Description

Technical Field

[0001] This utility model relates to the field of basic engineering technology, specifically to a positioning device for reserved steel bars in the cast-in-place connection layer of prefabricated buildings. Background Technology

[0002] In the construction of cast-in-place concrete structures, the location and distribution of pre-reserved reinforcing bars are crucial to ensuring the overall strength and stability of the structure. In actual construction, it is usually necessary to measure, position, and fix the pre-reserved reinforcing bars to meet the requirements of the design drawings. Currently, construction often employs a combination of manual layout and simple tools, such as using measuring instruments to mark the center line of the reinforcing bar arrangement, then manually adjusting the position of the reinforcing bars, and temporarily fixing them using clamps or tying devices.

[0003] However, these methods often rely on the experience of construction workers and are easily affected by human factors, resulting in insufficient accuracy in the placement of reinforcing bars, especially in the case of large-scale or complex reinforcing bar distribution, where they are inefficient and have large errors. Utility Model Content

[0004] The purpose of this invention is to provide a positioning device for reserved reinforcing bars in the cast-in-place connection layer of prefabricated buildings. By setting up a cross-shaped frame and combining the precise adjustment functions of the transverse and longitudinal sliding components, it can quickly and accurately determine the relative position of the reserved reinforcing bars with respect to the transverse and longitudinal axes of symmetry, thus aligning and positioning the reserved reinforcing bars before pouring. This solves problems such as misalignment between prefabricated components, incorrect connection positions of reserved reinforcing bars, overall misalignment, and the need for secondary modifications, ensuring the positioning accuracy of the reserved reinforcing bars and the quality of concrete pouring. The device is reusable, easy to operate, and can reduce construction costs and shorten the construction period.

[0010] At least two movable adjustment clamps are disposed between the two clamping plates. Each movable adjustment clamp includes two adjustment sleeves respectively fitted on the two clamping plates and a fastening tie rod disposed between the two adjustment sleeves and threadedly connected thereto.

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Please see Figure 1 and Figure 2 A preferred embodiment of this application shows a positioning device for a precast reinforced concrete (6) in a prefabricated building's cast-in-place connection layer, comprising a cross-shaped frame 1, a transverse sliding assembly 2, a longitudinal sliding assembly 3, clamping plates 4, and a movable adjustment fixture 5. The cross-shaped frame 1 includes an X-axis horizontal bar 11 and a Y-axis vertical bar 12 connected to the X-axis horizontal bar 11. The transverse sliding assembly 2 includes a transverse sliding rod 21 that can move laterally along the X-axis horizontal bar 11 and a longitudinal indicator rod 22 vertically arranged on the transverse sliding rod 21. The longitudinal sliding assembly 3 includes a longitudinal sliding rod 31 that can move longitudinally along the Y-axis vertical bar 12 and a transverse indicator rod 32 horizontally arranged on the longitudinal sliding rod 31. The transverse sliding assembly 2 and the longitudinal sliding assembly 3 cooperate to position and align the precast reinforced concrete (6). The two clamping plates 4 are respectively arranged on both sides of the precast reinforced concrete (6). The at least two movable adjustment clamps 5 are arranged between the two clamping plates 4. Each movable adjustment clamp 5 includes two adjustment sleeves 51 respectively fitted on the two clamping plates 4 and a fastening tie rod 52 arranged between the two adjustment sleeves 51 and threadedly connected thereto. The movable adjustment clamps 5 cooperate with the clamping plates 4 to reinforce the reserved steel bars 6 after the position is aligned.

[0027] According to the embodiment of this utility model, by setting a cross-shaped frame 1 and combining the precise adjustment functions of the transverse sliding component 2 and the longitudinal sliding component 3, the relative position of the reserved steel bar 6 with respect to the transverse axis of symmetry 9 and the longitudinal axis of symmetry 10 can be quickly and accurately determined to align and position the reserved steel bar 6 before pouring. This solves problems such as misalignment between assembled components, incorrect connection position of the reserved steel bar 6, overall misalignment, and secondary modifications, ensuring the positioning accuracy of the reserved steel bar 6 and the quality of concrete pouring. The device can be recycled, is easy to operate, and can reduce construction costs and shorten the construction period.

