Description

  The present invention relates to a hardware for building that can be reinforced and squarely used for a building such as a house.

  Conventionally, in a frame structure such as a wooden building, a wooden reinforcing material such as a cane is used as a method for reinforcing a joint between a vertical material such as a column and a horizontal material such as a beam. By attaching this cane to each structural member at an angle of 45 degrees with respect to the vertical and horizontal members, the corners of the frame, which are the joints of the vertical and horizontal members, are solidified, and in the horizontal direction due to earthquakes, winds, etc. The frame is prevented from deforming when subjected to great force. Such a reinforcing material is processed into a required length and shape at a construction site, and is fixed to a corner of the frame using bolts, a scourer, or the like. These operations require labor and time, and require a certain degree of experience and skill.

  Therefore, there has been proposed a reinforcing hardware for construction that reduces the labor and time of construction and does not require so much experience and skill (see, for example, Patent Documents 1 and 2). This reinforcing metal fitting for construction is obtained by straddling a steel plate member or a triangular reinforcing steel plate over a rectangular steel plate having a plurality of nail holes or bolt holes.

  In the reinforcing metal hardware for building using the above-mentioned rectangular folded steel plate, since the shape of the rectangular folded steel plate is determined, the shape of the rectangular folded steel plate cannot be changed according to the situation of the installation location at the construction site. . For this reason, the mounting position of the rectangular steel plate to the vertical member or the horizontal member is fixed, and there is a problem that the reinforcing metal fitting for building cannot be mounted when there is an obstacle at the mounting position.

  Accordingly, an object of the present invention is to provide a construction performance that can be reliably attached to a corner of a frame structure in which a vertical member and a horizontal member are joined at a right angle in a wooden or lightweight steel frame structure. An object of the present invention is to provide a construction hardware capable of adjusting an attachment position to a material according to the presence or absence of an obstacle.

  In order to solve the above-described problems, the reinforcing and quadrangular construction hardware of the present invention (hereinafter referred to as a combination hardware) is attached to a frame corner which is a joint between a vertical material such as a column and a horizontal material such as a beam. A vertical fixture fixed to the vertical member, a horizontal fixture fixed to the horizontal member, and the vertical fixture and the horizontal fixture so as to be rotatable at both ends. Are connected to a reinforcing member of a certain length, a shape holding member connected so that one end can be rotated to the center of the reinforcing member, and the other end of the shape holding member. It is composed of a right angle fixture that is arranged at a frame right angle portion that is connected so as to be rotatable, and the distance between the connection positions of both ends of the shape holding member is the connection position of both ends of the reinforcing member. It is formed to be half the distance between That.

  In addition, the vertical fixture includes an attachment material that is in contact with the vertical member and a joining plate provided with a bolt hole for connecting the reinforcing member, and the horizontal fixture is in contact with the horizontal member. A connecting plate provided with a bolt hole for connecting the mounting material and the reinforcing member, and the right angle fixture has a bolt hole for connecting the mounting material abutted on the frame right angle portion and the shape holding member. A bolt provided on the joining plate of the vertical fixture in a state where the reinforcing member and the shape-retaining member are attached to the inner surface of the corner of the frame via these fixtures. The horizontal distance between the hole and the mounting fixture of the vertical fixture, the vertical distance between the bolt hole provided on the horizontal fixture fixture and the mounting fixture of the horizontal fixture, and the bolt provided on the right fixture fixture The horizontal and vertical distances between the hole and the right-angle fixture attachment are all equal. As such, it is characterized in that the vertical fixture and horizontal fixture perpendicular fastener is formed.

  According to the dual-purpose hardware of the above configuration, it can be attached to the frame corner using the reinforcing member and shape-retaining member formed separately, and horizontal, vertical, and right-angle fixtures. It is not necessary to process to a long length and shape, and the labor and time of construction can be reduced.

  In addition, the connection between the reinforcing member, shape retaining member, and vertical, horizontal, and right-angled fixtures can be rotated, so that the fixing position of the horizontal and vertical fixtures on the inner side of the frame corner can be adjusted arbitrarily. can do. Therefore, when there is an obstacle around the vertical member or the horizontal member, the horizontal fixture and the vertical fixture can be fixed at a position avoiding the obstacle, and the combined hardware can be attached.

  Furthermore, since the shape holding member is formed so that the distance between the connection positions at both ends is half the distance between the connection positions at both ends of the reinforcing member, the shape holding member can be arbitrarily attached to the reinforcement member. Even if it is turned, the shape connecting the connection position of both ends of the reinforcing member and the connection position of the shape holding member connected to the right angle fixing tool is the one connected to the right angle fixing tool of the shape holding member The connecting position is always a right-angled triangle having a right-angled apex, and can be securely fixed to the corner of the frame where the vertical and horizontal members are joined at a right angle.

