Description

[Detailed Description of the Invention] The present invention relates to a waterproof sheet seam expansion pressure device that continuously applies pressure to, for example, a wide waterproof sheet seam bonded portion.

Conventionally, when applying pressure to the adhesive surface of the seam of a waterproof sheet, a single roller or a large wooden hammer was used to expel the air contained in the adhesive surface into the atmosphere. I was doing it.

This work is a manual work by the operator, and in the single roller method, the air in the adhesive surface cannot be removed unless the adhesive is moved back and forth at the same location two or three times.

For this reason, it has been desired to develop a spreading pressure device that can improve the degree of adhesion by removing air from the adhesive surface by passing the adhesive surface only once.

The present invention was developed in view of the above-mentioned circumstances, and aims to provide a waterproof sheet seam expansion pressure device that can reliably expel air from the adhesive surface and greatly improve work efficiency. .

The present invention consists of a frame supported by rollers formed to be able to travel, an excitation frame to which an excitation roller and an exciter are attached, and a spring interposed between the excitation frame and the frame so that it can vibrate in the vertical direction. It is provided with an attached support member.

Below is an example of the waterproof sheet seam expansion pressure device of the present invention.
This will be explained with reference to FIGS. 1 and 2.

A frame 1 supports rollers 2, 2 at front and rear positions that are movably mounted.

In the frame 1 between the rollers 2, 2 there is a spring 9. Natsu 10. Pressure adjustment section 5 consisting of a bolt-shaped support member 8
A vibrating frame 3 is suspended from the frame 1 via a vibrating frame 3, and a vibrating device 6 consisting of a pie break and two vibrating rollers 4 are attached to the vibrating frame 3.

The support member 8 is formed into a bolt shape and has a spring 9.
Vibrating roller 4 is elastically supported by a nut 5.
It is attached so that the spreading pressure stroke of the waterproof sheet 12 can be adjusted freely, and supports the waterproof sheet 12 so that the spreading pressure can be applied to the seam bonded portion of the waterproof sheet 12 by the vibrating roller 4.

Reference numeral 7 denotes a vibration adjuster that adjusts the strength of vibration of the vibrator 6.

In this way, the waterproof sheet seam rolling pressure device of this embodiment is configured to use a dynamic rolling pressure method, whereas the conventional system uses a static rolling pressure method, and it applies rolling pressure to the sheet seams. At this time, the operator holds the handle 11 and pushes the seam of the waterproof sheet 12 in the direction of the arrow.

The vibrating roller 4 is given vibration by a pie-break vibrator 6 and is elastically suspended via a spring 9, so that it moves toward the waterproof sheet 1 12 in response to the vibration.
Move forward while applying pressure to the adhesive surface many times.

Therefore, compared to the conventional method of repeating the spreading pressure 2 to 3 times with a single roller or applying the spreading pressure manually using a wooden hammer, it is possible to significantly increase the number of times the spreading pressure is applied. Air is efficiently and sufficiently expelled from the adhesive surface portion, and adhesiveness can be improved.

Further, the work becomes easier and the work efficiency can be improved.

The strength of the vibration is controlled by the vibration regulator 7, and since rolling pressure on soft ground is ineffective, a hard plate material is placed under the seam bonding portion of the waterproof sheet 12 to apply rolling pressure.

Further, even in places where the ground is uneven, complete spreading pressure can be expected due to the vibration of the vibrating roller 4.

Note that a power source or a high-pressure air source is used as a drive source for the vibrator of the vibrator 6.

As described above, the waterproof seal 1 to the seam expansion pressure device of the present invention has the effect of reliably expelling air from the adhesive surface to improve adhesion, as well as being easy to work with and greatly improving work efficiency. It is.