[0028] The following detailed description uses specific examples:

[0029] Please see Figure 1 Both the transverse slide bar 21 and the longitudinal slide bar 31 are equipped with fastening bolts 7, which fix them to the X-axis crossbar 11 and the Y-axis vertical bar 12, respectively. The X-axis crossbar 11 and the Y-axis vertical bar 12 have several threaded holes 13 along their length, with the spacing between adjacent threaded holes 13 being less than the length of the transverse slide bar 21 or the longitudinal slide bar 31. The fastening bolts 7 facilitate the fixation of the transverse slide bar 21 and the longitudinal slide bar 31, while reducing the spacing of the threaded holes 13 allows for the adaptation to different sizes and positions of the pre-reserved reinforcing bars 6, improving the applicability and adjustment accuracy of the device.

[0030] The X-axis crossbar 11 and Y-axis vertical bar 12 are equipped with scales, which can provide intuitive reference data for adjusting the transverse slide bar 21 and the longitudinal slide bar 31, making it easier for operators to quickly and accurately position the slide bars when adjusting them, and further improving the alignment efficiency and accuracy.

[0031] Please see Figure 1 Both the X-axis horizontal bar 11 and the Y-axis vertical bar 12 are provided with sliding grooves 8. The sliding grooves 8 are used to limit the sliding movement of the transverse sliding bar 21 and the longitudinal sliding bar 31 on the X-axis horizontal bar 11 and the Y-axis vertical bar 12, respectively. The cross-section of the sliding groove 8 is an inverted T-shaped structure, which can better limit the sliding range of the transverse sliding bar 21 and the longitudinal sliding bar 31 and prevent the sliding bars from shaking or detaching during the adjustment process.

[0032] Please see Figure 1 The intersection of the X-axis horizontal bar 11 and the Y-axis vertical bar 12 is provided with an origin hole 14. The design of the origin hole 14 helps to quickly align the center point of symmetry during the layout process, ensuring accurate placement of the device and improving the overall alignment effect.

[0033] Please see Figure 2 The adjusting sleeve 51 has a connecting hole at its end, and the fastening tie rod 52 has a thread. The fastening tie rod 52 is threaded to the adjusting sleeve 51 through the connecting hole. This arrangement allows for flexible adjustment of the spacing of the clamping plates 4 by rotating the fastening tie rod 52, and controls the reinforcement force of the reserved reinforcing bars 6, thereby preventing displacement and ensuring the stability of the reinforcing bars.

[0034] The device is used as follows: Before pouring the cast-in-place connection layer, the transverse axis of symmetry 9 and the longitudinal axis of symmetry 10 of the reserved reinforcing bars 6 are measured and laid out. These two axes intersect to form the center point of symmetry for the reserved reinforcing bars 6, providing a reference benchmark for positioning the reserved reinforcing bars 6. The origin hole 14 on the cross-shaped frame 1 is aligned with this center point of symmetry, and the X-axis horizontal bar 11 and the Y-axis vertical bar 12 are arranged along the transverse axis of symmetry 9 and the longitudinal axis of symmetry 10, respectively, to determine the initial placement position and orientation of the device. Subsequently, the transverse sliding component 2 and the longitudinal sliding component 3 are symmetrically adjusted along the X-axis horizontal bar 11 and the Y-axis vertical bar 12 to measure the relative positional relationship between the reserved reinforcing bars 6 and the transverse axis of symmetry 9 and the longitudinal axis of symmetry 10, providing accurate data for subsequent alignment operations. According to the scale on the cross-shaped frame 1, the position of the reserved reinforcing bars 6 is gradually adjusted to complete the alignment of the reinforcing bars. After alignment, two clamping plates 4 are clamped from both sides of the reserved reinforcing bars 6 to fix the reinforcing bars in the correct position. Next, clamping plates 4 are respectively clamped onto two movable adjusting clamps 5, and the tie rods 52 are rotated and tightened to adjust the spacing between clamping plates 4, further tightening and reinforcing the reserved steel bars 6 to ensure the stability and precise position of the reserved steel bars 6 during the pouring process.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
