[0023] The utility model is described and illustrated in detail below in conjunction with the accompanying drawings.
[0024] Example 1
[0025] like Figures 1 - 3 As shown, the inserted reinforcement positioning device comprises a reinforcement frame 1, which is a rectangular structure formed by welding four reinforcement bars. A longitudinal reinforcement positioning device 2, a tie reinforcement positioning device 3 and a stabilizing bracket 4 are sequentially arranged on the reinforcement frame 1 from top to bottom. The longitudinal reinforcement positioning device 2 and the tie reinforcement positioning device 3 are both slidably connected to the reinforcement frame 1, and the stabilizing bracket 4 is welded to the bottom of the reinforcement frame 1. The tie reinforcement positioning device 3 comprises a positioning plate 5 slidably arranged on the inner side of the reinforcement frame 1, four fixing screws 6 symmetrically welded on both sides of the positioning plate 5, and two positioning tubes 7 welded on the positioning plate 5 in parallel and at intervals. The positioning tube 7 and the reinforcement frame 1 are vertically arranged, and the two fixing screws 6 on the same side are respectively located on both sides of the reinforcement frame 1, and a fixing plate 8 is sleeved on one end of the two fixing screws 6 on the same side away from the positioning plate 5. The fixing screws 6 pass through the fixing plate 8 and are threadedly provided with fixing nuts.
[0026] The steel frame 1, the longitudinal reinforcement positioning device 2, the tie reinforcement positioning device 3 and the stabilizing bracket 4 are all made of abandoned steel bars, steel plates and steel pipes on site, which saves costs; a scale is set on the steel frame 1; the longitudinal reinforcement positioning device 2 is welded according to the size of the longitudinal reinforcement of the structural column, and the positions of all the longitudinal reinforcements can be determined on site by only determining the position of the structural column; the tie reinforcement positioning device 3 is freely adjustable and can flexibly cope with different tie reinforcement spacings; when it is necessary to adjust the tie reinforcement positioning device 3, the fixing nut is unscrewed outward to make the fixing plate 8 disengage from the interference with the steel frame 1, and then the tie reinforcement positioning device 3 is moved up and down, and after moving to the appropriate position, the fixing nut is re-tightened to make the fixing plate 8 interfere with the steel frame 1.
[0027] The stabilizing bracket 4 is in an isosceles triangle structure as a whole. Two stabilizing brackets 4 are provided, and the two stabilizing brackets 4 are parallelly and symmetrically arranged on both sides of the reinforcement frame 1 .
[0028] The first positioning plate 5 is integrally in a cuboid structure. The width of the first positioning plate 5 is adapted to the spacing between the two side steel bars of the steel bar frame 1. The fixing plate 8 abuts against the steel bar frame 1 by tightening the fixing nut.
[0029] Through the above settings, after the formwork of the concrete wall and concrete column is erected, place this device in front of the wall and column where the steel bars need to be inserted. According to the height of the tie bars, adjust the position of the tie bar positioning device 3 up and down at any time through the scales on the steel bar frame 1. Drill holes in the formwork through the first positioning tube 7 with a drill bit, then pass the tie bars through the first positioning tube 7 and the formwork holes, and fix them. At this time, the position and lap length of the tie bars meet the specification requirements. Finally, move the first positioning plate 5 with the first positioning tube 7 to the position of the next tie bar to complete the embedding work of the tie bars for this wall and column. After completion, move the device to the front of the next wall or column where steel bars need to be inserted or put it back into the warehouse. This device makes the operation of embedding tie bars simple, and the tie bar positioning device 3 can be reused, improving the construction efficiency.
[0030] The longitudinal bar positioning device 2 includes a second positioning plate 9 slidably arranged on the outer surface of the steel bar frame 1. One side of the second positioning plate 9 is fixedly provided with a limiting plate 10. A plurality of second positioning tubes 11 are welded at intervals on the lower end surface of the limiting plate 10. Hinges 12 are welded on both sides of the upper end surface of the limiting plate 10, and an L-shaped plate 13 is welded on the top of the hinge 12.
[0031] Two through holes one are formed in the second positioning plate 9 to penetrate through the steel bar frame 1, and the steel bars on both sides of the steel bar frame 1 respectively penetrate through the two through holes one.
[0032] A first bolt is threadedly arranged through one end of the second positioning plate 9 away from the limiting plate 10, and two second bolts are threadedly arranged through both sides of the second positioning plate 9 close to the limiting plate 10. The first bolt and the two second bolts can both abut against the steel bar frame 1.
[0033] The two hinges 12 and the two L-shaped plates 13 are symmetrically arranged.
