Description

  The present invention relates to a nail and a plate material fixing structure for fixing a plate material such as a wall base material to a building frame using the nail.

Conventionally, as a nail which fixes board materials, such as a wall base material of a building, what was indicated in the following patent documents 1 is known, for example. This nail has a sealing agent attached to substantially the entire surface or the tip thereof.
Japanese Patent Laid-Open No. 1-269707

  However, the conventional nail has a sealing agent attached to substantially the entire surface or the tip of the nail. When the sealant adheres to almost the entire surface of the nail, when the plate material such as the wall base material is fixed to the housing of the building using this nail, the adhered sealant adheres to the lower surface of the head of the nail. Excessive accumulation and sandwiched between wall base materials. If the sealing agent is excessively accumulated and pinched, the force with which the head of the nail presses the plate material becomes weak, and there is a possibility that the plate material cannot be securely fixed to the building frame.

  Also, if the sealant is attached only to the tip of the nail, when the nail is driven into the surface of a plate such as a wall substrate, the distance that the sealant travels the body of the nail becomes longer, and the sealant Since the amount of the agent is also small, the sealing agent is peeled off or the amount of the sealing agent accumulated between the bottom surface of the nail head and the plate is too small, and there is a possibility that the intrusion of water from the outside of the plate cannot be prevented.

  The problem to be solved by the present invention is to prevent the intrusion of water from the outside of the plate material and to securely fix the plate material to the building frame.

  In order to solve the above-mentioned problems, the present invention is characterized in that a sealing agent is attached to the surface of the nail from the lower surface of the head to the neck.

  By doing so, the sealing agent adheres to the surface of the nail from the lower surface of the head to the neck, and the sealing agent does not adhere to the trunk and tip of the nail. Therefore, when this nail is driven into the surface of the plate material, the driving resistance is small and it is easy to drive. Further, in the stage of driving the nail and finally driving the neck of the nail, the sealing agent is pushed out from the neck of the nail to the lower surface of the head, and an appropriate amount of sealing agent is sandwiched between the lower surface of the head and the plate material, In addition, the sealing agent is annularly sandwiched around the nail head. In this state, excessive sealing agent does not adhere between the lower surface of the head of the nail and the plate material, so that the plate material is securely fixed to the housing of the building and water is prevented from entering from the outside of the plate material.

  Further, the present invention is a plate material fixing structure for fixing a plate material to a building frame, and the nail with a sealing agent attached to the surface of the nail from the lower surface of the head of the nail to the neck is driven from the surface of the plate material. A plate material is fixed to the housing.

  By doing so, an appropriate amount of sealing agent is sandwiched between the lower surface of the nail head and the plate material, so that the plate material can be securely fixed to the building frame and water can enter from the outside of the plate material. Stop.

  Next, each requirement constituting the present invention will be described in more detail. The nail of the present invention is a commonly used nail (JIS A5508-1992), and has a head portion, a neck portion, a trunk portion, and a tip portion. The shape of the head is flat head flat, with flat head mesh, round head, countersunk head mesh, etc. The shape of the lower surface of the head is a part of an inverted conical surface of 25 degrees or more with respect to the upper end surface of the head (or a surface perpendicularly crossing the torso) or a curved surface in contact with the inverted conical surface and the torso side surface. . The shape of the trunk includes smooth, screw and ring. The material of the nail is a metal such as iron or stainless steel. Selection of the material and size of the nail depends on the purpose of use and the thickness of the plate material. For example, when fixing a plywood with a thickness of 7.5 to 15 mm with an iron round nail, the length depends on the thickness of the plywood. 38-65mm (N38-N65) etc. are used.

  The range in which the sealing agent is attached to the nail is from the lower surface of the head to the neck. Specifically, the length from the head side end of the neck portion to the tip to which the sealing agent is attached is set to be within the range of the radius equivalent dimension to the diameter equivalent dimension of the nail body. By doing so, when the neck portion of the nail is finally driven, the sealing agent is pushed out along the lower surface of the head, and an appropriate amount of the sealing agent is sandwiched between the head of the nail and the plate material.

  If the adhesion length of the sealant on the neck exceeds the size equivalent to the body diameter of the nail, excess nail sealant will be sandwiched between the bottom surface of the nail head and the plate when the nail is driven. Insufficient force to hold the plate material. When the adhesion length of the sealant at the neck is less than the size corresponding to the body radius of the nail, when the nail is driven, the sealant sandwiched between the bottom surface of the nail head and the plate material is too small. There is a risk that water intrusion cannot be prevented.

  The thickness of the sealing agent attached to the nail is set to 0.05 to 1.0 mm. When the film thickness is less than 0.05 mm, the sealing agent is insufficient, and water intrusion from the outside of the plate cannot be prevented. When the film thickness exceeds 1.0 mm, the sealing agent becomes excessive, the force with which the head of the nail presses the plate material is weak, and the plate material cannot be reliably fixed.

  As the sealant, select one that does not adhere to the surface of the nail more than necessary and is pushed out to the nail head side by driving the nail. For example, synthetic resin, synthetic rubber, rubberized asphalt, etc. may be used. . As the synthetic resin, vinyl chloride resin, vinyl acetate resin, urethane resin, or the like is used.

