2. Description of the Related Art A roof base material 1 shown in FIG. 7 has been proposed by the same applicant as the present application in order to facilitate the construction of a large roof such as a factory building (for details, see Japanese Patent Application No. 3-81571). . This roof base material 1 is a fire-resistant base plate 2 on which a metal corrugated plate 3 is attached. According to this roof base material 1, since the bending strength of the base material itself increases, a conventional fire-resistant base plate is used. A much larger roof base material (width dimension 2-3
It is possible to manufacture meters, a vertical dimension of about 6 mails, and a weight of about 500 kg), and installing these roof base materials on the roof structure using a crane (not shown) has the advantage of significantly reducing the roof construction time. is there.

However, the work of mounting the roof base material 1 has the following problems. (I) Generally, since the crane for loading and unloading is low in the accuracy of the unloading position when the load is hung, when installing the roof base material 1, the worker is placed in advance at a key part of the roof structure. Since the displacement of the lowering position is adjusted, a lot of man-hours are spent for mounting work. (Ii) Since the above-mentioned adjustment work by the worker is performed at a high place where the scaffolding is imperfect, the work safety is impaired.

In view of the above problems, the present invention provides a roof base material that can facilitate the work of mounting a large roof base material by a crane, improve the work efficiency, and at the same time ensure the safety of work in high places during mounting. It is an object to provide a mounting guide device.

In order to solve the above-mentioned problems, the present invention comprises two means comprising the following claims. (1) [Claim 1] A plurality of beam members attached to the lower surface of the roof substrate and having an opening at one end, a receiving member protruding from the opening end of each beam member, and a beam member of each beam member. A rod-shaped fitting member protruding from the other end and having a sharpened tip is provided, and the receiving member is erected on a bottom plate that is wider than the bottom surface of the fitting member tip and an edge of the bottom plate. A guide plate is formed into a box shape having an upper end and both ends in the length direction of the beam member opened, and a cross section of the insertion member is set so that the insertion member fits into the opening of the beam member. A guide device for mounting a roof base material, which is characterized in that (2) [Claim 2] A plurality of beam members attached to the lower surface of the roof substrate and having an opening at one end, a receiving member protruding from the opening end of each beam member, and A rod-shaped fitting member protruding from the other end and having a sharp tip, and each receiving member is formed in a gutter-like shape of a lower recess in which both ends in the upper direction and the length direction of the beam member are open. A guide device for mounting a roof base material, wherein the fitting member is fitted into the receiving member from above and the cross section of the fitting member is set so as to fit into the opening of the beam member.

[0006]

(I) According to claim 1, since the bottom plate of the receiving member has a larger spread than the bottom surface of the tip end portion of the fitting member, the tip end portion of the fitting member of the roof base material to be suspended is the roof base material already mounted. It can be easily received by the receiving member. Further, according to claim 2, since the cross section of the fitting member is set so that the fitting member is fitted into the receiving member from above,

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a first embodiment of the present invention. The main part of this embodiment is a plurality of (three sets in FIG. 1) guide devices 12, 1 attached to the lower surface of a roof substrate 11.
It is composed of 2 and 12. Each guidance device 12
A tubular beam member 13 having a rectangular cross section, and this beam member 1
2 is formed by a receiving member 14 and a fitting member 15 and the like projecting from both ends of the beam 3, and the upper surface of the beam member 13 is shown in FIG.
As shown in, the bottom plate 16 is fixed to the lower surface.

Each receiving member 14 is composed of a trapezoidal bottom plate 17 having a shape close to a right triangle, and two guide plates 18a and 18b standing on the edge of the bottom plate 17 at a portion corresponding to the hypotenuse of the trapezoid. The bottom plate 17 is butt-welded to the lower side of the opening end of the beam member 13 at a portion corresponding to the upper side of the trapezoid (see FIG. 2). The bottom plate 17 has a sufficiently large expansion as compared with the bottom surface 20 of the fitting member tip portion 19 described later.

The two guide plates 18a and 18b each have an elongated rectangular shape, and the portions corresponding to the short sides of the rectangular shape are butt-welded to both ends of the opening 22 of the beam member 13. That is, according to this arrangement, the beam member 13 is provided in the inner part of the guide passage which is tapered inward.
This means that the hollow part of is open.

