Embodiment Construction
[0035] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0036] see figure 1 , 2 In this embodiment, the cantilever construction dismountable triangular hanging basket load-bearing main truss includes a main beam 1 composed of double I-beams, a hinged adjustable base 2, a column 3 assembled with channel steel, a plate-type connection column head 4, and a The front and rear oblique tie rods 5, 6, and 7 formed by pulling 16Mn steel belts (the single oblique tie rod on each side is composed of 2 No. 5 steel belts, 1 No. 6 steel belt and 2 No. 7 steel belts, among which, The specification of No. 6 steel strip is generally 200mm×21mm, the specification of No. 5 and No. 7 steel strips is generally 200mm×12mm), and No. 45 steel pins 8, 9 and 10 are subjected to shear and pressure.
[0037] Such as Figure 3a , 3b As shown, the main girder 1 includes two I-beams 11 arranged in parallel. can change t...

The invention discloses a cantilever construction detachable triangle hanging basket load-bearing primary truss which comprises a girder, an adjustable base, a stand column, a plate-type connecting chapiter and diagonal members. The adjustable base is formed by connecting upper and lower parts through a first hinge pin; the lower part of the adjustable base is connected with the middle part of the girder by intermittent welding; the upper part of the adjustable base is fixedly connected with the lower end of the upright; the upper end of the stand column is connected with the plate-type connecting chapiter by a bolt; both sides of the plate-type connecting chapiter are respectively connected with the diagonal members by second hinge pins; the diagonal members at both sides are symmetrically arranged; the lower ends of the diagonal members are connected to one end of the girder by third hinge pins. The cantilever construction detachable triangle hanging basket load-bearing primary truss disclosed by the invention is formed by utilizing the characteristics of shape steels to carry out machining manufacturing and assembling; not only can the dead weight of a hanging basket be reduced, but also a balance weight is not required; meanwhile, the cantilever construction detachable triangle hanging basket load-bearing primary truss is provided with a small number of components and is convenient to install and transport; the use effect of the hanging basket is ensured; meanwhile, the utilization rate of the components is greatly improved and cost of manufacturing, transportation and the like of equipment is also reduced.
Description
technical field [0001] The invention belongs to the technical field of bridge construction load-bearing structures, and in particular relates to a load-bearing main truss of a cantilever construction dismountable triangular hanging basket. Background technique [0002] The hanging basket for cantilever construction was originally a parallel truss type. With the optimization of the structure design of the hanging basket and the development of the material industry, the form of the hanging basket is diversified, the structure is getting lighter and the force is more and more reasonable. Hanging baskets are mainly divided into parallel truss hanging baskets, bowstring hanging baskets, cable-stayed hanging baskets, rhombus hanging baskets, and triangular hanging baskets. [0003] Parallel truss-type hanging baskets are generally not used due to their heavy weight. Due to the heavy weight of the triangular composite beam hanging basket, there are certain limitations in applicati...
