Description

  [Technical Field] The present invention relates to a base plate with packing used as a base plate of a wooden building.

  The foundations of wooden buildings such as houses are a number of issues such as moisture from the ground, humidity and ventilation under the floor, heat insulation from the ground and outside air, measures against insects such as termites, and earthquake countermeasures related to fixing the base and houses. have. Many proposals have been made regarding the structure and construction methods related to these issues.

  As one of the proposals, a vibration-damping sheet that has seismic isolation and has protrusions on both the upper and lower sides is laid along anchor bolts that are continuous from the foundation, and the foundation that has anchor bolt insertion holes on it is anchored. There is a damping sheet that is inserted between the foundation and the base to dampen the vibration by inserting and laying the bolt, attaching a washer to the anchor bolt, tightening with a nut, fixing by crimping, and using it (for example, Patent Document 1).

  As another proposal, a wooden base is fixed on a concrete foundation of a wooden house and a wooden house via a hard vibration-absorbing rubber material arranged at a predetermined interval, and between adjacent vibration-absorbing rubber materials. This is a fixed structure for a wooden house and a wooden housing base with a ventilation opening (see, for example, Patent Document 2).

  Other proposals include a foundation body on the ground, a foundation on the foundation body, a stone layer on the ground in the floor formation area based on the foundation body, and each installation of this stone layer. At a point, a plurality of basic bundles consisting of a support base having a fitted part, a screw-like fitting part screwed to the support base so as to be height-adjustable, and a receiving member having a single surface receiving plate are simply provided. A step of installing the beam member horizontally on the foundation bundle after adjusting the height of the screw-like fitting portion corresponding to the height of the beam member, and then from above the stone layer in the floor forming region There is a floor foundation construction method that includes a step of placing a ground concrete for heat propagation, and then a step of providing a floor member above the beam member. The floor foundation construction method includes a square member (base material) and a steel material. Are used which are integrally fixed to each other (for example, Patent Document 3, see FIG. 8).

  Another proposal is an elastic packing for building structures in which a plurality of ventilation grooves are formed, and a double-sided adhesive tape is provided on one side of the packing (for example, patents) Reference 4).

  There is another wooden wooden building base that is fixed on the foundation and is carbonized on the lower surface of the foundation that comes into contact with the foundation. (For example, refer to Patent Document 5).

Utility Model Registration No. 3093557 Japanese Patent No. 3759241 Japanese Patent No. 3984182 Utility Model Registration No. 3017536 JP 2003-049490 A

  Since the vibration damping sheet disclosed in Patent Document 1 is not fixed to the base, the vibration damping sheet is arranged at a predetermined position of the foundation at the time of enforcement, and the vibration damping sheet does not move when the base is installed. There is a problem that must be made.

  The foundation fixing structure proposed by Patent Document 2 also has an elastic body packing that is not fixed to the foundation. When the foundation is installed, the damping sheet is placed at a predetermined position at the time of enforcement. There is a problem that the vibration sheet must be prevented from moving.

  Since the square members (base materials) proposed by the cited reference 3 and the like are integrally fixed to each other, it is impossible to cut them with a saw or a rotary blade cutter used in general wooden construction, Its use is very limited.

  In addition to being troublesome to install the packing, the elastic packing for building structures proposed by the cited reference 4 etc. is not fixed to the square material (wooden base) and is placed on the concrete foundation at the time of enforcement. Thus, there is a problem that the installed packing must be prevented from shifting after installation. If double-sided tape is applied to the surface of the packing that comes into contact with the concrete foundation, the packing can be fixed to the concrete foundation, but the packing and the square (wooden foundation) cannot be fixed.

  The foundation for a wooden building proposed by the cited document 5 or the like has a carbonized surface layer on the surface of the foundation in contact with a concrete foundation. Due to the moisture-proof action of the carbonized surface layer, the entire length of the foundation has a moisture-proof action, and the foundation having the carbonized surface layer can be cut with a saw or a rotary blade cutter used in general wooden construction. Therefore, the wooden building foundation proposed by cited reference 5 etc. is easy to use as a base material, but has a poor moisture-proof function, and the carbonized surface layer is very fragile, and its usable area and land are limited. There is a problem of being.

