Description

[0001] The present invention relates to a pre-fabric panel,

The present invention relates to a pre-fabricated panel-type automatic pouring concrete block, and more particularly, to a pouring method of a prefab panel type automatic pouring concrete block, A prefabricated pipe that can stably support the connection pipe connecting the pipes and minimizes the heat loss in the connection pipe, Panel-type auto-erosion concrete block.

Due to the recent global warming, the duration of winter has been shortening for the past 80 years in Korea, but the signs of abnormal weather such as frequent snow storms are increasing. When we look at the current status of natural disasters in the last 10 years, there were 19 natural disasters in total, 15 times in heavy snowfall and 4 times in storm surge.

In winter, the damage caused by traffic disruption and congestion such as highways, national roads, and local roads caused by snowfall is happening every year. Especially, in case of sudden heavy snowfall in a short time, snow accumulates on the roads, . In addition, after the snowfall, the subzero temperature is usually maintained, and in the areas with heavy traffic such as large cities, the ice is expected in less snow. Hundreds of snowmobiles and manpower are mobilized to spray the snowmelt when the snow is predicted ought.

Therefore, in order to minimize the safety and damage of drivers and pedestrians due to surprise snowfall, which is difficult to predict every year due to climate change, the primary action is very important. Most accidents are caused by snow falling, frost or frost Therefore, it is very important to prevent icing after snowing.

In order to remove the freezing section, sea ice work is performed in such a manner that calcium chloride is sprayed on the road or a snow removing work such as a scraper is used. However, such snow removal or thawing work requires a lot of manpower, equipment, and cost. Despite such road maintenance work, the roads are frozen from time to time due to the lowering of the temperature in the winter season, resulting in a lot of trouble in the running of the pedestrians and the automobiles.

In addition, the snow remnants used for snow removal are mainly sodium chloride (NaCl) and calcium chloride (CaCl ₂ ), and the chlorine ions contained in the snow remover are subjected to freezing and thawing in the concrete exposed to the atmosphere, Thermal shock is a major cause of accelerated early deterioration. Especially, the road concrete structures affected by repeated traffic freezing and thawing by the snow removers have severe damage, and surface scaling, D-line cracking, pop-out -Out), spalling, etc., the durability of the structure is severely damaged, so that not only the snow removal cost but also the road recovery cost is added.

As a result of the implementation of the snow removal process using chloride-based snow removers, additional damage such as pollution of fruit trees, crops, and soil around the roads has occurred, so that damage caused by the use of environmentally friendly snow removers And a method of spraying an antiperspirant to prevent accumulation of snow by spraying before snowfall. However, this method is hardly used due to a high unit price.

On the other hand, there has been developed a method of reducing damages by blocking the snow removing agent through a snow melting cable capable of early response at the time of snowfall. However, the snow melting and anti-icing packaging of the electric heater method is expensive, And thus it is required to develop an environment friendly snow melting system based on new and renewable energy.

In order to solve this problem, Japanese Laid-Open Patent Publication No. 10-2014-0017366 discloses a road icing prevention system including a heat generating panel assembly having a heat ray that receives electricity from sunlight and generates heat. However, Is ineffective in the case of snowing, especially when snowfall occurs, and when soil or dust is piled up on the light-collecting surface, the efficiency is rapidly reduced and the cost efficiency is low. In addition, this is merely a means of merely releasing means for solving freezing by transmitting heat to the road surface, and there is a concern that such an electric device is difficult to maintain and repair because of a concern about breakdown such as disconnection or malfunction.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and it is an object of the present invention to provide a method and apparatus for blocking concrete, A prefab panel for enabling quick removal of snow and icing on the roads or roads and capable of stably supporting the connection pipe connecting the pipes and minimizing the heat loss in the connection pipe, Type auto-pouring concrete block.

In order to achieve the above object, the present invention provides an upper concrete layer 10 formed of thermally conductive concrete; A pipe 20 inserted into the upper concrete layer 10 to provide a path through which the fluid can flow, and having an inlet and an outlet exposed to an outer surface of the upper concrete layer 10; The upper concrete layer 10 is provided in the lower part of the upper concrete layer 10 and has the same area as the upper concrete layer 10, A lower concrete layer (30) on which an extension part (32) protruding in a longitudinal direction is formed; The other end of the connection pipe 42 is connected to an outlet or an inlet of the pipe 20 formed in the adjacent upper concrete layer 10 and is connected to the inlet or the outlet of the pipe 20 at one end, A supporting block 40 on which the upper and lower sides are inserted and seated; A water permeable block 50 having an area corresponding to the area of the extension part 32 and a height equal to the height of the upper concrete layer 10 and formed with an insertion groove 51 into which the support block 40 is inserted, The present invention also provides a prefab panel-type automatic pouring concrete block comprising:

At this time, the upper and lower support blocks 41 and 42 are formed of a material having a warming property or a block having a heat insulating property.

In addition, the upper concrete layer 10 and the lower concrete layer 30 are coupled to each other by projections and grooves.

