Description

Technical Field

[0001] The invention relates to the field of steel structure connectors, in particular to a steel structure node connection component. Background Art

[0002] H-shaped steel has excellent structural strength and is widely used in building steel structures. H-shaped steel is composed of two parallel flange plates and a vertically connected web. H-shaped steel is mostly used as column beams and frame beams in steel structures, resulting in a large number of vertical H-shaped steel beam nodes in steel structures.

[0003] The vertical nodes of H-shaped steel beams are generally connected in the following ways:

[0004] Method 1: Use welded plates as the connecting parts of the transverse steel beams, and fix the transverse steel beams with bolts;

[0005] Method 2: Fit the right-angle piece between the H-shaped horizontal steel beam and the H-shaped column beam, and then fix the H-shaped horizontal steel beam, the H-shaped column beam and the right-angle piece with bolts;

[0006] Both of the above connection methods require more bolts to lock the nodes to ensure that the bolts at the nodes will not loosen due to vibration or other reasons. More bolts penetrate the surface of the H-steel, which will reduce the structural strength of the H-steel. Summary of the invention

[0007] In order to make up for the deficiencies of the prior art, the purpose of the present invention is to provide a steel structure node connection member for solving the problem of preventing bolts at vertical nodes of H-shaped steel beams from loosening and improving structural strength.

[0008] In order to solve the problems of the prior art, the technical solution of the present invention is as follows:

[0009] The steel structure node connection component includes: an H-shaped steel column and an H-shaped beam, the end of the H-shaped beam is flat against the flange plate of the H-shaped steel column, and connecting plates are symmetrically arranged on both sides of the web of the H-shaped beam. The two sides of the connecting plate are fixedly connected to the flange plate of the H-shaped steel column and the web of the H-shaped beam by tension bolts and web bolts respectively, and also includes positioning bolts, which vertically penetrate the flange plate of the H-shaped beam. The surface of the connecting plate has a nail sleeve, and the positioning bolt is adapted to penetrate the nail sleeve for locating the plane position of the connecting plate.

[0010] Preferably, the connecting plate is tilted to the right angle where the H-shaped crossbeam and the H-shaped steel column are connected, so that an isosceles right triangle area is formed between the flange plate of the H-shaped steel column, the web plate of the H-shaped crossbeam, and the connecting plate, and the two ends of the connecting plate have flat parts that are flat against the flange plate of the H-shaped steel column and the web plate of the H-shaped crossbeam.

[0011] Preferably, the nail sleeve is located on the outer side of the connecting plate, and the positioning bolt vertically passes through the nail sleeve from the outer side of the connecting plate.

[0012] Preferably, the outer surface of the connecting plate is symmetrically rotated to install two V-shaped hinge plates, and the free edges of the two hinge plates are provided with slots. The positioning bolt vertically passes through the two hinge plates. The positioning bolt resists the expansion of the two hinge plates, so that the edges of the slots are aligned to squeeze the tension bolts and the nuts at the ends of the ventral bolts.

[0013] Preferably, two H-shaped beams are symmetrically arranged on the surfaces of the flange plates on both sides of the H-shaped steel column, and the tension bolts penetrate the flange plates on both sides of the H-shaped steel column and tighten and fix the connecting plates in relative positions.

[0014] Preferably, the edge of the connecting plate has a U-shaped inner buckle portion, and the inner buckle portions at the symmetrical position are offset and span the two flange plates of the H-shaped steel column and are flatly attached to the inner side of the flange plate on the symmetrical side. A positioning hole is opened at the position where the inner buckle portion is flatly attached to the flange plate of the H-shaped steel column, and the tension bolts pass through the positioning hole.

[0015] Preferably, a semicircular groove is provided at the position where the inner buckle portion spans across the two flange plates of the H-shaped steel column, and the semicircular grooves of the two aligned inner buckle portions are aligned to form a circular groove, a straight cylinder piece is arranged through the circular groove, the inner end of the straight cylinder piece abuts against the web of the H-shaped steel column, and the outer end of the straight cylinder piece has an expanded diameter portion abutting against the outer side of the circular groove, and a straight bolt passes through the straight cylinder piece and the web of the H-shaped steel column to press the inner buckle portion toward the web of the H-shaped steel column.

