Description

Technical Field

[0001] The invention discloses a temporary fixing device which is convenient for accurately positioning a steel column and belongs to the technical field of steel high-altitude docking auxiliary devices. Background Art

[0002] Steel-concrete is widely used in large structures with certain seismic requirements due to its high structural bearing capacity, high rigidity, excellent elongation performance and good seismic resistance. The construction process of steel-concrete structures in structures such as high-rise buildings and large bridges often involves the problem of hoisting and docking of steel columns. In order to ensure that the steel-concrete structure is subjected to reasonable force and the subsequent work is carried out smoothly, the installation of steel columns must be accurately positioned. At the same time, due to the large size and weight of prefabricated steel column components, the requirements for high-altitude lifting and aerial position correction are high, and they need to be hoisted in sections and then docked and fixed in the air. After the steel column is hoisted in place in the air, it needs to be temporarily fixed first. The traditional temporary positioning method requires welding a connecting plate on the steel column in advance. After the construction is completed, the connecting plate needs to be destroyed and dismantled and cannot be recycled. In addition, the anti-corrosion performance of the steel column at the dismantling site is reduced, which not only causes a waste of resources, but also increases the difficulty of implementation, reduces the performance of the steel column, and has low positioning accuracy.

[0003] Generally speaking, the existing temporary fixation method of steel column hoisting is inefficient, and workers work at height for a long time, which poses certain safety hazards. In order to improve the efficiency of steel column hoisting and positioning and reduce the risk of high-altitude work, a device that can accurately and quickly position the upper and lower sections of the steel column while facilitating temporary fixation is urgently needed.

DETAILED DESCRIPTION

[0023] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The present invention provides the following embodiments.

[0025] like Figure 1 As shown, the present invention is a temporary fixing device for facilitating accurate positioning of a steel column, comprising a first fixing seat 1, a second fixing seat 2, a third fixing seat 3, a fourth fixing seat 4, a connecting plate 5, a first fixing plate 6, a second fixing plate 7 and a fastening bolt 8;

[0026] like Figure 2As shown, the first fixing seat 1 includes an outer wing plate 9, a web plate 10, an inner wing plate 11, a fixing column 12, a movable plate 13 and a tightening bolt 14, two web plates 10 are vertically fixed at both ends of the outer wing plate 9, and two inner wing plates 11 are respectively vertically fixed to a web plate 10, and there is a gap between the two inner wing plates 11, forming a rectangular frame with an opening, two fixing columns 12 are located at both ends inside the rectangular frame, and the two ends of the fixing columns 12 are respectively fixed on the outer wing plate 9 and the corresponding inner wing plate 11, and the movable plate 13 is provided with a through hole, and a movable plate 13 is slidably installed on each fixing column 12 through the through hole, and two outer wing plate threaded holes 15 are provided on the outer wing plate 9, and two tightening bolts 14 are respectively screwed into one outer wing plate threaded hole 15, and are respectively pressed against a movable plate 13;

[0027] like Figure 1 As shown, the structures of the second fixing seat 2, the third fixing seat 3, and the fourth fixing seat 4 are the same as the structure of the first fixing seat 1, the second fixing seat 2 is located directly below the first fixing seat 1, the third fixing seat 3 is arranged opposite to the first fixing seat 1, the fourth fixing seat 4 is arranged opposite to the second fixing seat 2, and the fourth fixing seat 4 is located directly below the third fixing seat 3, the first fixing seat 1 and the second fixing seat 2 are fixedly connected together by two connecting plates 5, and the third fixing seat 3 and the fourth fixing seat 4 are also fixedly connected together by two connecting plates 5;

[0028] A first fixing plate 6 is fixed on both sides of the first fixing seat 1 and the second fixing seat 2, and a fixing plate threaded hole 16 is opened on the first fixing plate 6. A second fixing plate 7 is fixed on both sides of the third fixing seat 3 and the fourth fixing seat 4, and a through hole is opened on the second fixing plate 7. Four fastening bolts 8 pass through the corresponding through holes on the second fixing plate 7 and are threadedly connected with the fixing plate threaded holes 16 on the first fixing plate 6.

[0029] In the above structure, the movable plate 13 increases the contact area between the tightening bolt 14 and the flange of the steel column, ensuring the clamping effect, thereby ensuring the temporary fixing effect of the present invention. At the same time, the clamping method of the movable plate 13 and the inner wing plate 11 is adopted, so that the present invention can be applied to steel columns of various specifications, as long as the width of the steel column flange can be inserted between the movable plate 13 and the inner wing plate 11.

