Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in structure, easy for installation, high split type steel case beam of making precision.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of split type steel case beam, comprise top box beam and nowel beam, described top box beam is equipped with nowel beam the interface matching, described top box beam comprises top board, the first web floor and the first dividing plate, nowel beam comprises the second web floor, second partition, gusset and base plate, described the first web floor, the second web rib plate level arranges, described the first dividing plate, second partition is respectively perpendicular to top board and base plate, described the first dividing plate coordinates with second partition, described the first dividing plate is provided with the groove lower than interface place plane, described second partition is provided with the projection of protruding interface place plane, and the groove of the first dividing plate is consistent lower than the distance of the distance of interface place plane and the projection of second partition protrusion interface place plane.
Preferably, described the first dividing plate and second partition are equipped with more than two, and the both sides of described the first dividing plate and second partition all arrange floor, between two adjacent the first dividing plates, between second partition, be provided with level intersect horizontal reinforcing plate.
Preferably, the vertical side of described top box beam, nowel beam is respectively equipped with the vertical gusset plate of right-angled intersection.
The beneficial effect that adopts technique scheme to produce is: by steel case beam is carried out to split-type design, make its weight and highly meet the requirement of transporting, by the horizontal reinforcing plate of inner chamber and the vertical gusset plate of side that are arranged on top box beam and nowel beam, it is reinforced simultaneously, guarantee in transportation, hoisting process indeformable, after being transported to building site, again top box beam and nowel beam are carried out to integral solder, guarantee that like this steel case beam meets in correlation technique requirement situation in making, be conducive to meet the needs of transportation.Steel box beam Welding is complete to be removed horizontal reinforcing plate and vertical gusset plate again, makes it to reach the requirement of engineering.Just solve thus the technical problem that Large Steel case beam segmentation transportation and coupling are made, the utlity model has simple in structure, easy for installation, high, the safe and reliable advantage of making precision, can under the prerequisite of making quality that guarantees Large Steel case beam, improve efficiency of construction.
