Technical Field

[0001] The invention relates to the technical field of building structure engineering, in particular to a box-type steel column butt joint. Background Art

[0002] Traditional steel column splicing generally uses ear plates and connecting plates to temporarily fix the upper and lower columns, and then welds the joints after welding. After welding, the ear plates and connecting plates need to be removed. Therefore, in order to reduce welding points, node areas have been set up in traditional steel column splicing, and high-strength bolts are used to connect them to completely avoid on-site welding.

[0003] However, when the node area is currently connected and fixed by bolts, the force it can bear will be limited, especially when the steel columns are connected horizontally. The direction of the force, that is, the direction of gravity, on the steel columns is perpendicular to the direction of their connection. At this time, the force on the node area is entirely supported by the bolts, which will make the bolts prone to deformation and greatly limit the overall force level of the steel column connection structure.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-5 The present invention provides a technical solution: a box-type steel column butt joint, comprising a steel column 1, wherein the steel column 1 is divided into an upper steel column and a lower steel column, and further comprising:

[0031] The bearing platform 2 includes an upper bearing platform and a lower bearing platform, wherein the upper bearing platform is fixedly arranged on the upper steel column, and the lower bearing platform is fixedly arranged on the lower steel column;

[0032] The sleeve frame 3 is fixedly arranged on either the upper support platform or the lower support platform 2, and is used to cooperate with the corresponding lower support platform or the upper support platform for clamping;

[0033] The fixing unit 4 is arranged on the side of the sleeve frame 3 and the corresponding support platform 2, and is used to fix the sleeve frame 3 and the corresponding support platform 2;

[0034] The auxiliary unit 5 is arranged between the upper support platform and the lower support platform, and fixes the sleeve frame 3 and the corresponding support platform 2 from the vertical direction of the fixing unit 4;

[0035] When the steel column 1 is connected, the upper and lower units can be quickly docked through the auxiliary unit 5, and then the steel column 1 can be initially fixed by the clamping of the frame 3 and the base 2. Then, after the steel column 1 is fixed, the frame 3 and the base 2 can be fixed by the fixing unit 4 to achieve the fixation between the steel columns 1. Finally, the fixing unit 4 can be used to fix the steel column 1 in the vertical direction inside the steel column 1 through the auxiliary unit 5. Then, when the steel column 1 is fixed as a whole, the steel column 1 can be fixed inside and outside and in multiple directions, so that the steel column 1 can withstand more force after being fixed.

[0036] The fixing unit 4 includes a plurality of threaded holes 41 evenly arranged on the side of the sleeve frame 3 and the corresponding support platform 2, and the threaded holes 41 are connected after the corresponding support platform 2 is placed in the sleeve frame 3; a plurality of bolts 42 are threadedly connected to the sleeve frame 3 and its corresponding support platform 2 through the threaded holes 41 to fix them;

[0037] By designing the fixing direction and position of the bolts 42, when the steel column 1 is laid horizontally, when the steel column 1 is subjected to the force in the direction of gravity, the direction of the bolts 42 can be consistent with the direction of gravity. At this time, when the bolts 42 are subjected to force, they are subjected to force as a whole, so that the steel column 1 can withstand more force, compared with the traditional bolts 42 arranged in the connection direction of the steel column 1;

[0038] In addition, the auxiliary unit 5 comprises:

[0039] A positioning column 51 is fixedly arranged at the center of one of the platforms 2, and a positioning hole 52 is arranged on the other platform 2 for positioning with the positioning column 51, and the positioning hole 52 passes through the platform 2;

[0040] There are four plug-in tubes 53, all of which are fixedly arranged on the support platform 2 provided with the positioning holes 52. The four plug-in tubes 53 are arranged in a rectangular shape on the support platform 2, and a single plug-in tube 53 is arranged between two symmetrical sides of the support platform 2. A plug-in hole 54 used in conjunction with the plug-in tube 53 is arranged on the support platform 2 corresponding to the plug-in tube 53, and a one-way hole 55 is opened on the side of the plug-in tube 53 close to the support platform 2;

[0041] There are four sets of elastic fixing members 56, all of which are arranged on the steel column 1 with the positioning column 51;

[0042] When the steel column 1 is connected, the steel column 1 can be positioned first by the positioning column 51 and the positioning hole 52, so that the upper steel column and the lower steel column can be quickly connected when they are connected with the base 2 through the sleeve frame 3. After the connection, the plug-in pipes 53 arranged in opposite directions will be inserted into the plug-in holes 54 of the corresponding base 2 at the same time, and the positioning columns 51 and the positioning holes 52 form a cross fixed structure inside the steel column 1. When the steel column 1 is horizontally arranged and subjected to force, it can cooperate with the bolts 42 to bear the force in its vertical direction, thereby increasing the bearing capacity of the connection of the steel column 1;

[0043] Meanwhile, the elastic fixing member 56 comprises a sliding shaft 561, which is slidably arranged on the steel column 1 and penetrates the steel column 1, a spacer 562 is fixed to the outer end of the sliding shaft 561, a limiting plate 563 is fixed to the inner end, and an elastic member 564 is arranged on the sliding shaft 561 between the limiting plate 563 and the inner wall of the steel column 1, and the elastic member 564 can be set as a spring sleeved on the outside of the sliding shaft 561;

[0044] After the plug-in tube 53 is inserted into the plug-in hole 54, the sliding shaft 561 can be pulled outwards. Then, after the plug-in tube 53 is completely inserted into the steel column 1, the plug-in tube 53 is released. At this time, the end of the sliding shaft 561 will be stuck in the one-way hole 55 at the end of the plug-in tube 53, thereby fixing the plug-in tube 53, thereby assisting the fixing unit 4 to further fix the steel column 1. At the same time, when the steel column 1 is subjected to rigid force, the force can be released from the elastic member 564, thereby reducing the generation of internal stress of the steel column 1 during long-term use;

[0045] Wherein, a plurality of tripods 6 are provided between the steel column 1 and the cap 2, so as to increase the stability between the steel column 1 and the cap 2.

[0046] In addition, a pull ring 565 is fixed to the outer end of the spacer 562, so that when disassembling, it is easy to pull the sliding shaft 561 to release the fixation of the plug-in tube 53.

[0047] Finally, the inner end of the sliding shaft 561 is set to an arc shape that matches the inner wall of the plug-in tube 53, so that the sliding shaft 561 can be more closely inserted into the plug-in tube 53, so that when the steel column 1 is subjected to force and internal stress is generated, the internal stress can be easily transmitted to the elastic member 564 for release.
