Detailed Description

The present invention will be further described with reference to the following examples. The following description of the embodiments is merely provided to aid in understanding the invention. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, the present invention can be further modified and modified, and such modifications and modifications also fall within the protection scope of the appended claims.

The utility model discloses a bent cap core-piercing rod stores pylon formwork system through adopting pre-buried PVC pipe 9, sets up a through-hole that runs through the thin wall mound at the top of thin wall mound 14, will wear core rod 5 to pass PVC pipe 9, erect the triangle bearing bracket of prestressing force processing at the both ends of wearing core rod 5, utilize triangle bearing bracket to form the support, installation distribution roof beam and bracket 4, after distribution roof beam and the 4 counter-force pre-compaction of bracket, erect die block 2 and side form 1, pour the concrete to form solid mound bent cap.

Compared with the traditional construction method, the bent cap core rod-penetrating hanging rack formwork system has simpler construction process and strong repeatability, and is beneficial to the skillful grasp of operators; the construction period is short, the required components are produced in a factory, the prestress treatment is carried out on partial components, and the quality is easy to guarantee.

In order to guarantee the effort equilibrium of triangle bearing frame to the thin wall mound, the utility model discloses in innovated PVC pipe 9's structure for its plane positional deviation is less than or equal to 5mm, and the high error of PVC pipe is less than or equal to 5mm, thereby in order to guarantee PVC pipe 9's levelness.
