  However, if there is a gap between the intervention piece and the wall part of the building and between the intervention piece and the floor part of the building, the intervention piece cannot be firmly fixed to the building, and it is attached on the intervention piece. Refractory materials and other construction materials that are produced sometimes shift over time.

  In order to solve the above-mentioned problem, in the interlayer support tool of the present invention, in the support tool attached to the gap between the wall portion of the building and the floor portion of the building, the upper surface placed on the upper surface of the floor portion. And a drooping portion that hangs down from the upper surface portion into the gap, and a drooping direction of the drooping portion forms an angle of 85 degrees to 65 degrees with respect to the upper surface portion, A floor projection provided in the middle and projecting toward the side surface of the floor portion in the gap, and a wall projection projecting toward the wall portion in the gap from below the hanging portion or the projection. Prepared.

  As a result, the floor protrusion comes into contact with the side surface of the floor portion, the wall protrusion comes into contact with the wall portion, and the insertion tool is closely attached and firmly fixed in the gap between the wall portion and the floor portion. . Also, the angle between the hanging portion and the upper surface portion is smaller than 90 degrees, the force that elastically spreads the hanging portion and the upper surface portion, and the force that the floor protruding portion protrudes and the entire hanging portion is elastically curved. Is a relationship that cooperates synergistically with each other, and is not a relationship that cancels each other, so that the support tool is in close contact with the inner surface of the gap, and the support tool is firmly fixed in the gap.

The whole side surface of the intervention tool 1 is shown. The whole external appearance of the intervention tool 1 is shown. The state in which the intervention tool 1 is slightly deformed and attached in the gap 53 between the wall panel 51 and the floor slab 52 is shown. The other embodiment of the intervention tool 1 is shown. The other embodiment of the intervention tool 1 is shown. The other embodiment of the intervention tool 1 is shown. The other embodiment of the intervention tool 1 is shown. The other embodiment of the intervention tool 1 is shown.

(1) Structure of the insertion tool 1 FIGS. 1 and 2 show the entire side surface and overall appearance of the insertion tool 1 of the present invention. The support tool 1 (interlayer support tool) is attached to a gap 53 between a wall panel 51 (wall portion) of a building and a floor slab 52 (floor portion) of the building. The wall panel 51 and the floor slab 52 are connected and fixed by a connecting fitting for construction (not shown). Such a gap 53 is formed due to structural necessity in, for example, a high-rise building.

  The support tool 1 is made of metal, for example, stainless steel, and has a thickness of 0.3 mm to 1.5 mm, for example, 0.7 mm, and has a uniform thickness as a whole. 3, a floor protrusion 4 and a wall protrusion 5. Since these hanging parts 3 of the intervention tool 1 are made of metal, they can be elastically deformed.

  The upper surface portion 2 at the upper end of the intervention tool 1 is a flat plate having a substantially square shape of 100 mm × 50 mm, and is placed almost horizontally on the upper surface of the floor slab 52 facing the gap 53.

  The drooping portion 3 integrally connected to the upper surface portion 2 is a vertically long rectangular flat plate of 100 mm × 110 mm, and has an angle of 85 ° to 65 °, for example, 80 ° with respect to the upper surface portion 2. It is bent and hangs substantially vertically on the gap 53. As a result, the drooping direction of the drooping portion 3 makes an angle of 85 degrees to 65 degrees with respect to the upper surface portion 2, for example, 80 degrees.

  Below the drooping portion 3, the floor protruding portion 4 is formed by bending toward the upper surface portion 2, that is, toward the side surface of the floor slab 52. The floor protrusion 4 is a horizontally long flat plate shape of 100 mm × 20 mm, and the protrusion direction of the floor protrusion 4 is an angle of 120 to 170 degrees with respect to the hanging portion 3. For example, it is bent obliquely downward at an angle of 150 degrees.

