The rail clamp 1 according to an embodiment of the present invention allows the rail 4 to be easily transported to the construction site (installation site), and will hereinafter be referred to as the ‘bone clamp’ for convenience of explanation.

Referring to Figure 1, this clamp (rail clamp (1) according to an embodiment of the present invention) includes a first locking link (11) and a second locking link (12).

The first locking link 11 includes a first vertical portion 111, a first inclined portion 112 extending upwardly from the top of the first vertical portion 111, and a lower portion of the first vertical portion 111. It includes a first locking portion 113 that protrudes forward from the front side.

Here, the upper side (top, top, etc.) means the upper side (top, top, etc.) with respect to FIG. 1, and the lower side (lower, bottom, etc.) means the lower side (lower, bottom, etc.) with respect to FIG. 1. Additionally, the vertical direction refers to the vertical direction with respect to FIG. 1. The same will be applied in the description below.

In addition, the front (front end, etc.) described above refers to the right direction (right end, etc.) with respect to FIG. 1, and the rear (rear end, etc.) described later refers to the left direction (left end, etc.) with respect to FIG. 1. Hereinafter, The same will be applied in the explanation.

The second locking link 12 is a second vertical part 121 disposed ahead of the first vertical part 111, extends upwardly and inclined backward from the top of the second vertical part 121, and is connected to the first inclined part 121. It includes a second inclined portion 122 jointly coupled with 112 and a second locking portion 123 protruding rearward from the lower rear of the second vertical portion 121.

1 is a front view of the above-mentioned main clamp, and the second locking link 12 may be illustratively disposed on the rear side of the first locking link 11, and the first locking link 11 ) and the second locking link 12, each of the first inclined portion 112 and the second inclined portion 122 are arranged along the front-back direction, and when viewed from the front, the first inclined portion 112 and The second inclined portion 122 is crossed, and the first inclined portion 112 and the second inclined portion 122 are jointed so that the first engaging link 11 and the second engaging link 12 can be coupled to each other. there is.

As described above, the first inclined portion 112 and the second inclined portion 112 are jointed, and the first engaging link 11 and the second engaging link 12 use the jointed portion as the central axis. It can be rotated, and therefore the separation distance between the first and second locking parts 113 and 123 can be adjusted.

With the first locking link 11 and the second locking link 12 rotated so that the first locking part 113 and the second locking part 123 are separated from each other, the main clamp is moved toward the rail (4). moves (moves downward), and then the first locking link 11 and the second locking link 12 are rotated so that the first locking part 113 and the second locking part 123 are closer to each other. The upper portions of the first engaging portion 113 and the second engaging portion 123 may support the rail 4.

Exemplarily, the above-mentioned locking parts support the lower part of the rail 4, or as another example, when the rail 4 has a shape such as an H-beam, the first locking part 113 and the second locking part 123 The upper part of can support the lower part of the flange of the rail (4).

Afterwards, the main clamp can be connected to a separate device and the main clamp can be moved to easily transport the rail (4) to the construction site. During the transport process, the rail 4 presses the upper parts of the first and second locking parts 113 and 123 downward, so that the first and second locking links 11 and 12 rotate. The rail 4 can be transported to the construction site while maintaining the separation distance between the first locking portion 113 and the second locking portion 123. That is, the rail 4 may not be dropped during transportation.

At this time, when the second locking portion 123 protrudes backward from the lower rear of the second vertical portion 121, it protrudes to be curved backward. To be more specific, the second locking portion 123 may protrude at a downward angle from the lower rear portion of the second vertical portion 121 and may protrude curved backward (or curved downward backward).

Likewise, the first locking portion 113 may also protrude curved forward from the lower front of the first vertical portion 111. To be more specific, the first vertical portion 111 may protrude downwardly from the lower portion forward and curved forward (or curved forward downward).

Through this, damage to the rail (4) of this clamp can be minimized by minimizing wear and damage to the rail (4) and the locking parts that come in contact with the rail (4). In the process of opening the locking parts with your fingers, the angle of the locking parts is reduced. By minimizing the parts, workers can be prevented from getting hurt.

