Description

Technical Field

[0001] This utility model mainly relates to the field of building construction engineering, and in particular to an auxiliary device suitable for rebar installation in secondary structures at high altitudes. Background Technology

[0002] Secondary structures refer to non-load-bearing masonry components in frame, shear wall, and frame-shear wall structures, including structural columns and lintels, which need to be completed before decoration. These structures do not directly bear the main load of the building, but they have a significant impact on the building's integrity, stability, and aesthetics. Because these structures are non-load-bearing, their load-bearing capacity is lower than that of load-bearing structures, making them prone to concrete cracking and damage during use. To improve the performance and durability of secondary structures and enhance the tensile, shear, and bending resistance of the concrete structure, rebar is usually installed in the secondary structure to connect it to the primary structure as a whole, thereby improving the overall integrity and safety of the structure.

[0003] When performing secondary structural rebar installation at heights such as the bottom of beams, an operating platform of at least 2.5 meters must first be erected. Construction workers must stand on the operating platform to perform tasks such as drilling, clearing, and applying adhesive. The working area is narrow, and the work at height poses safety hazards. In addition, the operating platform is large and cannot be moved by a single person. Construction workers need to repeatedly climb up and down the operating platform, wasting labor resources and resulting in low work efficiency.

[0004] In addition, because the bottom of the secondary structure is at a high position, simple string lines cannot ensure that the rebar positions of the upper and lower rebar beams of the secondary structure are in the same vertical direction, which may cause the rebars to be misaligned. Rework is required to adjust the rebar positions to ensure the construction quality of the secondary structure, but this will inevitably affect the normal construction schedule.

[0005] Therefore, to accelerate construction progress and improve labor utilization while ensuring safety and quality, a better auxiliary device suitable for high-altitude secondary structure rebar installation is needed to solve the above problems. Utility Model Content

[0006] In view of the shortcomings of the existing technology, this utility model provides an auxiliary device suitable for rebar installation in high-altitude secondary structures.

Second positioning nuts are installed in the adjustable elongated holes on the two connecting arms respectively. By tightening the second positioning nuts to engage with the threaded holes, the two connecting arms are fixed parallel to the telescopic rod and the support rod.

[0015] Furthermore, each of the connecting arms has anti-slip textures at its end.

The dust cover 231 can effectively prevent flying debris and dust during drilling operations, thereby protecting operators from injury and reducing the impact of the working environment.

[0048] The method of using the auxiliary device of this utility model for rebar installation in high-altitude secondary structures includes the following steps:

[0049] Step 1: Install the top cap 1, fixing rod 2, and telescopic rod 3, and align the adjusting elongated holes 401 on the two connecting arms 4 with the screw holes 16 on the telescopic rod 3 and the support rod 5 respectively. Then, use the second positioning nut 17 to initially fix the two connecting arms 4, and connect the telescopic rod 3, connecting arms 4, and support rod 5 into a whole.

[0050] Step 2: Insert the sliders 9 of all the first slider assembly 6, the second slider assembly 7 and the third slider assembly 8 into the slide rail 201, and install plastic threaded sealing plugs 202 at both ends of the slide rail 201;

[0051] Step 3: Install the infrared emitting device 15 on the third slider assembly 8. Adjust the position of the slider 9 in the two second slider assemblies 7 above the infrared emitting device 15 according to the size of the selected electric drill (not shown in the electric drill diagram). After determining the position, tighten the first positioning nut 10 and rotate the connecting screw 11 in the two second slider assemblies 7 so that the openings of the two fixing rings 13 are in the vertical direction, and ensure that the position of the electric drill bit is outside the mounting rod 12 so that the mounting rod 12 does not affect the operation of the drill bit.

[0052] Step 4: Adjust the diameter of the fixing rings 13 in the two second slider assemblies 7 to ensure that the selected electric drill can be inserted into the fixing rings 13. Place the electric drill vertically into the two fixing rings 13, and then tighten the fastening rings 14 of the two second slider assemblies 7 to fix the electric drill firmly.

