| titleOfInvention | SUPPORT PART |
| abstract | The utility model relates to construction and can be used for extended structures, such as bridges, transport galleries, pipeline crossings, etc.n n n Known are the supporting parts of the bridge, including transmitting the vertical load in the structure from the span to the support with a tight touch, the hinge in the form of a spherical segment that rotates in the reciprocal recess and the upper and lower base plates interacting with an antifriction pair of slip layers, one of which is made of polished metal, and the other is made of anti-friction material.n n n The objective of the utility model is to increase the operational reliability, manufacturability and productivity of manufacturing the supporting part.n n n The supporting part of the bridge includes a vertical load transferring from the span to the support when the contact is tight, a hinge in the form of a spherical segment that rotates in the reciprocal recess and upper and lower base plates interacting with an antifriction pair of slip layers, one of which is made of polished metal and the other from - anti-friction material, for example ultra-high molecular weight polyethylene.n n n New in the utility model is the following.n n n The spherical segment is made in the form of a segment of a spherical shell with a cylindrical flange made of corrosion-resistant steel with an external polished surface, the inner part of which is partially filled, exceeding the line of transition from the sphere to the flanging, but not to its full height, with filler from the cured after filling the shell in liquid the aggregate state of the material, the parameters of the mechanical properties of which, after curing in the shell, its normalized minimum thickness are not inferior to similar parameters using In the bearing part for the sliding layers of antifriction material, and in the free surface of the hardened filler with a movable fit inside the flanging of the shell, exceeding its height, the distribution cylindrical insert is pressed with its end side, mating its opposite end flat side with the other part of the supporting part interacting with it, wherein the liner is connected by a lateral cylindrical surface, in particular with threaded screws, to said flange with the possibility of its vertically of displacement on the total amount of shrinkage and deformation of the filler during assembly and operation of the bearing.n n n The filler of the spherical shell segment may be concrete, in particular quick-hardening; fusible alloy, in particular eutectic; quickly hardening plastic, in particular acrylic. The distribution liner can be made both with a spherical and with a flat surface of the end side, pressed into the filler. The radius of the spherical surface of the end side of the liner is less than the inner radius of the spherical shell by the thickness of the hardened filler located in it. The other end side of the liner opposite to the filler can be made both with a sliding layer of antifriction material attached to it, and with at least one hole on this side, through which the liner can be rigidly fastened, for example, by a threaded connection, to another part of the supporting part . To enable vertical movement of the distribution liner when it is fastened with screws with a corrosion-resistant steel sheath, flanges are made with larger holes than the diameter of the connecting screws to the distribution liner, for example round or oval, covered by washers, and the hole sizes are assigned taking into account the total amount of shrinkage and deformation of the shell filler during assembly and operation of the support portion.n n n There may be cases when a segment with a through central axial bore may be required (for example, in supporting parts that accept a tear-off vertical force), then the spherical shell segment and the distributing insert can be made with central axial holes through which both of these elements are connected by a hollow cylindrical sleeve, located in the hardened filler. |
