Description

Stone block for sidewalk pavement and construction method {Stone Block And Construction Method There Of For Side Walk Packing}

The present invention relates to a paving stone block for structurally strengthening the bonding force with cement and a construction method thereof, and more specifically, mortar penetrates into the bottom part and can be unevenly coupled to each other in dry construction without an adhesive. Regarding the paving stone block and its construction method, which can double the shock absorption while preventing the positional separation (separation) due to the temperature change by significantly improving the bonding force between cement (concrete) and the stone block with different physical properties. will be.

Currently, the replacement of concrete cement blocks is relatively expensive, but stone blocks, which are excellent in both durability (strength) and decorative properties (natural texture and patterns unique to stone), are increasingly used for road pavement.

The stone block used for paving paving is about 1,600 in strength and superior to cement blocks, and the absorption rate that absorbs moisture such as rainwater is only about 0.3. Of course, the service life is long enough that it is incomparable with cement blocks.

Stones having such a unique texture and excellent strength are used in various applications for construction, civil engineering, and crafts. In particular, natural intrinsic colors as natural materials are not deteriorated, and thus the decorative design is high.

On the other hand, the stone blocks applied for sidewalk paving are usually applied with a thickness of about 30-40mm, and the bottom surface hidden without being exposed to the outside by being settled toward the concrete on the bottom sand layer is processed to a cutting surface of about # 200. It is installed and fixed on the concrete through mortar in the processed state.

By the way, as shown in Figure 1, the stone block applied to the installation paving is a general construction structure that is combined to be installed on the concrete 30 above the bottom sand layer 40, which is a cement (concrete) ( After pouring a certain thickness of 30, it is being constructed by the adhesive method to put the stone block 10 on it using the mortar (20).

Even in the case of the cement bonding method, many defects are generated because the bonded joints between the stone blocks 10 and the cement 30 having different physical properties (materials) are separated within a few years after the construction. This is because the temperature change between winter and summer is about 50-60 ℃ throughout the Republic of Korea.

Eventually, the temperature of the externally exposed stone block 10 should be absorbed by the cement (concrete) located on the bottom side, but the thermal conductivity decreases due to the difference in strength between them. In such a phenomenon, the stone block is cement when heat of 50 degrees is generated in summer. Must absorb 50 degrees of heat, but when the strength of cement is 250, thermal conductivity is inevitably reduced due to the difference in strength of 1,500: 250 ratio.

At this time, the adhesive site (film) between the stone block 10 and the cement (concrete) 30, which can only be vulnerable, is easily dropped. That is, cement (concrete) also shrinks as the temperature changes of the stone, and shrinkage occurs as the temperature changes, so that the adhesion between each other is poor, and thus the positional fixation of the stone block may be weakened due to the weakening of the fixed fixing force.

Particularly, in winter, when the temperature change is relatively high, the expansion phenomenon due to the high absorption rate of cement is inevitably worsened, and the positional deviation of the stone block may be more problematic in winter.

In addition, the problem in the construction structure of the stone block is an impact, the stone block is a strong impact is transmitted to the strong. In contrast, cement is relatively weak in strength and thus has little impact absorption. Therefore, even in the case of the wet construction structure, when the impact is applied to the stone block, it is difficult to solve the problem that the defect occurs because the adhesion between the stone block and cement falls.

As a result, in the construction structure in which a simple type of stone block is fixed on cement (concrete), it is difficult to prevent the stone block from slipping and inclining.

In addition, when the existing concrete (cement) is poured in order to construct the stone block and the stone block is constructed, there is a disadvantage in that a lot of removal cost is incurred. The maintenance is inevitable.

Accordingly, the present invention is a simple stone block invented to solve the structural problems of the existing stone block is easily peeled and separated from the cement due to the difference in strength and thermal conductivity is installed and bonded to the cement (concrete) of different floors In the installation of the stone block on the cement, the mortar, which acts as an adhesive and a buffer material, penetrates into the bottom part of the stone block and can be unevenly combined to allow the adhesive area of the stone block to be structurally widened. As a result, the bonding force between cement (stone) and stone block can be improved dramatically.The new bonding structure can maintain stable state against external impact as well as physical property change such as shrinkage and expansion due to temperature change after construction. The purpose is to provide a paving stone block and its construction method. The.

The sidewalk paving stone block of the present invention for achieving the above object, in constituting the sidewalk paving stone block is installed on the cement (concrete) of the ground bottom, basically to the bottom surface of the stone block on the cement side Mortar on the cement (concrete) is characterized in that the concave-convex grooves are cut out to a depth of 1/3 ~ 1/2 of the thickness so that the mortar penetrates and is combined into an integral structure.

In addition, the stone block has a plurality of uneven grooves formed on the bottom of the mortar of the mortar on the cement (concrete) is bonded and fixed to the mortar on the cement (concrete) during the construction work in a structured state in which the upper surface of the mortar penetrated and filled before the construction work The structural features of the application structure can be achieved. In particular, the mortar integrally structured before the construction work on the bottom surface of the stone block is preferably formed to the same thickness as the thickness of the stone block.

And in the construction method of the paving stone block applying the stone block according to the present invention, the sand layer is uniformly laid on the ground floor, which is basically polished, the sand layer is placed on the cement layer (concrete) and the mortar is applied thereon Then, a stone block formed with a plurality of recessed and recessed grooves is installed on the bottom surface, and the construction process is performed so that the upper side of the mortar below is penetrated and combined into an integral structure.

