Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. It is not. Like numbers refer to like elements in the figures.

1 is a front view showing a temporary lifting device according to a preferred embodiment of the present invention.

Referring to Figure 1, the temporary lifting device according to a preferred embodiment of the present invention as a device for elevating the temporary platform 900 including a vertical beam 100 is installed on the outer wall of the structure, the outer wall (S) of the building structure and Elevator to step up and down the vertical beam 100 in a vertical direction by engaging with at least one of the plurality of locking projections 101 formed along the vertical direction at regular intervals to the vertical beam 100 installed on the opposite side. A plurality of ashes 300 and the outer wall S are installed along a portion where the vertical beams 100 are to be installed and are engaged with at least one of the locking protrusions 101 of the vertical beams 100. Guide guide shoe 200 for supporting the vertical beam (100).

The temporary bench 900 is installed on the side facing the structure outer wall (S) so that various operations can proceed to the building structure outer wall (S) to serve as a kind of scaffolding.

The hypothesis 900 is formed in a three-dimensional frame-shaped frame structure including at least one or more plates 901 that can be supported by a worker or a work article.

That is, the hypothesis 900 is orthogonal to the vertical beam 100 so that the vertical beam 100 is installed vertically on the side facing the structure outer wall (S), and the plate 901 can be installed horizontally. And a horizontal beam 902 connected in a direction, and an inclined beam 903 connected to the vertical beam 100 and the horizontal beam 902 to be inclined to reinforce the rigidity of the temporary table 900.

The vertical beam 100 may be installed in a two-row structure (not shown) on the side facing the structure outer wall (S), a plurality of obstacles at regular intervals along the vertical direction on the side facing the structure outer wall (S). The group 101 is projected.

As such, the hypothesis 900 may be elevated in the upward or downward direction by the lifting substrate 300 and the guide locking shoe 200 which are engaged with the locking projection 101 of the vertical beam 100 to drive up and down. .

2 is a perspective view showing a temporary lifting device according to a preferred embodiment of the present invention, Figure 3 is a state diagram showing the operating state of the temporary lifting device shown in FIG.

Referring to FIGS. 2 and 3, the lifting base 300 is a component installed on the guide locking shoe 200 to elevate and move the temporary table 900 including the vertical beam 100 in an upward or downward direction. .

The lifting base 300 is a hydraulic cylinder 310 having a piston rod 320 to move forward or backward along the lifting direction of the temporary (900) and the rotation pin is installed on the upper end of the piston rod 320 It is coupled to the 331 is rotated along the lifting direction of the hypothesis 900, while the up-entrance to the locking projection 101 of the vertical beam 100 is engaged with each other and the hook is rotated upward when entering the locking projection 101 ( 330).

As such, the lifting base 300 is required to elevate the temporary weight 900 of the relatively heavy weight, it is preferable that an advantageous hydraulic method is applied to obtain a large force.

For example, the hydraulic cylinder 310 receives the hydraulic pressure generated by the hydraulic source (not shown), the hydraulic pump (not shown), the directional valve (not shown), etc. through the hydraulic hoses (301, 302) piston rod ( Reciprocate 320).

The hook 330 is preferably formed in a shape that is interlocked with the engaging projection 101 of the vertical beam 100, rotates along the lifting direction of the temporary table 900, but when the piston rod 320 is driven up In order to maintain the horizontal state to be engaged with the engaging projection 101 of the vertical beam 100, the downward rotation is limited by the bracket 332 coupled to the upper end of the piston rod (320).

In addition, the lifting substrate 300 must be retreated after driving the piston rod 320 within the maximum stroke length of the hydraulic cylinder 310 to raise the vertical beam 100. In this case, since the hook 330 enters and interferes with the locking projection 101 of the vertical beam 100, the hook 330 should be configured to avoid such interference phenomenon.

Therefore, the hook 330 interferes with the locking projection 101 of the vertical beam 100 when the piston rod 320 is retracted. However, the hook 330 is coupled with the pivot pin 331 so that the hook 330 rotates upward as shown in FIG. 3. Avoid.

As such, the hook 300 may be configured to be restored to a horizontal state by its own weight after the upward rotation for avoiding the interference phenomenon with the locking protrusion 101, and to always receive an elastic force in a downward direction by a torsion spring (not shown). It may be configured to automatically return after the configuration and upward rotation.

On the other hand, the lifting base 300 is installed in the form that one side is coupled to the hydraulic cylinder 310 and the other side closely wraps the wing piece 102 of the vertical beam 100 to guide the correct position of the hydraulic cylinder (310) It may further comprise a first guide means (311).

