Description

Technical Field

[0001] The invention relates to the technical field of auxiliary positioning for steel column installation in steel structure engineering, in particular to a cup-shaped foundation inserted steel column horizontal positioning device. Background Art

[0002] Cup-mouth foundation inserted steel columns are a type of steel structure connection widely used in industrial and civil buildings. They are particularly suitable for buildings that require rapid assembly, such as single-story factories and warehouses. The core structure is to insert prefabricated steel columns directly into the concrete cup-mouth foundation, and achieve fixation and force transmission through secondary grouting. Currently, the installation of cup-mouth foundation inserted steel columns mostly uses a crane in conjunction with workers to determine the horizontal position of the steel columns by pulling with steel wire ropes.

[0003] Patent number CN219316459U discloses a steel column installation and positioning device comprising multiple positioning assemblies, each comprising a positioning tube surrounding the side wall of the steel column and a positioning piece disposed at the cup opening and corresponding to the positioning tube. The positioning tube is disposed vertically and can be sleeved onto the positioning piece. This technical solution enables more precise positioning of the steel column within the cup opening during installation, while also making installation more convenient and more efficient.

[0004] Patent number CN215715472U is a positioning and height adjustment device for installing a cup-mouth foundation steel column, which includes a cup-mouth foundation and a steel column.

DETAILED DESCRIPTION

[0034] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0035] like Figure 1-11 As shown, a cup-mouth foundation inserted steel column horizontal positioning device includes a cup-mouth foundation base 1, a socket is provided on the upper side of the cup-mouth foundation base 1, a steel column body 2 corresponding to the socket is plugged into the upper side of the cup-mouth foundation base 1, a first assembly piece 3 and a second assembly piece 4 are provided on the upper side of the cup-mouth foundation base 1, a positioning rod 5 is provided on the lower side of the first assembly piece 3 and the second assembly piece 4, the interior of the positioning rod 5 is hollow, a pair of strip grooves 6 are provided on the first assembly piece 3 and the second assembly piece 4, positioning holes are provided on the four corners of the upper side of the cup-mouth foundation base 1, and the lower side of the positioning rod 5 is plugged into the positioning holes.

[0036] A first adjusting frame 7 and a second adjusting frame 8 are respectively provided on the inner sides of the first assembly piece 3 and the second assembly piece 4. A connecting bolt 9 is inserted into the first adjusting frame 7. A connecting nut 10 corresponding to the connecting bolt 9 is embedded on the lower side of the first adjusting frame 7. A first rectangular groove 11 corresponding to the connecting bolt 9 is opened on the second adjusting frame 8. A second rectangular groove 12 corresponding to the connecting bolt 9 is opened on the first assembly piece 3 and the second assembly piece 4.

[0037] An external thread is provided on the upper side of the positioning rod 5, and a transmission ring 13 is threadedly connected to the upper side of the positioning rod 5. A pair of corresponding first openings 14 are opened on the upper side of the positioning rod 5, and a transmission frame 15 is provided inside the positioning rod 5. The upper side of the transmission frame 15 extends from the first opening 14, and a transmission block 16 is provided on the lower side of the transmission frame 15. A pair of corresponding second openings 17 are opened on the lower side of the positioning rod 5, and a positioning component corresponding to the second opening 17 is provided inside the positioning rod 5.

[0038] The first adjustment frame 7 is composed of two first U-shaped frames and two first connecting blocks, and the second adjustment frame 8 is composed of two second U-shaped frames and two second connecting blocks. The first connecting block and the second connecting block are respectively slidably connected to a pair of strip grooves 6 opened on the first assembly piece 3 and the second assembly piece 4. A notch is provided on the lower side of the first U-shaped frame, and the second U-shaped frame is plugged into the notch.

[0039] The positioning assembly includes a pair of translation blocks 18 arranged inside the positioning rod 5 , an arc-shaped rough block 19 is arranged outside the translation block 18 , and the pair of translation blocks 18 are connected by a pair of spring rods 20 .

[0040] First guide notches 21 are provided on both sides of the left and right sides of the second opening 17, guide strips 22 corresponding to the first guide notches 21 are provided on both sides of the translation block 18, guide blocks 23 are provided on the upper and lower sides of the second opening 17, and second guide notches 24 corresponding to the guide blocks 23 are provided on the upper and lower sides of the translation block 18 and the arc-shaped rough block 19.

