DETAILED DESCRIPTION OF EMBODIMENTS
[0090] Reference is now made to FIGS. 1A-1E which are schematic illustrations of a prefabricated wall 10 as a part of a system for assembling prefabricated walls according to an example of the first aspect of the presently disclosed subject matter, generally designated as 1. The prefabricated wall 10 comprises a frame structure 12 having a resistance layer 14 connected to a face thereof, and a finishing layer 16 connected to an exterior surface 14A of the resistance layer 14. The resistance layer and finishing layer from another opposite face of the frame structure have been removed for illustration purposes. A factory finished exterior surface 16A of the finishing layer 16 constitutes a front face 10A of the prefabricated wall. The factory finished exterior surface of the opposite finishing layer (not shown) constitutes a back face 10B of the prefabricated wall. The prefabricated wall 10 includes two side portions 11 and 11′, a central portion 13 constituted by portions of the front face 10A and back face 10B, a bottom portion 15, and a top portion 17. The side portions 11 and 11′ include respective side faces constituting the side faces 10C and 10D of the prefabricated wall extending between the front face 10A and back face 10B. The bottom portion 15 includes a bottom face 10E of the prefabricated wall 10 and the top portion 17 includes a top face 10F of the prefabricated wall 10, such that the two side faces 10C and 10D extend together with the front face 10A and the back face 10B between the bottom face 10E and the top face 10F.
[0091] The prefabricated wall has anchor pathways 20 and 20′ extending therethrough along a height H of the prefabricated wall and each between respective top openings 20A and 20A′, formed in the top face 10F and respective bottom openings 20B and 20B′ formed in the bottom face 10E. In the illustrated example, the prefabricated wall 10 has a width W significantly longer than a thickness T thereof, and there are two anchor pathways 20 and 20′ extending through side portions 11 and 11′. The anchor pathway 20 has a first dimension D1 in a direction along the width W of the prefabricated wall 10, and a second dimension D2 in a direction along the thickness T of the prefabricated wall 10. In the illustrated example, the anchor pathway 20 has uniform dimensions D1 and D2 throughout the length of the anchor pathway 20 along the height H of the prefabricated wall 10. In other examples, the top opening 20A and the bottom opening 20B can have different dimensions than the rest of the anchor pathway. For instance, the top opening 20A and the bottom opening 20B can be narrower than the rest of the anchor pathway 20.
[0092] In some examples (not shown), the prefabricated wall can be in the form of a column having thickness and width substantially similar, and can have only one anchor pathway extending therethrough.
[0093] Reference is now made to FIGS. 2A-2E which are schematic illustrations of system 1 depicting assembling of the prefabricated wall 10. FIG. 2A shows a base support element 22 having a first anchoring element 24 with its first end 24A connected thereto. A second end 24B of the first anchoring element 24 is coupled to first end 26A of a second anchoring element 26 via a coupler 28. The coupler 28 can be a coupler nut having two threaded portions at two ends each configured to be coupled to the first and the second anchoring elements respectively. Although FIG. 2A depicts another first anchoring element 24′, another second anchoring element 26′ and another coupler 28′ with same features as those of the first anchoring element 24, second anchoring element 26 and coupler 28, only the first anchoring element 24, second anchoring element 26 and coupler 28 have been described in detailed for the purpose of clarity.
[0094] As can be seen in FIG. 2B, the system 1 further includes an alignment element 30 connected to the base support element 22 such that the first anchoring element 24 passes through a base portion 31 of the alignment element 30 and is locked at the alignment element 30 by a lock nut 27. The alignment element 30 is configured to be received into and align the bottom opening 20B and thus the prefabricated wall 10 into its exact position while it is lowered, as detailed further herein below.
