Description

Ladder is hung to engineering that can divide segmentation to connect long

Technical Field

The utility model belongs to the technical field of open caisson engineering construction, concretely relates to ladder is hung to segmentable engineering that connects length.

Background

In municipal works, construction of a sunk well, a pipe-jacking working well, various inspection wells and the like is realized, workers mainly depend on temporary ladder stands to go up and down the well, but the depths of the wells are different, and particularly the height of the ladder stand needs to be continuously adjusted in the sinking process of the sunk well.

At present, when sinking construction of the open caisson in China is carried out, a frame body is usually erected on the outer side of the open caisson through a steel pipe for people to use up and down. Because of the open caisson structure is in the developments, the stair support body that outside steel pipe was set up leads to poor stability because of not having the wall facility that attaches, and along with constantly sinking of open caisson structure, its height still need constantly be adjusted to outside support body. Secondly, in various shaft structures like a pipe-jacking working well and the like, the way of pre-embedding U-shaped steel bars in the inner wall of the structure is adopted for the personnel to go up and down, the safety guarantee measures are poor, and the steel bar waste is large. Based on the analysis, similar to sinking of an open caisson, construction in a vertical shaft and the like, a hanging ladder which is universal, simple and convenient to manufacture, safe to use and flexible in configuration is needed.

Disclosure of Invention

Hang ladder length in order to overcome prior art in the open caisson work progress and can not adjust in a flexible way and lead to using inconvenient technical defect, the utility model provides a ladder is hung to segmentable extension's engineering, hangs ladder first section fixed connection at vertical structure's top, hangs ladder standard section and hangs and all be connected fixedly through couple and fastener between the ladder standard section to hang the technical problem that ladder length can not adjust in a flexible way in the open caisson work progress.

The utility model discloses a following technical scheme realizes above-mentioned purpose, a ladder is hung to segmentable extension's engineering, including hanging ladder head and hanging ladder standard section, hang the ladder head and be provided with on hanging ladder standard section and mark time, install the protection in one side of marking time and hang the net, hang ladder head and hang ladder standard section and adopt the round steel to pass through welded mode preparation, hang ladder head fixed connection at vertical structure's top, hang ladder standard section and hang and all be connected fixedly through couple and fastener between the ladder head and hang ladder standard section, it is connected fixedly through the side of linking wall mounting and vertical wall structure to hang ladder standard section.

The engineering hanging ladder capable of being lengthened in sections has the length dimension of the standard section of the hanging ladder as a standard value, and the length dimension of the standard section of the hanging ladder is preferably 2000mm-3000 mm.

Foretell ladder is hung to segmentation's engineering, hang the first section of ladder and hang through structural pre-buried reinforcing bar head between ladder standard section and the vertical structure, reinforcing bar head and the fastener firm in connection who hangs on the ladder, every section is hung the ladder and is fixed through upper and lower both ends totally 4 reinforcing bar heads and vertical structure.

The engineering hanging ladder capable of being lengthened in sections is characterized in that the protective hanging net comprises a waist block made of steel bar rings and a dense mesh safety net fixed on the waist block in a hanging mode.

Generally, through the utility model discloses above technical scheme who conceives compares with prior art, can reach following beneficial effect:

1. the utility model relates to a can connect long engineering hanging ladder by stage, usable job site steel bar welding, the on-the-spot material selection and processing are very convenient, utilize some reinforcing bar heads to make and link the wall mounting, this cat ladder can be according to the whole length of well depth control simultaneously, especially in the dynamic construction process such as the open caisson sinks, can expose the height adjustment hanging ladder overall height according to structures such as open caisson;

2. the utility model discloses the construction is simple rapid, installs and removes the convenience, can have enough to meet the need recycling, has certain spreading value in well construction field.
