Description

Apparatus for preventing secession between grating}

The present invention relates to a departure preventing device of the grating, and more particularly to a departure preventing device of the grating to prevent the grating located in the middle in the state installed so that several gratings are connected.

In general, the grating is composed of a plurality of bearing bars and crossbars intersecting the inside of the frame so that the grating is placed on a frame buried in the upper part of the drainage side of the road to filter out large foreign substances from entering the drainage. It is used to help.

On the other hand, the grating used for the above uses may be installed by connecting several gratings according to the installation place or drainage conditions, and frequent theft accidents occur when the grating is simply placed on the frame as described above. As a result, as the economic loss increases, various types of locking devices are provided, which not only has a complicated structure but also requires a lot of time for installation.

In order to solve this problem, the present inventors proposed a utility model registration No. 289052 "connecting device of the grating" that can be installed by connecting the gratings in a simple and simple manner as a simple structure as a simple structure. Referring to Figure 4 as follows.

3 is a perspective view illustrating main parts of a grating having a conventional connection part, and FIG. 4 is a cross-sectional view of main parts illustrating a state of use according to FIG. 3.

As shown, the insertion portion 120 to which the coupling member 125 composed of the coupling piece 122 and the insertion piece 124 is coupled to the front end frame 110A of the frame 110 constituting the grating 100. The connection portion formed of a coupling groove 130 having a jaw portion 134 formed therein is formed and the coupling groove 132 into which the connection member is inserted into the other end frame 110B of the frame 110 corresponding thereto. It is provided.

As described above, the grating and the grating had an advantage of being easily connected to each other in a short time by the insertion part and the coupling groove formed at the front end and the other end.

However, in the case of the grating having the connection part, when the grating positioned in the middle thereof is applied to the upper side due to the large physical pressure, the grating positioned in the middle part is separated because no locking means is provided. The same theft had the problem of concern.

Accordingly, the present invention is to improve the utility model registration No. 289052 "Grating apparatus" filed and registered by the present applicant in order to solve the conventional problems as described above, the purpose of which is to continuously It is simple and easy to connect and at the same time prevent gratings in the middle.

The present invention for achieving the above object, to form an insertion portion is coupled to the connecting member consisting of a coupling piece and the insertion piece to the front end frame of the frame, the insertion of the connecting member to the other end frame of the frame corresponding thereto In the grating having a connecting portion consisting of a coupling groove is formed in the engaging groove is formed, the engaging groove is formed and the coupling piece is placed, the separation preventing member is formed at the end of the lower side frame of the connecting member than the tip of the connecting member It is coupled to be positioned inward and characterized in that it has a departure prevention portion formed with a locking step formed on the bottom of the other end frame.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention in more detail as follows.

1 is a schematic perspective view showing the present invention.

As shown, the front end frame 110A of the frame 110 forms an insertion part 120 to which the coupling member 122 composed of the coupling piece 122 and the insertion piece 124 is coupled, and corresponding thereto. Grating 100 having a connection portion consisting of a coupling groove 132 is formed with a coupling groove 132 into which the insertion piece of the connection member is inserted into the other end frame 110B of the frame. )

The present design is a known coupling so that the separation prevention member 10 formed with a locking piece 12 bent upward at the end by the lower side frame 110C of the connecting member 125 is located inward than the front end of the connecting member. The separation prevention part 30 is coupled to each other by welding or the like, and has a locking step 20 formed on the bottom surface of the other end frame 110B to be secured to a height at which the locking piece of the separation prevention part can be inserted. It is shown.

In the above, it is preferable that both ends of the insertion piece of the connecting member and the engaging piece of the separation prevention member are provided with respective cutting portions 124a and 12a which are chamfered so that attachment and detachment can be made more easily.

2A to 2C are views showing a state of use of the present invention, and FIG. 2A is a sectional view showing main parts of a state in which a grating and a grating are connected.

As shown in the drawing, the insertion piece 124 of the connection member 125 coupled to the front end frame 110A, which is the insertion part 120 of one side grating, is formed of the other end frame 110B of the other side grating. It is shown to insert by connecting to the coupling groove 132 of the coupling groove 130.

Therefore, a plurality of gratings can be installed by simply and easily connecting to each other continuously within a short time through a connection part consisting of an insertion part and a coupling groove part formed at each front end and the other end.

2B is a sectional view showing the principal parts of the one-side grating before raising the upper side thereof.

In the above configuration as shown, the connecting member 125 coupled to the front end frame 110A of the grating to the other end frame 110B of the other side grating in order to separate one grating in the state of FIG. 2A In the formed coupling groove 132 is shown a state slightly advanced by the flow width of the coupling groove.

Figure 2c is a sectional view of the main part showing a state in which one side grating is caught by the separation prevention portion.

In the above configuration as shown, in the state of Figure 2b in the state of one side of the gripping end frame 110A to be lifted to the upper side of the bent engaging of the stopper 10 coupled to the lower portion of the connecting member The piece 12 is caught by the catching jaw 20 formed at the bottom of the other end frame 110B of the other side grating so as not to be separated.

Therefore, the grating located in the middle portion cannot be released unless the grating is sequentially released from one end in the state where several gratings are installed, and thus, the grating is prevented from being stolen.

As described above, the present invention not only can easily and conveniently connect several gratings to each other by the insertion part of the insert part and the coupling groove part in succession, but also the grating located in the middle of the gratings which are installed by the separation prevention part. It is possible to prevent the theft, thereby preventing theft of the grating.
