Description

Technical Field

[0001] The utility model relates to the technical field of building component connection, in particular to a steel column connection structure. Background Art

[0002] At present, steel structure is a structure mainly composed of steel materials. It is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. The components or parts are usually connected by welds, bolts or rivets. For example, the patent document with application number CN202220995605.9 discloses a connection structure for supporting steel columns. By setting a fixed plate, a sliding groove, a movable plate and a threaded column, it is convenient to place supporting steel columns of different thicknesses, prevent gaps between the supporting steel columns and the connection structure, and improve the stability of the installation.

[0003] However, in similar solutions mentioned above, when the steel columns are subjected to external forces such as vibration and torsion, the connection structure is subjected to external forces in multiple directions, and the plastic deformation capacity of the weld itself is poor, which leads to fractures at the connection, resulting in poor seismic resistance. In addition, the crossbeam is fixed with only two sets of reinforcement ribs, resulting in a weak bearing capacity of the crossbeam, which makes it easy to collapse when encountering special circumstances.

[0004] Therefore, in view of this, the shortcomings of the existing structure were studied and improved, and a steel column connection structure was proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a steel column connection structure, which solves the above-mentioned similar solutions proposed in the above-mentioned background technology. When the steel column is subjected to external forces such as vibration and torsion, the connection structure is subjected to external forces pulling in multiple directions, and the plastic deformation capacity of the weld itself is poor, which leads to fracture at the connection, resulting in poor seismic resistance, and the crossbeam is fixed only by two sets of reinforcement ribs, resulting in weak bearing capacity of the crossbeam, which leads to the problem of easy collapse when encountering special circumstances.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a steel column connection structure, comprising a vertical steel column, a buffer assembly and a connection assembly, a base is fixed at the bottom of the vertical steel column, and the buffer assembly is located at the upper end of the base, and the buffer assembly comprises a fixing ring, a buffer, a support spring and a hinge seat, the outer side of the vertical steel column is slidably connected with the fixing ring, and a plurality of groups of hinge seats are fixed to the outer side of the fixing ring, and the lower end of the hinge seat is hinged with the buffer, two groups of support springs are engaged with the inner side of the buffer, and the connection assembly is located at the upper end of the vertical steel column, and the connection assembly comprises a connecting block, a limiting groove, a first fixing plate and a second fixing plate, the upper end of the vertical steel column is penetrated by the connecting block, and three groups of limiting grooves are penetrated by the outer side of the connecting block, and four groups of the first fixing plates are symmetrically arranged on the left and right sides of the limiting groove, and the lower end face of the connecting block is bolted to the second fixing plate.

[0007] Furthermore, the base is made of reinforced concrete pavement, and four groups of hinged seats are fixed around the upper end of the base.

[0008] Furthermore, four groups of the buffers are arranged around, and a rubber block is slidably connected to the center of the buffer, and a piston is connected to the outside of the support spring.

[0009] Furthermore, a fixing protrusion is fixed on the inner side of the fixing ring, and two groups of the supporting spring and the piston are symmetrically arranged with respect to the rubber block.

[0010] Furthermore, a crossbeam is inserted into the outer side of the connecting block, a damping pad is bonded to the inner side of the limiting groove, and the outer side of the damping pad is in contact with the outer side of the crossbeam.

[0011] Furthermore, the first fixing plate and the second fixing plate are both L-shaped steel plates, and the upper and lower sides of the first fixing plate are in contact with the inner side of the crossbeam.

[0012] The utility model provides a steel column connection structure, which has the following beneficial effects:

[0013] It can be achieved that when the connection structure is subjected to external forces in multiple directions, the plastic deformation capacity between the components can be improved, thereby avoiding fracture at the connection, improving the seismic resistance, and strengthening the connection strength between the beam and the vertical steel column, thereby improving the bearing capacity of the beam, resulting in the collapse of the beam due to overload. The specific contents are as follows:

