Support frame for mounting precast beam jack

Abstract

The invention provides a support frame for mounting a precast beam jack. The support frame at least comprises a primary support frame and a working platform arranged on the primary support frame, and also comprises a secondary support frame, wherein the secondary support frame is reliably connected with the primary support frame; the support frame also comprises a rail which is longitudinally arranged on the primary support frame and the secondary support frame, and a lifting system which is arranged on the rail, can move along the rail and is used for lifting the jack; the rail can transversely move on the primary support frame. The jack can be rapidly transported to a specified place in the precast beam site in a labor-saving mode and can be rapidly and accurately aligned, and the working efficiency is improved.

Description

technical field [0001] The invention relates to a construction auxiliary tool for a prefabricated beam field, in particular to a support frame for installing a prefabricated beam jack. Background technique [0002] At present, the use of jacks in the prefabricated beam field is a very important process for prestressed tensioning of prefabricated beams. Jacks are required when tensioning prefabricated beams. Due to the great weight of the jack, a large amount of equipment and manpower are required for its handling. , time-consuming and labor-intensive; therefore, in the current prefabricated beam field, tensioning brackets are used for prestressed tensioning of prefabricated beams. [0003] Most of the existing tension supports are welded by steel bars and ordinary steel pipes, and there are no relevant protection measures, so that the safety of the staff cannot be effectively guaranteed, and it also directly affects the construction safety and efficiency. In order to solve ...

Problems solved by technology

The tensioning trolley installs jacks on beams of different heights through the hoist and the tensioning workbench; this device cannot move the preparatory jack into the workbench efficiently and quickly in the preparation before work, or it needs to rely on other auxiliary machinery and a lot of manpower to move the jack to the workbench; when installing the jack, the hoist crane can only move up and down and back and forth, so the positioning of the jack is difficult, which affects the construction efficiency

The patent document with the publication number CN202053373U discloses a prefabricated beam tensioning flat car in the prefabricated field. The flat car is composed of steel pipes to form a steel frame platform, and a liftable chain hoist is installed above the steel frame platform. The chain hoist is connected to the jack. The steel pipe frame platform on the corresponding side of the jack is equipped with a steel plate, and the tensioning platform car is also equipped with universal wheels. On the one hand, changing the tensioning platform still cannot solve the problem of how to quickly and effortlessly transport the jack to the working platform. , when aligning the jack, the position of the jack can only be adjusted by the movement of the tensioning platform vehicle, and then the staff can use the hand chain hoist to install the jack, because the vehicle cannot be accurately controlled when the vehicle is moving The size of the stroke, so the position of the jack is difficult to align, the efficiency is low, and the manpower consumed by the movement of the whole vehicle is also huge
