Description
Technical field
The present invention relates to the steel strand anchor installation device of a kind of pattern foundation pit supporting structure inner support system, particularly relate to steel
The connection member of twisted wire anchorage installation device.
Background technology
In Soft Soil Foundation Pit engineering, armored concrete or steel pipe support supporting construction, in order to reduce foundation ditch
Deformation, increases stability, and the most conventional method is: increase reinforced concrete fortifield village purlin size in the street, increase
The quantity of steel pipe support, reduces spacing etc..But this will be greatly increased the consumption of construction material, decrease base
Effective construction space in hole.Due to the steel support structure used at present, mainly make with single shaped steel or steel pipe
For support beam, it is formed without effectively connecting between every root type steel or steel pipe, it is impossible to work as combining structure,
So their support rigidity is relatively low, the power that can bear is relatively limited, for the foundation ditch that span is bigger,
Existing steel shotcrete support is used to be difficult to control to its deformation.These support members are owing to being much all by site operation
Require to make, there is no the size for connection of specification, it is impossible to reach to exchange between all parts and general purpose,
After causing foundation pit construction to complete, most of support members all become expendable consumed product, it is impossible to reuse.
After the most conventional pattern foundation pit supporting structure completes, without prestress application technique, or increase support member, it is impossible to
Support system improves the integral rigidity of support system further after being completed.
Summary of the invention
The present invention is directed to above-mentioned the deficiencies in the prior art, for assembled pattern foundation pit supporting structure inner support system
Fish belly sill tension structure provides the steel of a kind of stable high intensity stretch-draw to twist when tension steel strand Shi Hanzhang
Line anchorage installation device and connection member thereof, rational in infrastructure, easy accessibility, can be used repeatedly, reach
Save construction cost, the purpose of convenient construction.
The technical scheme is that and be achieved in that:
The connection member of steel strand anchor installation device, including H profile steel B, the left end face of H profile steel B is horizontal
Tangent plane is also welded with connecting plate, and connecting plate central authorities are provided with the anchorage perforate for housing anchorage, and anchorage is opened
Hole is formed around bolt hole B, and its right end face of H profile steel B is cross section and is welded with adpting flange C, H
On the left of the web of shaped steel B, depression forms the anchorage fluting for housing anchorage, wing plates on two sides before and after H profile steel B
On respectively have multiple connecting hole C.
Steel strand anchor installation device, including connection member as above.
Due to the fact that and have employed above technical scheme, open for assembled pattern foundation pit supporting structure inner support system fish belly sill
Pull-up structure provides a kind of stable high intensity tension ground tackle erecting device when stretch-draw applies stress.Steel strand wires warp
Cross fish belly sill to penetrate from threading elongated hole, then after guide channel with the tension ground tackle being arranged on anchorage substrate even
Connect, steel strand wires are pressed pulling force by tensioning equipment, after certain numerical value, anchorage is locked.In order to
Anchorage substrate side also realizes continuing to connect, and is provided with connection member, and connection member is with anchorage substrate bolt even
Connecing, be so contained in connection member by anchorage, connection member can be enclosed parts with other and is connected.The present invention
Parts are standard size parts, and easy accessibility can realize the matching requirements of plurality of specifications foundation ditch, can repeatedly weigh
Multiple utilization, reaches to save the purpose of construction cost.Use that this set standard component assembles in a specific way interior
Support system, meet prestressed in the case of, bigger construction space, convenient construction can be saved.
