Problems solved by technology

However, during the construction period, the actual vertical and horizontal slope of the bridge is limited by various factors such as the installation temperature of the beam body, the age of concrete prefabrication, and the specific quality of the pad stone. Pier deflection, cracking and other diseases endanger the safety of the bridge structure

Abstract

The invention discloses a slope self-adaptive spherical support. The slope self-adaptive spherical support includes an upper seat plate and a lower seat plate, wherein the lower seat plate is providedwith a spherical support body which is raised upwards in an arc-shaped mode, and the upper seat plate is arranged on the spherical support body. An arc-shaped groove which is concave inwards is formed in the bottom of the upper seat plate, the shape of the arc-shaped groove is suitable for the spherical support body, and the arc-shaped groove is in contact with the spherical support body in a matched mode. Compared with an existing spherical support, the slope self-adaptive spherical support has the advantages that the slope self-adaptive spherical support can automatically adapt to the beambottom longitudinal slope error and can save the consumption of beam bottom wedge-shaped leveling steel plates, the horizontal sliding surface level can be realized conveniently, and bridge repair andmaintenance are facilitated, so that the safety and durability of a bridge structure are realized.

Description

Technical field [0001] The invention relates to the development of a new bridge bearing, in particular to a slope self-adaptive spherical bearing. Background technique [0002] At present, pot bearings that meet the industry standard "Potted Bearings of Highway Bridges" (JTT391-2009) and spherical steel bearings that meet the national standard "Technical Conditions for Spherical Bearings" (GB / T 17955-2009) are due to It has high bearing capacity and stable quality. It has been used in our province for many years. It is mainly used in large-span structures such as cast-in-place box girders. For cast-in-place structures, as long as the support pad stone can be level, the performance of the support can be easily guaranteed. However, for prefabricated concrete beams and steel structure bridges, the horizontal sliding surface of spherical steel bearings and pot bearings is at the top of the bearings of the spherical steel bearings and pot bearings, and it is necessary to set a we...
