Description

Footpath block of crosswalk with anti-slip function {Footpath block of crosswalk with a sliding safety function}

The present invention relates to a sidewalk block having a non-slip function that is also structurally non-slip and has a high bonding force, more specifically, such as winter, while maintaining a firm coupling state to the concrete layer (cement) of different floors Even in harsh environments, pedestrians, especially on pedestrian crossings with slopes, can be guided to walk safely without slipping, and rainwater can be reliably discharged even in rainy weather so that they can walk safely. A sidewalk block of a crosswalk having a non-slip function.

At present, it is relatively expensive to replace cement blocks, but the stone blocks (stones), which are more effective in both durability (strength) and decorativeness (natural texture and patterns unique to the stone), are gradually replaced as sidewalk blocks on the road (India). The trend is using.

The stone block used as the road sidewalk block has superior durability compared to cement block, and its absorption rate that can absorb water such as rainwater is much lower than that of cement block. Due to its low physical properties, its service life is long enough to be incomparable with cement blocks.

In addition, stone blocks are generally applied to roads with a thickness of about 30-40 mm, which is relatively thinner than cement blocks. In the case of the bottom surface that is hidden without being exposed to the outside, it is usually combined on a concrete layer placed on the sand layer of the floor. It is common to install and fix it on the concrete layer of the floor between mortars while the surface is processed to roughness # 200.

Generally, the stone blocks that are installed for sidewalk pavement are generally installed on concrete layers laid on the sand layer of the floor. This is based on the soil condition of the floor. The sidewalk block of the road is completed as a construction structure that puts stone blocks.

However, even when the stone block is constructed by the adhesive method of the concrete layer, there is a problem that the bonded joints between the stone block and the concrete layer having different physical properties (materials) are easily separated and separated within a few years after the construction. As the temperature change between winter and summer is 50-60 ℃, the troublesome maintenance is required more than necessary.

Eventually, the exposed concrete blocks must be absorbed by the concrete layers at the bottom, but the thermal conductivity decreases due to the difference in strength between them. In such a phenomenon, the stone blocks have a high level of heat when cement generates high heat in summer. The thermal conductivity is inevitably reduced due to the absorption, and the adhesive site (film) between the stone block and the concrete layer, which is inevitably weak, falls easily.

That is, as the concrete layer also shrinks due to the temperature change of the stone, the shrinkage phenomenon occurs as the temperature changes, and thus the adhesion state between each other is poor, resulting in the weakening of the bonding force between the concrete blocks and the positional deviation of the stone block from the concrete layer. Particularly, in winter, when the temperature change is relatively high, the phenomenon of expansion due to the high absorption rate of the concrete layer is more severe, which may further cause the positional deviation of the stone block.

In addition, a problem in the construction structure of the stone block is a shock, the stone block is a strong impact transmitted because of the strong strength, in contrast, in the case of cement, the strength is relatively weak, the impact absorption is low. Therefore, even in the case of a wet construction structure, when the impact is applied to the stone block, the adhesive portion between the stone block and the cement falls, which means that in the construction structure in which the simple block is installed and fixed on the concrete layer, the stone block is removed from the cement of the concrete layer. It was difficult to prevent the separation and separation phenomenon.

In addition, when the current concrete layer is laid to install the stone blocks and the stone blocks are installed, the removal cost is incurred during road repair.In the case of using the cement blocks currently in use, of course, they are easily discolored or damaged in terms of their structural properties. This is happening and the maintenance is inevitable that much. It is difficult to remove the ice block because the cement block can be easily corroded when the snow is snowed and the surface of the ice becomes sprayed with calcium chloride, which is a snow removing agent.

On the other hand, the sidewalk block on the crosswalk side slopes smoothly from the side of the sidewalk to the relatively low crosswalk, which allows pedestrians as well as disabled people with disabilities to easily enter and cross the sidewalk side of the sidewalk. In particular, the sidewalk block on the sidewalk side is also equipped with a separate entry sign for the disabled so that people with disabilities can easily know the entry position of the crosswalk side.

