Description

TECHNICAL FIELD The present invention relates to a gutter block suitable for installation in a narrow place where heavy machinery cannot easily enter, such as a narrow road.

Most gutters are made of concrete, but some are also made of steel. Heavy, factory-produced gutters are usually transported to the construction site by truck, but in narrow spaces where it is difficult for trucks to enter, trucks are often used. The actual situation is that the materials are transported directly to the construction site from where they are parked, either by hand or by being transferred to a trolley or the like.

Since side gutters are required to have a size and structure that suit the installation location, it is necessary to prepare a wide variety of side gutters in advance according to customer requirements. Furthermore, when installing in a narrow space, it is required to be lightweight so that it can be easily carried.
SUMMARY OF THE INVENTION An object of the present invention is to provide a gutter block that can be easily carried to a narrow place by hand or by using a cart or the like.

The invention according to claim 1 provides a gutter block having a substantially U-shaped cross section, which is composed of a bottom wall portion and side wall portions on both sides of the bottom wall portion, and a gutter cover is attached to span the both side wall portions. It is removable from the wall and can be assembled together at the construction site, and the entire structure is made of steel. It is composed of a plurality of blocks each having a U-shaped surface, and the vertically adjacent blocks are characterized in that their upper and lower wall portions are removably connected by a first fastener.

The invention according to claim 2 is characterized in that, in the invention according to claim 1 , the lower end portion of the side wall portion that is divided into a plurality of parts is configured integrally with the bottom wall portion .

According to the invention according to claim 1, among the members constituting the side gutter, both the bottom wall part and the side wall part are not integrated but are divided , so that the gutter can be folded compactly and stored. Even in cramped places where it is difficult for light trucks to enter and exit, it can be easily transported to the construction site using a trolley such as a handcart, or directly carried by hand for assembly and construction.

Further, in the invention according to claim 1 , after stacking two or more steel blocks, each block has rigidity by connecting the vertically adjacent blocks using the first fastener. This reduces weight and ensures strength, making it difficult to collapse or deform.

Furthermore, the block in the invention according to claim 1 may also be assembled such that the connecting part connects, for example, the outer ends of the wall parts, and the opening faces inward, but preferably, the connecting part connects the outer ends of the wall parts. The inner ends of the parts are connected and assembled so that the opening faces outward and the inner surface is flat. By assembling the opening so that it faces outward, the first fastening tool does not come into contact with rainwater, etc. in the gutter, making it less likely to rust, and making it difficult for rainwater, etc. to stagnate. This will allow rainwater to flow smoothly inside.

According to the invention according to claim 2 , at the time of construction, after installing the lower end of the side wall part and the bottom wall part integral with the lower end part in the side gutter, the blocks constituting the other side wall parts are installed on the lower end part of the side wall. However, by positioning and installing the lower end of the side wall integrally with the bottom wall in the side gutter, the members constituting the other side walls can be easily and reliably assembled by positioning. I can do it.