Referring to FIG. 1, this clamp may include a first installation link 13 having a first locking hole 131 formed in the front and a first connecting hole 132 formed in the rear.

The first center line connecting the centers of the first locking hole 131 and the first connecting hole 132 may be inclined upward toward the front (as shown in FIG. 1, this clamp moves the rail 4 upward). (based on lifted condition).

This clamp may include a second installation link 14 formed with a second engaging hole 141 coupled to the first engaging hole 131 at the rear and a second connecting hole 142 formed at the front.

The second installation link 14 may be disposed on a rear side of the first installation link 13.

As shown in FIG. 1, the first locking hole 131 and the second locking hole 141 are penetrated by the coupling part 2 (exemplarily a locking ring) of the device, which will be described later, and are connected to the first installation link 13 and the second locking hole 141. The second installation links 14 may be coupled to each other so as to be rotatable.

The second center line connecting the center of the second locking hole 141 and the center of the second connecting hole 142 may be inclined upward toward the rear.

At this time, the first locking link 11 may include a first front hole 114 formed on the front side of the first inclined portion 112 and jointly coupled with the second connection hole 142.

The first front hole 114 may be disposed on the rear side (based on FIG. 1) than the second connection hole 142, and the pin may be connected to the second connection hole 142 and the first front hole ( The first locking link 11 and the second installation link 14 extending through 114) may be rotatably coupled.

Additionally, the first locking link 11 may include a rear hole 115 formed on the first inclined portion 112 and disposed rearward than the first front hole 114.

The second locking link 12 may include a second rear hole 124 formed on the rear side of the second inclined portion 122 and jointly coupled with the first connection hole 132.

The second rear hole 124 may be disposed on the rear side of the first connection hole 132. The pin penetrates the second rear hole 124 and the first connection hole 132, so that the second rear hole 124 and the first connection hole 132 are jointed, and thus the second locking link 12 and The first installation link 13 can be rotatably coupled.

In addition, the second locking link 12 is formed on the second inclined portion 122, is disposed on the front side of the second rear hole 124, and is a second front hole jointly coupled with the first rear hole 115. It may include (125).

The second front hole 125 may be disposed on the rear side of the first rear hole 115, and similarly, the pin may pass through the second front hole 125 and the first rear hole 115. The second front hole 125 and the first rear hole 115 are jointly coupled, and the first locking link 11 and the second installation link 14 can be rotatably coupled.

In this way, this device includes a first installation link 13 including a first engaging hole 131 and a second installation link including a second engaging hole 141 engaged with the first engaging hole 131. By including (14), there is an advantage that the main clamp can be transported through one hook (coupling portion (2) described later).

As described above, the upper portions of the locking portions are pressed downward by the rail 4. Accordingly, the first locking link 11 and the second locking link 12 are maintained in a state in which they do not rotate with each other.

Afterwards, the above-described locking ring pulls the front of the first installation link (13) upward and the rear of the second installation link (14) upward to raise the first locking link (11) and the second locking link (12). In this case, the front side of the above-described first installation link 13 rotates around the first connection hole 132 as the central axis, so that the front rotates counterclockwise with respect to FIG. 1 and moves upward, and the second installation link (14) The rear side rotates clockwise with respect to the second connection hole 142 and moves upward.

In this state, the height of the rail 4 can be maintained and the rail 4 can be transported to the construction site.

When the above-described rail (4) is later placed on the floor of the construction site, when the above-described engaging ring moves downward to approach the floor side, the rear of the first installation link (13) becomes the above-described second engaging link. The rear of the inclined portion 122 of the link 12 is pressed downward, and the front of the second installation link 14 presses the front of the first locking link 11 downward.

Then, the first locking link 11 rotates clockwise with the first rear hole 115 as its central axis (based on the clamp seen from the front as shown in Figure 1), and the second locking link 11 By rotating the link 12 and the first rear hole 115 as the central axis in a counterclockwise direction, the distance between the first locking part 113 and the second locking part 123 is automatically widened, and the rail It can be separated from (4).