  The total length of the hanging portion 3 and the floor protrusion 4 is 5% to 25% shorter than the thickness of the floor slab 52 or 5 mm to 25 mm shorter than the thickness of the floor slab 52. Thereby, the intervention tool 1 does not protrude from the gap 53, and the appearance of the interior of the building can be made beautiful.

  For example, the length (height) of the drooping portion 3 is shorter than the thickness of the floor slab 52 by several tens of millimeters, for example, 30 millimeters. The height in the vertical direction of the floor protrusion 4 is approximately 20 millimeters / 2 × route (3) = 17.32 millimeters. The route (3) means the square root of “3”.

  Therefore, the total length of the drooping portion 3 and the floor protrusion 4 is shorter than the thickness of the floor slab 52 by 30 millimeters-17.32 millimeters = 12.68 millimeters. Since the thickness of the floor slab 52 is 110 millimeters + 30 millimeters = 140 millimeters of the drooping portion 3, it is shortened by 12.68 millimeters ÷ 140 millimeters = 9%.

  Below the floor protrusion 4, a wall protrusion 5 is formed by bending at an acute angle toward the direction opposite to the upper surface 2, that is, toward the floor slab 52. The wall protrusion 5 is 100 millimeters × 85 millimeters, or longer than the width of the gap 53 by 5 to 25 millimeters, for example, 10 millimeters.

  The wall protruding portion 5 is a vertically long, rectangular flat plate, and the protruding direction of the wall protruding portion 5 is an angle of 0 to 120 degrees with respect to the floor protruding portion 4, for example, an angle of 60 degrees. And bent toward the wall panel 51 in, for example, a substantially horizontal direction in a direction parallel to the upper surface portion 2.

(2) Attached instrument 1
FIG. 3 shows a state in which the intervention tool 1 is attached in the gap 53 with some deformation. The dimensions of the upper surface portion 2, the hanging portion 3, the floor protruding portion 4, and the wall protruding portion 5 of the intervention tool 1 are changed according to the thickness of the floor slab 52 and the width of the gap 53. At this time, the tip of the length of the wall protrusion 5 may be cut according to the width of the gap 53 at the construction site.

  The height of the gap 53 is the same as described above, and the height of the gap 53, that is, the thickness of the floor slab 52 is 140 millimeters, and the width of the gap 53 is 75 millimeters. The length of the wall protrusion 5 is 0% to 30%, for example, 5% to 25% longer than the width of the gap 53 between the wall panel 51 and the side surface of the floor slab 52, or 0 mm or more than the width of the gap 53. 30 millimeters, for example 5 to 25 millimeters long.

  Thereby, both ends of the wall projecting portion 5 at the lower end of the intervention tool 1 are in contact with the side surface of the wall panel 51 and the side surface of the floor slab 52, so that the intervention device 1 is in close contact with the inner surface of the gap 53. Is firmly fixed to the gap 53. For example, since the length of the wall protrusion 5 is 85 millimeters, the length of the wall protrusion 5 is 13.3%, that is, 10 millimeters longer than 75 millimeters of the width of the gap 53.

  Since the wall protruding part 5 has a size larger than the width of the gap 53, the protruding direction of the wall protruding part 5 is about 30 degrees from the horizontal direction, that is, the direction parallel to the upper surface part 2, and the direction of the upper surface part 2. That is, it faces upward, in other words, the elevation direction.

  If the dimension of the wall protrusion 5 is changed, the protruding direction of the wall protrusion 5 can be changed from the horizontal direction (parallel to the upper surface 2) to about 50 degrees. If the length is about 5% or 5 mm, the wall protrusion 5 can be made substantially horizontal, that is, substantially parallel to the upper surface portion 2 by elastic deformation of the wall protrusion 5.

