DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figures 1-3 shown, the present invention provides a steel bar skeleton positioning structure for precast component production, including a base 100. The base 100 includes two upper connecting plates 101, two lower connecting plates 102, a connecting column 103, and a threaded rod 105. The connecting column 103 is arranged between the upper connecting plate 101 and the lower connecting plate 102. Connecting convex blocks 104 are arranged on the left and right sides of the upper connecting plate 101 and the lower connecting plate 102, and the threaded rod 105 passes through the connecting convex blocks 104;

[0025] The positioning component 200 is arranged on the upper surface of the base 100. The positioning component 200 includes an adjusting rod 201, a spring 202, a positioning plate 203 and a limiting post 204. Adjusting grooves 206 adapted to the adjusting rod 201 are formed on the surfaces of the upper connecting plate 101 and the lower connecting plate 102. The spring 202 is arranged between the adjusting rod 201 and the positioning plate 203. The positioning plate 203 is arranged at the front end of the spring 202. The limiting post 204 is arranged outside the upper connecting plate 101.

[0026] Furthermore, in this embodiment, the upper connecting plate 101 and the lower connecting plate 102 are of arc-shaped design. One upper connecting plate 101 and one lower connecting plate 102 are connected together by a connecting column 103 to form a group. The connecting column 103 is respectively screwed to the upper connecting plate 101 and the lower connecting plate 102. A nut 106 is fixed on one side of the connecting convex block 104. The threaded rod 105 is in threaded cooperation with the nut 106. The two groups of connecting plates are connected by the cooperation of the nut 106 and the threaded rod 105 to realize the assembly of the base 100.

[0027] In this embodiment, a plurality of adjusting grooves 206 are formed on the surfaces of the upper connecting plate 101 and the lower connecting plate 102. The adjusting grooves 206 are arranged in a circumferential array. The adjusting column passes through the upper connecting plate 101 and the lower connecting plate 102 through the adjusting grooves 206. The extending height of the adjusting column can be adjusted through the adjusting grooves 206, so as to adjust the positioning position of the positioning plate 203. And the bottom of the adjusting column is screwed to the mold.

[0028] In this embodiment, a limiting hole 205 adapted to the limiting post 204 is formed on the outer side of the adjusting column. The limiting post 204 passes through the upper connecting plate 101 and is in threaded cooperation with the adjusting column through the limiting hole 205. The extending height of the adjusting column is fixed by the limiting post 204 passing through the upper connecting plate 101.

[0029] In this embodiment, there are four positioning plates 203, all of which are of arc-shaped design. At least two adjusting columns are arranged at the rear side of each positioning plate 203. The two ends of the arc-shaped positioning plate 203 are stabilized by at least two adjusting columns. An activity block 209 is arranged at the front end of the spring 202. A fixing column 208 is fixed at the front end of the activity block 209. A connecting head 207 is fixed at the front end of the fixing column 208.

[0030] In this embodiment, the connecting head 207 is in threaded cooperation with the positioning plate 203. The activity block 209 is of hollow design. The front end of the spring 202 is fixedly connected to the inner bottom of the activity block 209. The rear end of the spring 202 is fixedly connected to the adjusting column. The spring 202 is fixed on the activity block 209 and is connected to the positioning plate 203 through the connecting head 207 on the fixing column 208 at the front end of the activity block 209.

[0031] In this embodiment, an activity groove 2011 for the movement of the spring 202 is formed inside the adjusting column. A guiding strip 2010 is fixed on the inner wall of the activity groove 2011. Guiding grooves 2012 adapted to the guiding strip 2010 are arranged on both sides of the movable block 209. The steel bars are placed through the activity groove 2011. The positioning plate 203 is pushed and moved by the steel bars. The spring 202 is compressed in the activity groove 2011, and the cooperation between the guiding strip 2010 and the guiding grooves 2012 realizes the guiding of the movement of the movable block 209 and the spring 202.

[0032] In this embodiment, the positioning plate 203 is made of one of polyamide or polycarbonate. The material of the positioning plate 203 enables the positioning plate 203 to adapt to steel bars of different shapes.

[0033] Specifically, when positioning the steel bar skeleton during production, first, the upper and lower connecting plates 102 are assembled together through the connecting column 103, and then the two groups of upper and lower connecting plates 102 are assembled together through the cooperation of the threaded rod 105 and the nut 106. Then, the adjusting column with the positioning plate 203 passes through the upper and lower connecting plates 102 through the adjusting groove 206. The bottom of the adjusting column is fixed in the mold by screws, which facilitates the disassembly and assembly of the positioning structure. The positioning structure can be installed horizontally or vertically according to the design of the steel bar skeleton.

[0034] When the steel bars are placed, one end of the steel bar is aligned with the arc-shaped hole formed by the four positioning plates 203. After the steel bars are placed, the positioning plate 203 is pushed and expanded outward by the steel bars. The expansion of the positioning plate 203 squeezes the spring 202 connected to the movable block 209 on the fixed column 208. The spring 202 is squeezed into the activity groove 2011 of the adjusting column. The acting force of the spring 202 makes the positioning plate 203 closely adhere to the outer surface of the steel bar to adapt to steel bars of different sizes, realizing the positioning of the steel bars in the mold. By fixing the position of the steel bar skeleton in the mold, the sinking of the steel bar skeleton caused by vibration can be reduced, the need for manual adjustment and correction can be reduced, the production process can be accelerated, and the production efficiency can be improved.

[0035] Considering that the spring 202 is deformed when being squeezed and will not be compressed linearly, a guiding strip 2010 is arranged on the inner wall of the activity groove 2011, and the cooperation with the guiding grooves 2012 on the movable block 209 is used for movement guiding to realize the directional movement of the spring 202. The length of the movable block 209 is reasonably set according to the normal length of the spring 202. When the spring 202 is in the normal state (i.e., the original state), the rear end of the movable block 209 is connected to the guiding grooves 2012 and does not separate.

[0036] A limit post 204 is provided on the outer side of the upper connecting plate 101, which can adjust the position of the adjustable base 100 on the adjusting post, that is, the extending length of the adjusting post. The limit post 204 passes through the upper connecting plate 101 and fixes the adjusting post on the upper connecting plate 101 through the limit hole 205, so as to adjust the positioning point of the positioning component 200 for the steel bar according to different strengths and achieve precise positioning.

[0037] The base 100, upper connecting plate 101, lower connecting plate 102, connecting column 103, connecting convex block 104, threaded rod 105, nut 106, adjusting rod 201, spring 202, positioning plate 203, limit post 204, connecting head 207, fixed post 208, movable block 209, guide bar 2010 and other components of the present utility model are all common standard parts or parts known to those skilled in the art, and their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.
