Description

Technical Field

[0001] This utility model relates to the field of steel structure installation and construction technology, and in particular to a rapid installation device for large lattice columns with cup-shaped foundations. Background Technology

[0002] Currently, large industrial steel structure plants are mostly designed with cup-shaped foundations, which improves structural stability. These projects involve large-scale steel structure engineering with relatively large construction heights and spans. A single steel lattice column can reach a length of 30.2m and a cross-sectional height of 2m. The plates are mostly 28mm thick Q355 steel plates, with a single steel column weighing 20t and a cross-sectional dimension of 2000*200mm. The welds are full-penetration fillet welds and butt welds, with a quality grade requirement of II or higher and high processing precision requirements.

[0003] Technical problems in the installation of steel lattice columns:

[0004] 1. The installation of steel lattice columns requires high precision. Excessive cumulative error in the steel lattice columns will affect the installation of components such as crane beams and steel beams.

[0005] 2. During hoisting, the steel lattice columns cannot be fixed at the rim and bottom of the foundation cup. Initial alignment requires constant adjustment with wedges, making quick and accurate positioning impossible. The operation time of the truck crane is long, posing a significant safety risk.

The lattice column 1 includes: a left limb, a right limb, and several connecting pieces. The left limb and the right limb are fixedly connected by several connecting pieces. Correspondingly, the top of the cup-shaped foundation 11 is provided with two cup-shaped openings, which respectively cooperate with the left limb and the right limb. It also includes: a corbel base plate 2. The front and rear side walls of the left limb and the right limb are respectively provided with four corbel base plates 2 at the same height and symmetrically arranged. The corbel base plates 2 are arranged perpendicular to the side wall of the left limb or the right limb. The corbel base plates 2 are provided with vertical through corbel holes 201.

[0027] In this embodiment, the diameter of the bracket hole 201 is 24mm, and the diameter of the through thread 5 is 20mm. Since the diameter of the bracket hole 201 is slightly larger than that of the through thread 5, it is convenient to quickly complete the initial positioning when installing large lattice columns, thereby improving construction efficiency.

[0028] In this embodiment, it also includes: a corbel plate 3 and a corbel rib plate 4. The corbel base plate 2 is vertically welded and fixed to the side wall of the lattice column 1. Two corbel plates 3 are symmetrically fixed to the left and right sides of the top of the corbel base plate 2. The corbel plate 3 is a right trapezoid. The long side of the trapezoid of the corbel plate 3 is welded and fixed to the side wall of the lattice column 1. The waist side of the corbel plate 3, which is perpendicular to the long side and the short side of the trapezoid, is welded and fixed to the top of the corbel base plate 2. The corbel rib plate 4 is vertically welded to the top of the corbel base plate 2. The left and right ends are welded and fixed to the opposite sides of the two corbel plates 3; the corbel base plate 2 is 375mm long, 270mm wide, and 20mm thick; the corbel plate 3 and corbel rib plate 4 are both 10mm thick, and the distance between the inner end of the corbel rib plate 4 and the outer end of the corbel base plate 2 is 150mm; the corbel base plate 2, corbel plate 3, and corbel rib plate 4 are all made of Q235B material; the corbel plate 3 and corbel rib plate 4 can improve the support strength and stability of the corbel base plate 2.

[0029] In this embodiment, four embedded parts are symmetrically arranged on the front and rear sides of the two cup openings of the cup foundation 11. The embedded parts include: embedded steel plates 9 and embedded anchor bars 10. Four embedded anchor bars 10 are provided in each embedded part. The four embedded anchor bars 10 are symmetrically welded and fixed to the bottom end of the embedded steel plates 9. The embedded steel plates 9 are fixed to the top of the cup foundation 11 by the four embedded anchor bars 10. The top surface of the embedded steel plates 9 is flush with the top surface of the cup foundation 11. Four through-threaded rods 5 are vertically welded to the top of the four embedded steel plates 9 respectively. The embedded steel plates 9 are 200mm long, 200mm wide, and 10mm thick, and are made of Q235B. The embedded anchor bars 10 are made of A12 steel bars. The through-threaded rods 5 are made of Q355B. The embedded steel plates 9 and embedded anchor bars 10 are embedded in the corresponding positions on the top surface of the cup foundation 11 during the construction of the cup foundation 11.

[0030] In this embodiment, the adjustment assembly includes: a nut 6, a washer 7, and a pressure plate 8. The washer 7 and the pressure plate 8 each have a through hole 1 and a through hole 2 respectively. The washer 7 and the pressure plate 8 are respectively located at the bottom and top of the bracket base plate 2. A threaded rod 5 slides through the through hole 1 and the through hole 2 respectively. Two nuts 6 are threadedly connected to the threaded rod 5 at the lower end of the washer 7 and the upper end of the pressure plate 8 respectively. The washer 7 has a length of 190mm, a width of 80mm, and a thickness of 10mm; the pressure plate 8 has a length of 80mm, a width of 80mm, and a thickness of 10mm. Both the pad 7 and the pressure plate 8 are made of Q235B material. When it is necessary to finely adjust the elevation of the lattice column 1 upwards, simply loosen the four nuts 6 at the top clockwise first, and then tighten the four nuts 6 at the bottom clockwise. The four nuts 6 at the bottom will lift the lattice column upwards to the appropriate elevation through the four pads 7. When it is necessary to finely adjust the elevation of the lattice column 1 downwards, simply tighten the four nuts 6 at the bottom counterclockwise. The lattice column 1 will descend to the appropriate elevation position under its own weight. At the same time, the verticality of the lattice column 1 can be finely adjusted by adjusting the four adjustment components.

[0031] The rapid installation process of large lattice columns is as follows: On-site measurement and layout are carried out to mark the installation center line of lattice column 1, and through-threaded rods 5 are welded at the center line position; the perforated brackets and lattice column 1 are processed simultaneously in the factory; after the lattice column 1 arrives and passes the acceptance inspection, hoisting begins. It is hoisted to the cup position, and the four bracket holes 201 are aligned with the four through-threaded rods 5 respectively. The lattice column 1 is then lowered to achieve rapid installation and positioning; then, it is initially fixed by nuts 6, washers 7, and pressure plates 8; then, theodolites and levels are set up in two directions to measure the elevation and verticality; the elevation and verticality of lattice column 1 are finely adjusted and corrected by adjusting the components.
