[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-7 As shown, the rapid positioning and installation device for short columns in steel structure foundations includes: a positioning steel plate 1, a positioning tube 2, and short column reinforcing bars 4.

[0030] The positioning steel plate 1 is provided with a plurality of anchor bolt holes 12 for positioning the anchor bolts 3, the inner wall of the anchor bolt hole 12 is in abutting connection with the anchor bolt 3, the positioning pipe 2 is provided with a plurality of groups and is fixedly connected to the top end of the positioning steel plate 1, the positioning pipe 2 is in communication with the anchor bolt hole 12, the inner wall of the positioning pipe 2 is in abutting connection with the anchor bolt 3, the short column steel bar 4 is arranged at the bottom of the positioning steel plate 1 and the top end thereof is in abutting connection with the positioning steel plate 1, when the short column of the steel structure foundation is installed and constructed, the positioning steel plate 1 is placed on the top end of the short column steel bar 4, the short column steel bar 4 is used for providing the supporting action for the positioning steel plate 1, the anchor bolt hole 12 of the positioning steel plate 1 is aligned with the inner edge of the short column steel bar 4, the anchor bolt 3 is inserted along the inner wall of the anchor bolt hole 12, the inner wall of the anchor bolt hole 12 is in abutting connection with the anchor bolt 3, so that the anchor bolt 3 is positioned, the phenomenon that the anchor bolt 3 is deviated due to improper operation of the construction personnel is avoided, so that the anchor bolt 3 can be accurately positioned after being inserted along the positioning pipe 2, it is not necessary to adjust the position of the anchor bolt 3 again, so that the anchor bolt 3 can be positioned and embedded at one time, then the anchor bolt 3 and the short column steel bar 4 are welded, the positioning steel plate 1 is taken off from the top end of the short column steel bar 4, and finally the concrete is poured on the anchor bolt 3 and the short column steel bar 4, wherein when the anchor bolt 3 is embedded, the anchor bolt 3 and the short column steel bar 4 are first wound by the adhesive tape, so that the anchor bolt 3 and the short column steel bar 4 are preliminarily fixed, when the anchor bolt 3 and the short column steel bar 4 are welded, the adhesive tape is removed.

[0031] Since the thickness size of the positioning steel plate 1 is usually small, in order to improve the positioning effect of the positioning steel plate 1 on the anchor bolt 3, the positioning pipe 2 fixed to the top end of the positioning steel plate 1 can position the anchor bolt 3, when the anchor bolt 3 is embedded, the anchor bolt 3 slides along the inner wall of the positioning pipe 2 and then passes through the anchor bolt hole 12, the positioning pipe 2 and the anchor bolt hole 12 are in communication, so that the path of the inner wall of the anchor bolt hole 12 abutting the anchor bolt 3 is prolonged, and the positioning effect of the positioning steel plate 1 on the anchor bolt 3 is further improved.

[0032] In some specific embodiments, the positioning steel plate 1 is fixedly connected with the limiting plate 5 having a “U” shaped cross section on both sides, the positioning steel plate 1 is fixedly connected with the positioning assembly on both sides perpendicular to the axis of the limiting plate 5, the inner wall of the limiting plate 5 is in abutting connection with the short column steel bar 4, in order to avoid the phenomenon that the positioning steel plate 1 deviates when it is placed on the short column steel bar 4, when the positioning steel plate 1 is placed vertically downward on the short column steel bar 4, the limiting plate 5 fixed to the bottom end of the positioning steel plate 1 slides along the short column steel bar 4, the shape of the limiting plate 5 can ensure that the inner wall of the limiting plate 5 and the short column steel bar 4 abut to provide the limiting action for the positioning steel plate 1.

[0033] In some specific embodiments, the positioning assembly comprises a positioning seat 6, a positioning bolt 8 and a positioning plate 11, the positioning seat 6 is fixedly connected with the bottom end of the positioning steel plate 1, the inner wall of the positioning seat 6 is threadedly connected with the positioning bolt 8, the side end of the positioning bolt 8 is rotationally connected with the positioning plate 11, and the positioning plate 11 is abuttingly connected with the short column steel bar 4. When the anchor bolt 3 and the short column steel bar 4 are welded, the vibration generated by the welding is transmitted to the positioning steel plate 1 through the anchor bolt 3 and the short column steel bar 4, and the limiting plate 5 fixedly connected with the bottom end of the positioning steel plate 1 can vibrate up and down. Therefore, when the positioning steel plate 1 is installed at the top end of the short column steel bar 4, the worker controls the positioning bolt 8 to rotate, the positioning bolt 8 moves through the thread connection with the inner wall of the positioning seat 6, the positioning bolt 8 abuts against the short column steel bar 4 with the positioning plate 11, and the positioning assembly achieves the effect of fixing the positioning steel plate 1 on both sides through abutting against the short column steel bar 4. The distribution mode of the positioning assembly can ensure that the positioning steel plate 1 is limited on all sides.

[0034] In some specific embodiments, the positioning seat 6 is provided with a threaded hole 7 in the direction of the axis, the inner wall of the threaded hole 7 is threadedly connected with the positioning bolt 8, when the positioning bolt 8 rotates, the positioning bolt 8 moves through the thread connection with the inner wall of the threaded hole 7, and when the positioning bolt 8 rotates, the thread connection between the positioning bolt 8 and the threaded hole 7 provides support and fixing for the positioning plate 11.

[0035] In some specific embodiments, the side end of the positioning bolt 8 is provided with a rotating groove 9, the inner wall of the rotating groove 9 is provided with a rotating seat 10 which is rotationally connected with the rotating seat 10, and the side end of the rotating seat 10 is fixedly connected with the positioning plate 11. When the positioning bolt 8 moves, the positioning bolt 8 moves with the positioning plate 11 through the clamping connection between the inner wall of the rotating groove 9 and the rotating seat 10. When the positioning plate 11 abuts against the short column steel bar 4, the positioning bolt 8 stops rotating, and the support and fixing provided by the positioning bolt 8 are transmitted to the positioning plate 11 through the clamping connection between the rotating groove 9 and the rotating seat 10. When the positioning bolt 8 rotates, the rotating groove 9 clamped by the positioning bolt 8 rotates relative to the rotating seat 10, and the worker controls the positioning plate 11 to ensure that the positioning plate 11 does not rotate with the positioning bolt 8, so as to ensure that the positioning plate 11 can abut against the short column steel bar 4.

[0036] In some specific embodiments, the positioning plate 11 has a "U" shape in cross section, and when the positioning plate 11 abuts against the short column steel bar 4, the shape of the positioning plate 11 can ensure that the positioning plate 11 abuts against the short column steel bar 4 on both sides, so as to transmit the abutting to the positioning steel plate 1 through the positioning assembly, and further provide limiting action for the positioning steel plate 1 in the direction perpendicular to the axis of the positioning assembly.

[0037] The above several embodiments of the present application are described in detail, but the embodiments of the present application are not limited to this, and cannot be considered to limit the implementation scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
