Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
Fig. 1-4 illustrate an embodiment of the present invention.
As shown in fig. 1 to 4, a temporary ladder for prefabricated construction includes: cat ladder body 1, sleeve 4, retractable pole setting 5, lug 10 and guardrail 11.
The crawling ladder body 1 is formed by welding square steel pipes and is used for operators to go up and down; bolt holes are formed in the left side and the right side of the upper portion of the main keel and used for connecting the ladder stand body 1 with the sleeve 4; the bottom of cat ladder body 1 is equipped with mounting panel 2 along transversely, is equipped with first bolt hole 3 on the mounting panel 2 for the cat ladder is connected with the prefabricated staircase of having installed.
The telescopic vertical rod 5 is made of a steel pipe, the top of the telescopic vertical rod is provided with a connecting part 6, the connecting part 6 is provided with an external thread matched with the internal thread, and the connecting part 6 is in threaded connection with the sleeve 4; the middle part is provided with a telescopic part 7 for adjusting the height of the ladder stand according to the height of the floor; the bottom is equipped with L type installation department 8, is equipped with second bolt hole 9 on the horizontal part of L type installation department 8 for fixed retractable pole setting 5 is connected with the prefabricated stair of having installed.
The lifting lugs 10 are made of plain steel bars, are arranged at the upper ends of the two sides of the crawling ladder body 1, are welded with the crawling ladder into a whole and are used for hoisting the crawling ladder; guardrail 11 is formed for the pipe welding, and is whole with cat ladder welding, and the guardrail is located cat ladder and faces empty one side for the handrail about the operation personnel.
The implementation steps of this example are as follows:
