Description
TECHNICAL FIELD
[0001] The present invention relates to a pre-fabricated sidewalk
block, and more particularly, to a pre-fabricated sidewalk block
having a heating wire, which efficiently transmits to an upper
portion of a sidewalk block without losing heat radiated from the
heating wire to the ground, is easily assembled, and absorbs an
impact during the walking.
BACKGROUND ART
[0002] In general, sidewalk blocks are blocks in which block-shaped
plates are covered on the road surface for sidewalk to prevent soil
from being lost or damaged and to allow the pedestrians to
comfortably go walking. Here, the blocks having the same shape are
continuously installed along the sidewalk of the road.
[0003] Cement blocks manufactured by mixing sand, cement, and
pigment are mainly used as the conventional sidewalk blocks.
However, the cement blocks may be hard to apply an impact to the
sole or ankle of the pedestrian.
[0004] In recent years, sidewalk blocks manufactured using waste
plastic or waste tires have been installed to mitigate the impact
applied to the pedestrians.
[0005] Since the conventional sidewalk blocks are relatively
smooth, if the surfaces of the sidewall blocks are covered with
snow or frozen in winter, the pedestrians may slip to cause
injury.
[0006] Thus, in order to ensure the safety of pedestrians in
winter, calcium chloride may be sprayed on the sidewalk blocks to
perform a de-icing operation, or heating wires may be installed
under the sidewalk blocks to remove the snow or frost on the
sidewalk blocks.
[0007] However, in the case where the heating wires are installed
under the conventional sidewalk blocks, heat generated from the
heating wires may not be transferred to the upper portions of the
sidewalk blocks, but be absorbed into the ground. In addition,
since the heating wires are installed between the sidewalk blocks
and the ground, the hating wires may be damaged.
DISCLOSURE OF THE INVENTION
Technical Problem
[0008] An object of the present invention is to provide a
pre-fabricated sidewalk block having a heating wire, in which a
groove part is defined in a top surface of a lower block, a groove
part protruding downward to correspond to the groove of the lower
block is defined in a buffer plate, a protrusion part protruding
downward so that the protrusion part is inserted into the groove
part of the buffer plate is disposed on an upper block, a heating
wire insertion groove is defined between a top surface of the
buffer plate between the groove parts of the buffer plate and a
bottom surface of the upper block between the protrusion parts of
the upper block to successively stack and assemble the lower block,
the buffer plate, the heating wire, and the upper block.
[0009] Another object of the present invention is to provide
pre-fabricated sidewalk block having a heating wire, in which a
buffer plate having an insulation function is disposed between a
lower block and an upper block, and the heating wire is disposed
between the buffer plate and the upper block to prevent heat
radiated from the heating wire from being lost into the ground.
[0010] Another objection of the present invention is to provide
pre-fabricated sidewalk block having a heating wire, in which each
of circumferences of groove parts of a lower block, a buffer plate,
and an upper block has an inclined plane to disperse a load.
Technical Solution
[0011] According to an aspect of the present invention, there is
provided a pre-fabricated sidewalk block having a heating wire, the
pre-fabricated sidewalk block including: a lower block including a
plurality of first groove parts in a top surface thereof; a buffer
plate including a plurality of second groove parts protruding
downward so that the plurality of second groove parts are inserted
and coupled into the first grove parts of the lower block, the
buffer plate having a first heating wire insertion groove in a
length direction in a top surface thereof between the second groove
parts; an upper block comprising a plurality of protrusion parts
protruding downward so that a bottom surface of the upper block is
inserted and coupled to the second groove parts of the buffer
plate, the upper block having a second heating wire insertion
groove corresponding to the first heating wire insertion groove in
a bottom surface thereof between the protrusion parts adjacent to
each other; and a heating wire inserted between the first heating
wire insertion groove and the second heating wire insertion
groove.
[0012] Each of circumferences of the first and second groove parts
may have an inclined plane, and the buffer plate may be formed of a
silicon or PVC material.
[0013] Ends of the first heating wire insertion grooves adjacent to
each other and ends of the second heating wire insertion grooves
adjacent to each other may be connected to each other through a
curved insertion groove.
[0014] The upper block may have a thickness of about 150 mm to
about 250 mm.
Advantageous Effects
[0015] According to the present invention, since the groove part of
the buffer plate and the protrusion part of the upper block are
successively inserted, stacked, and coupled into the groove part
defined in the top surface of the lower block, the pre-fabricated
sidewalk block may be easily assembled. Also, the buffer plate may
be disposed between the upper block and the lower block to prevent
the upper and lower blocks from being damaged due to the impact
therebetween and reduce the impact applied to the pedestrian. Also,
the heat radiated from the heating wire may be blocked by the
buffer plate to prevent the heat from being lost into the ground
through the lower block, thereby efficiently transferring the heat
toward the top surface of the upper block and increasing de-icing
efficiency.
[0016] Also, each of the circumferences of the groove parts of the
lower block and the buffer plate may have the inclined plane to
disperse the load, thereby preventing the pre-fabricated sidewalk
block from being damaged due to the excessive load, and thus
increasing the replacement period of the sidewalk block.
BRIEF DESCRIPTION OF THE DRAWINGS
[0017] FIG. 1 is a plan view of a pre-fabricated sidewalk block
including a heating wire according to the present invention.
[0018] FIG. 2 is an exploded cross-sectional view of the
pre-fabricated sidewalk block including the heating wire according
to the present invention.
MODE FOR CARRYING OUT THE INVENTION
[0019] Example embodiments of the present invention will now be
described more fully hereinafter with reference to the accompanying
drawings.
