Abstract
The utility model provides a new -type girder belongs to girder technical field for building, can not be satisfied with current market requirements's light weight design to present girder, and pure dig the hole and not carry out periphery tensile on the girder, and the beam strength problem that can reduce because of the trompil is improved the structure of girder greatly. Its structure includes fixed connection's girder riser and girder support piece, the girder riser has a plurality of circular convex surfaces with girder support piece's the outside punching press drawing of ATTACH SURFACES, and photogenic the running from opposite directions of every circular convex surface is equipped with a through -hole, the through -hole is a round hole and four the irregularly -shaped holes that semicircle orifices intercommunication formed of equipartition outside the round hole, plays the bending strength of reinforcing girder and the effect of resistance to torsion when lightening the weight of girder. The utility model is used for the building field plays the effect of support.
Description
Technical field
The utility model relates to crossbeam technical field for building, specifically a kind of new-type crossbeam.
Background technology
Existing crossbeam can not be satisfied with the light-weight design of Vehicles Collected from Market requirement, and simple borehole on crossbeam and do not carry out circumferential extensional, large beam strength can reduce because of perforate, and then affects the actual use of crossbeam.
Summary of the invention
Technical assignment of the present utility model solves the deficiencies in the prior art, provides a kind of new-type crossbeam.
The utility model solves the technical scheme that its technical problem adopts:
A kind of new-type crossbeam, comprise the crossbeam riser and crossbeam support member that are fixedly connected with, in the use of reality, in order to alleviate the weight of crossbeam, and strengthen flexural strength and the resistance to torsion of crossbeam, the outside punching stretch of connecting surface of described crossbeam riser and crossbeam support member has multiple circular convex, and each circular convex offers relatively a through hole.
On this basis, the through hole selected is irregularly-shaped hole, and irregularly-shaped hole, compared to common through hole, effectively can discharge the stress because perforate causes, and irregularly-shaped hole is opened in the circular convex of punching stretch, and after ensure that punching, large beam strength does not subtract.
Prioritizing selection, described irregularly-shaped hole is that a circular hole is communicated with four semicircle orifices be distributed on outside circular hole and forms.
The multiple through hole of prioritizing selection is divided into two groups, is staggered up and down on crossbeam riser.
The beneficial effect that a kind of new-type crossbeam of the present utility model is compared with prior art produced is:
The utility model is reasonable in design, structure is simple, by the multiple circular convex of the outside punching stretch of connecting surface at crossbeam riser and crossbeam support member, and in each circular convex, relatively offers a through hole, to alleviate the weight of crossbeam, strengthen flexural strength and the resistance to torsion of crossbeam.
Accompanying drawing explanation
Accompanying drawing 1 is partial structurtes schematic diagram of the present utility model;
Accompanying drawing 2 is the partial enlargement structural front view in the utility model, crossbeam riser being offered irregularly-shaped hole;
Accompanying drawing 3 is A-A direction view of Fig. 2.
In figure, 1, crossbeam riser, 2, crossbeam support member, 3, circular convex, 4, irregularly-shaped hole.
Detailed description of the invention
Below in conjunction with accompanying drawing 1-3, the new-type crossbeam of one of the present utility model is described in detail below.
As shown in drawings, the new-type crossbeam of one of the present utility model, its structure comprises the crossbeam riser and crossbeam support member that are fixedly connected with, in the use of reality, in order to alleviate the weight of crossbeam, and strengthening flexural strength and the resistance to torsion of crossbeam, the outside punching stretch of connecting surface of described crossbeam riser and crossbeam support member has multiple circular convex, and each circular convex offers relatively a through hole.
On this basis, the through hole selected is irregularly-shaped hole, and irregularly-shaped hole, compared to common through hole, effectively can discharge the stress because perforate causes, and irregularly-shaped hole is opened in the circular convex of punching stretch, and after ensure that punching, large beam strength does not subtract.
Prioritizing selection, described irregularly-shaped hole is that a circular hole is communicated with four semicircle orifices be distributed on outside circular hole and forms.
The multiple through hole of prioritizing selection is divided into two groups, is staggered up and down on crossbeam riser.
In sum, content of the present utility model is not limited in the above-described embodiment, and those skilled in the art can propose other embodiment within guiding theory of the present utility model, but these embodiments are all included within scope of the present utility model.
Claims (4)
1. a new-type crossbeam, comprises the crossbeam riser and crossbeam support member that are fixedly connected with, it is characterized in that, the outside punching stretch of connecting surface of described crossbeam riser and crossbeam support member has multiple circular convex, and each circular convex offers relatively a through hole.
