Abstract
The utility model discloses a foldable diagonal member supporting square truss, which comprises a support inclined frame, upper folders and lower folders, wherein the support inclined frame is connected with a left main beam and a right main beam through support inclined frame hinges; the upper folders are connected with the right main beam and the support inclined frame through folder hinges; the lower folders are connected with the left main beam and the support inclined frame through the folder hinges; the support inclined frame and the left main beam, the upper folders and the right main beam and the lower folders form two stable equipotent triangular structures and form a linkage device capable of realizing quick folding; and the support inclined frame is mounted on the inner side of the upper part of the left main beam and the inner side of the lower part of the right main beam through the support inclined frame hinges. The foldable diagonal member supporting square truss solves the problems of unstable internal structure, small bearing capacity, non-folding property, large occupied area and the like of the traditional square or triangular truss, and is novel in design and more practical.
Description
Technical field
The utility model relates to a kind of truss, relates in particular to a kind of foldable brace and supports square truss, belongs to performing art engineering multifunctional equipment technical field.
Background technology
Be used at present the performing art engineering structures (TRUSS: truss) truss all is fixed square or triangular structure, square truss inside do not have brace to support stressed easy distortion and load-bearing limited, in storage and the performance transportation of flowing, take up room large, increase storage and cost of transportation, for solving this phenomenon, the utility model changes the traditional square Truss Design into collapsible, and increases the oblique frame robust structure of support and increase weight capacity in inside.
The utility model content
In order to solve the existing weak point of above-mentioned technology, the utility model discloses a kind of foldable brace and support square truss.
In order to solve above technical problem, the technical solution adopted in the utility model is: a kind of foldable brace supports square truss, comprises supporting oblique frame, upper folders, lower folders, supports oblique frame and joins with left girder, right girder by supporting oblique frame hinge; Upper folders by folders hinge and right girder be connected oblique frame and be connected; Lower folders by folders hinge and left girder be connected oblique frame and be connected.
Support the triangular structures of oblique frame and left girder, upper folders and right girder, two firm equities of lower folders composition; Support oblique frame and be installed on left girder upper inner and right girder lower inside by supporting oblique frame hinge; Upper folders, lower folders, left girder, right girder and support oblique frame and jointly form the linkage that to realize fast folding.
The utility model solved traditional square or triangular truss internal construction built on the sand, bearing capacity is little, not collapsible, the problem such as large that takes up room, its modern design, more practical.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is stretching structure schematic diagram of the present utility model.
Fig. 2 is foldable structure schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the utility model mainly comprises left girder 1, right girder 2, the oblique frame 3 of support, upper folders 4, lower folders 5, supports oblique frame hinge 6 and folders hinge 7.Support oblique frame 3 and be installed on left girder 1 upper inner and right girder 2 lower inside by supporting oblique frame hinge 6, upper folders 4 by folders hinge 7 and right girder 2 be connected oblique frame 3 and be connected, lower folders 5 passes through folders hinge 7 and left girder 1 and is connected oblique frame 3 and is connected.
Support the triangular structures of oblique frame and left girder, upper folders and right girder, two firm equities of lower folders composition; Support oblique frame and be installed on left girder upper inner and right girder lower inside by supporting oblique frame hinge; Upper folders, lower folders, left girder, right girder and support oblique frame and jointly form the linkage that to realize fast folding.
As shown in Figure 1, the utility model stretches when being square structure, support oblique frame 3 with left and right sides girder, folders forms two triangular structures up and down, triangular structure makes whole truss not yielding, when load-bearing, also alleviate simultaneously left and right sides girder part pressure, strengthen integrally-built stability and bearing capacity.The utility model makes by folders knot that can be undone by a pull up and down simultaneously that folders is crooked to form interlock folding (as shown in Figure 2) with supporting oblique frame when folding, folding after take up space when stretching 45%, for storage and transport and bring very big facility.
Above-mentioned embodiment is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in the technical solution of the utility model scope, remodeling, interpolation or replacement also all belong to protection domain of the present utility model.
