[Industrial applications]

 The present invention relates to a horizontal member cover for a tilted curtain wall in which a wall surface covers a horizontal member of a curtain wall which is inclined with respect to a vertical plane.

[0002]

[Problems to be Solved by Prior Art and Invention]

 The unit type curtain wall is connected to a vertical member such as a cubic member that supports the unit, and the horizontal member, such as a seamless member, is installed above and below the unit. A cover to cover the whole is installed, but this cover is usually placed on the inside of the horizontal material to avoid exposing the screws due to fixing the screws, as in the case of No. 56-76816 and No. 59-24829. It is detachably attached by engaging the engaging pieces at the tips of the upper and lower pieces in a snap manner with the protruding receiving piece.

However, in this snap-type mounting structure, the cover and the receiving piece are not easily manufactured because they are detachable, and in addition, thermal expansion of the vertical member, vibration due to an earthquake, etc. If it comes off, it may fall, especially if the wall surface is inclined with respect to the vertical plane.

The present invention has been made in view of the problem of this conventional cover mounting method, and is intended to newly propose a cover that prevents falling.

[0005]

[Means for Solving the Problems]

 In the present invention, the position of the engaging piece of the upper cover piece that supports the load of the horizontal material cover itself is located closer to the horizontal material side than the center of gravity of the cross-section of the horizontal material cover, so that the engaging piece is always supported on the horizontal material cover. As a result, a moment that the center of gravity moves toward the cross member is applied to stabilize the movement and prevent it from falling.

The horizontal material cover is an indoor piece having a width corresponding to the found width of the horizontal material, and an upper receiving piece that extends horizontally from the upper and lower ends to the horizontal material side and projects from the upper and lower ends of the horizontal material to the indoor side. The upper cover piece and the lower cover piece each have an engaging piece that engages with the lower cover piece, and the upper cover piece and the lower cover piece each have a U-shaped cross-sectional shape. To be done.

The crosspiece cover is supported on the crosspiece by the engaging piece of the upper cover piece, and is located on the crosspiece side with respect to the center of gravity of the cross section in the vertical cross section, so that the crosspiece cover corresponds to the eccentric amount. The lower cover piece receives a moment when it tries to rotate toward the horizontal member, and has a resistance to disengagement when attached to the horizontal member.Even if the engaging piece of the lower cover piece disengages from the lower receiving piece, it will return to its original position. Attempt to return to, and fall is prevented.

【Example】

 The present invention will be described below with reference to the drawings showing an embodiment.

As shown in FIG. 1, the horizontal member cover C of the present invention is a curtain wall inclined with respect to the vertical plane, and is provided on the upper and lower ends of the horizontal member F installed between the vertical members M to project indoors. The upper receiving piece f ₁ and the lower receiving piece f ₂ are elastically engaged with each other and attached to the cross member F to cover the cross member F.

The horizontal member cover C has an indoor piece C3 having a width corresponding to the found width of the horizontal member F, and the upper and lower ends thereof horizontally project to the upper receiving piece f ₁ and the lower receiving piece f ₂ side of the horizontal material F, the cross-sectional shape of the U-shaped from each upper cover piece C1 bottom casing piece C2 Metropolitan with engaging pieces 1 and 2 to engage the upper receiving piece f ₁ and the lower receiving piece f _2, engagement of the upper cover piece C2 The piece 1 is supported by the cross member F, and the upper and lower engaging pieces 1 and 2 are attached to the upper receiving piece f ₁ and the lower receiving piece f ₂ by snapping engagement.

Since the horizontal member cover C also covers the bracket B connecting the horizontal member F to the vertical member M, the widths of the upper cover piece C1 and the lower cover piece C2 are large enough to accommodate the bracket B and the bolt b. ing.

As shown in the drawing, the engagement piece 1 of the upper cover piece C1 is located closer to the horizontal material F than the center of gravity G of the cross-section of the horizontal material cover C, and the horizontal material cover C is of the lower cover piece C2. It is attached to the cross member F in a state where the tip always receives the force of contacting the cross member F.

That is, the cross member cover C is supported on the cross member F by the engagement piece 1 of the upper covering piece C1, and the cross piece F is located closer to the cross member F than the center of gravity G of the cross section, so that According to the eccentricity between the engagement piece 1 and the center of gravity G, that is, the horizontal distance, the cover C uses the engagement piece 1 as a fulcrum to move the lower cover piece C2 toward the cross member F side, in the clockwise direction shown by the arrow in the drawing. This moment causes the crosspiece cover C to be kept in a state in which the lower cover piece C2 abuts the crosspiece F by this moment.

In normal times, among the engaging pieces 1 and 2 of the upper covering piece C1 and the lower covering piece C2 which are engaged with the upper receiving piece f ₁ and the lower receiving piece f ₂ , due to a cause such as thermal expansion or vibration. If the engagement is disengaged, the engagement piece 2 of the lower cover piece C2 to which no load is applied is likely to be released in advance, so that the cross member cover C is formed by the engagement piece 1 as shown by the chain line in FIG. Although it is in a suspended state in which it is supported, in this case, the cross member cover C easily returns to its original position due to the reason described above.

[0015]

[Effect of the device]

 The present invention is as described above. Since the position of the engaging piece of the upper cover piece that supports the load of the cross member cover itself is located on the cross member side from the center of gravity of the cross section, The material cover is always attached to the horizontal material while the center of gravity receives the moment that the center of gravity moves toward the horizontal material with the engaging piece of the upper cover piece as the fulcrum. Is sure to prevent falling.
