Definitions
- the field of engineering covering the invention generally belongs to the field of construction, more closely to the field of waterproofing equipment and in particular to the sheet with supporting vertical haunch-reinforced ribs, which is applied for protection against moisture of cultural monuments and buildings of great historical and cultural significance and other structures, regardless of wall thickness and the type of material they are made of, which require great precision in the process of the works.
- the subject matter of the invention is classified and marked with the basic classification symbol E04B 1/62 relating to the insulation of buildings in general, and with the secondary classification symbols E02D 31/02 covering accessories for protection against moisture or underground water, that is, E04F21/00, which defines tools for laying insulation or sealing layers, as well as E04G 23/06, indicating works on existing buildings: e.g. development of a new substructure.
- the technical problem to be solved by the subject invention consists in the following: how to construct a sheet reinforced by haunches positioned at the joints of vertical supporting ribs with the base plate of the sheet and the method of its incorporation in buildings, especially the massive walls of monasteries, churches, palaces (cultural monuments), etc., to achieve permanent horizontal waterproofing and effective protection against capillary moisture and groundwater, characterized by an increased bearing capacity to vertical load of at least 52.8% compared to existing HIO rails, with its installation in the walls done by a certain procedure of protection without gaps making it a consistent load-bearing element that completely takes over load from the upper parts of the building, so that the entire protection procedure is done without deformation, regardless of wall thickness and the type of material from which it is made, and without disturbing the static stability of the building, wall subsidence and cracking, fissures and other damage.
- the disadvantage of this method is the inability to repair massive walls, as well as to repair stone walls and walls of mixed materials: brick + stone + brick due to the appearance of uneven building subsidence and cracking of reconstructed walls, which occurs as a result of incomplete reliance of the cut wall on the knocked in wedges.
- the disadvantage of this method is in the complexity of the work when installing rails, primarily due to the new properties of mortar and the use of additives for fast curing, which makes it difficult to simply press the rails.
- the biggest disadvantage in the application of this method is the inability to adjust the rail height to the height of the cut into which it is fitted, as vertical "T" ends are made on vertical ribs.
- HIO method is based on the horizontal cutting of walls in 20-30 cm sections, with 11-13 mm cut height. In the cuts thus made and cleaned, cement mortar is first injected into which the HIO rails are then stitched and fitted by knocking in one after another.
- This method is protected by patent number 49324B and according to it, the HIO rail is profiled by vertical ribs so that it has a double function: creating a watertight barrier and preventing building subsidence.
- the essence of the invention is the construction of a segmented profiled semi-rigid sheet, made by pulling on a PVC - polyvinyl chloride (hard) extruder with adding of various additives to improve mechanical properties: hardness, tear strength, impact resistance, elasticity, watertightness, for improvement of resistance to various chemical agents (acids, bases, salts), to neutralize thermal influences, as well as with the addition of UV stabilizer for greater resistance to ultraviolet radiation, which, by being inserted into the wall, creates a permanent waterproof barrier, and effectively prevents further capillary moisture of building, with haunches constructed at the junction points of the base plate and vertical ribs to achieve additional consistency, which haunches have been found, by precise tests, to increase the load capacity of the sheet to vertical load by more than 50% compared to the rails in wide use.
- the essence of the invention is also that massive walls of two, three, five and more meters are cut without any restrictions, and for the successful application of hydroisolation it does not matter what type of building materials the building is constructed
- the essence of the invention is also that the invention is particularly applicable for permanent protection against capillary moisture on the massive walls of monasteries, churches, palaces (cultural monuments), etc., where there is minimal tolerance for construction works and where no cracks and damage to the walls resulting from subsidence when performing hydroisolation works are allowed.
- the novelty of the invention is that the process of cutting and creating horizontal openings for inserting the sheet under consideration is performed with diamond cutting tools with minimum noise and vibration, with cuts in the wall almost imperceptible, and by using injected mass of exceptional adhesion a new coupling resistant to seismic disturbance is formed.
- Figure 1 is an axonometric view of the sheet under consideration
- Figure 2 is a cross-sectional view of the sheet under consideration showing the appearance of vertical ribbed supports with reinforcing haunches
- FIG. 3 is a schematic representation of the joining of sheet segments by means of end couplings
- FIG. 4 is an enlarged view of a female coupling
- FIG. 5 is an enlarged view of a male coupling
- Figure 6 is an enlarged detail of a connected coupling of two sheets
- Figure 7 is a schematic view of a sheet inserted into a wall
- Figure 8 is an enlarged view of a female coupling that allows the connection of sheet segments at an angle of 90 °.
- the present invention fully solves the above defined technical problem.
- the segmental waterproofing sheet 1 is constructed in such a way that it consists of a horizontal base plate 2 and a perpendicularly vertically oriented supporting ribs 3 made of the same material as the base plate 2.
