[0002] Reinforcing steel bar refers to steel material for reinforced concrete and prestressed reinforced concrete, its cross section is circular, sometimes square with rounded corners, reinforcing steel bar is widely used in various building structures, especially large, heavy, light, thin-walled and high-rise building structures, and in building construction, reinforcing steel bar positioning structure is often used to position reinforcing steel bar to ensure construction quality in later period.

[0003] The inventor found in daily life that many traditional reinforcing steel bar positioning structures have low positioning accuracy. In some large building projects or building projects with high structural accuracy requirements (such as high-rise buildings, bridges, etc.), traditional positioning structures cannot meet the accurate requirements of design drawings on reinforcing steel bar positions. On the other hand, traditional reinforcing steel bar positioning structures lack flexibility. Different building construction scenes and design requirements require diversified reinforcing steel bar positioning methods, but existing positioning structures can only be applied to reinforcing steel bars of specific specifications and shapes, and cannot meet the positioning requirements of special-shaped reinforcing steel bars or reinforcing steel bars with special layouts. For example, in the construction of some buildings with unique shapes (such as the dome structure of a gymnasium), traditional positioning structures cannot be flexibly adjusted to adapt to complex reinforcing steel bar arrangements, increasing construction difficulty and cost.

[0004] Some existing reinforcing steel bar positioning structures are relatively complicated to operate. Construction personnel need to spend a lot of time and effort to install, debug and fix reinforcing steel bars, which not only reduces construction efficiency, but also may cause inaccurate positioning of reinforcing steel bars due to improper operation. Moreover, traditional positioning structures have problems in stability and are prone to displacement due to external forces during concrete pouring and other construction processes, affecting the final positioning effect of reinforcing steel bars UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] Please refer to Figures 1-5 The utility model provides a technical scheme: a reinforcing steel bar positioning structure for building construction, including base 1, the upper surface fixed connection of base 1 has moving assembly 2, the both ends of base 1 upper surface all are fixedly set with first electric push rod 3, and the telescopic end of first electric push rod 3 is fixedly connected with top plate 4, and the upper surface of top plate 4 is embedded with scale 5.

[0025] The specific settings and functions of the moving assembly 2, the positioning arm 27 and the clamping structure 28 will be described below.

[0026] In this embodiment: the moving assembly 2 includes a first fixed frame 21 and a second fixed frame 22, which are fixedly connected to the upper surface of the base 1. The first fixed frame 21 is provided with a first lead screw 23 inside, and the second fixed frame 22 is provided with a second lead screw 24 inside. The first fixed frame 21 is fixedly installed with a first motor 25 on one side surface, and the second fixed frame 22 is fixedly installed with a second motor 26 on one side surface. The output end of the first motor 25 is fixedly connected with the first lead screw 23, and the end of the first lead screw 23 away from the first motor 25 is rotatably connected with the inner wall of the first fixed frame 21. The output end of the second motor 26 is fixedly connected with the second lead screw 24, and the end of the second lead screw 24 away from the second motor 26 is rotatably connected with the inner wall of the second fixed frame 22. The outer surfaces of the first lead screw 23 and the second lead screw 24 are both screw-connected with the positioning arm 27, and the end of the positioning arm 27 away from the lead screw is fixedly connected with the clamping structure 28.

[0027] The effects achieved by the above components are that the first fixed frame 21 and the second fixed frame 22 provide a stable mounting basis for the first lead screw 23 and the second lead screw 24, ensuring that the lead screws will not deviate during rotation. When the first motor 25 is started, the torque output by the first motor 25 drives the first lead screw 23 to rotate in the first fixed frame 21. Since the positioning arm 27 is threadedly connected with the first lead screw 23, according to the screw transmission principle, the positioning arm 27 will move along the axial direction of the first lead screw 23. Similarly, when the second motor 26 drives the second lead screw 24 to rotate, the positioning arm 27 will also produce corresponding movement on the second lead screw 24. By controlling the forward and reverse rotation and the rotation angle of the first motor 25 and the second motor 26, the position of the positioning arm 27 on the horizontal plane can be accurately adjusted, thereby achieving precise positioning of the steel bar in the horizontal direction. Compared with the traditional manual adjustment method, this moving assembly 2 design based on lead screw transmission has higher positioning accuracy and is more convenient and efficient to operate, and can meet the precise requirements for the horizontal position of the steel bar in different construction scenes.

