Description

Technical Field

[0001] The utility model belongs to the technical field of construction tools, and in particular relates to a portable structural column embedded steel bar positioning device. Background Art

[0002] In construction, the precise positioning of pre-embedded rebar in structural columns is crucial to structural stability. Traditional rebar planting technology relies on manual drilling. During construction, even the slightest carelessness can damage the rebar and concrete at the top of the column, compromising the integrity of the main structure. Manual drilling also makes it difficult to precisely control the depth. Insufficient hole depth or poor curing of the rebar-setting adhesive can significantly reduce the anchoring strength of the rebar, impacting the bearing capacity of the column. Furthermore, due to the lack of precise positioning methods, traditional rebar-setting technology has a high drilling deviation rate, requiring frequent rework. The large number of unnecessary drill holes wastes materials such as rebar-setting adhesive and rebar, increasing construction costs.

[0003] The existing pre-embedded steel bar positioning device for structural columns has a complex structure and requires additional welding or assembly work during on-site construction. The device is also large and heavy, with poor portability. It is not suitable for single-person operation or rapid transfer, and cannot adapt to the efficient and flexible operation requirements of construction.

[0004] Chinese patent CN220814957U discloses a pre-embedded positioning device for structural column reinforcement, comprising a paint box, an outer sleeve, and a pressure rod. The paint box is filled with a sponge that absorbs pigment. The bottom of the paint box is provided with multiple structural column marking holes. The outer sleeve is fixed to the paint box and communicates with the paint box. The pressure rod is slidably mounted within the outer sleeve and can extend into the paint box to squeeze the sponge. When in use, the pressure rod is located within the outer sleeve, which provides a confined space for the pressure rod. The outer sleeve is welded to the paint box to make the paint box more stable during use. When marking, pigment is injected into the sponge in the paint box, and the pressure rod squeezes the sponge to cause the pigment in the paint box to seep out. At this time, the marking and positioning of the required pre-embedded reinforcement are performed through the bottom structural column marking hole. This patent is applicable to a variety of scenarios, improving work efficiency while reducing safety hazards. This patent uses pigment marking to locate the horizontal position of the embedded reinforcement, but it cannot control the extended length and anchor end length of the embedded reinforcement. Moreover, during construction, it is susceptible to interference such as vibration and collision, causing the marking position to shift, affecting positioning accuracy. Utility Model Content

[0033] The horizontal position of the embedded reinforcement 3 is controlled by the positioning plate 1 and the reserved hole 2, and the vertical length of the embedded reinforcement 3 is limited by the steel support member 10, which solves the problem of high drilling deviation rate in traditional reinforcement technology and improves the stress performance and structural stability of the structural column; through the cooperation of the hanging member 4 and the fixed claw 5, no on-site welding is required, and one person can quickly install and operate it, which meets the needs of efficient and flexible construction and shortens the construction time; the positioning plate 1 and the hanging member 4 fit tightly with the structural column support formwork 12, can resist interference such as vibration and collision during construction, have strong anti-disturbance performance, and ensure stable positioning accuracy.

[0034] Two vertical fixing plates 13 are provided at the bottom of the suspension member 4 to cooperate with the fastening operating rod 6.

[0035] A rotating shaft 14 is fixedly disposed between the two vertical fixing plates 13 .

[0036] The rotating shaft 14 passes through the fastening operating rod 6 , and the fastening operating rod 6 is rotatably connected to the rotating shaft 14 .

[0037] The vertical fixing plate 13 provides an installation base for the rotating shaft 14, ensuring that the tightening operating rod 6 can stably rotate around the rotating shaft 14 under the action of force. The operator can drive the fixing claw 5 to slide by pulling the tightening operating rod 6 to achieve locking and loosening of the fixing claw 5.

[0038] A template clamping claw 15 is fixedly provided on one end of the suspension member 4 away from the movable groove 7 .

[0039] The template claws 15 and the fixing claws 5 form a symmetrical hooking structure, which avoids the risk of tilting or falling off caused by single-point fixation and improves the installation stability of the device.

