The present invention relates to a light-weight steel frame ceiling installation, more specifically, a lightweight steel frame structure in an apartment-type building, a small size and easy to manufacture, and at the same time the ceiling frame installation can be easily selected up and down and left and right It's about a phrase.

Conventionally, various lightweight steel frame structures have been disclosed. Representatively, two types will be described below. 1 is related to the conventional lightweight steel frame assembly structure, it is a representative view of the Korean Utility Model Application No. 20-1999-0022630.

The prior art comprises: a plurality of fixed woods (12) having a long length and parallel to the ceiling slab (11) at regular intervals; Is formed to have a long length is fixed to each side of the wood 12, a plurality of hooks 15 are formed at a predetermined interval at the bottom and a clip bar 14 formed with a plurality of fixing holes 17 along the longitudinal direction and ; An M bar 18 positioned perpendicular to the clip bar 14 and coupled to the hook 15 of the clip bar 14; Made of gypsum board 19 fixed to the M bar 18, it is a lightweight steel frame assembly structure.

This is because the clip bar 14 is fixed to the horizontal line previously filled with wood 12, and then the M bar 18 is fixed to the clip bar 14 so that the horizontal state of the gypsum board 19 is adjusted. The main purpose is to make.

However, this method has a limitation in that it is not possible to sufficiently adjust the horizontal state of the ceiling. This is because the height inequality may occur at least 5 centimeters (cm) when concrete is poured. Therefore, a structure for height adjustment is needed.

2 is a view of a conventional structure for installing a light steel ceiling frame, showing a structure capable of height adjustment.

The technique disclosed in Korean Utility Model Application No. 20-1996-0041056 includes: a ceiling fixing member 1 embedded in a concrete forming a ceiling; A position adjusting member 2 inserted and fixed to the ceiling fixing member 1 and having a plurality of locking ends 2a 'formed on both sides thereof; The locking end 2a 'of the position adjusting member 2 is inserted into the channel 13 and the like to form a long hole (13a) to be coupled; The ceiling fixing member 1 has a substantially rhombic shape and has a position reference flange 1a that forms an insertion groove K opened at its center portion, and forms a circle around the insertion groove K. Hollow cylinder 1b having protruding jaws 1f, 1f '; 1g and 1g', and cover 1h having an angle limiting jaw protruding to form a predetermined angle while being fitted into the upper portion of the hollow cylinder 1b. On the other hand; The positioning member 2 has a locking portion 2a having a plurality of locking ends 2a 'to be coupled to the channel 13 and the ceiling fixing member 1 while forming an upper portion of the locking portion 2a. It is characterized by consisting of a fixing portion (2b) forming an approximately T-shape to be inserted into the insertion groove (K) of the.

By the way, the above structure can be adjusted up and down, but there is a limit that can not be adjusted in the horizontal direction (channel embar) in the horizontal direction. In addition, there is a disadvantage that the state of engagement with the embar after the position adjustment is not stable, while the production of the position adjustment member is difficult.

In general, the only components in which the conventional positioning member or channel (hanger) holds the embar are only the needle-shaped protrusions. Therefore, in particular, when the embar is forced upward, a problem arises, for example, when installing plywood (gypsum board) in the embar. That is, there is a problem that the coupling state of the embar and the hanger is not firmly shaken.

On the other hand, in ordinary buildings, two-stage lightweight steel structures are used to suspend embar from ceiling concrete. However, in buildings with low ceiling space, such as apartments, it is generally not appropriate to use a two-stage type.

Therefore, sufficient length adjustment is possible without having a long length in the up and down direction, and a structure that is stable in engagement with the embar is required. At the same time, the simpler the structure, the simpler the fabrication will be.

The present invention is to solve the necessity as described above, and as a lightweight steel frame structure (small) size (height) can be used even in the low ceiling, can be easily moved to change the position of the embar, such as up and down and left and right, to manufacture Its purpose is to provide a ceiling frame fitting that is easy, easy to install, and stable.

In the present invention for achieving the above object, in the light-weight steel ceiling structure installation fixture, which includes a hanger for binding to the insert portion consisting of a bolt and a nut and holding a bar (bar) for ceiling surface installation; In the hanger, a first arc-shaped auxiliary film 42 and a second arc-shaped auxiliary film 44 through which the bolt of the insert portion passes are further formed in the hanger body portion 40; The space 43 is located between the two auxiliary membranes transversely through the hanger body portion 40, the nut space 43, which can be placed while the nut is coupled with the bolt is further formed. .
Hereinafter, with reference to the accompanying drawings, embodiments of the configuration according to the present invention will be described in detail.

Figure 3a is a view showing an example of a light steel hanger according to the present invention.

3A shows an insert consisting of a bolt 31 head, a threaded body 32 of the bolt, and nuts 331, 332, and a hanger is shown. The head 31 of the bolt is inserted into the insert member in the concrete of the ceiling. Figure 3a is a photograph taken a seated wooden bar for installing the ceiling surface in Figure 3a.

