Pasted. Also, apply a base coat for iron, apply a non-slip floor coating to the top surface of the lining plate using a spatula, etc., then use a roller brush to secure the surface roughness, and then remove the masking tape. Stopping flooring was constructed.

  However, this non-slip flooring paint flows a large amount between the masking tape and the top edge of the lining plate during the painting process, resulting in a high loss rate, and the non-slip flooring material is heavily consumed. There is.

  In addition, there is a problem that construction waste is generated due to wear of the masking tape, roller brush, and loss of paint on the non-slip flooring material, which increases construction time and cost. In addition, there is a problem in that work efficiency is reduced due to occurrence of processes such as masking removal and painting / removal work of the edge of the lining plate.

  In addition, conventionally, when a strain occurs due to a load on the lining plate or an external environment, or when a plurality of layers are stacked in the vertical direction, a coating layer of a non-slip flooring material applied to the upper surface by the load of the lining plate However, there is a problem that the upper surface of the lining plate is peeled off or damaged such as cracks. Therefore, the conventional lining board has a high defect rate, and there is a problem in that unnecessary repair work and maintenance costs are generated, resulting in a decrease in economy and productivity.

  Furthermore, with the conventional lining board, the non-slip flooring material can be laminated after about 1 to 8 hours, so that it is difficult to produce a lining board with an anti-slip layer in a manufacturing facility without a large site. .

  As shown in FIG. 1 and FIG. 2, the lining board 100 having the anti-slip layer according to the first embodiment of the present invention includes an upper plate part 10, a reinforcing part 20, a coating film guide part 40, and an anti-slip layer. It consists of M.

  Here, the lining board 100 provided with the anti-slip layer forms a temporary road surface that allows vehicles and people to pass over the road when excavating under the road surface for underground construction or providing a temporary bridge. Is provided on the upper side of the temporary support structure. At this time, the support structure is a plurality of iron beams such as a plurality of H beams or I beams arranged at predetermined intervals. That is, the lining plate 100 having a plurality of anti-slip layers is connected and arranged in a profile in which the upper surface is continuous between the respective iron beams, and the vehicle is placed on the lining plate 100 having the plurality of anti-slip layers. And people can pass. An anti-slip layer M is formed on the lining plate 100 provided with an anti-slip layer, and has an anti-slip effect.

  It is preferable that the upper plate part 10 is formed on a support structure and has a plate shape having a predetermined thickness capable of supporting a load applied from above. Specifically, the upper plate portion 10 is a generally rectangular flat plate, and both end portions in the longitudinal direction extend to a predetermined length so as to cover the space between the support structures. Thereby, both ends of the upper plate part 10 can be seated on the respective support structures adjacent to each other.

  The upper plate portion 10 is preferably made of a steel material that can be used in a cover section, an upper plate of a temporary bridge, a bridge repair section, and the like and can firmly support a load of a vehicle passing through the upper side. In some cases, the upper plate portion 10 is formed of an alloy or other metallic material and is not limited to the material, but is preferably formed of a rigid material in consideration of manufacturing cost, durability, corrosion resistance, fatigue strength, and the like. .

  A plurality of connection holes are formed in each corner of the upper plate portion 10 in order to facilitate the connection of the crane when the lining plate 100 having the anti-slip layer is transported or installed.

  A plurality of protrusions are formed on the upper surface of the upper plate part 10. The plurality of protrusions protrude above the upper plate part 10 at a predetermined height, and are spaced apart from each other at a predetermined interval, and are formed on the upper plate part 10 as a whole. Therefore, when the anti-slip layer M is formed, the contact area between the anti-slip layer M and the upper plate portion 10 is increased by the protruding portion, and the adhesion strength is improved.

  A reinforcing portion 20 is provided on the lower side of the upper plate portion 10 in order to reinforce the support strength against a load applied from above. The reinforcing part 20 includes a side plate part 11, a support member 21 and a rib member 22.

  Specifically, one end of the side plate portion 11 is connected to both ends of the upper plate portion 10 in the width direction, and the upper plate portion 10 extends to the other side so as to be separated from the support structure by a predetermined height. The side plate portion 11 extends perpendicularly to the upper plate portion 10 so as to firmly support both ends of the upper plate portion 10.

  The side plate portion 11 can be formed integrally with the upper plate portion 10 by bending both ends of the upper plate portion 10 downward.

  Thereby, since it can produce even if there is no cutting and welding process with respect to the upper-plate part 10 or the side-plate part 11, the number of processing processes is minimized and the manufacturability of a product improves. Further, since the upper plate portion 10 and the side plate portion 11 are formed integrally, the material has a minimum thickness, so that the material cost can be reduced and the economy is improved.

