Description

Technical Field

[0001] The invention relates to the technical field of steel bar positioning, in particular to a retaining wall vertical steel bar positioning structure and a fixing method thereof. Background Art

[0002] In modern building construction, the main structure is particularly important, as it affects the overall safety and quality of the structure. During the main structure construction process, basement retaining wall construction is the most complex, involving not only leakage prevention but also the positioning of vertical rebar. During actual construction, managers often focus primarily on preventing leakage from the retaining wall and often overlook the positioning and securing of the vertical rebar, resulting in misalignment of the vertical rebar.

[0003] During retaining wall construction, the positioning and securing of vertical reinforcement is crucial. Existing techniques typically rely on worker experience or simple wire drawing. However, due to the length of the vertical reinforcement and the need for vibration during concrete pouring, this method is difficult to accurately position and secure. This can easily cause the vertical reinforcement to shift during concrete pouring, leading to subsequent chiseling and repair issues, impacting overall construction quality and progress.

[0004] Based on this, a retaining wall vertical reinforcement positioning structure and a fixing method thereof are proposed. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention proposes a retaining wall vertical steel bar positioning structure and a fixing method thereof.

[0007] An enlarged foot, the enlarged foot being arranged on one side of the concrete base plate, and having two suction cups on the upper surface of the enlarged foot;

[0008] A stainless steel clip, wherein the plurality of stainless steel clips are respectively arranged on the surfaces corresponding to the plurality of vertical steel bars, a bolt hole is opened on one side of the stainless steel clip, a tooth groove is opened on the inner wall of the stainless steel clip, a horizontal bubble is set on the surface of the stainless steel clip, and the opposite surfaces of the plurality of stainless steel clips are fixedly connected to a spring 1;

[0009] The two ends of the stainless steel vertical poles are respectively fixedly connected to the stainless steel clamp and the surface of the rotating seat, and the opposite surfaces of the two stainless steel clamps are fixedly connected with two tension springs.

[0010] Preferably, the surface of the rotating seat is fixedly connected to a fixed seat, the inner wall of the fixed seat is fixedly connected to a sealing cylinder, the inner wall of the sealing cylinder is slidably connected to a piston block, the upper surface of the piston block is fixedly connected to a pull rod, and the top end of the pull rod is rotatably connected to a handle.

[0011] Preferably, two connecting rods are fixedly connected to the surface of the fixing seat, one end of the two connecting rods is fixedly connected to a sleeve, and the top ends of the two sleeves are fixedly connected to the same fixing plate.

[0012] Preferably, the bottom end of the sealing cylinder is fixedly connected to the upper surface of the suction cup, the lower surface of the handle is fixedly connected to two guide rods, and the upper surface of the fixed plate is provided with two holes, and the inner walls of the two holes are respectively slidably connected to the surfaces of the corresponding two guide rods.

[0013] Preferably, the surface of the sealing cylinder is fixedly connected with two connecting tubes, one end of the two connecting tubes is fixedly connected with the surfaces of the corresponding two sleeves, the inner walls of the two sleeves are slidably connected with lifting rods, the top ends of the two lifting rods are fixedly connected with compression springs, and the top ends of the two compression springs are fixedly connected with the inner top walls of the sleeves.

[0014] Preferably, the bottom ends of the two lifting rods are fixedly connected to plugs, the bottom ends of the two plugs are rotatably connected to rotating rods, the bottom ends of the two rotating rods are rotatably connected to positioning blocks, and the opposite surfaces of the two positioning blocks are fixedly connected to the same spring 2.

[0015] Preferably, a slot is provided on the upper surface of the enlarging foot, and two positioning slots are provided on the inner wall of the slot. The inner wall of the slot is slidably and detachably connected to the surface of the plug, and the inner walls of the two positioning slots are respectively slidably connected to the surfaces of the corresponding two positioning blocks.

