Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jig for mounting an extruded cement board.

[0002]

[Prior art]

 As shown in Fig. 4 (a), the extruded cement board a used as the exterior material of a building has cavities b arranged side by side along the longitudinal direction. An angle d, which is usually welded to a beam c of a steel frame structure or the like, is fastened and fixed by a plate-like clip fitting e called a Z clip, a bolt f and a plate-like nut g. That is, a mounting hole is formed on the inner surface side of the extruded cement board a, and the plate nut g is inserted from the end using the cavity b as shown in FIG. 4B, and a position matching the mounting hole. , The one end of the clip metal fitting e is applied to the angle d, and the bolt f is inserted through the hole formed in the other end to be extruded to penetrate the mounting hole of the cement plate a and the plate nut g. The extruded cement plate a is clamped by the clip metal fitting e and the plate nut g, and is fixed to the angle d by screwing.

[0003]

[Problems to be solved by the device]

 According to the method for mounting the extruded cement board as described above, when the mounting hole is located near the upper end (or lower end) of the extruded cement board a, insert a finger into the cavity b and insert the plate nut. g can be held and the work of fitting the bolt f into the screw hole of the plate nut g can be done relatively easily, but the mounting hole is far from the upper end (or lower end) of the extrusion molded cement board a. In this case, since the fingers cannot reach to that place, it is impossible to insert and hold the plate nut g. Therefore, for example, the bolt f is fitted while pressing the plate nut g with an elongated plate piece or the like. It was difficult to do so and was a cause of reduced efficiency.

The present invention has been made to solve such a conventional problem, and even if the mounting hole of the extrusion molded cement plate is located far from the end, the plate nut can be easily inserted into the cavity. It is an object of the present invention to provide a mounting jig for an extrusion-molded cement board, which is capable of being surely held according to the mounting hole.

[0005]

[Means for Solving the Problems]

 As a means for technically solving this problem, the present invention is characterized by at least including a rod having an appropriate length and a nut holding portion having a magnet at a tip portion of the rod. is there. Further, the nut holding portion is provided with a receiving plate for abutting the nut, and the rod is provided with a position regulating member which is slidably fitted and can be fixed at an arbitrary position. The gist of the invention is that it is adjustable and a handle is formed at the end.

[0006]

[Work]

 With the nut attracted and held by the magnet of the nut holding part, push out the tip of the rod, insert it into the cavity from the end of the molded cement plate, and push out the position control member that is fixed in place in advance. If it is applied to the end face of the, the screw hole of the nut can be pushed out and aligned with the mounting hole formed in the molded cement plate, and it can be held as it is. Therefore, even if the attachment hole of the extruded cement plate is far from the end and the fingers cannot reach it, the nut can be inserted and held at a position corresponding to the attachment hole.

[0007]

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a rod having an appropriate length, and a nut holding portion 4 having a magnet 3 for attracting and holding a plate-shaped nut 2 is formed at a tip portion thereof. A receiving plate 5 having an L-shaped cross section is fixed, and a handle portion 1a is formed at the other end of the rod 1.

Reference numeral 6 denotes a position regulating member, which has a cylindrical portion 6a and a rectangular stopper plate 6b attached to its end, and is slidably fitted to the rod 1 and provided on the cylindrical portion 6a. The rod 1 can be fixed to any position by the thumbscrew 6c.

The mounting jig according to the present invention is configured as described above, and as shown in FIG. 1, the extruded cement plate is used in a state where the plate nut 2 is attracted and held by the magnet 3 of the nut holding portion 4. The screw hole 2a of the plate nut 2 can be aligned and held with respect to the mounting hole 7b provided in advance at an appropriate position by inserting it from the end of 7 into the hollow portion 7a.

FIG. 2 shows an example of the work, in the case where the extruded cement board 7 is attached as an outer wall material, and the angle 9 welded to the beam 8 of the steel frame structure or the like on the body side as in the conventional case. On the other hand, a plate-shaped clip metal fitting 10 called a Z clip and the plate-shaped nut 2 are used to fasten and fix with a bolt 11.

That is, the plate nut 2 is attracted to the magnet 3 of the nut holding portion 4 and the upper end portion thereof is brought into contact with the receiving plate 5, the grip portion 1a is gripped and the tip portion of the rod 1 is extruded. When the stopper plate 6b of the position regulating member 6 comes into contact with the upper end of the extrusion molded cement plate 7 when it is inserted into the cavity 7a from the upper end of the front plate 7, the insertion of the rod 1 is stopped.

At this time, the plate nut 2 is in close contact with the inner wall surface of the hollow portion 7a of the extruded cement plate 7, and the screw hole 2a and the mounting hole 7b are aligned with each other. In order to align both of these holes, the fixing position of the position regulating member 6 is measured and set in advance, that is, the stopper plate of the position regulating member 6 is located from the center of the screw hole 2a of the plate nut 2. The distance L up to 6b is matched with the distance from the center of the mounting hole 7b of the extrusion molded cement plate 7 to the upper end.

After that, the upper end portion of the clip metal fitting 10 is applied to the angle 9, the hole 10a formed at the lower end portion is aligned with the mounting hole 7b, and the bolt 11 is inserted, so that the screw hole of the plate nut 2 is inserted. The extruded cement plate 7 can be fixed to the angle 9 by being screwed onto the screw 2a and tightened to sandwich the extruded cement plate 7 with the clip metal fitting 10 and the plate nut 2. When the bolt 11 is tightened, the receiving plate 5 functions to prevent the plate nut 2 from rotating, so that the bolt 11 can be easily tightened without rotating together.

If the nut holding portion 4 is separated from the plate nut 2 after screwing, the rod 1 can be easily pulled out from the hollow portion 7 a of the extrusion molded cement plate 7. In this way, the upper end portion (usually two places on the left and right) of the extruded cement plate 7 can be attached to the body side.

Although not shown, the lower end portion of the extrusion molded cement plate 7 can be mounted in exactly the same manner by inserting the mounting jig from the lower end portion into the hollow portion 7a. Further, the extruded cement board 7 may be mounted sideways. In such a case, a mounting jig can be used by inserting it into the cavity from the left end or the right end.

When mounting not only the upper and lower end portions of the extruded cement board 7 but also the middle portion, the length of the rod 1 must be considerably increased. In such a case, although not shown, the rod This can be easily dealt with by making it possible to add the intermediate portion or by forming the entire portion in such a manner that the entire portion can be extended and retracted and the length can be adjusted.

The handle may be made of wood or synthetic resin, for example, and may be separately attached to the rod. Furthermore, the rod can have a non-circular cross section or a plate shape, and accordingly, the shapes of the nut holding portion, the receiving plate, and the position regulating member can be appropriately changed in design. It is not limited to the examples.

[0018]

[Effect of device]

 As described above, according to the present invention, the nut can be easily inserted into the cavity when the extruded cement plate is mounted by using the mounting jig having a simple structure, and the nut is aligned with the mounting hole. Since it can be securely held, even if the mounting hole is located far from the end, the mounting work via the clip metal fittings and bolts can be performed easily and efficiently, and its practical effect is extremely high. It is remarkable.
