Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction scaffold for preventing a safety accident using a safety stopper,

The present invention relates to a construction scaffolding device.

A scaffold is used to construct the building. Conventional scaffolds use a circular frame to set up the skeleton, and a clamp to hold the circular frame.

However, various problems have been pointed out in the conventional scaffold. First, the circular frame is heavy and difficult to handle because it is made of steel. In addition, since steel is corroded, durability was also problematic. In addition, even if the clamp for fixing the circular frame is slightly loosened, the weight of the circular frame collapses the scaffold, resulting in a safety accident.

Accordingly, the inventor of the present invention has studied for a long time to solve such a problem, developed through trial and error, and finally completed the present invention.

Provided is a method of constructing a construction scaffolding device for preventing a safety accident by using a safety stopper.

According to the present invention, there can be provided a construction scraper for preventing a safety accident using a safety stopper and a construction method thereof.

The vertical scaffold and the horizontal scaffold of the present invention are made of aluminum and are light and high in strength. The structure of the quadrangle and the arrangement of the internal skeleton and the external skeleton are structurally resistant to bending, so that collapse of the scaffold can be prevented.

Since the wedge fastened to both ends of the horizontal scaffold of the present invention is inserted into the fastening groove of the vertical scaffold, the wedge still hangs on the vertical scaffold even when the wedge is detached from the flange. Therefore, even if the horizontal scaffold is pulled out of the flange, the horizontal scaffold does not deviate from the vertical scaffold unless it is inclined at a predetermined slope, so that a safety accident can be prevented.

The safety stopper of the present invention performs a lock mode with a horizontal scaffold and a structure that surrounds the flange from the outside, thereby preventing the horizontal scaffold from deviating from the vertical scaffold. Therefore, safety accidents can be prevented.

Since the safety hook of the present invention is a structure that does not come off due to vibration or a small force, the safety stopper is prevented from being released from the lock mode, thereby further preventing a safety accident. On the other hand, since the safety hook is easily separated when an appropriate force is applied to the rear, the disassembling operation is facilitated.

Since the wedge of the present invention has a structure in which the first protrusion and the second protrusion are fastened to the flange and the vertical scaffold, the horizontal scaffold can be more firmly fixed. Also, since the safety stopper in the lock mode wraps the horizontal scaffold and the flange from the outside, the horizontal scaffold can be further prevented from escaping and is safe.

Further, since the wedge of the present invention includes the first protrusion and the second protrusion, the wedge of the present invention can cope with the deformation force applied to the horizontal scaffold in the lateral direction. That is, even if there is a deformation force applied in the lateral direction, the scraper device can be more firmly held.

Meanwhile, the present invention has an effect of solving the problem of a ring type safety foot using a plate-type fastening plate to solve the problem that the conventional ring type safety foot is difficult to support a high load. In addition, at least one safety footrest supporting member that crosses the lower end of the safety footrest is installed, thereby supporting the high load and preventing the footrest from being shaken.

On the other hand, even if the effects are not explicitly mentioned here, the effect described in the following specification, which is expected by the technical features of the present invention, and its potential effects are treated as described in the specification of the present invention.

In the present specification, the scaffold for building can be used not only for temporary scaffolds used during construction but also for making skeletons of a frame or a building of a building by its unique stability. Therefore, in the following, the meaning of scaffolding and scaffolding for construction is interpreted to include not only temporary scaffolding but also the use of making a skeleton of a building frame or object. For example, a scaffold for building using a square frame can be interpreted as a frame structure for a building using a square frame.

