Description

  The present invention relates to a fixture for fixing an outer wall material of a building to a pillar material, a trunk edge material or the like, and also relates to a building outer wall structure and a building outer wall construction method using the fixture.

  Conventionally, the technique of improving the earthquake resistance performance and fireproof performance of a building with the outer wall material of a building is known, and there are documents that disclose this (for example, refer to Patent Document 1).

  Patent Document 1 proposes a technique for fastening an outer wall material of a building having earthquake resistance and fire resistance to a trunk edge using a fixing tool (fixing member) having a self-drilling tip at a tip. By using such a self-drilling fixture, the tip enters while removing (cutting) the material of the outer wall material, so that the outer wall material cracks during the fastening process, An increase in internal stress can be prevented. As a result, it is possible to improve the earthquake resistance and fire resistance.

JP2008-240266

  However, in the configuration disclosed in Patent Document 1, there is a concern that a gap may be formed between the fixture and the outer wall material. And invasion of the water from this clearance gap occurs, and there is a concern about the deterioration of the outer wall material due to this, and consequently the deterioration of earthquake resistance and fire resistance.

  That is, the fixture disclosed in Patent Document 1 having a self-drilling tip can be made of a metal such as stainless steel having “sufficient surface hardness to remove (cut) the outer wall material”. It is assumed that the seating surface of the head (bolt head) of the fixture also has the same surface hardness as other parts. And because of such surface hardness, the seating surface of the head does not follow the surface of the outer wall material, that is, the seating surface does not deform, so the uneven surface of the outer wall material cannot be absorbed, It is conceivable that a gap is formed between the seating surface and the uneven surface.

  On the other hand, the surface of the outer wall material is pressed by the seating surface of the head, so that the surface of the outer wall material deforms following the seating surface and the gap is absorbed. Since the stress concentrates locally in the deformed outer wall material, there is a concern that cracks may occur in the concentrated part due to aging.

  Further, since the fixing tool enters while removing (cutting) the outer wall material, it is assumed that so-called “swarf” is generated. And when fastening the fastener, if chips remain between the seating surface of the head and the surface of the outer wall material, the seating surface and outer wall of the head will also be affected by the presence of this chipping. There is a concern that gaps may be formed between the surfaces of the materials.

  On the other hand, in general bolt fastening, a washer is used to prevent loosening and protect the material surface. Even when such a washer is used, the material is metal. For this reason, the above-mentioned problems cannot be solved. Moreover, since the outer diameter of the washer is designed to be larger than the outer diameter of the head, there is a concern that the appearance design of the outer wall material may be impaired due to the presence of the washer.

  In view of the above problems, the present invention proposes a novel structure that can prevent the ingress of water from the gap between the fixture and the outer wall material with respect to the outer wall material fixture.

  FIG. 1 is a diagram illustrating a concept of fixing an outer wall member 20 using a fixture 10 according to an embodiment of the present invention. In the example of FIG. 1, windows 2, 2... And a front door 3 are provided at the opening of the building 1, and the exterior is configured so that other parts are covered with the outer wall materials 20 and 20. Yes. Further, the outer wall material 20 is fixed to a trunk edge (not shown) by the fixing tool 10.

  Moreover, FIG. 2 is a figure shown about the Example of the structure of the building frame 4 to which the outer wall material 20 is fixed. In the example of FIG. 2, a column 6 and an intermediate column 7 are arranged between the upper and lower beams 5, 5, and trunk edges 8, 8 are provided so as to straddle the column 6 and the intermediate column 7. A moisture permeable waterproof sheet 9 is disposed on the indoor side of the trunk edges 8 and 8, and an outer wall material 20 is disposed on the outdoor side of the trunk edges 8 and 8.

  In the example of FIG. 2, the outer wall material 20 is fixed to the trunk edge 8 or the stud 7 from the outdoor side by the fixtures 10 and 10, and the fixtures 10 and 10 are spaced at a predetermined interval. Appears on the exterior. Examples of the outer wall material 20 include ceramic siding, ceramic siding, and metal siding.

Next, the configuration of the fixture 10 will be described with reference to FIG.
First, as shown in FIG. 3A, the fixture 10 includes a shaft portion 15 in which a screw portion 14 having a tip 13 having a self-drilling shape is formed, and an end portion of the shaft portion 15 opposite to the tip 13. And a watertight member 16 disposed coaxially with the shaft portion 15 so as to surround the outer periphery of the shaft portion 15.

