Description

The present invention relates to, for example, a building having a woody portion on an outer wall.

Conventionally, buildings using CLT (Cross Laminated Timber), which is made by laminating and adhering multiple wood boards so that the fiber directions are orthogonal to each other, have been popularized. However, when CLT is used for the outer wall, its weather resistance There is concern about low sex.

Therefore, it is conceivable to provide glass on the outside of the CLT via a space to form a double-skin structure.

However, this double-skin structure may cause dew condensation on the inner glass surface of the double-skin due to moisture absorption and desorption from the CLT. Maintenance may be impossible.

Therefore, if the space is made thicker, there is a problem that the effective floor area is reduced and the visibility of the CLT from the outside is also lowered.

The above is not limited to CLT, but is generally applicable to the case where a wooden portion is provided on the outer wall such as a wooden panel.

The present invention provides a building capable of increasing the effective floor area and improving the visibility of the wooden part from the outside while reducing the labor and the like related to maintenance when the wooden part is provided on the outer wall. The purpose is to provide.

In order to achieve the above object, the building according to the present invention is provided with a translucent wall through a space on the outside of the woody portion of the outer wall, surrounds and seals the space, and makes it possible to supply dry compressed air to the space. A discharge unit for discharging the dry compressed air and the dew condensation water generated in the space is provided below the space (claim 1).

In the above building, a check valve may be provided in the discharge portion (claim 2).

In the present invention, when a wooden part is provided on the outer wall, a building capable of increasing the effective floor area and improving the visibility of the wooden part from the outside can be achieved while reducing the labor and the like related to maintenance. can get.

That is, in the building of the invention according to each claim of the present application, by making the translucent wall, for example, transparent glass, the woody portion of the outer wall can be exposed to the outside. Further, if dry compressed air is supplied so that dew condensation does not occur in the space on a daily basis, the space can be made maintenance-free, and in this case, it is not necessary for a person to enter the space. It is also possible to reduce the thickness of the space, increase the effective floor area, and improve the visibility of the woody portion from the outside. Further, it is possible to reduce the pressure in the space by discharging the dry compressed air supplied into the space from the discharge unit. Further, even if dew condensation occurs in the space, the dew condensation water can be discharged from the discharge portion.

In the building of the invention according to claim 2, by providing the check valve, the intrusion of wind and rain or the like from the outside through the discharge portion to the inside of the space is prevented, so that dehumidification of the space is ensured. It is possible to plan.

(A) and (B) are a vertical cross-sectional view and a partially cut front view schematically showing the configuration of a main part of a building according to an embodiment of the present invention. It is a vertical sectional view schematically showing the structure of the main part of the building. It is an elevation view which shows roughly the structure of the frame and the wooden part of the building. It is explanatory drawing which shows the basic principle of the main part of the building roughly. It is explanatory drawing which shows the flow of the dry compressed air in the said building.

Embodiments of the present invention will be described below with reference to the drawings.

First, in the building according to this example, as can be grasped from the principle diagram shown in FIG. 4, a translucent wall 3 is provided outside the wooden portion 1 of the outer wall via the space 2, and the wooden portion 1 is provided with an appropriate member. The gap between the peripheral edge and the translucent wall 3 is closed (the space 2 is surrounded and sealed), the dry compressed air A is supplied to the space 2, and the dry compressed air A supplied into the space 2 and the space 2 are generated. Condensed water is discharged to the outside from a plurality of (five in the illustrated example) discharge units 4 provided below the space 2.

In such a building of this example, by using transparent glass, for example, the translucent wall 3 makes it possible to expose the woody portion 1 of the outer wall to the outside.

Further, in the building of this example, if the dry compressed air A is supplied so that dew condensation does not occur in the space 2 on a daily basis, the space 2 can be made maintenance-free, and in this case, a person is in the space 2. Since it is not necessary to enter the inside, it is possible to reduce the thickness of the space 2 to increase the effective floor area and improve the visibility of the woody portion 1 from the outside. Moreover, when the inside of the space 2 is not maintenance-free, it is rational to enable maintenance in the space 2 from the indoor side. However, for example, if all the wood parts 1 must be removed for that purpose, the wood parts Depending on the number and weight of 1, a great deal of labor is required to attach and detach all the woody portions 1, and the woody portion 1 cannot be structurally burdened. Therefore, it is conceivable to make it possible to remove only a part of the woody part 1, but in this case, in addition to complicating the structure, there is a risk that the maintenance of the entire space 2 will be insufficient, and the space 2 is thin. If you try to make it, the maintenance of the entire space 2 will become more difficult or impossible. From the above, it can be said that it is very significant to make the space 2 maintenance-free.

