Description

This disclosure relates to entrance door structures.

In recent years, buildings have become increasingly airtight, and work to increase the airtightness of interior spaces is often carried out not only in new buildings but also in the renovation of existing buildings. In highly airtight buildings, humidity-controlling building materials are installed not only in living rooms but also in the walls and ceilings of entrance halls to prevent condensation and other problems (see, for example, Patent Document 1). For example, panel-shaped humidity-controlling building materials are used as humidity-controlling building materials installed on walls and ceilings.

Japanese Patent Application Laid-Open No. 2001-32641

When installing humidity-regulating building materials at the entrance of a building during renovations, the installation is time-consuming because adhesive must be applied to the humidity-regulating building materials and then they are attached to the walls and ceiling.

The purpose of this disclosure is to provide an entrance door structure that allows humidity-control building materials to be easily installed in the entrance space.

In order to achieve the above-mentioned objective, the entrance door of the present disclosure comprises an entrance door installed in an entrance space, and a humidity-regulating building material fixed along the surface of the entrance door and regulating the humidity of the entrance space, wherein the entrance door is a door with a sleeve panel having a door body and a sleeve panel, and the humidity-regulating building material is fixed along the surface of only the sleeve panel out of the door body and the sleeve panel .
In order to achieve the above-mentioned object, the entrance door of the present disclosure comprises an entrance door installed in an entrance space, and a humidity-regulating building material fixed along the surface of the entrance door and regulating the humidity of the entrance space, wherein the entrance door is a parent-child door having a parent door and a child door, and the humidity-regulating building material is fixed along the surface of only the child door of the parent door and the child door.

FIG. 1 is a front view of an entrance door structure according to a first embodiment. FIG. 1 is a perspective view of a humidity-regulating building material. FIG. 1 is a front view of an entrance door structure according to a first embodiment.

(First embodiment)
As shown in Figure 1, the entrance door structure 1 according to the first embodiment is a structure of an entrance door 2 installed at the entrance of a building. The horizontal direction along the wall portion 11 on which the entrance door 2 is installed is defined as the width direction.

The entrance door structure 1 comprises an entrance door 2 and a panel-shaped humidity-control building material 3 that is fixed to the interior surface of the entrance door 2 and controls humidity in the entrance space 12. The entrance door 2 comprises a frame 21 provided at the opening 13, a door body 22 supported on the frame 21 so that the opening 13 can be opened and closed, and a sleeve panel 23 that closes a portion of the opening 13. The entrance door 2 is a door with a sleeve panel 23 provided on one side. The door body 22 is located on one side in the width direction, and the sleeve panel 23 is located on the other side in the width direction. The sleeve panel 23 is fixed to the frame 21 without opening or closing the opening 13. A magnet can be attached to the interior surface 23a of the sleeve panel 23. For example, the interior surface 23a of the sleeve panel 23 may be formed from a steel plate (a material to which a magnetic member can be attached), or a steel plate may be attached to the interior surface 23a of the sleeve panel 23.

As shown in FIG. 2, the humidity-conditioning building material 3 comprises a rectangular, plate-shaped humidity-conditioning building material panel 31 (humidity-conditioning building material body) and a magnetic sheet 32 (magnetic member) provided on one surface 31a of the humidity-conditioning building material panel 31. Multiple magnetic sheets 32 are provided on one humidity-conditioning building material panel 31. The multiple magnetic sheets 32 are fixed to one surface 31a of the humidity-conditioning building material panel 31 with adhesive, double-sided tape, or the like. The other surface 31b of the humidity-conditioning building material panel 31 is a finished surface, which may be patterned or printed.

The humidity-control building material panel 31 is manufactured by mixing humidity-controlling raw materials such as clay from volcanic pumice layers, diatomaceous earth, acid clay, activated clay, zeolite, halloysite, and sepiolite with clay, silica stone, pottery stone, rosewood, feldspar, and other glassy components, extruding or pressing the resulting molded body, and firing it. The molded body can be glazed and then fired, or bisque-fired, glazed, and then fired again. Glazing is not a required component. Other examples of humidity-controlling building materials 3 include those made primarily from activated carbon or diatomaceous earth and molded into plates. Humidity-controlling performance refers to the ability of the humidity-controlling material to absorb and release moisture from the air depending on the humidity of the space inside the building in which it is installed.