(First embodiment)
As shown in FIG. 1, the base plate 10 with packing according to the first embodiment is formed by fixing a packing member 14 to a base base member 12 with an adhesive element 16. The base plate 10 with packing is arranged on the concrete foundation 18 and fixed to the concrete foundation 18 by anchor bolts 20 planted on the concrete foundation 18.

(Basewood member)
The base wood member 12 has a rectangular cross section, and is a solid material obtained by cutting natural wood, a laminated material such as a synthetic material, or the like. The length dimension is often selected from 180 cm, an integer multiple of 180 cm, an integer multiple of 200 cm, or an integer multiple of 200 cm in consideration of usage, manufacturing equipment, storage location, transport equipment, weight, and the like. The thickness dimension is often 120 mm × 240 mm, or 4 dimensions (120 mm) square.

(Packing material)
As shown in FIG. 2, the packing member 14 is formed by cutting a continuously molded member into an appropriate length by an extrusion molding apparatus described later. The packing member 14 has an anchor bolt hole 30 as desired.

  As shown in FIG. 2, the packing member 14 has a large central through hole A having a rectangular cross section along the longitudinal direction inside the long plate-like body. Along each side of the central through hole A, there are two or more small side edge through holes B having a rectangular cross section with a width narrower than the width of the central through hole A symmetrically on the left and right. The large central through hole A and the small side edge through hole B are effective for reducing the molding material and reducing the heat transfer coefficient of the packing member 14.

  Two linear protrusions 30 are formed on the lower surface of the packing member 14, that is, the surface in contact with the concrete foundation 18. The cross-section of the linear protrusion 30 is, for example, an isosceles triangle. When the packing member 14 is disposed on the concrete foundation 18, the linear protrusions 30 are deformed by the irregularities on the upper surface of the concrete foundation 18, thereby improving the airtight barrier properties of the inner and outer regions formed on both sides of the concrete foundation 18. The dimensions of the linear protrusion 30 are, for example, a height of 3 mm and a base width of 5 mm.

  The dimensions of the packing member 14 are exemplary, but the thickness (height) is 10 to 30 mm, preferably 20 mm. The dimensions of the through holes A and B are determined so that the thicknesses of both side walls and the upper and lower surfaces thereof are 1.5 to 5 mm, preferably 2 to 4 mm, more preferably 3 mm. Is done.

Since the material of the packing member 14 is preferably formed using a polyolefin-based resin composition, a polypropylene-based resin composition is preferable.
This polypropylene resin composition contains a polypropylene resin, an inorganic filler, and a carbon black colorant. When sink marks are conspicuous in the molded product, it is preferable to add a chemical foaming agent.

Examples of the polypropylene resin include a propylene homopolymer, a propylene-ethylene block copolymer, a random copolymer, and a propylene-ethylene-diene compound copolymer.
Of the polypropylene resins, crystalline polypropylene resins are often used. Examples of the crystalline polypropylene resins include isotactic propylene homopolymers having crystallinity, ethylene having a low ethylene unit content, and the like. Propylene random copolymer, propylene block copolymer composed of a homo part composed of a propylene homopolymer and a copolymer part composed of an ethylene-propylene random copolymer having a relatively large content of ethylene units, and Examples thereof include crystalline propylene-ethylene-α-olefin copolymers in which each homo part or copolymer part in the propylene block copolymer is further copolymerized with an α-olefin such as butene-1.

Examples of the inorganic filler include calcium carbonate, magnesium carbonate, aluminum hydroxide, magnesium hydroxide, kaolin, silica, pearlite, calcium sulfate, barium sulfate, calcined alumina, calcium silicate, talc, mica, and the like. You may use individually and may be used in combination of 2 or more type.
Among these inorganic fillers, calcium carbonate, talc, aluminum hydroxide, and magnesium hydroxide are preferable from the viewpoint of machinability and economy. Particularly, from the viewpoint of improving compressive strength and economy, fillers containing calcium carbonate are preferable. Is preferred. The calcium carbonate is not particularly limited, and any of precipitated calcium carbonate, heavy calcium carbonate, light calcium carbonate and the like can be used. The average particle size of the calcium carbonate is usually in the range of 0.05 to 200 μm, preferably 45 to 75 μm.

