Abstract

PROBLEM TO BE SOLVED: To provide a support structure of a plate-like body for a window in which distortion amounts of a vertical member and a horizontal member can be suppressed, even when front dimensions of the vertical member and the horizontal member are reduced, even in a plate-like body for a window with a large area, namely, with a heavy weight.SOLUTION: In a window glass unit 10, a dead-weight receiving member 18 supporting multiple glass G is disposed in a connection part 20 of a vertical member 12 and a horizontal member 14, the vertical member 12 and the horizontal member 14 are connected via the dead-weight receiving member 18, and a dead-weight of the multiple glass G is supported by the dead-weight receiving member 18 disposed in the connection part 20 of the vertical member 12 and the horizontal member 14. Thus, even in a plate-like body for a window with a large area, namely, with a heavy weight, even when front dimensions of the vertical member 12 and the horizontal member 14 are reduced, distortion amounts of the vertical member 12 and the horizontal member 14 by the dead weight of the multiple glass G can be suppressed. Since a force in an axial direction is charged by the horizontal member 14 in the window glass unit 10, deformation of the vertical member 12 can be prevented. Therefore, since section stiffness required for the vertical member 12 can be set lower, the front dimension of the vertical member 12 can be reduced.

Description

  The present invention relates to a support structure for a window plate.

  The curtain wall construction method, which is one of the building outer wall construction methods, has a construction method called a unit type and a knockdown type. The former construction method is as follows: a window plate body is pre-installed at a factory in a rectangular window frame composed of vertical members (also referred to as vertical frames or verticals) and horizontal members (also referred to as horizontal frames or plain). It is a construction method in which the unit is assembled and unitized, and this unit (support structure for a plate for windows) is carried into a construction site to construct a curtain wall. On the other hand, the latter carries vertical and cross members into the construction site, joins the vertical and cross members at the construction site, assembles the window frame, attaches the window plate to the window frame, and installs the curtain wall. It is a construction method to build. Patent Documents 1 to 3 and the like are known as the former example, and Patent Document 4 and the like are known as the latter example. The unit using a glass plate as the window plate is a window glass unit, and a curtain wall formed by connecting a plurality of window glass units is a glass curtain wall.

  Today's window glass units tend to make the window frame slimmer by reducing the size of the vertical and horizontal members found from the viewpoint of openness and design.

  By the way, it is generally known that the load points of the glass plate applied to the horizontal member of the window frame are two points that are L / 4 apart from both ends of the lower side with respect to the length L of the lower side of the glass plate. It has been. Generally, a setting block having a predetermined support area is arranged at these two load points, and the weight (weight) of the glass plate is supported by a cross member through the setting block.

  On the other hand, in Patent Document 5, by placing both ends of the lower edge of the glass plate on the horizontal support portion of the self-weight receiving member that is cantilevered by the vertical member, and supporting the glass plate by the self-weight receiving member, A window plate-like support structure having no cross member is disclosed. A setting block having a support area smaller than the area of the horizontal support portion is generally disposed on the horizontal support portion of the self-weight receiving member, and the glass plate is supported by the self-weight receiving member via the setting block.

  The unit-type and knock-down type single window glass units are included in the category of the support structure of the window plate-like body of the present invention.

Japanese Patent Laid-Open No. 7-180246 JP 2006-152560 A JP 2005-155178 A Japanese Patent Laid-Open No. 2001-140390 JP 2005-264437 A

  However, as in Patent Documents 1 to 4 and the like, the conventional support structure for a window plate having a vertical member and a horizontal member has a smaller size of the vertical member and the horizontal member. As the size (area) of the plate-like body increases, the amount of bending of the vertical member and the cross member due to the weight (moment load) of the window plate-like member increases, so that it is difficult to slim the window frame. In particular, a support structure for a window plate that requires fire prevention and fire resistance is not desirable because the deformation of the cross member at high temperatures due to the weight of the window plate becomes significant.

  Further, the support structure of the window plate disclosed in Patent Document 5 has no cross member, and the self-weight receiving member is cantilevered by the vertical member. The moment load applied to the longitudinal member is larger than that of the longitudinal member provided with the transverse member. Therefore, when the left and right loads are unequal in the support structure disclosed in Patent Document 5, in order to increase the rigidity of the longitudinal member, the vertical dimension of the longitudinal member should be made larger than that of the support structure including the transverse member. Inevitably, the window frame cannot be slimmed.

  On the other hand, if the length of the horizontal support part of the weight receiving member is shortened in the support structure of Patent Document 5, the bending moment of the member due to the weight of the plate for the window is reduced, and the amount of bending of the vertical member is suppressed. Can do. However, as the length of the horizontal support portion of the self-weight receiving member is shortened, the size of the setting block disposed on the horizontal support portion is also reduced, and the contact area with the window plate is reduced. The stress (load point supporting stress) generated in the receiving member and the window plate increases. Therefore, when the support structure has a dynamic behavior such as at the time of an earthquake, the stress increases, and the stress is concentrated locally, so that the weight receiving member and the glass plate may be damaged. That is, since there is a limit to shortening the length of the horizontal support portion of the self-weight receiving member, there is a limit to suppressing the amount of bending of the vertical member.

