Definitions

  • This application pertains to a prefabricated panel for one-way light-weight joist slabs of the compound section type, which combines: an upper contributing layer, a lower contributing layer, and shear bolts or connectors that connect the two components, thereby allowing the panel to operate as a compound section and thereby producing a high-efficiency system for meeting the demands of bending moments and shear forces. Because of the foregoing, these panels have a low per-unit weight compared to existing systems. The foregoing translates into smaller inherent-weight loads and mitigates inertial effects during seismic events, thereby making it possible to use less rugged structural solutions that impose lower demands on the soil and are much more economical. In addition, by eliminating the casting of concrete during the manufacture of the joist slabs, completely in the case of metal structures and significantly in the case of concrete structures, less time and fewer inputs are required: labor and equipment during this activity, thereby reducing cost.
  • Construction systems for one-way light-weight slabs which account for the majority of those produced, include: Light-weight one-way slabs with blocks or caissons (1), as shown in Figure 1 , which depicts a general cross-section of a slab that is produced using this system.
  • the lightening elements (11) can be: blocks of clay, concrete, or mortar, caissons made of expanded polystyrene (ICOPOR) or guadua [Translator's note: a type of South American bamboo], and in general elements that make up a system with a low specific weight and that can be incorporated into the slab or can be removed after the concrete cures.
  • This system maintains a small separation between the joists (12) or length of the sheet (13), where the separation distance or width (A) of the lightening element along the sheet is between 300 and 800 mm.
  • the per-unit weight of the sheet is 120.0 kg/m 2 .
  • Managing the smallest separation between joists ensures that the slab: sheet + joists is the solution with the best weight per unit of surface area.
  • This category of joist slab manages per-unit weights within the range of 300-600 kg/m 2 .
  • the compound-section system formed by a contributing layer or steel deck + concrete (2) is shown in Figure 2 , which depicts a longitudinal section Figure 2A and a cross-section of the system Figure 2B .
  • the contributing layer (21) performs two functions; first, as a form for receiving the concrete (22) while it cures, and second, once the concrete has cured, the ridges formed in the layer prevent the concrete from slipping and force it to work therewith in an integral fashion, thus creating a compound system.
  • the maximum gap (B) or separation between joists (23) of this sheet is equal to or less than 2.5 m.
  • the weight of the sheet per square meter varies depending on the height of the concrete and the thickness or size of the contributing sheet or steel deck that are combined. This kind of joist slab keeps per-unit weights between 187.0 kg/m 2 and 286.0 kg/m 2 .
  • the system consists of "U"-section steel joists (31) which, during the casting of the slab, are filled with concrete, are separated by a gap of 800 mm, and support the "sheet” that is formed with clay blocks (32) having a length (A) of 800 mm and a per-unit weight of 60.0 kg/m 2 .
  • the addition of a concrete coating (33) measuring 40 mm and electric-welded mesh to the "sheet” determines its per-unit weight, on the order of 96.0 kg/m 2 .
  • this category of joist slab manages per-unit weights of between 206.0 and 268.0 kg/m 2 .
  • FIG. 4 This system of prestressed prefabricated alveolar sheets (4) is depicted in Figure 4 .
  • This figure shows a cross-section of one type of this sheet for commercial areas.
  • the system consists of slender prestressed sheets (41) made of high-strength concrete and lightened with internal cavities (42) in the form of tubes.
  • the gaps between these sheets are between 2000 mm and 9500 mm, and their inherent weight is between 135.0 and 215.0 kg/m 2 .
  • the weight per square meter of this category of slab lies between 241.0 and 255.0 kg/m 2 .
  • the systems currently in use require in-situ concrete casting, except for prestressed alveolar sheet system.
  • the range of weights per square meter of the slab systems currently in use is between 206.0 and 600.0 kg/m 2 .
  • the advantages of this system include: connecting in its entirety ordinary concrete to the light concrete via a steel frame, thereby reducing the weight of the floor.
  • the integrity of the overall unit is increased, and the use of the lower profile makes it possible to protect the light concrete, thus enhancing the load-bearing capacity of the structure and thereby improving the durability of the lightened concrete.
  • this system is not only very heavy, but it also requires a complex combination of profiles and frames that have to be installed on-site.
  • prefabricated sheets are cited in the Colombian application 06 - 018544, which discloses prefabricated concrete sheets for creating flat surfaces for tracks and roads; said sheets comprise a body or volume with a quadrilateral outline and interior metal reinforcement along with some means for connecting to adjacent sheets of the same type.
  • Said means for connecting to adjacent sheets of the same type consist of a metal plate with angular end folds and anchoring screws. These metal plates connect the adjacent sheets like a bridge, with being anchoring screws secured close to their respective shared edges.
  • the system described above focuses on the way in which the prefabricated sheets can be connected. In no way does this system make it possible to reduce the weight of the sheet and retain a variable range of resistance to shearing and compression forces that makes it possible to withstand bending due to turning moments or tendencies to turn that can arise at any time.
  • CN201424725 refers to a prefabricated concrete sheet with a metal section, which comprises a lower sheet of reinforced concrete, an upper sheet of concrete, and two longitudinal concrete bars that are supported between the upper and lower sheets by means of holes arranged on the sides of the longitudinal bars; a sheet on the ground is formed by cutting and joining multiple pieces of prefabricated reinforced-concrete sheets; a steel reinforcing bar extends through holes arranged in the sides of the longitudinal bars in order to connect to the different prefabricated pieces; later, concrete is cast in order to fill and level the hollow cavities formed between the longitudinal bars, thereby reducing the dead weight of the floor sheet and extending its service life.
  • application FR19980000526 refers to a panel that has a sound-absorbing parallelepiped shape (3).
  • the assembly has parallel vertical ribs (30) with a trapezoidal cross-section.