The wedge 500 is fastened to both ends of the horizontal scaffold 300 so that the horizontal scaffold 300 is coupled to the vertical scaffold 200 and the flange 400. When the horizontal scaffold 300 is coupled to the flange 400, the safety scaffold 600 is slid in the vertical scaffold direction and is guided by the horizontal scaffold 300 and the flange 400, Thereby locking the horizontal scaffold 300 away from the flange 400. In this embodiment, The safety footplate 700 is mounted on and coupled to the horizontal scaffold 300 to support the operator. The safety foot support member 800 includes a wedge coupled to both ends of the horizontal scaffold 300. The safety footrest supporting member 800 is mounted on the horizontal scaffold 300 at the lower center of the safety footplate 700 to more firmly support the load of the safety footplate 700. [ The safety footrest 700 of the present invention has the effect of solving the problem of the ring-type safety footrest by using a plate-like fastening plate to solve the problem that the safety footrest of the conventional ring type is difficult to support a high load. In addition, at least one safety footrest supporting member 800 across the lower end of the safety footrest is installed to support the high load and prevent the footrest from being shaken.

The support portion 330 extends from the edge of the inner skeleton to connect and support the inner skeleton 310 and the outer skeleton 320.

The fastening holes 340 are formed at the center of both long sides of the outer skeleton 320. The diameter of the fastening hole 340 is shorter than the long side of the inner skeleton.

The fastening groove 350 is formed between the fastening hole 340 and the inner skeleton 310 and is a rectangular hollow space surrounded by the long sides of the outer skeleton 320, the support portion 330, and the inner skeleton 310 .

The anti-slip grooves 360 are formed in the short sides of the outer skeleton by concave grooves to prevent slippage.

The foot fastening groove 370 is formed in one of the short sides of the external skeleton and is an empty space twice as long as the thickness of the joint portion of the safety foot.

4 is a view showing a preferred embodiment of the flange of the present invention.

4, the flange 400 includes a base 410, an inner protrusion 420, a wing portion 430, and a wing hollow 440.

The base 410 has a square shape with a predetermined thickness. A square inner hollow 405 having a size corresponding to the diameter of the outer skeleton of the vertical scaffold is formed at the center of the base so that a vertical scaffold can be inserted. The inner protrusion 420 is a protrusion recessed from the inner surface of the base 410 toward the wing hollow 440. The first protrusion of the wedge can be inserted into the space formed by the inner protrusion 420 and the space formed by the fastening groove of the vertical scaffold.

The wing portion 430 is formed extending from each side of the base 410. At the center of the wing portion 430, a rectangular wing hollow 440 into which the second protrusion of the wedge is inserted is formed.

5 is a view showing a preferred embodiment of the safety stopper of the present invention.

5, the safety stopper 600 includes a main body 610, a safety hook fastening portion 620, a horizontal scaffold fastening protrusion 630, a horizontal scaffold fastening space 640, a flange fastening space 650, And may include a security catch 670.

The main body 610 is a rectangular frame, and a rectangular inner hollow having a size corresponding to the diameter of the outer framework of the horizontal scaffold is formed so that the horizontal scaffold can be inserted.

The safety hook fastening portion 620 is formed on the upper side of the main body and has a thickness smaller than the thickness of the upper side of the main body so that the safety hook 670 can be fastened.

The horizontal scaffold fastening protrusion 630 is a protrusion formed by protruding inwardly from the both sides of the main body and inserted into the fastening groove of the horizontal scaffold.

The inner hollow of the safety stopper is formed with a horizontal scaffold engagement space 640 into which a horizontal scaffold is inserted and a flange engagement space 650 into which the flange is inserted. Since the horizontal scaffold engagement space 640 and the flange engagement space 650 are spaces enclosed by the main body 610, the safety stopper can be fixed in a form that surrounds the horizontal scaffold and the flange when the safety stopper is in the lock mode.

The safety hook 670 is fastened to the safety hook fastening portion so that the safety stopper is not released in a direction away from the vertical scaffold when the safety stopper is in the locking mode.

The safety hook 670 includes a horizontal plate 671 extending in the horizontal direction, a front end vertical plate 672 extending upward from the front end of the horizontal plate, a first bent portion 674 extending from the top end to the rear end of the front end vertical plate , A rear-end straight plate 675 extending upward from the rear end of the horizontal plate, a second bent portion 677 extending from the upper end of the rear-end straight plate to the front end, 678, and a rear foot plate 680 extending downward from the rear end of the horizontal plate.

