As further optimization of the present utility model, vierendeel truss system described in the utility model includes some first vierendeel truss systems and some second vierendeel truss systems, described first vierendeel truss system is arranged in a frame unit by a diagonal web member diagonal angle, and the diagonal web member setting direction in adjacent two the first vierendeel truss systems forms v-shaped structure relatively; The diagonal web member that described second vierendeel truss system is in the shape of the letter V downwards by pair of openings is arranged in a frame unit.
As further optimization of the present utility model, the first vierendeel truss symmetry system having symmetry described in the utility model is arranged on the second vierendeel truss system both sides.
As further optimization of the present utility model, the second vierendeel truss system described in the utility model also includes chord member, and described chord member is arranged on the axis of symmetry place of a pair V-shaped diagonal web member.
As further optimization of the present utility model, this utility model also includes steel bar truss floor, and described steel bar truss floor runs through with two frame unit height for spacing interval and is arranged on intercolumniation beam.
As further optimization of the present utility model, steel bar truss floor described in the utility model runs through and is arranged on top framework, frame column top and top intercolumniation beam.
Beneficial effect: this utility model is compared with prior art, have the advantage that the vierendeel truss that this utility model is made is up-small and down-big structure, its appearance looks elegant, and adopt steel bar truss floor can effectively control the pulling force of back timber, and can effectively improve vierendeel truss rigidity, it is ensured that truss stress, deformation meet requirement.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
1 frame post, 11 batter posts, 2 intercolumniation beams, 3 vierendeel truss systems, 31 first vierendeel truss systems, 32 second vierendeel truss systems, 321 chord members, 4 diagonal web members, 5--steel bar truss floor.
