Abstract
The utility model discloses a trussed beam superposition structure, comprising a bottom beam, a top beam and a trussed beam. The trussed beam assembly is a triangular structure. Two corners at the lower end of the trussed beam assembly are respectively fixed to the bottom beam. The upper end of the trussed beam assembly is locked to the top beam. The trussed beam assembly comprises two lower trussed beam assemblies and one upper trussed beam assembly, which are both triangular structures. The top end of the upper trussed beam assembly is fixed to the top beam. Two corners at the lower end of the upper trussed beam assembly are respectively fixed to the top beams of the two lower trussed beam assemblies through flanges. The bottom ends of the two lower trussed beam assemblies are respectively fixed to the bottom beam. The trussed beam superposition structure is advantageous in that an integral trussed beam is dispersed into a combination structure, and thereby the weight of a single assembly is reduced; transport and usage are convenient.
Description
Technical field
The utility model belongs to beam construction equipment field, is specifically related to the trusses iterative structure of section assembling bridge formation machine.
Background technology
Trusses has very important effect in the use of section assembling bridge formation machine, the trusses of section assembling bridge formation machine is to adopt whole triangular structure at present, and this structure is heavy, has caused trouble and inconvenience to transportation.
The utility model content
The purpose of the utility model provides a kind of trusses iterative structure, has overcome the above-mentioned deficiency of prior art, and all-in-one-piece trusses is dispersed into combining structure, has reduced the weight of single component, transportation, easy to use.
In order to reach above-mentioned purpose of design, the technical scheme that the utility model adopts is following:
A kind of trusses iterative structure; Comprise bottom girder, back timber and trusses assembly, said trusses assembly is a triangular structure, on the bottom girder that two corners, lower end of trusses assembly are separately fixed at; The upper end locking of said trusses assembly is on back timber; Said trusses assembly comprises two bottom side rail assemblies and a roof side rail assembly, and said two bottom side rail assemblies, roof side rail assembly are triangular structure, and the top of roof side rail assembly is fixed on the back timber; Two corners, lower end of roof side rail assembly connect the top of two bottom side rail assemblies respectively through flange, the bottom of two bottom side rail assemblies is separately fixed on the bottom girder.
Preferably, the side frames of said roof side rail assembly is oppositely arranged with the bogie side frame in the outside of two bottom side rail assemblies respectively.
More preferably; The bogie side frame center in the left side of the bogie side frame center in the left side of said roof side rail assembly and the bottom side rail assembly in left side point-blank, the bogie side frame center on the right side of the bogie side frame center on the right side of said roof side rail assembly and the bottom side rail assembly on right side is point-blank.
The beneficial effect of the described trusses iterative structure of the utility model is: all-in-one-piece trusses is dispersed into combining structure, has reduced the weight of single component, transportation, easy to use reduces manufacturing cost.
Description of drawings
Fig. 1 is the sketch map of the described trusses iterative structure of the utility model embodiment;
Fig. 2 is the sectional view of the described trusses iterative structure of the utility model embodiment.
In the accompanying drawing: 1, bottom girder; 2, back timber; 3, trusses assembly; 4, bottom side rail assembly; 5, roof side rail assembly; 6, flange; 7, bogie side frame.
The specific embodiment
Below in conjunction with accompanying drawing the optimum implementation of the utility model is done further detailed description.
As illustrated in fig. 1 and 2; The described trusses iterative structure of the utility model embodiment comprises bottom girder 1, back timber 2 and trusses assembly 3, and said trusses assembly 3 is a triangular structure; On the bottom girder 1 that two corners, lower end of trusses assembly 3 are separately fixed at, said trusses assembly 3 upper ends lock on back timber 2.
Said trusses assembly 3 comprises two bottom side rail assemblies 4 and a roof side rail assembly 5; Said two bottom side rail assemblies 4, roof side rail assembly 5 are triangular structure; The top of roof side rail assembly 5 is fixed on the back timber 2, and two corners, lower end of roof side rail assembly 5 connect the top of two bottom side rail assemblies 4 respectively through flange 6, and the bottom of two bottom side rail assemblies 4 is separately fixed on the bottom girder 1; Bogie side frame 7 centers in the left side of bogie side frame 7 centers in the left side of said roof side rail assembly 5 and the bottom side rail assembly 4 in left side point-blank; Bogie side frame 7 centers on the right side of bogie side frame 7 centers on the right side of said roof side rail assembly 5 and the bottom side rail assembly 4 on right side point-blank, said structure makes trusses assembly 3 be divided into the form of structure of two laminated, and the bogie side frame 7 of a bottom side rail assembly 4 and a roof side rail assembly 5 is connected to become a bar relatively; Promptly form a big triangular-section with three little triangles; Under the prerequisite of stiffness that guarantees structure and resistance to overturning, not only reduce the weight of trusses, reduced the height of trusses simultaneously; Convenient transportation reduces manufacturing cost.
This specific embodiment is the preferred embodiment of the utility model, can not limit the utility model, and concrete each item rights protection scope is defined by the claims.
