DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the basic packing of the present invention will be described based on examples of the drawings. The basic packing of the present invention comprises a packing body 1 and an attachment 2 both made of synthetic resin, and both are completely separate as shown in FIGS. 1 and 2 and can be joined and separated. The attachment 2 is connected adjacently to one edge of one side of the packing body 1 or to two edges on both sides. By this connection, the lateral width of the entire packing is increased by the amount of the attachment. In the embodiment, the width of the packing body 1 is 120 mm and the attachment 2 is 15 mm. Therefore, the packing body 1 becomes wider by 15 mm as many as the number of the attached attachments 2 as shown in FIG. In FIG. 5, A is a fabric foundation and B is a base. The packing main body 1 and the attachment 2 are coupled by the coupling portions 3 and 4 provided on the both, respectively, and coupling and separation are extremely simple.
[0009]
Next, the details of the shape of the packing body 1 will be described. In the embodiment, the planar shape is 102 × 120 mm and the thickness is 25 mm. Since the upper surface of the packing body 1 is mounted with a wooden base, it is a substantially flat surface, and an anchor bolt hole 11 is formed at one place. The hole 11 is a long hole and is provided obliquely on the upper surface of the packing. In addition, 12 is a recess for dealing with burrs generated by nailing when nailing the packing to the base, and 13 is a hook for fixing a spacer to be stacked on the upper surface of the packing for adjusting the thickness. Is a hole. In addition, the notch 14 formed on the edge of the packing serves as a hole for an anchor bolt when two packings are used adjacent to each other. The base packing can be attached.
[0010]
As shown in FIG. 3, the surface of the packing body 1 is mostly recessed in the center 16 except for the packing itself and the edge 15 of the anchor bolt hole, mainly for weight reduction. Further, an opening 17 for ventilation is formed at the edge 15, and air can freely pass through the opening 17 in the front, rear, left and right directions. Thereby, since ventilation is possible even with the packing itself, further improvement of underfloor ventilation performance can be achieved. Reference numeral 18 denotes a nail hole, which can prevent cracking of the packing when nailing.
[0011]
The front surface of the attachment 2 is a flat surface as shown in FIG. 1, but the rear surface has a ventilation opening 21 as shown in FIG. Therefore, even when the attachment 2 is coupled to the packing body 1, both of the ventilation openings 17 and 21 communicate with each other to allow ventilation.
[0012]
Next, the joint portions 3 and 4 of both the packing body 1 and the attachment 2 will be described. The coupling portion 4 of the attachment 2 includes an insertion coupling portion 22 that serves as a coupling subject, a central coupling portion 23 that serves as a coupling aid, and a side coupling portion 24. As shown in FIGS. 1 and 4, the insertion coupling portion 22 has a tip 25 that protrudes upward and is bifurcated, and meshing recesses 26 are formed on both sides of the crack. On the other hand, the packing main body 1 is formed with a meshing convex portion 27 corresponding thereto as shown in FIG. Therefore, in the coupled state, the raised portion 25 is hooked on the step portion 28 of the opening 17 and the meshing recesses 26 and 27 are meshed with each other, so that they are held in a fixed state that does not easily come out. Further, the central coupling portion 22 serving as a coupling aid protrudes in a semicircular arc shape and comes into contact with the end portion 29 of the notch 14 during coupling, and the side coupling portion 22 projects in a square shape. Then, it fits into the end 30 of the opening 17. Therefore, the attachment does not wobble in the coupled state, and can be held stably.
[0013]
6 and 7 show a spacer 31 for adjusting the thickness. The spacer 31 is a plate having a substantially triangular shape on a flat surface, and is composed of a set of two sheets having the same shape. It is preferable to prepare a plurality of plate thicknesses having different thicknesses so that they can be selected and used as necessary. The spacer 31 is formed with a notch 32 corresponding to the anchor bolt hole 11 and an elastic hooking claw 33 slightly protruding on the back surface side. The hooking claws 33 are connected to the hooking holes 13 of the packing body and play a role of preventing the pull-out. The hook holes 13 are formed at two locations on the packing body only when the attachment is attached. Therefore, the same spacer can be used when attaching the attachment, which is convenient. Moreover, since the contact piece 34 is attached to the edge of the spacer 31, the stability in an attached state is good. FIG. 7 shows a state in which the spacer 31 is used, and is used so as to overlap the upper surface of the packing.
[0014]
The present invention is not limited to the above-described embodiments, and can be freely modified within the scope of the claims. In particular, the planar shape and thickness of the packing body 1, the shape of the ventilation opening 17, the size and shape of the attachment 2, the number and shape of the coupling portions 3 and 4, the detailed shape of the spacer 31, etc. are free.
[0015]
【The invention's effect】
The basic packing of the present invention can adjust the width of the packing itself according to the width of the base by using an attachment, so there is no need to prepare various packings with different width dimensions as in the past, and it is extremely convenient practically. It is.
[0016]
According to the second aspect of the present invention, since the air flow through the packing itself is possible by the opening, the underfloor ventilation can be further enhanced.
[0017]
According to the third aspect of the present invention, since the attachment also has an opening, the use of the attachment does not impair the air permeability of the packing itself.
[0018]
According to the fourth aspect of the present invention, since the spacer is a planar triangle, the same spacer can be used regardless of whether or not the attachment is used, which is convenient during construction.