In other words, the main clamp and the rail 4 can be separated without the operator having to apply force to spread the first locking portion 113 and the second locking portion 123.

Hereinafter, a rail transfer device (T) (hereinafter referred to as ‘this device’) according to an embodiment of the present invention will be described. Since this device includes the above-described main clamp and includes the same or corresponding technical features as the above-described main clamp, the same reference numerals are used for the same or similar configurations as the above-described configurations, and overlapping descriptions are simplified or Decided to omit it.

Referring to Figure 2, the device includes a bone clamp, a coupling portion (2), and a conveying portion (3).

The coupling portion 2 is detachably connected to the locking link 11 and the second locking link 12.

The coupling portion 2 may exemplarily include a locking ring, and the first locking hole 131 of the first installation link 13 and the first locking hole 131 of the second installation link 14 are described above. The first installation link 13 and the second installation link 14 can be detachably coupled to each other by penetrating through the two locking holes 141 at the same time.

It has been described above that each of the above-described first installation link 13 and the second installation link 14 is connected to each of the above-described second engaging link 12 and the first engaging link 11.

The transfer unit 3 is connected to the coupling unit 2 and includes a caster.

Exemplarily, the coupling portion 2 may include the locking ring, a link disposed above the locking ring, and a chain whose lower end is connected to the locking ring and an upper end connected to the locking ring.

At this time, the transfer unit 3 includes a horizontal frame, a loop portion provided at the bottom of the horizontal frame and on which the connection ring is hung, a vertical frame provided to protrude downward from the end of the horizontal frame, and a caster provided at the bottom of the vertical frame ( (moving wheels) may be included.

Meanwhile, the first locking link 11 may include a waterproofing material (GS) and a functional additive (G) applied to the outer surface of the first inclined portion 112.

The waterproofing material (GS) is applied to the outer surface of the first inclined portion 112 and may contain 5 parts by weight of urethane (compared to 0.1 part by weight of polyurethane foam, which will be described later). The waterproofing material (GS) includes urethane and adds waterproofing properties to the above (112).

Referring to Figure 3, the functional additive (G) includes a first cushioning material (G1) containing 0.1 part by weight of polyurethane foam; An inner covering material (G2) containing 0.1 part by weight of polypropylene relative to 0.1 part by weight of the polyurethane foam and surrounding the first cushioning material (G1); An outer shell material (G3) that includes 0.1 part by weight of latex and surrounds the inner shell material (G2), is fibrous, and is mixed with the waterproofing material (GS); A second cushioning material (G4) containing 0.2 parts by weight of tetradecane and disposed between the inner shell material (G2) and the outer shell material (G3); A plurality of posts (G5) containing 0.1 part by weight of aluminum and provided on the outside of the outer shell material (G3); A plurality of coupling members (G6) containing 0.1 part by weight of styrene butadiene rubber and provided on the outside of each of the plurality of posts (G5), the width of which decreases toward the outside; An anionic polymer material (G7) containing 0.1 part by weight of p-styrenesulfonic acid (SSNa) and provided on either end of the outer shell material (G3); and a cationic material (G8) that includes 0.1 part by weight of polyethyleneimine and is provided on the other end of both ends of the outer shell material (G3).

The weight parts of the functional additives (G) such as polypropylene, latex, tetradecane, aluminum, styrene butadiene rubber, p-styrenesulfonic acid, polyethylene imine, etc. are described based on 0.1 parts by weight of the polyurethane foam.

As described above, the first cushioning material (G1) includes polyurethane foam and is disposed inside the inner shell material (G2), which will be described later. Polyurethane foam is used in various fields and is porous, so it was used as a functional additive (G) to add cushioning and sound insulation.

It is preferable that the above-described polyurethane foam contains 0.1 part by weight. If it is less than 0.1 part by weight, the above-mentioned cushioning and soundproofing effects cannot be sufficiently expected, and if it exceeds 0.1 part by weight, there is a risk of the inner shell material (G2), which will be described later, bursting and leaking from the inner shell material (G2).

