Description

Roofing footpath refers to the field of construction, in particular to flat roofs, and is designed to provide safe and comfortable pedestrian access to the surface of the roofing membrane during installation and its subsequent operation in all weather conditions.

The pedestrian walkway protects the roofing membrane from possible damage during its operation and allows for a safe approach by maintenance personnel to ventilation, technical and other structures for the finished roofing membrane. The special pattern, profile and depth of the ribs provide maximum anti-slip and drainage effects on the working surface of the roof walkway.

A device for a roofing footpath (Sarnafil PVC Walkway Pad, see link http://gbr.sarnafil.sika.com/en/solutions_products/sarnafil-roofing-accessories/walkways.html or http: //gbr.sarnafil.sika. com / en / system / search.html? _charset_ = utf-8 & q = walkway + pad), made in the form of rectangular plates, each of which contains on the outer surface a square field with edges located in the form of chevron rows and vertical borders delimiting field from vertical and thin side strips, on each of which are placed vertically in a row three through vertical square holes communicating with the network drainage channels located on the inner surface of the plate.

The presence on the footpath of vertical sides delimiting the field with ribs from lateral smooth and thin strips, and the height of the sides exceeding the height of the ribs make it difficult to drain and remove snow and ice in the transverse direction from the field surface with the ribs of the device.

The angle of inclination (about 90 degrees) between adjacent ribs of adjacent chevron rows also affects drainage along the ribs and the conditions for mechanical cleaning of snow and ice in the transverse direction of the field with ribs.

Also known is a roof walkway device (LOGICROOF WalkWay Puzzle by TECHNONICOL company, see link http://www.tn.ru/catalogue/dopolnitelnye_element2/loqicroof_walkway_puzzle_dlja_sozdanija_dorozhek/ or http://loqicroof.ru/components/roaya/ropozhnaya for the prototype, made in the form of a series of rectangular plates, each of which has a square field with ribs placed in the form of chevron rows, and two side and smooth stripes, on which are placed three in a row through square holes communicating with the channels of the drainage network located on the inside of the plate.

The disadvantage of the roofing footpath is insufficient anti-skid at low temperatures, expressed in the increase in the duration and the difficulty of high-quality mechanical cleaning from snow and ice of the working surface of the device.

The disadvantage is also insufficient drainage and water removal from the working and internal surfaces of the track at positive temperatures under the influence of precipitation.

The objective of the proposed technical solution is to increase operational characteristics by increasing the anti-slip and drainage properties of the track surface.

The problem is solved due to the fact that in the roofing pedestrian walkway, consisting of rectangular plates equipped with docking elements, on each rectangular plate on the outside there is a field with ribs evenly spaced in chevron order, and lateral strips placed through the edges of the field with through vertical holes and on the inner side of the plate there is a network of orthogonal drainage channels communicating at their ends with corresponding through vertical holes, of the invention, the angle of inclination between the ribs of adjacent chevron rows is more than 90 degrees and the cross section of the ribs is made in the form of a trapezoid, and at least two pairs of slotted transverse holes are made on each rectangular plate made along the width of the central drainage channel, in addition, the roof pedestrian walkway is equipped with a thermal cable located under the track along its longitudinal axis.

Increasing the angle of inclination formed by the nearest edges of adjacent chevron rows to 120 degrees allows you to:

- when it rains, improve drainage by facilitating the passage of rainwater through gutters formed by adjacent ribs;

- to improve the removal of snow and ice due to the formation of a less winding path along the grooves formed by adjacent ribs, and, therefore, increasing the anti-slip properties of the track surface.

The implementation of the edges of the plate of the pedestrian walkway with a cross section in the form of a trapezoid improves the anti-slip properties of the surface of the track due to the fact that, firstly, the mechanical cleaning of snow and ice with the help of manual tools is facilitated, since the inclined walls of the gutter formed by edges adjacent to the chevron along with it, they facilitate the “release” from snow and ice, and secondly, the cleaning time is reduced. In addition, the trapezoidal cross-section of the ribs has greater strength than a rectangular one, especially when cleaning with a manual inventory of shock loads, which improves performance, namely, increases the safety and increases the durability of the track.

The execution of two pairs of slotted transverse holes made across the width of the central drainage channel allows the thermal cable to be fixed inside the drainage channel located along its longitudinal axis, which makes it possible to heat up the track plate and to ensure effective drainage of water from the longitudinal axis to the side edges of the track.

The use of a thermal cable under the track in the central drainage channel can significantly reduce the drying time after rain, and at negative temperatures in the conditions of precipitation in the form of snow it makes it possible to melt snow and, therefore, remove water from the surface of the field with ribs and keep the track dry.

When ice is formed, heating the track speeds up the mechanical cleaning process due to the thawing of ice in the grooves formed by adjacent ribs and, therefore, facilitating the removal of ice during mechanical cleaning using manual tools (plastic shovel, shovel cuttings, brushes, etc.).

