Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structures, and in particular to a positioning device for the foundation steel columns of a steel structure factory building. Background Technology
[0002] When installing steel columns on the cup-shaped foundation of a large factory building, gaps exist between the steel column and the surrounding area of the cup-shaped foundation. Temporary fixing is required before adjustment during hoisting. Currently, steel wedges are commonly used for fixing, followed by manual adjustment and fixation by hammering the wedges with a sledgehammer. See utility model patent application number 2016210436435, which discloses a cup-shaped foundation box-shaped steel column and its installation, adjustment, and fixing device that uses a sledgehammer method. The sledgehammer strikes the wedge-shaped limiting structure, causing it to impact and embed into the gap between the cup-shaped foundation box-shaped steel column and the inner wall of the concrete cup-shaped foundation. The column position and fixation are adjusted by the embedding depth of the first wedge-shaped limiting structure. This installation method has the problem of inaccurate control of the adjustment amount, requiring repeated adjustments, and can damage the anti-corrosion coating and base material of the steel column. There is also the risk of the hammer falling off and injuring workers, posing a safety hazard. Utility Model Content
[0003] To solve the above problems, this utility model proposes a positioning device for the foundation steel columns of a steel structure factory building.
[0004] The technical solution of this utility model is: a positioning device for steel columns of steel structure factory foundation, including a V-shaped steel component and a jacking screw. The V-shaped steel component includes an inner plate and an outer plate fixedly connected at their lower ends. The inner plate and the outer plate are the same size. The two plates are bent or welded together at their lower ends. One end of the jacking screw is fixed to the inner side of the upper part of the inner plate. The jacking screw is welded to the inner plate. A through hole is provided in the upper part of the outer plate. The outer end of the jacking screw extends out from the through hole. The size of the through hole is larger than the cross-sectional size of the jacking screw. An adjusting nut is provided on the jacking screw inside the outer plate. A washer is provided between the adjusting nut and the outer plate.
[0005] Preferably, a locking nut is provided on the push screw on the outer side of the outer plate, and a washer is provided between the locking nut and the outer plate.
[0006] Preferably, the upper part of the inner plate is provided with an inner folding plate, and the pushing screw is connected to the inner folding plate. The upper part of the outer plate is provided with an outer folding plate parallel to the inner folding plate. The inner folding plate and the outer folding plate have the same size, and the through hole is set in the middle of the outer folding plate.
[0007] Preferably, the through hole is an oblong hole, the length direction of which is consistent with the length direction of the outer plate, and the push screw has a certain amount of room for movement within the oblong hole.
[0008] Preferably, several V-shaped steel components are evenly inserted into the gap formed between the steel column and the tapered groove of the foundation. Two V-shaped steel components are inserted into the gap on each side. The push screw at the upper end of the V-shaped steel component is located above the foundation. The adjusting nut on the push screw can be easily tightened by a wrench.
[0009] Preferably, the width of the V-shaped steel member is smaller than the spacing between the studs at the bottom of the steel column to ensure smooth assembly.
[0010] The beneficial technical effects of this utility model are:
[0011] The V-shaped steel component of this positioning device can be fitted into the gap between the steel column and the conical groove. By adjusting the combination of the nut and the push screw, the V-shaped steel component can be driven to open outward, thereby embedding and fixing the steel column. It has the advantages of simple structure and easy processing and manufacturing. It can easily and accurately complete the positioning of the foundation and steel column, effectively solving the problems of inaccurate control of adjustment amount, low construction accuracy, easy damage to the parent material and poor safety in traditional construction.

[0019] Example 1, see appendix Figure 1-6A positioning device for steel columns in the foundation of a steel structure factory building includes a V-shaped steel component 1 and a jacking screw 2. The V-shaped steel component includes an inner plate 11 and an outer plate 12 fixedly connected at their lower ends. The two plates of the V-shaped steel component 1 have a certain elasticity. One end of the jacking screw 2 is fixed to the inner side of the upper part of the inner plate 11. A through hole 13 is provided on the upper part of the outer plate 12. The outer end of the jacking screw 2 extends out of the through hole and can slide freely in the through hole 13. The size of the through hole 13 is larger than the cross-sectional size of the jacking screw 2, so that the jacking screw 2 has a certain amount of movement in the through hole 13. An adjusting nut 3 is provided on the jacking screw 2 on the inner side of the outer plate 12. Rotating the adjusting nut can push the outer plate 12 outward, driving the inner plate 11 and the outer plate 12 to deform outward synchronously. A locking nut 4 is provided on the jacking screw 2 on the outer side of the outer plate.
[0020] Several V-shaped steel components 1 are evenly inserted into the gap formed between the steel column 6 and the conical groove 51 of the foundation 5. The V-shaped steel components 1 provide uniform positioning support for the steel column 6 inside the conical groove 51. The push screw 2 at the upper end of the V-shaped steel component 1 is located above the foundation 5. The width of the V-shaped steel component 1 is smaller than the spacing between the studs 61 at the bottom of the steel column 6, so as to avoid the studs 61 affecting the smooth embedding of the V-shaped steel component 1 into the gap between the steel column 6 and the conical groove 51.
[0021] When using the positioning device in this embodiment, the V-shaped steel component 1 is evenly inserted into the gap between the steel column 6 and the conical groove 51. The V-shaped steel component 1 is initially fixed in the gap by its own elasticity. Then, the adjusting nut 3 is turned with a wrench. The adjusting nut 3 moves along the pushing screw 2 and pushes the outer plate 12 outward. Under the support of the pushing screw 2, the inner plate 11 and the outer plate 12 open outward synchronously and gradually tighten the steel column 6 in the gap. The positioning of the foundation 5 and the steel column 6 is completed simply and accurately (the adjustment accuracy can reach 1mm). This effectively solves the problems of inaccurate control of adjustment amount, low construction accuracy, and easy damage to the parent material in traditional construction.
[0022] Example 2, see appendix Figure 5-6 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the upper part of the inner plate 11 is provided with an inner folding plate 14, and the push screw 2 is connected to the inner folding plate 14. The upper part of the outer plate 12 is provided with an outer folding plate 15 parallel to the inner folding plate 14. The through hole 13 is located in the middle of the outer folding plate 15. The parallel arrangement makes the push screw 2 basically perpendicular to the outer folding plate 15 and the inner folding plate 14. Therefore, the adjusting nut 3 and the locking nut 4 are basically parallel to the surface of the outer folding plate 15, which is conducive to the full contact between the nut and the surface of the outer folding plate 15, increasing its force-bearing area, and ensuring high stability and sufficient thrust during the adjustment process.
[0023] The through hole 13 is an oblong hole, and the length direction of the oblong hole is consistent with the length direction of the outer plate 12. During the positioning adjustment process, as the inner plate 11 gradually presses against the side of the steel column 6, the position of the push screw 2 at its upper end will swing upward accordingly. The oblong hole can accommodate the swing of the push screw 2, avoid jamming, and ensure that the positioning adjustment is carried out smoothly.
