Abstract

The invention discloses a checking tool for a jack. The checking tool for the jack comprises a baffle. A supporting leg is arranged on one side of the baffle, and the jack is arranged on the supporting leg. The jack is connected with a tensioning rod through a connection nut. A guide hole is formed in the middle of the baffle, and the tensioning rod penetrates through the guide hole. A steel plate ring is arranged on the other side of the baffle. A tensioning plate connected with the tensioning rod is arranged in the steel plate ring. A bar hanging plate is arranged on the tensioning plate and connected with a steel bar. The tensioning rod is provided with a tension checking mechanism. The tensioning plate is provided with a displacement checking mechanism. The steel plate ring is provided with a wire slippage monitor mechanism corresponding to the steel bar. By checking the tensioning length and tensioning force and monitoring the tensioning quality, high-quality construction in the tensioning process is ensured; and through cooperation of checking on the tensioning length and the tensioning force and monitoring on the tensioning quality, the purposes that the cement consumption of electric poles is correspondingly reduced, the weight of the electric poles is gradually reduced, and the cracking resistance, ductility and rigidity are gradually improved are achieved, and meanwhile the service life of the electric poles can be prolonged.

Description

technical field

[0001] The invention relates to the technical field of concrete product manufacture, in particular to a jack checking tool. Background technique

[0002] With the continuous development of modern power grid construction and communication technology, high-strength, large bending moment, and long-length annular concrete poles are constantly being used, and the maximum has reached 45m. Over the years, reinforced concrete poles have inevitably been used in production, transportation, and operation. Circumferential cracks appear. Although it is stipulated in Table 6 of the National Standard GB / T 4623-2006 "Circular Concrete Pole" of the People's Republic of China: reinforced concrete poles must not have longitudinal cracks, and the width of circumferential cracks must not exceed 0.05mm, and Article 6.5.1 stipulates: When the reinforced concrete pole is loaded to cracking test bending moment, the crack width should be less than 0.2mm. This is a corollary of the s...
