DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Refer to Figures 1-4, A precast box girder diaphragm steel bar positioning frame, including a support rod 1. A plurality of positioning rings 2 are movably sleeved on the outer side of the support rod 1 from top to bottom. Positioning rods 3 are fixedly connected to both symmetric sides of the positioning ring 2. A chute 4 is opened on the outer side of the support rod 1, and tooth grooves 8 are uniformly opened on the inner side wall of the chute 4. A locking screw rod 6 penetrates through the outer side of the positioning ring 2 by means of threads. One end of the locking screw rod 6 is rotatably connected to a movable block 5, and the movable block 5 is slidably connected in the chute 4. A plurality of engaging teeth 9 are uniformly installed on one side of the movable block 5, and the engaging teeth 9 can be engaged with the tooth grooves 8;

[0023] In the above - adopted technical solution, the main structure of the steel bar positioning frame is the support rod 1 and the positioning rods 3 distributed on both sides. The positioning rods 3 are used to carry the horizontal steel bars on the diaphragm and carry out steel bar binding. The positioning rings 2 can slide on the outer side of the support rod 1, so that the height of the positioning rods 3 and the distance between adjacent positioning rods 3 in the vertical direction can be adjusted. At the same time, the number of positioning rods 3 in the vertical direction can also be increased or decreased according to the actual situation. The method of fixing the position of the positioning ring 2 is as follows: when the positioning ring 2 slides up and down on the outer side of the support rod 1, the movable block 5 inside the positioning ring 2 will slide in the chute 4 on the support rod 1, and the arrangement of the movable block 5 and the chute 4 prevents the positioning ring 2 from rotating. After sliding to the corresponding position, by turning the locking screw rod 6, one end of the locking screw rod 6 drives the movable block 5 to translate inwardly along the chute 4 until the engaging teeth 9 on the movable block 5 are engaged with the tooth grooves 8 on the inner side of the chute 4, so as to achieve the purpose of restricting the up - and - down movement of the movable block 5 and the positioning ring 2. At this time, the fixing of the position of the positioning rod 3 is completed.

[0024] A T - shaped turning head 7 is arranged at one end of the locking screw rod 6, and a T - shaped turning groove is opened on the other side of the movable block 5, and the T - shaped turning head 7 is rotatably clamped inside the T - shaped turning groove;

[0025] In the above - adopted technical solution, the design of the T - shaped turning head 7 and the T - shaped turning groove is to facilitate the rotational connection between one end of the locking screw rod 6 and the movable block 5, so that the locking screw rod 6 can drive the movable block 5 to translate during the turning process.

[0026] A scale 10 is opened on the outer wall of the support rod 1 along the vertical direction, and a plurality of grooves 11 are opened on the upper surface of the positioning rod 3 along the horizontal direction;

[0027] In the above - adopted technical solution, the height of the positioning rod 3 and the distance between adjacent positioning rods 3 can be understood through the scale 10, improving the accuracy. A plurality of continuous grooves 11 are opened on the upper surface of the positioning rod 3, and the horizontal steel bars on the diaphragm are conveniently lapped through the grooves 11.

[0028] The bottom end of the support rod 1 is connected to a fixing column 12. Three reinforcing rods 13 distributed in an annular array are welded on the outer side of the fixing column 12, and a connecting rod 14 is welded between the bottom ends of the reinforcing rods 13;

[0029] In the technical solution adopted above, three reinforcing rods 13 and three connecting rods 14 form a tripod structure, thereby providing a stable ground support for the support rod 1. The tripod can be made of Φ22 steel bars.

[0030] A threaded column 16 is fixedly connected to the bottom end of the support rod 1. A threaded groove 15 is formed at the top end of the fixed column 12, and the threaded column 16 is connected to the inner side of the threaded groove 15.

[0031] In the technical solution adopted above, the support rod 1 and the fixed column 12 are connected by threading the threaded column 16, which facilitates their assembly. Thus, the support rod 1, the ground tripod, and the positioning rod 3 can be assembled and disassembled, facilitating the carrying of the device.

[0032] Working principle:

[0033] During use, the two layers of horizontal bars of the diaphragm are respectively placed on the corresponding positioning rods on both sides of the support rods of the positioning frame to achieve the positioning of the spacing of the horizontal bars and temporarily fix their vertical height. After the horizontal bars are positioned, the vertical bars of the diaphragm are successively tied. After the reinforcement bars of the diaphragm are tied, the positioning frame can be removed.

[0034] As described above, the above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
