Summary of the Invention

Problems to be Solved by the Invention

[0006] In view of the above circumstances, the present invention aims to provide a temporary support column that ensures the safety of a passageway by fitting it into the mounting hole of the fixing member and firmly fixing the temporary support column upright, thereby preventing shifting or rattling in the upright portion of the support column and providing durability. [Means for solving the problem]

[0007] The present invention, which solves the above problems, is a temporary support column comprising: a base plate disposed on the upper surface of a fixing member; a support pipe provided on the base plate; a fastening rod having a hook at its lower end that engages with a through hole in the fixing member, and which is incorporated so as to be movable in the axial direction within the support pipe, passing through the base plate; a nut that is screwed onto a male threaded portion formed on the upper end of the fastening rod; and a handle for engaging the hook with the fixing member,

[0008] The invention is characterized by comprising: a hook formed to a length such that the bent portion can pass through the through-hole and can be locked into the through-hole; and a base plate having a slip-preventing member provided on its lower surface that fits into the space created between the vertical portion of the hook and the through-hole when the bent portion of the hook is locked into the through-hole (Claim 1).

[0009] In the present invention, the inner diameter of the through-hole provided in the fixing member, for example, a suspension hole formed in the covering plate, is measured in advance, and the length of the bent portion at the lower end of the hook is formed to pass through the through-hole and to be able to lock into the through-hole.

[0010] Furthermore, the thickness of the anti-slip member provided on the lower surface of the base plate is formed to a thickness that fits the space created between the vertical portion of the hook and the through-hole when the bent portion of the hook is engaged with the through-hole.

[0011] Therefore, according to the present invention, the through-hole provided in the fixing member is completely sealed by the vertical portion of the hook and the anti-slip member, the entire support column is firmly fixed upright on the fixing member, and durability is further improved.

[0012] One embodiment of the present invention is characterized in that a recess is formed in the base plate at an opposing position to which the support pipe fits (Claim 2).

[0013] According to this implementation method, temporary support columns can be stacked, and handling such as transporting the temporary support columns and organizing and tidying them up after work is completed is easy.

[0014] In other words, by placing a second temporary support column in the opposite direction on top of a first temporary support column placed horizontally, and fitting the support pipe portion of the second temporary support column into a recess formed in the base plate of the first temporary support column, it is possible to stack two layers while maintaining stability. Similarly, it is possible to stack multiple layers sequentially. [Effects of the Invention]

[0015] According to the present invention, the through-holes provided in the fixing member are completely sealed by the vertical portion of the hook and the anti-slip member, so that the entire temporary support column is firmly fixed upright on the fixing member, and furthermore, durability is obtained and the effect of ensuring the safety of the passageway is obtained.

[0016] Furthermore, according to one embodiment of the present invention, since the temporary support columns can be stacked, the effect of facilitating the transportation of the temporary support columns and handling such as organizing and tidying up after the completion of work can be obtained. [Brief explanation of the drawing]

[0017] [Figure 1] This is a perspective view of the temporary support column of the present invention. [Figure 2] This is a partial cross-sectional diagram illustrating the upright installation of the temporary support column of the present invention. [Figure 3] This is a perspective view showing the stacked configuration of the temporary support columns of the present invention with the handles omitted. [Figure 4] This is a perspective view showing the usage state of the temporary support column of the present invention. [Figure 5] Another embodiment of the top of the temporary support column is shown in a front view (a) and a left side view (b). [Modes for carrying out the invention]

[0018] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0019] Fig. 1 shows the temporary support column of the present invention, and Fig. 4 shows its usage state.

[0020] As shown in Figs. 4 and 1, the temporary support column S of the present invention includes a base plate 1 disposed on the upper surface of a fixing member A such as a lining plate, a support column pipe 4 provided with a support portion 3 of a main rope 2 and the like and provided on the base plate 1, a fastening rod 7 provided with a hook 6 locked to a through hole 5 as a hanging hole provided in the fixing member A at its lower end and movably incorporated in the axial direction in the support column pipe 4 through the base plate 1, a nut 9 screwed to a male screw portion 8 formed at the upper end of the fastening rod 7, and a handle 10 for rotating the nut 9 to lock the hook 6 to the through hole 5 of the fixing member A.

[0021] The hook 6 provided at the lower end of the fastening rod 7 is formed in an L shape and has a bent portion 6a in the horizontal direction and a vertical portion 6b in the vertical direction.