However, in the case of a sidewalk block on a sidewalk, which is a flat sidewalk block as well as a cross section, the exposed top surface of the sidewalk block can be easily iced in the cold winter season. The risk of a safety accident such as slipping is structurally present.

As a result, the sidewalk block on the crosswalk side is also separated and separated from the concrete layer of the existing sidewalk block, and in particular, the freezing of the sidewalk block occurs more easily in winter due to its inclined features. As a result, the risk of safety accidents such as bruises or fractures as the handicapped or the elderly slip and fall is a problem.

Therefore, the present invention is basically a stone block constituting the sidewalk block is constructed so as to maintain a fixed and structurally securely bonded to the concrete layer of the floor with different physical properties, easy separation from the cement of the concrete layer due to the difference in strength and thermal conductivity It is possible to structurally solve all the problems of the existing stone blocks that are dislodged. As a result, the solid stone blocks are bonded to the concrete layer (cement) of different floors. Even in pedestrian crossings, people with disabilities who are inconvenient to walk can be guided to walk safely without slipping, and in rainy weather, rainwater can be reliably discharged to the low stone blocks on the crosswalk, so that they can walk safely. New block with high reliability In particular, people with disabilities, who are structurally inconvenient, make it easier to enter the crosswalk, and they do not slip structurally during rain or winter, and they are also firmly connected to the floor even when the strong snow removal material, which is a corrosion component of winter, is introduced. It is an object of the present invention to provide a sidewalk block having a non-slip function of the new structure having a variety of effects, such as to be continuously maintained.

In order to achieve the above object, the sidewalk block having a non-slip function according to the present invention basically constitutes a sidewalk block in which a stone block is installed and coupled through a mortar layer on a concrete layer of a floor. A plurality of binding grooves are formed on the bottom surface so that a part of the mortar layer penetrates into the binding grooves and is integrally coupled. A plurality of friction grooves are formed on the upper surface of the stone block so as to prevent pedestrians from slipping. A plurality of drainage grooves are formed along with the friction groove in the stone block of the crosswalk side of the crosswalk to allow the molten snow to drain externally smoothly.

The stone block has a rectangular groove with a non-slip friction groove formed on the upper surface so that a disabled person who is a pedestrian walks on the inclined entry slope on both sides of the pedestrian crossing on the pedestrian crossing. An entry guide protrusion protrudes, and a circular stop display protrusion protruding on the upper side and a rear side of the sidewalk side has a friction groove of an anti-slip function formed thereon so as to sense that the crosswalk is reached at both front and rear sides thereof.

In addition, the stone block is formed in the shape of a square or diamond square pyramid friction grooves grooved by the anti-slip function in the entry guide projection and the stop display projection protruding on the upper surface or the upper surface. In addition, the stone block is formed in the recess in the front and rear width direction only the binding groove which is integrally coupled to a part of the mortar layer in the bottom.

In particular, the stone block is a gap between the joints of the stone block and the stone block during the construction of the stone block to the mortar layer so that a strong bonding state with the lower cement mortar layer can be maintained even in the use of strong snow removing material which is a winter corrosion component. It is characterized in that the constituent relationship that the stone block is in close contact with each other as the liquid cement adhesive mixed with the adhesive component is introduced into the mortar layer and penetrated to the upper side of the mortar layer.

As described above, the crosswalk sidewalk block having a non-slip function according to the present invention, unlike the existing stone block, basically by forming a notch groove that can extend the bonding surface with the mortar on the bottom cement The adhesive surface with can be lowered structurally. In addition, it is possible to maintain a more stable bond fixed structurally by installing on the concrete layer coated with the mortar of the same material in the state in which the mortar is integrally structured on the bottom of the stone block before the construction work. That is, the mortar may be partially penetrated into the bottom of the stone block to be concave and convex, and thus, the adhesive force between the concrete layer (cement) and the stone block, which have different physical properties, even with dry construction without a separate adhesive, is dramatically improved according to the temperature change. It is expected to provide an effect that doubles shock absorption while suppressing positional deviation (separation) even in contraction and expansion.