Here, since it is possible to reduce the pressure in the space 2 by discharging the dry compressed air A supplied into the space 2 from the discharge unit 4, the supply of the dry compressed air A causes the space 2 to have a high pressure. Therefore, it is possible to prevent the members around the space 2 from being damaged. Further, even if dew condensation occurs in the space 2, the dew condensation water can be discharged from the discharge unit 4.

Hereinafter, the building of this example will be described in detail.

As shown in FIGS. 1A and 1B, the woody portions 1 of this example are arranged in a checkered pattern on the outer wall of the building, and a space (diagonal line in FIG. 1A) is outside each woody portion 1. A translucent wall (glass plate in this example) 3 is arranged via the portion (2).

Here, the wood portion 1 of this example is formed of a wood surface material (wood panel material) such as the above-mentioned CLT, LVL (Laminated Veneer Lumber), laminated wood, plywood, etc., and as shown in FIG. 3, a pillar (for example). It is provided in a frame (in this example, a steel frame) 7 constructed of a frame (steel column formed of square steel pipe) 5 and a beam (for example, a steel beam formed of H-shaped steel) 6 and has a rectangular shape in front view. The thickness is almost the same as the beam width.

Then, as shown in FIG. 3, the wooden portion 1 is joined to the upper and lower beams 6 by a pull bolt 8 as a tensile force transmitting member and a bracket 9 as a shearing force transmitting member. That is, above and below the woody portion 1, an insertion hole into which the pull bolt 8 is inserted, a slit (groove portion) into which the bracket 9 is inserted, and the like are provided.

Further, as shown in FIG. 3, a cement-based hardened body (non-shrink mortar in this example) 10 is filled between the woody portion 1 and the beams 6 above and below the woody portion 1.

In this example in which the wood portion 1 is provided in this way, the seismic performance of the building is improved by transmitting the shearing force and bending moment between the wood portion 1 and the beam 6 via the pull bolt 8, the bracket 9, and the cement. The increase in the transmission efficiency of the bending moment by the cured body 10 contributes to the further improvement of the seismic performance. In addition, the cement-based hardened body 10 can absorb construction errors of the wood portion 1 and the beam 6, and can prevent heat transfer from the beam 6 to the wood portion 1.

As shown in FIGS. 1A and 2, the space 2 is sandwiched between the front surface of the woody portion 1 and the back surface of the transmission wall 3, and the gap between the peripheral edge of the woody portion 1 and the transmission wall 3 is transparent. The space 2 is closed by a member supporting the wall 3, a decorative plate 11 provided below the wooden portion 1, and the like, whereby the space 2 is sealed so that the outside air does not freely enter and exit the inside thereof.

Then, as shown in FIG. 3, the tip of a blower pipe (for example, a tube) 13 is arranged above the gaps 12 on the left and right of the woody portion 1, and the dry compressed air A is placed in the space 2 from the tip of the blower pipe 13. Can be supplied. The gap 12 is filled with a sealing material (not shown) with the blower pipe 13 left.

Here, on the upstream side of the blower pipe 13, as shown in FIG. 5, in addition to a device 15 such as a compressor for taking in outside air arranged on a predetermined floor such as the first floor, dehumidification to dehumidify the taken in outside air. Means, cleaning means (for example, filter) 16 for cleaning, dehumidifying means (for example, pressure reducing valve) 17 for appropriately reducing the pressure, and flow rate adjusting means (for example, throttle valve) for adjusting the flow rate of the dry compressed air A supplied to the space 2. Etc.) 18 is provided so that the air supplied to the space 2 is appropriately dried and pressurized. Then, the dry compressed air A reaches each floor from the predetermined floor through the blower pipe 19, further branches on each floor, and is sent to each room or a specific one or more rooms, and the blower pipe 13 in the room. Passes through the ceiling as shown in FIG. 1 (A), branches appropriately, and reaches the upper part of the left and right gaps 12 of the woody portion 1 as shown in FIG.

On the other hand, as shown in FIG. 2, each of the discharge portions 4 provided below the translucent wall 3 is provided with a check valve 14 so as to reach the inside of the space 2 from the outside through the discharge portion 4. Since such intrusion of wind and rain is prevented, it is possible to ensure dehumidification of the space 2.

In the building of this example having the above configuration, as described above, by supplying the dry compressed air A into the space 2, dew condensation can be prevented in the space 2, and if dew condensation occurs, the dew condensation can be prevented. Dehumidification (elimination) can be achieved.

Here, the dry compressed air A may be supplied to the space 2 on a regular basis, or may be irregularly supplied when dew condensation occurs in the space 2 or when dew condensation is likely to occur. For example, a water leakage sensor is provided in a portion below the space 2 that receives dew condensation, a discharge portion 4, or the like, and when the water leakage sensor detects dew condensation water as water leakage, the dry compressed air A receives the detection signal. If a control unit for supplying to the space 2 is provided, it is possible to automate the elimination of dew condensation.
