Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, however, it is to be understood that the present invention is not limited to the disclosed embodiments.

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a ceiling frame installed to form a ceiling space separated from a lower space at an upper portion of an indoor space in a construction of a building.

2 is a partial perspective view of a ceiling frame 1 according to the present invention.

The ceiling frame 1 is provided with two or more first beam members 100 each having an inverted T-shaped cross section composed of a web W and a flange P provided on the end of each first beam member 100 A main beam 10 formed by joining in the longitudinal direction by the main clip 20 and having a plurality of through holes 11 in the web W and a main beam 10 composed of a web W and a flange P Two or more second beam members 300 having an inverted T-shaped cross section are formed in the longitudinal direction by being joined by the sub-clips 40 provided at the ends of the respective second beam members 300, A sub beam 30 passing through the through hole 11 of the main beam 10 and arranged at a right angle with the main beam 10 and a sub beam 30 fixed to the side of the building wall 2, And a beam of beams 50 on which both ends of the beam 10 and the sub-beam 30 are mounted.

The first and second beam members 100 and 300 constituting the ceiling frame 1 according to the present invention are formed in an inverted T shape in section like a beam for a general ceiling frame so that the ceiling finishing material is bonded to the flange P If a general ceiling frame beam is fixed to the lower surface of the upper slab by a lattice such as a tension member, the first and second beam members 100 and 300 have high rigidity, and the joints between the beam members are robust It can be fixed to the side surface of the wall body 2, not the bottom surface of the upper slab.

As a result, the fixing operation of the ceiling frame 1 can be smoothly carried out, and there is no obstacle such as a lunar calendar, so that the facilities can be more freely arranged in the ceiling space, and the dancing of the ceiling space can be made smaller As a result, the utilization rate of the lower space becomes higher.

Hereinafter, each of the structures of the ceiling frame 1 will be described in detail, and how the features of the respective structures cause the above-described effect will be described.

First, the first beam member 100 constituting the main beam 10 and the second beam member 300 constituting the sub-beam 30 will be described. 3 is a perspective view of the first and second beam members 100 and 300. As shown in FIG. The first beam member 100 and the second beam member 300 are similar in overall shape and several portions are different from each other, and the common features of the first and second beam members 100 and 300 will be described.

3 does not show configurations for coupling with the main clip 20 and the sub clip 40 and these configurations illustrate the coupling between the beam members 100 and 300 and the clips 20 and 40 Are shown in Figs. 6 to 9.

The first and second beam members 100 and 300 are manufactured by bending a single steel plate so that the center of its width coincides with the upper end of the web W so that the web W is sandwiched between the first face W1 and the second face W1, The web W includes a head portion WH and a first and second surfaces W1 and W2 on which a space S is formed between the first and second surfaces W1 and W2. Is formed by a lower leg portion WL tightly fixed by the tightening means A and a flange P formed horizontally protruding outward from the lower ends of the first and second surfaces W1 and W2 A plurality of grooves H are formed on the lower surface thereof, and a folding portion F formed by folding the end portion steel sheet downward at both ends of the width is provided.

The groove H is formed on the bottom surface of the flange P and the bottom surface of the flange P is not seen in the figure of Figure 3 or the like so that the groove H is formed at a position corresponding to the groove H on the upper surface of the flange P And reference numerals of the grooves (H) are shown at the protruding portions.

The head portion WH formed with the closed space S on the cross section is similar to the steel pipe and contributes to improving the sectional performance of the beam members 100 and 300 and is provided with a pair of legs WL, (F) also contributes to improving the cross sectional performance of the beam members 100 and 300. [

In order for the web W formed by the two faces of the first face W1 and the second face W2 to exhibit the effect of improving the end face performance, the first and second faces W1 and W2 are kept in close contact with each other, The cross-sectional shape of the member must be prevented from being deformed. The contact means A, which serves to maintain the contact state of the first and second surfaces W1 and W2, will be described separately in detail below.

The ceiling finishing material 4 is attached to the flange P by means of a screw N as shown in Fig. 4. A plurality of grooves H, which are formed on the lower surface of the flange P, So that the ceiling finishing material can be attached easily and firmly by fixing the position of the screw N so that the pointed end of the ceiling fin can be rotated only in one place.