[0095] FIG. 2C depicts the system 1 with the prefabricated wall 10 having been lowered onto the base support element 22 while slidingly receiving the first anchoring element 24, the first end 26A of the second anchoring element 26, and the coupler 28 within the anchor pathway 20 through the bottom opening 20B. As can be best seen in FIGS. 2D and 2E, a second end 26B of the second anchoring element 26 protrudes from the top opening 20A of the anchor pathway 20.
[0096] The system 1 includes another alignment element 30 positioned at the top opening 20A of the anchor pathway 20 such that a through-opening 31A formed in the base portion 31 of the alignment element 30 is aligned with the top opening 20A. The second end 26B of the second anchoring element 26 passes through the through-opening 31A and is locked at the top opening 20A by a locking element 25. The locking element 25 includes a washer plate 25A placed over the base portion 31 of the alignment element 30, a lock nut 25B and a jam nut 25C. The second end 26B of the second anchoring element 26 can constitute a first anchoring element for another top prefabricated wall to be received on the top of the prefabricated wall 10, and the other alignment element 30 positioned at the top opening 20A can be configured to align the bottom opening of the anchor pathway of the other top prefabricated wall. The second end 26B of the second anchoring element 26 has a guiding tip 26C removably connected thereto and configured to assist the guiding of the second end 26C through the anchor pathway 20, the top opening 20A, and the through-opening 31A.
[0097] The system 1 further includes a guiding element 40 positioned within the anchor pathway 20 in proximity to the top opening 20A. The guiding element 40 has a lower end portion 40A, an upper end portion 40B narrower than the lower end portion 40A and positioned adjacent and aligned with the top opening 20A and the through-opening 31A of the alignment element 30, and an intermediate portion 40C extending between the lower end portion 40A and the upper end portion 40B.
[0098] Reference is now made to FIGS. 3A-3C to describe in detail the structure of the alignment element 30 and guiding element 40 according to an example of the presently disclosed subject matter. FIGS. 3A and 3C illustrate the alignment element 30 and the guiding element 40 integrally formed with each, whereas FIG. 3B illustrates the alignment element 30 and the guiding element 40 having been manufactured separately and connected together. The alignment element 30 has the base portion 31 having the through-opening 31A, and an aligning portion 32 extending from the base portion 31. The aligning portion 32 includes two main aligning plates 34 extending from and perpendicular to the base portion 31. The main aligning plates 34 have edges 35 converging in a direction away from the base portion 31. The slope of the convergence is a gradient slope. In other examples, this slope can be a constant slope. A maximum distance D3 between the edges 35 of each of the main aligning plates 34 corresponds to respective dimension of the bottom opening 20B, which in the illustrated example is D1. When the prefabricated wall 10 is being lowered, or during upliftment of the prefabricated wall 10 in a seismic event, the bottom opening 20B slides on the edges 35 and gets aligned precisely over the alignment element 30 in the direction along the width W of the prefabricated wall 10. Each main aligning plate 34 has internal surface 34A, and opposite external surface 34B having auxiliary aligning plates 36 extending perpendicularly therefrom. The auxiliary aligning plate 36 has edge 37 sloped away from the main guiding plate 34 in a direction towards the base portion 31 of the aligning element 30. The slope of the edge 37 is a gradient slope. In other examples, the slope of the edge 37 can be a constant slope. A maximum distance D4 between the edges 37 of the auxiliary aligning plates 36 of the two main aligning plates 34 corresponds to respective dimension of the bottom opening 20B, which in the illustrated example is D2. When the prefabricated wall 10 is being lowered, or during upliftment of the prefabricated wall 10 in a seismic event, the bottom opening 20B slides on the edges 37 and gets aligned precisely over the alignment element 30 in the direction along the thickness T of the prefabricated wall 10.
[0099] The lower end portion 40A of the guiding element 40 has a dimension D5 along the width W of the prefabricated wall 10, that corresponds to the respective dimension of the anchor pathway 20, i.e., D1. The lower end portion 40A of the guiding element 40 has a dimension D6 along the thickness T of the prefabricated wall 10, that corresponds to the respective dimension of the anchor pathway 20, i.e., D2. As can be seen the best in FIG. 3C, the upper end portion 40B of the guiding element 40 has dimensions that corresponds to those of the through-opening 31A of the alignment element 30. In examples where the top opening 20A is narrower than rest of the anchor pathway 20, the dimensions of the upper end portion 40B of the guiding element 40 corresponds to those of the top opening 20A. While the prefabricated wall 10 is being lowered, the dimensions of the guiding element 40 causes the guiding element 40 to guide the second end 26B of the second anchoring element 26 through the top opening 20A and the through-opening 31A of the alignment element 30.
[0100] FIG. 3D illustrates an alignment element 30′ according to another example of the presently disclosed subject matter. The alignment element comprises a base portion 31′ having a through-opening 31A′, and an aligning portion 32′ extending from the base portion 31′. The aligning portion 32′ has a bottom end 32A′ connected to the base portion 31′ and having a dimension D7 to be positioned along the width W of the prefabricated wall that corresponds to the respective dimension of the anchor pathway 20, i.e., D1. The bottom end 32A′ has a dimension D8 to be positioned along the thickness T of the prefabricated wall that corresponds to the respective dimension of the anchor pathway 20, i.e., D2. The aligning portion 32′ converges in a direction away from the base portion 31′ such that a top end 32B′ thereof is narrower than the bottom end 32A′. The slope of the convergence is gradient slope. In other examples, the slope can be a constant slope. When the prefabricated wall 10 is lowered, the slope of the aligning portion causes the bottom opening 20B to be aligned precisely with the alignment element 31′. The top end 32B′ has a through-opening 31B′ configured to allow the first anchoring element 24 and/or the second anchoring element 26 to pass therethrough.
[0101] FIG. 4A schematically illustrates a sequence of assembling the prefabricated wall 10, according to an example of the presently disclosed subject matter. As shown in FIG. 4A, first of all the first anchoring elements 24 are connected to the base support element 22 followed by coupling the second anchoring elements 26 thereto via the couplers 28. After installing the first and the second anchoring element, the prefabricated wall 10 is lowered onto the base support element 22 while receiving the second end 26B of the second anchoring element 26, the coupler 28 and the first anchoring element 24 into the anchor pathway 20 via the bottom opening 20B. Then the second end 26B of the second anchoring element 26 is locked at the top opening 20A by the locking element 25.
[0102] FIG. 4B schematically illustrates a sequence of assembling the prefabricated wall 10, according to another example of the presently disclosed subject matter. As shown in FIG. 4B, first of all the first anchoring elements 24 are connected to the base support element 22. The second anchoring element 26 with the coupler 28 connected to the first end 26A thereof is inserted into the anchor pathway 20. Then the prefabricated wall 10 is lowered up to just above the first anchoring element 24, and the second anchoring element 26 is lowered so as to be coupled to the first anchoring element 24. After coupling the second anchoring element 26 and the first anchoring element 24, the prefabricated wall 10 is completely lowered onto the base support element 22. Then the second end 26B of the second anchoring element 26 is locked at the top opening 20A by the locking element 25. As shown in FIG. 4C, the second anchoring element 26 can be lowered and coupled to the first anchoring element 24 by a special tool 45 connected to the second end 26B of the second anchoring element 26. The tool 45 can be used to thread the second anchoring element 26 with the first anchoring element 24 via the coupler 28, and then can be disconnected from the second anchoring element 26. The tool 45 has a safety cable 45A configured to secure the tool 45 to the prefabricated wall 10 during operation thereof.
[0103] In some examples of any of the alternative sequences, an alignment element (not shown) can be positioned at the base support element 22 after connecting the first anchoring element 24 and prior to coupling the second anchoring element 26 thereto. In some examples of any of the alternative sequences, a guiding element (not shown) can be positioned in the anchor pathway 20 in proximity to the top opening 20A prior to lowering the prefabricated wall 10. In some examples of any of the alternative sequences, an alignment element (not shown) can be positioned at the top opening 20A either prior to or after lowering the prefabricated wall 10, but prior to locking the second end 26B.