[0053] Step 5: Rotate the connecting screw 11 of the third slider assembly 8 so that the infrared emitting device 15 faces the direction of the electric drill, and at the same time make the infrared rays emitted by the infrared emitting device 15 point upwards at the drill bit of the electric drill. Visually make sure that the two are on the same vertical line. After the adjustment is completed, rotate the infrared emitting device 15 180° towards the rebar planting position at the bottom of the secondary structure column.

[0054] Step 6: Secure the dust cover assembly 23 to the mounting rods 12 on the two first slider assemblies 6 and place it on the operator's side;

[0055] Step 7: Adjust the exposed length of the two connecting arms 4 within the adjusting elongated hole 401 to ensure convenient construction; after adjustment, the two connecting arms 4, the telescopic rod 3, and the support rod 5 form a parallelogram, and tighten the second positioning nut 17 to ensure that the connecting arms 4 do not move within the range of the adjusting elongated hole 401.

[0056] Step 8: Slide the universal wheel 18 to the required rebar area. The infrared emitting device 15 emits infrared rays downwards and aligns them with the rebar drilling hole at the bottom of the secondary structure column, so that the pre-drilled hole position of the upper part of the secondary structure column aligned with the rebar drilling hole position at the bottom of the column, and the deviation between the two is within the allowable range; rotate the handle 304 to adjust the threaded rod 302 to the appropriate length.

[0057] Step 9: Press the brake 19 to lock the caster wheel 18, and rotate the two support legs 20 downwards to a suitable angle. Tighten the third positioning nut 22 to ensure that the support rod 5 is stable as a whole.

[0058] Step 10: Grip the anti-slip texture 402 on the connecting arm 4 firmly, apply pressure slowly, turn on the electric drill, and drill by pressing down on the two connecting arms 4 (lever principle);

[0059] Step 11: After drilling is completed, loosen the third positioning nut 22, rotate it upward to lift the support leg 20, and at the same time rotate the handle 304 to retract the threaded rod 302 into the outer sleeve 301, thereby lowering the fixing rod 2, removing the electric drill, and the infrared emitting device 15 can also be removed.

[0060] Step 12: Install a glue gun and an exhaust hose (not shown in the figure) on the two second slider assemblies 7 on both sides of the slide rail 201 respectively. The installation method is the same as the fixing method of the electric drill. The glue gun and the exhaust hose are fixed by two fixing rings 13 and fastening rings 14 respectively. Install anchoring glue on the glue gun. Tie a rope to the bottom of the glue gun. Tie the other end of the rope to the anti-slip texture 402 of a connecting arm 4. Place the blower on the ground and connect the end of the exhaust hose to the blower.

[0061] Step 13: Place the brush (not shown in the brush diagram) in the brush groove 101 of the top cap 1. The brush must be firmly fixed. Adjust the threaded rod 302 to protrude by turning the handle 304, so that the fixing rod 2 rises. Release the brake 19, place the brush in the drill hole, and rotate the universal wheel 18 in place to clean the drill hole with the brush. Then remove the brush, place the exhaust hose at the drill hole, start the blower, and clean it further. Repeat 2-3 times to clean the inside of the drill hole.

[0062] Step 15: Place the glue gun at the cleaned drill hole and slowly inject the rebar adhesive into the drill hole by pressing the two connecting arms 4.

[0063] Step 16: Place the reinforcing bar (not shown in the reinforcing bar diagram) in the reinforcing bar groove 102. The reinforcing bar only needs to be ensured not to fall off during the movement of the device. Place the reinforcing bar in the drilled hole that has been filled with anchoring adhesive, and use the universal wheel 18 to rotate the device in place to make the reinforcing bar and anchoring adhesive in close contact.

[0064] Step 17: Repeat steps 8 to 16 until all secondary structure rebar installation at higher elevations is completed;

[0065] Step 18: Lower the device, clean the dust cover 231, disassemble, clean, and organize it to prepare for the next use.