[0022] In the present invention, the bent portion 6a of the hook 6 is formed to have a length that can pass through the through hole 5 and can be locked to the through hole 5. Further, in the present invention, when the bent portion 6a of the hook 6 is locked to the through hole 5, a displacement preventing member 11 is provided at a position that fits into the space generated between the vertical portion 6b of the hook 6 and the through hole 5. Specifically, the displacement preventing member 11 is provided on the lower surface of the base plate 1 at a position adjacent to the vertical portion 6b of the hook 6. In the drawing embodiment, an angle member is used as the displacement preventing member 11, but other shapes may also be used.

[0023] Also, the length of the bent portion 6a of the hook 6 and the thickness of the displacement preventing member 11 are designed to fit the through hole 5 by measuring the inner diameter of the through hole 5 in advance.

[0024] In the diagram, 12 is a recess in the base plate 1 where the support pipe 4 fits, 13 is a mark indicating the direction of the bent portion 6a of the hook 6, and 14 is a mounting portion for safety features such as a baseboard.

[0025] Next, the process of erecting and installing the temporary support column S of the present invention relative to the fixing member A will be explained. Figure 2(a) shows the state at the start of erecting and installing the temporary support column S, and Figure 2(b) shows the state after the erection and installation of the temporary support column is completed.

[0026] First, as shown in Figure 2(a), with the temporary support column S suspended, the handle 10 is operated to make the hook 6 protrude downward. Next, the bent portion 6a of the hook 6 is lowered and passed through the through hole 5.

[0027] Next, in Figure 2(b), the temporary support column S is slid to the right so that the bent portion 6a of the hook 6 is engaged with the through-hole 5, and the base plate 1 is placed on the upper surface of the fixing member A. In this state, the vertical portion 6b of the hook 6 and the anti-slip member 11 completely block the through-hole 5.

[0028] Subsequently, by operating the handle 10 to raise the hook 6 and completely locking the bent portion 6a of the hook 6 into the opening of the through hole 5, the temporary support column S is firmly erected in the state shown in Figure (b).

[0029] As described above, according to the present invention, the through-hole 5 provided in the fixing member A is completely closed by the vertical portion 6b of the hook 6 and the anti-slip member 11, so that the entire temporary support column S is firmly fixed upright on the fixing member A, has durability and ensures the safety of the passageway.

[0030] Figure 3 is a perspective view showing the stacked state of the temporary support posts S of the present invention. Note that the male screw portion 8, nut 9, and handle 10 of each temporary support post S are omitted in this figure.

[0031] First, a second temporary support column S2 is placed on top of the first temporary support column S1, which is placed horizontally, in the opposite direction. By fitting the support pipe 4 of the second temporary support column S2 into the recess 12 formed in the base plate 1 of the first temporary support column S1, a stable two-tiered stacking is possible. In the same manner, multiple tiers can be stacked sequentially. This stacking structure makes it easy to transport a large number of temporary support columns S and to handle them, such as organizing and tidying them up after work is completed.

[0032] Figure 5 shows another embodiment of the head of the temporary support column S, where Figure (a) is a front view and Figure (b) is a left side view.

[0033] This embodiment is identical to the previous embodiment in terms of the support pipe 4, fastening rod 7, male screw portion 8, nut 9, and handle 10. However, an arm 16 is newly rotatably attached to the upper end of the support pipe 4 by a pin 15. The arm 16 has two arm pieces 16a and a receiving member 17 provided at the upper end of the arm pieces 16b, which are each attached to the support pipe 4 by the pin 15. As shown in Figure 5, the arm 16 rotates between a position where the receiving member 17 abuts against the nut 9 and a position where the receiving member 17 moves away from the nut 9, as shown by the dashed line in Figure 5(b).

[0034] When the receiving member 17 is in contact with the nut 9, the handle 10 can be rotated to engage the hook 6 (not shown) with the through hole 5 and lock it in place. In other words, when the receiving member 17 is in contact with the nut 9, it constitutes the contact portion of the support pipe 4 that the nut 9 contacts.

[0035] On the other hand, as shown by the dashed line in Figure 5(b), when the arm 16 is rotated so that the receiving member 17 is away from the nut 9, the fastening rod 7 can be moved vertically to a position where the nut 9 contacts the upper end of the support pipe 4 without rotating the handle 10. When the fastening rod 7 is moved in this way, the hook 6 protrudes significantly below the base plate 1, and the engagement between the hook 6 and the through hole 5 can be released. Furthermore, when the temporary support S is placed on the fixing member A and attached to the fixing member A, the lower end of the fastening rod 7 protrudes significantly below the base plate 1, making the attachment work easier. [Industrial applicability]

[0036] According to the present invention, temporary support columns can be firmly erected and fixed on a fixing member, providing durability and ensuring the safety of passageways at construction sites and other locations. Furthermore, they are easy to handle due to their stackable design, and have great industrial applicability. [Explanation of Symbols]
