Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an architectural structure in which a wooden base is arranged along a foundation concrete and an outer wall is constructed on the base, and a drainer used therefor.

[0002]

2. Description of the Related Art In Japan, the termite habitat tends to be gradually moving northward, and it is necessary to spread more reliable and safe ant-control measures in a wider area than before.

[0003] As with other building materials, various materials used for termite control must take into consideration health problems and environmental pollution.
A few years ago, in a construction method in which air under the floor was circulated indoors, an accident was reported that caused harm to the health due to the suction of termites installed under the floor.

[0004] Termite control measures are classified into three types: a method using a drug, a method of physically blocking an invasion route, and a method of using both of them.

[0005] Methods using drugs can be further divided into methods using organic drugs and methods using inorganic drugs.

[0006]

In the method using an organic drug, the duration of the effect of the drug is limited. Usually limited to three to five years. In such a method using an organic chemical, there are portions where the construction cannot be performed again.

[0007] The chemicals used are classified into those that impregnate the xylem and those that are sprayed on the surrounding soil.
The chemical to be impregnated into the xylem is mixed with an aromatic volatile organic solvent, and health damage is likely to occur in current airtight homes.

[0008] As the inorganic chemicals, those using boron compounds are known. Since the inorganic chemicals are present in the surrounding environment, they do not significantly damage the environment even when sprayed on soil, depending on the amount used. No contact toxicity and low oral toxicity. The medicinal component is not decomposed, but cannot be used where it is exposed to water because of its water solubility.

The method of physically closing the invasion route has almost no effect on health or the environment, but the biggest disadvantage is that once the block has been breached, it has no effect on termites. .

[0010] For example, in Japanese Patent Application Laid-Open No. 2000-204865, a ventilation layer is formed of a base and an outer wall finishing material (such as siding).
And a termite board that also serves as a drainer has been proposed.
A plurality of ventilation holes are provided in the termite-fixing plate so that outside air is taken into the ventilation layer. The ventilation holes are made smaller in size than the termites, thereby preventing invasion of the termites.

However, such small air holes are likely to deteriorate due to aging and be partially damaged. Once a damage hole larger than the size of a termite is formed in a very small part, there is a disadvantage that the termite invades there.

Further, even if such a broken hole does not occur, the termites that have reached the vent hole die there and accumulate little by little, and in the long term a large amount of dead bodies pass through. Block pores. In addition to termites, much more insects, dust, etc., usually accumulate in the vents of termites than termites. Then, the ventilation characteristics of the building will deteriorate.

An object of the present invention is to provide an architectural structure capable of preventing invasion of termites and easily avoiding adverse effects on human health and the environment, and a drainer used as a component thereof.

[0014]

The following is an example of the solution of the present invention.

(1) In a building structure in which a structural skeleton (steel frame or wooden base) is disposed directly or indirectly on a foundation concrete, and an outer wall is constructed there, in a building structure, the lower end of the outer wall and the foundation concrete are connected. An architectural structure characterized by white termites in between.

(2) The above-mentioned building structure, characterized in that a drain is provided at a lower end portion of the outer wall, and a white dovetail is provided in the drain, preferably in the form of a unit in a ventilation type drain.

(3) The building structure as described above, wherein a gap pawl is mounted on the upper outside of the foundation concrete in order to prevent termites from entering and avoiding termite return.

(4) The building structure as described above, wherein the pawl contains a termite-controlling agent having little harm to the human body, for example, a boron compound or the like.

(5) The building structure as described above, wherein the clogging member is made of clay, synthetic polymer or natural polymer.

(6) The building structure as described above, wherein the foundation concrete is a cloth foundation integrally formed with a solid foundation.

(7) A drainer provided between a foundation concrete of a building structure and a lower end portion of an outer wall, wherein a white dovetail is provided so as to constitute a unit.

(8) A vent is formed in the lower part, and
The above-mentioned drainer, in which a termite bar is provided between the lower vent and the end on the side of the foundation concrete.

[0023]

BEST MODE FOR CARRYING OUT THE INVENTION In a building structure according to the present invention, a wooden base is horizontally arranged directly or indirectly on a foundation concrete, and an outer wall is constructed on the base. Then, a white dovetail is provided between the lower end of the outer wall and the foundation concrete. The termite return means that the termites fall under their own weight.

A construction method that does not use a wooden base is also an object.
Even if steel frame is used for the structural frame,
Buildings that use wood as a finishing material need to be protected from termites.

Preferably, a drain is provided at the lower end of the outer wall, and a white dovetail is provided on the side of the foundation concrete below the drain. As a result, even if the termites rise outside the foundation concrete, they fall down at the termite return and cannot enter. Therefore, it is unlikely that termites will remain as corpses at the termite return.

It is preferable that the termite return is fixed to the drainer as a unit.

In a more preferred embodiment of the present invention, a gap pawl is mounted on the upper outside of the foundation concrete in order to prevent termites from turning back and preventing them from entering through the gap.

[0028] Preferably, the claw contains a termiticide, such as a boron compound or the like. Moreover, it is preferable that the claw-filling material is made of clay, a synthetic polymer, a natural polymer, or the like (plastic).

