Earthquake-proof apparatus for lightweight steel frame structure

The present invention relates to a lightweight steel frame including a plurality of carriers coupled to a plurality of hangers settled at the bottom of a slab, and a plurality of embosses coupled to be perpendicular to the bottom of the carrier, in particular, a dust-proof member installed at the end of the carrier Is supported by the elasticity of the wall, and when the vibration caused by the earthquake occurs, the vibration damping member compresses or expands and absorbs and disperses the vibrations. So far, the light steel frame is deformed or damaged due to slight or weak vibration. It relates to a seismic device for a lightweight steel frame when reducing damage on property.

In general, in order to improve the non-combustible material and smoothness, the ceiling slab of a building or the like is finished with a plasterboard. The method of attaching the gypsum board to the slab has been improved and used several times in consideration of its robustness and workability. Recently, a lightweight steel frame constructed by assembling lightweight steel frames as shown in FIG. 1 is frequently used.

The above-mentioned lightweight steel frame is, as shown in Figure 1, it is provided with a hanger (4) for fixing the carrier (6) at the bottom of the anchor bolt (2) fixed to the ceiling, the bottom of the carrier (6) The cross ('+') crosses the embar (8) refers to the fixed coupling.

The embar 8 provided at the bottom of the lightweight steel frame is combined with a texture, gypsum board, non-combustible material, etc., as described above, thereby forming a ceiling of the room.

That is, in the conventional lightweight steel frame, a plurality of hangers 4 are fixed in a row at regular intervals to form a single hanger 4 row, and this single hanger 4 row is spaced in a lateral direction. It is repeatedly installed to be spaced apart, and a plurality of hanger 4 rows are settled on the slab.

One hanger 4 column is fixedly installed as shown in FIG. 1 in each hanger 4 so that the carriers 6 are arranged in a straight line, and a plurality of hanger 4 columns are installed at the bottom of the carrier 6. As shown in Fig. 1, the embar 8 is coupled so that it intersects ('+') the carrier 6.

There have been problems such as human injury caused secondaryly.

Of course, when a strong earthquake occurs, it is not possible to solve the problem that the light steel frame is damaged or changed, but the fact that the light steel frame cannot withstand even a slight or weak strength is not a great strength, but it may be a great property damage. It is an urgent problem that must be corrected if we consider the possible human damage that can occur in the future.

The present invention has been devised to solve the above-mentioned problems, and by absorbing and dispersing horizontal vibrations and shocks transmitted from the wall surface to a certain size or less when a slight or weak occurrence occurs, damage and deflection of carriers and embars of a lightweight steel frame In order to prevent deformation, and furthermore, to provide a seismic device for a lightweight steel frame that can eliminate property damage and personal injury caused by the easy fall-off or damage of various construction materials such as texture, gypsum board, and lighting installed in the embar.

The construction and operation of the seismic device of the lightweight steel frame according to the present invention will be described with reference to FIGS. 3 to 6 as follows.

The above-described lightweight steel frame, as shown in Figure 3, a plurality of hangers 104 fixed to the slab, a plurality of carriers 106 coupled to the hanger 104, and disposed below the carrier 106 It consists of a number of embar (108).

As shown in Figure 3, the carrier 106 is coupled to a plurality of hangers 104 that are settled in a row on the slab, and the carrier 106 described above is generally extended from one end of the ceiling to the other. The hanger 104 is for the purpose of being installed in a straight line by fixing the hanger 104 so that it is installed in a straight line and fixing the position, and the carrier 106 is fixed at that position. Is installed.

And, the lower portion of the carrier 106 is arranged as shown in Figure 3 embar 108 is fixed to the carrier 106 coupled to the hanger 104 as described above.

The conventional carrier 106 is arranged to extend in a straight line from one wall surface to the other wall surface of the room, and its end is generally installed to contact the wall surface as described in the prior art.

However, the carrier 106 according to the present invention is the same as in the prior art that it is arranged in a straight line from one wall surface to the other wall surface of the room, but both ends of the carrier 106 are spaced apart as shown in FIG. 4. It can be said that it is installed.

On the other hand, the anti-vibration member 112, which is inserted and coupled to at least one of the one end and the other end of the carrier 106, is protruded from the end of the carrier 106 and is installed to abut against the wall surface, as shown in FIG. The anti-vibration member 112 has a structure that continuously presses the wall surface.

The anti-vibration member 112 may be composed of an elastic member, such as a coil spring or a leaf spring, and may adopt at least one of a gas shock absorber and a spring shock absorber as shown, and the present invention is not limited thereto. Can be variously adopted and changed.

The coupling means of the anti-vibration member for inserting and coupling the anti-vibration member 112 to the end of the carrier 106 will be described with reference to FIGS. 3 and 4.

First, since the anti-vibration member 112 is linearly arranged in the horizontal direction as shown in FIGS. 3 and 4, the wall surface must be pressurized to efficiently support the wall surface, so that the wall surface can be elastically supported. The anti-vibration bracket 120 is formed with a fixing part 122 formed of a groove structure inside to fix one end of the anti-vibration member 112, and one end of the anti-vibration member 112 is inserted into the fixing part 122. It is fixed in a fixed state.

