心合わせも容易になそうとするものである。[Detailed description of the invention] The present invention relates to a driving-type shear wall anchor that uses deformed reinforcing bars, round steel, etc. as the shaft member, and drives it into the floor to form the anchor, thereby reducing the vibration of the wall. The purpose is to sufficiently withstand the shearing force applied to the shaft member, to facilitate driving work, and to facilitate centering of the shaft member and the wedge.

がやりにくかつた。 Conventionally, as shown in FIG. 4, a conical portion 22 is formed at the end of a shaft member 21, and a shield 24 with a split groove 23 that is slidably fitted onto the shaft member 21 from the other end is struck to split the conical portion 22. A driving anchor in which the groove 23 is pushed open with a conical surface and is pressed against the inner wall surface of the pit 25 is known. According to this, the shaft member 21
Since it protrudes outward from the outer wall surface of the shield 24, the striking surface of the shield 24 is limited, making the striking work difficult.

め具も知られている。 Furthermore, according to the microfilm of Utility Model Application Publication No. 54-16974, a wedge body 6 is formed integrally with the main body at the root end of the main body 1 which is substantially cylindrical and has a groove 4 extending from the root 2 to the tip 3. , the outer diameter of the tip of the wedge body 6 is made approximately equal to the inner diameter of the hole 5 of the main body 1, and the diameter of the wedge body 6 in the root end direction is made larger than the inner diameter of the hole 5 of the main body 1. An embedded screw fastener for concrete structures is also known in which an ear portion 8 is provided at an extension position of the cut groove 4 in the peripheral wall.

面の中空部分だけ耐力が減少する。 This embedded screw fastener has a main body 1 having a cylindrical shape in order to screw together members such as wood screws 14 and screws. These members cannot be used for objects that exert large shear forces on these members, such as shear walls. Even if the cylindrical body itself were to receive shearing force, the yield strength would be reduced only in the hollow portion of the cross section.

ではない。 Further, the ear portion 8 is fitted into the cut groove 4 after the wedge body 6 expands the root portion 2, and the wedge body 6 is inserted into the wood screw 14.
This is to prevent the screw from being screwed into the main body 1 by a screwdriver, etc., and is not for regulating the direction in which the wedge body 6 and the main body 1 are fitted together.

の心合わせの容易化を解決できていない。 Further, according to Japanese Utility Model Application No. 48-69211, the groove width of the split 11 is uniform on the diameter of the bolt 8, and the thickness of the wedge packing 12 is also uniform in its cross section. Therefore, when driving, there is a risk that the wedge packing 12 and the split 11 may be displaced relative to each other in the diametrical direction of the bolt 8, and one of the problems of the present invention, which is to facilitate alignment between the shaft member and the wedge, cannot be solved. do not have.

で、作業性が甚だ悪い。 In addition, in Utility Model Application No. 48-29266, by turning the bolt 1, the wedge piece 2 screwed onto the bolt 1 moves in the axial direction of the bolt 1 and is press-fitted into the locking cylinder 5, thereby locking. A configuration is shown in which the tube 5 expands from the slit 4 and is pressed against the wall surface of the hole 10 with its outer peripheral surface. In this case, since it is not a drive-in type, the workability is extremely poor.

徴とする。 This invention uses materials other than wood screws and screws, such as deformed reinforcing bars and round steel, as the shaft member to withstand large shearing forces. This problem was solved by devising the cross-sectional shapes of the groove and the wedge. This drive-in shear wall anchor consists of a shaft member made of deformed reinforcing bars, round steel, or other material other than wood screws or screws, and a separate wedge.The shaft member has a split groove at its base end. The wedge has a reduced end face at one end and an enlarged end face at the other end, and the wedge is used by fitting four wedges together with the shaft member 1. has a widened portion at the axial center of the shaft member, the width of the reduced end face is smaller than the width of the split groove that should correspond to this width, and the width of the enlarged end face is smaller than the width of the split groove that should correspond to this width. Generally speaking, the shaft member and the wedge are driven relative to each other in a state in which the reduced end surface side of the wedge and the groove of the shaft member fit together, and the opening edge of the groove and the outer surface of the wedge are in close contact with each other. do.

Reference numeral 1 denotes a shaft member, which is made of deformed reinforcing bars, round steel, or other materials other than wood screws or screws. This shaft member 1 is provided with a split groove 3 having a widened portion 2 at the axial center at the base end. 4 is a wedge, at one end of which substantially matches the cross section of the groove 3 of the shaft member 1 or has its own width W 1S
, W 2S , etc. have reduced end faces 5 smaller than the widths G 1 , G 2 , etc. of the dividing grooves 3 that should correspond to these widths respectively,
The other end has an enlarged end face 6 whose widths W 1B , W 2B , etc. are larger than the widths G 1 , G 2, etc. of the grooves 3 that correspond to these widths. Substantially compatible means
This means that it is sufficient to be compatible within a certain range including the widened portion 2. Therefore, a widened portion 7 corresponding to the widened portion 2 is provided. This reduced end face 5 is necessary to first fit the wedge 4 into the split groove 3 when driving it into the end of the shaft member 1, and the enlarged end face 6 is necessary to spread the split groove 3 and transmit the hammering force into the concrete product. is necessary.

材１が傾いたりせず、耐荷力に偏りがない。 The illustrated driving anchor is used to attach deformed reinforcing bars or round steel to concrete products, and is placed in a pit 25 drilled into the concrete wall.
Insert the wedge 4 with the enlarged end surface 6 facing the pit end surface and fit the split groove 3 of the shaft member 1 into it, or fit the wedge 4 into the split groove 3 in advance and insert the shaft member 1, and then insert the wedge 4 into the split groove 3 of the shaft member 1. Tap the end face of member 1. The wedge 4 causes the split groove 3 to expand, and the outer end of the shaft member 1 comes into pressure contact with the inner wall surface of the pit 25. Thereby, the pull-out load applied to the shaft member 1 can be sufficiently resisted. Furthermore, during this tapping, the engagement between the widened portions 2 and 7 determines the directionality of the fit between the wedge 4 and the shaft member 1, so that the wedge 4 and the shaft member 1 are not twisted, and the two are positioned approximately on the same axis and are fitted together. do. Therefore, the shaft member 1 does not tilt, and the load carrying capacity is not biased.

できる等、種々の効果がある。 According to the present invention, materials other than wood screws, screws, etc., such as deformed reinforcing bars and round steel, are used as shaft members, so
Even if the shearing force that this shaft member receives from what it supports, as in the case of a seismic wall, is sufficiently strong, it can withstand it sufficiently. having a reduced end surface that substantially matches the cross section of the split groove or whose width is smaller than the width of the split groove whose width should correspond to this width, and at the other end the width of the split groove whose width should correspond to this width; The reduced end surface of the wedge, which has a larger enlarged end surface, is fitted into the split groove, and the split groove is expanded by hitting the shaft member, and the shaft member is pressed against the inner wall surface of the pit. This has various effects, such as keeping the directionality of the fitting constant, so that the shaft member can be accurately fixed in the pit without being twisted.