The first bent portion 674 and the second bent portion 677 of the safety hook 670 are not connected to each other but are spaced apart from each other by a predetermined length and the safety hook engagement portion 620 of the safety stopper is inserted through the gap, The safety hook fastening portion can move with a predetermined clearance in the up-and-down front-back direction in the inner space formed by the horizontal plate, the front-end vertical plate, the first bent portion, the rear-end straight plate, and the second bent portion of the safety hook 670 Lt; / RTI >

In the lock mode, the shear footrest of the safety hook is placed over the step formed between the wedge and the horizontal scaffold to prevent the safety stopper from deviating in a direction away from the vertical scaffold.

The front end vertical inner surface 673 of the front end vertical plate 672 is inclined at a predetermined angle with respect to the vertical upper side of the horizontal plate 671 so as to be forward, The footrest is automatically spread over the step formed between the wedge and the horizontal scaffold to prevent the safety stopper from being released in a direction away from the vertical scaffold.

The rear end vertical inner surface 676, which is the inner surface of the rear end straight plate 675, is formed to be inclined at a predetermined angle so as to face rearward with respect to the vertical direction of the horizontal plate 671 so that the safety stopper is separated from the vertical scaffold So that the safety stopper is easily moved backward by transmitting a force for lifting the safety hook upward.

This will be described in more detail in Fig. 7 and Fig.

6 is a view showing a preferred embodiment of the wedge of the present invention. 6 (a) shows a wedge which is coupled to both ends of a horizontal scaffold to be fastened to a vertical scaffold and a flange, and Fig. 6 (b) shows a wedge which is coupled to both ends of a horizontal scaffold Respectively. Hereinafter, the wedge shown in FIG. 6 (a) will be described.

6, the wedge 500 includes a body portion 510, an engagement pin 520, a first protrusion 530, and a second protrusion 540. As shown in FIG.

The body 510 is a triangular plate having a predetermined thickness. The oblique surface formed on the upper portion of the front portion of the body portion 510 helps to prevent interference when the horizontal scaffold is tightened between the vertical scaffolds. That is, if this portion is projected, it becomes difficult to fasten the horizontal scaffold to the vertical scaffold.

The coupling pins 520 extend from the rear end of the body 510 and may be formed as a pair. The engaging pin 520 is inserted and fixed in the horizontal scaffold 300.

The first protrusion 530 extends from the lower end of the body 510. The first protrusion 530 is inserted into the space formed by the engagement groove of the vertical scaffold and the inner protrusion of the flange.

The second protrusion 540 extends from the lower end of the body 510 and is disposed at the rear end of the first protrusion. The second projection 540 is inserted into the hollow of the flange.

By arranging the two protrusions like the first protrusion 530 and the second protrusion 540, the horizontal scaffold can be more firmly fixed in the lock mode.

FIG. 7 is a view for explaining the assembling process of the safety stopper according to the present invention.

5 and 7, when the safety stopper 600 is pushed backward as shown in (a), the front end scaffold 678 and the rear end scaffold 680 of the safety spider 670 are positioned on the upper surface of the horizontal scaffold And the lower surface of the safety hook fastening portion 620 is in contact with the upper surface of the horizontal plate 671.

when the safety stopper 600 is pushed in the direction of the vertical scaffold 200 as shown in (b), the safety hook moves in the form of (a) to (b). That is, when the safety stopper 600 is pushed in the vertical scaffold direction, the front end of the safety hook fastening portion 620 touches the front end vertical inner surface 673. At this time, the safety hook 670 receives a force in the counterclockwise direction F1 by the inclined direction of the front-end vertical inner surface 673. That is, the front end of the safety hook 670 is urged counterclockwise.

when the safety stopper 600 is in the locking mode as shown in FIG. 6C, the front footrest 678 is struck by the step formed between the horizontal scaffold 300 and the wedge 500. FIG. There are two forces that cause the front end of the safety hook 670 to fall from the locked mode into the step. The first is that the horizontal scaffold supporting the shear pedestal 678 has disappeared, so it falls down by gravity. The second reason is that the safety hook 670 receives the force in the counterclockwise direction F2 by the inclination direction of the front vertical inner surface 673. When the lock mode is established by the two forces, the front footrest of the safety hook 670 is moved over the step formed between the wedge and the horizontal scaffold to prevent the safety stopper from deviating from the vertical scaffold.

