Description

[Detailed Description of the Invention] The present invention relates to an elastic dam frame that can easily adhere to irregularities on a foundation surface.

When pouring concrete onto a foundation surface, conventionally, as shown in Fig. 1, a weir frame 2 assembled from plates is installed on the foundation surface 1, and concrete is supplied into the weir frame 2 by appropriate means. are doing. but,
If the foundation surface 1 is uneven, the lower surface of the weir frame 2 is straight, so a gap 3 will be created between the lower surface of the weir frame 2 and the foundation surface 1, and the concrete 4 supplied to the weir frame 2 will be
There was a risk that it would leak out from the third floor. Therefore, it is difficult to work quickly, which increases the construction cost and construction period, and the weir frame 2
It was difficult to manufacture complex shapes that matched the foundation surface, and there were problems such as poor workability.

The object of the present invention is to provide an elastic dam frame that can easily adhere to the irregularities of the foundation surface, thereby enabling quick and efficient work.

According to the present invention, by placing a weight on the elastic dam frame body, the lower surface of the elastic dam frame body can be easily brought into close contact with the unevenness of the foundation surface, so the work can be done quickly. Installation and removal of the weir frame is easy and workability is good.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In the figure, reference numeral 5 denotes an elastic dam frame main body, which is made of a suitable elastic material and has an endless and bottomless shape.
The cross-sectional shape of the elastic dam frame main body 5 can be selected from any polygonal shape such as a triangle or quadrangle, or any shape such as an ellipse, a cylinder, or a sphere, and the planar shape of the concrete supply section also corresponds to the outer periphery of the concrete to be poured. Depending on the shape, it can be made into any shape such as polygonal or cylindrical. Furthermore, 6 in the figure is a weight, and the elastic dam frame main body 5
It is placed on the upper surface of the elastic dam frame main body 5 so that it can come into close contact with the unevenness of the foundation surface 1.

When pouring concrete, place the elastic weir frame main body 5 at a predetermined position on the foundation surface 1, place a weight 6 on the main body 5, and place the lower surface of the elastic weir frame main body 5 against the foundation surface 1. The elastic weir frame main body 5 is supplied with concrete using a concrete pump or the like. Since the lower surface of the elastic weir frame main body 5 is in close contact with the foundation surface 1, the concrete 4 supplied to the elastic weir frame main body 5 does not flow out from the main body 5.

It goes without saying that the elastic dam frame body of the present invention may be implemented in a solid or hollow form, and that various other changes may be made without departing from the gist of the present invention.

According to the elastic dam frame of the present invention, an elastic body that can be deformed so as to easily adhere to the unevenness of the foundation surface is used, so that the lower surface of the elastic dam frame body can easily adhere to the foundation surface, so that it can be easily removed from within the dam frame body. Concrete does not flow out to the outside, and therefore work can be carried out quickly, so the construction period is shortened and the construction costs are reduced.

Workability is good because the elastic dam frame body can be easily installed and removed.

Even if the framework shape is complex, it can be easily applied.
Advantageous for concrete with complex outer periphery.
Various excellent effects can be achieved.
