[0001]

[Industrial applications]

 The present invention relates to a tool used for assembling a horizontal member in the construction of a timber structure.

[0002]

[Prior art]

 When the foundation of the wooden building has been set up, through columns and side columns are erected and the lay between the columns is passed. After assembling the main part of the framework in this way, temporarily secure it to prevent it from collapsing. Next, re-distort and then attach the braces and braces to solidify the whole. Generally, heavy sideways such as a glove are carried to a high place by using construction machines such as cranes, but relatively light ones may be manually carried by a worker. .

Mortars and mortises are used when assembling the pillar and the sideways. One of the columns and the sideways has a tenon, and the other has a tenon that fits the tenon, and they are assembled together by fitting. As an example of such a case, the joint portion between the pillar and the sideways is shown in FIG.

A tenon 401b is provided on the lower surface of the end of the lying side 401, and a tenon 402b corresponding to the outer shape of the tenon 401b is provided on the upper end 402a of the column 402. The lower end of the pillar 402 is already attached to a base (not shown). When mounting the sideways 401 on the pillar 402, the mortise 401b and the mortise hole 402b are fitted, but the mortise, which is the fitting work, is performed by a jumping craftsman or the like to adjust each member to a high place. While doing this, the sideways 401 that have been transported to a high place are assembled into the pillars 402.

【Example】

 FIG. 1 shows the structure of a high place assembly tool according to an embodiment of the present invention. In this embodiment, the head 2 is connected to the tip 11 of the handle 1 as a rod-shaped member. The head 2 is a flat steel material having a certain thickness, and has a concave portion 3 serving as a holding portion, a lower contact plate 4 serving as a lower contact portion, and a side contact plate 5 serving as a side contact portion. .

The recess 3 is provided so that one side of the head 2 is cut out, and opens from the front end 11 of the handle 1 in the axial extension direction (upward). As shown in FIG. 2, since the sideways 401 is inserted in the recessed portion 3, the opening width may be a dimension through which the sideways lower surface 401a passes.

On the bottom surface 31 of the concave portion 3, two protrusions 6 facing the opening direction are provided as a slip preventing member. Since the apex of the projection 6 has an acute angle, as shown in FIG. 2, when the sideways 401 is contained in the recessed portion 3, the sideways 401 digs into the lower surface 401a to some extent. Therefore, the sideways 401 is restrained from moving in the recess 3. Further, since the sideways 401 is supported at the bite position by the projection 6, even if the high-position assembly tool is tilted with respect to the sideways 401 to some extent, it does not slip out, and the above-mentioned sideways movement is prevented. Has a suppressing effect.

As shown in FIG. 3A, as a non-slip portion instead of the projection 6, a small projection 301, which is formed on a file surface, for example, is formed on the bottom surface 302 so that the friction coefficient becomes very high. It may be carved into. In this case, if the cross-sectional shape of the bottom surface 302 is formed into a mountain shape as shown in FIG. 3B, even when the assembling tool for high places is tilted with respect to the lying side 401, as in the case where the protrusion 6 is provided. It is possible to maintain the sideways motion suppression effect. Further, such a member may be formed of a member having a large frictional force such as rubber.

Both the lower backing plate 4 and the side backing plate 5 are flat steel members having a certain thickness similar to the head 2. The lower backing plate 4 is fixed near the connection between the handle 1 and the head 2 so as to have a flat surface in the direction opposite to the opening direction. The side contact plate 5 is fixed to one side surface near the tip of the head 2 so as to have a plane orthogonal to the surface of the head 2. Further, it is preferable to provide an elastic body made of rubber on these surfaces.

The assembling according to this embodiment is performed as follows. An operator at a position lower than the upper end of the pillar, such as the ground, lifts the sideways 401 by the recess 3 of the above-ground height assembly tool, and temporarily puts the sideways 401 between the pillars. After that, the mortise and the mortise are aligned, but if they fit together in the placed state, they are fitted as they are. If it does not fit properly, tap it with the lower backing plate 4 from above to push down the side 401. If it still does not fit well, lift the sideways 401, correct the misalignment with the side contact plate 5, and adjust the position, and the sideways 401 will be tense due to its own weight. If the tenon is not found even after the alignment, further lay down the side laying 401 with the lower backing plate 4 from above to perform tenon.

The lower backing plate 4 and the side backing plate 5 are firmly fixed so as to withstand the impact. Furthermore, in this embodiment, since steel is used as the material, the tool for assembling high places itself has a certain weight, and when the sideways 401 is pressed down, it can be easily performed by using its own weight. it can.
