Description

Prefabricated Composite Block {PREFABRICATED COMPOSITE BLOCK}

The present invention relates to a block installed on an outdoor floor surface such as a sidewalk, a parking lot, a park, or a playground, and more specifically, the lower block made of synthetic resin and the upper block made of cement mortar are assembled so that they can be detached It relates to a composite block installed on an outdoor floor surface.

Cement blocks are usually paved on sidewalks or bicycle paths separated from roadways, promenades along streams, parks, and parking lots.

These cement blocks are constructed in such a way that sand is laid on a sub-base layer of 10 to 15 cm in thickness that supports the load on the top, and it is compacted to form a stable layer with a thickness of about 3 cm, and is placed on the upper surface of the sand of the stable layer. In addition, the sand in the stability layer should be laid and compacted so as to have a horizontal and uniform surface.

However, in the installation structure of the block paved by the above construction method, when the sand of the stable layer is lost due to rain, etc. during long-term use, a part of the lower surface of the block is dented and the flat surface is broken, and the block is placed in an unstable state, causing a lot of inconvenience to pedestrians. do.

In addition, grass grows through the gaps between blocks, impairing the appearance of the pavement, and even the block itself is frequently damaged as the gap between blocks widens. In addition, when some blocks are damaged, it is necessary to re-construct over a large area up to a certain range, so maintenance costs are high.

On the other hand, the inventor of the present application has proposed an assembly-type synthetic resin block as Patent Registration No. 10-1777216 for ease of paving construction and for easy replacement of only the damaged blocks when some blocks are damaged.

The assembly-type synthetic resin block is provided with a fixing groove in the lower body and a fastening protrusion that is inserted downwardly into the fixing groove in the upper body, and is assembled up and down to form one synthetic resin block. As a result, it became possible to pave blocks that are inexpensive and very advantageous in construction and maintenance. However, if the upper body is made of synthetic resin and is paved outside, such as on the sidewalk, the feeling of landing for pedestrians is somewhat reduced, and depending on the installation location, it is not suitable for the surrounding environment. There was a problem that didn't happen.

US 10-1777216 B1

The present invention is to solve the above problems of the prior art, and improves the durability of the block pavement layer by preventing the loss of sand in the stable layer, and it is easy to manufacture and construct the block, and only the damaged block can be replaced. It is economical by reducing cost and maintenance cost, and provides a block that can prevent flooding of the pavement by improving the feeling of landing for pedestrians, quickly draining rainwater from the pavement, and securing a temporary storage space for rainwater. There is a purpose.

According to the most preferred embodiment of the present invention for solving the above problems, as having a structure in which an upper finishing block is assembled on the upper surface of the lower support block, the lower support block is formed in a square cross section made of a synthetic resin material and the lower It consists of a plurality of inlet holes penetrating up and down so that the sand of the stable layer can be inserted in the structure, and a phase coupling protrusion made of an elastic material protruding from the upper surface, and the upper closing block is a rectangular cross-section made of cement mortar, Having an upper coupling part for fixing the upper coupling protrusion of the lower support block, the upper closing block is stacked on the lower support block so as to be shifted in the diagonal direction, and the upper surface of each of the two sides of the lower support block where the upper coupling protrusion is located is exposed upward. There is provided a prefabricated composite block, characterized in that it is assembled to form a mounting surface on which the adjacent upper closing block is placed.

At this time, the upper coupling part may be configured as a locking step formed on each side by making the bottom surface area of the upper closing block larger than the upper surface area, or as a recess formed on each side side of the upper closing block and into which the phase coupling protrusion is inserted. may be In this case, the upper coupling protrusion and the upper coupling part may be configured to have an expansion and contraction gap accommodating the difference in expansion and contraction deformation between the upper coupling protrusion and the upper coupling part in the state in which the lower support block and the upper closing block are assembled.

In addition, as having a T-shape fixed to the phase coupling portion, it may be composed of a first phase coupling protrusion and a second phase coupling protrusion adjacent to each other.

In relation to the means for coupling with the adjacent lower support blocks, a flat coupling protrusion and a planar coupling recess are provided in the lower support block to correspond to each other, and a downward insertion protrusion is formed at the end of the flat coupling protrusion, and the flat coupling recess is downward. By forming an insertion groove, the downward insertion protrusion is inserted into the downward insertion groove, so that each lower support block can be coupled to each other. In this case, the flat coupling protrusion may be provided in the center of the side where the phase coupling protrusion is formed.