  • the lower face of the connecting section is flat.
  • This construction element is essentially characterized by the fact that it is an essentially rectangular parallelepiped and that it is made up of two parts, a connecting part and a sound-absorbing part, which is located on the sound-emission side and has vertical and parallel thickness ribs with a trapezoidal cross-section, while the upper face of said connecting part is located in the same plane as the upper face of said absorbing part and has a longitudinal recess for receiving the mortar, etc., and the lower face of said connecting piece is located in the same plane as the lower face of said absorbing part, is flat [sic, incomplete or run-on sentence].
  • This construction element has a part that protrudes from the lateral edge, which has a vertical notch for receiving a compressible joint.
  • the connecting part comprises at least one wide vertical channel shaft for receiving mortar, etc. in order to ensure the construction of the wall.
  • the compound-sheet panel (5) of this invention was designed as a prefabricated panel for the field of sheets made of one-way light-weight slabs.
  • said panel is composed of an upper layer (51) of the cement type and/or polymer resins, cured, with thicknesses of between 15 and 20 mm, a compressive strength of between 27 Mp and 28 Mp, and a specific weight of between 1550.0 and 1600.0 kg/m 3 ; hereinafter this layer will be referred to as the upper contributing layer (51), and a lower contributing layer (52) made of cool-roll (CR) steel, which is among the references described in section A.3.1 of standard AISI 1996 and which has a thickness of 0.6-1.2 mm, or which is made of cold-rolled stainless steel having a thickness of between 0.5 and 0.8 mm.
  • CR cool-roll
  • FIG. 6 The cross-section of said panel is depicted in Figure 6 , which shows that the lower contributing layer (52) features a series of upper peaks (521) and valleys (522).
  • the upper contributing layer (51) is secured by shear bolts or pins (53) working in shear and compression on the upper peaks (521) of the lower contributing layer (52), while the valleys (522) are connected by means of shear bolts or pins (53) to the slab (7) lattice beam, which can be made of steel or concrete.
  • the shear bolts or pins (53) take up the shear stresses that are generated by the integrated operation of the system under shearing conditions.
  • FIG. 7 depicts the lower contributing layer (52) in detail and independently.
  • said layer includes the peaks (521), which have a width (h) that varies between 100 and 150 mm, a width (a) of 185-250 mm, a peak-to-peak distance (b) of between 190 and 260 mm, and which have at each of the ends of the lower contributing layer (52) a horizontal flange (54) whose length is 20 mm.
  • the selection of the upper contributing layer (51) will be determined by resistance to compression and shearing stresses according to the LRFD [Load and Resistance Factor Design] design method, standard ACI. Both contributing components (51, 52) must comply with verification of [Translator's note: this should perhaps be "guarantee resistance to”] the compression stresses generated by the shear bolts or pins (53).
  • the sheet panel of this invention is conceived of as prefabricated and operating under conditions of simple support, on the system of beams of the slab (7), where the panel is secured to the beams by means of attachments or shear connectors consisting of fired bolts and/or nails, joining the lower contributing layer (52) to the upper face of the support beam (7), which is made of concrete or steel.
  • the inherent weight of the panel varies between 40.0 and 48.0 kg/m 2 .
  • the weight per square meter of this slab system is between 108.0 and 116.0 kg/m 2 .
  • Example 1 Arrangement of the sheet panels (5) on the lattice of beams (7) of the slab.
  • the integrated working of the set of panels (5) as a system of flat beams is achieved by virtue of the fact that the shear bolts or pins (53) depicted in Figure 10 work on shear: "Section A-A Figure 9 ".
  • the shear bolts or pins (531) guarantee the transfer of shear forces in order to ensure integral operation between the upper contributing layer (51) and the lower contributing layer (52), while the shear bolts or pins (532) are responsible for transferring shear forces in order to guarantee integral operation between sheet panels (5), thereby avoiding cracks between joints.
  • These shear bolts or pins (532) keep different levels of deflection from arising along the longitudinal lines that delimit the panels (5), thereby preventing the floor finishes from cracking along said lines.
  • Figure 11 depicts a section B-B of Figure 9 .
  • the sheet panels (5) that confine the filler would act as skirts.
  • the skids of the lower contributing layer (52) that push against it are secured with appropriately selected shear bolts or pins (53) (bolts of Type A490 for metal beams or epoxy fasteners or fired nails for concrete beams).
  • Figure 11 also shows the column (8) that rises above the sheet panel (5) at the point where the central beam (7A) and the support beam (71) come together.
  • FIG. 12 The way in which the plate panel of this patent application (5) and the support beams (71, 72) interact is presented in Figure 12 .
  • a cut (S) is shown that is made in the upper contributing layer (51) along the edge that strikes against the central axis of the support beam (7) for the purpose of securing the central valley (522) of the lower contributing layer (52) to the support beam (71, 72) by means of shear bolts or pins (533) that are appropriately selected (bolts of Type A490 for metal structures, or epoxy fastenings for concrete structures) as shown in Figures 12 and 13 .
  • the opening that has been made (S) is again closed with epoxy resin, thereby securing the cut segment.
  • the split center joints along the support beams (71, 72) are sealed with a joint filler (9) with a high modulus of elasticity, such as Sikabond T2 or the like (see Figure 14 ).
  • a fire-resistant coating is applied to the lower face of the lower contributing layer; this coating guarantees that the coating will remain stable for at least 120 minutes after a fire starts.
  • the plate panel (5) of this invention is made up of three components:
  • These bolts are of the following type: matchtip Phillips milled-head screw with a diameter of at least 5.5 mm; selection thereof is made in accordance with standard ASIC-LRFD.
  • the sheet panel enhances the moment of inertia of the section by putting the center of gravity closer to that of the upper contributing layer.