The inner shell material (G2) described above is disposed inside the outer shell material (G3), which will be described later, and includes 0.1 part by weight of polypropylene as described above, and surrounds the first cushioning material (G1).

If the polypropylene is less than 0.1 part by weight, it may not sufficiently surround the first cushioning material (G1), and there is a risk that the first cushioning material (G1) may be lost. If it exceeds 0.1 part by weight, the weight of the functional additive (G) may be excessive. It can be improved.

The polypropylene is manufactured in the form of a film and can be wrapped around the first cushioning material (G1) by heat fusion or the like. That is, the first cushioning material (G1) may be disposed inside the inner skin material (G2).

The outer shell material (G3) is a stretchable material containing 0.1 part by weight of latex, and may be fibrous while surrounding the inner shell material (G2) (the inner shell material (G2) and the second cushioning material (G4) described later). The outer covering material (G3) described above is mixed with the waterproofing material (GS) described above.

Since the above-mentioned outer covering material (G3) is fibrous, it can add toughness to the functional additive (G).

As will be explained in more detail in the following description, the second cushioning material (G4) is disposed between the outer shell material (G3) and the inner shell material (G2). Accordingly, the outer shell material (G3) wraps the second cushioning material (G4). If the latex is less than 0.1 part by weight, there is a risk that the second cushioning material (G4) may be lost because it cannot sufficiently surround the second cushioning material (G4), and if it exceeds 0.1 part by weight, the own weight of the functional additive (G) If it is excessively increased, the dispersibility of the functional additive (G) may be reduced.

The second cushioning material (G4) contains 0.2 parts by weight of tetradecane and is disposed between the inner shell material (G2) and the outer shell material (G3).

Tetradecane is a phase change material (PCM) with a melting point of about 4~6℃.

A phase change material is an energy storage material that can actively store and release heat without external factors in the form of latent heat without a change in temperature when the phase changes depending on the surrounding temperature.

In general, latent heat, which is heat that enters and exits without a temperature change when a phase change occurs, has a significantly higher amount of heat than sensible heat, which is heat that enters and exits with a temperature change without accompanying a phase change. This feature can be used to store high amounts of thermal energy or maintain temperature.

The second buffer (G4) described above includes, in addition to tetradecane, undecane, dodecane, tridecane, pentadecane, hexadecane, It may further include one or more of heptadecane, octadecane, nonadecane, eicosane, and triacontane. The melting point of the second buffer (G4) can be adjusted within the range of 1 to 30°C, which is room temperature.

The second cushioning material (G4) can surround the inner shell material (G2) in a solid state and can be accommodated inside the outer shell material (G3). The latex can be wrapped around the solid second cushioning material (G4) on a sheet and fixed by various known methods such as adhesive or fusion (thermal fusion) to wrap the second cushioning material (G4).

The first buffer G1 described above may contract or expand as the temperature changes. In particular, the volume of air accommodated in the pores may also contract or expand. When the above-mentioned first cushioning material (G1) is contracted, the cushioning effect for alleviating shock is reduced.

At this time, the second buffer material (G4) supplies latent heat to the first buffer material (G1), thereby suppressing heat shrinkage of the second buffer material (G4), thereby suppressing a decrease in the buffering properties of the second buffer material (G4). .

In addition, as the second cushioning material (G4) absorbs external heat, the first cushioning material (G1) expands as the temperature increases, thereby damaging the inner shell material (G2) and preventing it from being discharged to the outside.

As described above, the second buffer (G4) has a melting point of 4 to 6°C, so it can prevent the waterproofing material (GS) from falling below 0°C and prevent condensation from forming, and the waterproofing material (GS) can prevent thermal expansion or By suppressing heat shrinkage, the waterproofing material (GS) can be prevented from becoming wrinkled or cracked.

The second buffer (G4) described above is preferably disposed outside the first buffer (G1). Since the first buffer (G1) has insulation performance, the second buffer (G4) is positioned outside the first buffer (G1). ) When placed on the inside, it is difficult to expect the above-mentioned effect because heat exchange between the waterproofing material (GS) and the second buffering material (G4) is hindered.

