Embodiment 1

[0037] The folding mobile ladder for installing a roof ceiling of the present invention includes a first straight ladder 1 and a second straight ladder 2 .

[0038] see now figure 1 , figure 1 It is a structural schematic diagram of the ladder of the embodiment of the present invention. As shown in the figure, the first straight climbing ladder 1 is provided with two parallel uprights, and a number of cross bars are arranged in parallel between the two uprights, and the cross bar between the top ends of the two uprights is made of the first steel pipe 4. welding and fixing; the pole length of the first straight ladder 1 is 1900mm. The distance between the crossbars of the first straight ladder 1 from the top is 300mm.

[0039] The 2nd straight climbing ladder 2 is provided with two parallel uprights, between the two uprights some crossbars are set in parallel, and the crossbars between the tops between the two uprights are welded and fixed with the 2nd steel pipe 5; The ve...

Embodiment 2

[0042] The manufacturing method of the folding mobile ladder for installing the roof ceiling of the present invention comprises the following steps:

[0043] a. Production of the first straight ladder 1:

[0044] figure 2 for figure 1 The sectional view of A-A in, image 3 for figure 2 Enlarged view of the P site in . Take two steel pipes of φ25x5mm and length of 1900mm to make two vertical poles of the straight ladder; take seven steel pipes of φ25x5mm and length of 385mm to make the cross bars of the straight ladder, and weld them evenly at a distance of 300mm from the top, and finally make the first one with a net width of 360mm within a growth of 1900mm For straight ladders, the top crossbar is not welded temporarily;

[0045] b. Production of the second straight ladder 2:

[0046] Figure 4 for figure 1 The sectional view of B-B in, Figure 5 for Figure 4 Enlarged view of the Q site in . Take two steel pipes of φ36x5mm and length of 1870mm to make two vertic...

Abstract

The invention discloses a folding moving reversed-V-shaped ladder for installing a roof ceiling. The folding moving reversed-V-shaped ladder comprises a first straight cat ladder (1) and a second straight cat ladder (2). The folding moving reversed-V-shaped ladder is characterized in that the first straight cat ladder (1) is provided with two parallel upright tubes, a plurality of cross bars are arranged in parallel between the two upright tubes, the second straight cat ladder (2) is provided with two parallel upright tubes, and a plurality of cross bars are arranged in parallel between the two upright tubes, wherein a first steel pipe (4) is arranged in a second steel pipe (5), and the top end of the first straight cat ladder (1) is movably connected to the top end of the second straightcat ladder (2). The folding moving reversed-V-shaped ladder for installing the roof ceiling and a manufacture method thereof have the advantages that a reversed-V-shaped ladder device is simple in thestructure and convenient to manufacture an operator only needs to stand on the third crosspiece on the ladder by feet and uses leg joints of the operator to move the reversed-V-shaped ladder for changing the position of the ladder in a small range when working without going down the ladder, the soft rope connection in the middle of the ladder ensures the stability of the ladder, the work efficiency is improved, the construction progress is speeded up, and the engineering costs are reduced.

Description

technical field [0001] The invention relates to a climbing ladder, in particular to a folding and moving ladder for installing a roof ceiling and a manufacturing method thereof. Background technique [0002] The roof ceiling can enhance the interior decoration effect and give people a beautiful enjoyment. Moreover, it can meet the requirements of the use function and hide the factors that are not in harmony with the indoor environment. Ceiling methods can be divided into direct ceiling, suspended ceiling, wooden keel ceiling, T-shaped metal keel ceiling, U-shaped metal keel ceiling, suspended ceiling, other ceilings and other structures. [0003] In March 2016, the Yunnan Coca-Cola project entered the construction stage of the Dalin construction. All the Dalin rooms are colored plate tile rooms, and the ceiling is a combination of metal keel and asbestos board. The height of the suspended ceiling of the colored tile house is 2.5m, and the suspended ceiling covers the roof ...
