Definitions

  • the present invention relates to a method for constructing a building.
  • the present invention also relates to a building.
  • High-rise buildings are typically built-up level by level and this can be time-consuming especially if it is a high rise building.
  • the fit-out and finishes of the building services for example electrical and hydraulic systems, can only be performed after construction of the building. This may further delay the time whereby the tenants can begin occupying the premises.
  • Prefabricated Volumetric Construction is a new method of construction whereby the building, or a part of the building, is fabricated off-site and later brought on-site after it has been assembled to be fitted at its final location.
  • a problem with PPVC is having a method of connecting sections of the building together in a secure manner that is also cost effective. Previously, this has been achieved in a manner that requires fasteners to extend through neighbouring walls to effectively pin them together. The result may not be aesthetically pleasing.
  • PPVC polyvinyl styrene
  • Another problem with PPVC is with the alignment and assembly of the various sections of the building. In assembling the various sections, it is critical that they are aligned so as to ensure structural stability and proper alignment of finishes. It is also important to ensure adequate coupling between the various sections and provide structural continuity in both vertical and horizontal directions.
  • Other issues with existing PPVC technology includes handling, logistics, lifting and water tightness.
  • a method for constructing a building including a first module and a second module including the steps of:
  • a building including a first module and a second module, wherein :

  • the modules 12 are also fitted off-site with windows 16, door frames 18 and balcony railings 19. Additionally, drywall partition frames and boards as well as tiles and floor finishing may be installed off-site.
  • the PPVC module 12 is completed off-site, it is transported on-site and lifted, for example with a tower crane. Preferably, a special lifting frame is used to effectively lift and install heavy modules at the same time ensuring safety.
  • the building 10 is constructed by performing the steps of:
  • each mating surface 20, 22 forms an outer peripheral surface of a side wall 14b, 14c of each module 12.
  • mating surface 20 forms an outer peripheral surface of a side wall 14c of module 12b
  • mating surface 22 forms an outer peripheral surface of a side wall 14b of module 12c.
  • each side wall 14b, 14c includes an array 32 of reinforced bars 34.
  • Each array 32 provides structural strength to each side wall 14b and 14c in terms of flexure and shear.
  • each side wall 14b, 14c includes one of more couplers 36 extending from the array 32 of reinforced bars 34 into the fastening channel 28.
  • the method also includes the step of inserting key bars 38 into the fastening channel 28 proximal to said couplers 36.
  • key bars 38 are placed proximal to couplers 36, for example key bars 38 are placed adjacent or abutting the couplers 36.
  • the modules 12 are installed using alignment control apparatus 40 comprising alignment pins 42 and leveling plate 44 configured in the manner shown in Figure 4.
  • the diameter of the alignment pin 42 is 25 mm.
  • alignment pins 42 are used at the four corners of the top of the modules 12 to control the horizontal lateral movement.
  • the leveling plate 44 has dimensions of 200 X 100 X 16mm and is placed on top of alignment pin 42. A similar plate with dimensions of 200 x 100 x 1mm can be added on top of plate 44 to adjust and control the vertical alignment.
  • the couplers 36 are cable loops 46 that are used to couple side walls 14c and side wall 14b of modules 12b, 12c.
  • fastener 30 is a grout 48 which is poured into the fastening channel 28 between the mating surface 20 of module 12b and the mating surface 22 of module 12c.
  • the cable loop 46 is made of high-strength steel wire ropes according to European standard EN 12385-4: 2002+Al, wire tensile strength Grade 1770 N/mm 2 .
  • the cable loop 46 has mechanical properties of being flexible and also have a high tensile strength as compared to a normal reinforcing bar. By being flexible, the cable loop 46 provides for easy installation as it can be flexed but also has the ability to retain its original shape. With a high tensile strength, the cable loop 46 can have a reduced diameter size.
  • cable loop 46 is affixed to the concrete by means of tying with wires unto a restrainer bar 35 as particularly shown on Figure 7.
  • the grout 48 is high strength non-shrink grout G70 cube strength which conforms to EN445, EN446 and EN447. This allows the fluid to be able to fill cavities and to bond with the side walls 14b and 14c together to allow the system to act as a composite wall.
  • the key bars 38 are substantially within the circular cable loops 46. This is to keep the walls from pulling out from each other.
