Cover beam construction auxiliary device and method

Abstract

The invention relates to a capping beam construction auxiliary device which at least comprises two triangular support units which are used for being arranged on the two sides of a pier column in the length direction of a to-be-poured capping beam and can be assembled to form an integrated triangular bracket capable of synchronously moving in the length direction of the pier column; a steel supporting frame which surrounds the pier column to form a non-contact space used for containing the pier column, and the two ends of the steel supporting frame are connected to a bottom end frame body of the triangular bracket and a bearing platform located below the pier column correspondingly, so that external force borne by the triangular bracket is transmitted to the bearing platform through the steel supporting frame; and the triangular bracket is hoisted to the steel supporting frame in the mode that a gap is reserved between the triangular bracket and the pier column. The advanced modular solution thought of modern standardization is applied to the technical field of capping beam construction, and the capping beam construction process which is numerous and complicated in original construction system and tedious in on-site assembly steps is simplified to obtain the modular capping beam construction auxiliary system which is high in executability and high in stability.

Description

technical field [0001] The invention relates to the technical field of cover beam construction, in particular to an auxiliary device and method for cover beam construction. Background technique [0002] The cover beam is an important component connecting the upper and lower in the bridge structure. The dead load and live load of the superstructure are transmitted to the pier column and foundation through the cover beam. The cover beam is the connecting component between the bridge box girder and the pier column. The cover beam is the main stress-bearing part of the lower structure of the reinforced concrete simply supported beam bridge located on the top of the pier column. It bears the main supporting role of the bridge. Its construction quality is usually engineering The point of control. There are many construction techniques for the cap beam support, and each technique has its own specific function and technological process, and different construction techniques will pr...

Problems solved by technology

In addition, compared with the above-mentioned support method, another commonly used hoop method in the current construction technology of girder cover mainly uses sufficient static friction to bear the load. Although it has obvious advantages in terms of terrain conditions and installation height, However, the application of this method has great limitations. The hoop-type support has requirements on the shape of the pier column; because the value of the friction coefficient between the steel hoop and the pier column in the hoop cantilever beam is difficult to grasp, depending on the flatness of the pier column surface Depending on the degree or roughness of the hoop, the potential safety hazard of hoop slippage accidents during construction is prominent; in addition, in addition to stably assembling the hoop to the pier column, it is still necessary to install multiple longitudinal load-bearing beams and multiple horizontal conduction beams step by step. , multiple supporting trusses, and connecting frames are assembled to the pier columns respectively, which is not only difficult for high-altitude construction, but also has the problem of a huge construction system and cumbersome on-site assembly steps
