Description

Technical Field

[0001] The utility model relates to the field of profiled steel lattice columns, in particular to a profiled steel lattice column convenient for hoisting. Background Technique

[0002] The profiled steel lattice column is simply called a lattice column, and its cross-section is generally designed as a double-axisymmetric or single-axisymmetric cross-section of profiled steel or steel plates. It has a wide range of uses in the construction process. Currently, in the construction process, the profiled steel lattice column is generally lifted by a crane to above the pile hole and lowered into the hollow, and then concrete is poured into the pile hole to form a reinforced concrete column.

[0003] According to the Chinese patent with the publication number CN211499474U, a profiled steel lattice column convenient for hoisting is disclosed. During the hoisting process of the profiled steel lattice column, there is no need to directly contact the profiled steel lattice column. Therefore, the profiled steel lattice column will not be involved and will not be damaged to the profiled steel lattice column body, which has strong practicability.

[0004] Regarding the above-mentioned disclosed patent content, when welding the profiled steel lattice column, it is necessary to fit two profiled steel lattice columns together to weld the contact part. However, since it is difficult to position the two profiled steel lattice columns after fitting, if the profiled steel lattice column shifts during the welding process, it will affect the welding accuracy, thereby reducing the welding efficiency of the two profiled steel lattice columns. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a profiled steel lattice column convenient for hoisting to solve the technical problem that it is difficult to position the two profiled steel lattice columns after fitting, thereby reducing the subsequent welding efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A profiled steel lattice column convenient for hoisting, including four angle steels. A second threaded hole is opened inside the angle steel. A threaded column is threadedly connected in the second threaded hole, and a positioning column is installed at the bottom end of the threaded column. A cross groove is opened at the end of the positioning column.

[0007] By adopting the above technical solution, when the positioning column is removed from the inside of the second threaded hole, the upper part of the second threaded hole will be exposed. At this time, it is convenient to dock multiple lattice columns.

[0008] Further, two first threaded holes are opened at the top of the angle steel, and a mounting plate is installed at the top of the angle steel through a locking bolt.

[0009] By adopting the above technical solution, the setting of the first threaded hole facilitates the screwing of the locking bolt, and thus the mounting plate and the lifting ring can be installed and fixed.

[0010] Further, the locking bolt is threadedly connected to the inside of the first threaded hole, and a plug post is fixed on the mounting plate.

[0011] By adopting the above technical solution, the arrangement of the plug post facilitates the installation of the mounting plate, and after the locking bolt is screwed into the first threaded hole, the mounting plate can be fixed.

[0012] Further, a lifting ring is installed at the top end of the plug post.

[0013] By adopting the above technical solution, the arrangement of the lifting ring facilitates the hoisting of the lattice column.

[0014] Further, a plurality of outer reinforcing plates are installed between the four angle steels.

[0015] By adopting the above technical solution, the arrangement of the outer reinforcing plates facilitates the stable connection of the four angle steels together to form a lattice column.

[0016] Further, an anti-rust paint layer is provided on the outer wall, inner wall of the angle steel and the outer wall of the outer reinforcing plate.

[0017] By adopting the above technical solution, the arrangement of the anti-rust paint layer can prevent the angle steel and the outer reinforcing plate from rusting.

[0018] Further, the plug post is located inside the second threaded hole, and the bottom end of the plug post contacts the top end of the threaded post.

[0019] By adopting the above technical solution, after the plug post is inserted into the second threaded hole, the mounting plate can be positioned.

[0020] Further, the sum of the lengths of the threaded post and the positioning post is the same as the depth of the second threaded hole.

[0021] By adopting the above technical solution, so that the threaded post and the positioning post can completely enter the second threaded hole, and the positioning post can also be removed from the second threaded hole.

[0022] In summary, the present utility model mainly has the following beneficial effects:

[0023] The utility model is provided with a threaded post, a second threaded hole, a cross groove and a positioning post. When it is necessary to butt multiple lattice columns, the staff can insert a cross screwdriver into the cross groove, and then rotate the cross screwdriver, so that the positioning post rotates. The positioning post drives the threaded post to rotate. When the positioning post moves out of the second threaded hole, the upper part of the second threaded hole will be exposed, and the length of the positioning post moving out is the depth of the second threaded hole exposed. When the positioning post moves out of the second threaded hole and stops rotating the cross screwdriver, the positioning post on the lattice column can be inserted into the second threaded hole of another lattice column at this time, so as to butt and position multiple lattice columns, so that when welding multiple lattice columns, the lattice columns will not move, improving the welding accuracy between the lattice columns and the welding efficiency.

