Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a fixing structure of a vertical climbing ladder for steel structure installation. Background Art

[0002] With the continuous development of the construction industry, the structural forms of buildings are becoming more and more diversified, and steel structures are being used more and more widely in various types of buildings. Therefore, safety measures during the installation of steel structures are of paramount importance.

[0003] Conventional steel structure installation measures are to install vertical up and down channels on the main body of the steel structure. This channel is fixed to the steel column body and is used by construction personnel to go up to the top of the steel structure to perform a series of construction operations. The conventional fixing method is to weld the channel to the steel column body to ensure the reliability of the channel. In steel-concrete structures, due to cross-operation and process connection problems, the steel column is often installed and the steel bar binding begins, and the ladder needs to be removed immediately. At this time, the installed steel structure column is a two-story or multi-story column. When dismantling, it is necessary to climb to the top of the column for flame cutting and removal. The high-altitude operation takes a long time and is frequent, and the safety of personnel cannot be guaranteed.

[0004] Therefore, how to optimize the connection node between the ladder and the steel structure is a technical problem to be solved. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, the utility model provides a fixing structure of a vertical climbing ladder for steel structure installation.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a fixing structure of a vertical climbing ladder for steel structure installation, which is characterized by:

[0007] It comprises a straight square tube fixedly connected to the steel structure, an L-shaped square tube fixedly connected to the ladder and a latch; the straight square tube has a notch on the upper part facing the ladder, and latch holes are formed at relatively high positions on the upper parts of the two side walls; the free end of the L-shaped square tube is inserted downwardly into the straight square tube from the notch; the latch passes through the latch hole to limit the position of the L-shaped square tube above the L-shaped square tube; the end of the latch is connected to the ladder via a safety rope.

[0008] When the ladder needs to be connected to the steel structure, the L-shaped square tube is plugged into the straight square tube, and the latch is inserted to limit the position to complete the fixing of the ladder. When the ladder needs to be removed, just pull out the latch, lift the ladder and pull out the L-shaped square tube.

[0009] Furthermore, the depth of the notch is 1 / 3 of the length of the rectangular tube.

[0010] Furthermore, the ladder is made of two sections of parallel angle steels and transverse round steels evenly distributed therebetween.

[0011] Furthermore, the end of the latch is connected to the round steel via a safety rope.

[0012] Furthermore, the L-shaped square tube is formed by welding two mutually perpendicular square tubes.

[0013] Furthermore, the safety rope is an iron wire.

[0014] Furthermore, the rectangular tube is fixedly connected to the steel structure via a connecting pipe.

[0015] Compared with the prior art, the utility model has the following advantages or beneficial effects:
