Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an improvement in a mounting structure of a curtain wall unit mounted so as to cover the outside of a wall surface.

<Prior Art> Conventionally, the curtain wall unit mounted so as to cover the exterior wall surface has been fixed to the wall surface, and it has been impossible to remove the curtain wall unit after the construction.

<Problems to be solved by the invention> Since the conventional curtain wall unit cannot be removed as described above, it is necessary to replace the curtain wall unit after construction, for example, when the curtain wall unit is damaged. The wall had to be destroyed, which was virtually impossible.

The present invention has been proposed to solve such a problem, and an object thereof is to obtain a curtain wall unit mounting structure that can be easily removed during maintenance from the outside after mounting the curtain wall unit. .

<Means for Solving the Problems> In order to solve the above problems, the curtain wall unit mounting structure according to the present invention is a curtain wall unit mounting structure mounted so as to cover the outside of a wall surface. The upper ridge for pressing the face plate is detachable from the outside, and the upper side of the curtain wall unit is supported from the inside by a bracket fixed to the wall to support the lower side of the upper curtain wall unit. The bracket is detachably fixed by at least two bolts penetrating the bracket, and the groove formed in the lower side of the upper curtain wall unit is fitted into the upper protruding portion of the lower side support bracket to support the upper curtain wall unit. , At least two of the lower support brackets A maintenance bolt screwing screw is provided in one of the holes through which the bolt penetrates.

<Operation> Since the curtain wall unit according to the present invention is configured as described above, when the removal is required for maintenance, the upper side that holds the surface plate of the curtain wall unit from the clearance between the units Of the at least two bolts that fix the upper side of the curtain wall unit from the inside after removing the ridge,
First, the bolt on the side provided with the screw is attached to the through hole, and then the maintenance bolt is screwed to hold the lower side support bracket to the curtain wall unit. In this state, by removing the remaining bolts, the upper side of the curtain wall unit becomes free with respect to the bracket fixed to the wall, and the lower side support bracket is rotated downward due to its eccentric moment around the maintenance bolt. Retained. Then, by removing the bolts that secure the upper side of the curtain wall unit below it in the same way as above, the lower side support bracket rotates downward and comes out of the groove on the lower side of the upper curtain wall unit. Also, the lower side of the curtain wall unit will be free, and the upper and lower fixed parts will be removed, allowing for removal.

Further, the mounting after maintenance can be performed in the reverse order of the above.

<Embodiment> An embodiment of the present invention will be described below with reference to FIGS.

In the figure, reference numeral 20 is one curtain wall unit, which is mounted as an exterior of the wall surface at four positions in the vertical and horizontal directions as will be described below while maintaining a clearance 4 with the surrounding curtain wall unit 20 as shown in FIG.

Reference numeral 1 is a surface plate of the curtain wall unit 20, 2 is an upper side ridge for pressing the surface plate 1, 3 is a set screw for stopping the upper side ridge, and the upper side ridge 2 is removed by removing the set screw 3 from an external clearance 4. You can do it. Reference numeral 5 is the inside of the upper ridge 2, 6 is the upper side of the curtain wall unit 20, 7 is a bolt for mounting the curtain wall unit, 8 is a lower side support bracket of the upper curtain wall unit, and 9 is a bracket fixed to the wall surface. . The upper side portion 6 of the curtain wall unit 20 sandwiches the lower side support bracket 8 with, for example, two bolts 7 inserted from the inside 5 of the upper side ridge 2, and is detachably fixed to the upper left and right two places of the bracket 9.

The lower side support bracket 8 is provided with an upper protruding portion 11,
A groove 12 formed by fixing a bracket 13 to a lower side portion 10 of an upper curtain wall unit 20 is fitted to the protruding portion 11, and a left and right side through which two bolts 7 penetrate. A pair of bolt through holes 14 are bored, and the through holes 14 are larger than the bolt diameter.
One is provided with a screw 16 for screwing a maintenance bolt 15 larger than the bolt 7 by about 2 mm. In addition, 17 is a zircon member.

In the above embodiment, the curtain wall unit 20
When it becomes necessary to replace it due to damage to the wrench, first remove the setscrew 3 that holds the upper ridge 2 in place, and then, of the two bolts 7 inserted from the inside 5, the maintenance bolt 15 The bolt 7 on the side of the through hole 14 provided with the screw 16 of the lower side support bracket 8 is removed, and then the maintenance bolt 15 is inserted and screwed into the screw 16 of the through hole 14 of the lower side support bracket 8. The lower side support bracket 8 is held on the curtain wall unit 20 side. In this state,
By removing the other bolt 7, the lower side support bracket 8 is rotated downward about the maintenance bolt 15 as shown in FIG.
And the upper side 6 of the curtain wall unit 20 is detached from the bracket 9 fixed to the wall surface and becomes free.

Next, in the curtain wall unit 20 located below the curtain wall unit 20 to be removed,
By removing the bolt 7 that fixes the upper side portion 6 in the same manner as described above, the lower side support bracket 8 is moved to the second side.
As shown in the drawing, the protrusion 11 is disengaged from the groove 12 of the upper curtain wall unit 20 by rotating downward. As a result, the lower side portion 10 of the curtain wall unit 20 to be removed is also in a free state. Therefore, the curtain wall unit 20 can be detached by using the structure in which the vertical portions are not crossed, and the maintenance becomes possible.

After the maintenance, when the curtain wall unit is fitted, the lower side support bracket 8 is rotated upward at the four positions of the upper, lower, left, and right by rotating the maintenance bolts 15 and fitted into the groove 12 in the reverse order to the above. The curtain wall unit 20 can be mounted by tightening the bolt 7 in this state, further removing the maintenance bolt 15, and then tightening the bolt 7.

Therefore, the attachment / detachment of the curtain wall unit 20, which has been substantially impossible in the past, can be easily performed from the outside.

<Effects of the Invention> As described above, according to the curtain wall unit mounting structure of the present invention, it is possible to easily attach and detach from the outside even after construction, and therefore, in case of damage,
Maintenance such as replacement and repair can be performed easily.

In addition, since it is possible to prevent the lower side support bracket from falling off during attachment and detachment, it is possible to ensure safety and improve workability.
