Background technology
Space truss structure is exactly a kind of spatial steel structure product being linked by node according to certain grid configuration by many rod members.Due to advantages such as it have space-load, lightweight, rigidity is large, anti-seismic performance is good; A kind of space structures that space truss structure is normally made up of two-way or three-dimensional plane frame, also by being four jiaos of reverse taper space structures that form with rod member.The former constructs simply, is applicable to the connection of node of various types simultaneously, as the Capital Gymnasium, International Club's indoor tennis stadium, and the roof structure such as the Shanghai Gymnasium building up recently, all belong to this type of.In general rectangle plane, the roof structure of large span (30～100 meters across), it is two-way more reasonable to adopt, because of rod member less, the simple feature of node processing.
In recent years, space truss structure is widely used as the roof structure in sports palace, exhibition hall, clubhouse, cinema, dining room, conference room, Waiting Lounge, hangar, workshop etc.Have industrialization degree high, from the feature of heavy and light, good stability, good looking appearance.Shortcoming is that to intersect at rod member quantity on node more, and fabrication and installation are compared with plane structure complexity, the especially sphere nodes in space truss structure, and welding difficulty is large, is difficult to guarantee welding precision.Reasonably install, welding procedure is particularly important to guaranteeing the construction of space truss structure, therefore, is necessary to propose a kind of new construction method for pipe truss in space truss structure and sphere nodes connection construction method.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of by adopting steel pipe column column cap and the pipe truss element piecemeal processing mode of integral solder in advance, reduce overhead welding workload, improve welding precision, reduction roof system pipe truss and steel pipe column welding difficulty are large, guarantee construction quality and safety, the roof system pipe truss of accelerating construction progress and syndeton and the construction method of steel pipe column.
For realizing above-mentioned technique effect, the invention discloses a kind of connection construction method of roof system pipe truss and steel pipe column, comprise the following steps:
Assembled single Pin roof system pipe truss;
Lower end at the assembled single Pin roof system pipe truss completing is welded to connect steel pipe column column cap;
Repeat above-mentioned construction sequence and complete being welded to connect of many Pin roof system pipe truss and steel pipe column column cap;
By jack truss connecting rod, adjacent Pin roof system pipe truss welding is assembled into roof system pipe truss lifting elements piecemeal;
The assembled roof system pipe truss lifting elements piecemeal completing is lifted, the steel pipe column column cap of described roof system pipe truss lifting elements piecemeal lower end is welded to connect to steel pipe column cylinder.
Described construction method is further improved and is, described single Pin roof system pipe truss comprise upper chord, lower chord and be welded in described upper chord and described lower chord between web member, described steel pipe column column cap is welded to connect to the lower end of described lower chord and described web member.
Described construction method is further improved and is, described steel pipe column cylinder is and is in tilted layout.
The syndeton that the invention also discloses a kind of roof system pipe truss and steel pipe column, comprises roof system pipe truss and steel pipe column, and described steel pipe column comprises cylinder and be welded in the column cap at described cylinder top, and described column cap is welded in the lower end of described roof system pipe truss.
Described syndeton is further improved and is, described in single Pin roof system pipe truss comprise upper chord, lower chord and be welded in described upper chord and described lower chord between web member, the top of described column cap is a sphere, and the lower end of described lower chord and web member is welded on described sphere.
The present invention has been owing to having adopted above technical scheme, makes it have following beneficial effect to be: taken into full account roof system pipe truss lifting elements from upper and lower chord member great, that be connected with steel pipe column and horizontal web member, connect that tie-rod is many and welding job amount is large.By taking steel pipe column column cap to separate with steel pipe column cylinder, steel pipe column column cap and upper and lower chord member, web member and jack truss are carried out assembled in advance, the mode of welding procedure after steel pipe column cylinder, reduce overhead welding workload, improve welding precision, reduce roof system pipe truss and steel pipe column welding difficulty large, guaranteed construction quality and safety, accelerated construction speed.
