DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a steel lining plate used to construct work floors for supporting heavy objects, floors for bridges, temporary roads, and the like.

[0002]

2. Description of the Related Art As a conventional steel lining plate used for the above purpose, for example, a steel lining plate using channel steel or a steel lining plate using H-shaped steel is generally used. . These have a structure in which many shaped steels are welded or joined together with bolts and nuts. There are two types of surfaces, which are asphalt pavement and steel surface, and the back surface is rubber pad or non-slip. The ones that are used are generally used.

For example, as shown in FIG. 8, channel steel 11-1.
Which are connected in parallel by bolts / nuts, reinforcing plates, etc. to form a main body 11 and asphalt pavement 11-2 is applied to the upper surface of the main body, or as shown in FIG. The main body 12 is formed by arranging several 1's in parallel and welding their joint surfaces to integrate them.
Such as those subjected to asphalt paving 12-3 has been known to.

[0004]

Since the conventional general steel lining plate as shown in FIGS. 8 and 9 is integrated by welding or connecting many shaped steels with bolts and nuts, the number of processing steps is increased. Since it is heavy and has many constituent members, it becomes a heavy object and requires a great deal of labor and time for transportation and installation. In addition, since the conventional one has a closed cross-section structure, the inside cannot be seen at all and the surface structure is complicated, so it is not possible to fully check the condition of the welded part, the looseness and damage of the bolts and nuts, etc. , Maintenance of durability and strength is difficult. Therefore, it has been necessary to pay sufficient attention to safety in the conventional steel lining plate.

In view of such problems of the prior art, the present invention has a relatively simple structure and is excellent in strength and durability.
Moreover, the present invention intends to provide a steel lining plate that can reduce the number of processing steps and the weight.

[0006]

A steel lining plate according to the present invention uses shaped steel such as box-shaped, H-shaped, and groove-shaped cross sections for a main girder and a transverse girder, and uses a steel buckle plate as a floor plate. The gist is that the main girders made of various shaped steels are arranged in parallel at intervals, and the transverse girders made of various shaped steels are arranged at both ends and the central part of the main girders. A main body frame having two space portions is formed by welding to a girder, and the bottom surface has a triangular shape in the two space portions, and the triangles are provided on both sides thereof.
The height of the apex side of the bottom of the shape is almost the same as the height of the cross beam,
There is a bent piece whose height on the bottom side of the bottom is shorter than that on the top side.
Then, fold the steel buckle plate that is the same size as the space
Place the body frame so that the upper surface of the bent piece is flush with the upper surface of the main girder.
It is attached by welding, and a resin foam material or a filler made of concrete or asphalt is placed flush with the upper surface of the main body frame on the buckle plate , and an asphalt layer or concrete layer or resin having an appropriate thickness is placed thereon. It is a steel lining plate obtained by applying a pavement made of a foam layer to the entire upper surface of the main frame.

[0007]

The main girder and the transverse girder are made of box-shaped steel, H-shaped steel and grooved steel in cross section, and these members are arranged vertically and horizontally to form the main frame. This main body frame is constructed by welding transverse girders to both ends of two main girders arranged in parallel at a required interval to form a rectangular frame body, and further to the center of the frame body, the lateral sides of the both ends. Since the same transverse girder is welded in parallel with the girder, the strength of the main body frame is sufficiently maintained. In addition, since the floor plate is made up of steel buckle plates that are attached by welding both ends to the end and the center transverse beam in the left and right space of the body frame, the wheel load acting on the body frame is It can be resisted by the film force of the buckle plate, and excellent tensile strength can be obtained. Also,
Since the filling material is filled only in the buckle plate,
Even if concrete or asphalt is used as the filling material, it is lighter than the conventional steel lining plate due to the effect of reducing the weight of the steel material due to the reduction in the number of components, and especially when the resin-based foam material is used as the filling material. , The weight of the entire lining plate is greatly reduced. Moreover, since the bottom surface of the lining plate is open, the internal condition can be easily checked, which is advantageous in terms of maintenance. Further, since the number of constituent members is reduced, the number of processing steps is small and the assembly is relatively easy.
