Problems solved by technology
[0002] At present, large-span steel structure factory buildings have been widely used, but the construction of bridges and pipelines in electromechanical machinery is becoming more and more difficult. Conventional brackets have the following shortcomings: ①The brackets are difficult to manufacture and install, and the weight increases the load of the factory building; ②The production of conventional brackets uses more materials, which increases the cost; ③The production and installation period of conventional brackets is long and takes up space, which greatly affects the construction period and the appearance of the factory building

Embodiment Construction
[0020] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:
[0021] as attached figure 1 As shown, an adjustable support device for cable-stayed steel suspension cables in a super-large-span steel structure includes two fixed brackets 2, four cable-stayed steel suspension cable rods 5, four adjustment devices 4, and a support tray 3 .
[0022] The fixed bracket 2 is separately arranged on both sides of the adjustable supporting device of the cable-stayed steel suspension cable, and one end of the fixed bracket 2 is provided with a pre-embedded pad iron 1, which is welded by using the pre-buried pad iron 1 on the steel structure column in the workshop The fixed bracket 2 fixes one end of the fixed bracket 2 on the steel structure construction column. Bolt holes are reserved at the corresponding positi...

The invention discloses a cable-stayed steel suspension cable adjustable supporting device in a super-long-span steel structure and a method. The cable-stayed steel suspension cable adjustable supporting device in the super-long-span steel structure comprises two fixing brackets arranged on the two sides correspondingly, at least two cable-stayed steel suspension cable pulling rods are arranged oneach fixing bracket, an adjusting device is arranged on each cable-stayed steel suspension cable pulling rod, and a supporting pallet is arranged between the every two cable-stayed steel suspension cable pulling rods on the two sides. According to the cable-stayed steel suspension cable adjustable supporting device in the super-long-span steel structure and the method, the steel suspension cableadjustable supporting device is arranged on a steel-structure structural column, a bridge frame and a pipeline are placed on the pallets, stability of the pallets is adjusted by cooperating with a steel suspension cable, and the problems of rooting without a ground of the brackets in a large span workshop, reducing of construction efficiency and increasing of construction cost are avoided; and thesituation of rooting without the ground can be avoided through the steel suspension cable adjustable supporting device, the construction efficiency is improved, the construction cost is reduced, theconnecting mode of the steel suspension cable adjustable supporting device adopts welding and bolt connection, prefabrication in advance can be achieved, and the construction period can be greatly shortened.
Description
technical field [0001] The invention relates to a supporting and guiding device, in particular to an adjustable supporting device and a supporting method applicable to the laying of bridges, trunkings and pipelines in super-long-span steel structures. Background technique [0002] At present, large-span steel structure factory buildings have been widely used, but the construction of bridges and pipelines in electromechanical machinery is becoming more and more difficult. Conventional brackets have the following shortcomings: ①The brackets are difficult to manufacture and install, and the weight increases the load of the factory building; ②The production of conventional brackets uses more materials, which increases the cost; ③The production and installation period of conventional brackets is long and takes up space, which greatly affects the construction period and the appearance of the factory building. Contents of the invention [0003] The purpose of the present inventio...
