Problems solved by technology

[0008] If it is heated for more than 1 day and the temperature is above 50-80°C, the delayed hardening epoxy resin grouting material will start to polymerize and harden rapidly, and the viscosity will increase, and it will not be able to smoothly inject and fill into the transparent connector sleeve, or it will not be able to Do proper prestressing

Embodiment Construction

[0031] Embodiments of the present invention will be described based on examples.

[0032] First, according to figure 1 The embodiment of the connecting structure part of the PC steel strand of the present invention is described, the symbol 2 in the figure is the connector sleeve made of transparent resin, made into a bottomed cylindrical shape with a main body part, and the inner diameter of the cylindrical shape is smaller than that of the connecting The outer circumference of the joint 3 is slightly larger, and the bottom of the cylinder is provided with an opening 51 for inserting the prefabricated cable and an injection port (A) 52 for delayed hardening epoxy grouting material, and a delayed hardening grouting material is provided on the cylindrical part. Discharge port (A) 53 for permanent epoxy resin paste material. In addition, a flange 55 is provided on the periphery of the opening of the transparent coupler cover (A) 2 for mounting the cover on a mounting member embe...

Abstract

A construction method and apparatus for the joint structure of twisted PC steel line is disclosed, which features that after said jonit structure is wrapped by a transparent jointer sleeve which has the grout inlet and outlet, the grout (It would be best if the epoxy resin with delayed hardening is used as the grout) is filled in said sleeve at a controlled temp. Its advantages are easily understanding the state of filled grout, and proper flowability and hardening time of grout.

Description

technical field [0001] The invention relates to a construction method and a construction device of a prestressed concrete (Prestressed Concrete, hereinafter referred to as PC) steel strand connection structure part in a prestressed concrete construction method. Background technique [0002] The connection part of the PC steel strand of the compression clamping method currently used is directly installed in the inside of the steel sleeve and buried in the poured concrete. The inside of the sleeve is filled with cement slurry material or resin slurry material after the PC steel strand is tensioned and fixed. Therefore, since the confirmation of the filling state inside the coupler housing is invisible after the concrete has hardened, it is impossible to confirm the filling state and repair it if a defect occurs, except for digging out the concrete. [0003] Therefore, since it cannot be seen from the outside at all, it is impossible to reliably check the filling state of the ...
