[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts belong to the scope protected by the present utility model.
[0025] See Figures 1-4 As shown, the present utility model provides a steel structure sliding support connection structure, including two plate bodies 1, the two plate bodies 1 are arranged one above the other and distributed in a cross shape. A middle support 2 is provided between the two plate bodies 1. A spherical seat 4 is provided on the upper surface of the middle support 2. And sliding connecting pieces for enabling the middle support 2 to move along its respective length direction are provided on the opposite surfaces of the two plate bodies 1. Padding plates 7 for enabling the middle support 2 to automatically return to the middle are fixedly connected to the opposite surfaces of the two plate bodies 1. Fixed baffles 13 and movable baffles 12 are provided on the opposite surfaces of the two plate bodies 1. The fixed baffle 13 is fixedly connected to the surface of the plate body 1, and the movable baffle 12 is detachably connected to the surface of the plate body 1 through a bolt connecting piece 3. And the fixed baffle 13 and the movable baffle 12 are respectively located at both ends of the padding plate 7. The two plate bodies 1 designed in a cross shape can effectively disperse and bear the gravity in the vertical direction, the tensile force in the horizontal direction, and even the shear force at any angle.
[0026] As an alternative embodiment, the sliding connector includes L-shaped sliding rails 5 fixedly connected to both sides of the surface of the plate body 1. Both ends of the middle support 2 are fixedly connected with sliding strips 6 slidably connected to the L-shaped sliding rails 5, enabling the middle support 2 to be slidably connected in the activity cavity formed between the two L-shaped sliding rails 5 through the sliding strips 6, so that the middle support 2 can move on the surface of the plate body 1.
[0027] Referring to Figure 2 As shown, the backing plate 7 consists of three sections along its length direction, including a horizontal section 71 in the middle and inclined sections 72 at both ends of the horizontal section 71. The lower ends of the two inclined sections 72 are connected to the horizontal section 71. The inclination angle of the inclined section 72 is 2 - 5 degrees, and the backing plate 7 is made of stainless steel. When subjected to deformation and displacement, the surface of the middle support 2 frictionally moves on the surface of the backing plate 7, causing the end face of the middle support 2 to move from the horizontal section 71 to the inclined section 72. At this time, under the wedge-shaped fit, the distance between the sliding strip 6 and the L-shaped sliding rail 5 gradually decreases and frictions, slowing down the displacement of the middle support 2. When not under force, under the action of the self-weight of the steel structure pressing down, the middle support 2 automatically falls along the inclined section 72 to the horizontal section 71 under gravity, realizing automatic reset. The inclined section 72 has the best reset effect under the design of 2 - 5 degrees. The stainless steel backing plate 7 can maintain good working performance under different environmental conditions, effectively coping with temperature changes, chemical corrosion, or mechanical stress, ensuring the stability and reliability of the support.
[0028] Referring to Figure 3 As shown, a first sliding backing plate 8 is fixedly connected to the lower end face of the middle support 2, and a second sliding backing plate 11 is fixedly connected to the upper surface of the spherical seat 4. The first sliding backing plate 8 and the second sliding backing plate 11 are respectively abutted against the surfaces of the two backing plates 7, and both the first sliding backing plate 8 and the second sliding backing plate 11 are made of polytetrafluoroethylene. The polytetrafluoroethylene material has characteristics such as extremely low friction coefficient, self-lubricating and maintenance-free, strong adaptability, high friction resistance and long life, and high load-bearing.
[0029] As an alternative embodiment, an arc-shaped groove 9 adapted to the spherical seat 4 is formed on the upper surface of the middle support 2, and an arc-shaped backing plate 10 abutted against the arc-shaped groove 9 is fixedly connected to the bottom surface of the spherical seat 4. The arc-shaped backing plate 10 is made of polytetrafluoroethylene. Through the arc-shaped design, the gravity received in the vertical direction of the structure can be effectively eliminated.
[0030] Referring to Figure 2As shown in the figure, the bolt connection member 3 includes a bolt 3a rotatably connected to the middle of the movable baffle 12. Bolt holes 3b threadedly connected to the bolt 3a are formed on the surface of the plate body 1. Convex blocks 3c are fixedly connected to both sides of the bottom surface of the movable baffle 12. Two insertion holes 3d into which the convex blocks 3c are inserted are formed on the surface of the plate body 1. When the movable baffle 12 is removed, the slide bar 6 on the middle support 2 can be inserted between the two L-shaped slide rails 5 from one side of the movable baffle 12. Then, the bolt 3a is inserted into the bolt hole 3b and rotated to make the movable baffle 12 gradually close to the surface of the plate body 1. At this time, the two convex blocks 3c are controlled to be inserted into the two insertion holes 3d to complete the position fixation of the movable baffle 12. After the position of the movable baffle 12 is fixed, the slide bar 6 cannot be removed from the gap between the L-shaped slide rail 5 and the movable baffle 12 (nor can it be removed from the gap between the fixed baffle 13). The fixed baffle 13 and the movable baffle 12 can limit the movement of the middle support 2 to prevent the middle support 2 from separating from the plate body 1.
[0031] Specifically, welding grooves 14 are formed around the opposite surfaces of the two plate bodies 1 to facilitate welding and fixing the plate bodies 1 to the steel structure.
[0032] With the above structure, the middle support 2 is slidably connected to the two plate bodies 1 through two sliding connection members respectively. At this time, the spherical seat 4 is located between the middle support 2 and the upper plate body 1. Then, the fixed baffle 13 is fixed to the surface of the plate body 1 through the bolt connection member 3 to prevent the middle support 2 from separating from the surface of the plate body 1. Then, the two plate bodies 1 are respectively welded and supported to the upper and lower steel structures. After displacement and deformation occur, the spherical seat 4 and the middle support 2 are respectively driven to contact and rub with the two cushion blocks 7. Under the action of gravity extrusion, the spherical seat 4 and the middle support 2 are respectively moved to the middle parts of the upper and lower cushion blocks 7 to achieve automatic reset.
[0033] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
