DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described 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.

[0028] like Figure 1 、 Figure 2 As shown, the steel structure connection assembly with movable space is composed of a T-shaped plate, a connecting plate, an eccentric shaft handle 3, and a first elastic member 4; like Figure 3 、 Figure 5 As shown, the T-shaped plate includes a rectangular seat plate 2, and a fixed support plate 21 is vertically welded on the surface of the seat plate 2, so that the T-shaped plate is in a T shape as a whole; like Figure 3 、 Figure 4 As shown, the connecting plate includes a side plate 1, one end of the side plate 1 is bent to form a right-angle hook plate 11, the other end of the side plate 1 is fixed with a clamping seat 12, the side plate 1 and the clamping seat 12 are connected in a Z shape, so that the connection part of the side plate 1 and the clamping seat 12 forms a flat surface, and the surface of the side plate 1 is provided with an axle seat hole 13; like Figure 3 、 Figure 5 As shown, the eccentric shaft handle 3 has two parts, a positive axis and an eccentric axis. The positive axis and the eccentric axis are eccentrically fixed to maintain an eccentric distance of 2-4 cm. Two eccentric shaft handles 3 are symmetrically arranged on both sides of the support plate 21. The positive axis of the eccentric shaft handle 3 is fixedly connected to the support plate 21, and the maximum eccentric position of the eccentric shaft handle 3 is close to the seat plate 2; like Figure 6 As shown, the first elastic member 4 includes a first arc-shaped protrusion 41, and a first tail plate 42 and an arc-shaped rocker plate 43 are fixed integrally at both ends of the first arc-shaped protrusion 41. The first tail plate 42 and the arc-shaped rocker plate 43 are both tilted in the opposite direction of the protrusion of the first arc-shaped protrusion 41. The surface of the first tail plate 42 has nail holes. The assembly and connection method of the H-shaped vertical beam and the H-shaped horizontal beam is as follows: The end of the H-shaped crossbeam is set opposite to the side of the H-shaped vertical beam, and the seat plate 2 of the T-shaped plate is fixed flatly to the side of the H-shaped vertical beam with bolts, so that the support plate 21 points to the H-shaped crossbeam, and two connecting plates are symmetrically set on both sides of the end of the H-shaped crossbeam. The two connecting plates are gathered toward the middle, so that the clamping seat 12 is flat against the web of the H-shaped crossbeam and fixed with bolts. The eccentric axis of the eccentric shaft handle 3 is adapted to be inserted into the shaft seat hole 13, and the right-angle hook plate 11 extends to the inner side of the flange plate of the H-shaped vertical beam. Two first elastic members 4 are distributed up and down on the inner side of the flange plate of the H-shaped vertical beam. The first arc-shaped protrusion 41 contacts the inner side of the flange plate of the H-shaped vertical beam to fix one of the seat plates 2. The bolts penetrate the nail holes on the surface of the first tail plate 42, and the curved rocker plate 43 is tilted up to contact the upper and lower parts of the surface of the right-angle hook plate 11 respectively. The fastening bolts pull the first tail plate 42 toward the flange plate of the H-shaped vertical beam, and use the first curved protrusion 41 as a fulcrum to tilt the curved rocker plate 43, so that the curved rocker plate 43 pushes the right-angle hook plate 11 in the direction away from the flange plate of the H-shaped vertical beam. Since the farthest eccentric point of the eccentric shaft handle 3 is close to the H-shaped vertical beam, the H-shaped cross beam and the H-shaped vertical beam maintain the closest distance. The two first elastic members 4 cooperate to apply a thrust to the right-angle hook plate 11, forming a three-point support state, so that the H-shaped vertical beam and the H-cross beam maintain a fixed connection form; When the H-shaped vertical beam sinks or the entire steel structure shakes, the angle of the connection between the H-shaped vertical beam and the H-shaped cross beam changes. Since the connecting plate and the H-shaped cross beam remain fixed, the right-angle hook plate 11 will change its angle relative to the H-shaped vertical beam, causing the right-angle hook plate 11 to compress the first elastic member 4. The eccentric shaft handle 3 and the shaft seat hole 13 are adapted to rotate to adapt to the angle change between the H-shaped cross beam and the H-shaped vertical beam. The first elastic member 4 is compressed and deformed to relieve the stress caused by the angle change. In addition, the angle change of the connection node will cause the H-shaped vertical beam and the H-shaped cross beam to change. The connection spacing of the H-shaped cross beam has a tendency to expand, while the adaptation of the eccentric shaft handle 3 and the shaft seat hole 13 maintains the minimum connection spacing between the H-shaped vertical beam and the H-shaped cross beam under normal conditions. When the rotation of the eccentric shaft handle 3 and the shaft seat hole 13 overcomes the angle change, the distance between the H-shaped vertical beam and the H-shaped cross beam is increased by the change of the eccentric angle, further buffering the deformation trend of the connection node, ensuring that the H-shaped vertical beam and the H-shaped cross beam are stably connected while having space to adapt to the changes in the angle and spacing of the connection node, avoiding the fracture of the connection node between the H-shaped vertical beam and the H-shaped cross beam.