[0041] It should be noted that after the cup-mouth foundation pedestal 1 has been installed and poured on site and its strength has reached more than 70% of the design strength, the on-site staff can process and manufacture the first assembly piece 3, the second assembly piece 4, the first adjustment frame 7 and the second adjustment frame 8 with the same size as the top surface size of the cup-mouth foundation pedestal 1 and the inner diameter matching the steel column body 2 according to the design drawing dimensions, and then weld the pre-processed positioning rod 5 to the lower side of the first assembly piece 3 and the second assembly piece 4, and then measure and lay out the steel column body 2 and the positioning hole position. At this time, use an electric drill to drill four holes with a depth and diameter matching the positioning rod 5. In order to smoothly insert the positioning rod 5 into the positioning hole, the inner diameter of the positioning hole will be slightly larger than the outer diameter of the positioning rod 5. Then use a lifting device to move the steel column body 2 to the vicinity of the cup-mouth foundation pedestal 1;

[0042] Then, the first assembly piece 3 and the second assembly piece 4 are sleeved on the outside of the steel column body 2. The operator can slide the first adjusting frame 7 and the second adjusting frame 8 along the strip groove 6 respectively, so that the first adjusting frame 7 and the second adjusting frame 8 are close to or away from each other, and the distance between the two is matched with the steel column body 2. After that, the operator can insert the connecting bolt 9 on the upper side of the first adjusting frame 7, and pass the lower side of the connecting bolt 9 through the first rectangular groove 11 on the second adjusting frame 8 and the second rectangular groove 12 on the second assembly piece 4. The connecting bolt 9 cooperates with the connecting nut 10 located on the lower side of the first adjusting frame 7 to fix the distance between the first adjusting frame 7 and the second adjusting frame 8 so that the distance between the two matches the steel column body 2, thereby fixing the above components on the lower side of the steel column body 2;

[0043] When inserting the steel column body 2 into the cup-mouth foundation pedestal 1, the installation worker only needs to align the positioning rod 5 with the positioning hole to conveniently and accurately complete the horizontal positioning of the steel column. Since the inner diameter of the positioning hole is slightly larger than the outer diameter of the positioning rod 5, after the positioning rod 5 is plugged into the positioning hole, the positioning hole will shake slightly, resulting in an unstable plugging situation. At this time, the operator can rotate the transmission ring 13. Since the upper side of the positioning rod 5 is provided with an external thread, and the inner side of the transmission ring 13 is threadedly connected to the positioning rod 5, when the transmission ring 13 is rotated, the pushing ring 25 will be driven to descend, and the upper side of the transmission frame 15 extends from the first opening 14, pushing The moving coil 25 can push the adjustment frame down, thereby driving the transmission block 16 to move down. During the descending process, the transmission block 16 will push the two translation blocks 18 to move horizontally, stretch the spring rod 20, and push the arc-shaped rough block 19 to extend from the second opening 17 and tightly adhere to the inner wall of the positioning hole. At this time, the positioning rod 5 and the positioning hole have an interference fit, thereby increasing the tightness of the connection between the positioning rod 5 and the positioning hole, preventing the subsequent device from falling off or shaking. The spacing between the pair of spring rods 20 is greater than the longitudinal width of the transmission block 16, so there will be no motion interference between the transmission block 16 and the pair of spring rods 20;

[0044] After the positioning rod 5 is fully inserted into the positioning hole, the exposed length is ≥5cm, and the first opening 14 is located in the exposed part, so the part of the transmission rod extending from the first opening 14 will not interfere with the positioning hole, and the first guide notch 21, the guide bar 22, the guide block 23 and the second guide notch 24 cooperate to increase the stability of the arc-shaped rough block 19 and the translation block 18, and increase the plug-in effect of the positioning rod 5 and the positioning hole; a pushing ring 25 is provided on the lower side of the transmission ring 13 to increase the transmission effect between the transmission ring 13 and the transmission frame 15.

[0045] A limit plate 26 is provided on the upper side of the positioning rod 5 to limit the position of the transmission ring 13. A guide rod 27 is provided inside the positioning rod 5. The upper side of the guide rod 27 passes through the transmission block 16 and is plugged into the lower side of the transmission rod to prevent the transmission block 16 and the transmission frame 15 from shaking.

[0046] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
