[Problems to be solved by the device]

 In the foundation of the building as described above, in order to secure the circulation of air under the floor in summer and to create a comfortable living environment, the ventilation port 200 shown in Fig. 4 should be provided in the non-embedded portion of the foundation. Is preferred.

However, such a ventilation port 200 effectively functions in the summer in a cold region, but in the autumn and winter when the temperature is low, the heat retaining property is deteriorated, which is not preferable. Therefore, in winter, it is desirable to maintain the airtightness of the lower part of the floor and to exert an effective heat insulation effect.

Therefore, in the above-described conventional structure of the foundation part, when the ventilation port 200 is provided, there is a problem that the heat insulation effect of the foundation part is deteriorated in a low temperature period. If 200 is not formed at all, there is a problem that it is not possible to ensure air circulation under the floor in summer when the temperature is high.

The present invention has been made to solve the above-mentioned problems, and its purpose is to ensure good circulation of air under the floor in the summer and to provide a basic function in the autumn and winter. It is to provide a foundation beam structure that can ensure good heat insulation.

[0010]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, according to the foundation beam structure of the present invention, a part of the structure is embedded in the ground where the structure is built, and a plurality of the precast structures that form the foundation of the structure are built. In a foundation beam structure having a concrete foundation beam main body, a heat insulating material provided on the entire inner side surface of the foundation beam main body in an installed state, an outside air and an underfloor space partitioned by the installed foundation beam main body A ventilation opening provided in a non-embedded portion of the foundation beam main body, and a lid detachably attached to the ventilation opening of the foundation beam main body from outside the building.

[0011]

[Action]

 The present invention was made on the basis of the basic construction of a building using a foundation beam previously proposed by the applicant in order to improve the efficiency of the construction work of the building foundation at the construction site. Is constructed by connecting a plurality of foundation beam bodies.

Therefore, basically, simplification of the construction of the foundation of the building on the construction site has also been achieved.

Further, a heat insulating material is provided on the inner side surface of the foundation beam main body, that is, on the side surface under the floor, so that the heat insulating effect is improved in a low temperature period.

A through hole is formed in the non-embedded portion of the foundation beam provided with such a heat insulating material, and a cover body that is detachable from the outside of the building, that is, the outside of the foundation beam is formed in this ventilation port. It can be inserted. As a result, in summer when the temperature is high, by removing this cover from the ventilation opening, the ventilation function of the ventilation openings formed on the foundation beams connected in series provides good air circulation under the floor. Will be done.

Then, when the temperature is low or snow is generated, by inserting a lid into the ventilation port, each foundation beam has a structure without an opening, and the airtightness of the lower floor is secured, and The heat insulation effect of the entire foundation becomes good in combination with the heat insulation effect provided on the inner surface side of the foundation beam.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a view showing the structure of a foundation beam provided with a heat insulating material. The figure (A) is a front view, the figure (B) is a plan view, and the figure (C) is the same figure (A). 3 is a vertical sectional view taken along line BB in FIG.

As shown in the figure, the foundation beam main body 10 has a substantially rectangular parallelepiped shape, and is made of precast concrete in which reinforcing bars are arranged inside and the whole is constituted by concrete.

Further, as can be seen from FIG. 1B, the left and right ends thereof are formed to have a large wall thickness, and the recesses 12 that open to the sides are formed therein. The recesses 12 are used to satisfactorily connect the plurality of foundation beam main bodies 10 to each other. The recesses 12 are formed so as to face each other, and are formed by the two recesses 12. By arranging reinforcing bars in the space and solidifying the concrete by inflow, the foundation beam main bodies 10 are firmly connected to each other.

A heat insulating material 14 is provided on the entire inner surface of the foundation beam main body 10. The heat insulating material 14 is formed of, for example, expanded polystyrene foam.

Next, a ventilation port 16 is formed at a position slightly closer to the upper side when the foundation beam main body 10 is installed. The ventilation port 16 is formed so as to penetrate through the foundation beam main body 10 in the thickness direction, and a wire mesh 18 is stretched so as to prevent objects and animals from entering inside as shown in FIG. Has been. In this embodiment, one ventilation port 16 is formed in each foundation beam main body 10.

Next, FIG. 2 shows the configuration of the lid portion 20 inserted into the ventilation port 16. FIG. 2A is a plan view and FIG. 2B is a side view. There is.

As shown in the figure, the front end side of the lid body 20 on the insertion side into the ventilation port 16 is formed to be narrower in the vertical and horizontal directions than the base end 20b side where the handle 22a is formed. That is, the lid 20 has a tapered structure. With this structure, the user can easily insert the lid 20 into the ventilation opening 16 with the handle 22.

Regarding the material of the lid 20, a material that can close the ventilation port 16 with better airtightness when inserted into the ventilation port 16 is preferable. For example, it can be made of synthetic resin, rubber, or the like, and various materials can be used as long as it is a member whose weight and installation condition are secured so as not to easily come off due to wind or the like. .

FIG. 3 is an explanatory view showing an inserting operation of the lid body 20. As shown in the drawing, the lower part is inserted into the ventilation port 16 of the foundation beam main body 10 in the direction of arrow 400 from the outside. It is loaded. In addition, when it is necessary to ensure air circulation under the floor in the summer, the lid 20 can be removed and stored separately.

As described above, the lid 20 can be easily attached and detached at the outer position of the foundation beam. Therefore, it is possible to select either the function of securing the flowability of the air under the floor or the improvement of the heat insulating property and appropriately perform the insertion / removal work.

Further, since the foundation beam main body 10 can be formed in advance at the factory stage, the foundation beam construction work at the construction site is a work of continuously arranging the foundation beam main body at an appropriate position. By doing so, a basic structure can be achieved and the work of constructing the foundation part is made more efficient.

The present invention is not limited to the configuration of the above embodiment, and various modifications can be made within the scope of the present invention.

For example, in the above embodiment, one ventilation port 16 is formed for each foundation beam main body 10, but it is of course possible to form a plurality of ventilation ports 16.

Further, the shape of the ventilation port 16 is not limited to the rectangular shape, and it is also possible to use a circular shape or another shape.
