Abstract
The utility model discloses an anchor device, which is convenient to use and does not have steel strand stress loss. The anchor device comprises a work anchor (8) and a tool anchor (10) and is characterized in that the work anchor (8) comprises an upper work anchor block (6) and a lower work anchor block (9) which are connected through screw bolts (2), a wedge-shaped clamp sheet (5) split in an axial direction is arranged in a wedge-shaped hole formed between the upper work anchor block (6) and the lower work anchor block (9), the tool anchor (10) comprises an upper tool anchor block (3) and a lower tool anchor block (11) which are connected through the screw bolts (2), and steel strand holes are arranged between the upper tool anchor block (3) and the lower tool anchor block (11). The anchor device has the advantages of simple structure, small size, light weight, low cost, high speed and safety, is easy to process and convenient to construct and can ensure that the steel strand stress is not lost in the whole operation process after the anchoring position of non-cohesive prestressing steel strands in the work state is changed, and the secondary tensioning of the steel strands is not needed.
Description
Technical field
The utility model relates to a kind of ground tackle, particularly relates to a kind of steel strand anchorage.
Background technology
Owing to reasons such as urban construction and development or the changes of building function, need reconstruct, extend existing construction work.For the concrete floor system, the roof system that adopt non-bending steel cable, superstructure partly to be removed, the high-stress state of the steel strand of remainder superstructure can not have any change, needs a kind of ground tackle and can be competent at this work.And traditional ground tackle is made up of annular anchor cup and wedge intermediate plate, and steel strand pass the anchor cup, and by the anchoring of wedge intermediate plate, because its reasons in structure, it is only applicable to the steel strand anchoring of new construction.
Summary of the invention
The purpose of this utility model provides a kind of easy to use, the break-even a kind of ground tackle of the stress of steel strand.
The utility model is to adopt following technical scheme to realize its goal of the invention, a kind of ground tackle, it comprises work anchor, moveable anchor, described work anchor comprises by bolted work anchor block, the anchor block of working down gone up, on work anchor block, work and be provided with the wedge intermediate plate of axial subdivision in the wedge hole that forms between the anchor block down; Described moveable anchor comprises by bolted instrument anchor block, the following instrument anchor block gone up, is provided with the steel strand hole between last instrument anchor block, the following instrument anchor block.
Be fastening steel strand better, the steel strand hole of going up the instrument anchor block, forming between the instrument anchor block down of the present utility model is provided with silk mouthful.
Wedge intermediate plate of the present utility model is provided with the silk mouth.
Owing to adopt technique scheme, the utility model has been realized goal of the invention preferably, it is simple in structure, little, in light weight, the easy processing of volume, with low cost, easy construction, quick, safety, can guarantee that after changing in running order un-bonded prestressed steel strand anchorage point, the stress of steel strand does not lose in the whole operation process, need not the two times tensioning of steel strand.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of ground tackle, it comprises work anchor 8, moveable anchor 10, and described work anchor 8 comprises the work of the going up anchor block 6 that connects by bolt 2, the anchor block 9 of working down, on work anchor block 6, work and be provided with the wedge intermediate plate 5 of axial subdivision in the wedge hole that forms between the anchor block 9 down; Described moveable anchor 10 comprises the last instrument anchor block 3 that connects by bolt 2, following instrument anchor block 11, is provided with the steel strand hole between last instrument anchor block 3, the following instrument anchor block 11.
Be fastening steel strand 1 better, the steel strand hole of going up instrument anchor block 3, forming between the instrument anchor block 11 down of the present utility model is provided with silk mouthfuls 4.
Wedge intermediate plate 5 of the present utility model is provided with silk mouth 4.
When the utility model uses, at first determine steel strand 1 position, dig concrete, equating bearing 7 will be gone up work anchor block 6, the anchor block 9 of working is enclosed within on the steel strand 1 and holds out against with bearing 7 down, with bolt 2 tighten and with wedge intermediate plate 5 with steel strand 1 anchoring.Near work anchor 8, will go up instrument anchor block 3, descend instrument anchor block 11 to be enclosed within on the steel strand 1, tighten with bolt 2.Steel strand 1 cut-out that will need again to remove part gets final product, and unloads moveable anchor 10 then, and work anchor 8 is started working, not loss of the stress of steel strand 1 in the whole construction course, and the prestressing force effect of remainder is unaffected.
Claims (3)
1. ground tackle, it comprises work anchor (8), moveable anchor (10), it is characterized in that described work anchor (8) comprises the work of the going up anchor block (6) that connects by bolt (2), the anchor block (9) of working down, on work anchor block (6), work and be provided with the wedge intermediate plate (5) of axial subdivision in the wedge hole that forms between the anchor block (9) down; Described moveable anchor (10) comprises the last instrument anchor block (3) that connects by bolt (2), following instrument anchor block (11), is provided with the steel strand hole between last instrument anchor block (3), the following instrument anchor block (11).
