Description
Technical field
The utility model relates to a kind of folded truss.
Background technology
Truss is a kind of supporting traverse structure being formed by connecting by welding, riveted joint or bolt by rod member, truss member mainly bears axial tension or pressure, thereby can make full use of the intensity of material, comparable solid web girder is saved material in the time that span is larger, alleviate deadweight and increase rigidity.
The patent No. is that 201220218473.5 utility model patent discloses a kind of foldable brace and supports square truss, comprise and support oblique frame, upper folders, lower folders, the oblique frame of described support joins with left girder, right girder by supporting oblique frame hinge, and described upper folders joins by folders hinge and right girder and the oblique frame of support; Described lower folders joins by folders hinge and left girder and the oblique frame of support.Above-mentioned truss is in the time that stretching is square structure, support oblique frame and left and right girder, two triangular structures of upper and lower folders formation, triangular structure makes overall truss not yielding, has also alleviated the pressure of left and right girder simultaneously in the time of load-bearing, has strengthened integrally-built stability and bearing capacity.
But, two triangular structures of above-mentioned truss are by supporting oblique frame gemel connection, therefore between two triangular structures, can in use there is certain activity, the position of two triangular structures easily occurs relatively moving (while particularly utilizing truss to do supporting role), has so just affected integrally-built stability.And the length of the oblique frame of support in above-mentioned truss must approach the length of girder, when without mistake high strength, just cause certain waste of material like this, also increase overall weight simultaneously, increase burden to the work that truss is installed.
Summary of the invention
The purpose of this utility model is the folded truss that proposes a kind of stabilized structure, folding convenient and flexibly changing bulk strength.
Folded truss of the present utility model comprises folders, lower folders, supports oblique frame, the left girder being formed by connecting by upper left beam, lower-left beam, left socle and the right girder being formed by connecting by upper right beam, bottom right beam, right support, key is that described upper folders is connected with upper left beam, upper right beam by folders hinge, and lower folders is connected with lower-left beam, bottom right beam by folders hinge; The oblique frame of described support is connected with upper left beam, bottom right beam by oblique frame hinge and/or the oblique frame of described support is connected with lower-left beam, upper right beam by oblique frame hinge.
Upper folders, lower folders is inwardly simultaneously folding, can realize the gathering of truss, taking up room after drawing in is far smaller than the conventional truss size of comparable size size, and upper folders, lower folders is outwards simultaneously folding, can realize opening of truss.After truss opens, left girder and right girder are evenly shared stressed and are unloaded the effect of power, are the twices of load-bearing at ordinary times, and efficiency is largely increased, and it is being deposited, and transport aspect also can effectively utilize space.
Further, be positioned at perpendicular to the upper folders of the same plane of upper left beam, lower folders and form one group of folders, described folded truss comprises many group folders, and the quantity of the oblique frame of described support is less than or equals folders group number, and described support is tiltedly set up and is placed between two adjacent groups folders.In the time that the requirement of strength of truss is higher, can between all two adjacent groups folders, all install and support oblique frame, and in the time that the requirement of strength of truss is lower, can reduce the quantity that supports oblique frame, can not affect under the prerequisite of truss normal function like this, reduce the waste of material, alleviate overall weight simultaneously, make the easier for installation of truss.
Further, be to ensure stabilized structure, the oblique frame of described support has two at least, and one of them supports oblique frame and is connected with upper left beam, bottom right beam by oblique frame hinge, and another supports oblique frame and passes through oblique frame hinge and be connected with lower-left beam, upper right beam.In truss after opening like this, there is the oblique frame of support that incline direction is contrary, effective support strength of left and right sides direction can be provided for truss, make the trussed construction after opening more firm.
Further, described left socle and right support include vertical support frame and tilt stand, and the vertical support frame of described left socle and right support, upper folders, lower folders form rectangular configuration; Described vertical support frame, upper folders, support are tiltedly configured to triangular structure; Described vertical support frame, lower folders, support are tiltedly configured to triangular structure.Above-mentioned vertical support frame and tilt stand can make the connection between upper left beam and lower-left beam (upper right beam and bottom right beam) more firm, and vertical support frame can make the support force of left girder and right girder stronger, for truss provides larger enabling capabilities, vertical support frame, upper folders, lower folders form rectangular configuration, can ensure that trussed construction is stable, owing to having two triangles in truss, therefore truss is not easy distortion simultaneously.
Folded truss of the present utility model is simple in structure, easy to use, and can adjust as required overall support strength and weight, has good practicality and flexibility.

Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail as effect and the operating principle etc. of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part.
Embodiment 1:
As shown in Fig. 1～5, the folded truss of the present embodiment comprises folders 1, lower folders 2, supports oblique frame 3, the left girder being formed by connecting by upper left beam 4, lower-left beam 5, left socle and the right girder being formed by connecting by upper right beam 6, bottom right beam 7, right support, described upper folders 1 is connected with upper left beam 4, upper right beam 6 by folders hinge 8, and lower folders 2 is connected with lower-left beam 5, bottom right beam 7 by folders hinge 8; The oblique frame 3 of described support is connected with upper left beam 4, bottom right beam 7 by oblique frame hinge 9.
Upper folders 1, lower folders 2 is inwardly simultaneously folding, can realize the gathering of truss, taking up room after drawing in is far smaller than the conventional truss size of comparable size size, and upper folders 1, lower folders 2 is outwards simultaneously folding, can realize opening of truss.After truss opens, left girder and right girder are evenly shared stressed and are unloaded the effect of power, are the twices of load-bearing at ordinary times, and efficiency is largely increased, and it is being deposited, and transport aspect also can effectively utilize space.