- the sheet 1 is constructed e.g. by pulling on a hard polyvinyl chloride extruder with various additives to improve mechanical properties: hardness, strength, tear strength, impact resistance, elasticity, watertightness, to improve resistance to various chemical agents (acids, bases, salts), to neutralize thermal effects, as well as with the addition of UV stabilizer for greater resistance to ultraviolet radiation, with the note that it can also be made of special alloys or other materials that provide sufficient consistency and durability.
- the supporting ribs 3 are constructed integrally, perpendicularly to the base plate 2, they are of the same thickness and are symmetrically equally spaced.
- the spacing between supporting ribs 3 is variable and is determined depending on the load and the static load bearing calculation and their upper edges 4 are convexly rounded, which makes it easier to insert the sheet 1 into a notch made on the wall where the waterproofing is carried out.
- each sheet 1 is sanded to the height of the cut in the segment. This implies that the height of the cut in one segment is not uniform, so it is easiest, fastest and simplest to adjust the height of supporting ribs 3 to the height of the cut before the sheet 1 is incorporated in the treated building.
- the length of sheet 1 may be infinite, but it is determined during incorporation by the width of the wall on which the waterproofing is performed. As the length of the sheet 1 depends on the thickness of walls, their connection is, if necessary, performed by means of male couplings and female couplings 5, 6 at the free ends of the sheet segments.
- the drawings show that the free end of the male coupling 5 is constructed as an integral tubular extension 7 whose outer diameter is slightly smaller than the diameter of the tubular opening 8 made at WO 2021/133181 PCT/RS2020/000002 the center of the female coupling 6, wherein the diameter of the inner opening 11 is equal to the thickness of the wall of the tubular extension 7.
- the female coupling 6, in cross-section has the appearance of a modified "U" profile with arms bent 10 at an angle of 45°, with spacing between them slightly larger than the thickness of the base plate 2.
- this construction of male and female couplings 5, 6 allows for an unbreakable joint, and is achieved by extending the tubular extension 7 of the male coupling 5 through the tubular opening 8 of the female coupling 6, wherein a connector 9 that connects the male coupling 5 to the base plate 2 passes through the bent arms 10 on the female coupling 6.
- Easy connection of the segments of the sheet 1 is made possible by that the couplings 5, 6 are constructed so that the diameter of the tubular extension 7 matches the diameter of the tubular opening 8 increased by 0.50 mm, with the distance between the tips of the arms 10 also increased by 0.50 mm. It should be noted that this type of connecting the sheet 1 significantly increases the speed of waterproofing works, and that the whole process is carried out simply without the use of special tools and does not require special training of handlers.
- the installation of the sheet under consideration does not endanger the local and general stability of the walls, as well as of the building as a whole, or that the HIO rail has a satisfactory compressive strength corresponding to conventional masonry mortars and also a satisfactory rigidity, which provides load transfer without wall subsidence, and after curing of the injected mortar, is a unique coupling which provides wall load-bearing capacity and water-permeability in the wall cut zone.
- Damp walls are completely cut with one of two cutting techniques:
- cutting is carried out through the coupling by means of electric or hydraulic machines having a sword and a saw chain,
- cutting is done using hydraulic machines and diamond wire-saw, with cuts being made according to the given level, regardless of joints. Cutting is done in stages, in segments (phases) about 20-30 cm wide, depending on the type of building and wall condition. Depending on the type of cutting tool and the degree of building material devastation, cuts can have different heights, from 8.00 to 13.00 mm, noting that the cutting height is not uniform in one segment.
- High-adhesion injection grout is injected into the cuts made using a high-pressure pump.
- a damp masonry wall built of brick in lime mortar, wall thickness d 130 cm, is to be hydro-isolated, it is cut through a joint with a diamond wire saw, with a cutting height of 12 mm for this type of machine and cutting tool.
- the cut is then mechanically cleaned of loose particles of mortar or brick, aggregate, and then cement-polymeric mass is injected into the cleaned cut with a high-pressure pump, which after polymerization makes a new joint stronger to vertical and horizontal loads.
- the total width of the plastic semi-rigid sheet profiled by supporting ribs with haunches is L, the length of the sheet may be unlimited, and the height of the ribs R is h.
- the industrial production of the invention in question is possible in factories for the production of plastic objects and equipment, and even in well-equipped craft workshops for the manufacture of plastic products.
- the invention sheet can be made according to the workshop WO 2021/133181 PCT/RS2020/000002 documentation that can be easily made by experts in this field using the descriptions and drawings in this application.
- the invention is suitable for batch production and its use is particularly recommended for the restoration of moisture on massive structures exposed to moisture, such as e.g. monasteries, churches, palaces (cultural monuments), etc.
- the application of the invention is also recommended in other facilities which are unsuitable for use due to moisture and the walls in which become dry after the installation of the sheet, so that the repaired building changes the micro-climate, becoming a healthy environment with significantly increased energy efficiency, since heating dry walls consumes incomparably less heat.
