Abstract

(57) [Summary] [Purpose] The present invention can be widely used in construction and other construction fields. [Structure] When there is a cavity between the outer wall and the inner wall of an existing building, mounting bolts cannot be embedded when installing equipment or building hardware. This is a cross anchor that can be attached from the outside regardless of the internal state of the.

[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention can be widely used in construction work and other construction fields.

[0002]

[Prior art]

 In the conventional construction, when equipment and building hardware etc. are attached to the wall of a building with cavities, the equipment and hardware are mainly attached to the horizontal members fixed to the pillars using the horizontal members between the pillars. Construction is done by the method, but the construction becomes complicated.

[0003]

[Problems to be solved by the device]

 In the conventional construction, there were problems such as the selection of an appropriate construction method and the strength of the construction after construction.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, by using the cross anchor of the present invention, the construction can be performed accurately and easily regardless of the internal condition of the wall.

[0005]

[Action]

 Drill a hole of the thickness of the cross anchor at the specified position on the wall, loosen the tightening nut of the cross anchor sufficiently, and make the vertical pin direction indication notch 8 at the tip of the bolt vertical so that the vertical pin is inside the cavity. Is lowered vertically and the bolt is fixed to the wall by tightening the tightening nut.

[0006]

【Example】

 Examples will be described with reference to the drawings. In FIGS. 1 and 2, when the metal piece 6 to be attached is attached to the wall 7 having a hollow back surface using a cross anchor, a hole having the thickness of the cross anchor is drilled at a designated position on the wall, Loosen the tightening nut 2 of the cross anchor sufficiently, insert the vertical pin direction indicating cut 8 at the tip of the mounting bolt horizontally into the through hole, and rotate the vertical pin direction indicating cut 90 degrees in the vertical direction It becomes vertical, and when the mounting bolt 3 is pulled, the vertical pin 1 is hooked on the back side of the wall and tightened with the tightening nut 2. If the mounting bolt 3 co-rotates when tightening the tightening nut 2, it is possible to prevent co-rotation by inserting and holding a slotted screwdriver in the notch of the vertical pin direction indicator notch 8. come. When it is necessary to pull it out, loosen the tightening nut 2 sufficiently, push in the mounting bolt, and pull the wire 4 from the pulling-out so that the vertical pin 1 becomes parallel to the mounting bolt 3 and can be pulled out.

[0007]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects.

At the time of construction, since the construction can be performed by simply drilling through holes having the thickness of the cross anchor to be used, the construction is easy.

Construction is possible regardless of the structure on the back side of the designated portion of the wall to be constructed.

No special tool is required because the drilling is only necessary for the construction.

Since equipment and building hardware can be fixed by tightening with the tightening nut 2, the construction can be robust and reliable.

If the vertical pin 1 is made parallel to the mounting bolt 3 by drawing a wire 4 from the drawing through the hollow portion of the mounting bolt, the vertical pin 1 can be withdrawn and can be reused.

The mounting bolt has a wide range of use by making various standards with different lengths and thicknesses.

[Brief description of drawings]

FIG. 1 is a state in which a cross anchor is inserted into a through hole and a vertical pin 1 is about to become vertical.

FIG. 2 shows a state in which the building metal fitting 6 is fixed to a wall surface.

FIG. 3 is a side view of a cross anchor.

FIG. 4 is a side view obtained by rotating FIG. 3 by 90 degrees.

5 is a front view of FIG. 4. FIG.

Claims (1)

[Scope of utility model registration request] 1. When an existing building has a hollow space between the outer wall and the inner wall, mounting bolts cannot be embedded when mounting equipment or building hardware. This is a cross anchor that can be attached from the outside regardless of the state inside the gap.