  In this way, the width and direction of the wall projection 5 of the intervention tool 1 can be adjusted in accordance with the width of the gap 53. Since a fire-protecting plate material 54 is placed on the wall projecting portion 5, for example, both edges of the fire-proof plate material 54, the side surface of the wall panel 51, and the floor slab 52 according to the dimensions of the fire-proof plate material 54. There is no gap between the side and fire / fire resistance is improved. And the refractory material 55 is engage | inserted above the clearance gap 53 in which the intervention tool 1 was attached, and fire prevention measures are taken.

  This fireproof plate 54 is long in the width direction of the intervention tool 1, that is, in the direction perpendicular to the drawing, and closes the gap 53 along the longitudinal direction. In addition, since the fireproof plate 54 is also inclined along the inclination of the wall projection 5, even if the width of the gap 53 changes due to an earthquake or the like, this change is absorbed, and the fireproof plate, The wall protruding part 5 and the insertion tool 1 are not easily deformed.

  Since the floor protrusion 4 protrudes toward the side surface of the wall panel 51, when the intervention tool 1 is mounted in the gap 53, the drooping portion 3 is elastically deformed and curved, and above the drooping portion 3 ( The back surface and the lower side (back surface) of the floor protrusion 4 are in strong contact with the side surface of the wall panel 51, the intervention tool 1 is in close contact with the inner surface of the gap 53, and the intervention tool 1 is firmly fixed to the gap 53. The back surface indicates the right side surface of the intervention tool 1 in FIGS.

  In addition, the hanging direction of the hanging part 3 is an angle of 85 to 65 degrees with respect to the upper surface part 2 and is an angle smaller than 90 degrees, so that when the intervention tool 1 is attached to the gap 53, the hanging part 3 And the upper surface portion 2 are elastically deformed and widened, the upper portion (back surface) of the drooping portion 3 and the upper surface portion 2 (back surface) are in strong contact with the corners of the floor slab 52, and the support tool 1 is a gap The intermediary tool 1 is firmly fixed to the gap 53.

  The angle formed by the hanging part 3 and the upper surface part 2 is smaller than 90 degrees, the force by which the hanging part 3 and the upper surface part 2 are elastically expanded, and the floor protruding part 4 protrudes so that the entire hanging part 3 is elastic. The force that is curved is a relationship that cooperates synergistically with each other, and is not a relationship that cancels each other, so that the support tool 1 is in close contact with the inner surface of the gap 53, and the support tool 1 is stronger with the gap 53. Fixed to.

  In addition, since the most protruding tip of the floor protrusion 4 is located at the lowest position of the intervention tool 1, the elastic deformation of the hanging part 3 and / or the floor protrusion 4 can be sufficiently extracted. The tool 1 is in close contact with the inner surface of the gap 53, and the intervention tool 1 is firmly fixed to the gap 53.

  The length of the floor protrusion 4 is shorter than the length of the drooping portion 3, that is, the length of the drooping portion 3 is longer than the length of the floor protrusion 4. Thereby, the elastic deformation of the support tool 1 is concentrated on the hanging part 3, the contact area of the back surface of the hanging part 3 with the side surface of the floor slab 52 is increased, and the helping tool 1 adheres to the inner surface of the gap 53. The intervention tool 1 is firmly fixed to the gap 53.

  The length of the floor protrusion 4 is shorter than the length of the wall protrusion 5. Thereby, when the intervention tool 1 is put into the gap 53 between the wall panel 51 and the floor slab 52, the floor protrusion 4 does not get in the way, and the intervention tool 1 can be attached smoothly.

  The length of the floor protruding portion 4 is shorter than the length of the upper surface portion 2, that is, the length of the upper surface portion 2 is longer than the length of the floor protruding portion 4. Thereby, the contact area of the upper surface portion 2 to the upper surface of the floor slab 52 is increased, the upper surface portion 2 is difficult to be detached from the floor slab 52, the support tool 1 is in close contact with the outer surface of the floor slab 52, and the support tool 1 is It is firmly fixed to the floor slab 52.
