Description

Grating manufactured by coupling grating components made from metal plate and, grating assembly manufactured by coupling the grating}

The present invention relates to a grating, and more specifically, to a grating component by bending a rectangular metal plate to be made by combining the grating component in a horizontal direction, it is possible to quickly and easily install the odor prevention stopper in the drain and drain The stopper is installed in the stopper to prevent random departure, and the stopper installed in the drain to prevent the slippery to filter foreign matter, and to prevent the random departure, and is made of a combination of a number of grating components to be easily made in various widths and shapes And the manufacturing process is for simple and productive gratings.

The grating 1 having the structure as described above has a problem that it takes a lot of work time and cost to manufacture and weld the end bar 2, the bearing bar 3, and the cross bar 4, respectively.

In addition, since the grating 1 has a structure in which the bearing bar 3 and the cross bar 4 are provided inside the rectangular space formed by the end bar 2, the shape and / or the width thereof cannot be easily changed. There is a problem that the grating of the width and shape must be repeatedly installed. If the shape and / or the width of the grating 1 is to be changed, the end bar 2, the bearing bar 3, and the cross bar 4 need to be newly manufactured, which is time-consuming and expensive.

On the other hand, the grating 1 has a plurality of rectangular holes (lattices) formed by the end bar 2, the cross bar 4 and the bearing bar 3, but there is a problem that odor rises through the holes.

However, since the rectangular hole is a passage through which rainwater moves to the bottom, for example, a drainage channel, the rectangular hole must be kept open and the rectangular hole must be sealed to prevent odor. Because they collide with each other, odor blocking is not easy.

In order to solve the above problem, the present applicant has developed a grating made by processing a metal plate, such as bending and burring, and has filed and registered it as Korean Patent Application No. 10-2016-0148047.

In FIG. 3B, the arrow indicates that the lid 85 of the stopper 80 is rotated and opened.

However, the stopper 80 is installed in such a way that the operator directly inserts into each drain 17, there is a problem that the installation takes a lot of time and labor. In addition, the stopper 80 is installed in a manner that is fitted to the drain port 17, there is also a problem that if the external load is applied is often lost from the drain port 17.

Furthermore, the grating 90 notches and bends four edges of the metal plate P to form the first and second support parts 21 and 25, respectively, between the first and second support parts 21 and 25. Since a gap of a predetermined interval must be formed, the manufacturing process is complicated and high precision is required.

The present invention has been proposed to solve the above problems, and an object thereof is to provide a grating that can be easily made in various widths and shapes because a plurality of grating components are horizontally combined.

The present invention is an improvement and modification of the grating of the Republic of Korea Patent Application No. 10-2016-0148047, the contents of the patent application publications are all included herein.

First embodiment

Figure 4 is an exploded perspective view showing a grating according to the first embodiment of the present invention, Figure 5 is a plan view showing a metal plate for manufacturing the grating component constituting the grating.

Referring to the drawings, the grating 100 includes a plurality of grating components 110, a connection bar 140 that couples the grating components 110 to each other, and a closure unit 150. The grating component 110 and the connecting bar 140 may be made of steel, stainless steel, aluminum alloy, synthetic resin, plastic, FRP, or the like.

The grating component 110 is formed by bending a flat metal plate 101, and two edge portions of the metal plate 101 facing each other are vertically bent to form a support 112, which is an inner side of the support 112. The rectangular portion becomes the main body portion 113. In addition, both ends of the support part 112 form a coupling part 114.

Specifically, the edge portion of the metal plate 101 is vertically bent around the dotted line d1 to be the support part 112, and both ends of the support part 112 are vertically bent around the dotted line d2 to be coupled. Part 114 is achieved. Coupling portion 114 is perpendicular to the support portion 112 and the body portion 113, respectively.

The support portion 112 is preferably formed on the long side of the main body portion 113. This is because arranging the plurality of grating components 110 in the horizontal direction and then installing the connecting bar 140 on the short side can make the grating 100 having the width of the long side (w in FIG. 6A).

