Description

  The present invention relates to an articulated nail for a continuous nailing machine used when a plate material such as a wall base material is fixed to a building frame.

2. Description of the Related Art Conventionally, as a nail for fixing a plate material such as a wall base material of a building and can be used for a continuous nailing machine, for example, a nail described in Patent Document 1 below is known. This nail has a sealing agent attached to substantially the entire surface or the tip.
Japanese Patent Laid-Open No. 1-269707

  However, the nail has a sealing agent attached to substantially the entire surface or the tip of the nail. A nail having a sealing agent attached to substantially the entire surface is liable to be restricted when connecting a plurality of nails. In addition, when a connecting nail with a plurality of nails with a sealing agent attached to substantially the entire surface is attached to a continuous nailing machine, and the plate material is fixed to the building frame, the sealing agent at the connection location may peel off. is there. When the sealing agent is peeled off, the sealing agent sandwiched between the head of the nail and the wall base material is reduced, and the sealing performance is deteriorated, so that the ingress of water from the outside cannot be prevented.

  Also, if the sealant is attached only to the tip of the nail, when this nail is driven into the wall base material surface, the sealant is peeled off or the seal between the bottom surface of the nail head and the wall base material Since the amount of the agent is small, in this case as well, there is a possibility that water from the outside cannot be prevented.

  The problem to be solved by the present invention is that the plate material can be efficiently fixed to the building frame and that water can be prevented from entering after the plate material is fixed.

  In order to solve the above problems, the present invention includes a plurality of nails and connecting means (or a nail holder) for aligning the nails and connecting the body portions of the nails in parallel to each other, A sealing agent is attached to the surface from the lower surface of the part to the neck part.

  By doing so, the nail is pulled away from the connecting means when the connecting nail is mounted on the continuous nailing machine and the plate member is fixed to the building frame. At this time, since the sealing agent does not adhere to the trunk of the nail, peeling of the sealing agent does not occur. The nail pulled away from the connecting means is driven into the plate material. Further, since the sealing agent is not attached to the trunk and the tip of the nail, the nail can be driven well.

  Furthermore, since the sealing agent is attached to the surface from the bottom surface of the nail to the neck, the sealing agent attached to the bottom surface and neck of the nail is applied to the bottom surface of the head at the final stage of nail driving. And an appropriate amount is sandwiched between the lower surface of the head and the wall base material, and the sealing agent is annularly sandwiched around the head of the nail. In this state, excess sealing agent does not adhere between the bottom surface of the nail head and the plate material, so that the plate material is securely fixed to the building frame and water is prevented from entering from the outside of the plate material to ensure waterproofness. To do.

  Next, each requirement constituting the present invention will be described in more detail. The articulated nail of the present invention is used in a continuous nailing machine, and the plurality of nails are arranged in the direction, that is, parallel to each other, the head sides and the tip sides are aligned and connected by a connecting means.

  The nail itself may be a commonly used nail (JIS A5508-1992), but the shape of the lower surface of the head is an inverted cone of 25 degrees or more with respect to the upper end surface of the head (or a surface perpendicular to the trunk). A part of the surface or a curved surface in contact with the inverted conical surface and the body side surface is used. A nail consists of a head, neck, trunk, and tip, and the shape of the head is flat-head flat, flat-headed, round-headed, counter-headed, etc.

  The shape of the trunk is smooth, screw, ring, etc., and the material of the nail is a metal such as iron or stainless steel. The shape, size and material of the nail are selected according to the purpose of use and the thickness of the plate. For example, when fixing a plywood with a thickness of 7.5 to 15 mm with an iron round nail, the thickness of the plywood Depending on the length, 38 to 65 mm (N38 to N65) or the like is used.

  The sealing agent is selected so that it does not adhere to the surface of the nail more firmly than necessary and is pushed out to the head side by driving the nail. As a material for the sealing agent, for example, synthetic resin, synthetic rubber, rubberized asphalt, or the like may be used. As the synthetic resin, vinyl chloride resin, vinyl acetate resin, urethane resin, or the like is used.

  The range in which the sealing agent is attached to the nail is from the lower surface of the head to the neck. The length of the sealing agent at the neck may be set so that the length from the head side end of the neck to the tip of the sealing agent is not less than the radius equivalent dimension of the nail body and not more than the nail diameter equivalent. By doing so, when the neck of the nail is finally driven into the plate material, 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 at the neck is larger than the size corresponding to the body diameter of the nail, when the nail is driven, excess sealant is sandwiched between the bottom surface of the nail head and the plate material. Insufficient force to hold the plate. If the adhesion length of the sealant on the neck is smaller 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 becomes too small, and water enters. There is a risk that it cannot be prevented. The thickness of the sealing agent attached to the nail is set to 0.05 to 1.0 mm.

