A steel spherical crown polymer mortar structure support and its construction method

Abstract

The invention discloses a steel plate spherical crown polymer mortar structure support and a construction method thereof. The support comprises a support padstone, a support body structure, a beam bottom embedded steel plate and a steel plate spherical crown polymer mortar structure located between the beam bottom embedded steel plate and the support body structure. The beam bottom embedded steel plate, the steel plate spherical crown polymer mortar structure, the support body structure and the support padstone are arranged from top to bottom. The support body structure is a polytetrafluoroethylene sliding plate type rubber support. The steel plate spherical crown polymer mortar structure comprises an upper padding plate, a spherical crown fixed to the upper portion of the middle of the upper padding plate, and a polymer mortar filling layer. The construction method comprises the following steps of 1, installing the beam bottom embedded steel plate, 2, surveying and setting out, 3, constructing the support padstone, 4, installing the support body structure, 5, constructing the steel plate spherical crown polymer mortar structure and 6, installing a main beam. The steel plate spherical crown polymer mortar structure support is reasonable in design, convenient to construct and good in using effect, and the problem that an existing support is prone to connection failure, unsymmetrical pressure and excessively-large partial deformation can be solved.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a steel spherical crown polymer mortar structure support and a construction method thereof. Background technique [0002] Bridge bearings are important components connecting the bridge superstructure and bridge substructure. Free deformation under the influence of factors such as temperature changes, concrete shrinkage and creep, and bridge bearings are directly related to the operational safety and service life of the bridge structure. [0003] In my country, plate rubber bearings have been developed and used since 1965, and have been used for 25 years. At present, they have become a widely used bearing form for domestic highways and urban bridges. Moreover, in 1988, the "Technical Conditions for Plate Rubber Bearings of Highway Bridges" (JT3132. In 1994, the Standards for Plate Rubber Bearings of Highway Bridges (JT / T4-93) were revised and promulgated ...
