Summary of the Invention

Problems to be Solved by the Invention

[0006] In view of the above circumstances, the present invention aims to provide an economical temporary support column that simplifies the structure and can be easily and reliably erected and fixed in holes such as suspension holes in the covering plate. [Means for solving the problem]

[0007] The present invention, which solves the aforementioned problems, is characterized by comprising: a base plate disposed on the upper surface of a fixing member; a support column erected on the upper surface of the base plate; a hook provided on the lower surface of the base plate and penetrating and engaging with a through hole formed in the fixing member; a plurality of female screw holes formed in the base plate; and bolts that are screwed into each of the plurality of female screw holes from the upper part (Claim 1).

[0008] In the temporary support column of the present invention with the above configuration, first, a base plate is placed on the upper surface of a through hole formed in a fixing member, a hook provided on the lower surface of the base plate is passed through the through hole of the fixing member, and then the base plate is slid to lock the hook to the lower surface of the through hole of the fixing member.

[0009] Next, when the multiple bolts screwed into each of the female screw holes are tightened evenly, the lower ends of each bolt come into contact with and are pressed against the fixing member, causing the base plate to rise and creating a space between the fixing member and the base plate. At the same time, the bent portion of the hook is completely locked into the lower surface of the through hole in the fixing member.

[0010] Therefore, the bolts and hooks allow the support columns to be easily and securely erected and fixed to the upper surface of the covering plate, such as the suspension holes. Furthermore, the temporary support columns configured as described above can be removed from the fixing members by following the reverse procedure of the above steps.

[0011] The length of the bent portion at the lower end of the hook is determined by pre-measuring the inner diameter of the through-hole formed in the fixing member to be a length that allows for easy penetration and secure locking.

[0012] One embodiment of the present invention is characterized in that the female screw holes are formed at opposing positions on the base plate (Claim 2). According to this embodiment, the horizontal installation of the base plate and the vertical installation of the support column associated with the horizontal installation are facilitated by even tightening of the bolts screwed into the female screw holes. [Effects of the Invention]

[0013] According to the present invention, the structure can be simplified, and support columns can be easily and reliably erected and fixed into holes such as suspension holes in the covering plate. Furthermore, the cost can be reduced. [Brief explanation of the drawing]

[0014] [Figure 1] This is a perspective view showing the usage state of the temporary support column of the present invention. [Figure 2] This is a perspective view of the upright fixing section of the temporary support column. [Figure 3] This is a cross-sectional view of the upright fixing section of the temporary support column. [Modes for carrying out the invention]

[0015] An embodiment of the present invention will be described below with reference to the drawings. Figure 1 shows the temporary support column of the present invention in use.

[0016] As shown in Figure 1, the temporary support column P of the present invention is installed upright on the upper surface of a fixing member A, such as a covering plate. In the figure, 1 is a base plate, 2 is a support column installed upright on the upper surface of the base plate 1, 3 is a reinforcing member that holds the support column 2 upright on the base plate 1, and 4 is a holding part for, for example, a lifeline 5. Also, 6 is a through hole, such as a suspension hole, formed in the fixing member A. The shape of the base plate 1 is arbitrary according to the installation location. Furthermore, hollow material is used for the support column 2 to reduce weight.

[0017] In the present invention, as shown in FIGS. 2 and 3, a hook 7 that penetrates and is locked to a through-hole 6 formed in the fixing member A is formed on the lower surface of the base plate 1. The length of the bent portion at the lower end of the hook 7 is formed to be a length that can penetrate the through-hole 6 formed in the fixing member A and be locked to the lower surface of the through-hole. Further, the formation position of the hook 7 is preferably directly below the column 2.

[0018] Next, a plurality of female screw holes 8 are formed in the base plate 1. In the illustrated embodiment, considering the thickness, strength, etc. of the base plate 1, nuts 9 are separately fixed to the positions of the female screw holes 8 formed in the base plate 1 to constitute the female screw holes 8.

[0019] Furthermore, bolts 10 are screwed into the plurality of female screw holes 8 from the upper surface of the base plate 1, respectively.

[0020] The female screw holes 8 are preferably formed at opposite positions of the base plate 1. As a result, by evenly tightening the bolts 10 screwed into the female screw holes 8, the base plate 1 can be horizontally installed and the column 2 can be vertically installed along with the horizontal installation.

[0021] For the temporary support column S of the present invention having the above configuration, the base plate 1 is disposed on the upper surface of the through-hole 6 formed in the fixing member A, the hook 7 formed on the lower surface of the base plate 1 is penetrated into the through-hole 6 formed in the fixing member A, and then the base plate 1 is slid to lock the bent portion of the hook 7 to the lower surface of the through-hole 6 of the fixing member A.

[0022] Thereafter, when the bolts 10 screwed into the respective female screw holes 8 are evenly tightened by a jig, the lower ends of the respective bolts 10 come into contact with and press against the fixing member A, the base plate 1 is lifted, a space S is generated between the fixing member A and the base plate 1, and at the same time, the hook 7 is completely locked to the lower surface of the through-hole 6 of the fixing member A. Therefore, the column 2 can be easily and reliably erected and fixed on the upper surface such as the suspension hole of the covering board by the action of the respective bolts 10 and the hook 7.

Industrial Applicability

[0023] According to the present invention, a support column can be easily and surely erected and fixed on the upper surface of a fixing member, and the safety of a passageway at a construction site or the like can be ensured. Furthermore, cost reduction is achieved, and the industrial applicability is great.