When the screw N is fastened at the end of the width of the flange P, the end of the screw N pushes the flange P so that the screw N is not fastened to the flange P, Can be lifted up to the upper part. However, since the folding portion F is formed at the end portion of the width of the flange P of the first and second beam members 100 and 300, the partial rigidity of the first and second beam members 100 and 300 can be prevented.

As described above, the contact means A, which serves to maintain the close contact state of the first and second surfaces W1 and W2, has two slits parallel to each other passing through the first and second surfaces W1 and W2, (A2) formed by protruding a portion between the slits (A1) of the first and second surfaces (W1, W2) on one side of the web (W) And the outer peripheral portion of the slit A1 of the surfaces W1 and W2 is formed by an extension A3 formed by expanding into a space between the slits A1.

Fig. 5 is an explanatory view of the tightening means (A). Fig. 5 (a) is a tightening means A on a horizontal cross-sectional view, and Fig. 5 (b) is a tightening means A on a vertical cross-sectional view.

The contact means A is formed after a member having an inverted T-shaped cross section is formed of steel plates during the manufacturing process of the first and second beam members 100 and 300. The process of forming the adhesion means A comprises the steps of: i) forming two slits A1 parallel to each other through the first and second surfaces W1 and W2 on the leg WL of the web W, Pressing between the slits A1 so that the portion between the slits A1 of the first and second surfaces W1 and W2 protrudes beyond the web thickness at one side of the web; A1 so that the circumferential portions of the slits A1 of the first and second surfaces W1 and W2 are stepped below the thickness of the steel sheet at the other side of the web W. [ Since the surface of the binding portion A2 formed between the slits A1 in the step (i) is spaced apart from the other portions of the first and second surfaces W1 and W2, the first and second surfaces W1, W2 are fixed to each other so as not to be shifted in the longitudinal direction and the height direction. In the step ii), the steel sheet is thinned by pressing the periphery of the slit A1 and the slit A1 to be expanded into the space between the slits A1 Thereby forming the extension A3. The extension A3 prevents the first and second surfaces W1 and W2 from spreading in a direction perpendicular to the web W surface so that the first and second surfaces W1 and W2 are closely adhered tightly. It does.

Since the above-mentioned cohesion means A is formed by deforming the steel sheet itself constituting the beam members 100 and 300, the adhesion is not deteriorated over time and the bonding strength is excellent, as in the prior art of FIG. The web W is passed between a roller having a plurality of cutting blades per a circumference and a roller having a groove formed thereon and then passing the web W between a roller having a plurality of pressing punches formed around it and a roller having a groove, Since the means A can be formed quickly and continuously, it is possible to save time and cost in manufacturing the beam members 100 and 300.

As shown in FIG. 3 and the like, the tightening means A is formed by dividing a plurality of legs WL in the longitudinal direction at the center and the bottom of the dancing. Since the attachment between the first and second surfaces W1 and W2 is performed at two places of the dancing of the leg portion WL, the adhesion force between the first and second surfaces W1 and W2 is further increased, The tightening means A formed at the lower part of the dancing is provided with a screw N in the case where the screw N for attaching the ceiling finishing material 4 is fastened at the center of the width of the flange P, Thereby preventing the surfaces W1 and W2 from being opened.

Next, the main beam 10 and the sub beam 100 constituted by the respective beam members 100 and 300 are described in the first and second beam members 100 and 300 while explaining the different features of the respective beam members 100 and 300. [ (30) will be described.

6 is an explanatory view of the main clip 20 engaging the end portion of the first beam member 100 and the end portion of the first beam member 100. As shown in Fig.

The leg portion WL of the end of the first beam member 100 has a first coupling hole J1 passing through the first and second surfaces W1 and W2 and a second coupling hole J1 passing through the first coupling hole J1, And second and third coupling holes J2 and J3 formed at positions spaced apart from each other in the longitudinal center direction of the first beam member 100 and a cutting hole formed between the first and third coupling holes J1 and J3. And a wing 112b connected to the first and second surfaces W1 and W2 at a side of the cutout hole 112a in the direction of the third engagement hole J3 and spaced apart from one side of the web W The fixing pillar D is formed around the first to third coupling holes J1, J2 and J3 by protruding from the other side of the web by bending the first and second surfaces W1 and W2.

