Abstract
The invention discloses a method for supporting a factory-building roofing system at a huge pumping column space, which relates to the technical field of construction structure design. According to normal column space (6), an on-beam steel column (2) is added in corresponding position on the top surface of a large box-shaped crane beam (1) at the huge pumping column space (7); the top of the on-beam steel column (2) is articulated with a steel roof truss (3), and the foot of the on-beam steel column (2) is articulated with the large box-shaped crane beam (1). The method effectively solves the problem of how to support a factory-building roofing system at a huge pumping column space and causes the arrangement of the roofs to be more unified and the whole rigidity of the factory buildings to be evener, thereby achieving good technical effect and economic benefits. The method is mainly used for the design of the supporting of a factory-building roofing system at a huge pumping column space.
Description
Technical field
The present invention relates to the design of building structures technical field, particularly a kind of method for supporting that is applied in the super large column-removed spacing factory building roof system of individual layer industry steel-structure factory building.
Background technology
General, the basic post of individual layer industry steel-structure factory building apart from how between 6～15m, but continuous expansion along with social demand, needs for the layout that satisfies the ultra-large type production equipment and vanguard technology development, the post distance that needs bigger even super large in the individual layer industry steel-structure factory building, local even reach more than the 40m.In this case, increasing factory building columns will be taken out in the factory building part, and how this place's Roof system supports and also become insoluble problem in the mill construction design gradually.
Conventional way with this type of problem of pre-treatment is: carriage is set promptly is commonly called as beam to support the steel roof truss or the roof girder of relevant position taking out the post place, the carriage two ends place takes out factory building columns top, post both sides.This kind way is more suitable with the lower prop distance for handling 24m, but for the ultra-large type column-removed spacing more than the 30m, if still in this way, the depth of section of carriage can be very big so, steel using amount increases a lot, and, further increasing investment because joist cross section height certainly will cause the lifting of factory building whole height, comprehensive benefit is bad.It is very little to take out outside the upper prop plane of factory building columns of post both sides rigidity simultaneously, is difficult to probably bear the load that carriage transmits, and causes the more structural problem.
Summary of the invention
The object of the present invention is to provide a kind of method for supporting of super large column-removed spacing factory building roof system, can solve the problem how individual layer industry steel-structure factory building ultra-large type column-removed spacing place Roof system supports, reach safe, suitable, economic purpose.
The technical solution adopted for the present invention to solve the technical problems is: on large-scale box-shaped crane girder (1) end face of super large column-removed spacing place (7), increase beam on steel column (2) apart from (6) in its relevant position by normal post, (2) capital of steel column on the beam and steel roof truss (3) are hinged, and suspension column and large-scale box-shaped crane girder (1) are hinged.
The invention has the beneficial effects as follows, the inherent characteristics that utilizes the super large column-removed spacing place is that column section and rigidity are big under the factory building of both sides, box-shaped crane girder cross section is big also mainly to be controlled by amount of deflection, less by the steel roofing load that post transmits to its influence, make force path succinct more, clear and definite, thereby well solved the problem how the super large column-removed spacing factory building roof system supports, and made that the layout of roofing is also more unified, it is even that the factory building integral rigidity more is tending towards.Not only reached good technical effect, favorable economic benefit has also been arranged.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a kind of structural representation of method for supporting of super large column-removed spacing factory building roof system;
1. box-shaped crane girders among the figure, 2. steel column on the beam, 3. steel roof truss, 4. factory building columns upper prop, 5. capital rigid tie bar, 6. normal post distance, 7. super large column-removed spacing place.
The specific embodiment
In Fig. 1, box-shaped crane girder 1 end face at super large column-removed spacing place 7 is provided with steel column 2 on the beam hinged with it in both sides by normal post distance 6, and capital and steel roof truss 3 are hinged, and suspension column and large-scale box-shaped crane girder 1 are hinged.On the beam steel column 2 with take out post both sides factory building columns upper prop 4 and this and be listed as that intercolumniation all is provided with Force transmission partses such as capital rigid tie bar 5 on other factory buildings with normal mode.
Claims (1)
1. the method for supporting of a super large column-removed spacing factory building roof system, it is characterized in that: on large-scale box-shaped crane girder (1) end face of super large column-removed spacing place (7), increase beam on steel column (2) apart from (6) in its relevant position by normal post, (2) capital of steel column on the beam and steel roof truss (3) are hinged, and suspension column and large-scale box-shaped crane girder (1) are hinged.