  Of course, depending on the case, the side plate portion 11 and the upper plate portion 10 can be separated. At this time, the side plate portion 11 can be connected to the upper plate portion 10 by welding or a separate fastening means, and the side plate portion 11 may be formed to have a thickness different from the thickness of the upper plate portion 10 so as to improve the reinforcing strength. it can.

One end of the support member 21 is coupled to the lower surface of the upper plate portion 10 by welding or a separate fastening means.

  Thereby, the support member 21 can provide the upper plate portion 10 with a restoring force that can be restored when the displacement amount of the upper plate portion 10 is generated by a load applied above the upper plate portion 10. That is, even if displacement occurs in the upper plate portion 10 due to a load applied when a vehicle or the like is passed, the support member 21 supports the lower side of the upper plate portion 10 as a whole, and the upper plate portion 10 is restored to its original shape. Can be restored.

  Therefore, the upper plate portion 10 can minimize deformation due to the load by the support member 21, and durability is improved. Moreover, since the upper part of the lining board 100 provided with the several anti-slip | slipping layer can be maintained to a continuous profile, the work amount concerning replacement or repair reduces, and maintenance repair property improves.

The deformation and separation of the support member 21 can be prevented.

  Since the lower surface of the upper plate portion 10 is entirely supported by the rib member 22 and the support member 21 and distortion due to the occurrence of displacement is minimized, not only the durability is improved, but also the product weight is reduced and the assembly process is simplified. It has the effect of improving productivity.

  Thus, when the anti-slip layer M is formed in the space portion s, the anti-slip floor material contacts the side surfaces of the first partition wall member 50a and the second partition wall member 50b together with the upper surface of the upper plate portion 10, so that the contact area Will increase.

  Accordingly, the non-slip flooring increases the contact area and improves the adhesion strength, and the slippage of the anti-slip layer M can be minimized, thereby improving the durability of the product.

  One of the first partition member 50a and the second partition member 50b is set lower than the other height. For example, the height of the first partition member 50a is set to be lower than the height of the second partition member 50b. One of the first partition member 50a and the second partition member 50b is formed with a communication hole communicating with the adjacent space portion s. As a result, when the anti-slip flooring material is applied, it is possible to stably fill the space portion s in communication with the adjacent space portion s, thereby improving construction convenience.

  The first partition members 50a are alternately arranged with the first partition members 50a adjacent to each other through the coating film guide portion 40. For example, when the second partition members 50b are spaced apart at predetermined intervals along the longitudinal direction, the first partition member 50a is disposed between the adjacent second partition members 50b and the coating film guide portion 40 and the second partition wall. It is alternately arranged between the members 50b, and is formed into a shape in which bricks are substantially laminated. That is, the first partition member 50a and the second partition member 50b are arranged such that the space s is formed in a predetermined pattern. Therefore, by arranging the first partition member 50a and the second partition member 50b at a predetermined interval, the space portion s is formed in a predetermined pattern, and the aesthetics of the product is improved.

  In this embodiment, it has been illustrated and described that the joint support portion 50 has a shape in which bricks are substantially laminated. However, in some cases, the joint support portion 50 may have a space portion s having a circular or polygonal shape. A partition wall member may be provided on the wall. For example, the partition member may have a honeycomb structure so that the space portion s is formed in a hexagonal shape. That is, the plurality of partition members can be arranged so that the space portion s forms patterns of various shapes, and these modified examples belong to the scope of the present invention.

  FIG. 5 is an exemplary view showing a state in which an unevenness forming roller is applied in a state where an anti-slip flooring material is applied to a lining plate having an anti-slip layer according to a second embodiment of the present invention.

  As shown in FIG. 5, the anti-slip layer M is pressed using the unevenness forming roller 1 in a state where the anti-slip floor material is applied in the coating film guide portion 40 in order to improve the anti-slip effect. Thus, the unevenness forming layer z can be formed.

  Specifically, a plurality of columnar pressure protrusions 1b arranged at predetermined intervals on the outer surface of the rotary body portion 1a are provided on the unevenness forming roller 1 in a radial direction. In some cases, the rotary body 1a may be formed of a vertical or horizontal frame that is spaced apart at a predetermined interval along the circumferential direction and has a predetermined thickness.

  The uneven forming roller 1 rotates on the upper surface of the upper plate portion 10 before the anti-slip floor material applied in the coating film guide portion 40 is cured. As a result, a concavo-convex forming layer z including a concave groove x and a convex portion y corresponding to the cross-sectional shape of the pressure protrusion 1b is formed on the upper surface of the anti-slip layer M.

  Therefore, the anti-slip flooring material is in close contact with the upper surface of the upper plate portion 10 while being pressed against the end surface of the pressure protrusion 1b by the rotational force and load of the unevenness forming roller 1, so that the adhesion strength of the anti-slip layer M is increased. More improved.

