Description

[Detailed explanation of the invention] Industrial application field This invention relates to a tool for spreading roll materials, and is particularly applicable to spreading roll materials such as roofing materials on floors etc. with molten pitch. It is a convenient device for spreading things.

BACKGROUND TECHNOLOGY In general, in construction work, in order to waterproof concrete floors and roofs, high-temperature molten asphalt (pitch) is poured onto the floor surface, and roofing material is sometimes spread over it. Conventionally, this roofing installation work has been carried out by one worker 7, for example, as shown in FIG.
Immediately after that, another worker 10 bends down and uses both hands to apply the roofing material roll 4 to the pitch 8.
It was moving forward (expanding) while expanding upwards.

Problems to be Solved by the Invention However, according to the above-mentioned conventional roofing installation work, the heated pitch 8 applied by the worker 7 is scattered by gusts of wind, etc., and adheres to the face and hands of the following worker 10. In addition to this, the worker 10 has to move forward while unfolding the roll 4 with both hands in a crouched position, which tends to cause fluctuations in the unfolding force of the roll.
There were disadvantages such as being easily fatigued and prone to lower back pain if continued for a long time.

The purpose of this invention is to eliminate the above-mentioned disadvantages.

Means for Solving the Problems In order to solve the above-mentioned problems, this invention has been developed to extend the roll object by connecting an arc-shaped body that can come into contact with the outer peripheral surface of the roll object and a handle that pushes the arc-shaped body forward. The tool is constituted by a rolled object, in which a rod of a predetermined length is connected with arcuate bodies perpendicular to both ends thereof, and a handle of a predetermined length is attached orthogonally to the approximate center of the rod. A roll object constituting a spreading tool and further comprising a gutter-like body of a predetermined length curved in the width direction and a handle of a predetermined length connected orthogonally to the substantially central part of the back surface of the gutter-like body. It consists of a spreading tool.

Effects In the configuration of this invention described above, when the handle is held with both hands and the arc-shaped body or trough-shaped body is applied to the outer peripheral surface of the rolled object and the handle is pushed forward, the rolled object will be moved by the curved part of the arc-shaped body or trough-shaped body. It rolls and spreads while being held down.

Embodiment An embodiment of this invention will be described below based on the drawings. FIGS. 1 and 2 are perspective views showing the first embodiment, and FIGS. 3 and 4 are perspective views showing the second embodiment, respectively.

In FIGS. 1 and 2, 1, 1 is an arc-shaped body made of a pair of wire metals curved at a predetermined curvature;
3 is a rod of a predetermined length with the arcuate bodies 1, 1 fixed perpendicularly to both ends thereof, and 3 is a handle of a predetermined length that is connected orthogonally to the substantially central portion of the rod 2. The curvature of the arc-shaped body 1 is the same as that of the rolled roofing material 4.
(See Figure 3) is approximately the same as the maximum curvature when it is expanded and the length is appropriate, but it is too short, less than 1/4 of the circumference of the roll 4,
Alternatively, it is not preferable if it is too long, such as one-half the circumference or more. Further, the handle 3 has a length suitable for being held by a worker in a standing position and allowing the arcuate bodies 1, 1 to come into contact with the roll object 4 placed on the floor or the like. The roll 4 is configured as a roll having a predetermined curvature by winding roofing material of a predetermined length and width around a mandrel. Further, 5 is a reinforcing rod for connecting and reinforcing the handle 3 and the rod 2 at diagonal positions.

The rod body 2 and the handle 3 may each have a configuration that can be expanded and contracted in the axial direction, and although the arcuate bodies 1 and 1 are a pair, they may be a single piece or a plurality of three or more pieces, and the material is not limited to wire metal, it may be a pipe material or a plate, and its structure may also be one in which a plurality of rollers are arranged in a curved manner.

FIGS. 3 and 4 show a second embodiment in which a substantially central portion of the back surface of a gutter-shaped body 6 having a predetermined length curved in the width direction is connected to one end of the handle 3 having the same structure as the first embodiment. This is an example. The gutter-shaped body 6 is curved with substantially the same curvature as the curvature of the roll material 4, like the arc-shaped bodies 1,1.

The operation of the above embodiment will be explained with reference to FIG. 5. During roofing installation work, one worker 7 moves forward while applying pitch 8 to the floor surface 9 with a brush 11, etc., and immediately after that, rolls a The object 4 is placed so that it can roll, and another worker 10 moves the first object so that the arc-shaped bodies 1, 1 (or the gutter-like object 6) abut the outer peripheral surface of the rolled object 4 from diagonally backward. Or, hold and operate the handle 3 of the second embodiment with both hands, and
Push handle 3 forward (towards worker 7). By this operation, the rolled object 4 rolls forward and unfolds while being held by the arc-shaped bodies 1, 1 (or the gutter-shaped body 6), and uses the pitches 8 sprinkled on the floor surface 9 as an adhesive to create a floor surface 9. It sticks to. Therefore, since the worker 10 works in a standing position, even if the pitcher 8 is scattered, the heated pitcher 8 will not be exposed to the heated pitcher on the face or hands as compared to a crouched position, and therefore, there will be no burns. You won't have to strain yourself or hurt your lower back.

As is clear from the above description, the present invention is not limited to roofing installation work, but can also be used to roll out rolled objects such as carpets and carpets, and to roll other log materials. can.

Effects of the Device According to the device described above, the arc-shaped body or the gutter-shaped body is brought into contact with the outer circumferential surface of the rolled object placed on the floor, etc., through the handle that can be held by the worker while standing. Since the object can be unfolded and moved forward, it is possible to prevent subsequent workers during roofing installation work from being exposed to molten pitch and getting burnt on their faces and hands. Since the roll material is held and rolled, the force is evened out and good tension can be achieved, and fatigue and lower back pain can be prevented. It's convenient.
Furthermore, the structure is simple, easy to manufacture, and can be provided at low cost.
