Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar binding, and more specifically relates to a steel bar binding jig. Background Art

[0002] A steel jig, also known as a steel skeleton or steel mesh, is an auxiliary tool used in the construction industry to fix and support steel bars. In reinforced concrete structures, a steel jig ensures that the position, spacing and shape of the steel bars are accurate, thereby improving construction efficiency and ensuring project quality.

[0003] Prior art steel bar jigs, such as the Chinese utility model with announcement number CN 218803077U, disclose a steel bar binding jig, which quickly positions the main steel bars through the limiting grooves on the connecting seat, places them in sequence, and places the transverse steel bars layer by layer on the sliding rod. The transverse steel bars and the main steel bars are tied and fixed with wire at the intersection position of the transverse steel bars and the main steel bars, and a steel cage skeleton is formed after the tying is completed.

[0004] Although the existing steel bar binding jig can meet the needs of steel bar cage binding operations, a large number of transverse supports need to be set up during the steel bar cage binding process to support the transverse steel bars to keep the transverse steel bars level and avoid bending of the bound steel bar cage. After the steel cage is bound, a large number of supports supporting the transverse steel bars need to be pulled out, and then the entire jig is disassembled. The workload of pulling out the supports is large, and the disassembly efficiency is low. Utility Model Content

[0007] Two flat plates and two crossbeams form a pre-support frame of a rectangular structure. The side walls of the two crossbeams that are extended outward and away from each other are used to support the side walls opposite to the steel bar hoops. The opposite side walls of the two flat plates are provided with a plurality of steel bar support insertion holes evenly distributed along the four side edges of the flat plates.

[0021] It should be further explained that the drawings and implementation modes of the present invention mainly describe the concept of the present invention. On the basis of this concept, some specific forms and settings of connection relationships, positional relationships, power mechanisms, power supply systems, hydraulic systems and control systems may not be fully described.

[0022] The steel bar binding jig provided by the utility model is now described.

[0023] like Figure 1 and Figure 2 As shown, the first embodiment of the utility model provides a steel bar binding jig, including.

[0024] Please refer to Figure 1 and Figure 2 The present embodiment provides a steel bar binding jig, comprising two parallel and opposite flat plates 1 and two cross beams 2 which are respectively detachably assembled on both sides of the two vertical plates. The side walls of the flat plates 1 are provided with placement notches 12. One side of the end of the cross beam 2 is detachably connected to the corresponding placement notch 12. The two flat plates 1 and the two cross beams 2 form a pre-support frame of a rectangular structure. The assembly process is as follows: the two flat plates 1 are assembled as shown in FIG. Figure 1 The two free ends of the two side beams 2 are aligned with the two placement notches 12 on the same side, and the two free ends of the two side beams 2 are inserted into the placement notches 12 horizontally, so as to assemble the pre-support frame. It should be noted that the length and width of the plate 1 and the length of the beam 2 are all designed according to the size of the steel cage.

[0025] A placement notch 12 extends out from the other side of the end of the beam 2 to form an extended support portion, and the side walls of the extended support portions of the two beams 2 that are away from each other are used to support the side walls of the steel bars on both sides opposite to each other. That is to say, after the two free ends of the two beams 2 are inserted into the corresponding placement notches 12, the gap between the side walls of the two beams 2 that are away from each other is the horizontal width of the inside of the steel cage.

[0026] A plurality of steel bar support insertion holes 11 evenly distributed along the four side edges of the two flat plates 1 are provided on the opposite side walls of the two flat plates 1. The two steel bar support insertion holes 11 coaxially distributed on the two flat plates 1 are used for inserting the two free ends of the steel bars. The two steel bar support insertion holes 11 coaxially distributed on the two flat plates 1 form a group, which is used for inserting the two free ends of a single steel bar. The gap between the two flat plates 1 cannot exceed the length of the steel bar.

[0027] The process of binding the steel cage is as follows: Figure 1 As shown, all the steel bars required for binding the steel cage are respectively plugged into the multiple groups of steel support plug-in holes 11 to form a rectangular structure frame. No other support parts are required to support the steel bars, and the horizontal support and position fixation of the steel bars can be achieved. After the position of the steel bars is set, the required number of steel hoops are sequentially put on the outside of the rectangular structure frame composed of multiple steel bars. It should be noted here that the two opposite side walls of the steel hoops are respectively against the side walls of the two beams 2 that are away from each other, that is, the extended support parts of the two beams 2 that extend out of the notch 12 are used to rest on the two opposite side walls of the steel hoops to prevent the steel hoops from shaking horizontally. Then, the gap between the two adjacent steel hoops is reserved according to the construction needs, and then the workers can use the wire to bind the steel bars and the steel hoops together to form a steel cage.

[0028] After the steel cage is bound, it needs to be hoisted to the construction site for pouring concrete. At this time, the two plates 1 are moved away from each other, the gaps 12 are placed and separated from the free ends of the two beams 2, the pre-support frame is quickly disassembled, and then the disassembled beams 2 are pulled out of the steel cage, so that the construction workers can use the hoist to hoist the bound steel cage.

[0029] like Figure 1 As shown, the lateral accommodation width of the placement notch 12 is actually smaller than the lateral width of the beam 2. After the end side of the beam 2 is inserted into the placement notch 12, an extended support portion is formed on the other side of the end of the beam 2. The entire pre-support frame only uses two extended support portions to limit the position of the steel hoop. When disassembling, no other components are in contact with the side wall of the steel hoop, reducing the difficulty of disassembly.

[0030] Furthermore, a threaded hole is provided in one of the flat plates 1, and a reinforcing rod 15 passing through the threaded hole is threadedly connected in the threaded hole, and a threaded sleeve 13 coaxially distributed with the threaded hole is fixed to the side wall of the other flat plate 1, and the reinforcing rod 15 is threadedly connected to the threaded sleeve 13. By threading the reinforcing rod 15 and the threaded sleeve 13, the stability of the two flat plates 1 in a vertical state can be enhanced. In addition, when splitting and separating the two flat plates 1, the reinforcing rod 15 can be rotated in the opposite direction, so that the two flat plates 1 have a force to separate from each other, reducing the resistance of the workers to separate the two flat plates 1. At the same time, a turntable is fixed to the other end of the reinforcing rod 15, and the turntable is used to assist the workers to rotate the reinforcing rod 15, which is more labor-saving.

[0031] In addition, a through hole connected to the threaded sleeve 13 and coaxially distributed is opened on the side wall of the other flat plate 1. When the gap between the two flat plates 1 needs to be tightened, the reinforcing rod 15 can be rotated to pass through the threaded sleeve 13 and then through the through hole, so that the gaps between the multiple groups of steel bar support plug-in holes 11 on the two flat plates 1 can meet the plug-in support requirements of steel bar cages of different lengths.

[0032] Further, such as Figure 3 As shown, an L-shaped stopper 14 is rotatably provided on the side wall in the vertical direction of the placement notch 12, a cavity is axially provided on the crossbeam 2, and docking notches 21 are provided on the side walls of the placement notch 12 at the two free ends of the crossbeam 2 relative to the placement notch 12. The L-shaped stopper 14 passes horizontally through the docking notch 21 and then rotates to be misaligned with the docking notch 21, and the side wall of the L-shaped stopper 14 rests on the inner wall of the cavity, which can prevent the crossbeam 2 from sliding out laterally along the placement notch 12, causing the pre-support frame to fall apart.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
