Description

The present invention relates to an asphalt roofing tensioning device capable of safely, quickly and easily affixing asphalt roofing to wall surfaces and other rising parts in asphalt waterproofing construction.

Conventionally, asphalt roofing is applied to a rising portion such as a wall surface by a method as shown in FIG. In the figure, H is a wall surface, 12 is a roll of asphalt roofing, and 13 is an asphalt roofing affixed to the wall surface H. This method is generally called roll-up, and the operator uses the other hand to hold molten asphalt that is held in the handle between the wall H and the back of the asphalt roofing 13 while holding the roll 12 with one hand. Sprinkling in the A direction, while visually confirming that the molten asphalt is evenly distributed over the entire back surface of the asphalt roofing 13, the roll 12 is rotated while being pushed up by hand, and the asphalt roofing 13 is pressure-bonded to the wall surface.

Since this method is carried out while visually observing the state of spraying of the molten asphalt, there is no unpainted portion of the molten asphalt on the backside of the asphalt roofing, so there is no unbonded portion between the asphalt roofing 13 and the wall surface H, and high waterproof quality can be realized.
However, this method requires a complicated and sophisticated operation of holding the asphalt roofing roll 12 with one hand, moving the roll 12 upward while pressing the molten asphalt with the other hand, and crimping it. Requires advanced skills.
When the asphalt roofing flexibility is high, the difficulty of the work is further increased. When winding and pasting, since the work is done by hand, when the sheet to be pasted is pressure-bonded from the surface with a glove to which asphalt is adhered during construction, the asphalt adheres to the finished surface and a beautiful finish cannot be obtained.
In addition, there is a risk that the molten asphalt will scatter to the hand holding the asphalt roofing and cause burns.

For this reason, there has been proposed a so-called bukkake pasting method in which molten asphalt is applied to the back surface of asphalt roofing and is crimped to a wall surface or the like. Since this method is simple in content, it has high construction efficiency and does not require any special skill. However, the melted asphalt sprayed on the back surface of the asphalt roofing is likely to be cooled before press-bonding and a necessary degree of adhesion cannot be obtained. In asphalt roofing, asphalt roofing is usually crimped by hand. At this time, the sheet is crimped from the surface with gloves with asphalt attached during construction, and the asphalt adheres to the finished surface and a beautiful finish cannot be obtained. There is a problem.
On the other hand, there is a risk of burns on the hands held when applying molten asphalt to asphalt roofing.

In addition, a method has also been proposed in which the reverse side of the asphalt roofing is melted by a burner and then crimped to a wall surface, etc., but even with this method, the melted asphalt is cooled before crimping, and the necessary adhesion cannot be obtained. is there.
The following documents exist in relation to the present application.
JP2005-213981 JP 2005-146654 A JP-A-2004-270383 JP 2000-234421 A JP-A-11-190108 JP 07-042326 A

An object of the present invention is to realize an asphalt roofing stretching device capable of safely, quickly and simply attaching asphalt roofing to a wall surface or other rising part in asphalt waterproofing construction.

  The present invention is an asphalt roofing tensioning device for pasting, while visually confirming that the asphalt melted and melted throughout the entire back surface of the asphalt roofing is applied when asphalt roofing is applied to the wall surface, Tensioning means for raising and lowering the wall surface to hold the asphalt roofing, a supporting means for the tensioning means, and a pressing means for allowing the asphalt roofing to be pressed against the wall surface by being able to move forward and backward in the wall surface direction and pressing the tensioning means in the wall surface direction. And an asphalt roofing tensioning device that cooperates with the pressing means to move the tensioning means upward through the support means, and to solve the above-mentioned conventional problem It is.

Further, in the asphalt roofing tensioning device, the tensioning means includes a pressing roller and a rotating shaft that rotatably supports the pressing roller, and the supporting means suspends and supports the rotating shaft at both ends. The pressing means may be constituted by a rod that is connected to the frame and has wheels that can travel on the floor surface, and the auxiliary means may be constituted by a hanging metal fitting that can be gripped.

Furthermore, in the asphalt roofing stretching apparatus, the frame body may be formed of a U-shaped metal fitting, and a foot plate for applying an operator's foot pressure may be provided at the end of the rod.

