Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for positioning main reinforcement bars in the construction of steel reinforcement components. Background Technology

[0002] Reinforced steel component segmentation refers to dividing the overall bridge tower reinforcement components into multiple reinforcement component segments along the height direction. The construction method of any reinforcement component segment includes: sequentially processing reinforcement unit components, reinforcement mesh and reinforcement blocks in a ground factory; transporting the reinforcement blocks to the construction area and assembling them into reinforcement component segments; hoisting the reinforcement component segments as a whole onto the tower; and then connecting and installing the reinforcement component segments after adjusting their alignment.

[0003] The construction of reinforced concrete components transforms a large number of high-altitude operations, such as steel bar welding, steel bar tying, spacer block installation, and embedded part installation, which originally required on-site work, into ground operations. This reduces the number of personnel working at heights by more than 60%, lowers safety risks, and improves project quality. However, due to the long length of existing steel bars, multiple people are required to work together during the tying process, tying them simultaneously from both ends to ensure that the steel bars are in a horizontal state. Alternatively, the height of one end of the steel bar can be determined before tying it, and then the other end can be tied to ensure that it is in a horizontal state. This process can easily affect the horizontality of the steel bars, thereby reducing the construction quality of the reinforced concrete components. Therefore, this application provides a method for positioning the main reinforcement bars in the construction of reinforced concrete components to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method for positioning the main reinforcement bars in the construction of steel reinforcement components, so as to solve the problem that the steel bars cannot be fixed during the existing steel reinforcement binding process and multiple people are needed to ensure that the steel bars are in a horizontal state.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A method for positioning main reinforcement bars in the construction of steel reinforcement components includes: a connecting component; a transmission component sleeved outside the connecting component; a fixing component sliding inside the transmission component; a receiving component fixedly installed at the bottom of the fixing component; the connecting component and the receiving component being fixedly connected; and a docking component connecting the transmission component and the receiving component; the receiving component includes a protective box fixedly installed at the bottom of the fixing component; a transmission rod sleeved inside the protective box; a transmission gear fixedly installed in the middle of the transmission rod; and receiving frames installed at both ends of the transmission rod, the receiving frames being "J" shaped.

[0007] Optionally, the transmission assembly includes two collars sleeved on the outside of the connecting assembly, and a toothed plate installed at the bottom of one of the collars, the toothed plate meshing with a transmission gear;

[0008] Push blocks are respectively fixedly installed inside the upper end of the two collars;

[0009] The transmission plates installed at both ends of the bottom of the push block, the limiting blocks fixed to the inner walls of the two collars, and the docking plate installed on the outside of the collar.

[0010] Optionally, the fixing component includes clamping plates that slide outside the two limiting blocks respectively, holes formed outside the two clamping plates, and stabilizing blocks fitted inside the holes;

[0011] The two clamping plates are respectively provided with guide grooves on their outer sides for the sliding of the limiting blocks.

[0012] Optionally, the two push blocks are combined to form a hollow cylinder with the inner diameter gradually increasing from top to bottom, and the two clamping plates are combined to form a hollow cylinder with the outer diameter gradually increasing from top to bottom.

[0013] The push block is adapted to the clamping plate.

[0014] Optionally, the connecting assembly includes a connecting plate fixed to the side of the protective box, a support rod fixed to the top of the connecting plate, a fixing plate sleeved on the outside of the support rod, a guide rod fixed to the side of the fixing plate, and a support block fixed to the middle of the guide rod.

[0015] The two docking plates are respectively sleeved on both ends of the guide rod, the first spring is connected between the fixed plate and the docking plate, and the telescopic rod is hinged between the collar and the fixed plate.

[0016] Optionally, the collar can be rotated and slid outside the guide rod via the mating plate, causing the clamping plate to unfold. The clamping plate and collar can then be fitted onto the outside of the vertical reinforcing bar using bolts.

[0017] Optionally, pulling the collar up disengages it from the clamping plate, and the toothed plate drives the transmission gear, transmission rod and receiving frame to rotate, which in turn drives the clamping plate to move upward through the limiting block.

[0018] Optionally, the receiving frame is moved up to a suitable height, the hand-held clamping plate is pressed down on the collar, and the upper end of the clamping plate is pressed by the pushing block to fix it to the outside of the reinforcing bar;

[0019] When the lowering collar is pressed down, the toothed plate drives the transmission gear, transmission rod and the receiving frame to rotate in opposite directions.

[0020] Optionally, the docking assembly includes a sleeve fixed to the bottom of the protective box, a connecting rod sleeved inside the sleeve, a second spring connected between the connecting rod and the sleeve, a protrusion installed outside the connecting rod, a handle assembled outside the connecting rod, and a connecting frame disposed between the connecting rod and the toothed plate; the sleeve has an "L"-shaped groove on its outside for the protrusion to slide.

[0021] Optionally, the protrusion is in a relaxed state when it is located at the right end of the "L"-shaped groove; the toothed plate drives the connecting frame and connecting rod to move down, and the protrusion slides down in the "L"-shaped groove. When it moves to the bottom, the protrusion drives the connecting rod and the protrusion to rotate, and it is located at the right end of the "L"-shaped groove, so that the transmission component and the fixed component form a whole.

[0022] Compared with the prior art, the present invention has at least the following beneficial effects:

[0023] In the above scheme, a clamping plate is fitted over the vertical reinforcing bar, and the height of the clamping plate is determined. Two collars and two clamping plates are fitted over the reinforcing bar using a screw. By holding the clamping plate and pressing down on the collars, the toothed plate is driven. The limiting block slides in the guide groove outside the clamping plate. The toothed plate drives the transmission gear, transmission rod and receiving frame to rotate, so that the receiving frame is in a horizontal state. The reinforcing bar to be tied can then be placed on the receiving frame. At the same time, multiple sets of positioning devices are set to support the reinforcing bar and keep it in a horizontal state, which facilitates the tying of the reinforcing bar and improves the quality of the reinforcing bar components.

[0024] The downward movement of the collar causes the pushing block to press against the upper end of the clamping plate. Because the hole is inclined, the downward movement of the transmission plate pushes the outer end of the stabilizing block, and positions the stabilizing block between two adjacent transverse ribs of the reinforcing bar. This improves the stability between the clamping plate and the reinforcing bar, prevents the reinforcing bar from falling downward during the receiving process, and ensures the horizontality of the reinforcing bar. It can also accommodate reinforcing bars of different sizes.

[0025] By rotating the docking assembly, the transmission assembly and the fixed assembly are disconnected. Pulling the collar upward causes the push block to disengage from the clamping plate. The transmission plate moves upward and disengages from the stabilizing block. The limiting block slides upward into the guide groove, which can then pull the clamping plate upward to move along the surface of the vertical rebar. After moving to the appropriate position, the collar moves downward to press and fix the clamping plate, thus facilitating the upward movement of the positioning device and improving the efficiency of preparing rebar components.

[0044] like Figure 1 and Figure 9As shown, an embodiment of the present invention provides a method for positioning main reinforcement bars in the construction of steel reinforcement components, including: a connecting component 300, a transmission component 100 sleeved on the outside of the connecting component 300, a fixing component 200 sliding inside the transmission component 100; a receiving component 400 fixedly installed at the bottom of the fixing component 200, the connecting component 300 and the receiving component 400 being fixedly connected; a docking component 500 connecting the transmission component 100 and the receiving component 400; the receiving component 400 includes a protective box 401 fixedly installed at the bottom of the fixing component 200, a transmission rod 403 sleeved inside the protective box 401, a transmission gear 402 fixedly installed in the middle of the transmission rod 403, and receiving frames 404 installed at both ends of the transmission rod 403, the receiving frames 404 being in a "J" shape.

[0045] The transmission assembly 100 includes two collars 101 sleeved on the outside of the connecting assembly 300, a toothed plate 103 mounted on the bottom of one of the collars 101, the toothed plate 103 meshing with a transmission gear 402; push blocks 102 fixedly mounted on the upper ends of the inner parts of the two collars 101; transmission plates 105 mounted on the bottom ends of the push blocks 102; limiting blocks 104 fixedly mounted on the inner walls of the two collars 101; and a docking plate 106 mounted on the outside of the collars 101. The fixing assembly 200 includes clamping plates 201 sliding on the outside of the two limiting blocks 104, holes 202 formed on the outside of the two clamping plates 201, and stabilizing blocks 203 sleeved inside the holes 202; guide grooves for the sliding of the limiting blocks 104 are respectively formed on the outside of the two clamping plates 201.

[0046] The two push blocks 102 are combined to form a hollow cylinder, with the inner diameter gradually increasing from top to bottom. The two clamping plates 201 are combined to form a hollow cylinder, with the outer diameter gradually increasing from top to bottom. The push blocks 102 and the clamping plates 201 are compatible.

[0047] By fitting the clamping plate 201 onto the outside of the vertical reinforcing bar and determining the height of the clamping plate 201, two collars 101 and two clamping plates 201 are fitted onto the outside of the reinforcing bar using screws. Holding the clamping plate 201 and pressing down on the collars 101 drives the toothed plate 103. The limiting block 104 slides in the guide groove outside the clamping plate 201. The toothed plate 103 pushes the transmission gear 402, transmission rod 403 and receiving frame 404 to rotate, so that the receiving frame 404 is in a horizontal state. At the same time, as the collars 101 move down, they drive the pushing block 102 to squeeze the upper end of the clamping plate 201. Meanwhile, since the outer end of the stabilizing block 203 is arc-shaped and the hole 202 is inclined, the transmission plate 105 moves down to push the outer end of the stabilizing block 203 and makes the stabilizing block 203 located between two adjacent transverse ribs of the reinforcing bar, thereby improving the stability between the clamping plate 201 and the reinforcing bar.

[0048] After lowering the collar 101 and fixing the clamping plate 201 to the outside of the reinforcing bar, the transmission component 100 and the fixing component 200 are integrated through the docking component 500. The reinforcing bar to be tied can then be placed on the receiving frame 404 for support. At the same time, the receiving frame 404 is in a "J" shape, so that the reinforcing bar at the top of the receiving frame 404 is always in close contact with the outside of the collar 101, which facilitates the tying of the reinforcing bar.

[0049] like Figures 2-5 As shown, the connecting assembly 300 includes a connecting plate 306 fixed to the side of the protective box 401, a support rod 305 fixed to the top of the connecting plate 306, a fixing plate 301 sleeved on the outside of the support rod 305, a guide rod 304 fixed to the side of the fixing plate 301, and a support block 303 fixed to the middle of the guide rod 304.

[0050] Two docking plates 106 are respectively sleeved on both ends of the guide rod 304, a first spring 302 is connected between the fixed plate 301 and the docking plate 106, and a telescopic rod 307 is hinged between the collar 101 and the fixed plate 301.

[0051] The rotating collar 101 slides outside the guide rod 304 via the docking plate 106, causing the clamping plate 201 to unfold. The clamping plate 201 and the collar 101 are fitted onto the outside of the vertical reinforcing bar with the help of bolts.

[0052] When the clamping plate 201 and the collar 101 need to be fitted onto the outside of the reinforcing bar, the collar 101 drives the limiting block 104 to slide upward into the guide groove, so that the limiting block 104 is located at the top of the guide groove. Rotating the collar 101 with the telescopic rod 307 as the central axis, the two connecting plates 106 slide to both ends outside the guide rod 304 to compress the first spring 302, so that the two collars 101 are in the open state. And through the limiting block 104, the two clamping plates 201 are in the open state, so that the clamping plate 201 and the collar 101 can be fitted onto the outside of the vertical reinforcing bar. Then, the collar 101 and the clamping plate 201 are fixed with bolts to form a closed ring.

[0053] like Figures 4-6 and Figure 9 As shown, the upper pull collar 101 disengages from the clamping plate 201 and drives the transmission gear 402, transmission rod 403, and receiving frame 404 to rotate via the toothed plate 103. This allows the clamping plate 201 to move upward via the limiting block 104. When the receiving frame 404 moves to a suitable height, the clamping plate 201 is held down and the collar 101 is pressed down. The upper end of the clamping plate 201 is pressed down by the pushing block 102, fixing it to the outside of the reinforcing bar. When the collar 101 is pressed down, the toothed plate 103 drives the transmission gear 402, transmission rod 403, and receiving frame 404 to rotate in opposite directions.

[0054] After fixing the clamping plate 201 and the collar 101 to the outside of the vertical rebar, the rebar to be tied can be placed on the top of the receiving frame 404. The receiving frame 404 supports it and keeps it in a horizontal state, so that it can be tied. After one layer of rebar is tied, the docking assembly 500 is rotated to disconnect the transmission assembly 100 from the fixing assembly 200. The collar 101 is pulled upward to make the pushing block 102 disengage from the clamping plate 201. At the same time, the transmission plate 105 moves upward to disengage from the stabilizing block 203. The limiting block 104 slides upward in the guide groove, so that the clamping plate 201 can be pulled upward to move along the surface of the vertical rebar. After moving to the appropriate position, the collar 101 moves downward to press and fix the clamping plate 201. The rebar to be tied can be fixed by the receiving frame 404.