  A board | plate material is formed from a wooden base board with the base material for outer walls. As the base plate, a plywood, a fiber board (medium density fiber board (MDF) or hard fiber board) is used, and a waterproof layer and an inorganic uneven layer are preferably provided on the surface in this order. In the case of an outer wall, the building frame corresponds to a pillar or a stud, but a ventilation receiving material or the like may be interposed.

  When the plate material is fixed to the housing using the nail to which the sealing agent of the present invention is attached, it is driven using a nail group in which a plurality of the nails of the present invention are connected in parallel with each other. If it becomes, construction property will improve.

  According to the present invention, when this nail is driven, an appropriate amount of sealing agent is pushed between the bottom surface of the nail and the plate material, so that water can be prevented from entering the gap between the nail and the plate material. In addition, the plate material can be securely fixed to the building frame. Further, the nail of the present invention is easy to drive because no sealing agent is attached to the trunk and tip.

  Hereinafter, embodiments of a nail according to the present invention and a plate material fixing structure using the nail will be described in detail with reference to the drawings. 1 and 2, the same or equivalent parts are denoted by the same reference numerals.

  FIG. 1 is a cross-sectional view showing an embodiment of a nail according to the present invention. The nail 1 includes a head 3, a neck 5, a body 6, and a tip 8. The size of the nail is, for example, a length L = 50 mm and a thickness D = 2.75 mm. Further, the nail 1 has a shape of the head lower surface 4 formed from a part of an inverted conical surface of 30 degrees with respect to the upper end surface of the head, and a sealing agent on the outer surface from the head lower surface 4 to the neck 5. 10 is uniformly attached. The adhesion length of the sealing agent 10 at the neck is adhered from the head-side end of the neck 5 to a size corresponding to the trunk radius (= D / 2) of the nail. The film thickness of the sealing agent is about 0.1 to 0.5 mm. As the material of the sealing agent, vinyl chloride resin, vinyl acetate resin, urethane resin, or the like can be used.

  FIG. 2 is a cross-sectional view showing a fixing structure of the wall base material in which the wall base material (plate material) 13 is fixed to the building frame 24 using the nail 1 shown in FIG. The nail 1 fixes the wall base material 13 to a building frame 24 such as a pillar or a stud. The wall base material 13 is formed of a wooden base plate 16, a waterproof layer 18 provided on the surface of the base plate, and an inorganic uneven layer 20 provided on the surface of the waterproof layer 18. The base plate is a structural plywood or MDF, and its thickness is, for example, 9 mm. Waterproof paper 22 is provided between the wall base material 13 and the building casing 24. Incidentally, cement-based mortar or the like is applied to the surface of the inorganic uneven layer 20 of the wall base material.

  The waterproof layer 18 is formed by applying a mixture of a latex such as butadiene acrylonitrile rubber, methacryl butyl rubber or styrene butadiene rubber and a synthetic resin emulsion such as vinyl acetate resin, vinyl chloride resin, acrylic resin or chloropyrene resin.

  The inorganic uneven layer 20 is made of a mixture of an aggregate such as calcium carbonate or silica sand, a cement such as Portland cement or white cement, a latex such as styrene butadiene rubber or methacryl butyl rubber, and an emulsion of vinyl acetate resin or acrylic resin. It is applied to the surface of the waterproof layer in a concavo-convex shape. The height (h) of the unevenness of the inorganic uneven layer 20 is about 2.5 mm at the maximum.

  The nail 1 is driven from the surface 14 of the wall base material 13 to the housing 24 side. For example, N50 (JIS A5508-1992) is used as the size of the nail 1. The sealing agent 10 adhering to the head lower surface 4 and the neck portion 5 of the nail is pushed and sandwiched between the head lower surface 4 and the wall base material 13 along the head lower surface 4. The sealing agent 10 is pushed out so as to surround the nail head in an annular shape when viewed from the top of the nail head (when viewed from the top to the bottom of FIG. 2). Since the amount of the sealing agent 10 is an appropriate amount, the entry of water is prevented and the head 3 of the nail reliably presses and fixes the wall base material 13 against the housing 24.

  The inorganic concavo-convex layer 20 is relatively hard and may cause a fine crack when the nail 1 is driven. However, since the sealing agent 10 is sandwiched in this portion, the fine crack is generated. However, the sealing agent 10 adheres to or penetrates and closes the fine cracks, so that water from the outside of the wall base material 13 is prevented from entering the wall base material.

  Although the present invention has been described in detail with reference to the illustrated embodiments, the present invention is not limited to these embodiments. In short, it goes without saying that various modifications can be made and various modifications can be made without departing from the spirit of the present invention.

  The nail and plate material fixing structure of the present invention can be used as a fixing means or a fixing structure for fixing a base material (plate material) provided on an outer wall of an individual house, an apartment house or a building to the building frame.

It is sectional drawing which shows one Embodiment of the nail which concerns on this invention. It is sectional drawing which shows the fixation structure of the wall base material which fixed the wall base material to the building frame using the nail shown in FIG.