[0016] Preferably, a right-angled angle plate is provided below the H-shaped crossbeam, and the positioning bolts penetrate the horizontal surface of the angle plate to fix it to the flange plate of the H-shaped crossbeam, and the vertical surface of the angle plate is fixed to the flange plate of the H-shaped steel column through edge bolts.

[0017] Compared with the prior art, the advantages of the present invention are as follows:

[0018] 1. The present invention fixes the connecting plate to the H-shaped steel column and the H-shaped beam respectively through tension bolts and ventral bolts, thereby realizing a basic fixed connection between the H-shaped steel column and the H-shaped beam. The positioning bolts penetrate the nail sleeves on the surface of the connecting plate to locate the plane position of the connecting plate, effectively alleviating the connecting plate from contacting the nuts of the tension bolts and ventral bolts outward due to vibration, thereby improving the strength of the connecting plate to fit the H-shaped steel column and the H-shaped beam.

[0019] 2. The present invention squeezes the two hinge plates to expand by positioning bolts, so that the edges of the slots apply pressure to the nuts at the ends of the tension bolts and the flank bolts, respectively, to prevent the nuts of the tension bolts and the flank bolts from loosening, and further improve the connection stability between the H-shaped steel column and the H-shaped beam.

[0020] 3. When the H-shaped steel column symmetrically connects two H-shaped beams, the present invention uses an inner buckle portion integrated with the connecting plate to provide internal support for the flange plate of the H-shaped steel column, and the tension bolts penetrate the flange plates on both sides of the H-shaped steel column to effectively prevent the flange plates on both sides from expanding and deforming. Inner buckles are added to the flange plates of the H-shaped steel column to prevent the flange plates from buckling and deforming inwardly, thereby improving the deformation resistance of the flange plates on both sides of the H-shaped steel column and ensuring that they have a stable connection load strength.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] The steel structure node connection member is for the vertical node anti-loosening connection between the H-shaped beam 2 and the H-shaped steel column 1 in the steel structure building. This connection method is applicable to the vertical connection of the H-shaped steel column 1 on one side to the H-shaped beam 2, or the vertical connection of the symmetrical side of the H-shaped steel column 1 to the H-shaped beam 2;

[0030] The specific operation of connecting the H-shaped steel column 1 vertically on one side to the H-shaped beam 2 is as follows:

[0031] like Figure 1-4As shown, the H-shaped cross beam 2 is vertically attached to the surface of the flange plate of the H-shaped steel column 1, and the connecting plates 3 are symmetrically arranged at the two right-angled parts formed by the web of the H-shaped cross beam 2 and the flange plate of the H-shaped steel column 1. The connecting plates 3 are inclined so that an isosceles right triangle area is formed between the flange plate of the H-shaped steel column 1, the web of the H-shaped cross beam 2, and the connecting plates 3. Both ends of the connecting plates 3 have flat-fitting parts 34 that are flat-fitting to the flange plate of the H-shaped steel column 1 and the web of the H-shaped cross beam 2. Two groups of tension bolts 11 penetrate the flat-fitting parts 34 and the flange plate of the H-shaped steel column 1 to fix the connecting plates 3 to the H-shaped steel column 1. Two groups of belly bolts 21 penetrate the web of the H-shaped cross beam 2 and the flat-fitting parts 34 on both sides to fix the connecting plates 3 to the H-shaped cross beam 2, thereby realizing the basic fixation of the H-shaped cross beam 2 and the H-shaped steel column 1.

[0032] like Figure 4-5 As shown, the positioning bolt 5 vertically penetrates the flange plate of the H-shaped beam 2, and the outer surface of the connecting plate 3 is fixed with a nail sleeve 31. The positioning bolt 5 is adapted to penetrate the nail sleeve 31 from the outer side of the connecting plate 3, and the plane position of the connecting plate 3 is locked by the alignment of the positioning bolt 5 and the nail sleeve 31, which effectively alleviates the connecting plate 3 from contacting the nuts of the tension bolts 11 and the ventral bolts 21 outward due to vibration, avoids loosening of the tension bolts 11 and the ventral bolts 21, and improves the strength of the connecting plate 3 to fit the H-shaped steel column 1 and the H-shaped beam 2.

