Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to a steel structure. Background Technology

[0002] Steel structures are structures primarily composed of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, which are typically connected by welds, bolts, or rivets. Due to their light weight and ease of construction, steel structures are widely used in large factories, stadiums, and high-rise buildings.

[0003] Currently, the connection between steel columns and steel beams is the most crucial link in the entire steel structure, determining the overall structural strength. The existing method of connecting steel columns and steel beams involves placing one end of the steel beam against one side of the steel column, and then passing bolts through the end face of the steel beam and the side face of the steel column to fix the steel beam and steel column together. For this purpose, it is necessary to pre-drill bolt holes in the steel beam and fix it through the threaded connection between the bolts and the bolt holes. However, because the steel beam is relatively heavy, the lack of pre-fixation before connecting it to the steel column makes it difficult to align the bolts with the bolt holes, making the operation of connecting the steel column and steel beam cumbersome, time-consuming, and labor-intensive.

[0006] As a further feature of this utility model, both ends of the positioning insert are threaded with several fastening bolts, and both the mounting base and the steel beam have several threaded holes that match the fastening bolts.

[0007] As a further feature of this utility model, stop plates are provided on both sides of the mounting base. When the positioning strip abuts against the stop plates, the fastening bolts and threaded holes are aligned in sequence.

[0008] As a further feature of this utility model, the first connecting sleeve is provided with a plurality of pins, and the second connecting sleeve is provided with a plurality of insertion holes for inserting the pins.

[0009] As a further feature of this invention, an elastic gasket is provided at the bottom of the positioning insert, and the elastic gasket is made of rubber material.

[0010] As a further feature of this invention, a cross groove is provided on the top of the fastening bolt.

[0011] As a further feature of this invention, both the mounting base and the steel beam have an I-shaped cross-section.

[0012] As a further feature of this invention, the steel column, mounting base, and steel beam are all made of stainless steel.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] When installing a steel beam onto a steel column, this utility model allows the steel beam to be aligned and fitted with the mounting base, so that the first connecting sleeve and the second connecting sleeve are aligned and connected to each other. Then, a positioning insert is inserted between the first connecting sleeve and the second connecting sleeve, thereby connecting the first connecting sleeve and the second connecting sleeve in series and achieving pre-fixation of the steel beam on the steel column, which facilitates subsequent threaded connection. The operation is relatively convenient, saving time and effort. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 As shown, a steel structure includes a steel column 1 and a steel beam 2. A mounting base 3 is provided on the side wall of the steel column 1. Both the mounting base 3 and the steel beam 2 have I-shaped cross-sections, which reduces weight while ensuring strength. The steel column 1, mounting base 3, and steel beam 2 are all made of stainless steel, which has high strength and corrosion resistance, thus giving the steel structure good durability. The steel beam 2 is detachably connected to the mounting base 3 by a fastening assembly. The fastening assembly includes a first connecting sleeve 4 and a second connecting sleeve 5 that match each other. The first connecting sleeve 4 is located on the side wall of the mounting base 3. The two connecting sleeves 5 are set on the side wall of the steel beam 2, and a positioning insert 6 is inserted between the first connecting sleeve 4 and the second connecting sleeve 5. When the steel beam 2 is installed on the steel column 1, the steel beam 2 can be aligned and fitted with the mounting base 3, so that the first connecting sleeve 4 and the second connecting sleeve 5 are aligned and connected to each other. Then, the positioning insert 6 is inserted between the first connecting sleeve 4 and the second connecting sleeve 5, thereby connecting the first connecting sleeve 4 and the second connecting sleeve 5 in series, realizing the pre-fixation of the steel beam 2 on the steel column 1, which facilitates the subsequent threaded connection. The operation is relatively convenient, saving time and effort.

[0022] Please see Figure 1-4 As shown, several fastening bolts 7 are threaded to both ends of the positioning insert 6, and several threaded holes 8 matching the fastening bolts 7 are opened on both side walls of the mounting base 3 and the steel beam 2. After the positioning insert 6 is inserted between the first connecting sleeve 4 and the second connecting sleeve 5, the fastening bolts 7 can be screwed into the threaded holes 8. Through the threaded connection between the fastening bolts 7 and the threaded holes 8, the connection between the positioning insert 6 and the steel beam 2 and the mounting base 3 can be realized, thereby fixing the steel beam 2 on the steel column 1. The connection is relatively firm and the operation is relatively convenient and simple. Stop plates 9 are provided on both side walls of the mounting base 3. When the positioning insert 6 abuts against the stop plate 9, the fastening bolt 7 and the threaded hole 8 are aligned in sequence. When the positioning insert 6 is inserted between the first connecting sleeve 4 and the second connecting sleeve 5, the positioning insert 6 can be pushed to slide until it abuts against the stop plate 9. The stop plate 9 can limit the positioning insert 6, so that the fastening bolt 7 and the threaded hole 8 are aligned in sequence. This makes it easier to screw the fastening bolt 7 into the threaded hole 8 for connection, making it easier to fix the steel beam 2 on the steel column 1. The fastening bolt 7 has a cross groove 13 on the top, which makes it easy to insert a cross screwdriver for tightening.

[0023] Please see Figure 3 , Figure 4As shown, a plurality of pins 10 are provided on the first connecting sleeve 4, and a plurality of insertion holes 11 for inserting the pins 10 are provided on the second connecting sleeve 5. When the first connecting sleeve 4 and the second connecting sleeve 5 are aligned, the pins 10 will be inserted into the insertion holes 11. The pins 10 are limited by the insertion holes 11, which can pre-position the first connecting sleeve 4 and the second connecting sleeve 5, so that the first connecting sleeve 4 and the second connecting sleeve 5 can remain in a connected state after alignment, thereby facilitating the insertion of the positioning strip 6. An elastic washer 12 is provided at the bottom of the positioning strip 6. The elastic washer 12 is made of rubber material and has good elasticity. When the fastening bolt 7 is screwed into the threaded hole 8, the fastening bolt 7 will squeeze the positioning strip 6, causing the elastic washer 12 to undergo elastic deformation, thereby applying a thrust to the fastening bolt 7 in the opposite direction, making the connection between the fastening bolt 7 and the threaded hole 8 tighter and less prone to loosening, thereby improving the connection strength between the steel column 1 and the steel beam 2.