This can basically strengthen the adhesive force by widening the adhesive surface by placing irregularities on the stone block in the field construction as a sidewalk block, which can bring the convenience of maintenance of the sidewalk block, and the construction method so far Although dry construction was not possible due to the casting of concrete layers, the mortar is buried deeply into the binding groove of the bottom of the stone block, so that the cement mortar layer hardens to act as a fixing pin so that settlement, vibration, etc. occur. It can also be provided with the effect that can firmly support the stone block as a sidewalk block structure.

In addition, when the present invention is applied to the sidewalk block of the inclined position, such as the disabled sidewalk of the crosswalk as well as the usual sidewalk sidewalk, ice on the top of the stone block in the snow or moisture in cold weather, especially in winter Even if it occurs, it can be structurally prevented from freezing by releasing snow or moisture to the surroundings because there is no concern about corrosion even if calcium chloride is used immediately due to the characteristics of the stone block. It can even provide the ability to walk more safely without slipping. Furthermore, this is expected to contribute to the creation of a pleasant aesthetic and pleasant urban environment visually by exposure of the stone blocks formed in various grooves.

Hereinafter, according to the present invention, by strengthening the bonding surface bonding state with the mortar layer, not only to suppress the separation and separation phenomenon, but also to improve the shock absorption and absorption rate and decorativeness as a natural material, dry construction may be possible. Even in the case of the stone block of the inclined entrance slope and the crosswalk area where the entry indication means is formed, the friction force is normally exerted to prevent it from slipping, and in particular, the natural discharge of rain water during the rain, so that it can maintain a clean surface condition and cold winter season. The use of ice-making materials to melt snow on the road prevents corrosion between the stone blocks and the mortar layer, thus allowing the pedestrians to walk safely without slipping, while also dramatically increasing the durability and decoration of the product itself. Slip of safety structure A preferred embodiment in conjunction with the accompanying detailed configuration management and operation principle of the pedestrian crossing press block having an anti-see example diagram will be described in detail. For reference, the mortar layer 20 on the concrete layer 30 on which the stone block 10 of the present invention is installed is basically a mortar layer in which a part of the mortar layer 20 is pre-infiltrated into the grooved bottom 16 of the stone block 10. 20b) and a part of the mortar layer 20a placed above the concrete layer 30 on the bottom may penetrate into the grooved bottom 16 of the stone block 10 during construction, and for convenience of drawing and description, 20 or 20a and 20b can be used interchangeably.

First, the stone block 10 applied to the sidewalk block of the present invention, as shown in FIGS. 1 and 2, the stone block 10 is seated on the mortar layer 20 on the bottom (ground) cement concrete layer 30. Installed and integrally structured, the stone block 10 is formed to form a structurally strong adhesive surface between the lower mortar layer 20 and the upper stone block 10, which are different dissimilar materials, to be reliably integrated.

That is, the stone block 10 to be applied in the present invention is a mortar (20) applied by the adhesive (coupling) means on the concrete layer 30 of the floor to the base 16 is installed on the mortar layer 20 is coupled to naturally In order to be infiltrated and combined into a unitary structure, the plurality of binding grooves 12 are formed at a level of about 1/6 to 1/4 of the thickness of the stone block 10 itself and without causing any problems in the product strength of the stone block. Notches are formed on the bottom surface 16. At this time, the binding groove 12 through which the mortar layer 20 penetrates is preferably formed to be cut open so that both sides are opened in the front and rear width direction rather than being recessed in the bottom surface 16 of the stone block 10, which is the stone block 10. Due to the material characteristics of the material, it forms a stable cut groove structure that can improve economic efficiency and workability.

Thus, the stone block 10 of the present invention, which forms a plurality of binding grooves 12 rather than the shape of a simple rectangular parallelepiped having a bottom surface 16, is naturally seated and installed on the mortar 20 coated on the concrete layer 30. When the mortar layer 20a naturally penetrates into the binding groove 12 by the load and is hardened while filling, it can be reliably integrally structured, and as a result, even through a dry construction method without applying a wet construction method. It is possible to simply and reliably press-bond the stone block 10 to work on the concrete layer 30 is a different material can be integrally structured.