The use of a thermal cable allows, in addition to the possibility of heating the track in the cold season, to provide an additional slope of the track plate from the longitudinal axis to the edges, forming two surfaces of the water slope, which significantly improves drainage from the working pedestrian surface.

Laying the thermal cable along the central longitudinal channel of the plate allows to reduce the drying time and to guarantee high-quality drying of the cavities of the network of drainage channels of the inner side of the track.

The roof walkway consists of such a number of plates that provides the necessary routes for staff to move along the roof membrane of the structure.

The roof footpath plate is on the outside a rectangular base of 750 × 600 mm in size, with a working area of 600 × 550 mm in size, consisting of evenly spaced ribs in the form of chevron vertical rows forming an anti-slip surface, and on the inside there is a network of orthogonal drainage channels, communicating at their ends with corresponding through vertical holes located vertically in a row on the lateral smooth and thin stripes of the plate.

The roof pedestrian walkway consists of rectangular plates 1 provided with four connecting elements 2 and 3 in the form of two semicircular protrusions 2 (see Fig. 5) on the upper connecting edge and two reciprocal semicircular cavities 3 (see Fig. 4) on the lower connecting edge plate 1, forming during installation of the spike-groove joint connection between adjacent plates 1.

Each rectangular plate 1 contains on the outside a working field on which ribs 4 are uniformly placed in the chevron order, forming an anti-slip surface, and two lateral smooth and thin strips 5, each of which has four through vertical holes 6 of square cross-section, arranged vertically in a row see fig. one.

On the inner side of the plate there is a network of mutually orthogonal drainage channels 7 communicating at their ends with corresponding through vertical holes 6, see section EE in FIG. 2 and in FIG. 7.

In FIG. 3 shows a side view of the edge of the plate 1, which shows the extreme drainage channel of the network 7 and the lateral smooth and thin strip 5.

The angle of inclination between the ribs 4 of adjacent chevron rows is 120 degrees, see FIG. 8, and the cross section of the ribs 4 is made in the form of a trapezoid, see FIG. 9.

On each rectangular plate 1 there are two pairs of slotted transverse holes 8, respectively close to the upper and lower edges of the plate 1, made across the width of the central drainage channel 7 and forming two fixing loops during installation, see FIG. 1 and FIG. 6.

The track plate is also equipped with two welded petals 9 located as a continuation of the lateral smooth and thin strips 5 at the opposite edges of the plate 1, that is, beyond the size of the plate.

In addition, the roof walkway can be equipped with a thermal cable 10 located under the track along its longitudinal axis.

Depending on the requirements for pedestrian walkways on the roofing membrane, it is possible to mount a pedestrian walkway with or without heating cable 10.

When mounting without a thermal cable 10, the rectangular plates 1 of the footpath are laid along the entire length of the straight section. Using the connecting elements 2 and 3 in the form of semicircular protrusions 2 and semicircular hollows 3, forming two spike-groove connecting joints between adjacent plates 1, they align in a straight line of all plates 1 to each other. After that, using welded lobes 9 and a manual welding machine, the adjacent elements of the plates 1 of the pedestrian walkway are temporarily fixed to each other. As a result of the installation, a single composite structure is obtained with smooth transitions between the semicircular protrusions 2 and the semicircular cavities 3 of the spike-groove docking joint. Also, to fix the direction of the pedestrian path, a tack is made to the base in the form of a membrane roof.

The welded petals 9 must be positioned so that they do not interfere with the passage of the automatic welding machine along the entire formed boundary of the track ready for welding.

Further, using special side smooth and thin strips 5 along each plate 1 of the track, on which there are no ribs 4 and a network of drainage channels 7, and using a self-propelled welding machine, a straight section of the pedestrian walkway is welded to the roof membrane.

A self-propelled welding machine is installed at the beginning of a straight section of the track and after setting the welding temperature corresponding to weather conditions and the type of membrane in a semi-automatic mode, the welding process starts on one side of the track. As a result of this procedure, a weld is formed with a width of up to 100 mm from one of the sides of the track. This procedure must be repeated from the second side of the track.

To obtain a track heating, use a thermal cable 10, which is mounted in each plate 1 of the pedestrian track, provided that they are fixed to each other. The thermal cable 10 must be threaded into the fixing loops located along the longitudinal axis of the track from the upper and lower edges of the plate 1. To do this, by threading the thermal cable 10 along the central drainage channel 7, use your finger to press on the section of the plate 1 between the pair of upper transverse slotted holes 8, which will to the deflection of this section of the plate 1 and will form a fixation loop, into which it is necessary to pass the thermal cable 10, leading it back to the central drainage channel 7. A similar procedure must be done from the bottom a pair of transverse holes 8. Then, using two thorn-groove docking joints, attach a new plate 1 of the track, in which you need to run the thermal cable 10 in the same way. All other procedures are similar to installing the track without the thermal cable 10. Using the thermal cable 10 during installation allows the possibility of heating the track in the cold season to provide an additional slope of the track plate 1 from the longitudinal axis to the lateral edges, which significantly improves drainage from the pedestrian surface.

