Description
Technical field
The utility model belongs to building engineering field, is specifically related to a kind of novel steel-concrete composite open-web beam system.
Background technology
In the total system forming on superstructure, beam, post and basis, common floor generally can only be accomplished 6 meters of left and right, in the time that the span of floor is greater than 6 meters, stressed crossbeam generally all can be set in the middle of floor, in the time that span is larger, must make deck-molding increase for increasing rigidity, thereby reduce head room. For reducing the amount of deflection of floor, tend to thicken floor simultaneously, heavy floor, concrete and amount of reinforcement are larger, and structural weight per square meter strengthens, very uneconomical.
Domestic a lot of scholar expert improves traditional beam-and-slab floor system for this reason, Rc Open-web Sandwich Plates superstructure is after the thrifty team of nineteen ninety-five mark of Guizhou University studies successfully, successively be applied in the multinomial engineerings such as International Furniture city, From Anshun of Guizhou city, Guizhou Aluminum Factory warm water natatorium, international shopping square, South Sinkiang, and passed through " Rc Open-web Sandwich Plates building cover structure technical regulation " in 2005. This superstructure is made up of face vener, upper rib, lower rib and shear connector, because the splendid economic and technical norms of its good mechanical property obtain the extensive favorable comment of industry, but this structural system also exists rib under indivedual concrete can not effectively control crack, site operation template requirement is large, the shortcoming that efficiency of construction is low. Given this, the derivative steel-concrete combined hollow sandwich plate floor system that is welded to connect that developed again, this system essential structure is made up of rib, concrete shear connector and concrete slab on the lower rib of U-shaped steel plate combination, concrete, and U-shaped steel plate is by being welded to connect. Be applied in the process of Hong Kong main force electrical equipment (Kweiyang) Co., Ltd Industrial Plant in this system, occurred again the problem that welding deformation is larger. Tracing it to its cause is to weld shrinkage stress the every grid of U-shaped steel plate is upwards swelled, thereby causes larger upwards welding deformation, makes to combine the comparatively difficulty that is stitched together of lower rib U-shaped steel plate grid, cannot ensure grid Founder, straight. Accordingly, also there is the problem that Site Welding workload is larger in this system.
For the consideration that alleviates floor construction deadweight, improves efficiency of construction, reduces or avoid possible node weld to be out of shape, need to design a kind of pin-connected panel composite open-web beam system, in giving full play to material mechanical performance, accomplish to assemble simple and convenient, the target that molded integral is good, reaches the actual requirement of upgrading synergy.