  • the cross section of the fastening channel 28 is shaped as particularly shown in Figure 7 for providing ease in de-moulding formwork during the casting stage of side walls 14.
  • the shape of the fastening channel 28 could be any shape.
  • the cable loops 46 are within the castellation joints which provide the necessary space for the cable loops 46 and the installation of key bars 38.
  • the preferable spacing of castellation along the width of the wall is determined based on the structural requirements (pin connection) of each wall necessary to provide vertical continuity through the key bars 38.
  • the walls 14b, 14c are preferably 75 to 90mm thick so as to support the top slab 14d and bottom slab 14a during lifting and transportation.
  • the 20mm gap will be site in-fill from top with grouting to make up the overall 200mm thick composite structural wall.
  • the cable loops 46 have mechanical tensile properties appropriate for withstanding tensile forces during normal use.
  • test sample was placed on the universal testing machine in a vertical position and tension load was applied gradually until failure. The maximum load was then recorded. A total of five samples were tested.
  • the grout 48 has mechanical properties that binds (sandwich) each side wall 14b and 14c together as one composite wall to allow the embodiments to be able to withstand structural loads during use.
  • Axial compression test show sample loaded to ultimate load equal to 2 times working load. Additionally, sample did not fail at ultimate test load and there was no delamination observed at the concrete/grout interface. Therefore axial compression test showed that the, sample behaved in a composite manner under axial compression and it has performed satisfactorily beyond the design capacity as an integrated unit and the strength of the grout-interface performed as well as the strength of the concrete.
  • bending test was performed on the sandwiched panels to verify flexural capacity of the panels and determine whether there is slipping issue between the precast panel and infill grout.
  • the sample was loaded to failure and was found to fail by bending with flexural crack lines forming on surface. However, there was no delamination observed at the concrete/grout interface. Therefore bending test found that the sample behaved in a composite manner under bending.
  • pull out tension test was performed to verify the tension capacity between the panels and the grout using different surfaces of concrete to find the best possible rough surface finished that will achieve a high tension capacity.
  • the material used as grout 48 allows the overall system of binding or coupling of the two side walls 14b, 14c together to meet the structural capacity of concrete in terms of bending, axial compression and shear.
  • a higher roughness i.e. indented according to SS EN 19920101 : 2008 may also be used.
  • the couplers 36 of the modules 12b, 12c are U-bars 50 that are used to couple side walls 14c and side wall 14b.
  • fastener 30 comprises grout 48 which is used to fill the fastening channel 28 between the mating surface 20 of module 14c and the mating surface 22 of module 14b.
  • the U-bar 50 is made of high tensile steel bar with yield strength of about 500 N/mm 2 , for example.
  • the U-bar 50 is preferable over cable loops 104 because it is rigid and allows tensile force to be transferred rapidly. In contrast, cable loops 104 may elongate first before acting in tension. Additionally, U-bars 50 are more cost effective compared to cable loops 104.
  • the U-bars 50 are affixed to the precast wall 49 with proper anchorage length by extending out from the array 32 of reinforced bars 34 into the fastening channel 28 as particularly shown in Figure 10.
  • the U-bar 50 of side wall 14c overlaps the U-bar 50 of side wall 14b as particularly shown in Figure 8.
  • the key bars 38 are substantially proximal to the U-bars 50.
  • the table below itemises the grout tension by flexion and compression for each grout batch by testing three grout prisms of dimensions 4 cm x 4 cm x 16 cm.
  • the couplers 36 of the modules 12b, 12c are U-bars 50 that are used to couple side walls 14c and side wall 14b.
  • fastener 30 comprises chipping concrete 52 which is used to fill the fastening channel 32 between the mating surface 20 of module 14c and the mating surface 22 of module 14b.
  • the distance between the mating surface 20 of module 14c and the mating surface 22 of module 14b is at least 50mm for allowing the chipping concrete 52 to flow. Of course the distance can be any other distance.
  • the key bars 38 are substantially proximal to the U-bars 50.
  • Chipping concrete 302 is high strength non-shrink concrete grout G70 cube strength, for example.
  • aggregates are smaller in size and the mix is designed to allow the chipping concrete 302 to flow to fill every cavity. This will allow the chipping concrete 302 to bond to the mating surfaces of each side wall 14b and 14c together to act as a composite wall.
  • Chipping concrete 302 can be used instead of grout 48 to reduce costs.