  The present invention has been made in view of such circumstances. Even if the window plate has a large area, i.e., a large weight, the longitudinal member and It aims at providing the support structure body of the plate-shaped object for windows which can suppress the amount of bending of a cross member.

  In one aspect of the present invention, in order to achieve the above object, a window plate is formed by assembling a window frame in which a plurality of vertical members and a plurality of cross members are connected in a rectangular shape. In the plate-like support structure, a self-weight receiving member that supports the window plate-like body is disposed at a connecting portion between the vertical member and the cross member, and the vertical member and the cross member receive the self-weight receiver. Provided is a window plate-like support structure which is connected via a member.

  In one aspect of the present invention, it is preferable that the self-weight receiving member has higher rigidity than the cross member. High rigidity means that the elastic modulus such as Young's modulus is large.

  In one aspect of the present invention, the vertical member includes a first fitting portion, the cross member includes a second fitting portion, and the self-weight receiving member includes the first fitting portion of the vertical member. A third fitting part fitted to the second fitting part and a fourth fitting part fitted to the second fitting part of the transverse member, and connecting the longitudinal member and the transverse member. It is preferable that the vertical member and the cross member are fitted and connected by the member via the weight receiving member.

  As described above, according to the support structure for a window plate of the present invention, even if the window plate has a large area, that is, a large weight, the size of the vertical member and the cross member can be reduced. However, the amount of bending of the longitudinal member and the transverse member can be suppressed.

In the window glass unit 10 of the embodiment, the self-weight receiving member 18 that supports the multi-layer glass G is arranged at the connecting portion 20 between the vertical member 12 and the horizontal member 14 as shown in FIG. Are connected via a self-weight receiving member 18.

  That is, the window glass unit 10 according to the embodiment supports the self-weight of the multilayer glass G by the self-weight receiving member 18 arranged at the connecting portion 20 between the vertical member 12 and the cross member 14. Thereby, even if the vertical dimension of the vertical member 12 and the horizontal member 14 is reduced, the bending moment generated in the vertical member 12 and the horizontal member 14 due to the self-weight of the multilayer glass G can be kept small. Can be suppressed. That is, the window glass unit 10 includes the vertical member 12 and the horizontal member 14, but the weight of the multilayer glass G is reduced by the weight receiving member 18 at the intersection of the neutral shaft of the horizontal member 14 and the vertical member 12 or in the vicinity thereof. It is because it supports.

  Moreover, since the crosspiece 14 bears an axial force, the window glass unit 10 can suppress the deformation of the vertical piece 12. Therefore, compared with the support structure of Patent Document 5 that supports the weight of the window plate body only with the axial force of the vertical member, the cross-sectional rigidity required by the vertical member can be set lower. The finding dimension can be reduced.

  As described above, according to the window glass unit 10 of the embodiment, even if it is a multi-layer glass G having a large area, that is, a large weight, even if the vertical dimension of the longitudinal member 12 and the transverse member 14 is reduced, the longitudinal member. 12 and the amount of bending of the cross member 14 can be suppressed.

  Further, in applications where fire prevention / fire resistance performance is required, the window glass unit 10 according to the embodiment can suppress deformation of the cross member 14 at a high temperature due to the self weight of the multilayer glass G due to the presence of the self weight receiving member 18. Fireproof performance is improved.

  Further, since the window glass unit 10 includes the self-weight receiving member 18 on which a setting block having a necessary length can be arranged, there is a problem that the load point supporting stress increases which is a concern with the support structure of Patent Document 5. Can be eliminated.

  Furthermore, since the self-weight receiving member 18 is made of a material having higher rigidity than the cross member 14, the supporting force of the multilayer glass G can be improved.

  The window glass unit 10 according to the embodiment has a fitting structure in which the connection structure between the vertical member 12 and the self-weight receiving member 18 and the connection structure between the cross member 14 and the self-weight receiving member 18 are fitting structures. The shafts of the fitting portions 84 of the receiving member 18 can be aligned or brought close to each other, and the shafts of the cross members 14 and the fitting portions 86 of the own weight receiving member 18 are matched or brought close to each other. Is possible.

  Therefore, the moment load received by the vertical member 12, the horizontal member 14, and the own weight receiving member 18 can be minimized. That is, when the weight receiving member 18 is externally attached to the vertical member 12 and the horizontal member 14, or the internal weight receiving member 18 is attached internally, the respective axes cannot be aligned or brought close to each other. The received moment load cannot be reduced effectively. In addition, in the case of external attachment or internal attachment, the thickness of the weight receiving member is added to the finding of the vertical member and the transverse member, and the total finding is increased or the design for slimming is difficult.

  As mentioned above, although the window glass unit 10 was explained in full detail using drawing, this invention is not limited to the said embodiment, The various design change in the range which does not deviate from the summary of this invention is carried out. Etc. are possible.
