Description
Technical field
The present invention relates to a kind of twin columns subsiding crack template and its installation methods.
Background technique
In the cast-in-place concrete constructions such as super-long structural concrete construction, to prevent because of differential settlement caused by building open
It mass defects, the design requirement such as splits and twin columns subsiding crack is generally set, therefore, the construction of subsiding crack is a routine and very heavy
The process wanted.
Traditional subsiding crack, which stays equipment, method mainly, following two kinds:
1, subsiding crack two sides are installed using plank sheathing, and seam inner template is removed after concrete formation.Due between subsiding crack
Distance is smaller, in addition lateral pressure acts in concreting process, molding rear pattern plate is removed very difficult.Stitch inner template often without
Method is removed.Lead to the functional requirement that not can guarantee subsiding crack in use process.
2, in pillar concrete construction, the materials such as cystosepiment are directly clogged in subsiding crack width range.Due to such material
Expect that intensity is lower, be easily destroyed or deform during concrete vibrating, it cannot be guaranteed that the effective width of subsiding crack is led to upper and lower
It is suitable, it is difficult to meet the functional requirement of subsiding crack.
From the above mentioned, if being stayed with conventional method, to set twin columns subsiding crack not only time-consuming, and quality is difficult to ensure.Especially
It is that conventional method, which is stayed, to be set subsiding crack difficulty of construction is big when twin columns are wider or section configuration is the compound sections such as the opposite sex, consumes
It is artificial more, certain difficulty is brought to rapid construction.
Summary of the invention