That is, since the first guide means 311 partially enters and surrounds both sides of the wing piece 102 of the vertical beam 100, as shown in FIG. 2, an upper portion of the hydraulic cylinder 310 surrounding the piston rod 320 is provided. There is an advantage that the hydraulic cylinder 310 can be stably positioned by offsetting the rotation moment that may occur.

In addition, the elevating substrate 300 is the one side is coupled to the piston rod 320 and the other side is installed in a form that wraps close to the wing piece 102 of the vertical beam 100 to guide the correct position of the hook 330 It may further comprise a two guide means (321).

That is, the piston rod 320 of the elevating substrate 300 may be rotated in the circumferential direction because it is a free end that is linearly moved in the vertical direction by the hydraulic cylinder 310 but is not coupled to any other fixture. Thus, when the hook 330 is rotated together by the rotation of the piston rod 320 may be a phenomenon that can not be normally engaged with the locking projection 101 when entering the locking projection 101 of the vertical beam 100. .

Therefore, the piston rod 320 of the elevating base material 300 can maintain the correct position of the hook 330 by the second guide means 321 to prevent its rotation.

The lifting base 300 is installed detachably on the guide locking shoe 200, the lower end of which is fixed to the outer wall (S) of the structure.

Specifically, the hydraulic cylinder 310 is a through hole 303 formed in the lower end portion of the through hole 303 in a state that is matched with the through hole 201 formed in both wing plates (200a) of the guide locking shoe 200 , 201) is coupled to the guide engaging shoe 200 by a coupling pin 240 penetrating.

Figure 4 is a perspective view showing a separate guide locking shoe of the temporary lifting device shown in FIG.

Referring to FIG. 4, the guide locking shoe 200 is engaged with the locking projection 101 of the vertical beam 100 to support the vertical beam 100, but the vertical beam 100 is provided on the lifting substrate 300. As a result, the supporting state is released during the elevating driving, and then the vertical beam 100 is a component that supports the vertical beam 100 again when the elevating driving is performed upward or downward to the target height.

The guide locking shoe 200 is preferably detachably coupled to the fixing base 210 is fixed to the structure outer wall (S).

Specifically, the fixing base 210 is fixed to the outer wall (S) of the structure by the conventional anchor bolt (B1), the guide locking shoe 200 is mutually by the fixing base 210 and the fastening pin 250 Combined.

More specifically, the guide engaging shoe 200 and the fixing base 210 are formed through holes 202 and 211 which are matched with each other, so that the fastening pins 250 are inserted through the through holes 202 and 211, respectively. It is a structure that is mutually coupled.

Since the guide jam shoe 200 can be separated from each other in the fixing substrate 210, the guide jam shoe 200 is released from the support state of the vertical beam 100 is dismantled in the fixing substrate 210 of the structure The advantage is that it can be reinstalled on another floor.

In addition, the guide locking shoe 200 is engaged with the locking projection 101 when the vertical beam 100 enters downward, and the latch bar that is vertically rotated by contacting the locking projection 101 when the vertical beam 100 enters upward. 220).

The latch bar 220 is preferably formed in a shape that is interlocked with the engaging projection 101 of the vertical beam 100, and inserted through the two wing plates (200a) of the guide locking shoe (200). It is coupled to the rotating pin 230 is installed so as to be able to rotate up and down along the lifting driving direction of the vertical beam (100) (see Fig. 5).

In addition, the guide locking shoe 200 has a guide channel 204 formed between the two wing plates (200a) is inserted into the vertical beam 100 is guided.

The guide channel 204 is formed in a structure in which the upper and lower ends have a larger width and narrower toward the middle so as to guide the vertical movement of the vertical beam 100.

In the above configuration, through holes 103 and 20 are formed in the overlapping portions of the vertical beam 100 and the guide locking shoe 200, respectively, and the safety coupling pins 270 inserted into the through holes 103 and 203 respectively. More).

Therefore, the vertical beam 100 and the guide locking shoe 200 are more firmly held in a fixed state by the safety coupling pin 270.

FIG. 5 is a cross-sectional state view showing a guide locking shoe operating state of the temporary lifting device shown in FIG. 2. 5 (a) is a state diagram in which the latching bar 220 of the guide locking shoe 200 and the locking protrusion 101 of the vertical beam 100 are engaged, and FIG. 5 (b) shows the guide locking. 5 is a state diagram in which the latching protrusions 220 enter the shoe 200 upward and the latch bar 220 is upwardly rotated, and FIG. 5C shows that the locking pins 260 are separated from the guide locking shoe 200. State diagram of the state.