[0034] There are four second positioning tubes 11, and the four second positioning tubes 11 are respectively arranged at the four corners of the lower end surface of the limiting plate 10.
[0035] Four through holes two are formed in the limiting plate 10 to penetrate through the four second positioning tubes 11.
[0036] The inner diameter of the second positioning tube 11 is adapted to the diameter of the through hole two.
[0037] Through the above arrangement, after determining the bottom height of the frame beam, screw out bolts 1 and 2 to make the longitudinal reinforcement positioning device 2 out of conflict with the steel frame 1, then move the positioning plate 2 9 to drive the longitudinal reinforcement positioning device 2 to move, and after moving to a suitable height, re-tighten bolts 1 and 2 to make the longitudinal reinforcement positioning device 2 conflict with the steel frame 1, fix the longitudinal reinforcement positioning device 2, and then measure and determine any two adjacent sides of the structural column at the bottom position of the frame beam, and the construction personnel overlap any two adjacent sides of the limit plate 10 with any two sides of the structural column determined at the bottom of the beam, and fold the hinge 12 The L-shaped plate 13 is buckled on the square wood at the bottom of the beam side, and then a drill is used to drill a hole at the bottom of the beam through the positioning tube 11, and then a steel bar that meets the length requirement is passed through the positioning tube 11, and the steel bar is fixed. At this time, the longitudinal reinforcement position and verticality of the structural column meet the requirements. After completion, the L-shaped plate 13 is detached from the square wood at the bottom of the beam side through the hinge 12, the longitudinal reinforcement positioning device 2 is removed, and then the device is moved to the bottom of the next frame beam where reinforcement needs to be inserted or put back into the warehouse; the device makes the longitudinal reinforcement pre-embedding work simple to operate, and the longitudinal reinforcement positioning device 2 can be reused, thereby improving construction efficiency.
[0038] Working principle and process:
[0039] When pre-embedding the tie bar, screw out the fixing nut to make the fixing plate 8 disengage from the conflict with the steel frame 1, then move the positioning plate 5 to drive the tie bar positioning device 3 to move, and after moving to a suitable position, tighten the fixing nut again to make the fixing plate 8 conflict with the steel frame 1, and fix the tie bar positioning device 3; after the concrete wall and concrete column formwork are completed, place the device in front of the wall or column where the reinforcement needs to be inserted, and adjust the position of the tie bar positioning device 3 up and down at any time according to the height of the tie bar through the scale on the steel frame 1, and fix it. The drill bit drills a hole in the template through the positioning tube 7, and then the tie bar passes through the positioning tube 7 and the template hole and fixes it. At this time, the position and lap length of the tie bar meet the requirements of the specification. Finally, the positioning plate 5 with the positioning tube 7 is moved to the position of the next tie bar, so as to complete the pre-embedding of the tie bars of this wall or column; after completion, the device is moved to the next wall or column where the bars need to be inserted or put back into the warehouse; this device makes the pre-embedding of the tie bars simple to operate, and the tie bar positioning device 3 can be reused, thereby improving the construction efficiency.
[0040] When carrying out the embedded work of longitudinal reinforcement, first weld the longitudinal reinforcement positioning device 2 according to the size of the longitudinal reinforcement of the structural column. Then determine the height of the bottom of the frame beam, and screw out bolt 1 and bolt 2 outward to make the longitudinal reinforcement positioning device 2 disengage from the contact with the steel bar rack 1. Then move the second positioning plate 9 to drive the longitudinal reinforcement positioning device 2 to move. After moving to the appropriate height, tighten bolt 1 and bolt 2 again to make the longitudinal reinforcement positioning device 2 contact with the steel bar rack 1 and fix the longitudinal reinforcement positioning device 2. Then measure and determine any two adjacent sides of the structural column at the bottom of the frame beam. The construction workers make any two adjacent sides of the limiting plate 10 coincide with any two sides of the structural column determined at the bottom of the beam. Through the folding hinge 12, the L-shaped plate 13 is buckled on the square wood at the bottom of the beam side. Then drill a hole at the bottom of the beam with a drill bit through the second positioning pipe 11, and then pass the steel bar that meets the length requirement through the second positioning pipe 11 and fix the steel bar. At this time, the position and verticality of the longitudinal reinforcement of the structural column meet the requirements. After completion, make the L-shaped plate 13 disengage from the square wood at the bottom of the beam side through the hinge 12, remove the longitudinal reinforcement positioning device 2, and then move this device to the bottom of the next frame beam that needs steel bar insertion or put it back into the warehouse. This device makes the operation of embedded longitudinal reinforcement simple, and the longitudinal reinforcement positioning device 2 can be reused, improving the construction efficiency.