[0104] Although the above description has been provided with reference to one prefabricated wall 10, it is to be understood that in the similar manner, more prefabricated walls can be assembled one above other, and the above description applies to such an assembly. The prefabricated wall 10 can be the bottom most wall of the whole assembly, a middle wall, or can be a top wall configured to be assembled in the similar manner on the top of a bottom prefabricated wall. The first anchoring element and the alignment element for the bottom most wall is connected to the base support element. The second end of second anchoring element of every bottom wall constitutes a first anchoring element for its top wall. The alignment element positioned on top of every bottom wall constitutes the anchoring element for aligning its top wall. All the prefabricated walls have to be identical at least in the manner to have the anchor pathways similar to the anchor pathway 20 described above.
[0105] Reference is now made again to FIGS. 1A-1E for describing the system 1 according to the second aspect of the presently disclosed subject matter. The system 1 further comprises a first engaging member 60 connected to a side face 10D of the prefabricated wall 10. The first engaging member 60 includes three protrusions 60A, 60B, and 60C extending from the side face 10D. The protrusions 60A-C can be integrally formed with the frame structure 12 or can be separately manufactured and mounted to the frame structure 12. In some examples, the first engaging member 60 can be just one protrusion extending along the height H of the prefabricated wall 10. Each of the protrusions 60A-60C has respective protrusion tops 62A-62C and two protrusion sides 64A-64C and 64A′-64C′ extending between the prefabricated wall 10 and the protrusion tops 62A-62C.
[0106] The system 1 further includes another first engaging member 70 connected to the bottom portion 15 of the prefabricated wall 10. The other first engaging member 70 includes a plurality of recesses 70A-70J extending into the prefabricated wall 10 from the bottom face 10E. The recesses 70A-70J can be integrally formed with the frame structure 12 or can be separately manufactured and then mounted to the frame structure 12. In some examples, the other first engaging member 70 can be just one elongated recess extending along the width W of the prefabricated wall 10. The recesses 70A-70J have respective recess bases 72A-72J and two recess sides 74A-74J and 74A′-74J′ extending from the recess bases 72A-72J.

[0108] The second engaging member 80 includes three recesses 80A, 80B, and 80C connected to the side face 10C. The recesses 80A-C can be integrally formed with the frame structure 12 or can be separately manufactured and mounted to the frame structure 12. In some examples, the second engaging member 80 can be just one recess extending along the height H of the prefabricated wall 10. Each of the recesses 80A-80C has respective recess bases 82A-82C and two recess sides 84A-84C and 84A′-84C′ extending from the recess bases 82A-82C.
[0109] The system 1 further includes another second engaging member 90 connected to the top face 10F of the prefabricated wall 10. For the simplicity of description, the second engaging member 90 is described with reference to the prefabricated wall 10, and the second engaging member 90 is configured to be connected to either a bottom wall or the base support element 22 and to engage with the other first engaging member 70, as detailed herein below with reference to FIGS. 6A and 6B. In other words, the other second engaging member 90 is configured to engage the other first engaging member connected to a top prefabricated wall to be assembled on top of the prefabricated wall 10.
[0110] The other second engaging member 90 includes a plurality of protrusions 90A-90J extending from the top face 10F of the prefabricated wall 10. The protrusions 90A-90J can be integrally formed with the frame structure 12 or can be separately manufactured and then mounted to the frame structure 12. In some examples, the other second engaging member 90 can be just one elongated protrusion extending along the width W of the prefabricated wall 10. The protrusions 90A-90J have respective protrusion tops 92A-92J and two protrusion sides 94A-94J and 94A′-94J′ extending between the prefabricated wall 10 and the protrusion tops 92A-92J.