In addition, the planar coupling protrusions may be composed of the first planar coupling protrusions and the second planar coupling protrusions adjacent to each other, and in this case, the planar coupling recesses must also be composed of the first planar coupling recesses and the second planar coupling recesses adjacent to each other to correspond thereto. do.

On the lower surface of the lower support block, the first flat drain channel and the second flat drain channel are configured to be orthogonal to each other, so that rainwater can be quickly drained.

In addition, a +-shaped position fixing protrusion for setting the assembly position of the upper closure block may be formed on any one of the upper surface corners of the lower support block, and spaced protrusions may be formed protruding from each side of the upper closure block.

In the present invention, the following effects can be expected by assembling blocks of heterogeneous synthetic resin material and cement mortar material to form a synthetic block.

First, the lower support block made of synthetic resin located at the bottom of the synthetic block inserts some of the sand of the stabilization layer through the inlet hole and blocks the movement of sand as the bulkhead is embedded in the stabilization layer, so that the sand by the flow of rainwater during rainfall The durability of the block pavement structure is improved by preventing the loss of

Second, the construction of the composite block of the present invention is first completed in a state in which the lower support blocks are interconnected on the upper part of the sand stabilization layer, and then the upper finishing block is placed on the upper surface of the lower support block. Since the upper surface of the pre-constructed lower support block maintains a stable horizontal surface, unlike the sand layer where the flat surface may be damaged by the carelessness of the operator, it is possible to proceed with the precise construction of the upper finishing block very efficiently and quickly.

Third, since the composite block of the present invention has a structure in which the upper closing block forming the surface of the block pavement is individually coupled to the lower support block, only the destroyed upper closing block can be replaced when some upper closing blocks are damaged, so maintenance is very easy. Easy.

Fourth, the inlet formed in the lower support block forms a space of the air layer between the ground and the upper closing block to suppress the temperature rise of the upper closing block at high temperatures in summer, and the upper closing block is the lower support block made of synthetic resin exposed to sunlight to prevent spoilage.

In addition to the above effects, the composite block of the present invention induces rapid discharge of rainwater through the vertical drainage channel of the upper closing block and the first and second pyeong drainage channels of the lower support block, and the inlet of the lower support block functions as a temporary storage space for rainwater. By doing this, it is possible to expect many effects, such as preventing the block pavement from being flooded by storing some of the rainwater during rainfall.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, in the description of the present invention, in the case of obscuring or obscuring the technical idea of the present invention due to the detailed description of the known configuration, the description of the above known configuration will be omitted.

1 is a view showing a prefabricated composite block according to an embodiment of the present invention, viewed from the top and bottom, FIGS. 2 and 3 are views showing each block portion before the composite block is assembled, FIG. 2 is the synthesis The structure of the lower support block 10 constituting the lower part of the block is shown, and FIG. 3 is shown with respect to the structure of the upper closing block 20 constituting the upper part of the composite block.

The composite block of the present invention has a structure in which one upper closing block 20 is laminated and assembled on the upper surface of one lower support block 10 as shown in FIG. 1 .

More specifically, in the composite block of the present invention, the lower support block 10 and the upper closing block 20 are not manufactured or constructed in an integrated state, but first the installation process of the lower support block 10 After this is completed, as the installation process of the upper closing block 20 on the upper surface proceeds, only the lower support block 10 and the upper closing block 20 are assembled so that they are integrated.

In addition, in the synthetic block of the present invention, the upper finishing block 20 is made of cement mortar and the lower support block 10 is made of a synthetic resin material so that the advantages of each can be utilized, and their mutual relationship through the bonding structure It solves the problem caused by the difference of heterogeneous materials.

For this purpose, the lower support block 10 has a rectangular cross section, and as shown in FIG. (17) is formed.

When the synthetic block of the present invention is placed on the upper surface of the sand of the stability layer 30, the inlet hole 17 fixes the position of the synthetic block so that the position of the synthetic block does not change easily while a part of the sand is inserted, thereby improving the workability and providing excellent sand properties, etc. Even when a lateral force is generated, the sand is prevented from being moved and lost by the partition wall 16 . In addition, by functioning as a space to store rainwater during rainfall, the drainage channel not only prevents backflow, but also forms an air layer or moisture layer between the ground surface and the upper closing block 20 to increase the temperature of the block pavement surface in summer. has a deterrent function.

