Integrated construction technology of adjustable tie beam and pier column and special formwork for construction

Abstract

The invention relates to an adjustable tie beam and pier stud integrated construction process and a special construction template. The special construction template comprises a pier stud template, a connecting template and a tie beam template, wherein a connecting template lower connecting plate is arranged on the bottom surface of the connecting template; a pier stud template upper connecting plate is arranged at the top of the pier stud template; the connecting template lower connecting plate is connected with the pier stud template upper connecting plate; the connecting template takes the shape of downward C formed by sequentially connecting a module III, modules I and a module II; the head parts of the modules I are connected with the tail part of the module II; a tie beam side connecting plate is arranged at the head part of the module II; a tie beam side connecting plate is arranged on the module III; one or more tie beam heightening modules are further arranged at the lower part of the connecting template; the tops of the tie beam pad heightening modules is connected with a tie beam bottom connecting module; a tie beam bottom connecting side plate is arranged on the tie beam bottom connecting module; the tie beam template comprises a tie beam side plate and a tie beam bottom template; and the end faces of the tie beam side and bottom templates are connected with the tie beam side and bottom connecting plates. The special construction template has the advantages that simultaneous casting construction of the tie beam and the pier stud of different heights is realized.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and in particular relates to a technology for the integrated construction of adjustable tie beams and pier columns and a special formwork for the integrated construction of adjustable tie beams and pier columns. Background technique [0002] In bridge engineering, the tie beam is a structure that connects two piles or columns, so that the two piles or columns are connected into a common force-bearing whole. During the construction process, due to the different heights of the tie beams from the ground, the general construction method is to pour the piers first, then adjust the pre-embedded reinforcement of the tie beams, formwork and pour the tie beams, and construct separately. There are great disadvantages in this way: 1. In this process, it is necessary to support the column formwork, pour concrete, and then build a scaffold (the ground needs to be leveled and compacted in advance),...

Problems solved by technology

There are great disadvantages in this way: 1. In this process, it is necessary to support the column formwork, pour concrete, and then build a scaffold (the ground needs to be leveled and compacted in advance), the bottom formwork of the supporting beam, the binding steel bars, the side formwork, and pouring. Concrete, the construction process is cumbersome, time-consuming and labor-intensive, which greatly reduces the construction progress; 2. The cost increases. When the tie beam is poured twice, it needs scaffolding support, site leveling, compaction, and concrete reinforcement when necessary, resulting in The construction party invests more manpower and materials; 3. Pre-buried the tie beam reinforcement, first poured the pier concrete, then straightened the tie beam reinforcement, then tied the tie beam reinforcement, and poured concrete, so that the reinforcement was bent many times and the force Reduced performance; moreover, tie beams and pier columns are not poured at one time, and their integrity is not good

Reduce the connection between the tie beam and the pier column