It is preferable to use a material that adheres itself to a member that comes into contact with the gap pawl or to provide an adhesive between the member and the member.

If a cloth foundation integrally formed with a solid foundation is used to circumvent the invasion of termites from the inside of the foundation concrete, that is, from under the floor, the ant-control effect is further ensured.

The present invention is not limited to a building structure, but is also directed to a drain provided between a foundation concrete and a lower end portion of an outer wall.

The drainer according to the present invention is provided so that the termite turns constitute a unit. In particular, a vent is formed in the lower part of the drain, and a white dovetail is provided between the vent in the lower part and the end on the side of the foundation concrete.

Preferably, ant control of the entire building is reliably performed. As a main component for this purpose, a termite drainer provided with termite turns is used.

Preferably, a drainer, which is a member commonly used in the current wooden construction method, is used, and a physical termite repelling means called a termite is provided there. The clay containing the boron compound is buried in the gaps so as to have an inorganic termite control.

Further, if a foundation work is carried out using a solid foundation into which concrete is poured integrally and an inorganic chemical termite is used together with a part penetrating the foundation part into the ground, the effect becomes more remarkable.

When the physical termite countermeasures and the termite countermeasures using inorganic chemicals are used together, the effects are not only maintained for a long period of time, but also have little effect on the environment and the human body.

The building structure according to the present invention has no large loss compared with the conventional wooden house construction method, so that no special manufacturing cost is required.

When the building structure according to the present invention is applied to a method of mounting packing on a base, the effect is significantly improved. Conventional foundation concrete with ventilation holes creates structural weaknesses. Moreover, the ventilation is uneven. For this reason, packing has been used. Since the packing is only partially laid, there is a gap between the base and the top of the foundation concrete. All these gaps become ventilation holes. A termite bar is provided outside the entrance to prevent the termites from entering the ventilation holes.

Termite turning is physical termite control means,
It is easy to grasp the intrusion route accurately.

The invasion route of termites that inhabit Japan is narrowed down to the following two.

(A) Termites invade from the soil under the floor. Even when concrete is struck inside the cloth foundation, if a gap is formed, termites enter from there.
For example, gaps are likely to be formed around pipes of various facilities standing up through concrete under the floor.

(A) In a place where an environment similar to under the floor occurs due to something being placed on the outer periphery of the cloth base for a long period of time, termites enter from there.

The above-mentioned (A) can be solved by using a conventional construction method or a building material. However, (A) cannot prevent the invasion of termites by the conventional technique.

Therefore, in the present invention, a drainer with a termite turn is used.

The basic structure is to use a conventional vent
It is preferable to provide a termite turn at the ventilation hole.

With a vented drain, air enters from below the drain and either exits above the drain or exits both upward and laterally. This is a function as a vent drain regardless of termites. However, there are times when lateral ventilation can be stopped. That is when, for example, there is no underfloor and the concrete inside is being finished directly. Since this method is not directly related to termite control, it is preferable to provide ventilation holes on both sides as in the case of ordinary drainage so that both members can be used.

As the material of the drainage used in the present invention, those currently used mainly for ventilation drainage can be used. Metal such as aluminum, iron, SUS, or hard plastic.

The effect of termite return, that is, the effect of reliably dropping termites, may depend on the width of the brim-shaped inclined portion and the inverted inclination angle.

It is preferable to set an environment in which termites do not enter from under the internal floor by using an integrated solid foundation or the like.

In order to surely prevent termites from entering the floor, the water supply / drainage inlet pipes are all subjected to entry prevention measures using termite tape. In addition, the outer wall is formed by a ventilation method, and the contact portion between the ventilation sheet, the waterproof sheet, the pillar, and the stud is subjected to a boron-based preservative treatment. In the floorless construction method, airtight packing is used instead of underfloor ventilation packing. However, for the ventilation packing vent, a termite-proof waterproofing sheet or a sheet is used for termite-proof treatment.

When a gap is formed between the drainer and the foundation concrete, termites can pass through the gap, and a plastic filler containing a chemical agent (preferably a boron compound) is preliminarily applied to a place where the gap is likely to be formed.

When packing is provided between the base and the foundation concrete, the packing is laid at a location where the anchor bolt is located. Packing is also placed in places where loads are applied, such as under columns. Packing is also laid at the joints on the base. Packing interval is up to 1,000m
Work within m pitches (approximately half an interval). It is preferable that the packing is laid on all inside and outside of the foundation concrete.

The drainer may be attached to an outer wall, or may be attached to a base or a base plate or the like.

The termite return may be attached to a drainer, or may be attached to something other than the drainer (such as a base or an outer wall).

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
One will be described.

FIG. 1 shows the main parts of a building structure according to one embodiment of the invention, in particular the parts related to draining.

The foundation concrete 10 is a cloth foundation integrally formed on a so-called solid foundation. In this case, the environment is such that termites are difficult to enter from under the inner floor.

The wooden base 11 is used for the base concrete 10
It is fixed horizontally on top. On the surface of the foundation concrete 10, the upper and side foundation finishing mortars 12, 1
3 are formed.

