Prestressed steel strand fixing frame and mounting and using method thereof

Abstract

The invention relates to a prestressed steel strand fixing frame and a mounting and using method thereof and belongs to the field of building construction operation machinery. The prestressed steel strand fixing frame comprises a first rack (1), a second rack (2) and a sliding limiting and fixing component (3), wherein each of the first rack (1) and the second rack (2) are square, the four sides of each of the first rack (1) and the second rack (2) are the same, and the surfaces of the first rack (1) and the second rack (2) are parallel and opposite to each other; the first rack (1) and the second rack (2) are provided with limiting rails (121) mounted with the sliding limiting and fixing component (3) in a matching manner; the first rack (1) and the second rack (2) are fixedly mounted with the sliding limiting and fixing component (3) in a matching manner to form the placement space of a steel strand coil (5); a steel strand outlet (101) is formed in the center of the first rack (1) in the penetrating direction; and the internal diameter of the steel strand outlet (101) is matched with the wire diameter of a steel strand (51). The prestressed steel strand fixing frame is adaptiveto the steel strand coils (5) of different sizes; and a bearing (4) is arranged at the steel strand outlet (101) to reduce the distortion force of the steel strand (51) and reduce friction so as to improve the construction quality and efficiency.

Description

technical field [0001] The invention belongs to the field of construction machinery and relates to a device for placing steel strands before unloading, in particular to a prestressed steel strand fixing frame and an installation and use method thereof. It is used for cutting steel strands during the construction of roads, railways, bridges, buildings and other projects. Background technique [0002] At present, the prestressing technology has been widely used in our country, and the prestressing structure has become a main structure in the field of engineering construction in our country. In the prestressing construction, the coils are generally fixed by temporary shelf tubes when the steel strands are unloaded. Frequent dismantling and erection are cumbersome, and there are potential safety hazards. [0003] The utility model of CN 201820622621 .7 discloses a fixing frame for steel strand unfolding operation, which includes a cuboid steel strand coil outer frame, the size ...

AI Technical Summary

Problems solved by technology

[0004] However, due to limitations in structural design, this utility model still has the following defects: 1. The overall stability of the fixing frame is poor and the safety is poor; Steel strand coil; 3. The friction between the steel strand and the steel bar at the position of the outlet hole causes wear and tear, resulting in damage to the steel strand, and even because the twisting force of the steel strand is too large, the steel strand is bent and broken, which cannot ensure the quality of the project; 4. When the steel strand is exported from the export hole, the friction force is large, the transmission speed is slow, and the construction efficiency is low; it is inconvenient to install and fix, and the work efficiency is low
