility of deformation of the inner ring 21 is further reduced by the arrangement of multiple reinforcing ribs 22.

[0050] An optional implementation of this embodiment is as follows: it also includes a locking assembly 4 installed on the outer ring 3, and the locking assembly 4 is used to open and lock the outer ring 3. In this way, the setting of the locking assembly 4 makes it easier to disassemble and assemble the outer ring 3.

[0051] Optionally, the locking assembly 4 includes two connecting plates 41, a screw rod 42 and a locking nut 43, wherein:

[0052] The outer ring 3 is provided with an opening, and the two connecting plates 41 are both installed at the opening, and the two connecting plates 41 are arranged opposite to each other. Optionally, the two connecting plates 41 can be fixedly installed on the outer ring 3, and can also be detachably installed on the outer ring 3.

[0053] Through holes are formed on the two connecting plates 41 , and the screw rods 42 are installed in the two through holes. The through holes on the two connecting plates 41 are coaxially arranged, so that it is easier to install the screw rods 42 in the two through holes.

[0054] There are two locking nuts 43 , which are respectively screwed on both ends of the screw rod 42 and located on the outsides of the two connecting plates 41 , that is, the two locking nuts 43 are respectively located on the opposite sides of the two connecting plates 41 .

[0055] Through the above structure, when the outer ring 3 needs to be installed outside multiple sleeves 1, the two connecting plates 41 are first pulled apart in the direction away from each other to increase the inner diameter of the outer ring 3, and then the outer ring 3 is sleeved on the multiple sleeves 1. In this way, the outer ring 3 with an enlarged inner diameter is easier to be sleeved outside the multiple sleeves 1. After the outer ring 3 is sleeved on the sleeve 1, the screw 42 is installed in the two through holes, and finally the two locking nuts 43 are respectively screwed on the two ends of the screw 42, so that the inner wall of the outer ring 3 is abutted against the outer wall of each sleeve 1. In this way, through the setting of the locking nut 43, it is easier to adjust the friction between the outer ring 3 and the sleeve 1.

[0056] Optionally, a rubber strip 6 is further included, which is installed on the side of the outer ring 3 close to the sleeve 1. In this way, the friction between the outer ring 3 and the sleeve 1 is increased by the setting of the rubber strip 6, making it easier for the outer ring 3 to drive the sleeve 1 to rotate.

[0057] Optionally, the outer side wall of the sleeve 1 is provided with anti-skid vertical lines, so that the friction between the outer ring 3 and the sleeve 1 is further increased by the provision of the anti-skid vertical lines, and the probability of relative rotation between the outer ring 3 and the sleeve 1 is further reduced.

[0058] An optional implementation of this embodiment is as follows: it also includes a handle assembly 5 installed on the outer ring 3, so that the setting of the handle assembly 5 makes it easier for the staff to rotate the outer ring 3.

[0059] Optionally, the handle assembly 5 includes a connecting rod 51 and a connecting ring 52, wherein:

[0060] One end of the connecting rod 51 is fixedly mounted on the outer side wall of the outer ring 3. Optionally, the connecting rod 51 can be connected to the outer ring 3 by welding, bonding or hot melting. Of course, it can also be integrally formed.

[0061] The connecting ring 52 is sleeved outside the connecting rod 51, and the other end of the connecting rod 51 is fixedly mounted on the inner wall of the connecting ring 52. In this way, through the setting of the connecting ring 52, the outer ring 3 can be driven to rotate without the staff standing at a predetermined position.

[0062] Optionally, there are multiple connecting rods 51 , and the multiple connecting rods 51 are evenly distributed between the outer ring 3 and the connecting ring 52 . In this way, the connection between the outer ring 3 and the connecting ring 52 is enhanced by the provision of multiple connecting rods 51 .

[0063] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
