Description

  The present invention relates to a daylighting structure that can easily apply a daylighting structure to an existing roof and can improve indoor daylighting, and a construction method therefor.

In recent years, attempts have been made to improve indoor daylighting and reduce indoor lighting and heating for the purpose of preventing global warming. As a roof structure provided with a conventional daylighting section, it is generally composed of a trough part, that is, a substantially flat bottom surface part and inclined surface parts located on the left and right sides thereof, with respect to a folded plate roof board generally formed of a metal plate material. A method is known in which a U-shaped part is formed of a light-transmitting synthetic resin plate, a seam fastening portion or the like is formed of a metal plate material, and a roof plate in which these are integrated is used (see, for example, Patent Document 1). Yes.
In addition, for the purpose of preventing the fall of condensed water, there is also a method of arranging a translucent folded plate having crests and troughs up and down at a predetermined interval to make a daylighting unit (for example, see Patent Document 2). Proposed.
Furthermore, it replaces with the fitting cover material arrange | positioned in the peak part top part of the folded-plate roof which has a peak part and a trough part, and attaches the lighting frame which assembled | attached the translucent board to the frame (for example, refer patent document 3). ) Has also been proposed.

Japanese Patent Laid-Open No. 11-93335 JP 2001-49807 A JP 2004-137824 A

  However, in the method of Patent Document 1, a part of the roof plate is formed of a light-transmitting synthetic resin plate, and the light-transmitting roof in which the metal plate material and the light-transmitting synthetic resin plate are integrated. Since it is a method of laying a board, it is limited to new roof construction, and was not applied to an existing roof. In addition, both the method of Patent Document 2 and Patent Document 3 are basically developed for a new roof, and when applied to an existing roof, a roof shape or fitting with a predetermined size is used. The cover material (width interval) could not be handled.

  Then, this invention aims at proposing the lighting structure which can apply a daylighting structure easily to an existing roof, and can improve indoor daylighting, and its construction method.

  The present invention has been proposed in view of the above, and is a daylighting structure in which a daylighting portion is provided in a mountain-shaped portion constituting an existing folded-plate roof, and the mountain-shaped portion of the existing folded-plate roof is constructed. The left and right inclined portions are cut to form an open portion, and a groove-shaped mounting portion to be sandwiched and attached to each cutting edge, a vertical portion extending upward from the groove-shaped mounting portion, and the vertical portion from the cutting edge And a fixed receiving portion extending outwardly, and a light-transmitting member is fixed to the fixed receiving portion of the receiving member so as to cover the open portion. It is about.

  The present invention also proposes a daylighting structure in which the left and right receiving bar members are connected by a reinforcing member in the daylighting structure.

  Furthermore, the present invention is a construction method of a daylighting structure in which a daylighting portion is provided in a mountain-shaped portion constituting an existing folded-plate roof, and cuts right and left inclined portions that construct the mountain-shaped portion of an existing folded-plate roof A first step of forming an open portion, a groove-like attachment portion that is sandwiched and attached to each cutting edge formed in the first step, and a vertical portion that extends upward from the groove-like attachment portion And a second step of fixing the receiving bar members each having a vertical receiving part extending outward from the cutting edge, and a translucent member of the receiving bar member so as to cover the open part. The construction method of the lighting structure characterized by implementing the 3rd process attached to a fixed receiving part is also proposed.

  The daylighting structure of the present invention can be easily applied to an existing roof, can improve indoor daylighting, and can reduce indoor lighting and heating in winter.

  In addition, when the left and right receiving bar members are connected by a reinforcing member, the edge of the open portion is prevented from expanding and falling, and the strength of the folded plate roof is not reduced, and the indoor daylighting is improved. be able to. In this case, the receiving bar member and the reinforcing member may be integrally formed in advance and disposed in the second step, or may be separately formed and the receiving bar member is disposed in the second step. After that, the reinforcing member may be arranged so as to straddle the left and right receiving bar members.

  Furthermore, in the construction method of the daylighting structure according to the present invention, both the first step of cutting the inclined portion of the existing folded-plate roof and the second step of fixing the receiving member to the cutting edge, Since each of the steps 3 can be performed very easily, the practical value is extremely high.

The 1st process in the construction method of the lighting structure of this invention cut | disconnects the top part which constructs the mountain-shaped part of the existing folded-plate roof, and a right-and-left inclination part, and forms an open part. This open part becomes a daylighting part.
The existing folded plate roof to which the present invention is applied is formed by laying a longitudinally-sheathed exterior material having a mountain part and a valley part, and generally has a strength that allows an operator to walk on the upper surface. It can be applied to existing folded-plate roofs of various dimensions, and it may be a gouge fastening type in which the side edges of the left and right exterior materials are fastened and connected at the top of the mountain, or a cover material is attached to the top of the mountain A fitting type may be used.

