  Furthermore, the present inventor provides a wall heat insulating structure in which a heat insulating unit for a wall in which heat insulating materials are arranged on both sides of a load bearing surface member is fixed to a wall frame structure (for example, a column), and the wall heat insulating unit is attached to a wall. It has also been proposed to employ a so-called double-headed nail having two upper and lower heads as a fastening material for fixing to the frame structure (see Patent Document 4).

Japanese Patent Laying-Open No. 2005-002747 (page 4-5, FIG. 1) Japanese Patent No. 3215826 JP 2004-52362 A JP 2006-307439 A

  However, in the configuration disclosed in Patent Document 4, it is necessary to manually drive the double head nails one by one, and it takes much time and time to construct the required wall insulation structure. There was a problem that the cost of the wall insulation structure would rise. Further, in the driving operation of the double head nails, the driving depth may require skill, and the finish may vary depending on the operator.

  By the way, conventionally, various nailing machines capable of driving a general-purpose nail having a head only at the upper end at a high speed with a constant striking pressure have been proposed. A nailing machine for double-headed nails that can be launched at high speed with a striking pressure has not yet been proposed.

  Then, an object of this invention is to provide the nailing machine which can solve the said problem, and the wall heat insulation structure construction method using this nailing machine.

  The present invention relates to a nail bundle storage portion for storing a nail bundle formed by winding a nail connection product in which a large number of nails are interconnected by a connection band, and a nail bundle storage portion. A nail magazine comprising a nail guide path for guiding a drawn nail connection to a nail hitting position is provided, and the nails guided by the nail guide path and reaching the nail hitting position are sequentially hit against the workpiece. In the nailing machine for driving out the nail, the nail is a double-headed nail having an upper head portion and a lower head portion arranged in two upper and lower stages, and parallel to each other on the road surface of the nail guide path Two guide grooves are disposed along the guide direction of the nail, and both guide grooves are covered with a lid that opens and closes with respect to the nail magazine, and the double-headed nail is positioned at the nail hammering position. Each head of the double-headed nail is disposed in each guide groove covered with a lid. A nailing machine, characterized in that each head is traveling its groove while being guided to the guide groove.

  As described above, when the double-headed nail travels along the nail guide path, the upper and lower heads of the double-headed nails are directed to the nail hitting position while being guided by the groove walls or lids in the guide grooves. Will run. Here, both guide grooves properly limit the axial variation of the double-headed nail, and the lid body restricts the double-headed nail from popping out from the road surface of the nail guideway. As a result, the posture of the nail connection traveling on the nail guide path is stabilized, and the nail connection is smoothly supplied to the nail hitting position. Here, a known nail driver corresponding to a general-purpose nail (single-headed nail) is loaded with a nail connection in which a number of nails are connected to each other by a wire, and the nail connection travels on a nail guide path. In general, by adopting the configuration according to the present invention, it is possible to divert a commercially available nail driver corresponding to the nail connector to the present invention. In addition, the groove width of the guide groove according to the present invention is set as appropriate so that the head can smoothly run in the groove while properly limiting fluctuations in consideration of the thickness of each head of the double-headed nail. It is what is done.

  Further, in the above-described configuration, the auxiliary guide recess in which the inside of the groove communicates with the inner peripheral surface of the lid body in a closed state covering the guide recess and facing at least one of the guide recesses in parallel. When the groove is provided and the double-headed nail is transferred to the nail hammering position, the head that travels in the guide groove may travel in the groove of the auxiliary guide groove.

  In such a configuration, the head travels in the guide passage sandwiched between the guide groove and the auxiliary guide groove, so that the head does not interfere with the travel of the head in the groove. The part is held moderately from both sides to prevent it from jumping out of the groove, and the double-headed nail is prevented from being detached from the nail guide path.

  In addition, a method for constructing the following wall heat insulating structure using the nailing machine for firing the double-headed nail described so far is proposed. That is, according to the present invention, the heat insulating material is adhered to both the inside and outside of the load bearing surface material, the outer heat insulating material is set to have the same vertical and horizontal dimensions as the load bearing surface material, and a notch portion is formed at a predetermined position of the inner heat insulating material. 3. The nail according to claim 1, further comprising: a wall heat insulating unit formed by temporarily fixing the wall heat insulating unit to the wall housing structure by fitting a pillar constituting the wall housing structure into the notch. Double-headed nails with a hammer, against the wall insulation unit so that the tip reaches the pillar, the lower head reaches the outer surface of the load bearing face, and the upper head reaches the outer insulation. A wall heat insulation structure construction method is characterized in that a wall heat insulation unit is fixed to a wall housing structure by driving in from the outside, and a wall heat insulation structure comprising the wall heat insulation unit and the wall housing structure is constructed.