As described above, the second buffer (G4) contains 0.2 parts by weight of tetradecane. If it is less than 0.2 parts by weight, it is difficult to expect a heat buffering effect, and if it exceeds 0.2 parts by weight, the inside of the outer shell material (G3) difficult to be placed in.

The anionic polymer material (G7) is provided on either end (left end in Figure may further include. The anionic polymer material (G7) may be a mixture of p-styrenesulfonic acid and hydrogel pre-polymer (1:19 ratio) and UV cured.

It is preferable that 0.1 parts by weight of p-styrenesulfonic acid be included. However, if less than 0.1 parts by weight is used, the negative charge is not sufficient, and if it exceeds 0.1 parts by weight, the weight of the functional additive (G) is excessively increased and dispersibility is reduced. There is a problem.

The cationic material (G8) may be provided on the other end (right end in Figure x) of the two ends of the outer shell material (G3).

Polyethyleneimine, included in the cationic material (G8), is a polymer obtained by polymerizing ethyleneimine and is known to have the highest cation density among existing materials.

Illustratively, each of the above-mentioned cationic material (G8) and anionic polymer material (G7) is piled up on a polyethylene (PE) film or latex and heat-sealed to the above-mentioned outer covering material (G3) or attached by an adhesive or the like to the outer covering material. It may be provided outside (G3).

The posts G5 include 0.1 part by weight of aluminum and are provided on the outside of the outer cover material G3. The posts G5 may have a pillar shape and may be arranged in plural numbers at predetermined intervals on the outer surface of the outer cover material G3. Aluminum is used because it is a light metal. If it exceeds 0.1 part by weight, the functional additive (G) becomes too heavy and dispersibility is reduced, and if it is less than 0.1 part by weight, the length or width is excessively reduced, which reduces durability.

Exemplarily, the inner end of the post G5 may be attached to the outside of the outer covering material G3 using a known adhesive or the like. As another example, the outer covering material G3 may have a fitting groove recessed from the outer surface to the inside, and the inner end of the post G5 may be inserted into the fitting groove.

Each of the plurality of coupling members (G6) is provided on the outer side of each of the plurality of posts (G5), and the width may decrease toward the outer side.

Here, the inner side may refer to the center side of the functional additive (G), and the outer side may refer to the radial direction side from the center side.

The waterproofing material (GS) may contain a number of units (GU) of the functional additive (G), and the above-described units (GU) are separated from neighboring units (GU) by shear force when stirring in the waterproofing material (GS), causing the waterproofing material (GU) to be separated from the waterproofing material (GS). GS), functional additives (G), and other additives can be improved in agitation.

After mixing or in the process of applying the waterproofing material (GS) to the first slope 112 or after being applied to the first slope 112, the neighboring units (GU) are anionic polymer material (G7) and cationic material ( G8) become closer to each other due to electrostatic attraction between them, and the above-mentioned bonding member (G6) of one of the neighboring units (GU) (hereinafter referred to as the first unit) includes styrene butadiene rubber (SBR). As a result, it is elastically deformed (compressively deformed) and enters between a plurality of coupling members (G6) provided on the outside of another one of the neighboring units (GU) (hereinafter referred to as the second unit).

When the binding member (G6) of the first unit passes between the binding members (G6) of the second unit, the anionic polymer material (G7) of the first unit and the cationic material (G8) of the second unit are electrostatically charged. They can be attached to each other by attraction, and the coupling member (G6) of the first unit can be elastically restored and have its original shape with a width that decreases toward the outside.

At this time, the inner end of the above-mentioned first unit coupling member (G6) and the inner ends of the second unit coupling members (G6) are mutually supported and locked (locking coupling), thereby preventing the first and second units from being separated from each other. Thus, neighboring units (GU) are bonded to each other, and the electrostatic attraction of the neighboring units (GU) prevents the waterproofing material (GS) from expanding due to heat, and toughness can be added to the waterproofing material (GS).

The present invention described above with reference to the accompanying drawings can be modified and modified by those skilled in the art, and such modifications and changes should be construed as falling within the scope of the present invention.