That is, the stone block 10 according to the basic embodiment of the present invention is also a simple construction method to allow the mortar layer 20 on the concrete layer 30 to be filled with the binding groove 12 formed on the bottom surface 16. In addition, by improving the bonding force between the concrete layer 30 and the stone block 10, which is a heterogeneous material, it can be maintained and preserved stably as an integrated structure without any problems even in contraction and expansion due to external impact or temperature change.

On the other hand, the stone block 10 is formed and applied as a basic embodiment of the present invention basically laid a sand layer evenly on the ground floor is well polished, then, of course, the concrete layer 30 is poured on the sand layer, and thereon Before mounting the stone block 10 is installed mortar layer 20 is applied by the adhesion and buffer means.

And when the stone block 10 formed with a plurality of binding grooves 12 is formed on the bottom surface and placed on the mortar layer 20 on the concrete layer 30 and pressed to install, naturally the upper side of the mortar layer 20a at the bottom It may be infiltrated and filled into the binding groove 12 of the stone block 10. At this time, the mortar (20a) is to maintain a more stable impact absorbing structure as a mitigating layer for external impact by maintaining a thickness of about 1/3 about the stone block 10 of the thin plate structure of approximately 60mm. In addition, the concrete layer 30 forming the bottom of the sand layer is usually formed to form a relatively thick support layer of about 200mm.

The stone block 10 applied to the sidewalk block of the present invention is more reliably made of the same material as the mortar layer 20a applied to the concrete layer 30 after being commercialized as a separate mortar layer 20b before construction work. Can be fixed to each other.

In other words, the stone block 10 is not a structure of the thickness of directly bonding to the mortar layer 20a of the concrete layer 30 in the basic embodiment, unlike the stone block 10 according to the basic embodiment is about half the thickness In the form of a thinner thin plate of approximately 30 mm in and out, the first separate mortar layer 20b is first integrally bonded to the bottom surface 16 on which the binding groove 12 is formed, and the mortar layer 20a of the concrete layer 30 is formed. By making sure that the same material is securely coupled to the same material, these stone blocks 10 and mortar 20b may be formed and applied again to a thickness of 60 mm as the independent stone blocks 10 of the basic embodiment. have.

In particular, the sidewalk block according to the present invention is exposed to the upper surface 14 of the stone block 10 so that both normal pedestrians and disabled pedestrians can safely walk and enter the crosswalk without slipping without weather conditions such as rain or snow. Basically, the friction groove 15 is formed. That is, as shown in Figures 3 to 5, the rainwater falling during the usual rainy day as well as structurally naturally drained to the sidewalk side of the roadway or sidewalk relatively lower than the sidewalk side of the stone block 10 so that the pedestrian does not slip A friction arc 15 of a certain depth is formed in the form of a lattice with respect to the externally exposed upper surface 14.

In particular, the friction groove 15 of the stone block upper surface 14 that is exposed to the outside is not relatively exposed to the binding groove 12 of the bottom 16 that is coupled to the lower mortar layer 20 of course without being exposed externally 6A and 6B, the friction groove 15 formed like a scratch on the top surface 14 of the stone block 10 is a lattice-shaped square or diamond. It may be formed in a variety of irregularities that may generate a friction force that does not slip easily pedestrian in the form of a square pyramid.

The stone block 10 applied to the crosswalk sidewalk block of the present invention is basically inclined at both sides about the crosswalk side crosswalk portion 10d, as shown in the application examples of FIGS. 4 and 5 and 7. Friction grooves 15 are formed to prevent pedestrians from slipping through both the entry slope portions 10b and 10c and the traffic sidewalk portions 10a on the side of the side that are relatively higher than the crosswalk portions 10d, In particular, the stone block 10 of the crosswalk side crosswalk portion 10d is formed with a plurality of drainage grooves 13 together with the friction grooves 15 on the upper surface thereof.

