Embodiment 1

2 is an exploded perspective view showing the grating according to the first embodiment of the present invention, and FIG. 3 is a plan view showing the grating.

Referring to the drawings, the grating 100 includes a plurality of grating components 110, a connection bar 140 for coupling the grating components 110 to each other, and an odor prevention unit.

The grating component 110 and the connection bar 140 may be made of stainless steel, aluminum alloy, synthetic resin, plastic, FRP, or the like. The grating component 110 is formed by bending a flat metal plate, and two edge portions facing each other of a substantially rectangular metal plate are vertically bent to form the support part 112, and the rectangular part inside the support part 112 is It becomes the body part 113. In addition, both ends of the support part 112 are coupled to the connection bar 140.

It is preferable that the support part 112 is formed on the long side of the body part 113. This is because, after arranging a plurality of grating components 110 in the horizontal direction, if the connecting bar 140 is installed on the short side, the grating 100 having a long side width w can be made.

The main body 113 has a substantially rectangular shape, preferably a rectangular shape. The main body 113 is preferably extended slightly more outward than the support 112, and accordingly, the coupling of the end of the support 112 and the connection bar 140 is made under the main body 113. This structure is advantageous because the coupling can be protected by the body portion 113.

Embossing 117 may be formed at both ends of the main body 113 to protrude downward. The embossing 117 allows spot welding that combines the main body 113 and the horizontal portion 144 to be efficiently performed. As is known, spot welding is a method of bonding two metals by supplying electricity after contacting two metals. If there is no embossing 117, there is a disadvantage that the amount of electricity consumed for welding increases.

As an alternative to the embossing being formed on the body portion 113, the embossing may be formed to protrude upward from the horizontal portion 144.

Preferably, a groove 114 may exist between the end of the support part 112 and the body part 113. After the horizontal portion 144 is inserted into the groove 114, it may be combined with the embossing 117 by spot welding.

A plurality of drain holes 111 and non-slip protrusions 116 may be formed in the main body 113. The drain hole 111 is formed to penetrate the main body 113, and may be formed by first drilling a through hole in a metal plate, and then expanding the through hole (burring processing). A flange portion (111b in FIG. 9A) and a curved portion 111a are formed in the drain hole 111 by the expansion (burring processing).

Although a circular drain hole 111 is shown in the drawing, a drain hole 111 of various shapes may be formed within a limit capable of smoothly discharging water (excellent water, etc.).

A curved portion 111a may be formed around the upper end of the drain hole 111 and a flange portion 111b may be formed below the circumference of the drain hole 111. The flange portion 111b serves to increase the load-bearing force of the body portion 113. The drain hole 111 is provided with a stopper 150 for preventing odor or a stopper for preventing slip, which will be described later.

On the other hand, the non-slip protrusion 116 is formed to protrude upward from the main body 113.

The connection bar 140 is a strip-shaped rod formed long in the longitudinal direction, and couples two or more grating components 110 to each other. The connection bar 140 is coupled by welding to the end of the body part 113 and the embossing 117 and/or the end of the support part 112. It is preferable that the connection bar 140 has the same length as the length of the grating 100 to be made.

The connection bar 140 not only couples the grating components 110 to each other, but also serves to increase (reinforce) the load bearing capacity of the grating.

형상의 단면을 가질 수 있다. 상술한 바와 같이, 본체부(113)는 지지부(112) 보다 바깥쪽으로 약간 더 연장되는데, 이에 따라 수평부(144)가 홈(114)에 삽입되었을 때 연결 바(140)는 본체부(113)의 아래에 위치하게 된다. 이러한 구조는 연결 바(140)가 본체부(113)에 의해 보호될 수 있고,

형 단면 구조가 I형 단면 구조보다 직하중에 대한 저항력 및 비틀림 응력에 대한 저항성 높고 효율성이 높으므로 유리하다. The connection bar 140 may include a vertical portion 142 and a horizontal portion 144 extending horizontally from an upper end of the vertical portion 142. That is, the connection bar 140 is

It can have a cross-section of a shape. As described above, the main body 113 extends slightly more outward than the support 112, and accordingly, when the horizontal part 144 is inserted into the groove 114, the connection bar 140 is the main body 113 It will be located under the In this structure, the connection bar 140 may be protected by the main body 113,

The type cross-sectional structure is advantageous because it has higher resistance to direct load and torsional stress than the I-shaped cross-sectional structure and has higher efficiency.

In place of the mold section,

Mold cross section or

It can also have a type cross section.

As shown in Figs. 2 to 3, after arranging the support parts 112 of neighboring grating components 110 to contact each other, the horizontal part 144 is inserted into the groove 114, and the horizontal part 144 and the embossing ( When 117 is welded (spot welding, etc.) and the end of the support part 112 and the vertical part 142 are welded, neighboring grating components 110 are coupled to each other by the connection bar 140. Welding may be used for the coupling of the connection bar 140 and the main body 113, and for coupling the ends of the connection bar 140 and the support 112, but other conventional coupling means such as bolting and rivets may also be used. .

