Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement in a basic airtight spacer used in a highly airtight and highly heat-insulated house and the like, sandwiched between a concrete cloth foundation and a wooden base in order to keep the airtight under the floor.
[0002]
[Prior art]
Conventionally, as an underfloor hermetic holding member, an airtight basic packing has been proposed (see, for example, Patent Document 1). The structure of this airtight packing is a flat rectangular rigid synthetic resin block body with a length of about 20 cm, a width of about 10 cm, and a thickness of about 2 cm. Then, these are laid on the top end surface of the fabric foundation in a butted manner, and a base is disposed on the top, thereby making the gap between the fabric foundation and the base an airtight seal.

[0004]
[Problems to be solved by the invention]
However, the hermetic packing is as short as about 20 cm in length, and has a problem that construction efficiency is poor because it is used by connecting it in a butt shape. If the long one is made, this problem can be solved. However, if the long one is made, another problem arises that handling and transportation become difficult.
[0005]
In view of such a point, the present invention provides a basic airtight spacer that is convenient for transportation and has a high work efficiency at the time of construction. Another object of the present invention is to provide a basic hermetic spacer that can be easily and inexpensively manufactured.
[0006]
[Means for Solving the Problems]
The technical means of the basic hermetic spacer of the present invention is a long, hard material spacer body, and an elastic material attached over the entire length in the longitudinal direction so as to protrude from the surface of the spacer body. The main body is subjected to a bending facilitation process so that the main body can be bent in the longitudinal direction .
[0007]
Moreover, it is preferable that the spacer body and the elastic material are continuously and integrally formed by an extrusion molding method. Furthermore, the thickness of the spacer body is increased at the left and right edges, and is decreased from the vicinity of the position where the elastic body is provided to the center , and at least the thick edge is subjected to a bending facilitation process. Good. Moreover, it is preferable to extend the edge part of an elastic material from the edge part of a spacer main body. Furthermore, V-shaped grooves may be formed at appropriate intervals in the longitudinal direction of the spacer body as a process for facilitating bending.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of an airtight spacer of the present invention will be described based on an example of the drawings. FIG. 1 shows the usage state in an exploded state, and the airtight spacer 1 is sandwiched between a concrete cloth foundation 2 and a wooden base 3. 4 is an adjustment plate having a thickness of about 1 to 3 mm. When there is unevenness on the top end surface 5 of the fabric foundation, it is inserted between the spacer 1 and the top end surface of the fabric foundation from both the left and right sides. Try to fill in the gaps that occur between them.
[0009]
As shown in detail in FIG. 2, the airtight spacer 1 includes a spacer body 11 made of hard synthetic resin, and an elastic material 12 made of rubber or soft synthetic resin. The spacer body 11 has a thickness of about 2 to 5 mm, a width of about 80 to 150 mm, and a long body. The spacer body 11 and the elastic material 12 are continuously and integrally manufactured simultaneously by an extrusion molding method. In the illustrated embodiment, the elastic material 12 has a triangular cross section and is attached in parallel to the entire length of both the front and back surfaces of the spacer body 11. However, the number and shape of the elastic material 12 are arbitrary. It is also possible to attach it only to either the front surface or the back surface of the spacer body. Moreover, although the illustrated elastic material 12 is a hollow body, it is also free and is designed as appropriate in order to obtain a desired elastic force. Furthermore, the thickness of the spacer body 11 is thinner at the central portion 13 than at the edge portion 14 from the vicinity of the elastic material attachment position. This is to make the spacer main body 11 bend easily and to keep the elastic restoring force over a long period of time so that the elastic material 12 is not completely crushed when a load is applied.
[0010]
After the extrusion molding, the spacer main body 11 is continuously punched with an anchor bolt hole 15 at the center. Further, slits 16 are formed in the thick edge portion 14 at appropriate intervals. The formation of the slit 16 is to make it easier to curve the thick part of the spacer body 11. In addition to this slit, the bending facilitating process can be freely selected by forming V-shaped grooves from both the front and back surfaces as shown in FIG. 4 or by providing a large number of small holes in a straight line. The formation widths M and N of the holes 15 and the slits 16 are preferably as shown in FIG.