In addition, the other end of the anti-vibration member 112 fixed to the fixing part 122 of the anti-vibration bracket 120 is to support the wall surface in a state protruding from the carrier 106, as shown, at this time, the anti-vibration As shown in FIG. 3, a seating portion 124 formed of a groove or hole structure is formed at the other end of the seismic bracket 120 so that the member 112 is linearly disposed in the horizontal direction.

As a result, one end of the anti-vibration member 112 is fixed to the fixing part 122 of the anti-vibration bracket 120, and the other part of the anti-vibration member 112 is seated or inserted into the seating part 124. Thus, a linear arrangement in the horizontal direction can be achieved.

In addition, the flange 121 is protruded on both sides of the other end of the anti-vibration member 112, as shown in FIG. 3, and when the earthquake-resistant bracket 120 is inserted into the carrier 106 as described below, it interferes with its end. By doing so, it no longer inserts into the carrier to perform a function.

When the anti-vibration member 112 is installed and fixed to the anti-vibration bracket 120 as described above, when the anti-vibration bracket 120 is inserted inside the end of the carrier 106 as shown in FIG. 3, the flange of the anti-vibration bracket 120 The position is fixed by the 121 being interfered with the end of the carrier 106.

On the other hand, Figures 5 and 6 is another embodiment of the coupling means of the anti-vibration member for coupling the anti-vibration member 112 to the carrier 106 according to the present invention, the seismic bracket is inserted into the carrier 106 at a certain depth A fixing part 122 capable of fixing one end of the anti-vibration member 112 is formed in the 120, and the anti-vibration member 112 is secured to the fixing part 122, preferably, FIG. As shown in the anti-vibration member 112, so that the rotation screw 140 can be freely rotated in the vertical direction through the fixing part 122 and one end of the anti-vibration member 112, the end of the rotation nut ( 142).

Therefore, the anti-vibration member 112 is free to rotate in the vertical direction around the rotation screw 140, and thus freely configuring one end of the anti-vibration member 112 absorbs and disperses vibration generated from the wall surface as much as possible. It is intended to be.

In addition, the other end of the anti-vibration member 112 fixed to the fixing part 122 of the anti-vibration bracket 120 is to support the wall surface in a state protruding from the carrier 106, as shown, at this time, the anti-vibration As shown in FIG. 5, a seating portion 124 having a groove or hole structure is formed at the other end of the seismic bracket 120 so that the member 112 is linearly disposed in the horizontal direction.

After all, one end of the anti-vibration member 112 is fixed rotatably to the fixing part 122 of the anti-vibration bracket 120, and the other part of the anti-vibration member 112 is seated or inserted into the seating part 124, thereby being horizontal. The linear arrangement toward the direction can be made.

After the anti-vibration member 112 is fixed to the seismic bracket 120 as described above, the seismic bracket 120 is inserted into the inner end of the carrier 106 as shown in FIG. 5.

Here, a plurality of through-holes 128 are formed on both sides of the carrier 106 as shown, and the coupling holes are arranged on both sides of the seismic bracket 120 in a straight line with the through-holes 128. 126) is formed.

Therefore, when the seismic bracket 120 is inserted into the carrier 106, the coupling hole 126 of the seismic bracket 120 and the through hole 128 of the carrier 106 are aligned with each other in a straight line. As shown in Fig. 5, if the coupling hole 126 and the through hole 128 coincide with each other, the fixing bolt 130 has a through hole 128, a coupling hole 126, and a coupling hole 126 as shown in FIG. , After passing through in the order of the through hole 128, by fastening the fixing nut 132 at its end, the seismic bracket 120 is to be inserted and coupled to the carrier 106.

On the other hand, the embar 108 is a component in which construction materials such as tex and gypsum board are directly coupled and installed, and it is necessary to have considerable strength in response to the vertical load by the building material, but in a small place, the vertical load Since it is not large, it is also possible to construct a lightweight steel frame.

However, since the carrier 106 is a basic skeleton in which all construction materials and electronic devices that can be installed on the ceiling must be installed, it must have considerable strength, and the coupling force between them must also be considerable.

As described above, since at least one of both ends of the carrier 106 according to the present invention is installed with a vibration-proof member 112 to elastically support the wall surface, vibrations transmitted from the wall surface during an earthquake occur in the carrier 106 as a whole. It is possible to absorb and disperse the vibration caused by the earthquake by repeatedly repeating the action that the vibration-preventing member 112 is compressed or expanded by the vibration according to the waveform of the earthquake before the impact.

The seismic device of the lightweight steel frame according to the present invention is not devised to prevent a building from being damaged or collapsed under the influence of an earthquake when an earthquake occurs, and most structures are constructed with structural seismic, vibration, and dustproof designs, Considering that most of the construction materials installed in the building are connected from the slab, the property is in the event that the light steel frame is bent or deformed easily, even if structural damage and human injury do not occur due to earthquake or weak earthquake. Of course, if the air conditioner, lighting, and interior parts or materials installed in the lightweight steel frame fall and fall due to the bending deformation and damage of the lightweight steel frame, it will not only cause damage to the person. It can be said to be a very good invention in that the durability of the lightweight steel frame can be further improved in response to the weak and fine lines, in view of the fact that it cannot prevent the loss of hands.
