Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to an angular cubic curtain wall in which face plates connected on the left and right sides are attached at an angle of either an out or an inlet corner.

(Prior art) Conventionally, as shown in Fig. 7, as an indoor partition,
Vertical frame material f for supporting the surface plate having an arcuate joint surface on the side surface
and a connecting member g having arc-shaped joint surfaces on both sides, and the arc-shaped joint surfaces of the vertical frame members are rotated along the arc-shaped joint surfaces of the vertical frame members, respectively. It is known that the left and right adjacent face plates are connected at a desired angle by fixing them with bolts h at desired rotational positions, and then supporting the face plates i on each vertical frame member. However, this conventional arc-shaped joint surface structure has many problems such as strength issues when used as is in a mullion-type curtain wall, and improvements in these points have been desired.

(Problems to be Solved by the Invention) The object of the present invention is to provide a cubic curtain wall in which adjacent face plates can be connected at any angle.

(Means for solving the problem) In order to achieve the above purpose, this proposal consists of a plurality of mullions fixed to the building frame at a horizontal distance from each other, and a plurality of mullions attached to both the left and right sides of the mullions. The attached vertical frame members, the plurality of horizontal frame members installed between the vertical frame members of the adjacent mullions, and the surface plate supported within the frame formed by the vertical frame members and the horizontal frame members. The above-mentioned mullion has a cylindrical main part at the outdoor end of the base, which is fixed at one end to the building frame and the other end projects to the outdoor side, and left and right sub parts on both left and right sides of the base. The outer circumferential surface of the cylindrical main part is formed as an outer arcuate joint surface, and the outdoor side surfaces of the left and right sub-parts are formed as inner arcuate joint surfaces concentric with the outer arcuate joint surface, thereby forming an inner and outer diagonal opening laterally. A heavy arc-shaped joint surface is formed on both the left and right sides of the mullion, and the vertical frame material has a surface plate support portion on one side,
The other side has inner and outer arcuate joint surfaces in a concentric relationship with each other corresponding to the inner and outer arcuate joint surfaces of the mullion, and the inner and outer arcuate joint surfaces are connected to the inner and outer arcuate joint surfaces of the mullion. It has a structure in which it is rotatably joined to the arcuate joint surface and both joint parts are fixed at a joining position at a desired angle. Embodiments of the present invention will be described below with reference to the drawings.

The mullion 1 has its plate-like base 5 connected to the structural material F.
Fasteners 8 fixed to the outdoor end of the base 5 are fixed vertically with bolts 9, 9 and nuts 10, 10 with the base plate surface facing the indoor/outdoor direction. 5 As shown in the figure, a hollow cylindrical main part 6 is integrally formed, and on the left and right side surfaces of the intermediate part of the base 5, sub parts 7, which are groove-shaped pieces in this example, are formed.
7 are fixed in a wing shape with bolts 11 and nuts 12 in appropriate numbers, the outer peripheral surface of the cylindrical main part 6 is the outer arc-shaped joint surface b, and the outdoor side surfaces of the secondary parts 7, 7 are the outer arc-shaped The inner arcuate joint surfaces a, a are formed in a concentric relationship with the joint surface b, thereby forming mullion 1.
On both the left and right sides, there are formed inner and outer double joint surfaces that are open to the sides and are made up of inner and outer arcuate joint surfaces a and b.

As shown in the sixth figure, the vertical frame member 2 has a raised edge 13 added to one side thereof to form a fitting groove 14 as a surface plate support portion, and the other side has an inner and outer arc-shaped joint of the mullion 1. An inner arcuate joint surface a' and an outer arcuate joint surface b' are formed in a concentric relationship with each other corresponding to surfaces a and b, and the inner and outer arcuate joint surfaces of the vertical frame member 2
a' and b' are inserted into the inner and outer arcuate joint surfaces a and b of the mullion from the sides and are rotatably joined, and each joint part is fixed with screws 15...16 at the joint position at a predetermined angle. . Note that the vertical frames 2, 2 attached to both left and right sides of the mullion 1 have symmetrical cross-sectional shapes. 2a is a recess provided at the outdoor end of the outer arcuate joint surface b', and a sealing material 2b is filled between the recess 2a and the mullion main part 6 to ensure watertightness between the mullion 1 and the vertical frame member 2. I'm keeping it.

As shown in the fourth figure, the horizontal frame member 3 has fitting grooves 17 and 18 formed on the upper and lower surfaces as surface plate supports, and both left and right ends of the horizontal frame member 3 are connected to the adjacent mullions 1 and 1. It is supported by brackets 19, 19 attached to the sides of the vertical frame members 2, 2.

Fitting grooves 14 around the four circumferences of each frame formed by the vertical frame members 2... and the horizontal frame members 3... attached as described above,
14, 17, 17 or 18, 18 are fitted with the four circumferential parts of the surface plate 4, respectively.

The indoor end of the mullion 1 and the H-shaped structural member F portion exposed indoors of the indoor structure of the mullion 1 are covered with a cover 20, and the cover 20 has a cross section as shown in the third figure. Half of the cover bent into an almost U-shape 2
1 and 21 facing each other in a box shape, one end of which is fixed by screws 23 to a groove plate 22 located within the box shape, and this cover 20 is placed on the outside of the structural material F, With the groove plate 22 fitted onto the indoor flange of the H-shaped structural member F, the cover half 21,
21 are fixed to the protruding ends of the left and right sub-portions 7, 7 of the mullion 1 by screws 24.

In the present invention, the left and right sub-portions 7, 7 of the mullion 1 are not limited to the piece materials in the above example, but may be continuous materials extending over the entire length of the mullion, or may be integral with the mullion.

(Effect of the invention) According to the curtain wall of the present invention, the inner and outer arcuate joint surfaces of the vertical frame material are rotatably joined to the inner and outer arcuate joint surfaces of the mullion, and fixed at the joint position at a desired angle. Therefore, adjacent surface plates can be connected to each other at arbitrary angles such as out or in corners, and moreover, the arcuate joint surfaces of the inner and outer double of the mullion and the inner and outer double of the vertical frame material can be connected to each other at arbitrary angles. In addition to making a strong double joint connection with the arcuate joint surface, the mullion itself has high strength due to its cylindrical main part that also serves as the outer arcuate joint surface, and this together with the necessary stiffness as a curtain wall. It is possible to provide watertightness, and during construction, the mullions are installed in the same way as conventional mullion-type curtain walls, and when joining the vertical frame materials to the mullions, the mullions are Since the inner and outer double arcuate joint surfaces of the vertical frame member can be inserted while rotating through the side openings of the inner and outer double arcuate joint surfaces, the work can be carried out more efficiently.
