Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a device for joining mullions and blinds, such as curtain walls.

(Prior art) Generally, when a curtain wall is integrally attached to a structural frame, the curtain wall cannot follow the deformation of the structural frame because the deformation abilities of the curtain wall and the structural frame are different, and the glass and panels of the curtain wall are It may be damaged or deformed.

For this reason, curtain walls are installed so that they can rock or horizontally follow the deformation of the structural frame due to earthquakes, etc., in order to prevent the glass and panels of the curtain wall from being damaged or deformed due to deformation of the structural frame.

In addition, in the mullion curtain wall,
For the same reason, the mullion and the mullion are not integrally connected, but are installed so that the mullion can be moved horizontally by a certain amount in the left and right direction.

Traditionally, Jikosho was used as a method of connecting mullions with no eyes.
There is one disclosed in Publication No. 58-7846.

This type of connection method involves installing a bracket horizontally on the side of the mullion, forming a long hole in the open end, placing the open end on top of the bracket, and fixing it on top of the open end. The mullion and the mullion are connected by placing a block thereon and screwing the fixing block and the bracket together with the mounting screws passing through the elongated holes.

(Problem to be solved by the invention) However, in this connection method, the blind ends are directly and strongly sandwiched between the bracket and the fixed block and are connected in a mullion. There were cases where it was not possible to move horizontally without eyes smoothly. Additionally, over the years, the mounting screws themselves loosened, causing the connecting parts to wobble. As a result, the sealing material installed to prevent rainwater from entering may become dislocated, resulting in a loss of watertightness.
Airtightness was sometimes impaired.

This invention was proposed in order to solve the above-mentioned conventional problems, and it can smoothly follow the deformation of the structural frame and prevent loosening of the mounting screws.
It is an object of the present invention to provide a joining device for a mullion and a blind, which can completely prevent the rattling of the connecting portion and the displacement of the sealing material caused by this.

(Means for solving the problem) This invention relates to a device for joining a mullion and a mullion, in which a bracket insertion hole 3 is provided horizontally at the junction of the mullion 1 and the mullion 2. Insert the bracket 5 into the bracket insertion hole 3 with both ends protruding to both sides of the mullion 1, and place the left and right blinds 2,
A spacer 11 is placed between the connecting parts 18, 18 of 2, and a notch 19 is formed to be elongated in the longitudinal direction of the closed part 2 at approximately the center of the connecting parts 18, 18. 18 and spacer 1
The fixing blocks 12, 12 are placed on top of the fixing block 1, and the fixing blocks 12, 12, the spacer 11, and the bracket 5 are screwed together.
7 is formed, and the connecting portions 18, 18 are connected to the spacing portion 17.
It is characterized by being formed to a thickness that allows it to be inserted into.

(Example) Hereinafter, this invention will be explained using an example illustrating the invention.
Between 1 and 1, blinds 2, 2 are installed at regular intervals in the vertical direction of the mullion 1.

The mullion 1 is formed with an H-shaped cross section.
A circular bracket insertion hole 3 and a circular pin insertion hole 4 located below the bracket insertion hole 3 are formed in the seamless connecting portion.

The bracket insertion hole 3 and the pin insertion hole 4 are continuous.

A bracket 5 is inserted into the bracket insertion hole 3 in a state that it projects horizontally from both sides of the bracket insertion hole 3.

The bracket 5 has a substantially comb-shaped cross section. The lower side of the bracket 5 has a bracket insertion hole 3.
It is formed into a curved surface with a curvature that is one size larger than the inner circumference.

A groove 6 is formed continuously in the circumferential direction of the bracket 5 at approximately the center of the lower side of the bracket 5, and the lower edge of the bracket insertion hole 3 is fitted into the groove 6. Pin insertion hole 4 on the side
A groove 7 having the same curvature is formed over a certain range from one end of the bracket 5 toward the other end, and one fixing pin 8 is inserted across both the groove 7 and the pin insertion hole 4.

As a result, the bracket 5 is firmly fixed in the bracket insertion hole 3 without tilting or rotating.

Further, the upper end of the bracket 5 is formed into a horizontal flat shape. Further, a plurality of screw holes 9 and 10 are formed at the upper end of the bracket 5 at regular intervals in the longitudinal direction with the center thereof as a boundary.

Furthermore, a spacer 11 having a substantially rectangular parallelepiped shape is placed on the center of the bracket 5, and fixing blocks 12, 12 are placed on top of this spacer 11.

The fixing block 12 has a generally comb-shaped cross section like the bracket 5, and is approximately half the length of the bracket 5.

Further, the upper side of the fixing block 12 is formed into a curved surface having a curvature one size larger than the inner circumference of the bracket insertion hole 3. A plurality of through holes 13 and 14 are formed in the center of the fixing block 12, corresponding to the screw holes 9 and 10 of the bracket 5.

Further, a curved stepped portion 15 having the same curvature as the inner periphery of the bracket insertion hole 3 is formed continuously in the circumferential direction of the fixing block 12 at the tip end of the fixing block 12, 12.

The stepped portion 15 is fitted into the bracket insertion hole 3.

The fixing blocks 12, 12, the spacer 11, and the bracket 5 are integrally connected by screwing connection screws 16, 16 into the screw holes 9 of the bracket 5 through the through holes 13, 13 of the fixing block 12. .

With this configuration, space portions 17, 17 having a constant width are formed between the bracket 5 and the fixed blocks 12, 12.

At both left and right ends of the blind 2, there are plate-shaped connecting parts 18,
18 are formed. The connecting portion 18 is formed to have a thickness that allows it to be inserted into the space 17 between the bracket 5 and the fixing block 12.

Further, a notch 19 is provided approximately at the center of the connecting portion 18.
is formed to be elongated in the longitudinal direction of the mesh 2.

Then, the connecting part 18 is inserted into the spacer part 17 and the through hole 14 of the fixing block 15 is inserted into the hole 2.
The connection screw 20 is connected to the mullion 1 by screwing into the screw hole 14 with the connection screw 20 passing through the notch 19.

In such a configuration, the connection part 18 of the two blind ends is not clamped in the gap 17 between the bracket 5 and the fixing block 15, but is simply inserted into the gap 17, and the connection screw 20 It's just to prevent it from shifting laterally, so it's Mume 2.
can move horizontally from side to side.

Therefore, the connecting portion between the mullion 1 and the mullion 2 can freely follow the deformation of the structural frame due to earthquakes and the like.

(Effects of the invention) Since this invention consists of the above configuration, it has the following effects.

The joints at both ends of the bracket are not firmly clamped between the bracket and the fixing block, but are simply inserted into the gap formed between the bracket and the fixture block. Since it has a notch, it can move freely laterally and follow the deformation of the structural frame due to earthquakes, etc. Therefore, loosening of the mounting screws between the mullion and the mullion, accompanying looseness of the connecting parts, and misalignment of the sealant,
Cutting can be completely prevented.
