Description
Technical Field
[0001] This utility model relates to the field of prefabricated construction technology in building engineering, and in particular to an EMC rebar positioning auxiliary device. Background Technology
[0002] The precast wall panels are internally perforated with corrugated metal pipes to form a composite shear wall system with vertical holes. The vertical longitudinal reinforcements inside the wall panels are mechanically connected or lapped within the corrugated pipes, and concrete is poured afterward within the corrugated pipes. The EMC precast hollow composite shear wall structure only has vertical structural reinforcements and edge member stirrups and tie bars to form a reinforcement cage. A small number of large-diameter longitudinal reinforcements are arranged continuously within the edge members. The large-diameter continuous longitudinal reinforcements of the upper and lower edge members are mechanically connected. The precast wall body is provided with quincunx-shaped outward connecting reinforcements. The lower layer reinforcements extend from the top of the precast wall panel and lap into the corrugated pipes of the upper precast wall panel for connection.
[0003] In the current precast wall installation process, the lower layer of outward-extending connecting steel bars needs to be inserted into the corrugated pipe of the upper layer of precast wall panel. This process requires manual alignment of the steel bars with the corrugated pipe holes. Manual alignment not only requires extremely high precision, but in actual operation, it is difficult for operators to ensure that the alignment is accurate every time, which often leads to deviations. In addition, the manual alignment process is relatively cumbersome and time-consuming, which greatly increases the complexity and difficulty of construction, and thus has an adverse impact on the overall construction efficiency on site. Therefore, an EMC steel bar positioning auxiliary device is needed. Utility Model Content

[0011] Preferably, a groove is provided at the corresponding position of the vertical rod and the gear, and the gear is movably connected inside the groove of the vertical rod.
[0012] The beneficial effects of this utility model are as follows: Compared with the traditional precast wall hoisting process, which requires manual alignment of the reinforcing bars and corrugated pipe holes, which is prone to deviation and is relatively tedious and time-consuming, affecting on-site construction efficiency, this device pushes the buckle to slide on the outside of the horizontal sliding rod. The buckle spacing is adjusted according to the spacing of the reinforcing bars. After adjustment, the bolt is rotated to fix the buckle.

Finally, the reinforcing bar is placed into the buckle, ensuring that the reinforcing bar is vertical from top to bottom. This avoids the deviation of manual alignment and can quickly fit the corrugated pipe into the reinforcing bar, significantly improving construction efficiency. Attached Figure Description

