[0001] Frame Apparatus for construction [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a frame fixing device for a structure, and more particularly to a frame fixing device for a structure, more specifically, when a plurality of frames constituting a structure are connected by brackets and fastened with bolts, the bolts are released from the brackets by vibration of the air conditioning device In order to solve the conventional problem, the knob fixed to the horizontal frame and the sliding movement of the lock bundle have been improved to a bolt style in which the lock bundle is firmly fixed inside the lock projection of the lock plate fixed to the vertical frame, To a frame fixing device for a structure.

Generally, a frame of a structure is assembled by using a plurality of elongated frames, which are aluminum extruded shape members, and a door, a window, and the like are installed on a basic frame, and a blower and an air filtering device of an air conditioner are installed on a side wall of the frame .

Among these structures, high-precision equipment is installed in a semiconductor manufacturing room such as an electronic device, a laboratory, and a computer room in a clean room, and in the case of basic frames constituting a clean room, The horizontal frame member 34 is coupled to the side of the vertical frame member 28 such as the ash and the structure and the bracket 42 And the bolts 44 are fastened to the inside of the bracket 42 to fix the vertical frame material 28 and the horizontal frame material 34. In the case of the conventional bolt 44, The vertical frames 28 and the horizontal frame members 34 are firmly fixed to each other while the bolts 44 are released from the brackets 42 due to the vibration of the basic frames due to the operation of the air conditioner Problems of Non-Performing Construction .

7, when a bolt is fastened using a bracket as shown in FIG. 7, a minute gap is formed between the vertical frame member 28 and the horizontal frame member 34, so that dust and various foreign substances There is a problem in that micro-dust industry or micro-organism such as ultra-high-density integrated circuit or gene manipulation, which interferes with minute genes in cells, causes damage to equipment or products due to inflow of fine dust or bacteria.

Furthermore, in the case of the miniature industry, most of the air filtering apparatus is installed inside the clean room in order to prevent fine dust or germs from being inflowed into the clean room. In such an air filtering apparatus, There is a problem that it is released.

Many techniques have been developed for fastening the frames constituting these structures with bolts. However, in reality, products for preventing bolt loosening are expensive, and the bolts are adjusted from time to time according to working conditions. There is an urgent need for a product that can eliminate the hassle.

The frame failure device for a structure according to the present invention constructed as above operates as follows.

In the case of a structure formed by combining a longitudinal frame 11 and a horizontal frame 12 made of a long frame such as an aluminum extruded shape member, various structures such as a clean room are used. Among them, in the case of a clean room, The vertical frame 11 and the horizontal frame 12 must be firmly fixed so that the vertical frame 11 and the horizontal frame 12 are prevented from flowing into the interior of the clean room. In the conventional fastening method, since the bolts are used, And the maintenance work of the clean room must be carried out at any time since the bolts are loosened due to the vibration of the vertical frame 11. In order to solve such a problem, The interval adjusting bolt 18 is adjusted so that the position of the lock plate 16 can be adjusted to the position of the lock plate 13 The body 21 is inserted into the bolt B inside the transverse frame 12 while the gap adjusting groove 16a of the gold plate 16 is adjusted to engage with the gap adjusting groove 15a of the fixing plate 13, So as to keep the lock plate 16 in the closest contact state.

The lock bundle 31 provided inside the body 21 is coupled with the handle 32 and the guide shaft 35 so that when the knob 32 is pushed toward the lock projection 17, When the guide shaft 35 moves along the guide groove 23 located at the rear side of the guide groove 23 and moves to the rear side of the guide groove 23, the lock bundle 31 is inserted into the lock groove 17a of the lock projection 17, When the knob 32 is pulled out, the lock bundle 32 is disengaged from the lock groove 17a and the vertical frame 11 and the horizontal frame 12 are separated from each other, And the lock latch 36 is rotated about the fixed shaft 38 in the direction of the lock projection 17 so that the lock latch 36 is engaged with the lock projection 17b of the lock projection 17. [ When the lock jaw 37 is fixed, the lock piece 31 can be held firmly fixed to the inside of the lock projection 17 in a ratchet manner Therefore, the vertical frame 11 and the horizontal frame 12 can be firmly fixed to the vibration transmitted from the air conditioner or the vibration transmitted from the air filtering apparatus provided inside the clean room.

When the maintenance of the structure or the adjustment of the coupling state between the vertical frame 11 and the horizontal frame 12 is required, the locking protrusions 17b of the locking protrusions 17 The lock latch 36 is rotated in the direction in which the knob 32 is positioned and then the lock 32 is released from the lock groove 17a of the lock projection 17 by simply pulling the knob 32, The operator can easily recognize the current position of the lock plate 16 by using the fixed plate 13 and the scale display unit 19 formed on the side of the lock plate 16 to quickly change the moving distance or set the moving position to the original position There are also features that can be done.

The present invention improves the bolt fastening method used in various structures such as a conventional clean room by a bolt method, and can quickly perform a worker's handling and maintenance work. In addition, in the conventional bolt fastening method, the bolt is tightened and loosened It is possible to reuse the fixing device by applying the latching method which can solve the troubles that the bracket needs to be newly installed at a different position and especially the problems that the once used bolt can not be used again.

The frame failure device for a structure according to the present invention described above is not limited to the above-described embodiment, and can be applied to a frame failure device for a structure having a person skilled in the art without departing from the gist of the present invention There is a technological spirit to the extent that anyone can make various changes.