[0028] Specifically, the positioning arm 27 includes a first connecting block 271, the surface of the first connecting block 271 is fixedly connected with a lower electric push rod 272, the upper surface of the first connecting block 271 is fixedly connected with a second electric push rod 273, the telescopic end of the second electric push rod 273 is fixedly connected with a second connecting block 274, and the surface of the second connecting block 274 is fixedly connected with an upper electric push rod 275.

[0029] The effects achieved by the above components are that the cooperative work of the three electric push rods enables the positioning arm 27 to flexibly and accurately adjust the position of the clamping structure 28 in three-dimensional space, greatly improving the flexibility and accuracy of steel bar positioning, and being able to adapt to various complex shape and layout steel bar positioning requirements.

[0030] Specifically, the surface of the top plate 4 is provided with a reserved groove 41, the inside of the reserved groove 41 is fixedly connected with a connecting rod 42, and the connecting rod 42 is slidingly connected with the second connecting block 274.

[0031] The effects achieved by the above components are that this can effectively prevent the second connecting block 274 from deviating or shaking during movement, and ensure the linearity and stability of the movement of the positioning arm 27 in the horizontal direction.

[0032] Specifically, the clamping structure 28 includes a mounting plate 281, the surface of the mounting plate 281 is fixedly connected with a semicircular plate 282, the surface of the semicircular plate 282 is hingedly connected with a fixed plate 283, the fixed plate 283 and the semicircular plate 282 are clamped through a clamping block 284, and the inside of the semicircular plate 282 and the fixed plate 283 is fixedly connected with a buffer assembly 285.

[0033] The effects achieved by the above components are that the buffer assembly 285 plays an important role when the steel bar is impacted by external force during concrete pouring and other construction processes.

[0034] Specifically, the buffer assembly 285 includes a spring 2851 located on the inner wall of the semi-arc plate 282, and the end of the spring 2851 away from the semi-arc plate 282 is fixedly connected with a connecting plate 2852.

[0035] The above component achieves the effect that when the steel bar is subjected to external force, the connecting plate 2852 first contacts the external force and transmits it to the spring 2851. The spring 2851 has good elasticity and can absorb and buffer the external force through its elastic deformation such as compression or stretching.

[0036] Specifically, the lower end of the base 1 is fixedly connected with a non-slip pad 11 located at the four corners of the lower surface of the base 1.

[0037] The above component achieves the effect of ensuring the stability of the entire steel bar positioning structure and providing a reliable basis for accurate positioning of the steel bar.

[0038] Specifically, the telescopic ends of the lower electric push rod 272 and the upper electric push rod 275 are fixedly connected with clamping structures 28, and the clamping structures 28 are fixed on the telescopic ends of the lower electric push rod 272 and the upper electric push rod 275 through bolts.

[0039] The above component achieves the effect that the two clamping structures 28 cooperate with each other to form a stable fixing system, effectively preventing the steel bar from tilting or shaking during positioning.

[0040] Working principle: by controlling the operation of the first motor 25 and the second motor 26, the position of the positioning arm 27 in the moving assembly 2 in the horizontal direction is adjusted. The first motor 25 drives the first lead screw 23 to rotate, so that the positioning arm 27 moves on the first lead screw 23; the second motor 26 drives the second lead screw 24 to rotate, further accurately adjusting the horizontal position of the positioning arm 27. Then, according to the height of the steel bar, the first electric push rod 3 is started, and the second electric push rod 273 moves synchronously with the first electric push rod 3. In use, the top plate 4 is telescoped to the appropriate height position, and at the same time, the lower electric push rod 272 and the upper electric push rod 275 can adjust the position in the horizontal direction. When the clamping structure 28 moves to the predetermined position of the steel bar, the fixing plate 283 of the clamping structure 28 is opened, the steel bar is placed on the semi-arc plate 282, and then the fixing plate 283 and the semi-arc plate 282 are clamped through the clamping block 284, tightly clamping the steel bar. Since the telescopic ends of the lower electric push rod 272 and the upper electric push rod 275 are provided with the clamping structure 28, the steel bar can be fixed doubly, ensuring the stability of the steel bar during positioning.