A discharge hole 34 communicating with the paper 2 is further formed on the extension 32 so as to facilitate discharge of the fluid flowing through the water-permeable block 50.

In addition, the water-permeable block 50 is formed to have a protrusion and a groove structure mutually coupled to one surface of the facing surface of the upper concrete layer 10 and the lower concrete layer 30.

In addition, the upper surface of the upper concrete layer 10 is formed with a gradient S that gradually decreases in a direction in which the water-permeable block 60 is coupled.

The prefab panel-type auto-pouring concrete block according to the present invention has a structure in which the concrete forming the guide or the driveway is blocked and is easy to be transferred and installed. Since the block is installed and thus the block is broken or damaged, It is possible to replace or repair only the block without replacing the road and the roadway as a whole, thereby reducing maintenance period and maintenance cost.

In addition, since one automatic pouring concrete block is also modularized into an upper concrete layer, a lower concrete layer and a permeable block, it is possible to replace or repair only the corresponding module in which each module is damaged or broken. Since the high-temperature fluid flows and the heat is transferred, it is possible to automatically remove the snow or ice formed on the road automatically without any additional apparatus or personnel, and in the summer, the low temperature fluid flows through the pipe, It is possible to prevent the temperature from rising above the temperature.

Further, by stably supporting the connection pipe connecting the pipes installed between the adjacent blocks, it is possible to protect the connection pipe from external impact or pressurization, and the heat loss in the connection pipe can be reduced.

Also, it is possible to minimize the heat loss by minimizing the time for the fluid flowing from the outside through the gradient of the upper concrete block, the permeable block and the discharge hole to stay on the automatic block concrete block.

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

The present invention relates to a method and a device for blocking a concrete that forms a roadway or a roadway and facilitating the transportation, field assembly and installation, and when a high temperature fluid is flowed through a piping provided therein, The present invention relates to a prefab panel-type auto-snow removal concrete block capable of stably supporting a connection pipe connecting pipes and minimizing heat loss in a connection pipe, The piping 20 in the upper concrete layer 10, the lower concrete layer 30, the connecting pipe 50, the supporting blocks 41 and 42 of the connecting pipe 50 and the water permeable block 60 .

The upper concrete layer 10 forms an upper surface of a road such as a roadway or a sidewalk and receives heat of hot fluid flowing through the piping 20 inserted therein when snow or ice occurs in the winter season, ) This is a structure for melting snow on the upper surface or melting ice. Accordingly, it is preferable that the upper concrete layer 10 is made of a thermally conductive concrete so as not to be easily broken when a person or a vehicle is traveling, and to transmit the heat of the fluid flowing in the pipe 20 to the upper surface quickly.

5, the upper surface of the upper concrete layer 10 is formed in the upper concrete layer 10 in order to prevent the generated fluid or the fluid flowing from the outside from flowing into the upper concrete layer 10 due to snowfall or icing, It is preferable to form the gradient S that gradually decreases in the direction in which the water-permeable block 60 described later is combined. In this case, although the angle of the gradient S is exaggerated in order to clarify the features of the present invention, in the actual use, the obstacle does not occur during passage of a person or vehicle, and the fluid flowing on the upper portion of the upper concrete layer 10 So that the gradient S is formed at an angle corresponding to the angle.

The pipe 20 is inserted into the upper concrete layer 10 as shown in FIGS. 1 and 6 to provide a path through which the high temperature fluid supplied from the heat source 70 can flow, And may be arranged in various forms inside the concrete layer 10. The inlet and the outlet of the pipe 20 through which the fluid flows may be exposed to the outer surface of the upper concrete layer 10 so as to be uniformly distributed over the entire surface of the upper concrete layer 10, . In FIG. 1, the inlet and the outlet of the pipe 20 are formed on the same surface of the upper concrete layer 10, but may be exposed in different directions according to the usage.

The lower concrete layer 30 is provided at the lower portion of the upper concrete layer 10 to support the lower concrete layer 30 to minimize the heat transfer from the pipe 20 to the downward direction and to maximize the upward flow rate with respect to the pipe 20 And to minimize the downward heat flux. For this purpose, the lower concrete layer 30 is preferably made of concrete having a lower thermal conductivity than the upper concrete layer 10.

The upper concrete layer 10 and the lower concrete layer 30 are formed to have a protrusion and a groove structure and are coupled to each other so that the upper concrete layer 10 can be separated from the lower concrete layer 30, The coupling strength for maintaining the initially engaged position is improved.

1 and 2, the lower concrete layer 30 has the same area as that of the upper concrete layer 10, and the upper concrete layer 10 has an inlet or an outlet of the pipe 20 exposed. An extension portion 32 protruding by a predetermined length in the lateral direction is integrally formed. 4, when the plurality of auto-erosion concrete blocks are continuously disposed, the expansion pipe 32 is connected to the outside of the connecting pipe 50 for interconnecting the pipes 20 provided in the respective auto- To provide a space in which the water-permeable block (60) can be seated on the upper portion of the pipe (20) to prevent heat loss from being exposed.

