Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a handrail pillar for a lining plate used for installing a handrail on a lining plate used for various road surface constructions, floor plates for temporary piers, etc. With respect to the above, it is characterized in that it can be installed only by using the through holes provided on the upper surface of the lining plate, and that it is safe and easy to handle such as transportation and storage.

[Prior Art] Conventionally, in various road surface constructions using a lining board and constructions such as floor boards for temporary piers, it is mandatory to equip the lining board with handrails in order to maintain safety. Is
The lining plate was constructed by welding an angle member for mounting the handrail pillar, or by directly welding the handrail pillar side.

In addition, detachable handrail posts that do not require welding have recently been proposed (Japanese Utility Model Publication No. 61-102606 and Japanese Utility Model Publication No. 62-69542).
No.

[Problems to be Solved by the Invention] In the above-mentioned conventional welding method, the welded portion cannot be completely removed after use, and the outer appearance of the lining plate and the handrail column is likely to be deformed. In this case, it was uneconomical because it was disposed of only once.

Also, the recently proposed detachable handrail post without welding will eliminate the above-mentioned uneconomical, but it is inconvenient in that it cannot be used unless the periphery of the lining plate is open. Remains, and the supporting plate and the supporting plate are projected to the walking surface from the peripheral edge of the lining plate to the through hole provided on the upper surface, and further the supporting bolts are exposed, which disturbs walking or trips. There were cases.

The present invention has been made in view of the above circumstances, is economical because it can be used repeatedly as many times as possible without deforming the appearance, and uses only the through holes provided on the upper surface of the lining plate. It is an object of the present invention to provide a handrail post for a lining plate that can be installed in a simple manner and is safe and easy to handle such as transportation and storage.

[Means for Solving the Problems] In order to solve the above problems, according to the present invention, a base plate having a through hole at the position of the cutout is fixed to the lower end of a column with one side of the lower part cut out, A fixing bolt is inserted through the through hole, and below the base plate, a fixing plate is provided which can be inserted into the through hole provided on the upper surface of the lining plate, is locked inside, and is screwed with the fixing bolt. The fixing plate is configured so that the detent rod provided from the base plate is engaged with the fixing plate.

Therefore, work such as welding is not required, deformation of the lining plate and handrail columns is prevented, it can be used repeatedly as many times as desired, and it is easy to install and remove. Since the handrail pillar can be provided by using only the through hole provided, the handrail pillar can be provided even when the lining plate is in an embedded state and the peripheral edge thereof is not open.

In addition, the walking surface base plate on the upper surface of the lining plate does not stick out as in the past, and the head of the fixing bolt is also housed in the notch in the lower part of the column, so it is not exposed to the walking surface and it is safe. In addition, since the base plate is not provided from the peripheral edge of the lining plate, it can be small in size, does not obstruct the removal of the lining plate, and is easy to handle such as transportation and storage.

[Operation] The lining plate 1 of the present invention is attached to the upper surface of the lining plate 1 only by using the through holes 6 which are provided in advance for cargo handling, such as hanging.

First, the fixing bolt 8 is loosened so that the base plate 3 and the fixing plate 4 are sufficiently spaced from each other. In this state, the fixing plate 4 is inserted into the through hole 6 on the upper surface of the lining plate 1.

At that time, the whole is tilted, and the fixing plate 4 is inserted into the through hole 6 on the upper surface of the lining plate 1 from its tip. After that, when the fixing bolt 8 is rotated to lift the fixing plate 4 upward, the lining plate 1 is sandwiched between the base plate 3 and the fixing plate 4, and the column 2 is vertically fixed.

In addition, when removing, it may be performed in the reverse order. It should be noted that when the fixing bolt 8 is rotated, the fixing plate 4 does not rotate together with the detent rod 9 and only moves up and down, and is firmly attached to the lining plate 1 side.

[Embodiment] An embodiment of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cutaway sectional view of a main part, and FIG. 2 is a plan view thereof.

Reference numeral 1 is a lining plate, and through holes 6 are provided at approximately four corners thereof for cargo handling such as hanging. Although not shown, 2 is a pillar, and a handrail pillar is provided at an appropriate position through a clamp or the like.

In the present invention, one side of the lower portion of the column 2 is cut out as shown in FIG. The base plate 3 is fixed to the lower end by welding. The base plate 3 is in close contact with the upper surface of the lining plate 1 to erect the columns.

Further, in the present invention, a through hole 5 is provided at the position of the cutout portion of the base plate 3.

Next, a fixing bolt 8 is inserted into the through hole 5, and can be inserted into the through hole 6 provided on the upper surface of the lining plate 1 below the base plate 3 so as to be locked inside and further fixed. The fixing plate 4 with which the bolt 8 is screwed is provided. That is, the fixing plate 4 is provided with the female screw hole 7 in advance.

Next, the locking plate 9 provided from the base plate 3 is engaged with the fixed plate 4.

In the case of the embodiment shown in the drawings, the engagement is carried out by forming the through hole 10 in the fixed plate 4 and inserting the stop rod 9 which rotates around the through hole 10.
A cutout portion may be formed instead of the through hole 10 and the detent rod 9 may be located in the cutout portion.

Reference numeral 11 in the drawing corresponds to the through hole 6 of the lining plate 1, and the through hole 6
A plate that facilitates positioning inside, 12 is the rear end of the base plate,
It is a reinforcing plate welded to the outer peripheral rear surface of the pillar 1.

With the above-described structure, the present invention does not require welding work and can be easily erected on the column 2 with a single fixing bolt. Moreover, the column 2 can be erected even when the peripheral edge of the lining plate 1 is not open.

[Effects of the Invention] As described above, according to the present invention, it is easy to install and remove the work, and moreover, it is economical because it can be used repeatedly as many times as possible without deforming the appearance of the lining plate and the columns. In addition, since the columns can be provided only by using the through holes on the upper surface of the lining plate, it is possible to use the lining plate in an embedded state.

Further, the base plate does not protrude from the walking surface from the peripheral edge of the lining plate to the through hole provided on the upper surface, and the head of the fixing bolt is also housed in the notch in the lower part of the column and exposed on the walking surface. Since it is not provided from the peripheral edge of the lining plate of the base plate, it is small and does not interfere with the removal of the base plate, and it is easy to carry and store.