The main clip 20 is formed in a rectangular plate shape and includes a first coupling hole J1 at the center in the longitudinal direction and a second coupling hole J1 at a position spaced apart from the first coupling hole J1 toward the bottom side and one end in the longitudinal direction A locking hole 20a formed between the first and second coupling holes J1 and J2 and the second and third coupling holes J2 and J3 formed thereon and the first and third coupling holes J1 and J3 and a locking hole 20a formed at the other end in the longitudinal direction, (20b).

The one side and the other side of the main beam 20 of the first beam member 100 or both sides of the main clip 20 are denoted by the same reference numeral. This is because the direction in which the configuration is formed or the direction in which the configuration is formed has meaning.

The first beam member 100 and the main clip 20 are arranged such that the first beam member 100 and the main clip 20 are spaced apart from the first beam member 100 in a state where one side surface of the main clip 20 faces the other side surface of the first beam member 100, J2 and J3 of the main clip 20 after the fixing post D of the first beam member 100 is inserted between the coupling holes J1, J2 and J3, And they are joined together by bending outward.

The fixing post D forms a hole at each of the engaging holes J1, J2 and J3 of the leg portion WL and then presses the periphery of the hole at one side of the web W so that the peripheral portion protrudes to the other side . The outer diameter of the fixing pillar D is set to be smaller than the outer diameter of the first to third coupling holes J1, J2, J3 of the main clip 20 so that the fixing post D can be inserted between the first to third coupling holes J1, J2, J3 of the main clip 20. [ (J1, J2, J3).

Since the coupling holes of the first beam member 100 and the coupling holes of the main clip 20 are formed in three, respectively, the main clip 20 is fixed to the first beam member 100 without rotating about the coupling hole Lt; / RTI >

A tapered portion E for removing the contact means A may be formed at the end of the first beam member 100.

Since the binding portion A2 of the tightening means A protrudes from one side of the web W, when the first beam member 100 and the main clip 20 are engaged, the first beam member 100 and the main clip 20 may not be in close contact with each other. The tacking portion E prevents the tightening means A from being formed at the end of the first beam member 100 to which the main clip 20 is attached so that the main clip 20 is held in contact with the first beam member 100, The main clip 20 can be firmly engaged with the first beam member 100 without being disturbed by the contact means A.

A cutout groove C serving as a tongue E of the first beam member 100 may be formed at one end of the main clip 20. The cutout groove C allows the first beam member 100 and the main clip 20 to be engaged with each other so that the binding portion A2 of the contact means A can enter into the main clip 20 without interfering with one side of the main clip 20. [ ) Can be brought into close contact with each other.

The first beam members 100 are arranged in such a manner that the engaging jaws of the main clip 20 coupled to one first beam member 100 are spaced apart from the cut hole 112a of the first beam member 100, (20a) of the main clip (20) coupled to the main clip (100). 7 shows a state in which the first beam members 100 are joined together to form a main beam 10. In FIG.

When the ends of the first beam members 100 are brought into contact with each other, the engaging protrusions 20b of the main clip 20 coupled to one first beam member 100 and the incision holes 20b of the other first beam member 100 And the engaging hole 20a of the main clip 20 coupled to the other first beam member 100 are positioned at the same position and the engaging jaw 20b is positioned at the engaging hole 112a and the engaging hole 20a It gets caught. The wing 112b prevents the other end of the main clip 20 from moving in a direction perpendicular to the surface of the main clip 20 so that the engaging jaw 20b is inserted into the cutting hole 112a, Do not fall back on your back.

The latching jaw 20b is formed so as to be inclined from the other end of the main clip 20 toward the one end so that the latching jaw 20b can easily enter the cutout hole 112a and the like but can not easily come out.

The end of the blade 112b of the first beam member 100 may be bent obliquely outward to form the guide portion G. [ The guide portion G expands the opening of the gap formed between the wing 112b and one side of the web W so that the other end of the main clip 20 can easily enter the gap.

