Description

Scaffold board for gang form and manufacturing process of the same}

TECHNICAL FIELD The present invention relates to a work platform for a gangform and a method for manufacturing the same, and a work platform for a gangform and a method for manufacturing the same, which are configured to have a function of drainage and a slip prevention function while having a very simple manufacturing process and structure.

Gang platform working scaffold is installed in the frame of gang form and used for work and passage in high place. Such a gangform working scaffold is fixed to a scaffold frame layered with a plurality of grids, and each scaffold has a structure in which a rod, a section steel, or the like is welded to its lower surface for its rigidity. And the scaffold is formed with a discharge hole of a predetermined size.

When the concrete is poured using the formwork, such as building the building, a plurality of discharge holes are formed in order to prevent the collapse of the formwork to prevent the collapse of the scaffold under the load of the concrete. In other words, it is to prevent the collapse of the flowing concrete to prevent the load from acting on the scaffold. In addition, the discharge hole also serves as a drain for draining down when water falls on the upper surface of the scaffold.

In addition, a plurality of anti-slip projections are formed on the upper surface of the gangform work scaffold to prevent the operator from slipping.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the conventional gangform scaffolding.

1 is a perspective view of a conventional gangform working scaffold, FIG. 2 is a sectional view of a conventional gangform working scaffold, and FIG. 3 is a plan view of a conventional gangform working scaffold.

As shown in FIGS. 1 to 3, in the conventional gangform working scaffold, a plurality of through holes 1a are formed at regular intervals, and ribs 3 having a toothed protrusion 4 formed on the edge thereof are formed. It is supposed to act as a force.

That is, the rainwater and the like are easily discharged by the drain hole 2a formed between the through hole 1a and the through hole 1a, and concrete that overflows due to breakage of the formwork is easily discharged. Therefore, the work scaffold 100 is prevented from being collapsed due to the load due to the accumulation of concrete.

In the present invention, the through hole 1a is widely formed, but ribs 3 are formed at the edges of the through hole 1a so that the rib 3 acts as a force so that deformation does not occur even at a high load. In addition, the end of the rib (3) is provided with a sawtooth-shaped projection (4) it is possible to prevent the operator from slipping on the work footing (100).

In addition, the working scaffold 100 should have a structure that prevents slippage by water during rain and work, as well as drainage by the through hole (1a), and has a separate drain (2a). That is, a plurality of drain holes 2a are formed between the through holes 1a to provide a safety structure that prevents slipping together with the toothed protrusion 4. The rib 3 facing downward is also formed in the above-mentioned drain port 2a.

In the long space portion in which the drain hole 2a is formed in a line between the through hole 1a and one side of the through hole 1a, a long arc-shaped rib having an arc-shaped cross section as shown in FIGS. 5) is formed, and it is a concave shape especially. Therefore, it acts as a drainage of water during rainy weather or work, and leads to the water draining well to the drain (2a).

However, in the conventional gangform working scaffold configured as described above, ribs 3 formed at the edges of each through hole 1a must be formed separately, and the toothed projections 4 are formed at each end of each rib 3. Since it must be formed, the production is very difficult, there is a problem that the productivity is extremely low and accordingly the manufacturing cost is very high.

In addition, since the arc-shaped ribs 5 must be formed around the drain hole 2a for smooth drainage, this also has a significant effect on the decrease in productivity and the increase in manufacturing cost.

In addition, the rib 3 formed in the conventional gangform working scaffold configured as described above is only for reinforcing the strength of the site where the toothed projection 4 is formed, and it is possible to prevent the warping or twisting of the entire gangform working scaffold. The disadvantage is that it cannot be reinforced.

The present invention has been proposed to solve the above problems, it is possible to more quickly and effectively discharge the water or other fluids falling to the upper surface, to prevent the slip of the operator, the manufacturing process and structure is very simple, productivity It is an object of the present invention to provide a work platform for gang foam and a method of manufacturing the same that can improve and reduce manufacturing costs.

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

4 and 5 are a plan view and a cross-sectional view of the gangform working scaffold according to the present invention, Figures 6 and 7 are perspective views sequentially showing the manufacturing process of the gangform working scaffold according to the present invention.

The gangform working scaffold according to the present invention includes a plate 100 having a length on one side, and two or more anti-slip protrusions 200 formed on the upper surface of the plate 100. The non-slip protrusion 200 has a thickness in the width direction of the plate 100 and two or more anti-slip protrusions protruding upward from the upper surface of the plate 100 to have a width in the longitudinal direction of the plate 100 ( Consisting of 210, two or more non-slip projections 210 included in one non-slip protrusion 200 is arranged in the width direction, that is, spaced apart in the longitudinal direction of the plate 100. In addition, a drain hole 300 is formed between two neighboring non-slip projections 210.

At this time, the upper surface of the plate 100 between two adjacent non-slip protrusion rows 200 is formed to be inclined to be higher than the upper surface of the plate 100 at the point where the drain hole 300 is formed, concrete or water having fluidity When the silver falls to the upper surface of the plate 100 flows down the inclined surface of the plate 100 toward the drain hole 300 is discharged to the lower side of the plate 100. That is, the gangform working scaffold according to the present invention has an advantage that the concrete or water having fluidity can be easily discharged to the lower side even if it falls anywhere among the upper surfaces of the plate 100.

