Description

Technical Field

[0001] This utility model relates to the field of pre-embedding technology for steel structure anchor bolts in construction sites, specifically to a rapid positioning device for pre-embedding steel structure anchor bolts. Background Technology

[0002] In the foundation construction of steel structure workshops, the foundation and short column construction must be carried out before the steel columns are installed. At the same time, in order to ensure the accuracy of the steel structure installation, anchor bolts need to be pre-embedded during the short column construction. The accuracy of the anchor bolt installation will affect the installation quality of the upper steel columns.

[0003] In conventional anchor bolt installation, positioning plates are used. These plates are placed directly above the stirrups of the short column, and the height is controlled by moving the stirrups. Alternatively, square timber is placed below the positioning plate to control the height. This method is slow in positioning the anchor bolts. Furthermore, during concrete pouring, the impact of the concrete and the vibration during compaction can easily cause the lower part of the anchor bolts to shift or deform, affecting the accuracy and verticality of the top of the embedded bolts. This will ultimately affect the installation quality of the upper steel structure. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a rapid positioning device for pre-embedding anchor bolts in steel structures. It enables rapid and accurate positioning and installation of anchor bolts, and avoids the problem of displacement or deformation of the lower part of the anchor bolts due to concrete pouring.

[0005] To achieve the above technical objectives, this utility model proposes the following technical solution: a quick positioning device for pre-embedding anchor bolts in steel structures, comprising a foundation pad, an upper support, and a lower support. The upper and lower supports are connected by a screw, and an adjusting nut is threaded onto the screw. Two parallel support rods are connected to the top of the upper support through a U-shaped piece. A positioning plate is provided on the support rod, and multiple anchor bolt holes are opened on the positioning plate. An anchor bolts are installed in the anchor bolt holes, and a fixing component is provided at the bottom of the anchor bolts.

[0006] Furthermore, both the upper and lower supports are grid-like frames welded together from four steel pipes and four round pipes, with the two ends of the screws fitted inside the steel pipes of the upper and lower supports.

[0007] Furthermore, a circular universal level is provided in the middle of the positioning plate surface.

[0008] Furthermore, the U-shaped part has a round hole, the steel pipe is placed in the round hole, the support rod is placed in the U-shaped part, and the bottom of the U-shaped part has a set screw to tighten the support rod.

[0009] Furthermore, the fixing component includes positioning sleeves respectively fitted onto the anchor bolts, with two adjacent positioning sleeves connected by positioning rods, and an L-shaped fixing rod fixed to the middle of each of the two opposing positioning rods, with the bottom of the L-shaped fixing rod set on the foundation pad.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: by adjusting the position of the anchor bolts by adjusting the movement of the positioning plate in the vertical and horizontal directions through the screw, adjusting nut and U-shaped part, the accuracy of the positioning and installation of the anchor bolts can be ensured; by positioning the upper and lower parts of the anchor bolts respectively by the positioning plate and fixing components, the phenomenon of anchor bolts shifting or deforming during concrete pouring and vibration can be avoided; after installation, the upper bracket, positioning plate and other structures can be removed to achieve the purpose of reuse.

[0016] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figure 1-4 As shown, this utility model provides a quick positioning device for pre-embedding anchor bolts in steel structures, including a foundation pad 1, an upper support 2 and a lower support 3. The upper support 2 and the lower support 3 are connected by a screw 4. An adjusting nut 5 is threaded onto the screw 4. Two parallel support rods 7 are connected to the top of the upper support 2 by a U-shaped piece 6. A positioning plate 8 is provided on the support rod 7. Multiple anchor bolt holes 9 are opened on the positioning plate 8. An anchor bolts 10 are installed in the anchor bolt holes 9. A fixing component 11 is provided at the bottom of the anchor bolts 10.

[0018] like Figure 1 and 2 As shown, the number of anchor bolt holes 9 is determined according to the number and specifications of the pre-embedded bolts 10, and is opened at corresponding positions on the positioning plate 8. The positioning plate 8 is fixed to the upper bracket 2 by the support rod 7 and the U-shaped piece 6. By adjusting the plane position of the positioning plate 8 on the upper support rod 2, the overall position of the anchor bolt holes 9 is determined, thereby achieving the positioning of the pre-embedded positions of the anchor bolts 10. The positioning of the anchor bolts 10 is more accurate and faster. By adjusting the nut 5 and the screw 4, the distance between the upper bracket 2 and the lower bracket 3 is adjusted, so that the positioning plate 8 can move in the vertical direction, which is indirectly used to adjust the levelness of the positioning plate 8. The support rod 7 is fixed to the bottom of the positioning plate 8, and the support rod 7 fixes the positioning plate 8 to the upper bracket 3 by the U-shaped piece 6. During installation, the upper bracket 2 and the lower bracket 3 are first connected by... Bolt 4 and adjusting bolt 5 are installed together and then fitted onto the outer perimeter of the foundation steel cage of anchor bolt 10. Anchor bolt 10 is fixed in the anchor bolt hole 9 of positioning plate 8 with two nuts. Support rod 7 is then fixed to upper bracket 3 with U-shaped part 6. The level of positioning plate 8 is adjusted by adjusting bolt 5. After the level is adjusted, the lower part of anchor bolt 10 is fixed to foundation pad 1 by fixing component 11. Compared with conventional anchor bolt pre-embedded positioning, this utility model has the characteristics of simple manufacturing and installation, convenient use, and reusable materials, which greatly improves the efficiency of steel structure anchor bolt 10 pre-embedded positioning. At the same time, it avoids the problem of the lower part of anchor bolt 10 being offset or deformed by concrete pouring, which would affect the installation quality of steel column.