[0033] like Figure 4-5 As shown, two hinge plates 32 are symmetrically rotated and installed on the outer surface of the connecting plate 3. The two hinge plates 32 are distributed in a V shape, and slots 33 are provided on the free edges of the two hinge plates 32. The positioning bolts 5 vertically pass through the V-shaped parts of the two hinge plates 32. The positioning bolts 5 resist the two hinge plates 32 and have an expansion tendency, so that the free ends of the two hinge plates 32 resist the tension bolts 11 and the ventral bolts 21 respectively, and the slots 33 are aligned with the nail heads of the tension bolts 11 and the ventral bolts 21. The edges of the slots 33 squeeze the nuts at the ends of the tension bolts 11 and the ventral bolts 21 to prevent the nuts of the tension bolts 11 and the ventral bolts 21 from loosening, thereby further improving the connection stability between the H-shaped steel column 1 and the H-shaped beam 2.

[0034] like Figure 1 , Figure 3 As shown, a right-angled angle plate 4 is arranged below the H-shaped crossbeam 2, the horizontal surface of the angle plate 4 fits the flange plate at the bottom of the H-shaped crossbeam 2, the vertical surface of the angle plate 4 fits the flange plate of the H-shaped steel column 1, the positioning bolts 5 penetrate the horizontal surface of the angle plate 4 to fix it to the flange plate of the H-shaped crossbeam 2, the vertical surface of the angle plate 4 is fixed to the flange plate of the H-shaped steel column 1 by the flange bolts 12, and the angle plate 4 is added to improve the supporting effect on the connecting end of the H-shaped crossbeam 2 and increase the load strength of the H-shaped crossbeam 2.

[0035] The specific operation of vertically connecting the symmetrical side of the H-shaped steel column 1 to the H-shaped beam 2 is as follows:

[0036] like Figure 1-3 As shown, two H-shaped cross beams 2 are symmetrically attached to the flange plate surfaces on both sides of the H-shaped steel column 1, and each H-shaped cross beam 2 is fixed to the H-shaped steel column 1 by the above-mentioned locking method. Since the flange plates on both sides of the H-shaped steel column 1 bear the force, it is necessary to improve the anti-deformation effect of the flange plate of the H-shaped steel column 1;

[0037] like Figure 2 , Figure 4 As shown, the tension bolts 11 penetrate the flange plates on both sides of the H-shaped steel column 1, tighten and fix the connecting plate 3 at the opposite position, and the edge of the connecting plate 3 has a U-shaped inner buckle 6. The inner buckle 6 at the symmetrical position is staggered across the two flange plates of the H-shaped steel column 1, and then flatly attached to the inner side of the flange plate on the symmetrical side, and finally bent and attached to the web of the H-shaped steel column 1, and a positioning hole 62 is opened at the position where the inner buckle 6 is flat against the flange plate of the H-shaped steel column 1, and the tension bolts 11 penetrate the positioning hole 62;

[0038] The tension bolts 11 penetrate the flange plates on both sides of the H-shaped steel column 1, effectively preventing the flange plates on both sides from expanding and deforming. The inner buckle portion 6 attached to the flange plate of the H-shaped steel column 1 is added to prevent the flange plate from buckling inwardly, thereby improving the deformation resistance of the flange plates on both sides of the H-shaped steel column 1 and making it have a stable connection load strength.

[0039] like Figure 6 As shown, a semicircular groove 61 is provided at the position where the inner buckle part 6 spans across the two flange plates of the H-shaped steel column 1, and the semicircular grooves 61 of the two aligned inner buckle parts 6 are aligned to form a circular groove, and a straight cylinder part 7 is used to penetrate the circular groove, and the inner end of the straight cylinder part 7 abuts against the web of the H-shaped steel column 1, and the outer end of the straight cylinder part 7 has an expanded diameter part that abuts against the outer side of the circular groove, and a straight-through bolt 71 is used to penetrate the straight cylinder part 7 and the web of the H-shaped steel column 1, and the straight-through bolt 71 is tightened to press the straight cylinder part 7 toward the web of the H-shaped steel column 1 to provide force support for the middle part of the inner buckle part 6, and also to prevent the inner buckle part 6 from being deformed outward under pressure, so that the inner buckle part 6 has good supporting strength. In addition, the straight cylinder part 7 penetrates the circular groove, which has a lateral locking effect on the two inner buckle parts 6, so as to keep the two inner buckle parts 6 and the connecting plate 3 stably fitted to the H-shaped steel column 1.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
