Description

[Detailed explanation of the invention] This invention is suitable for use when building a house, such as when raising girders or beams onto pillars, or when lowering the mortise of a raised girder or beam into the tenon of a pillar. This allows one device to be used for a variety of purposes.

To build a house, pillars, girders, beams, etc. must be assembled, but in this case, the assembly work is difficult because the girders, beams, etc. to be assembled must be lifted and lifted to the top of the pillars.

Furthermore, in order to fit the tenon of a girder or beam into the tenon of a column, it was extremely dangerous because the girder or beam had to be struck with a hanging arrow over the girder or beam placed on top of the column.

Therefore, the present applicant has previously developed a tool as shown in FIG. 1 for the purpose of solving these problems.

This has an upward U-shaped receiving part b at the upper end of the handle a, and a girder or beam e is inserted between the side plates c and d of this deformed part b.
The handle 2 is lifted and these are pushed up to the top of the column f.

However, although this can lift girders, beams, etc.
Since it is not possible to hammer them downward, in order to fit the mortise of the lifted girder or beam e into the tenon g of the column f, climb up on the girder or beam e above the column f as before. You have to hit it with a hanging arrow.

In this case, even if girders, beams, etc. are lifted to the top of the pillars, the danger of having to work at a high place still remains unresolved.

The present invention was developed to eliminate these drawbacks, and it is not only possible to push up the girder or beam e, but also to fit the tenon and tenon without climbing onto the lifted girder or beam e. This allows for matching work.

The present invention will be described in detail below based on illustrated embodiments.

The tool of the present invention consists of a head 1 and a handle 2.

The head 1 has a recessed support part 3 on the upper surface on which girders, beams, etc. are placed when pushing them up the column, and on the lower surface, a support section 3 on which the girders, beams, etc. are placed when pushing them up onto the column is recessed. A bottom hammering part 4 is formed for driving the mortise of a girder, beam, etc. into the tenon of a column.

As clearly shown in FIG. 4, the head 1 of the tool shown in FIG. 2 consists of a base 5 made of an iron plate bent upward into a U-shape, end plates 6 attached to both ends of the base 5, and a top plate 7 placed over the top of the base 5. and reinforcing plates 10 and 11 inserted between both side plates 8 and 9 of the base body 5.

All of these members are made of iron plates.

Both side plates 8 and 9 have central portions 12 and 13 one step lower than both sides, and the top plate 7 also has a central portion 14 one step lower than both sides of the top plate 7 to serve as a support portion 3.

A protrusion 15 protrudes from the center of the top plate 7 into which a piece of wood such as a girder or beam placed on the support portion 3 pierces.

The handle 2 is made of two iron pipes 16 and 17 connected by screws.
The means for attaching this handle to the head 1 is as shown in FIG.

A shaft 19 welded to the top plate 7 and the bottom plate 18 is made to project downward from the bottom plate 18, the tip of the upper pipe 16 is placed over the shaft 19, and the tip and the shaft 19 are fixed with screws 20.

By doing this, the pipe 16 will not break or
If it becomes old, it can be replaced with a new one.

As clearly shown in FIG. 6, the head 1 of the tool shown in FIG. 3 includes an upward U-shaped base 21, an end plate 22, a tall end plate 23,
It consists of a top plate 26 in which protrusions 24 and through holes 25 are formed.

Each of these members is made of iron plate like the one in FIG.

The handle 2 has two iron pipes 16 and 17 screwed together like the handle shown in FIG. 2, and is attached to the head 1 as shown in FIG. 7.

The shaft 28 is passed through the top plate 26 and the bottom plate 27 and welded, the upper pipe 16 is placed over the protrusion 29 of the shaft 28 that protrudes downward from the bottom plate 27, and the pipe 16 and the shaft 28 are fixed with screws 30. There is.

By doing so, when the pipe 16 becomes damaged or old, it can be replaced with a new one.

Note that the support portion 3 of the tool shown in FIG. 3 is formed between the upwardly protruding portion 31 of the end plate 23 and the upwardly protruding portion 32 of the shaft 28.

Further, numeral 33 in FIGS. 2 and 3 is a rubber cap placed over the lower end of the handle 2.

To use the tool according to the present invention, proceed as follows.

To push girders, beams, etc. onto column f, move them as shown in Figure 8A.
Just place it on the support part 3 of the head 1 like a mouth, and in this state push the handle 2 upward.

The girder, beam, etc. placed on the column f, the mortise h, and the tenon g of the column f.
To fit it in, push up the handle 2 as shown in Figure 8, raise the bottom striking part 4 of the head 1 above the girder, beam, etc. e, and drop the bottom striking part 4 onto the top surface of the girder, beam, etc. e. do it.

In this way, the weight of the tool itself causes the girder and beam e to descend and the mortise h to fit into the tenon g.

To fit the mortise h of the girder, beam, etc. e into the horizontal tenon g shown in Fig. 8A, remove the lower pipe 17 of the handle 2 from the upper pipe 16, and hold the upper pipe 16 and insert it in the same way as for a hanging arrow. head 1
It is good to strike girders, beams, etc. with the side striking part 34 of the.

Although the above example of use is for assembling columns, girders, beams, etc., the tool of the present invention can also be used for other purposes, such as for disassembling houses.

As mentioned above, the present invention has a support part on the head, so it is very convenient because girders, beams, etc. can be placed on the support part and pushed up to a high place.

In addition, in this invention, the head has a bottom striking part and a side striking part, so it is not only possible to simply push girders and beams to a high place, but also to lower girders and beams downward from the ground. The tenon and tenon can be fitted together by tapping or tapping to the side, so the work is safer as there is no need to climb to a high place.

Furthermore, since the head is formed into a hollow shape by combining metal plates, it is lightweight despite having a bottom hitting portion and a side hitting portion, and is therefore easy to handle.

Furthermore, in the present invention, since the handle can be assembled and disassembled into two or more parts, if the handle is disassembled and shortened, it can be used as a hanging arrow, which is very convenient and easy to use.