Likewise, the other end of the main clip 20 may be slightly bent in one lateral direction to easily enter the gap.

The main clip 20 is provided at a position between the first and second coupling holes J1 and J2 of the main clip 20 and the engaging jaw 20b at an oblique angle from one side of the main clip 20, A ramp R can be provided which abuts the distal end.

Since the first beam member 100 and the main clip 20 are tangent to each other and the first beam member 100 and the main clip 20 are in contact with each other, The ramp R forms an oblique slope that overcomes this step so that the other end of the main clip 20 is hooked to the stepped portion and the main clip 20 and the main clip 20 are separated from each other. 1 beam member 100 from interfering with each other.

The engaging protrusion 20b of the main clip 20 and the peripheral portion of the lamp R are bent at one side so as to form the engaging protrusion 20b and the ramp R so that the stiffness of the main clip 20 .

The upper and lower movement restricting protrusions 20c protruding from one side of the main clip 20 may be provided on the upper and lower ends of the section where the engaging protrusion 20b is formed on the length of the main clip 20.

The up and down movement preventing jaw 20c is engaged with the upper and lower sides of the cutting hole 112a of the first beam member 100 so that the first jaw 20b is engaged with the cutting hole 112a, Thereby preventing the main clip 20 from moving in the vertical direction, and thus the joint of the first beam member 100 can be made more rigid.

The upper and lower end portions of the main clip 20 are bent toward the other side to contribute to the improvement of the rigidity of the main clip 20. [

8 shows an explanatory view of the sub clip 40 which is coupled to the end of the second beam member 300 and the end of the second beam member 300. As shown in FIG.

The leg portion WL at the end of the second beam member 300 is formed with a seating portion M which is stepped on one side of the web W, The first and second surfaces W1 and W2 are formed around the first and second coupling holes J1 and J2 so that the first and second coupling holes J1 and J2 are formed through the surfaces W1 and W2, Thereby forming a fixing post D protruding from one side of the web W.

The sub clip 40 is formed in a rectangular plate shape. The sub clip 40 includes first and second coupling holes J1 and J2 vertically formed at one longitudinal end portion thereof, A jaw forming hole 40c formed between the first and second engaging holes J1 and J2 and the engaging hole 40b and an engaging hole 40c formed between the engaging hole 40b and the engaging hole 40b, (40d) formed by bending the upper and lower ends of the space between the lower jaw hole (40b) and the jaw forming hole (40c) so as to protrude from one side of the sub clip (40) And the peripheral portion protrudes from the other side of the sub clip 40 to form a jaw 40e.

The second beam member 300 and the sub clip 40 are arranged such that the first and second couplings 40 and 40 of the sub clip 40 are aligned in a state in which one side surface of the second beam member 300 faces the other side surface of the sub clip 40, The fixing pillar D of the second beam member 300 is sandwiched between the holes J1 and J2 and then the upper end of the fixing pillar D is coupled by bending it outwardly around each coupling hole of the sub clip 40. [

Since the method of joining the second beam member 300 and the sub clip 40 is not greatly different from the method of joining the first beam member 100 and the main clip 20, a detailed description of common parts will be omitted.

The coupling of the second beam member 300 and the sub clip 40 is made by two coupling holes unlike the coupling of the first beam member 100 and the main clip 20.

The subclip 40 can be positioned at the center of the width of the second beam member 300 by engaging the subclip 40 with the second beam member 300 in the seat M, Even if the second beam members 300 are coupled through the second beam member 40, the center of the width of each of the second beam members 300 coincides with each other.

The second beam members 300 are arranged such that the engaging portions 40a of the subclips 40 coupled to one second beam member 300 as shown in Fig. And the sub jaws 40e of the sub-clips 40 coupled to the sub-beams 40 to form the sub beams 30.

Since the coupling between the second beam members 300 through the sub clip 40 is made in the narrow through hole 11 of the main beam 10, the sub clips 40 coupled to each other are arranged in a direction perpendicular to the plane There is no need for a separate means to prevent movement.