In addition, the stone block is a pre-work before bonding to the mortar coated on the cement (concrete) by bonding the mortar to the bottom of the stone block formed with recessed grooves, the mortar is integrally structured to the stone block cement (concrete) ) Has a technical feature that can be installed by mounting the mortar above to be integrally coupled between the upper and lower mortar of the same material.

As described above, the sidewalk paving stone block and the construction method of the present invention, unlike the existing stone block, basically bonded to the cement by forming a notch groove that can extend the joint surface with mortar on the bottom surface The surface can be structurally lowered, and furthermore, it is structurally more securely bonded by installing on the mortar coated concrete of the same material with the mortar on the bottom of the stone block. It can be kept fixed.

In other words, mortar may be partially penetrated into the bottom of the stone block to be concave and convex, and thus, the adhesive force between cement (concrete) and the stone block, which have different physical properties, can be greatly reduced even by dry construction without an adhesive. It is expected to provide an effect that doubles shock absorption while suppressing positional displacement (separation) even in overexpansion.

This basically puts the stone block on the site for sidewalk paving, which gives the stone block an uneven surface to widen the adhesive surface to enhance the adhesive strength, which can bring the convenience of sidewalk maintenance and eliminate the need for thick stone. In addition, the construction method so far has not been possible to dry construction by concrete pouring, but the cement mortar is buried to a certain depth by the uneven groove of the bottom of the stone, so as to act as a fixing pin in accordance with the solidification of the cement mortar, sinking, Even if vibration or the like occurs, an effect that can firmly support the stone block as the sidewalk block can be provided.

Hereinafter, according to the present invention, not only to suppress the sliding phenomenon by structurally strengthening the adhesive surface with the cement, but also to improve the impact absorption and absorption rate and the decorative properties as a natural material, paving stone blocks for dry construction and Detailed configuration relations and principles of the construction method will be described in detail with reference to the accompanying drawings of preferred embodiments. For reference, for convenience of description, the concrete on the bottom side where the stone block of the present invention is installed will be described mixed with cement.

First, as shown in the drawings of FIGS. 3 and 5, the stone blocks are installed on cement (concrete) of the ground floor, and structurally between the lower concrete 20a and the upper stone blocks 10 of different materials. The stone block 10 is formed to form a strong adhesive surface and to be reliably integrally structured.

That is, the stone block 10 to be applied in the present invention is filled with the mortar (20a) applied by the adhesive (bonding) means on the cement (concrete) to the bottom surface 16 of the stone block toward the concrete 30 is naturally infiltrated and filled In order to be coupled to the integrated structure, the stone block 10 has a plurality of recessed grooves 12 are formed in the bottom surface 16 to a depth of about 1/3 to 1/2 of the thickness itself. At this time, the uneven groove 12 is preferably formed to be cut both sides in the longitudinal direction to open rather than grooved in the bottom surface of the stone block 10, which is to improve the economics and workability due to the material characteristics of the stone block 10 For sake.

Thus, the stone block 10 of the present invention, in which the bottom surface 16, not the shape of a simple rectangular parallelepiped form a plurality of uneven grooves 12, is naturally seated on the mortar 20a applied to the concrete 30. Once installed, the mortar 20a naturally penetrates and fills the inside of the uneven groove 12 by a load, so that the mortar 20a can be reliably integrally structured, which results in a simple dry construction method without applying wet construction method. Also through the concrete 30, the material 30 can be simply structured and reliably coupled to the stone block 10 to be integrally structured.

That is, the stone block 10 according to the basic embodiment of the present invention is a simple construction method to allow the mortar 20a of the concrete 30 to be filled with the concave-convex groove 12 formed on the bottom surface 16, and heterogeneous materials. By improving the bonding force between these concrete 30 and the stone block 10 so that it can be maintained and preserved stably as an integral structure without any problems even in the contraction and expansion caused by 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, as shown in the drawings of Figures 2 and 3, after the sand layer 40 is uniformly laid on the ground floor, which is basically well trimmed, Of course, the cement (concrete) 40 is poured onto the sand layer 40 and mortar 20a is applied by means of bonding and buffering before the stone block 10 is seated and installed thereon.

And when the stone block 10 formed with a plurality of uneven grooves 12 formed on the bottom surface is placed on top of the mortar 20a of the concrete 30 to be squeezed and installed, the upper side of the mortar 20a of the lower side is naturally the stone It may be infiltrated and filled into the uneven groove 12 of the block 10.

At this time, the mortar 20a preferably maintains a thickness of about 1/3 for the stone block 10 having a thin plate structure of approximately 60 mm, thereby achieving a more stable shock absorbing structure as a mitigating layer against external impact. In addition, the concrete 30 forming the bottom of the sand layer preferably forms a relatively thick support layer of about 200 mm.

And the present invention, unlike the basic embodiment of Figures 2 and 3, as shown in the drawings of the application embodiment of Figures 4 and 5, the stone block 10 in advance as a separate mortar (20b) product before construction work concrete The same material as that of the mortar 20a to be applied on the 30 can be more reliably mutually fixed.

That is, the stone block 10 is not a structure having a thickness that directly couples the mortar 20a of the concrete 30 in the basic embodiment, but is about 30, which is about half the thickness of the stone block 10 according to the basic embodiment. In the form of a thinner thin plate in and out of mm, the separate mortar 20b is first combined integrally with the bottom surface on which the uneven groove 12 is formed, which is reliably coupled to the mortar 20a of the concrete 30 as the same material. By being fixed, these stone blocks 10 and mortar 20b may be formed and applied again to a thickness of 60 mm, such as the independent stone blocks 10 of the basic embodiment.
