[0002] Steel structure diagonal braces are important connecting components in steel structure buildings. They form a triangular distribution connection with the steel frame and increase the lateral load strength of the steel frame. This not only improves the supporting force of the entire steel structure building, but also increases the connection stability between steel structures, making the steel structure building have a stronger anti-topple effect.

[0003] The diagonal brace is installed on the inner side of the angle of the large-span, high-load steel frame.

[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 diagonal brace steel structure connection assembly is used for adjustable support of the angle of the steel structure, such as Figure 1 As shown, it is mainly composed of a diagonal bracing beam 1, a T-shaped seat 2, a positioning component, and a pushing component;

[0030] like Figure 2 , Figure 3 , Figure 5As shown, fork grooves 15 are provided at both ends of the diagonal bracing beam 1, and strip nail holes 13 are provided at the ends of the diagonal bracing beam 1 on both sides of the fork grooves 15, the strip nail holes 13 are distributed along the diagonal bracing beam 1 in a straight line, and the width of the strip nail holes 13 is uniform, and slide grooves 12 are symmetrically provided on both sides of the fork grooves 15;

[0031] like Figure 4 , Figure 5 , Figure 6 As shown, the T-shaped seat 2 is composed of a plane plate and a branch end, the branch end is vertically welded and fixed on the surface of the plane plate to form a T-shaped distribution, and the extended end of the branch end is semicircular, the surface of the branch end has a through hole, and the thickness of the branch end is the same as the width of the fork groove 15;

[0032] like Figure 2 As shown, the pushing assembly includes a gusset plate 31, which is located at the middle part of the diagonal bracing beam 1, and two movable arms 3 are symmetrically rotated and connected at both ends of the gusset plate 31. The two movable arms 3 extend to both ends of the diagonal bracing beam 1 in an eight-shaped shape, and the gusset plate 31 and the diagonal bracing beam 1 are connected through a fastening bolt 32;

[0033] like Figure 3 , Figure 4 As shown, the positioning assembly includes a slide 4, which is adapted to be arranged in the fork groove 15, and sliders 44 are symmetrically fixed on both sides of the slide 4, and the slide 4 is slidably connected to the slide groove 12 through the sliders 44;

[0034] The adjustment and installation of the diagonal bracing beam 1 are as follows:

[0035] The two T-shaped seats 2 are fixed at the set position of the steel structure by welding or bolting to ensure the accuracy of the connection position. The fork grooves 15 at both ends of the diagonal bracing beam 1 are clamped at the branch ends of the T-shaped seat 2, and the strip nail hole 13 is aligned with the through hole at the branch end of the T-shaped seat 2. Since the strip nail hole 13 is long, the corresponding position of the strip nail hole 13 and the through hole can be adjusted according to the distribution of the two T-shaped seats 2. The diagonal bracing beam 1 and the T-shaped seat 2 are fixedly connected by using fixing bolts 21 to penetrate the strip nail hole 13 and the through hole. At this time, the fixing bolts 21 are not fully tightened;

[0036] The end of the movable arm 3 is connected to the positioning assembly. By tightening the fastening bolts 32, the buckle plate 31 is brought close to the diagonal bracing beam 1, driving the two movable arms 3 to change their angles, so that the ends of the movable arms 3 push the sliding seat 4 to squeeze and contact the support ends of the T-shaped seats 2, so that the diagonal bracing beam 1 forms a fixed support between the two T-shaped seats 2, avoiding the diagonal bracing beam 1 from moving between the two T-shaped seats 2, and then fully tightening the fixing bolts 21 to achieve a stable and fixed connection between the diagonal bracing beam 1 and the T-shaped seat 2.

[0037] like Figure 4 , Figure 5 , Figure 6As shown, the edge of the support end of the T-shaped seat 2 is a semicircular tooth plate, and the end of the slide seat 4 is integrally fixed with a tooth block 41. When the movable arm 3 pushes the slide seat 4 to be squeezed toward the support end of the T-shaped seat 2, the tooth block 41 is adapted to be engaged with the tooth plate to lock the connection angle between the diagonal bracing beam 1 and the T-shaped seat 2, thereby further improving the connection stability between the diagonal bracing beam 1 and the T-shaped seat 2.

[0038] like Figure 5 , Figure 6 , Figure 8 As shown, the slide 4 is a hollow structure that is laterally penetrated, and two wing arms 45 are symmetrically and elastically rotatably installed in the slide 4 by using a torsion spring. The two wing arms 45 are distributed in an eight-shaped shape and are opposite to the slide grooves 12 on both sides. The wing arms 45 have a protruding tooth surface 46, and the edge of the slide groove 12 has a rack 14;

[0039] like Figure 7 As shown, the movable arm 3 is connected to the slide 4 through an extrusion member, and the extrusion member includes a feeler rod 43 and a U-shaped seat 42. The feeler rod 43 is arranged at the angle between the two wing arms 45. The upper and lower surfaces of the slide 4 are correspondingly provided with a limit groove 47. The upper and lower ends of the feeler rod 43 vertically pass through the limit groove 47. The U-shaped seat 42 is slidably clamped on the upper and lower surfaces of the slide 4. The upper and lower ends of the feeler rod 43 are fixedly connected to the U-shaped seat 42. The end of the movable arm 3 is rotatably connected to the U-shaped seat 42.

[0040] Tightening the fastening bolts 32 pushes the two movable arms 3 to expand along the length direction of the diagonal bracing beam 1, so that the ends of the movable arms 3 push the U-shaped seat 42 and the slide 4 to move in the direction of the T-shaped seat 2. When the tooth block 41 contacts and engages with the support end of the T-shaped seat 2, the slide 4 stops moving, and the movable arm 3 pushes the U-shaped seat 42 and the feeler rod 43 to continue moving. At this time, the moving feeler rod 43 contacts the angle between the two wing arms 45, causing the two wing arms 45 to expand, and the tooth surface 46 laterally engages with the rack 14, so that a stable connection relationship is formed between the slide 4, the diagonal bracing beam 1, and the T-shaped seat 2.

[0041] like Figure 5 , Figure 6 As shown, two angle plates 5 are symmetrically and elastically installed on both sides of the diagonal bracing beam 1 through torsion springs, the wing arms 45 pass through the slide grooves 12 to abut against the inner side of the rear portion of the angle plates 5, and a slot 51 is provided at the front end of the angle plates 5. When the two wing arms 45 expand, the outer ends of the wing arms 45 abut against the rear portion of the angle plates 5, so that the front ends of the two angle plates 5 rotate and fit toward the side of the diagonal bracing beam 1, and the slot 51 is clamped at the end of the fixing bolt 21 and the outer side of the nut to prevent the fixing bolt 21 from loosening, thereby keeping the diagonal bracing beam 1 and the T-shaped seat 2 stably connected.

[0042] The wing arm 45 is curved, and one end of the wing arm 45 contacts the angle plate 5 in an arc shape. The feeler rod 43 is cylindrical, and the feeler rod 43 contacts the wing arm 45 in an arc shape, reducing the friction force and forming a stable support between the feeler rod 43, the wing arm 45 and the angle plate 5.

[0043] like Figure 1 , Figure 2 As shown, an arc-shaped fixing plate 11 protruding outward in an arc shape is fixed on the surface of the diagonal bracing beam 1, and the arc-shaped fixing plate 11 is located on the symmetrical side of the buckle plate 31. The diagonal bracing beam 1 and the arc-shaped fixing plate 11 form a balanced support on the symmetrical side of the diagonal bracing beam 1 to prevent the diagonal bracing beam 1 from deforming and bending due to force.

[0044] 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.