The content ratio of the polypropylene resin and the inorganic filler in the polypropylene resin composition is generally about 40:60 to 90:10, preferably 70:30, in mass ratio.
Examples of the blowing agent include organic blowing agents such as azodicarbonamide (ADCA), azobisisobutyronitrile (AIBN), dinitropentamethylenetetramine (DPT), p-toluenesulfonyl hydrazide (TSH); Examples include inorganic foaming agents such as sodium, ammonium carbonate, and ammonium bicarbonate.
These may be used individually by 1 type, and may be used in combination of 2 or more, and the usage-amount is a value which the foaming magnification of the basic packing 100 obtained becomes the range shown above. It is. The polypropylene resin composition can contain a carbon black colorant, and the content thereof is about 0.5 to 3.0 parts by mass, preferably 1.0 with respect to 100 parts by mass of the polypropylene resin. It is -2.0 mass parts, More preferably, it is 1.5 mass parts.

  In the case where there is a risk that sink marks after molding on the both side walls and upper and lower surfaces of the through-holes A and B greatly deviate from the standard, the expansion ratio is about 1.01 to 1.5 from the viewpoint of preventing sink marks and improving the appearance. It is conceivable to solve this problem by using a low foam of 1.04.

  The adhesive element 16 is an adhesive or a double-sided adhesive tape. Examples of the adhesive include “Cemedine SX-PPK1000” (registered trademark) manufactured by Cemedine Co., Ltd. Examples of the double-sided pressure-sensitive adhesive tape include “Strong pressure-sensitive adhesive tape No. 9712” manufactured by 3M.

(Extruding equipment)
The extrusion molding apparatus 100 is, for example, a 90 mm single screw extruder. As shown in FIGS. 7 and 8, the extrusion molding apparatus 100 includes a power supply box 113, an operation panel 114, a raw material charging hopper 115 for charging a molding material such as a polypropylene resin composition, and a first extruder (90φ, 32D). 116, an extrusion die 117 and a sizing die 118 for shaping the same shape as a cross-sectional shape obtained by cutting a long plate-shaped body of packing perpendicularly to the longitudinal direction, a sizing die operation panel 119, a cooling bath 120, a pulling device 121, an anchor bolt drilling device 122, a cutting device 123, and a stacker (stacking device) 124.

  In the extrusion molding apparatus 100, the molding material is filled into the first extruder 116 via the raw material charging hopper 115. In the first extruder 116, the molding material is melt-kneaded to extrude the molten resin, and the elastic material is filled into the second extruder 125 (30 mm uniaxial) from the raw material charging hopper 126, and further melt-kneaded, The molding material is extruded into the cross-sectional shape of the extrusion die 117.

  The molded body extruded from the extrusion molding die 117 is taken up at a speed of 2 m / min by the take-up device 121, cooled in the cooling tank 120 through the sizing die 118, and then optionally drilled for anchor bolts. By the device 122, an oblong anchor bolt hole 30 (long diameter 160 mm, width 30 mm, arc portion φ30 mm, distance between holes 40 mm) penetrating the upper and lower surfaces and extending in the longitudinal direction is provided. Next, after being cut into a predetermined length by the cutting device 123, they are collected by the stacker 124.

(how to use)
The packing member 14 manufactured in this way is fixed to the base tree member 12 by the adhesive element 16 in a factory or the like, and then cut to a predetermined length to form a product “base plate with packing”. The base 10 with packing is sold as a base material for a wooden building, for example, to a lumber trader or a so-called precut trader.
A pre-cutting company or the like cuts to a predetermined length using a conventional processing machine for base wood, drills an anchor bolt hole 50 with a countersink hole 55 if necessary, and further performs end machining if necessary. For anchor bolt hole drilling, the anchor bolt 60 hole 30 formed in the packing member 14 in advance can be used. At the time of these processes, the base 10 with packing is a unitary object, which is not different from conventional wood processing. A nut 62 is screwed into the anchor bolt 30 with a washer 60 interposed therebetween, and the base plate 10 with packing is fixed to the concrete foundation 18.

