DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] See also Figure 1-3 The utility model provides a technical solution: a positioning device for steel structure beam-column connection construction, comprising a device frame with both top and bottom ends open and rectangular, the middle of both side walls of the device frame are vertically separated to form a front frame body 1 and a rear frame body 2, the middle of the bottom end of the front side wall and the bottom end of the rear side wall of the device frame are vertically opened with a rectangular first overlapping groove 3, the middle of the bottom end of the other two side walls of the device frame are vertically opened with a rectangular second overlapping groove 4, and the heights of the multiple first overlapping grooves 3 and the multiple second overlapping grooves 4 are adapted;

[0020] The middle part of the two ends of the rear side wall surface of the rear frame 2 is transversely penetrated with a mounting opening, the inside of the two mounting openings are transversely fixedly connected with a threaded sleeve 6, the inside of the two threaded sleeves 6 are transversely threadedly connected with a threaded rod 7, the inner ends of the two threaded rods 7 are transversely rotatably connected with a connecting piece, the inner ends of the two connecting pieces and the two ends of the inner surface of the front side wall of the front frame 1 are fixedly connected with a first guide plate 8 arranged along the height direction of the device frame, and the outer surfaces of multiple first guide plates 8 are fixedly connected with a second guide plate 9 that is adapted to its length and arranged perpendicular to each other in the horizontal direction.

[0021] In this embodiment, when the device is in use, the device frame formed by combining the front frame 1 and the rear frame 2 is first placed directly on the lower cross-shaped steel structure, and then the construction personnel lift and lower the upper steel structure by a crane, and send it in from the opening at the top of the device during the lowering process. After sending it in to a certain extent, if the steel structure is not aligned, the construction personnel can rotate the two threaded rods 7 to drive the first guide plate 8 on one side to move toward the first guide plate 8 on the other side. During the movement, the position between the upper and lower steel structures can be adjusted so that the two are aligned with each other. When the aligned steel structures are completely spliced, the staff can extend the welding gun into the interior of the multiple first lap grooves 3 and the multiple second lap grooves 4 to weld the steel structure. After welding is completed, the device is lifted upward and unfolded to be removed. Through this device, the accuracy of steel structure splicing can be guaranteed, and the construction efficiency can be improved, thereby improving the practicality of the device.

[0022] The outer ends of the two threaded rods 7 are fixedly connected with torsion plates, which makes it convenient for the staff to rotate the threaded rods. When welding, since the steel structure is ultimately limited and fixed by multiple first guide plates 8 and multiple second guide plates 9 inside the device, and the first guide plates 8 and multiple second guide plates 9 have a certain thickness, there is a certain distance between the inner edge parts of the first lap groove 3 and the second lap groove 4 and the steel structure. When performing welding operations, the staff do not have to worry about welding the device to the steel structure.

[0023] Furthermore, a hinge 5 is provided on one side of the front frame 1 and the rear frame 2 , and the front frame 1 and the rear frame 2 are hingedly connected to each other via the hinge 5 .

[0024] The other side surface of the rear frame 2 is fixedly connected to a fixing seat 10, the outer end of the fixing seat 10 is laterally rotatably connected to a screw rod 11, the outer surface of the screw rod 11 is threadedly connected to a screw rod sleeve 13, and the same side surface of the front frame 2 is laterally fixedly connected to a snap-in piece 12, and the outer end of the snap-in piece 12 is laterally provided with a U-shaped groove corresponding to and adapted to the screw rod 11.

[0025] In this embodiment, after the screw rod 11 on the rear frame 2 is rotated to the inside of the U-shaped groove of the clamping piece 12, the screw rod sleeve 13 is rotated until the screw rod sleeve 13 is tightly fitted with the clamping piece 12 to form a locking structure, which, together with the hinge 5, can fix the front frame 1 and the rear frame 2 together to ensure that the device frame formed by the two will not fall apart. When the device needs to be removed, the screw rod sleeve 13 is rotated in the opposite direction and the screw rod 11 is pulled out from the inside of the U-shaped groove.

[0026] Furthermore, the outer surface of the screw sleeve 13 is provided with anti-slip grooves.

[0027] In this embodiment, the anti-slip grooves play an anti-slip role, making it easier for people to rotate the screw sleeve 13.

[0028] Furthermore, multiple installation openings are opened transversely at both ends of the rear side wall surface of the rear frame 2 and respectively located at the upper and lower parts of the two threaded sleeves 6. The interiors of the multiple installation openings are fixedly connected to fixed rings 14, and the interiors of the multiple fixed rings 14 are transversely slidably connected to guide rods 15. The multiple guide rods 15 are respectively fixedly connected to the surface of the first guide plate 8 on the same side.

[0029] In this embodiment, the guide rod 15 plays a guiding role, so that the first guide plate 8 connected to the threaded rod 7 will not deflect and always maintain a vertical state.

[0030] Furthermore, the inner surfaces of the plurality of first guide plates 8 and the plurality of second guide plates 9 are all inclined inward from top to bottom.

[0031] In this embodiment, the inner surfaces of the multiple first guide plates 8 and the multiple second guide plates 9 are inclined inward from top to bottom, so that the top opening of the clamping structure composed of the multiple first guide plates 8 and the multiple second guide plates 9 is larger, making it convenient for the upper steel structure to enter the interior of the device.

[0032] The working principle and usage process of the present invention: After the present invention is installed, when the device is used, the device frame formed by combining the front frame 1 and the rear frame 2 is first placed directly on the cross-shaped steel structure at the bottom, and then the construction personnel use a crane to lift and lower the upper steel structure. During the lowering process, it is sent in from the open top of the device. After being sent in to a certain extent, if the steel structure is not aligned, the construction personnel can rotate the two threaded rods 7 to drive the first guide plate 8 on one side to move toward the first guide plate 8 on the other side. During the movement, the position between the upper and lower steel structures can be adjusted so that the two are aligned with each other. When the aligned steel structures are completely spliced, the staff can extend the welding gun into the interior of the multiple first lap grooves 3 and the multiple second lap grooves 4 to weld the steel structures. After welding is completed, the device is lifted upward and unfolded to be removed. Through this device, the accuracy of steel structure splicing can be guaranteed, and the construction efficiency can be improved, thereby improving the practicality of the device.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
