Description

Technical Field

[0001] The utility model relates to the technical field of assembled steel structures, in particular to a steel-concrete composite column. Background Art

[0002] Steel tube concrete composite columns not only have the characteristics of high strength, good ductility and high fire resistance of steel tube concrete, but also have the advantages of convenient construction. This type of composite column can be hidden inside the wall, so that the inner wall does not have edges, which better meets the use function of the building and has become an important structural system for engineering applications.

[0003] Publication No. CN213390593U discloses a novel connection structure of H-shaped steel concrete composite column and I-shaped steel beam. The H-shaped steel concrete composite column greatly improves the bearing capacity of the column and has good hysteresis characteristics and energy dissipation capacity under low-cycle repeated loads; the H-shaped steel is wrapped with concrete to reduce the corrosion of the steel and make the steel and concrete complement each other; the steel plate with bolt through holes can effectively solve the instability problem caused by the length of the bolt, enhance the fixing effect of the bolt, and the beam-column connection is a bolt connection, which avoids welding deformation and increases the node stiffness; less on-site work, H-shaped steel and I-shaped steel beams can be completely manufactured by steel structure factories, which greatly improves efficiency, but the patent still has the following problems in actual use:

[0004] Although the novel H-shaped steel-concrete composite column and I-beam connection structure reduces the corrosion of the steel by wrapping the concrete around the H-shaped steel, so that the steel and concrete complement each other, the connection between the H-shaped steels is connected by the threaded action between the high-strength bolts and the nuts.

[0030] The working principle of this utility model:

[0031] In the present invention, before using the device, it is necessary to first check the overall condition of the device to ensure that it can work normally. Figures 1 to 5 , first install the first steel section 102 at the specified position. When the length of the first steel section 102 needs to be extended, first weld the first connecting plate 103 to the specified position of the first steel section 102, then press the push rod 109 to drive the spring 110 to compress, and at the same time use the meshing action between the blocking rod 111 and the push rod 109 to make the blocking rod 111 rotate around the limiting column 112, so that the blocking rod 111 can be retracted into the threaded rod 106, and then the threaded rod 106 is inserted into the holes of the first connecting plate 103 and the second connecting plate 104, loosen the push rod 109, and use the restoring force of the spring 110 to drive the blocking rod 111 to reset, and then rotate the first nut 107 to make the first nut 107 and the second connecting plate 104 fit tightly, and use the cooperation between the first nut 107 and the blocking rod 111 to quickly fix the position of the second connecting plate 104, and similarly, the second steel section 105 can be quickly fixed on one side of the second connecting plate 104, and the installation of the second steel section 105 can be completed;

[0032] Secondly, when the position of the baffle needs to be fixed before pouring concrete, the screw rod 202 is first rotated, and the threaded action between the screw rod 202 and the fixing sleeve 201 is utilized to drive the first baffle 204 to move back and forth in the horizontal direction, so as to adjust the distance of the first baffle 204. The threaded action between the bolt 206 and the second nut 207 can be used to fix the position of the L-shaped block 205 on the first baffle 204. The connection effect of the L-shaped block 205 not only facilitates the fixation of the second baffle 208, but also improves the stability between the first baffle 204 and the second baffle 208, thereby preventing the first baffle 204 and the second baffle 208 from being stretched apart when pouring concrete.

[0033] By setting up the installation mechanism 1, the first steel section 102 and the second steel section 105 can be installed quickly, and the disassembly of the threaded rod 106 is convenient, so as to avoid increasing work efficiency due to installation errors. By pressing the push rod 109, the spring 110 is compressed, and the meshing action between the blocking rod 111 and the push rod 109 is utilized so that the blocking rod 111 rotates around the limiting column 112, so that the blocking rod 111 can be retracted into the threaded rod 106, and then the threaded rod 106 is inserted into the holes in the second connecting plate 104 and the second steel section 105, the push rod 109 is loosened, and the blocking rod 111 is driven to reset by the restoring force of the spring 110, and the first nut 107 is rotated so that the first nut 107 and the second connection 104 are tightly fitted, and the position of the second steel section 105 can be quickly fixed by utilizing the cooperation between the first nut 107 and the blocking rod 111.

[0034] By setting up the fixing mechanism 2, the distance between the first baffle 204 and the first steel section 102 can be adjusted according to actual conditions, so as to determine the diameter of the concrete column. By utilizing the threaded action between the screw rod 202 and the fixing sleeve 201, the first baffle 204 is driven to move back and forth in the horizontal direction, so as to adjust the distance of the first baffle 204. By utilizing the threaded action between the bolt 206 and the second nut 207, the position of the L-shaped block 205 on the first baffle 204 can be fixed. The connection effect of the L-shaped block 205 not only facilitates the fixation of the second baffle 208, but also improves the stability between the first baffle 204 and the second baffle 208.
