Abstract
The utility model relates to superimposed trailer main beam structure, reduces girder weight, be specially a kind of superimposed trailer girder section structure for increasing girder intensity.Solve the technical matters of current superimposed trailer girder undercapacity, a kind of superimposed trailer girder section structure is provided.A kind of superimposed trailer girder section structure, the web comprising horizontally disposed upper lower wing plate and be vertically connected between lower wing plate; Form horizontal segment after the bending of described web upper horizontal and be connected to the below of upper flange by the end face of horizontal segment.The utility model actv. adds the intensity of web top and upper flange contact position, after upper flange thickness reduces, can ensure that girder also has certain intensity, be equivalent to the weight alleviating whole girder.
Description
Technical field
The utility model relates to superimposed trailer main beam structure, reduces girder weight, be specially a kind of superimposed trailer girder section structure for increasing girder intensity.
Background technology
Along with the high speed development of national economy, the proportion of superimposed trailer long-distance transport is increasing, but traditional heavy semi-trailer cannot meet the requirement of national weight metering charging, the lightweight of market an urgent demand superimposed trailer.Although numerous superimposed trailer manufacturing enterprise takes various mode to reduce deadweight, achieve certain effect, superimposed trailer main beam structure does not have greatly improved, be the thickness of reduction sheet material simply, sacrifice the load-carrying capacity of girder.For this reason, need to design a kind of novel girder section structure, the lightweight demand in market can be met, the intensity that girder is own can be ensured again.
The web that traditional main beam structure mainly comprises wing plate setting up and down and is vertically connected between lower wing plate; Its median ventral plate is directly connected with upper flange by top, and connection area is little, insufficient strength.
Summary of the invention
The utility model is the technical matters solving current superimposed trailer girder undercapacity, provides a kind of superimposed trailer girder section structure.
The utility model adopts following technical scheme to realize: a kind of superimposed trailer girder section structure, the web comprising horizontally disposed upper lower wing plate and be vertically connected between lower wing plate; Form horizontal segment after the bending of described web upper horizontal and be connected to the below of upper flange by the end face of horizontal segment.
The utility model, when ensureing the intensity of superimposed trailer girder, reduces deadweight further.For achieving the above object, the utility model to take on girder web plate after Edge Bend with upper flange welded structure, strengthen the support to wing plate, whole girder intensity increased; Even if when upper flange thickness reduces, can also ensure that girder has certain intensity.
Further, the front end of the horizontal segment formed after the bending of described web upper horizontal is bent to form vertical section downwards again.
After adopting the utility model, girder can also reduce deadweight within the specific limits, improves cargo capacity, further increases the economic benefit in use procedure.
The utility model actv. adds the intensity of web top and upper flange contact position, after upper flange thickness reduces, still can ensure that girder also has certain intensity, be equivalent to the weight alleviating whole girder.

Detailed description of the invention
A kind of superimposed trailer girder section structure, the web 3 comprising horizontally disposed upper lower wing plate and be vertically connected between lower wing plate; It is characterized in that, form horizontal segment 4 after the bending of described web 3 upper horizontal and be connected to the below of upper flange 1 by the end face of horizontal segment 4.
The front end of the horizontal segment 4 formed after the bending of described web upper horizontal is bent to form vertical section 5 downwards.
Horizontal segment 4 and vertical section 5 effectively can support upper flange 1, and support zone intensity is improved.