In FIG. 3A, the hanger is banded to form quadrilateral faces 341, 342, 343, 344, 345 as a whole. The first surface 341 is the upper surface, and a hole through which the bolt 31 of the insert portion penetrates is formed. Preferably, one nut 331, 332 is placed above and below the first surface 341.

The second surface 342 of the hanger is bent at one end of the first surface and extends downward, and the third surface 343 is bent at the second surface to form a bottom surface. A bar for ceiling installation will be placed on the inner side of the third side 343.

The fourth side 344, 345 of the hanger is divided into two parts. The first portion 345 extends downwardly by bending at the other end of the first surface (opposite to the second surface). The second portion 344 bends and extends upward in the third surface. As can be seen in Figure 3a, a fastening protrusion 37 is formed on the outer surface of the second portion 344, the first portion 345 corresponding to the fastening protrusion 37 (height and shape The corresponding fastening groove 36 is formed.

Positions of the projections 37 and the grooves 36 formed on the fourth surface of the hanger may be selected relatively freely, and various shapes may be selected. In order to simplify the manufacture of the hanger, a necked rectangular projection 37 and a small rectangular groove 38 are preferably formed as shown.

In addition, the second surface 342 of the hanger is preferably formed with a support projection 38 inwardly. Thus, it is possible to prevent the wooden bar for installing the ceiling placed on the third surface 343 from moving upward when the plywood is pasted. In this case as well, it can be easily formed by using a part of the second surface 342 of the hanger as shown in the drawing.

Since the material of the hanger as a light steel frame is a metal having elasticity and ductility, the first part of the fourth surface 345 can move in the direction of the arrow shown. Thus, the rectangular protrusions 37 formed in the second portion may be fitted into the rectangular grooves 38 formed in the first portion. In addition, the protruding angle of the support protrusion 38 and the fastening protrusion 37 may also be adjusted by applying a force to the worker because it is metal.

After the fourth side of the hanger is divided into two parts and the wooden bar for ceiling installation is settled, the reason for binding the protrusion 37 and the groove 36 is that the wooden bar is very long. In order to be installed in the second or fourth direction.

Such a hanger is an example of a one-stage ceiling frame fitting suitable for low ceilings such as apartment buildings. Since the ceiling plywood is nailed to a wooden bar, the distance from the bottom surface of the ceiling to the actual ceiling (plywood) is equal to the length of the length of the body 32 of the bolt plus the longitudinal length of the second side 342 of the hanger. Will be.

4A shows a hanger member as another embodiment of the present invention.

Referring to FIG. 4A, a first arc-shaped auxiliary film 42 and a second arc-shaped auxiliary film 44 are formed in a hanger body part on a hanger, and a nut space (between the two auxiliary films 42 and 44) is formed. 43) is further formed. In addition to the left and right protrusions 47 and 49 for mounting the M bar, hanger blades 46 and 48 are further formed.

The body of the bolt (32 in FIG. 3A) is inserted into the upper hole 41 of the hanger of the first arc-shaped auxiliary film 42 of the hanger. At this time, after the nut 33 is placed in the nut space 43 to bind the bolt and the nut, the body 32 of the bolt continues to pass through the second arc-shaped auxiliary membrane 44 to hanger lower portion 45. You can go down.

The two auxiliary membranes need not necessarily be circular (cylindrical), but may be circular enough to support the body of the bolt in the transverse direction. In addition, if the nut space 43 is formed so as to penetrate the hanger body portion 40 laterally, the body 40 of the hanger may be a thin plate shape. However, it is preferable that the portion 45 through which the bolt passes up and down slightly be grooved.

In FIG. 4A, when the bolt and the nut 33 bind in the nut space 43, the first auxiliary film 42 and the second auxiliary film 44 are supported (position fixed) together. Since the bolt body 32 can continue to the lower end of the hanger 45, it is possible to adjust the up and down position of the hanger.

Figure 4b shows a hanger member as another embodiment of the present invention, like Figure 4a, the body of the bolt is a hanger member that can move along the dotted line.

In the hanger of FIG. 4B, at one side of the body portion of at least one of the left and right protrusions 47 and 49, protruding vanes 46 and 48 which are able to contact the upper end of the embar are further formed. In the figure, the protruding vanes on both sides are in the same direction (for clear representation), but it is preferable that the vanes protrude in different directions.

Since the protruding directions of the protruding vanes 46 and 48 are intended to support and fix the embar from above when the embar is forced upward, it is preferable to protrude in the longitudinal direction of the embar. The embodiment of FIG. 4A and the embodiment of FIG. 4B illustrate some of the various protruding aspects, and it is important to form the winged protrusions.

The slight difference between FIG. 4B and FIG. 4A is also in the inlet portion into which the body 32 of the bolt is fitted. In FIG. 4A, a cylindrical auxiliary film is formed on the basis of a flat plate hanger. In FIG. 4B, the upper end of the hanger body 40 is bent twice, once slightly bent and once bent in a substantially perpendicular direction. In this case, the first auxiliary layer 42 may be a flat plate.