  Further, as shown in FIGS. 3A and 4A, in the shaft portion 15 of the fixture 10, the “self-drilling shape” which is the shape of the tip 13 is rotated in the axial direction while being rotated about the shaft center. By applying a load, it means a shape that can proceed while removing (cutting) materials such as the outer wall material 20 and the trunk edge 8, and examples thereof include the shape of a drill blade. Further, in the shaft portion 15, a screw portion 14 is formed continuously with the self-drilling shape of the tip 13, and the outer wall material 20 is fixed to the trunk edge 8 with the fixture 10 as shown in FIG. In the state, the screw portion 14 is coupled so as to mesh with the trunk edge 8, so that it does not come off from the trunk edge 8.

  Further, as shown in FIG. 3 (a), the material of the fixture 10 is not particularly limited, but is widely used as a material for bolts and screws, and is used for the outer wall material 20, the trunk edge 8, and the like. On the other hand, a material that is not damaged when twisted and has sufficient durability to maintain the fixation of the outer wall material 20 for a long period of time is preferable.

  Further, as shown in FIGS. 3A and 3B, the head 11 side of the shaft portion 15 of the fixture 10 is constituted by a cylindrical peripheral surface constituting portion 15a in which the screw portion 14 is not formed. The head 11 is continuously provided on the peripheral surface constituting portion 15a.

  Further, as shown in FIGS. 3A and 3B, an annular watertight member 16 is provided so as to surround the cylindrical circumferential surface constituting portion 15a. The watertight member 16 is made of an elastic material such as rubber, resin, or foam, and serves to prevent leakage of liquid or gas at the joint. In a state where the outer wall material is fixed in the shape, it is deformed so as to absorb the irregularities on the surface of the outer wall material, and the gap between the outer wall material and the head 11 of the fixing device 10 is closed to ensure water tightness. It is.

  Further, as shown in FIGS. 3A and 3B, a slight gap is formed between the watertight member 16 and the cylindrical circumferential surface constituting portion 15a, and the watertight member 16 moves in the axial direction of the cylindrical circumferential surface constituting portion 15a. It can be done. Further, the outer diameter d1 of the watertight member 16 is configured to be smaller than the outer diameter D1 of the head 11 of the fixture 10, and as shown in FIG. In this state, the watertight member 16 is hidden by the head 11.

  Moreover, as shown in FIG.3 (b), the head 11 of the fixing tool 10 has the seat surface 17 which forms a plane in the axial part 15 side. The seat surface 17 is formed with an annular groove 17a centering on the cylindrical peripheral surface constituting portion 15a, and the watertight member 16 is disposed so as to face the groove 17a. Further, the outer diameter d1 of the watertight member 16 is configured to be smaller than the outer diameter D2 of the outer peripheral contour 17b of the groove portion 17a. Further, the depth of the groove portion 17a (the axial dimension of the shaft portion 15) is set smaller than the thickness of the watertight member 16 (the axial dimension of the shaft portion 15), so that FIG. As shown in FIG. 4, in a state where the outer wall material 20 is fixed by the fixing tool 10, the watertight member 16 is sandwiched between the surface 21 of the exterior material 20 and the head 11 of the fixing tool 10. It has become so.

  Further, as shown in FIGS. 3B and 3C, the head portion 11 of the fixture 10 has a hemispherical front surface 18 on the side opposite to the shaft portion 15. A tool insertion hole 12 is formed on the front surface 18 on the axial center line of the cylindrical circumferential surface constituting portion 15a. The tool insertion hole 12 has a substantially square hole cross section. By using a tool corresponding to the shape of the hole cross section, the fixture 10 can be screwed into the outer wall member 20 or the trunk edge 8. It has become.

Next, fixation of the outer wall material 20 by the fixing tool 10 will be described with reference to FIG.
As shown in FIG. 4A, by using a tool (not shown), the tip 13 of the fixture 10 is brought into contact with the surface 21 of the outer wall material 20, and the fixture 10 is rotated while applying a load in the right direction. While the material of the outer wall material 20 is removed by the tip 13 of the fixture 10 and the cut hole 20a is formed, the fixture 10 advances in the right direction. And the front-end | tip 13 arrives at the trunk edge 8, and the fixing tool 10 advances rightward, while the material of the trunk edge 8 is removed and the cut hole 8a is formed.