  The connecting means is not particularly limited as long as a plurality of nails can be connected. For example, two wires arranged parallel to a predetermined distance, a synthetic resin nail holder, and the like can be used. In the case of two parallel wires, the body of the nail is perpendicular to the wire and fixed by a joining method such as welding, pressure welding or adhesion.

  The plate material fixed with the nail is formed from a wooden base plate with a base material for an outer wall or the like. 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. The continuous nailing machine may be a known one using compressed air.

  According to the present invention, by attaching the articulated nail to the continuous nailing machine and driving the nail, the plate material can be fixed to the building frame efficiently and reliably, and between the head of the nail and the plate material. Prevent water from entering. Further, the connecting nail of the present invention is easy to drive because the sealing agent is not attached to the body and the tip.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a connecting nail according to the present invention will be described in detail with reference to the drawings. 1 to 5, the same or equivalent parts are denoted by the same reference numerals.

(Connecting means or nail holder) 11. Each nail and the wire 11 are joined by an appropriate method such as welding, pressure bonding, or adhesion.

  The nail 2 may be a commonly used nail (JIS A5508-1992), but the shape of the lower surface 4 of the head is 25 degrees or more with respect to the upper end surface of the head (or the surface perpendicular to the trunk) 3a, For example, it is a part of a 30 ° inverted conical surface. Further, the nail 2 includes a head 3, a neck 5, a body 6, and a tip 8. The size of the nail 2 is N50 (JIS A5508-1992), for example, and has a length L = 50 mm and a thickness D = 2.75 mm. In addition, as a continuous nailing machine, the well-known thing which matches with the holder which connects a nail and can drive a nail using compressed air may be used.

  The shape of the head 3 of the nail is a flat-head flat, but other than that, a flat-head mesh, a round head, a dish-head mesh, and the like can be used. The body 6 has a smooth shape, but a screw, a ring or the like can also be used. The material of the nail 2 is a metal such as iron or stainless steel.

  Further, the sealing agent 10 is uniformly attached to the surface of the nail 2 from the head lower surface 4 to the neck 5. The adhesion length of the sealing agent 10 on the neck portion 5 is adhered from the head-side end of the neck portion 5 to a size corresponding to the trunk radius (= D / 2) of the nail, but this adhesion length is limited to this. First, it is intended to adhere the nail to the body radius (= D / 2) equivalent dimension to the trunk diameter D equivalent dimension. The film thickness of the sealing agent is about 0.1 to 0.5 mm. Select a sealant that does not adhere to the surface of the nail more than necessary and is pushed out to the nail head by driving the nail. For example, vinyl chloride resin, vinyl acetate resin, or urethane resin is used. it can.

  FIG. 3 is a cross-sectional view of a state in which the connecting nail 1a shown in FIGS. 1 and 2 is attached to a continuous nailing machine, and the wall base material 16 is fixed to the building casing 24. The nail 2 fixes the wall base material 16 to a building frame 24 such as a pillar or a stud. The wall base material 16 is formed of a wooden base plate 18, a waterproof layer 19 provided on the surface of the base plate 18, and an inorganic uneven layer 20 provided on the surface of the waterproof layer 19. The base plate 18 is a structural plywood or MDF, and its thickness is, for example, 9 mm. Waterproof paper 22 is provided between the wall base material 16 and the housing 24 of the building. 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 19 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 an uneven shape. The height (h) of the unevenness of the inorganic uneven layer 20 is about 2.5 mm at the maximum.

  Next, the operation of the connecting nail will be described with reference to FIG. When the connecting nail 1a shown in FIGS. 1 and 2 is mounted on a continuous nailing machine and the wall base material 16 is fixed to the housing 24 of the building, the nail 2 is driven from the surface 17 of the wall base 16 to the housing 24 side. . The nail 2 is pulled away from the two wires 11 (FIGS. 1 and 2) and driven into the wall base material 16. At this time, since the sealing agent 10 is not attached to the body portion 6 of the nail, peeling of the sealing agent does not occur. Furthermore, since the sealing agent is not attached to the body portion 6 and the tip portion 8 of the nail, the nail 2 is easy to drive.

  In the final stage of driving the nail 2, the sealing agent 10 attached to the head lower surface 4 and the neck portion 5 of the nail is pushed out along the head lower surface 4 and the head lower surface 4 and the wall base material 13. Sandwiched between them. The sealing agent 10 is pushed out so as to surround the nail head in an annular shape when viewed from the front of the head of the nail (when viewed from the top to the bottom in FIG. 3). 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 16 against the housing 24.

  The inorganic concavo-convex layer 20 is relatively hard and may cause a fine crack when the nail 2 is driven. However, since the sealing agent 10 is sandwiched in this portion, even if a fine crack occurs. Since the sealing agent 10 adheres to or penetrates and closes into these fine cracks, water from the outside of the wall base material 16 is prevented from entering the wall base material 16.