This allows natural drainage of rainwater during rain, as well as smooth drainage of snow melted by cold snow removal. In addition, the drainage groove 13 formed together with the friction groove 15 in the stone block 10 of the crosswalk portion 10d may have a relative drainage function as compared with the friction groove 15 having the friction function. It is preferable that the groove is deeply formed.

That is, the drainage groove 13 is also formed deeper than the friction groove 15, but of course it must be formed much thinner than the binding groove 12 of the opposite bottom so as not to cause any problems in the overall durability strength of the stone block 10. do. Preferably a depth of 1/2 to 1/4 level of the binding groove 12 formed on the bottom so that the bonding force with the mortar layer 20 is not a problem in the basic function of the stone block 10 of the present invention is prioritized The drainage groove 13 is formed, and the friction groove 15 is preferably formed at a level of 1/4 to 1/6 of the drainage groove 13 so that the frictional force of the pedestrian can be exerted. Do.

On the other hand, the crosswalk sidewalk block of the present invention is different from the crosswalk side (10a) and the crosswalk side (10d) of the sidewalk side of the flat sidewalk inclined entry sites (10b) (10c) are constructed in an inclined form between them Friction grooves that exhibit frictional force as a whole, regardless of the location where the stone block 10 is installed, so that pedestrians of normal people as well as pedestrians of people with disabilities who are uncomfortable to walk can safely walk and enter. 15) is formed, in particular the stone block 10 of the crosswalk side 10d of the crosswalk side, such as rain water or water drained through the passage section (10a) and the entry slope (10b) (10c) A drain groove 13 is formed so that it can be smoothly drained out of the sidewalk.

In particular, as shown in the drawing of the developed application embodiment of FIG. 7, a person with a disability who is a pedestrian walks on both inclined entry slope portions 10b and 10c around a crosswalk side crosswalk portion 10d and is on the road side. A rectangular entry guide protrusion 17 protrudes from the upper surface 14 of the stone block 10 so as to reliably detect that the vehicle is entering the crosswalk, and along with the entry guide 17, the crosswalk side of the driveway. The circular stop is formed in the part 10d so that the friction groove 15 of the anti-slip function is formed on the upper surface 14 of the stone block 10 so that the crosswalk can be detected (recognized) at both front and rear sides thereof. The display projections 18 protrude. Of course, it is preferable that the friction groove 15 is formed on the upper surfaces of the entry guide protrusion 17 and the stop display protrusion 18 so that the friction force can be more reliably exerted.

In addition, the sidewalk block of the crosswalk having an anti-slip function of the present invention, as in the more advanced embodiment of Figure 9, even when the use of strong snow removal material of the winter corrosion component, the stone block 10 does not generate corrosion and the bottom mortar layer 20 The adhesive composition is mixed in the gap between the joints of the stone block 10 and the stone block during the construction of the stone block 10 for the mortar layer 20 so that the firmly coupled state of the stone block can be maintained continuously. As the liquid cement adhesive 40 for stone is introduced and penetrated to the upper side of the mortar layer 20, the stone block 10 may be more tightly coupled and may have a corrosion prevention function.

In addition, the stone block 10 that can be applied to the operation principle of the present invention is not only the disabled access road of the crosswalk which is mainly constructed in an inclined form, but also the stone of the present invention in various sidewalk blocks in which ordinary sidewalk blocks or other pedestrians go. Various types of drainage grooves 13 and friction grooves 15 applied to the block 10 can be widely applied.

This allows the pedestrians to walk comfortably during rainy days, as well as to make sure that the pedestrians do not slip and are safe to walk. In addition, the stone blocks can be used for snow or moisture in cold weather such as winter. Even if the freezing occurs on the upper surface of the) and the highly corrosive snow removal material 40 is administered, the corrosion can be prevented from occurring between the stone block 10 and the stone block or the mortar layer 20 under the stone block. Even durability can be significantly improved.
