Description

The present invention relates to a connecting structure for walls and columns in the assembly process.

Originally, the wall in wooden construction is generally a large wall method that secures the strength by attaching a board to the pillar together with braces. It is also abandoned in the mountains and fields, and for the purpose of forestry and flood control and decarbonization activities that should be dealt with against natural disasters, it is necessary to use wood to make wooden structures, and to make construction methods simpler and labor-saving. Instead, we should enjoy the properties of wood such as heat retention, moisture retention, heat insulation, soundproofing, etc., but today, when there is a lack of efforts to protect the natural environment, we provide a construction method that has been pursued with a connected structure. .

Regarding the effects of counterbore processing, cutout diameter, and woodwork on connecting jigs loaded on pillars, shown in Patent No. 7117449, which the applicant has acquired and is publicly known, horizontal reinforcement loaded on wall members The problem is how to remove the complicated feeling in the process of shaping, processing the end of the rectangular timber to be connected with a bolt to the nut with a seat attached to the pillar by horizontal drilling, and the restoration process to the wall surface.

In addition, with respect to the publicly known rights that the applicant has acquired, there is a need to reduce the strength of the pillars during countersinking when loading connecting jigs, and a plurality of tiers that allow wall members to be constructed. For square timbers, in order to reduce the complexity of the process of woodwork and connection for loading horizontal bars to the ends, connecting jigs are used to simplify and labor-saving horizontal drilling and counterbore processing for connecting to the pillars. In order to fix the fittings and the wall member opposite to the pillar, it is required to connect to the pillar from four directions and four other connection types in a simple and labor-saving manner.

Therefore, the measures for wooden construction, including the realization of a sturdy frame with existing members and jigs, and the construction method that responds to the shortage of craftsmen such as workers by pursuing simplification and labor saving, include low-grade materials. In the construction of wall members that can be manufactured from such materials without large-scale equipment, large-scale efforts have been made to try small-scale forestry over a wide area, making use of the small turns seen in self-cutting forestry, which has been praised in recent years. Even without manufacturing, it is possible to deal with the connection structure of walls and pillars constructed by supplying with a simple manufacturing method, including processing and development of members.

The wall members are made up of connected rectangular timbers, including the ends of irregular lengths, and are stacked, and the flat steel and wooden packing are inserted into the grooves machined on the stacked surface at the determined positions. Installed with a flat steel narrower than the width, filled with wooden packing from both sides to improve airtightness, drilled through holes from the top side to the bottom side, and inserted a round steel bar as a vertical bar, equivalent to the acquired rights , and connect it to the construction of the wall members with a wooden structure that encloses reinforcing bars in all four directions.

Furthermore, the installation position of the horizontal reinforcement loaded in the wall member of the stacked structure of rectangular timbers is determined as a base point, and the horizontal perforation position for connection to the vertical groove of the column processed on all sides is also determined, and the rod-shaped protrusion is fixed to the plate. is mounted flat on the groove bottom of the pillar, and the fixing position is allocated from the base point, and the plate is fixed flat to the groove bottom of the pillar with a nut using a bolt with screws on both ends in a horizontal hole, and the wall A connection hole is also formed in the member at a position excluding the counterbore dimension with respect to the end of the horizontal reinforcement of the loading, and the loading is made to project from the wall member to the bottom of the groove of the column. A connection characterized by the pursuit of simplification and labor saving in the connection in which the end portion and the rod-like projection are connected inside the groove of the opposing surfaces of the column and the wall member in order to fit the fixed plate. Structure.

According to the present invention, the lateral ribs of the loading form a connection hole in a portion excluding the thickness dimension of the plate from the end, and protrude from both ends of the wall member with a length reaching the groove bottom of the counterbore into the groove of the column. It is loaded and positioned on the pillar with the horizontal center of the horizontal reinforcement as a base point, and the plate to which the rod-shaped projection is fixed is transversely drilled into the pillar, and a bolt with both ends is inserted through the pillar and fixed with a nut. A connection structure in which the protruding ends of the horizontal ribs are pressed down together with the wall from the upper side of the rod-shaped projection of the plate while being pressed against the bottom of the processed groove on the column. Labor can be saved in the process of simply connecting a certain pillar and wall.

In FIGS. 1 to 3, the plate 6, which is loaded by countersinking the depth of the groove of the column 2 by the thickness of the flat steel, is made of flat steel with a common length and can be cross-connected, and has screws on both ends. A bolt 4 is fixed by a nut 5 so as to be cross-inserted, and the end of the horizontal reinforcement 3 loaded on the wall member 1 is extended to both ends of the wall member 1 to the bottom of the groove for counterbore processing. 3. At the same time as the base counterbore 11 of the plate 6 is applied to the vertical groove of the column 2, the base counterbore 11 of the plate 6 is countersunk by a length obtained by adding the tenon length of the column 2 to move the groove bottom. A plate 6 with a bar-shaped projection 7 fixed to the wall member 1 to be connected to the wall member 1, and a plate 6 fixed to the side of the column 2 is inserted into the horizontal hole and connected to a bolt 4 with screws on both ends. The mounting position is determined from the base point 12 with respect to the column 2 and fixed to the connection jig r so that the connection structure in the joining process can be a simple, simple and labor-saving process. This is the reason why the insertion of the intersecting horizontal holes is shifted by one bolt and the plate 6 is also made to have a common length while being installed in the same horizontal position.

In FIG. 4, in the step of combining the wall member 1 and the column 2 and inserting the tenon h of the column 2 into the tenon hole b, the length of the tenon h is added to the counterbore 11 of the base. A connection hole 15 is also formed in the projection 7 fixed to the plate 6 and the projecting part of the horizontal reinforcement 3, and the wall member 1 and the column 2 are joined inside the groove 17 facing each other. In order to execute the above, a pair of walls and the wall side of pillar 2 are pressed against the pillars erected at the beginning, and the tenon of one pillar is inserted into the tenon hole to form a connection.

In addition, inserting the steel material itself instead of packing into the groove of the overlapping surface of the stacked square timbers is avoided, and the narrow flat steel is made to match the groove width with thin wooden packing 8 from both sides, and the wall composed of square timbers. Regarding the wiring inside, a wiring groove 16 is drilled in the lower side of the wooden packing 8 insertion part at a determined position, and the extension of the wiring groove 16 is also drilled at the same position to the above-mentioned pillar 2 in a cross shape to the wall and the above-mentioned pillar 2.