  By adopting such a configuration, it is possible to eliminate the manual work and construct a wall heat insulating structure using a double headed nail.

  Furthermore, in the above method, a configuration is proposed in which the distance between the upper and lower heads of the double-headed nail is substantially equal to the thickness of the outer heat insulating material constituting the wall heat insulating unit.

  In such a configuration, if the upper head is driven at a depth that is visible from the outer surface of the outer heat insulating material, the lower head just reaches the outer surface of the load bearing surface, The nail depth can be minimized. Further, if it is visually confirmed that the upper head portion has reached the outer heat insulating material, it can be easily estimated that at least the lower head portion has reached the outer surface of the load bearing member.

  In addition, in the said structure, the structure which sets the separation distance of the upper side head and lower side head of a double head nail to 35 mm, and makes the thickness of an outer heat insulating material 35 mm-40 mm is suitable.

  By adopting such a configuration, it is possible to construct a wall heat insulating structure that conforms to the current building standard law.

  Moreover, it is good also as a structure using the double head nail which attached | subjected the identification mark which shows that it is a double head nail which also has a lower head on the top surface of an upper head.

  With this configuration, even when the double-headed nail is driven into the outer heat insulating material and the lower head is invisible, the operator can visually recognize the identification mark on the top surface of the upper head exposed outside. Thus, it can be recognized that the nail is a double-headed nail. This makes it possible to identify the type of nail even when other types of nails (for example, general-purpose single-headed nails) are used in combination, and based on the identification mark, the wall insulation unit and the wall frame structure are surely formed by the double-headed nails. Safety confirmation that they are combined is also easy.

  In addition, it is desirable for the shaft diameter of a double head nail to be 2.7 mm-3.3 mm.

  By adopting such a configuration, it is possible to construct a wall heat insulating structure that conforms to the current building standard law.

  The nailing machine of the present invention has two guide grooves parallel to the road surface of the nail guide path, each head of the double head nail is disposed in each guide groove covered with a lid, Since the head is moved in the groove of each guide groove and the double head nail is transferred to the nail hitting position, the nail connection composed of the double head nail is stably and smoothly guided to the nail hitting position. This makes it possible to drive a double-headed nail at a high speed from the nail hitting position at a constant hitting pressure.

  Also, if the cover is provided with an auxiliary guide groove, and the head that travels in the guide groove also moves in the groove of the auxiliary guide groove, the double head nail is prevented from being detached from the nail guide path. There is an effect that can be done.

  Moreover, the wall heat insulation structure construction method according to the present invention includes a wall heat insulation unit, a double head nail, a tip to the pillar, and a lower head to a nailing machine according to claim 1 or 2. Fixing to the wall frame structure by driving from the outside against the heat insulating unit for the wall so that the upper head reaches the outer heat insulating material to the outer surface of the load bearing surface material, and constructs a wall heat insulating structure As a result, it is possible to eliminate the double-headed nail nailing by manual work, and the double-headed nail can be driven out at a high speed with a constant striking pressure, so that the wall insulation structure can be constructed at low cost and in a short time. . In addition, by using a nailing machine, the nailing accuracy is improved and the quality is uniformed.

  If the double head nail head separation distance is set to be approximately equal to the thickness of the outer heat insulating material that constitutes the wall heat insulating unit, the depth at which the upper head reaches the outer surface of the outer heat insulating material. Since the lower head can be made to reach the outer surface of the load-bearing face material, the nail driving depth can be minimized. In addition, there is an effect that it is possible to easily infer that at least the lower head reaches the outer surface of the load bearing member only by visually confirming that the upper head reaches the outer heat insulating material.

  In addition, when the distance between the upper and lower heads of the double-headed nail is 35 mm and the wall thickness of the outer heat insulating material is 35 mm to 40 mm, the wall insulation structure conforming to the current building standard law Can be built.

  In addition, in the case of using a double-headed nail with an identification mark indicating that it is a nail having a lower head on the top surface of the upper head, the top surface of the upper head exposed to the outside is used. It is easy to confirm that the nail is a double-headed nail simply by visually recognizing the attached identification sign, so that the type of nail is easy, and the wall insulation unit and the wall frame structure are surely connected by the double-headed nail. There is an effect that it is easy to confirm safety that they are combined.

  Moreover, when the shaft diameter of the double-headed nail is set to 2.7 mm to 3.3 mm, a wall heat insulating structure that conforms to the current building standard law can be constructed.

