Description

An assembling structure of a frame for mounting ceiling boards}

The present invention relates to a frame mounting structure for attaching a ceiling finish, and more particularly, for attaching a ceiling finish such as gypsum board, for attaching a ceiling finish that can achieve a significant reduction in workmanship and defect rate as well as material savings. The present invention relates to a frame mounting structure.

In a typical concrete building ceiling, a number of ceiling finishes are attached in consideration of internal aesthetics.

However, the process of attaching the ceiling finishing material is not performed by direct contact between the ceiling surface of the concrete and the ceiling finishing material, but by inserting a plurality of anchor bolts at a suitable depth into the ceiling, and based on these anchor bolts. By installing a separate frame consisting of a carrier (carrier) and M-bar (M-bar) thereon, and the step of attaching a plurality of ceiling finishes one by one on the frame.

The present invention is to optimize or rationalize the installation structure of the frame for attaching the ceiling finish.

According to FIG. 1, which shows a conventional frame installation structure for ceiling finishing material, the ceiling finishing material attachment frame 10 includes a plurality of anchor bolts 11 lattice-shaped in a ceiling of a concrete building and a curved plate having an “n” shape. And a carrier 12 inserted into a plurality of long holes h drilled in the longitudinal direction on the upper end surface thereof and fastened to a nut at the lower end of the anchor bolt 11, and also in the longitudinal direction at the lower end of the carrier 12. It is configured to include an M-bar 13 is engaged with a plurality of protrusions formed by.

The anchor bolt 11 has a structure including an insertion part 11-1 having a substantial portion thereof embedded in the ceiling and a screw part 11-2 fastened to the lower end of the insertion part 11-1. .

On the other hand, reference numeral 14 and "s" denote ceiling finishing materials and fastening members, respectively.

In installing the frame for attaching the ceiling finishing material of the conventional structure as described above, since it is necessary to perform a hard work such as drilling (drill), nut fastening work while looking up the ceiling of the building, it will inevitably take excessive effort and time. There was no choice but to.

Since the installation work of the frame for attaching the ceiling finish is difficult, it is difficult to accurately drill a plurality of drill holes, that is, anchor bolt insertion holes, unless a skilled and careful worker is installed.

That is, the anchor bolts in the inserted state are not arranged along straight lines (L1, L2, hereinafter referred to as "design lines") in the construction plan, but sometimes deviate significantly from these design lines.

However, as shown, in order to seamlessly couple the carrier 12 and the M-bar 13 to each other to form a complete frame 10, first, the anchor bolts deviated from the design lines L1 and L2. (11) Even if the lower end is forced, the nut N must be pulled into the long hole h on the upper face of the carrier 12.

Such that the lower end of the anchor bolt 11 located away from the design lines L1 and L2 and the long hole h on the top surface of the carrier 12 are forced to form a rectangular or square shape in the drawing. The work requires considerable effort and time, while at the same time causing severe deformation or residual stresses throughout the frame.

As a result, the installation of the frame for attaching the ceiling finishing material does not only require excessive labor input, but even after the completion of the work, defects such as the gypsum board falling off due to the above-described deformation or residual stress are used. did.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a frame installation structure for attaching a ceiling finishing material that can significantly reduce the labor and defect occurrence rate in attaching the ceiling finishing material as a building ceiling finishing material.

In addition, the present invention has an additional object to provide a frame mounting structure for mounting the ceiling finish material that can reduce the material required to install the frame for attaching the ceiling finishing material.

The object of the present invention as described above is achieved by disposing a separate connecting member between the anchor bolt and the carrier.

That is, according to the frame installation structure for attaching the ceiling finishing material according to the present invention, the anchor bolt is characterized in that the connection member receives or absorbs the degree of deviation from the design line, that is, construction error.

Accordingly, the anchor bolts and the carrier can be simply joined without any deformation to the anchor bolts or carriers, provided the anchor bolts are not arranged outside a certain error range.

Hereinafter, the frame installation structure for attaching the ceiling finishing material according to the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

According to FIG. 2, which shows a frame mounting structure for attaching a ceiling finishing material according to an embodiment of the present invention, the ceiling finishing material attaching frame 100 includes a plurality of anchor bolts 110 embedded in the ceiling at an appropriate depth, and an anchor bolt 110 at a central portion thereof. The coupling member 150, which has a long hole H for interlocking with the construction member and absorbs a construction error, and the mutual coupling portion of the coupling member 150 and the mutual coupling portion of the carrier 120 can be simultaneously engaged with them. Interlocked with the clip (160) of the structure, the carrier 120 having a plurality of engaging projections at its lower end, and engaging with the mating engaging portion on the clip (160), and the engaging projection at the lower end of the carrier (120) It is configured to include a combined M-bar (13).

