Description

  The present invention relates to an outer wall fitting for standing an outer wall, and more particularly to an outer wall fitting and an outer wall joining method that can be adjusted while absorbing some errors.

2. Description of the Related Art Conventionally, there has been known a construction method in which a curtain wall type outer wall is erected using an outer wall panel prepared in advance at a factory.
Thus, when standing an outer wall using an outer wall panel, the framework of a house is formed, for example with a steel beam, a pillar, etc., and an outer wall is erected according to this framework.
At this time, it is necessary to connect the outer wall and the beam. For this reason, a hardware for connecting the outer wall and the beam is used.

Various kinds of hardware for connecting the outer wall and the beam have been developed and actually used (see, for example, Patent Document 1).
Patent Document 1 discloses a metal fitting for joining in which a support plate and an engagement fitting are attached to each other through a channel material so that an angle between the support plate and the engagement fitting is substantially a right angle.
In the metal object described in Patent Document 1, the engaging metal fitting is attached to the H steel as a beam, and the outer wall is fixed to the beam via the metal object by fixing the outer wall with the engaging metal fitting.

JP 2002-235395 A (pages 3 and 4; FIGS. 1 and 6)

However, the hardware of Patent Document 1 cannot cope with a case where the distance between the outer wall and the beam is slightly deviated.
For example, when building a house with a rahmen structure (see Fig. 6), which is an earthquake-resistant structure, the columns and beams are joined in close contact without play, so the distance between the outer wall and the beams is Susceptible to the accuracy of the foundation leg and the accuracy of the beam. That is, the difference between the distance between the outer wall and the beam cannot be absorbed by the play between the column and the beam.
For this reason, it is relatively difficult to adjust the column structure, and the inclination of the column tends to affect the outer wall.

  An object of the present invention is to solve each of the above-mentioned problems, and is less affected by the accuracy of the foundation column base and the beam, and easily disposes the outer wall to the rigidly-framed house frame. It is an object of the present invention to provide an outer wall bonding hardware and an outer wall bonding method.

According to the first aspect of the present invention, there is provided an outer wall joint hardware for disposing an outer wall on a frame of a house composed of a beam and a column, and the outer wall joint hardware is attached to the beam. A beam joint to be joined, an outer wall joint formed continuously from one side of the beam joint , and joined to the outer wall, and substantially from above the boundary line between the outer wall joint and the beam joint A second reinforcing member disposed so as to bridge the support member and the beam joint portion at a vertically rising support member and an inner corner formed by the support member and the beam joint portion; comprising at least, in the beam joint, the fixed member through-hole for passing a fixing member for fixing the beam is provided as a long-formed loose hole to a distance direction between the outer wall and the beam The beam joint is interposed between the beam and the beam joint. When the joint is attached to the beam via a hardware fixing member for attaching the joint to the beam, and the beam joint is stacked on the beam via the hardware fixing member, the long axis of the fixing hole through hole is , The longitudinal axis of the loose hole formed in the hardware fixing member is set to intersect substantially perpendicularly, the beam joint is fixed to the beam via the hardware fixing member, the outer wall joint is This is solved by projecting substantially horizontally from the beam and mounting and fixing a part of the lower end of the outer wall .

The above object is achieved according to the invention of claim 2, and the beam joint portion joined to the beam, is formed continuously substantially horizontally from one side of the beams joint, an outer wall joint portion joined to the outer wall A support member that stands substantially vertically from a boundary line between the outer wall joint portion and the beam joint portion, and an inner corner formed by the support member and the beam joint portion. And an outer wall for disposing the outer wall on a framework of a house composed of the beam and the pillar via an outer wall joint hardware provided with at least a second reinforcing member disposed so as to bridge In the joining method, a fixing member through hole for allowing a fixing member for fixing the beam to pass therethrough is provided as a loose hole formed long in the distance direction between the outer wall and the beam. And the beam joint is interposed between the beam and the beam joint. When the beam joint is stacked on the beam via a hardware fixing member for attaching the beam joint to the beam, the fixing hole through-hole is stacked when the beam joint is stacked on the beam via the hardware fixing member. The long axis is set so as to intersect the long axis of the metal member substantially perpendicularly, the loose hole formed in the hardware fixing member, and the beam joint along a part of the beam along the fixing hole through hole. A position adjusting step of moving the outer wall joint metal to a position where the outer wall joint is in contact with a part of the outer wall, the beam joint, and a part of the beam in contact with the beam joint. A beam fixing step of fixing by passing a fixing member through the fixing hole through hole and fixing, and an outer wall fixing step of fixing the outer wall joint portion and a part of the outer wall in contact with the outer wall joint portion It is solved by doing.

