Abstract
The utility model discloses a ribbed trapezoid steel strip which comprises a trapezoid section face, a circular-truncated-cone-shaped anchor rod tray base, anchor rod round holes, a vertical rib, transverse ribs and an inclined rib, wherein the circular-truncated-cone-shaped anchor rod tray base is formed on the narrow bottom face of the trapezoid section face, the anchor rod round holes are formed in the circular-truncated-cone-shaped anchor rod tray base and the trapezoid section face in a penetrating mode, the vertical rib is formed on the bottom face and extends in the length direction of the trapezoid section face, the number of the transverse ribs is more than one, the transverse ribs are perpendicular to the vertical rib and formed on the bottom face at a preset interval, and the inclined rib is formed on the circumferential face of the circular-truncated-cone-shaped anchor rod tray base. According to the ribbed trapezoid steel strip, trapezoid section face and the circular-truncated-cone-shaped anchor rod tray base are reinforced through the transverse ribs and the vertical rib on the section face and the inclined rib on the tray base, the trapezoid section face facilitates uniform disperse of action force to a surrounding rock, and the ribs enhance the supporting capacity of the steel strip. The ribbed trapezoid steel strip is suitable for anchor rod cable support on high-stress strong supporting conditions, bearing force of the steel strip can be effectively improved, and the overall supporting capacity is enhanced.
Description
Technical field
The utility model relates to Anchor in Geotechnical Engineering rope reinforcing technique field, especially relates to the trapezoidal steel band of formula with ribbing.
Background technology
Reinforce unstable rock-soil layer country rock for anchor pole rope, mainly use anchor pole rope to add steel band supporting, wherein, use steel band to mainly contain tubular, U-shaped or W-shaped steel band, anchor pole, through pallet and steel band, is arranged at steel band between country rock and pallet, plays good holder and pushes away effect.
But, used tubular, U-shaped or W-shaped steel band stressed concentrated in the past, be unfavorable for that active force spreads in country rock body, under high stress, easily there is stress and concentrate and destroy; In addition, tubular, U-shaped or W-shaped steel band wall were plane in the past, bore shoulder bed effects power little.
Utility model content
The problem existing for prior art, order of the present utility model is to provide one to bear that shoulder bed effects power is large, the trapezoidal steel band of the uniform formula with ribbing of transmission power.
The trapezoidal steel band of one of the present utility model formula with ribbing, comprising:
Trapezoid cross section band;
Truncated cone-shaped anchor rod pallet board base, is formed on the narrower bottom surface of the width of described trapezoid cross section band;
Anchor pole circular port, runs through and is opened on described truncated cone-shaped anchor rod pallet board base and trapezoid cross section band;
Vertical rib, is formed on described bottom surface, and extends along described trapezoid cross section strip length direction;
Cross rib, this cross rib one or more, perpendicular and interval preset space length is formed on described bottom surface with described vertical rib;
Diagonal rib, is formed on the periphery of described truncated cone-shaped anchor rod pallet board base.
The utility model utilizes diagonal rib on cross rib on the band of cross section, vertical rib and basetray to strengthen disposal to trapezoid cross section band and truncated cone-shaped anchor rod pallet board base, trapezoid cross section band is conducive to active force and evenly spreads in country rock body, and various ribs are conducive to strengthen steel band support bearing ability.The trapezoidal steel band of formula with ribbing is applicable to anchor pole rope supporting under heavily stressed strong supporting condition, can effectively improve the bearing capacity of steel band, increases integrated support ability.
The trapezoidal steel band of formula with ribbing evenly spreads anchor rod pallet board active force by trapezoidal wearing in country rock body, is difficult for causing pallet and steel band stressed concentrated; Trapezoidal steel band and truncated cone-shaped basetray all arrange rib, can effectively improve the bearing capacity of steel band, increase integrated support ability, are conducive to anchor pole rope prop stable.

Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
As shown in Figure 1, 2, the utility model comprises: trapezoid cross section band 2, truncated cone-shaped anchor rod pallet board base 5, anchor pole circular port 1, vertical rib 6, cross rib 3 and diagonal rib 4.Truncated cone-shaped anchor rod pallet board base 5 is formed on the narrower bottom surface of the width of trapezoid cross section band 2.Anchor pole circular port 1 runs through and is opened on truncated cone-shaped anchor rod pallet board base 5 and trapezoid cross section band 2.Vertical rib 6 is formed on the bottom surface of trapezoid cross section band 2, and states the length direction extension of trapezoid cross section band 2.Cross rib 3 is some, and perpendicular and interval preset space length is formed on the bottom surface of trapezoid cross section band 2 with vertical rib 6.Diagonal rib 4 is formed on the periphery of truncated cone-shaped anchor rod pallet board base 5.
Cross rib 3, vertical rib 6 and diagonal rib 4 are for the mode by compacting is at the impression being formed on the bottom surface of trapezoid cross section band 2 and the periphery of truncated cone-shaped anchor rod pallet board base 5.
Like this, the utility model just utilizes diagonal rib 4 on cross rib 3 on the band of cross section, vertical rib 6 and basetray to strengthen disposal to trapezoid cross section band 2 and truncated cone-shaped anchor rod pallet board base 5, trapezoid cross section band 2 is conducive to active force and evenly spreads in country rock body, and various ribs are conducive to strengthen steel band support bearing ability.The trapezoidal steel band of formula with ribbing is applicable to anchor pole rope supporting under heavily stressed strong supporting condition, can effectively improve the bearing capacity of steel band, increases integrated support ability.
The trapezoidal steel band of formula with ribbing by trapezoidal wear 2 by anchor rod pallet board active force to evenly diffusion in country rock body, be difficult for causing that pallet and steel band are stressed concentrates; Trapezoidal steel band and truncated cone-shaped basetray all arrange rib, can effectively improve the bearing capacity of steel band, increase integrated support ability, are conducive to anchor pole rope prop stable.
The trapezoidal steel band fitting operation of the utility model formula with ribbing is simple, construction is fast, and it is more even that the stressed effect of panel with ribbing is large, power is transmitted in trapezoid cross section.
