DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings.

[0024] The embodiment of the present application discloses a steel bar positioning structure for building construction.

[0025] Reference Figure 1 , Figure 2 The steel bar positioning structure for construction includes a plurality of fixing seats 1, and the fixing seats 1 include a fixing ring 10 and a movable ring 11 for mutually splicing and fixing. The fixing ring 10 and the movable ring 11 that are spliced ​​and fixed to each other are surrounded together to form a positioning hole 12 for the steel bar to pass through. The inner side walls of the fixing ring 10 and the movable ring 11 are fixedly provided with a protective pad 5 located in the positioning hole 12, and the protective pad 5 is used to fit with the outer side wall of the steel bar penetrating the positioning hole 12. The protective pad 5 can further increase the friction between the inner side wall of the positioning hole 12 and the outer side wall of the steel bar, so that the steel bar can be more stably and securely limited in each fixing seat 1.

[0026] like Figure 2 , Figure 3As shown, a connecting member 2 is provided between adjacent fixing rings 10 at the same height, and the connecting member 2 includes two connecting rods 20 arranged coaxially and an internally hollow internally threaded sleeve 21. The two connecting rods 20 are symmetrically arranged on both sides of the internally threaded sleeve 21, and the inner side walls at both ends of the internally threaded sleeve 21 are symmetrically provided with internal threads in opposite directions. One end of the connecting rod 20 is inserted from the openings of the internally threaded sleeve 21 opposite to each other and is threadedly connected in the internally threaded sleeve 21, and the other end of the connecting rod 20 is connected and fixed to the outer side walls of the fixing rings 10 opposite to each other. By rotating the internally threaded sleeve 21, the internally threaded sleeve 21 will drive the fixing rings 10 on both sides to move in a direction close to or away from each other through the connecting rod 20. Thereby, the purpose of adjusting the spacing between the main steel bars inserted into the positioning hole 12 can be achieved.

[0027] like Figure 2 , Figure 3 As shown, two plug-in components 100 are integrally formed on the outer side wall of the fixed ring 10 facing the respective movable rings 11, and the plug-in components 100 are symmetrically arranged on both sides of the positioning hole 12. A plug-in slot 110 is formed on the side wall of the movable ring 11 facing the plug-in component 100, and the plug-in slot 110 is used for the respective opposite plug-in components 100 to be inserted into the movable ring 11 from bottom to top, and the shape of the plug-in component 100 is adapted to the shape of the plug-in slot 110. By plugging and matching the plug-in component 100 and the plug-in slot 110, the movable ring 11 can be initially limited to one side of the fixed ring 10.

[0028] like Figure 2 , Figure 3 As shown, two locking seats 3 are fixedly installed on the top of the fixing ring 10, and the positions of the locking seats 3 are opposite to the plug-in slots 110. Locking members 30 are slidably arranged in the locking seats 3, and the upper openings of the plug-in slots 110 are respectively located on the sliding paths of the corresponding locking members 30, and the locking members 30 are used to limit the plug-in members 100 from being separated from the upper openings of the plug-in slots 110 where they are located.

[0029] like Figure 2 , Figure 3 As shown, a return spring 31 is arranged in the locking seat 3. The return spring 31 expands and contracts along the sliding direction of the locking member 30 in the locking seat 3. One end of the return spring 31 contacts the inner side wall of the locking seat 3, and the other end of the return spring 31 contacts the outer side wall of the respective opposite locking member 30. The return spring 31 is used to push the respective locking member 30 to move in the direction close to the movable ring 11 until the locking member 30 blocks the upper opening of the respective corresponding plug-in slot 110, at which time the movable ring 11 can be locked to one side of the fixed ring 10.

[0030] like Figure 2 , Figure 3As shown, a limiting groove 32 is provided on the outer wall of the locking member 30 facing away from the fixed ring 10, and the limiting groove 32 is located outside the locking seat 3. When it is necessary to release the locking member 30 from the movable ring 11, the locking member 30 is pushed away from the movable ring 11 by contacting the inner wall of the limiting groove 32 until the locking member 30 is moved out from the upper opening of the respective corresponding plug-in slots 110. At this time, the movable ring 11 can be smoothly taken out from the upper opening of the plug-in slots 110.

[0031] like Figure 2 , Figure 3 As shown, two mounting posts 4 are fixedly arranged on the outer side wall of the fixing ring 10, and the mounting posts 4 are symmetrically arranged on the upper and lower outer side walls of the fixing ring 10 which are away from each other. A support rod 40 is inserted and fixed in the mounting posts 4, and the length of the support rod 40 extends along the length direction of the central axis of the positioning hole 12. The upper end of the support rod 40 is used to be inserted into the mounting post 4 of the fixing seat 1 located at the upper layer, and the upper fixing seat 1 is supported and fixed by the support rod 40, so that the stability of the fixing seats 1 at each layer can be further improved.

[0032] The implementation principle is: when making a steel cage, each main steel bar located at the corner of the steel cage is inserted into the corresponding positioning hole 12. At this time, under the limit of each connector 2, the position of each main steel bar can be positioned, so that each main steel bar is not easy to be offset during the subsequent binding process, thereby ensuring the structural strength and straightness of the finished steel cage. When the spacing of each main steel bar to be positioned changes, the fixing rings 10 on both sides are moved towards or away from each other by rotating the internal threaded sleeve 21 under the drive of the connecting rod 20, so as to achieve the purpose of adjusting the spacing between the main steel bars inserted in the positioning hole 12.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