In the drawings, "d1" and "d2" indicate the degree to which the anchor bolts 110 located at the points "B" and "C" deviate from the design lines L1 and L2, that is, their respective constructions. Error.

In addition, "q" represents a portion where the clip 160 is coupled on the carrier 120, and the mutual coupling relationship between them will be described later.

Meanwhile, in the case of the M-bar 13, the same reference numerals as in the related art are attached, whereas in the case of the anchor bolt 11, a separate reference numeral 110 is attached.

This is because, as shown in Fig. 3, the anchor bolt 110 in the present invention is different from the conventional structure in that the length adjusting groove is formed on the lower end face of the threaded portion 110-2.

The length adjusting groove is a groove into which a tool tip such as a driver can be inserted. If the height of the lower end of the anchor bolt 110 is different due to the ups and downs of the ceiling or significant construction failure, the length adjustment groove is provided in the length adjusting groove. By inserting a screwdriver or the like to match the height of the lower surface of the screw unit (110-2).

In addition to the length adjusting groove, the screw portion 110-2 includes an extension portion m having a radially extended shape between the cylindrical portion having an appropriate diameter constituting the lower end portion thereof and a screw forming portion extending upwardly thereof. The following locking groove n is provided.

The locking groove n is a portion to be engaged with the long hole H on the connection member 150 mentioned above.

That is, the connecting member 150 is suspended from the lower end of the anchor bolt 110 through the engagement between the long hole (H) of the central portion and the engaging groove (n).

The shape or structure of the insertion portion 110-1 corresponding to the upper half of the anchor bolt 110 is the same as in the conventional case.

As shown in FIG. 4, the connecting member 150 has a long hole H in the center thereof, and one end thereof is a plate member bent at a right angle.

The long hole H is not merely a long hole, but extends in the longitudinal direction of the connection member from the circular hole portion H1 formed at one end of the connecting member 150 and the circular hole portion H1. , A linear hole portion H2 having a width smaller than the diameter of the circular hole portion H1.

The circular hole segment H1 has a corresponding dimension as a portion where the lower circumferential body portion on the anchor bolt thread portion 110-2 is inserted, while the width of the linear hole portion H2 is the anchor bolt thread portion 110. -2) as a portion to engage with the engaging groove (n) on the relative movement also has a corresponding dimension.

In addition, cutouts (w) are formed on both side surfaces of the connection member (150), and the outer leading end of the cutout (w) is a connection member (150) except its root portion, that is, the cutout (w). ) It has a structure that protrudes about 0.5 mm from the whole upper surface.

Here, with reference to FIG. 6, which is a perspective view of the clip as described above, the shape of the clip 160 itself as well as the mutual relationship with the connecting member 150 will be described.

First, prior to explaining the feature of the shape of the clip 160, it will be determined from the concept or reference for the front and rear and left and right directions.

That is, the clip 160 attaches importance to the point where the clip 160 is coupled to the connecting member 150, so that the front end portion that is first contacted with the connecting member 150 during the mutual coupling therebetween is "front end", and vice versa. The tip is referred to as the "back end".

As shown, the clip 160 is bent upwardly in a "c" shape, while the opposite side ends thereof face each other, while the rear end thereof is bent downward in a "c" shape, the front end of which is at right angles. It is a plate of a shape bent downward.

The upwardly bent portions formed at both side end portions are referred to as the "interconnecting portion with the connecting member 150" mentioned above, and the downwardly bent portions formed at the rear end thereof are also referred to as "reciprocal coupling portions with the carrier 120". Each will be configured.

That is, the interval p 'between the two upwardly bent portions on the clip 160 has a dimension corresponding to the width p of the connecting member 150, and the "c" shaped downward bent portion of the rear end portion. And the gap q 'between the right angled downward bend of the front end portion has a dimension corresponding to the top surface width q (see FIG. 2) on the carrier 120 mentioned above.

Therefore, both upward bent portions on the clip 160 serve to hold the connecting member 150, while downward bent portions serve to hold the carrier 120.

Referring to Figure 6, when described the mutual coupling process between the anchor bolt 110, the connection member 150 and the clip 160 as follows.