The latch bar 220 is restricted or released downward rotation by the locking pin 260 is inserted between the wing plate 200a of the guide locking shoe 200.

That is, the latch bar 220 interferes with the locking projection 101 of the vertical beam 100 when the vertical beam 100 is driving down, so that the interference pin is avoided by separating the locking pin 260. It is configured to be.

Accordingly, the latch bar 220 may interfere with the locking projection 101 of the vertical beam 100 when the vertical beam 100 is driven down, but as shown in FIG. Interference is avoided by pivoting downward by separating from the guide jam shoe 220.

For example, the latch bar 220 is configured to always receive an elastic force in the downward direction by the torsion spring (not shown), so that the vertical beam 100 when the vertical beam 100 is lifted upward by the lifting substrate 300 When the locking projection 101 of the torsion spring is pushed upwards to overcome the elastic restoring force of the torsion spring and upwardly rotated, and the locking protrusion 101 passes through the latch bar 220, the elastic restoring force of the torsion spring is applied. It is returned by the retaining pin 260 and is provided to maintain the contact state. In addition, the latch bar 220 is no longer rotated downward because the lower side is supported by the locking pin 260.

Hereinafter, a method of elevating the temporary platform using the temporary lifting device according to an embodiment of the present invention.

6a to 6d is an operating state diagram for explaining a method of lifting the temporary platform using the temporary lifting device according to an embodiment of the present invention. Also, for convenience of explanation, the hypothesis 900 shows only the vertical beam 100.

Referring to FIG. 6A, the vertical beam 100 for manufacturing the temporary table 900 is lifted by a large crane (not shown) and guided downward into the channel 204 of the guide guide shoe 200 installed therein. .

While the vertical beam 100 is lowered, the guide locking shoe 200 releases the locking pins 260 until the vertical beam 100 is induced to descend to a predetermined position by the large crane, so that the vertical beam 100 It is preferable that the locking protrusion 101 and the latch bar 220 do not interfere with each other, and the hook 330 of the elevating substrate 300 also rotates upward so as not to interfere with the locking protrusion 101 of the vertical beam 100. Do.

On the other hand, when lowering the vertical beam 100 to the large crane, because the locking projection 101 is interfered with the hook 330 of the lifting material 300 may lower the lowering work, the lifting material 300 after the lowering work is completed ) May be mounted on the guide jam shoe (200).

When the vertical beam 100 is positioned at a desired position, for example, when the vertical beam 100 is positioned at the bottom surface, the locking pin 260 is inserted to support the latch bar 220, and the locking protrusion 101 is provided with the level of the guide locking shoe 200. It is loaded into the guide locking shoe 200 so as to enter the Chiba 220 downwardly engaging each other. Thus, the latch bar 220 is engaged with the engaging protrusion 101 to support the vertical beam 100, so that the vertical beam 100 does not go down anymore.

As such, the vertical beam 100 can be completed by assembling the hypothesis 900 in a state loaded on the guide locking shoe 200, and when the hypothesis 900 is completed, work can be performed between the corresponding layers of the structure. have.

Referring to FIG. 6B, when the vertical beam 100 is to be driven upward in the state in which the vertical beam 100 is loaded on the guide locking shoe 200, first, the lifting substrate 300 installed on the guide locking shoe 200 is provided. Drive up) to engage with the vertical beam (100).

In detail, when the hydraulic cylinder 310 of the lifting base 300 drives the piston rod 320 upwardly, the hooks 330 are stiffly coupled to the corresponding protrusion 101 of the vertical beam 100 and then vertically. The beam 100 is driven up by the hydraulic force of the hydraulic cylinder 310.

At this time, the vertical beam 100 is unloaded from the guide locking shoe 200 while being loaded on the lifting substrate 300.

Referring to FIG. 6C, the hydraulic cylinder 310 is continuously driven up while the vertical beam 100 is loaded on the lifting substrate 300 to raise the vertical beam 100 within its maximum stroke length.

Specifically, the vertical beam 100 is a state in which the engaging projection 101 is engaged with the hook 330 of the elevating substrate 300, so that the maximum stroke length when the hydraulic cylinder 310 of the elevating substrate 300 is driven up Is raised within.

While the vertical beam 100 is raised, the locking projection 101 of the vertical beam 100 pushes up the latch bar 220 of the guide locking shoe 200 upward, but the latch bar 220 pivots upward. As a result, interference is prevented.