The movement restricting jaw 40d is engaged with the web W of the main beam 10 to prevent the sub beam 30 formed by joining the second beam members 300 from moving in the longitudinal direction thereof Contributing to the improvement of the rigidity of the sub clip 40.

The flange P of the end of the second beam member 300 may be formed to be stepped upward by the thickness of the flange P of the first beam member 100.

The second beam member 300 is mounted on the flange P of the first beam member 100 so that a step is formed between the lower surface of the flange P of the second beam member 300 and the lower surface of the first beam member 100 The flange P of the second beam member 300 is formed to be stepped so that the flange P of the second beam member 300 can be prevented from being attached to the bottom surface of the second beam member 300. [ The lower surface of the flange P of the member 100 is formed on the same plane, and the above-described problems can be prevented from occurring.

A T-shaped angle holding member 60 may be formed at an intersection of the main beam 10 and the sub-beam 30 to maintain the main beam 10 and the sub-beam 30 at right angles. Fig. 10 is an explanatory view of the angle holding member 60. As shown in Fig.

The main beam 10 and the sub beam 30 intersect in the through hole 11 of the main beam 10 and the main beam 10 and the sub beam 30 are separated by the gap between the through hole 11 and the sub beam 30. [ The orthogonal state of the sub beam 30 can easily be turned and the straight state of the sub beam 30 at the joint of the second beam members 300 may not be maintained. This may be a factor that facilitates construction during the construction of the ceiling frame, but it may become a factor of degrading the ceiling frame after completion of construction. The angle holding member 60 serves to firmly hold the main beam 10 and the sub-beam 30 at right angles.

More specifically, the two sub legs 61, which are in line with each other in the angle holding member 60, have an ∩ shaped cross-section so as to surround the head portion WH of the second beam member 300, Shaped cross section and surrounds the head portion WH of the first beam member 100. A resilient arm B having a distal end facing the leg internal space is formed on the vertical surface of each leg, So that the head portion WH of the first and second beam members 100 and 300 is pressed.

The two sub legs 61 that are in line with each other allow the sub beam 30 to be maintained in a straight line state and the main leg 62 perpendicular to the sub legs 61 is supported by the sub beam 30, And the main beam 10 are fixed at a right angle so that the perpendicular angle between the main beam 10 and the sub beam 30 can be firmly maintained.

The pair of elastic arms B formed on each leg allows the angle holding member 60 to be tightly coupled to the first and second beam members 100 and 300.

Fig. 11 shows an explanatory view of the frame beam 50. Fig.

The edge beam 50 is formed of a vertical portion 51 and upper and lower horizontal portions 52 and 53 and has a U-shaped cross section. The outer side of the vertical portion 51 faces the wall body 2, The end portions of the main beam 10 and the sub beam 30 are fixed in a space between the upper and lower horizontal portions 52 and 53. The outer end of the width of the upper horizontal part 52 is folded upward to form a folding part F. A plurality of grooves H are formed on a lower surface of the lower horizontal part 53 and an outer end part of the width is folded down A folding portion F is formed.

As described above, since the first and second beam members 100 and 300 are excellent in cross-sectional performance and can be firmly joined in the longitudinal direction, the span of the main beam 10 and the sub beam 30 can be increased . The frame beam 50 serves to fix the ceiling frame 1 to the wall 2 of the building while supporting both ends of the main beam 10 and the sub beam 30 which are formed long.

The lower horizontal portion 53 of the frame beam 50 has a longer width than the upper horizontal portion 52 and facilitates the mounting of the main beam 10 and the sub beam 30, A plurality of grooves H are formed on the bottom surface of the main beam 10 in the same manner as in the flange P of the first and second beam members 100 and 300. The main beam 10 and the sub beam 30, So that the main beam 10 and the sub-beam 30 can be firmly fixed to the beam 50 by making it possible to rotate only one place without moving the end.

Similarly, the folding portion F of the lower horizontal portion 53 improves the rigidity at the width outer end side of the lower horizontal portion 53. When the screw N is fastened to the outer end portion of the width of the lower horizontal portion 53 And prevents the portion (N) from being lifted upwards by the screw (N).

The folding portion F formed in the upper horizontal portion 52 also improves the rigidity of the edge beam 50. [