The grating 100 does not require the bearing bar 3 and the cross bar 4 (cross bar installed on the upper surface of the grating) of the existing grating 1 because the support part 112 supports the load. In the past, it took a lot of time and cost to manufacture and combine (welding) the bearing bar 3 and the cross bar 4, but the grating 100 according to the present invention is a bearing bar 3 and a cross bar 4 Because it is not required, product unit cost and manufacturing time can be reduced.

The odor prevention unit seals the drain 111 so that the odor does not rise upward, but when a predetermined amount of water is accommodated in the drain 111, it rotates downward so that the water is discharged downward.

As shown in FIGS. 2 and 4A to 5B, the odor prevention unit may include a coupling portion 151, a odor prevention stopper 153, and a gap-holding material 159.

The coupling portion 151 is a rod-shaped member, formed to extend long along the length direction of the main body 113, and is coupled to the lower surface of the main body 113. The coupling part 151 may be made of metal, plastic, rubber, aluminum alloy, or the like. In addition, the coupling portion 151 may be coupled to the lower surface of the body portion 113 by adhesive, double-sided tape, welding, or the like.

As shown in FIGS. 4B and 6A to 6B, a groove line 152c is formed on a surface facing the odor preventing stopper 153 in the coupling portion 151 to extend long. Specifically, as shown in FIGS. 6a to 6b, the coupling portion 151 includes a flat plate portion 152a and two side portions 152b formed to be inclined vertically or close to the vertical in the flat plate portion 152a. The groove lines 152c are formed by the side portions 152b of the dogs formed on the flat plate portions 152a at predetermined intervals.

The flat plate portion 152a is coupled to the lower surface of the body portion 113. Further, a first protrusion 152d is formed at the inner end of the two side portions 152b, and a second protrusion 152e is formed at the outer end of the two side portions 152b, respectively.

When the protrusion line 156 is inserted into the groove line 152c, the first protrusion 152d is fastened to the groove 156a at the lower end of the protrusion line 156, so that the coupling part 151 and the stopper 153 for preventing odor Is concluded. To this end, the two side portions 152b can be bent outward when the protrusion line 156 is inserted into the groove line 152c, and when the insertion is completed and the first protrusion 152d is fastened to the groove 156a, the original It is desirable to have elasticity and restoring force to the extent that it can be returned to the shape of.

And, when the space retaining member 159 is fitted into the coupling portion 151, the coupling portion 151 and the distance are maintained by the fastening protrusion 159a of the space retaining member 159 being fastened with the second protrusion 152e. The material 159 is fastened. It is preferable that the outer surface of the second protrusion 152e is formed to be inclined to facilitate the fastening. When the spacing member 159 is fitted into the coupling portion 151, when the fastening protrusion 159a moves along the inclined surface, the spacing member 159 opens to the side, and the fastening protrusion 159a and the second protrusion ( When the fastening of 152e) is completed, the gap holding member 159 that has been opened is returned to its original shape. To this end, the spacing member 159 preferably has an elastic force and a restoring force.

As shown in FIGS. 1 and 9a to 9b, the coupling portion 151 is preferably installed to extend long along the longitudinal direction of the main body 113 between the flange portions 111b of the two drains 111, This structure is advantageous because the coupling portion 151 can be protected by the flange portions 111b on both sides, and is also advantageous in ensuring that the stopper 153 is in close contact with the lower end of the flange portion 111b.

Meanwhile, FIGS. 7A to 7B show modified examples of the coupling part 151. First protrusions 152d are formed on both sides of the inner surface of the coupling part 151. The first protrusion 152d may be fastened to the lower end of the protrusion line 156. This coupling part 151 can be effectively used when the gap holding material 159 is not required, for example, when the odor preventing stopper 153 is provided integrally, which will be described further in the second embodiment. It should be.

The odor prevention stopper 153 includes a connection part 154, a cover part 155 formed at the end of the connection part 154, and a protrusion line 156 formed to protrude from the connection part 154 and coupled to the coupling part 151 It may include. The odor prevention stopper 153 may be made of plastic, rubber, steel, aluminum alloy, etc., but is not limited thereto.

The protrusion line 156 is formed to be elongated along the longitudinal direction of the coupling portion 151 in the connection portion 154. As described above, the cap 153 is coupled to the lower surface of the coupling portion 151 by inserting and fastening the protruding line 156 into the home line 152c. Specifically, a groove 156a is formed at the lower end of the protrusion line 156, and when the protrusion line 156 is inserted into the groove line 152c, the first protrusion 152d is fastened to the groove 156a. Thus, the stopper 153 is coupled to the coupling portion 151.

In this way, when the stopper 153 for preventing odor is detachably fastened to the coupling part 151, only the damaged stopper 153 needs to be replaced when the stopper 153 is damaged, so maintenance and repair are convenient and economical. In contrast, in the case where a plurality of stoppers are integrally formed, it is disadvantageous because the entire stopper must be replaced even if only some of the stoppers are damaged.