The fitting member 15 has a rod-like shape with a sharp tip portion 19, and the shape and size of the cross-section of the rod-like portion 21 are the same as the beam member, as shown in the handling procedure of the guide device described later. It is set so as to be fixed immovably when it is fitted into the opening 22 of 13. As shown in FIG. 2, the flange 2 is provided on the lower surface of each beam member 13 near the receiving member 14.
3 is attached, which supports the roof substrate 11 on the purlin 25 and is fixed in place by bolts 26 penetrating the flange 23.

Next, the handling procedure and operation of the guide device 12 will be described. First, as shown in FIG. 3, the roof base material 11 to be mounted is hoisted by the crane 27, and then, is hung down to a position almost adjacent to the roof base material 11 already mounted. By this operation, the tip end portions of the fitting members 15, 15, 15 receive the receiving members 14, 14, of the roof base material 11 already mounted,
Received by 14. At this time, since the bottom plate 17 has a sufficiently large spread as compared with the bottom surface of the tip end portion 19 of the fitting member 15, it is possible to absorb inaccuracy in the unloading position of the crane 27. Therefore, a worker for adjusting the unloading position as in the conventional case is unnecessary.

Next, the roof substrate 11 is pulled laterally (see arrow a in FIG. 3) by using, for example, a rope (not shown). By this operation, each fitting member tip portion 19
Moves forward along the guide plate 18a as shown by arrows b, c and d in FIG. 4, and finally fits into the opening 22 located at the back of the receiving member 14 (see phantom line). At this time, the fitting member 1
Even if the traveling direction of 5 shifts to the side, the guide plate 18a or 18
b prevents it from falling off the receiving member 14.

When the fitting member 15 is fitted into the opening 22 of the beam member, the positioning of the roof base material 11 is almost completed.
When the crane is further unwound to a low position, the flange 23 of the support leg 24 descends on the purlin 25 as shown in FIG.
Here, when the flange 23 is bolted to the flange 28 of the purlin 25, the mounting of the roof base material 11 is completed.

As shown in FIG. 3, the roof base material 11 is indicated by an arrow a.
Since the work of pulling in the direction is performed by a worker (not shown) located on the roof base material 11 which has already been mounted, the work is safe and reliable.

A second embodiment of the present invention is shown in FIG. In this example, the bottom plate 17a of the receiving member 14a is formed into a rectangular shape, and the tip end portion 19a of the fitting member 15a is bilaterally symmetrically pointed. Other than that, there is no difference from the first embodiment.

A third embodiment of the present invention is shown in FIG. The receiving member 14b in this example is formed in the shape of a trapezoid whose cross section is downward, that is, in the form of a gutter in which the guide plates 18d and 18e on both sides are inclined inward. Further, the fitting member 15b has a trapezoidal shape whose cross section is downwardly recessed so that the fitting member 15b is fitted into the receiving member 14b from above.
Further, the tip portion 19b has an inclined boat bottom-shaped bottom surface 20a.

According to this embodiment, when the fitting member 15b is placed on the receiving member 14b, the fitting member 15b is placed.
Since the openings 22a of the beam member 13 are concentric with each other, there is an advantage that a roof base material (not shown) can be easily positioned.

It should be noted that the present invention is not limited to the above-mentioned embodiment, for example, the roof base material may be a corrugated plate without a base plate, and the number of guiding devices is the same as the roof base material. Within the scope not departing from the gist of the present invention, there may be two sets or four sets or more depending on the size, and the receiving member and the fitting member may have different shapes. Of course, various changes can be made.

[0019]

[Effects of the Invention] As described above, the present invention exhibits the following excellent effects. (I) According to claim 1, since the bottom plate of the receiving member has a larger spread than the bottom surface of the tip of the fitting member, the tip of the fitting member of the roof base material to be suspended is the receiving member for the roof base material already mounted. Easily accepted. Further, according to the second aspect, since the cross section of the fitting member is set so that the fitting member is fitted into the receiving member from above, the fitting member can be easily received by the receiving member of the roof base material already mounted. Therefore, it is not necessary to arrange a worker for adjusting the displacement of the unloading position of the crane, and the efficiency of the cargo handling work can be improved. (Ii) When the roof base material suspended in the above state is pulled in the lateral direction, the fitting member is guided by the guide plate of the receiving member or along the inside of the trough-shaped receiving member, and the fitting member is a beam member. And the roof base material is positioned at a predetermined position. At this time, there is no risk that the fitting member will slip off the receiving member, and the positioning operation of the roof base material is safe and easy. (iii) Since the positioning work of the roof base material described in the above (ii) is performed by the worker located on the roof base material which has already been mounted, the worker's foothold is wide and solid, It is possible to secure the safety of work in high places.
