Definitions

  • patents 5043033, 5649398, and 5657595 are effective and can be 5 performed with little intrusion on the occupants and visitors of the building being reinforced.
  • a disadvantage to these methods is that they use some specialized materials that are not readily available in all locations. As a result, the materials are shipped from centralized distribution centers, sometimes to remote locations that are difficult to reach. The shipping and round transportation of heavy 0 materials adds significantly to the cost of the project.
  • Another disadvantage of the wrapping methods is that the materials readily available on the market are not good matches in color and texture with old buildings. There are many buildings all over the world that are constructed of native stone, brick from local clay, or that are coated with plaster made with local minerals. As a result, the materials of the methods mentioned above, such as epoxy and fiberglass, may not match the color or texture of a given building.
  • the textile could be coated with an inorganic hardenable paste such as mortar.
  • inorganic mortars are alkaline and tend to degrade ordinary fiberglass.
  • Special alkaline- resistant glass textile is available, but is quite expensive. This has discouraged the use of glass textile with mortar for reinforcement of structures.
  • Graphite carbon or aramid fiber textiles would be compatible with mortar, but these textiles are also very expensive and not widely available in all countries.
  • the textile is composed of fibrous basalt, which is resistant to alkaline and compatible with inorganic mortar.
  • the textile is typically an open-weave fabric that is strong and ductile.
  • the fabric is attached to the structure in a ductile manner, such as with fiber anchors as taught in US patent 7207149.
  • the fiber anchors are preferably also created from basalt fiber.
  • a mortar finishing material is mixed, beginning with a hardenable liquid matrix, such as slurry of calcined mineral particles that harden to create a solid mortar after being mixed with water.
  • a hardenable liquid matrix such as slurry of calcined mineral particles that harden to create a solid mortar after being mixed with water.
  • Grit, aggregate, or both are added to the hardenable liquid matrix.
  • the grit or aggregate add color and texture to the mortar finishing material.
  • the reinforcing system is intrinsically fire resistant and does not increase the fire risk to a structure.
  • Figure 1 is a top plan view, partly cut away, of the reinforcement system of the present invention, as used to strengthen a wall of a building.
  • Figure 3 is a top plan view of the reinforcement system of the present invention, as used to strengthen an expansion joint of a structure.
  • Figure 4 is a sectional view, taken on line — 4 of figure 3.
  • Figure 1 is a top plan view of the reinforcement system 10 of the present invention, partly cut away.
  • Figure 2 is a sectional view of reinforcement system 10, taken on line 2— 2 of Figure 1 , as used to strengthen a structure 100, for example a wall 110 of a building.
  • Reinforcement system 10 include alkaline-resistant textile 20 stretched over wall 110. Textile 20 is attached to wall 110 with a plurality of fiber anchors 30. A mortar 50, containing mineral products preferably obtained in the same geographic region as structure 100, is spread over textile 20 and fiber anchors 30.
  • alkaline-resistant fibers with good ductility and high tensile strength may be used to create textile 20 in place of basalt.
  • the choice of specific fiber for textile 20 may be made for each application based upon availability, strength, and cost. Basalt is found to be the preferred material at this time, but other materials may become available in the future.
  • Textile 20 is stretched over surfaces of various structural elements of a structure 100 to be reinforced. Panels of textile 20 may be wrapped over interior or exterior corners so as to connect different walls 1 10, or to connect a wall 110 to a ceiling, or other combinations as appropriate. Textile 20 may be temporarily attached to wall 1 10 by suitable clips, staples, or adhesive.
  • the mesh opening size be small, such as 0.5 inch across.
  • Fiber anchors 30 are created by boring a hole through an opening in textile 20 and into the underlying wall 1 10. A length of fiber roving, preferably also composed of fibrous basalt, is inserted into the borehole with a free end extending above textile 20.
  • a backfill material such as grout or polymeric adhesive
  • the free end of the roving is attached to the outer surface of wall 1 10 and over textile 20, such as with adhesive or mortar.