8 is a view for explaining a process of releasing the engagement of the safety stopper according to the present invention.

5 and 8, when the safety stopper 600 is pulled backward as shown in (d) to release the lock mode, the rear end of the safety hook fastening portion 620 contacts the rear end vertical inner surface 676 . Since the rear vertical inner surface 676 is inclined rearwardly, the safety hook 670 receives a force in the clockwise direction F2. Therefore, the shear stool 678 helps to easily pass the step. When the safety hook 670 is released, the front footrest 678 comes to the top of the horizontal scaffold again. In order to facilitate this, a foot plate protrusion 679 may be formed between the rear end of the front end foot plate 678 and the horizontal plate 671. The pedal protrusions 679 serve as predetermined stairs so that the front pedestal 678 can be raised more easily to the upper surface of the horizontal scaffold.

Fig. 9 shows a preferred embodiment of the safety footrest according to the present invention.

9, the safety footrest 700 includes a footrest portion 710 and a fastening plate 720. As shown in FIG.

The pedestal portion 710 has a perforated hole for preventing slipping on a rectangular plate. The fastening plate 720 is fastened to both ends of the foot plate 710 to fix the foot plate to the horizontal scaffold. The fastening plate 720 includes a main body 721 having a "C" shape and a coupling portion 723 extending downward from a lower end of the main body. Since the fastening plate 720 has a long elongated plate shape, the fastening plate 720 can support a higher load than the annular safety footrest.

The horizontal scaffold 300 disposed in the Y-axis direction is disposed so that the footrest coupling groove 370 faces upward. The two footrest engaging portions 723 of the two adjacent footrest engaging portions are fitted together in one footrest engaging groove 370. Since the fastening plate 720 has a long elongated plate shape, the fastening plate 720 can support a higher load than the annular safety footrest. In addition, at least one safety footrest supporting member that crosses the lower end of the safety footrest is installed, thereby supporting the high load and preventing the footrest from being shaken.

[Safety sensor]

In another embodiment, the scraping device of the present invention further comprises a safety sensor for measuring whether the lock mode of the safety stopper has been released.

In a preferred embodiment, the safety sensor is installed in at least one of a safety stopper, a vertical scaffold, a flange, or a horizontal scaffold to measure the difference between a reference position in which a safety stopper is to be present in a lock mode and a current position in which a present safety stopper is present . For example, if a safety sensor is installed on a vertical scaffold, measure the reference position where the safety stopper should be in the lock mode. If the present position of the safety stopper is far away, it can be seen that the safety stopper has been removed.

In another embodiment, the safety sensor may comprise a first sensor mounted on the safety stopper and a second sensor mounted on at least one of a vertical scaffold, a flange, or a horizontal scaffold. The first sensor and the second sensor can measure the distance between each other. The first sensor and the second sensor may be a set of sensors that receive and transmit infrared rays and the like. In either case, the first sensor and the second sensor can check whether the safety stopper has been released from the lock mode.

In another embodiment, the safety sensor may be a distance sensor. In this case, the safety sensor can be installed on the safety stopper. The safety sensor installed on the safety stopper can measure the distance from the vertical scaffold. On the other hand, if the safety sensor is mounted on a vertical scaffold, it is of course possible to measure the distance between the safety sensor and the safety stopper.

In the meantime, the safety sensor of the present invention can implement the Internet (IoT) function. Security Sensor Objects With the Internet function, each safety sensor can transmit measured data to the safety sensor monitoring server without connecting multiple safety sensors to the wired network.

