Description

[Detailed Description of the Invention] This invention relates to a ventilator used for discharging steam generated in a waterproof layer on the roof of a building.

As this type of decylinder, for example, Utility Model Application No. 54-3132
1 Waterproof layer ventilation described in Publication No. 1 is known.

Conventionally, this type of decapitalization cylinder is equipped with a mechanism to prevent rainwater from entering, but there is no mechanism for forcibly discharging steam generated from the waterproof layer, and the evaporated gas is simply released naturally. It was extremely inefficient because it was left to flow out to the outside due to convection phenomena.

This invention is an improvement on the above, and embodiments thereof will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a cross-sectional view of one embodiment of this invention.

In the figure, reference numeral 1 denotes a cylinder of a decoupling cylinder, which is placed on the upper surface of a slab concrete A or in a waterproof layer B of a laminated structure.

Reference numeral 2 denotes an outer cylinder, which is fixed to the upper end of the inner cylinder 1 and whose base is waterproofed.

Reference numeral 3 denotes a cap for preventing rainwater from entering, and is fixed to the outer peripheral surface of a protrusion 4 formed at the upper end of the outer cylinder 2.

A shaft 5 is fixed to the center of the cap 2, windmills 6 of various shapes are fixed to the exposed side of the shaft 5, and rotary vanes 7 during exhaust are fixed to the outside of the outer cylinder.

Reference numeral 8 denotes a bearing member attached to the open end of the outer cylinder 2 in order to prevent rotational deviation of the shaft 5, and is provided with a through hole serving as an air passage.

Note that if the shaft 5 is sufficiently fixed to the cap 3, the shaft bearing member 8 may not be provided.

Note that the shape and size of the exhaust rotary vane 7 are not limited.

As shown in Fig. 1, the inner cylinder 1 has a cylindrical part and a hem extending at the bottom thereof, and a mounting protrusion is formed in the vertical direction on the outer surface from the cylindrical part to the hem and on the lower surface of the hem. has been done.

Due to the presence of these protrusions, an air passage is formed between the cylindrical part and the outer cylinder 2, and at the hem part, for example, a waterproof sheet as a waterproof layer comes into close contact with the outer surface or lower surface of the inner cylinder 1. The air flow path is prevented from being blocked.

FIG. 2 shows another embodiment of this invention,
A mechanism is provided to prevent rainwater from entering through the shaft 5 of a wind turbine or the like.

That is, the upper surface of the cap 3 is inclined in the direction of the manufacturing line and the shaft 5
A convex portion 3a is formed around the through hole through which the material passes.

On the other hand, a cap 5a having a cross-sectional opening shape is provided on the shaft 5 side to cover the convex portion 3a on the cap 3 side.

By designing in this manner, it is possible to effectively prevent rainwater and the like from entering the desorption cylinder.

Further, in this type of destacking, exhaust efficiency is not required, such as that of a ventilation fan or a septic tank ventilator, but on the contrary, it is necessary to design the shape and size of the wind turbine, etc., taking into consideration prevention of damage caused by strong winds.

Incidentally, the structure for mounting the wind turbine, etc. is not limited. Also, the third
As shown in the figure, a cover member 9 may be provided around the wind turbine 6.

Further, the wind turbine 8 may be installed horizontally, or may be changed in position according to the wind direction.

Since this device is constructed as described above, the moisture remaining in the waterproof layer evaporates when the waterproof layer is heated.
Since the steam generated in the waterproof layer is forcibly discharged to the outside by the rotation of the windmill and the exhaust rotary vanes, it is possible to remove the steam generated in the waterproof layer more efficiently than with conventional deventing.

[Brief explanation of the drawing]

8 indicates the bearing member, 9 indicates the cover member, A indicates the slab concrete, and B indicates the waterproof layer.

Claims (1)

[Scope of utility model registration request] An inner cylinder consisting of a cylindrical part with vertically protruding ridges on at least its outer surface and a hem extending at its lower end, and an external exhaust rotary blade rotated by a windmill are disposed and airflow is provided. The outer cylinder is made up of a cylindrical part whose upper end is covered with a cap having a channel and a lower quarter extending around the lower end, and the inner cylinder is buried in a waterproof layer. When the outer cylinder is placed on the upper part and the upper surface of at least the lower quarter of the outer cylinder is covered with waterproof coating, steam generated in the waterproof layer on the bottom side of the inner cylinder will be removed from the bottom of the hem, inside the inner cylinder, and inside the outer cylinder.・Steam generated in the waterproof layer below the lower parts of the outer cylinder on the upper surface of the inner cylinder through the air flow path of the cap and the air flow path formed at the joint between the inner cylinder and the outer cylinder.
A de-cylinder is characterized in that the air is forcibly discharged to the outside by an exhaust vane through the inside of the outer cylinder and the air flow path of the cap.
