Description CURTAIN WALL FASTENING APPARATUS FOR ADJUSTING LEVEL [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a curtain wall fixing device capable of adjusting a level, and more particularly, to a curtain wall fixing device capable of adjusting a level of a curtain wall through a conventional manual operation, The present invention relates to a curtain wall fixing device capable of finely adjusting the upper and lower levels of a curtain wall.

Generally, the building consists of columns and beams, which are the main structure, and consists of structures supporting the vertical and horizontal loads applied to the building. In this case, the wall simply acts as a partition, and this wall is called a curtain wall.

Curtain walls are mainly used in high-rise building structures, where curtain wall units assembled at the factory are installed in the building frame, precisely at this time. For such a precise combination, it is very important to adjust the height of the curtain wall in general, and the height adjustment of the curtain wall is largely determined by the operator's personal skill. However, various devices have been attempted to easily adjust the elevation level of the curtain wall so as not to depend heavily on the skill of such operator.

Figures 1 and 2 are exploded perspective views of a conventional fastening device for attaching a curtain wall to a slab. Referring to FIG. 1, slabs (bricks, buildings, etc., which are horizontal plate-like parts, for example, floor, ceiling and the like, The bracket 10 is provided with a vertically long opening so that the height of the bracket 20 attached to the curtain wall 2 can be adjusted through the opening to tighten the bolt .

However, when the weight of the curtain wall 2 is excessively large, there is a problem that it is very difficult for an apparatus of the type shown in FIG. 1 to lift the curtain wall 2 directly by a worker and proceed with the work. Also, there is a problem that the range in which the level of the curtain wall 2 can be adjusted is limited only to the length of the vertical opening formed in the bracket 10, and in the case of a large error range, As the length becomes relatively longer, there is a problem that it interferes with the flooring material, resulting in a problem that it can not be applied when the flooring material is low.

2, the bracket 10 is firmly attached to the slab 1, the intermediate bracket 40 is fastened to the bracket 10, and the bracket 10 is fastened to the curtain wall 2 It is common to adjust the height of the curtain wall 2 by connecting the brackets 20 connected to the brackets 20 and adjusting the bolts 21 connected to the brackets 20. [

2 can fine-tune the upper and lower levels of the curtain wall 2 but the bolt 21 receives the vertical load of the curtain wall 2 and applies pressure to the upper portion of the middle bracket 40, A severe compressive force is generated at the end portion of the flange 21, which causes horizontal buckling, which makes it difficult to move through the thread, that is, the level adjustment becomes impossible.

In order to move up and down with the bolts 21 engaged, there has been a problem that a nut has to be formed on the bracket 20. In this case, various platings, particularly, brackets are formed on the bracket 20 by steel The thread of the nut does not play a role in galvanizing.

Also, in the case of FIG. 2, the bolts 21 for adjusting the level are located at the upper part in the same manner as in FIG.

A device for adjusting the level of a curtain wall by using a bolt is a device for installing a curtain wall having a level bolt (Publication No. 10-2011-0120062; hereinafter referred to as a cited invention). 2, the level bolt directly presses the upper end of the vertical surface. When the level of the curtain wall is adjusted in this manner, the weight of the curtain wall is excessively increased, If the strength of the top and bolt is weak, these elements are easily trapped and have a fundamental problem that the level can not be adjusted.

The curtain wall fixing device capable of adjusting the level according to the present invention is devised to solve the above-described problems, and has the following problems.

First, it is intended to provide a curtain wall fixing device capable of adjusting the height of a curtain wall by tightening or loosening a bolt.

Second, when the bolt is tightened or loosened, the end of the bolt does not press the other part, and the level of the curtain wall can be adjusted using the bolt tightening force or the loosening force itself.

Third, it is intended to provide a device for preventing the various brackets and parts from being damaged even with frequent use of the bolts by allowing the operator to easily adjust the level of the curtain wall by fastening the bolts.

The solution of the present invention is not limited to those mentioned above, and other solutions not mentioned can be clearly understood by those skilled in the art from the following description.