  • the backfill material retains the roving within the borehole such that fiber anchor 30 forms a sort of large pin attaching textile 20 to wall 110.
  • Fiber anchor 30 is the most preferred ductile connecting means for system 10 because fiber anchor 30 spreads forces over a broad area and so is unlikely to pull out from wall 1 10 as a mechanical fastener might, or pull off a section of wall 110 as a surface adhesive might.
  • the final process is to cover textile 10 and fiber anchors 30 with a mortar finish coat 50.
  • Mortar finish coat 50 covers textile 20 so that it will not be damaged by weather, or snagged.
  • Mortar 50 contacts and adheres to the original surface of wall 110 through the openings of the weave of textile 20, embedding textile 20 and helping spread any large lateral forces such as from earthquake or wind.
  • Mortar 50 mechanically holds textile 20 in place near wall 1 10 but cannot entirely take the place of ductile connection means such as fiber anchors 30.
  • Mortar finish coat 50 is largely for creating a uniformly textured and colored surface for the reinforced wall 1 10.
  • Conventional epoxy and glass fiber textile reinforcement typically gives a structure a smoother texture and slightly hazy coloration. Although the epoxy can be covered with paint of other finish, mortar is not advised due to possible degradation of the glass fiber.
  • Mortar finish coat 50 works well for replicating the appearance of original concrete, stucco, or plaster walls 1 10. With additional modeling and coloring work, mortar finish 50 can even replicate the appearance of historical stone or brick walls 1 10.
  • Mortar 50 is customized to suit the structure to be reinforced.
  • mortar 50 is based on a matrix of hardenable paste, such as ductile concrete.
  • Uncured ductile concrete may be termed a slurry, that is, a mixture of solid particles suspended in a liquid, with sufficient viscosity or surface tension that the particles remain suspended for a long time and yield a mixture that can be handled like a liquid or paste.
  • Ductile concrete is not typically used as a finish coat for homes, historical buildings, or other structures where appearance is important but a modern "industrial" look is not desired. However, it is a strong, ductile material that is less likely to crack under lateral forces than standard concrete.
  • Mineral materials obtained locally may include sand, clay, gravel, ground stone, or mineral colorants. Although the minerals used for customized mortar finish coat 50 are described herein as locally obtained, it is to be understood that the mineral materials are to be obtained preferably from the same source as the materials of the original structure. For example, if an historical structure in Indonesia was built originally of imported Italian marble, it may be aesthetically desirable to obtain material from the same quarry in Italy to customize mortar 50 if reinforcing the structure in Indonesia.
  • Expansion joint 122 is a design feature of bridge 120. It is a gap of a few inches width, left between sections of bridge 120 to allow for thermal expansion of the bridge material. The gap of expansion joint 122 is typically filled to provide a smooth surface for traffic.
  • expansion joint 122 must be of a material that is ductile and will not interfere with the function of expansion joint 122.
  • reinforcing system 10 as illustrated in figures 3 and 4 has been found to be a low cost and very effective way of dressing expansion joint 122.
  • a first layer of mortar 50 may be spread on the original wall 1 10 of the structure, then textile 20 attached over the first layer of mortar 50.
  • Fiber anchors 30 are preferably still employed as detailed above. Fiber anchors 30 are preferably installed after the first layer of mortar 50.
  • a second layer of mortar 50 is applied over textile 20 and fiber anchors 30, then finished, also as described above.

Abstract

Cette invention concerne un système et un procédé de renfort de structures, comprenant un textile à base de basalte (20) relié aux surfaces de la structure (100) au moyen de fibres d'ancrage (30). Le textile répartit les forces et accroît la ductilité de la structure. Le textile peut relier de multiples éléments structuraux les uns aux autres, y compris les murs, planchers, colonnes, poutres et toits. Le textile est recouvert de mortier (50) adapté pour correspondre à la couleur et à la texture de la structure en utilisant du gravier, du granulat ou un colorant obtenu sur place. L'utilisation d'un textile à base de fibre de basalte est préférée pour éviter la dégradation du textile provoquée par les composants alcalins du mortier (50).