In FIG. 4B, a hole 41 through which the body 32 of the bolt passes is formed at the bent (laterally) upper end of the hanger. The bolt body passing through the upper end hole 41 may be coupled with a nut placed in the nut space 43.

FIG. 5 is a photograph of a sample for a hanger member that is slightly different in appearance from FIG. 4A or 4B but basically the same.

On the other hand, Figure 6 shows a rail-shaped insert member to adjust the position in the horizontal direction according to the present invention, Figure 7 is a sample photograph according to the embodiment.

It is an insert member embedded in the concrete forming the ceiling, and has a cross section of a vertical light narrowing with respect to the vertical direction so as not to fall out naturally after the concrete is poured. That is, the width of the upper end 52 of the insert member may be longer than the width of the lower end 53. FIG. 6 illustrates a cross section of an inverted trapezoidal shape in a simple basic form.

In the insert member of the present invention, the body 51 extends in a horizontal direction, and an insert space 55 is formed to communicate from the outside of the concrete bottom 56 to the center of the body, and the center has a width greater than the cross-sectional width of the insert space. In a larger width, a railed horizontal space 54 is formed.

When the insert space 55 and the central horizontal space 54 are combined, a T-shaped shape is formed in the cross section. Thus, after the bolt having the lateral shape (i.e., the head is flat) is fitted, it can be moved horizontally without naturally falling out.

The tee-bolt may be fitted before concrete pouring, or in some of the long bodies 51 of the insert member, the width of the insert space 55 is as large as the width of the horizontal space 54, as shown in FIG. 7. You may.

The hanger according to the present invention described above and the insert (bolts and nuts), the insert member, and the embar can be combined in combination.

8 is a photograph of a light steel frame ceiling installation device according to one embodiment.

Of course, as another example of the combination, the dish-shaped hanger and the rail insert member are also possible. As will be appreciated by those skilled in the art, a hanger in which a protruding wing is omitted or a part of an auxiliary barrier is omitted may be screwed together with the rail insert member.

9 is a view showing a hanger member for a light steel frame as another example of the present invention. In FIG. 9, a hanger displayed in a three-dimensional shape at an upper side thereof may be manufactured by folding a flat plate whose dimension is shown as an example.

The hanger represented in FIG. 9 is largely provided with a support surface 92 supporting a wooden beam for installing a ceiling surface, contact surfaces 91 and 93 in close contact with the side surfaces of the wooden beam, and horizontally from the contact surface 91 to the ceiling surface. It consists of a protruding surface 94 that protrudes outward.

Here, when the hole 951 through which the bolt 31 of the insert part penetrates is formed in the protruding surface 94 of the hanger, a nut is attached to each of the upper and lower sides of the protruding surface 94 when the bolt is fitted into the hole 951. By positioning, it is possible to adjust and fix the position of the hanger in the vertical direction.

In addition, the contact surfaces 91 and 93 of the hanger are preferably formed with at least one hole for fixing the lumber 974, 983. An elongated timber may be seated on the hanger, which is a dish-shaped support, and a hole is formed to fix the nail with a nail or the like so that it does not shake when the ceiling surface is installed.

In the illustrated example, two fixing holes 974 are formed on the left and right sides of the space 961 in which the protruding surface 94 is formed on the first contact surface 91 of the hanger, and the second height is relatively low. Three fixing holes 983 are formed in the contact surface 93 at intervals. The operator will be able to nail the lumber fastening nails through the holes 974 and 983 in the appropriate positions as needed.

Using the hanger member shown in FIG. 9, the distance from the bottom surface of the ceiling concrete to the ceiling surface can be made very short. That is, since the position of the insert bolt can be adjusted from the side of the hanger, the distance as much as the height of the hanger can be omitted, and the minimum possible spacing can be the length of the screw body of the tee-type bolt. In general, the length of the bolt, the thickness of the lumber, or the height of the first contact surface 91 of the hanger is affected.

Those skilled in the art will understand that various combinations of the above-described hangers and the insert member described above may be various lightweight ceiling frame fittings capable of horizontal and vertical positioning.

The present invention having the configuration as described above can be installed even in a low ceiling, such as an apartment-type building as a one-stage ceiling frame installation. In addition, while the size of the hanger, which is the central element in the ceiling frame installation port, the body portion is plate-like, there is an advantage that it is relatively easy to manufacture.

In addition, the hanger according to the present invention includes two auxiliary membranes having a simple structure to stably bind the bolt and the nut, and includes two protruding wings to stably support the embar suspended from the hanger in the vertical direction. . Thus, there is a ripple effect that makes it easy to install the ceiling plywood.

Overall, the rail-type insert member allows the selection of the position in the horizontal (left and right) directions while using the bolt for easy up and down adjustment, and the binding state of the bolt and the nut can be adjusted at the same time. Position selection is possible. That is, according to the present invention can adjust the position of the ceiling frame (hanger and embar) up, down, left and right, there is a ripple effect that facilitates the ceiling frame construction.