  As described above, according to the dual-purpose hardware according to the present invention, in a wooden or lightweight steel frame structure, a reinforcing member, a shape holding member, and horizontal, vertical, and right angle fixtures that are separately formed are used. Since it can be attached to the corners of the frame, it is not necessary to process the reinforcing material into the required length and shape at the construction site, and the construction effort and time can be reduced. In addition, since the fixing position of the horizontal and vertical fixtures on the inner surface of the frame corner can be adjusted arbitrarily, avoid obstacles when there are obstacles around the vertical and horizontal members. It is possible to fix the horizontal fixture and the vertical fixture in the above position and attach the combined hardware.

  Further, since the shape holding member is formed so that the distance between the connection positions at both ends is half the distance between the connection positions at both ends of the reinforcement member, the shape holding member can be arbitrarily rotated with respect to the reinforcement member. Even if it is moved, the shape connecting the connection position of both ends of the reinforcing member and the connection position of the shape holding member connected to the right angle fixing tool is the one connected to the right angle fixing tool of the shape holding member. The connecting position is a right-angled triangle having a right-angled apex, and it can be securely fixed to the corner of the frame where the vertical member and the horizontal member are joined at a right angle. In addition, when constructing a shaft frame, it is possible to form a frame in which a vertical member and a horizontal member are joined at right angles by attaching a dual-purpose hardware to the corner of the frame without checking the verticality of the vertical member. The material can be reliably installed vertically.

Is formed.

  Using the vertical fixture 4, the horizontal fixture 5, the reinforcing member 6, the shape-retaining member 7, and the right-angle fixture 8 configured as described above, the vertical metal 2 and the horizontal material 3 are joined at a right angle to the combined hardware 1. An example of a procedure for constructing the corner of the frame will be described below.

  First, the vertical fixture 4, the horizontal fixture 5, the reinforcing member 6, the shape holding member 7, and the right angle fixture 8 constituting the dual-purpose metal fitting 1 attached to the corner of the frame are connected to each other.

  The reinforcing member 6 uses two angle steels 6a and 6b as shown in FIG. 2, and the shape maintaining member 7 uses one flat plate as shown in FIG. As shown in FIG. 10, the reinforcing member 6 and the shape retaining member 7 are connected by arranging two angle steels 6a and 6b so that the outer surface sides of one of the flange portions face each other, and at the center of the angle steels 6a and 6b. At the position of the provided bolt holes 9b, 9b, one end of the flat plate of the shape retaining member 7 is inserted between the two angle steels 6a, 6b, and the bolt provided in the center of the angle steel 6a, 6b. The holes 9b, 9b and the bolt hole 10a provided at one end of the flat plate are overlapped, and the bolt 11 is inserted into the overlapped bolt holes 9b, 9b, 10a and tightened loosely. With this configuration, the shape maintaining member 7 is pivotally connected to the reinforcing member 6.

  Subsequently, the reinforcing member 6 and the vertical fixture 4 are connected by the bolt 11. At the position of the bolt holes 9a, 9a provided at one end of the two angle steels 6a, 6b constituting the reinforcing member 6, the joining plate 42 of the vertical fixture 4 is placed between the two angle steels 6a, 6b. The bolt holes 9a, 9a provided at one end of the angle steels 6a, 6b are overlapped with the bolt holes 421 provided in the joining plate 42, and the bolt holes 9a, 9a, The bolts 11 are inserted through 421 and tightened loosely. With this configuration, the vertical fixture 4 is pivotally connected to the reinforcing member 2.

  Next, the reinforcing member 6 and the horizontal fixture 5 are connected with bolts 11. At the position of the bolt holes 9c, 9c provided at the other ends of the two angle steels 6a, 6b constituting the reinforcing member 6, the joining plate 52 of the horizontal fixture 5 is provided between the two angle steels 6a, 6b. , And the bolt holes 9c, 9c provided at the other end of the angle steel 6a, 6b are overlapped with the bolt holes 521 provided in the joining plate 52, and the overlapped bolt holes 9c, The bolts 11 are inserted into 9c and 521 and tightened loosely. With this configuration, the horizontal fixture 5 is pivotally connected to the reinforcing member 2.

  Next, the shape holding member 7 and the right angle fixture 8 are connected by bolts 11. The bolt hole 10b of the shape holding member 7 not connected to the reinforcing member 6 and the bolt hole 821 provided in the joining plate 82 of the right angle fixture 8 are overlapped, and the bolt 11 is put on the overlapped bolt holes 10b and 821. Insert and tighten loosely. With this configuration, the right angle fixture 8 is pivotally connected to the shape holding member 7.

  At this time, the reinforcing member 6, the shape holding member 7, the vertical fixture 4, the horizontal fixture 5 and the right angle fixture 8 are all connected in a rotatable manner. Here, since the distance between the bolt hole 9b provided in the center of the reinforcing member 6 and the bolt holes 9a and 9c at both ends is equal to the distance between the bolt holes 10a and 10b at both ends of the shape maintaining member 7, According to the theorem, even if the shape holding member 7 is arbitrarily rotated with respect to the reinforcing member 6, the bolt holes 9a and 9c at both ends of the reinforcing member 6 and the right angle fixture 8 of the shape holding member 7 are connected. The shape of connecting the bolt hole 10b is always a right triangle with the bolt hole 10b at the right apex.

