Description

Technical Field

[0001] This utility model relates to the field of steel support technology, specifically to a stable arc-shaped steel support. Background Technology

[0002] With the development of infrastructure, bearings have been widely used in bridges and buildings. They are important equipment for vibration reduction and isolation of bridges and buildings (steel bearings). Bearings are set between the foundation and the superstructure of bridges and buildings to bear the weight of the superstructure, fix the relative position of bridges and buildings, and constrain or release rotation and displacement.

[0003] Meanwhile, during the assembly of buildings (such as bridge piers and viaduct piers), the upper part is supported and rotated by steel supports. The steel supports are supported by two arc surfaces, which makes the contact surface unstable and prone to tilting, resulting in unstable operation. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3This utility model provides a technical solution: a stable arc-shaped steel support, comprising: a steel-concrete support base 1 and an upper steel platform 2;

[0024] The lower side of the outer wall of the reinforced concrete support base 1 is provided with a fixed skirt 3. Fixed connection holes are evenly and longitudinally opened on the fixed skirt 3. The upper surface of the reinforced concrete support base 1 is a concave arc surface. A insertion groove 5 is longitudinally opened in the middle of the upper surface of the reinforced concrete support base 1. The upper steel platform 2 is located on the upper surface of the reinforced concrete support base 1, and the lower surface of the upper steel platform 2 is provided with a convex arc surface that matches the upper surface of the reinforced concrete support base 1. A support column 11 that matches the insertion groove 5 is provided on the lower surface of the convex arc surface. The support column 11 is rotatably connected to the insertion groove 5.

[0025] Analysis of the above content: In use, the steel-concrete support base 1 is connected and fixed to the pre-embedded screws on the ground through fixed connection holes and nuts. Then, the upper steel platform 2 is placed on the upper side of the steel-concrete support base 1, so that the two arc surfaces slide support, and the support column 11 is inserted and matched with the insertion slot 5 to connect the upper building structure to the upper part of the upper steel platform 2.

[0026] like Figure 2 As shown, a polytetrafluoroethylene (PTFE) layer 4 is provided in the recessed area on the upper surface of the steel-concrete support base 1. The PTFE layer 4 has a wear-resistant and smooth function, which reduces the resistance between the steel-concrete support base 1 and the upper steel platform 2 during relative operation.

[0027] like Figure 3 As shown, the lower surface of the convex arc surface is coated with a lubricating oil layer 10. The lubricating oil layer 10 further reduces the frictional resistance between the steel-concrete support base 1 and the upper steel platform 2.

[0028] like Figure 1 , 3 As shown, a side protective skirt 9 is provided on the lower side of the outer edge of the upper steel platform 2. The side protective skirt 9 is located on the upper side of the reinforced concrete support base 1. A fastening bolt 12 is threaded onto the side protective skirt 9. The fastening bolt 12 passes through the side protective skirt 9 and contacts the outer wall of the reinforced concrete support base 1. After rotating to a suitable position, the fastening bolt 12 is tightened. The end of the fastening bolt 12 contacts the outer wall of the reinforced concrete support base 1. The isomorphic friction keeps the reinforced concrete support base 1 and the upper steel platform 2 stable. Then, the reinforced concrete support base 1 and the upper steel platform 2 can be further fixedly connected by welding.

[0029] like Figure 1 As shown, an anti-slip friction ring 6 is provided around the upper circumference of the outer wall of the reinforced concrete support base 1. After the anti-slip friction ring 6 contacts the end of the fastening bolt 12, the reinforced concrete support base 1 and the upper steel platform 2 are not easy to slide relative to each other.

[0030] like Figure 1 , 3 As shown, the top of the upper steel platform 2 is provided with an upper support connecting plate 7, and the edge of the upper support connecting plate 7 is also provided with fixed connection holes evenly and longitudinally. The lower surface of the upper support connecting plate 7 is provided with a connecting rod 8, and the bottom end of the connecting rod 8 is inserted into the steel-concrete support base 1.

[0031] The upper support connecting plate 7 is used to connect with the upper building structure. The upper support connecting plate 7 is also connected to the upper building by pre-embedded screws and nuts. The steel structure of the steel-concrete support base 1 and the connecting rod 8 are pre-connected. Then, concrete is poured around the steel structure of the steel-concrete support base 1 and the connecting rod 8 until it is formed, so that the steel structure of the steel-concrete support base 1 and the connecting rod 8 are connected as one.

[0032] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