Referring to FIG. 6D, when the vertical beam 100 rises by a desired height by the driving of the elevating material 300, for example, the distance between the locking protrusions 101, the locking protrusion 101 of the vertical beam 100 is guided. It is loaded by engaging with the latch bar 220 of the locking shoe 200.

When the lifting base member 300 drives the hydraulic cylinder 310 down and retracts the piston rod 320, the hook 330 of the piston rod 320 is in contact with the locking protrusion 101 of the vertical beam 100. Since the hook 330 is pivoted upward, interference is prevented.

On the other hand, the lifting substrate 300 repeats the vertical beam 100 step by step within the maximum stroke length of the lifting substrate 300, even if its maximum stroke length is smaller than the target height to raise the vertical beam 100. It is possible to raise to the target height.

For example, in a state as shown in FIG. 6D, the piston rod 320 of the elevating substrate 300 is retreated back, and a series of processes of raising the vertical beam 100 as described in FIGS. 6A to 6C are repeated vertically. It is possible to raise the beam 100 stepwise to the target height.

7A to 7D are operation state diagrams for explaining a method for lifting a temporary platform using a temporary lifting device according to an embodiment of the present invention. Also, for convenience of explanation, the hypothesis 900 shows only the vertical beam 100.

Referring to FIG. 7A, the vertical beam 100 is coupled to the latch bar 220 of the guide locking shoe 200, and the locking protrusion 101 is loaded on the guide locking shoe 200. In this state, the hydraulic cylinder 310 drives the piston rod 320 upwardly to engage the hook 330 and the locking protrusion 101 with each other.

Referring to FIG. 7B, when the vertical beam 100 is to be driven downward, first, the latch bar 220 of the guide locking shoe 200 engaged with the locking protrusion 101 should be rotated downward, and thus perpendicular to the vertical beam 100. The latching protrusion 101 of the beam 100 rotates downwardly by the latch bar 220 by releasing the locking pin 260 while being engaged with and supported by the hook 330.

Referring to FIG. 7C, the hydraulic cylinder 310 is driven downward in a state in which the latch bar 220 is rotated downward to descend within the maximum stroke length.

Specifically, the vertical beam 100 is lowered by the desired length within the maximum stroke length, for example, by the distance between the locking projections 101 by the lowering driving of the lifting substrate 300.

Referring to FIG. 7D, in the state where the vertical beam 100 is lowered by a desired length, for example, the distance between the locking protrusions 101, the latch bar 220 is supported so that the latch bar 220 is supported by the locking pin 260. Restore and install the locking pin 260.

Therefore, the vertical beam 100 is supported by the engaging projection 101 is engaged by engaging downwardly into the latch bar 220 of the guide locking shoe 200, the vertical beam 100 is guide locking shoe 200 Since it is supported by the vertical beam 100 can be unloaded in the lifting substrate 300

On the other hand, the lifting substrate 300 repeats the vertical beam 100 step by step within the maximum stroke length of the lifting substrate 300 even when its maximum stroke length is smaller than the target height to be lowered of the vertical beam 100. It is possible to lower to the target height.

For example, in the state as shown in Figure 7d by rotating the hook 330 of the lifting substrate 300 in the state to avoid the interference with the locking projection 101 of the vertical beam 100, the maximum stroke length Ascending forward within, restoring the hook 330 is engaged to the corresponding engaging projection 101 of the vertical beam (100). As described with reference to FIGS. 7A to 7C, it is possible to repeatedly lower the vertical beam 100 to the target height by repeating a series of processes of lowering the vertical beam 100.

The present invention has been illustrated and described with reference to certain preferred embodiments, but the present invention is not limited to the above-described embodiments and has ordinary skill in the art to which the present invention pertains without departing from the concept of the present invention. Various changes and modifications are possible by the user.

As described above, the present invention, except that the large crane is used once during the initial loading of the vertical beam, since the construction work can be performed without the use of large cranes during the construction of the construction, the time required for lifting the temporary construction And it is possible to reduce the cost and significantly reduce the air and expenses required for the entire public row.

In addition, the present invention, it is possible to use a small capacity lifting substrate having a maximum stroke length is smaller than the height of the floor between the structures, there is an effect that it is possible to safely and easily step up the temporary construction step to the target height.

In addition, the present invention, because the guide locking shoe can be separated from the outer wall of the structure can be dismantled and used continuously without having to be installed for each floor of the structure, there is an economical effect.
