Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a construction brace member for reinforcing a small dance wall foundation, for example.

[0002]

[Prior art]

 The wall of a wooden house is made of a thin wooden or bamboo small dance, and is reinforced with bracing members consisting of a pair of left and right turnbuckles with a flange nut in the center. The material is painted and manufactured.

In this case, a brace member conventionally used as a reinforcement for a small dance wall foundation is such that the screw rods are respectively fed into the screw holes provided in the flange flange nut from both directions, and the other end of the screw rod is connected to the turnbuckle. The screw rod provided at one end is configured to be fed into a screw tube having a blind end, and in use, the threaded rod is rotated by rotating the central flange nut in one direction or the opposite direction. By advancing or retracting the screw pipe formed in the turnbuckle or the screw hole formed in the flange nut, the wall base constructed by expanding and contracting to make a small dance is reinforced.

[0004]

[Problems to be solved by the device]

 However, in the conventional brace member as described above, the screw rod is inserted into the screw hole of the flange flange nut from both directions, and the tip end of the screw tube provided in the turnbuckle is blind. The range in which the screw rod can move in and out of the screw tube or the screw hole by the rotation of the nut is limited, and therefore, the range in which the brace members are expanded and contracted is also limited. Therefore, the base area that can be reinforced is also limited.

When the conventional brace members are placed on a wall foundation constructed by combining small dances, both ends of the brace members can be locked to the four corners of the foundation, but the middle portion is the foundation. Since it is not fixed to the brace, the reinforced brace member becomes unstable and a sufficient reinforcement effect cannot be achieved.

[0006]

[Means for Solving the Problems]

 In order to solve the above problems, according to the present invention, a pair of turnbuckles having a screw tube with an open end at one end thereof, a tab flange nut having screw holes opened at both ends thereof, and a screw tube of the turnbuckle are provided. And a pair of screw rods screwed into the screw holes of the tab flange nuts, and the bolt rods are screwed into the screw holes of the tab flange nuts from both directions orthogonal to the screwing direction of the screw rods. At least one of the bolt rods proposes a structural brace member with its head shaped like a key.

[0007]

[Action]

 In other words, in this invention, the screw tube provided in the turnbuckle has an open end, so that when the flange nut is rotated, the screw rod is not limited to the length of the screw tube and moves in and out of the screw tube. Therefore, in the present invention, by using a long screw rod, it is possible to provide a construction bracing member with unlimited expansion and contraction.

Further, according to the present invention, the bolt rod is screwed into the screw hole of the flange nut from both directions orthogonal to the screwing direction of the screw rod, so that the screw rod fed into the screw hole is Can be securely fixed.

Further, in this invention, at least one of the bolts has a key-shaped head, and therefore the key-shaped head is hooked on a small dance forming the base to position the brace member. can do.

In this case, by making the heads of the bolts arranged symmetrically in the left-right direction, the brace members can be positioned more stably when hooked on a small dance.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will now be described in detail with reference to the illustrated embodiments. 1 is a brace member according to the present invention, 2a and 2b are a pair of turnbuckles, and one end of the turnbuckle 2a has its tip. A screw tube 3a having an open end is provided, and the corresponding turnbuckle 2b is provided at one end thereof with a screw tube 3b having an open tip and having a screw groove formed in the opposite direction to the screw tube 3a.

Reference numeral 4 is a flange flange nut having a bolt tightening hole 5 in its center, and both ends of the flange flange 4 are provided with screw holes 6a and 6b in which screw grooves are formed in opposite directions.

Reference numerals 7a and 7b denote a pair of screw rods that connect the turnbuckle 2a and the tab flange nut 4, and the tablang nut 4 and the turnbuckle 2b. The screw rod 7a is screwed to the screw tube 3a and the screw hole 6a to form a screw. The rod 7b is screwed into the screw hole 6b and the screw tube 3b.

On the other hand, bolt rods 8a and 8b are screwed into the screw hole 6a from both directions orthogonal to the screwing direction of the screw rod 7a, and the screw hole 6b is orthogonal to the screwing direction of the screw rod 7b. The bolt rods 8c and 8d are screwed in from both directions, and the heads of the bolt rods 8a and 8d at the symmetrical positions are a key-shaped head 9a and a key-shaped head 9d.

The brace member 1 includes a screw rod 3a provided on the turnbuckle 2a and a screw rod 7a screwed into a screw hole 6a formed on the flange nut 4, and a screw pipe 3b provided on the turnbuckle 2b and a flange. The screw rod 7b is screwed into the screw hole 6b formed in the nut 4, the tough flange nut 4 is rotated in one direction to adjust its length, and further the bolt rods 8a, 8b, 8c, 8d are screwed in to screw the screw. Fix the rods 7a and 7b.

Next, an example of use of the brace members 1 will be described with reference to FIG. 3. FIG. 3 shows a wall surface of a wooden house, and 10 and 10 are recumbent members provided at the upper and lower ends of the wall surface, 11,11 are pillar materials provided on both sides of the wall surface, 12, ... are small bamboo dances that compose the foundation of the wall surface, and penetrating materials 13, ... are passed between the pillar materials 11 and 11. On the other hand, the brace members 1 and 1 are fixed to the four corners of the wall surface where the column members 11 and the recumbent members 10 intersect with the lock members 14.

As shown in FIG. 4, the lock member 14 includes bolts 15 and 15 screwed into the pillar member 11, fixed with nuts 17 and 17 via washers 16 and 16, and the bolts 18 and 18 are laid down. Fix it by screwing it into the material 10.

On the other hand, the lock member 14 and the end portion of the brace member 1 are coupled via a washer. The number of washer is the same as that of the lock member 14 for adjusting the distance between the penetrating member 13 and the brace member 1. It is interposed between the brace members 1.

The brace members 1, 1 arranged on the wall surface are adjusted to have an appropriate length to reinforce the wall surface by rotating the tab flange nut 4, but in the present invention, screws provided on the turnbuckles 2a, 2b. Since the pipes 3a, 3b are open at their tips, when the flange nut 4 is rotated, the screw rods 7a, 7b move in and out of the screw pipe without being restricted by the length of the screw pipe. It can be adjusted to a length suitable for reinforcing the wall.

After that, the bolt rods 8a, 8b, 8c, 8d are screwed in to fix the screw rods 7a, 7b, and the key-shaped heads 9a and 9d of the bolt rods 8a and 8d are hooked on the Komai 12, 12. The brace member 1 is positioned.

In this embodiment, elongated holes 19, ... Are provided along the longitudinal direction of the brace member 1. When the elongated hole 19 and the penetrating member 13 intersect, the nail 20 is passed through the elongated hole 19. The head of the nail 20 is hooked on the penetrating member 13 to more stably install the bracing member 1 on the wall surface.

[0022]

[Effect of device]

 In summary, according to the present invention, the length of the brace members can be freely adjusted, so that it can be used to reinforce wall surfaces of various sizes.

In addition, since the bolt rod is screwed into the screw hole of the flange flange nut from both directions orthogonal to the screwing direction of the screw rod, and at least one of its heads is keyed, For example, it can be reliably installed on a wall surface using Komai as the base.
