Rapid tensioning device and method of prefabricated members on both sides of prefabricated station bottom plate

Abstract

The invention discloses a rapid tensioning device of prefabricated members on both sides of a prefabricated station bottom plate. The rapid tensioning device comprises a steel wire rope I and a steel wire rope II, wherein the steel wire rope I passes through tensioning holes I of the prefabricated members on the both sides, the steel wire rope II passes through tensioning holes II of the prefabricated members on the both sides, the upper end of the steel wire rope I and the upper end of the steel wire rope II are fixed respectively by reinforcing bars, both ends of a double-spliced angle iron are respectively connected to the lower end of the steel wire rope I and the lower end of the steel wire rope II, a pulley block of a sliding type electric hoist is arranged on the double-spliced angle iron, and a tensioning penetrating jack is connected to the lower end of the sliding type electric hoist. The invention further provides a rapid tensioning construction method. According to the rapid tensioning device, the construction risk is avoided, and the effect that the jack is rapidly positioned and is rapidly tensioned is achieved; the rapid tensioning device has the advantages of wide source of materials, simplicity in manufacturing, convenience in operation and high tensioning efficiency, and more economic benefits are provided for an enterprise; and the problem of large difficulty in operation is solved, the safety risk during construction is reduced, and the construction efficiency is improved.

Description

technical field

[0001] The invention relates to the technical field of prefabricated station construction, in particular to a rapid tensioning device and method for prefabricated components on both sides of a prefabricated station floor. Background technique

[0002] Prefabricated stations are generally constructed in the center of a bustling city. The main feature is that the station can be quickly assembled after excavation, shortening the exposure time of the foundation pit, speeding up the construction progress, and reducing the time occupied by the road.

[0003] The traditional B-block construction method is: use chain hoists and hooks to move the through-hole jack; the disadvantages of the traditional B-block construction method are: 1) low construction efficiency; 2) difficult operation; 3) poor working environment ; 4) Due to the heavy weight of the through jack and the narrow operating space, there are potential safety hazards in the construction process.