The connection part 154 is preferably made of a material having elasticity, and this is to allow the cover part 155 to return to its original state after being rotated downward due to the weight of the water thereon. That is, when the water contained in the upper part of the cover part 155 exceeds a predetermined weight, the cover part 155 rotates downward while overcoming the elastic force of the connection part 154 as shown in FIG. 9B, and when the water is removed, the connection part ( The cover portion 155 is returned to its original position by the elastic force of 154).

The cover portion 155 may include an edge portion 155a and an insertion guide portion 155b extending so as to protrude from the edge portion 155a. In the drawings, the cover part 155 is shown to be formed at both ends of the connection part 154, but the cover part 155 may be formed only at one end of the connection part 154.

The insertion guide portion 155b has an upwardly convex shape to be inserted into the drain hole 111 and has a shape that matches the drain hole 111, but has an outer diameter slightly smaller than the inner diameter of the drain hole 111. Accordingly, the insertion guide portion 155b can be easily inserted and removed from the drain hole 111 (that is, the insertion guide portion 155b is not forcibly fitted into the drain hole 111). By the insertion, separation of the cover part 155 in the left and right directions may be prevented.

And, when the insertion guide portion 155b is inserted into the drain hole 111, the upper surface of the insertion guide portion 155b is preferably lower than the surface (upper surface) of the grating 100, which is This is to allow some water to be stored at the top.

The rim portion (155a) is in close contact with the lower end of the flange portion (111b) by the elastic force of the connection portion (154). The rim portion 155a and the insertion guide portion 155b cooperate with each other to seal the drain 111 to prevent an odor from rising.

It is preferable that the odor prevention stopper 153 is inclined at a predetermined angle θ toward the main body 113 around the protrusion line 156 at the center, as shown in FIGS. 5A to 5B. This is to prevent the odor from rising by allowing the cover part 155 to come into close contact with the lower end of the drain hole 111, and to return to its original position after the cover part 155 is rotated downward as shown in FIG. 9B.

The angle (θ) is preferably 1˚ to 15˚. If the angle (θ) is less than 1˚, it is not preferable because the odor may rise due to insufficient adhesion of the cover part 155, and if the angle θ is greater than 15˚, rainwater is stored on the cover part 155 Even in this case, there may be a problem that the cover part 155 does not rotate downward.

As an alternative to the angle θ or together with the angle θ, as shown in FIGS. 10A to 10B, an elastic member 157 may be embedded in the odor preventing stopper 153.

The elastic member 157 may be buried in the odor preventing stopper 153 along the longitudinal direction (direction perpendicular to the coupling portion) of the odor preventing stopper 153, the center or both sides of the odor preventing stopper 153 Can be buried in.

The elastic member 157 provides an elastic restoring force so that the stopper 153 can return to its original position after being rotated downward and extends the life of the stopper 153.

As the elastic member 157, a rod-shaped spring, a square leaf spring, or the like may be used. In addition, the spring may be made of steel, plastic, stainless steel, or the like.

In the above, a structure in which the cover part 155 includes the rim part 155a and the insertion guide part 155b and the insertion guide part 155b protrudes upward has been described, but as shown in FIGS. 11A to 11B, the cover part ( The 155 may be formed in a plane having an area covering the drain hole 111, but may have a structure in which the cover part 155 and the connection part 154 are formed to be inclined toward the body part 113 around the protrusion line 156. Since the stopper 153 has an inclination angle θ, the cover part 155 may be in close contact with the lower end of the drain hole 111.

On the other hand, the gap holding member 159 is installed on the coupling portion 151 to maintain a constant interval between the odor preventing stopper 153. The spacing member 159 has a length corresponding to the spacing between the plugs 153.

형상의 단면을 갖는데, 그 끝단에는 내측으로 돌출된 체결 돌기(159a)를 구비한다. 도 4b에 나타난 바와 같이, 간격 유지재(159)가 결합부(151)에 끼워질 때, 체결 돌기(159a)는 제2 돌출부(152e)에 체결된다. 체결 돌기(159a)가 제2 돌출부(152e)에 체결되면 간격 유지재(159)가 결합부(151)에 고정되므로 마개(153)의 위치가 고정되고, 이에 따라 덮개부(155)가 배수구(111)에서 이탈하는 것을 방지할 수 있다. As shown in Figs. 8a to 8b, the space keeping member 159 is

It has a cross-section of a shape, and has a fastening protrusion 159a protruding inward at its end. As shown in FIG. 4B, when the space retaining member 159 is fitted into the coupling portion 151, the fastening protrusion 159a is fastened to the second protruding portion 152e. When the fastening protrusion 159a is fastened to the second protrusion 152e, since the spacer 159 is fixed to the coupling part 151, the position of the stopper 153 is fixed, and accordingly, the cover part 155 is 111) can be prevented.
