To achieve this, the tread for stairs using useless materials in grating comprises: a plurality of tread bars made of a bearing bar as a useless material in grating; and a tread main body which has one or more joints which are alternately inserted and fixated to the tread bars to make up the treads by alternately fixating the tread bars and the joints.

Description

{Foot board of stair using useless parts}

The present invention relates to a stair tread using a non-use material of grating having a large lattice structure to allow drainage, and more particularly, to a tread capable of using reclaimed materials remaining after use of raw materials of grating as a tread It is about the steps of a stair using the insoluble material of Gritting.

Generally, grating is a grid type pallet, which is used mainly in roads, drainage maintenance parts in buildings, and various facilities such as ships.

The grating is basically constructed to have a lattice structure consisting of a plurality of cross bars passing through the bearing bar in two axial directions intersecting a plurality of bay bars arranged in parallel in one axial direction so as to be drained.

The bearing bar and the crossbar are configured to allow water to be drained through the lattice puncture portion and to filter out foreign matter having a predetermined size or more, while a walker or a vehicle with a small wheel (trunk bag, inline skating bar, etc.) The wheels are being used so that they do not fall into the drains or get caught in the drains.

These gratings are manufactured and used in various ways depending on the application. Small gratings for inflow of rainwater into roads and larger gratings for ships are used in various sizes.

The above grating is cut into a designed shape, and a large amount of unused material of the remaining remnant is generated, which is treated as waste, and the material cost is greatly lost.

Such unused materials are difficult to recycle in industry, which is a cause of environmental pollution, and there is a problem that it is difficult to dispose of the insoluble materials by strengthening environmental regulations, promoting recycling, and narrowing the landfill.

In addition, since the ship structure is largely composed of 3 ~ 5 layers, grating type grating is required to recognize the following points of the passageways during the passage of cargoes and people, and a large amount of unused materials is generated due to high demand, A method was required.

Furthermore, in places where small size is installed, there is a need for a method of recycling unused materials.

It is preferable that the stepping bar 22 is formed in an "I" shape.

In addition, at least one or more insertion holes 24 may be arranged and the connection portion 40 may be inserted through the insertion hole 24 and fixed.

The insertion hole 24 is more preferably circular, but may be formed to have at least a triangle or a triangle at a user's choice.

In addition, it is preferable that at least one or more than one fixing hole 26 to which the fixing means 66 can be inserted and fixed is further provided on the step bar 22 at both ends of the tread body 20.

The connecting part 40 is provided with a connecting bar 42 having at least one intersecting groove 44 inserted through the step bar 22 and fixing the step bar 22 at a predetermined interval, And a fixing rod 48 fitted in the connecting bar to fix the connecting bar.

The connecting bars 42 are integrally formed in a straight shape and protrude from the guide protrusions 46 and intersecting grooves 44 are formed at predetermined intervals so that the step bars 22 are spaced apart from each other by a predetermined distance So as to be spaced apart and fixed.

The fixing rod 48 is preferably a cylindrical rod, but may be provided with at least three or more rods by the user's choice.

A guide groove 49 is provided in the longitudinal direction of the connecting bar 42 so as to correspond to the connecting bar 42 so that the connecting bar 42 is guided by the connecting bar 42, As shown in FIG.

In addition, a tread reinforcing portion 60 is provided at one or more ends of the tread main body 20 or at both ends thereof to fix at least one reinforcing bar 62 provided with a bearing bar, which is not used for grating, .

Most preferably, the reinforcing bar 62 is used for forming the tread body 20 and reused by utilizing the remaining step bar 22. [

Therefore, the reinforcement bar 62 is formed with an "I" character having the same shape as the step bar 22 and at least one or more than one fixing holes 64 for fixing the fixing means 66 are provided.

It is preferable that the fixing means 66 is provided with a known bolt or rivet.

It is preferable that the step bar 22, the reinforcing bar 42, and the connecting portion 40 of the tread 10 according to the present invention are made of a metal or a synthetic resin having high strength.

Further, it is more preferable that a non-slip member is applied to the upper portion of the lifting bar 22 or the reinforcing bar 42 to prevent slipping.

The coupling relationship and the operating relationship of the tread plate 10 according to the present invention will be described in detail with reference to the drawings.

First, the treads 22 corresponding to the required length are provided at predetermined intervals so as to be the tread 10.

At this time, at least one or at least one insertion hole 24 is provided in the stepped bar 22.

3 and 4, the connecting bar 42 of the connecting portion 40 is inserted through the insertion hole 24 of the stepping bar 22. [

At this time, the intersecting groove 44 provided in the connecting bar 42 is inserted into the insertion groove 24 provided in the step bar 22.

Therefore, the plurality of the dimming bars 22 are inserted into the intersecting grooves 44 of the connecting portion 40 so that the plurality of the dimming bars 22 are kept at a constant interval, Respectively.

The guide grooves 49 of the stationary bar 48 are coupled to the guide protrusions 46 provided on the connection bar 42 to guide the stationary rods 48, .

The fixing bar 48 has the same outer diameter as the inner diameter of the insertion hole 24 so that the connecting bar 42 is maintained in a fixed state so that the plurality of dimming bars 22 are cross- ) Are combined.

In addition, as shown in FIG. 4, the fixing position of the connecting bar 42 can be fixed regardless of the direction.

After the tread plate body 20 is formed as described above, the reinforcing bar 62 of the reinforcing portion 60 is connected to the one end of the tread plate body 20 at one end or both ends of the tread plate body 20, ) Is further positioned.

5 to 7, at least one or more than one reinforcing bars 62 are arranged by the user's choice, and the fixing means 66 of the reinforcing portion 60 is arranged at a distance And the fixing holes 26 and 64 provided in the reinforcing bar 62. [

At this time, the fixing means 66 is the same as the fixing method of the known bolts and rivets.

More preferably, when the tread main body 20 and the reinforcing portion 60 are fixed to each other by the fixing means 66, they are more firmly fixed by the adhesive.

The adhesive is preferably an epoxy adhesive having strong adhesive strength and excellent resistance to chemicals, heat resistance, and water resistance so as to prevent the tread plate from spreading due to a load, and it is preferable to use a known adhesive applicable to the field Adhesive may be used.

Of course, the adhesive can be used at the user's option even when the cross bars of the detaching bars and the connection portions are fixed.

In addition, it is more preferable that the slider is applied to the upper portion of the step bar and the reinforcing bar to prevent slipping of the user.

The tread plates mutually coupled as described above can reduce the waste of materials by reusing the remaining tread plates after cutting the dimmer bars forming the treads to further form the reinforcing portions.

Further, when the tread plate is formed in a small size or its mounting position has various shapes such as an edge or a shape thereof, the reinforcing portion can be formed into various shapes.

Further, the reinforcing portion can prevent breakage of the tread plate, and the broken reinforcing portion can be easily replaced.

In addition, it is easy to disassemble and assemble the tread plate so that anyone can easily apply it to the field, and it is easy to maintain and repair steel.

In addition, the tread reinforcement is assembled so as to be able to function as a buffer to compensate for the load load of the tread plate and the damage caused by the impact or shock when moving or contacting with other materials.
