Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a method for attaching a protruding corner member formed of an inorganic material to an external wall attachment member.

[Background technology] When attaching a corner member made of an inorganic material such as cement or asbestos cement to an external wall mounting member, conventionally, the end of a mounting groove that is provided along the entire length in the longitudinal direction on the inside corner side of the corner member is The locking protrusion of the fixture was inserted into the mounting groove, and the fixture was then fixed to the outer wall mounting member. Therefore, there is a drawback that it requires a great deal of effort to insert the locking protrusion of the fixture from the longitudinal end of the mounting groove.

[Object of the Invention] The present invention was invented in view of the above points, and its object is to attach a fixing metal fitting to a mounting groove having a locking recess at the bottom provided on the inner corner side of a corner member. The locking protrusion of the fixture can be inserted from the opening end in the width direction of the mounting groove, and the locking piece of the locking protrusion can be locked in the locking recess at the bottom of the mounting groove. Although it is possible to easily fit the corner member into the mounting groove of the corner member with one touch, and the locking protrusion can be inserted into the locking recess from the front side of the corner member to lock it, the corner member Even if only one piece is fixed with a fixing bracket, the corner member can be installed to prevent it from moving laterally, and the head of the fixing bracket that fixes the fixing bracket attached to the corner member to the external wall mounting member can be attached to the corner member. To provide a method for attaching a protruding corner member that can be hidden by a connecting external wall panel.

[Disclosure of the Invention] The method for attaching an out-corner member of the present invention is to provide a locking recess 2 at the bottom of an in-corner side surface of a corner member 1 formed of an inorganic material and having a substantially L-shaped cross section, the bottom being wider on the bottom side than the open end. A pair of locking protrusions 5 having a substantially L-shaped cross section are provided upright from the substantially plate-shaped fixture 4 so as to face each other. The protruding directions of the locking pieces 7 at the tips of the pair of locking protrusions 5 are opposite to each other, and after inserting the locking pieces 7 at the tips of the pair of locking protrusions 5 from the front side of the mounting groove 3 into the depths of the groove, the corner member is removed. Rotate the fixing fittings 4 by 90 degrees with respect to 1 to lock the locking pieces 7 in the locking recesses 2, respectively, and the protruding pieces 6 at the base of the locking projection 5.
A fixing tool 10 is inserted into the mounting groove 3 and inserted into the outer wall mounting member 9 through a mounting hole 8 drilled in a portion of the fixing member 4 that protrudes outward from the inner corner side of the corner member 1.
The corner member 1 is fixed at the corner member 1, and by adopting such a configuration,
The above-mentioned object of the present invention has been achieved.

The present invention will be explained in detail below with reference to Examples. The corner member 1 for forming the protruding corner of the outer wall of the building is made of cement, concrete, asbestos cement,
It is made of inorganic material such as glass fiber reinforced cement, and has an approximately L-shaped cross section that is long in the vertical direction.
Two mounting grooves 3 extending substantially over the entire length in the longitudinal direction are spaced apart from each other in the width direction on both surfaces of the corner member 1 on the inside corner side. 2 on one side of the inside corner of corner member 1
The two mounting grooves 3 are provided at symmetrical positions with respect to the two mounting grooves 3 on the other surface and the corners of the corner member 1, and the bottom side of each mounting groove 3 has a locking groove recessed outward in the width direction. The recess 2 is recessed over substantially the entire length, and each mounting groove 3 is wider at the bottom than at the open end due to the locking recess 2. Also corner member 1
A joining protrusion 11 is provided at the outer end of both surfaces on the inside corner side thereof, protruding over substantially the entire length in the longitudinal direction. The metal fixture 4 has a substantially rectangular plate shape, and a pair of locking protrusions 5 consisting of an outer locking protrusion 5a and an inner locking protrusion 5b are protruded from each other. There is. That is, an outer locking protrusion 5a is provided at the center of one end of the fixture 4, and an inner locking protrusion 5b is provided at the center of the fixture 4 to face each other. The locking pieces 7 of the locking protrusions 5a and 5b protrude in opposite directions, and both corner portions at the tip of each locking piece 7 are chamfered portions 13 each chamfered in an arc shape. The inner and outer locking protrusions 5a, 5b are composed of a protruding piece 6 serving as a protruding base and a locking piece 7 protruding from the tip of the protruding piece 6 toward the mounting hole 8, and have a substantially L-shaped cross section. The width of each locking piece 7 is slightly smaller than the opening end of the mounting groove 3. A plurality of mounting holes 8 are bored on the other side of the fixture 4. Therefore, when attaching the fixing bracket 4 to the corner member 1, as shown in FIG. is rotated 90 degrees in the direction of arrow B, and each locking piece 7 is inserted and locked into the opposing locking recess 2, respectively. Even in the above embodiment, each locking piece 7 is inserted into the mounting groove 3 by simply rotating the fixing bracket 4 by 90 degrees after inserting the locking protrusions 5a and 5b into the mounting groove 3 from the open end of the mounting groove 3. 3. Since it is inserted and locked into the locking recesses 2 on both sides, the locking protrusions 5a of the fixture 4,
5b into the mounting groove 3 and attaching the fixing fitting 4 to the corner member 1 is easy. Furthermore, since chamfered portions 13 are provided at both corners of the tip of each locking piece 7, each locking piece 7 can be locked by easily rotating the fixture with the locking protrusions 5a and 5b inserted into the mounting groove 3. It can be inserted and locked into the recess 2. In the figure, 14 is a pillar.

As mentioned above, the locking protrusions 5a and 5b of the fixing metal fitting 4
After inserting each protruding piece 6 from the open end of the mounting groove 3 into the mounting groove 3 on the inside corner side of the corner member 1, each locking piece 7 is inserted by simply rotating the fixing bracket 4 by 90 degrees. Since the locking protrusions 5a and 5b of the fixture 4 are inserted and locked into the opposing locking recesses 2, it is easy to attach the locking protrusions 5a and 5b of the fixture 4 to the corner member 1. Since the outer wall panel 12 is joined to the joining protrusion 11 on the side of the member 1 along the outer wall mounting member 9, the head of the fixing tool 10 driven into the outer wall mounting member 9 through the fixing fitting 4 and the mounting hole 8 is It is hidden behind the outer wall panel 12 and cannot be seen from the outside.

[Effects of the Invention] Since the present invention has the above-described configuration, the locking protrusion of the fixing fitting is attached to the mounting groove having the locking recess at the bottom provided on the inner corner side of the corner member. Insert the fixing bracket from the open end in the width direction of the
The locking piece of the locking protrusion can be locked into the locking recess at the bottom of the mounting groove by simply rotating 90 degrees, and the locking protrusion of the fixing bracket can be easily fitted into the mounting groove of the corner member with one touch. In addition, even though the locking protrusion can be inserted into the locking recess from the front side of the corner member to lock the corner member, even if only one piece of the corner member is fixed with the fixing bracket, the corner The component can be installed so that it does not move laterally, and the head of the fixture that fixes the fixture attached to the corner component to the exterior wall mounting component can be hidden by the exterior wall panel that connects it to the corner component. .
