Abstract

The utility model discloses a kind of steel construction bow member, including domed bow member body, the bow member body is detachably connected along longitudinal direction by some section box beams and is formed, using splicing board component connection between box beam described in two adjacent sections.The splicing board component includes being arranged on the first splice plate on the inside of two adjacent sections box beam, the second splice plate being arranged on the outside of two adjacent sections box beam and bolt assembly, the side wall of two adjacent sections box beam is clamped by first splice plate and the second splice plate, and is locked by bolt assembly.Steel construction bow member of the present utility model is detachably connected using splicing board component, so that steel construction bow member is repeatable to be utilized, and greatlys save operating expenses.

Description

A kind of steel construction bow member
Technical field
This utility model is related to the assembled technical field of arch rib, in particular to a kind of steel construction bow member.
Background technology
Existing stiff skeleton method is, by cable crane and temporary towers drag-line, first to set up steel pipe stiff skeleton, profit With the bearing capacity of the steel pipe stiff skeleton for having set up, then high-strength concrete is irrigated in steel pipe, to further enhance its carrying Ability, then by the use of steel tube concrete soil skeleton as supporter, finally hangs mould and constructs to form armored concrete arch rib.
However, the armored concrete arch rib supported using support support or stiff skeleton, its steel pipe stiff skeleton is permanent Property structure, it is not possible to reuse, cause the cost of arch rib high.Particularly, when large span arch rib is built, to stiff skeleton Requirement for bearing capacity is higher, and the basic material and equipment of needs is more, further increases cost expense, extends construction period, Also there is potential safety hazard to surrounding enviroment ground.
Utility model content
The purpose of this utility model seeks to provide a kind of safe, operating expenses a kind of low steel construction bow member.
For achieving the above object, a kind of steel construction bow member designed by this utility model, including domed bow member body, The bow member body is detachably connected and is formed along longitudinal direction by some section box beams, box beam described in two adjacent sections be oppositely arranged each Using splicing board component connection between distinguishing between the wall of side.
Further, the splicing board component includes being arranged on the first splice plate on the inside of two adjacent sections box beam, is arranged on The second splice plate and bolt assembly on the outside of two adjacent sections box beam, first splice plate and the second splice plate are by adjacent two The side wall of section box beam is clamped, and is locked by bolt assembly.
Further, first splice plate and the second splice plate are steel plate.
Compared with prior art, this utility model has the advantage that:Steel construction bow member of the present utility model is using splicing Board component is detachably connected, it is possible to use steel of the laterally moved out steel construction bow member of a upper arch rib beam as next arch rib beam Structure bow member, so that steel construction bow member is repeatable to be utilized, and greatlys save operating expenses.
Description of the drawings
The structural representation of steel construction bow members of the Fig. 1 to set up in this utility model;
Fig. 2 is the mplifying structure schematic diagram of I in Fig. 1;
Fig. 3 is the mplifying structure schematic diagram of II in Fig. 2;
Fig. 4 is the sectional structure chart in Fig. 3 along A-A directions;
Wherein:1- bow member bodies, 2- box beams, 3- splicing board component, the first splice plates of 3.1-, the second splice plates of 3.2-, 3.3- bolt assembly.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As illustrated, a kind of steel construction bow member of the present embodiment, including domed bow member body 1, bow member body 1 is by some Section box beam 2 is detachably connected and is formed along longitudinal direction, between each side wall that two adjacent sections box beam 2 is oppositely arranged respectively between adopt Splicing board component 3 connects.Splicing board component 3 includes being arranged on the first splice plate 3.1 on the inside of two adjacent sections box beam 2, is arranged on The second splice plate 3.2 on the outside of two adjacent sections box beam, and bolt assembly 3.3, the first splice plate 3.1 and the second splice plate 3.2 The side wall of two adjacent sections box beam 2 is clamped, gap between two adjacent sections box beam 2 can be adjusted according to the curvature of corresponding arch rib, And locked by bolt assembly 3.3, the first splice plate 3.1 and the second splice plate 3.2 are steel plate.Steel construction arch of the present utility model Frame is detachably connected using splicing board component 3, it is possible to use the laterally moved out steel construction bow member of a upper arch rib beam is used as next The steel construction bow member of individual arch rib beam, so that steel construction bow member is repeatable to be utilized, and greatlys save operating expenses.
The above, specific embodiment only of the present utility model, it is noted that any to be familiar with those skilled in the art Member in the technical scope disclosed in this utility model, all should cover in this utility model by the change or replacement that can be readily occurred in Protection domain within.