[0029] like Figure 7As shown, two second elastic members 5 are distributed above and below the end of the H-shaped crossbeam, and the second elastic member 5 includes a second arc-shaped protrusion 51. The two ends of the second arc-shaped protrusion 51 are respectively fixed to a second tail plate 52 and an arc-shaped bent plate 53. The surface of the second tail plate 52 has a nail hole. The second arc-shaped protrusion 51 abuts against the web of the H-shaped crossbeam. The arc-shaped bent plate 53 is bent until the end of the H-shaped crossbeam faces the support plate 21. One of the bolts of the fixed assembly clamp 12 passes through the nail hole on the surface of the second tail plate 52. The second tail plate 52 is tightened toward the web by the locking bolt. The arc-shaped bent plate 53 is tilted up and abuts against the support plate 21 with the second arc-shaped protrusion 51 as a fulcrum. The two arc-shaped bent plates 53 apply a thrust toward the H-shaped vertical beam to the upper and lower end surfaces of the support plate 21. The two second elastic members 5 apply elastic thrust to the support plate 21 to share the pressure on the first elastic member 4 when the angle of the connection node changes. The two first elastic members 4 and the two second elastic members 5 form four elastic support points for the H-shaped crossbeam and the H-shaped vertical beam, thereby increasing the effect of alleviating the stress generated when the angle of the connection node changes and enhancing the stability of the connection node shape under normal conditions.

[0030] The two second elastic members 5 distributed above and below the end of the H-shaped crossbeam are respectively located on both sides of the web of the H-shaped crossbeam, so that the thrust exerted by the second elastic members on the support plate 21 is more uniform.

[0031] like Figure 8 As shown, four limiting grooves 14 are evenly provided on the outer edge of the shaft seat hole 13, and a cross groove 31 is provided on the end face of the eccentric shaft handle 3. The four branch ends of the cross groove 31 are aligned with the limiting groove 14. The cross plate 6 can be adapted to be embedded in the cross groove 31, and the four branch ends of the cross plate 6 are inserted into the limiting groove 14. Bolts are used to fix the cross plate 6 and the eccentric shaft handle 3 together. The width of the limiting groove 14 is greater than the width of the branch end of the cross plate 6, so that the limiting groove 14 limits the rotation angle of the cross plate 6 to less than 10°. Since the cross plate 6, the eccentric shaft handle 3, the T-shaped plate and the H-shaped vertical beam are fixed together, the connecting plate and the H-shaped The cross beam is fixed as a whole, and the limiting groove 14 limits the angle rotation of the cross plate 6, which is actually a maximum deformation angle limit of the connection node between the H-shaped vertical beam and the H-shaped cross beam. A U-shaped rubber layer 7 is fixed in the limiting groove 14, and the end of the cross plate 6 is inserted into the rubber layer 7 with interference fit. The rubber layer 7 limits the angle of the cross plate 6, thereby improving the stability of the angle maintained at the connection node between the H-shaped vertical beam and the H-shaped cross beam. When the connection node between the H-shaped vertical beam and the H-shaped cross beam deflects, the branch end of the cross plate 6 offsets and squeezes the rubber layer 7, and the elastic deformation effect of the rubber layer 7 is used to absorb the stress caused by the angle change.

[0032] like Figure 7As shown, a shaft ring 8 is rotatably sleeved on the non-eccentric position of the eccentric shaft handle 3, that is, the positive axis position, and a stretched spring is connected between the flat surface of the connection part of the side plate 1 and the clamp seat 12 and the shaft ring 8. When the angle of the connection node between the H-shaped vertical beam and the H-shaped horizontal beam changes, the distance between the flat surface and the shaft ring 8 will increase, and the spring will be stretched. The elastic force of the spring can promote the reset of the angle of the H-shaped vertical beam and the H-shaped horizontal beam.

[0033] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