A ventilation packing (not shown) is provided at a predetermined interval between the upper foundation finishing mortar 12 and the base 1.
Are arranged, and as a result, the ventilation slit 14 is formed in a place where there is no packing.

The outer wall 16 is constructed on the base 11 with an exterior material such as siding. On the inside of the outer wall 16,
The moisture permeable waterproof sheet 18 is provided so that the ventilation layer 17 is formed in the vertical direction.

A ventilation type drainer 20 is fixed to the lower end of the outer wall 16.

FIG. 2 shows the drainer 20 in detail.

As shown in FIGS.
0 has an upper part 21 extending upward, a lower part 22 extending horizontally, and an intermediate part 23 existing therebetween. The upper part 21 is fixed to the lower end of the outer wall 16. The lower part 22 is fixed to an upper corner of the foundation concrete 10. The intermediate portion 23 has an outer portion for draining water that has fallen along the outer surface of the outer wall 16 and an inner portion for passing outside air.

A ventilation hole 25 is formed in the lower part 22. In the illustrated example, the vent hole 25 is configured by forming a large number of oval-shaped holes in a line at predetermined intervals. Of course, the invention is not limited to such forms of vents.

The outside air enters the drain 20 through the vent hole 25 as shown by the arrow, and the slit 14 and the vent layer 17
It flows toward.

The lower portion 22 has a projection 26 formed upward at the end on the side of the foundation concrete 10. Lower part 2
A projection 27 is formed downward at the other end of 2.

The lower part 22 is further provided with a white dovetail 30 between the end of the foundation concrete 10 and the ventilation hole 25.
Has been fixed.

The white dovetail 30 protrudes obliquely downward. By setting the width and the inclination angle of the termite return 30 to appropriate values, the penetration of termites is made more effective.

The gap pawl 40 is made of the base concrete 10
To prevent the termites from entering the base 11 from a gap (not shown), avoiding the termite turns 30. In the illustrated example, the clearance pawl 40 has the same thickness as the side base finishing mortar 13, the width (in the height direction in FIG. 1) is about twice the thickness, and the upper base finishing mortar 13 Near the upper edge of the
By doing so, the invasion of termites is more effectively prevented.

The claw filling 40 is a clay containing a boron compound. Prior to construction, the claw pawl 40 is placed in a tube (not shown). At the time of construction, an operator pushes the tube by hand, pushes the claw 40 into a predetermined place, and mounts the claw 40 as shown in FIG.

FIG. 3 shows another embodiment of the present invention.

The embodiment shown in FIG. 3 is similar to the embodiment shown in FIGS.
This is the same as the second embodiment. Members and the like common to both embodiments are given the same reference numerals.

In the embodiment of FIG. 3, the drainer 50 is
It is fixed to the lower end of a projection 28 fixed vertically downward between the ventilation hole 25 of the lower part 22 and the end on the side of the foundation concrete 10.

FIG. 4 shows still another embodiment of the present invention.

The embodiment of FIG. 4 is a modification of the embodiment of FIGS. That is, the upper end of the gap pawl 40 extends to the same plane level as the upper surface of the upper finishing mortar 12. Then, the position of the upward protrusion 26 is separated from the extension of the side surface of the foundation concrete 10 by the thickness of the gap pawl 40. In this case, even if the thickness and the like of the upper and side basic finishing mortars 12 and 13 change after construction, it is easy to secure a favorable action of the claw pawl 40.

The lower end of the downward projection 28 extends slightly beyond the upper end of the lateral base mortar 13 and is in contact therewith. As a result, the gap pawl 40 is covered by the projection 28. As a result, water may be applied to the crevice 40, or at any time, a hard object may be caught in the crevice 4
Deformation or damage caused by contact with zero is avoided.

FIG. 5 shows still another embodiment of the present invention.

In the embodiment shown in FIG. 5, the gap pawl 4 is located at a position lower than the level of the upper end face of the foundation concrete 10.
The upper end of 0 is set. As a result, the occurrence of dew condensation is limited to the inside of the foundation concrete, and the influence on wood can be minimized. Insulating both the outside and the inside of the foundation concrete can minimize condensation.

In FIG. 5, a heat insulating material 52 is provided only on the outside of the foundation concrete 10, and a foundation finish 53 is formed on the outside thereof. A heat insulating material 51 is also provided inside the ventilation layer 17. Foundation 11 and foundation concrete 10
There is no ventilation layer between the two. The upward projection 26 of the drain 20 extends relatively long, and the opposite downward projection is omitted. The upper end of the basic finish 53 is disposed adjacent to the termite bar 30.

The present invention is not limited to the above-described embodiment.
For example, the termite return is not limited to the shape of a single plate as shown in the figure, but may adopt various shapes. For example, the white dovetail may be a long object having an inverted Y-shaped cross section. When the ventilation hole has a hole shape as shown in the figure, the white dovetail may be formed into a trumpet shape so as to surround the hole, and a trumpet-shaped white dovetail may be provided for each hole. .
