[0030] A steel structure connection structure and a steel structure building, such as Figure 1 and Figure 2 As shown, including:

[0031] The connecting seat 10 is a block structure for bearing weight;

[0032] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in the figure, the limiting component is arranged on the side wall of the connecting seat 10 for connecting and limiting the connecting seat 10 and the channel steel. The limiting component includes a first locking plate 11, a second locking plate 12 and an installation channel 22. The first locking plate 11 and the second locking plate 12 are arranged on the same side wall surface of the connecting seat 10. Both the first locking plate 11 and the second locking plate 12 are slidably connected to the connecting seat 10. The same side wall surfaces of the first locking plate 11 and the second locking plate 12 are both provided with the same installation channel 22. The channel steel is inserted into the installation channel 22. The first locking plate 11 and the second locking plate 12 are locked and closed by fasteners. Both the first locking plate 11 and the second locking plate 12 are block-shaped structures. The installation channel 22 is opened on the wall surface away from the connecting seat 10. The installation channel 22 forms a groove with a concave cross-section. The two installation channels 22 on the wall surfaces of the first locking plate 11 and the second locking plate 12 together form an I-shaped notch adapted to the channel steel. In this solution, by setting the slidable first locking plate 11 and second locking plate 12, when installing the channel steel, pull the first locking plate 11 and the second locking plate 12 to separate from each other, and then the installation channel 22 is in an open state. Put the channel steel (I-beam) into one of the installation channels 22, and use bolts and nuts to lock and fasten the first locking plate 11 and the second locking plate 12. Then the channel steel is limited within the two installation channels 22. The channel steel is limited by the closed first locking plate 11 and second locking plate 12. Compared with the prior art in which the channel steel is inserted into the installation channel 22 along the radial direction of the channel steel, in this solution, the open installation channel 22 is obviously more convenient for the channel steel to enter, has the characteristic of convenient installation, and reduces the interference caused by the shaking of the channel steel during the hoisting process to the installation.

[0033] As Figure 3 shown, the limiting component further includes bolt holes 23. Bolt holes 23 are penetrated and opened on the wall surfaces of the first locking plate 11 and the second locking plate 12. Installation holes are horizontally opened on the abdominal wall of the channel steel opposite to the bolt holes 23. The fasteners include bolts and nuts. The bolts pass through the bolt holes 23 and the installation holes, and the nuts are threadedly connected to the bolts and press and fix the first locking plate 11 and the second locking plate 12. By setting the bolt holes 23, after the channel steel is embedded in one of the installation channels 22, insert the bolt into the bolt hole 23 and push it horizontally. The bolt enters the installation hole from the bolt hole 23 of the first locking plate 11 and passes out from the bolt hole 23 of the second locking plate 12. Use the nut to fasten the bolt. Then the first locking plate 11 and the second locking plate 12 approach each other. The channel steel can be calibrated with the relative movement of the first locking plate 11 and the second locking plate 12 and inserted into the installation channel 22, having the effect of locking the channel steel and the first locking plate 11 and the second locking plate 12.

[0034] As Figure 3 and Figure 4As shown, the limit component further includes a anti - detachment groove 20 and a convex block 21. The anti - detachment groove 20 is formed on the wall surface of the first locking plate 11, and the convex block 21 is fixedly connected to the second locking plate 12. When the first locking plate 11 and the second locking plate 12 are in contact, the convex block 21 is inserted into the anti - detachment groove 20. As a supplement to the above solution, by inserting the convex block 21 into the anti - detachment groove 20, when the first locking plate 11 and the second locking plate 12 are closed, the convex block 21 can provide a certain shear resistance for the first locking plate 11 and the second locking plate 12, enhance the strength after the first locking plate 11 and the second locking plate 12 are in contact, and thus ensure the load - bearing effect.

