Description

Cover apparatus for an opening

The present invention relates to an opening cover device which can easily cover openings of various sizes and increase the rigidity of the cover plate.

In the construction site, openings such as cavities or halls are formed between floors or floors of the building as necessary, and openings are usually formed on the floor for the purpose of transporting construction materials or installing equipment, devices, piping, or similar components. . Since the opening is formed and it is dangerous to leave the opening as it is, the upper side of the opening is covered with a plate-shaped board or a rectangular cover in accordance with the shape and size of the opening.

Since the openings vary greatly in size and shape, it is difficult to use the opening cover once used in other workplaces, and thus various types of opening covers are disclosed, which can be used regardless of the size of the opening, thereby improving recyclability.

As the opening cover, Korean Utility Model Model No. 0426326 has a cover plate 10 having a plurality of bolt holes 12 penetrating from top to bottom, as shown in FIG. 1, and the cover plate 10. The L-shaped fixing bracket 20 having the bolt hole 22 corresponding to the bolt hole 12 of the cover plate 10 is bolted to the cover plate 10 at the lower portion thereof, so that the cover is removed from the opening. It can be installed to fit openings of various sizes.

In addition to the Korean Utility Model Utility Model No. 0426326, Korean Utility Model Utility Model No. 0398872, Korean Utility Model Model No. 0426299, Korean Patent Registration No. 0677189, and Korean Patent Application Publication No. 2009-0019592 are disclosed.

By the way, the opening cover disclosed in the prior art has a structure in which many bolt holes are formed in the cover plate at regular intervals, and the fixing bracket is fixed by using bolts in accordance with the size of the opening, so that the fixing bracket is caught on the inner surface of the opening. Due to this, there is a problem that the cover plate is broken by unexpected impact due to the weak rigidity of the cover plate due to many bolt holes, and if the distance between each bolt hole is increased to increase the rigidity, it is difficult to accurately fix the fixing bracket to the inner surface of the opening. Since it is difficult, there is a problem that the cover is detached, and in order to move and fix the fixing bracket, it is necessary to completely loosen the bolt and fix it by inserting the bolt into another bolt hole, so assembling work according to the size of the opening is not easy and the fixing bracket or the bolt and There were problems such as missing nuts and lost.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide an opening cover device that can be precisely covered in various sizes of openings, easy to assemble and increase the rigidity of the cover plate.

The opening cover device according to the present invention for achieving the above object is a cover plate for covering the opening, a fixing bracket which is fixed to the bottom surface of the cover plate and caught on the inner surface of the opening, and a fixing member for fixing the cover plate and the fixing bracket It includes, The cover plate is characterized in that the sliding long hole is formed to move and fix the fixing member.

It is preferable that a plurality of protrusions are formed on a surface of the fixing bracket which is caught on the inner surface of the opening to increase frictional force.

The edge of the cover plate is formed with a coupling hole to engage the joint means for connecting the other cover plate in accordance with the size of the opening.

The cover plate is provided with a handle that moves up and down to easily handle the cover plate and whose end portion is caught by the bottom of the cover plate.

The sliding long hole is formed with a sliding receiving groove to accommodate the head of the fixing member.

According to the opening cover device according to the present invention, while increasing the rigidity of the cover plate, it is easy and accurately fit to the openings of various sizes, the friction force is increased so that the cover plate is not detached, and fixed while easily moving without completely loosening the fixing member Since the bracket can be fixed, there is an effect of facilitating the assembly work according to the size of the opening and not losing the fixing bracket or the fixing member.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is an exploded perspective view showing a first embodiment of the opening cover device according to the present invention, Figure 3 is a cross-sectional view of the opening cover device is assembled and installed according to the first embodiment of the present invention. As shown, the opening cover device 100 of the present invention is fixed to the cover plate 110 covering the opening portion (S) and the bottom surface of the cover plate 110 is fastened to the inner surface of the opening (S) 120 and a fixing member 130 for fixing the cover plate 110 and the fixing bracket 120. In the first embodiment of the present invention, the openings S are rectangular, and the fixing brackets 120 are fixed to one side of each of the rectangular openings S one by one.

The cover plate 110 is provided with a pair of sliding long holes 111 in two rows to move and fix the fixing member 130 in accordance with the size of the opening (S). The sliding long hole 111 is formed long in the vertical direction from the center of the cover plate 110 toward each side.

The fixing bracket 120 has an angle shape, and two holes 121 are formed to fit the fixing member 130 inserted into the pair of sliding long holes 111.

The fixing member 130 is in the form of a bolt, but may be in the form of a screw, the screw portion 131 passes through the sliding long hole 111 and the hole 121 in the bottom surface of the fixing bracket 120 It is fixed by the nut 132. The washer may be inserted into the screw portion 131 of the fixing member 130 as necessary.

As shown in FIG. 3, the opening cover device 100 configured as described above is configured to align the outer surface of one flange of the fixing bracket 120 with the inner surface of the opening S, thereby sliding the fixing member 130 to the cover plate 110. It is fitted into the hole (111) and the hole 121 of the fixing bracket 120 to be fixed by the nut 132, assembled, and installed in the opening (S) so as not to move.

And, when installing the different size of the opening (S), loosen the nut 132 a little, move the fixing member 130 along the sliding long hole 111 to fix simply to the size of the opening.
