Problems solved by technology

In the connection structure of large steel structure pins, it is usually necessary to use large pins. Due to the heavy weight of large pins, it cannot be installed directly by hand
Moreover, due to the limited space for working at heights, some machinery cannot be used, which makes the installation of large pins very troublesome

Embodiment 1

[0027] like figure 1 , figure 2 , image 3 As shown in the figure, a method for installing a pin shaft in a confined space of a large steel structure specifically includes the following steps:

[0028] S1: Make the guiding element and the mounting element. The guiding element is the round tube 1. The outer diameter of the round tube 1 is smaller than the diameter of the pin 3, and the difference is between 2-4cm. Both ends of the round tube 1 are polished and smoothed. 1 is placed on one end of the pin 3, so that the circular tube 1 and the pin 3 have the same central axis, and then the two are welded together to form a mounting element. A circular plate 8 is welded inside the end of the circular tube 1 away from the pin shaft 3 , a No. 1 rotary buckle 9 is installed on the circular plate 8 , and a No. 2 rotary buckle 10 is installed on the end of the pin shaft 3 away from the circular tube 1 .

[0029] S2: Weld the auxiliary plate 4 near the pin hole on the steel structur...

Embodiment 2

[0036] like figure 1 , Figure 4 , Figure 5 As shown in the figure, a method for installing a pin shaft in a confined space of a large steel structure specifically includes the following steps:

[0037] S1: Make guiding elements and mounting elements. The guiding elements are round steel 2. The outer diameter of round steel 2 is smaller than the diameter of pin shaft 3, and the difference is between 2-4cm. One end of the round steel 2 is provided with a connecting screw part 201, the connecting screw part 201 and the round steel 2 have a coaxial axis, and the other end of the round steel 2 is installed with a No. 3 rotating buckle 11. One end of the pin shaft 3 is provided with a threaded hole, the threaded hole and the pin shaft 3 have the same central axis, and the connecting screw portion 201 of the round steel 2 is threadedly installed in the threaded hole of the pin shaft 3, then the round steel 2 and the pin shaft 3 are combined into a Install the component, and the ...

Abstract

The invention discloses a large steel structure limited space pin shaft mounting method. The method specifically comprises the following steps that S1, a guide element and a mounting element are manufactured; s2, an auxiliary plate is arranged at the position, close to the pin hole, of the steel structure, a through hole is formed in the auxiliary plate, and the through hole is aligned with the pin hole; s3, a pulley mechanism is arranged on the auxiliary plate, so that a sliding groove in one side of a pulley in the pulley mechanism is aligned with the through hole and the pin hole; s4, the installation element is hoisted to the position close to the pin hole, and the small-diameter end of the installation element is plugged into the pin hole; s5, two chain blocks are prepared and comprise the first chain block and the second chain block, a lifting chain block of the first chain block penetrates into the pin hole to be connected with the small-diameter end of the installation element, and a lifting chain block of the second chain block is connected with the large-diameter end of the installation element; s6, pulling a hand-pulled chain of a chain block I, and pulling the mounting element into a pin hole; according to the invention, the installation of the large pin shaft of the large steel structure can be very conveniently realized in a high-altitude limited space.

Description

technical field [0001] The invention relates to the field of pin shaft installation of steel structures, in particular to a pin shaft installation method in a limited space of a large-scale steel structure. Background technique [0002] With the development of society, especially the continuous development of science and technology, the rapid development of social productivity has been greatly promoted; especially the rapid rise of steel structure buildings has injected new vitality into the rapid development of the construction industry. [0003] Pin connection in steel structure refers to the node form in which the pins are used to connect multiple lugs connected to multiple adjacent members, and it is a common connection method in steel structures. The size of the pin is positively related to the force that the pin needs to bear. In the connection structure of large-scale steel structure pins, large-scale pins are usually used. Due to the large weight of large-scale pins...