[0055] like Figures 7-9 As shown, the docking assembly 500 includes a sleeve 501 fixed to the bottom of the protective box 401, a connecting rod 502 sleeved inside the sleeve 501, a second spring 503 connecting the connecting rod 502 and the sleeve 501, a protrusion 506 installed on the outside of the connecting rod 502, a handle 504 assembled on the outside of the connecting rod 502, and a connecting bracket 505 disposed between the connecting rod 502 and the toothed plate 103; the sleeve 501 has an "L"-shaped groove on its outside for the protrusion 506 to slide. The protrusion 506 is in a relaxed state when it is located at the right end of the "L"-shaped groove;

[0056] The toothed plate 103 drives the connecting frame 505 and the connecting rod 502 to move down, and the protrusion 506 slides down into the "L"-shaped groove. When it moves to the bottom, the second spring 503 drives the connecting rod 502 and the protrusion 506 to rotate, and it is located at the right end of the "L"-shaped groove, so that the transmission component 100 and the fixed component 200 form a whole.

[0057] The clamping plate 201 is pressed and fixed by the lowering collar 101, which simultaneously drives the toothed plate 103 to move downward, pushing the transmission gear 402, transmission rod 403 and receiving frame 404 to rotate. The receiving frame 404 can then receive the reinforcing bars to be tied. During the downward movement of the toothed plate 103, the connecting frame 505 and connecting rod 502 move downward, while the protrusion 506 moves downward and slides into the "L"-shaped groove. After moving to the bottom of the "L"-shaped groove, it rotates into the "L"-shaped groove under the action of the second spring 503. At the right end of the L-shaped groove, the protective box 401 is connected to the bottom of the clamping plate 201 and the sleeve 501 is connected to the bottom of the protective box 401. The toothed plate 103 is connected to the bottom of the collar 101. Thus, it is fixed to the sleeve 501 through the connecting rod 502. The toothed plate 103 will not be able to move. At this time, the transmission component 100 and the fixing component 200 will form a whole, thereby improving the stability between the clamping plate 201 and the steel bar and effectively preventing the support frame 404 from loosening during the process of supporting the steel bar.

[0058] The technical solution provided by this invention involves fitting a clamping plate 201 around the outside of a vertical reinforcing bar and determining the height of the clamping plate 201. Two collars 101 and two clamping plates 201 are fitted around the reinforcing bar using a screw. Holding the clamping plate 201 and pressing down on the collars 101 drives the toothed plate 103. A limiting block 104 slides in the guide groove outside the clamping plate 201. The toothed plate 103 drives the transmission gear 402, transmission rod 403, and receiving frame 404 to rotate, making the receiving frame 404 horizontal. The reinforcing bar to be tied can then be placed on the receiving frame 404. Simultaneously, multiple positioning devices are provided to support the reinforcing bar, keeping it horizontal, facilitating tying, and improving the quality of the reinforcing bar components.

[0059] The downward movement of the collar 101 causes the pushing block 102 to press the upper end of the clamping plate 201. Since the hole 202 is inclined, the downward movement of the transmission plate 105 pushes the outer end of the stabilizing block 203, and positions the stabilizing block 203 between two adjacent transverse ribs of the reinforcing bar. This improves the stability between the clamping plate 201 and the reinforcing bar, prevents the receiving frame 404 from falling downwards during the receiving process of the reinforcing bar, and ensures the horizontality of the reinforcing bar. At the same time, it can adapt to reinforcing bars of different sizes.

[0060] By rotating the docking assembly 500, the transmission assembly 100 is disconnected from the fixing assembly 200. Pulling the collar 101 upward causes the pushing block 102 to disengage from the clamping plate 201. The transmission plate 105 moves upward to disengage from the stabilizing block 203. The limiting block 104 slides upward into the guide groove, which can then pull the clamping plate 201 upward to move along the surface of the vertical steel bar. After moving to the appropriate position, the collar 101 moves downward to press and fix the clamping plate 201, thus achieving the purpose of facilitating the upward movement of the positioning device and improving the efficiency of steel bar component preparation.

[0061] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0062] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
