Problems solved by technology
However, the physiological bending formed during the natural growth of wood and the difference in mechanical properties between horizontal and vertical grains affect its mechanical properties to a certain extent, thus limiting its application range.
However, with the development of science and technology, the existing equipment has been able to ensure the shape accuracy of wooden rods after simple processing, but it has not promoted the further expansion of the application of wooden structures

The invention relates to a wood structure rectangular plate net rack which comprises multiple upper chords, multiple lower chords, multiple diagonal web members, multiple wood rod connecting pieces, multiple bolt ball joints, multiple slide hinge support seats and multiple fixed hinge support seats, wherein two ends of each upper chord, lower chord and diagonal web member are provided with a woodrod connecting piece respectively; the upper chords, the lower chords and the diagonal web members with the wood rod connecting pieces are connected together through bolt ball joints to form the mainbody of a rectangular plate net rack in traditional shape; the upper ends of the fixed hinge support seats are spaced on the upper chord bolt ball joints on one side of the main body of the net rack;the upper ends of the slide hinge support seats are spaced on the upper chord bolt ball joints on the other three sides of the main body of the net rack. The wood structure rectangular plate net rackprovided by the invention has the advantages of good shock resistance, high security, good environmental protection and good economical efficiency, and is convenient to construct and the like.
Description
technical field [0001] The invention belongs to the technical field of building structures, in particular to a large-span wooden structure rectangular flat grid. Background technique [0002] With the development of large-span space structures, grid structures have been widely used, such as airport terminals, exhibition centers, toll stations, large-span coal sheds and other buildings, all of which have application examples of grid structures. The grid structure has reasonable force, strong rigidity, and light weight. It can give full play to the tensile and compressive properties of the material, reduce the adverse effects of bending moment and shear force on the material, and the shape is changeable, and the grid size can be adjusted according to the requirements of the building. , to meet different usage needs. At present, the material selection of this structure is mainly steel, and the examples or researches of other materials used in grid structures have not been repo...
