Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a base protection plate.

[0002]

[Technical background of the device]

At present, the concrete foundation standard for wooden houses established by the Housing Finance Corporation is to install a ventilation hole of 300 cm ² for 5 m in the upper part as much as possible, and a ventilation hole interval of 4 m or less. In the structure of a wooden house, the corner timbers that serve as the base are surrounded on the concrete foundation, and the concrete foundation and the corner timbers that serve as the foundation are clamped and fixed with the anchor bolts planted in the concrete foundation, and the pillars are placed on top of this. It is well known that after the timber was assembled, various constructions were carried out to build houses.

[0003]

[Prior art and its problems]

 However, houses constructed by the conventional method, especially wooden houses, surround the corner timbers that are the foundation directly on the concrete foundation, so if the concrete foundation becomes wet with rain, underground moisture, or other moisture, the moisture will be generated. It was a cause of seeping into the base timber and corroding the base timber, which was a cause of shortening the useful life of the wooden house. In addition, it is the actual situation that the ventilation volume determined by the ventilation holes, which is set as a standard, cannot be expected so much due to the structure of the above-mentioned concrete foundation and foundation.

Further, as shown in FIG. 8, the airtight performance of the house has been increasing along with the call for energy saving. However, the dew condensation inside the wall caused by the temperature difference between the inside and the outside of the house and the typhoon and It is self-evident that all rainwater entering through the joints and cracks on the outer wall due to strong wind will drip and stay between the concrete foundation and the foundation unless it dries and evaporates.

In addition, with respect to human vibrations caused by vibrations of trains, automobiles, factories, etc., and roaring noises generated from machines, etc., since a square bar to be a base is directly surrounded by a concrete foundation, The vibration of the concrete foundation due to the vibration is directly transmitted to the corner timber, which is the base, and causes anxiety and discomfort to the occupants.

As a means for solving the above problems, a long protective plate made of an elastic material having the same effect such as rubber, synthetic rubber or the like and having an expanded structure in the longitudinal direction is used as a concrete foundation. A base protection plate has been proposed that is provided between the base and the timber. (For example, see Japanese Utility Model Publication No. 1-16811)

According to such a protection means, the effect of protecting the corner timber, which is the base laid on the concrete foundation, from moisture is recognized, but since the protective plate and the timber are in a close contact structure, the concrete foundation It is impossible to prevent the infiltration of moisture and dew condensation on the inner surface of the wall, and the infiltration of rainwater from joints and cracks on the outer wall, and as a result, the foundation will be adversely affected. In addition, since the protective plate itself has a thin structure, even if it can be expected to have some degree of absorption effect against the above-mentioned vibration, the absorption degree is not only slight, but also white ant, black ant, red ant. There remains the problem of being completely vulnerable to pests such as dumplings and ants because they are ants, dead, and easy.

[0008] Furthermore, a mat which is the same as the base or slightly wider than the base is provided with protrusions on the front and back surfaces (for example, Japanese Patent Laid-Open No. 60-13150), and a large number on the front surface of the sheet main material. A moisture-proof sheet in which the above-mentioned protrusions are arranged has been proposed. (For example, Japanese Utility Model Laid-Open No. 6-110706)

According to this type, a ventilation gap is formed between the foundation and the base to safely protect against moisture, and in addition, an absorption effect of human vibration can be expected, but with this configuration The problem remains that the foundation cannot be protected from pests.

The object of the present invention is to safely protect the base timber against moisture from the concrete foundation, and in addition, to keep pests such as termites eradicated and exterminated rationally and for a long time. In addition, it is intended to provide a base protection plate that is highly effective in absorbing human vibration.

The structure of the present invention which solves the problems of the prior art is less in the base protection plate in which a large number of protrusions are integrally formed on the entire upper surface of the protection plate made of rubber, synthetic rubber or other elastic material having the same effect. In addition, chemicals such as termite insecticides and pesticides were attached to the entire upper surface of the protective plate and the entire surface of a large number of protrusions formed integrally with the protective plate, and at least the upper surface of the protective plate. The entire surface and the entire surface of a large number of protrusions integrally formed on the protective plate have a rough surface structure including fine irregularities.

[0012]

[Action]

 The ventilation gap formed between the timber and the foundation greatly increases the ventilation volume, effectively blocking the moisture and humidity from the concrete foundation to the timber and preventing the corrosion of the timber as the base. The presence of the protrusions exerts the effect of absorbing human vibration, improves the resident's comfortability, and facilitates the killing and extermination of harmful insects such as termites by drugs and the supplementation of drugs.

Reference numeral 1 in FIG. 1 is a long protective plate made of rubber, synthetic rubber, synthetic resin or other elastic material having the same effect, and a projection 2 having a tapered structure is formed on the entire surface of the protective plate 1. Is formed integrally. Although the projection 2 is formed in a truncated cone shape as shown in the figure, similar effects can be obtained with a truncated pyramid shape, a prismatic shape, or a cylindrical structure, so that it is not specified as the illustrated embodiment. Absent. By the way, the upper side diameter of the protrusion 2 is about 9 mm, the base diameter is about 11 mm, and the height is 6 mm (strain due to load is 1 mm). Further, in FIG. 1, the projections 2 are formed in a grid pattern, but they may be arranged in a zigzag pattern.