[0035] As Figure 2 and Figure 3 shown, the limit component further includes a slot 13 and a plug 14. The same plug 14 is fixedly installed on the wall surfaces of the first locking plate 11 and the second locking plate 12, and the same slot 13 is formed around the connecting seat 10. The plug 14 can be inserted into the slot 13 and slide within the slot 13. The slot 13 forms a notch with a dovetail - shaped cross - section. The plug 14 and the slot 13 are used in cooperation with each other. The slot 13 is as long as the connecting seat 10. By pushing the plug 14 into the slot 13, the first locking plate 11 and the second locking plate 12 can be installed on one side of the connecting seat 10. The first locking plate 11 and the second locking plate 12 can be installed around the connecting seat 10 for multi - directional connection. The plug 14 can slide within the slot 13. First, it can adjust the distance between the first locking plate 11 and the second locking plate 12, thus facilitating the installation of the channel steel. Secondly, the plug 14 can be detached from the slot 13, thus realizing the disassembly and assembly of the first locking plate 11 and the second locking plate 12. It can adjust the size of the installation channel 22 formed on the wall surfaces of the first locking plate 11 and the second locking plate 12 according to requirements. By replacing the first locking plate 11 and the second locking plate 12 with different - sized installation channels 22, the connection and installation of channel steels of multiple specifications can be realized, which has better installation adaptability and use flexibility.

[0036] As Figure 6As shown in the figure, a steel structure building includes columns. Multiple columns together form a support frame. All the above-mentioned steel structure connection structures are provided on the columns. The connecting seat 10 is detachably installed on the column. The channel steel tightens two adjacent columns to form an integral body. A limiting plate is fixedly installed on the column. A positioning plate is provided on the limiting plate. The positioning plate is inserted into the column. The positioning plate and the limiting plate are locked by bolts. The connecting seat 10 is arranged between the positioning plate and the limiting plate. Specifically, the positioning plate and the limiting plate can be rectangular plates or circular plates. Through grooves adapted to the columns are opened at the central positions of the positioning plate and the connecting seat 10 to facilitate the installation of the connecting seat 10 and the positioning plate. Round holes can be opened at the four corners of the connecting seat 10, the positioning plate and the limiting plate for installing bolts. The connecting seat 10 is limited by the positioning plate and the limiting plate to realize the installation and fixation of the connecting seat 10. The channel steel connects multiple connecting seats 10 to form an integral body and constitutes a support frame. A thermal insulation board is installed on the top of the support frame to form a roof, and thermal insulation boards are installed between the columns to form walls, which will not be elaborated here.

[0037] The working principle of the present utility model: Push the insertion block 14 into the insertion slot 13, and the first locking plate 11 and the second locking plate 12 can be installed on one side of the connecting seat 10. The first locking plate 11 and the second locking plate 12 can be installed around the connecting seat 10 for multi-directional connection. The insertion block 14 slides in the insertion slot 13. Firstly, the distance between the first locking plate 11 and the second locking plate 12 can be adjusted, which is convenient for the installation of the channel steel. Secondly, the insertion block 14 can be separated from the insertion slot 13, so as to realize the disassembly and assembly of the first locking plate 11 and the second locking plate 12. The size of the installation channel 22 opened on the wall surfaces of the first locking plate 11 and the second locking plate 12 can be adjusted according to requirements. The connection and installation of channel steels of multiple specifications are realized by replacing the first locking plate 11 and the second locking plate 12 with different sizes of installation channels 22.

[0038] When installing the channel steel, pull the first locking plate 11 and the second locking plate 12 to separate from each other, so that the installation channel 22 is in an open state. Put the channel steel (I-beam) into one of the installation channels 22, and use bolts and nuts to lock the first locking plate 11 and the second locking plate 12. Then the channel steel is limited in the two installation channels 22. The channel steel is limited by the closed first locking plate 11 and the second locking plate 12. When the first locking plate 11 and the second locking plate 12 are closed, the convex block 21 can provide a certain shear resistance for the first locking plate 11 and the second locking plate 12, enhancing the strength after the first locking plate 11 and the second locking plate 12 are in contact.
