Technical Field

[0001] The invention relates to the field of supports, in particular to a tensile shear resistant cylindrical support with a certain beam-falling prevention function. Background Art

[0002] In bridges and other civil engineering projects, the superstructure and the substructure transfer loads, displacements and rotations through supports. Cylindrical steel supports are one of the most commonly used supports on the market because of their simple structure, good force performance, material saving, ability to meet bridge deformation requirements and good stability during bridge erection.

[0003] When natural disasters such as pier settlement and earthquakes occur, the bearings may experience large displacements and rotations, which in turn affect the stability and safety of the bridge structure. Especially for bridges in special locations, such as continuous beam side piers, cable-stayed bridge side piers, and large suspension bridges, wind loads may cause the upper and lower bearings to become vacant, leading to the risk of falling beams. Summary of the invention

[0004] The technical problem to be solved by the present invention is that bridges in some special locations, such as continuous beam side piers, cable-stayed bridge side piers, and large suspension bridges, may be emptied above and below the supports under the action of wind loads, thereby leading to the risk of falling beams.

[0005] The technical solution adopted by the present invention to solve its technical problem is: a tensile-shear cylindrical support with a certain anti-falling beam function, including an upper support plate, an upper swing assembly is provided at the lower end of the upper support plate, a lower support assembly is provided at the lower end of the upper swing assembly, and tensile-shear assemblies are provided on both sides of the upper support plate, and the tensile-shear assemblies vertically limit and fix the upper support plate and the lower support assembly.

[0006] The effect achieved by the above components is: when in use, an upper swing assembly will be set between the upper support plate and the lower support assembly, and a tensile shear assembly will be set between the upper support plate and the lower support assembly to perform vertical limiting fixation to prevent the upper and lower supports from being empty, thereby causing the risk of falling beams.

[0007] Preferably, baffles are provided around the upper support plate, and the size of the baffles is matched with the size of the upper swing block.

[0008] The effect achieved by the above components is: by using the stopper on the upper support plate, the relative displacement between the upper support plate and the upper swing block is limited.

[0009] Preferably, the upper swing assembly includes an upper swing block, which is arranged at the lower end of the upper support plate, and the lower end of the upper swing block is fixedly connected to a curved stainless steel plate, and side slide plates are provided on both sides of the curved stainless steel plate.

[0010] Preferably, the lower support assembly comprises a lower support plate, the upper end of the lower support plate is provided with a curved slide plate, and the side surface of the lower support plate is provided with a side stainless steel plate.

[0011] Preferably, grooves are provided on both sides of the upper support plate, the arc of the bottom surface of the groove of the upper support plate is concentric with the arc of the cylindrical surface of the upper swing block, and a first through hole is provided at the arc of the bottom surface of the groove of the upper support plate.

[0012] Preferably, the locking threaded holes are provided on both sides of the lower support plate, and the sizes of the locking threaded holes on both sides of the lower support plate are adapted to the size of the first through hole at the arc of the bottom surface of the groove of the upper support plate.

[0013] Preferably, the tensile shear resistance assembly includes a sliding block, which is arranged inside the groove of the upper support plate, and a second through hole is opened inside the sliding block. A gull locking bolt is inserted into the second through hole on one side of the sliding block, and the size of the locking bolt is compatible with the size of the first through hole at the arc of the bottom surface of the groove of the upper support plate, the second through hole inside the sliding block, and the locking threaded holes on both sides of the lower support plate.

[0014] The effect achieved by the above-mentioned components is: the locking bolt passes through the first through hole provided on the bottom surface of the groove of the upper support plate and the second through hole provided on the sliding block, and then is screwed into the locking threaded holes provided on both sides of the lower support plate, and a locking nut is set on the locking bolt to fix it, and then the reinforcement of the upper support plate and the lower support plate is completed. By using the tensile shear assembly, when the support is subjected to vertical tension, the upper support plate first moves upward until the bottom surface of the locking bolt contacts the top surface of the sliding block, and then the locking bolt will limit the support from continuing to have vertical displacement, avoiding the support from being emptied up and down, thereby causing the risk of falling beams, thereby improving the use effect of the tensile shear cylindrical support.

[0015] In summary, the beneficial effects of the present invention are:

[0016] By using the tensile shear assembly, when the support is subjected to vertical tension, the upper support plate will first move upward until the bottom surface of the locking bolt contacts the top surface of the sliding block, and then the locking bolt will limit the support from further vertical displacement, preventing the support from being empty above and below, which would lead to the risk of falling beams, thereby improving the use effect of the tensile shear cylindrical support.

[0024] Figures 1 to 3 The tensile shear cylindrical support with a certain anti-falling beam function shown in the figure comprises an upper support plate 1, an upper swing assembly 2 is provided at the lower end of the upper support plate 1, a lower support assembly 3 is provided at the lower end of the upper swing assembly 2, and tensile shear assemblies 4 are provided on both sides of the upper support plate 1, and the tensile shear assemblies 4 are used to vertically limit and fix the upper support plate 1 and the lower support assembly 3. When in use, the upper swing assembly 2 is provided between the upper support plate 1 and the lower support assembly 3, and the tensile shear assemblies 4 are provided between the upper support plate 1 and the lower support assembly 3 to perform vertical limit and fixation to prevent the upper and lower supports from being emptied, thereby causing the risk of falling beams.