Detailed Implementation
[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment: an EMC rebar positioning auxiliary device, including a base plate 1, a horizontal bar 501, and an adjustment assembly; a vertical bar 2 is provided at the upper end of the base plate 1, a vertical sliding bar 3 is provided on the outer side of the vertical bar 2, a connecting rod 4 is provided on one side of the vertical sliding bar 3, an adjustment assembly is provided on one side of the vertical sliding bar 3, a horizontal bar 501 is provided on one side of the connecting rod 4, an elastic fixing block 502 is provided on one side of the horizontal bar 501, a threaded sleeve 503 is provided on the outer side of the elastic fixing block 502 to retract the elastic fixing block 502, and a horizontal sliding bar is provided on the inner side of the elastic fixing block 502. 504, a buckle 505 is provided on the outer side of the horizontal slide bar 504, and a bolt 506 is provided on the inner side of the buckle 505 to fix the buckle 505. The inner side of the threaded sleeve 503 is tapered and engages with the elastic fixing block 502. Due to the tapered design of the inner side of the threaded sleeve 503, rotating the threaded sleeve 503 causes the elastic fixing block 502 to retract and fix the horizontal slide bar 504. A groove is opened at the corresponding position of the horizontal bar 501 and the horizontal slide bar 504. The horizontal slide bar 504 is slidably connected inside the groove of the horizontal bar 501. A groove is provided at the corresponding position of the horizontal sliding rod 504, so that the horizontal sliding rod 504 has a limiting effect when sliding inside the groove. There are two sets of horizontal rods 501, which are symmetrically arranged on both sides of the connecting rod 4. The two sets of horizontal rods 501 improve the practicality and ease of operation of the device. By rotating the bolt 506, the limiting of the buckle 505 is released, and then the buckle 505 is pushed to slide outside the horizontal sliding rod 504. The spacing of the buckles 505 is adjusted according to the spacing of the reinforcing bars. After the adjustment is completed, the bolt 506 is rotated to lock the buckle 505. 05. Secure the device, then rotate the screw sleeve 503 to release the elastic fixing block 502 from the horizontal slide rod 504. Then pull the horizontal slide rod 504, which slides inside the horizontal bar 501. Adjust the horizontal slide rod 504 to align the buckle 505 with the rebar. Then rotate the screw sleeve 503 to retract the elastic fixing block 502 and lock the horizontal slide rod 504. Then put the rebar into the buckle 505 and proceed with the hoisting of the next layer of precast wall. Fit the protruding rebar into the pre-drilled hole in the wall during hoisting, remove the device, and slowly lower the precast wall to complete the hoisting.
[0021] Please see Figure 5 In this embodiment, the adjustment assembly includes a stepless wheel 601. A stepless wheel 601 is disposed on one side of the vertical slide rod 3. A limitless position block 602, which restricts the rotation of the stepless wheel 601, is disposed on one side of the stepless wheel 601. The limitless position block 602 is rotatably connected to the vertical slide rod 3. A spring 603 is disposed inside the limitless position block 602. A rotating rod 604 is fixedly connected to one side of the stepless wheel 601. A gear 605 is disposed on the outer side of the rotating rod 604. A toothed plate 606 is disposed on the inner side of the vertical rod 2. The gear 605 meshes with the toothed plate 606. The vertical slide rod 3 and the rotating rod 604 are respectively provided with grooves. The rotating rod 604 is rotatably connected inside the groove of the vertical slide rod 3. The grooves at the corresponding positions of the vertical slide rod 3 and the rotating rod 604 provide a limiting effect when the rotating rod 604 rotates inside the groove. The vertical rod 2 and the gear 605 are respectively provided with grooves. The gear 605 is movably connected inside the groove of the vertical rod 2. The grooves at the corresponding positions of the vertical rod 2 and the gear 605 provide a limiting effect when the gear plate 606 moves inside the groove.
[0022] During operation, this device is placed at the protruding steel bars of the precast wall on the floor slab. By pressing the limitless position block 602, the limitless position block 602 compresses the spring 603, releasing the limiting fixation on the endless wheel 601. Then, the vertical slide rod 3 is pulled, and the vertical slide rod 3 slides outside the vertical rod 2. The vertical slide rod 3 drives the rotating rod 604, which in turn drives the gear 605 to rotate along the toothed plate 606. The gear 605 drives the rotating rod 604 to rotate, which in turn drives the endless wheel 601 to rotate. When adjusted to the appropriate position, the limitless position block 602 is released. The spring 603 loses pressure and causes the limitless position block 602 to rebound, thus limiting and fixing the endless wheel 601. Then, the bolt 506 is rotated to release the limitless wheel 601. After limiting the position of the buckle 505, push the buckle 505 to slide outside the horizontal slide bar 504. Adjust the spacing of the buckles 505 according to the spacing of the reinforcing bars. After the adjustment is completed, rotate the bolt 506 to fix the buckle 505. Then rotate the sleeve 503 to release the elastic fixing block 502 from fixing the horizontal slide bar 504. Then pull the horizontal slide bar 504 and slide it inside the horizontal bar 501. Adjust the horizontal slide bar 504 to align the buckle 505 with the position of the reinforcing bar. Then rotate the sleeve 503 to retract the elastic fixing block 502 and lock the horizontal slide bar 504. Then put the reinforcing bar into the buckle 505 and carry out the hoisting of the next layer of precast wall. Fit the pre-reserved hole of the wall during hoisting into the extended reinforcing bar, remove the device, and slowly lower the precast wall to complete the hoisting.
[0023] Through the above steps, by rotating bolt 506, the limit on buckle 505 is released, and then buckle 505 is pushed to slide outside of horizontal slide bar 504. The spacing of buckle 505 is adjusted according to the spacing of reinforcing bars. After adjustment, bolt 506 is rotated to fix buckle 505. Then, screw sleeve 503 is rotated to release the elastic fixing block 502 from fixing horizontal slide bar 504. Then, horizontal slide bar 504 is pulled and slides inside horizontal bar 501. The horizontal slide bar 504 is adjusted to align buckle 505 with reinforcing bar position. Then, screw sleeve 503 is rotated to retract elastic fixing block 502 and lock horizontal slide bar 504. Then, reinforcing bar is placed into buckle 505, and the next layer of precast wall is hoisted. The pre-reserved hole of the wall during hoisting is fitted with the protruding reinforcing bar, the device is removed, and the precast wall is slowly lowered to complete the hoisting.
