Description

Opening shielding frame for interlayer slab {Safety device for inter-layer slab}

The present invention relates to a safety structure installed to prevent a worker from falling when constructing a high-rise building such as an apartment or building, and more particularly, it can be conveniently installed in correspondence with the width of an opening formed in an interfloor slab. It relates to an opening shielding frame for interlayer slabs.

In general, during the pouring of concrete forming the foundation of a high-rise building, openings for installation of cables, conduit pipes, and various pipes are formed in slabs according to design specifications, and materials necessary for construction are also transported through this space.

That is, the opening is not only kept open toward the lower floor, like the installation area of the balcony, but also has a generally rectangular structure, and has a separate safety net or a separate safety net to block the access of field workers to places located high from the ground. If a blocking facility is not installed, a safety accident may occur in which the worker falls through the opening.

To prevent such safety accidents, safety nets must be temporarily installed in the openings formed in the interfloor slabs, and then all must be removed upon completion of the construction work, so safety accidents must be effectively prevented, as well as easy installation or dismantling work, and cost. It is necessary to manufacture it in a structure that can reduce the value.

However, the size of the construction site and the specifications of the openings installed in the building are different, so safety devices are installed according to the corresponding area, so they cannot be reused at other sites, and the width of the railing device cannot be adjusted directly at the construction site. Since it must be manufactured and installed, the work process is lengthened and the installation cost is increased.

With regard to the fall prevention of such an opening, for example, the technology disclosed in Korean Patent No. 0091182 is a flow frame by a rack of a flow frame that meshes with the pinion of the fixing frame by configuring the handrail with an "E"-shaped flow frame and a fixed frame. It is configured to firmly support the opening while moving in the left and right direction from the fixing frame, but there is a problem that the operator cannot use it conveniently due to the complicated structure.

In addition, in the case of Registered Patent No. 11519197, a lifting hook is mounted in the center of the upper surface of the center panel and at the same time, as the scaffolding panels are connected by hinges, the wires of the tower crane are hooked to lift the center panel so that the scaffolding panels face each other and fall. It was designed to prevent the problem, but these facilities also have a disadvantage that it is difficult to install the fall net.

Registered Patent No. 0091182 (registered on November 3, 1995)-A protective device for preventing fall of an opening on a wall. Registered Patent No. 1244903 (registered on March 11, 2013)-A protective device for preventing fall of an opening. Registered Patent No. 1519197 (registered on May 4, 2015)-Elevator opening fall prevention net.

The present invention is to solve the conventional problems as described above, and an object of the present invention is to provide an opening shielding frame for interfloor slabs that can be easily adjusted corresponding to the width of an opening formed in a concrete slab during construction of a high-rise building. .

The present invention for achieving this object is a first vertical body that is spaced apart in a horizontal direction so that the first and second horizontal pipes are mounted in one direction, respectively, and the first and second vertical frames so that the distance can be adjusted with respect to the vertical frame body. A second vertical frame body having first and second auxiliary pipes assembled into a horizontal pipe, a horizontal frame body having third and fourth auxiliary pipes respectively assembled into the vertical frame body, and the first to fourth auxiliary pipes It consists of a fastening bolt mounted to enable the length adjustment of the body, and a locking piece fixedly installed at each corner of the horizontal frame body including the vertical frame body.

In addition, a display hole is formed on one side of the flat portion of the vertical frame body and the horizontal frame body, so that a worker can visually check the binding state of the auxiliary pipes.

In the present invention, due to the above-described features, it is possible to adjust the length in the horizontal direction by the first and second vertical frame bodies as well as the length in the vertical direction by the horizontal frame body. It can be utilized regardless of the width of openings of various sizes formed in the slab.

In addition, since the openings can be shielded only by placing them on the openings while the length of each frame is adjusted and attaching a wire mesh or plywood, it has the advantage of very simple installation and dismantling.

First, as a preferred example to which the present invention is applied, the technology disclosed in Patent No. 1179440 will be described in detail, and after deriving the problems according to the present invention, the configuration and effects of the present invention will be described later.

As shown in the accompanying Figures 1 to 4, in this protective device, the first protective frame 10 and the second protective frame 20 are connected by a hinge 30, and these first and second protective frames A gap (S) is formed between (10, 20).

In addition, when the vertical portion 43 and the pressing member 45 of the fixing means 40 formed in a "T" shape are inserted into the gap S and tighten the bolt 48 of the fixing means 40, the fixing means 40 The horizontal portion 42 of the first and second protective frames 10 and 20 are pressed against the first and second protective frames 10 and 20, and the pressing member 45 of the fixing means 40 is the peripheral portion 51 of the opening 50 (see FIG. 3). 4), the first and second protective frames 10 and 20 are fixed around the opening 50, thereby blocking the opening 50.

In the first and second protective frames 10 and 20, a reinforcing material is mounted in the middle of a rectangular frame and a wire mesh is mounted on the frame. The hinge 30 is manufactured in a conventional structure that is folded and unfolded.