[0014] By inserting the fixing ring on the outside of the vertical steel column, when the vertical steel column is pulled by external force, it can drive the internal piston to compress the support spring, so that the rubber block deforms, generates heat through friction and absorbs seismic energy, which is beneficial to improve the seismic resistance. By fitting the connecting block with the inner side of the beam and the vertical steel column, its support for shear force can be strengthened, and the beam can be further fixed and supported by several groups of first fixing plates, which is beneficial to avoid the collapse of the beam.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0021] like Figures 1 to 4As shown, the steel column connection structure includes a vertical steel column 1, a buffer component 3 and a connection component 5. A base 2 is fixed below the vertical steel column 1. The material of the base 2 is a reinforced concrete pavement, which is beneficial to improving the firmness of the base 2. The buffer component 3 is located at the upper end of the base 2, and the buffer component 3 includes a fixing ring 301, a buffer 302, a support spring 303 and a hinge seat 304. The outer side of the vertical steel column 1 is slidably connected with a fixing ring 301, and the inner side of the fixing ring 301 is fixed with a fixing protrusion 311, which can provide support for the inner side of the vertical steel column 1, improve the shear force resistance of the vertical steel column 1, and reduce the number of limiting holes at its bottom, which is beneficial to improving its support. The fixing ring 301 is fixed with a plurality of groups of hinge seats 304, and the lower end of the hinge seat 304 is hinged with a buffer 302, and the upper end of the base 2 is surrounded and fixed with four groups of hinge seats 304, so that the buffer Both ends of the buffer 302 are connected with hinge seats 304, and the hinge seats 304 enable the vertical steel column 1 to move between internal components, thereby improving the plastic deformation capacity of the device and preventing the connecting bolts from loosening. Two groups of support springs 303 are engaged on the inner side of the buffer 302 to buffer the mechanical energy and reduce the damage of the vertical steel column 1. Four groups of buffers 302 are arranged around, and a rubber block 321 is slidably connected to the inner center of the buffer 302 to absorb shock energy and reduce vibration. The outer side of the support spring 303 is connected to a piston 322, and two groups of support springs 303 and pistons 322 are symmetrically arranged about the rubber block 321. The shock energy is transmitted to the rubber block 321 through the piston 322 and the support spring 303, and the rubber block 321 absorbs energy and reduces shock, thereby improving the plastic deformation capacity between the components, thereby avoiding fracture at the connection and improving the anti-seismic ability.

[0022] The connecting component 5 is located at the upper end of the vertical steel column 1, and the connecting component 5 includes a connecting block 501, a limiting groove 502, a first fixing plate 503 and a second fixing plate 504. The upper end of the vertical steel column 1 is penetrated by a connecting block 501, and a crossbeam 4 is inserted on the outer side of the connecting block 501 for connecting the crossbeam 4 and the vertical steel column 1, which is beneficial to further improve the support of the vertical steel column 1 for shear force, and three groups of limiting grooves 502 are penetrated on the outer side of the connecting block 501, and a damping pad 521 is bonded on the inner side of the limiting groove 502, and the outer side of the damping pad 521 is fitted with the outer side of the crossbeam 4, so that when vibrated, the crossbeam 4 and the damping pad 521 rub against each other, thereby further absorbing energy and reducing shock, thereby improving the stability of the device. The crossbeam 4 is fixed to the connecting block 501 by plugging. Since four groups of first fixing plates 503 are symmetrically arranged on the left and right sides of the limiting groove 502, and the fixing plates 503 are fixed to the connecting block 501 by bolts, it is possible to avoid drilling holes on the sides of the vertical steel column 1, thereby further improving the supporting performance of the vertical steel column 1. The lower end surface of the connecting block 501 is bolted with a second fixing plate 504 for supporting the connecting block 501, thereby improving the stability of the connecting assembly 2. The first fixing plate 503 and the second fixing plate 504 are both L-shaped steel plates, and the upper and lower sides of the first fixing plate 503 are fitted with the inner side of the crossbeam 4, which can strengthen the connection strength between the crossbeam 4 and the vertical steel column 1, thereby improving the bearing capacity of the crossbeam, causing the crossbeam to collapse due to overload.

[0023] In summary, when this type of steel column connection structure is used, first, by inserting the fixing ring 501 on the outside of the vertical steel column 1, and installing both ends of the buffer 302 on the hinge seat 304, then inserting the connecting block 501 on the top of the vertical steel column 1, and installing the second fixing plate 504 under the connecting block 1 by bolts, and then inserting the crossbeam 4 into the limiting groove 502, at this time, the outside of the crossbeam 4 is in contact with the damping pad 521, and the first fixing plate 521 is placed on the concave parts on both sides of the crossbeam 4. The first fixing plate 503 is then installed on the side of the connecting block 501 by bolts, thereby completing the fixation of the cross beam 4. When the vertical steel column 1 is pulled by an external force, it can drive the internal piston 322 to compress the supporting spring 303, and squeeze the rubber block 321 through the supporting spring 303, so that the rubber block 321 deforms, generates heat through friction and absorbs shock energy, and the upper cross beam 4 and the connecting block 501 squeeze the nylon pad 521, and plastic deformation is beneficial to improve the shock resistance.