(Second Embodiment)
The packing base 200 with packing according to the second embodiment is shown in FIGS. 4 to 6, but substantially the same components as those of the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. The description of the embodiment is cited.

(Packing material)
As shown in FIG. 5, the packing member 214 is continuously formed by the extrusion molding apparatus 100, cut into an appropriate length, and a plurality of ventilation grooves 200 orthogonal to the length direction are cut. Formed. The packing member 214 has an anchor bolt hole 230 as desired.

As shown in FIG. 5, the packing member 214 has a large central through hole A having a rectangular cross section along the longitudinal direction inside the long plate-like body. Along each side of the central through hole A, there are two or more small side edge through holes B having a rectangular cross section with a width narrower than the width of the central through hole A symmetrically on the left and right.
The packing member 214 further has a plurality of ventilation grooves 200 orthogonal to the length direction on the upper surface.

  The dimensions of the packing member 214 are exemplary, but the thickness (height) is 10 to 35 mm, preferably 20 mm. The dimensions of the through holes A and B are determined so that the thicknesses of both side walls and the upper and lower surfaces thereof are 1.5 to 5 mm, preferably 2 to 4 mm, more preferably 3 mm. Is done.

  For example, the ventilation groove 200 has a width of 100 mm, a depth of 5 mm, and a corner formed by the bottom and the side wall of the ventilation groove 200 has a cylindrical shape with a radius of 6 mm. The space | interval (pitch) of the ventilation groove | channel 200 is 50 mm at both ends, and the middle of 90 cm and 100 cm is equally divided into five.

(Advantages of the device)
In the implementation of wooden buildings, placing a packing member between the concrete foundation and the foundation tree will ensure that the insulation heat insulation effect from the geothermal and cooling grounds and the airtightness inside and outside the concrete foundation and foundation tree will be maintained. It is known that there is a great effect in preventing the damage of white ants and the like by preventing the effect and ground moisture from being transmitted to the base tree, and the packing member is arranged at a predetermined position.

  However, the conventional packing member is an independent building material and exists alone in the market. The packing member is placed at a predetermined position on the concrete foundation by a construction worker during construction, and a base tree is placed thereon. If the packing is not accurately positioned with respect to the concrete foundation, the desired function as a packing cannot be achieved. There is a risk that it will not be able to perform its intended function. And the length of the conventional packing is 100 mm-1000 mm, and it did not arrange | position continuously on a concrete foundation. Therefore, the above-described fear is further increased by the existence of a space between the packings. In particular, the hindrance to the airtightness between the areas on both sides of the concrete foundation and the basement was significant. There is also a risk of packing slippage due to an earthquake.

On the other hand, according to the base plate with packing of the present invention, the packing member and base base member can be cut and anchor bolt hole drilling can be performed in one process, so that the packing arrangement work is not necessary. Accurate positioning of the packing and base wood can be ensured easily and with high accuracy.
Furthermore, a high degree of airtightness between the areas on both sides of the concrete foundation and the basement can be ensured by the seamless packing.
Furthermore, the fact that the packing member and the base wood member are integrated means that even if the building is displaced with respect to the concrete foundation due to an earthquake or the like, the position of the packing with respect to the base wood member does not change, and the desired function of the packing is achieved. Maintained.

  Moreover, in the conventional building which provides a ventilation hole with a grid in a concrete foundation, in order to supplement the intensity | strength of the part which provided the ventilation hole with a grating | lattice, it was necessary to change the reinforcing bar of the part into a steel frame structure. However, in the second embodiment, since the latticed ventilation grooves are provided, ventilation can be ensured by a conventional reinforced concrete foundation without providing a latticed ventilation port.