In the second step of the present invention, a receiving bar member is attached to each cutting edge formed in the first step.
The receiving bar member used in the present invention includes a groove-shaped attachment portion that is sandwiched and attached to the cutting edge of the existing folded plate roof, a vertical portion that extends upward from the groove-shaped attachment portion, and the vertical portion that is described above. A fixed receiving portion extending outward from the cutting edge.
It is desirable that the groove-like attachment portion is attached with an elastic material or the like interposed so as to be stably attached to the cutting edge. The groove-shaped attachment portion may be substantially parallel (substantially U-shaped) or may have a narrow opening portion. Further, one (outer side) of the groove-shaped mounting portion may be a separate body. In this case, it becomes easy to cope with the thickness of the existing folded-plate roof material or the presence or absence of the backing material.
The shape of the vertical portion is not particularly limited, and deformation for fine adjustment in the width direction may be performed.
The fixed receiving portion is a portion to which a reinforcing portion and a translucent member, which will be described later, are attached, and extends outward from the cutting edge of the existing folded plate roof. Even if the water enters the rainwater, the rainwater is led to the inclined portion outside the cutting edge and drained.
This receiving member is made of metal, hard synthetic resin, etc., and has a strength capable of fixing screws, etc., and particularly if it can provide a strength capable of supporting a translucent member described later. It is not intended to limit. Further, the receiving bar member may be formed integrally with a reinforcing member to be described later, or may be configured separately. As will be described later, the reinforcing member is arranged so as to be installed between the receiving beam members so that the interval between the receiving beam members is maintained appropriately and firmly. Therefore, the receiving member and the reinforcing member are integrally formed. The case where the right and left receiving bar members are integrally formed (the portion to be connected serves as a reinforcing portion (material)) refers to the case where the right and left receiving bar members are integrally formed. Moreover, you may make it arrange | position previously what connected the left and right receiving bar member with the reinforcing member, and the receiving bar member and the reinforcing member in this case may be comprised by the different body (different material).

The left and right receiving bar members may be connected by a reinforcing member.
Specifically, as described above, the receiving bar member and the reinforcing member may be formed integrally with each other, or may be configured separately. In the former case, both members may be integrally connected in advance. In the latter case, after the second step, a step of arranging the reinforcing member so as to straddle the left and right receiving bar members is performed. Since the former case conforms to the description of the receiving member in the second step, the latter case will be described below.
This reinforcing member is arranged so as to be installed between the receiving bar members so as to maintain the interval between the receiving bar members appropriately and firmly, and to prevent the edge of the open part from expanding and falling. For example, the material and configuration are not particularly limited. This reinforcing member is molded by pressing or extruding a metal or hard synthetic resin, and the transmission range can be further increased by using a light-transmitting material. For example, in a member having translucency such as a hard resin molded body, it is preferable to use a material having a large width and thickness in order to increase the strength. In order to reduce the light shielding portion, it is preferable to use a member having a small width and thickness. Further, this reinforcing member may be provided at least at the end of the open portion, and may be provided at a position other than the end portion (for example, intermediate) depending on various conditions such as the length and width of the open portion. In such a case, as the reinforcing member, a plurality of types of, for example, a metal member and a hard resin member may be appropriately combined (preferably the end portion is made of a non-translucent metal member. The middle is made of translucent hard resin). Similarly, for the receiving bar member, a metal and a hard synthetic resin may be appropriately selected and used in accordance with various conditions.

In the third step of the present invention, a translucent member is attached to the fixed receiving portion of the receiving bar member so as to cover the open portion.
The translucent member used in the present invention has translucency (transparency) to such an extent that it can be daylighted, and has water shielding (non-permeability) to such an extent that rainwater can be prevented from entering. For example, the material and configuration thereof are not particularly limited, and glass such as glass and netted glass, or a transparent hard resin molded body such as polycarbonate or acrylic is used. When using glass, a gasket for holding the side edge, a frame for mounting, and the like are required. However, when using a transparent hard resin molding, they are not basically required. .
In particular, when a support member is attached to an existing folded plate roof and the back surface of the translucent member is supported by the support member, the mounting stability of the translucent member is improved.
Furthermore, in the case where a supporting member molded with synthetic resin having water-stopping properties is attached to an existing folded plate roof located on the water side of the opening portion, intrusion of rainwater into the opening portion is caused by this supporting member. Therefore, the rain performance of the daylighting structure is further improved.

  The daylighting structure of the present invention constructed in this way can be easily applied to existing roofs, can improve indoor daylighting without reducing the strength of the folded roof, and can be used for indoor lighting and winter heating. It can also be used for mitigation.

  1 to 3 are examples in which the daylighting structure of the present invention is applied to an existing folded-plate roof of a gouge-tightening type, and left and right inclined portions B and B for constructing a mountain-shaped portion A of an existing folded-plate roof are shown. The opening 1 is formed by cutting, and the receiving bar members 2 and 2 are fixed to the cutting edges b and b, respectively, and the reinforcing members are straddled across the fixed receiving parts 24 and 24 of the left and right receiving bar members 2 and 2. 3 and a translucent member 4 is attached so as to cover the open portion 1.