  The anti-slip flooring material is preferably applied to the upper surface of the upper plate portion 10, and the anti-slip layer M is preferably formed to a thickness of 3 to 5 mm. That is, the anti-slip flooring material is applied in the coating film guide portion 40, and the anti-slip layer M having a thickness of 3 to 5 mm is formed by the unevenness forming roller 1.

  As a result, the vehicle that moves on the upper plate portion 10 is further improved in the anti-slip effect due to the frictional force between the anti-slip layer M and the tire. Further, since the hydroplane phenomenon that may occur due to the change in the surface tension of the anti-slip layer M depending on the temperature can be minimized, the anti-slip effect on the road is further improved even in rainy weather.

  Here, it is preferable that the coating film guide part 40 extends so as to correspond to the thickness of the non-slip floor material to be applied. That is, the height h of the coating film guide part 40 is set corresponding to the thickness of the anti-slip layer M formed by applying the anti-slip flooring material.

  It is preferable that the partition member of the coupling support portion 50 extends to a height corresponding to the height h of the coating film guide portion 40. That is, the height of the first partition member 50 a and the second partition member 50 b is formed corresponding to the height h of the coating film guide portion 40.

  Thereby, when the coating height of the anti-slip layer M can be guided by the first partition member 50a and the second partition member 50b and a load is applied to the upper surface of the anti-slip layer M, the coating film guide unit 40, the first partition member 50a and the second partition member 50b support the load applied to the upper surface of the anti-slip layer M so as to be dispersed.

  For example, when the non-slip flooring material is applied to a thickness of 3 to 5 mm, the coating film guide portion 40 extends to a height of 3 to 5 mm. The first partition member 50 a and the second partition member 50 b extend to a height of 3 to 5 mm corresponding to the height of the coating film guide portion 40. As a result, the worker simply applies the anti-slip flooring material so as to correspond to the height h of the coating film guide part 40 and the height of the coupling support part 50 to form the unevenness forming layer z, thereby preventing the anti-slip layer M. The predetermined thickness can be guided.

  As a result, the operator can use the unevenness forming roller 1 to form the unevenness forming layer z corresponding to the height of the coating film guide part 40 and the coupling support part 50, so that the antislip layer M has a uniform coating film thickness. Therefore, construction convenience and workability are remarkably improved.

  In addition, the anti-slip layer M is supported by a joint support 50 extending in accordance with the height of the coating film guide 40, so that the lining plate 200 provided with the anti-slip layer can be moved up and down. Even when laminated in a direction or when a load is applied to the entire top surface, damage is minimized and product durability is further improved.

  In this embodiment, the shape in which the unevenness forming layer z is formed in a state where the upper plate portion 10 is provided with the coating film guide portion 40 and the coupling support portion 50 is illustrated. However, as in the first embodiment, The unevenness forming layer z can also be formed in a state in which the plate portion 10 is provided with the coating film guide portion 40.

  FIG. 6 is a perspective view showing a lining board provided with an anti-slip layer according to a third embodiment of the present invention. In this embodiment, the basic configuration excluding the protection unit is the same as that of the second embodiment described above, and a specific description of the same configuration is omitted.

  As shown in FIG. 6, the upper end of the coating film guide part 140 of the lining board 300 provided with the anti-slip layer is provided with a protective part 141 that is bent and extended inward. The protective part 141 may be formed integrally with the coating film guide part 140. That is, the coating film guide part 140 is formed by being bent downward from the end part of the protective part 141, and the end part of the curved coating film guide part 140 is welded to the end part of the adjacent coating film guide part. It is formed integrally with the membrane guide part 140.

  Since the coating film guide part 140 and the protective part 141 are integrally formed, the film thickness can be reduced to the minimum while having a uniform thickness, so that the material cost can be reduced and it is economical. Depending on the case, the coating film guide part 140 and the protection part 141 can also be integrally formed by methods, such as press work.

  At this time, the protection part 141 is formed so as to substantially cover the part where the joint support part 50 and the coating film guide part 140 are joined. Here, the coupling support part 50 can support the lower side of the protection part 141 and disperse the load applied from above.

  The coating film guide part 140 can be formed thicker than the protective part 141 in order to reinforce the support strength. When forming thicker than the thickness of the protection part 141, the coating-film guide part 140 and the protection part 141 are isolate | separated, and can be couple | bonded by welding or another fastening means.

  The coating film guide part 140 and the protection part 141 are preferably made of a metallic material so that they can be firmly supported by a load applied from above. Of course, the coating film guide part 140 and the protection part 141 can be formed of an alloy or other metal material in consideration of manufacturing cost, durability, corrosion resistance, fatigue strength, and the like.