First, when the circular hole portion H1 on the connection member 150 is inserted into the bottom of the anchor bolt 110 embedded in the building ceiling and simultaneously pushes the connection member 150 to the side, as mentioned above, The connection member 150 is suspended from the bottom of the anchor bolt 110.

Separately, the “c” shaped downward bent portion on the clip 160 is inserted into one end of the carrier 120. (Arrow ①)

Although one clip 16 is shown to be fitted on the carrier 120, in practice, it is necessary to fit as many clips 160 as the number of anchor bolts 120 associated with the same design lines L1 and L2.

Subsequently, the plurality of clips 160 bring the carrier 120 with the upper end face fitted onto the connecting member 15. (Arrow ②)

In this case, since the lower end of the anchor bolt 110 protrudes below the connection member 150, as indicated by the arrow, the anchor bolt 110 should bypass the lower part of the anchor bolt 110.

Then, using a small hammer or the like, lightly hit the connecting member 150 toward both upward bent side on the clip 160. (Arrow ③)

If the ceiling of the building itself is slightly severe, the vertical position of the bottom of the anchor bolt 110, that is, the height is different, so that the connecting member 150 and the clip 160 are shifted from each other, anchor bolt screw 110-2 By inserting a screwdriver or the like into the length adjusting groove on the bottom surface, the connection member 150 in a state suspended from the lower end of the anchor bolt 110 can be matched with the clip 160.

As can be seen in FIG. 7, where the cutout w on the connecting member 150 passes through both upward bent portions on the clip 160, the cutouts w on both sides of the connecting member 150 are formed. Due to its elasticity, it is slightly pressed down from the inlet of the upward bent portion and passes through the entire upward bent portion.

Once passed through the upward bend on the clip 160, again due to its elasticity, the cutout w is restored back to its original shape (a structure that protrudes 0.5 mm from its root).

That is, the cutout portion w on the connection member 150 passes through both upwardly bent portions on the clip 160 and cannot be caught by the rear end thereof.

In other words, a strong mutual coupling is made between these connecting members 150 and the clip 160.

In view of the fact that the cutouts w formed on both sides of the connecting member 150 must pass through a narrow gap called an upward bend on the clip 160, the cutouts are on the cutouts w as shown. It is preferable to slightly incline the side of the first contact with the upward bent portion on the clip 160 in terms of reducing the resistance at the time of mutual coupling.

On the other hand, as can be seen in Figure 2 is a state where a rigid mutual coupling between the connecting member 150 and the clip 160, the clip 160 to block the circular hole portion (H1) on the connecting member 150 Therefore, once the coupling between the connection member 150 and the clip 160 is made in at least one place, there is no fear that the carrier 120 or the like falls from the anchor bolt 110 during operation.

After the series of carriers 120 are coupled to the bottom of the entire anchor bolt 110 through the above working process, the top openings on the M-bars 13 are inserted into the plurality of coupling protrusions formed on the bottoms of the carriers 120. Just put it.

Thus, despite the large construction error of "d1", "d2" on Fig. 2, because no deformation need to be applied to the anchor bolt 110, carrier 120, etc., the frame for attaching the ceiling finish very quickly You can complete the installation.

In addition to the above-described significant workmanship saving effect, as can be guessed from FIG. 2, the carrier 120 for installing the ceiling finish attaching frame in the present invention is mounted on the " n " shaped carrier 12 in FIG. Since it is not necessary to have both side wall portions as in the above, the effect of material savings is exhibited accordingly.

As described above, the frame mounting structure for attaching the ceiling finishing material according to the embodiment of the present invention has been described in detail, but those skilled in the art will be able to make various modifications or changes within the scope of the present invention.

For example, the case where anchor bolt of a structure different from the figure is used, or when changing the cross-sectional shape of a carrier can be assumed.

However, it should be understood that all minor design changes, such as a structure that accommodates or absorbs the anchor bolt-related construction errors by arranging a connection member between a plurality of anchor bolts and a carrier embedded in the ceiling, are within the technical scope of the present invention. will be.

As described above, according to the frame installation structure for attaching the ceiling finishing material of the present invention, in attaching the ceiling finishing material, such as gypsum board, it is possible to obtain a significant reduction in workmanship and defect rate as well as the effect of saving materials.

Considering the fact that the share of labor costs in construction sites is increasing day by day, it is believed that the frame installation structure for attaching the ceiling finishing material according to the present invention will show a great degree of economic effect in the related industrial field.
