DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-slip device for a lining plate, and is used to safely and reliably prevent the lining plate from slipping when the lining plate is arranged at an angle.

[0002]

2. Description of the Related Art Conventionally, when constructing a foundation or a building such as a concrete building or bridge, or when constructing a bank or performing a work for passing a road through a cut-through or the like, as shown in FIG. Then, the ground a was excavated, and sheet piles b and b 'were driven around the inside to prevent the ground a from collapsing. Moreover, an appropriate number of piles c are driven into the excavated ground a, and a horizontal joining material d is erected between the piles c, c, and a vertical brace material e is erected diagonally between the piles c, c. And large reinforcing members f, f are laid in a substantially horizontal direction on the upper surfaces of the piles c, c, and a horizontal brace material g is laid between the large pulling materials f, f to reinforce the piles c. The gantry K was constructed by arranging an appropriate number of joists h, h... On the upper surfaces of the large pulling members f. An appropriate number of joists h ', h'... Are provided with an ascending gradient θ between the gantry K and the ground a surrounded by the sheet piles b and b ', and the joists h', h '. Joists h, h of the gantry K
Are covered with a lining plate i formed of a steel plate or the like, thereby forming a scaffold and ensuring the safety of work in construction. In addition, rebar or angle iron was directly welded to the lining plate as slip prevention means.

[0003]

As shown in FIG. 8, a gantry K is constructed inside the excavation point of the ground a, and the gantry K is located between the gantry K and the ground a surrounded by the sheet piles b and b '. A lining plate i, which covers the upper surface of the joist members h ′, h ′.
Since i ... is laid on the inclined surface i ₁ of the upslope theta, easily slides into the case and engaging the work vehicle is working on a slope, sometimes such a concrete mixer truck, etc. is sliding and accident risks Met. In addition, there is a problem in the method of directly using the lining plate in the method of welding directly to the rebuilding plate.

[0004] Therefore, an object of the present invention is to provide a slide preventing device for a lining plate capable of preventing the sliding and performing the work safely, and an object of the present invention is to repeatedly use the lining plate.

[0005]

[0006]

The sliding is prevented by a plurality of non-slip projections provided on the upper surface of the base component which is mounted on the inclined surface.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. Reference numeral 1 denotes one or a plurality of, for example, three vertical crosspieces as base parts. The vertical crosspiece 1 has, for example, a gantry K as shown in FIG. Joists h ', h' erected between the enclosed ground a
... mounted by polymerizing the upper surface of the lining plate i in ascending slope θ covering the upper surface of, it has an inclined surface i _1.

Reference numerals 1a denote locking projections provided on at least lower surfaces before and after the vertical rails 1, 1 located on the left and right as base components. Holes provided at four corners of the lining plate i are provided. vertical crosspieces 1 by engaged into i in ₂ lining plate i
It is superimposed and attached to the upper surface of the. The length of the locking pin 1a is formed to be a length L sufficient to lock the vertical beam 1 to the lining plate i. Engaging the longitudinal crosspieces 1 as the base component for attachment to lining plate i is necessarily the base part as a hole i within ₂ provided on the lower surface of the longitudinal crosspieces 1 the locking projections 1a to lining plate i in It is not limited to insertion, but it is possible to engage with the vertical bar 1 by using bolts, covering the lining plate, or projecting locking pieces on the joists h, h '. lining plate i may be prevented from slipping down from the inclined surface i ₁ by stopping.

Reference numeral 2 denotes a cross section as shown in FIGS. 1 to 3, for example.
This is a substantially mountain-shaped non-slip ridge.
A plurality of materials are intersected with the upper surface of the materials 1, 1, 1 in the traveling direction a.
It is erected at intervals. This non-slip ridge 2 is shown in FIG.
3 to FIG. 3, the L-shaped steel material is
It is formed by welding to
The cross-sectional shape of is not limited to a substantially mountain-shaped cross-section, and is shown in FIG.
As shown in FIG. 5, the cross section is square, and FIG.
L-shaped section as shown in FIG.
The length so that it fits the outer peripheral surface of the
It may be formed in a plane I shape. And the anti-slip ridge 2,
The predetermined interval between the two is that the work vehicle ₁Slowly
The optimal distance is such that it can run naturally. And non-slip
The height L 'of the ridge 2 does not hinder the running with respect to the upward slope θ.
And the wheels are locked enough to prevent sliding
It is formed at a sufficient height. The non-slip ridge 2 has a large load
Even if F is applied from above, it disperses the load and demonstrates rigidity
And become structurally robust.

[0010] One embodiment of the present invention has the above structure,
For example, on the upper surface of joists h and h 'having an ascending angle θ provided between the gantry K and the excavated ground a, the anti-slip device of this embodiment is provided in the hole i ₂ provided in the lining plate i. 1,1
1 can be quickly and reliably mounted on the upper surface of the lining plate i by engaging a locking projection 1a provided on the lower surface of the lining plate i.

The lining plate i has an inclined surface i _{1 having} an upward slope θ.
Even in the case of being formed of a steel plate, a plurality of non-slip ridges 2 are provided at predetermined intervals on the three vertical rails 1, 1, 1 as base parts so as to intersect in the traveling direction a. since it is provided, by which the anti-slipping protrusions 2 is sufficiently locked on the work vehicle, sliding at the time of lifting the slope portion i ₁ is reliably prevented. In this case, even if a large load is applied from above, the non-slip ridge 2 disperses the load, exhibits rigidity, and is structurally robust.

A plurality of non-slip ridges 2 provided at predetermined intervals are fixed to the upper surfaces of, for example, three vertical bars 1, 1, 1 as examples of a base part by welding or the like. So
The easily slidable clay or concrete adhering to the wheel at the construction site falls from the gap surrounded by the non-slip ridges 2 and 2 and the vertical rails 1 and 1 and does not adhere to the wheel for a long time.
Therefore, sliding caused by the adhesion of clay or concrete to the wheels is prevented. Moreover, the clay and concrete attached to the anti-slip ridge 2 can be easily washed off by washing with water.

[0013] after use by withdrawing the locking projection 1a from hole i ₂ provided in the lining plate, it is possible to remove the sliding prevention device of the present embodiment easily from lining plate i.

In the above embodiment, a plurality of vertical rails 1 are used as base parts on which the non-slip protruding strips 2 and 2 are erected. However, the base parts are not necessarily limited to the vertical rails 1, The use of a plate or a perforated plate is also within the scope of the present invention.

Although the anti-slip device of the above embodiment is formed to have a size substantially corresponding to the size of one lining plate i, it is applied to a plurality of lining plates i as long as it is portable. By forming the anti-slip device to have a size substantially coincident with each other, the anti-slip device may be attached to a plurality of lining boards i at a time, and may be provided for use.