  And as shown in FIG.4 (b), if the fixing tool 10 further advances to the right direction, the watertight member 16 will contact the surface 21 of the outer wall material 20, and if the fixing tool 10 further advances to the right direction from this state. As shown in FIG. 4C, the watertight member 16 is sandwiched (pressed) between the head 11 and the surface 21 of the outer wall member 20 so that the outer wall member 20 is fixed by the fixture 10. Completed.

  4A to 4C, since the distal end 13 of the fixture 10 has a self-drilling shape, the fixture 10 removes (cuts) the material while the outer wall material 20 and the trunk edge 8 are removed. Therefore, cracks are not generated in the process of fixing the outer wall material 20 by the fixing tool 10, and internal stress does not increase at a location where the fixing material 10 of the outer wall material 20 or the trunk edge 8 exists. . If there is a crack or a large internal stress at the location where the fixture 10 is present in the outer wall material 20, when the building is shaken during an earthquake or the like, the outer wall material 20 is cracked due to the crack or the internal stress. However, according to the configuration of the present embodiment, it is possible to prevent the occurrence of such cracks. In particular, when the outer wall material 20 has seismic performance and fireproof performance, it becomes possible to maintain reliable seismic performance and fireproof performance by preventing cracks. As a result, the material cost can be reduced by reducing the wall thickness, Costs can be reduced by eliminating the use of earthquake-resistant materials.

  Here, as shown in FIGS. 5A and 5B, the surface 21 of the outer wall material 20 has irregularities 22. The irregularities 22 may be regularly formed by a pattern provided on the surface 21 or may be randomly formed. In addition, since the fixture 10 enters while removing (cutting) the outer wall material 20, a so-called “cutting powder” is generated, and a situation in which irregularities are formed by the cutting powder is also assumed.

  Since the watertight member 16 has elasticity with respect to such irregularities 22, as shown in FIG. 5B, the watertight member 16 deforms along the irregularities 22, deforms so as to absorb the irregularities 22, and changes the surface 21. It adheres to. As a result, the gap between the watertight member 16 and the surface 21 is closed, water intrusion between the watertight member 16 and the surface 21 is prevented, and water enters the cut hole 20 a formed in the outer wall member 20. Intrusion can be reliably prevented. By preventing such water intrusion, it is possible to prevent deterioration of the outer wall material 20 and the trunk edge, and in turn, deterioration of earthquake resistance and fire resistance.

  Further, as shown in FIGS. 5A and 5B, the watertight member 16 has elasticity. Therefore, as shown in FIG. 5B, the watertight member 16 has a groove 17a formed on the head 11 of the fixture 10. It is deformed so as to enter and is in close contact with the surface 17c of the groove 17a. This closes the gap between the watertight member 16 and the surface 17c and prevents water from entering between the watertight member 16 and the surface 17c. Therefore, the outer wall material passes through the shaft portion 15 of the fixture 10. Thus, it is possible to reliably prevent water from entering the cut hole 20a formed in the hole 20. By preventing such water intrusion, it is possible to prevent deterioration of the outer wall material 20 and the trunk edge, and in turn, deterioration of earthquake resistance and fire resistance.

  Moreover, as shown in FIG.3 (b), the outer diameter d1 of the watertight member 16 is comprised smaller than the outer diameter D2 of the outer periphery outline 17b of the groove part 17a. As a result, as shown in FIG. 5 (b), when the watertight member 16 is deformed so as to enter the groove portion 17a and is crushed between the groove portion 17a and the surface 21 of the outer wall member 20 to increase the outer diameter d1. The watertight member 16 is housed in the groove portion 17a. That is, the watertight member 16 is stored inside the outer periphery of the head 11 by the groove portion 17a. Thus, the watertight member 16 does not protrude from the head 11 and does not appear in the appearance.

  And according to the above structure, as shown in FIG. 1, since the watertight member 16 does not appear in an external appearance, only the head 11 of the fixing tool 10 will be arrange | positioned in the outer wall material 20, Therefore In an external appearance, it is useless. It becomes possible to construct a simple appearance design in which no members appear and no rough impression is given.

  In addition, as shown in FIG. 1, with respect to the appearance design, the tool insertion hole 12 of the fixture 10 has a substantially square hole cross section, so that a cross or hexagonal tool insertion employed for a general screw is used. It is possible to configure a square-shaped appearance design different from the hole. Here, in the case of the fixture 10 of the present embodiment, it is necessary to transmit a large torque to the head 11 in order to enter the outer wall material 20 while removing (cutting), and the tool insertion hole 12 is sufficiently large. It is necessary to ensure. In the case of a tool insertion hole showing a general cross-shaped appearance, if the tool insertion hole is configured to be large, the impression that it is a very general screw will be noticeable. On the other hand, if the square shape is used as in the present embodiment, the design can be exhibited even by the square shape, and it is possible to combine design and functionality (torque transmission). is there.