The invention of the present application enables the asphalt roofing to be safely, quickly and easily crimped and affixed to the wall and other rising parts without requiring a high level of skill in asphalt waterproofing construction. The beauty of both can be improved and the construction cost can be reduced.

  In the present invention, various modes can be considered for the tensioning means for raising and lowering the wall surface and holding and pressing the asphalt roofing. It is desirable that the tensioning means is composed of a pressing roller and a rotating shaft that rotatably supports the pressing roller. The supporting means for suspending the tensioning means having the above-described configuration is, for example, a U-shaped frame, and the rotation shaft is sandwiched between both ends of the frame.

In addition, as a pressing means that can advance and retreat in the wall surface direction and press the stretching means in the wall surface direction to press the asphalt roofing against the wall surface, any member that can transmit the pressing force by the operator may be used. In general, a rod-shaped rod is easy to adopt. The operator presses the supporting means through the rod, and is driven so that the roller moves upward while pressing the asphalt roofing on the wall surface. For this reason, the positional relationship between the rod as the pressing means and the U-shaped frame needs to be a relationship that promotes the pushing-up operation. Normally, the rod is moved inward and outward by 90 degrees with respect to the surface formed on the frame. It is desirable to install at an angle of
The rod requires some traveling means to prepare for advancement and retreat in the wall direction, but a wheel is desirable from the viewpoint of functionality. Also, since the pressing operation is performed by the operator's foot, if the operator has a foot plate such as a foot plate on the rod, the operation becomes easy.
It is desirable that the rod can be expanded and contracted according to the height of the wall surface to be constructed.

When the operator presses the rod as the pressing means, the roller presses the asphalt roofing on the wall surface, but the roller moves upward on the wall surface only by pressing on the rod. Absent. Therefore, if the frame is lifted by the assisting means and urged upward, the roller starts traveling upward while pressing the asphalt roofing against the wall surface. Although such an assisting means can be variously configured, it is configured by a member that is freely connected to the frame so that the operator can lift the frame as easily as possible. As the member, a rod-like material, a chain, a string, etc. can be handled, but a rod-like material is used to operate the frame body while slightly cooperating with the pressing means, and at the end part in consideration of workability. It is desirable to form a handle.

An embodiment of the present invention will be described below. FIG. 1 is a perspective view of an asphalt roofing tensioning device according to one embodiment of the present invention.

It is composed of a U-shaped frame that suspends and supports 1b at both ends. The pressing means 3 includes a rod 3a connected to the frame 2 and a wheel 3b that enables the rod 3a to travel on the floor surface. The rod 3a can be stretched and stretched, and can be fixed to the desired length by the stopper 3c. By adopting such a configuration for the rod 3a, the length of the rod 3a can be set to an appropriate length corresponding to the height of the wall surface to be constructed, and workability is improved. Also, a foot plate 3d is provided at the end of the rod 3a as a footrest for applying the foot pressure of the operator.

In the figure, the posture of the worker is that the asphalt roofing 13 is placed on the foot plate 3d, grips the handle 4a with one hand, and is wound around the pressing roller 1a by a burner (not shown) with the other hand. The reverse side is turned from the direction of arrow A to melt the asphalt on the surface.

After visually confirming the melting state of the asphalt, as shown by an arrow C, the foot plate 3d is pushed in the wall surface H direction with the foot and the apparatus M is pushed in the wall surface H direction. In conjunction with this operation, the operator lifts the handle 4a in the direction of arrow B, that is, upward. By these operations, the heat melting surface on the back surface of the asphalt roofing 13 is pressed against the wall surface H, and the unmelted surface on the back surface of the asphalt roofing 13 is sent to the upper part of the pressing roller 1a and enters the operator's field of view. Thereafter, the asphalt roofing affixing operation to the wall surface proceeds by repeating the above procedure. In the above description, the reverse side of the asphalt roofing is melted by scrubbing with a burner, and this portion is pressure-bonded to the wall surface. In the above construction work, the optimum length of the rod as the pressing means 3 is selected according to the height of the worker and the height of the construction site.

  According to the present invention having the above-described configuration and operation, even those who do not have special skill can perform asphalt roofing on a rising portion such as a wall surface safely and efficiently while maintaining good construction quality. In addition, since the roofing is pressure-bonded not by hand but by a pressing roller, the finished surface is less likely to get dirty and a beautiful finish is obtained, which often contributes to a reduction in the total cost of construction.
