With reference to figure 1, be depicted as a kind of for mentioning the anchor 10 of concrete component 12 (see Fig. 7).Shown anchor 10 is for mentioning the form of anchor in edge, and it should be appreciated by those skilled in the art that replacement example of the present invention can be the form of other type anchor, such as, anchor is mentioned in face.
Anchor 10 comprises one section of wall scroll wire rod or rod 14, and described wire rod or rod are bent to form a head that can engage with the hook of jacking system 16 and one for embedding the main part 18 in concrete component 12.Wire rod 14 is bent, the relative anchor leg 20,22 of main part 18 is extended in the plane that the plane with head 16 is substantially vertical.Because wire rod 14 bends by this way, can arrange anchor 10 like this makes relative anchor leg 20,22 be positioned in the plane substantially parallel with the central plane of concrete component 12, and head 16 carries out orientation with the median plane of concrete component 12 is substantially vertical.Advantageously, make anchor 10 be positioned at the bottom of concrete component 12 like this, be convenient to that edge is carried out to concrete component 12 and mention, and be conducive to the relative wide regional implementation of anchor leg 20,22 in concrete component 12.
Because anchor leg 20,22 outwards opens from central axis 24, have compared with the parallel typical anchor of anchor leg with may use, be applied to the load distribution on anchor 10 on the more large regions of concrete component 12.This thereby reduces the possibility mentioning concrete component 12 failure when mentioning, this is because make anchor 10 to be pulled at the concrete component 12 of mentioning large regions in process.Each anchor leg 20,22 can make wave-shaped configuration, increases surface area, to provide the additional anchorage of anchor 10 in concrete component 12 by being incorporated to a series of ripple.Advantageously, mentioning in process, ripple produces extruding to concrete, stops anchor leg 20,22 to be extracted from concrete.Like this, relative anchor leg 20,22 can provide the function same with the auxiliary connecting rod used in existing anchor, therefore, does not need independent pull bar.
In order to realize vertical stratification, the head 16 in shown example reverses 270 degree of angles around the central axis 24 of anchor 10 relative to main part 18.In other alternative anchors, in order to form vertical stratification, head can turn round around the central axis 24 of anchor 10 angle (or more generally reverse the angle of 90+180x, wherein x is integer) turn 90 degrees relative to main part 18.Central axis 24 is in the same plane with head 16.Like this, the plane of head 16 and the plane orthogonal of main part 18.
Should be understood that in other embodiments of the invention, main part 18 can be rotated relative to head 16 around central axis 24, makes the plane of main part 18 become other angle except 90 degree with the plane of head 16.In some special embodiments, this angle is about 60 degree, 45 degree, 30 degree or 15 degree, because suitable angle determines according to the shape of concrete component 12 and/or direction.