  Fig.2 (a) is sectional drawing which shows the 1st process in the construction method of the lighting structure of FIG. 1, and is the upper part of the right-and-left inclination parts B and B which construct the mountain-shaped part A of the existing folded-plate roof Is cut to form the opening 1. In FIGS. 1A and 2A, X indicates an opening dimension, and Y indicates a notch dimension. That is, the notch dimension Y is obtained according to the preset opening dimension X, and the cutting operation is performed accordingly.

As shown in FIG. 2A, the receiving bar member 2 of the illustrated embodiment is provided with a substantially U-shaped groove-shaped mounting portion 21 at the lower end, and extends upward (inward (opening portion 1 side)). A vertical portion 23 bent in a substantially right-angled shape is provided, and a fixed receiving portion 24 whose upper end is further bent outward is provided.
When the receiving member 2 is attached to the cutting edge b of the inclined portion B as described above, the cutting edge b is positioned in the groove-like attachment portion 21 and fixed with a fixing tool 22 such as a screw. .

Subsequently, the reinforcing member 3 is disposed so as to straddle the left and right receiving bar members 2 and 2 attached in the second step.
The reinforcing member 3 in the illustrated embodiment includes a support portion 31 that is inclined downward from the center toward the left and right, and fixed portions 32 and 32 that are further inclined downward on the left and right side ends. The support portion 31 has a configuration in which the front end and the rear end are bent into a flange shape to improve the bending strength.
And it arrange | positions so that the fixing | fixed parts 32 and 32 of this reinforcement member 3 may overlap with the fixed receiving parts 24 and 24 of the said receiving-piece members 2 and 2. FIG.

Thereafter, as a third step, the translucent member 4 is attached to the fixed receiving portions 24 and 24 of the receiving bar members 2 and 2 so as to cover the open portion 1.
The translucent member 4 of the illustrated embodiment is a transparent hard resin molded body made of polycarbonate molded long in the direction of water flow as shown in FIG. 3, and is a translucent surface portion 41 inclined downward from the center to the left and right. And the left and right side ends are further inclined downward, and the tip end thereof is folded downward. The translucent surface portion 41 has a configuration in which a plurality of hollow chambers are continuous in the width direction.
The decorative surface portion 41 of the translucent member 4 is disposed so as to cover the open portion 1 and to be supported by the support portion 31 of the reinforcing member 3, and the fixed surface portions 42 and 42 are disposed on the receiving member 2. It arrange | positions so that it may overlap with the 2 fixed receiving parts 24 and 24. In FIG. 1B, V represents a notch range in the flow direction, and W represents an overlap dimension. That is, the translucent member 4 covers the notch range V and is superposed on the existing roof by the overlap dimension W (no notch) and is installed. At that time, support members 5 and 5 were attached on the existing roof (not cut out), and the back surface of the translucent member 4 was supported by the support member 5.

The daylighting structure of the present invention thus constructed is reinforced both in the first step of cutting the inclined portion B of the existing folded plate roof A and in the second step of fixing the receiving member 2 to the cutting edge b. Both the process of attaching the member 3 and the third process of attaching the translucent member 4 can be carried out very easily, can be easily applied to the existing roof A, and the strength of the folded roof A is not reduced. It is possible to improve the daylighting performance. Then, it can be used to reduce indoor lighting and heating in winter.
Further, in the illustrated embodiment, the water stop material 5 is attached to the existing folded plate roof A, and the water stop material 5 prevents water from entering the back surface of the translucent member 4, so that rain performance is reduced. There is no.

  The embodiment of FIG. 4 is an example in which the translucent member 4 is connected in series by a joint member 6 in the longitudinal direction. The joint member 6 has a structure in which left and right side ends of a support portion 61 that is inclined downward from the center to the left and right are further inclined downward, and a fixing portion 62 is formed with its tip folded downward. Are fixed to the fixed receiving portions 24, 24 of the receiving bar members 2, 2. In addition, the joint member 6 is not particularly limited in material and configuration, like the reinforcing member 3 disposed inside the translucent member 4, and has translucency such as a hard resin molded body. In order to increase the strength, it is preferable to use a member having a large width and thickness. In the case of a high-strength non-light-transmitting (light-blocking) member such as a metal molded body, the light-blocking portion is reduced. It is preferable to use one having a small width and thickness. Since the other configuration is exactly the same as the embodiment of FIG. 1, the same reference numerals are given and description thereof is omitted.

  In this embodiment, the joint member 6 is disposed across the outer sides of the plurality of translucent members 4, 4, but the reinforcing member 3 is assigned to the inner side (back side) of the interval between the translucent members 4, 4. Therefore, the connecting portions of the translucent members 4 and 4 can be held so as to be sandwiched from the inner side (reinforcing member 3) and the outer side (joint member 6), and do not become weak points.

  The embodiment of FIG. 5 is an embodiment in which a lighting structure is applied to the existing roof A similar to the embodiment of FIGS. 1 to 3, but glass is used without using a transparent hard resin molded body as a translucent member. It is the Example using.
