Abstract
The invention provides an open-web overhanging truss structural system with unequal-height chord members. The open-web overhanging truss structural system with the unequal-height chord members comprises steel columns and steel chord members, wherein the steel chord members are connected to the steel columns from bottom to top in sequence; the steel chord members are provided with overhanging sections which are connected with the steel columns at the outermost side; the outer side of each overhanging end section is connected with a vertical web member; the steel columns at the outermost side, the upper steel chord members, the lower steel chord members and the vertical web members form a rectangular structure; and the steel chord members are different from the adjacent upper and lower steel chord members by height. The open-web overhanging truss structural system with the unequal-height chord members, provided by the invention, realizes a large-span overhanging building effect under the condition of ensuring the bearing capacity and meeting the requirement of the policy to utilization, and meets the requirement on utilization of the space of the building.
Description
Technical field
The present invention relates to the steel truss structure system, especially a kind of empty stomach Steel Cantilever Truss structural system.
Background technology
Trussed construction is the structural shape realizing large span in many Bases in High Building Constructions, encorbelment greatly and a kind of structural system of generally adopting.The enforcement of the scheme of the whether reasonable directly impact building that trussed construction uses in the total engineering.Development along with social economy and science and technology, urban architecture has obtained faster development, design of building structures is had higher requirement, traditional girder system is restricted owing to the existence of diagonal web member makes architect's function that fixes one's room up, particularly relatively good at some views, the position that location comparison is special, this contradiction is obvious all the more, the architect does not wish that diagonal web member affects it and arranges, and encorbelments or the yardstick of striding greatly is unwilling to compromise.
Under this background, conventional girder system is improved, because different building storeys are different to the requirement for height of structural element, adopt the common space empty stomach truss structure system that forms of not contour chord member cross section and perpendicular web member to realize Long-span Cantilever, reasonably cross section and construction measure have guaranteed the whole stressed of structure, have satisfied and have built the instructions for use that does not have diagonal web member.
Summary of the invention
The relatively poor deficiency of space result of use of when designing Vierendeel truss, using diagonal web member to cause in order to overcome existing steel truss structure system, the invention provides under a kind of condition that guarantees bearing capacity and policy instructions for use, realize the architectural effect of Long-span Cantilever, satisfy the not contour chord member empty stomach Steel Cantilever Truss structural system of the space instructions for use of building.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of not contour chord member is Steel Cantilever Truss structural system on an empty stomach, comprise steel column and string wire bar, described string wire bar from bottom to top according to hierarchical linkage on steel column, described string wire bar is provided with the section of encorbelmenting, the described section of encorbelmenting is connected with the outermost steel column, outside of each end section of encorbelmenting is connected with perpendicular web member, outermost steel column, up and down string wire bar and perpendicular web member formation rectangle structure, the string wire bar and adjacent about the height of string wire bar unequal.
Further, from bottom to top, the height of each string wire bar uprises gradually.Certainly, also can select other not contour mode, as long as satisfy the floor height space requirement.
Technical conceive of the present invention is: not contour chord member of the present invention on an empty stomach Steel Cantilever Truss structural system is a kind of improved trussed construction system, this modified invention, take full advantage of the structure chord member cross section that different construction floors allow employing, form the larger space structures of space stiffness.This girder system is comprised of the rigid connection node of the chord member of different cross section, perpendicular web member and chord member and perpendicular web member; This structural system effectively utilizes the space, the particularly height of roofing part chord member that building allows, and makes the rigidity of whole Vierendeel truss can be enough to satisfy bearing capacity and normal instructions for use.Thereby realize the building requirements of Long-span Cantilever, and the structure of each connected node rigidity is to guarantee its feasible main points.
Beneficial effect of the present invention: not contour chord member empty stomach Steel Cantilever Truss structural system of the present invention is by changing the pattern of conventional trussed construction, by adopting not contour chord member cross section and rational construction measure, under the condition that guarantees bearing capacity and normal instructions for use, so that cantilever frame can be realized the requirement of Long-span Cantilever, can satisfy again at architecture indoor cancellation diagonal web member, thereby not affect the requirement of building usage space.This structural system simple structure, easy construction can be applicable to Long-span Cantilever position civilian, commercial, industrial construction.
Description of drawings
Fig. 1 is open-web truss structure layout schematic diagram.
Fig. 2 is the open-web truss structure generalized section.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
See figures.1.and.2, a kind of not contour chord member is Steel Cantilever Truss structural system on an empty stomach, comprise steel column 1 and string wire bar 2, described string wire bar 2 from bottom to top according to hierarchical linkage on steel column 1, described string wire bar 2 is provided with the section of encorbelmenting 3, and the described section of encorbelmenting 3 is connected with the outermost steel column, and each outside of encorbelmenting end section 3 is connected with perpendicular web member 4, the outermost steel column, string wire bar and perpendicular web member form rectangle structure up and down, and string wire bar 2 is unequal with the height of adjacent up and down string wire bar.
Further, from bottom to top, the height of each string wire bar 2 uprises gradually.Certainly, also can select other not contour mode, as long as satisfy the floor height space requirement.
In the present embodiment, this truss pattern is intended to give full play to the advantageous effect of the space structures that each not contour chord member forms, and particularly is positioned at the effect of the larger string wire bar 2 in the cross section of roofing, has solved the space defective that conventional truss has diagonal web member.This structural system simple structure, easy construction.Implementation as depicted in figs. 1 and 2.This hollow steel truss is comprised of not contour section steel chord member 2 and perpendicular web member 4.
Claims (2)
1. not contour chord member Steel Cantilever Truss structural system on an empty stomach, comprise steel column and string wire bar, described string wire bar from bottom to top according to hierarchical linkage on steel column, it is characterized in that: described string wire bar is provided with the section of encorbelmenting, the described section of encorbelmenting is connected with the outermost steel column, outside of each end section of encorbelmenting is connected with perpendicular web member, outermost steel column, up and down string wire bar and perpendicular web member formation rectangle structure, the string wire bar and adjacent about the height of string wire bar unequal.