[0030] The provision of four fastening bolts 8 strengthens the clamping effect of the present invention on the upper and lower steel columns, and further enhances the temporary fixing effect.

[0031] like Figure 3 As shown, the outer wing plate 9 includes two sub-plates, and the two sub-plates are detachably connected together. In this way, the present invention is more convenient to disassemble after the upper and lower sections of the steel columns are permanently fixed.

[0032] The two sub-plates are provided with grooves and convex connecting parts with connecting threaded holes 17, and the two sub-plates are overlapped and spliced ​​together through the grooves and the convex connecting parts, and a plurality of connecting bolts 18 are screwed into the corresponding connecting threaded holes 17 to connect the two sub-plates together. The overlapping splicing design makes the outer wing plate 9 more flat and beautiful.

[0033] The outer wing plate fastening nuts 19 are fixed to both the inner and outer sides of the outer wing plate threaded hole 15, and the inner diameter of the outer wing plate fastening nuts 19 is the same as the inner diameter of the outer wing plate threaded hole 15. The outer wing plate fastening nuts 19 improve the matching force of the outer wing plate threaded hole 15 on the jacking bolt 14, so that the fastening force and fastening effect of the jacking bolt 14 are better.

[0034] A circular positioning plate 20 is fixed to the end of each of the jacking bolts 14, and a circular groove 21 having a diameter adapted to the diameter of the positioning plate 20 is provided at a corresponding position on each movable plate 13. The positioning plate 20 can strengthen the tightening effect of the jacking bolts 14.

[0035] The depth of the groove 21 is half of the thickness of the movable plate 13 , and the thickness of the positioning plate 20 is consistent with the depth of the groove 21 .

[0036] When the tightening bolts 14 are tightened, the positioning plate 20 is pushed to be embedded in the groove 21 of the movable plate 13 , driving the movable plate 13 to move along the fixed column 12 until the flange of the steel column is clamped together with the inner wing plate 11 .

[0037] like Figure 4 As shown, after the upper section steel column 22 is hoisted above the lower section steel column 23, the upper and lower sections of the steel column need to be temporarily fixed first, then permanently fixed, and finally the temporary fixing device is removed. The steel column is an H-shaped steel column.

[0038] like Figure 5As shown, before using the present invention, preparations should be made first, that is, all four fastening bolts 8 should be withdrawn from the corresponding fixing plate threaded holes 16 on the first fixing plate 6, and the movable plates 13 in the first fixing seat 1, the second fixing seat 2, the third fixing seat 3 and the fourth fixing seat 4 should be pushed away from the inner wing plate 11, leaving space for inserting the flange of the steel column. After the preparations are made, the second fixing seat 2 and the fourth fixing seat 4 are inserted from the top of the lower section steel column 23, so that the flange of the lower section steel column 23 is located between the inner wing plate 11 and the movable plate 13, the web is located between the two inner wing plates 11, and inserted into the middle of the connecting plate 5 and the top of the lower section steel column 23, and then the tightening bolts 14 in the second fixing seat 2 and the fourth fixing seat 4 are tightened, so that the positioning plate 20 drives the movable plate 13 to cooperate with the inner wing plate 11 to clamp the flange of the lower section steel, so that the second fixing seat 2 and the fourth fixing seat 4 are fixed to the lower section steel. Then hoist and place the upper section steel column 22. After the flange of the upper section steel column 22 enters between the movable plate 13 and the inner wing plate 11 in the first fixing seat 1 and the third fixing seat 3 and is lowered into place, tighten the tightening bolts 14 in the first fixing seat 1 and the third fixing seat 3 to clamp the flange of the upper section steel column 22. Finally, screw the four fastening bolts 8 into the corresponding fixing plate threaded holes 16 on the first fixing plate 6 to achieve rapid and accurate temporary positioning of the upper and lower section steel columns.

[0039] When the upper and lower steel columns are permanently fixed and disassembled, first remove the connecting bolts 18 on the outer wing plates 9 of the first fixing seat 1, the second fixing seat 2, the third fixing seat 3 and the fourth fixing seat 4, loosen the fastening bolts 8, and then loosen all the top bolts 14, and the upper and lower sections of the steel columns of the present invention can be removed from both sides. The steps are simple and the operation is very convenient.

[0040] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention.