[0019] The upper support 2 and the lower support 3 are both grid-like frames welded together by four steel pipes 12 and four round pipes 13. The two ends of the screw 4 are fitted inside the steel pipes 12 of the upper support 2 and the lower support 3.

[0020] like Figure 1As shown, during fabrication, four steel pipes 12, each 48.3cm in diameter, 3mm thick, and 0.95m long, are used. These pipes are cut at 0.3m intervals into four 0.65m long pieces and four 0.3m long pieces. The four 0.65m long steel pipes 12 are then welded to two 0.9m long circular pipes 13 and two 1.2m long circular pipes 13 to form a grid-like support structure. After fabrication, adjacent circular pipes 13 and steel pipes 12 are braced diagonally using 19mm diameter steel bars. Reinforcement: Four steel pipes 12 with a length of 0.3m are welded to two round pipes 13 with a length of 0.9m and two round pipes 13 with a length of 1.2m to form a grid support. After the support is made, it is reinforced with steel bars with a diameter of 19mm by diagonal bracing. A screw rod 4 with a length of 0.5m and a diameter of 0.38m with double adjusting nuts 5 is inserted into the top of the steel pipe 12 with a length of 0.65m and the bottom of the steel pipe 12 with a length of 0.3m, thus forming a quick positioning support. The installation and disassembly of this utility model are relatively simple.

[0021] A circular universal level 14 is provided in the middle of the surface of the positioning plate 8.

[0022] like Figure 1 As shown, the circular universal spirit level 14 is used to detect the levelness of the positioning plate 8.

[0023] The U-shaped part 6 has a circular hole 15, a circular tube 13 is placed inside the circular hole 15, a support rod 7 is placed inside the U-shaped part 6, and a set screw 16 is provided at the bottom of the U-shaped part 6 to tighten the support rod 7.

[0024] like Figure 1 and 3 As shown, during the fabrication of the upper bracket 3, the horizontal circular tube 13 of the upper bracket 2 is inserted into the circular hole 15 of the U-shaped part 6. The U-shaped part 6 can slide on the circular tube 13, thereby causing the positioning plate 8 to move in the horizontal direction of the upper bracket 2. During installation, the two ends of the support rod 7 can be inserted into the U-shaped parts 6 of the two opposing circular tubes 13 of the upper bracket 2, and the two ends of the support rod 7 can be fixed to the circular tube 13 by the set screw 16 to prevent the support rod 7 from causing the anchor bolt 10 to shift when pouring concrete.

[0025] The fixing component 11 includes positioning sleeves 17 respectively fitted onto the anchor bolts 10. Two adjacent positioning sleeves 17 are connected by positioning rods 18. An L-shaped fixing rod 19 is fixedly connected to the middle of the two opposing positioning rods 18. The bottom of the L-shaped fixing rod 19 is set on the foundation pad layer 1.

[0026] like Figure 1As shown, the L-shaped fixing rod 19 is fixed to the foundation pad 1 by bolts, and the positioning sleeve 17 is fitted onto the anchor bolt 10 to fix the bottom of the anchor bolt 10, so as to prevent the lower part of the anchor bolt 10 from shifting when pouring concrete, which would affect the installation quality of the steel column.

[0027] Operating principle: The operation steps are as follows: First, the lower support 3 and the upper support 2 are sequentially mounted on the steel cage at the top of the foundation pad 1 and connected by bolts 4, so that the bottom of the lower support 3 is fixed to the outer periphery of the foundation pad 1; then, the fixing component 11 is mounted on the anchor bolts 10, specifically so that the positioning sleeves 17 are mounted on the anchor bolts 10 one by one, and the upper end of the anchor bolts 10 is installed on the anchor bolt holes 9 of the positioning plate 8 through two nuts; then, the two ends of the support rod 7 are respectively inserted into the U-shaped parts 6. With the help of measuring instruments, the position of the U-shaped parts 6 on the round tube 13 is adjusted to meet the design and specification requirements. After adjusting the position of the U-shaped parts 6... The positioning plate 8 is indirectly adjusted to a horizontal position, and then the top screw 16 is turned to fix the support rod 7 to the round tube 13. Then, under the action of the circular universal spirit level 14, the positioning plate 8 is adjusted to a horizontal state by adjusting the bolt 5 according to the circular universal spirit level 14. Then, the L-shaped fixing rod 19 is fixed to the foundation pad 1 to complete the positioning of the anchor bolt 10. After the concrete is poured, the anchor bolt 10 is removed from the positioning plate 8. Then, the upper support 2 and the lower support 3 are removed and lifted out from the top of the steel cage. The upper support 2 and the lower support 3 are connected by bolts 4, which makes disassembly relatively convenient and also achieves the purpose of reuse.
