Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a handle driving device used for fitting the bottom of a column to a beam or foundation material of a wooden structure or wooden building.

"Conventional technology" The conventional method of assembling a wooden structure and a wooden building is to attach the columns to the upper beams, and then a worker climbs onto the upper beams and uses a mallet to attach the columns. Generally, the upper plane of the upper beam member is struck, and the lower end of the column member is fitted into the hole provided in the lower beam member or the base material.

``Problems that the idea aims to solve'' As mentioned above, work at heights is unavoidable when assembling frames, and there is a danger of workers falling, especially when assembling a high-rise roof with two or more floors. , efficiency decreases.

"Means for Solving the Problem" A weight guide movably penetrating the impact weight so that the worker can easily hit the upper plane of the upper beam at a low position below the upper beam. The beam plate fixed perpendicularly to the upper end of the rod is suspended by engaging with the upper plane of the upper beam where the column is attached, and the worker attaches the handle rod attached to the guide rod. While grasping the weight, manually lift the impact weight along the weight guide rod and repeatedly drop it from an appropriate height until the impact weight hits the restraint plate fixed to the lower end of the weight guide rod. The object of the present invention is to provide a driving device that can apply the impact force that is applied upon contact to the upper plane of the upper beam through the weight guide rod and the beam plate, thereby solving the problem.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the structure described in the example,
The present invention is not limited to the shape, relative arrangement, etc., unless specifically described.

Fig. 1 is a front view of the embodiment and also shows the relationship between the beams and columns, and Fig. 2 is a plan view of the embodiment and Fig. 3
The figure is an enlarged partial vertical sectional view of the same embodiment. As shown in each figure, at the upper end of the weight guide rod 2, there are two beam plate attachment rods 5 that extend outward from the weight guide rod 2 and are attached with a hanging plate fixing plate 6 for welding, etc. Therefore, it is fixed to the guide rod 2 at right angles, and the beam plate 1 is fixed to the lower surface of the beam plate hanging rod 5 by welding or the like. 7
is a beam plate reinforcing body for further firmly fixing the beam plate 1, the beam plate hanging rod 5, and the hanging rod fixing plate 6 to the weight guide rod 2 to give rigidity to the beam plate 1. . Weight guide rod 2
passes through a hollow hole 3' formed from the weight upper end surface 3A to the weight lower end surface 3B of the impact weight 3, and the impact weight 3 is loosely fitted so as to be movable along the guide rod 2. A restraining plate 4 is fixed to the lower end of the guide rod 2 to prevent the impact weight 3 from coming off the guide rod 2 and to generate an impact force, and a rod fixing plate 6 is attached to both ends. A handle rod 8 is attached to the outer peripheral edge of the restraining plate 4 and has its upper end firmly fixed with a reinforcing brace 9 in parallel to the weight guide rod 2. Note that the beam plate 1 may have a structure and shape other than this example in order to be firmly fixed to the weight guide rod 2, and the handle rod 8 may also be attached to the impact weight 3.
It is not necessary to make it parallel to the weight guide rod 2 as long as it is attached so that it can freely move along the weight guide rod 2 and collide with the restraining plate 4 to generate a striking force. FIG. 4 is an enlarged partial longitudinal cross-sectional view showing an impact weight 3 of another embodiment, in which a hollow hole 3' is bored from the weight upper end surface 3A to the weight lower end surface 3B of the cylindrical impact weight 3, and the outer circumferential surface 3C is A non-slip handle surface 3D that is easy to grip is formed. FIG. 5 is an enlarged partial vertical sectional view showing an impact weight 3 according to another embodiment, in which a cylindrical rubber or cylindrical plastic handle is attached to the outer circumferential surface 3C of the cylindrical impact weight 3 by gluing or shrink crimping. It is to be wrapped. If the total length of the weight guide rod 2 in each of the above-mentioned embodiments is about 2500 mm and the weight of the impact weight 3 is 5 to 6 kgf, it is easy to use for general work.

"Operation" In FIG. 1, the beam plate 1 is engaged with the upper plane 10' of the upper beam member 10 to suspend the pouring device of the present invention,
The operator grasps the handle rod 8 with one hand, grasps the outer circumferential surface 3' of the impact weight 3 with the other hand, lifts it upward along the weight guide rod 2, and releases the hand from an appropriate height to release the impact weight 3. falls along the weight guide rod 2, collides with the restraining plate 4, and stops, but the impact force generated at this time is transmitted to the upper beam member through the weight guide rod 2, the beam plate hanging rod 5, and the beam plate 1. 10 and the pillar material to apply impact force. By repeating the above operation, the lower end of the pillar material becomes 11'.
is cast into the bottom hole of the lower beam member or foundation member 12 and acts to fit into the hole.

``Effect of the invention'' Due to the structure and operation described above, the pouring device of the present invention is highly effective in increasing the safety and work efficiency of the frame assembly work of wooden structures and wooden buildings.
