Description

[Detailed Description of the Invention] The present invention relates to a device for firmly attaching shapes such as curtain wall mullions, handrail supports, door jambs, etc. to building frames or walls using brackets.

Here, the installation of mullions on a curtain wall will be described as an example. The curtain wall mullions are attached to the building frame using brackets. This bracket is attached to the mullion and the building frame using bolts and nuts, and the nut portion is welded to prevent loosening. For this reason, installing the mullions was complicated and the work could not be carried out efficiently.

It is therefore an object of the present invention to provide a means by which a bracket can be easily connected to a shape such as a mullion in a steady state.

Based on the above object, the present invention forms a pair of grooves on the side surface of the profile using protrusions, fits the steady rest part of the bracket into these grooves, and combines the two without rattling. The mullion is indirectly attached to the building frame through the

Hereinafter, the present invention will be specifically explained based on embodiments shown in the drawings.

The profile attachment device 1 of the present invention is shown in FIGS. 1 and 2.
As shown in the figure, the main parts are composed of a mullion 2 and a bracket 3. Mullion 2 is
It is comprised of a hollow part 4 on the outdoor side and a window frame mounting part 5 integrally formed on the indoor side of this hollow part 4. The window frame mounting portion 5 also serves as a bracket mounting surface, and a pair of grooves 6 and 7 are formed on one side of the window frame mounting portion 5 to face each other on the left and right sides. These grooves 6, 7 are hook-shaped protrusions 8, which are integrally formed with the window frame mounting portion 5,
9. The steady rest portion 10 of the plate-shaped bracket 3 is inserted between the grooves 6 and 7. This bracket 3 is L when viewed from the side.
An upward steady rest part 10 is formed at the tip of the horizontally extending part 3a. The width of the steady rest portion 10 is set to be approximately equal to the distance between the bottom surfaces of the pair of grooves 6 and 7. A notch 11 is formed in a part of the protrusion 9 on the indoor side. The length of this notch 11 in the vertical direction is slightly larger than the overall height of the bracket 3. The proximal end of the protruding portion 3a of the bracket 3 is bent in an L-shape to form a mounting plate 12, and an L-shaped reinforcing mounting plate 13 is attached to the other surface by welding or other means. attached by means. These two mounting plates 12 and 13 have two elongated holes 14 in the vertical direction.
It is equipped with

On the other hand, an L-shaped connecting member 16 is attached to the building frame 15.
is attached with bolts and nuts 17.
The mounting position of the connecting member 16, that is, the amount of the connecting member 16 being brought out to the outdoor side, can be adjusted using the elongated hole 18. The connecting member 16 also has a horizontal elongated hole 19 in a portion facing the mounting plates 12 and 13 of the bracket 3, and this elongated hole 19 and the bracket 3
The bracket 3 and the connecting member 16 are brought into a connected state by the bolt/nut 20 inserted into the elongated hole 14.

Now, to install the mullion 2, first insert the steady rest part 10 of the bracket 3 from the notch 11, move the bracket 3 upward, and insert the protruding part 3a into the lower end of the protrusion 9, that is, the notch. 11, and the steady rest part 10 is connected to the pair of grooves 6,
Insert it between 7. At this time, since the steady rest part 10 fits between the pair of grooves 6 and 7, the bracket 3 is in a state where it does not wobble. If necessary, this bracket 3 can be made more secure by inserting fixing screws 22 into the upper and lower fixing holes 21 that have been drilled in advance, and screwing these fixing screws 22 into the window frame mounting part 5. Can be fixed. The mounting portions 12 and 13 of the bracket 3 are mounted to the connecting plate 16 through bolts and nuts 20 and elongated holes 14 and 19 so as to be adjustable in position. In this state, bracket 3 is
The mullion 2 is indirectly attached to the frame 15 while being brought out a certain distance from the frame 15 to the outdoor side.
The weight of the mullion 2 is supported by the contact between the lower end surface of the notch 11 on the indoor side and the upper end surface of the protruding portion 3a of the bracket 3.

A plurality of the mullions 2 are connected in a continuous manner in the vertical direction, and each is held by one bracket 3, but the mullion 2 located at the lowest end has a total of 2 in the upper and lower positions. It is held by two brackets 3. If the lower bracket 3 of these two brackets 3 comes into contact with the lower edge of the notch 11, there is a problem that the elongation due to thermal expansion of the mullions 2 cannot be released. Therefore, the bracket 3 in the lower position is provided with a space between its protruding portion 3a and the lower edge of the notch 11 to allow the elongation to escape, so that there is no direct abutment relationship.

A window frame 23 is attached to the window frame attaching portion 5 of the mullion 2, and a plate glass 25 is supported by the window frame 23 through a gasket 24. In addition, a cover material 26 is attached to the upper surface of the hollow part 4 with mounting fittings 35 and mounting screws 3.
6 is attached to the window frame 23, and a connecting plate 27 is attached to the upper surface of this cover material 26 and the window frame 23.
insert the mounting screw 28 into the tatsu pin hole 2 of the hollow part 4.
It is installed by screwing into 9. Also, on the upper surface of this connecting plate 27, there is a parapet 3 having a U-shaped cross section.
0 is attached by mutual engagement with it facing downward. Concrete slab 31 on top of frame 15
is formed, and a waterproof layer 32, a waterproof mortar 33, and a sealing material 34 are sequentially provided on the upper surface thereof.

Now, in the above embodiment, the pair of grooves 6, 7 are formed by a pair of protrusions 8, 9, but the grooves 6, 7 are formed on the side surface of the window frame mounting part 5, as shown in FIG. It can also be formed by a cylindrical protrusion 9 formed in a cylindrical shape. Moreover, the notch 11 is a groove 9 on the indoor side, as shown in FIG.
It may be formed not only in the portion but also in the groove 8 on the outdoor side. Further, the steady rest part 10 is constructed separately from the bracket 3, as shown in FIG.
It may be integrated with In this case two protrusions 8, 9
The lower end surfaces of both are the protruding portion 3a of the bracket 3.
This is advantageous because the load is distributed because it hits the upper end surface of the .

Note that the present invention is naturally applicable not only to the mullion 2 but also to shapes such as the above-mentioned handrail supports, door jambs, and other similar shapes.

According to the present invention, since the steady rest part of the bracket fits in the pair of grooves of the profile member in a steady rest state, the connection between the profile member and the bracket is reliable, and the protrusion forming the groove is Since the weight of the profile is supported by the top surface of the bracket, no mounting screws or the like are particularly required for load support. Therefore, the present invention simplifies the installation of the profile and the bracket, and allows the installation of the profile to be carried out efficiently.
