DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

FIGS. 1 to 7 illustrate a safety recovery support fixture according to the present invention that is fixed to a typical ground surface 1.

According to FIGS. 1 to 7, the safety recovery support fixture according to the present invention includes a support bar 10 extending in an up-down direction and having screw threads 11 formed on a circumferential surface of a lower end, a fixer 20 disposed at the lower end of the support bar 10, a connector 30 coupled to an upper end of the support bar 10, and a support fixture 40 coupled to the connector 30 and supporting a structure.

The support bar 10 is configured in the form of a round bar that extends in the up-down direction and has the screw threads 11 formed on the lower end.

The fixer 20 includes a lifting/lowering block 21 extending in a lateral direction and having a coupling hole 21a, which is screw-coupled to the screw threads 11 of the support bar 10, formed at a central portion to pass through upper and lower surfaces, a pair of anchor blades 22 coupled to both ends of the lifting/lowering block 21 to be pivotable in the up-down direction, a support block 23 extending in the lateral direction and having a through-hole 23a, to which the support bar 10 is rotatably coupled, formed at a central portion, and a pair of connecting rods 24 coupled to both ends of the support block 23 to be pivotable in the up-down direction and having distal end portions hinge-coupled to the anchor blades 22.

The lifting/lowering block 21 includes a tubular member 21b extending in the up-down direction and having the coupling hole 21a formed therein and a pair of brackets 21c disposed at both sides of the tubular member 21b.

In addition, a catching step 21d having an upper surface on which the anchor blade 22 is seated is formed at each of opposite ends of the lifting/lowering block 21, that is, at outer ends of the brackets 21c.

The anchor blade 22 includes an anchor plate 22a extending in the up-down direction and a blade main body 22b disposed at an outer side surface of the anchor plate 22a and having a lower end pivotably coupled to the lifting/lowering block 21.

At this time, a width of the anchor plate 22a in a front-rear direction is formed to be thicker than a width of the blade main body 22b so that front and rear side surfaces of the anchor plate 22a protrude in a front-rear direction of the blade main body 22b.

In addition, an upper end of the anchor plate 22a is bent in a direction adjacent thereto.

Accordingly, as illustrated in FIG. 3, when the anchor blade 22 is pivoted downward, a lower end of the anchor plate 22a is seated on the upper surface of the catching step 21d and fixed so as not to be pivoted downward.

The support block 23 is coupled to the support bar 10 to be rotatable but not be able to move upward or downward so that the support block 23 is located above the screw threads 11.

To this end, a protruding step 12 supporting the upper and lower surfaces of the lifting/lowering block 21 is formed on the support bar 10.

In addition, brackets 23b to which upper ends of the connecting rods 24 are hinge-coupled are disposed at both sides of the support block 23.

The connector 30 is configured in a disc shape, a lower coupling tube 31 screw-coupled to the upper end of the support bar 10 is disposed at a lower side of the connector 30, and an upper coupling tube 32 to which the support fixture 40 is screw-coupled is disposed at an upper side of the connector 30.

A method of installing the safety recovery support fixture configured as above in the ground surface 1 will be described below.

First, as illustrated in FIG. 4, an appropriate excavation hole 2 is formed in the ground surface 1, and the fixer 20 is inserted into the excavation hole 2. In this state, when the support bar 10 is rotated, as illustrated in FIG. 5, the lifting/lowering block 21 moves upward due to a screw action of the screw threads 11, and accordingly, the connecting rods 24 are pivoted upward, and the anchor blades 22 are pivoted outward.

As a result, upper ends of the anchor blades 22 are fixed after digging into a circumferential portion of the excavation hole 2.

At this time, the lower end of the anchor plate 22a of each anchor blade 22 is seated on the upper surface of the catching step 21d, and each anchor blade 22 is fixed so as not to be pivoted further.

In addition, construction of a structure may be completed after filling the excavation hole 2 with soil to close the excavation hole 2 as illustrated in FIG. 6, and then coupling the connector 30 and the support fixture 40 to the upper end of the support bar 10 and fixing the structure to the support fixture 40 as illustrated in FIG. 7.

In addition, in a case in which the structure is demolished, when the support bar 10 is rotated in the opposite direction, the lifting/lowering block 21 moves downward, and the anchor blades 22 are pivoted upward.

As a result, areas of the anchor blades 22 decrease, and workers are able to pull the support bar 10 upward and pull out and remove the safety recovery support fixture upward from the ground surface 1.

The safety recovery support fixture configured as above includes the support bar 10 extending in the up-down direction and having the screw threads 11 formed on the circumferential surface of the lower end, and the fixer 20 disposed at the lower end of the support bar 10, the fixer 20 includes the lifting/lowering block 21 extending in the lateral direction and having the coupling hole 21a, which is screw-coupled to the screw threads 11 of the support bar 10, formed at the central portion to pass through the upper and lower surfaces, the pair of anchor blades 22 coupled to both ends of the lifting/lowering block 21 to be pivotable in the up-down direction, the support block 23 extending in the lateral direction and having the through-hole 23a, to which the support bar 10 is rotatably coupled, formed at the central portion, and the pair of connecting rods 24 coupled to both ends of the support block 23 to be pivotable in the up-down direction and having the distal end portions hinge-coupled to the anchor blades 22, and in this way, the safety recovery support fixture can be fixed to the ground surface 1 by spreading the anchor blades 22 in the state in which the fixer 20 is inserted into the ground surface 1 and can be removed by being pulled upward in the state in which the anchor blades 22 are narrowed.