  FIG. 7 is an exemplary view showing a state in which a lining plate provided with a non-slip layer according to the third embodiment of the present invention is laminated.

  As shown in FIG. 7, the cover plates 300A and 300B that have been assembled and have a plurality of anti-slip layers can be stacked in the vertical direction in order to improve the efficiency of the space. Thereby, the load of the lining board 300B provided with the other side non-slip layer is applied to the upper side of the lining board 300A provided with the one-side anti-slip layer.

  Here, the lining plate 300A provided with the one-side anti-slip layer includes an anti-slip layer provided substantially below the lining plate provided with the anti-slip layer laminated in the vertical direction. Can be understood as a lining board.

  The protection part 141 can be extended to a width where the alignment seat part 30 is seated. Specifically, the lower ends of the seating extension part 31 of the lining plate 300B provided with the other side anti-slip layer are seated on the upper surface of the protection part 141 of the lining plate 300A provided with the one side antislip layer, respectively. Is done.

  The protective part 141 of the lining plate 300 </ b> A provided with the one-side anti-slip layer substantially covers the upper edge part of the anti-slip layer M by being bent inward from the upper end of the coating film guide part 140 and extending.

  Here, the extension width of the protection part 141 can be set in a range of 160 to 200% of the height h of the coating film guide part 140. For example, when the height of the coating film guide part 140 is 5 mm, the extension width of the protection part 141 can be set to 8 to 10 mm.

  At this time, when the extended width of the protective part 141 is less than 160% of the height h of the coating film guide part 140, the protective part 141 depends on the laminated state of the lining plates 300A and 300B having a plurality of anti-slip layers. Both ends of the lower part of the seating extension 31 are not seated on the upper side, and a load can be applied in contact with the anti-slip layer M.

  Therefore, the lower end of the seating extension part 31 of the lining board 300B provided with the other-side anti-slip layer is set by setting the extension width of the protection part 141 in the range of 160 to 200% of the height of the coating film guide part 140. Can be seated on the upper surface of the protection part 141 of the lining plate 300A provided with the one-side anti-slip layer, and the anti-slip layer M can be formed smoothly.

  This prevents direct contact between the anti-slip layer M of the lining plate 300A provided with one side anti-slip layer and the lower end of the seating extension 31 of the lining plate 300B provided with the other side anti-slip layer. it can.

  Therefore, the anti-slip layer M of the lining plate 300A provided with the one-side anti-slip layer is supported by the protective portion 141 so that the load applied to the lining plate 300A provided with the one-side anti-slip layer is dropped or cracked. The defect rate due to occurrence can be minimized. In addition, even if the anti-slip layer M is formed on the lining plate 300 provided with the anti-slip layer, that is, when the product is completely manufactured, it is possible to minimize the occurrence of the product defect rate. Therefore, maintenance repairability is significantly improved.

  Further, even if a separate member for protecting the anti-slip layer M is not provided, the lining plate 300B provided with the other-side anti-slip layer on the upper side of the protective portion 141 of the lining plate 300A provided with the one-side anti-slip layer. Therefore, the convenience of work is further improved.

  Since the lining board 300 with the non-slip layer is easy to stack and store, not only the efficiency of the storage space is increased, but also the production of the product is completed when it is used for installation on the support structure. Since it is in a state, it can be installed without any additional work, and the work efficiency is improved.

  Further, the lining plate 300 provided with the anti-slip layer is protected by the protective part 141 even if the anti-slip layer M is laminated in the vertical direction before the anti-slip layer M is cured in the manufacturing process. It is possible to manufacture even in a manufacturing facility that does not have, and the production efficiency is improved.

  In some cases, the extension width of the protection part 141 can be set in accordance with the distance between one end of the upper plate part 10 and the opposing inner surface of the alignment seat part 30.

  Here, the opposing inner surface of the alignment seat 30 can be understood as an inner surface where the pair of alignment seats 30 disposed opposite to each other at the lower portion of the lower plate portion 11a are opposed to each other.

  At this time, the extended width of the protection part 141 is a distance between one end in the longitudinal direction of the upper plate part 10 and the opposing inner surface of the alignment seating part 30 disposed adjacent to one end in the longitudinal direction of the upper plate part 10. Can be set accordingly.

  Here, the interval between them can be understood as a distance from one end of the upper plate portion 10 in the longitudinal direction to the opposing inner surface of the alignment seat 30.

  Therefore, the entire lower end of the seating extension 31 of the lining plate 300B provided with the other-side anti-slip layer is in contact with the upper surface of the protective portion 141 of the lining plate 300A provided with the one-side anti-slip layer stably. I can arrive.

  Thereby, since the area where the lining board 300B provided with the other side non-slip layer is seated increases and can be laminated more stably, stability and workability are improved.