Here, the outer heat insulating material 33 is set to have the same vertical and horizontal dimensions as the load bearing surface material 31, as shown in FIG. Further, as shown in FIG. 9, the inner heat insulating material 32 includes notches 37 </ b> A to 37 </ b> C for fitting column bodies (columns 34, intermediate columns 35, horizontal members 36) constituting the wall frame structure. ing. Specifically, the pillars 34 are fitted into the vertically long notches 37A formed at both ends (outer periphery). Further, the stud 35 is fitted into a vertically long notch 37B formed in the center (center). Further, the horizontal member 36 is fitted into horizontally long notches 37C formed at both upper and lower ends (outer periphery). In addition, the position which provides the notch parts 37A-37C in this inner side heat insulating material 32 is set based on CAD data of the blueprint of a building. That is, the notches 37 to 37C are formed at predetermined locations on the inner heat insulating material 32 by a machine tool (not shown) such as a router or a hot-wire cutting machine that is controlled by NC data of the building design CAD data. Cut and make.

  Then, as shown in FIG. 11, in the state in which the column bodies (columns 34, interphase columns 35, horizontal members 36) constituting the wall frame structure are fitted to the notches 37 </ b> A to 37 </ b> C, respectively, A unit 30 is fixed to the wall frame structure by a double-headed nail 2. Specifically, the tip of the double-headed nail 2 reaches the column 34, the lower head 3b reaches the outer surface of the load bearing member 31, and the upper head 3a reaches the outer heat insulating member 33, respectively. The upper head 3 a is at a depth position that is about 10 mm deeper than the outer surface of the heat insulating material 33.

  Further, as shown in FIGS. 10 and 11, an inner wall material is provided on the inner side of the pillars (the pillars 34, the intermediate pillars 35, the horizontal members 36) constituting the wall frame structure fitted to the notches 37 </ b> A to 37 </ b> C. 40 is fixed. A barrel edge 38 is attached to the outside of the wall heat insulation unit 30, and an outer wall material 39 is fixed to the outside of the wall heat insulation unit 30 via the trunk edge 38.

Since the body pillar 34, the interposition pillar 35, and the horizontal member 36 are fitted, when the thickness of the heat insulating materials 32 and 33 is increased in order to improve the heat insulating effect of the building and save energy, the heat insulating material 32, The increase in thickness of 33 can be divided into the inner heat insulating material 32 and the outer heat insulating material 33, and the increase in thickness of the outer heat insulating material 33 can be reduced to ½ or less. Therefore, since it is possible to suppress an increase in the distance between the wall structure of the building and the outer wall member 39 by the amount by which the increase in the thickness of the outer heat insulating material 33 is reduced, the outer wall member 39 is reduced by the wall case structure. In addition to being able to support it sufficiently, it is possible to improve the heat insulation effect of the building and save energy.

Temporary fixing refers to a state in which the wall heat insulating unit 30 itself is held in the wall frame structure by fitting the pillar 34, the intermediate pillar 35, and the horizontal member 36 to the notches 37A, 37B, and 37C, respectively. Thus, it means a state in which the wall heat insulating unit 30 can be easily detached from the wall housing structure as appropriate by the operator.

  Then, the double-headed nail 2 is driven using the nailing machine 1 toward the heat insulating material 33 (work) outside the wall heat insulating unit 30 temporarily fixed to the wall frame structure. Here, the nailing machine 1 is configured so that the tip of the double-headed nail 2 reaches the column 34, the lower head 3b reaches the outer surface of the load bearing member 31, and the upper head 3a reaches the outer heat insulating member 33, respectively.

Can do. Thereby, it is possible to dramatically reduce the cost for assembling the wall heat insulating structure 29.

  Furthermore, in the above construction method, the distance between the upper head 3 a and the lower head 3 b of the double head nail 2 is approximately equal to the thickness of the outer heat insulating material 33 constituting the wall heat insulating unit 30. The structure which does is suitable. By adopting such a configuration, if the upper head 3 a is driven at a depth that reaches the outer surface of the outer heat insulating material 33, the lower head 3 b just reaches the outer surface of the load bearing surface 31. Because.

  In addition, in the said structure, the structure which sets the separation distance of the upper side head 3a of the double head nail 2 and the lower side head 3b to 35 mm, and sets the thickness of the outer heat insulating material 33 to 35 mm-40 mm is suitable. It is. This conforms to the current building standards law.

With this configuration, even when the double-headed nail 2 is driven into the outer heat insulating material 33 and the lower head 3b is invisible, the operator can remove the top surface of the upper head 3a exposed to the outside. It is possible to recognize that the nail is the double-headed nail 2 by visually recognizing the identification mark 6. The identification mark 6 can be distinguished from a nail having another configuration (for example, a general-purpose single-headed nail), and a design or the like may be directly printed on the top surface. It may be formed into a shape.

  In addition, the shaft diameter D of the double headed nail 2 is desirably 2.7 mm to 3.3 mm. By adopting such a configuration, it can be adapted to the current building standard law.