[0040] Both ends of the suspension member 4 are hooked on the structural column support formwork 12 through the formwork claws 15 and the fixing claws 5 respectively.

[0041] By cooperating with the template claws 15 and the fixing claws 5, the two ends of the suspension member 4 are hooked on the structural column support template 12, which significantly enhances the anti-disturbance performance; at the same time, the hooking installation does not require complicated tools, and a single person can quickly complete the fixation, thereby improving construction efficiency.

[0042] Self-locking blocks 16 are provided on both sides of the fixing claw 5 to cooperate with the suspension component 4.

[0043] The inner wall of the suspension member 4 is provided with a self-locking slot 17 in cooperation with the self-locking block 16 .

[0044] The self-locking block 16 cooperates with the self-locking slot 17 to automatically lock the fixed claw 5 after it is adjusted into place, preventing it from loosening or sliding under the action of external force during construction, thereby improving the reliability of the device positioning.

[0045] The tightening operating rod 6 is provided with a tightening handle.

[0046] The tightening handle provides the operator with a convenient force application point, making it easier to pull the tightening operating lever 6, and can significantly improve operating efficiency during batch installation or frequent adjustments.

[0047] The steel bar support member 10 is provided with a receiving groove to cooperate with the embedded reinforcement 3.

[0048] The receiving groove is precisely matched with the embedded reinforcement 3, which can form a vertical limit for the embedded reinforcement 3 and prevent the embedded reinforcement 3 from shifting left and right or shaking during the construction process.

[0049] Working principle and process:

[0050] 1. Construction preparation stage

[0051] According to the thickness and construction height of the structural column support template 12, the length of the telescopic riser 8 is pre-adjusted by the adjusting bolts 11 on the telescopic riser 8 so that the horizontal connector 9 and the steel support member 10 can adapt to the design height of the embedded reinforcement 3.

[0052] 2. Installation and Fixing of Positioning Plate 1 and Suspension Component 4

[0053] Place the positioning plate 1 at the preset position of the structural column support template 12 so that the positioning plate 1 fits the surface of the structural column support template 12 and the reserved hole 2 is aligned with the designed horizontal position of the embedded reinforcement 3.

[0054] First, the template claw 15 at one end of the suspension member 4 is hooked on the edge of the structural column support template 12 as a fixed fulcrum of the device.

[0055] The operator rotates and tightens the operating lever 6, driving the fixed claw 5 to slide in the suspension member 4, so that the fixed claw 5 contacts and presses the edge of the other side of the structural column support template 12. At the same time, the self-locking blocks 16 on both sides of the fixed claw 5 are inserted into the self-locking grooves 17 on the inner wall of the suspension member 4 to achieve mechanical locking. At this time, the suspension member 4 is tightly fixed to the structural column support template 12 through the two-way hooking of the template claw 15 and the fixed claw 5, completing the fixation of the device.

[0056] 3. Adjustment of telescopic riser 8

[0057] According to the designed anchoring end length of the embedded reinforcement 3, loosen the adjusting bolt 11 and adjust the length of the telescopic riser 8 so that the steel support members 10 on both sides of the horizontal connecting piece 9 are at a preset height. Then tighten the adjusting bolt 11 to lock the telescopic riser 8 to ensure that the receiving groove of the steel support member 10 can accurately receive the bottom of the embedded reinforcement 3.

[0058] 4. Positioning and fixing of embedded reinforcement 3

[0059] Pass the top of the embedded reinforcement 3 through the reserved hole 2 of the positioning plate 1, and place the bottom of the embedded reinforcement 3 into the receiving groove of the steel support member 10. After confirming that the embedded reinforcement 3 has no horizontal offset in the reserved hole 2 and no vertical shaking in the receiving groove, check again whether the adjusting bolt 11 of the telescopic riser 8 is locked.

[0060] 5. Device dismantling

[0061] After the embedded reinforcement 3 is fixed and formed, the tightening operating rod 6 is rotated in the opposite direction to disengage the self-locking block 16 from the self-locking slot 17, the fixed claw 5 releases the structural column support template 12, and the template claw 15 at one end of the suspension member 4 is removed to complete the device dismantling.