Accordingly, the safety recovery support fixture can be firmly fixed to the ground surface 1 to support a structure and can be easily recovered after the structure is demolished, and there is an advantage that environmental destruction can be prevented.

In addition, the catching step 21d having the upper surface on which the anchor blade 22 is seated is formed at each of opposite ends of the lifting/lowering block 21, the anchor blade 22 includes the anchor plate 22a extending in the up-down direction and the blade main body 22b disposed at the outer side surface of the anchor plate 22a and having the lower end pivotably coupled to the lifting/lowering block 21, and when the anchor blade 22 is pivoted downward, the lower end of the anchor plate 22a is seated on the upper surface of the catching step 21d and fixed.

Accordingly, there is an advantage that it is possible to effectively prevent the anchor blades 22 from moving in the up-down direction in a state in which the anchor blades 22 are spread outward and fixed to the ground surface 1.

In the case of the present embodiment, the safety recovery support fixture has been described as being installed on the ground surface 1, but the safety recovery support fixture may be installed on the bottom of a tidal flat or the ocean.

FIG. 8 illustrates another embodiment according to the present invention in which a support plate 50 supporting a lower side surface of the connector 30 is disposed on the upper end of the support bar 10.

The support plate 50 has a through-hole 51, through which the support bar 10 passes, formed therein and is coupled to the upper end of the support bar 10 to come in close contact with the ground surface 1. The support plate 50 is configured in the form of a disk spring of which a central portion protrudes upward.

In the safety recovery support fixture configured as above, since the support plate 50 is disposed on the upper end of the support bar 10 and comes in close contact with a wide area of the ground surface 1, a load applied to the safety recovery support fixture is transferred to be widely distributed to the ground surface 1 through the support plate 50, and there is an advantage that it is possible to more effectively prevent the safety recovery support fixture from subsiding due to a load of the structure.

In particular, since the support plate 50 is configured in the form of a disk spring of which the central portion protrudes upward, there is an advantage that the support plate 50 can be elastically deformed and absorb impact when strong impact is applied due to an earthquake, etc.

FIGS. 9 to 11 illustrate a third embodiment according to the present invention in which the safety recovery support fixture further includes a close contact detector 61 disposed at the catching step 21d to detect close contact between the anchor plate 22a of the anchor blade 22 and the catching step 21d, a rotation detector 62 disposed at the support block 23 to detect rotation of the support bar 10, a controller 63 receiving signals from the close contact detector 61 and the rotation detector 62, and an alarm device 64 connected to the controller 63.

The close contact detector 61 is disposed to be buried in the catching step 21d and uses a limit switch having a push button 61a protruding upward from an upper surface thereof. As illustrated in FIG. 11, when the lower end of the anchor plate 22a comes in close contact with the catching step 21d, the push button 61a is pressed downward, and the close contact is detected.

The rotation detector 62 is disposed in the through-hole 23a of the support block 23 and uses a rotation sensor that detects rotation of the support bar 10 coupled to the through-hole 23a.

Since various types of rotation sensors have been developed and used for various purposes, detailed description of the rotation sensor will be omitted.

The alarm device 64 is configured to output an alarm sound when operated.

In the safety recovery support fixture configured as above, the controller 63 monitors signals from the close contact detector 61 and the rotation detector 62 that indicate whether the anchor blades 22 are pivoted outward and the lower ends of the anchor plates 22a are in close contact with the catching steps 21d.

In addition, when the rotation detector 62 detects that the anchor plates 22a of the anchor blades 22 are spaced apart from the catching steps 21d in a state in which the support bar 10 is not rotated, the controller 63 determines that an abnormality has occurred in the fixer 20 and operates the alarm device 64 to inform of the abnormality.

That is, in a normal state of the fixer 20, the anchor blades 22 should not be pivoted upward unless the support bar 10 is rotated.

However, the anchor plates 22a of the anchor blades 22 being spaced apart from the catching steps 21d even when rotation of the support bar 10 is not detected by the rotation detector 62 indicates that an abnormality has occurred in the fixer 20.

Accordingly, there is an advantage in that, when an abnormality that cannot be found visually occurs in the fixer 20, the alarm device 64 is operated to inform workers of the abnormality so that the workers can promptly maintain and repair the safety recovery support fixture.

A safety recovery support fixture according to the present invention includes a support bar 10 extending in an up-down direction and having screw threads 11 formed on a circumferential surface of a lower end, and a fixer 20 disposed at the lower end of the support bar 10, the fixer 20 includes a lifting/lowering block 21 extending in a lateral direction and having a coupling hole 21a, which is screw-coupled to the screw threads 11 of the support bar 10, formed at a central portion to pass through upper and lower surfaces, a pair of anchor blades 22 coupled to both ends of the lifting/lowering block 21 to be pivotable in the up-down direction, a support block 23 extending in the lateral direction and having a through-hole 23a, to which the support bar 10 is rotatably coupled, formed at a central portion, and a pair of connecting rods 24 coupled to both ends of the support block 23 to be pivotable in the up-down direction and having distal end portions hinge-coupled to the anchor blades 22, and in this way, the safety recovery support fixture can be fixed to a ground surface 1 by spreading the anchor blades 22 in a state in which the fixer 20 is inserted into the ground surface 1 and can be removed by being pulled upward in a state in which the anchor blades 22 are narrowed.

Accordingly, the safety recovery support fixture can be firmly fixed to the ground surface 1 to support a structure and can be easily recovered after the structure is demolished, and there is an advantage that environmental destruction can be prevented.
