Description

The invention relates to a method for gluing roofing material and similar material in roofing using a bituminous top layer as a bonding agent.

A distinctive feature of the proposed method is that the roofing material and a similar material are heated to soften the coating layer from the glued side.

Since the roofing material is asphalt coated on both sides with a layer of refractory bitumen, as a result of using this layer as an adhesive, an insulating carpet of asphalt with thin, approximately 0.5 mm thick layers of adhesive is obtained.

The proposed method of gluing the ruberoid has the following advantages.

Due to the small thickness of the bonding layer, a weather-resistant carpet will be obtained. It must be casey and elastic due to the uniformity of the layer distributed over the entire area of the coiled material forming the hematical carpet.

The covering layer of roofing material, due to its use as an adhesive, frees builders from preparing the mass for gluing the web material at the work site.

The coating layer of roofing material is applied to asphalt, under factory conditions, with careful inspection and selection of the mass that meets the conditions imposed by the conditions.

In this way, a material similar to roofing material, i.e., glassine coated with a bituminous mass, can be made, giving it a different softening temperature for the corresponding samples.

The author's experiments on gluing ruberoid samples using a coating layer showed that this does not require cleaning the roofing material from talc dressing, since the talc particles during heating (the coating layer) are enveloped in mass and play the role of a filler in the future. Testing of this splice on the gap gave the best results compared to gluing in the usual way.

For a rational implementation of the described method, a device is presented, shown in a schematic cross-sectional drawing.

The device has a metal frame 1 mounted on four wheels 2. The wheels are fitted with rubber tires so as not to harm the roll material over which it has to move. In the upper part of the frame there are two bearings 3 in which the shaft 4 is placed with the web material wound on it prepared for the label. To maintain the roll in a tightly wound state and to prevent the roll from spinning, regardless of the movement of the device, springs must be fitted that create tension on the roll material when unwinding from the roll. On the axis 6 of the device there are two rods 7, which can freely vrach, around this axis. At the end of the rods 7, a heavy roller 8 is attached producing rolling of the glued web material. In its inoperative state, the roller, as shown in the drawing by the arrow, is mounted on a spring support 9, fixed on each of the transverse frames of the base frame U.

Part of the supporting wheels are mounted on the shaft 6, of which the two extreme wheels 10 are provided with flanges on the outside, which serve to maintain the direction of the web material during labeling, and the middle wheels are only supporting the web material. On the shaft 12, as well as on the shaft 6, the wheels 11 are mounted.

Thus, the rolled material, the descent from the roll wound on the shaft 4, bends around the shaft 12, the passage through the wheels //, bends around the shaft 6, the passage through the wheels 10, after which it falls under the roller 8.

All the way, the web material from roll to carpet is in a tight state.

In the passage of the web material from the shaft 12 to the shaft 6, the covering layer of the web material is heated to boiling by means of an electric heater 13 placed under this section. The heater consists of several independent sections, due to which it is possible to control the degree of heating of the covering material of the web material. The heating of the upper coating layer of the already pasted material on which the sticker is made is carried out by the electric heater 15, divided into sections as well as the right heater. The electric heater 15 is provided with wheels 17, which limit the approach of the heating grid to the ruberoid carpet.

The upper and lower heaters 13 and 15 are interconnected by a system of levers, making it possible for the knob 19 to bring and remove the heaters from the coiled material heated by them and taki1M by adjusting the degree and time of heating.

The drawing shows a device with a manual movement, it is possible to construct it with a mechanical movement by installing a small electric motor with a worm gear on one of the leading axes.

With a manual pull device, a device can be designed to automatically adjust the heating of the covering layer of the web material, depending on the speed of the device. Mechanical movement of the device of such an automaton is not required, since the speed of movement will be constant and uniform, and adjustment will be made manually, depending on the brand and thickness of the covering layer of the roll material, which will be subject to labeling.

To improve the quality of gluing, it is desirable to also perform a pressure roller with heating to a temperature of 70-80 °.
