Description
Technical field
The utility model relates to the heavy type of International Classification of Patents patent classification E04B buildings in general constructing apparatus and correlation technique, especially concreting and opens string beam technical field, and especially the heavy roof system in plane is opened the string beam.
Background technology
In the known technology, tension string beam structure is to be proposed by Nihon University professor M.Saitoh the earliest, is a kind of novel hybridization roof system that is different from traditional structure.Tension string beam structure be a kind of by stiffening member wind up, flexible cable, centre connect the combination construction system that forms with strut, it is a kind of novel self equilibrium systems that its structure is formed, and is a kind of large-span prestressed space structures system.Tension string beam structure can be divided into plane tension string beam structure and space tension string beam structure by stressed; The plane tension string beam structure is meant that its structural element is positioned at same plane, and with stressed in the plane be master's tension string beam structure.The plane tension string beam structure can be divided into three kinds of citation forms according to the shape of last chord member: linear pattern is opened the string beam, arch is opened string beam, chevron shaped tension string beam structure.The linear pattern tension string beam structure is mainly used in floor slab structure and light grade roof structure, the arch tension string beam structure given full play to wind up encircle stressed advantage, be applicable to the roof structure of large span, chevron shaped tension string beam structure is applicable to the two sloping roof structure that span is less.The space tension string beam structure is to be the basic composition unit with the plane tension string beam structure, through the formed tension string beam structure of multi-form spatial placement.The space tension string beam structure mainly contains unidirectional tension string beam structure, two-way tension string beam structure, multidirectional tension string beam structure, radiant type tension string beam structure.Unidirectional tension string beam structure has guaranteed out-of-plane stability owing to be provided with the space-load system that the longitudinal bracing rope forms, and is applicable to the roof structure of rectangle plane.Two-way tension string beam structure has formed vertical and horizontal space-load system because crossing plane is opened the string beam resiliency supported is provided each other, and this structure is applicable to multiple plane roof structures such as rectangle, circle, ellipse.Multidirectional tension string beam structure is the space-load system that the plane tension string beam structure forms along a plurality of direction arranged crosswise, and this form of structure is applicable to the roof structure of circular and polygon plane.The radiant type tension string beam structure be by central authorities by the radial placement beam that winds up, the space-load system that strut is connected to form with the hoop rope is set under the beam, be applicable to the roof structure of circular flat or elliptic plane.The prestressed applying method of Prestressed Space steel work has two kinds usually.A kind of is directly to apply external force at prestressed cable, bar, thereby can improve structural stress state, causes redistribution of internal force, or forms a kind of new form of structure with the state of doing in certain; Another kind is to have built the space structures bearing discrepancy in elevation through adjustment, changes the size of bearing reaction, thereby structural internal force is heavily distributed, and reaches prestressed purpose.The material of prestressed cable, bar is divided into carbon steel rope, steel strand vang and rod iron usually.
The prestressing force beam string structure structure is as a kind of system of structure-bearing efficiently, by various construction projects particularly the roof system of large-span space structure adopt.
Tension string beam structure is the large-span prestressed steel work that grows up recent years, the new structure that is combined by string, strut and bending component.It has made full use of the overall structure stress performance that the high pull resistance of wringing has improved structure, becomes reasonable stress, makes convenient transportation, the simple self equilibrium systems of constructing, and is to have that applications well is worth and the new structure of prospect.Owing to prestressed introduction, the integral rigidity of structure improves greatly in tension string beam structure, and the size in cross section has obtained significantly reducing, but the stability of structure problem still can not be ignored.China's large span tension string beam structure has just begun to adopt.Its representative engineering is Pudong International Airport in Shanghai terminal steel roof truss that has completed for use and the Guangzhou international conference exhibition center exhibit halls steel roof truss of building.The stability problem of tension string beam structure can be divided into two types, and one type is the local stability of structure, and another kind of is the resistance to overturning of structure.The resistance to overturning of structure can be divided into resistance to overturning and the out-of-plane resistance to overturning in the plane again.
Light-duty string beam construction technology is comparatively ripe at home; Existence because of the heavy concrete floor in plane; Construction technology research for people's roof system on the heavy type of plane is less; Open the arrangement form that the string beam adopts the inverted triangle web member, wind up and adopt two parallel H Steel section members as the press-bending rod member, and corresponding with it be that a lower edge receives drag-line.The research of its construction technology still belongs to rare at home, no pertinent literature report.
Summary of the invention
The purpose of the utility model provides the heavy roof system tension string beam structure technology in a kind of plane.
Realize that the measure of the utility model goal of the invention comprises: connect the lower edge drag-line downwards in the roof beam structure both sides, adjacent lower edge drag-line bottom connects cable wire, and the cable wire two ends are connected with the roof beam structure two ends.
The advantage of the utility model is: made full use of the pull resistance of strand spiral rope, improved structure tension performance, constituted whole self equilibrium systems, construction is simple, and reasonable stress is made convenient transportation, and the integral rigidity of structure improves greatly, and sectional dimension obviously reduces.