[0016] A method for fixing vertical steel bars of a retaining wall, the method comprising the following steps:

[0017] S1: Clamp the stainless steel clamp on the surface of the vertical steel bar, use the inner tooth groove to bite the steel bar to ensure stability, and adjust the level of the stainless steel clamp through the level bubble to ensure the vertical positioning of the steel bar;

[0018] S2: Place the enlarged foot on one side of the concrete base plate, so that the suction cup is attached to the construction surface. Initially fix the device, press the plug downward to insert it into the slot. At the same time, the positioning block automatically snaps into the positioning slot under the action of the second spring, completing the locking.

[0019] S3: Pull up the handle to move the piston block in the sealing cylinder, creating negative pressure and increasing the suction force of the suction cup. The connecting pipe transmits the negative pressure to the sleeve, allowing the lifting rod to adjust its height under the action of the compression spring, further stabilizing the device.

[0020] S4: When pouring concrete, spring 1 and tension spring absorb vibration to prevent the steel bar from shifting. The horizontal bubble monitors the position of the steel bar in real time to ensure construction accuracy.

[0021] Compared with the prior art, the present invention has the following significant advantages:

[0022] First, the present invention clamps the stainless steel clamp on the vertical steel bar, increases friction through the tooth groove to ensure the position of the steel bar is fixed, and uses the bubble level to adjust the level of the stainless steel clamp to ensure the vertical positioning of the steel bar; the enlarged foot is placed on the side of the concrete base plate, and the suction cup is adsorbed on the construction surface to provide preliminary fixation. The plug is inserted into the slot, and the positioning block is snapped into the positioning groove under the action of the second spring to achieve rapid locking of the device and achieve a fixing effect;

[0023] Secondly, the present invention drives the piston block to move in the sealing cylinder through the pull rod by pulling the handle, thereby generating negative pressure, enhancing the adsorption force of the suction cup, and thus improving the fixing effect of the suction cup. During the rising process of the piston block, the air pressure inside the sealing cylinder is transmitted to the sleeve through the connecting pipe, thereby squeezing the lifting rod inside the sleeve. The lifting rod descends, thereby driving the plug to descend and insert into the slot. The plug continues to descend, squeezing the two rotating rods, causing the two rotating rods to rotate, thereby pushing the two positioning blocks to slide back to each other, thereby enabling the two positioning blocks to slide into the interior of the positioning groove, further improving the fixing effect.

[0024] Third: After the positioning block is inserted into the positioning groove, the handle is rotated. At this time, the guide rod is completely raised above the fixed plate. After the handle is rotated, the guide rod will contact the upper surface of the fixed plate, thereby limiting the pull rod and maintaining the fixing effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] A method for fixing vertical steel bars 4 of a retaining wall, the method comprising the following steps:

[0046] S1: Clamp the stainless steel clip 5 on the surface of the vertical steel bar 4, use the inner tooth groove 11 to bite the steel bar to ensure stability, and adjust the level of the stainless steel clip 5 through the level bubble 10 to ensure the vertical positioning of the steel bar;

[0048] S3: Pull up the handle 15, driving the piston block 19 to move in the sealing cylinder 18, creating negative pressure, which enhances the suction force of the suction cup 12. The connecting pipe 20 transmits the negative pressure to the sleeve 21, causing the lifting rod 23 to adjust its height under the action of the compression spring 22, further stabilizing the device;

[0049] S4: When pouring concrete, spring 1 8 and tension spring 7 absorb vibration to prevent the steel bar from shifting. The position of the steel bar is monitored in real time through the horizontal bubble 10 to ensure construction accuracy.

[0050] The specific working method is as follows: first, the stainless steel clamp 5 is clamped on the vertical steel bar 4, and the friction force is increased by the tooth groove 11 to ensure that the position of the steel bar is fixed.

After the handle 15 is rotated, the guide rod 16 will contact the upper surface of the fixed plate 14, thereby limiting the pull rod 17 and maintaining the fixing effect.