Although the length and shape of the protective plate 1 are arbitrary, an engaging projection 3 having a protrusion 2 is provided at the central portion of one end of the protective plate 1, and the central portion of the other end of the protective plate 1 is also provided. An engaging recess 4 into which the engaging projection 3 is properly fitted is formed in the plate so that no gap is formed between the protective plates 1 that are continuously provided. Further, it is preferable that the width of the protective plate 1 is at least approximately the same as the width of the concrete foundation 5 and the width of the square bar 6 serving as the base. Further, it goes without saying that a hole through which the anchor bolt 7 planted in the concrete foundation 5 can be inserted can be formed at an arbitrary position of the protective plate 1.

When the protective plate 1 of the present invention is used for building a house, first, after forming a hole in the protective plate 1 at a portion to which the anchor bolt 7 planted in the concrete foundation 5 fits, The protection plate 1 is laid on the concrete foundation 5 while inserting the anchor bolt 7 into the hole. The protective plates 1 that are continuously provided are laid in a seamless manner on the engaging projections 3 and the engaging recesses 4 with fitting and engaging means. Thereafter, according to the conventional construction method, the square bar 6 serving as a base is mounted and fixed on the protective plate 1 as shown in the figure, and the height of the protrusion 2 is provided between the square bar 6 and the protective plate 1. The ventilation gap 8 is formed, and the timber 6 thus constructed is used as a base to construct a house.

FIG. 4 shows another embodiment of the protection plate 1. The protective plate 1a is formed by integrally forming a hanging side 9 on the longitudinal side edge of the protective plate 1 so that the end face shape is a downward U shape. The inner surface of the hanging side 9 of the protective plate 1a and the concrete foundation A slight gap is formed between the concrete base 5 and the side surface of the concrete 5 to prevent the moisture of the concrete foundation 5 from propagating and to prevent harmful insects such as termites from reaching the timber 6. In addition, by adding ore grains or powders that are harmful to harmful insects such as termites or the like to the material forming the protective plates 1 and 1a, damage by the harmful insects can be further prevented.

FIG. 5 shows a plan view of the engaging projections 3 and the engaging recesses 4 shown in FIG. 1 in a wedge shape, and when the base material of the square bar 6 is laid on the concrete foundation 5, the protective plate 1 is laid. The protection plate 1 is designed so as to prevent the protection plates 1 from moving in the pulling direction or separating from each other. In the present invention, as shown in FIGS. 6 and 7, at least the entire upper surface of the protective plate 1 and the entire surface of the protrusion 2 are formed with a rough surface structure 10 having fine unevenness and the like. As shown in FIG. 7, a drug layer 11 for controlling harmful insects such as termites, which is commercially available, is attached to the entire surface of the rough structure 10, and the rough structure 10 is interveningly filled with the drug layer 11. As a means for attaching the medicine, the entire protective plate 1 is dipped in the chemical solution and taken out and dried, or applied, or sprayed and applied. In addition, before attaching the drug, a drug viscous material or an adhesive that enhances the drug adhesion rate may be applied to the entire upper surface of the protective plate and the entire surface of the projection group to prevent peeling.

[0019]

[Effect of device]

 As described above, according to the configuration of the present invention, the following effects can be obtained. (A) Since a protective plate made of an elastic material such as rubber or synthetic rubber is interposed between the concrete foundation and the base square member, the moisture contained in the concrete foundation is protected from rainfall and other causes. It is possible to prevent the square wood from being corroded by moisture due to being blocked by the plate, and it can be expected to have the effect of absorbing human vibration, etc. Furthermore, by forming a number of protrusions on the entire surface of the protective plate as a base, A ventilation gap corresponding to the height of the protrusion is formed between the rectangular timber and the protective plate, and this ventilation gap can greatly increase the ventilation volume from the ventilation hole and further reduce the influence of moisture. At the same time, it is possible to remove moisture due to the ventilation effect, which can improve the wide-ranging effect of protecting the timber. (B) Condensed water in the wall of the building and rainwater that invades even if it invades the concrete foundation, the water will not directly contact the base and corrode it due to the presence of the projections. The connection with the foundation can be maintained in an ideal state for a long period of time, and the economic effect is great such that the life of the wooden house can be greatly extended, and at least the entire upper surface of the protective plate is Moreover, since a pest control agent layer such as a termite is provided on the entire surface of the group of protrusions, the base is not eroded by these pests, and in addition to the above effects, the life of the house can be further extended. In addition, the drug layer is secured by the rough surface structure formed on the entire surface of the protective plate, does not peel off during handling, and the rough surface structure can double the amount of drug to be added, thus prolonging the drug effect. . (C) In particular, according to the present invention, the production of the termite exterminating drug is restricted due to the influence on the natural environment, and the duration of maintaining the medicinal effect is 5 to 10 years. It is possible to easily supplement drugs and renew drug efficacy.
