Embodiment Construction

[0017] The present invention will be described in further detail below in conjunction with examples and with reference to the accompanying drawings.

[0018] A steel truss bridge member space angle adjustable hanger, composed of a main force and adjustment device and an auxiliary adjustment device, wherein:

[0019] The main stress and adjustment device is composed of upper main stress sling 1, upper snap ring 3, upper lug 4, lower main stress sling 2, lower heavy turnbuckle bolt 13, lower snap ring 16 and lower lug 17. Both the upper end of the main stressed sling 1 and the upper end of the lower main stressed sling 2 are hung on the hook 8 of the beam erecting crane, and a snap ring with a belt is fixed on the web axis 10 at the top of the web 5 at a spatial angle. 3's upper lug 4, the lower end of the upper main stressed suspension rope 1 is connected with the upper lug 4 through the upper snap ring 3; the lower lug with the lower snap ring 16 is fixed on the web axis 10 at...

Abstract

The invention discloses a suspender capable of adjusting the spatial angle of a rod member of a steel truss bridge. The suspender comprises a main bearing and adjusting device and an auxiliary adjusting device, wherein, the main bearing and adjusting device comprises an upper main bearing lifting rope, an upper snap ring, an upper hanger, a lower bearing lifting rope, a lower heavy type turn buckle, a lower snap ring and a lower hanger, and the auxiliary adjusting device comprises a left auxiliary adjusting lifting rope, a left leading chain, a left snap ring, a left hanger, a right auxiliary adjusting lifting rope, a right leading chain, a right snap ring and a right hanger. According to the invention, the weight of a spatial angle web member is mainly borne by the two main bearing lifting ropes, an included angle between the vertical axis of the spatial angle web member and a horizontal plane is adjusted through the lower heavy type turn buckle, the transverse space horizontal angle of the spatial angle web member is adjusted through the left and right leading chains, and therefore, the purpose of adjusting the spatial angle of the spatial angle web member is realized. The suspender is especially applicable to hoisting of a spatial angle web member of an inclined main girder steel truss bridge and has the advantages of simple construction, definite bearing, convenient operation and high working performance.

Description

technical field [0001] The invention relates to bridge construction equipment, in particular to a hanger with adjustable spatial angles of steel truss bridge members. Background technique [0002] With the development of science and technology in our country, the application of "four new" technologies such as new technology, new material, new process and new equipment has resulted in the emergence of a large number of bridge projects with novel structures. In recent years, long-span steel bridges have developed a new type of structure - inclined main truss steel truss bridges, which put forward new requirements for the installation of steel truss bridges. [0003] Ordinary vertical main truss steel truss bridges, the webs are generally "I"-shaped or box-shaped, located in the vertical plane, the installation method is usually as follows: (1) Lift the web vertically, insert the gusset plate vertically downward ; (2) Aim at a bolt hole and drive in the punching nail; (3) Take...