The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0032] The embodiments of the present utility model will be described below according to its overall structure.

[0033] Embodiment 1:

[0034] A section steel lattice column convenient for hoisting, such as Figures 1-6As shown in the figure, it includes four angle steels 1. A plurality of external reinforcing plates 2 are installed between the four angle steels 1. The arrangement of the external reinforcing plates 2 facilitates firmly connecting the four angle steels 1 together to form a lattice column. Anti-rust paint layers 3 are provided on the outer walls, inner walls of the angle steels 1 and the outer walls of the external reinforcing plates 2. The anti-rust paint layers 3 can prevent the angle steels 1 and the external reinforcing plates 2 from rusting.

[0035] Refer to Figures 1-4 , a second threaded hole 11 is opened inside the angle steel 1. A threaded column 10 is threadedly connected inside the second threaded hole 11, and a positioning column 12 is installed at the bottom end of the threaded column 10. A cross groove 6 is opened at the end of the positioning column 12. When the positioning column 12 is removed from the inside of the second threaded hole 11, the upper part of the second threaded hole 11 will be exposed. At this time, it is convenient to dock multiple lattice columns. The sum of the lengths of the threaded column 10 and the positioning column 12 is the same as the depth of the second threaded hole 11, so that the threaded column 10 and the positioning column 12 can completely enter the second threaded hole 11, and the positioning column 12 can also be removed from the second threaded hole 11.

[0036] Embodiment 2:

[0037] On the basis of the above Embodiment 1, in order to facilitate the hoisting of the lattice column, the following structure is set up.

[0038] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , two first threaded holes 8 are opened at the top of the angle steel 1. An installation plate 4 is also installed at the top of the angle steel 1 through a locking bolt 7. The first threaded holes 8 are provided to facilitate the screwing of the locking bolt 7, and then the installation plate 4 and the lifting ring 5 can be installed and fixed. The locking bolt 7 is threadedly connected inside the first threaded hole 8. An insertion post 9 is fixed on the installation plate 4. The insertion post 9 is provided to facilitate the installation of the installation plate 4. After the locking bolt 7 is screwed into the first threaded hole 8, the installation plate 4 can be fixed. A lifting ring 5 is installed at the top end of the insertion post 9. The lifting ring 5 is provided to facilitate the hoisting of the lattice column. The insertion post 9 is located inside the second threaded hole 11, and the bottom end of the insertion post 9 contacts the top end of the threaded column 10. After the insertion post 9 is inserted into the second threaded hole 11, the installation plate 4 can be positioned.

[0039] The working principle of the present utility model is as follows: First, the outer reinforcing plate 2 is provided to facilitate the firm connection of the four angle steels 1 together to form a lattice column. The anti-rust paint layer 3 is provided to enable the angle steels 1 and the outer reinforcing plate 2 to have an anti-rust effect. When hoisting is required, first insert the cross jack into the cross groove 6, and then rotate the cross jack, so that the positioning column 12 rotates. The positioning column 12 drives the threaded column 10 to rotate. When the positioning column 12 moves out of the second threaded hole 11, the upper part of the second threaded hole 11 will be exposed. Then insert the insertion column 9 on the mounting plate 4 into the upper part of the second threaded hole 11. After insertion, screw the locking bolt 7 into the first threaded hole 8, and thus the installation of the mounting plate 4 and the lifting ring 5 can be completed. Then the lattice column can be hoisted through the lifting ring 5. After hoisting, the locking bolt 7 needs to be screwed out, and the mounting plate 4 and the lifting ring 5 need to be disassembled to facilitate the subsequent butt joint of the lattice column;

[0040] The length by which the positioning column 12 moves out is the depth of the exposure of the second threaded hole 11. When splicing multiple lattice columns, the positioning column 12 on one lattice column can be inserted into the second threaded hole 11 of another lattice column, so as to butt joint multiple lattice columns.
