Description

Technical Field

[0001] The utility model relates to an assembled span-added staggered truss structure for a southern teaching building. Background Art

[0002] The steel structure staggered truss system is obviously superior to ordinary steel structure in structure. It is a structural system with high efficiency, economical and practical, and flexible spatial layout. It is widely used in various high-rise residential buildings, office buildings, large banquet halls and other buildings. The steel structure staggered truss system consists of trusses, beams, columns and plates. The height of the truss is the same as the floor height, and the span is the same as the width of the building. It can make the force under lateral load similar to that of the frame-shear structure. Therefore, the rigidity and strength of the structure are good. Under the vertical load and horizontal load, the bending moment in the column is small, and it mainly bears axial force.

[0003] The current fertility peak is fluctuating significantly and decreasing day by day. In the future, primary and secondary schools will be the first to be affected. More and more teaching buildings are facing social problems such as scale reduction and functional replacement. However, building industrialization can effectively reduce energy consumption, reduce dependence on natural resources, and reduce the generation of construction waste, which is consistent with the requirements of sustainable development of primary and secondary school buildings.

[0004] The Chinese utility model patent application number is 201822000689.4, and the patent name is a patent for an assembled steel structure staggered truss system, which includes multiple steel structure trusses, multiple steel structure frame columns, multiple steel structure frame beams and multiple assembled integral composite floor slabs. The upper end of the steel structure truss is welded with an upper chord, the lower part of the steel structure truss is welded with a lower chord, and the lower ends of the steel structure truss extend out of the bottom end surface of the lower chord. A truss hanging support beam is welded on both sides of the lower end of the steel structure truss; by setting a truss hanging support beam under the lower chord of each truss, the original tension between the floor slab and the lower chord of the truss is transferred to the pressure between the floor slab and the support beam, so as to avoid cracking of the floor slab concrete due to tension exceeding the tensile strength. It can be seen from the attached drawings that the staggered truss system is relatively square as a whole, which is suitable for the situation where the base boundary is relatively square. When the plane layout of the building is limited, the base boundary is irregular, and lighting must be guaranteed, the above-mentioned staggered truss system is not applicable. Utility Model Content

Moreover, the sawtooth shape can also improve the monotonous and flat appearance in the existing system, so as to achieve the effect of beautifying the appearance of the building.

[0054] At the same time, by setting up the span module 400, the north and south sides of the building are given a full-height space that breaks through the floor slab limit, which increases the spatial expression and breaks the homogenized space of the staggered truss system. Moreover, in the stage of declining birth rate, the overall society is turning into an aging society, and the demand for elderly care is growing. The staggered truss structure can also be replaced by a community day care elderly care center. Alternatively, it can also be replaced by other public buildings such as hospitals.