The main body 113 has a substantially rectangular shape, preferably a rectangular shape. Body portion 113 is preferably formed to extend slightly more outward than the support portion 112, whereby the coupling portion 114 is located below the body portion 113, the coupling portion 114 and the connection bar Coupling of the 140 is also made under the main body 113. This structure is advantageous because the coupling of the coupling portion 114 and the connection bar 140 can be protected by the body portion 113.

And, there is a gap 115 between the upper end of the coupling portion 114 and the body portion 113, the interval 115 to facilitate the bending of the coupling portion 114. In addition, an upper end of the connection bar may be inserted into the gap 115, which will be described in the second embodiment below.

On the other hand, the metal plate 101, as shown in Figure 4, the embossing 118 may be formed to protrude outward. The embossing 118 is to facilitate spot welding, and may be selectively formed on the support 112 and the coupling part 114. As is known, spot welding is to close the two metals and then supply electricity to combine the two metals. If there is no embossing 118, there is a disadvantage in that the electricity consumption for welding increases.

Embossing may be formed on at least one of the two support portions 112 facing each other when the two grating components 110 are arranged adjacent to each other, such that the protruding embossing 118 and the support portion 112 are in contact. Spot welding can be made well.

In addition, an embossing 118 may be formed on at least one of the surfaces of the coupling part 114 and the connection bar 140 facing each other. In FIG. 4, there is no embossing 118 in the connecting bar 140 and an embossing 118 is formed in the coupling part 114, but an embossing 118 is formed in the connecting bar 140 and the coupling part 114. Embossing 118 may not be formed in the.

The main body 113 may have a plurality of drain holes 111 and anti-slip protrusions 116. The drain 111 is formed to penetrate the main body portion 113, and may be formed by drilling a through hole in the metal plate 101, and then expanding (burring) the through hole. Although a circular drain 11 is shown in the drawing, drain holes 11 of various shapes may be formed within a limit capable of smoothly discharging water (such as excellent water). A curved portion 111a is formed around the upper end of the drain 11, and a flange 111b is formed below the circumference of the drain 111. The flange portion 111b serves to increase the load bearing force of the main body portion 113. The drain hole 111 may be provided with a odor preventing cap 150 or a slip preventing plug, which will be described later.

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

The connecting 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 preferably has the same length as the length of the grating 100 to be made.

The connecting 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. An embossing 118 may be formed in the connection bar 140, which has been described above.

As shown in FIGS. 4 and 6A-6B, after the support 112 of the neighboring grating component 110 is placed in contact with each other, the connecting bar 140 is brought into close contact with the coupling part 114 and welded (spot welding). Etc.), the connecting bar 140 and the coupling part 114 are combined to complete the grating 100. Welding may be used for coupling the connection bar 140 and the coupling part 114 and for coupling the support parts 112 to each other, but other conventional coupling means such as bolting and riveting may be used.

The grating 100 does not need 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 112 supports the load. Conventionally, the manufacturing and bonding (welding) of the bearing bar 3 and the cross bar 4 takes a lot of time and cost, but the grating 100 according to the present invention is such a bearing bar (3) and cross bar (4) This eliminates the need for cost savings in product cost and manufacturing time.

The stopper unit 150 seals the drain hole 111 so that the odor does not rise upward, but when water of a predetermined weight is accommodated in the drain hole 111, the stopper unit rotates downward to discharge the water downward.

As shown in FIGS. 6A-8B, the closure unit 150 includes a support 151 and a closure 153.

Support 151 is a bar coupled to the lower surface of the main body 113. Preferably, the support 151 is installed to extend in the longitudinal direction of the main body portion 113 between the flange portion (111b) of the two drain holes (111).

The stopper 153 may include a connection part 154 coupled to the support 151 and a cover part 155 formed at an end of the connection part 154. The cover 155 may include an edge portion 156 and an insertion guide portion 157 extending to protrude from the edge portion 156. Although the cover part 155 is illustrated as being formed at both ends of the connection part 154, the cover part 155 may be formed only at one end of the connection part 154.