[0025] Figures 1 to 3The upper support plate 1 shown is provided with baffles around it, and the size of the baffles is adapted to the size of the upper swing block 21. By using the baffles on the upper support plate 1, the relative displacement between the upper support plate 1 and the upper swing block 21 is limited. The upper swing assembly 2 includes an upper swing block 21, which is arranged at the lower end of the upper support plate 1, and a curved stainless steel plate 22 is fixedly connected to the lower end of the upper swing block 21, and side slide plates 23 are arranged on both sides of the curved stainless steel plate 22. The lower support assembly 3 includes a lower support plate 31, and a curved slide plate 32 is arranged at the upper end of the lower support plate 31, and a side stainless steel plate 33 is arranged on the side of the lower support plate 31. The curved stainless steel plate 22 on the bottom surface of the upper swing block 21 and the curved slide plate 32 embedded on the top surface of the lower support plate 31 form a curved sliding friction, and in the transverse direction, the side stainless steel plates 33 on both sides of the inner cavity of the lower support plate 31 and the side slide plates 23 embedded on both sides of the upper swing assembly 2 form a side rotation friction.

[0026] Figures 1 to 3 The lower support plate 31 shown is provided with locking threaded holes on both sides, and the size of the locking threaded holes on both sides of the lower support plate 31 is adapted to the size of the first through hole at the arc of the bottom surface of the groove of the upper support plate 1.

[0027] Figures 1 to 3 The anti-tensile shear assembly 4 shown includes a sliding block 41, which is arranged inside the groove of the upper support plate 1. A second through hole is opened inside the sliding block 41. A gull locking bolt 42 is inserted into the second through hole on one side of the sliding block 41. The size of the locking bolt 42 is compatible with the size of the first through hole at the arc of the bottom surface of the groove of the upper support plate 1, the second through hole inside the sliding block 41, and the locking threaded holes on both sides of the lower support plate 31. The locking bolt 42 passes through the first through hole provided on the bottom surface of the groove of the upper support plate 1 and the second through hole provided on the sliding block 41, and then is screwed into the locking threaded holes provided on both sides of the lower support plate 31, and a locking nut 43 is set on the locking bolt 42 to fix it, and then the reinforcement of the upper support plate 1 and the lower support plate 31 is completed. By using the tensile shear component 4, when the support is subjected to vertical tension, the upper support plate 1 first moves upward until the bottom surface of the locking bolt 42 contacts the top surface of the sliding block 41, and then the locking bolt 42 will limit the support from continuing to have vertical displacement, avoiding the support from being emptied up and down, thereby causing the risk of falling beams, thereby improving the use effect of the tensile shear cylindrical support.

[0028] Figures 1 to 3 After the support shown in the figure is displaced, the upper swing assembly 2 and the sliding block 41 are not concentric, and the sliding block 41 changes in height when rotating. After the support is displaced to the left and rotates clockwise, the sliding block 41 becomes higher, and after the support is displaced to the left and rotates counterclockwise, the sliding block 41 becomes lower. Therefore, a certain gap needs to be reserved between the bottom surface of the support locking bolt 42 and the top surface of the sliding block 41, and then the locking nut 43 is fixed.

[0029] Working principle: When in use, an upper swing assembly 2 will be arranged between the upper support plate 1 and the lower support assembly 3. The curved stainless steel plate 22 on the bottom surface of the upper swing block 21 and the curved skateboard 32 inlaid on the top surface of the lower support plate 31 form a curved sliding friction. In the transverse direction, the side stainless steel plates 33 on both sides of the inner cavity of the lower support plate 31 and the side skateboards 23 inlaid on both sides of the upper swing assembly 2 form a side rotation friction, and a tensile shear assembly 4 is arranged between the upper support plate 1 and the lower support assembly 3 to perform vertical limiting fixation to avoid the upper and lower parts of the support being emptied, thereby causing the risk of falling beams. The locking bolt 42 passes through the first through hole provided on the bottom surface of the groove of the upper support plate 1 and the second through hole provided on the sliding block 41, and then is screwed into the locking threaded holes provided on both sides of the lower support plate 31, and a locking nut 43 is set on the locking bolt 42 to fix it, and then the reinforcement of the upper support plate 1 and the lower support plate 31 is completed. By using the tensile shear component 4, when the support is subjected to vertical tension, the upper support plate 1 first moves upward until the bottom surface of the locking bolt 42 contacts the top surface of the sliding block 41, and then the locking bolt 42 will limit the support from continuing to have vertical displacement, avoiding the support from being emptied up and down, thereby causing the risk of falling beams, thereby improving the use effect of the tensile shear cylindrical support.