With the above configuration, the present invention can be implemented.
That is, as shown in FIGS.
A fixing tool 10 for fixing the outer wall material 20 to a building frame (beam 5, column 6, space column 7, trunk edge 8, etc.),
The fixture 10 is
A shaft portion 15 on which a screw portion 14 having a tip 13 having a self-drilling shape is formed;
A head portion 11 formed at an end portion of the shaft portion 15 opposite to the tip end 13;
A watertight member 16 disposed coaxially with the shaft 15 so as to surround the outer periphery of the shaft 15;
Have
The watertight member 16 has elasticity, and is sandwiched between the seating surface 17 of the head 11 and the outer wall member 20 to be elastically deformed.

Further, the seat surface 17 of the head 11 has a groove portion 17 a for accommodating the elastically deformed watertight member 16 inside the outer periphery of the head 11 in a state where the watertight member 16 is sandwiched. It is what.

  Thereby, in the state which fixed the outer wall material 20 with the fixing tool 10, the water-tightness between the head 11 of the fixing tool 10 and the cut hole 20a of the outer wall material 20 is ensured, and the water to this cut hole 20a is secured. Deterioration of the outer wall material 20 due to intrusion can be prevented. Moreover, the design which the watertight member 16 is hidden by the head 11 and does not appear in an external appearance can be comprised.

  In the above embodiment, as shown in FIG. 3 (b), a groove portion 17a is formed in the seating surface 17 of the head portion 11, and a part of the watertight member 16 is accommodated in the groove portion 17a. In the configuration shown in FIG. 3B, the outer diameter d1 of the watertight member 16 is made larger than the outer diameter D2 of the head 11 without forming the groove portion 17a. Also, the protrusion of the watertight member 16 from the head 11 may be eliminated by configuring it sufficiently small. In the above embodiment, the watertight member 16 and the head portion 11 (and the shaft portion 15) are configured as separate members. However, the watertight member 16 is provided in a state where it is adhered to the seat surface 17. May be.

In addition, as shown in FIG.
The elasticity of the watertight member 16 is configured to be deformed along the irregularities 22 of the surface 21 of the outer wall material 20 and to be able to be in close contact with the surface 21.

  This closes the gap between the watertight member 16 and the surface 21 and prevents water from entering between the watertight member 16 and the surface 21, so that the inside of the cut hole 20a formed in the outer wall material 20 Water can be surely prevented from entering.

As shown in FIGS. 1 to 5,
The groove portion 17a is formed in an annular shape,
The watertight member 16 is configured in an annular shape,
It is to be configured.

  Thereby, the circumference | surroundings of the cut hole 20a formed in the outer wall material 20 are surrounded by the watertight member 16, and it can prevent reliably that water permeates into the cut hole 20a. In the above-described embodiment, the ring shape is used. However, an elliptical ring shape or a polygonal ring shape such as a square may be used. In addition, even if the ring is not continuous, even if it is composed of discontinuous parts or multiple members, the performance is ensured if the watertight member can be deformed to ensure continuity. It will be possible.

  Moreover, as shown in FIG. 1, the tool insertion hole 12 formed in the said head 11 is made into square shape.

  Thereby, even if the tool insertion hole 12 is configured to be large for transmitting torque of the tool, it is possible to have both design and functionality (torque transmission).

  Further, as shown in FIG. 1, the above-described fixture 10 is used to fix the outer wall material 20 to the building frame (such as the trunk edge 8) and the outer wall material 20 to the building frame (such as the trunk edge 8). According to the building outer wall construction method, since cracks and large internal stresses are prevented from occurring in the outer wall material 20 at the location where the fixture 10 is present, the outer wall material 20 is cracked due to the cracks and internal stress. It is possible to prevent problems such as the occurrence of In particular, when the outer wall material 20 has seismic performance and fireproof performance, it becomes possible to maintain reliable seismic performance and fireproof performance by preventing cracks. As a result, the material cost can be reduced by reducing the wall thickness, Costs can be reduced by eliminating the use of earthquake-resistant materials.

  In addition to the embodiment described above, as in the head portion 11A of the fixture 10A shown in FIG. 6A, the groove portion 17A has a substantially hemispherical groove cross section and an annular portion having a substantially circular cross section.
