DESCRIPTION:
BRIEF SUMMARY
TECHNOLOGICAL FIELD
This invention relates to a jointing method of framing members mainly suitable for constructing housing and other structures.
TECHNOLOGICAL BACKGROUND
So far, as framing wooden members in, for example, housing and other structures, what is called "solid shafts" cut out from lumber have been generally available, but recently as much more attention has been paid for the saving of natural resources and overhead costs have increased, it has been very difficult to obtain such members at a reasonable price. Therefore, a various shape of members have been proposed for the market. One of them is formed by solidly securing a plurality of wooden plates facing each other at a certain interval of spacing.
Framing members with such conventional construction are formed by solidly binding both members by adhesives or bolting after the end portion of one framing member is inserted into an opening in the other member.
With the framing members according to the prior art, however, until the connection portions are completely tightened with bolts or solidly fixed with adhesive agent, the connection portions must be temporarily fixed or a delicate positional adjustment of the connection portions must be made, thereby requiring much more labor or tools, thus resulting in an increased cost. In particular when used at a poor scaffolding made of longer materials like house or other building site, the temporary fixing work of the framing members is very dangerous.
To solve the above problems, this invention intends to provide a jointing method of framing members which can easily temporarily fix framing horizontal members to framing columns when building or assembling houses and other constructions.
DISCLOSURE OF THE INVENTION
To achieve the foregoing target, the jointing method of the framing members prepares one piece of framing column which is made by facing two slender members having the same shape of butt end to each other so as to provide a given width of opening; two pieces of framing horizontal members having the same sectional shape as the foregoing framing column; an opening joint fixture for attaching one of the two foregoing framing horizontal members so that the end surface is jointed along the side surface of the opening of the foregoing framing column; and a side joint fixture for attaching the other framing horizontal member so that the end surface is jointed along the side surface at right angle with the side surface of the opening of the foregoing framing column, and joints the framing column and the framing horizontal members by way of the opening joint fixture and the side surface joint fixture so that both framing framing members are placed at right angle with the framing column.
The foregoing opening joint fixture has a width equal to the opening, a fixing surface which fits into the opening of the framing column for attaching and a joint surface projecting from the opening side surface of the framing column. The joint surface has an introduction opening at the top edge, as well as a bolt receiving groove for holding a bolt at the groove bottom and a bolt through hole both disposed respectively at its upper and lower portions.
The foregoing side surface joint fixture has a width equal to the opening, a fixing surface which is attached to the side surface of the framing column and a joint surface projecting from the both sides of the fixing surface. The joint surface has an introduction opening at the top edge, as well as a bolt receiving groove for holding a bolt at the groove bottom and a bolt through hole both disposed respectively at its upper and lower portions.
The end portions of the both foregoing framing horizontal members have respectively a drilled upper bolt through hole and a drilled lower bolt through hole disposed so as to match the groove bottom of the bolt receiving groove and the bolt through hole.
The opening joint fixture and the side surface joint fixture are fixed to the framing column by way of the common fixing bolts, while the fixing surface of the foregoing op