The humidity-conditioning building material 3 is attached to the indoor-side surface 23a of the sleeve panel 23 with the surface (one surface 31a of the humidity-conditioning building material panel 31) on which the magnetic sheet 32 is provided facing the indoor-side surface 23a of the sleeve panel 23. The other surface 31b of the humidity-conditioning building material panel 31 faces the indoor side. This secures the humidity-conditioning building material 3 to the indoor-side surface 23a of the sleeve panel 23. The width dimension of the humidity-conditioning building material 3 is slightly smaller than the width dimension of the sleeve panel 23. The humidity-conditioning building material 3 is attached within the width dimension of the sleeve panel 23. In this embodiment, four humidity-conditioning building materials 3 are arranged vertically on the sleeve panel 23. A gap may be provided between vertically adjacent humidity-conditioning building materials 3.

The sleeve panel 23 to which the humidity-conditioning building material 3 is fixed may be a new sleeve panel installed together with the humidity-conditioning building material 3, or may be an existing sleeve panel, as long as the magnetic sheet 32 of the humidity-conditioning building material 3 can be attached to the interior-facing surface 23a.

The entrance door structure 1 is structured so that a humidity-controlling building material 3, which controls humidity in the entrance space 12, is attached to the surface of the sleeve panel 23 of the entrance door 2. The entrance door structure 1 makes it easier to install the humidity-controlling building material 3 in the entrance space 12 than if the humidity-controlling building material 3 were attached to the wall 11 or ceiling of the entrance space 12. The humidity-controlling building material 3 can be easily fixed to the sleeve panel 23 with a magnetic sheet 32. Because the humidity-controlling building material 3 is fixed to the sleeve panel 23 with the magnetic sheet 32, it can also be easily removed.

The humidity-control building material 3 is fixed along the surface of the sleeve panel 23, which does not move when the front door 2 is opened or closed. This prevents the humidity-control building material 3 from shifting or being damaged by the impact of opening or closing the front door 2.

The humidity-control building material 3 is detachable from the entrance door 2. This allows the humidity-control building material 3 to be easily replaced depending on the required level of humidity control and the design of the entrance space 12.

Second Embodiment
The door structure 1B according to the second embodiment includes a main door 2B, which is a double door.

The front door 2B has a frame 21B provided in the opening 13, and a main door 24 and a sub door 25 supported on the frame 21B so that the opening 13 can be opened and closed. The main door 24 and the sub door 25 are arranged side by side in the width direction. The main door 24 is arranged on one side of the frame 21 in the width direction, and the sub door 25 is arranged on the other side of the frame 21 in the width direction. The main door 24 opens the opening 13 during normal entry and exit. The sub door 25 is normally fixed to the frame 21 with a French fastener or similar, and opens the opening 13 together with the main door 24 when the opening 13 is to be opened widely, such as when large furniture is being brought in. The humidity-controlling building material 3 is attached to the interior surface 25a of the sub door 25. The magnetic sheet 32 of the humidity-controlling building material 3 can be attached to the interior surface 25a of the sub door 25. For example, the interior surface 25a of the sub-door 25 may be made of steel plate (a material to which a magnetic member can be attached), or a steel plate may be attached to the interior surface 25a of the sub-door 25. In the second embodiment, eight humidity-control building materials 3 are arranged vertically. The size and arrangement of the humidity-control building materials 3 may be set as appropriate.

The entrance door structure 1B achieves the same effects as the first embodiment. In the entrance door structure 1B, the humidity-control building material 3 is fixed along the surface of the sub-door 25, which is opened and closed less frequently. The entrance door structure 1B prevents the humidity-control building material 3 from shifting or being damaged by the impact of opening and closing the main door 24.

The present disclosure is not limited to the above embodiment and can be modified as appropriate. For example, instead of being fixed to the entrance door 2 by a magnetic sheet 32, the humidity-control building material 3 may be fixed by being fitted into a recess formed on the surface of the entrance door 2.

In the above embodiment, the humidity-controlling building material 3 is fixed to the interior surface 23a of the sleeve panel 23 or the interior surface 25a of the sub-door 25. Alternatively, the humidity-controlling building material 3 may be fixed to the door body 22 of a door with a sleeve panel or the main door 24 of a main-door-sub-door. The humidity-controlling building material 3 may also be fixed to the exterior surface of the front door 2. The front door 2 may be a sliding door, double door, single door, etc., and the humidity-controlling building material 3 may be fixed to the door body 22 of such a sliding door, double door, or single door.
