Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a ventilation window attached to a ventilation opening of a cloth foundation.

[0002]

[Prior art]

 Ventilation openings are formed in the fabric foundation of the building, and for the purpose of preventing the entry of small animals, ventilation openings with cast vertical grids are usually built in the opening. Traditionally, this type of ventilation frame is embedded in concrete at the stage of forming the fabric foundation. Therefore, after that, the inside of the floor cannot be inspected using the ventilation port. Moreover, since the effective opening area of the ventilation frame is also predetermined, the structure cannot be adjusted.

[0003]

[The purpose of the device]

 An object of the present invention is to allow the ventilation opening to be opened as needed and also to adjust its effective opening area.

[0004]

[Solution of the device]

 Based on the above-mentioned object, the present invention forms a ventilation window for a foundation by an outer frame made of a steel plate incorporated into an opening for a fabric foundation and an inner frame incorporated inside the outer frame. The outer frame has a lower lower plate on the outer side and a water return plate on the inner side of this lower plate, and the inner frame is positionally adjustable with respect to the opening of the outer frame and detachable by fixing means. It is installed. The opening surface of the inner frame can be opened and closed as a warrior type ventilation opening by the ventilation holes of the two slide type face plates provided in the inner frame. The back side of the face plate is divided into an inner side and an outer side by a insect screen.

【Example】

 1 to 6 show the structure of a ventilation window 1 for a foundation of the present invention. The foundation ventilation window 1 is composed of an outer frame 2 and an inner frame 3. The outer frame 2 is made of a steel plate and is a frame in which an upper plate 4, left and right side plates 5, 6 and a lower plate 7 are combined in a rectangular tubular shape. The upper plate 4, the side plates 5, 6 and the lower plate 7 are An edge plate 8 projecting to the outer peripheral side is integrally formed at the outer (front side) edge part, and the upper plate 4 and the side plates 5 and 6 are similarly formed at the inner (rear side) open end part. An edge plate 9 that projects to the outer peripheral side is integrally formed. Further, the lower plate 7 is inclined downward in the outer direction and higher in the inner direction, and is integrally formed with the water return plate 10 which rises upward at the inner edge portion and is folded back inward (in the front direction). Is formed. In addition, on the upper surface of the lower plate 7, protrusions 11 for contacting the inner frame 3 are formed, for example, at two positions.

Next, the inner frame 3 has a size to be incorporated into the outer frame 2, and is a pressed product of, for example, a stainless plate, and is made up of the upper member 12, the left and right vertical members 13, 14 and the lower member 15. Are combined in a rectangular frame shape, and they are narrowed down so as to be tapered on the inner side, and the frame 16 is integrally formed on the opening surface side four rounds. In addition, the upper and left and right frame 16 are formed as inclined surfaces (tapered surfaces) that enter the inside of the outer part to prevent intrusion of rainwater while hitting the outer surface of the cloth foundation, but the lower side The frame 16 has a vertical direction so as to facilitate the flow of rainwater from the inside, and does not form a tapered surface.

Then, screws 18 are attached to long attachment holes 17 formed in the horizontal direction in the left and right vertical members 13, 14 of the inner frame 3, and these are attached to the side plates 5, 6 of the outer frame 2. By being screwed into the nut 19 attached to the inner frame 3, the inner frame 3 can be detachably combined with the outer frame 2 in a state in which the position can be adjusted in the horizontal direction, that is, the thickness of the cloth foundation, that is, the depth direction. . The opening surface of the inner frame 3 is, as an example, a face plate 20 that is integral with the upper member 12, the vertical members 13, 14 and the lower member 15, and is provided with ventilation holes 21 that are long in the vertical direction and are formed in two rows in the horizontal direction. The inside and the outside communicate with each other.

Further, on the back side of the face plate 20, a face plate 22 having a ventilation hole 23 of the same shape as the ventilation hole 21 is formed in the face plate 20, and a horizontal elongated hole 24 and a knob screwed into the face plate 22. It is attached by a screw 25 so that the position can be adjusted in the horizontal direction. As a result of such a structure, the two face plates 20 and 22 are of a sliding type on the opening surface of the inner frame 3, and the ventilation holes 21 and 23 form a warrior type ventilation port. Then, an insect screen 26 is attached to the back side of the face plate 22. The insect screen 26 is fitted on the back surface of the face plate 22 by a wire frame 27. It should be noted that the face plate 22 is placed in the groove of the receiving member 28 attached to the lower member 15 and the holding member 29 attached to the upper member 12 before the inner frame 3 is assembled to the outer frame 2 in the lateral direction. It is a model that can be attached and detached freely.

The outer frame 2 having the above structure is incorporated in a ventilation opening portion of the cloth foundation when the cloth foundation of the building is solidified with concrete. Further, the inner frame 3 is incorporated inside the outer frame 2 when the outer frame 2 is incorporated into the cloth foundation or after the outer frame 2 is incorporated, and is attached by screws 18 at an appropriate depth position. In this way, the ventilation opening of the cloth foundation is divided into the inner side and the outer side by the two face plates 20 and 22, and the effective opening area thereof is the side face of the movable face plate 22 with respect to the fixed face plate 20. By moving in the (horizontal) direction, it can be adjusted to the fully closed or fully open state.

Moreover, since the openings of the ventilation holes 21 and 23 are partitioned by the insect net 26 on the back side, small harmful insects such as termites cannot pass through the openings. . Since the projections 11 are present on the lower plate 7 of the outer frame 2 when the inner frame 3 is incorporated inside the outer frame 2, the lower material 15 of the inner frame 3 does not adhere to the lower plate 7. Therefore, even if rainwater enters this part, the rainwater flows down on the upper surface of the lower plate 7 and passes through the gap between the lower plate 7 and the lower member 15 and the gap between the edge plate 8 and the frame 16. , Discharged to the outside of the foundation.

[0011]

[Effect of device]

 The present invention has the following advantages. Since the inner frame 3 is detachable from the outer frame 2 and is separable, when only the outer frame 2 is fixed to the cloth foundation and then the inner frame 3 is assembled to the outer frame 2, At the stage of assembling the outer frame 2 to the ventilation port of the foundation, the inner frame 3 does not get in the way and is not deformed, so that the finished state is good. Further, since the lower plate 7 of the outer frame 2 is inclined and the water return plate 10 is formed there, even when only the outer frame 2 is attached or when the inner frame 3 is assembled to this outer frame, There is no intrusion of rainwater inside the cloth foundation, that is, under the floor, and high humidity inside the floor can be prevented.

Furthermore, when the inner frame 3 is assembled to the outer frame 2, the effective opening areas of the ventilation holes 21 and 23 can be adjusted by shifting the positional relationship between the two face plates 20 and 22. The air flow rate can be adjusted according to the local weather conditions, environment and four seasons. This ensures proper conditions under the floor. Moreover, since insect repellent nets 26 are attached to the rear sides of the ventilation holes 21 and 23 of the face plates 20 and 22, termites and other harmful pests cannot enter the underfloor, and damage to them can be prevented. Further, since the inner frame 3 can be detached from the outer frame 2 as needed, regular spraying of the disinfectant and internal inspection can be facilitated by utilizing the entire opening area of the outer frame 2.