[0011]
Further, on both the front and back surfaces of the spacer body 11, ruled lines 18 are formed at appropriate positions for the convenience of positioning during construction. Further, as shown in FIGS. 3 and 4, an extended portion 19 is formed by projecting the elastic material 12 at the end of the spacer body 11 in the longitudinal direction. This is to prevent a gap from being generated in the abutting portion when the spacers are connected in a butting manner. In addition, it can replace with this extension part and can make it fill a clearance gap with a separate elastic material.
[0012]
FIG. 5 shows another embodiment, in which the elastic material 12 has a rhombus cross section, and the same material is protruded on both the front and back sides, and a spacer body made of a hard material on the middle and left and right sides of the two elastic portions 12 11 is integrally attached. FIG. 6 shows still another embodiment, and the intermediate portion 13 is made of a soft material that is the same material as the elastic material 12.
[0013]
The airtight spacer of the present invention described above is usually provided commercially in a state of being wound in the longitudinal direction or folded. Since the slit 16 and the V-shaped groove 17 are formed at an appropriate interval on the thick edge portion 14 of the spacer body 11, it can be bent and wound. Since the entrainment diameter is usually about 30 to 100 cm, it is convenient for transportation and convenient for handling. An unprocessed hard material exists in the central portion 13 of the spacer body 11, but since it is thin, it does not interfere with the entrainment.
[0014]
At the time of construction, as shown in FIG. 7, the unwinding spacer 1 is laid on the top end surface 5 of the fabric foundation. Since the cloth base 2 is not connected at a straight portion, the work efficiency is good. At the corner position of the fabric foundation 2, it is cut appropriately, and the direction is further changed and laid. At this time, in order to achieve airtightness at the connecting portion, it is preferable to use the extending portion 19 or sandwich a separate elastic material in the gap. At this time, if the extending portion 19 is provided, it is not necessary to use a separate elastic material, which is very convenient. In the case of the outer heat insulation method for a highly airtight and highly insulated house, the spacer of the present invention is arranged on the fabric foundation around the entire building.
[0015]
The base 3 is placed on the airtight spacer 1 laid in this manner and fixed with anchor bolts. At this time, the elastic member 12 is crushed by the load from the base, and the gap between the fabric foundation 2 and the base 3 is completely hermetically shielded by the elastic restoring force. In addition, when there is unevenness on the top end surface of the fabric foundation and a gap is generated, the adjustment plate 4 is inserted from both sides and adjusted. In the present invention, since the spacer body 11 has a certain thickness, the cloth base 2 and the base 3 can be completely blocked, and water moisture can be prevented from reaching the base from the cloth base, thereby preventing the wooden base from decaying. it can.
[0016]
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 thickness and cross-sectional shape of the spacer body 11, the material and shape of the elastic material 12, the number of attachments, the type of bending facilitating process applied to the spacer body 11, etc. are free.
[0017]
【The invention's effect】
The foundation hermetic spacer of the present invention can completely hermetically seal the foundation by laying between the fabric foundation and the base. Furthermore, since the spacer of the present invention is long and is provided in a wound state, the butt connection location can be reduced as compared with the conventional one, the construction work efficiency can be improved, and it is convenient for transportation.
[0018]
According to the second aspect of the present invention, since the continuous molding is performed by the extrusion molding method, the manufacturing cost can be kept low.
[0019]
According to the third aspect, since the thickness of the spacer main body is thick at the left and right edge portions, water and moisture from the fabric foundation can be completely blocked, and the wooden base can be prevented from decaying. Moreover, since it is thin at the position where the elastic material is provided, the elastic material is not completely crushed even when a load is applied, and the elastic restoring force can be maintained for a long time.
[0020]
In the fourth aspect, since the end portion of the elastic material extends, it is convenient for the airtight treatment of the connecting portion.
[0021]
According to the fifth aspect of the present invention, since the V-shaped grooves are formed in the spacer main body at an appropriate interval , the spacer main body is suitable for being bent and wound.
