Description

[Detailed explanation of the idea] This idea relates to floorboards.

Conventionally, in a floorboard made up of parallel vertical bars and a connecting member that connects mutually adjacent vertical bars, the shapes that make up the vertical bars and the shapes that make up the connecting members have different cross-sectional shapes. Since two types of shapes are used, two types of molds are required to make the floorboards, which increases equipment costs and increases the cost of 1. There was a problem in that manufacturing the floorboards was troublesome and expensive.

The purpose of this invention is to solve the above problems, and to make the vertical beams and connecting members that make up the floorboards from one type of material with the same cross-sectional shape, and to use one type of metal for manufacturing the floorboards. The object of the present invention is to provide a floor board that requires only the installation of molds, which reduces the equipment cost very low, and allows the floor board to be manufactured easily and at low cost.

, this invention is a distant relative of the above objectives by: 1. In a floorboard consisting of parallel vertical bars and a connecting member that connects mutually adjacent vertical bars, the vertical bars and the connecting member are made of one type of shape material having the same cross-sectional shape,
The profile has first and second parallel to each other having substantially the same width.
Opposing walls, a connecting wall that has approximately the same width as the width 1 of these opposing walls and is connected at right angles to the center widths of both opposing walls, and a central part of opposing surfaces of the first and second opposing walls. It is equipped with engaging protrusions that protrude inwardly on both the left and right sides of the side, and a fitting groove formed between these engaging protrusions and the connecting wall, and the vertical beam is long. The connecting member is made of a short profile and the first and second opposing walls are vertical, whereas the connecting member is made of a short profile and the first and second opposing walls are vertical. The gist of the present invention is a floorboard in which both side edges of the first and second opposing walls of the connecting member are fitted into grooves inside the first and second opposing walls of the vertical beam.

Next, an embodiment of this invention will be described based on the drawings.

In the drawing, the floorboard A according to this invention has vertical bars B arranged in parallel, vertical bars B adjacent to each other, as shown in FIG.
It consists of a connecting member C that connects B to each other,
FRP in which the vertical beam B and the connecting member C have the same cross-sectional shape
It is made from one type of profile P made of drawn material.

As shown in FIG. 1, the profile P has first and second opposing walls 1, 1 that are parallel to each other and have substantially the same width, and a width that is substantially the same as the width of these opposing walls 1, 1. and a connecting wall 2 connected at right angles to the width center portions of both opposing walls 11;
Engagement convex portions 31, 32, 33, 34 provided inwardly protruding portions on both left and right sides near the center of the opposing surfaces of the opposing walls 1, 1
and fitting grooves 41, 42, 43, 44 formed between these engaging protrusions 31, 32, 33, 34 and the connecting wall 2.
It is equipped with

In addition, bulges 6, 6 having a corrugated cross section are provided on the outer surfaces of the first and second opposing walls 1, 1, respectively.

The vertical beam B is made of a long profile P and is arranged so that its first and second opposing walls 1, 1 are horizontal, whereas the connecting member C is made of a short profile P and its first and second opposing walls 1, 1 are horizontal. The first and second opposing walls 1, 1 are arranged vertically,
As shown in FIG. 3, both side edges 51, 52, 53, 54 of the first and second opposing walls 1, 1 of the connecting member C are vertical bars B,
Recesses i41, 42 inside the first and second opposing walls 1, 1 of B
It is fitted within 43.44°.

Here, the cross-sectional corrugated bulge portion 6 on the upper surface of the vertical bar B has an anti-slip effect.

The area of floorboard A can be easily increased or decreased by changing the length of vertical bar B or increasing or decreasing the number of vertical bars B and connecting members C. Increasing the number has the advantage that the strength of that part can be particularly increased.

In addition, by fitting the vertical beams B and the connecting members C that make up the floorboard A as described above, and gluing them together with an adhesive or tightening them with bolts and nuts,
° The strength of the floorboard A can be increased.

As described above, the floorboard according to this invention is made of one type of profile P in which the vertical beams B and the connecting members C that make up the floorboard A have the same cross-sectional shape. , it is only necessary to arrange the vertical bars B made of long profiles P in parallel and fit the connecting member C made of short profiles P horizontally between the adjacent vertical bars B, B, so that the floorboard A Very easy to manufacture.

In addition, since the vertical beam B and the connecting member C are made of one type of profile P having the same cross-sectional shape, it is sufficient to install one type of mold, and therefore the equipment cost is very low. As a result, the floorboard A can be manufactured at low cost.
