Description

[Detailed description of the invention] The invention relates to a curtain wall mounting structure, and more specifically, in installing a curtain wall, anchor bolts are planted in the front of the building frame.
This invention relates to a curtain wall mounting structure in which a surface-adjustable mounting bracket is fixed to the threaded portion of the anchor bolt, and a long horizontal frame member is mounted via the mounting bracket.

Traditionally, glass plates, panels,
As an installation structure for installing a curtain wall made of porcelain plates, etc., for example, a fastener or the like is attached to the front of the building frame, a long curtain wall frame material is fixed via this fastener, and then the curtain is attached using this frame material. A structure that supports and fixes a wall is known.

However, in this type of structure in which fasteners are directly fixed, it is difficult to position the fasteners and align the surface, and as a result, the outer surface of the curtain wall becomes wavy or distorted, which is not desirable for the exterior design of the building. Nakatsuta.

Moreover, it takes considerable time and effort to accurately install the fasteners, resulting in poor efficiency in the curtain wall installation process.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology, and allows for easy positioning and surface level adjustment of the mounting bracket, and allows the curtain wall to be easily and accurately supported and fixed to the front of the building frame. The purpose of this invention is to provide a curtain wall mounting structure that can be used.

In order to achieve this purpose, the present invention involves planting anchor bolts at predetermined positions on the front of the building frame.
A solid long horizontal frame member is fixed to the threaded part of this anchor bolt with at least two nuts via a mounting bracket and a joint material, and the curtain wall is supported and fixed by the joint material and the horizontal frame material. It is.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is an external view of a building according to this embodiment. In this building, a plurality of solid long horizontal frame members 2 are horizontally arranged in front of the building frame 1, and a curtain wall wall C is supported and fixed by a pair of horizontal frame members 2, 2. .

Figure 2 is a sectional view taken along line A-A in Figure 1; FIG. 3 is a sectional view taken along the line BB in FIG. 1.

In the figure, reference numeral 4 indicates anchor bolts, and a large number of anchor bolts 4 are installed on a predetermined horizontal line in front of the building frame, and a threaded portion 41 of each anchor bolt 4 protrudes above the surface of the frame 1.

The threaded portion 41 of each anchor bolt 4 has
A mounting bracket 5 for fixing the horizontal frame member 2 is attached via the joint member 3. As shown in FIG. 4, the basic shape of the mounting bracket 5 is to form a head 51 by bending a metal plate into a substantially U-shaped cross section, and a base 52 by bending both ends of this U-shape outward at approximately right angles. , 52 respectively, and further a head 51
The base portions 52, 52 have screw mounting holes 54, 54, respectively.

The mounting hole 53 is loosely fitted into the threaded portion 41 of the anchor bolt 4, and the head 51 is clamped at a predetermined surface position by at least two nuts 6 and 7 screwed into the threaded portion 41. .

Further, the joint material 3 is fixed to both base portions 52 of the mounting bracket by screws 8 inserted into screw mounting holes 54, 54, etc. This joint material 3 has a locking portion 31 approximately in the center thereof, and screw mounting holes 32, 32 are bored at both ends. Further, the horizontal frame member 2 is composed of a front plate 21 and a retaining piece 22 on the back side thereof, and the retaining piece 22 retains the retaining portion 31 of the joint material 3, and both of them engage the upper groove portion 32 and the lower portion. A groove portion 33 is formed.

Then, screws 8 are inserted into the screw attachment holes 34, 34 and the screw attachment holes 54, 54 of the mounting bracket 5.
is inserted and tightened, and the horizontal frame member 2 is fixed to the base portion 52 of the mounting bracket 5 via the joint member 3.
Here, if the screw mounting holes 54 or 34 are each made larger in diameter than the screw 8 or made vertically elongated, the vertical adjustment of the horizontal frame member 2 is possible within the range of the diameter of the screw mounting holes 54 and 34. It becomes possible.

In the upper groove portion 32 formed by the horizontal frame material 2 and the upper part of the joint material 3, an upper curtain wall is provided with a cushioning material 10.
The lower curtain wall C is placed in close contact with the sealing material 11, and the lower curtain wall C is tightly adhered with the sealing material 11 in the lower groove portion 33 formed by the lower part of the horizontal frame material 2 and the joint material 3 to perform rain protection treatment. It is well equipped.

In order to attach the curtain wall C to the front of the building frame 1, as shown in FIGS. 2 and 3, a large number of anchor bolts 4 are installed on a predetermined horizontal line on the surface of the building frame. Screw or insert the nuts 6, mounting brackets 5, and nuts 7 into the threaded portions 41 of each anchor bolt 4 in sequence, and operate the two nuts 6, 7 to secure the mounting brackets 5 at predetermined surface positions. wear it.

Next, the base portions 52, 5 of this mounting bracket 5
Screw mounting holes 54, 54 provided in 2 and screw holes 34, 34 of joint material 3 into which horizontal frame material 2 was fitted in advance
After adjusting the vertical direction of the horizontal frame member 2, the joint member 3 is fixed to the mounting bracket 5 with screws 8.

In addition, in order to readjust the vertical direction after this fixation, it is sufficient to loosen the screw 8 and move the joint material 3 up and down. After arranging horizontal frame members 2 in multiple stages horizontally in front of the building frame 1 in this way, a pair of upper and lower horizontal frame members 2
If you hold the upper and lower ends of curtain wall C with
The curtain wall C is supported and fixed to the front of the frame 1.

In this way, the curtain wall C is supported and fixed using the mounting bracket 5 which is clamped to the anchor bolt 4, the joint material 3 fixed to this mounting bracket 5, and the horizontal frame material 2. After adjusting the surface of the mounting bracket 5 using the nuts 6 and 7, vertical adjustment is made and the horizontal frame material 2 is attached to the joint material 3.
If it is fixed to the mounting bracket 5 via the horizontal frame member 2 and the joint member 3, the curtain wall C can be supported and fixed accurately and flush.

In the above embodiment, as already explained, the mounting bracket 5 is formed by bending a metal plate having a substantially U-shaped cross section and bending both ends of the metal plate outward at approximately right angles, but the present invention is not limited to this. In short, it is sufficient to have the mounting hole 53 and the mounting screw holes 54, 54, so the overall shape is made, for example, a simple rectangular shape, and the screw of the anchor bolt 4 is attached to the joint material 3 fixed to this. A recessed portion capable of accommodating the portion 41 may be provided.

In addition, the two nuts 6 and 7 in the above embodiment
If one of the nuts is fixed to the mounting bracket 5 in advance by welding or the like, there is an advantage that the surface level adjustment of the mounting bracket 5 can be performed more easily.

As explained above, in the present invention, the curtain wall is supported and fixed using a mounting bracket that is fastened to an anchor bolt with at least two nuts, and a joint material and a horizontal frame material that are fixed to this mounting bracket. As a result, you can easily adjust the surface of the horizontal frame material by operating two nuts, and by moving the joint material up and down relative to the mounting bracket, so-called level adjustment is also possible, making it possible to adjust the curtain wall. It can be easily and flush mounted on the side of the building structure.
