It is contemplated that reduce cost and a kind of string Zhi Mengang structures easy for construction are provided.
To reach above-mentioned purpose, what the present invention was realized in：A kind of string branch portal frame structure with adjustable support rod,
It is made up of agent structure chord branch part and strut part three parts, wherein agent structure includes tapered H-section steel column and become to cut
Face H profile steel beam.String branch part is connected between using reinforcing pull rod, reinforcing pull rod and agent structure and supporting rod part point using otic placode.Strut
Part by epimere steel pipe, hypomere steel pipe, ribbed stiffener, connecting plate, head plate, epimere punch connecting plate, high-strength bolt, sleeve, under
Section punch connecting plate and tube sealing composition；Epimere steel pipe upper end and connection plate weld of the agent structure beam with ribbed stiffener, hypomere steel
Two otic placodes are welded in pipe lower end, and otic placode is connected with the reinforcing pull rod of string branch part, hypomere steel pipe lower end welding head plate, epimere steel pipe
The epimere to punch among lower end punches connection plate weld, and high-strength bolt pass through hole, and nut portion and epimere punch connecting plate
Weld, in epimere steel duct, sleeve is tightened against epimere steel pipe epimere and punched at connecting plate nut portion, the weldering of hypomere steel pipe upper end
Connect hypomere to punch connecting plate, high-strength bolt punches connecting plate hole through hypomere, makes the hypomere connecting plate that punches hold out against with sleeve；When
After agent structure, pull bar and strut install, by turnbarrel, bolt is screwed out sleeve, screw out to after the length of setting
Connecting plate is punched in epimere and hypomere punches and welds tube sealing between connecting plate.
Citation form of the present invention can have a strut, two struts or several structure types of multiple struts；Can be in single span
Upper implementation can also step up implementation more；Pull bar can use round steel or steel cable.
Invention effect：
1st, the present invention increases reinforcing pull rod and strut on existing portal frame structure, is applied by increasing stay length pre-
Stress, mid-span deflection and column cap moment of flexure are reduced, improve the bearing capacity of structure, add the rigidity of structure.
2nd, present invention reduces integrally-built steel using amount；This structure node is simple, and material usage economy, stress is clear and definite,
It is easy for construction.
3rd, new structure proposed by the present invention is especially suitable for Large-span Portal Frame structure.