As shown in (a) of FIG. 2 , on the upper surface of the lower support block 10 in which the inlet hole 17 is formed, an upper coupling protrusion 14 for coupling with the upper closing block 20 is provided. .

The upper coupling protrusion 14 is made of an elastic material, and it is preferable to allow the two upper closing blocks 20 to be coupled at the same time on the upper surface of the lower support block 10. An example of a cross-sectional configuration for this is T The two upper closing blocks 20 can be fixed to the upper coupling protrusions 14 by each horizontal protrusion 141 symmetrically formed to have a ruler shape.

This phase coupling protrusion 14 is composed of a first phase coupling protrusion 14A and a second phase coupling protrusion 14B that are adjacent to each other, which are provided only on two sides adjacent to each other on the four sides of the lower support block 10, as shown in FIG. As shown in 1, it is positioned on the mounting surface 13 to be described later.

The upper finishing block 20 made of cement mortar also has a rectangular cross section like the lower support block 10 described above, and the upper coupling protrusion 14 of the lower support block 10 is fixed to each side of the four sides. A coupling portion 21 is provided.

The upper coupling portion 21 needs to be particularly limited as it is sufficient as long as it has a shape that prevents the upper closing block 20 from easily dislodging from the lower support block 10 to the upper portion by the upper coupling protrusion 14 being fixed. However, by considering the ease of construction for the installation of the upper closing block 20, the ease of maintenance, and the ease of manufacture, the packaging of the block should be economical.

In relation to the configuration of the upper coupling part 21, the upper closing block 20 shown in FIG. 3 has a locking step 211 on each side by making the bottom surface area of the upper closing block 20 larger than the upper surface area. and the horizontal protrusion 141 of the upper coupling protrusion 14 is caught and fixed to the locking step 211 .

In this way, when the upper coupling portion 21 is configured as the engaging step 211, it is possible to omit the demolding of the side formwork during the manufacturing process of the upper closing block 20. It enables the pavement construction of blocks.

Of course, as shown in FIG. 4 , the upper coupling part 21 may be configured such that the upper coupling protrusion 14 is inserted therein by forming a recess 212 on each side side of the upper closing block 20 .

FIG. 5 shows a description of a process in which the upper coupling protrusion 14 is fixed to the upper coupling part 21 when assembling the upper closing block 20 to the lower support block 10 based on the embodiment of FIG. 3 . did it

First, by inclining the upper closing block 20, one side of the engaging step 211 is inserted into the lower portion of the horizontal protrusion 141 of the upper coupling protrusion 14, and then the lower support block adjacent to the other side of the upper closing block 20 ( When the horizontal protrusion 141 of the upper coupling protrusion 14 provided in 10) is pressed, the upper coupling part 21 is bent by elastic deformation and then the horizontal protrusion 141 passes through the engaging step 211 and then again As it is restored, the horizontal protrusion 141 is caught on the locking step 211 . In this way, one upper closing block 20 is fixed by the upper coupling protrusions 14 provided in the lower support block 10 on the left or right side adjacent to the four sides and the lower support block 10 on the upper or lower side. Displacement to the upper part is prevented.

On the other hand, the lower support block 10 and the upper closing block 20 have a large difference in the rate of expansion and contraction according to the temperature change due to the material difference. Therefore, when the lower support block 10 and the upper closing block 20 have complete integrity, there is a possibility that their coupling portion may be damaged due to a difference in the rate of expansion and contraction.

Therefore, in another embodiment of the present invention, in a state in which the lower support block 10 and the upper closing block are assembled, an expansion and contraction gap ( △ ₁ , △ ₂ ) The phase coupling protrusion 14 and the phase coupling portion 21 are formed so as to be provided. 6 is a view showing a state in which the phase coupling protrusion 14 is fixed to the phase coupling part 21 while the expansion and contraction gaps Δ ₁ and Δ ₂ are maintained.

A pair of spacer protrusions 22 spaced apart from each other in the vertical direction together with the above-described upper coupling part 21 may be protruded from each side of the upper closing block 20 . Of course, when the upper coupling portion 21 is configured of the engaging step 211, the width d of the engaging step 211 should be smaller than the degree to which the spacer protrusion 22 protrudes.