At this time, an exhaust hole 34 communicating with the paper 2 is further formed on the extension 32 so that the fluid flowing through the water-permeable block 60 can be easily discharged. This minimizes the permeation of the external fluid into the inside of the auto-erosion concrete block through the top surface of the upper concrete layer 10, the permeable block 60 and the discharge hole 34 in order, Can be maximized.

One end of the connecting pipe 50 is connected to the inlet or the outlet of the pipe 20 and the other end is connected to the outlet or inlet of the pipe 20 formed in the adjacent upper concrete layer 10.

The inlet and the outlet of the pipe 20 are exposed in the same direction so that the expansion portion 32 is formed only on one side of the lower concrete layer 30. In another embodiment, The extensions 32 may be formed in respective directions in which the inlet and the outlet of the pipe 20 are exposed.

The connection pipe 50 is provided on the outer side of the upper concrete layer 10 and is surrounded by the water permeable block 60. However, since a space is formed around the connection pipe 50, unexpected external force There is a risk of being damaged or damaged by a strong impact and a close contact structure with the connection pipe 50 for minimizing the heat loss of the connection pipe 50 which can not be completely solved only by the water permeable block 60 is required .

2 and 5, the support blocks 41 and 42 are provided on the upper and lower sides of the connection pipe 50, respectively. At this time, the upper and lower support blocks 41 and 42 correspond to the upper and lower sides of the connection pipe 50, respectively, so that the connection pipe 50 is inserted into the groove so that the connection pipe 50 can be stably supported And the upper and lower support blocks 41 and 42 are preferably formed of a material having thermal insulation or a block having thermal insulation.

The support blocks 41 and 42 surround the outer surface of the connection pipe 50 and are brought into close contact with the lower concrete layer 30 at the lower side and are brought into close contact with the upper concrete layer 10 at one side, It is possible to prevent the connection pipe 50 from being damaged due to external impact or pressure.

The water-permeable block 60 is formed to have the same height as the area of the extension portion 32 of the lower concrete layer 30 and the height of the upper concrete layer 10, At this time, insertion grooves 61 are formed on both sides of the support blocks 41 and 42 so as to tightly enclose the support blocks 41 and 42 which are seated on the extension part 32.

The water-permeable block 60 is provided on either the upper or lower concrete layer 10 and the lower concrete layer 20 such that the upper and lower concrete layers 10, Protrusions and grooves, so that it is possible to prevent the position of the water-permeable block 60, which is coupled to the upper surface of the expanding portion 32, from being changed when the vehicle or the vehicle is traveling.

The water-permeable block 60 may be provided in a separate block state, such as an upper concrete layer 10 and a lower concrete layer 20, and may be assembled and formed into a shape on the expansion portion 32 , And pervious concrete is poured and cured on the surface.

The above-described prefab panel-type auto-pouring concrete block according to the present invention calculates the area of the guide or roadway to be used and determines its size. Referring to FIG. 6, the concrete block is closely disposed so as to correspond to the area of the guide or the roadway, and the upper concrete layer 10 and the lower concrete layer 30 are disposed preferentially.

Next, the pipe 20 of each concrete block is connected to the connection pipe 50 and the supply pipe and the return pipe of the heat source 70. Finally, while the connection pipe 50 exposed to the outside is protected, The upper and lower portions of the connection pipe 50 are wrapped by the support blocks 41 and 42 to minimize the heat loss of the fluid flowing through the lower concrete layer 30 and the lower concrete layer 30, (60) corresponding to the area of the water-permeable block (32).

In the prefab panel-type automatic snow-remained concrete block according to the present invention, when the snow or ice occurs in the winter season, the high temperature fluid is supplied from the heat source 70 to allow the high temperature fluid to flow to the pipe 20, The piping 20 conveys the heat generated by the high temperature fluid to the upper concrete layer 10. Since the upper concrete layer 10 is made of a material having relatively high thermal conductivity as compared with the lower concrete layer 30, the heat generated in the pipe 20 maximizes the upward heat flux, minimizes the downward heat flux, Can be maximized.

As described above, the snow or ice formed on the upper concrete layer 10 is automatically melted through the heat transfer of the hot fluid flowing through the pipe 20, so that the passage of the pedestrian or the vehicle can be smoothly performed.

At this time, the fluid generated by snow melting or freezing flows to the side of the water-permeable block 60 along the gradient S of the upper concrete layer 10, and the fluid flowing downward through the water- It is possible to maximize the heat transfer efficiency through the pipe 20 by minimizing the time required for the fluid to quickly pass through the discharge hole 34 formed in the expansion portion 32 of the concrete layer 30 to the outside so as to allow the fluid to stay in the concrete block .

Conversely, during the summer, when the temperature of the delivery or driveway rises excessively, the low temperature fluid can be passed through the pipe 20 to lower the temperature of the delivery or driveway.