The work of the roof walkway is as follows.

At an ambient temperature above 0 ° C without exposure to precipitation, the pedestrian path serves as a load balancer on the roofing membrane, in its physical properties approaching the characteristics of the membrane itself, while having increased wear resistance and strength. Due to the greater thickness of the material and increased rigidity, in comparison with membrane coatings, the pedestrian path allows maintenance of technical structures and the roofing membrane without damaging the latter.

When operating in rain conditions, due to the special structure of the field with ribs 4 of the pedestrian walkway, water is self-removed from its surface. In comparison with the existing analogues, the drainage is improved due to the special shape of the ribs 4 on the surface of the track, which have a special trapezoidal shape. The angle of the ribs 4 is 120 ° relative to each other of the adjacent chevron rows, which leads to the formation of clearly defined drainage trenches from the longitudinal axis of the track to its edges. The use of thermal cable 10 when installing a pedestrian walkway allows you to create an additional angle of inclination of the surface of the walkway from the longitudinal axis to the side edges, which improves drainage from the track surface. For water removal of moisture from under the track, its rear side is equipped with a network of drainage channels 7 and through vertical holes 6. Laying along the central longitudinal channel of the thermal cable 9 can reduce the drying time and guarantee high-quality drying of the space under the track.

Installation of a track with a thermal cable improves drainage both from the outer surface, as a result of self-removal of water, and from under the track. After the end of the precipitation, it is necessary to turn on the heating in order to dry the space under the path. Extra track maintenance is not required.

When operating a footpath in difficult climatic conditions, the following options are possible:

At ambient temperatures below 0 ° C, the properties of the pedestrian walkway are similar to the properties of the roofing membrane, but due to the greater thickness of the material the pedestrian walkway is made in comparison with the membrane, the effect of increased resistance to mechanical impacts of pricking and cutting is achieved.

Before using the track in case of heavy rainfall, it is necessary to carry out mechanical cleaning using a hand tool, which is carried out using a brush, broom or plastic shovel with rounded corners. The use of metal shovels is strictly not allowed. Using the above-mentioned tool, it is necessary to clean the surface of the track from snow masses. When using a shovel, clean up to the edges of the field with ribs, then clean the ribs with a broom or brush for the entire length of their protrusion from the track surface. If you have a specialized mechanized tool, you can carry out mechanized cleaning of the track in a short time compared to mechanical cleaning.

Thus, the special structure of the field with ribs 4, in comparison with existing analogues, allows faster and easier to mechanically clean the track surface from snow and ice, which is achieved by increasing the angle between the ribs 4 of the adjacent chevron rows to 120 degrees, as well as due to the cross section of the ribs 4 in the form of a trapezoid.

After clearing the track of snow in case of heating, turn it on.

With a low level of snowfall and the presence of heating, it is possible to refuse mechanical cleaning of the track, for which they limit the supply of power to the heating elements of the thermal cable 10 and begin to operate it as the snow melts.

Without mechanical cleaning of the track and with a small amount of solid loose precipitation on the roof surface, a specially calculated and simulated structure of the field with ribs 4 allows you to distribute snow masses inside the field with ribs 4, which makes the movement along the track safer. The use of a thermal cable 10 in the pedestrian walkway system makes it possible to obtain absolutely safe dry roofing areas for attendants to pass, which do not have ice and snow masses, even in conditions of temperature drops in the region of 0 ° C or in severe frosts.

Before starting operation, when ice masses freeze on the track surface, it is necessary to mechanically destroy the ice crust or detach it from the track surface, then remove small residues with a brush, broom or plastic shovel with rounded corners. In view of the fact that the track is not rigid, it is recommended that mechanical destruction / peeling be carried out using the back of wooden or plastic hand-tool cuttings, after making sure that there are no sharp protrusions on them. The cleaning of the ribs 4 must be carried out for the entire length of their protrusion from the surface of the track.

If there is a heating of the pedestrian walkway, it is possible to refuse mechanical cleaning by supplying power to the heating elements of the thermal cable 10. As the ice masses melt, the track should begin to operate.

Thus, the implementation of a pedestrian walkway composed of plates, each of which on the outside has an inclination angle between trapezoidal ribs of adjacent chevron rows of 120 degrees, as well as two pairs of slotted transverse holes made along the longitudinal axis, making it possible to apply thermal cable laying, can improve performance characteristics by improving anti-skid and drainage of the track surface.