  The vertical fixture 4, the horizontal fixture 5, the reinforcing member 6, the shape holding member 7, and the right angle fixture 8 connected as described above are connected to the frame corner where the vertical member 2 and the horizontal member 3 are joined. Install.

  First, the attachment member 41 of the vertical fixture 4 is positioned so as to abut on the frame inner side surface of the vertical member 2. As shown in FIG. 1, the attachment position of the attachment member 41 of the vertical fixture 4 is preferably determined by an angle at which the reinforcing member 6 forms 45 degrees with respect to the vertical member 2 and the horizontal member 3. As shown in FIG. 11, when the obstacle 12 exists, the attachment position of the vertical fixture 4 is arbitrarily determined so as to avoid the obstacle 12. Then, the bolt 13 is inserted into the bolt hole 411 of the mounting member 41 to fix the mounting plate 41 to the vertical member 2.

  Subsequently, the rectangular folding attachment material 81 of the right-angle fixture 8 is brought into contact with the inner surface of the right-angle portion of the frame where the vertical member 2 and the horizontal member 3 are joined at a right angle.

  Here, since the positions of the vertical fixture 4 and the right angle fixture 8 are determined, the mounting position of the mounting member 51 of the horizontal fixture 5 on the horizontal member 3 is naturally determined. Then, the bolt 13 is inserted into the bolt hole 511 provided in the mounting member 51 of the horizontal fixture 5 to fix the mounting member 51 to the horizontal member 3.

  Finally, all the bolts 11 and 13 are firmly tightened. Through the above operation, the vertical fixture 4, the horizontal fixture 5, the reinforcing member 6, the shape holding member 7, and the right angle fixture 8 are all connected, and the construction of the combined hardware 1 is completed.

  The dual-purpose hardware 1 attached to the corner of the frame includes the horizontal distance between the bolt hole 421 provided in the joining plate 42 of the vertical fixing tool 4 and the mounting material 41 of the vertical fixing tool 4, and the joining plate 52 of the horizontal fixing tool 5. The vertical distance between the bolt hole 521 provided in the mounting member 51 of the horizontal fixing tool 5 and the horizontal distance between the bolt hole 821 provided in the joining plate 82 of the right-angle fixing tool 8 and the mounting material 81 of the right-angle fixing tool 8. All vertical distances are equal. Therefore, even if the shape holding member 7 is arbitrarily rotated with respect to the reinforcing member 6, the attachment member 41 of the vertical fixture 4, the attachment member 51 of the horizontal fixture 5, and the attachment member 81 of the right angle fixture 8 are vertical. The material 2 and the horizontal material 3 can be attached in contact with the inner surface of the frame corner where the material 2 and the horizontal material 3 are joined at right angles.

  According to the dual-purpose hardware 1 having the above-described structure, the reinforcing member 6 and the shape-retaining member 7 that are formed separately from each other and the horizontal, vertical, and right-angle fixtures 4, 5, and 8 can be attached to the frame corner. In addition, it is not necessary to process the reinforcing material into the required length and shape at the construction site, and the labor and time of construction can be reduced.

  In addition, since the connection between the reinforcing member 6, the shape holding member 7, and the vertical, horizontal, and right angle fixtures 4, 5, and 8 is rotatable, the horizontal fixture 4 and the vertical fixture on the inner side of the frame corner are fixed. The fixing position of the tool 5 can be adjusted arbitrarily. Therefore, when there is an obstacle 12 around the vertical member 2 or the horizontal member 3, the horizontal fixture 4 and the vertical fixture 5 are fixed at a position avoiding the obstacle 12, and the combined hardware 1 can be attached. it can.

  Furthermore, since the shape holding member 7 is formed such that the distance between the bolt holes 10a and 10b at both ends is half the distance between the bolt holes 9a and 9c at both ends of the reinforcing member 6, the shape holding member 7 The bolt holes 9a and 9c at both ends of the reinforcing member 6 are connected to the bolt holes 10b connected to the right angle fixing tool 8 of the shape maintaining member 7 even if it is arbitrarily rotated with respect to the reinforcing member 6. The shape is always a right triangle in which the bolt hole 10b is a right apex, and the vertical member 2 and the horizontal member 3 can be securely fixed to the corners of the frame where they are joined at a right angle. In addition, when the shaft frame is constructed, the vertical member 2 and the horizontal member 3 are joined at a right angle by attaching the dual-purpose hardware 1 to the corner of the frame without checking the verticality of the vertical member 2. It can be formed, and the vertical member 2 can be reliably applied vertically.