The stopper 153 may be made of plastic, rubber, steel, aluminum alloy, or the like, but is not necessarily limited thereto.

The connecting portion 154 is coupled to the lower surface of the support 151 by welding (spot welding or the like) or bonding (adhesive). And, the insertion guide portion 157 has a convex shape upward so that it can be inserted into the drain port 111, the insertion guide portion 157 has a shape to match the drain hole 111 and slightly smaller than the inner diameter of the drain hole 111 With an outer diameter, the insertion guide portion 157 can be easily inserted into and removed from the drain hole 111 (that is, the insertion guide portion 157 is not forcibly fitted into the drain hole 111). By the insertion, the left and right deviation of the cover portion 155 can be prevented.

In addition, when the insertion guide portion 157 is inserted into the drain hole 111, the upper surface of the insertion guide portion 157 is lower than the surface (upper surface) of the grating 100, and thus the upper portion of the insertion guide portion 157 Some water may be stored.

The edge portion 156 is in close contact with the lower end of the flange portion 111b by the elastic force of the connecting portion 154. The edge portion 156 and the insertion guide portion 157 cooperate with each other to close the drain hole 111 to prevent odors from rising.

The connecting portion 154 is preferably made of an elastic material, which is intended to allow the cover portion 155 to return to its original state after rotating downward due to the water load thereon. That is, when the water contained in the upper portion of the cover 155 exceeds a predetermined weight, as shown in FIG. 8B, the cover 155 rotates downward while overcoming the elastic force of the connecting portion 154, and when the water is removed, the connecting portion ( The cover 155 is returned to its original position by the elastic force of 154.

According to the present invention, after the stopper 153 is coupled to the support 151 at a predetermined interval (the interval between the drains), the stopper 151 is coupled to the lower surface of the main body portion 113 by a plurality of stoppers 153 at once. It can be installed in the drain 111, thereby reducing the labor and cost for installing the stopper.

On the other hand, the existing odor prevention stopper is manufactured by attaching one or two gratings on a basis of one grating, which requires a lot of steel plate materials and parts, resulting in high cost, large weight, and complicated parts and functions. Odor protection is lost throughout the drain. However, the closure unit 150 according to the present invention has a low problem for failure because each cover portion 155 is applied only to each of the drains and the structure is simple, and partial replacement is possible in case of failure, and thus the life of the odor prevention function is very long. The material of the stopper is spring plate or rubber, plastic, etc., and it is easy to handle and weight because it is made lightweight and lightweight.

In addition, because the stopper 153 is fixed to the support 151, the stopper 153 can be prevented from being separated from the drain hole 111 arbitrarily.

A plurality of drain holes 111 may be formed in the main body 113, and a odor preventing stopper (not shown in FIG. 9) or an anti-slip stopper (not shown in FIG. 9) may be selectively installed in the drain hole 111.

Grooves 112a are formed at the lower end of the support part 112 at predetermined intervals along the longitudinal direction of the main body part 113, and the grooves 112a are inserted into and coupled to the lower rods 112b. The lower rod 112b is installed to penetrate through the plurality of supports 112 to prevent the support 112 from being twisted or bent due to the load.

General grating is most vulnerable when the vehicle moves in a direction perpendicular to the bearing bar 3, the grating 100 according to the present invention is the bottom rod in a direction perpendicular to the longitudinal direction of the grating component 110 to compensate for this. 112b is provided in the groove 112a.

The connecting bar 110, as shown in Figures 10a to 10c, the upper end thereof extends in the horizontal direction. The extended portion 142 is inserted between the main body portion 113 and the support portion 112, and preferably, the extended portion 142 is welded to the lower surface of the main body portion 113. Thus, the connecting bar 140 not only couples the grating components 110 to each other but also serves to support the load acting on the body portion 113.