1 and 2, the fixing means 40 is a pressing member 45 is fitted to the vertical portion 43 of the T-shaped member 41, the pressing member 45 is the movable portion 46 and the movable portion A bolt 48, which is composed of a locking portion 47 attached to the lower end and fitted in the center of the horizontal portion 42 of the T-shaped member 41, is fastened to the upper fastening portion 46a of the movable portion 46.

When the vertical portion 43 of the T-shaped member 41 and the movable portion 46 of the pressing member 45 are formed of a square pipe and tighten the bolt 48, the movable portion 46 of the pressing member 45 is formed of a T-shaped member ( As it is inserted into the vertical portion 43 of 41), the locking portion 47 of the pressing member 45 is caught in the peripheral portion 51 (see FIG. 4) of the opening.

The protective device for preventing fall of the opening configured as described above, as shown in Figs. 3 and 4, the opening 50 in the unfolded state of the first protective frame 10 and the second protective frame 20; slab opening or wall surface The first protective frame 10 and the second protective frame 20 are in close contact with each other around the periphery of the opening), and then the vertical portion 42 and the pressing member 45 of the fixing means 40 are connected with a gap (S) therebetween. Install.

Subsequently, when the bolt 48 is tightened while the horizontal portion 42 of the fixing means 40 is in close contact with the first protective frame 10 and the second protective frame 20, the horizontal portion of the fixing means 40 ( 42) is pressed against the frames of the first and second protective frames 10 and 20.

Accordingly, as the movable part 46 of the pressing member 45 is inserted into the vertical part 43, the locking part 47 of the pressing member 45 is compressed to the circumferential part 51 of the opening 50, and the first The protective frame 10 and the second protective frame 20 are fixed around the opening 50 to block the opening 50.

In addition, when the bolt 48 is loosened, the fixing means 40 can be easily separated from the first protective frame 10 and the second protective frame 20 and thus can be easily removed from the opening 50.

However, in the prior art as described above, in a state in which the first and second protective frames are first installed in the opening, the horizontal and vertical parts constituting the fixing means must undergo a separate operation of assembling between the gaps. There is a problem that the operation itself is very cumbersome because the fastening operation must be performed by using.

Moreover, since it cannot respond to the width of the opening, it is practically impossible to reuse, and there is an unreasonable point that must be manufactured individually according to design specifications.

On the other hand, the accompanying Figures 5 to 8 are views for explaining the opening shielding frame for an interlayer slab according to the present invention.

As shown in these drawings, the present invention relates to the first and second vertical frame bodies 50A and 50B made of each pipe, the horizontal frame body 60 assembled to the vertical frame bodies 50A and 50B, and Consists of a fastening bolt 65 and a locking piece 66 for binding in a state where each frame body is adjusted to an appropriate width.

Accordingly, it is possible to adjust the length in the horizontal direction by simply pulling out the second vertical frame 50B based on the first vertical frame 50A.

In addition, the horizontal frame body 60 is equipped with third and fourth auxiliary pipes 61a and 61b that are respectively assembled into the hollow portions of the first and second vertical frame bodies 50A and 50B, so that each vertical frame body 50A, It is possible to adjust the length in the vertical direction simply by pulling out the horizontal frame body 60 from 50B).

Therefore, the width adjustment by each of the vertical frame bodies 50A and 50B and the horizontal frame body 60 can be conveniently made according to the width of the opening h formed in the concrete slab S.

In addition, display holes 62 are respectively formed on one side of the flat portion of the vertical frame bodies 50A and 50B and the horizontal frame body 60 so that the bonding state of the auxiliary pipes can be checked. That is, when the first and second auxiliary pipes 52a and 52b of the second vertical frame 50B are to be removed from the first and second horizontal pipes 51a and 51b of the first vertical frame body 50A, the marking hole It is something that the operator can check directly so as not to pass (62).

Likewise in the case of the horizontal frame body 60, the operator can visually check the display hole 62 when attempting to properly remove the third and fourth auxiliary pipes 61a and 61b from the vertical frame bodies 50A and 50B. I can.

In this way, by adjusting the length of the first to fourth auxiliary pipes (52a, 52b, 61a, 61b), use a tool in a state in which the widths of the vertical frame bodies 50A, 50B and the horizontal frame body 60 are determined. Thus, by properly tightening the fastening bolt 65, it is possible to secure a fixing force.

In addition, in the case of the locking piece 66, as it is mounted on each corner of the horizontal frame body 60, including the first and second vertical frame bodies 50A and 50B, it can be easily mounted and fixed on the opening h. In this state, a plate-shaped body 70 such as a wire mesh or plywood can be mounted to close the opening h.

As described above, according to the opening shielding frame for an interlayer slab according to the present invention, it is possible to adjust the length in the horizontal direction by the first and second vertical frame bodies as well as the length in the vertical direction by the horizontal frame body. When constructing a building, it can be used regardless of the width of the openings of various sizes formed in the concrete slab.
