Definitions
- the sector of the technique of this invention is that of the manufacture of construction tools, and particularly hand tools for spreading concrete in formwork.
- the supply of concrete to the works is normally done by pumping a large amount of material in a pasty liquid state, which causes the spread to be irregular, so it is necessary that it be done manually using tools with a handle and a surface of material drag.
- the present invention aims at a tool for spreading concrete in works, which overcomes the drawback of traditional tools by adding skates or drag wheels, as we will see below.
- Figure 1 shows a schematic view of a tool according to the invention
- Figure 2 shows a view similar to the previous one, in which the fixed skates have been replaced by wheels
- Figure 3 shows a detail of the drag blade in a variant in which different drag heights are provided, in line with the desired formwork height
- Figure 4 shows a tool as it is known in the state of the art
- the dragging blade is shown indicated by 1 having a mouth 2 intended to support a stick / handle or handle 3.
- an anti-engagement device is provided on both sides of the drag blade 1.
- the 'anti hitch' drag device has two possible solutions, a first one by fixing an element 4 in a way that is integral to the blade 1, without causing serious inconvenience to the friction produced by the drag on the base, due to the lightness of the tool, on the one hand, and to the lubricating effect produced by the concrete poured in its pasty state.
- Said piece or drag skate 9 can take, for example, the shape of a disk, although it could also take on a lenticular shape, or any other non-angled one.
- the second solution involves the addition of a rotation shaft 12 to which rotating wheels 6 are fixed instead of the indicated skates.
- the positioning height 7 of the rotating wheel 6 or drag skate 9 can be optionally adjustable.
- the drag blade 1 has a wall 13 located at a certain angle on said blade, which makes it possible to prevent the concrete being distributed from flowing above said blade 1, recovering the initial position, which would make the work useless or more difficult.
- a top flap 14 is provided to give consistency to the piece, as well as braces 15 that allow to better orientate the mouth 2 of the handle 3.