[0020] FIG. 1 is a plan view of a pre-fabricated sidewalk block
including a heating wire according to the present invention, and
FIG. 2 is an exploded cross-sectional view of the pre-fabricated
sidewalk block including the heating wire according to the present
invention.
[0021] Referring to FIGS. 1 and 2, a pre-fabricated sidewalk block
including a heating wire according to the present invention
includes a lower block 1, a buffer plate 2, an upper block 3, and a
heating wire 4.
[0022] Here, the lower block 1 is installed on the ground. Also, a
plurality of first groove parts 11 are defined in a top surface of
the lower block 1. Here, each of the first groove parts 11 may have
an inclined plane having a predetermined inclined angle on a
circumference thereof. That is, since the circumference of the
first groove part 11 has the inclined structure, when a load of a
pedestrian is applied to the sidewalk block after the lower block 1
is assembled with the upper block 3 that will be described later in
detail, the load may be dispersed in the inclined direction without
being applied in a direction perpendicular to the ground to prevent
the sidewalk block from being damaged due to the excessive
load.
[0023] The buffer plate 2 may be coupled between the lower block 1
and the upper block to prevent the lower block 1 and the upper
block 3 from being damaged due to collision therebetween. Also, the
buffer plate 2 may mitigate an impact applied to the pedestrian and
protect the heating wire 4. A plurality of second groove parts 21
in which the first groove parts 11 are inserted and coupled are
defined in the buffer plate 2 to protrude downward.
[0024] Also, a plurality of first heating wire insertion grooves 22
each extending in a length direction of the buffer plate 2 and
having a semicircular shape are defined in top surfaces of the
buffer plate 2 between the second groove parts 21, respectively.
Also, first curved insertion grooves connecting ends of the
adjacent first heating wire insertion grooves 22 to each other are
defined in front and rear ends of the buffer plates 2. As described
above, since each of the first curved insertion grooves 23 connects
the adjacent first heating wire insertion grooves 22 to each other,
the heating wire may be inserted in a smoothly curved shape without
being bent at the front and rear ends of the buffer plates 2.
[0025] Also, since the buffer plate 2 is formed of a silicon or PVC
material, the buffer plate 2 may insulate heat radiated from the
heating wire 4 to prevent the heat from being transferred to the
ground through the lower block 1, thereby improving heat transfer
efficiency into the upper block 3.
[0026] The upper block 3 may provide a surface layer contacting
foots of the pedestrian. A plurality of protrusion parts 31
inserted and coupled into the second groove parts 21 protrude
downward from a bottom surface of the upper block 3.
[0027] Also, second heating wire insertion grooves 32 each
extending in a length direction of the upper block 3 and having a
semicircular shape are defined in the bottom surfaces of the upper
block 3 between the protrusion parts 31, respectively. Here, each
of the second heating wire insertion grooves 32 may have a shape
corresponding to that of each of the first heating wire insertion
grooves 22. Thus, when the upper block 3 is assembled with an upper
portion of the buffer plate 2, the first and second heating wire
insertion grooves 22 and 32 define a circular groove so that the
heating wire is inserted therein.
[0028] Also, like the buffer plate 2, second curved insertion
grooves 33 connecting ends of the adjacent second heating wire
insertion grooves 32 to each other may be defined in front and rear
ends of the upper block 3. That is, since each of the second curved
insertion grooves 33 connects the adjacent second heating wire
insertion grooves 32 to each other, the heating wire may be
inserted in a smoothly curved shape without being bent at the front
and rear ends of the upper block 3.
[0029] The upper block 3 may have a thickness of about 150 mm to
about 250 mm. That is, if the upper block 3 has a thin thickness,
the heat radiated from the heating wire 4 may be well transferred
to well melt snow and froze on the upper black 3. However, the
heating wire may be damaged by the load or an external impact and
thus be exposed to the outside. On the other hand, if the upper
block 3 has a thick thickness, the heat radiated from the heating
wire 4 may not be well transferred up to the top surface of the
upper block 3, and thus, the snow or frost may not be well molten.
Thus, the upper block 3 may have a thickness of about 150 mm to
about 250 mm, particularly, a thickness of about 200 mm.
[0030] Hereinafter, a process of assembling the pre-fabricated
sidewalk blocks including the heating wire according to the present
invention will be described with reference to FIGS. 1 and 2.
[0031] First, the second groove part 21 defined in the bottom
surface of the buffer plate 2 to protrude is inserted into the
first groove part 11 defined in the top surface of the lower block
1 to stack the buffer plate 2 on the lower block 1.
[0032] Also, the heating wire is inserted into the first heating
wire insertion groove 22 and the first curved insertion groove 23
which are defined in the top surface of the buffer plate 2.
[0033] Then, the protrusion part 31 protruding from the bottom
surface of the upper block 3 is inserted into the second groove
part 21 of the buffer plate 2 to stack and couple the upper block 3
on the buffer plate 2. Here, when the buffer plate 2 and the upper
block are stacked and assembled with each other, an upper portion
of the heating wire 4 inserted into the first heating wire
insertion groove 22 is inserted into the second heating wire
insertion groove 32.
[0034] As described above, the protrusion part having a shape
corresponding to the first groove part 11 defined in the top
surface of the lower block 1 and protruding from the bottom surface
of the upper block 3 may be stacked on the bottom surface of the
buffer plate 2. Therefore, the upper block 3, the buffer plate 2,
and the lower block 1 may be easily assembled with each other.
[0035] Although the present invention is described with respect to
the above-described exemplary embodiment, various modifications and
variations can be made in the present invention without departing
form the spirit or scope of the invention. Thus, the spirit and
scope of the present invention defined by the following claims may
include the modifications and variations belonging to subject
matters of the present invention.