Since the plate 100 is a member directly receiving the weight of the worker, when the weight of the worker is applied between a relatively upwardly protruding portion, that is, the non-slip protrusion column 200, the non-slip protrusion column 200 is below Deflection can cause the slope to disappear. As such, when the inclined surface is removed from the upper surface of the plate 100, the flowable concrete and water dropped to the upper surface of the plate 100 can not easily flow to the drain hole 300 side, the discharge effect of the flowable concrete and water is significantly reduced. Problems arise.

Therefore, the gangform working scaffold according to the present invention further includes a support portion 400 extending downward from the bottom surface of the plate 100 at a point of relatively high height, that is, between two adjacent non-slip protrusion rows 200. It is configured to. When the support unit 400 is provided as described above, even if the weight of the worker is applied between the non-slip protrusion rows 200, the phenomenon of falling down between the non-slip protrusion rows 200 is prevented, thereby discharging the flowable concrete and water. There is an advantage that the degradation can be prevented.

In addition, the gangform working scaffold according to the present invention, so that the slope of the inclined surface can be increased while minimizing the height difference between the highest point and the lowest point of the plate 100, the anti-slip projection 200 and the support 400 is the plate It is preferable that they are formed alternately in the width direction of the (100). That is, the plate 100 is preferably formed in a lateral cross section in a zigzag shape or a wave shape. As such, when the transverse cross section of the plate 100 is zigzag-shaped or wavy, the inclination of the inclined surface may be increased while minimizing the height difference between the highest point and the lowest point of the plate 100, and the plate 100 as a whole. It also has the advantage of being able to reinforce the flexural strength and torsional strength.

The working platform for the gangform according to the present invention, the anti-slip projection 200 and the support 400 is not manufactured separately from the plate 100, the plate 100 and the non-slip projection 200 and the support ( Another feature is that 400 is integrally manufactured through one extrusion process in the longitudinal direction of the plate 100. At this time, the non-slip protrusion 200 is composed of a non-slip protrusion 210 spaced apart in the longitudinal direction of the plate 100, the anti-slip protrusion 200 is shown in this embodiment only by the extrusion process It is not formed in a shape, it is formed through a punching process for forming the drain hole (300).

That is, the gangform working scaffold according to the present invention, as shown in Figure 6, the plate 100 having a length to one side, and the upper surface of the plate 100 to have a width in the longitudinal direction of the plate 100 An extrusion step of manufacturing the protrusion 200 ′ provided by one extrusion method; As shown in FIG. 7, two or more non-slip protrusions 210 are arranged to be spaced apart from each other in the longitudinal direction of the plate 100, as shown in FIG. 7. It is formed through the punching step 200 is formed, the punching step to form a drain hole 300 between the non-slip projections 210.

As shown in this embodiment, when the support part 400 is provided on the bottom of the plate 100, the extrusion step includes the plate 100, the protrusion part 200 ′, and the support part 400 by one extrusion method. Can be configured to produce. Additionally, the extruding step may alternately form the protrusion 200 ′ and the support part 400 in the width direction of the plate 100, and form a zigzag or wavy shape in a lateral cross section of the plate 100. It is preferable that the upper surface of the plate 100 is formed so that the portion provided with the support portion 400 is formed higher than the portion provided with the anti-slip projection (200). Since the purpose and effect of forming the plate 100, the protrusion 200 ′, and the support 400 in the above structure have been mentioned above, a detailed description thereof will be omitted.

In this case, if the drain hole 300 is not formed on the protrusion 200 ′, the protrusion 200 ′ remains as shown in FIG. 6, and thus the shape of the protrusion 200 ′ is shown in FIG. 6. When it is maintained in the shape, the protrusion 200 ′ prevents the worker's foot from sliding in the width direction of the plate 100, but prevents the worker's foot from sliding in the longitudinal direction of the plate 100. There will be no. That is, as illustrated in FIG. 7, the drain hole 300 is formed on the protrusion 200 ′ so that the protrusion 200 ′ is provided with a plurality of non-slip protrusions 210 arranged in the longitudinal direction of the plate 100. If deformed, since the worker's foot is caught on the left and right ends of the non-slip protrusion 210 at the time when the worker's foot starts to slide in the longitudinal direction of the plate 100, slipping in the longitudinal direction of the plate 100 does not occur. The advantage is that it does not.

In addition, the greater the number of non-slip protrusions 210 formed as one protrusion 200 ', the greater the anti-slip effect in the longitudinal direction of the plate 100, so that the punching step includes a portion where one protrusion 200' is formed. It is preferable to be configured to puncture two or more times along the width direction of the protrusion (200 ').

In addition, the gangform working scaffold according to the present invention, the plate 100 and the anti-slip projection 210 and the support portion 400 by only two processes (that is, extrusion process and punching process) without the need to separately manufacture each component. And the production of the drain hole 300 is completed, the manufacturing process is very simple, there is an advantage that the productivity is improved and the manufacturing cost is very low.

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment, Comprising: It should be interpreted by the attached Claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
