Description
Technical field
The present invention relates to tunnel (tunnel) structural support technical field, the metal branch of soft rock tunnel is more particularly to can be applied to
The contractibility attachment structure of frame supporting construction.
Background technology
The support of existing soft rock tunnel (tunnel) is generally divided into not collapsible timbering and collapsible timbering.Not contractibility branch
Frame is usually rigid flange beam stand, because it can not contract, deformability is limited, can so cause a batch of rigid I-shapeds
Steel bracket is incompatible with the large deformation of country rock, it is impossible to be widely used.Contractibility support, its structure is typically with
The end of the two U-shaped steel of section is mutually overlapped, and the form being fixed to the position of mutual overlap joint with U-shaped card.
The frictional force that collapsible timbering relies primarily on two shaped steel of U-shaped card offer supports roadway surrounding rock.Work as shoulder bed effects
In the outer load on support along shaped steel component more than two shaped steel lap segments frictional resistance when, shaped steel slide, make support section contract
It is small, but the collapsible timbering of this structure, and due to there is overlapping section in the junction of two shaped steel, therefore junction section is present
Certain bias, easily causes the problem of junction unstability.