[Safety Sensor Monitoring Server]

The safety sensor can be installed on a plurality of safety stoppers. That is, it may be installed for each of a plurality of safety stoppers fastened to the connecting portion between the vertical scaffold and the horizontal scaffold. A plurality of safety sensors can transmit observations to one monitoring server. The monitoring server can continuously monitor the values of the observed safety sensors and monitor the safety of the scaffolds installed at a specific site. For example, if there is a risk factor in the value of the safety measure installed on the horizontal scaffold that corresponds to the fifth and fifth layers of the vertical scaffold placed in the third row, inform the field worker and check the safety stopper and horizontal scaffolding status Safety accidents can be prevented in advance.

[Safety stopper color]

In a preferred embodiment, a first color may be applied to the safety stopper and a second color applied to the end of the horizontal scaffold. This allows only the first color of the safety stopper to be visible in the lock mode and the second color of the end of the horizontal scaffold to be exposed when the lock mode is released. This makes it possible to diagnose whether the safety stopper is in the lock mode or released from the lock mode and is in a dangerous state even if it is observed from afar.

In another embodiment, a predetermined color (e.g., red) may be applied to the end of the horizontal scaffold. The color may not be applied to the safety stopper. In this case, if the safety stopper is in the locked state, the color applied to the end of the horizontal scaffold can not be seen from the outside, so that it can be easily seen that the lock mode is maintained. On the other hand, when the lock mode is released, the color applied to the end of the horizontal scaffold is exposed, so that the dangerous condition can be easily diagnosed from the outside.

[Construction method of architectural scaffold]

A construction method of a construction scaffolding apparatus constructed using the scaffolding apparatus of the present invention will be described.

First, vertical scaffolds provided with flanges for supporting horizontal scaffolds are arranged at predetermined intervals.

Next, a horizontal scaffold secured with the safety stopper movably is fastened between a plurality of vertical scaffolds.

At this time, the step of installing the horizontal scaffold may be the following three steps.

First, one end of the horizontal scaffold is tilted and inserted between the plurality of vertical scaffolds, so that a wedge attached to both ends of the horizontal scaffold is inserted into the fastening hollow of the vertical scaffold (one end is tilted as shown in FIG.

Next, the wedge attached to both ends of the horizontal scaffold is inserted into the fastening hollow of the vertical scaffold, and the tilted horizontal scaffold is held horizontally.

Finally, the horizontally maintained horizontal scaffold is moved downward along the vertical scaffold so that the wedge is fastened to the flange.

When the horizontal scaffold is placed on the flange as described above, the safety stopper of the horizontal scaffolding fastened to the flange is slid in the direction of the vertical scaffold and fastened so that the horizontal scaffold is fixed so as not to be detached from the flange.

[Minimum escape height of horizontal scaffold]

When the horizontal scaffold of the present invention is installed between the vertical scaffolds, one end of the horizontal scaffold is tilted so that the wedge at both ends of the horizontal scaffold is fitted in the vertical scaffolding engagement grooves. Applying this principle to a dismantling or collapse accident, it can be seen that the horizontal scaffold does not deviate from the vertical scaffold unless one end of the horizontal scaffold goes above the minimum clearance height. This will be described in more detail with reference to FIG.

10 is a view for explaining the minimum removal height of the horizontal scaffold of the present invention.

As can be seen from FIG. 10, when one end of the horizontal scaffold is below the minimum removal height, the wedge at both ends of the horizontal scaffold still fits into the vertical scaffolding fastener. Therefore, in a situation where one end of the horizontal scaffold is less than or equal to the minimum clearance height (i.e., the horizontal scaffold is inclined at a certain angle or less), the horizontal scaffold does not deviate from the vertical scaffold. Therefore, the present invention is advantageous in that even if the safety stopper is released and the horizontal scaffold is separated from the flange, the one end of the horizontal scaffold is not collapsed unless the height exceeds the minimum separation height.

The scope of protection of the present invention is not limited to the description and the expression of the embodiments explicitly described in the foregoing. It is again to be understood that the present invention is not limited by the modifications or substitutions that are obvious to those skilled in the art.
