Description
Technical field
The utility model belongs to foundation pit or slope excavating impermanency support engineering field, and in particular to a kind of prestressed anchor
Rope is from anchor device.
Background technology
In foundation pit or the construction of slope excavating impermanency support engineering, stake-anchor support system is widely used.In general, stake
When spacing is smaller, the same height between adjacent two support pile stakes sets an anchor cable to provide enough pulling force；Stake spacing compared with
When big, with height two anchor cables need to be set to provide enough pulling force in the both sides of every support pile.The company of anchor cable and support pile
Connection device is generally made of waist rail and anchorage, specifically using rest of the waist rail as anchorage for being arranged at support pile side, is opened
After drawing anchor cable, anchorage cable anchoring power is passed to adjacent two support piles by anchorage through waist rail, with soil pressure suffered by this balance supporting stake.
Because waist rail Path of Force Transfer is clear, it has been widely used at present, common waist rail has cast-in-situ steel reinforced concrete waist rail and steel welding
Assembled two kinds of waist rail is connect, wherein cast-in-situ steel reinforced concrete waist rail rigidity is big, and small, prestressd anchor cable is deformed under anchor cable pulling force effect
Lose small, support pile displacement at pile top is controlled, the shortcomings that it is maximum is that formwork takes and needs certain concrete curing time
Anchorage cable stretching can be carried out, is had a great influence to foundation pit or side slope entirety excavation construction speed；The assembled waist rail installation of shaped steel welding is applied
Work speed is relatively fast, but the drawback is that rigidity is relatively small, torsional deformation is also easy to produce under anchor cable pulling force effect, and anchor cable in advance should
Power loss is larger, is also unfavorable for the control of support pile displacement at pile top.In addition, generally masterpiece is concentrated by multiple span centres when waist rail designs
Multispan simply supported beam under is calculated, when support pile stake spacing (girder span) is larger, waist rail institute bending moment is larger, deformation compared with
Greatly, meet that the required waist rail sectional dimension of safety is also corresponding larger, and then cause the increasing of waist rail operation side, installation difficulty to carry
High, project cost increase.
Utility model content
In view of this, the utility model provides a kind of prestress anchorage cable from anchor device, of the prior art to solve
Deficiency.
The technical solution of the utility model is：A kind of prestress anchorage cable is from anchor device, including two pieces parallel with a determining deviation
Symmetrically placed shape of a saddle steel plate, is respectively arranged with the second circular aperture on four angles of the shape of a saddle steel plate, and described
Steel connecting rod is provided with two circular apertures, the both ends of the steel connecting rod are connected with two blocks of shape of a saddle steel plates respectively, the shape of a saddle
Steel plate is respectively arranged with billet against the two sides of bottom surface, and the lower surface and the side of shape of a saddle steel plate of the billet are consolidated
Even, the upper surface of the billet is provided with anchorage, and the anchorage center is aligned with the first circular aperture center of circle on billet,
The upper surface of anchorage is affixed with billet outer surface；Two diagonal cross are provided with space between the shape of a saddle steel plate
Anchor cable, one end of the anchor cable are connected after the first circular aperture on billet is pierced by with anchorage, and the other end is anchored in the soil body
Among.
Compared with prior art, a kind of prestress anchorage cable provided by the utility model is from the beneficial effect of anchor device：
1st, a kind of prestress anchorage cable provided by the utility model makes full use of the big spy of support pile pile body stiffness from anchor device
Point, anchorage force of pre-stressed anchor cable is directly acted on supporting stake body, make support pile stake spacing it is larger, need every supporting
When the both sides of stake set two anchor cables with height, without setting waist rail, Path of Force Transfer is definitely, intuitively.
2nd, the whole of the utility model is connected reliably from anchor device with support pile, avoid because waist rail deformation and caused by anchor
Rope loss of prestress, rigidity is big, can more effectively control support pile displacement at pile top.
3rd, the utility model is all process using steel, and size is smaller, is made simply, and installation is quick, and construction is completed
After can be dismantled and reused, can realize standardization, streamlined operation.