The spacer protrusion 22 forms a vertical drainage channel 23 between the adjacent upper closing block 20, so that rainwater from the block pavement surface is quickly discharged, thereby not causing inconvenience to the user's walking in the rain. In addition, the spacer protrusion 22 serves as a cushioning function to prevent the upper closing blocks 20 from being damaged while colliding with each other by the lateral force in the lateral direction.

The upper closing block 20 is assembled in such a way that it is stacked so as to be shifted diagonally from the upper portion of the lower support block 10 .

In the assembled state, the lower support block 10 has the upper surfaces of two adjacent sides exposed to the upper portions to form a flat surface 13, and an adjacent upper closing block 20 is formed on the surface 13. It is fixed by the phase coupling protrusion 14 formed here while being placed. That is, as shown in (a) of FIG. 2 , the mounting surface 13 is formed only on two adjacent sides so that the upper coupling protrusion 14 is installed among the four sides of the lower support block 10 .

Therefore, the portion where the two adjacent upper closing blocks 20 abut each other is located on the flat surface of the surface 13, and thus the upper and lower portions are blocked. .

However, rainwater flowing down through the vertical drain 23 can flow into the inlet 17 through between the bottom surface of the upper closing block 20 and the upper surface of the lower support block 10 . Of course, although not shown in the drawings, the bottom surface of the upper closing block 20 or the lower support block 10 so that the rainwater flow between the bottom surface of the upper closing block 20 and the upper surface of the lower support block 10 is made more smoothly. ) may be further provided with a drain groove toward the inlet hole 17 on the upper surface.

In addition, on the lower surface of the lower support block 10, a first flat drain 18A and a second flat drain 18B are drawn in, as shown in FIGS. 1 (b) and 2 (b), respectively. By providing the ball 17 so as to communicate orthogonally to each other, rainwater introduced through the inlet hole 17 can be discharged to an external drain pipe through the first and second flat drainage channels 18A and 18B.

In the composite block of the present invention, as described above, after the installation process of the lower support block 10 is completed, the installation process of the upper closing block 20 is performed. FIGS. 7 and 8 show the lower support block 10 . As shown in relation to the installation process of each, FIG. 7 is a diagram illustrating a connection operation between each lower support block 10, and FIG. 8 shows each lower support block on the stable layer 30 of sand in this way. (10) shows a part of the completed state.

The lower support block 10 may be installed in a manner that does not have a connection structure with the adjacent lower support block 10, but preferably has a connection structure as illustrated in FIG. Blocks 10 to be able to stably maintain the correct position against the unexpected horizontal load due to the integrated behavior.

In the case of the connection structure according to the embodiment, the lower support block 10 is provided with a flat coupling protrusion 11 for coupling with the adjacent lower support block 10 and a flat coupling recessed portion 12 corresponding thereto, respectively, The planar coupling protrusion 11 and the planar coupling recess 12 are located in the center of the side on which the upper coupling protrusion 14 is formed.

The planar coupling protrusion 11 is composed of a first planar coupling protrusion 11A and a second planar coupling protrusion 11B protruding in a horizontal direction from mutually adjacent sides among the four sides of the lower support block 10, The coupling recess 12 is also composed of a first planar coupling recess 12A and a second flat coupling recess 12B adjacent to each other, so that the lower support blocks 10 can be connected in each direction of up, down, left and right.

The coupling structure of the planar coupling protrusion 11 and the planar coupling recessed part 12 may be formed in various shapes, but a downward insertion protrusion 111 is provided at the end of the planar coupling recessed part 11 and the inner side of the planar coupling recessed part 12 As shown in FIG. 7 by providing a downward insertion groove 121 into which the downward insertion projection 111 is vertically inserted, only the operation of placing the lower support block 10 in the vertical direction is sufficient for each lower support block 10. ), it is desirable to make the mutual coupling of them easy.

As described above, the upper closing block 20 is placed so as to be displaced diagonally with respect to the lower support block 10 and assembled so that at least one of the upper surface corners of the lower support block 10 has an upper closing block. A position fixing protrusion 15 for setting the position where the 20 is placed, that is, the assembly position of the upper closing block 20 may be formed.