In this way, the outer wall and the beam are fixed by the outer wall joint hardware having a loose hole at the beam joint.
This loose hole is formed long in the distance direction between the outer wall and the beam.
Therefore, the arrangement position of the outer wall joint hardware can be adjusted by the length of the loose hole.
For this reason, even when the column and beam are rigidly joined in close contact with no play, the error in the distance between the outer wall and the beam can be adjusted. Less sensitive to accuracy.

  At this time, the outer wall joint portion is formed substantially continuously from one side of the beam joint portion, and the beam joint portion is fixed to the beam with the outer wall joint portion facing downward, It is preferable that the outer wall joint portion be fixed in a state of being pressed against the outer wall because the beam joint portion and the lower end portion of the beam and the outer wall joint portion and the outer wall can be easily joined.

  Further, at this time, the outer wall joint portion is formed substantially continuously from one side of the beam joint portion, the beam joint portion is fixed to the beam, and the outer wall joint portion is formed of the beam. When projecting approximately horizontally and a part of the lower end of the outer wall is placed, the beam joint and the beam upper end can be easily joined, and the outer wall lower end can be easily placed in the outer wall joint. It is suitable because it can be bonded to the substrate.

Further, at this time, a first reinforcing member disposed so as to bridge the outer wall joint portion and the beam joint portion is attached to an inner corner portion formed by the outer wall joint portion and the beam joint portion. ing.
Further, at this time, a support member is disposed on the boundary line between the outer wall joint portion and the beam joint portion so as to stand substantially vertically from the boundary line, and is formed by the support member and the beam joint portion. In the inner corner portion, a second reinforcing member is provided so as to bridge the support member and the beam joint portion.
Therefore, the outer wall joining hardware is reinforced, and the beam and the outer wall can be joined with high strength, which is preferable.

According to the present invention, the outer wall and the beam are fixed by the outer wall joint hardware having a loose hole at the beam joint.
This loose hole is formed long in the distance direction between the outer wall and the beam.
Therefore, the arrangement position of the outer wall joint hardware can be adjusted by the length of the loose hole.
In general, when constructing a house with a rigidly-framed structure in which the columns and beams are in close contact with each other without any play, the play between the columns and the beams will reduce the distance between the outer wall and the beams. The error cannot be absorbed.
For this reason, it is relatively difficult to adjust the column structure, and the inclination of the column tends to affect the outer wall.
However, according to the outer wall fitting according to the present invention, the fixing member (for example, bolt) through-hole for joining the outer wall fitting and the beam is formed as a loose hole, so that the column and the beam are rigidly joined. Even in such a case, the error in the distance between the outer wall and the beam can be adjusted.
Therefore, it becomes difficult to be influenced by the accuracy in the foundation leg and the accuracy of the beam.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
Note that the configuration described below does not limit the present invention and can be variously modified within the scope of the gist of the present invention.
The present embodiment relates to an outer wall joint hardware that is less affected by the accuracy of the foundation column base and the beam and can easily dispose the outer wall with respect to a rigidly-framed house frame.

Therefore, even if the distance m between the frame S2 of the outer wall S and the beam T slightly changes depending on the accuracy of the foundation column base or the beam, the outer wall S can be easily disposed by absorbing the distance change.
As a mounting procedure of the second outer wall joint hardware 20, the second outer wall joint hardware 20 is moved between the heat insulating material S3 and the beam T, and the end side of the outer wall mounting portion 22A (the long side of the second vertical plate portion 21) is moved. And the side facing the frame S2 is disposed at a position where it is in pressure contact with the frame S2. This process corresponds to a position adjustment process.
At this time, in order to reinforce the gap n formed between the hardware fixing member 30 and the second outer wall bonding hardware 20, a gap reinforcing member 40 (thickness is the thickness of the gap n) is a substantially rectangular plate. (Same as the width) is disposed in the gap n. The gap reinforcing member 40 is also the same member as that used when the outer wall S and the beam T are joined by the first outer wall fitting 10.

For this reason, the bolts B5 and B5 are fixed through the joint hardware fixing portion 30a, the gap reinforcing member 40, and the second hardware second bolt holes 22a and 22a.
In this way, the second outer wall bonded hardware 20 is attached to the beam T via the hardware fixing member 30.
