The purpose of this utility model is to provide a kind of have stronger shearing resistance and bending resistance, the tunnel steelframe supporting and protection structure that stressed effect is strong.Concrete technical scheme is as follows:
A kind of tunnel steelframe supporting and protection structure, comprises at least 2 steelframes to tunnel longitudinal arrangement, and its key is: between adjacent described steelframe, connect by steel band, this steel band middle part is provided with the first anchor pole preformed hole, is equipped with the first anchor pole at this first anchor pole preformed hole.In this integer support structure, anchor pole is squeezed into rock mass by preformed hole, and anchor pole, steel band, steelframe are fastened in tunnel wall.Horizontal steel band is strained adjacent longitudinal steelframe, makes to keep balance between longitudinal steelframe, avoids crooked, strengthens the stressed effect of whole steelframe supporting and protection structure, if desired, can also lay one deck steel mesh reinforcement below steelframe.
Described steel band is rectangle, and bending two ends forms crotch, and this crotch catches on the steelframe at described steel band two ends.The crotch at steel band two ends just catches on two adjacent steelframes, makes two adjacent steelframes have more stability.
Described steelframe is i iron.I iron is conventional backing material.
Described steelframe is i iron, has the 3rd anchor pole preformed hole on described steelframe, and described the second anchor pole is simultaneously through the second anchor pole preformed hole on the 3rd anchor pole preformed hole and corresponding described steel band.Anchor pole, by steel band, through steelframe, is fixed on crag, first uses if desired nut to fix, then welds, and makes two adjacent steelframes have more stability.
Described steelframe is grid steelframe.Grid steelframe is conventional backing material.
Described steelframe is grid steelframe, and described the second anchor pole is simultaneously through the second anchor pole preformed hole on this grid steelframe and corresponding described steel band.Anchor pole, by steel band, through steelframe, is fixed on crag, first uses if desired nut to fix, then welds, and makes two adjacent steelframes have more stability.
The thick 3mm of described steel band, wide 80mm.Steel band length is determined according to bow member spacing, contrasts general indented bars and connects, and increases welding contact area, increases steelframe stability.
Described steelframe forms arched frame.In construction of tunnel, tunnel top is generally domes, so steelframe will form arch, could have supporting role to top.For adjacent 2 steelframes that form arch, the connection of steel band makes it have stability.
The utlity model has following beneficial effect:
Described tunnel steelframe supporting and protection structure utilizes steel band that anchor pole, longitudinal steelframe are connected into entirety, make the supporting power of all anchor poles be reasonably assigned to longitudinal steelframe and horizontal steel band, further be assigned to equably the surface of tunnel surrounding by steel mesh reinforcement, improve the resistance to overturning in tunnel.The crotch at horizontal steel band two ends is strained adjacent longitudinal steelframe, makes to keep balance between longitudinal steelframe, this overall structure is through stressed checking, stressed more remarkable aspect shearing resistance and bending resistance.
This structure is in tunnel, and the country rock construction sites such as mine are used, and have applicability widely.
